Article Abstract
Apicomplexan parasites are single-celled obligate intracellular eukaryotic organisms that cause significant animal and human disease and pose a substantial health and socioeconomic burden worldwide. Eimeria acervulina is one such parasite of chickens, representative of several Eimeria species causing coccidiosis disease. A complete assembly of the E. acervulina genome may help identify markers of drug-resistance and design recombinant vaccines. We sequenced E. acervulina APU1 strain using Oxford Nanopore Sequencing and Illumina technology in combination with a Hi-C (Omni-C) proximity linkage library and achieved a chromosomal scale assembly using the MaSuRCA assembler. The final assembly was 52 Mb. with 15 chromosomes and 99% BUSCO completeness. A total of 7,621 genes were predicted using a pipeline of BRAKER3, GeneMark-ETP and AUGUSTUS, of which 4,647 (60.97%) have a predicted Pfam function and 1,962 (25.74%) have Gene Ontology (GO) terms matching molecular, biological, and functional classes. Stage-specific transcriptome analysis revealed 9,761 transcripts. This genome assembly and transcriptome analysis provides the foundation for identifying biologically important candidates for anticoccidial drug and vaccine development.

Background And Objective: Parental chromosomal structural variations (SVs) represent a primary genetic factor contributing to recurrent spontaneous abortion (RSA). Individuals carrying SVs with complex chromosomal rearrangements (CCRs) typically exhibit a normal phenotype but are at an increased risk of miscarriage. Current standard clinical detection methods are insufficient for the identification and interpretation of all SV types, particularly complex and occult SVs, thereby presenting a significant challenge for clinical genetic counseling.

High-throughput chromosome conformation capture (Hi-C) provides genome-wide insights into chromatin interactions within the three-dimensional structure of the nucleus, making it a powerful tool for studying genome architecture. Here, we provide a modified in situ Hi-C protocol for small cell numbers, utilizing 50-100 embryonic cells at the 8-cell stage to investigate chromatin organization during bovine early embryonic development. This protocol overcomes the challenges of limited sample availability and offers valuable insights into chromatin dynamics during bovine early embryogenesis.

The origin and phylogenetic distribution of symbiotic associations between nodulating angiosperms and nitrogen-fixing bacteria have long intrigued biologists. Recent comparative evolutionary analyses have yielded alternative hypotheses: a multistep pathway of independent gains and losses of root nodule symbiosis vs. a single gain followed by numerous losses.

Background: Although previous studies suggested associations between psoriasis and atopic dermatitis (AD), the directionality and causality of these relationships remain controversial. This study employed bidirectional Mendelian randomization to investigate the potential causal relationships between these two inflammatory skin conditions.
Methods: Genome-wide association statistics were obtained for psoriasis and AD from large-scale consortia and meta-analyses of genome-wide association studies.

Background: Population pharmacokinetic models can potentially provide suggestions for an initial dose and the magnitude of dose adjustment during therapeutic drug monitoring procedures of imatinib. Several population pharmacokinetic models for imatinib have been developed over the last two decades. However, their predictive performance is still unknown when extrapolated to different populations, especially children.
