Study design: Descriptive cross-sectional Place and duration: was carried out from February 2019 to 2021 over a period 2 years at—removed for blind review--. Methodology: All voluntary replacement donors who arrived at hospital between included time were considered analysis. Total two samples taken...

The temperature and pH dependent self-assembly of three star shaped ethylene oxide-propylene oxide (EO-PO) block copolymers (Tetronics® 304, 904 and 908) with widely different hydrophobicity was examined in aqueous solutions. Physico-chemical methods viz. viscosity, cloud point, solubilization along with thermal, scattering and spectral techniques shows strongly temperature and salt dependent s...

An enantioselective four-component reaction of a diazoketone, water, an aniline and ethyl glyoxylate in the presence of catalytic Rh2(OAc)4 and a chiral Brønsted acid was developed to efficiently produce β-hydroxy-α-amino acid derivatives in good yields with high diastereoselectivity and enantioselectivity.

Aim: To evaluate the effectiveness of four different irrigation regimes on removal of smear layer and smear plugs at the tubular apertures in the middle and apical thirds of the root canals by using Scanning Electron Microscopy(SEM). Settings and Design: In vitro material science study. Materials and methods: Twenty human mandibular first premolars were used for this study. The teeth were divid...

Serrapeptase, a proteolytic enzyme, has been used for the adjuvant treatment of many diseases. However, its fibrinolytic activity is still uncertain. Herein, serrapeptase and in vitro thrombolytic effects were investigated. The results showed that was 1295 U/mg, specific 3867 U/mg protein when toward casein 2800 U/mg. optimum temperature pH 37-40°C 9.0, respectively. At 1 mmol/L, Zn2+, Mn2+ Fe2...

During exploration for oil and gas, a technical drilling fluid is used to lubricate the drill bit, maintain hydrostatic pressure, transmit sensor readings, remove rock cuttings and inhibit swelling of unstable clay based reactive shale formations. Increasing environmental awareness and resulting legislation has led to the search for new, improved biodegradable drilling fluid components. In the ...

The administration to rats of putrescine (750 mumol/kg body wt.) caused in liver, kidney and heart an increase in putrescine at 1 h and in diamine oxidase (EC 1.4.3.6) activity within 3-6 h. An increase in spermidine was observed at 9 h in liver and at 6 h in kidney, whereas in heart there was no change. The increase in diamine oxidase activity by exogenous putrescine was prevented by the admin...
