This protocol describes the application of the CRISPR-Trap from designing of the gene targeting strategy to validation of successfully edited clones that was validated on various human cell lines, among them human induced pluripotent stem cells (hiPSCs). The advantage of CRISPR-Trap over conventional approaches is the complete removal of any endogenous full-length transcript from the target gene. CRISPR-Trap is applicable for any target gene with no or little coding sequence in its first exon. Several human cell lines and different genes have so far been edited successfully with CRISPR-Trap.

Lattice sulfur-impregnated nanoscale zerovalent iron (S-nFe) has been recognized as a promising groundwater remediation agent. However, little information is available on its reactivity with ubiquitous extracellular antibiotic resistance genes (eARGs) in anaerobic groundwater, and how S content and speciation affect their interactions. Here, the efficient anaerobic degradation of eARGs by S-nFe (6 log within 5 min), resulting in completely inhibited transformation is showed.

Chest-to-back (CTB) tunneling of central venous catheters is a technique described in the Rapid Assessment of Vascular Access Exit Site and Tunneling Options (RAVESTO) for patients at risk for AVCR. In this retrospective review, data was collected for all venous access devices inserted using CTB tunneling in patients requiring medium to long term intravenous access for infusion or hemodialysis, who had a history of self-removing medical devices due to an alteration in mental status, or patients with severely impaired skin integrity.

In this study, porous glass with controllable layered structure was successfully prepared by the phase-separation method, with the aim to develop a high-performance high-temperature catalytic (denitrification) material. Glass compositions with different R values (n (NaO)/n (BO)) were designed based on the phase diagram of sodium borosilicate glass. The layered porous structure was obtained by heat treatment in the phase-separation temperature range and acid-leaching treatment to remove the boron-rich phase.

, also known as globe fringerush, is one of the most troublesome annual Cyperaceae weeds in dryland fields and nurseries in the Yangtze Plain, Middle and Lower in China. The chloroplast (cp) genome of , and even this genus, has not been studied yet. In this study, the feature of the cp genome of and its phylogenetic relationships has been reported for the first time.
