Not all acne bacteria trigger pimples: Study

The bacteria that cause acne live on everyone's skin, yet one in five people is lucky enough to develop only an occasional pimple over a lifetime.

Researchers develop new method to study complex molecular workings of Anopheles albimanus

Researchers at the Johns Hopkins Malaria Research Institute have developed a new method for studying the complex molecular workings of Anopheles albimanus, an important but less studied spreader of human malaria.

Researchers develop new genetically altered mice that model earliest stages of Alzheimer's

Researchers at the University of Florida and The Johns Hopkins University have developed a line of genetically altered mice that model the earliest stages of Alzheimer's disease. This model may help scientists identify new therapies to provide relief to patients who are beginning to experience symptoms.

UMDNJ biochemist to research into mechanisms that control gene expression in mitochondria

Dmitry Temiakov, PhD, a biochemist at the University of Medicine and Dentistry of New Jersey-School of Osteopathic Medicine, has received a five-year, $1.5 million grant from the National Institutes of Health (NIH) to fund research into the molecular mechanisms that control gene expression in mitochondria, the organelles that are the "power plants" of cellular activity.

Study identifies neural pathways tied to eating for pleasure

New research from the University of Georgia has identified the neural pathways in an insect brain tied to eating for pleasure, a discovery that sheds light on mirror impulsive eating pathways in the human brain.

Junk food during pregnancy changes development of opioid signaling pathway in the baby's brain

Here's another reason why a healthy diet during pregnancy is critical to the future health of your children: New research published in the March 2013 issue of The FASEB Journal, suggests that pregnant mothers who consume junk food actually cause changes in the development of the opioid signaling pathway in the brains of their unborn children.

Stem cell line could also advance research into liver cancers, cystic fibrosis

Chronic or acute, liver failure can be deadly. Toxins take over, the skin turns yellow and higher brain function slows. "There is no effective therapy at the moment to deal with the toxins that build up in your body," said Neil Talbot, a Research Animal Scientist for the USDA Agricultural Research Service. "Their only option now is to transplant a liver."

Researchers discover unrecognized mechanism by which PI3K sustains proliferation of cancer cells

New research published today in the Biochemical Journal describes the discovery of a new cancer target.

Amyloid plaques take about 15 years to build up and then plateau: Study

Researchers have identified a possible treatment window of several years for plaques in the brain that are thought to cause memory loss in diseases such as Alzheimer's. The Mayo Clinic study is published in the Feb. 27 online issue of Neurology, the medical journal of the American Academy of Neurology.

Anti-LG3 associated with high rate of organ rejection during transplantation

A team led by Dr. Marie-Jos-e H-bert from the University of Montreal Hospital* Research Centre (CRCHUM) has discovered a new cause of organ rejection in some kidney transplant patients. Her team has identified a new class of antibodies - anti-LG3 - which when activated lead to severe rejection episodes associated with a high rate of organ loss.

Blocking aPKC activity can stop growth of transplanted skin tumors resistant to vismodegib

Hailed as a major step forward in the effort to develop targeted cancer therapies, a recently approved drug for the most common type of skin cancer has been a mixed blessing for patients. Although the initial response is usually dramatic, the tumors often recur as the cancer becomes resistant to treatment.

Engineering chemotherapy drugs' shape increases their ability to target and inhibit cancer cells

Bioengineering researchers at University of California, Santa Barbara have found that changing the shape of chemotherapy drug nanoparticles from spherical to rod-shaped made them up to 10,000 times more effective at specifically targeting and delivering anti-cancer drugs to breast cancer cells.

Mutant HSP70i protein may offer potent treatment opportunities for vitiligo

Loyola University Chicago Stritch School of Medicine researchers have developed a genetically modified protein that dramatically reverses the skin disorder vitiligo in mice, and has similar effects on immune responses in human skin tissue samples.

Reintroducing normal microbial diversity can eliminate VRE from intestinal tracts

Too much antibiotic can decimate the normal intestinal microbiota, which may never recover its former diversity. That, in turn, renders the GI tract vulnerable to being colonized by pathogens. Now researchers from Memorial Sloan-Kettering Cancer Center, New York, NY, and Centro Superior de Investigaci-n en Salud P-blica, Valencia, Spain, show that reintroducing normal microbial diversity largely eliminated vancomycin-resistant enterococci (VRE) from the intestinal tracts of mice..

Elevated cell sugar concentrations increase hyaluronan production and promote cancer growth

According to a recent University of Eastern Finland (UEF) study, elevated cell sugar concentrations increase the production of hyaluronan which, in turn, promotes cancer growth. Regulating the production of hyaluronan may be a way to prevent the spreading of cancer.

Researchers identify 25 human proteins that may be crucial for HIV-1 infection and survival

Studying HIV-1, the most common and infectious HIV subtype, Johns Hopkins scientists have identified 25 human proteins "stolen" by the virus that may be critical to its ability to infect new cells. HIV-1 viruses capture many human proteins from the cells they infect but the researchers believe these 25 proteins may be particularly important because they are found in HIV-1 viruses coming from two very different types of infected cells.

Study indicates how gastric bypass reverses diabetes

In a substudy of the STAMPEDE trial (Surgical Therapy And Medications Potentially Eradicate Diabetes Efficiently), Cleveland Clinic researchers have found that gastric bypass surgery reverses diabetes by uniquely restoring pancreatic function in moderately obese patients with uncontrolled type 2 diabetes.

Scientists identify two populations of human cells that migrate to the intestine

Researchers at Wake Forest Baptist Medical Center and colleagues have identified a special population of adult stem cells in bone marrow that have the natural ability to migrate to the intestine and produce intestinal cells, suggesting their potential to restore healthy tissue in patients with inflammatory bowel disease (IBD).

Study designs and tests 60 compounds for their ability to kill human cancer cells

Inspired by a chemical that fungi secrete to defend their territory, MIT chemists have synthesized and tested several dozen compounds that may hold promise as potential cancer drugs.
