Acute toxicity and biodistribution assessment of quantum dots conjugated to lectins from leaves (SteLL) and sarcotesta (PgTeL).

This work reports the investigation of telluride cadmium quantum dots (CdTe QDs) conjugated to plant lectins from (SteLL) and (PgTeL) for acute toxicity and genotoxicity in healthy mice and 24-h biodistribution in sarcoma 180-bearing animals. Acute toxicity data indicated their safety, despite some histopathological alterations. Comet assay revealed that the QDs-PgTeL group presented a higher damage index and frequency of damage than the negative control.

Evaluation of traditional and bootstrapped methods for assessing data-poor fisheries: a case study on tropical seabob shrimp () with an improved length-based mortality estimation method.

Background: Unrealistic model assumptions or improper quantitative methods reduce the reliability of data-limited fisheries assessments. Here, we evaluate how traditional length-based methods perform in estimating growth and mortality parameters in comparison with unconstrained bootstrapped methods, based on a virtual population and a case study of seabob shrimp ( Heller, 1862).

Methods: Size data were obtained for 5,725 seabob shrimp caught in four distinct fishing grounds in the Southwestern Atlantic.

Carbohydrate-Binding Mechanism of the Coagulant Lectin from Seeds (cMoL) Is Related to the Dimeric Protein Structure.

This study characterized the binding mechanisms of the lectin cMoL (from Moringa oleifera seeds) to carbohydrates using spectroscopy and molecular dynamics (MD). The interaction with carbohydrates was studied by evaluating lectin fluorescence emission after titration with glucose or galactose (2.0-11 mM).

Why Has a Progressive Court Failed to Protect the Prison Population against COVID-19? Mass Incarceration and Brazil's Supreme Court.

Despite acknowledging the risks of the COVID-19 pandemic for the prison population, Brazil's Supreme Court declined to issue structural injunctions during the health crisis ordering lower courts to consider these risks when making incarceration-related decisions. These injunctions could have been crucial to mitigate mass incarceration and protect the prison population during the pandemic. Through an examination of the Supreme Court's rulings in structural cases and in a sample of over 4,000 habeas corpus decisions, this paper argues that granting these injunctions would have overwhelmed the court with an unmanageable influx of individual claims.

Evaluation of acute toxicity, 28-day repeated dose toxicity, and genotoxicity of Moringa oleifera leaves infusion and powder.

Ethnopharmacological Relevance: Moringa oleifera Lam. leaves infusion and powder are widely used by population due the nutritional and medicinal potentials, however data regarding safety of use are still inconclusive, leading to prohibition of this plant in some countries.

Aim Of The Study: The present work investigated the nutritional and phytochemical composition, acute and 28-day repeated dose toxicity, and genotoxicity of M.

First record of parasitism by (Isopoda, Bopyridae) on the freshwater prawn (Decapoda, Palaemonidae) and ecological interactions.

In this study, we aimed to record, for the first time, parasitic infestation by the isopod on the prawn , as well as to register some ecological interactions. We hypothesized that the parasitic infection is able to negatively affect the prawn's nutritional condition and that this interaction can modify growth relationships in male individuals. We collected both parasitized (n = 25) and parasite-free (n = 25) individuals in several locations of the Contas River, state of Bahia, Brazil, which had their morphometric characteristics determined, including of the parasites.

Plastic ingestion lead to reduced body condition and modified diet patterns in the rocky shore crab Pachygrapsus transversus (Gibbes, 1850) (Brachyura: Grapsidae).

In this study, we aimed to identify impacts of plastic ingestion by the ecologically important rocky shore crab Pachygrapsus transversus. We sampled individuals from August 2019 to January 2020 in a reef environment and determined their body condition and diet diversity. In order to test our hypothesis that plastic retention in the foregut is able to decrease the condition factor, we compared it between contaminated and non-contaminated individuals.
