The effects of the environmental estrogen 17alpha-ethinylestradiol (EE) on mixed populations of 90 individual Gammarus pulex were examined following a 100-d exposure in a flow-through system. Counts of total animal numbers revealed that, in all treatment groups, population size dramatically increased due to recruitment, with neonate and juvenile gammarids the most abundant. At concentrations of...

nutritive value of ephedra (ephedra intermedia) was evaluated through determination of chemical compositions, in situ degradability and in vitro gas production techniques using three permanently fistulated adult baluchi sheep. the samples were harvested during the late spring from rangeland in north of khorasan razavi province. the rate of gas production and degradability characteristics of dry...

BACKGROUND Eating behavior affects weight and thus the development of obesity. Studies on the effect of occupational burnout (exhaustive fatigue, cynicism, and lost occupational self-respect caused by chronic work stress) on eating behavior are lacking. OBJECTIVE The objective was to investigate associations between occupational burnout, eating behavior, and weight among working women. DESI...

The physiological mechanisms that underlie the metabolic benefits of breaking up sedentary behavior (SB) have yet to be determined. The purpose of this study is to compare energy expenditure (EE) and muscle activation (MA) responses to sitting and four SB alternatives in younger and older adults. Twenty-two adults, grouped by age (21-35 and 62-76 years), completed five randomly ordered 20 min t...

Background: Diabetes is a metabolic disorder that in long period can damage the testis and reduce the semen quality. Therefore, it can impair the male fertility potential. Recently, different herbal therapeutic treatment for protection of diabetes and its pathologic effects have been used. The aim of current study is to evaluate the protective effect of Equisetum arvense extract (EE) on in vitr...

OBJECTIVE To analyze 6 different types of visible anterior occlusion, exclusive of extraoral facial features, in terms of their esthetic appeal, as perceived by 91 randomly selected adult laypersons with different levels of education in Lima, Peru. METHODS Photographic images of 3 examples of each occlusion type (open bite [OB], deep bite [DB], crossbite [CB], end-to-end bite [EE], crowded bi...

Erlotinib (ELT) as a small molecule with poor solubility, poor bioavailability, and instability in gastrointestinal environment, has been considered as a therapeutic agent for Non-Small-Cell Lung Cancer (NSCLC) therapy through oral administration. In the present study, ELT-liposome and ELT-NLCs were successfully prepared and characterized by assessment of the particle size, zeta potential (ZP),...

nutritive value of winterfat forage (eurotia ceratoides) was evaluated through chemical composition, in situ degradability and in vitro gas production techniques using three permanently fistulated adult baluchi sheep. the cp, ndf, adf, ash, ee and nfc contents of winterfat forage was 19.4, 54.5, 41.6, 9.0, 1.4 and 15.7%, respectively. the leaves had highest cp (27.9%dm) and lowest ndf (40.7%dm)...
