Influence of seasonal and spatial variations in physico-chemical parameters and plankton and macrophyte abundance on the diet composition of Labeo gonius in Chashma Lake, Indus River.

The feeding ecology of freshwater fish is strongly influenced by environmental variability, yet few studies have assessed how both seasonal and spatial changes in water quality and plankton dynamics affect the diet of native species in South Asian river-lake systems. This study explores seasonal and spatial variations in the diet composition of Labeo gonius in relation to physico-chemical parameters and plankton abundance in Chashma Lake, Pakistan. Monthly sampling from 2022 to 2023 was conducted at three ecologically distinct sites to assess water quality, phytoplankton, macrophytes, zooplankton, and fish gut content.

Ethnomedicinal documentation of plants used for gastrointestinal disorders in Sahiwal District Pakistan.

The gastrointestinal tract is regarded as vulnerable due to frequent exposure to a variety of foods. Diarrhea, ulcers, constipation, and parasitic infections are considered to be the most prevalent disorders worldwide. The present study was conducted in the District Sahiwal to appraise the local flora for the treatment of a diverse range of gastrointestinal disorders (GIDs) for the first time.

Human health risk of heavy metal biomagnification: Trophic transfer patterns in aquatic ecosystems.

Background: Heavy metal contamination in aquatic ecosystems poses significant ecological and human health risks, particularly through trophic transfer in food webs.

Objective: This study investigates the mean concentrations and trophic transfer of heavy metals (Cd, Cu, Cr, and Pb) across various environmental compartments (water, sediment, plankton) and trophic levels (three fish species: Catla. catla, Labeo rohita, and Cyprinus carpio) in an aquatic ecosystem.

Sludge removal frequency influences heavy metal accumulation, water quality, and growth in Nile tilapia (Oreochromis niloticus) biofloc systems.

Heavy metals (HMs) are one of the emerging micropollutants, which have been found a significant toxicant to the fish fauna; therefore, the current study aimed to examine HMs including Cd, Cr, Pb, and Cu concentrations in sludge and their accumulation in Oreochromis niloticus tissues along with growth and water quality in Biofloc Technology (BFT). Tilapia, initially weighing 0.40 ± 0.

Impact of heavy metals on health and quality of cultured in biofloc and earthen pond systems.

Heavy metal contamination in aquaculture threatens fish health and consumer safety, with bioaccumulation differing between farming systems. The study compares heavy metal (Cd, Cr, Pb and Cu) contamination in fish feed, water and organs (muscle, gills and liver) of Nile tilapia () from biofloc and pond farming systems. Samples were collected from ten biofloc tanks and ten earthen ponds, with heavy metals quantified using atomic absorption spectrophotometry.

Rational designing of ZIF-67-derived CoO nanocomposite with hierarchical porous structure and extensive peroxidase mimetic activities for highly sensitive colorimetric detection of nitrite in drinking water.

A simple, fast, and cost-effective colorimetric nitrite (NO) sensor based on ZIF-67-derived CoO nanocomposite (ZCo-2 NC) structure has been developed. The prepared colorimetric sensor (ZCo-2 NC) was employed to sensitively detect NO in drinking water system by the exhibition of promising peroxidase-mimicking nanozyme-like features. The sensor manifest well-determined sensing response with excellent linear and wide range of NO sensitivity (0.

Turmeric counteracts manganese-associated deteriorations in liver and kidney tissues: histomorphometric and biochemical insights.

Nowadays, Manganese (Mn) become an unavoidable ingredient in agriculture, medical and manufacturing industries. Manganese deficiency is rare, and even though recurrent exposure to manganese is inevitable for humans, concerns have been voiced regarding public health hazards. This research was designed to evaluate the manganese toxicity and potential protective effects of turmeric in Swiss albino male mice.

Protective potential of fresh orange juice against zinc oxide nanoparticles-induced trans-placental and trans-generational toxicity in mice.

Due to the emerging applications of nanoparticles, human exposure to nanoparticles is unavoidable, particularly to zinc oxide nanoparticles (ZnO NPs), owing to their wide range of usage. The ongoing study aimed to evaluate trans-generational toxic potential of ZnO NPs through exposure to F0 mothers, in F1 pups and F1 mature offspring and the protective potential of fresh orange juice (OJ). Twenty-eight F0 mothers were randomly allocated into four groups ( = 7), control; untreated, dose group; exposed to ZnO NPs, dose+antidote group; coadministered ZnO NPs + OJ, antidote group; OJ, during the organogenetic period.

Sodium arsenate induced genotoxicity, morphometric and morphological changes in mice embryo and protective role of Moringa oleifera extracts.

The present study was carried out to find the comparative ameliorative role of Moringa oleifera leaf and flower extracts against sodium arsenate induced genotoxic, morphometric and morphological changes in mice embryo. Seven to eight week old pregnant females (N=44) with body weight of 20-25g at gestation day zero were divided randomly in groups (A, B, C, D, E, F, G, H, I, J and K). Group A was of control while all others were experimental groups and administered with selected doses of sodium arsenate as toxicant (6mg/kg B.
