Predicting the occurrence of minor adverse events in cardiac rehabilitation using physical variables.

The safety of exercise practice by individuals with cardiovascular disease is due to a good clinical evaluation to identify patients with a higher risk of adverse events, thus the study of simple variables capable of predicting the rate of events during exercise is relevant and may provide better screening tools to be applied in the clinical practice. The study aimed to evaluate if clinical and physical parameters can predict the rate of adverse events during exercise-based cardiac rehabilitation. This was a cohort study that followed 73 patients during 24 sessions of exercise.

The Amphibian Genomics Consortium: advancing genomic and genetic resources for amphibian research and conservation.

Amphibians represent a diverse group of tetrapods, marked by deep divergence times between their three systematic orders and families. Studying amphibian biology through the genomics lens increases our understanding of the features of this animal class and that of other terrestrial vertebrates. The need for amphibian genomic resources is more urgent than ever due to the increasing threats to this group.

Multinational evaluation of genetic diversity indicators for the Kunming-Montreal Global Biodiversity Framework.

Under the recently adopted Kunming-Montreal Global Biodiversity Framework, 196 Parties committed to reporting the status of genetic diversity for all species. To facilitate reporting, three genetic diversity indicators were developed, two of which focus on processes contributing to genetic diversity conservation: maintaining genetically distinct populations and ensuring populations are large enough to maintain genetic diversity. The major advantage of these indicators is that they can be estimated with or without DNA-based data.

Understanding food waste-reducing platforms: A mini-review.

Food waste is one of the main obstacles to transitioning to sustainable and circular food systems. Food waste-reducing platforms (FWRPs) have emerged as low-cost alternatives by donating or commercializing surpluses and non-commercial food. However, as a recent phenomenon, little is known about their actual contribution to the fight against food waste.

Perceptions and preferences of patients with cardiac conditions to the inclusion of virtual reality-based therapy with conventional cardiovascular rehabilitation: A qualitative study.

Background: Virtual reality-based therapy (VRBT) has been recently used in rehabilitation programs, as it can improve patient's adherence to treatment. However, patients' acceptance of VRBT has been scarcely investigated.

Objective: To qualitatively analyze the perceptions and preferences of patients about the inclusion of VRBT to a conventional cardiovascular rehabilitation program (CRP).

Advertising patterns of a fast-food chain on social media in Brazil.

Objective: To investigate the advertising patterns on the posts of a fast-food chain in Brazil on three social media platforms in 2019.

Design: An exploratory cross-sectional study.

Setting: Advertising strategies on the posts of a major fast-food chain on their official Facebook, Instagram and YouTube accounts.

Horizon scanning for South African biodiversity: A need for social engagement as well as science.

A horizon scan was conducted to identify emerging and intensifying issues for biodiversity conservation in South Africa over the next 5-10 years. South African biodiversity experts submitted 63 issues of which ten were identified as priorities using the Delphi method. These priority issues were then plotted along axes of social agreement and scientific certainty, to ascertain whether issues might be "simple" (amenable to solutions from science alone), "complicated" (socially agreed upon but technically complicated), "complex" (scientifically challenging and significant levels of social disagreement) or "chaotic" (high social disagreement and highly scientifically challenging).

Sexual dimorphism in bite performance drives morphological variation in chameleons.

Phenotypic performance in different environments is central to understanding the evolutionary and ecological processes that drive adaptive divergence and, ultimately, speciation. Because habitat structure can affect an animal's foraging behaviour, anti-predator defences, and communication behaviour, it can influence both natural and sexual selection pressures. These selective pressures, in turn, act upon morphological traits to maximize an animal's performance.

A molecular phylogeny of the African plated lizards, genus Gerrhosaurus Wiegmann, 1828 (Squamata: Gerrhosauridae), with the description of two new genera.

We constructed a molecular phylogeny of the African plated lizard family Gerrhosauridae using two mitochondrial markers (ND2, 732 bp; 16S, 576 bp) and one nuclear marker (PRLR, 538 bp). This analysis showed that the subfamily Gerrhosaurinae consists of five major clades which we interpret as representing five genera. The genera Tetradactylus and Cordylosaurus were each recovered as monophyletic, but Gerrhosaurus as currently conceived is paraphyletic, consisting of three distinct genus-level assemblages.

Slow but tenacious: an analysis of running and gripping performance in chameleons.

Chameleons are highly specialized and mostly arboreal lizards characterized by a suite of derived characters. The grasping feet and tail are thought to be related to the arboreal lifestyle of chameleons, yet specializations for grasping are thought to exhibit a trade-off with running ability. Indeed, previous studies have demonstrated a trade-off between running and clinging performance, with faster species being poorer clingers.
