Article Abstract
Drug resistance surveillance is a major integral part of malaria control programs. Molecular methods play a pivotal role in drug resistance detection and related molecular research. This study aimed to develop a rapid and accurate detection method for drug resistance of Plasmodium falciparum (P. falciparum). A quantitative real-time PCR (qPCR) assay has been developed that identifies the mutation at locus A256T in the P.falciparum multi-drug resistance(pfmdr1) gene producing amino acid change at position 86. The results of 198 samples detected by qPCR were consistent with nested PCR and sequencing, giving an accuracy of 94.3%. The sensitivity, specificity, positive and negative predictive value of qPCR were 85.7%, 97.6%, 90.0% and 96.4%, respectively. The results of qPCR are basically consistent with the nested PCR, which is expected to replace the nested PCR as a new molecular biological method for drug resistance detection, providing reliable technical support for global malaria prevention and control.

Resistance-conferring mutations in the androgen receptor (AR) ligand-binding pocket (LBP) compromise the effectiveness of clinically approved orthosteric AR antagonists. Targeting the dimerization interface pocket (DIP) of AR presents a promising therapeutic approach. In this study, we report the design and optimization of -(thiazol-2-yl) furanamide derivatives as novel AR DIP antagonists, among which was the most promising candidate.

Antimicrobial resistance (AMR) is a significant public health concern globally, and Pakistan is no exception. The misuse and overuse of antibiotics, inadequate regulation of their sale, and a lack of awareness contribute to the rising levels of AMR in the country. study presents a detailed analysis of blood and urine samples collected in Pakistan over various periods, focusing on pathogen prevalence, gender distribution, and age-wise patterns.

Crosstalk between leukemic cells and their surrounding mesenchymal stromal cells (MSCs) in the bone marrow microenvironment is crucial for the pathogenesis of myelodysplastic syndromes (MDS) and is mediated by extracellular vesicles (EVs). The EV-specific miRNAs derived from MDS-MSCs remain poorly explored. EVs isolated from HS-5, an immortalized stromal cell line, promoted the proliferation and 5-azacytidine (AZA) resistance of SKM-1 cells.

Antimicrobial resistance is largely driven by overuse of antibiotics, which is particularly common in low- and middle-income countries. We combine provider knowledge assessments and over 2000 anonymous standardized patient visits to providers in India to examine why they overprescribe antibiotics for pediatric diarrhea and figure out how to reduce overprescribing. Seventy percent of providers prescribed antibiotics without indication of bacterial infection.

IFN-β, a type I interferon, has been used as a first-line therapy for patients with multiple sclerosis (MS) for more than 30 years; however, the cellular and molecular basis of its therapeutic efficacy remains unclear. Here, we first used experimental autoimmune encephalomyelitis (EAE), a mouse model for MS, to show that the therapeutic effects of IFN-β were associated with a down-regulation of microRNA-21 (miR-21) and pathogenic T17 (pT17) cells. In vitro experiments demonstrated that genetic knockout of miR-21 directly inhibited pathogenic T17 cell differentiation.
