Understanding why some people establish and maintain effective control of HIV-1 and others do not is a priority in the effort to develop new treatments for HIV/AIDS. Using a whole-genome association strategy, we identified polymorphisms that explain nearly 15% of the variation among individuals in viral load during the asymptomatic set-point period of infection. One of these is found within an endogenous retroviral element and is associated with major histocompatibility allele human leukocyte antigen (HLA)-B*5701, whereas a second is located near the HLA-C gene. An additional analysis of the time to HIV disease progression implicated two genes, one of which encodes an RNA polymerase I subunit. These findings emphasize the importance of studying human genetic variation as a guide to combating infectious agents.

Ongoing efforts to improve sheep reference genome assemblies still leave many gaps and incomplete regions, resulting in a few common failures and errors in genomic studies. Here, we report a 2.85-Gb gap-free telomere-to-telomere genome of a ram (T2T-sheep1.

Low-coverage whole-genome sequencing (LcWGS), a cost-effective genotyping method, offers greater flexibility in variant detection than does single-nucleotide polymorphism (SNP) chips. However, to our knowledge, no studies have explored the application of LcWGS in sheep. This study aimed to evaluate the feasibility of implementing LcWGS and genotype imputation and assess their applicability in genomic studies of body weight and milk yield in sheep.

Canine pyometra is a common and potentially life-threatening reproductive disorder in intact female dogs. This prospective study aimed to (1) investigate the bacterial spectrum and antimicrobial susceptibilities of bacterial isolates from the uterus and urine of dogs with pyometra, (2) assess the clonal relatedness and virulence factors of Escherichia coli isolates from individual dogs, and (3) determine the occurrence of concurrent and persistent bacteriuria or clinical urinary tract infections. Bacterial isolates from 208 uterine and 203 urine specimens collected during pyometra surgery were analyzed.

Background: Hidradenitis Suppurativa (HS) is a chronic inflammatory skin condition with a greater prevalence and disease burden in patients who identify as African American and those with a family history of HS, suggesting a strong genetic component to its pathogenesis.
Objective: To evaluate the relationship between plasma inflammatory protein expression, HS disease severity, and genetic ancestry in a diverse cohort of patients with Hidradenitis Suppurativa.
Methods: We performed a case-control study of patients with HS compared to age-, sex-, and ethnicity-matched healthy controls.

Objective: In this study, we examined the genetic, medical, and molecular traits of two Han Chinese families with the tRNA G5783A mutation to investigate the relationship between mitochondrial DNA (mtDNA) mutations and major depressive disorder (MDD).
Methods: Clinical data and comprehensive mitochondrial genomes were collected from the two families. Variants were assessed for evolutionary conservation, allelic frequencies, and their structural and functional impacts.
