Genome-wide association study of varenicline-aided smoking cessation.

Introduction: Varenicline is an α4β2 nicotinic acetylcholine receptor partial agonist with the highest therapeutic efficacy of any pharmacological smoking cessation aid and a 12-month cessation rate of 26%. Genetic variation may be associated with varenicline response, but to date no genome-wide association studies of varenicline response have been published.

Methods: In this study, we investigated the genetic contribution to varenicline effectiveness using two electronic health record-derived phenotypes.

Dysregulation of the NLRP3 Inflammasome and Promotion of Disease by IL-1β in a Murine Model of Sandhoff Disease.

Sandhoff disease (SD) is a progressive neurodegenerative lysosomal storage disorder characterized by GM2 ganglioside accumulation as a result of mutations in the gene, which encodes the β-subunit of the enzyme β-hexosaminidase. Lysosomal storage of GM2 triggers inflammation in the CNS and periphery. The NLRP3 inflammasome is an important coordinator of pro-inflammatory responses, and we have investigated its regulation in murine SD.

Suture tapes show superior biomechanical properties and greater meniscal healing compared to conventional sutures in posterior meniscal root tear repairs: A systematic review.

Purpose: This study aims to perform a systematic review to determine whether ultra-high molecular weight polyethylene (UHMWPE) tapes have superior biomechanical properties compared to conventional sutures in posterior meniscal root tear (PMRT) repairs, and whether this translates into superior clinical outcomes.

Methods: The Cochrane Controlled Register of Trials, PubMed and Embase were used to perform a systematic review using the following search terms: (meniscus OR meniscal) AND (root OR posterior horn) AND (suture OR tape OR wire OR cord). Data pertaining to certain biomechanical properties (load to failure, stiffness, displacement during cyclical loading and at failure), meniscal healing and patient-reported outcome measures (PROMs) were extracted.

New approaches to the single-interval adjustment matrix yes-no task.

Two adaptations of the Single-Interval Adjust-Matrix Yes-No (SIAM-YN) task, designed to increase the efficiency of absolute threshold estimation, are described. The first, the SIAM Twin Track (SIAM-TT) task, consists of two interleaved tracks of the standard SIAM-YN that are run in the same trial with a single response. The second new task modifies the binary SIAM-YN task by using a six-point rating-scale (SIAM-Rating).

Model based optimization for refractive index mismatched light sheet imaging.

Selective plane illumination microscopy (SPIM) is an optical sectioning imaging approach based on orthogonal light pathways for excitation and detection. The excitation pathway has an inverse relation between the optical sectioning strength and the effective field of view (FOV). Multiple approaches exist to extend the effective FOV, and here we focus on remote focusing to axially scan the light sheet, synchronized with a CMOS camera's rolling shutter.
