Pharmacological treatment for methamphetamine withdrawal: A systematic review and meta-analysis of randomised controlled trials.

Issues: Cessation of methamphetamine use may result in a characteristic withdrawal syndrome, no medication has been approved for this indication. This systematic review aims to assess the efficacy of pharmacotherapy for methamphetamine withdrawal, the first comprehensive meta-analysis since 2008.

Approach: MEDLINE (1966-2020), CINAHL (1982-2020), PsychINFO (1806-2020) and EMBASE (1947-2020) were systematically searched.

DIALS as a toolkit.

The DIALS software for the processing of X-ray diffraction data is presented, with an emphasis on how the suite may be used as a toolkit for data processing. The description starts with an overview of the history and intent of the toolkit, usage as an automated system, command-line use, and ultimately how new tools can be written using the API to perform bespoke analysis. Consideration is also made to the application of DIALS to techniques outside of macromolecular X-ray crystallography.

How to probe the spin contribution to momentum relaxation in topological insulators.

Topological insulators exhibit a metallic surface state in which the directions of the carriers' momentum and spin are locked together. This characteristic property, which lies at the heart of proposed applications of topological insulators, protects carriers in the surface state from back-scattering unless the scattering centres are time-reversal symmetry breaking (i.e.

The Effects of Caffeine Supplementation on Physiological Responses to Submaximal Exercise in Endurance-Trained Men.

Objectives: The aim of this study was to evaluate the effects of caffeine on physiological responses to submaximal exercise, with a focus on blood lactate concentration ([BLa]).

Methods: Using a randomised, single-blind, crossover design; 16 endurance-trained, male cyclists (age: 38 ± 8 years; height: 1.80 ± 0.
