Researchers seek to design first treatment for neuroAIDS

...s effect on neuroAIDs. CEP-1347 has already proven capable of reversing the neurotoxic effects of HIV proteins in living cells, according to research published in the July 1, 2006, edition of the Journal of Immunology. "We really don't know yet whether MLK or GSK-3b inhibitors will be superior to other tre...

Smashing the time it takes to repair our bones

...ecent graduate Dr Gwynne Hannay has built a gadget capable of promoting bone cell formation in the laboratory. Dr Hannay said his device replicated the mechanical and electrical stimulants which occurred naturally in the body to repair fractured and broken bones. "This device is about trying to grow bo...

Ocean sampling yields environmental sources of coral symbionts

...gone on to show that the isolated algae are indeed capable of establishing symbioses with new corals. The fin...ect new coral polyps. These isolates are therefore capable of establishing symbioses with corals and thus point to environmental sources of symbionts that may ...

Discovery in the evolution of the immune system absorbing cells

... that B cells in fish as well as in amphibians are capable of strong phagocytosis both in in vivo and in vitr... lower vertebrates (fish and amphibians) are still capable of phagocytis while they are producing antibodies, the B cells of higher vertebrates are no longer c...

NHGRI aims to make DNA sequencing faster, more cost effective

...igators has developed a fully automated instrument capable of sequencing single molecules of DNA on a planar surface. The group is now developing a high-throughput version of this technology for the re-sequencing of whole human genomes. The sequencing strategy involves obtaining short reads (about 25 DNA bas...

Early HIV treatment fails to restore memory T cells

Vaccination with embryonic stem cells prevents lung cancer in mice

...g possibility of developing a prophylactic vaccine capable of preventing the appearance of various types of cancers in humans, especially those with hereditary, chronological or environmental predispositions to neoplastic disease." However, he warned that the work was still in its early stages and that pe...

Researchers develop technologies to devour food pathogens

...ter pattern." Bhunia has shown his technology is capable of recognizing Listeria monocytogenes, a microbial pathogen that is the leading cause of food-borne illness. The pathogen has a high mortality rate-one in five-and kills about 500 people each year. E. coli, which has the second highest mortality rate...

Natural protein stops deadly human brain cancer in mice

...tem cells, unlike all other cells in the body, are capable of forming almost any kind of cell when the right "signals" trigger their development. For their treatment experiment, the researchers relied on a class of proteins, bone morphogenic proteins, that cause neural stem-cell-like clusters to lose thei...

A new approach to growing heart muscle

...eered heart muscle, or BEHM, with organized cells, capable of generating pulsating forces and reacting to stimulation more like real muscle than ever before. The three-dimensional tissue was grown using an innovative technique that is faster than others that have been tried in recent years, but still yiel...

Pheromone from mother's milk may rapidly promote learning in newborn mammals

...earning is efficient from the time of birth and is capable of promoting the learning of successive different odorants presented to newborn pups. Given its ability to promote the learning of new olfactory cues, the mammary pheromone may act as a kind of organizing signal that boosts the brain's ability to...

GlycoFi and Dartmouth report full humanization of yeast glycosylation pathway in Science

...first time, scientists have engineered yeast cells capable of producing a broad repertoire of recombinant therapeutic proteins with fully human sugar structures (glycosylation). These sugar structures ensure a glycoprotein's biological activity and half-life and to date, have necessitated the expression of t...

Scientists find mutations that let bird flu adapt to humans

...ansform a virus that only infects birds to a virus capable of easily recognizing human receptors. Receptors are molecules on the surface of cells that permit the virus to dock with the cell and commandeer it to initiate a cascade of infection. By knowing what genetic changes are required for the virus to eas...

Resistance and genetic sensitivity to sleeping sickness

...genes, the mutations investigated were shown to be capable of inducing in the subject carrying them an increased risk of developing this human trypanosomiasis, or conversely a higher chance of a protector effect (2). The associations brought out between these mutations and the disease necessitate work to ...

Experimental vaccine protects mice against deadly 1918 flu virus

...ccine protected the mice by stimulating antibodies capable of neutralizing the 1918 flu virus. "Who would have imagined five years ago that we'd be able to create a vaccine that protects against one of the deadliest forms of influenza the world has ever seen?" adds Dr. Nabel. "It's because the 1918 flu vir...

PNAS study reveals why organs fail following massive trauma

...nvader at hand. Unfortunately, lymphocytes too are capable of mistakenly destroying human cells. Thus, they have developed quality control mechanisms where they can choose to stop expanding into an army (anergy) or to commit suicide (apoptosis). The PNAS study offers new evidence that an overwhelming wave ...

Bitter taste identifies poisons in foods

... "The findings show that our taste receptors are capable of detecting toxins in the natural setting of the fruit and vegetable plant matrix," said senior author Paul Breslin, a Monell sensory scientist. Glucosinolates act as anti-thyroid compounds. The thyroid converts iodine into thyroid hormones, whic...

Professors to develop hand-held pathogen testing device

...cology, is developing a portable, hand-held device capable of detecting up to 50 microbial threat agents in air, water and food. "This device will give us the ability to measure pathogens in a manner and at a price that really matters for human health," Hashsham said. "If we can screen for all pathogens t...
