Fructose may not be to blame for obesity

Is fructose being unfairly blamed for the obesity epidemic? Or do we just eat and drink too many calories? Researchers from St. Michael's Hospital reviewed more than 40 published studies on whether the fructose molecule itself causes weight gain.

Researchers discover new evidence on how cholesterol transfers from HDLs to LDLs

Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have found new evidence to explain how cholesteryl ester transfer protein (CETP) mediates the transfer of cholesterol from "good" high density lipoproteins (HDLs) to "bad" low density lipoproteins.

Telomerase reactivation in malignant cells after genomic instability causes cancer progression

Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.

DNA ‘nanorobot’ effectively targets cancer leaving healthy cells untouched: Study

Researchers have developed ‘nano-sized’ probes built from DNA that can seek and destroy cancer cells, leaving healthy cells untouched. These ‘nanorobots’ release their drug payload only when they reach and identify their target and are believed to improve many treatments for disease.

Autism may be evident in an infant’s brain much earlier than thought: Study

Researchers have found that autism shows tell tale signs in babies as young as 6 months old — half a year or more before parents typically begin to notice symptoms of the condition. The results shed light on the fundamental differences in the brains of autistic children and could help lead to earlier detection and treatment, says co-author Geraldine Dawson, chief science officer at Autism Speaks, which helped fund the study in today's American Journal of Psychiatry.

Modified imatinib cancer drug prevents morphine tolerance in rats

By reformulating the common cancer drug imatinib (Gleevec), researchers have eliminated morphine tolerance in rats - an important step toward improving the effectiveness of chronic pain management in patients, according to researchers at The University of Texas MD Anderson Cancer Center.

Low dose carbon monoxide therapy can prevent fetal death

Heme oxygenase-1 is essential for the growth of blood vessels in the placenta and in establishing blood flow in the umbilical cord. Too little HO-1 can lead to a restriction in the growth of the fetus and even in fetal death and miscarriage. New research published in BioMed Central's open access journal Medical Gas Research has shown that low dose carbon monoxide therapy is able to restore placental function and prevent fetal death in mice, without any detrimental effects.

Scientists discover the off signal for inflammation

Proteins, the building block for all living organisms, are the ultimate transformers - able to splice and switch roles and functions within the human body. But when these changes go wrong, diseases such as cancers and arthritis may result, says University of British Columbia researcher Chris Overall.

Nano-enabled intranasal formulation of teriparatide can treat osteoporosis

The University of Nottingham spin-out company, Critical Pharmaceuticals, has announced a -545,000 collaboration with the University to develop a nano-enabled intranasal formulation of teriparatide for the treatment of osteoporosis.

BYETTA-basal insulin combination therapy receives EMA CHMP positive opinion

Amylin Pharmaceuticals, Inc. and Eli Lilly and Company today announced that the Committee for Medicinal Products for Human Use of the European Medicines Agency has issued a positive opinion in the European Union for the expanded use of BYETTA (exenatide twice-daily) as an add-on therapy to basal insulin, with or without metformin and/or Actos (pioglitazone), for the treatment of type 2 diabetes in adults who have not achieved adequate glycemic control with these agents.

New potential strategy for KRAS-mutant colon cancers

Researchers from the Massachusetts General Hospital (MGH) Cancer Center have identified a new potential strategy for treating colon tumors driven by mutations in the KRAS gene, which usually resist both conventional and targeted treatments.

Glial cells inhibit growth of brainstem neurons

Researchers at Oregon Health & Science University have discovered that brain cells commonly thought to play a supporting role actually are critically important for the growth of brainstem neurons responsible for cardiorespiratory control. The discovery has profound implications for the prevention and treatment of SIDS (Sudden Infant Death Syndrome), the leading cause of death in children aged one month to one year.

IKK2 enzyme plays a key role in proliferation of lung cancer cells

Drugs targeting an enzyme involved in inflammation might offer a new avenue for treating certain lung cancers, according to a new study by scientists at the Salk Institute for Biological Studies.

Scientist uses GPUs to simulate inner workings of human cells

The cure for cancer comes down to this: video games. In a research lab at Wake Forest University, biophysicist and computer scientist Samuel Cho uses graphics processing units (GPUs), the technology that makes videogame images so realistic, to simulate the inner workings of human cells.

Combination of therapeutic cancer vaccines and chemotherapy shows promise

Therapeutic cancer vaccines, which stimulate the body's immune system to target and destroy cancer cells, are being used in combination with conventional chemotherapy with growing success, as described in several illuminating articles in Cancer Biotherapy and Radiopharmaceuticals, a peer-reviewed journal from Mary Ann Liebert, Inc.

Researchers identify potent regulator of sensitivity to insulin

Researchers at Washington University School of Medicine in St. Louis have identified a potent regulator of sensitivity to insulin, the hormone that controls blood sugar levels. The new findings may help scientists find better treatments for type 2 diabetes, obesity and other health problems caused by the body's inability to properly regulate blood sugar.

DC-SIGN molecule appears to play a role in fighting allergy

Scientists at The University of Nottingham have discovered a new molecule that could offer the hope of new treatments for people allergic to the house dust mite.

Chemists create new molecule that can tangle inside the DNA for up to 16 days

Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates itself, much longer than any other molecule reported.

Chemists adapt natural strategies to improve performance of DNA detectors

Over their 3.8 billion years of evolution, living organisms have developed countless strategies for monitoring their surroundings. Chemists at UC Santa Barbara and University of Rome Tor Vergata have adapted some of these strategies to improve the performance of DNA detectors. Their findings may aid efforts to build better medical diagnostics, such as improved HIV or cancer tests.

Scientists identify and describe molecular mechanism behind holoprosencephaly

Researchers of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have now identified and described a molecular mechanism underlying the most common malformation of the brain in humans. In holoprosencephaly (HPE), the forebrain (prosencephalon) is only incompletely formed.
