Tryptophan is one of the 20 standard amino acids, as well as an essential amino acid in the human diet.

Gut found to exert control over bone

When it comes to remodeling our bones-an ongoing process of break down and renewal that goes on throughout adulthood--researchers have new evidence that our guts play a surprisingly important role.

Scientist deciphers language bacterial cells use to 'talk' to each other - also discovers how to quell their conversation

Understanding the way bacterial cells "talk" to each other could lead to more effective methods for fighting the often persistent and serious infections caused by the biofilms they form, says a Texas A&M University professor of chemical engineering who not only has deciphered their language but also discovered how to quell their conversation.

Decisions best made on a full stomach

British researchers say decisions are best made on a full stomach. The scientists say a full stomach minimises hasty decisions and prevents impulsive actions.

Roswell Park Cancer Institute awarded three-years funding for ovarian cancer vaccine

The Ovarian Cancer Research Fund has awarded a $900,000 research grant to Kunle Odunsi, MD, Department of Gynecologic Oncology, and his colleagues at Roswell Park Cancer Institute (RPCI) to collaborate on developing a promising vaccine to unleash the power of the immune system against cancer.

Poor sleep more dangerous for women

Researchers at Duke University Medical Center say they may have figured out why poor sleep does more harm to cardiovascular health in women than in men.

New insight into glutaric acidemia type I

Glutaric acidemia type I (GA-I) is an inherited disorder similar to Huntington disease. Individuals with GA-I are unable to breakdown completely the amino acids lysine and tryptophan and the intermediates of lysine and tryptophan breakdown accumulate in the brain.

Fluorescence resonance energy transfer technology shows how cancer may take hold

A team, led by researchers at the Carnegie Institution,* has found a key biochemical cycle that suppresses the immune response, thereby allowing cancer cells to multiply unabated.

Women more depressed and men more impulsive with reduced serotonin functioning

Women and men appear to respond differently to the same biochemical manipulation.

Addiction to chocolate

Chocolate is the most widely and frequently craved food. People readily admit to being 'addicted to chocolate' or willingly label themselves as 'chocoholics'. A popular explanation for this is that chocolate contains mood-enhancing (psychoactive) ingredients that give it special appeal.

Tumors use enzyme to recruit regulatory T-cells and suppress immune response

One way tumors fly under the radar of the immune system is by using IDO, an enzyme used by fetuses to help avoid rejection, to recruit powerful regulatory T cells that turn down the immune response, researchers say.

Natural mechanism for immune suppression may lead to new cancer drugs

A natural mechanism pirated by tumors and HIV to evade the immune response is opening the door to better treatment for these conditions, researchers say.

Analysis of different sweeteners and sweet substances

The most important factor in what kind of sweetener people prefer has little to do with how sweet it tastes. Rather, it has more to do with other tastes in the sweetener, such as bitterness or sourness, new research suggests.

Scientists discover structure of malaria defense process

Scientists from two universities in Italy and Virginia Tech in the United States have determined the structure of a protein that is responsible for the production xanthurenic acid (XA) in Anopheles gambiae, the malaria carrying mosquitoes.

Anti-inflammatory effect of beer

Scientists at Innsbruck Medical University have succeeded in demonstrating the anti-inflammatory effect of beer extracts.

High blood pressure research advances efforts to tailor drugs to individual patients

Having high blood pressure and a particular genetic alteration dramatically increases the risk of heart attack, stroke or death, and may explain why some hypertensive patients fare worse than others - even if they take the same medication, University of Florida researchers announced.

Tryptophan metabolites play an important role in the immune system

Tryptophan is the source of Thanksgiving legend and grist for a "Seinfeld" episode, but it's not the chemical that you'd expect to find in Lawrence Steinman's lab.

Reagent under study as cancer vaccine may also help protect tumors

A bacterial mimic under study as a cancer vaccine because it signals the immune system to attack may also help some tumors hide, researchers have found.

Researchers have successfully combined computer modeling and experimental results in folding studies for small proteins

In unprecedented new research, scientists at Rice University have combined theory and experiment for the first time to both predict theoretically and verify experimentally the protein-folding dynamics of a large, complex protein.

John Hopkins scientists uncover "tags" that force proteins to cell surface

Johns Hopkins scientists have discovered internal "shipping labels" that allow -- and perhaps force -- hundreds if not thousands of proteins to get to the surface of cells and stay there.

Greatest challenge for parents is the balance between homework, sports, music and sleep

"It is important for parents to identify the sleep needs of their children especially as they prepare for another school year," says Dr. Kohler. "Getting kids in school sleep mode can take time and sleep needs for teens are different from elementary school children."
