Biomimetic bioartificial livers and cell toxicity assays: an interview with Dr. Joris Braspenning, CEO Medicyte

Biomimetic bioartificial livers are liver organoids based on synthetic equivalents of the human extracellular matrix (ECM) which will be seeded with human cells.

Hydroxychloroquine fails to modify HIV in patients not taking ART

The use of hydroxychloroquine does not reduce CD8 cell activation in HIV-infected patients not taking antiretroviral therapy, research shows.

Study extends scientific understanding of how pheromones activate the vomeronasal organ

The vomeronasal organ (VNO) is one of evolution's most direct enforcers. From its niche within the nose in most land-based vertebrates, it detects pheromones and triggers corresponding basic-instinct behaviors, from compulsive mating to male-on-male death matches. A new study from the Stowers Institute for Medical Research, published online in Nature Neuroscience on July 29, 2012, extends the scientific understanding of how pheromones activate the VNO, and has implications for sensory transduction experiments in other fields.

Neurotez receives U.S. patent for Leptin to treat Alzheimer's

Neurotez, Inc. today announced the grant of U.S. Patent number 8,227,408 by the United States Patent and Trademark Office covering the company's lead product candidate, Leptin. The patent protects use of the hormone Leptin for treating a progressive cognitive disease, disorder or condition, such as Alzheimer's disease (AD), resulting from accumulation of an amyloid peptide or for improving resilience of cognitive function by modulating the accumulation of the amyloid peptide in brain.

OX40 molecule responsible for airway inflammation in the lungs

A research team led by Xian Chang Li, MD, PhD, Brigham and Women's Hospital (BWH) Transplantation Research Center, has shed light on how a population of lymphocytes, called CD4+ T cells, mature into various subsets of adult T helper cells.

Novel method of identifying molecules that can help prevent diabetes

Pancreatic beta cells produce insulin, responsible for controlling blood sugar levels and thus essential for our survival. Among the numerous factors that affect the workings of these cells, a protein called Cx36 was identified a few months ago by a research team at the UNIGE.

Novel technique allows scientists to assay tumor invasion attributable to interstitial fluid

There are many factors that affect tumor invasion, the process where a tumor grows beyond the tissue where it first developed. While factors like genetics, tissue type and environmental exposure affect tumor metastasis and invasion, physical forces like fluid flow remain a poorly understood component of tumor invasion. A new video article in JoVE, the Journal of Visualized Experiments, describes a novel procedure that allows researchers to study and test the microenvironment of a growing tumor.

Child who received first stem cell trachea transplant functioning well two years on

The first child stem cell-supported trachea transplant is functioning well two years on, according to an Article published Online First in The Lancet today. The follow-up of the procedure, carried out in 2010 at Great Ormond Street Hospital (GOSH), shows that the new organ has strengthened and does not appear to have induced any signs of rejection. The 13-year-old boy who received the transplant continues to breathe normally, has grown 11 cm in height and has returned to school. He does not require any anti-rejection therapy.

Single event of brain trauma can lead to Alzheimer’s

A study, performed in mice and utilizing post-mortem samples of brains from patients with Alzheimer’s disease, found that a single event of a moderate-to-severe traumatic brain injury (TBI) can disrupt proteins that regulate an enzyme associated with Alzheimer’s. The paper, published in The Journal of Neuroscience, identifies the complex mechanisms that result in a rapid and robust post-injury elevation of the enzyme, BACE1, in the brain. These results may lead to the development of a drug treatment that targets this mechanism to slow the progression of Alzheimer’s disease.

How an opportunistic fungal pathogen knows when to attack

The opportunistic fungal pathogen Candida albicans inconspicuously lives in our bodies until it senses that we are weak, when it quickly adapts to go on the offensive. The fungus, known for causing yeast and other minor infections, also causes a sometimes-fatal infection known as candidemia in immunocompromised patients. An in vivo study, published in mBio, demonstrates how C. albicans can distinguish between a healthy and an unhealthy host and alter its physiology to attack.

Moderate-to-severe TBI can disrupt proteins that regulate enzyme associated with Alzheimer's

A study, performed in mice and utilizing post-mortem samples of brains from patients with Alzheimer's disease, found that a single event of a moderate-to-severe traumatic brain injury (TBI) can disrupt proteins that regulate an enzyme associated with Alzheimer's.

Human brown fat may actually be beige

Beige fat cells are more closely related to white than brown fat cells, say researchers who found that brown fat deposits in humans appear to be composed of beige cells.

Herbal therapy no alternative in HCV infection

The commonly used herbal remedy, silymarin, offers no benefit to patients with treatment-resistant hepatitis C virus infection, a study shows.

Study explores role of L. reuteri against foodborne infection

While many bacteria exist as aggressive pathogens, causing diseases ranging from tuberculosis and cholera, to plague, diphtheria and toxic shock syndrome, others play a less malevolent role and some are critical for human health.

Placenta-derived endothelial colony-forming cells are more vasculogenic: Study

A study comparing whether endothelial colony-forming cells (ECFCs) derived from human placenta or those derived from human umbilical cord blood are more proliferative and better for forming new blood vessels has found that ECFCs derived from human placenta are more vasculogenic.

Bryologs more potent than prostratin in treating HIV

Thanks to antiretrovirals, an AIDS diagnosis hasn't been a death sentence for nearly two decades. But highly active antiretroviral therapy, or HAART, is also not a cure.

Helmholtz-Zentrum Geesthacht to establish Virtual Institute

In collaboration with the university hospitals of Hamburg, Hannover and Graz, as well as further partners, the Helmholtz-Zentrum Geesthacht will establish a Virtual Institute, whose focus will be set on degradable magnesium implants. One aim of the research association coordinated from Geesthacht is to develop first prototypes of orthopedic implants.

Researchers verify role of alpha-synuclein aggregates in vivo

Using a two-photon microscope capable of peering deep within living tissue, researchers at the University of California, San Diego School of Medicine have found new evidence that alpha-synuclein protein build-up inside neurons causes them to not only become "leaky," but also to misfire due to calcium fluxes.
