July 14 2017.Readers ofWhats Hotmay recall the publication of the recent finding of Mayo Clinic researchers of a potential antiaging senolytic effect for fisetin, a compound found in plants that is available as a dietary supplement. On June 2, 2017 inThe Journals of Gerontology Series A, researchers from the Salk Institute reported a reduction in aging-related inflammation and cognitive decline in mice given fisetin.

Acting on earlier findings of a decrease in memory loss in association with fisetin supplementation in mice that were genetically modified to develop Alzheimers disease, Pamela Maher and colleagues tested the compound in a SAMP8 mouse model of premature aging. Three-month-old animals were given diets with or without fisetin for 7 months, during which memory and activity tests were conducted, and levels of proteins related to brain function and responses toinflammationand stress were measured.

"At 10 months, the differences between these two groups were striking," reported Dr Maher, who is a senior staff scientist in Salk's Cellular Neurobiology Laboratory. While mice that did not receive fisetin did poorly in tests of cognitive function and had elevated markers of stress and inflammation, those that received the compound were not noticeably different from untreated 3-month-old SAMP8 mice.

"Mice are not people, of course," noted Dr Maher, "But there are enough similarities that we think fisetin warrants a closer look, not only for potentially treating sporadic Alzheimers disease but also for reducing some of the cognitive effects associated with aging, generally."

"Companies have put fisetin into various health products but there hasn't been enough serious testing of the compound," she added. "Based on our ongoing work, we think fisetin might be helpful as a preventative for many age-associated neurodegenerative diseases, not just Alzheimer's, and we'd like to encourage more rigorous study of it."

JOHANNESBURG (miningweekly.com) With the Tongon gold mine, in Cte dIvoire, operating to plan, West Africa-focused gold miner Randgold Resources has shifted its focus to the discovery of additional reserves and resources.

Tongon continued to ramp up production, tracking the 2017 output target of 285 000 oz of gold, CEO Mark Bristow said in a statement on Monday.

In line with this, the company is seeking to replace depleted ounces and extend the mines life beyond its current four-year horizon.

Bristow previously highlighted the high resource potential of the exploration programme at Tongon.

Meanwhile, with eyes on what Bristow described as potentially the most exciting gold prospect in West Africa, the companys exploration programmes have defined a large target at Boundiali in the Fonondara corridor.

The company has just completed its yearly review of its exploration targets . . . [which also] highlighted very positive results from its other holdings in the country, underlining again Cte dIvoires exceptional prospectivity, Bristow said.

Randgold continues to seek out Tongon life extension prospects - Creamer Media's Mining Weekly

The United Kingdom did more than any nation to pioneer armored warfare, and its Challenger 2 stands amongst the best tanks in the world. The sixty-two-ton tank established a reputation for exceptional toughness during combat in Iraq. But despite being a newer design than the Leopard or Abrams, the Challenger 2 has not been lavished with the extensive upgrades that its NATO peers have, and is generally perceived as having fallen behind.

In January 2017, the Ministry of Defense declared it had short-listed competing proposals from BAE Systems and German Rheinmetall for a modest Challenger 2 Life Extension Program (LEP) to improve the vehicles sensors and fire control computers. While the LEP is meant to increase the Challenger 2s service life until 2035, neither proposal addresses the most glaring issues with the vehicle.

The Challenger 2 entered service only fifteen years after the Challenger 1 in 1983. At the time, it was the first British tank to benefit from state-of-the-art Chobham composite armor, which decisively restored the defensive primacy of modern tanks. However, the Challenger 1 still shared many systems with the preceding Chieftain tank, including a sluggish fire control system. The new tank performed poorly in exercises and suffered from extravagant teething issues. The Ministry of Defense was inspired to sign on to a more thoroughly modernized design in 1989.

Ironically, the Challenger 1 performed brilliantly under actual combat conditions in the Gulf War, destroying 200 to 300 Iraqi tanks without suffering any losses. The Challenger and Abrams were simply more than the Iraqis could handle. The Iraqi army was fielding older Soviet tanks that could not defeat such formidable armorthey might have had a fighting chance if they had improved ammunition. In return, the 120 millimeter guns on both vehicles could effortlessly pierce opposing armor. A Challenger 1 crew even achieved a record long-range shot during the conflict, destroying an Iraqi tank from 3.2 miles away.

But the Challenger replacement was already well underway. Despite its similar appearance, the Challenger 2 that entered service in 1998 had very few parts in common with its predecessor. It featured a longer barrel L30A1 cannon with a longer fifty-five-caliber barrel, and an upgraded composite package known as Dorchester armor, mixed with extra Explosive Reactive Armor (ERA) tiles. The latter type of armor involves metal plates sandwiched with explosives that explode outward against incoming projectiles, diminishing or deflecting the blast of shaped-charge warheads. In addition to the main gun, the crew of four can fire machineguns.

The Leopard 2, Abrams and Challenger are all considered to be broadly similar in capability, but the British design has some distinguishing quirksnotably, it was formerly considered the best armored of the three tanks, but also the slowest with a maximum speed of thirty-seven miles per hour. This latter trait is related to its underpowered 1,200 horsepower engine, compared to 1,500 horsepower powertrains on other top Western tanks.

The Challenger 2 is also noted for being one of the only modern tank design in its weight class to use a rifled gun. A rifled gun allows for greater accuracy, but the spinning motion it imparts leads to lower muzzle velocity, diminishing penetrating power for the kinetic armor-piercing sabot shells favored by most countrieswhich are quite stable anyway. But British tankers in the 1980s were more interested in their own unique form of ammunition, the High Explosive Squash-Head (HESH) which does not depend on kinetic energy for penetration, but still could benefit from the greater accuracy of a rifled barrel. HESH rounds employ a plastic explosive that generates a shock to the interior vehicle, causing metal to spall.

The Challenger 2 soldiered on in the U.S. invasion of Iraq in 2003, where it once again steamrolled opposing tanks around the city of Basra without suffering any losses to hostile fire. The British tank faced the greatest danger from roadside bombs and rocket-propelled grenades. One Challenger 2 was allegedly struck by seventy RPGsand emerged with its crew unscratched. Another survived seventeen RPGs and a Milan missile, and despite the battle damage, was back in combat the next day.

The Challenger 2s reputation for indomitability created somewhat unreasonable expectations. In 2007, it was revealed that a few years back an insurgent using an RPG-29an especially powerful 105 millimeter warheadhad pierced through the belly armor of a Challenger 2 as it crested a dune. The belly armor is one of the weakest points on any tank. The penetrating warhead mauled the drivers footthough the vehicle remained in operational condition and was able to back away from the ambush. Another Challenger 2 was disabled in 2007 by an IED, but restored into operational condition. The only Challenger 2 to be totally destroyed was hit by another Challenger 2 tank by accident.

The Ministry of Defense was lambasted for having tanks that were not actually indestructible, and slightly more reasonably, that they had covered up the initial incident. Afterwards, the ERA armor on the lower front-hull was replaced with heavier Dorchester composite armor. Presently, the armor packages on the Challengers 2 breaks the scales at around seventy-five tons!

Wayne Gooden holding up a photo of his time in the service.

Editors note: The Journals Unsung Heroes series spotlights a local veteran each week from Memorial Day to Veterans Day. If you would like to nominate an Unsung Hero, email news@journal-news.net.

MARTINSBURG Wayne Gooden, 75, is a decorated Vietnam War Veteran with a colorful military history and police background.

Gooden said he remembers his time in the service vividly, entering the military at age 19.

I went into the military at such a young age, Gooden said.

I actually wanted to travel a bit before I went in, but then I just decided to stay in and serve. In 1967, I was sent to Vietnam and once I got there, I was assigned to the food service. After I was there about three months, I decided I wanted to go into combat arms, which was an infantry unit. I served with the infantry unit for about four months. They sent me back to the NCO Academy (Non-commissioned Officer Academy) and once I graduated from there, I heard that they were looking for volunteers for LERPS (Life Extension Refurbishment Program). The LERP is a four-man recon unit and I was with the 4th Brigade, 2nd Infantry Division LERPS. It was a volunteer thing, one assignment and you can quit at any time.

Gooden was awarded the Bronze Star medal for heroism on March 24, 1968 from his commanding officer Charles R. Swiffin, Colonel, GS-Chief of Staff.

I was awarded the Bronze Star award for heroism in connection with military operations against an armed hostile force in the Republic of Vietnam, Gooden said.

Gooden was participating in a long range enemy reconnaissance patrol when the men observed an enemy platoon moving toward their position.

Knowing that contact with the numerically superior enemy force was unavoidable, the team leader deployed his men to the most advantageous positions, assigning Sgt. Gooden with the responsibility of rear security, said Col. Swiffin in a letter recognizing Gooden for his heroic efforts. Throughout the ensuing engagement, Sgt. Gooden prevented enemy soldiers from breaking through his area of responsibility. When a fellow soldiers weapon malfunctioned, Sgt. Gooden gave the man his own rifle. Courageously, he continued to hold his position, using hand grenades against the threatening enemy. Largely through his heroic efforts, the four Americans effectively repelled the enemy platoon. Sgt. Goodens personal bravery and exemplary devotion to duty are in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.

Gooden said he is very proud of his military service.

When I served my first tour over there in 68 everyone knows that was a bad year but I served it proudly, Gooden said. The only way we got out was because of the chopper. It was literally pulling each of us up by our arms. After that, I went back home for a bit, then went to Fort Leonard Wood in Missouri to start training. It was there I decided I wanted to go back to Vietnam, so I asked my commanding officer if I could return and I did. On my second tour, I was assigned to a security outfit and then after four months I decided I wanted to go into law enforcement.

Gooden was then assigned to the U.S. Army Criminal Investigation Command Office as a military police investigator.

I served my tour there, stationed at Fort Bragg, North Carolina, Gooden said. I decided to go back to Vietnam a third and final time to the same CID office. After I finished my tour there, I was awarded the Army Commendation medal twice, for involvement with solving drug cases, things like that. Then I went back to the states for a while. That time I was assigned to the military police school in Fort Gordon, Georgia. I was assigned there because they came up with a formal class for the military police investigators, and I was chosen to help write the first lesson plan for that class.

From there, Gooden went to complete a tour in Germany, and from there he landed at Fort Knox, Kentucky. Gooden then found himself in San Juan, Puerto Rico.

I was assigned there as a military police investigator, Gooden said. So I finally got to do my traveling that I have always wanted, just in a different capacity.

Gooden then came close to home.

I was lucky enough to get close to Martinsburg, where I was assigned to Fort Ritchie, Maryland, to the Post Marshals office, Gooden said. There I was a crime prevention officer, a physical security investigator and court liaison officer.

Gooden stayed there until 1981 when he retired.

After staying out 10 years, Gooden decided he wanted back in.

He went to the federal law enforcement academy in Brunswick, Georgia, and was assigned to the Pentagon as a federal police officer and then earned a spot on the protective service detail agency within the U.S. Department of Defense, where he stayed until 2004 when a vehicle accident forced him to retire.

When I was working at the Pentagon, I enjoyed my time on the protective service detail and all aspects really. I met a lot of amazing people and formed great relationships, Gooden said.

Now that Gooden has officially retired, he said he has no plans of slowing down.

Gooden said he plans to take many vacations with his wife and children, but he also has more exciting projects for this upcoming year.

Gooden has a love for gospel music.

According to Gooden, he has recorded two gospel albums already and hopes to record his third, to be released next fall.

I have always had a passion for writing and performing gospel music, Gooden said. I am currently recording for my third album and I am happy I finally have the time to really pursue my music.

Gooden said he is also working on writing a book about his life.

The book will be called God and Country,' Gooden said. I hope to have that out within the next year or two.

Looking back, Gooden remembers his military service fondly.

To me, I have had a great career and I am grateful for the career that I have had, Gooden said. I am not saying all of it was easy, but I truly gave my life to this, I gave the federal government 33 and a half great years and I just cant wait for my next adventure.

Local veteran shares colorful past - Martinsburg Journal

Would you spend a rupee if it saved you Rs 677? Eagerly, perhaps. The US Department of Defense has been saving billions of dollars for 30 years by continuing to use 'expired' medicines in its stock after testing them. Last year, the tests--part of its Shelf Life Extension Program--cost $3.1 million and saved $2.1 billion. Are drugs safe to use past their 'expiry' date? If they are, why do they come printed with expiry dates only 2-3 years from the date of manufacture? A recent article on ProPublica 'That Drug Expiration Date May Be More Myth Than Fact' shows why drug companies ought to revise their expiry schedules.

When Lee Cantrell, a toxicologist who helps run the California Poison Control System, and Roy Gerona, a University of California, San Francisco researcher who specialises in analysing chemicals, started testing leftover stocks of pills from the 1960s, they were surprised to find that "a dozen of the 14 compounds were still as potent as they were when they were manufactured, some at almost 100% of their labeled concentrations."

Have we been 'expiring' perfectly good drugs? - Times of India

July 24, 2017 07:30 ET | Source: Mandalay Resources Corporation

TORONTO, July 24, 2017 (GLOBE NEWSWIRE) -- Mandalay Resources Corporation ("Mandalay" or the "Company") (TSX:MND) is pleased to provide exploration updates for the first half of 2017 for two of its producing properties, Bjrkdal (Sweden) and Costerfield (Australia), and its Challacollo (Chile) development project.

This press release refers to tables and figures. Accompanying tables can be found at the end of this press release, whereas the figures accompanying this release can be found in an exploration presentation posted on the Companys website that can be accessed at:

http://www.mandalayresources.com/investor-presentations/#Technical_Presentations

Dr. Mark Sander, President and CEO of Mandalay, commented, In the first half of 2017, our exploration programs yielded excellent results, which clearly demonstrate the potential for significant near-term and long-term Mineral Reserve additions at both Bjrkdal and Costerfield.

At Bjrkdal, extensional drilling to the northeast and north of the mine demonstrated that the gold mineralized system extends several hundred metres beyond the current mine in those directions and is not yet closed off. As a result, we have demonstrated the potential to increase Mineral Reserves at Lake Zone underground and West Pit at surface. We have also made significant progress in understanding the distribution and characteristics of high-grade skarn mineralization that occurs both in the open pit and underground mines. Follow-up drilling is planned.

At Costerfield, drilling has improved the outlook for mine life extensions at different scales. At Brunswick, new holes have delivered high-grade, deep intersections that are expected to make a positive impact on the updated Mineral Resource and Reserve model anticipated in the fourth quarter. As previously reported, we anticipate the new model will significantly extend mine life based on our expectation that Brunswick will prove to be economic. As well, the potential next major new mineralized shoot after Brunswick has begun to emerge in our new drilling below the historic workings on the main Costerfield lode. These intercepts contain extraordinary gold and antimony grades scattered along a 400 metre strike length and 100 metre vertical interval. New intercepts along N-lode have also identified new splays which, as we follow them up, have the potential for incrementally adding Reserves near current underground infrastructure.

Dr. Sander concluded, Lastly, at Challacollo, we reached a major milestone with the discovery of sufficient water to support an eventual operation. Activities to permit and complete a production well, followed by transfer of existing water rights to the new location are underway. We now have the option to launch a project to optimize previously estimated capital and operating costs for a mine and plant at Challacollo.

Bjrkdal Exploration

Significant Exploration Results (Tables 1 through 4; Figures 1 through 5)

Underground Exploration

In the first half of 2017, underground diamond drilling at Bjrkdal extended the north-eastern limit of the Bjrkdal vein-system and infilled discrete areas. Intercepts from the extensional drilling demonstrate that gold mineralization extends along-strike from the defined resource for at least 200-300 metres (Figure 2 and Table 2) and mineralization remains open to the north and east. Infill drilling also increased confidence and delivered some high-grade intercepts in areas closer to the current limits of the mine (Figure 3 and Table 3).

Open Pit Exploration

Near-mine surface drilling with both core and Reverse Circulation methods during the first half of 2017 focused on extending gold mineralization in the north-western portions of the West Pit (Figure 4). This drilling intercepted many new mineralized intervals in the northern wall of the West Pit (Table 4). Results from this extensional drilling demonstrate that the mineralized vein-system in this area of the deposit extends from the current limits of the West Pit to at least 150 m further to the north. These veins are interpreted to correlate with the same vein-system mined from the underground mine, located to the east of this area. Therefore, the Bjrkdal vein-system remains open to the west and north-west of the current mine footprint, presenting high-calibre extensional targets for future exploration programs at Bjrkdal.

In addition to successful extensional drilling of the Bjrkdal vein-system, significant gold intercepts were also obtained from non-veined, mineralized carbonate lenses belonging to the host-stratigraphy (the Bjrkdal marble unit). These mineralized carbonate lenses are strongly altered, containing abundant amphiboles (predominately actinolite), silica and chlorite with accessory pyrite, pyrrhotite and pyroxenes. This metasomatic assemblage suggests skarn-like depositional mechanisms, and represents an exciting new deposit-type both within and peripheral to the footprint of the current Bjrkdal mine.

Three gold-bearing, skarn-like bodies have been defined though drilling over the past six months; two in the vicinity of the underground mine and a single in the open pit mine (Figure 5). The skarnified carbonate lenses are shallow dipping, narrow, plunging bodies that are located above and adjacent to the Bjrkdal vein-system. Intercepts of this skarn-hosted gold-mineralization include:

These results suggest that this style of mineralization presents the possibility of bulk-minable tonnages of potentially much higher gold-concentrations than the more typical Bjrkdal vein systems. Within the month of June, a 1,176 tonne parcel of the recently exposed West Pit skarn ore was crushed and milled with results indicating a back-calculated head-grade of 4.30 g/t Au. The recent intercepts of all significant gold-bearing skarn intercepts will be followed up as priority targets in the remainder of 2017 and 2018 exploration programs, while regional exploration models and programs will be refined to incorporate further targeting of near-surface, high-grade gold skarn and skarn-like mineralized systems in the larger Bjrkdal area.

Bjrkdal Drilling, Sampling and Assaying

During the period from January 1, 2017 to June 30, 2017, a total of 13,640 metres of exploration drilling was completed in 66 drill holes. Drilling included 23 surface core and RC holes totalling 3,451 m and 43 underground core holes totalling 10,189 m. All drill-hole collars are surveyed, and downhole surveys are completed in order to record hole azimuth and dip variations.

All surface and underground exploration drilling has been conducted by third party contractors, with a mix of core and reverse circulation drilling using WL66, NQ2, HQ and 5 RC sized drilling equipment (producing 50 mm, 50.5 mm and 63.5 mm diameter core respectively).

Core and RC samples are logged by Mandalay geologists on-site. Assaying of Bjrkdal samples was completed at CRS Minlab Oy (CRS) in Kempele, Finland and ALS in Pite, Sweden. Whole core samples (WL66 and NQ2 size) were sent directly to the independent laboratories for sample preparation and assaying, while HQ diameter core was half-sawn at the laboratories off-site before sample preparation. Assaying was conducted utilizing the Pal1000 (CRS) and LeachWELL (ALS) cyanide leaching processes. Mandalays rigorous QA/QC program includes the use of standard reference samples, blanks, duplicates, repeats, and internal laboratory quality assurance procedures. More details on the drilling, logging, sampling, and assaying procedures are contained in the Technical Report Mandalay Resources Corporation Technical Report on the Bjrkdal Gold Mine, Sweden filed on SEDAR (www.sedar.com) on January 27, 2017.

Costerfield Exploration

Significant Exploration Results (Tables 5 through 8; Figures 6 through 12)

Brunswick Following structural analysis of Brunswick mineralization, the Company conducted infill drilling within the Penguin to Kiwi (PK) panel of the Brunswick lode (Table 6 and Figure 7). Further confidence of grade continuity was gained through this drilling, with high-grade intercepts including 24.4 g/t Au and 6.1% Sb over a vein width of 2.01 m in BD278W2.

These results will be reflected in a resource update expected in the fourth quarter of 2017. This drilling is expected to result in an increase in Indicated Mineral Resource of the Brunswick lode.

Further drilling was undertaken with the purpose of extending Brunswick below the Kiwi Fault and to the south. Both drilling campaigns intercepted antimony and gold mineralization along the Brunswick corridor. Mineralization has now been identified approximately 280 m below historic workings and approximately 100 m below the current Inferred Mineral Resource. Below the historic B3 pit, the Brunswick line of mineralization has been identified at a depth of 225 m below surface and over a strike length of 300 m (Figure 7). Highlights of this extension drilling are:

Future exploration efforts are expected to focus on extending the current Mineral Resource below the Kiwi fault and into Brunswick South, pending economic analysis.

Costerfield

A target testing campaign investigating the continuation of mineralization underneath the historic Costerfield mine workings is currently underway. The early stages of this campaign have shown great success with mineralization confirmed over a strike length of approximately 500 m and to a depth of approximately 150 m vertically below the current workings (Figure 8). The highlight of the program during the first half of 2017 is the deepest northern intercept, which contained 59.8 g/t Au and 3.2% Sb over a true vein width of 0.56 m in BC006w1 (Table 7).

N Lode Upper

Structural analysis of the mineralized corridor known as N Lode has led to the recognition of a previously untested prospective zone near to surface. The first drill hole to test this area has confirmed the presence of an up-dip continuity to the enriched northern portion of N Lode. The proximity of this mineralization to established underground development makes this find an important focus for near future delineation drilling (Table 8 and Figure 9).

Alison South

Testing of the upper portion of mineralization over the Cuffley Deposit has returned high-grade gold results within two veins in an offset, up-dip continuation of the Cuffley Deposit named Alison South. The highlight of this drilling was an intercept containing 71.1 g/t Au and 0.5% Sb over a true vein width of 0.35 m in AD168 (Table 8 and Figure 10).

K Lode

A high-grade portion of K Lode was discovered through the opportunistic drilling program (Table 8 and Figure 11). This vein has already been accessed through mining on an intersecting portion of N Lode which makes this a potential low-cost mining source in the near future.

Augusta East

A drilling campaign investigating the possibility of an eastern repetition of the Augusta and Cuffley line of mineralization is currently underway. Gold has been located within a near-surface, sub-vertical vein set in the first hole to be drilled on this target (Figure 12). Although the grade of these intercepts are not potentially economic, they are characteristic of the periphery of orebodies in the district. Follow-up drilling is planned.

Costerfield Drilling, Sampling, and Assaying

During the first half of 2017, Mandalay drilled 18,489 m of diamond core at its Costerfield gold-antimony mine (Table 5). 5,520 m was dedicated to increasing immediate mine life through infill and extension of the Brunswick resource and through opportunistic drilling projects on K Lode, N Lode and Alison South. 12,969 m was devoted to regional exploration, with the drill testing of the Costerfield Mine extension, Augusta East and Brunswick line of lode extension. In addition, the Company completed 1,652 m of on-vein operating development and associated sampling of N Lode, Cuffley Lode, New Vein, Bob lode and associated splays.

Drill core was logged and sampled by Costerfield geologists, who also mapped and sampled the development advances. All samples were sent to Onsite Laboratory in Bendigo, Victoria, Australia for sample preparation and assay. Site geological and metallurgical personnel have implemented a QA/QC process that includes the regular submission of standard reference materials and blanks with drill and face samples submitted for assay. Standard reference materials have been certified by Geostats Pty Ltd. (see Technical Report entitled Costerfield Operation, Victoria, Australia NI 43-101 Report, filed on SEDAR (www.sedar.com) March 31, 2017, which contains a complete description of drilling, sampling, and assaying procedures).

Challacollo Exploration

Four holes were drilled at Challocollo during the first half of 2017 to explore for water, a critical requirement for further project development. A total of 416.5 metres was drilled, with all four holes encountering promising quantities of water. Drill hole locations are provided in Figure 13, with pump test results in Table 9.

Earlier this month, professor Vanessa Grubbs, M.D. visited Seattle, Wash., on the promotional tour for her new book, Hundreds of Interlaced Fingers: A Kidney Doctors Search for the Perfect Match. Grubbs details the romance with her now-husband, Robert, and his life-threatening battle with kidney failure. The book uses their courtship, they are both Black, to illustrate how racial bias prohibits Black people from getting equal access to life-saving organ transplants.

During the question-and-answer session, the doctor was askedto relate Interlaced Fingers to previous scholarship on medical racism such as the work of Harriet A. Washington and Rebecca Skloot, who both documented centuries of deliberate exploitation of Black bodies.

Gingerly, Grubbs told the mostly white onlookers that witnessing her husbands ordeal radically shifted her understanding of how Black patients experience health care. She referenced her 2007 report, Good For The Harvest, Bad For The Planting which provides a systemic explanation for why Blacks, like Robert, who are one in three of the candidates awaiting a kidney transplant, receive only one in five of donated kidneys. She contrasted this to whites, who represent a third of the kidney transplant waiting list, but receive every other donated kidney. White patients also enjoy half the wait time of Black patients in need of a transplant.

Statistics like this in the organ transplant industry bring to light the historic and current racism Blacks face in receiving equal medical treatment in America.

Earlier this year, Oprah Winfrey was the executive producer and star of the HBO drama, The Immortal Life of Henrietta Lacks. The film, based on the book of the same title, is Skloots 2010 bestseller, which explains how white health officials at Marylands Johns Hopkins University stole tissue samples from a Black cancer patient, Lacks, and used her genetic material to make countless advances in medical science.

Providing context for the exploitation of Lacks, Skloot incorporates the history of the white-dominated medical industrys relationship to Black citizens. This includes exposing celebrated scientists like French surgeon and Nobel Prize winner Alexis Carrel, who pioneered early 20th-century ideas on transplanting organs. Skloot writes that Carrel praised Hitler and was a eugenicist: organ transplantation and life extension were ways to preserve what he saw as the superior white race, which he believed was being polluted by less intelligent and inferior stock, namely the poor, uneducated and nonwhite.

Washingtons 2006 masterpiece, Medical Apartheid: The Dark History of Medical Experimentation on Black Americans from Colonial Times to the Present, reveals that racist health professionals like Carrel saturated the U.S. medical industry at one point in history and, to an extent, still do to this day.

In fact, Washington begins with a conversation between herself and a nephrologist, a kidney doctor. When Washington struggled to accept the history and scope of medical abuse against Black people, her colleague looked at her as if she were not too bright and minced no words. Girl, Black people dont get organs; they give organs.

The remainder of Washingtons work unearths how, before and after death, Black people have had organs and other body parts stolen by the white-dominated medical industry. After describing the lucrative industry and longstanding practice of harvesting Black corpses for medical research, she pivots to the organ transplant enterprise. Washington writes, The troubling disproportionate prevalence of Black body parts such as organs, corneas and other tissues is suggestive that Blacks also make up a greatly disproportionate number of the entire bodies that are used in research, research that infrequently benefits Black people like Henrietta Lacks.

In Seattle, Grubbs attributed these disparities to conscious and unconscious bias that require policy changes and training to help health care professionals practice medicine in a socially just manner. This analysis may, however, fall short of curing the bias of medical professionals and the industry itself.

Historian Daina Ramey Berrys 2017 gem, The Price for Their Pound of Flesh: The Value of the Enslaved from Womb to Grave in the Building of a Nation, makes whites willful consumption of Black bodies a central theme and explains how anti-Blackness and the theft of Black organs became a normalized part of our vocabulary.

Berry writes that in 1763, an African-American male became one of the first recorded cases of a dissection in the colonial territory. This marked the beginning of medical education, particularly the dissection of the dead. It also spurred the clandestine business of sending bodies and body parts to physicians and colleges, creating a traffic in human remains that still exists today in the form of an underground organ trade.

Sugarcoating centuries of white pathology masquerading as medical science maintains racism and is a central theme of John Hobermans 2012 book, Black and Blue: The Origins and Consequences of Medical Racism. He too resists the pattern of ignoring or downplaying centuries of racists wearing nurses caps and stethoscopes. Hoberman writes that many recoil at the charge that Blacks suffer disproportionate health problems because racism taints American medicine. Doctors and nurses are among the least likely candidates upon whom to pin the label of bigotry. Because of generations of racist doctors and nurses, Hoberman writes, Mainstream medicine devised racial interpretations that have been applied to every organ system of the human body.

Tellingly, near the end of her Seattle visit, Grubbs admitted that honestly addressing these issues does get hard, and that she often takes flak for illuminating how the medical industry fails Black patients. In a monumental display of courage and love, Grubbs donated a kidney to save then-boyfriend Robert. The two celebrated the 12-year anniversary of the surgery this past April and will enjoy a dozen years married next month. The bravery that helped Grubbss share a life-saving organ must also inspire us discuss and call out racism as the primary obstacle to Black health and prosperity.

Doctor Began to Understand the Role of Racism In Organ Transplants After She Donated a Kidney to Then Boyfriend - Atlanta Black Star

John Wall electedto continue his all-star career with the Washington Wizards, agreeing Friday night to a four-year deal with a player option in the fourth year. The designated player veteran extension will keep him as the teams cornerstone and pay him $170 million.

Wall, the 26-year-old point guard who has played all seven seasons with the Wizards, will be tied to Washington for at least the next five years two on his current deal, and three on the extension before he canopt out. By earning all-NBA honors for the first time after a career year in 2016-17 he was third team Wall became eligible to sign the extension that begins in 2019. Through the life of thecontract, Wall will earn 35 percent of the salary cap.

The deal signals Walls long-term commitment to the franchise, as well as his contentmentwith the directionin which the Wizards are heading.

He wouldnt have signed it if he wasnt, a person familiar with Walls thinking told The Washington Post late Friday night.

In a video posted on the Uninterrupted Twitter account,Wall announced his agreementby speaking directly to a handheld recording device.

Yall know I wasnt going nowhere, Wall said intothe camera. Re-signed with the Wizards, man. Signed my extension. You know where I want to be. I love being in D.C. I love the organization. I love my teammates. I love the amazing fans. Just had to think it out with my family and friends. We made a decision. You know where I want to be at.

Im happy Im coming back, Wall continued. Yall know what Im going for. Definitely going to bring yall that championship. Thats my ultimate goal, and I aint going to stop till I get it. Peace. Love.

Though the news broke late Friday night, Wizards majority owner Ted Leonsis made a bold prediction about Walls future Wednesday following the news conference for Otto Porter Jr. and his four-year max deal.

My prediction is John Wall will sign his extension, Leonsis told reporters. He wants to be here, and my goal is to have no drama.

Mission accomplished.

During the Las Vegas Summer league, Leonsis and team President Ernie Grunfeld met with Rich Paul, Walls agent, to discuss a myriad of topics. The extension, naturally, topped the list. Though Wall could have signed the extension at the start of free agency July 1, he waited. Instead of simply signing, Wall and his representatives wanted to structure the deal in ways that bettered his current contract.

For instance, when Wall signed a rookie extension in July 2013, he did not have a player option. Now, not only does Wall get his out but he also has a 15-percent trade kicker in new extension.

Throughoutthe contract discussions, drama was absent as Wall consistently said he wanted to remain with the Wizards.

Im just chillin. Just trying to figure out to negotiate it and manipulate it the way you want it to be, Wall said, updating reporters on the status of the extension July 10. Everybody know where I want to play and where I want to be. Everybody took it the wrong way I wanted to wait. Its a big decision. I love D.C.

Everything I do, I do it for the city of D.C. I do so much in the community. If it wasnt for the love of that, I wouldnt do it.

Last season, Wall averaged 23.1 points, 10.7 assists and 4.2 rebounds while leading the Wizards (49-33) to Game 7 of the Eastern Conference semifinals. Wallset the franchise career recordfor assists (4,610) and steals(870) and became the first player in league history to average at least 20 points, 10 assists, four rebounds, two steals and 0.5 blocks.

Also during the playoffs, Wall became only the eighth player in NBA historyto average at least 25 points and 10 assists, according to statistics from Basketball-Reference.com. Other players on that list include Hall of Fame point guards Magic Johnson, John Stockton, Isiah Thomas and Oscar Robertson.

Wall joined the Golden State Warriors Stephen Curry and the Houston Rockets James Harden as the three stars to sign the so-called supermax extension.

You have a splitting headache, but the only medicine you have expired six months ago. Should you take it or toss it out? The jurys still out, but a recent ProPublica investigation found that most medicines still work beyond their marked expiration dates, though it stopped short of recommending that consumers go ahead and take expired drugs. A few drugs they tested did actually expire, but most expired 5.5 years past the listed datesome even worked up to 20 years after the date.

Expiration dates dont strictly mean a products expiration, but rather, are the date at which the FDA and drug companies guarantee the drugs effectivenessthere havent been any cases of people being harmed by taking expired drugs. When determining expiration dates, drug makers test how well drugs degrade under the stress of heat and moisture. The FDA then reviews this data to make sure its accurate, but drug companies dont have to test if drugs work past their expiration dates, which is why a lot of expiration dates are earlier than they should be.

On a larger scale, pharmacies throw away drugs once they reach their expiration dates, even if the drug is rare or expensive. Throwing out drugs that can still technically be used contributes to waste, one of the reasons why health care is so expensive in the U.S.

The FDA has a Shelf Life Extension Program that tests whether certain drugs have expiration dates that could be extended. In 2006, the program extended the shelf life of two-thirds of the medicines they tested, with an average of each drug being extended more than four years past its original expiration date. Extending the expiration dates of drugs has saved billions of dollars for pharmacies and the government, but one concern is that extending expiration dates could reduce profit for drugmakers and cause the prices of drugs to increase.

As for whether you should take the expired aspirin, its not the end of the world if you do. Just dont risk it on drugs that your life depends on, like an Epi-Pen.
