Creating New Immune Systems for HIV Patients

August 5, 2014 2:52 pm | by Cynthia Fox | Blogs | Comments

There is good news in attempts to halt HIV by growing, in patients, new immune systems lacking a gene that led to the first—and only—cured HIV patient. Using hematopoietic (blood) stem cells possessing a CCR5 gene mutation that blocks CD4 T cell entry of HIV, Calimmune—led by Nobel Laureate David Baltimore—has, for one year, safely begun growing new immune systems in patients.

New DNA Analysis Technique Promises Speedier Diagnosis

August 5, 2014 2:01 pm | News | Comments

Researchers have achieved a technical breakthrough that should result in speedier diagnosis of cancer and various pre-natal conditions. The key discovery lies in a new tool that allows researchers to load long strands of DNA into a tunable nanoscale imaging chamber in ways that maintain their structural identity and under conditions that are similar to those found in the human body.

Obesity Paradox in Survival from Sepsis

August 5, 2014 1:51 pm | News | Comments

University of Michigan Health System researchers revealed an obesity paradox among older Americans suffering from sepsis. In a study of 1,404 Medicare beneficiaries, heavier patients were more likely to survive the life-threatening infection that can lead to a stay in a hospital’s intensive care unit.

Smart Bacteria Help Each Other Survive

August 5, 2014 1:47 pm | News | Comments

The body’s assailants are cleverer than previously thought. New research from Lund University in Sweden shows for the first time how bacteria in the airways can help each other replenish vital iron. The bacteria thereby increase their chances of survival, which can happen at the expense of the person’s health.

DNA Modifications Predict Brain’s Threat Response

August 4, 2014 1:01 pm | News | Comments

The tiny addition of a chemical mark atop a gene that is well known for its involvement in clinical depression and posttraumatic stress disorder can affect the way a person’s brain responds to threats, according to a new study.       

New Genetic Risk Markers Found in Pancreatic Cancer

August 4, 2014 12:46 pm | News | Comments

A large DNA analysis of people with and without pancreatic cancer has identified several new genetic markers that signal increased risk of developing the highly lethal disease, scientists report.               

Chili Pepper Chemical May Inhibit Gut Tumors

August 4, 2014 12:35 pm | News | Comments

Researchers report that dietary capsaicin– the active ingredient in chili peppers– produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors.   

Small RNAs in Blood May Reveal Heart Injury

August 4, 2014 12:07 pm | News | Comments

New research suggests that microRNAs may be able to relay valuable information about damage to the heart: Scientists have linked an increase in certain microRNAs circulating in the blood with injury to cardiac muscle.          

African Plant May Be Possible Treatment for Aging Brain

August 4, 2014 11:22 am | News | Comments

Scientists have discovered that a compound isolated from the plant protects cells from altered molecular pathways linked to Alzheimer’s, Parkinson’s and the neurodegeneration that often follows a stroke.

A water ban that had hundreds of thousands of people in Ohio and Michigan scrambling for drinking water has been lifted, Toledo's mayor announced Monday.                           

Ebola Vaccine Not Far Away

August 4, 2014 9:22 am | by The Associated Press | News | Comments

The nation's top infectious disease official says there's hope that a vaccine against Ebola will be available as early as next July. Dr. Anthony Fauci of the National Institutes of Health says such a preventive vaccine has been successfully tested with monkeys.

Engineering a Protein to Prevent Brain Damage from Toxic Agents

July 31, 2014 3:21 pm | News | Comments

Research at New York University is paving the way for a breakthrough that may prevent brain damage in civilians and military troops exposed to poisonous chemicals—particularly those in pesticides and chemical weapons. The research outlines the advancement in detoxifying organophosphates, which are compounds commonly used in pesticides and warfare agents.

New Way to Generate Insulin-producing Cells in Diabetes

July 31, 2014 3:20 pm | Videos | Comments

A new study has found that a peptide called caerulein can convert existing cells in the pancreas into those cells destroyed in type 1 diabetes-insulin-producing beta cells.                       

Molecule Enhances Copper’s Lethal Punch Against Microbes

Harnessing a natural process in the body that pumps lethal doses of copper to fungi and bacteria shows promise as a new way to kill infectious microbes, a team of scientists report.                   

Strict Genomic Partitioning by Biological Clock Separates Key Metabolic Functions

July 31, 2014 3:10 pm | News | Comments

Much of the liver’s metabolic function is governed by circadian rhythms—our own body clock—and UC Irvine researchers have now found two independent mechanisms by which this occurs. The study reveals new information about the body clock’s sway over metabolism and points the way to more focused drug treatments for liver disease and such metabolic disorders as obesity and diabetes.

How Is Depression Related to Dementia?

Autistic Brain Less Flexible at Taking on Tasks

July 31, 2014 9:41 am | News | Comments

The brains of children with autism are relatively inflexible at switching from rest to task performance, according to a new study. Instead of changing to accommodate a job, connectivity in key brain networks of autistic children looks similar to connectivity in the resting brain. And the greater this inflexibility, the more severe the child’s manifestations of repetitive and restrictive behaviors that characterize autism, the study found.

Dissolvable Fabric Loaded with Medicine Might Offer Faster Protection Against HIV

July 31, 2014 9:27 am | News | Comments
