The Camelidae family, ranging from southwest Asia to north Africa, South America, and Australia, includes key domesticated species adapted to diverse environments. Among these, the Arabian camel () is vital to the cultural and economic landscape of the Arabian Peninsula. This review explores the mitochondrial DNA of the dromedary camel, focusing on the D-loop region to understand its genetic diversity, maternal inheritance, and evolutionary history.

High-throughput DNA and RNA sequencing are revolutionizing precision oncology, enabling personalized therapies such as cancer vaccines designed to target tumor-specific neoepitopes generated by somatic mutations expressed in cancer cells. Identification of these neoepitopes from next-generation sequencing data of clinical samples remains challenging and requires the use of complex bioinformatics pipelines. In this paper, we present GeNeo, a bioinformatics toolbox for genomics-guided neoepitope prediction.

The red palm weevil (RPW), (Coleoptera: Curculionidae), is the most devastating pest of palm trees worldwide. Mitigation of the economic and biodiversity impact it causes is an international priority that could be greatly aided by a better understanding of its biology and genetics. Despite its relevance, the biology of the RPW remains poorly understood, and research on management strategies often focuses on outdated empirical methods that produce sub-optimal results.

Steindachner, 1866, a genus of Mormyridae (Teleostei: Osteoglossomorpha), has been monotypic since the description of (Steindacher, 1866) from a single specimen. No type locality other than "Angola" was given and almost no specimens have been subsequently identified to this species. In order to investigate the relationship of this taxon to fresh specimens collected in Angola and elsewhere, whole genome paired-end sequencing of DNA extracted from the holotype specimen of was performed and a nearly complete mitogenome assembled from the sequences obtained.

Weevils, classified in the family Curculionidae (true weevils), constitute a group of phytophagous insects of which many species are considered significant pests of crops. Within this family, the red palm weevil (RPW), , has an integral role in destroying crops and has invaded all countries of the Middle East and many in North Africa, Southern Europe, Southeast Asia, Oceania, and the Caribbean Islands. Simple sequence repeats (SSRs), also termed microsatellites, have become the DNA marker technology most applied to study population structure, evolution, and genetic diversity.

: Transposable elements (TEs) are the largest component of the genetic material of most eukaryotes and can play roles in shaping genome architecture and regulating phenotypic variation; thus, understanding genome evolution is only possible if we comprehend the contributions of TEs. However, the quantitative and qualitative contributions of TEs can vary, even between closely related lineages. For palm species, in particular, the dynamics of the process through which TEs have differently shaped their genomes remains poorly understood because of a lack of comparative studies.

Background: Transposable elements (TEs) are common features in eukaryotic genomes that are known to affect genome evolution critically and to play roles in gene regulation. Vertebrate genomes are dominated by TEs, which can reach copy numbers in the hundreds of thousands. To date, details regarding the presence and characteristics of TEs in camelid genomes have not been made available.

Middle East respiratory syndrome is a severe respiratory illness caused by an infectious coronavirus. This virus is associated with a high mortality rate, but there is as of yet no effective vaccine or antibody available for human immunity/treatment. Drug design relies on understanding the 3D structures of viral proteins; however, arriving at such understanding is difficult for intrinsically disordered proteins, whose disorder-dependent functions are key to the virus's biology.

Lactic acid bacteria are known to exhibit probiotic properties through various mechanisms, including competitive exclusion, pathogen inhibition, production of antimicrobial substances, and maintenance of eubiosis. Here, we present the draft genome sequence of a novel probiotic strain, strain NRRL B-442, which exhibits potent antivirulence activity against .

Nonsteroidal anti-inflammatory drugs are the most commonly used medications for pain control in dentistry. The reported adverse effects include gastrointestinal and cardiovascular events, alterations in renal function, and effects on blood pressure, hepatic injury, and platelet inhibition which can lead to increased bleeding. This case report describes an unusual rare adverse event of the use of ibuprofen for pain control post restorative treatment.

Background: The aim of this study was to evaluate cyclooxygenase-2 (COX-2) immunoreactivity in colorectal adenocarcinomas and to find correlations with different pathological features.

Materials And Methods: This study included 35 cases of colorectal carcinoma for which surgical colectomy specimens were collected. Immunohistochemical staining of COX-2 (cyclooxygenase-2) is done by using the Streptavidin-biotin technique.

Article Synopsis
  • - The study focuses on sequencing the complete DNA of the dromedary camel (Camelus dromedarius), resulting in the creation of camel EST libraries with 70,272 reads and yielding 23,602 putative gene sequences, including over 4,500 potentially novel genes.
  • - Functional annotation and analysis comparison to other species like humans and mice showed successful characterization, with over 80% of identified gene fragments having significant open reading frames (ORF) greater than 300 bp.
  • - The research introduces an online resource called CAGBASE, which hosts a database of annotated EST sequences and provides tools for further genomic studies and whole genome sequencing of camels.
