The catalytic potential of tin(II)acetate, tin(IV)acetate, dibutyltin-bis-acetate and dioctyl tin-bis-acetate was compared based on polymerizations L-lactide conducted in bulk at 160 or 130°C. With SnAc2 low-Lac/Cat ratios (15/1–50/1) were studied linear chains having one acetate carboxyl end group almost free cyclics obtained. Higher monomer/catalyst lower temperatures favored formation cycles...

background & aim: sexual health is an essential element of quality of life, affecting both physical and psychological domains. hormones used in contraceptive methods have contradictory effects on sexual function. in this study, we aimed to compare sexual function in women using combined oral contraceptives (coc) and depot medroxyprogesterone acetate (dmpa), referred to healthcare centers affili...

results long-term exposure to lead acetate caused histopathology effects including dilatation, congestion, nuclei heterochromatic effects, increase in diameter of renal tubules and urinary barrier thickness in rabbit renal tissue. conclusions quantitative and qualitative results of long-term lead acetate exposure showed many histopathology side-effects, especially in the urinary barrier. materi...

In order to increase the productivity of human interleukin-2 (IL-2) as a model protein in the recombinant E.coliBL21 (DE3), the effect of magnesium acetate and manganese acetate was studied based on full factorial design experiments magnesium acetate and manganese acetate and their interaction exhibited an increasing effect on IL-2 expression level upto 25.24%, 16.80% and 23.30%, respective...

  In this study, the effects of lead acetate on two types of pain (nociception and inflammation) induced by formalin and its interaction with the opioid system and morphine-induced analgesia were examined. Male albino mice weighing 22-27 g were used in the experiments. Morphine was administered subcutaneously 30 minutes before formalin injection. Lead acetate was intraperitoneally administered ...

Ferulago angulata Boiss. known in Iran as Chavir, has some bioactive compounds having antioxidant activity. Because of its antioxidant activities, it sounded Chavir extract can be a good candidate for finding chemopreventive agents having inductive apoptosis properties on cancer cells. In this study, the cytotoxic effects and proapoptotic activities of Chavir's leaf and flower extracts were inv...

We report the isolation of several coumarins and the stereochemical assessment of some pyranocoumarins, as well as the antibacterial and antioxidant activities of the three most abundant ones (grandivittin, agasyllin and aegelinol benzoate) isolated from the roots of Ferulago campestris collected in Sicily and of the hydrolysis product (aegelinol). Aegelinol and agasyllin showed antibacterial a...
