Study identifies KNDy neurons as a likely control switch of hot flushes

Hot flushes affect millions of people, and not just women. Yet, it is still unclear what causes the episodes of temperature discomfort, often accompanied by profuse sweating.

Blocking myeloid-derived suppressor cells after lymphopenia improves adoptive T-cell therapy

Researchers at the Moffitt Cancer Center have found that delayed tumor growth and enhanced survival of mice bearing melanoma were possible by blocking the reconstitution of myeloid-derived suppressor cells and Tregs (suppressors of anti-tumor activity) after total body irradiation had eliminated them. Blocking myeloid-derived suppressor cells and regulatory T-cell reconstitution improved adoptive T-cell therapy, an immunotherapy designed to suppress tumor activity.

Autism associated with reductions in cellular adhesion molecules in the blood

A new study published in Biological Psychiatry suggests that autism is associated with reductions in the level of cellular adhesion molecules in the blood, where they play a role in immune function.

SIRT6 protein may play a critical role in blocking cancer and controlling cellular metabolism

A new study sheds more light on how an anti-aging gene suppresses cancer growth, joint University of Michigan Health System and Harvard Medical School research shows.

Study shows how osteocalcin plays a significant role in bone strength

A new study from engineering researchers at Rensselaer Polytechnic Institute shows, for the first time, how the little-understood protein osteocalcin plays a significant role in the strength of our bones. The findings could lead to new strategies and therapeutics for fighting osteoporosis and lowering the risk of bone fracture.

Bacteriophages may play an important role in competition among bacterial strains

Unique viruses called bacteriophages may play an important role in competition among bacterial strains, influencing the overall ecosystem of the human intestine, scientists at The University of Texas at Arlington and UT Southwestern Medical Center say.

New coronavirus can infect cells from humans and bats alike

The SARS epidemic of 2002-2003 was short-lived, but a novel type of human coronavirus that is alarming public health authorities can infect cells from humans and bats alike, a fact that could make the animals a continuing source of infection, according to a study to be published in in mBio-, the online open-access journal of the American Society for Microbiology, on December 11.

Carbon nanotubes can help regulate chloride levels in nerve cells that contribute to neural injuries

A nanomaterial engineered by researchers at Duke can help regulate chloride levels in nerve cells that contribute to chronic pain, epilepsy, and traumatic brain injury.

Study finds high serum galectin-1 levels in Hodgkin lymphoma patients

Blood levels of an immunity-related protein, galectin-1, in patients with newly diagnosed Hodgkin lymphoma reflected the extent of their cancer and correlated with other predictors of outcome, scientists reported at the American Society of Hematology annual meeting.

Pfizer's PD0325901 experimental drug blocks untreatable NF1 tumors

Researchers conducting a preclinical study in mice successfully used targeted molecular therapy to block mostly untreatable nerve tumors that develop in people with the genetic disorder Neurofibromatosis 1 (NF1).

Bolstering extracellulal matrix prevents skin aging

As we get older, the trillions of cells in our body do too. And like us, they become less resilient and able to weather the stress of everyday life. Our skin especially tells the tale of what's happening throughout our bodies.

Weill Cornell research team develops new experimental drug therapy to target DLBCL

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin's lymphoma and the seventh most frequently diagnosed cancer. The most chemotherapy resistant form of DLBCL, called activated B-cell - DLBCL (ABC-DLBCL), remains a major therapeutic challenge.

Lack of TDP-43 protein can lead to frontotemporal dementia/ALS

Researchers at Mayo Clinic in Florida have uncovered a toxic cellular process by which a protein that maintains the health of neurons becomes deficient and can lead to dementia.

Transplanting spermatogonial stem cells could restore fertility in male cancer patients

Radiation and chemotherapy can pack a powerful punch against all kinds of cancers. Those who survive, however, are often left with bad news: Their treatments have rendered them infertile.

FAC PET identifies liposarcoma tumors that are sensitive to chemotherapy

Liposarcoma, the most common type of sarcoma, is an often lethal form of cancer that develops in fat cells. It is particularly deadly, in part, because the tumors are not consistently visible with positron emission tomography (PET) scans that use a common probe called FDG and because they frequently do not respond to chemotherapy.
