COVID-19 Lockdown: A Global Study Investigating the Effect of Athletes' Sport Classification and Sex on Training Practices.

Purpose: To investigate differences in athletes' knowledge, beliefs, and training practices during COVID-19 lockdowns with reference to sport classification and sex. This work extends an initial descriptive evaluation focusing on athlete classification.

Methods: Athletes (12,526; 66% male; 142 countries) completed an online survey (May-July 2020) assessing knowledge, beliefs, and practices toward training.

Training During the COVID-19 Lockdown: Knowledge, Beliefs, and Practices of 12,526 Athletes from 142 Countries and Six Continents.

Objective: Our objective was to explore the training-related knowledge, beliefs, and practices of athletes and the influence of lockdowns in response to the coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Methods: Athletes (n = 12,526, comprising 13% world class, 21% international, 36% national, 24% state, and 6% recreational) completed an online survey that was available from 17 May to 5 July 2020 and explored their training behaviors (training knowledge, beliefs/attitudes, and practices), including specific questions on their training intensity, frequency, and session duration before and during lockdown (March-June 2020).

Results: Overall, 85% of athletes wanted to "maintain training," and 79% disagreed with the statement that it is "okay to not train during lockdown," with a greater prevalence for both in higher-level athletes.

Description of a multifaceted intervention programme for fatigue after acquired brain injury: a pilot study.

The purpose of this pilot study was to describe and explore a group-based multifaceted intervention for patients with fatigue after acquired brain injury (ABI). We hypothesised that post-intervention changes would result in reduced fatigue, in addition to improved emotional health, sleep and attentional control. Eight subjects with traumatic brain injury (n = 3) and cerebrovascular insults (n = 5) were included.

Interactions stabilizing the C-terminal helix of human phospholipid scramblase 1 in lipid bilayers: A computational study.

The human phospholipid scramblase 1 (SCR) distributes lipids non-selectively between the cellular membrane leaflets. SCR has long been thought to be mostly localized in the cytoplasm (amino acids 1-287) and anchored to the membrane via the insertion of a 19 amino acid long transmembrane C-terminal helix (CTH, 288-306), which further extends to the exoplasmic side with a 12 amino acid long tail (307-318). Little is known about the structure of this protein, but recent experimental data on two CTH peptides (288-306 and 288-318) show that they insert through phospholipid bilayers and that the presence of cholesterol improves their affinity for lipid vesicles.
