Mature Cells Revert Into Embryonic-like Stem Cells With Help From Physical Cues
2013-10-21 09:40:41

University of California - Berkeley Bioengineers at the University of California, Berkeley, have shown that physical cues can replace certain chemicals when nudging mature cells back to a pluripotent stage, capable of becoming any cell type in the body. The researchers grew fibroblasts cells taken from human skin and mouse ears on surfaces with parallel grooves measuring 10 micrometers wide and 3 micrometers high. After two weeks of culture in a special cocktail used to reprogram mature...

Researchers find both effectively reduce tobacco consumption among low-income smokers Researchers at the University of California, San Diego School of Medicine say high-priced cigarettes and smoke-free homes effectively reduce smoking behaviors among low-income individuals – a demographic in which tobacco use has remained comparatively high. Writing in the October 17, 2013 issue of the American Journal of Public Health, principal investigator John P. Pierce, PhD, professor and...

Food Provision Remains An Area Of Great Concern According To The 2013 Ocean Health Index
2013-10-16 06:53:48

University of California - Santa Barbara In the 2013 Ocean Health Index (OHI) –– an annual assessment of ocean health lead by Ben Halpern, a research associate at UC Santa Barbara's National Center for Ecological Analysis and Synthesis (NCEAS) and professor at the Bren School of Environmental Science & Management –– scientists point to food provision as the factor that continues to require serious attention. The OHI defines a healthy ocean as one that sustainably delivers a...

Researchers identify key proteins that help establish cell function Researchers at the University of California, San Diego School of Medicine have developed a new way to parse and understand how special proteins called "master regulators" read the genome, and consequently turn genes on and off. Writing in the October 13, 2013 Advance Online Publication of Nature, the scientists say their approach could make it quicker and easier to identify specific gene mutations associated with...

Sun And Sewage Harnessed To Produce Hydrogen Fuel Using New Device
2013-10-11 12:03:49

University of California, Santa Cruz A novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source while improving the efficiency of wastewater treatment. A research team led by Yat Li, associate professor of chemistry at the University of California, Santa Cruz, developed the solar-microbial device and reported their results in a paper published in the American Chemical Society journal ACS Nano. The hybrid device combines a...

Urine Biomarkers Show Mitochondrial Dysfunction In Diabetic Kidney Disease
2013-10-11 11:00:20

University of California, San Diego Researchers at the University of California, San Diego School of Medicine have identified 13 metabolites – small molecules produced by cellular metabolism – that are significantly different in patients with diabetes and chronic kidney disease compared to healthy controls. Twelve of the 13 metabolites are linked to mitochondrial function, suggesting that suppression of mitochondria – the powerhouses of cells – is a fundamental characteristic of...

From Lesch-Nyhan syndrome to Alzheimer's, Parkinson's and Huntington's diseases A research team, headed by Theodore Friedmann, MD, professor of pediatrics at the University of California, San Diego School of Medicine, says a gene mutation that causes a rare but devastating neurological disorder known as Lesch-Nyhan syndrome appears to offer clues to the developmental and neuronal defects found in other, diverse neurological disorders like Alzheimer's, Parkinson's and Huntington's diseases....

New Compounds Could Have Major Impact In Struggle Against Evolving Drug Resistance
2013-10-07 16:03:42

University of California - San Diego By tinkering with their chemical structures, researchers at the University of California, San Diego School of Medicine have essentially re-invented a class of popular antimicrobial drugs, restoring and in some cases, expanding or improving, their effectiveness against drug-resistant pathogens in animal models. Writing in the October 7 Early Edition of PNAS, Lars Eckmann, MD, professor of medicine, and colleagues describe creating more than 650 new...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
