Equol conversion status influences soy food effects on menopause symptoms

Northridge, Calif. (November 12, 2012) – Eating more soy was associated with larger reductions in menopausal vasomotor symptoms (VMS), such as hot flashes, among U.S. women that can convert soy to a compound called equol, according to data from a first-of-its-kind study presented in an oral session at the North American Menopause Society (NAMS) 2012 annual meeting.

Gene sequencing project identifies abnormal gene that launches rare childhood leukemia

Research led by the St. Jude Children's Research Hospital – Washington University Pediatric Cancer Genome Project has identified a fusion gene responsible for almost 30 percent of a rare subtype of childhood leukemia with an extremely poor prognosis.

The finding offers the first evidence of a mistake that gives rise to a significant percentage of acute megakaryoblastic leukemia (AMKL) cases in children. AMKL accounts for about 10 percent of pediatric acute myeloid leukemia (AML). The discovery paves the way for desperately needed treatment advances.

UT Arlington physics team demonstrates new power generation technique

A University of Texas at Arlington physics professor has helped create a hybrid nanomaterial that can be used to convert light and thermal energy into electrical current, surpassing earlier methods that used either light or thermal energy, but not both.

Working with Louisiana Tech University assistant professor Long Que, UT Arlington associate physics professor Wei Chen and graduate students Santana Bala Lakshmanan and Chang Yang synthesized a combination of copper sulfide nanoparticles and single-walled carbon nanotubes.

Study shows how chronic inflammation can cause cancer

  • Chronic inflammation like sunburn can sometimes cause cancer, but how it happens remains unknown.
  • This study shows for the first time how a substance made by the body to promote inflammation can cause an aggressive form of leukemia.
  • This knowledge enabled the researchers to develop a possible treatment for the leukemia.

Home field advantage: Intravaginal immunization may help protect against infection

Sexually-transmitted diseases (STDs) enter the body through the mucosal epithelial cells and the ability to direct pathogen-clearing T-cells to points of infection may be the critical element in developing successful vaccines against these infections.

In a study published in the Journal of Clinical Investigation, researchers led by John Schiller at the National Cancer Institute investigated the immune response to intravaginal immunization in mice infected with a form of the HPV virus carrying a model antigen.

HIV-1 vaccine development: Pinning down a moving target

HIV-1 is a genetically diverse collection of viruses, making it a moving target in vaccine development. In a study published in the Journal of Clinical Investigation, researchers led by Brad Jones at the University of Toronto in investigated the feasibility of eliminating HIV-infected cells by targeting cellular immune responses against a human endogenous retrovirus (HERV). HERVs are the DNA remnants of ancient infectious retroviruses that became part of the germ line cells of our ancestors.

Scientists at IRB BARCELONA discover a key process that allows colon cancer to metastasize

A team of 17 researchers, led by scientists Eduard Batlle and Elena Sancho in the Colorectal Cancer Laboratory at the Institute for Research in Biomedicine (IRB Barcelona), have determined that the ability of colon cancer to metastasize lies in the healthy cells, called stroma, that surround the tumour. Although the stroma has long been hypothesized to be complicit in this process, this study marks the first time that healthy cells in the microenvironment have been observed to play a fundamental role in allowing metastasis to occur in a specific tumour type.

National study shows protective eyewear reduces eye, head, and facial injuries

PROVIDENCE, R.I. – A new study conducted by researchers at Hasbro Children's Hospital, the Center for Injury Research and Policy of The Research Institute at Nationwide Children's Hospital, Fairfax (VA) County Public Schools, and Boston Children's Hospital has found that high school field hockey players competing in states with mandated protective eyewear have significantly lower rates of head, eye, and facial injuries when compared to players who compete in states without protective eyewear mandates.

New cause of thyroid hormone deficiency discovered

International researchers, including a team at McGill University, have discovered a new cause for thyroid hormone deficiency, or hypothyroidism. This common endocrine disorder is typically caused by problems of the thyroid gland, and more rarely, by defects in the brain or the pituitary gland (hypophysis). However, a new cause of the disease has been discovered from an unsuspected source and is reported in the journal Nature Genetics.

Persistence or extinction: Through a mathematical lens

Philadelphia, PA—Scientists have estimated that there are 1.7 million species of animals, plants and algae on earth, and new species continue to be discovered. Unfortunately, as new species are found, many are also disappearing, contributing to a net decrease in biodiversity. The more diversity there is in a population, the longer the ecosystem can sustain itself. Hence, biodiversity is key to ecosystem resilience.

List of diseases spread by deer tick grows, along with their range

ATLANTA (November 12, 2012)—An emerging tick-borne disease that causes symptoms similar to malaria is expanding its range in areas of the northeast where it has become well-established, according to new research presented today at the annual meeting of the American Society of Tropical Medicine and Hygiene (ASTMH).

Genetic link between pancreatitis and alcohol consumption, says Pitt team

PITTSBURGH, Nov. 12, 2012 – A new study published online today in Nature Genetics reveals a genetic link between chronic pancreatitis and alcohol consumption.

Robots enable scar-free hysterectomies for some women

AUGUSTA, Ga. – The precision and three-dimensional view provided by robots can enable essentially scar-free surgery for some women needing hysterectomies, physicians report.

Smart drug improves survival in older patients with acute myeloid leukemia

A new study has found Acute Myeloid Leukaemia (AML) patients given a new type of 'smart drug' in addition to chemotherapy treatment are 22 per cent less likely to relapse and around 13 per cent less likely to die from their disease. The results are from a major phase III Cancer Research UK-funded trial led by Cardiff University.
