Gateway Enzyme for Chemicals from Catnip to Cancer Drug Discovered 2012-12-30

By ernando Geu-Flores, Nathaniel H. Sherden

Scientists have discovered an enzyme used in nature to make powerful chemicals from catnip to a cancer drug, vinblastine. The discovery opens up the prospect of producing these chemicals cheaply and efficiently.

Computer-Navigated Total Knee Replacement Provides No Advantage Over Traditional Surgical Procedure, Study Suggests 2012-12-30

By Young-Hoo Kim, Jang-Won Park

For many years, the use of computer-assisted navigation has been touted as improving the positioning, sizing and alignment of replacement knee joints, resulting in greater durability of joints and overall improvement in patient movement. However, ne

Architecture of Rod Sensory Cilium Disrupted by Mutation 2012-12-30

By Jared C. Gilliam, Juan T. Chang

Using a new technique called cryo-electron tomography, two research teams at Baylor College of Medicine have created a three-dimensional map that gives a better understanding of how the architecture of the rod sensory cilium (part of one type of pho

Simple, Inexpensive Way to Improve Healing After Massive Bone Loss 2012-12-30

By Vaida Glatt, Micah Miller, Alan Ivkovic

Bones are resilient and heal well after most fractures. But in cases of traumatic injury, in which big pieces of bone are missing, healing is much more difficult, if not impossible. These so-called "large segmental defects" are a major cli

Need a Lot of Sleep? An Antidote for Hypersomnia 2012-12-30

By D. B. Rye, D. L. Bliwise, K. Parker

Researchers at Emory University School of Medicine have discovered that dozens of adults with an elevated need for sleep have a substance in their cerebrospinal fluid that acts like a sleeping pill.

Neural Interaction in Silence: Neurophysiologists Study Widespread Networks of Neurons Responsible for Memory 2012-12-30

By N. K. Logothetis, O. Eschenko

While in deep dreamless sleep, our hippocampus sends messages to our cortex and changes its plasticity, possibly transferring recently acquired knowledge to long-term memory. But how exactly is this done? Scientists from the Max Planck Institute for

Key Events Early in Process of Cellular Aging Defined 2012-12-30

By Adam L. Hughes, Daniel E. Gottschling

For the first time, scientists at Fred Hutchinson Cancer Research Center have defined key events that take place early in the process of cellular aging. Together the discoveries, made through a series of experiments in yeast, bring unprecedented cla

First Report of State-Level COPD Prevalence in U.S. 2012-12-30

By NIH/National Heart, Lung and Blood Institute

The age-adjusted prevalence of chronic obstructive pulmonary disease (COPD) varies considerably within the United States, from less than 4 percent of the population in Washington and Minnesota to more than 9 percent in Alabama and Kentucky. These st

Pathway Identified in Human Lymphoma Points Way to New Blood Cancer Treatments 2012-12-30

By Lori S. Hart, John T. Cunningham

A pathway called the "Unfolded Protein Response," or UPR, a cell's way of responding to unfolded and misfolded proteins, helps tumor cells escape programmed cell death during the development of lymphoma.

Aging: Scientists Further Unravel Telomere Biology 2012-12-30

By Mark Mason, Jennifer J. Wanat

Chromosomes -- long, linear DNA molecules - are capped at their ends with special DNA structures called telomeres and an assortment of proteins, which together act as a protective sheath. Telomeres are maintained through the interactions between an

Daily Steps Add Up for Midlife Women's Health 2012-12-30

By Veronica Colpani, Karen Oppermann

Moving 6,000 or more steps a day -- no matter how -- adds up to a healthier life for midlife women. That level of physical activity decreases the risk of diabetes and metabolic syndrome (a diabetes precursor and a risk for cardiovascular disease), s

Rhythmic Brain Waves: Fluctuations in Electrical Activity May Allow Brain to Form Thoughts and Memories 2012-12-30

By Timothy J. Buschman, Eric L. Denovellis

One of the biggest puzzles in neuroscience is how our brains encode thoughts, such as perceptions and memories, at the cellular level. Some evidence suggests that ensembles of neurons represent each unique piece of information, but no one knows just

Drug Resistance Biomarker Could Improve Cancer Treatment 2012-12-30

By Sidong Huang, Michael Holzel

Cancer therapies often have short-lived benefits due to the emergence of genetic mutations that cause drug resistance. A key gene that determines resistance to a range of cancer drugs has been reported in a study published by Cell Press November 21s

Uncovering Complexity in Simple Worm: Sensory Input to Motor Output in One Worm Neuron 2012-12-30

By Quan Wen, Michelle D. Po, Elizabeth Hulme

It's one of the basic tenets of biological research -- by studying simple "model" systems, researchers hope to gain insight into the workings of more complex organisms.

Genome Packaging: Key to Breast Cancer Developement 2012-12-30

By R. H. G. Wright, G. Castellano, J. Bonet

Two recent studies by CRG researchers delve into the role of chromatin modifying enzymes and transcription factors in tumour cells.

Short DNA Strands in Genome May Be Key to Understanding Human Cognition and Diseases 2012-12-30

By Hennady P. Shulha, Jessica L. Crisci

Short snippets of DNA found in human brain tissue provide new insight into human cognitive function and risk for developing certain neurological diseases, according to researchers from the Departments of Psychiatry and Neuroscience at Mount Sinai Sc

Biomarking Time: Methylome Modifications Offer New Measure of Our 'Biological' Age 2012-12-30

By Gregory Hannum, Justin Guinney

Women live longer than men. Individuals can appear or feel years younger -- or older -- than their chronological age. Diseases can affect our aging process. When it comes to biology, our clocks clearly tick differently.

Autism-Like Behaviors Reversed in Mice: New Hope for Understanding Autism 2012-12-30

By Christos G. Gkogkas, Arkady Khoutorsky

Researchers from McGill University and the University of Montreal have identified a crucial link between protein synthesis and autism spectrum disorders (ASD), which can bolster new therapeutic avenues.

Surprise Origin for Coronary Arteries Could Speed Advances in Regenerative Medicine 2012-12-30

By Bingruo Wu, Zheng Zhang, Wendy Lui

During embryonic development, the all-important coronary arteries arise from cells previously considered incapable of producing them, according to scientists at Albert Einstein College of Medicine of Yeshiva University. The research, carried out in

Kidney Tumors Have a Mind of Their Own 2012-12-30

By A. H. Girgis, V. V. Iakovlev

Kidney tumours may be smarter than we thought. New research has found there are several different ways that kidney tumours can achieve the same result -- namely, grow.
