First human study confirms that immune cells can be a primary cause of bone loss in gum disease

...issues. However, the fact that periodontal disease continues to progress, even though B cells produce a weapon to fight off the bacteria, raised an important and interesting question. To answer this question, Dr. Kawai's group found that RANKL expressed on the T and B cells in the patient's gingival tissues w...

Stanford doctors advance in bid to turn mice stem cells into blood vessels

...lar disease, the need for arterial vascular grafts continues to grow. In 2002, there were 1.5 million medical procedures done that required replacement blood vessels. "This is an exciting, emerging research front," said John Cook, MD, PhD, professor of medicine (cardiovascular medicine). "It has great potenti...

...could prove difficult to reverse as embryo quality continues to improve ?whether in the IVF lab or in the community generally." "Because two implanted embryos have twice the chance of MZ twins than a single implanting embryo the best way of minimising MZ as well as DZ twinning is to transfer one embryo at a t...

Impressive new Impact Factors for BioMed Central's open-access journals

The impact factors, which are calculated by Thomson Scientific (ISI), look at citations in 2005 of articles published in the journals in the p...

Researchers seek to solve mystery of natural HIV control

.... Unless antiviral medications are used, the virus continues to reproduce until it overwhelms the CD4 T helper cells, suppressing the immune response and leading to AIDS. In the early 1990s, it was recognized that a small minority of HIV-positive people remained healthy and did not progress to AIDS despite ma...

Combating anthrax: Results of study published this month as researchers look for a better vaccine

...r. "This type of research, five years after 9/11, continues to be very important to pursue," Gorse said. "We need a better vaccine to help protect people from anthrax infection, whether the vaccine is given before or soon after exposure to anthrax spores." Gorse said the study was able to answer some importa...

"There are differences between mammals and invertebrates, but within a group, from a mouse to an elephant, or plankton to a large fish, we have f...

The molecular post office inside the cell

...ns. The ribosome is anchored at the translocon and continues with protein biosynthesis. Notable is that the ribosome can no longer bind to the translocon as soon as the SRP has bound to the ribosome. The ribosome needs additional support from the SRP receptor, which it transfers from the SRP to the translocon...

Potato blight pathogenicity explained by genome plasticity
