Abstract:

The primary objective of this study is to facilitate the conversion of inorganic selenium (Se) into organic Se within plants via assimilation, subsequently feeding it to livestock and poultry to enhance healthy animal production and yield Se-enriched livestock and poultry products. Therefore, it is imperative to first investigate the impact of varying Se doses on the agronomic traits of plants as well as their forage storage and processing. This experiment investigated the effect of Se fertilizer application on the fermentation quality, chemical composition, and bacterial community of Penniset

Abstract:

Two new temperature-sensitive alleles of SEC3, 1 of 10 late-acting SEC genes required for targeting or fusion of post-Golgi secretory vesicles to the plasma membrane in Saccharomyces cerevisiae, were isolated in a screen for temperature-sensitive secretory mutants that are synthetically lethal with sec4-8. The new sec3 alleles affect early as well as late stages of secretion. Cloning and sequencing of the SEC3 gene revealed that it is identical to profilin synthetic lethal 1 (PSL1). The SEC3 gene is not essential because cells depleted of Sec3p are viable although slow growing and temperature

Abstract:

The sac culture method in combination with 6% NZ-Amine A plus 1% yeast extract was found to be the optimal condition for staphylococcal enterotoxins A (SEA) and D (SED) production. This growth condition was tested for the production of unidentified staphylococcal enterotoxins (SEs). Twenty-one Staphylococcus aureus strains that previously showed an emetic response in monkeys but were negative for any of the identified SEs when cultured by the membrane-over-agar method were grown by the sac culture method. All 21 strains produced at least one known SE. One strain produced only enterotoxin C (SE

Abstract:

The hypothesis that calcium-dependent membrane-binding proteins of the annexin family can influence intracellular membrane trafficking was tested by expressing five mammalian annexins in wild-type yeast cells (Saccharomyces cerevisiae) and in 13 yeast secretory (sec) mutants. Expression of human synexin (annexin VII) inhibited the growth of sec2, sec4 and sec15 mutants at a semi-permissive temperature. These three sec mutants are defective in the final step in the secretory pathway, the process of exocytosis. The inhibition of growth correlated with reduced viability and increased accumulation

Abstract:

The population dynamics of Staphylococcus spp. was studied during the ripening of Canastra Minas cheese at three farms located in the State of Minas Gerais, Brazil. The presence of coagulase (coa), thermonuclease (nuc), and enterotoxin (sea, seb, sec, and sed) genes was investigated in Staphylococcus strains isolated during the 60-day cheese-ripening period. The presence of the staphylococcal enterotoxins A, C, and D was also investigated in the cheese samples. Cheese samples that were matured for 0, 7, 15, 30, and 45 days presented staphylococci counts from 10³ to 10(8)cfu/g. All isolates con

AbstractThe vacuum-UV-photoelectron spectra of Se2, Se5, Se6, Se7, and Se8 have been recorded at a photon energy of h ν= 10.0 eV. The isolated molecules are examined in a supersonic molecular beam employing a new photoelectron-photoion coincidence technique. The structure of the photoelectron spectra of selenium molecules with even and odd numbers of atoms differs in a characteristic manner. While the spectra of Se6 and Se8 show one single broad band, three separated bands with different intensities are observed for Se5 and two for Se7. The spectra are compared to molecular orbital energy calc

ObjectiveIn patients with adrenal incidentalomas, hormonally active masses need to be considered, particularly cortisol-producing adenomas (CPA), aldosterone-producing adenomas, and pheochromocytomas. The screening for hypercortisolism relies on confirming excess cortisol secretion and insufficient suppression after dexamethasone. Because of its high correlation with free cortisol and its stress-free collection, salivary cortisol (SaC) may offer advantages over serum cortisol (SeC). We evaluated the value of SaC and SeC for the diagnosis of CPA.DesignComparative study between 2001 and 2006.Met

Bioactive small molecules are an invaluable source of therapeutics and chemical probes for exploring biological pathways. Yet, significant hurdles in drug discovery often come from lacking a comprehensive view of the target(s) for both early tool molecules and even late-stage drugs. To address this challenge, a method is provided that allows for assessing the interactions of small molecules with thousands of targets without any need to modify the small molecule of interest or attach any component to a surface.
