Single nucleotide polymorphisms are the most common form of DNA alterations at the level of a single nucleotide in the genomic sequence. Genome-wide association studies (GWAS) were carried to identify potential risk genes or genomic regions by screening for SNPs associated with disease. Recent studies have shown that SCN9A comprises the NaV1.7 subu...

Nanoparticles have a wide range of physiochemical properties that can harm many organs, tissues, enzymatic and hormonal activities. Throughout the world, silver nanoparticles (AgNPs) are frequently used in consumer products. The aim of the current study was to synthesize the AgNPs and to investigate their impact on hormones, antioxidant enzymatic a...

The study of nanoparticles has grown in significance during the last several years. Nanoparticles are a kind of material that is composed of very tiny particles. Nanoparticle characteristics vary greatly depending on their size and form. The surface of a nanoparticle significantly affects its optical, mechanical, magnetic, and other characteristics...

Helicobacter pylori is a stomach bug that causes very serious stomach problems. This gram-negative bacterium has thirty-five different species in the Helicobacter genus, and some of these can be found in the gut lining. People with low economic status have a significant rate of infection. This chapter discusses the history, virulence factors, and m...

Fasciolosis is a severe trematode parasitic infection in sheep and goats caused by fasciola hepatica. It is classified as a chronic tropical disease and is prevalent in more than 50 nations, specifically where sheep and cattle are reared. This illness is more widespread in northern Pakistan, incurring major financial losses due to a decrease in she...

Baya weaver is found in floodplains of Pakistan and is famous for building retort shaped hanging nests. For this study, 24 samples of baya weaver (twelve from both sexes) were collected from the wild habitat to analyze morphometry, haematology, and gut contents. Morphometric parameters e.g., body weight was measured with the help of a weight balanc...

Food consumption is increasing due to rapid population growth. Fish is one of the most important animal foods, providing a high amount of energy in the form of proteins, essential amino acids, nutrients, vitamins, and minerals. Antibiotics are used to control several pathogens that harm fish. However, the use of antibiotics in fish causes numerous...
