Long-term exposure of pancreatic islets to fatty acids (FAs), common in obesity, metabolic syndrome, and type 2 diabetes, leads a compensatory hyperactivity followed by inflammation, apoptosis, dysfunctional beta cells, results insulin dependence the patient. Restriction uptake islet cells may protect them from lipotoxicity.
The Egyptian fruit bat (Rousettus aegyptiacus) is a keystone species in the ecosystems, providing essential services like pollination and seed dispersal. However, its role as reservoir for zoonotic diseases poses significant health risk. present study aimed to investigate current future spatial distribution patterns of evaluate impact environmental factors such bioclimatic variables, ecoregion, land cover on their habitat suitability. Using records collected from published papers, data field...
Abstract Accounting for historical demographic features is vital many types of evolutionary inferences, including the estimation divergence times between closely related populations. In barn swallow, Hirundo rustica , inferring population sizes and subspecies can shed light on recent co‐evolution this species with humans. Pairwise sequentially Markovian coalescent uncovered growth beginning order one million years ago—which may reflect radiation broader genus—and a more decline....
Egypt is the habitat for a large number of bird species and serves as vital stopover millions migratory birds during their annual migration between Palearctic Afrotropical ecozones. Surveillance avian influenza viruses (AIVs) critical to assessing risks potential spreading these among domestic poultry. AIV hunted captured wild in was conducted order understand characteristics circulating viruses.Sampling occurred two locations along Mediterranean Coast period from 2014 2016. A total 1316...
Contamination from increased anthropogenic activities poses a threat to human health as well the ecosystem. To develop nanotechnological approach improve aqua fisheries, we synthesized magnetic hematite nanoparticle-based gel and evaluated its efficacy in cadmium-polluted closed system decontaminate water tilapia fish health.
Sex chromosomes often bear distinct patterns of genetic variation due to unique inheritance and demography. The processes mutation, recombination, drift selection also influence rates evolution on sex differently than autosomes. Measuring such differences provides information about how these shape genomic their roles in the origin species. To test hypotheses predictions autosomal sex-linked diversity differentiation, we measured population statistics within between populations subspecies...
Two aquatic macrophytes, Ceratophyllum demersum and Lemna minor, were used in aquaculture wastewater treatment. Tilapia fish (Oreochromis niloticus) with total body weight of 50-60 g placed 60 L aquaria. Four treatment groups included: control (no plant treatment, depended on artificial filtering for purification), minor (Lm), (Cd), mixed plants group (Lm+Cd). Each had three replicates (5 fish/replicate). The experiment was conducted 4 weeks. Physicochemical parameters including pH,...
The present study seeks to assess the bird biodiversity at Important Bird Area (IBA) and Ramsar site,Lake Burullus, northern Egypt. Waterbirds was assessed 14 selected sites in lake duringwinter spring seasons. assessment included richness, composition, evenness, abundance, andSimpson Shannon-Wiener diversity indices. species varied spatially temporallyamong different during period. Estimated richness 49 species. Winter birdswere mainly migratory waterbirds like waterfowl, distributed islets...
Bats are a good animal model of monitoring habitat pollution by heavy metal concentration assessment. A total 50 Egyptian fruit bat were sampled from five governorates: Beni Suef, Damietta, Fayoum, Giza and Menofia. Fur samples collected these bats to be tested for the presence metals using Atomic Absorption Spectrophotometry. Seven (manganese (Mn), zinc (Zn), cadmium (Cd), chromium (Cr), Ferrum (Fe), nickel (Ni), lead (Pb)) have been estimated. Statistical analysis with One-Way Analysis...
Studying migratory birds wintering stopover areas has a global concern. The contamination of heavy metals is one the serious threats to in wetland ecosystem. In present study, metal exposure risk Burullus Lake was assessed. concentrations Cr, Ni, Pb, Cd, and Co water, plant, fish were determined 10 bird habitats. A metals' assessment model had been done. It showed that small waders, represented by dunlin, are exposed higher doses than waterfowls, mallard. Evaluation this could not be done...
Quail hunting is a major socioeconomic practice in Egyptian coastal areas.The accumulation of cadmium feathers (chest and tail), muscle, kidneys livers were analyzed compared both wild migratory domesticated Japanese quails using atomic absorption spectrophotometry.Domesticated quail recorded higher concentrations than the one.Cadmium concentration was that pectoral muscle feathers.To assess potential risk to human health, daily intake (EDI) target hazard quotient (THQ) calculated.The EDI...

The present study was conducted to investigate the role of using plant-based wastes as a supplementary diet in improving hemato-biochemical blood status Oreochromis niloticus and resistance against mercuric chloride toxicity (0.08 mg/l).Fish were distributed (10 fish/40-liter aquarium) into 8 groups.Control group MC 0.08 fed on commercial diet; MC/OFI 5% & 10% supplemented with Opuntia ficus-indica; MC/MO Moringa Oleifera; MC/TO Telfairia occidentalis.The experiment extended for 60 days...
Egypt is home to diverse lakes that serve as appropriate habitats for a vast waterbird population, providing temporary shelter during winter migration and permanent dwellings.Among these lakes, Lake Qaroun in significant an important bird area, Ramsar site, protected area.The study aims state the status of most abundant species lake.Ten points were chosen represent lake coded from S1 S10.Furthermore, our investigation revealed among avian particularly waterfowl, slender-billed gull (Larus...
St. Catherine is a unique and remarkable stopover place for migratory birds high-quality resource habitat resident birds.St. an important bird area (IBA) declared protectorate.In the present study, community was surveyed across gradient of different types protectorate.A total 3884 individuals belonging to 73 species (represented by 12 orders 28 families) were recorded during period from June 2017 August 2018.The richness 25 with 3100 in abundance 7 16 families.The most abundant Chukar...
Anthropogenic contamination is spreading through every environment on the planet that affects whole biota.Negative effects have been observed recently in a number of taxa, including birds.Birds are crucial as bioindicators one best studied groups organisms because they noticeable, relatively simple to observe, and subject public interest concern.Therefore, evaluation lead (Pb) levels liver, muscle, kidney, feathers laughing dove (Streptopelia senegalensis), Egyptian barn swallow (Hirundo...
