The snow must go on: how German cross-country skiers maintained training and performance in the face of COVID-19 lockdowns.

Background: The Covid-19 pandemic in 2020 led to disruption of sporting events, with athletes obliged to comply with national lockdown restrictions.

Purpose: To investigate the effect of the Covid-19 pandemic restrictions on national-team XC skiers' annual and weekly training distribution from training diaries, results from submaximal and maximal physiological roller ski tests, and competition results from the International Ski and Snowboard Federation (FIS) world cup.

Methods: Annual and weekly training type (specific, non-specific, strength, other) and intensity distribution (TID) data were collected for 12 German XC-skiers (Tier 4/5; BM: 67 ± 7 kg; age 26 ± 3 years; 6♀: V̇O 61.

Chemical Stability of mRNA/cDNA Complexes: Defining the Limits of mRNA Display.

Messenger RNA (mRNA) display is being increasingly adopted for peptide drug candidate discovery. While many conditions have been reported for the affinity enrichment step and in some cases for peptide modification, there is still limited understanding about the versatility of peptide-puromycin-mRNA/cDNA (complementary DNA) complexes. This work explores the chemical stability of mRNA/cDNA hybrid complexes under a range of different fundamental chemical conditions as well as with peptide modification conditions reported in an mRNA display setting.

"I find it hard to change poor food habits": Measuring food choice motives in an emerging economy.

Food choices are driven by an array of motives that have been approached, determined and quantified in a number of ways, mainly in developed countries. The objective of this study was to better understand the motives behind food choices in an emerging economy by collecting information from urban people in South Africa in a series of four studies. (1) Items generated through focus group discussions with low, middle and high income participants by Magano et al.

Plant-based meat alternatives in South Africa: An analysis of products on supermarket shelves.

All over the world, the development of products that resemble meat but contain predominantly plant-sourced ingredients is a prime focus. Meat obtained by rearing animals is associated with a range of important issues related to the sustainability of the planet. Locally, the topic is trending and the cause of various debates among industry role players.

South African Consumers' Knowledge, Opinions and Awareness of Whole Grains and Their Health Benefits: A Cross-Sectional Online Survey.

Evidence indicates that whole-grain food consumption reduces the risk of cardiovascular disease, type-2 diabetes, and some cancers. Increasing whole-grain consumption in developing countries is likely to significantly benefit the health of the population. However, there is very limited information on consumer whole-grain knowledge, attitudes, and behaviors in developing countries.
