Racial disparities in head and neck cancer by biology disputed

Racial disparities in head and neck cancer by biology disputed

DETROIT – Head and neck cancer outcomes associated with race may be more closely linked to social and behavioral factors than biological differences, especially for African Americans, according to a new Henry Ford Hospital study.

Inhibiting cell signaling pathway may improve bone marrow transplant success rate

CINCINNATI – Identification of a molecular communications pathway that influences the mobilization of hematopoietic (blood) stem cells could lead to targeted therapies for improving bone marrow transplant success rates.

Nature Nanotechnology paper shows enzyme-controlled movement of DNA polymer through a nanopore

Santa Cruz, CA, USA and Oxford, UK, 27 September 2010: Research published this week in Nature Nanotechnology shows a new method of enzyme-controlled movement of a single strand of DNA through a protein nanopore. The paper, by researchers at the University of California Santa Cruz (UCSC), represents a key step towards nanopore sequencing of DNA strands.

Researchers create first molecule blocks key component of cancer genes' on-off switch

BOSTON—In the quest to arrest the growth and spread of tumors, there have been many attempts to get cancer genes to ignore their internal instruction manual. In a new study, a team led by Dana-Farber Cancer Institute scientists has created the first molecule able to prevent cancer genes from "hearing" those instructions, stifling the cancer process at its root.

Scientists release first cultivated ohelo berry for Hawaii

The first cultivar of 'ōhelo berry, a popular native Hawaiian fruit, has been released by U.S. Department of Agriculture (USDA) scientists and their university and industry cooperators.

'Ōhelo (Vaccinium reticulatum Smith) is a small, native Hawaiian shrub in the cranberry family, commonly found at high elevations on the islands of Maui and Hawaii. As people scour the landscape to harvest this delectable berry for use in jam, jelly and pie filling, they unfortunately disrupt the fragile habitats where this plant grows.

Physical limitations take a significant toll in breast cancer survivors

Physical limitations take a significant toll in breast cancer survivors

Basic physical limitations following breast cancer treatment can have far-reaching consequences that substantially affect how long a patient lives.

A biological solution to animal pandemics

EUREKA project E! 4104 ECOPROMAT has developed a novel and environmentally-friendly type of matting for use in protection against the spread of contagious animal diseases such as avian influenza, and for routine hygiene in animal and food production. Soaked with disinfectant solution, the matting can be used for disinfecting vehicle tyres, and the shoes and boots of personnel. As it is made of 100% natural fibres, it is highly absorbent to disinfectant solution; it is also fully biodegradable and therefore avoids the high disposal costs of synthetic alternatives.

Genetic clues to evolution of jaws in vertebrates unearthed by CU-led team

A half-billion years ago, vertebrates lacked the ability to chew their food. They did not have jaws. Instead, their heads consisted of a flexible, fused basket of cartilage.

This week, an international team of researchers led by a faculty member from the University of Colorado at Boulder published evidence that three genes in jawless vertebrates might have been key to the development of jaws in higher vertebrates.

The finding is potentially significant in that it might help explain how vertebrates shifted from a life of passive "filter feeding" to one of active predation.

New species of multihorned dinosaurs unearthed in Utah

"A giant rhino with a ridiculously supersized head."

"Fifteen long, pointed sideways oriented eye horns: one over the nose, one atop each eye, one at the tip of each cheek bone, and ten across the rear margin of the bony frill."

"A horned face: large horn over the nose and short, blunt eye horns that project strongly to the side."

Such phrases have been used to describe two newly discovered species of dinosaurs with looks only a mother could love. Still, they are drawing the attention and inspiring the imagination of scientists and lay people alike.

Cancer-associated long noncoding RNA regulates pre-mRNA splicing

Cancer-associated long noncoding RNA regulates pre-mRNA splicing

CHAMPAIGN, Ill. — Researchers report this month that MALAT1, a long non-coding RNA that is implicated in certain cancers, regulates pre-mRNA splicing – a critical step in the earliest stage of protein production. Their study appears in the journal Molecular Cell.

Malaria's newest pathway into human cells identified

Malaria's newest pathway into human cells identified

Development of an effective vaccine for malaria is a step closer following identification of a key pathway used by the malaria parasite to infect human cells. The discovery, by researchers at The Walter and Eliza Hall Institute in Melbourne, Australia, provides a new vaccine target through which infection with the deadly disease could be prevented.

OU research team uncovers key molecule for keeping other oral microorganisms in check

A University of Oklahoma research team has uncovered a key to arresting the growth of thrush—a type of oral yeast infection that sickens patients with compromised immune systems, diabetes and newborns as well as healthy individuals, who may contract the disease following antibiotic treatment of an illness.

Physicians beware: Cholesterol counts in kidney disease patients

To understand the health effects of high cholesterol levels, doctors first need to assess malnutrition and inflammation status in their chronic kidney disease (CKD) patients, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN).

Cilia revolution

Cilia revolution

University of Southern Mississippi scientists recently imitated Mother Nature by developing, for the first time, a new, skinny-molecule-based material that resembles cilia, the tiny, hair-like structures through which organisms derive smell, vision, hearing and fluid flow.
