Women With Anorexia Have Altered Brain Activity

People suffering from anorexia nervosa have the similar brain activities that are associated anxiety and other emotional disorders. // The study was published in the September issue of Archives of General Psychiatry. Previous evidence has suggested that alterations in the activity of serotonin (a brain chemical involved in communication between nerve cells) may contribute to the appeti...

Tooth Decay Bacteria Unaffected By Altered Biochemical Pathway

Streptococcus mutans, the bacteria responsible for causing tooth decay, are able to survive and multiply without an essential biochemical pathway that is considered// vital for the survival of normal cells. Researchers at the University of Florida have revealed that the tooth decay causing bacteria can carry out its destructive work without this pathway. "We were met with skepticism … b...

Cocaine Acts As Suppressant Not Stimulant In Genetically Altered Mice

Researchers at the Ohio State University have found that cutting off the reward pathway of cocaine on mice by genetically altering a vital target in the brain of the mice makes them shun cocaine//. Howard Gu, the study’s lead author and an associate professor of pharmacology and psychiatry at Ohio State University said that the researchers were not suggesting that humans be treated in...

Schizophrenia Complicates With Altered Receptor Activity

When analyzing the neuronal receptor activity in the postmortem brain tissue from patients with schizophrenia, researchers at the University of Pennsylvania //School of Medicine, in collaboration with scientists at the City University of New York, have found a striking dysregulation in its function. A high level of erbB4 receptor activity and reduced NMDA receptor activity were identified when th...

The Immune System May Be Altered By Certain Chemicals

A new research have found out that certain inhaled asthma medications and similar chemicals produced in our body during times of high stress // may worsen conditions like lupus, heart failures, asthma and other conditions that involve inflammation. The scientific team led by Raymond Penn, Ph.D., and Matthew Loza, Ph.D, at Wake Forest University School of Medicine, which carried out the...

Altered Sodium Channel Function Linked to Heart Failure

The results of a study, using mice and heart muscle cells from rabbits, by researchers from Georg-August-University G?ttingen, Germany, have provided// a potential molecular explanation for the abnormally rapid heartbeats known as ventricular tachyarrhythmias (VTs) that can cause the sudden death associated with heart failure. Individuals who inherit mutations in genes regulating the...

Gene-Altered Foods ? Still Not Sure

Ignorance might well be bliss for the American public. A decade after genetically altered crops were first cultivated in the continent//, Americans still remain ignorant and disinclined towards them. According to a survey sponsored by The Pew Initiative for Food and Biotechnology, the last five years have seen little change in the depth of knowledge on the subject. Says executiv...

Genetically Altered Cells Prevent Lethal Infections in Substituted Skin

Researchers have developed modified skin cells which on being added to cultured skin substitutes, may help fight off potentially lethal infections in patients with severe// burns. Cultured skin substitutes are grown in a laboratory using cells from a burn patient's own skin. These cells are cultured, expanded and combined with a spongy layer of collagen to make skin grafts that are re...

Altered Protein Structure was Found in Autism Patients

A research team led by scientists at the University of California , has discovered how particular genetic mutations affect the structure of protein complex implicated in autism . These proteins contribute to the developmental abnormalities found in children with autism. By understanding the three-dimensional structure of the normal protein, researchers can now make predictions about...

Penguins Altered Diet When Humans Began Hunting Whales and Seals

Adlie penguins living in Antarctica switched from eating fish to krill (shrimp-like marine invertebrate animals) around the time that humans began hunting seals and whales, ancient eggshell fragments reveal. According to Steven Emslie of the University of North Carolina in Wilmington, and William Patterson of the University of Saskatchewan in Saskatoon, it suggests that when human...
