Male circumcision overstated as prevention tool against AIDS

...viduals in highly infected countries have multiple contacts with the infected so reducing transmission rates only defers the inevitable. The real question is what can be done with the prostitute community. Outlawing the world’s oldest profession would most likely prove to be ineffective. If the profession ...

...nnected to any other) there are a million possible contacts between any two neurons and consequently an unimaginably large number of possible networks. Each combination can have either an inhibiting or an activating effect on the downstream neuron and, in addition to this, can differ in its intensity and reac...

Tumor-suppressor gene is critical for placenta development

...abnormalities in the placenta, especially where it contacts the uterus. They published that research in the journal Nature. "This was the first evidence that Rb had an important role in the placenta," says Pamela Wenzel, a graduate student in Leone's laboratory and first author of the new paper. For thi...

Targeting tumors the natural way

...n cases of mistaken identity, because if the agent contacts the wrong cell type, it can be easily displaced. The team got the idea to mimic this process from efforts to transplant pig organs into primates. The surfaces of most mammalian and bacterial cells express large amounts of a carbohydrate, called al...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

...d. “If it is misaligned even slightly, that set of contacts cannot occur.? As a consequence of that alignment, to angstrom (a unit of length equal to one hundred millionth of a centimeter) precision, a histidine side chain of the trigger loop rests on the ß phosphate, the chemical constituent that must have ...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

...be used as a treatment for family and other direct contacts of infected individuals. 'Protecting virus' is easy to administer as it targets the same cells as any other flu virus and uses the same method to enter the cell. Laboratory work to date has used a drop of saline containing the protecting virus, squ...

Gene-bender proteins may sway to DNA

...lex kinked or sharply bent, allow for the specific contacts needed for a tight DNA-protein fit. Scientists think DNA is largely passive in this genetic tango. But new findings by Anjum Ansari, associate professor of biophysics at the University of Illinois at Chicago, suggest DNA may not be the wallflower ...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

Hard-wiring the fruit fly's visual system

...hese visual maps consist of millions of nerve cell contacts that need to be wired correctly during development in order for the adult animal to see normally. It is generally thought that the complexity of visual maps, like other brain regions, cannot only be genetically programmed but requires activity by neu...

First direct mechanical communication of mitochondria, cardiomyocyte nucleus shown

...sler, a former Soviet scientist who maintained his contacts with Estonian researchers after moving to Paris, said their latest research "shows that substances increasing the mitochondria can also compress the nuclear organelles, ensuring storage and treatment of genetic information." Taken together, the res...

New insight into machinery of immune cells' 'tentacles'

...ls with a "superantigen," they detected Abi at the contacts between T cells and B cells. Their experiments also revealed that the binding of Abi to Wave was required for Abi to reach the contact point. The researchers' experiments also revealed that the Abi/Wave complex was naturally present in T cells. And ...

Tool developed to silence genes in specific tissues using RNAi

...rmation of adherens junctions, or the cell-to-cell contacts between nurse cells and the germ cells that ultimately become sperm. Using RNAi to silence WT1, therefore, led to the discovery that WT1 is the first transcription factor shown to regulate the formations of these junctions, Wilkinson says. "It is a ...

Pretreating rogue cancer cells with aspirin cripples their resistance to targeted therapy

Molecular research suggest shift needed in how some drugs are created

...complex," Nair said. Steric interactions refer to contacts that result when two protein molecules bind with each other. Bad interactions mean that the proteins cannot line up and connect properly. A tight connection is necessary to trigger an immune response. A mammalian counterpart for Drosophila's Tube mo...

Color perception is not in the eye of the beholder: It's in the brain

... College of Wisconsin, gave several people colored contacts to wear for four hours a day. While wearing the contacts, people tended to eventually feel as if they were not wearing the contacts, just as people who wear colored sunglasses tend to see colors "correctly" after a few minutes with the sunglasses. Th...

MSKCC researchers uncover structure of key protein complex in cells

...in this research is to probe the importance of the contacts observed in our structure with the biochemical activities and effects on the cell itself of disrupting these contacts," Dr. Lima said. He and his colleagues are now studying these interactions in yeast. ...

NYU chemists use computer simulation to enhance understanding of DNA transcription

...ns, screening of linker DNA repulsion allows close contacts and attraction between nucleosomes, allowing the array to fold. As chromatin folding or unfolding prevents or allows the transcriptional machinery's access to the DNA in a chromosome, this computer simulation study helps to understand the mechanism o...
