Innovative smallpox vaccine research study to be conducted at Case Medical Center

... against smallpox. Smallpox is a contagious and sometimes fatal infectious disease characterized by raised bumps that appear on the face and body of an infected person. There is no specific treatment for smallpox disease, and the only prevention is vaccination. The World Health Organization declared the dis...

Simulations unravel outer membrane transport mechanism

...fore and after activation,” Tajkhorshid said. “And sometimes the labeling agent that they use diffuses into the beta-barrel and labels the inside: You don’t know whether what you have labeled is happening inside or outside.” U. of I. researchers simulated the interaction of part of the inner membrane protein...

Genetic factors are linked to fever following smallpox vaccination

...e virus particles, as in the smallpox vaccine, can sometimes cause reactions that range from fatigue to serious illness. In recent studies testing the safety and potency of stored smallpox vaccine, which uses live vaccinia virus, some individuals developed fevers. The authors of the study, Samuel L. Stan...

Study investigates 'divorce' among Galapagos seabirds

...f the females in this group gambled on a new mate, sometimes one that had never bred before. This is one of the few studies that addresses divorce in successfully breeding bird pairs, Maness said. “This study really predicts that the probability of divorce increases with the birds’ success at breeding and ...

Human genetic 'deserts' are teeming with significant life

...on the genome can carry out a number of different, sometimes simultaneous, functions.” Professor Reymond’s team, in collaboration with other laboratories in Switzerland, the UK, the US and Spain, now intends to carry out the same kind of analysis for two complete human chromosomes. “I will be surprised if ...

Helping chlorine-eating bacteria clean up toxic waste

...chardson explained that in the field "the bacteria sometimes start and then stop. We might improve conditions for the organisms." For example, she said, it has been found that Dehalococcoides needs vitamin B-12, so the vitamin is added to cultures that are injected into cleanup sites. The bacterium also grows ...

Understanding why C. difficile causes disease -- it's hungry

... might help them find a new treatment for what can sometimes be a very difficult disease to treat. "The genes responsible for toxin production only seem to be expressed during periods of nutrient deprivation. This is consistent with the view that most disease-causing bacteria express their pathogenicity whe...

How to look at dinosaur tracks

... the tracks are less than perfectly preserved, and sometimes they can be barely recognizable as tracks at all.? With this in mind, Milàn and Loope sought to describe and categorize different levels of preservation. For example, dinosaur tracks may still exist as true tracks, that is, the original prints left...

In addition, he says, manufacturers and teachers sometimes incorrectly apply the concepts of fluid dynamics to the study of brass instruments, giving improper scientific authority to some teaching statements and product descriptions (4pMU1). In wind instruments, an area of controversy has been whether their...

Herpes infection may be symbiotic, help beat back some bacteria

In addition, less infamous herpes viruses like HHV6 and HHV7 permanently infect most humans without ever producing any significant symptoms. The results have potentially wide-reaching imp...

Decoding protein structures helps illuminate cause of diabetes

...ng target. When it comes to molecules, however, sometimes the motion is exactly what scientists want to see - for example, to understand the pathological protein mis-folding and assembly that seem to underlie a host of human disorders, including diabetes and Alzheimer's disease. Now, chemists at the Un...

Scientists seek useful traits in wild cottons

Hives ferment a yeasty brew, attract beetle pest

... it grew on pollen. Even pollen substitute, a food sometimes provided for bees, did not increase the amounts of IPA produced. "We are not really sure how the yeast gets into the colony," says Tumlinson. "Perhaps one beetle finds and carries the yeast in and it reproduces, or, because the yeast grows on pol...
