Anti-adenovirus activity of epiandrosterone and dehydroepiandrosterone derivatives
(Karger, 2010-05)
Background: Dehydroepiandrosterone (DHEA) exhibits a wide range of biological functions including antiviral activity. In this work, we present in vitro anti-adenovirus (AdV) activity of seven DHEA and twelve epiandrosterone ...
Preparation of activated carbons from coffee husks utilizing FeCl3 and ZnCl2 as activating agents
(Elsevier Science, 2009-06)
Ferric chloride was used as a new activating agent, to obtain activated carbons (AC) from agro industrial waste (coffee husks). This material was compared with two samples from the same raw material: one of them activated ...
Liver glucokinase: An overview on the regulatorymechanisms of its activity
(John Wiley & Sons Inc, 2011-01)
Blood glucose is the primary cellular substrate and in vivo must be tightly maintained. The liver plays a key role in glucose homeostasis increasing or decreasing glucose output and uptake during fasting and feeding. ...
Incorporation of poly(Itaconic acid) with quaternized thiazole groups on gelatin-based films for antimicrobial-active food packaging
(MDPI AG, 2021-01)
Poly(itaconic acid) (PIA) was synthesized via conventional radical polymerization. Then, functionalization of PIA was carried out by an esterification reaction with the heterocyclic groups of 1,3-thiazole and posterior ...
Progestin activation of nongenomic pathways via cross talk of progesterone receptor with estrogen receptor beta induces proliferation of endometrial stromal cells
(Endocrine Society, 2005-12)
Uterine decidualization is characterized by stromal cell proliferation and differentiation, which are controlled by ovarian hormones estradiol and progesterone. Here we report that the proliferative response of UIII rat ...
Influences of moonlight, ambient temperature, and food availability on the diurnal and nocturnal activity of owl monkeys (Aotus azarai)Influences of moonlight, ambient temperature, and food availability on the diurnal and nocturnal activity of owl monkeys (Aotus azarai)
(Springer, 2003-09)
The study of activity rhythms, their potential zeitgebers and masking factors among free-ranging primates has received relatively little attention in the past. Most primates are diurnal, a few of them nocturnal, and even ...
Some chemical composition and biological activity of northern Argentine propolis
(American Chemical Society, 2005-02)
Twenty-five samples of propolis were collected from seven different regions in northern Argentina; ethanolic extracts of propolis were prepared from all samples, and the respective samples were examined for UV absorption ...
