Background: Systemic inflammation is associated with severe coronavirus disease. Hyponatremia can be caused by inflammation related to non-osmotic stimuli. Objectives: This study was conducted to ...investigate hyponatremia status and interleukin 6 concentration as well as their possible relationship in COVID-19 patients compared to healthy people. Methods: In this cross-sectional study, 24 COVID-19 patients and 24 healthy individuals referred to hospitals in Hamadan were included in the study in order to evaluate the relationship between hyponatremia and inflammation. The study was conducted after receiving ethical approval and informed consent from the participants. Complete blood count (CBC), inflammatory markers, electrolytes, creatinine, liver enzymes, ferritin, albumin, and D-dimer were measured using Selectra-Pro XI autoanalyzer, Pars Azmoun kits, and Human Interleukin 6 ELISA Kit Catalog MBS760693. All analyses were performed at a significance level of 0.05. Results: In this study, there was no statistically significant difference in age and gender between 24 healthy people and 24 participating patients (P>0.05). The level of electrolytes such as sodium, potassium, magnesium, calcium, and phosphorus was significantly decreased in patients with COVID-19 compared to controls (P<0.001). The level of inflammatory markers, ferritin, albumin, D-dimer, and liver enzymes in the patient group was significantly increased compared to the control group (P<0.01). Conclusion: The results of this study showed a higher incidence of hyponatremia and an increased level of interleukin-6 in COVID-19 patients. It seems that the use of strategies to reduce inflammation will help in the proper management of the disease.
Curcumin has been isolated from the rhizomes of Curcuma longa. Over the years, it has shown outstanding therapeutic potential in various human disorders, including cancers.
The aim is to study ...curcumin's effects on the apoptosis signaling pathway in the head and neck squamous cell carcinoma (HNSCC) cell line HN5.
The cytotoxicity of curcumin on HN5 cells were assessed. In addition, HN5 cells were also treated with curcumin to evaluate its effect on the caspase-8, -9, Bcl-2, Bax, and Stat3 gene expressions.
The results exhibited that cell viability reduced following curcumin treatment in a concentration- dependent manner. Curcumin treatment caused decreased expression of Bcl2, with simultaneous upregulation of the Bax/Bcl2 ratio. Curcumin increased caspase-9 expression, did not affect caspase-8, and decreased Stat3 expression. The induction of the mitochondria-dependent apoptosis pathway of curcumin happened by modulating the expression of Bcl2 and Bax genes, resulting in the caspase-9 activation. Furthermore, curcumin decreased the expression of the Stat3 in HN-5 cells.
In conclusion, curcumin showed marked anticancer effects in the HN-5 cell line by modulating Stat-3; Bax/Bcl-2 expression in vitro.
