Scientists show how pluripotent stem cells mobilize in wounded planarian worms

The skin, the blood, and the lining of the gut-adult stem cells replenish them daily. But stem cells really show off their healing powers in planarians, humble flatworms fabled for their ability to rebuild any missing body part. Just how adult stem cells build the right tissues at the right times and places has remained largely unanswered.

Dysfunctional RyRs play a role in stress-induced cognitive dysfunction

ARMGO Pharma, Inc., a biopharmaceutical company developing innovative small molecule drugs known as "Rycals™," which act on the ryanodine receptor calcium-release channel (RyR), announced that a study published today in the prestigious scientific journal Cell reveals the underlying role of calcium leak through the RyR as an important contributor to stress-induced cognitive dysfunction.

Researchers define new treatment for potentially fatal lung disease in patients with CVID

A team of researchers at the Medical College of Wisconsin and Children's Hospital of Wisconsin Research Institute defined a new treatment for a potentially fatal lung disease in patients with a primary immunodeficiency known as common variable immunodeficiency (CVID).

Study may spur research into multi-model imaging based biomarker development for AD

Alzheimer's disease (AD) is one of the most common brain disorders, with an estimated 35 million people affected worldwide. In the last decade, research has advanced our understanding of how AD affects the brain. However, diagnosis continues to rely primarily on neuropsychological tests which can only detect the disease after clinical symptoms begin. In a supplement to the Journal of Alzheimer's Disease, investigators report on the development of imaging-based biomarkers that will have an impact on diagnosis before the disease process is set in motion.

Concentration increase of HUWE1 protein leads to intellectual disability

2 to 3 % of the children are born with an intellectual disability. Possibly by a genetic defect, but in 80% of these cases, we do not know - yet - which genes are responsible. VIB researchers at KU Leuven show that increased production of the HUWE1 protein is the cause in some patients.

Well-known protein plays central role in development of acute pancreatitis

There is now a clear target for the treatment of acute pancreatitis, according to researchers at Lund University in Sweden, who have discovered that a well-known protein plays a central role in the development of the disease. It is likely that the protein is also highly significant for other inflammatory diseases.

Prenatal exposures to polyfluoroalkyl compounds may lead to obesity in babies

Pregnant women who are highly exposed to common environmental chemicals - polyfluoroalkyl compounds (PFCs) - have babies that are smaller at birth and larger at 20 months of age, according to a study from Emory University's Rollins School of Public Health published online in the August 30 edition of Environmental Health Perspectives.

Scientists identify specific role of RESA protein in modulating blood circulation

When the parasite responsible for malaria infects human red blood cells, it launches a 48-hour remodeling of the host cells. During the first 24 hours of this cycle, a protein called RESA undertakes the first step of renovation: enhancing the stiffness of the cell membranes.

Research identifies new pathway to target with anti-inflammatory drugs

Scientists' discovery of an important step in the body's process for healing wounds may lead to a new way of treating inflammation.

Researchers identify several genetic factors linked to C-reactive protein

African Americans have higher blood levels of a protein associated with increased heart-disease risk than European Americans, despite higher "good" HDL cholesterol and lower "bad" triglyceride levels. This contradictory observation now may be explained, in part, by a genetic variant identified in the first large-scale, genome-wide association study of this protein involving 12,000 African American and Hispanic American women.

Study explains why some cancer vaccines are not as effective as hoped

A research report published in the September 2012 issue of the Journal of Leukocyte Biology offers a possible explanation of why some cancer vaccines are not as effective as hoped, while at the same time identifies a new therapeutic strategy for treating autoimmune problems. In the report, scientists suggest that cancer, even in the very early stages, produces a negative immune response from dendritic cells, which prevent lymphocytes from working against the disease.

Scientists establish genetic mouse model for primary ovarian insufficiency

Scientists have established a genetic mouse model for primary ovarian insufficiency (POI), a human condition in which women experience irregular menstrual cycles and reduced fertility, and early exposure to estrogen deficiency.

S107 drug can prevent learning and memory deficits associated with stress-related disorders

Columbia University Medical Center (CUMC) researchers have identified a potential medical treatment for the cognitive effects of stress-related disorders, including post-traumatic stress disorder (PTSD).

Type 2 diabetics with normoalbuminuria more likely to develop heart problems

In individuals with type 2 diabetes, any degree of measurable urinary protein excretion—even in what is considered the normal range—increases their risk of experiencing heart problems, according to a study appearing in an upcoming issue of new study in the Journal of the American Society of Nephrology (JASN).

Weill Cornell Medical College receives three new research grants for translational blood cancer study

Weill Cornell Medical College has been awarded three new research grants from the Leukemia & Lymphoma Society totaling $1.8 million. The funds will support critically-needed translational research for blood cancers, accelerating promising discoveries from the laboratory to the patient's bedside.

Healthy diets during infancy and early childhood can prevent obesity in future

Rats born to mothers fed high-fat diets but who get normal levels of fat in their diets right after birth avoid obesity and its related disorders as adults, according to new Johns Hopkins research.

Soligenix’s RiVax induces greater ricin neutralizing antibody levels in humans

Soligenix, Inc., a development stage biopharmaceutical company, announced today the results of a Phase 1B clinical trial of an aluminum hydroxide (Alum) adjuvanted formulation of RiVax, designed to improve the immunogenicity of the vaccine.

Researchers discover new immune response mechanism during infection

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a new "first response" mechanism that the immune system uses to respond to infection. The findings challenge the current understanding of immunity and could lead to new strategies for boosting effectiveness of all vaccines. The study, conducted in mice, published online today in the journal Immunity.

Studies examine how PML gene regulates the fatty acid oxidation pathway

Two papers led by scientific teams from the Cancer Genetics Program at Beth Israel Deaconess Medical Center (BIDMC) shed new light on the genetic mechanisms underlying cellular energy and metabolism and, at the same time, highlight both the challenges and opportunities of genetic approaches to cancer treatment.
