Researchers devise way to mass-produce embryonic stem cells

...e polymer threads on which the stem cells grow and another chamber that holds fluid, or medium. This medium delivers chemical messengers, called cytokines, to the stem cells. The cytokines essentially tell the stem cells to stay in their undifferentiated state. The difference between growing stem cells in a...

Polymers with copper show promise for implanted sensors

...into the lumen of the blood vessel, where it plays another important role: it inhibits platelet function and prevents platelets from sticking to the surface of the blood vessels." Over the years, Meyerhoff and collaborators have developed nitric oxide-releasing polymers, then coated sensors with the polymer...

50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel

...ons we use to care for our patients' target one or another ion channel." Goldstein's team discovered the typ...O (for small ubiquitin-like modifier protein) onto another protein. The presence of SUMO alters how the second protein functions. Goldstein's team first demon...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

...actor in whether one species of yeast could infect another yeast species. Just as in the case with the preseeded mice fibrils, a particular fibril shape in Saccharomyces cerevisiae yeast allowed prion transmission to Candida albicans yeast. The transmission event led to a new strain of Candida prion fibrils...

Increased risk of osteoporosis associated with gene that one in five people have

...YP1A1 gene exist, and the variants differ from one another by one or more DNA base pairs. "Previous studies showed that some CYP1A1 variants are linked to estrogen-related cancers, such as breast, ovarian or endometrial cancers," says Reina Armamento-Villareal, M.D., assistant professor of medicine in the D...

Light therapy may combat fungal infections, new evidence suggests

...r studies had linked the genes to light-sensing in another distantly related fungal lineage, an indication that the fungal light sensor arose early in evolution and may be shared by many extant fungal species. Other well-studied fungi, such as Saccharomyces cerevisiae, or baker's yeast, have apparently lost ...

Marburg haemorrhagic fever in Angola update

...g those for communications and transportation, are another problem. Yesterday, the WHO office in Uige was informed of a death in another municipality, but was unable to collect the body for safe burial because of poor road conditions. F...

Buying Time Through Hibernation on Demand

... the body prior to transplantation, Roth said. Yet another potential application of oxygen deprivation would include accelerating wound healing in patients, such as diabetics, whose ability to do so is compromised. This could reduce the number of amputations caused by irreparable tissue damage from wounds th...

Researchers make gains in understanding antibiotic resistance

...ises due to a mutation in one site, there is still another binding site that can be targeted. It's like multiple drug therapies for HIV, in which the drugs attack several sites at once. And if the virus mutates to avoid the effects of one drug, it still gets hit by another. However, in the case of these anti...

Silence the gene, save the cell: RNA interference as promising therapy for ALS

... can silence the gene and at the same time produce another normal form of the protein," notes Patrick Aebischer, EPFL President and a co-author of the study. ALS is a progressive neurological disease that attacks the motor neurons controlling muscles. Although its victims retain all their mental faculties, ...

Revolutionary nanotechnology illuminates brain cells at work

...llow proteins behave as if they move away from one another when the sensor recognizes glutamate. Thus, there is more cyan and less yellow light than in the absence of glutamate. The sensors are encoded by genes and genetic ZIP codes can be used to target the sensors to any location in the cell and to its sur...

Genetically Modified Natural Killer Immune Cells Attack, Kill Leukemia Cells

... in order to eliminate residual leukemic cells. In another application, NK cells could be obtained from a patient while in remission and then reinfused after genetic modification if the patient suffers a resurgence of the leukemia. "We look forward to seeing this strategy being added to the management of ch...

Some Brain Cells 'Change Channels' To Fine-tune The Message

Emergence of cancer as major cause of childhood death in developing countries is not being adequately addressed

...of the St. Jude International Outreach Program and another co-author of the editorial. The authors note that one of the most effective strategies is a cooperative process between institutions, called twinning, which is already in place in Central and South America, Africa and Southeast Asia, thanks to the ef...

Same-Sex Mating Discovered in a Toxic Fungus

...w chances to mate. It's been a mystery." In 1996, another group discovered that those alpha isolates could undergo fruiting and produce spores, a process that resembles sexual reproduction. However, researchers thought that the unisexual fruiting occurred strictly through the asexual division of cells into ...

Potential Drug Target For Treating Cocaine Abuse Found

...amount of dopamine that is sent from one neuron to another within the brain reward system. Dopamine signals pleasure and reward by binding to receptors on the receiving neurons, after which it is reabsorbed for later use by a protein that transports it back into the sending neuron. But cocaine blocks the mec...

Biologists discover why 10% of Europeans are safe from HIV

...f the CCR5-delta32 mutation to its protection from another deadly viral disease, acting over a sustained period in bygone historic times. Some scientists have suggested this disease could have been smallpox or even bubonic plague but bubonic plague is a bacterial disease rather than a virus and is not block...

PET/CT can identify new cancer lesions at early stage, allowing for prompt treatment

...nt's primary disease and incidental coexistence of another primary malignant lesion can be missed. "Such newly identified lesions are often of early stage and have a better likelihood of being cured if treated promptly and aggressively," indicated Wahl, the senior author who co-wrote the JNM article, "Detect...
