Microbiology senior Patrick Ropp patiently has brewed and parried his way through bottles and bouts for a months.

After taking a food science course last fall which focused on the fermentation and commercial brewing of different types of alcohol with chemical engineering and food science professor Kris Berglund, Ropp decided to improvise his own brew. After purchasing a brewing kit, he added hibiscus leaves to the pale ale for a unique flavor.

He calls it Prix de Fleur, a name he said was derived from four years of fencing humor. In fencing, the term, prise de fer is a defensive action meaning taking the blade.

Yet, despite the aggressive nature of the weapon, Ropp views himself as a patient fencer, allowing his own pace to dictate the match. Its a quality he said the art of brewing beer seems to share.

Ropp said his choices in fencing and brewing are a lot of work on both to come down to basically a really finished, really good looking end product.

2013 EIDA AWARDS: Cori Fata-Hartley
2013 EXCELLENCE IN DIVERSITY AWARDS Friday, February 15, 2013 4:00 pm Cori Fata-Hartley ASSISTANT PROFESSOR Department of Microbiology and Molecular Genetics College of Natural Science Lyman Briggs College Indivual Award: Sustained Effort toward Excellence in Diversity Above and beyond her teaching and research responsibilities, Dr. Cori Fata- Hartley, Assistant Professor of Biology, has dedicated much of her career to promoting academic and workforce diversity in the fields of science, technology, engineering, and mathematics (STEM), disciplines in which women and minorities have long been under-represented. Recognizing that change begins at the administrative level, she co-founded the Lyman Briggs Committee for Inclusivity (LBC Inc.), established to promote and foster an inclusive environment and equal opportunities for all Lyman Briggs students, faculty, and staff through education, research, and service. Noting that some freshmen were ill prepared for the rigors of the existing science and math curriculum, Dr. Fata-Hartley pursued a Creating Inclusive Excellence (CIE) grant to design a new curriculum to increase retention and success of minority students in STEM fields. Through another CIE grant, she collaborated with a small inter-disciplinary faculty team to develop a senior seminar -- Investigating Diversity in Science -- to reinforce the importance of diversifying the STEM workforce. To further support student success, Dr. Fata-Hartley helped a group of Lyman ...

Mutation altering stability of surface molecule in acid enables H5N1 infection of mammals

A single mutation in the H5N1 avian influenza virus that affects the pH at which the hemagglutinin surface protein is activated simultaneously reduces its capacity to infect ducks and enhances its capacity to grow in mice according to research published ahead of print today in the Journal of Virology.

"Knowing the factors and markers that govern the efficient growth of a virus in one host species, tissue, or cell culture versus another is of fundamental importance in viral infectious disease," says Charles J. Russell of St. Jude Children's Research Hospital, Memphis, TN, an author on the study. "It is essential for us to identify influenza viruses that have increased potential to jump species, to help us make decisions to cull animals, or quarantine humans." The same knowledge "will help us identify targets to make new drugs that stop the virus [and] engineer vaccines."

Various influenza viruses are spreading around the globe among wild birds, but fortunately, few gain the ability to jump to humans. However, those that do, and are able to then spread efficiently from person to person, cause global epidemics, such as the infamous pandemic of 1918, which infected one fifth and killed an estimated 2.7 percent of the world's population. Occasionally, one of these viruses is exceptionally lethal. For example, H5N1 has killed more than half of the humans it has infected. The specter of such a virus becoming easily transmissible among humans truly frightens public health officials. But understanding the mechanisms of transmission could help microbiologists find ways to mitigate major epidemics.

When influenza viruses infect birds, the hemagglutinin surface protein of the virus is activated by acid in the entry pathway inside the host cell, enabling it to invade that cell. In earlier work, Russell and collaborators showed that a mutant version of the influenza H5N1 virus called K58I that resists acid activation, loses its capacity to infect ducks. Noting that the upper airways of mammals are more acidic than infected tissues of birds, they hypothesized, correctly, that a mutation rendering the hemagglutinin protein resistant to acid might render the virus more infective in mammals.

In this study the investigators found that K58I grows 100-fold better than the wild-type in the nasal cavities of mice, and is 50 percent more lethal. Conversely, the mutant K58I virus failed completely to kill ducks the investigators infected, while the wild-type killed 66 percent of ducks, says Russell. "A single mutation that eliminates H5N1 growth in ducks simultaneously enhances the capacity of H5N1 to grow in mice. We conclude that enhanced resistance to acid inactivation helps adapt H5N1 influenza virus from an avian to a mammalian host."

"These data contribute new information about viral determinants of influenza virus virulence and provide additional evidence to support the idea that H5N1 influenza virus pathogenesis in birds and mammals is linked to the pH of [hemagglutinin] activation in an opposing fashion," Terence S. Dermody of Vanderbilt University et al. write in an editorial in the journal accompanying the paper. "A higher pH optimum of [hemagglutinin] activation favors virulence in birds, whereas a lower pH optimum favors virulence in mammals."

Based on this and another study, "surveillance should include phenotypic assessment of the [hemagglutinin] activation pH in addition to sequence analysis," Dermody writes.

The journal carefully considered whether to publish the paper, because it raised issues of "dual use research of concern" (DURC), writes Dermody. DURC is defined as "Life sciences research that, based on current understanding, can be reasonably anticipated to provide knowledge, information, products, or technologies that could be directly misapplied to pose a significant threat with broad potential consequences to public health and safety, agricultural crops and other plants, animals, the environment, materiel, or national security," according to a US government policy document. However, both the National Institute of Allergy and Infectious Diseases and the St. Jude Institutional Biosafety Committee concluded that the study failed to meet the definition of DURC. Clinching the case, "the addition of the key mutation in the Russell paper to other previously reported mutations would not result in an even more virulent H5N1 influenza virus," says Dermody.

City prof. bags C.V. Raman prize

Posted on by

Every year, February 28 is celebrated as National Science Day to commemorate renowned physicist C.V. Ramans discovery of what is known as the Raman effect.

But it has taken over 20 years for a scientist from the State to receive the award constituted under his name.

S. Rajarajan, 58, a professor of microbiology at Presidency College has been awarded the Dr. Sir C. V. Raman birth centenary gold medal this year. Dr. Rajarajan, who hails from Cuddalore is an alumnus of Presidency College and the University of Madras, and holds a Ph.D in medical microbiology.

It is believed that Prof. Raman booked his tickets much before the announcement of the award. He was confident of getting the award because he believed in his research. That is very inspiring for me, said Prof. Rajaram, who was given the responsibility of setting up a microbiology lab in Presidency College in the late nineties.

It was difficult because we had to start everything from scratch. Getting experts in this field is a big challenge, he explains. Presidency College now is one of very few colleges here that offers postgraduate and Ph.D programmes in microbiology.

Prof. Rajaran is also the principal coordinator of the national-level programme to develop an antiviral drug for closely-related viral diseases such as chicken pox and herpes. However, the principal focus of Prof. Rajarajans research has been mosquito-borne diseases such dengue and chikungunya which are causing an increasing number of deaths of late.

We have collaborated with other institutes in Kanpur and Jammu, to collect blood samples. Everything will be processed here, the scientist said.

He also said there is an increasing interest among students in research in pure sciences, but many are also drawn to engineering.

Knowledge of pure sciences is important to enjoy engineering, which is application-oriented. I tell them to be patient because research takes time to bear fruit. Not many engineers are well known, but Sir C.V. Raman, a scientist, is respected everywhere, he said.
