Disperse Red 1 azo dye: Consequences of low-dose/low-concentration exposures in mice and zebrafish.

Color Index Disperse Red 1 (DR1), an azo dye widely used in the textile industry and released into aquatic environments, is genotoxic in somatic cells, but little is known concerning its effects on the reproductive system or the early stages of embryonic development. We have assessed the effects on the spermatozoa of male mice following oral exposure to the dye, at low doses, for 14 days. Measured endpoints were DNA damage (comet assay), miRNA-34c levels, and sperm number, morphology, and motility.

Deficit Irrigation with Silicon Application as Strategy to Increase Yield, Photosynthesis and Water Productivity in Lettuce Crops.

In regions where water is a limited resource, lettuce production can be challenging. To address this, water management strategies like deficit irrigation are used to improve water-use efficiency in agriculture. Associating this strategy with silicon (Si) application could help maintain adequate levels of agricultural production even with limited water availability.

Assessing the phytotoxicity of wastewater from the structured-bed hybrid baffled reactor (SBHBR) for agricultural reuse during the germination phase.

This study investigated the quality of anaerobic (AnE) and oxic/anoxic (O/A) effluents from a continuous-feed structured-bed hybrid baffled reactor (SBHBR) treating dairy wastewater impacts on lettuce and cucumber germination. While sustainable technologies like SBHBR have successfully removed organic matter and total nitrogen from dairy wastewater, residual concentrations may still represent a risk to water resources. Therefore, phytotoxicity bioassays were conducted with lettuce and cucumber seeds in contact with effluent during early stages to evaluate the potential implications of dairy wastewater reuse in agriculture.

Microneedling on the external female genitalia's flaccidity in patients with Ehlers-Danlos: Case report.

Introduction: The Ehlers-Danlos Syndrome (EDS) can presentis a reduction in fibroblast proliferation and collagen production. Microneedling a minimally invasive technique that through mechanical stimulus there is incentive to the production of collagen and elastin.

Objective: Present a case study in a patient with EDS complaining of flaccidity on large genital labia, using microneedling as a therapeutic proposal.

Potential benefits of near critical and supercritical pre-treatment of lignocellulosic biomass towards anaerobic digestion.

Vegetable crop residues, such as sugarcane bagasse (SCB), despite their limited biodegradability, are potential materials for anaerobic processes because of their low cost, high availability, and sugar content. The difficulty of biodegrading this type of material is primarily related to its chemical composition and to the complex interactions between its compounds (cellulose, hemicelluloses, and lignin). Thus, the following supercritical and near critical carbon dioxide (CO) pre-treatments were evaluated with and without the addition of sodium hydroxide (NaOH): (i) 40°C/70 kgf·cm; (ii) 60°C/200 kgf·cm; and (iii) 80°C/200 kgf·cm, aiming to enhance the anaerobic biodegradability of SCB.

Ketogenic Diet Based on Extra Virgin Coconut Oil Has No Effects in Young Wistar Rats With Pilocarpine-Induced Epilepsy.

This study evaluated the effects of a ketogenic diet (KD) based on extra virgin coconut oil (Cocos nucifera L., VCO), on the treatment of epileptic rats. Two sets of experiments were conducted.

Parasitological risk assessment from wastewater reuse for disposal in soil in developing countries.

The purpose of this work is to analyze the parasitological risks of treated wastewater reuse from a stabilization pond in the city of Piracicaba, in the State of São Paulo (Brazil), and the level of treatment required to protect public health. Samples were taken from raw and treated wastewater in stabilization ponds and submitted to a parasitological, microbiological and physicochemical analysis. The study revealed on treated wastewater the presence of Ascaris sp.
