The analgesic effect of continuous adductor canal block combined with popliteal plexus block for total knee arthroplasty: a randomized controlled trial.

This study aimed to confirm the hypothesis that continuous ACB (CACB) combined with a popliteal plexus block (PPB) can improve posterior knee pain, reduce nalbuphine consumption, and shorten the length of hospital stay. Patients who underwent TKA were allocated to the CACB + sham block (SHAM) or CACB + PPB groups. The primary outcome was the maximum pain score originating from the posterior knee within 4 h after TKA.

Isolating Sperm from Cell Mixtures Using Magnetic Beads Coupled with an Anti-PH-20 Antibody for Forensic DNA Analysis.

Vaginal swabs taken in rape cases usually contain epithelial cells from the victim and sperm from the assailant and forensic DNA analysis requires separation of sperm from these cell mixtures. PH-20, which is a glycosylphosphatidylinositol-anchored hyaluronidase located on the head of sperm, has important functions in fertilization. Here we describe a newly developed method for sperm isolation using anti-PH-20 antibody-coupled immunomagnetic beads (anti-PH-20 IMBs).

Construction of a library of cloned short tandem repeat (STR) alleles as universal templates for allelic ladder preparation.

Short tandem repeat (STR) genotyping methods are widely used for human identity testing applications, including forensic DNA analysis. Samples of DNA containing the length-variant STR alleles are typically separated and genotyped by comparison to an allelic ladder. Here, we describe a newly devised library of cloned STR alleles.
