Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

open access: yesChemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

H2O2 Activation and Alkane Oxidation by Copper Complexes With R‐dpa N3‐Tridentate Ligands: The Complex‐Based Dicopper Active Species as a Key Feature in the Efficient Alkane Oxidation

open access: yesChemistry – A European Journal, EarlyView.
Two reaction pathways, Paths 1 and 2, are involved in H2O2 activation by Cu complexes with N3‐tridentate ligands, depending on the ease of bridging structure formation. In Path 1, hydroxy radical (HO•) is formed from a hydroperoxo Cu(II) intermediate. In Path 2, a relevant complex‐based μ‐O• bridged Cu(II)2 active species is formed from a bis‐μ‐oxo Cu ...

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Future Evolution of CSMA Protocols for the IEEE 802.11 Standard

open access: yes, 2013
In this paper a candidate protocol to replace the prevalent CSMA/CA medium access control in Wireless Local Area Networks is presented. The proposed protocol can achieve higher throughput than CSMA/CA, while maintaining fairness, and without additional ...

Club Activity, Study Groups, and Academic Achievement: A Nationwide Study of Japanese Medical Students' Extracurricular Life. [PDF]

open access: yesJ Gen Fam Med
ABSTRACT Background Student involvement in extracurricular activities (ECAs) possesses multiple benefits and has attracted substantial interest in medical education. Most studies on ECAs have been conducted in Western contexts, and findings on the association between ECAs and academic achievement are mixed.
