The effects of runs-of-homozygosity on pig domestication and breeding.

Background: Since their domestication, recent inbreeding together with intensive artificial selection and population bottlenecks have allowed the prevalence of deleterious mutations and the increase of runs-of-homozygosity (ROH) in domestic pigs. This makes pigs a good model to understand the genetic underpinnings of inbreeding depression.

Results: Here we integrated a comprehensive dataset comprising 7239 domesticated pigs and wild boars genotyped by single nucleotide polymorphism (SNP) chips, along with phenotypic data encompassing growth, reproduction and disease-associated traits.

Increased oscillation rate may improve morcellation efficiency in HoLEP.

Introduction: Tissue morcellation has become increasingly efficient, yet remains a rate limiting step in holmium enucleation of the prostate (HoLEP). Limited data exists on how the rate of oscillation by the morcellator blades affects morcellation efficiency (ME).

Methods: We undertook a retrospective review of HoLEP procedures performed by two surgeons from July 1, 2019 to August 25, 2022.

Emerging hazardous chemicals and biological pollutants in Canadian aquatic systems and remediation approaches: A comprehensive status report.

Emerging contaminants can be natural or synthetic materials, as well as materials of a chemical, or biological origin; these materials are typically not controlled or monitored in the environment. Canada is home to nearly 7 % of the world's renewable water supply and a wide range of different kinds of water systems, including the Great Lake, rivers, canals, gulfs, and estuaries. Although the majority of these pollutants are present in trace amounts (μg/L - ng/L concentrations), several studies have reported their detrimental impact on both human health and the biota.

Efficient decaffeination with recyclable magnetic microporous carbon from renewable sources: Kinetics and isotherm analysis.

Rapid global urbanization and population growth have ignited an alarming surge in emerging contaminants in water bodies, posing health risks, even at trace concentrations. To address this challenge, novel water treatment and reuse technologies are required as current treatment systems are associated with high costs and energy requirements. These drawbacks provide additional incentives for the application of cost-effective and sustainable biomass-derived activated carbon, which possesses high surface area and low toxicity.

Single nucleotide polymorphisms (SNPs) in the open reading frame (ORF) of prion protein gene (PRNP) in Nigerian livestock species.

Background: Prion diseases, also known as transmissible spongiform encephalopathies (TSEs) remain one of the deleterious disorders, which have affected several animal species. Polymorphism of the prion protein (PRNP) gene majorly determines the susceptibility of animals to TSEs. However, only limited studies have examined the variation in PRNP gene in different Nigerian livestock species.

Characterization and population genetics of Haemonchus contortus in Merino sheep in Lesotho.

Haemonchus contortus is the most pathogenic and economically restrictive gastrointestinal nematode in the small ruminant industry globally. Morbidity, poor cross-bodily state, and mortality of sheep in Lesotho suggest the presence of H. contortus.

Advances in the design and use of carbon dots for analytical and biomedical applications.

Carbon dots (CDs) have garnered significant interest for their potential use in multiple applications due to their size, fluorescent properties, high photostability, low toxicity and biocompatibility. CDs can be tailored for specific needs, as they can be synthesized with diverse precursors and techniques for functionalization. Since the applications of CDs are rapidly expanding, this review highlights recent developments in this burgeoning field.

Target capture sequencing for the first Nigerian genotype I ASFV genome.

African swine fever (ASF) is a contagious viral disease that affects domestic pigs and wild boars, causing significant economic losses globally. After the first Nigerian outbreak in 1997, there have been frequent reports of ASF in pig-producing regions in the country. To facilitate control, it is important to understand the genotype and phylogenetic relationship of ASF viruses (ASFVs).

Attitude of postpartum women towards multiple postnatal clinic schedule in south-west Nigeria.

Background: The postnatal period is a critical in the lives of mothers and babies due to the risk of maternal and perinatal morbidity and mortality. According to the Nigeria Demographic Health Survey 2018, only 38 % of women and 42;% of newborns received a postnatal check in the first 2 days after birth. The World Health Organisation (WHO) recommends that postpartum women should have contact with healthcare providers within 24 h, at day 3, days 10-14 and 6 weeks post-delivery.

The study of selection signature and its applications on identification of candidate genes using whole genome sequencing data in chicken-a review.

Chicken is a major source of protein for the increasing human population and is useful for research purposes. There are almost 1,600 distinct regional breeds of chicken across the globe, among which a large body of genetic and phenotypic variations has been accumulated due to extensive natural and artificial selection. Moreover, natural selection is a crucial force for animal domestication.

Population structure and evolutionary history of the greater cane rat () from the Guinean Forests of West Africa.

Grasscutter () is a large-body old world rodent found in sub-Saharan Africa. The body size and the unique taste of the meat of this major crop pest have made it a target of intense hunting and a potential consideration as a micro-livestock. However, there is insufficient knowledge on the genetic diversity of its populations across African Guinean forests.

Polymorphism of prion protein gene (PRNP) in Nigerian sheep.

Polymorphism of the prion protein gene () gene determines an animal's susceptibility to scrapie. Three polymorphisms at codons 136, 154, and 171 have been linked to classical scrapie susceptibility, although many variants of have been reported. However, no study has investigated scrapie susceptibility in Nigerian sheep from the drier agro-climate zones.

Long amplicon HiFi sequencing for mitochondrial DNA genomes.

Long-read sequencing technology is a powerful approach with application in various genetic and genomic research.
