The results of phytochemical screening revealed the presence of tannins, flavonoids, reducing sugars, cardiac glycosides, saponins, and steroids from the prepared crude extracts. The ethanolic and hexanolic extracts had activity on multidrug-resistant Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, and methicillin-susceptible Staphylococcus aureus with the mean and standard error zone of inhibition that ranged from 8.5 ± 0.5 to 16.5 ± 0.25 mm; however, the extracts were found not to have activity on resistant E. coli and Salmonella typhimurium. The ethanolic crude extract had the lowest MIC and MBC values of 31.25 and 125 mg/ml, respectively, compared to the hexane extract which had the MIC and MBC values of 62.50 and 250 mg/ml, respectively. This provides the evidence for its usage as an alternative herbal remedy for the treatment of diarrhoea caused by susceptible and methicillin-resistant Staphylococcus aureus and multidrug resistant Pseudomonas aeruginosa.<br /><br /> Meaning in life is one of the psychological domains that is most severely affected in patients with life-threatening illnesses. The importance of meaning-making mandates the development of reliable tools to assess this construct. Steger's Meaning in Life Questionnaire (MLQ) is one of the most valid and reliable instruments that determines the search for and presence of meaning in life. The present study was conducted to provide psychometric data on the MLQ in a sample of patients with life-threatening illnesses.<br /><br /> The MLQ was completed by 301 patients (aged 20-80 years) diagnosed with life-threatening illnesses (cancer and multiple sclerosis) and referred to hospitals. Confirmatory factor analysis and Pearson's correlation test were used to determine the construct validity of the questionnaire.<br /><br /> The confirmatory factor analysis supported the original two-factor model of the MLQ, comprised of the presence of meaning (five items) and search for meaning (five items). The responses to the MLQ did not differ by sociodemographic factors. Most importantly, contrary to previous findings, the correlation between the two subscales, i.e., search for meaning and presence of meaning, was significant and positive.<br /><br /> The results showed that the MLQ is a valid and reliable measure for assessing meaning in life that can be applied in research on meaning in life among other patient populations.<br /><br />The results showed that the MLQ is a valid and reliable measure for assessing meaning in life that can be applied in research on meaning in life among other patient populations.<br /><br /> Radiotherapy is one of the main treatments for pancreatic cancer, but radiation resistance limits its clinical application. As a result, novel therapeutic agents to improve radiosensitivity are urgently needed. This study aimed to investigate the effect of Ibr-7 (a derivative of ibrutinib) on the radiosensitivity of human pancreatic cancer cells.<br /><br /> The effect of Ibr-7 on pancreatic cancer cell proliferation was detected by CCK-8 assays. Radiosensitivity was assessed by clonogenic formation assays. Cell cycle and cell apoptosis were analysed by flow cytometry. DNA damage was evaluated by immunofluorescence analysis. [https://www.selleckchem.com/products/piperacillin.html read more] The expression levels of PARP, Cleaved caspase 3, p-EGFR and EGFR were determined by western blot.<br /><br /> Ibr-7 showed an anti-proliferative effect on PANC-1 and Capan2 cells in a dose- and time-dependent manner. Ibr-7 (2μmol/L) enhanced the effect of radiation on PANC-1 and Capan2 cells. Further findings showed that this combination enhanced G2/M phase arrest and increased cell apoptosis. Additional molecular mechanism studies revealed that the expression of p-EGFR was decreased by Ibr-7 alone or in combination with radiation. Overexpression of p-EGFR reversed the cell apoptosis induced by Ibr-7 combined with radiation. Moreover, the expression of γ-H2AX was significantly decreased in the Ibr-7 plus radiation group.<br /><br /> Our study indicated the potential application of Ibr-7 as a highly effective radiosensitizer for the treatment of pancreatic cancer cells.<br /><br />Our study indicated the potential application of Ibr-7 as a highly effective radiosensitizer for the treatment of pancreatic cancer cells.<br /><br /> A lower recruitment and high turnover rate of registered nurses have resulted in a global shortage of nurses. In the UK, prior to the COVID-19 epidemic, nurses' intention to leave rates were between 30 and 50% suggesting a high level of job dissatisfaction.<br /><br /> In this study, we analysed data from a cross-sectional mixed-methods survey developed by the Royal College of Nursing and administered to the nursing workforce across all four UK nations, to explore the levels of dissatisfaction and demoralisation- one of the predictors of nurses' intention to leave. We carried out logistic regression analysis on available data in order to determine what impacts job dissatisfaction.<br /><br /> In total, 1742 nurses responded to questions about working conditions on their last shift. We found that nearly two-thirds of respondents were <br /><br /> . Nurses were five times more likely (OR 5.08, 95% CI 3.82-6.60) to feel demoralised if they reported <br /><br /> A perceived <br /><br /> had nearly the same impact on the level of demoralisation (OR 4.8, 95% CI 3ir ability to provide safe, good-quality care. These findings predate the current Covid-19 pandemic outbreak which may have had a further detrimental effect on job satisfaction in the UK and other nation's nursing workforce.<br /><br /> Interleukin-17 plays important roles in allergic diseases. Several studies proved that leptin promoted Th17 immune responses by inducing ROR<br /><br /> t transcription. ILC2 is an important member of the early stage of immune response. Therefore, we aimed to explore the effect of leptin on the IL-17 production by ILC2 in AR in this study.<br /><br /> Fifteen AR patients and fifteen healthy controls were enrolled. Serum leptin levels were measured, and their correlation with the frequency of IL-17+ ILC2 cells was analyzed using enzyme-linked immunosorbent assay (ELISA) and flow cytometry. ILC2 was stimulated by leptin, and the expression of IL-17, IL-5, and IL-13 was detected by ELISA. The correlated pathways were confirmed by real-time PCR.<br /><br /> We found that serum leptin and the frequency of IL-17-producing ILC2s in AR were significantly higher compared with those in controls. After being incubated with leptin, the frequency of IL-17+ ILC2 cells and IL-17 production from ILC2 was upregulated compared with that in controls. We also found that leptin induced ROR<br /><br /> t and Ahr expression by ILC2.
