Discovery of molecular link between Alzheimer's disease and amyloid plaques

According to estimates there are 85,000 Alzheimer patients in our country and approximately 20,000 new cases every year. This spectacular increase is due to the increasing ageing population. Unfortunately it is still unclear precisely which ageing process forms the basis of this spectacular rise in the occurrence of the disease.

Discovery of protein that helps predict prostate cancer survival

An Oregon Health & Science University Cancer Institute researcher has identified a protein that is a strong indicator of survival for men with advanced prostate cancer. The C-reactive protein, also known as CRP, is a special type of protein produced by the liver that is elevated in the presence of inflammation.

Link found between relational victimization in adolescence and depression and anxiety in early adulthood

Spreading rumors and gossiping may not cause bruises or black eyes, but the psychological consequences of this social type of bullying could linger into early adulthood, a new University of Florida study shows.

Red colobus monkeys in Uganda found to harbor antibodies to an unknown orthopoxvirus

Researchers report this month that red colobus monkeys in a park in western Uganda have been exposed to an unknown orthopoxvirus, a pathogen related to the viruses that cause smallpox, monkeypox and cowpox. Most of the monkeys screened harbor antibodies to a virus that is similar - but not identical - to known orthopoxviruses.

Estimating mortality risk reduction and economic benefits from controlling ozone air pollution

Short-term exposure to current levels of ozone in many areas is likely to contribute to premature deaths, says a new National Research Council report, which adds that the evidence is strong enough that the U.S. Environmental Protection Agency should include ozone-related mortality in health-benefit analyses related to future ozone standards.

Environmental factors weigh heavily in modulating gene expression in humans

Score one for the nurture side of the nature vs. nurture debate, as North Carolina State University geneticists have shown that environmental factors such as lifestyle and geography play a large role in whether certain genes are turned on or off.

Scientists solve mystery about critical mechanism of gene expression

Although letters representing the three billion pairs of molecules that form the "rungs" of the helical DNA "ladder" are routinely called the human "genetic code," the DNA they comprise transmits traits across generations in a variety of ways, not all of which depend on the sequence of letters in the code.

Mechanism discovered that can send cells on the road to cancer

Using a common virus as a tool for investigating abnormal cell proliferation, a team led by scientists at Cold Spring Harbor Laboratory (CSHL) has succeeded in clarifying an intricate series of biochemical steps that shed light on a way that cancer can begin.

Siblings may be to blame for low grades, bad behavior

We all know the story of a man named Brady and the group that somehow formed a family. But if the iconic '70s sitcom about a "blended" family reflected reality, the Brady Bunch likely would have been dealing with much more than silly sibling squabbles.

New advance in use of oncolytic viruses as novel cancer treatments

Combining a herpes virus genetically altered to express a drug-enhancing enzyme with a chemotherapy drug effectively and safely reduced the size of highly malignant human sarcoma grafted into mice.

New understanding of how exercise impacts the heart

For the first time researchers are beginning to understand exactly how various forms of exercise impact the heart. Massachusetts General Hospital (MGH) investigators, in collaboration with the Harvard University Health Services, have found that 90 days of vigorous athletic training produces significant changes in cardiac structure and function and that the type of change varies with the type of exercise performed.

NIAID tackles drug-resistant tuberculosis

Tuberculosis (TB) has long been one of the world’s great killers. Now, forms of drug-resistant TB--multidrug (MDR) and extensively drug-resistant (XDR)--are occurring at an ominous and accelerating rate. To help in the fight against drug-resistant TB, the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, has formulated an MDR and XDR TB research agenda.

Discovery of new way to prevent cardiac fibrosis

In a study that points to a new strategy for preventing or possibly reversing fibrosis - the scarring that can lead to organ and tissue damage - researchers at the University of California, San Diego School of Medicine have determined that a molecule called Epac (Exchange protein activated by cAMP1), plays a key role in integrating the body’s pro- and anti-fibrotic response.

An atomic view of protein behind hereditary cerebral amyloid angiopathy

For the first time, researchers have peered deeply at the atomic level into the protein that causes hereditary cerebral amyloid angiopathy (CAA) -- a disease thought to cause stroke and dementia.

Black women less likely to develop urinary incontinence than white women

The good news for black women: They have less than half the chance of developing urinary incontinence as do white women, according to a new study from the University of Michigan Health System.

Number of HIV-positive state and federal inmates drops

Between 2005 and 2006 the number of state and federal prisoners who were HIV-positive decreased 3.1 percent -- from 22,676 to 21,980 inmates, according to a report by the Justice Department's Bureau of Justice Statistics (BJS). Another BJS report estimated that 44 percent of state inmates and 39 percent of federal inmates reported a current medical problem other than a cold or a virus.

Lumbar supports for prevention and treatment of low back pain

Lumbar or lower back supports - those large belts that people wear around their waists when they lift or carry heavy objects - are not very useful for preventing low back pain, according to a new systematic review.

Second annual Johns Hopkins NanoBio Symposium to focus on cancer

An estimated 600 experts on nanobiotechnology-a science that develops tools and machinery at the scale of one-billionth of a meter-are expected to attend the second annual Johns Hopkins NanoBio Symposium, May 1-2, 2008.
