Motherhood May Dampen Cocaine's Effects
Mother rats respond much differently to cocaine than female rats that have never given birth, according to new University of Michigan research that looks at both behavior and brain chemistry. The findings may help lay the groundwork for more tailored human addiction treatment, based on scientific understanding of how gender, hormones and life experience impact drug use. In an oral presentation at the Society for Neuroscience meeting, U-M researcher Jennifer Cummings, Ph.D...

Ependymoma Models
Experimental neurocarcinogenesis using chemical agents or certain viruses can get brain tumors; some of them have been considered classically as ependymomas according to their histological aspects. However, it is now accepted that these tumors do not meet a clear criteria to be considered as ependymoma models. Xenografts of human ependymomas in nude mouse are most useful models, but they have the disadvantage that the absence of host immune response may mask important aspects currently considered in the biology of brain tumors.

Cleaner fracking
(American Chemical Society) Technology that opened a wealth of new natural gas resources in the US is producing millions of gallons of dirty water -- enough from one typical gas well to cover a football field to a depth of 9-15 feet. Cleaning up that byproduct of "fracking" is the topic of the cover story of the current issue of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.

New advance could help soldiers, athletes, others rebound from traumatic brain injuries
(American Chemical Society) A potential treatment for traumatic brain injury (TBI), which affects thousands of soldiers, auto accident victims, athletes and others each year, has shown promise in laboratory research, scientists are reporting. TBI can occur in individuals who experience a violent blow to the head, a gunshot injury or exposure to an explosion. The report on TBI, which currently cannot be treated and may result in permanent brain damage or death, appears in the journal ACS Nano.

UC Davis researchers clarify process controlling night vision
(University of California - Davis Health System) On the road at night or on a tennis court at dusk, the eye can be deceived. Vision is not as sharp as in the light of day, and detecting a bicyclist on the road or a careening tennis ball can be tough. New research reveals the key chemical process that corrects for potential visual errors in low-light conditions. Understanding this fundamental step could lead to new treatments for visual deficits, or might one day boost normal night vision to new levels.

The Chemical Identification and Analysis of Aspergillus nidulans Secondary Metabolites
Filamentous fungi have long been recognized to be a rich source of secondary metabolites with potential medicinal applications. The recent genomic sequencing of several Aspergillus species has revealed that many secondary metabolite gene clusters are apparently silent under standard laboratory conditions. Several successful approaches have been utilized to upregulate these genes and unearth the corresponding natural products. A straightforward, reliable method to purify and characterize new metabolites therefore should be useful. Details are provided herein on the cultivation of Aspergillus nidulans and the LC/MS analysis ...

There is no consensus on which media are the optimal for metabolite production, but a series of useful and effective media and incubation conditions have been listed here. Chemically well-defined media are suited for biochemical studies, but in order to get chemical diversity expressed in filamentous fungi, sources rich in amino acids, vitamins, and trace metals have to be added, such as yeast extract and oatmeal.
