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...
