Mouse embryos with the human enzyme CYP2C19 in the brain develop a smaller hippocampus and anxiety-like behaviour as adults. The results of this new study, which is published in the journal Molecular Psychiatry, agree in principle with earlier genetic findings in humans, and can improve...
Two new studies published in Nature recently reveal the structure and mechanism of an enzyme called cGAS that detects DNA found in the wrong place inside mammal cells and triggers an immune response. The researchers believe their findings open avenues for developing new cancer and autoimmune...
The first symptoms of major depression may be behavioral, but the common mental illness is based in biology — and not limited to the brain. In recent years some studies have linked major, long-term depression with life-threatening chronic disease and with earlier death, even after lifestyle risk...
cause this? Basically, I went to the hospital and my liver readings from my blood came back really high on all, all plus 400 except total protein which was 82, my AST was 695, my ALT, was 560, can anyone tell me why? or what they actually mean?
I did a lab aimed to determine the Aspartate Aminotransferase activity in human plasma.
We measured the absorbance of different concentrations of NADH and from this worked out the extinction coefficient of 5.713 (3dp)
We also measured absorbance of a control sample and 2 patient samples. The...
Studied for decades for their essential role in making proteins within cells, several amino acids known as tRNA synthetases were recently found to have an unexpected - and critical - additional role in cancer metastasis in a study conducted collaboratively in the labs of Karen Lounsbury, Ph.D...
Just like a comic book super hero, you could say that the enzyme superoxide dismutase (SOD1) has a secret identity. Since its discovery in 1969, scientists believed SOD1's only role was to protect living cells against damage from free radicals. Now, researchers at the Johns Hopkins Bloomberg...
Researchers at the Mayo Clinic in Florida have discovered that an enzyme called PRSS3, or mesotrypsin, may help drive aggressive prostate cancer. Although they don't believe it is the only factor, they suggest it offers a new target for treatment, and have themselves developed a prototype...
Scientists have discovered an enzyme used in nature to make powerful chemicals from catnip to a cancer drug, vinblastine. The discovery opens up the prospect of producing these chemicals cheaply and efficiently. They are produced naturally by some plants such as the medicinal Madagascar...
University of Iowa researchers have previously shown that an enzyme called CaM kinase II plays a pivotal role in the death of heart cells following a heart attack or other conditions that damage or stress heart muscle. Loss of beating heart cells is generally permanent and leads to heart...
Neutrophil granulocytes comprise important defences for the immune system. When pathogenic bacteria penetrate the body, they are the first on the scene to mobilise other immune cells via signal molecules, thereby containing the risk. To this end, they release serine proteases - enzymes that cut...
Male and female mice engineered to express the inflammatory enzyme IKKbeta in their fat tissue ate more but gained less weight. They burned sugar and fat more effectively than mice who were left unaltered. The research may shed light on how obesity and inflammation affect insulin resistance and...
Brain damage due to birth asphyxia where the brain is starved of oxygen around the time of delivery is normally treated by cooling the infant, but this only helps one baby in nine. New research from the Sahlgrenska Academy at the University of Gothenburg, Sweden, could now pave the way for new...
Scientists this month reported the molecular structural basis for severe head deformities and ambiguous sex organs in babies born with Antley-Bixler syndrome accompanied by an enzyme deficiency. The team, composed of researchers from The University of Texas Health Science Center San Antonio, the...
Pancreatic cancer researchers at Thomas Jefferson University have shown, for the first time, that blocking a receptor of a key hormone in the renin-angiotensin system (RAS) reduces cancer cell growth by activating the enzyme AMPK to inhibit fatty acid synthase, the ingredients to support cell...
The enzyme is called Diastase (an amylase) <-- What does amylase mean?
Introduction should cover...
Function of enzymes
Effect of diastase on starch
Sensitivity of enzymes to varying factors
Broccoli can significantly reduce your risk of developing cancers if you don't destroy the enzyme myrosinase - you can only do this effectively by steaming the vegetable lightly. Overcook it and the health benefits will be considerably undermined, researchers from the University of Illinois...
relationship between this fact and? a. Heat-resistant bacteria in hot springs can initiate the polymerase chain reaction.
b, Heat-resistant enzymes can be extracted from heat-resistant bacteria growing in Yellowstone National Park hot springs.
c. Hot springs vary in temperature just like...
New Clue In Leukemia Mystery: Researchers Identify "Poison" Employed By Deadly Enzyme
There is new hope for people with acute myelogenous leukemia (AML), a fast-growing cancer of the blood and bone marrow. Research led by Weill Cornell Medical College and published today in the online edition...
Most treatment for advanced head and neck cancer requires chemotherapy with a drug called cisplatin, an inorganic platinum agent that inhibits cell growth. A substantial number of patients do not respond well to this therapy, but oncologists are unable to prescribe alternative agents because...
