New analysis of medieval cesspit in Jerusalem provides window into spread of infectious diseases

A new analysis of a medieval cesspit in the Christian quarter of the old city of Jerusalem has revealed the presence of a number of ancient parasite eggs, providing a window into the nature and spread of infectious diseases in the Middle East during the 15th century.

UConn Health cancer epidemiologist reveals effect of artificial light on health

Modern life, with its preponderance of inadequate exposure to natural light during the day and overexposure to artificial light at night, is not conducive to the body's natural sleep/wake cycle.

Gene regulatory code remained same across the evolution

The language used in the switches that turn genes on and off has remained the same across millions of years of evolution, according to a new study led by researchers at Karolinska Institutet in Sweden. The findings, which are published in the scientific journal "eLife", indicate that the differences between animals reside in the content and length of the instructions that are written using this conserved language.

Pathogen may cause high levels of virulence in closely-related hosts

When viruses such as influenza and Ebola jump from one species to another, their ability to cause harm can change dramatically, but research from the University of Cambridge shows that it may be possible to predict the virus's virulence by looking at how deadly it is in closely-related species.

MRD-directed therapy helps boost survival of young leukemia patients

Measuring the concentration of leukemia cells in patient bone marrow during the first 46 days of chemotherapy should help boost survival of young leukemia patients by better matching patients with the right intensity of chemotherapy. St. Jude Children's Research Hospital investigators led the research, which appears in the March 20 edition of the journal Lancet Oncology.

MED15 may serve as prognostic marker for HNSCC recurrence

A new study provides the first evidence that the mediator complex subunit 15 (MED15) may play a crucial role in the pathophysiology of head and neck squamous cell carcinoma (HNSCC). MED15 overexpression was found to be associated with higher mortality rates in HNSCC patients with cancer recurrence, particularly in oral cavity/oropharyngeal tumors, according to the study published in The American Journal of Pathology.

Hypermethylation serves as protective barrier inhibiting development of ALS, FTD

Penn Medicine researchers have discovered that hypermethylation - the epigenetic ability to turn down or turn off a bad gene implicated in 10 to 30 percent of patients with Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Degeneration (FTD) - serves as a protective barrier inhibiting the development of these diseases.

Shp2 enzyme blocks protection program, boosts tumor growth

Cells have two different programs to safeguard them from getting out of control and developing cancer. One of them is senescence (biological aging). It puts cancer cells into a permanent sleep so they no longer divide and grow in an uncontrolled way.

Mutations in hair keratins increase risk for dental defects, caries

Today at the 93rd General Session and Exhibition of the International Association for Dental Research, researcher Olivier Duverger, National Institutes of Health-National Institute of Neurological Disorders and Stroke, Bethesda, Md., USA, will present a study titled "Hair Keratins as Structural Organic Components of Mature Enamel: The Link Between Hair Disorders and Susceptibility to Dental Caries."

Olive ingredients may prevent Alzheimer's disease

It has long been proven that people who follow a Mediterranean diet and keep physically and mentally active are less likely to suffer from dementia. Olives in particular appear to play a key role in this regard. But just what are the substances contained in these small, oval fruit that are so valuable? This is what a Hessen-based group of researchers from the Goethe University Frankfurt, the Technical University of Darmstadt and Darmstadt company N-Zyme BioTec GmbH intends to find out. The three-year project "NeurOliv" has a project volume of 1.3 million Euros and is funded by the Federal Ministry of Education and Research as part of the high-tech initiative "KMU-innovativ Biochance".

Scientists discover how ALL cells mutate to survive chemotherapy

By genomic sequencing of leukemia cells from relapsed patients at different stages, scientists have discovered key details of how acute lymphoblastic leukemia (ALL) cells mutate to survive chemotherapy. These mutations enable the cells to proliferate, causing relapse and often death.
