Association between rs6493497 and rs936306 polymorphisms and depression susceptibility in the Chinese population.

The gene encodes the key aromatase for estrogen biosynthesis, and this study aimed to explore the relationship between rs6493497 and rs936306 polymorphisms and depression risk. rs6493497 and rs936306 genotyping was performed on 502 depression patients and 504 healthy controls. In the general population, no significant association was observed between the rs6493497 variant and depression, whereas that rs936306 variant significantly reduced depression risk in the recessive model.

Sorption and bioreduction of hexavalent uranium at a military facility by the Chesapeake Bay.

Directly adjacent to the Chesapeake Bay lies the Aberdeen Proving Ground, a U.S. Army facility where testing of armor-piercing ammunitions has resulted in the deposition of >70,000 kg of depleted uranium (DU) to local soils and sediments.

Sequential chemical oxidation and aerobic biodegradation of equivalent carbon number-based hydrocarbon fractions in jet fuel.

Remediation of petroleum mixtures is complicated by the differing environmental degradabilities of hundreds of individual hydrocarbons in the mixtures. By grouping the individual hydrocarbons into a few fractions based on equivalent carbon number (EC), the present study examined the chemical and biological degradation of the fractions. With or without prechemical oxidation (25 days) by three oxidants (KMnO4, H202, MgO2), sterile and live microcosms were constituted with aquifer samples for aerobic biodegradation (134 days) of JP-4 jet fuel.
