A carbon paste electrode (CPE) modified with a nanocomposite consisting on functionalized multiwalled carbon nanotubes, polypyrrole film (PPy) and bismuth particles is described for simultaneous determination of Pb(II) and Cd(II). The structural and surface properties of the functionalized multi...

The CC bond dissociation energy in the cyanoethynyl radical (C3N) is predicted using various coupled-cluster and composite energy methods. The singles and doubles coupled-cluster method that includes a perturbational correction for connected triple excitations, denoted CCSD(T), has been used wit...

The relationship between overweight and male fertility is well studied, still the correlation of obesity and decreased sperm quality is a subject to debate. The widely used conventional spermatological examinations alone seem to be inadequate to assess fertilization potential. Hyaluronan Binding...

Schizophrenic (SCZ) and autism (ASD) spectrum disorders share several features including social cognition impairments. In SCZ, the link between symptomatic dimensions and social cognition deficits remains unclear. The Movie for the Assessment of Social Cognition (MASC) test, available in several...

The sex of relatively primitive animals such as invertebrates is mostly determined by environmental factors and chromosome ploidy. Heteromorphic chromosomes may also play an important role, as in the ZW system in lepidopterans. However, the mechanisms of these various sex determination systems a...

The Masculinizer (Masc) gene encodes a novel lepidopteran-specific protein that controls both masculinization and dosage compensation in the silkworm Bombyx mori. The Masc protein possesses two CCCH-type zinc finger domains (ZFs), a nuclear localization signal, and an 11-amino-acid region that i...

Examination of the Mercury Atmosphere and Surface Composition Spectrometer (MASCS) photometry sequence data sets, and comparison of modeling results using both the Hapke and Kaasalainen–Shkuratov models show that these models can provide an improved photometric standardization to the MASCS'...

In this work the genotoxic effect of gossypol acetic acid (gossypol) was evaluated by determining the frequency of micronuclei and mitotic index in male mouse bone marrow cells in vivo. Bone marrow cells were collected at 24th hour after the single intraperitoneal (20, 40, and 80 μg/g) administ...

ObjectiveTo investigate the feasibility and optimal regimen of orally administration of low dose gossypol acetic acid (GA) combined with methyltestosterone (MT) plus ethinyl estradiol (EE) for contraception in males.

Gossypol has potential for widespread use as a male oral antifertility agent in humans since it appears to be highly efficacious, with reversible spermatostatic effects and minimal side effects. Furthermore, it is both inexpensive and readily available. Therefore, a thorough understanding of gos...

This study was conducted to evaluate the effect of gossypol levels on growth performance, body composition, hematology, immune response and resistance of channel catfish to Edwadsiella ictaluri challenge. A purified basal diet supplemented with 0, 300, 600, 900, 1200 and 1500 mg of gossypol from...

ObjectiveTo investigate the contraceptive mechanism of combination regimen of low-dose gossypol acetic acid (GA) with steroid hormones [desogestre/ethinylestradiol/testosterone undecanote (DSG/EE/TU)].

Gossypol, a bis-sesquiterpenoid cotton pigment, is of current interest as a male fertility-regulating agent. For the purposes of analyzing material to be studied biologically, a method is described for the analysis of gossypol by high-performance liquid chromatography. This has been used for exa...

The toxicity of gossypol has been investigated in Sprague-Dawley rats at dosages of 0, 0.5, 5.0 and 25 mg/kg per day of (±)-gossypol acetic acid. The most significant toxicological finding was marked suppression of body weight gain in rats receiving 25 mg/kg per day. Terminal studies showed 6 o...

ObjectiveTo determine whether co-administration of mixed steriod hormones can enhance the restoration of spermatogenesis damaged by gossypol acetic acid (GA).

Gossypol displays anticancer behavior and anti-fertility in males. Male rats were treated with either gossypol acetic acid (GAA) or gossypol–iron complex (GIC). Serum alanine transaminase (ALT) activity elevated of GAA. However, GIC-treated animals showed a decrease in hepatic glutathione (GSH)...

Gossypol is a yellow pigment found in the cotton plant and is of scientific and medical interest because of its anti-tumor, anti-fertility, and anti-viral properties. In order to support additional studies into the medicinal activity of gossypol, methods are needed to isolate large quantities of...

Carbonate intercalated layered Zn, ZnNi and ZnCu hydroxides were synthesized by a facile hydrothermal method for the visible light driven photocatalytic methylene blue dye degradation. The crystalline phase, surface states, optical and morphological properties were studied by using X-ray diffrac...

The nanocrystalline ZnO powders were obtained by mechanochemical treatment of zinc carbonate hydroxide. The mechanical activation was carried out in a planetary ball mill (Fritsch–Premium line–Pulversette No 7) by varying of the milling speed. The phase and structural transformation was invest...

This study is devoted to the thermal decomposition of two zinc carbonate hydroxide samples up to 400 °C. Thermogravimetric analysis (TGA), boat experiments and differential scanning calorimetry (DSC) measurements were used to follow the decomposition reactions. The initial samples and the solid...
