Lead is one of the most hazardous environmental pollutants in industrialized countries; lead exposure is a risk factor for osteoarthritis (OA) in older women. Here, the performance of several machine-learning (ML) algorithms in terms of predicting the prevalence of OA associated with lead exposure was compared. A total of 2224 women aged 50 years and older who participated in the Korea National Health and Nutrition Examination Surveys from 2005 to 2017 were divided into a training dataset (70%) for generation of ML models, and a test dataset (30%). We built and tested five ML algorithms, including logistic regression (LR), a k-nearest neighbor model, a decision tree, a random forest, and a support vector machine. All afforded acceptable predictive accuracy; the LR model was the most accurate and yielded the greatest area under the receiver operating characteristic curve. We found that various ML models can be used to predict the risk of OA associated with lead exposure effectively, using data from population-based survey.Herein, we describe the synthesis, structural elucidation, and DNA interaction of newly synthesized Cu(II) and Zn(II) complexes, i.e., [Cu(SB)(L-trp)(H2O)2]NO3 (1) and [Zn(SB)(L-trp)(H2O)2]NO3 (2) (SB = Schiff base obtained from the reaction between o-vanillin and 2-amino-2-methylpropane-1,3-diol; L-trp = L-tryptophan). From the analysis, a six-coordinated environment around the Cu(II) or Zn(II) center is proposed. The ability of the complexes to bind with calf thymus DNA was examined by optical spectroscopy (UV-vis titrations and steady-state fluorescence emission) and viscosity measurements. The vivid experimental results revealed that complexes 1 and 2 avidly bind to DNA through surface and groove binding modes, albeit with dissimilar intrinsic binding constants (1.54 × 104 and 1.36 × 104 M-1 for 1 and 2, respectively). Both complexes can displace ethidium bromide (EB) to some extent from the intercalated EB-DNA system, resulting in fluorescence quenching. Additional experiments such as [Fe(CN)6]4--induced quenching and thermal melting confirmed the electrostatic and groove binding mode. Furthermore, molecular docking studies verified that both complexes locate in the DNA minor groove by surface binding and were stabilized through weak intermolecular forces. The binding affinity of the lowest energy docked pose was found to be -5.37 kcal/mol for complex 1 and - 5.18 kcal/mol for complex 2. The present work is expected to pave the way for the synthesis of DNA-targeting Cu(II)/Zn(II) metal complexes for the development of chemotherapeutic agents.A total of 24 strains of Vibrio alginolyticus were isolated from cockles (Anadara granosa) and identified for VibA and gyrB genes. All V. alginolyticus isolates were then tested against nine different antibiotics. In this study, the highest percentage of antibiotic resistance was obtained against penicillin (37.50%), followed by ampicillin, vancomycin (12.50%) and erythromycin (8.33%). All of V. alginolyticus isolates were susceptible against streptomycin, kanamycin, tetracycline, chloramphenicol and sulfamethoxazole. Polymerase chain reaction (PCR) assay has confirmed the presence of four antibiotic resistance genes of penicillin (pbp2a), ampicillin (blaOXA), erythromycin (ermB) and vancomycin (vanB). Out of 24 V. alginolyticus isolates, 2 isolates possessed the tdh-related hemolysin (trh) (strains VA15 and VA16) and none for the thermostable direct hemolysin (tdh) gene. Both strains of the tdh-related hemolysin (trh) were susceptible to all antibiotics tested. The multiple antibiotic resistance (MAR) index ranging between 0.2 and 0.3 with 5 antibiograms (A1-A5) was observed. Combination of enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR) and antibiotic resistance indicated 18 genome types which showed genetic heterogeneity of those V. alginolyticus isolates. The results demonstrated the presence of V. alginolyticus strain found in cockles can be a potential risk to consumers and can contribute to the deterioration of human health in the study area. Thus, it is essential for local authority to provide the preventive measures in ensuring the cockles are safe for consumption.
Positive work environment is the corner stone for control and relief of work to family conflict (WFC).

To determine the prevalence work-family spillovers and to study the relations between them and work environment characteristics among full-time female employees at Tanta University Medical Campus.

A cross-sectional study was carried among female employees working in the five faculties that are present at Tanta University Medical Campus. A total of 442 female workers were recruited. Data were collected using a self-administered questionnaire including personal characteristics, work-related data, and home responsibilities. Job characteristics scales, work to family, and family to work spillovers scales were used to study their correlation.

Participants' mean age was 39.87 ± 10.07 years. Approximately half of participants had moderate degrees of both positive and negative work to family and family to work spillovers. Significant positive correlation was detected between skills discretion and both of postively high. EN4 purchase Significant relations were detected between work-family spillovers and work environment characteristics regarding skills discretion, work demands, decision authority, coworkers, and supervisors' support.Differential biomarker responses may occur after acute or chronic bioassays when animals are unfed. In many aquatic species, food deprivation may lead to a pro-oxidant condition. However, information about its effects on the oligochaete Lumbriculus variegatus, a bioindicator organism for water and sediment toxicity tests, is almost completely lacking. Acute (48 h) and chronic (21 days) bioassays were performed using unfed L. variegatus to assess the impact of food deprivation on several biomarkers related to the redox cellular status. Results showed that food deprivation inhibited the antioxidant enzymes superoxide dismutase and catalase, whilst levels of total glutathione (t-GSH) and lipid peroxidation processes increased with respect to controls. The same biomarkers were evaluated in unfed organisms exposed to tributyltin (TBT), nano-goethite or a binary mixture of both, for 48 h and 21 days. After 48 h, the organisms were able to cope with chemical stressors by enhancing antioxidant defences and lipid peroxidation processes were not observed.
