Discovery of clustered regularly interspaced short palindromic repeats (CRISPR)/Cas system has greatly improved the gene editing technology. Their applications in the area of diagnostic innovation are gaining much attention. The key characteristics of CRISPR/Cas system that allowed its extensive exploitation in the detection platform are their programmable and highly selective target recognition scheme. Herein, this review presents the major three Cas effectors (Cas9, Cas12, and Cas13) and their significance in various detection assays. The CRISPR/Cas detection strategies, based on their target hybridization, cleavage activity, sensor capabilities, and signal readout methods, are discussed. Some of the recent progressions, challenges, and improvement strategies of CRISPR/Cas technology are highlighted and their biosensing detection platforms toward the development of simple, sensitive, and portable point-of-care diagnostic devices are presented.

We generated soybean mutants related to two ß-amyrin synthase genes using DNA-free site-directed mutagenesis system. Our results suggested that one of the genes is predominant in the soyasaponin biosynthesis. Soyasaponins, which are triterpenoid saponins contained in soybean [Glycine max (L.

Background: High-grade serous ovarian cancer (HGSOC) accounts for 70-80% of all ovarian cancer-related deaths. Multiple studies have suggested that the fallopian tube epithelium (FTE) serves as the cell of origin of HGSOC. Phosphatase and tensin homolog () is a tumor suppressor and its loss is sufficient to induce numerous tumorigenic changes in FTE, including increased migration, formation of multicellular tumor spheroids (MTSs), and ovarian colonization.

Background: Leishmaniasis is a health problem in many regions with poor health and poor life resources. According to the World Health Organization (WHO), an estimated 700,000-1 million new cases arise annually. Effective control of sand fly vector populations is crucial for reducing the transmission of this disease.

Background: People from lower socioeconomic groups are more likely to smoke and less likely to succeed in achieving abstinence, making tobacco smoking a leading driver of health inequalities. Contextual factors affecting subpopulations may moderate the efficacy of individual-level smoking cessation interventions. It is not known whether any intervention performs differently across socioeconomically-diverse populations and contexts.

The presence of the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas system in the superbug presents a unique opportunity to precisely target and edit bacterial genomes to modify their drug resistance. The objective was to detect the prevalence of CRISPR in extensively and pan-drug-resistant and to determine the utility of whole-genome sequencing (WGS) for the analysis of the entire genome for such strains. The antimicrobial susceptibilities of one hundred isolates were assessed using the antibiotic susceptibility test (AST) card of the VITEK system.
