Unlabelled: Genotypic methods for detecting antibiotic resistance in infection offer a rapid, convenient, and accurate approach for tailored therapy. However, existing studies predominantly examine single sample types and lack comparative analyses across different samples. This study comprehensively detects and compares genotypic resistance to clarithromycin and levofloxacin in gastric mucosa, gastric fluid, and fecal samples from the same patients.

Article Synopsis
  • The study analyzed how doping bismuth silicate (BSO) with europium (Eu) affects its crystal structure and charge distribution using density functional theory (DFT) and Materials Studio software.
  • It investigated different ratios of Eu doping (1/12, 1/6, and 1/3) using a virtual crystal approximation, revealing that higher doping levels disrupt crystal symmetry.
  • The findings indicated that as the doping ratio increases to 1/3, both the Eu-O and Bi-O bond lengths exhibit significant changes, suggesting enhanced covalence between these atoms at this optimal doping level.

The fortification of bread is considered an effective approach for improving its nutritional properties. However, the incorporation of free bioactive components into bread formulations may affect the overall quality of breads in different ways, depending on the sensitivity of bioactive components to baking factors. In this study, the incorporation of encapsulated vitamin C (ascorbic acid and its salts) and fish oil in breads was investigated for their stability and effect on bread quality.

The cyclohexane organic acid 3-dehydroshikimate (DHS) has potent antioxidant activity and is widely utilised in chemical and pharmaceutical industries. However, its production requires a long fermentation with a suboptimal yield and low productivity, and a disproportionate growth-to-production ratio impedes the upscaling of DHS synthesis in microbial cell factories. To overcome these limitations, competing and degradation pathways were knocked-out and key enzymes were balanced in an engineered Escherichia coli production strain, resulting in 12.

The localization of the meiotic specific regulatory molecule Moa1 to the centromere is regulated by the kinetochore protein CENP-C, and participates in the cohesion of sister chromatids in the centromere region mediated by the cohesin Rec8. To examine the interaction of these proteins, we analyzed the interactions between Moa1 and Rec8, CENP-C by yeast two-hybrid assays and identified several amino acid residues in Moa1 required for the interaction with CENP-C and Rec8. The results revealed that the interaction between Moa1 and CENP-C is crucial for the Moa1 to participate in the regulation of monopolar attachment of sister kinetochores.

During meiosis, defects in cohesin localization within the centromere region can result in various diseases. Accurate cohesin localization depends on the Mis4-Ssl3 loading complex. Although it is known that cohesin completes the loading process with the help of the loading complex, the mechanisms underlying its localization in the centromere region remain unclear.

Background: Neutrophils play important roles in atherosclerosis and atherothrombosis. Bactericidal/permeability-increasing protein (BPI) is mainly expressed in the granules of human neutrophils in response to inflammatory stress. This observational, cross-sectional study investigated the plasma level of BPI in patients with acute coronary syndrome (ACS) and its correlation with blood neutrophil counts and circulating inflammatory biomarkers.

Ssu72 is a component of the yeast cleavage/polyadenylation factor (CPF) complex, which catalyzes the dephosphorylation of the C-terminal domain (CTD) of RNA polymerase II at S5-P and S7-P. It has been shown that Ssu72 phosphatase is involved in regulating chromosome cohesion during mitosis. To further clarify whether Ssu72 phosphatase affects chromosome separation during meiotic division in , we utilized green fluorescent protein (GFP) to label centromeres and red fluorescent protein to label microtubule protein Atb2.
