Researchers Uncover Key Step In Manufacture of Memory Protein

...ug for an electric appliance fits into an electric wall outlet, Dr. Loh said. The golgi apparatus then encases the lipid rafts ?along with proBDNF ?in bubble-like structures known as vesicles. Within these vesicles, proBDNF is converted to mBDNF by other enzymes. The vesicles are then transported to the ...

Supercomputer Dedicated To Bioengineering, Computational Biology Installed

...gation of an electrical impulse thorough the heart wall require us to generate matricies with millions of individual cells, and our ability to solve such problems is limited by the memory available. This new cluster will enable completely new simulations of the heart and other biological systems." Tradit...

Two are better than one

..., that sit antenna-like on the outside of the cell wall and are implicated in certain types of cancer. A team of researchers under Prof. Yosef Yarden, Dean of the Weizmann Institute's Feinberg Graduate School and a professor in the Institute's Biological Regulation Department, had previously found that, u...

Human Eggs Can Develop From Ovarian Surface Cells In Vitro

...losa cells (the layer of small cells that form the wall of the ovarian follicle) may originate from OSE cells and assemble together to form new primary follicles -- the structures that grow and rupture during ovulation to release mature eggs. However, definitive proof that new oocytes may develop in adult...

New insight into autoimmune disease: Bacterial infections promote recognition of self-glycolipids

...teria or even just exposure to pieces of the outer wall of the bacteria results in an increase in "self" GSL synthesis by cells that promote the immune response and subsequent stimulation of autoreactive GSL-specific T cells. "Collectively, these findings suggest that recognition of self by infection is ...

Compound might defeat African sleeping sickness, clinical trial beginning this month

...ey can cross the blood-brain barrier, a biological wall that protects the nervous system naturally but can block beneficial drugs, he said. Work is also progressing rapidly on a new drug for drug-resistant malaria, another major threat in developing countries. The UNC-led Consortium to Develop New Drugs ...

Spiders help scientists discover how muscles relax

...sease is hypertrophic cardiomyopathy, in which the wall of the left ventricle of the heart becomes enlarged, causing sudden death. It is caused by mutations in certain genes that encode several muscle proteins--some of which are related specifically to the myosin that Padron studies. ...

Beyond genes: Lipid helps cell wall protein fold into proper shape

...ggs hatch in the intestine, burrow through the gut wall and travel to muscles, where they form cysticerci. The infection rarely causes symptoms in pigs. Only cysticerci- not eggs- can develop into the adult form, so if you prevent infection in pigs, you can break the life cycle, says team member Charles ...

Bacteria in Household Dust May Trigger Asthma Symptoms

...ratory symptoms. Endotoxins are found in the cell wall of bacteria and are only released when bacteria ruptures or disintegrates. Because bacteria can be found everywhere in the home, the likelihood of their release is high. Once released, endotoxins can cause inflammation of the airways and lead to asth...

Like a mason using cement to build a wall brick by brick, bacteria use enzymes known as glucosyltransferases to build dental plaque piece by piece, quickly forming a gunky fortress that covers the tooth and gives bacteria a safe haven to munch on sugar, thrive, and churn out acid.
