The findings highlight the moderating effects of Age, Gender, and Country.2,2'-Dihydroxybenzophenone-S-methyl-thiosemicarbazone and 3-methoxy-salicylaldehyde were reacted in the presence of oxovanadium(IV) or nickel(II) ions to yield the N2O2-type-chelate complex. The synthesized complexes were characterized by employing elemental analysis, electronic and infrared spectra, 1H NMR spectra, magnetic measurements, and thermogravimetric analyses. The expected structures of oxovanadium(IV) and nickel(II) complexes were confirmed by using the single-crystal X-ray diffraction method. The presence of π-π stacked dimeric structures provided stronger crystalline formations. The optimized geometries and vibrational frequencies of the compounds were obtained using the DFT/ωB97XD method with the 6-31G (d,p) basis set and compared with the experimental data. The electrochemical characterization of the oxovanadium(IV) and nickel(II) complexes were carried out by using the cyclic voltammetry (CV) method. The oxovanadium(IV) complex gives a ligand-centered oxidation and a metal-centered one electron reduction and oxidation peaks corresponding to the VIV/IIIO and VIV/VO, respectively. The nickel(II) complex gives a ligand-centered oxidation and metal-centered (NiII/I) reduction peaks in a dimethyl sulfoxide (DMSO) solution. The redox potentials were calculated in terms of Gibbs free energy change of the redox reaction at the theory level of M06-L/LANL2DZ/PCM. In addition, the energy gap, HOMO and LUMO distributions were calculated.  https://www.selleckchem.com/products/afuresertib-gsk2110183.html  The total antioxidant capacities of the compounds were determined by using cupric reducing antioxidant capacity (CUPRAC) method, in which the oxovanadium(IV) complex was found to be powerful as an antioxidant agent.
  The COVID-19 pandemic has had a significant impact worldwide, at different levels. The literature consulted indicates that healthcare workers, who are the first to respond, are generally the ones who pay the highest price. The present study assesses the extent of anxious and depressive symptoms among these actors responding to COVID-19, in the context of Cameroon.
 
  The Hospital Anxiety and Depression Scale (HADS) was used to assess anxious and depressive symptoms. Data collection involved the use of a web questionnaire for this purpose through the Google Forms virtual platform. The questionnaire link was sent to professional groups spread throughout Cameroon's ten regions. A total of 331 health professionals were interviewed over the period from April 5 to 19, 2020.
 
  The results show a high rate of anxiety (41.8%) and depression (42.8%). There is a higher susceptibility to depression in young people (30-39 years). Fear of contamination and fear of death are modulators of depression and anxiety. The anxietare staff involved in the response to COVID-19 in Cameroon are significantly affected in their mental health. This underlines the need for specialized psychological help for nursing staff.During the COVID-19 pandemic, different nations have adopted a variety of response strategies to fight and contain the new coronavirus. Such national response strategies can be classified into three categories based on their underlying philosophy strict control with unlimited resources, relentless contribution with limited resources, and rough rationality with limited resources. We discuss the philosophies, characteristics, and performances of the three response strategies and when they should be adopted. We also examine what marketing innovation strategies enterprises should adopt to survive and grow their businesses in both the short and long term. This study provides important strategic implications for national policymakers and enterprises on the use of response strategies as well as marketing innovation tactics and strategies to be used both during and after the pandemic.In this paper, we provide a retrospective cohort study with patients that have been hospitalized for general or intensive care unit admission due to COVID-19, between March 3 and July 29, 2020, in the state of Bahia, Brazil. We aim to correlate those patients' demographics, symptoms and comorbidities, with the risk of mortality from COVID-19, length of hospital stay, and time from diagnosis to definitive outcome. On the basis of a dataset provided by the Health Secretary of the State of Bahia, we selected 3,896 hospitalized patients from a total of 154,868 COVID-19 patients that included non-hospitalized patients and patients with invalid registration in the dataset. Then, we statistically analyzed whether there was a significant correlation between the patient record data and the COVID-19 pandemic, and our main findings reinforced by the use of a multivariable logistic regression were that older age (Odds Ratio [OR] = 1.03, 95% Confidence Interval [CI] = 1.03-1.04, p-value (p) less then 0.001), an initial symptom of shortness of breath (OR = 1.88, 95% CI = 1.60-2.20, p less then 0.001), and the presence of comorbidities, mainly chronic kidney disease (OR = 2.41, 95% CI = 1.67-3.48, p less then 0.001) are related to an increased risk of mortality from COVID-19. On the other hand, sore throat (OR = 0.74, 95% CI = 0.58-0.95, p = 0.02) and length of hospital stay (OR = 0.96, 95% CI = 0.58-0.95, p less then 0.001) are more related to a reduced risk of mortality from COVID-19. Moreover, a multivariable linear regression conducted with statistically significant variables (p less then 0.05) showed that age (OR = 0.97, 95% CI = 0.95-0.98, p less then 0.001) and time from diagnosis to definitive outcome (OR = 1.67, 95% CI = 1.64-1.71, p less then 0.001) are associated with the length of hospital stay.Recent research suggests that democratic presidential elections held using a runoff rule produce presidents that are more likely to protect human rights, in comparison to those elected under plurality rule; with this follow-up article, I seek to highlight the importance of advancing to a runoff round for those elections held using a runoff rule. I find that for presidential democracies that already have a runoff rule in place, country-years where the president has been elected after a runoff round are more likely to be associated with high government respect for human rights, in comparison to country-years where the president has been elected after only one round (that could have advanced to a runoff round, but did not). This article provides decision-makers with more information regarding the human rights consequences of runoff rounds, so that the costs and benefits of adopting (or retaining) variations of a runoff rule can be better weighed.
