Xcelligence System provides real-time detection of neuronal cell death

Time course analyses of neuronal cell death and its underlying mechanisms require laborious experiments and multiple endpoint assays, often involving labelling with irritating compounds and cell disruption. A recent study used the xCELLigence System of Roche to investigate the response of the neuronal-like cell line HT-22 and cultured primary rat cortical neurons to different cell death stimuli and neuroprotectants.

Scientists develop rapid diagnostic test for detecting meningococcal bacteria

Researchers at Queen's University Belfast and the Belfast Health and Social Care Trust have developed a groundbreaking test for meningitis which could help save lives.A rapid diagnostic test for meningococcal bacteria that can produce results within an hour has been developed by scientists from Queen's Centre for Infection and Immunity and the Trust. The speed of this new test is a vital factor in the treatment of young children with meningococcal meningitis and septicaemia who become very ill over a short period.

Research shows mutation in Prox1 gene may lead to memory, learning problems

St. Jude Children's Research Hospital investigators showed a gene named Prox1 is a key player in normal development of a brain structure crucial for learning and memory and remains active throughout life, nurturing the cells vital for making new memories.This study focused on a small region of the hippocampus known as the dentate gyrus, a brain structure needed for memory and learning that is home to the subgranular zone where the neural stem cells destined to become granule cells are housed. The dentate gyrus is one of two regions of the adult brain where neural stem cells continue to produce the precursor cells that ultimately differentiate into neurons.

Genome-wide study identifies key genetic variant associated with nonalcoholic fatty liver disease

Researchers at Massachusetts General Hospital found that patients with nonalcoholic fatty liver disease (NAFLD) who carry an allele of the PNPLA3 gene have an increased risk of developing advanced disease, including nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. A second study supported by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) validates these findings and further concludes that in pediatric patients, the same allele is associated with earlier disease presentation.

Advanced Cell Technology to obtain patent for cellular reprogramming, generation of iPS cells

Advanced Cell Technology, Inc. announced today that it is positioned to obtain significant patents relating to cellular reprogramming and the generation of induced pluripotent stem (iPS) cells. iPS cells are similar to embryonic stem (ES) cells, except they are generated from adult cells such as skin using certain reprogramming factors, without the controversial use of embryos. Although human iPS cells were first produced in 2007, ACT has been working on inducing pluripotency, with positive results, for more than a decade. The Company's efforts go back to the 1990s, providing (through existing patent filings and continuations) some of the earliest priority dates in the field.

Mature stem cell research development hinges on quality of science peer review

Are there too many stem cell research journals? This question has been posed by Drs. Paul Sanberg and Cesar Borlongan of the Department of Neurosurgery and Brain Repair at the University of South Florida. Their article appears in the current issue of Stem Cell Reviews and Reports.Both Sanberg and Borlongan are concerned about the quality of the science being published in the proliferating stem cell journals.

Researcher unveils unique stem cell partnership that can lead to advances in regenerative medicine

A study led by a researcher at Albert Einstein College of Medicine of Yeshiva University has revealed a unique "partnership" between two types of bone marrow stem cells, which could lead to advances in regenerative medicine. The aim of regenerative medicine is to enable the body to repair, replace, restore or regenerate damaged or diseased cells, tissues and organs.

Review on energy drinks that claim athletic performance enhancement

Popular energy drinks promise better athletic performance and weight loss, but do the claims hold up? Not always, say researchers at Nova Southeastern University in Florida."Energy drinks typically feature caffeine and a combination of other ingredients, including taurine, sucrose, guarana, ginseng, niacin, pyridoxine and cyanocobalamin," says Stephanie Ballard, PharmD., assistant professor of pharmacy practice at Nova Southeastern University's West Palm Beach campus.

Researchers develop genetically mutated stem cells for myelin research

Vanishing White Matter (VWM) disease is a devastating condition that involves the destruction of brain myelin due to a mutation in a central factor. To understand the disease and test potential treatments that could apply to other disorders, such as multiple sclerosis, Prof. Orna Elroy-Stein of Tel Aviv University's Department of Cell Research and Immunology is leading a scientific breakthrough by developing laboratory mice which carry the VWM mutation an important new tool.

Long-term entecavir therapy suppresses HBV DNA, normalizes ALT and improves liver histology

Researchers from this international study found that patients with chronic hepatitis B virus (HBV) infection who received at least 3 years of cumulative entecavir (antiviral) therapy achieved substantial histologic improvement and regression of fibrosis or cirrhosis. Full details of the study appear in the September issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD).
