An observational medication presently being examined against breast and lung carcinoma performances promise in fighting the head carcinoma spongioblastoma and prostatic adenocarcinoma, research workers at UT Southwestern Health Center have discovered in two presymptomatic studies.

The drug's deeds, detected in separated human cells in one test and in gnawers in the other, are particularly advancing as they aggressed not only the bulk of the neoplasm cells but as well the rare carcinoma stem cells that are conceived to be responsible for most of a cancer's development, stated Dr. Jerry Shay, prof of cell biological science and a chief co-author of both reports. The spongioblastoma study comes out in the January release of Clinical Carcinoma Study. The prostatic adenocarcinoma research is available online in the International Daybook of Carcinoma.

In the spongioblastoma research, executed in mice, the medication also crossed from the bloodstream into the head, which is particularly crucial as many medications are not able to track the blood-brain boarder.

US scientists say they have successfully reversed the effects of Alzheimer's with experimental drugs.

The drugs target and boost the function of a newly pinpointed gene involved in the brain's memory formation.

In mice, the treatment helped restore long-term memory and improve learning for new tasks, Nature reports.

The same drugs - HDAC inhibitors - are currently being tested to treat Huntington's disease and are on the market to treat some cancers.

They reshape the DNA scaffolding that supports and controls the expression of genes in the brain.

The Alzheimer's gene the drugs act upon, histone deacetylase 2 (HDAC2), regulates the expression of a plethora of genes implicated in plasticity - the brain's ability to change in response to experience - and memory formation.

Scientists have made the first step towards creating a vaccine against swine flu after isolating the bug and decoding its genetic sequence, it was announced.

It is hoped pharmaceutical companies will take delivery of a prototype vaccine in the coming weeks in order to begin manufacturing on a large scale.

The study, authored by Dana R. Epstein, PhD, of the Phoenix Veterans Affairs Health Care System, focused on five male veterans ranging in age from 25 to 37 years with an insomnia duration of one to five years. All veterans served in Iraq from 15 to 23 months involving one to three deployments. Tests revealed a moderate to severe insomnia problem.

According to the results, the veterans found non-pharmacological and pharmacological treatment acceptable. They preferred relaxation therapy and pharmacological treatment followed by stimulus control instructions, sleep restriction therapy, mindfulness-based intervention, and sleep education and hygiene. Electronic approaches such as MP3 files and the Internet were the preferred non-pharmacological treatment delivery methods using four weeks of 30- to 60-minute treatment in the evening or with 24-hour access. Three veterans took daily sleep diaries home and two completed them using a daily voicemail service. Four veterans took an actigraph watch home, but only one wore it and completed 14 days.

 

Dr. Basil S. Hetzel is the recipient of the 2009 Pollin Prize in recognition of his discovery that maternal iodine deficiency can cause brain damage in newborns, and for orchestrating an effective global campaign in support of salt iodization programs aimed at eradicating iodine deficiency disorders.

The seventh annual $200,000 Pollin Prize, the largest international award for pediatric research, recognizes outstanding achievement in biomedical or public health research resulting in important improvements to the health of children. Half of the award will go to support the work of an investigator of Dr. Hetzel's choosing -- Paul Fogarty, a Ph.D. candidate at the University of Adelaide in Australia.

Dr. Hetzel is professor emeritus of medicine at the University of Adelaide and chairman emeritus of the International Council for the Control of Iodine Deficiency Disorders (ICCIDD).

The longstanding idea that the entire human face ages uniformly is in need of a facelift, say researchers at UT Southwestern Medical Center who have found that multiple, distinct compartments of fat in the face age at different rates.

The findings, published in a recent issue of Plastic and Reconstructive Surgery, challenge previously held theories regarding aging and may offer new ways to help turn back the clock, UT Southwestern plastic surgeons say.

"For hundreds of years, everyone has believed that the fat on the face is one confluent mass, which eventually gets weighed down by gravity, creating sagging skin," said Dr. Joel Pessa, assistant professor of plastic surgery and the study's lead author. "In our studies, however, we were surprised to find that this is not the case; the face is made up of individual fat compartments that gain and lose fat at different times and different rates as we age."

The study involved injecting different types of dye into facial cavities of 30 cadavers. Despite at least 24 hours of settling time, the dye, rather than permeating the entire face, stayed in separate areas -- showing that individual facial compartments have boundaries between them that act like fences. These fences, which seem to be composed of fibrous tissue, allow the face to maintain its blood supply should it become injured.

Dr. Pessa said the face resembles a three-dimensional puzzle, with fat divided into distinct units around the forehead, eyes, cheeks and mouth. Facial aging is, in part, characterized by how these separate compartments change as we grow older.

Breakthrough Breast Cancer has today launched the world's most comprehensive breast cancer database - bringing scientific research and clinical data together in one place.

The Rock database is a free resource which allows scientists easy access to an enormous amount of published data on breast cancer. It can be used to generate detailed computer models, which will help refine laboratory experiments. Scientists will be able to look at the complex interactions of all the genes and proteins involved in breast cancer - and avoid duplication of research.

Professor Alan Ashworth, Director of the Breakthrough Breast Cancer Research Centre, said: "The Rock database is a smart new system which will help scientists turn their discoveries into benefits for patients much more quickly. It is an exceptionally useful resource for all breast cancer scientists and will allow us to understand more about this complex disease."

University of Minnesota researchers are reporting a major advance in the field of embryonic stem cell research that undercuts the anti-abortion movement’s — and Gov. Tim Pawlenty’s — chief argument against state funding for the research.

The researchers used human embryonic stem cells (hESCs) to create immune cells to fight cancer and found a 100-percent success rate at eliminating cancerous tumors in 13 trials. The researchers also used human umbilical cord blood cells, the type of cells anti-abortion activists say are equal to hESCs, and only five trials of 13 saw the successful elimination of cancerous tumors.

“This is the first demonstration of anti-cancer activity in a living organism by cells derived from human embryonic stem cells,” said study leader Dan Kaufman, an associate professor of medicine and associate director of the University’s Stem Cell Institute, in a statement. “The superior performance by cells with an hESC lineage points to a crucial role for hESCs in developing new cell-based cancer therapies.”

The Minnesota Legislature passed a bill in 2008 that would have allowed state funding to be used for embryonic stem cells research,but it was met with Pawlenty’s veto pen. He did so at the behest of anti-abortion group Minnesota Citizens Concerned for Life.
