Link Between Extreme Glucose Levels In Diabetic Patients With Heart Failure And Increased Risk Of Death
Compared with patients with moderately controlled glucose levels, diabetic patients who have heart failure and either too high or too low glucose levels may be at increased risk of death, said researchers at Baylor College of Medicine in a report published in the current issue of Journal of the American College of Cardiology.

A New Way The Body Fights Fungal Infection Discovered By Researchers At Case Western Reserve
A team of researchers led by Amy G. Hise, M.D., M.P.H., assistant professor at the Center for Global Health and Diseases, Case Western Reserve University School of Medicine, is the first to discover how the body fights off oral yeast infections caused by the most common human fungal pathogen, Candida.

Opinion Piece Examines If Abortion Access Should Ever Be Restricted
"Just because something is legal -- and should be legal -- does not mean it is always ethical," Frances Kissling, former president of Catholics for Choice, writes in a Salon opinion piece, adding that "sometimes the right thing to say to a woman [seeking abortion] is "I am so sorry, I cannot do what you ask."" According to Kissling, there has "always been a fear in the choice movement that if we deal with "morality," we are going to lose." However, "tough issues come up more frequently than they did in the first years after" Roe v. Wade, and such issues "should make us pause and think hard," Kissling writes, adding, "The thought of putting every woman through the indignity of meeting with an ethics committee, or getting a doctor to sign off on her reasons for abortion, has forced most of us to stick with the principle that women must be allowed to make their own private ethical decisions, without the state getting involved." However, Kissling comments that "we express moral views about every other issue under the sun." She continues, "Expressing our views about controversial issues is how society develops norms and shared values."Kissling adds that if abortion-rights supporters "follow the example of those opposed to abortion and present only one value -- a woman"s right to make this decision -- as the only ethical consideration worth discussing in difficult cases, do we not become as extremist as we say they are?" She continues, "Is there not, in an ethical sense, an important weighing of women"s rights and needs against a respect for life, even the life of nonpersons? Is there a point in pregnancy when our respect for life might outweigh a woman"s right to make this choice?" Kissling asks, "[I]s the fact that we have avoided it part of the reason that polls show that more people are willing to call themselves pro-life than ever before?"According to Kissling she has "come to believe that women"s autonomy does not require that all efforts be made to protect women from pain or from hearing the word "no."" Kissling writes, "I still have a twinge of doubt when I write these words," adding, "For most of my years as an advocate of a woman"s right to decide, I stepped back from this conclusion" and "could not bring myself to say that there are circumstances in which I would force a woman to continue a pregnancy." The piece continues, "What changed for me? ... Mostly, I feared that single value ethics about abortion, on either side of the debate, would result in a coarsening of our respect for both women and for life" (Kissling, Salon, 6/21).

Biological Warfare In Bacteria Offers Hope For New Antibiotics

Scientists are to study a group of proteins that are highly effective at killing bacteria and which could hold the key to developing new types of antibiotics. Researchers from the Universities of York and Leeds have been awarded ÷£3.3m from the Biotechnology and Biological Sciences Research Council (BBSRC) to find out how a family of proteins known as colicins force their way into bacterial cells before destroying them. The team, led by Professor Colin Kleanthous, from the University of York"s Department of Biology, will develop earlier research that suggests colicins use decoys to mimic key parts of the cells" own protein machinery to evade their defences. Professor Kleanthous said: "Colicins are the weapon used in the biological warfare that takes place between competing bacteria. Understanding how this group of proteins work could help scientists develop new drug delivery methods to target the bacteria that cause diseases in people." "It"s as though the colicins are carrying the equivalent of hand grenades which they can deploy without harming themselves," said Professor Sheena Radford of the University of Leeds" Faculty of Biological Sciences. The five year programme of research aims to discover how colicins specifically penetrate Gram-negative bacteria which are protected by two membrane barriers. It will involve collaboration between six groups of scientists from the Departments of Biology and Chemistry at the University of York and the Astbury Centre for Structural and Molecular Biology, Faculty of Biological Sciences, at the University of Leeds.
