To examine the effects of ingested snakeweed foliage (SW) on male fertility and reproduction, SW collected at prebloom stage was dried, ground, and mixed with ground commercial rat feed (CRF) as 0, 12.5, and 25% of total diets. Male rats fed SW for 20 d impregnated females as successfully as did dietary controls, but males fed 12.5 or 25% SW for 40 d had seemingly impaired fertility and apparen...

Semantic Web (SW), commonly regarded as the next generation of the Web, is an emerging vision of the new Web from the Knowledge Representation and the Web communities. The Formal Methods community can also play an important role to contribute to SW development. Reasoning and consistency checking can be useful at many stages during the design, maintenance and deployment of SW ontology. However t...

Element concentrations were measured by X-ray microanalysis in seawater (SW) compartments and mucocytes in bulk, frozen-hydrated preparations of the scleractinian coral Galaxea fascicularis. Quantitative X-ray microanalysis of polyps sampled in the daytime revealed that concentrations of the elements Na, S, K and Ca were all significantly higher in a thin (10-20 micro m) external SW layer adjac...

Gradient-corrected density functional theory (DFT) computations were performed to investigate the geometry, electronic property, formation energy, and reactivity of Stone-Wales (SW) defects in zigzag-edge and armchair-edge boron nitride nanoribbons (BNNRs). The formation energies of SW defects increase with an increase in the widths of BNNRs and are orientation-dependent. SW defects considerabl...

Silkworm antitrypsin (sw-AT) isolated from larval hemolymph was limitedly digested by Achromobacter lysylendopeptidase, alpha-chymotrypsin, subtilisin BPN', subtilisin Carlsberg, papain, or Pseudomonas elastase. Each proteinase could cleave specific site(s) around the reactive site identified for the reaction of sw-AT and bovine trypsin. Among these proteinases, only subtilisin BPN' was inhibit...

The gas push-pull test (GPPT) is a single-well gas-tracer method to quantify in situ rates of CH4 oxidation in soils. To improve the design and interpretation of GPPT field experiments, gas component transport during GPPTs was examined in abiotic porous media over a range of water saturations (0.0 < or = Sw < or = 0.61). A series of GPPTs using He, Ne, and Ar as tracers for CH4 were performed a...

BACKGROUND Axillary hair can influence the development of underarm odor in men. OBJECTIVE To compare different hair removal procedures and their impact on the effectiveness of standard soap washing (SW) in reducing male axillary odor. METHODS The axillae of healthy Caucasian males (N = 30; 18-48 years of age) were randomized in a non-crossover, split body design. Two of four axillary treatm...

We investigated the salinity-dependent expression dynamics of seven aquaporin paralogs (aqp1a, aqp3a, aqp7, aqp8ab, aqp10a, aqp10b and aqp11a) in several tissues of euryhaline Japanese medaka (Oryzias latipes). All paralogs except aqp7 and aqp10a had a broad tissue distribution, and several were affected by salinity in both osmoregulatory and non-osmoregulatory tissues. In the intestine, aqp1a,...

Swine appear to be a key species in the generation of novel human influenza pandemics. Previous pandemic viruses are postulated to have evolved in swine by reassortment of avian, human, and swine influenza viruses. The human pandemic influenza viruses that emerged in 1957 and 1968 as well as swine viruses circulating since 1998 encode PB1 segments derived from avian influenza viruses. Here we i...
