Calcium receptor – potential drug target for sleeping sickness

While its common name may make it sound almost whimsical, sleeping sickness, or African trypanosomiasis, is in reality a potentially fatal parasitic infection that has ravaged populations in sub-Saharan Africa for decades, and it continues to infect thousands of people every year.

Researchers identify molecular mechanism that regulates autophagy

Researchers at the University of California, San Diego School of Medicine have identified a molecular mechanism regulating autophagy, a fundamental stress response used by cells to help ensure their survival in adverse conditions.

New math model may help predict colon cancer resistance to chemotherapy

Scientists may be able to better predict which patients with colorectal cancer will respond to chemotherapy using a new mathematical model that measures the amount of stress required for a cancer cell to die without harming healthy tissue. The results of this study are published in Cancer Research, a journal of the American Association for Cancer Research.

Researchers identify signaling pathway used by malarial parasites to destroy host cells

One of the most insidious ways that parasitic diseases such as malaria and toxoplasmosis wreak their havoc is by hijacking their host's natural cellular processes, turning self against self.

New method can visualize aging and tumor growth in real-time

In a study published in the January 18 issue of Cell, researchers from the University of North Carolina Lineberger Comprehensive Cancer Center have developed a new method to visualize aging and tumor growth in mice using a gene closely linked to these processes.

Study examines consequences of muscle activity with surprising results

A study in The Journal of General Physiology examines the consequences of muscle activity with surprising results, indicating that the extracellular accumulation of potassium that occurs in working muscles is considerably higher than previously thought.

Penn Medicine to establish new center for treatment and research of blood diseases

Penn Medicine will establish the Philadelphia region's first dedicated center for the treatment and research of blood diseases by combining the expertise of physicians who specialize in the care of blood disorder patients of all ages along with basic science and clinical researchers who are working to advance treatments for these illnesses.

Medications often prescribed for PAH could affect heart health of treated patients

A research team with the Faculty of Medicine & Dentistry at the University of Alberta reported findings that significantly improve understanding of how widely used drugs in Pulmonary Arterial Hypertension (PAH) affect the heart health of treated patients.

mTorc1 promotes growth of inflammation-associated colon and gastric cancers

Researchers have identified a complex of proteins that promotes the growth of some types of colon and gastric cancers, and shown that medications that block the function of this complex have the potential to be developed into a new treatment for these diseases.

Stress in adolescence can cause severe mental illness in young adulthood

Working with mice, Johns Hopkins researchers have established a link between elevated levels of a stress hormone in adolescence — a critical time for brain development — and genetic changes that, in young adulthood, cause severe mental illness in those predisposed to it.

92% of voters surveyed favor U.S. support of WHO, Better World Campaign poll shows

A new poll released on Wednesday by the Better World Campaign (BWC) "found that 61 percent of voters see the WHO favorably and 92 percent say the United States should continue contributing money to the agency," The Hill's "Healthwatch" blog reports.

Flu virus can essentially tell time: Research

Scientists have discovered that that the flu virus can essentially tell time, thereby giving scientists the ability to reset the virus' clock and combat it in more effective ways. According to researchers at the Icahn School of Medicine at Mount Sinai, the flu knows how much time it has to multiply, infect other cells, and spread to another human being. If it leaves a cell too soon, the virus is too weak. If it leaves too late, the immune system has time to kill the virus.

Sabutoclax appears to selectively target leukemia stem cells that are responsible for relapses

Researchers at the University of California, San Diego School of Medicine have discovered that hard-to-reach, drug-resistant leukemia stem cells (LSCs) that overexpress multiple pro-survival protein forms are sensitive - and thus vulnerable - to a novel cancer stem cell-targeting drug currently under development.

Lack or excess of CaM kinase II affects heart muscle cell stiffness

A certain enzyme, the CaM kinase II, keeps the cardiac muscle flexible. By transferring phosphate groups to the giant protein titin, it relaxes the muscle cells. This is reported by researchers led by Prof. Dr. Wolfgang Linke of the Institute of Physiology at the Ruhr Universität in the journal Circulation Research. In failing hearts, which don't pump enough blood around the body, the scientists found an overly active CaM kinase II.

Rochester scientists propose new reason why acute myeloid leukemia is so difficult to cure

University of Rochester Medical Center scientists have proposed a new reason why acute myeloid leukemia, one of the most aggressive cancers, is so difficult to cure: a subset of cells that drive the disease appear to have a much slower metabolism than most other tumors cells.

Intermountain Risk Score tool can predict mortality among trauma patients

A simple, inexpensive blood test performed on trauma patients upon admission can help doctors easily identify patients at greatest risk of death, according to a new study by researchers at Intermountain Medical Center in Salt Lake City.

Enrollment complete in GlycoMimetics’ GMI-1070 Phase 2 study for sickle cell disease

GlycoMimetics, Inc. (GMI), a clinical-stage biotechnology company researching a new class of glycobiology-based therapies for a broad range of diseases, today announced that it has completed enrolling patients in its Phase 2 study of GMI-1070, its lead investigational drug candidate.

Study finds key association between Kallikrein 6 and malignant tumors

One of the most common types of brain tumors in adults, glioblastoma multiforme, is one of the most devastating. Even with recent advances in surgery, radiation and chemotherapy, the aggressive and invasive tumors become resistant to treatment, and median survival of patients is only about 15 months. In a study published in Neuro-Oncology, researchers at Mayo Clinic identify an important association between the naturally occurring enzyme Kallikrein 6, also known as KLK6, and the malignant tumors.

New compounds can target RNase H enzyme in HIV

Scientists who study HIV are facing a troubling consequence of their own success. They created drugs that can now give infected patients almost normal life expectancy. However, those same drugs will eventually cause the constantly mutating virus to evolve into a form that eludes current treatments.

SyNAPSe® Trial by BHR Pharma deemed to have no safety issues according to DSMB

BHR Pharma, LLC announced today that the SyNAPSe® Trial's independent Data and Safety Monitoring Board (DSMB) evaluated safety data from 803 randomized patients and determined that no issues exist; therefore, the trial may continue towards its intended completion.
