Gonadal expression profiles reveal the underlying mechanisms of temperature effects on sex determination in the large-scale loach (Paramisgurnus dabryanus).

The sex determination mechanism in large-scale loach (Paramisgurnus dabryanus) follows a ZZ/ZW system, with sexual differentiation regulated by both genotypic factors and temperature effects (GSD+TSD), where elevated temperatures result in a higher proportion of males. Currently, research on the sex determination mechanisms in large-scale loach is limited, and the specific gene expression profiles and the role of temperature in influencing sex remain largely unknown. This study investigated the impact of temperature on the sex ratio in cultured populations of the large-scale loach, and then identified a female-specific genetic marker by whole genome sequencing, facilitating the distinguishing of females, males, and pseudo-males within this population.

Physiological and histopathological effects of polystyrene nanoparticles on the filter-feeding fish Hypophthalmichthys molitrix.

Excessive use of plastics in daily life is causing plastic pollution in aquatic environment and threatening the aquatic life. Therefore, research on the plastic pollution in aquatic environment is crucial to understand its impact and develop effective solution for safeguarding aquatic life and ecosystem. The current study investigated the effects of water borne polystyrene nanoparticles (PS-NPs) on hemato-immunological indices, serum metabolic enzymes, gills, and liver antioxidant parameters, plasma cortisol level and histopathological changes in liver and gill tissues of the widely distributed fish Hypophthalmichthys molitrix.

Reduced toxic effects of nano‑copper sulfate in comparison of bulk CuSO on biochemical parameters in the Rohu (Labeo rohita).

Considering the wide application of nanoparticles in various fields of life and growing concern regarding their toxic effects, the present study was designed with the aim to evaluate the potential risks of using copper sulfate nanoparticles (CuSO-NPs) in comparison to bulk form. Nanoparticles of CuSO, having mean size of 73 nm were prepared by ball milling method, and fingerlings of Labeo rohita were exposed to two levels, 20 and 100 μg L of CuSO in both bulk and nano forms for 28 days and their comparative effects on the metallothioneins (MTs), heat shock proteins 70 (HSP 70), lipid profile, cholesterol (CHOL) and triglyceraldehyde (TG) levels, activities of some metabolic enzymes Alanine transaminase (ALT), Aspartate transaminase (AST) Akaline phosphatase (ALP), and genes expressions of HSP-70, TNF-α and IL1-ß were investigated. CuSO showed the concentration and particle type dependent effects.

Toxicity of synthesized silver nanoparticles in a widespread fish: A comparison between green and chemical.

Metallic nanoparticles are gaining importance in various fields of life due to their large surface area to volume ratio. However, metallic nanoparticles pose different toxic effects on fish when they appear with different shapes and compositions in water. Herein the present study was designed to evaluate the median (LC) and sub-lethal (1/10th of LC) concentrations of Ag-Green NPs, 700 μg/L for Ag-Chem NPs, and 50 μg/L for AgO-Chem NPs were confirmed in Hypophthalmichthys molitrix.

A facile and simple microwave-assisted synthesis method for mesoporous ultrathin iron sulfide nanosheets as an efficient bifunctional electrocatalyst for overall water splitting.

The engineering of inexpensive, high-efficiency and stable electrodes related to both the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is highly desired for full water splitting devices to promote future advances in this energy technology. Therefore, a large surface area, rich in exposed surface atoms, and mesoporosity are very effective parameters in electrochemical reactions. Herein, we have, for the first time, synthesized free-standing mesoporous FeS nanosheets with a large surface area of 129.

Nanosheets structures can be employed as the most promising electrode material to enhance electrochemical performance for supercapacitors. Nickel Selenide (NiSe) nanosheets are synthesized using a rapid microwave synthesis method in a single step. The NiSe nanosheets possess a high surface area (125 mg) with a hexagonal crystalline structure.

Dietary supplementations of methionine improve growth performances, innate immunity, digestive enzymes, and antioxidant activities of rohu (Labeo rohita).

The dietary composition of fish constitutes numerous immune and growth-promoting substance; during the current study, methionine was amended in the diet of Labeo rohita (L. rohita), in order to appraise the diverse modulatory effects of methionine supplementation. Fish were grouped into three on the basis of methionine as methionine supplemented group 1 (MSG1), methionine supplemented group 2 (MSG2), and CTRL (control group).

Cuprous Self-Doping Regulated Mesoporous CuS Nanotube Cathode Materials for Rechargeable Magnesium Batteries.

Copper sulfides are broadly explored as the possible cathode materials for rechargeable magnesium batteries on account of their high theoretical capacity of 560 mAh g. However, the CuS cathodes usually suffer from serious capacity decay caused by structure collapse during the repeated magnesiation/demagnesiation process. Herein, we present a cuprous self-doping strategy to synthesize mesoporous CuS nanotubes with robust structural stability for rechargeable magnesium batteries and regulate their electrochemical magnesium storage behavior.
