Synthesis and properties of anthracene-based cyclic π-clusters which possess two and four anthracene units are discussed. The optimal cyclization conditions were determined based on a nickel(0)-mediated reaction that afforded a cyclic anthracene dimer as the major product. Bringing two anthracene planes in close proximity in a face-to-face manner…[Read more]

The identification of food fish bearing anthropogenic contaminants is one of many priorities for Indigenous peoples living in the Arctic. Mercury (Hg), arsenic (As), and persistent organic pollutants including polychlorinated biphenyls (PCBs) are of concern, and these are reported, in some cases for the first time, for fish sampled in and around…[Read more]

Recent scientific reports and epidemiological studies have engendered mounting concerns regarding the potential human-to-human transmissibility of non-prion neurodegenerative and related diseases. This study investigated whether recipients of cadaveric pituitary hormone treatments are at increased risk of death from non-prion neurodegenerative and…[Read more]

Further analysis found differences in the variance in axial length growth (P < 0.0001) between operated and normal eyes; the variance in keratometry measurement change did not reach significance.

The standard deviation in the rate of refractive growth of normal eyes in our study is half of that found in eyes that underwent cataract…[Read more]

Analysis of 3CLpro-callophysin A complex revealed the involvement of salt bridge, hydrogen bonds, and hydrophobic interactions. callophysin A interacted with the catalytic residues (His41 and Cys145) of 3CLpro; hence it may act as a mechanism-based competitive inhibitor. Docking energy and docking affinity of callophysin A towards 3CLpro was…[Read more]
