The present study evaluated the effects of heme oxygenase-1 (HO-1) induction on the changes in renal outer medullary nitric oxide (NO) and peroxynitrite levels during 45-min renal ischemia and 30-min reperfusion in anesthetized rats. Glomerular filtration rate (GFR), outer medullary blood flow (OMBF), HO and nitric oxide synthase (NOS) isoform expression, and renal low-molecular-weight thiols (–SH) were also determined. During ischemia significant increases in NO levels and peroxynitrite signal were observed (from 832.1 ± 129.3 to 2,928.6 ± 502.0 nM and from 3.8 ± 0.7 to 9.0 ± 1.6 nA before and during ischemia, respectively) that dropped to preischemic levels during reperfusion. OMBF and –SH significantly decreased after 30 min of reperfusion. Twenty-four hours later, an acute renal failure was observed (GFR 923.0 ± 66.0 and 253.6 ± 55.3 μl·min−1·g kidney wt−1 in sham-operated and ischemic kidneys, respectively; P < 0.05). The induction of HO-1 (CoCl2 60 mg/kg sc, 24 h before ischemia) decreased basal NO concentration (99.7 ± 41.0 nM), although endothelial and neuronal NOS expression were slightly increased. CoCl2 administration also blunted the ischemic increase in NO and peroxynitrite (maximum values of 1,315.6 ± 445.6 nM and 6.3 ± 0.5 nA, respectively; P < 0.05), preserving postischemic OMBF and GFR (686.4 ± 45.2 μl·min−1·g kidney wt−1). These beneficial effects of CoCl2 on ischemic acute renal failure seem to be due to HO-1 induction, because they were abolished by stannous mesoporphyrin, a HO inhibitor. In conclusion, HO-1 induction has a protective effect on ischemic renal failure that seems to be partially mediated by decreasing the excessive production of NO with the subsequent reduction in peroxynitrite formation observed during ischemia.

The covid-19 resulted in broad range of spread throughout the world in which India has also became a prey of it and in this situation the means of media is extensively inϑluencing the mentality of the people. Media always played a role of loop between society and sources of information. In this epidemic also media is playing a vital role in shaping the reaction in ϑirst place for both good and ill by providing important facts regarding symptoms of Corona virus, preventive measures against the virus and also how to deal with any suspect of disease to overcome covid-19. On the other hand, there are endless people who spread endless rumours overs social media and are adversely affecting life of people but we always count on media because they provide us with valuable answers to our questions, facts and everything in need. Media always remains on top of the line when it comes to stop the out spread of rumours which are surely dangerous kind of information for society. So on our side we should react fairly and maturely to handle the situation to keep it in the favour of humanity and help government not only to ϑight this pandemic but also the info emic.

Abstract The COVID-19 pandemic has brought significant challenges to healthcare systems worldwide, and in Africa, given the lack of resources, they are likely to be even more acute. The usefulness of Traditional African Healers in helping to mitigate the effects of pandemic has been neglected. We argue from an ethical perspective that these healers can and should have an important role in informing and guiding local communities in Africa on how to prevent the spread of COVID-19. Particularly, we argue not only that much of the philosophy underlying Traditional African Medicine is adequate and compatible with preventive measures for COVID-19, but also that Traditional African Healers have some unique cultural capital for influencing and enforcing such preventive measures. The paper therefore suggests that not only given the cultural context of Africa where Traditional African Healers have a special role, but also because of the normative strength of the Afro-communitarian philosophy that informs it, there are good ethical reasons to endorse policies that involve Traditional Healers in the fight against COVID-19. We also maintain that concerns about Traditional African Healers objectionably violating patient confidentiality or being paternalistic are much weaker in the face of COVID-19.

Introduction: Inflammation is a fundamental phenomenon in heart failure, but the prognostic or therapeutic role of markers such as interleukin-6 (IL-6) has not yet been clarified. The objective of this study is to describe the clinical profile of patients with elevated IL-6 and determine if they have worse clinical outcomes. Methods: A retrospective c.ohort observational study including 78 patients with heart failure followed up at the Heart Failure Outpatient Clinic of the Internal Medicine Department. IL-6 was determined in all patients, who were then assigned into two groups according to IL-6 level (normal or high). Clinical and prognostic data were collected to determine the differences in both groups. Results: The average age was 79 years, 60% female. A total of 53.8% of the patients had elevated IL-6 (group 2). Patients with elevated IL-6 presented more frequently with anemia mellitus (64.3% vs. 41.7%; p = 0.046), atrial fibrillation (83.3% vs. 61.9% p = 0.036), dyslipidemia (76.2% vs. 58.2%; p = 0.03), higher creatinine levels (1.35 mg/dL vs. 1.08 mg/dL; p = 0.024), lower glomerular filtration rate (43.6 mL/min/m2 vs. 59.9 mL/min/m2; p = 0.007), and anemia 25% vs. 52.4% p = 0.014. The factors independently associated with the increase in IL-6 were anemia 3.513 (1.163–10.607) and renal failure 0.963 (0.936–0.991), p < 0.05. Mortality was higher in the group with elevated IL-6 levels (16% vs. 2%; p = 0.044) with a log-rank p = 0.027 in the Kaplan–Meier curve. Conclusion: Patients with heart failure and elevated IL-6 most often have atrial fibrillation, diabetes mellitus, dyslipidemia, anemia, and renal failure. In addition, mortality was higher and a tendency of higher hospital admission was observed in stable HF patients with elevated IL-6.
