Scientists analyze chromosomes 2 and 4

...nherited disorders. Chromosome 2 is noteworthy for being the second largest human chromosome, trailing only chromosome 1 in size. It is also home to the gene with the longest known, protein-coding sequence ?a 280,000 base pair gene that codes for a muscle protein, called titin, which is 33,000 amino acids ...

Human Eggs Can Develop From Ovarian Surface Cells In Vitro

...division to become mature human eggs -- capable of being fertilized and developing into an embryo. These in vitro findings support earlier in vivo studies by Bukovsky and colleagues that OSE cells are bipotent; capable of differentiating along two developmental pathways and becoming either egg or granulosa...

Alcohol consumption disrupts breastfeeding hormones

.... Recent surveys indicate that 25% of women report being encouraged by their health professionals to drink alcohol while breastfeeding. But as Mennella points out, "There was no valid scientific evidence to support this claim." To address this research deficit, the current study, reported in the April 200...

'EuroVacc 02' HIV Vaccine Trial Begins

...ntrary to classical vaccine boosters, one strategy being developed for a preventive HIV vaccine comprises two different "antigen transporters" (vectors). A first dose of antigen A in vector X is administered, followed by a booster using the same antigen A in vector Y this time. In this way, immune reaction...

Venom doc tracks down snake bioweapons

...known snake toxin types. Surprisingly, rather than being saliva-modified proteins, 21 of the toxins were shown to have been originally derived from proteins normally expressed in other body tissues, including brain, eye, lung, heart, liver, muscle, mammary gland, ovary, and testis. Only two of the toxins ...

Natural Killers Could Lead to New Hepatitis Treatments

... the evidence we can obtain so far points to CXCR6 being involved in promoting survival of these NKT cells when they get into the environment of the liver, and that's how the cells tend to accumulate there,?said Littman. “Our data don't support a critical role of CXCR6 in crawling behavior of the cells.?/p...

Engineers improve plastic's potential for use in implants by linking it to biological material

...e, and the resistance of the peptide-coated tip to being passed across the surface revealed how well T59 clung to the plastic. "They had a moderately strong interaction, which is useful to know," Schmidt said, referring to the need for a stable attachment between polypyrrole and biological molecules that ...

Researchers test new therapy for advanced melanoma

...cause it is the first time that electroporation is being used to deliver plasmid DNA in a gene therapy study in humans," said Richard Heller, PhD, USF professor of medical microbiology and immunology who helped develop the technology used in the study.

U.N. mulls the protection of Earth's forests

...t's not that the United States isn't interested in being involved," Auer said. "It's that the U.S. is not convinced that a convention is the best way to promote sustainable forest management. There are many environmental conventions in force that do not deliver what they promise. A better alternative is to...
