University of Delaware research to shed light on osteoporosis

Ten million people in the United States are estimated to already have bone diseases, and almost 34 million more are estimated to have low bone mass, putting them at increased risk for osteoporosis, according to the National Osteoporosis Foundation.

Stem cells from cloned monkeys - a breakthrough or an ethical nightmare?

In an important breakthrough scientists in the United States have cloned monkey embryos to create embryonic stem cells.

Viral infection affects important cells' stress response

Viral infection disrupts the normal response of mammalian cells to outside deleterious forces, cleaving and inactivating a protein called G3BP that helps drive the formation of stress granules, which shelter the messenger RNAs that carry the code for protein formation, said researchers from Baylor College of Medicine in Houston.

Cultural habits influence oral cancers

Clinicians from the USC School of Dentistry unravel connection between the incidence of oral cancer and race and ethnicity-- as part of first epidemiological study of oral cancer in California.

Why are males in evolutionary overdrive even though they have essentially the same genes as females?

The observation that males evolve more quickly than females has been around since 19th century biologist Charles Darwin noted the majesty of a peacock's tail feather in comparison with the plainness of the peahen's.

Scientists zero in on the cellular machinery that enables neurons to fire

Toy robots with removable body parts - you probably had fun swapping their heads, imagining how it would affect their behavior. Scientists supported by the National Institutes of Health have been performing similar experiments on ion channels - pores in our nerve cells - to sort out the channels' key functional parts.

Compound of milk thistle shows anti-cancer effects

Recently, scientists demonstrated the anti-cancer effects of silibinin, a major biologically active compound of milk thistle. Being widely used as a folk remedy for liver diseases, milk thistle is safe and well-tolerated, and it protects the liver from drug or alcohol-related injury.

Discovery of key mechanism in bacterial communication

A team of Princeton scientists has discovered a key mechanism in how bacteria communicate with each other, a pivotal breakthrough that could lead to treatments for cholera and other bacterial diseases.

Human embryonic stem cells derived from preimplantation genetically diagnosed embryos

A human stem cell line derived from embryos that were identified by preimplantation genetic diagnosis (PGD) to carry the mutation for fragile X syndrome has provided an unprecedented view of early events associated with this disease.

Head-to-head comparison of Forteo and Fosamax

The osteoporosis drug Forteo works better than Fosamax to strengthen bones in arthritis patients with prednisone-induced osteoporosis, according to a new study from a researcher at the University of Alabama at Birmingham (UAB.)

New explanation for how regulatory networks of genes evolved

When ancient retroviruses slipped bits of their DNA into the primate genome millions of years ago, they successfully preserved their own genetic legacy.

New understanding of how bacteria survive in hostile environments

Using an innovative device with microscopic chambers, researchers from four institutions, including Johns Hopkins, have gleaned important new information about how bacteria survive in hostile environments by forming antibiotic-resistant communities called biofilms.

Telomerase enzyme structure provides significant new target for anti-cancer therapies

Inappropriate activation of a single enzyme, telomerase, is associated with the uncontrollable proliferation of cells seen in as many as 90 percent of all of human cancers. Since the mid-1990s, when telomerase was first identified in human tumors, scientists have eyed the enzyme as an ideal target for developing broadly effective anti-cancer drugs.

GPRC5A gene found to be a tumor-suppressor for lung cancer

The GPRC5A gene, which is under-expressed in human lung cancer cells, suppresses lung tumors in mouse models and could provide a key to attacking lung cancer in humans, researchers at The University of Texas M. D. Anderson Cancer Center report in the Nov. 21 edition of The Journal of the National Cancer Institute.

PET scans useful for some cancer treatment, but how do patients fare?

Positron emission tomography or PET scans can help clinicians diagnose and treat some cancers, but it is not clear yet whether the imaging technology helps people with cancer live longer and healthier lives, according to a comprehensive review by the U.K. National Health Service.

La Jolla Institute for Allergy & Immunology to perform study on allergy molecular causes

A major study that will provide a new window into understanding and potentially treating allergies will be conducted by the La Jolla Institute for Allergy & Immunology (LIAI) under a $5 million federal contract.

Real-time 3-D analysis of breast cancer biopsies

A sophisticated microscope that offers a “real-time” 3-D analysis of tissue samples might, in the future, reduce the number of needle biopsies traditionally needed from women suspected of having breast cancer, according to recent research published at Georgetown University Medical Center's Lombardi Comprehensive Cancer Center.

To get more out of your next cup of tea, just add juice

A study found that citrus juices enable more of green tea's unique antioxidants to remain after simulated digestion, making the pairing even healthier than previously thought.

Implanting myoblasts may improve severe urinary incontinence

Estimates are that up to 70 million people worldwide may be suffering from severe urinary incontinence. A major cause of urinary incontinence is a deficiency of the urethral sphincter muscle, often associated with trauma during child birth, resulting from prostate surgery, or due to aging.
