Combined with a system for identifying each of the chromosomes in a genome, visualizing the location of individual genetic loci by fluorescence in situ hybridization (FISH) would aid in assembling physical and genetic maps. Previously, large genomic clones have been successfully used as FISH probes onto somatic chromosomes but this approach is complicated in species with abundant repetitive elements. In this study, repeat-free portions of sequences that were anchored to particular chromosomes including genes, gene clusters, large cDNAs, and portions of BACs obtained from public databases were used to label the corresponding physical location using FISH. A collection of probes that includes at least one marker on each chromosome in the maize complement was assembled, allowing a small-target karyotyping system to be developed. This set provides the foundation onto which additional loci could be added to strengthen further the ability to perform chromosomal identification in maize and its relatives. The probes were demonstrated to produce signals in several wild relatives of maize, including Zea luxurians, Z. diploperennis, and Tripsacum dactyloides.

Salmonella Typhimurium (S. Typhimurium) is one of the most common food-borne diseases, highlighted as the top food-borne bacterial pathogen in the world with a low infectious dose (1 CFU) and high mortality rate. It is commonly associated with numerous foods such as dairy products, protein sources (multiple types of meat, poultry, and eggs), and bakery products.

Nitrifying communities in activated sludge play a crucial role in biological nitrogen removal processes in municipal wastewater treatment plants. While extensive research has been conducted in temperate regions, limited information is available on nitrifiers in tropical regions. The present study investigated all currently known nitrifying communities in two full-scale municipal wastewater treatment plants in Malaysia operated under low-dissolved oxygen (DO) (0.

Background: Dermal clear cell sarcoma (DCCS) is a rare malignant mesenchymal neoplasm. Owing to the overlaps in its morphological and immunophenotypic profiles with a broad spectrum of tumors exhibiting melanocytic differentiation, it is frequently misdiagnosed as other tumor entities in clinical practice. By systematically analyzing the clinicopathological characteristics, immunophenotypic features, and molecular biological properties of DCCS, this study intends to further enhance pathologists' understanding of this disease and provide a valuable reference for its accurate diagnosis.

Background: Blinatumomab and inotuzumab ozogamicin (InO) are B-cell targeted agents used in the frontline and relapsed/refractory treatment of B-cell acute lymphoblastic leukaemia (B-ALL). Blinatumomab, a bispecific T-cell engager that targets CD19 and CD3, and InO, an antibody-drug conjugate targeting CD22, have both shown efficacy. However, recent reports have noted lineage conversion as a complication when these agents are used individually or sequentially.

Objective: Differentiating between the repertoire of immunoglobulin rearrangements is important in guiding diagnoses and management of B-cell lymphoma processes. A subset of these disease entities, such as chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL), can show distinct genomic profiles with a shared cell of origin. In this report, we describe a rare case in which differentiating between the immunoglobulin family of rearrangements (IGH, IGK, IGL) with optical genome mapping (OGM) helped revise the clinical suspicion of CLL.
