HIV cure research: NIH scientists create 2-headed protein to deplete HIV reservoir

Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-lived, latently HIV-infected cells that can start making the virus when a person stops taking anti-HIV drugs. Further studies in animals and people are needed to determine the viability of this approach.

NIH study reveals risk of drug-resistant malaria spreading to Africa

Drug-resistant forms of Plasmodium falciparum, the deadliest species among malaria parasites, are able to infect the type of mosquito that is the main transmitter of malaria in Africa, according to findings from scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and global partners.

Scientists gain insight into origin of tungsten-ditelluride's magnetoresistance

Scientists recently discovered that tungsten ditelluride (WTe2) is electronically three-dimensional with a low anisotropy. Anisotropy reflects the change in properties of a material when the direction of the current or the applied magnetic field is varied.

Superbug infection greatest increase in children ages 1-5

Children are becoming infected with the highly fatal antibiotic resistant bacteria CRE at a much higher rate than the recent past, according to a data analysis by researchers at Rush University Medical Center. The study was published in the Centers for Disease Control's publication Emerging Infectious Diseases on Oct. 14.

Professor Satinder Brar, key guest speaker at Solid Waste Management and Green Economy

Professor Satinder Kaur Brar of the Eau Terre Environnement Research Centre at INRS is the only Quebec fellow of the College of New Scholars, Artists and Scientists of the Royal Society of Canada invited to the international expert workshop Solid Waste Management and Green Economy to be held October 22 and 23, 2015, in Halle, Germany. She will present a case study with significant benefits for the beer industry during her talk "Chitin and Chitosan as Natural Flocculants for Clarification and In-house Enzymes for Haze Removal in a Microbrewery - Sustainable Bioeconomy Case."

New CEO's gender may affect company performance

HOUSTON - (Oct. 20, 2015) - A CEO succession with a gender change may amplify the disruption of the CEO succession process and thus adversely affect company performance, according to a new study by strategic management experts at Rice University and the Central University of Finance and Economics in Beijing. This dynamic will increase the likelihood of the new CEO's early departure, the study found.

Menopausal status a better indicator than age for mammography frequency

(SACRAMENTO, Calif.) -- In a study conducted to inform American Cancer Society breast cancer screening guidelines, UC Davis researcher Diana L. Miglioretti reports a screening mammogram once every two years is safe for postmenopausal women at average risk of breast cancer.

Annual vs. biennial mammography and breast tumor prognostic characteristics

Premenopausal women diagnosed with breast cancer following a biennial screening mammogram were more likely to have bigger more advanced tumors than women screened annually, while postmenopausal women not using hormone therapy had a similar proportion of tumors with less favorable prognostic characteristics regardless of whether their screening mammogram was biennial or annual, according to an article published online by JAMA Oncology.

Later age recommended for first screening mammogram

Among the changes in the American Cancer Society's updated breast cancer screening guideline is that women with an average risk of breast cancer should undergo regular, annual screening mammography beginning at age 45 years, with women having an opportunity to choose to begin annual screening as early as age 40; women 55 years and older should transition to screening every other year (vs annual), but still have the opportunity to continue with annual screening; and routine screening clinical breast examination is no longer recommended, according to an article in the October 20 issue of J

Tdap vaccination during pregnancy following other recent tetanus-containing vaccine

Among women who received the tetanus, diphtheria, and acellular pertussis (Tdap) vaccine during pregnancy, there was no increased risk of adverse events in the mothers or adverse birth outcomes in newborns for women who had received a tetanus-containing vaccine in the previous 5 years, according to a study in the October 20 issue of JAMA.

Effect of duration of storage of red blood cells transfused for cardiac surgery

Although some studies have suggested that transfusion of stored red blood cell (RBC) concentrates may be harmful, as blood undergoes several physiological changes during storage, an analysis of patients who underwent cardiac surgery in Sweden over a 16-year period found no association between duration of RBC storage and risk of death or serious complications, according to a study in the October 20 issue of JAMA.

Transfusion with stored blood safe in heart surgery

A large registry study led from Sweden's Karolinska Institutet shed new light on the much debated issue of transfusions with stored blood. The study, which is published in the journal JAMA, shows that the use of stored blood units does not influence patient outcomes after heart surgery.

A new way to starve lung cancer?

Scientists have identified a new way to stop the growth of lung cancer cells, by blocking their ability to use alternative sources of nutrition. The discovery was made possible by identifying the metabolic programs used by cancer cells to fuel their growth. The findings point to possible new avenues for treating lung cancer, which is the second most common cancer and accounts for over one-quarter of all cancer-related deaths. The results of the study were published Oct. 15 in the journal Molecular Cell.

What cancer cells 'eat'

Inherent mindfulness linked to lower obesity risk, belly fat

PROVIDENCE, R.I. -- A study of nearly 400 people finds that those who exhibited more 'dispositional mindfulness', or awareness of and attention to their current feelings and thoughts, were less likely to be obese and had less abdominal fat than people who did not exhibit as much of that awareness.

Dispositional mindfulness is not the same as mindfulness meditation, in which people make a conscious, focused practice of attending to their current state and sensations. Instead, it's more of an inherent personality trait, though it can also be taught.

Lathering up with sunscreen may protect against cancer -- killing coral reefs worldwide

Lathering up with sunscreen may prevent sunburn and protect against cancer, but it is also killing coral reefs around the world.

That's the conclusion of a team of international scientists, which includes University of Central Florida professor and diving enthusiast John Fauth.
