Soil drying and rewetting may alter the release and availability of aged pesticide residues in soils. A laboratory experiment was conducted to evaluate the influence of soil drying and wetting on the release of pesticide residues. Soil containing environmentally long-term aged (9-17 years) (14) C-labeled residues of the herbicides ethidimuron (ETD) and methabenzthiazuron (MBT) and the fungicide...

A meso-scale model was used to understand and describe the dynamical processes driving high ozone concentrations observed during both dry and monsoon season in monthly climatologies profiles over Lagos (Nigeria, 6.6 N, 3.3 E), obtained with the MOZAIC airborne measurements (ozone and carbon monoxide). This study focuses on ozone enhancements observed in the upper-part of the lower troposphere, ...

The liver is the major site for lactate clearance, and liver disease exacerbates lactic acidosis during orthotopic liver transplantation (OLT). This study assessed pyruvate dehydrogenase (PDH) activity in control, cirrhotic, and graft liver to test the hypotheses that 1) liver disease decreases hepatic PDH activity, 2) graft PDH activity is inhibited due to protracted ischemia, and 3) dichloroa...

Detailed studies of the properties of 3H-3-N-methylspiperone (NMSP) binding in rat and human brain homogenates were performed at 37 degrees C. In homogenates of rat striatum and frontal cortex and human caudate and frontal cortex tissues, the specific binding was found to be saturable. Rat caudate contained 33.2 pmol/gm wet-weight tissue and displayed an equilibrium dissociation constant (Kd) o...

Livers of birds collected from Japan and Korea (n = 83) were analyzed to determine the concentrations of perfluorooctanesulfonate (PFOS), perfluorooctanesulfonamide (FOSA), perfluorooctanoic acid (PFOA) and perfluorohexanesulfonate (PFHS). PFOS was found in the livers of 95% of the birds analyzed at concentrations greater than the limit of quantitation (LOQ) of 10 ng/g, wet weight. The greatest...

Ondansetron is the first of a new class of drugs, selective serotonin receptor antagonist (5 hydroxy tryptamine type 3) used as an anti emetic associated with cancer chemotherapy. Its Orally Disintegrating Tablet has been developed for patients who find swallowing difficult by freeze dried technology by RP Scherer Corporation and Scherer DDS. The aim of this study was to design a new orally dis...

In this paper, a method with the potential to rapidly produce thermoplastic polymer composite bipolar plates with improved formability and hrough-plane conductivity is described. In our earlier work, it was reported that composite bipolar plates made with graphite filled wet-lay materials xhibited excellent mechanical properties and in-plane electrical conductivity. However, the through-plane c...

The effects of short-term (5-week) exposure to wet or dry diets on fecal bacterial populations in the cat were investigated. Sixteen mixed-sex, neutered, domestic short-haired cats (mean age = 6 years; mean bodyweight = 3.4 kg) were randomly allocated to wet or dry diets in a crossover design. Fecal bacterial DNA was isolated and bacterial 16S rRNA gene amplicons generated and analyzed by 454 T...

In most ecosystems, atmospheric deposition is the primary input of mercury. The total wet deposition of mercury in atmospheric chemistry models is sensitive to parameterization of the aqueous-phase reduction of divalent oxidized mercury (Hg). However, most atmospheric chemistry models use a parameterization of the aqueous-phase reduction of Hg that has been shown to be unlikely under normal amb...

In order to ascertain possible abnormalities in somatostatin and gastrin secretion in patients with duodenal ulcer, the author compared bombesin-stimulated somatostatin and gastrin secretion by antral mucosal explants in patients with duodenal ulcer, those with atrophic gastritis and normal controls. An organ culture technique was employed. This excluded neurogenic, hormonal and circulatory inf...
