The performances of the optimized tree-type cylindrical-shaped nanoporous fltering membranes with six or seven branch pores in each pore tree are analytically studied. The radius Rb,1 of the branch pore for fltration is normally on the 1 or 10 nm scales. The larger trunk pore is for ...

OBJECTIVE To determine the impact of doctors' communication style and doctor-patient race concordance on UK African-Caribbeans' comfort in disclosing depression. METHODS 160 African-Caribbean and 160 white British subjects, stratified by gender and history of depression, participated in simulated depression consultations with video-recorded doctors. Doctors were stratified by black or white r...

     Lipases catalyze hydrolysis and synthesis of triacylglycerols. These enzymes,especially the microbial ones, have wide commercial and industrial usage. Bacillus subtilis <span style="color: ...

The three-dimensional structure of pectate lyase E (PelE) has been determined by crystallographic techniques at a resolution of 2.2 A. The model includes all 355 amino acids but no solvent, and refines to a crystallographic refinement factor of 20.6%. The polypeptide backbone folds into a large right-handed cylinder, termed a parallel [beta] helix. Loops of various sizes and conformations protr...

      In this work we sought to determine whether vesicles (liposomes/niosomes) were able to enhance finasteride concentration in the dermis layer, including the pilosebaceous units (PSU). Such enhancement could be beneficial in the treatment of some androgen-related skin disorders. Hamster flank skin was used to study  <span styl...

Low transverse sacral fractures are rare, with only two published reports regarding their surgery. The complication associated with surgery for sacral fractures is the prominence of implants. In addition, screw fixation below S3 is impractical. We performed posterior sacral fixation using S2 alar iliac (S2AI) screws and sacral sublaminar wires for low transverse sacral fractures. Case 1 was 65-...

In recent years, the notion that computers and robots will attain superhuman levels of intelligence in the next few decades, ushering in a new “posthuman” era in evolutionary history, has gained widespread attention among technology enthusiasts, thanks in part to books such as Ray Kurzweil’s The Singularity Is Near. This paper describes an introductory-level AI course designed to examine this i...
