Researchers find genetic variability in frozen vials of cells purchased from same cell bank

In a surprise finding, researchers working with breast cancer cells purchased at the same time from the same cell bank discovered that the cells responded differently to chemicals, even though the researchers had not detected any difference when they tested them for authenticity at the time of purchase.

Study finds biological basis for gastrointestinal symptoms in people with non-celiac wheat sensitivity

A new study may explain why people who do not have celiac disease or wheat allergy nevertheless experience a variety of gastrointestinal and extra-intestinal symptoms after ingesting wheat and related cereals.

Yale researchers develop new system to simultaneously edit multiple genes

A Yale research team has designed a system to modify, or edit, multiple genes in the genome simultaneously, while also minimizing unintended effects.

Mice study shows stem cell infusion could help treat glaucoma

An infusion of stem cells could help restore proper drainage for fluid-clogged eyes at risk for glaucoma. That's the upshot of a study led by a Veterans Affairs and University of Iowa team.

Scientists discover modified human protein involved in Ebola virus replication

A newly identified requirement of a modified human protein in ebolavirus (EBOV) replication, may unlock the door for new approaches to treating Ebola.

Penn researchers use iron-containing nanoparticles to reduce plaque and prevent tooth decay

The bacteria that live in dental plaque and contribute to tooth decay often resist traditional antimicrobial treatment, as they can "hide" within a sticky biofilm matrix, a glue-like polymer scaffold.

Stereotactic radiosurgery could be more effective for patients with few metastatic brain tumors

Patients with three or fewer metastatic brain tumors who received treatment with stereotactic radiosurgery (SRS) had less cognitive deterioration three months after treatment than patients who received SRS combined with whole brain radiation therapy (WBRT).

Researchers discover three new risk genes for ALS

Published today in Nature Genetics, the study reveals three new risk genes for ALS and one of these - C21orf2 - increases an individual's risk of developing the dis-ease by 65 per cent.

Scientists clarify mechanism of defective immune defense in G6PD patients

Favism is a common hereditary disease, affecting around 400 million people worldwide. It is caused by a lack of the enzyme glucose-6-phosphate dehydrogenase (G6PD).

Large study of familial ALS finds new gene variant present in 3% of all patients with disease

Variations in a gene with multiple functions in neurons are present in approximately 3 percent of all cases of ALS in North American and European populations, both sporadic and familial, making it one of the most common genetic causes of the disease, according to a paper published in Nature Genetics.

Odor identification test may help detect early-stage Alzheimer's disease

Researchers from Columbia University Medical Center, New York State Psychiatric Institute, and NewYork-Presbyterian reported that an odor identification test may prove useful in predicting cognitive decline and detecting early-stage Alzheimer's disease.

Liquid biopsies hold potential for detecting NSCLC EGFR mutations, predicting cancer recurrence

Three manuscripts published in the recent issue of the Journal of Thoracic Oncology, the official journal of the International Association for the Study of Lung Cancer, explored the versatility of liquid biopsies by identifying EGFR mutations using circulating tumor DNA (ctDNA) in urine and plasma and examining circulating tumor cells (CTCs) in plasma to predict the risk of lung cancer recurrence after surgical resection.

Researchers identify genetic variants linked to radiotherapy side-effects in prostate cancer patients

A new study involving researchers from The University of Manchester looked at the genetic information of more than 1,500 prostate cancer patients and identified two variants linked to increased risk of radiotherapy side-effects.

Study identifies key risk factors involved in patient-to-patient transmission of drug-resistant bacteria

Three key factors increase the risk for patient-to-patient transmission of an extremely drug-resistant bacteria known as CP-CRE, according to a new study published today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.
