Children follow same steps to learn vocabulary, regardless of language spoken

Regardless of the language they are learning to speak, young children learn vocabulary in fundamentally the same way, according to a study by researchers at the National Institute of Child Health and Human Development of the National Institutes of Health.

Hypertension :: Inhaled nitrite help babies suffering in a low-oxygen state

Scientists from the National Institutes of Health (NIH) Clinical Center and the Loma Linda University School of Medicine have found that use of an inhaled nitrite spray may help babies diagnosed with persistent pulmonary hypertension of the newborn (PPHN). Premature newborns and those with pneumonia or heart problems often develop PPHN. This often-fatal disease causes high blood pressure in an infant’s lungs and places the baby in a low-oxygen state. The collaborative study findings are reported in “Nature Medicine”.

HIV :: How HIV causes abnormalities in antibody producing cells

HIV wreaks much of its damage by targeting the “orchestra conductor” of the immune system, a key class of T cells — CD4+ T cells — whose destructive relationship with HIV has been well-studied by AIDS researchers. More poorly understood has been the effect of HIV on another key class of immune cells, antibody-producing B cells. The malfunction of B cells in HIV-infected patients was first described more than 20 years ago by H. Clifford Lane, M.D., Anthony S. Fauci, M.D., and colleagues at the National Institute of Allergy and Infectious Diseases (NIAID) of the National Institutes of Health (NIH).

Alzheimer’s disease :: Genetics Facts – Alzheimer’s disease

Scientists do not yet fully understand what causes Alzheimer’s disease (AD). However, the more they learn about AD, the more they become aware of the important function genes play in the development of this devastating disease.

Neurology :: Dopamine receptor & gene responsible for reward learning

Using a new molecular genetic technique, scientists have
turned procrastinating primates into workaholics by
temporarily suppressing a gene in a brain circuit involved
in reward learning. Without the gene, the monkeys lost
their sense of balance between reward and the work required
to get it, say researchers at the NIH’s National Institute
of Mental Health (NIMH).

Diabetes :: American Indians and Alaska Natives at risk for Diabetes

About 40 percent of adults ages 40 to 74 –
or 41 million people – have pre-diabetes, a condition that
raises a person’s risk of developing type 2 diabetes, heart
disease, and stroke. American Indians and Alaska Natives
are 2.3 times as likely to have diabetes as non-Hispanic
whites of similar age.

Alternative Medicine :: Alternative therapies – documented benefits and risks

Empirical and scientific evidence exists to support the benefits of acupuncture, manual therapies and several medicinal plants for chronic or mild conditions.

Allergies :: Antibiotics may cause Allergies, Asthma

University of Michigan Health System presented a study – “Antibiotics cause changes in gastrointestinal tract microbes and alter immune system responses, making people more sensitive to common allergens.”

Women’s Health :: Dysfunctional uterine bleeding & Homeopathy

The term dysfunctional uterine bleeding is used when there is heavy or irregular vaginal bleeding and where uterus, ovaries and fallopian tubes are found to be structurally and organically normal on bimanual examination. DUB occurs most commonly at the beginning and at the end of the reproductive years-shortly after the onset of menstrual cycle in an adolescent girl, when the hypothalamic ovarian axis is depressed because of low estrogen output.

Cancer :: Green Tea with Tumor Preventive Qualities

Drinking green tea may do more than just thwart a head cold, according to research presented today at the American Association for Cancer Research Second Annual International Conference on Frontiers in Cancer Prevention Research. Green tea already is believed to help lower cholesterol and prevent heart disease, fight bacteria and dental cavities, and possibly aid weight loss. New studies are now suggesting the various potential anti-cancer benefits of the age-old beverage.
