Blind Girl Students to Catwalk in Guwahati Fashion Show

Some of India's top models will sashay down the catwalk alongside eight blind... Himangshu Bora is busy training the eight excited models of the Guwahati Blind School who will have supermodels Nina Manuel and Dippanita Sharma for company ...

New Sleep Gene Discovery Wakes Up Scientists

...t a complete surprise to Forger, who develops math models of the circadian rhythms. Forger's computer models always said that the opposite of the prevailing thinking should be true---that the PERIOD protein sh...

Autoimmune disorders studied in detail by U-M researchers.

...er types of diseases. // Clinical trials on animal models have revealed the capacity of the drug to reduce the potency of a key enzyme, in charge of energy production. 'Many drugs block the function of enzymes, essentially turning them off,' said Gary Glick, who is the Werner E. Bachmann Collegiate Profes...

Natural Approach to Immune Regulation May Help Transplant Patients

...k for many other diseases. He has created animal models in which these inhibitory receptors are expressed on the cell surface. Using the same mixture the body uses – cytokines and growth factors – he also gets the receptors expressed on the surface of human cells in a test tube. He gives HLA-G in both sit...

Mutation in Breast Stem Cells Lead to Breast Cancer

...a Hall Institute researchers were working on mouse models when they found that the breast stem cells do not express receptors for the female hormones oestrogen or progesterone. This characteristic is very similar to those seen in the aggressive basal subtype of breast cancer. It is now a known fact that bre...

Joint Center for Molecular Modeling Instituted by Burnham Institute for Medical Research & UC San Diego

...er in a matter of minutes, but the quality of such models is generally so poor that they are not useful in many applications, such as drug design. We have developed tools that allow us to learn from structures already solved and apply that knowledge to improve predicted structures of new proteins. This fund...

Experiments In Outer Space To Determine single Cell Survival

... Groups of such long-lived cells may also serve as models to investigate how tuberculosis bacteria survive long periods of dormancy within human bodies. En masse, they also may be used to generate signals to repel harmful bacteria from the surfaces of surgical tools like catheters. Finally, the method als...

Meeting To Discuss Issue Of Personal Health Records

...security and honoring individual control, business models for rolling out PHRs, societal issues in promoting the uptake of PHRs, use of PHR systems for the public good, legal challenges, and measurement of the value of the technology. "Children's Hospital Boston, which pioneered development of personally ...

Stem cells help in the understanding of drug-resistant, recurrent tumors

... the first time stem-like cells have been found in models of ovarian cancer and in cells associated with human ovarian cancer." Several recent studies have identified tiny populations of tumor cells that appear to act like stem cells, driving the tumor's ability to grow and spread. If some of these specia...

Students Light Up Despite School Anti-Smoking Programs

...hat school programs incorporating social influence models can affect smoking behavior in the short term,” the reviewers wrote. But when they pooled the results of the social influence interventions, they were not statistically significant. Combined programs used both social competence and influence method...

NHGRI Aims To Sequence Primate Genomes

...n addition, some primates are important biomedical models because of their genetic, physiologic and metabolic similarities with humans. For example, the rhesus macaque is an essential research model for drug development, neuroscience, behavioral biology, reproductive physiology, endocrinology and cardiovasc...

Mouse Model Demonstrates Immune System Reaction In Chlamydia Infection

...ers have mapped out the way immune system in mouse models responds to germs in the genital tract //during the initial stage of Chlamydia trachomatis infection. The study is published in the July 24 early edition online of the Proceedings of the National Academy of Sciences and could prove important in the d...

Knee Osteoarthritis May Be Triggered By Low Levels Of Estrogen

...or other risk factors. "Selected work with animal models provides support for the increased odds of developing OA with lower estradiol concentrations," the authors note. This is one of the few studies that has actually examined hormone concentrations, particularly in relation to new cases of OA, and the fi...

Waxing And Waning Of Dengue Epidemics Attributed To Cross-Immunity

...researchers a framework that can be used to create models that predict dengue outbreaks in both space and ti...s compared the data with results from mathematical models that explore – both independently and collectively – the role factors such as temporary cross-immuni...

Role Of MicroRNAs In Angiogenesis Researched

...ast in Petri dishes yet grow explosively in animal models for the disease. "There are obviously no blood vessels in a petri dish, so the angiogenic properties of the MYC gene are not advantageous," said Michael Dews, senior researcher in the Thomas-Tikhonenko lab. "In the incubator, the cancer cells grow ...

Discovery In "Bubble Boy" Disease Gene Therapy

...emoved bone marrow stem cells from these new mouse models (Arf -/- gamma C -/- ) and inserted gamma C into t... experiment, the St. Jude investigators used mouse models that lacked Arf but had normal gamma C genes and therefore did not have XSCID. The team used this mo...

Abdomen Can Help In Gas Exchange In Lung Failure

...rated in an effort to create a technique in animal models that allows// the abdominal cavity to perform the function of exchanging gases, a function primarily performed by the lungs. This may help lungs recover better in lung failure and also give supplementation to the ventilator, the researchers say in th...

New Studies On Zebrafish Could Aid in Treating Birth Defects

... the mouse and the frog Xenopus laevis as research models for vertebrates (animals with backbones), but zebrafish have an important advantage for studying early development: It is possible for researchers to watch the changes that take place in their embryos from the moment of fertilization. The small fish ...

Study Finds Healthier Women Are Those Who Accept The Way They Look

...eaters do not end up with figures like the fashion models but women could attain their ideal body type, at a lower or higher weights, but at the same time they would all achieve and maintain good health. Tylka and colleagues presented two studies at this week's annual meeting of the American Psychological...

Long-life genes - A new way to combat cancer…

...akes for a quick study of old age. More human-like models will need to be studied to unravel what is really going on say other experts. Biologist Siegfried Hekimi of McGill University in Montreal, who studies C. elegans, warns that the laboratory-engineered worm tumors are very different to naturally occu...
