The Reason For Depression in Adolescents

...l sample sizes used however they plan to do future experiments with larger numbers of individuals and to study the size of the hippocampus as depression progresses....

More Importance To Be Given To Prenatal Nutrition

...from intrauterine growth restriction. A series of experiments were conducted by researchers beginning with pregnant mice. The mice were separated into two groups of mothers and were studied for the three weeks of pregnancy. For two weeks, both groups were fully nourished. On the third week, one group of mothers...

Baby Talking Is Good For Your Child

...istinguishing the words from fluent speech. In the experiments conducted by the researchers infants were able to distinguish words from nonsense sentences after exposure to infant directed speech, but not after hearing the same in adult way of talking. The researchers are of the opinion that by learning to reco...

New ways developed to understand dyslexia

...ed affected, as claimed by previous studies. Their experiments with magnocellular (M) pathway that processes motion and brightness, and parvocellular (P) pathway that processes detail and color, have suggested that dyslexic children are equally proficient in understanding the sensations. Only when these sensatio...

Detecting DNA Damage With In-Vivo Alkaline Comet Assay

... with an acknowledged test system, the Comet assay experiments were run in parallel with an in vivo UDS test on the same hepatocyte suspensions. The results have shown that the in vivo Comet assay is a sensitive assay to detect DNA damage in the tested organs and have demonstrated the major advantage namely, the...

Environmental estrogens can cause breast cancer

...al industries. The study was carried out in mice experiments by inducing the chemical 4-nonylphenol into mice and all the 5 mice induced with 4-nonylphenol developed tumors in the breast. The study shows that exposure to environmental estrogen 4-nonylphenol increased the risk of breast cancer in mice. The stu...

Grapefruit extract effective in stomach ulcer healing

... and a COX-2 inhibitor (rofecoxib, 10 mg/kg). The experiments showed that GSE accelerated healing of ulcers involving COX-1 and COX-2 activity. Being acidic in nature people might assume that grapefruit will be harmful to ulcers bu the study proves the exact opposite. Source: American Gastroenterological Asso...

New Insight To The Role Of Peptide Signals

...ffect on the sexual behaviors of animals. In their experiments with genetically controlled mice they had showed that the effects of the endogenous alpha-MSH are quite evident in the sexual behaviors of the mice. The researchers also conclude that there is a system in which the alpha-MSH generating neurons play a...

Research Finds How Post-traumatic Stress Leads to Long-Lasting Memories

...archers have discovered what causes this following experiments on rats. This will also explain why an emotionally arousing event are remembered longer by a person than a more sedate event. Ulimately these applications will find ways to treat post-traumatic stress disorder. A research team led by UC Irvine neur...

An Anti-cancer Smart Bomb delivered using a Nanocell

... This will leave the healthy cells unharmed. The experiments currently done on mice cancer like melanoma and lung cancer have the potential of being a revolutionary form of drug delivery mechanism in cancers. The drugs that can kill cancer cells are available however they cannot be given in a high dose due to ...

New Insight Gained For Allergic Reactions

Transplant helps diabetes

... research centers in the U.S. and Europe conducted experiments on people with severe Type I diabetes by transplanting insulin-producing islet cells combined with less toxic antirejection drugs. These people are able to live normal lives without insulin. A.M. James Shapiro, MD, a Canadian surgeon, director o...

Bone tough

Angina to be treted by gene therapy

...difficult to achieve. Many pioneering gene therapy experiments have used viruses to carry genes into cells. However, this technique raises concerns over safety. The Manchester researchers are investigating an entirely new method of inserting genes, using ultrasound to "drive" them into the target cells. Early ...

Nobel Prize for Medicine

...cell lineage of C. elegans. In a series of elegant experiments that started during the 1970’s, Horvitz used C. elegans to investigate whether there was a genetic program controlling cell death. In a pioneering publication from 1986, he identified the first two bona fide “death genes”, ced-3 and ced-4. He showed ...

When it comes to health, all chocolates not the same.

...ing dark chocolate can lower blood pressure. Other experiments show cocoa flavonoids may reduce harmful blood clotting properties and decrease low-density-lipoprotein (LDL), known as the "bad cholesterol." A study was done involving adults with untreated mild hypertension who ate 3-ounce chocolate bars daily f...
