Article Abstract

We developed a time-saving and cost-efficient Pulsed Field Gel Electrophoresis (PFGE) method for the typing of Stenotrophomonas maltophilia by modifying the conventional procedures. Our modifications related to the cell suspension preparation, lysis of bacterial cells in plugs, washing steps, and consumption of restriction enzyme. Although few rapid PFGE protocols on Gram-negative bacteria are available, the use of comparatively large amounts of costly reagents prompted us to look for other alternative. Hence, by considering the speed, simplicity, and relatively low cost, the modified protocol may be of more practical value than other established protocols in investigating S. maltophilia nosocomial outbreaks.

Background: Breast-conserving surgery (BCS) is the primary surgical approach for patients with breast cancer. The accurate determination of surgical margins during BCS is critical for patient prognosis; however, time constraints and limitations in current pathological techniques often prevent pathologists from performing this assessment intraoperatively. The inability to reliably assess margins during surgery can lead to incomplete tumor removal and the need for additional surgeries.

Cathepsin K and glycosaminoglycans differentially regulate matrix metalloproteinase activity in dentin under various pH conditions.

This study examined the pH-dependent (3, 5, and 7) regulation of matrix metalloproteinase (MMP) activity by cathepsin K (catK) and glycosaminoglycans (GAGs) using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), fluorescence assays, and human dentin slice experiments. The direct effects of catK were evaluated in the catK-active, catK-deficient, and odanacatib (ODN)-inhibited groups, whereas indirect GAG/ tissue inhibitor of metalloproteinase (TIMP)-mediated regulation was assessed in the catK-active, ODN-inhibited, and chondroitin sulfate (CS)-treated groups through dimethylmethylene blue (DMMB) assays, in situ zymography, and immunofluorescence staining. CatK directly activated MMP-2 (62 kDa) and MMP-9 (82 kDa) at all pH values, with no activation observed in the ODN-inhibited or catK-deficient groups.

CircTTC3 regulates the osteogenic differentiation of adipose-derived mesenchymal stem cells via miR-205/Smad3 axis.

Adipose-derived mesenchymal stem cells (ADSCs) hold great promise for bone tissue repair and regeneration. Circular RNAs (circRNAs) play a crucial role in regulating the osteogenic differentiation and bone remodeling of ADSCs; however, the underlying molecular mechanisms remain unclear. In this study, we conducted whole transcriptome sequencing (WTS) on ADSCs and constructed a competing endogenous RNA (ceRNA) regulatory network to identify the circTTC3/miR-205/mothers against decapentaplegic homolog 3 (Smad3) signaling axis.

Antibiotic resistance is the never-ending war among medical researchers and microbial life forms. The extensive evolving potential of the microorganisms, in combination with improper usage, storage and disposal of the marketed antibiotics generated from natural or artificial sources, always calls for the need for novel antimicrobial agents with different modes of action. In this project, azo-oxime complexes of iron and manganese (seven in total) have been applied to wild multidrug-resistant pathogenic bacterial strains (isolated from sewage water of hospital).
