/3-Hydroxyacyl acyl carrier protein (ACP) dehydrase has been purified 2900-fold from extracts of Escherichia coli. The enzyme catalyzes the reversible dehydration of /3-hydroxyacyl-ACP thioesters to yield specifically tram-2-enoylACP products. It is active with frans-2-enoyl-ACP thioesters of chain lengths from 4 through 16 carbon atoms. The enzyme catalyzes the hydration of cis-5frans-2-dodeca...

Tendon-to-bone healing is typically poor, with a high rate of repair-site rupture. Bone loss after tendon-to-bone repair may contribute to poor outcomes. Therefore, we hypothesized that the local application of the osteogenic growth factor bone morphogenetic protein 2 (BMP-2) would promote bone formation, leading to improved repair-site mechanical properties. Intrasynovial canine flexor tendons...

background and objectives: beta-thalassemia continues to be a cause of significant burden to the society particularly in the poorer developing countries. although sophisticated methods of screening have become available, a hunt for a cheap, rapid, objective screening method still remains elusive. thus, the objectives are to study the validity of naked-eye-single-tube-osmotic-fragility-test (nes...

The UNSW node of the Hot Carrier Solar Cell project is investigating absorbers which slow the rate of carrier cooling an essential element of a successful cell. This work includes modelling the limiting efficiencies of cells using real material properties and modelling the phonon dispersions of ordered arrays of quantum dots. The object of the latter is to determine the potential to modify the ...

Metal-halide perovskites are at the frontier of optoelectronic research due to solution processability and excellent semiconductor properties. Here we use transient absorption spectroscopy to study hot-carrier distributions in CH3NH3PbI3 and quantify key semiconductor parameters. Above bandgap, non-resonant excitation creates quasi-thermalized carrier distributions within 100 fs. During carrier...

  Purpose: To evaluate the effect of fullerene on chemical properties of naphazoline drug in   water by density functional theory (DFT) methods.   Materials and Methods: Naphazoline belongs to the imidazoline class of sympathomimetics.   The present study on naphazoline drug and its fullerene connected form were carried out using   computerized calculations of Gaussian program in b3lyp/6-31g le...

Abstract: A physics-based explicit mathematical model for the external voltage-dependent forward dark current in bulk heterojunction (BHJ) organic solar cells is developed by considering Shockley-Read-Hall (SRH) recombination and solving the continuity equations for both electrons and holes. An analytical model for the external voltage-dependent photocurrent in BHJ organic solar cells is also p...
