Dec. 30, 2013 A preliminary study led by a UPV/EHU-University of the Basque Country researcher in collaboration with the Autonomous University of Nayarit, in Mexico, indicates that weekend alcohol consumption may affect DNA.

A study begun in Mexico with the collaboration of university students analysed the effect of weekend alcohol consumption on the lipids comprising cell membrane and its genetic material, i.e. DNA. Until now, the damage to the packaging of nuclear material in the early stages of alcohol abuse has never been documented, perhaps because most of the studies are done at later stages with people who have been consuming alcohol in an addictive way for many years. The results have been published in the journal Alcohol.

The harmful consumption of alcoholic beverages is a global problem and constitutes a significant health, social and economic problem. According to World Health Organisation data, alcohol is responsible for 2.5 million deaths a year worldwide and youngsters between the ages of 19 and 25 account for 320,000 of them; it causes harm that goes beyond the drinker's physical and mental health. The effects of alcohol abuse have been mostly studied in people who have been consuming alcohol for a long time and who therefore display symptoms ranging from liver damage to various types of cancer, depression and disorders of the nervous system. That is why this study is pioneering because it deals with the effect of alcohol on young, healthy people.

The idea of studying the oxidative effect of weekend alcohol consumption came about when the researcher Adela Rendn was lecturing in Clinical Biochemistry at the National Polytechnic Institute in Mexico. Many of the students turning up for class first thing on Monday morning displayed a lack of attention and general malaise due to having drunk alcohol over the weekend. The researcher suggested to them that they should study the effects on their bodies of the weekend consumption that the students regarded as harmless. The students got involved in the project in which Jess Velzquez (Autonomous University of Nayarit, Mexico) also participated, and after completing the necessary administrative requirements and enlisting the help of various experts in surveys and analysis, the aim of the study was specified: oxidative damage caused by the consumption of alcohol beverages in young people.

The students were divided into two groups: the control group made up of the students who did not drink alcohol and the study group of those who drank at weekends. To make sure that they were healthy individuals without any other diseases or addiction that could alter the results of the study, they underwent blood tests. The age of the students ranged between 18 and 23 and the average consumption of alcohol was 118 g, a litre and a half of beer, for example. The activity of the alcohol enzyme dehydrogenase, responsible for metabolising ethanol into acetaldehyde, acetoacetate and acetone was measured. Oxidative damage is evaluated by a TBARS biochemical test (types that react to barbituric acid), and reflects the lipid peroxidation that affects the membrane due to the impact not only of the ethanol in the blood but also of the acetaldehyde produced by the action of the enzyme on the ethanol. Therefore, there are at least two means by which free radicals are formed and which can damage cell membrane integrity.

Although the researchers expected to find oxidative damage, they were surprised by the result, as Adela Rendn explained. "We saw that the ones who drank sustained twice as much oxidative damage compared with the group that did not consume alcohol," and they decided to continue with a test to assess whether the DNA was also affected: the comet test. They extracted the nucleus of the lymphocytic cells in the blood and subjected it to electrophoresis. "The interesting thing is that if the chromatin is not properly compacted, if the DNA has been damaged, it leaves a halo in the electrophoresis," which is called, "the comet tail." And in actual fact the chromatin of the exposed group left a small halo, greater than that of the control group. To be precise, the results revealed damage in 8% of the cells in the control group and 44% in the exposed group. Therefore, the exposed group had 5.3 times more damaged cells.

To be able to confirm the existence of considerable damage to the DNA, the comet tail must exceed 20 nm, and that was not the case. "Fortunately," the researcher pointed out, "but the fact is, there should not have been any damage at all because they had not been consuming alcohol for very long, they had not been exposed in a chronic way." The means by which alcohol manages to alter DNA is not yet known. The next step would be as follows: to study the re-packaging of the chromatin and the behaviour of complex mechanisms like the histones in these individuals. "When we talk about youth alcohol abuse, we are referring to youngsters who drink alcohol without having become addicted. Addiction involves a more complex issue socially and psychologically speaking. This is social alcohol abuse," said the researcher, "but which causes damage in the long term and you have to be aware of that."

Alcohol leaves its mark on youngsters' DNA

BEIRUT Lebanese authorities have arrested a man suspected of being the leader of an al-Qaida-linked group and sent DNA samples to Saudi Arabia to crosscheck against family members to confirm his identity, officials said Thursday.

A Lebanese security official close to the investigation said the man, who was arrested Monday, is believed to be Majid al-Majid, a Saudi citizen and the commander of the Abdullah Azzam Brigades. The Sunni extremist group has claimed responsibility for several bombings, most recently the attack on the Iranian Embassy in Beirut that killed at least 23 people.

DNA samples taken from the suspect have been sent to Saudi Arabia for comparison with samples from al-Majid's relatives, the official said on condition of anonymity because he wasn't authorized to brief the media. He said results were expected later Thursday.

The Saudi ambassador to Lebanon was quoted in the kingdom's state-owned Al-Riyadh newspaper on Thursday as saying Lebanese authorities had informed him that they had arrested Majid al-Majid.

The ambassador, Ali Saeed Asiri, said Saudi officials are awaiting the DNA results to be 100 percent sure of the suspect's identity. If the tests confirm the man in custody is indeed al-Majid, then the kingdom would like him to repatriated to Saudi Arabia, Asiri said.

The ambassador also said that al-Majid's health was believed to be poor and that is why confirming his identity has taken so long. He did not elaborate.

The Saudi Embassy in Lebanon confirmed the remarks to Al-Riyadh.

Saudi Interior Ministry spokesman Mansour al-Turki said in a statement Thursday that al-Majid is among the kingdom's 85 most wanted al-Qaida suspects.

Saudi security officials told The Associated Press that al-Majid is number 70 on the list. The officials spoke on condition of anonymity because they were not authorized to speak to media.

A match from a DNA sample left on a piece of latex led police to the 66-year-old suspect who pleaded not guilty this week to killing a 62-year-old man in Koreatown in March, a prosecutor said Tuesday.

Responding to complaints about a foul smell in mid-March, Los Angeles Police found Cornelius Rich dead in his Koreatown apartment at 527 S. Kingsley Drive. He had died about 10 days earlier as a result of blunt-force trauma, police later said.

A small piece of latex, that police believe to be from a glove, was found torn along the zipper of Richs pants, Los Angeles County Deputy District Atty. John Gilligan said. DNA pulled off the glove eventually matched a sample in the national law enforcement DNA database that belonged to Roy Lee Adams, prosecutors said.

Adams had previous convictions for drugs, trying to escape from prison and carrying an unregistered, loaded gun, according to prosecutors.

Although Adams and Rich seemed to be friends, the motive for the killing appears to be robbery, Los Angeles Police Lt. John Radtke said. The latex, he said, was likely left behind as Rich allegedly searched for cash.

HOMICIDE REPORT: Tracking killings in Los Angeles County

Adams was arrested last week at a downtown building housing people suffering from mental illness or chronic homelessness.

Adams pleaded not guilty to murder with an enhancement of using a blunt object. If convicted, he faces up to 25 years to life in prison.

Adams was being held in lieu of $1-million bail and is due back in court Jan. 10.

The case is one of three homicides reported this year in Koreatown, a neighborhood that saw a dozen or more homicides a year as recently as 2008. Of this year's cases, one involved a victim being shot on a sidewalk and remains unsolved. A suspect has been charged in the other, a robbery-homicide.

Dec. 30, 2013 DNA barcoding is used as an effective tool for both the identification of known species and the discovery of new ones. The core idea of DNA barcoding is based on the fact that just a small portion of a single gene already can show that there is less variation between the individuals of one species than between those of several species.

Thus, when comparing two barcode sequences one can establish whether these belong to one single species (viz. when the amount of variation falls within the 'normal' range of the taxon under consideration and below a certain threshold level) or possibly to two species (when the amount exceeds this level).

A recent study in the open access journal ZooKeys sequenced 388 individuals of 147 bird species from The Netherlands. 95% of these species were represented by a unique barcode, but with six species of gulls and skuas having at least one shared barcode. This is best explained by these species representing recent radiations with ongoing hybridization. In contrast, one species, the Western Lesser Whitethroat showed deep divergences between individuals, suggesting that they possibly represent two distinct taxa, the Western and the Northeastern Lesser Whitethroat.

Our study adds to a growing body of DNA barcodes that have become available for birds, and shows that a DNA barcoding approach enables to identify known Dutch bird species with a very high resolution. In addition, some species were flagged up for further detailed taxonomic investigation, illustrating that even in ornithologically well-known areas such as the Netherlands, more is to be learned about the birds that are present.

"The barcoding approach is particularly useful in musea," comments Dr. Aliabadian, Ferdowsi University of Mashhad, Iran, "This illustrates the value of DNA tissue vouchers 'ready for use' from the bird collection of the Naturalis Biodiversity Center in Leiden."
