We collected female greater scaup (Aythya marila) on the Yukon-Kuskokwim Delta, Alaska during two breeding seasons to determine if concentrations of 18 trace elements in livers and eggs were elevated and if hepatic concentrations correlated with body condition or affected reproductive status. Fifty-six percent, 5%, and 42% of females, respectively, had elevated hepatic cadmium (Cd: >3 microg g(...

Morphology and physiology of fish embryos undergo dramatic changes during their development until the onset of feeding, supplied only by endogenous yolk reserves. For obtaining an insight how these restructuring processes are reflected by body mass related parameters, dry weights (dw), contents of the elements carbon and nitrogen and lipid and protein levels were quantified in different stages ...

Previous research reported that concentrations of selenium in the livers of 88-95% of lesser scaup from locations in Lake Erie, Lake St. Clair, and Lake Michigan, USA were either elevated (10-33 microg/g dry weight [dw]) or in the potentially harmful range (> 33 microg/g dw). In order to determine the geographic extent of these high selenium concentrations, we collected lesser scaup in Louisian...

Mutations were induced in tissue cultured raised Bacopa monnieri (L.) plantlets by treating in vitro derived leaves with gamma rays at (γ – rays) dose rate of 0, 10, 20, 40 and 80 gray (Gy) and 0.5% of ethyl methanesulphonate (EMS) at 0, 0.5, 1.0, 1.5, 2.0 and 2.5 hours (h). Xantha mutants were observed with γ rays at 10, 20 and 40 Gy. All the leaf explants treated with 80 Gy were either necrot...

During embryogenesis of the spider crab, Hyas araneus, four developmental phases were distinguished microscopically: cleavage, gastrula, embryo differentiation, prehatching phase. Changes in fresh weight (FW), dry weight (DW), ash-free dry weight (AFDW), water, carbon (C), nitrogen (N), total lipids, proteins, carbohydrates, and respiration rates were measured in developing eggs. The percentage...

This analysis evaluated the effects of deferasirox on liver iron concentration in moderate and heavily iron-overloaded patients with β-thalassaemia from the ESCALATOR trial (n = 231). Mean liver iron concentrations (LIC) decreased significantly from 21.1 ± 8.2 to 14.2 ± 12.1 mg Fe/g dry weight (dw) at 2 yr (P < 0.001) in patients with LIC ≥ 7 mg Fe/g dw at baseline; patients with LIC < 7 mg Fe/...

Dechlorane Plus (DP) has been determined in surface sediments from three Chinese coastal bays, e.g. Jiaozhou, Sishili and Taozi Bay in North China. DP concentrations ranged from <1.2 to 187 pg g(-1) dry weight (dw) (mean: 24.7 pg g(-1)dw) in Jiaozhou Bay, <1.2 to 135 pg g(-1)dw (mean 69.9 pg g(-1)dw) in Sishili Bay and <1.2 to 66.7 pg g(-1)dw (mean: 40.4 pg g(-1)dw) in Taozi Bay, respectively. ...

Biotransformation of exogenous substrates quercetin, kaempferol and apigenin by suspension cultures Astragalus vesicarius ssp. carniolicus to their monoglycosylated derivatives was performed. The maximal enzymatic potential cells A. evaluated different concentrations substrate exposure. According quantitative ultra-high performance liquid chromatography-high resolution electrospray ionization m...

ABSTRACT Chili peppers are among the most important vegetables in world. The demand of this fruit reveals a noticeable rapid increasing, which importance is mainly due to its nutraceutical composition. These fruits rich capsaicinoids, phenolic compounds, carotenoids, and others, including vitamins. In study, comparative evaluation between two extraction methods bioactive compounds fourteen chil...

An acute toxicity experiment was conducted by intraperitoneal injection with a sublethal dose of extracted microcystins (MCs), 50 microg MC-LR (where L = leucine and R = arginine) equivalent/kg body weight (BW), to examine tissue distribution and depuration of MCs in crucian carp (Carassius carassius). Liver to body weight ratio increased at 3, 12, 24, and 48 h postinjection compared with that ...
