Knee cartilage repair success with new biomaterial

In a small study, researchers reported increased healthy tissue growth after surgical repair of damaged cartilage if they put a “hydrogel” scaffolding into the wound to support and nourish the healing process. The squishy hydrogel material was implanted in 15 patients during standard microfracture surgery, in which tiny holes are punched in a bone near the injured cartilage. The holes stimulate patients’ own specialized stem cells to emerge from bone marrow and grow new cartilage atop the bone.

‘PapGene’ test detects endometrial and ovarian cancers

Researchers have adapted the papanicolaou smear test currently used to detect cervical cancer so that it can be used to screen women for endometrial and ovarian cancers.

Repression of PTB protein in fibroblasts can convert pluripotent stem cells into functional neurons

Repression of a single protein in ordinary fibroblasts is sufficient to directly convert the cells - abundantly found in connective tissues - into functional neurons. The findings, which could have far-reaching implications for the development of new treatments for neurodegenerative diseases like Huntington's, Parkinson's and Alzheimer's, will be published online in advance of the January 17 issue of the journal Cell.

Cancer researchers solve mystery of how Chd5 protein exerts its beneficial effects

A team of cancer researchers at Cold Spring Harbor Laboratory (CSHL) has solved the mystery of how one of the most powerful of the body's natural tumor-suppressing proteins, called Chd5, exerts its beneficial effects.

Johns Hopkins develops PapGene test to diagnose ovarian and endometrial cancers

Using cervical fluid obtained during routine Pap tests, scientists at the Johns Hopkins Kimmel Cancer Center have developed a test to detect ovarian and endometrial cancers. In a pilot study, the "PapGene" test, which relies on genomic sequencing of cancer-specific mutations, accurately detected all 24 (100 percent) endometrial cancers and nine of 22 (41 percent) ovarian cancers. Results of the experiments are published in the Jan. 9 issue of the journal Science Translational Medicine.

Simple and inexpensive method to cut DNA could transform genetic medicine

A simple, precise and inexpensive method for cutting DNA to insert genes into human cells could transform genetic medicine, making routine what now are expensive, complicated and rare procedures for replacing defective genes in order to fix genetic disease or even cure AIDS.

Several genes may control body-fat responses to fast-food diets

Researchers at UCLA say it's not just what you eat that makes those pants tighter - it's also genetics. In a new study, scientists discovered that body-fat responses to a typical fast-food diet are determined in large part by genetic factors, and they have identified several genes they say may control those responses.

Researchers uncover genetic causes of von Willebrand disease

In 2006, the lab of Dr. David Ginsburg at the Life Sciences Institute put a call out for siblings attending the University of Michigan to donate blood for a study of blood-clotting disorders.

Antibiotics produce changes in microbial and metabolic patterns of the gut

A study co-led by researchers at the Universitat de València reveals that antibiotics produce changes in the microbial and metabolic patterns of the gut.

Body's sodium levels fluctuate rhythmically with 7-day and monthly cycles

Clinical pharmacologist Jens Titze, M.D., knew he had a one-of-a-kind scientific opportunity: the Russians were going to simulate a flight to Mars, and he was invited to study the participating cosmonauts.

Insect research yields insights for muscle control and nerve disorders in mammals

Working with fruit flies, Johns Hopkins scientists have decoded the activity of protein signals that let certain nerve cells know when and where to branch so that they reach and connect to their correct muscle targets. The proteins' mammalian counterparts are known to have signaling roles in immunity, nervous system and heart development, and tumor progression, suggesting broad implications for human disease research.

Link between IRGM gene and composition of human gastrointestinal bacteria

New research led by the Karolinska Institutet, Sweden and the University of Glasgow, Scotland, has identified a link between a human gene and the composition of human gastrointestinal bacteria.

SNSF-funded professor to receive 2012 National Latsis Prize

On 10 January 2013, Jacques Fellay will receive the National Latsis Prize 2012 at the Rathaus in Berne. The Swiss National Science Foundation (SNSF) is awarding the Prize to the SNSF-funded professor at EPF Lausanne in recognition of his work on the human genome and its defence mechanisms against viral diseases such as AIDS.

New research reveals a shared genetic susceptibility to epilepsy and migraine

New research reveals a shared genetic susceptibility to epilepsy and migraine. Findings published in Epilepsia, a journal of the International League Against Epilepsy (ILAE), indicate that having a strong family history of seizure disorders increases the chance of having migraine with aura (MA).
