Parasitological diagnosis in ornamental freshwater fish from different fish farmers of five Brazilian states
This study aimed to search parasites in 333 ornamental fish from five Brazilian states (Ceará, Minas Gerais, São Paulo, Paraná and Santa Catarina). Fish were sent from eight farms located in the municipalities of Fortaleza, Patrocínio do Muriaé, São Francisco do Glória, Cascavel, Timbó, Iguape, Jacareí and Mairinque. All fish received anesthesia earlier to euthanasia procedures. After the search for parasites, it was verified that 70.6% (235/333) of fishes were infected by at least one type of parasite, being 12 types of parasites identified: monogeneans, digenean metacercariae, cestodes, nematodes, Lernaea cyprin...

Comparison of Essential and Toxic Metals Levels in some Herbal Teas: a Systematic Review
Biol Trace Elem Res. 2023 May 17. doi: 10.1007/s12011-023-03698-w. Online ahead of print.ABSTRACTIn the present study, we reviewed the literature as a systematic review to investigate the concentration of some metals (essential, none essential, and toxic metals) in herbal teas and their health risks. The search extended the literature from the database, including Google Scholar, PubMed, and Scopus, using the terms "herbal teas" combined with "heavy metals, essential metals, thyme, rosemary, chamomile, and tea" also with "iron, zinc, aluminum, chromium, cobalt, nickel, manganese, arsenic, cadmium, and lead" in titles and ab...

Mechanisms of group-hunting in vertebrates
Biol Rev Camb Philos Soc. 2023 May 18. doi: 10.1111/brv.12973. Online ahead of print.ABSTRACTGroup-hunting is ubiquitous across animal taxa and has received considerable attention in the context of its functions. By contrast much less is known about the mechanisms by which grouping predators hunt their prey. This is primarily due to a lack of experimental manipulation alongside logistical difficulties quantifying the behaviour of multiple predators at high spatiotemporal resolution as they search, select, and capture wild prey. However, the use of new remote-sensing technologies and a broadening of the focal taxa beyond ap...

SGR: an online genomic resource for the woodland strawberry
Conclusions: The SGR database is developed to facilitate dissemination and data mining of extensive floral and fruit transcriptome data in the woodland strawberry. It enables users to mine the data in different ways to study different pathways or biological processes during reproductive development.

Reactive Searching and Infotaxis in Odor Source Localization
by Nicole Voges, Antoine Chaffiol, Philippe Lucas, Dominique Martinez Male moths aiming to locate pheromone-releasing females rely on stimulus-adapted search maneuvers complicated by a discontinuous distribution of pheromone patches. They alternate sequences of upwind surge when perceiving the pheromone and cross- or downwind casting when the odor is lost. We compare four search strategies: three reactive versus one cognitive. The former consist of pre-programmed movement sequences triggered by pheromone detections while the latter uses Bayesian inference to build spatial probability maps. Based on the analysis of triphas...

Do greater mouse-eared bats experience a trade-off between energy conservation and learning? RESEARCH ARTICLES
Ireneusz Ruczyłski, Theresa M. A. Clarin, and Bjoern M. Siemers Bats, some species of rodents and some birds are able to save energy during the summer period by decreasing their body temperature and falling into torpor. Some studies indicate that torpor prevents sleeping and causes effects similar to sleep deprivation. Impairment of processes stabilizing memory slows down learning accuracy and speed. We conducted two experiments to test whether greater mouse-eared bats, Myotis myotis, which commonly use torpor during the summer period, experience a trade-off between energy savings and learning abilities. We compared...

MetaboNexus: an interactive platform for integrated metabolomics analysis
Abstract MetaboNexus is an interactive metabolomics data analysis platform that integrates pre-processing of raw peak data with in-depth statistical analysis and metabolite identity search. It is designed to work as a desktop application hence uploading large files to web servers is not required. This could speed up the data analysis process because server queries or queues are avoided, while ensuring security of confidential clinical data on a local computer. With MetaboNexus, users can progressively start from data pre-processing, multi- and univariate analysis to metabolite identity search of significant mole...

Towards Improving Searches for Optimal Phylogenies
We present an approach for finding exact optimal solutions that employs and complements the current heuristic methods for finding optimal trees. Given a set of taxa and a set of aligned sequences of characters, there may be subsets of characters that are compatible, and for each such subset there is an associated (possibly partially resolved) phylogeny with edges corresponding to each character state change. These perfect phylogenies serve as anchor trees for our constrained search space. We show that, for sequences with compatible sites, the parsimony score of any tree $$T$$ is at least the parsimony score of the anchor t...

Enrichment Assessment of Multiple Virtual Screening Strategies for Toll‐Like Receptor 8 Agonists Based on a Maximal Unbiased Benchmarking Data Set
This article is protected by copyright. All rights reserved. A comprehensive assessment of multiple virtual screening strategies for Toll‐like Receptor 8 agonists including knowledge‐based pharmacophore (KBP), shape‐based 3D similarity search (ROCS) and combined strategies against a maximum‐unbiased benchmarking data set specialized for TLR8 agonists. The enrichment assessment demonstrated a considerable performance through our selected three‐layer virtual screening strategy: knowledge‐based pharmacophore (Phar1) screening, followed by shape‐based 3D similarity search (Q4_combo), and then a Gold docking scre...

Lévy Walks Suboptimal under Predation Risk
by Masato S. Abe, Masakazu Shimada A key challenge in movement ecology is to understand how animals move in nature. Previous studies have predicted that animals should perform a special class of random walks, called Lévy walk, to obtain more targets. However, some empirical studies did not support this hypothesis, and the relationship between search strategy and ecological factors is still unclear. We focused on ecological factors, such as predation risk, and analyzed whether Lévy walk may not be favored. It was remarkable that the ecological factors often altered an optimal search strategy from Lévy walk to Brownian w...
