Phytofabricated bimetallic synthesis of silver-copper nanoparticles using Aerva lanata extract to evaluate their potential cytotoxic and antimicrobial activities.

In this study, we demonstrate the green synthesis of bimetallic silver-copper nanoparticles (Ag-Cu NPs) using Aerva lanata plant extract. These NPs possess diverse biological properties, including in vitro antioxidant, antibiofilm, and cytotoxic activities. The synthesis involves the reduction of silver nitrate and copper oxide salts mediated by the plant extract, resulting in the formation of crystalline Ag-Cu NPs with a face-centered cubic structure. Characterization techniques confirm the presence of functional groups from the plant extract, acting as stabilizing and reducing agents. The synthesized NPs exhibit uniform-sized spherical morphology ranging from 7 to 12 nm. They demonstrate significant antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa, inhibiting extracellular polysaccharide secretion in a dose-dependent manner. The Ag-Cu NPs also exhibit potent cytotoxic activity against cancerous HeLa cell lines, with an inhibitory concentration (IC50) of 17.63 µg mL-1. Additionally, they demonstrate strong antioxidant potential, including reducing capability and H2O2 radical scavenging activity, particularly at high concentrations (240 µg mL-1). Overall, these results emphasize the potential of A. lanata plant metabolite-driven NPs as effective agents against infectious diseases and cancer.

The Efficacy of S-Adenosyl Methionine and Probiotic Supplementation on Depression: A Synergistic Approach.

Depression is a common and serious health issue affecting around 280 million people around the world. Suicidal ideation more frequently occurs in people with moderate to severe depression. Psychotherapy and pharmacological drugs are the mainstay of available treatment options for depressive disorders. However, pharmacological options do not offer complete cure, especially in moderate to severe depression, and are often seen with a range of adverse events. S-adenosyl methionine (SAMe) supplementation has been widely studied, and an impressive collection of literature published over the last few decades suggests its antidepressant efficacy. Probiotics have gained significant attention due to their wide array of clinical uses, and multiple studies have explored the link between probiotic species and mood disorders. Gut dysbiosis is one of the risk factors in depression by inducing systemic inflammation accompanied by an imbalance in neurotransmitter production. Thus, concomitant administration of probiotics may be an effective treatment strategy in patients with depressed mood, particularly in resistant cases, as these can aid in dysbiosis, possibly resulting in the attenuation of systemic inflammatory processes and the improvement of the therapeutic efficacy of SAMe. The current review highlights the therapeutic roles of SAMe and probiotics in depression, their mechanistic targets, and their possible synergistic effects and may help in the development of food supplements consisting of a combination of SAMe and probiotics with new dosage forms that may improve their bioavailability.

COVID-19 Pandemic: Epidemiology, Etiology, Conventional and Non-Conventional Therapies.

Coronavirus disease 2019 (COVID-19), which reported in an outbreak in 2019 in Wuhan, Hubei province, China, is caused by the SARS-CoV-2 virus. The virus belongs to the beta-coronavirus class, along with the Middle East Respiratory Syndrome coronavirus and Severe Acute Respiratory Syndrome coronavirus. Interestingly, the virus binds with angiotensin-converting enzyme-2 found in host cells, through the spike (S) protein that exists on its surface. This binding causes the entry of the virus into cells of the host organism. The actual mechanism used by the COVID-19 virus to induce disease is still speculative. A total of 44,322,504 cases, a 1,173,189 death toll and 32,486,703 recovery cases have been reported in 217 countries globally as of 28 October 2020. Symptoms from the infection of the virus include chest pain, fever, fatigue, nausea, and others. Acute respiratory stress syndrome, arrhythmia, and shock are some of the chronic manifestations recorded in severe COVID-19. Transmission is majorly by individual-to-individual through coughing, sneezing, etc. The lack of knowledge regarding the mechanism of and immune response to the virus has posed a challenge in the development of a novel drug and vaccine. Currently, treatment of the disease involves the use of anti-viral medications such as lopinavir, remdesivir, and other drugs. These drugs show some efficacy in the management of COVID-19. Studies are still on-going for the development of an ideal and novel drug for treatment. In terms of natural product intervention, Traditional Chinese Medicines (TCM) have been employed to alleviate the clinical manifestation and severity of the disease and have shown some efficacy. This review presents an updated detailed overview of COVID-19 and the virus, concerning its structure, epidemiology, symptoms and transmission, immune responses, and current interventions, and highlights the potential of TCM. It is anticipated that this review will further add to the understanding of COVID-19 and the virus, hence opening new research perspectives.

Effect of Sheetali pranayama on cardiac autonomic function among patients with primary hypertension - A randomized controlled trial.

BACKGROUND: Sheetali pranayama is a cooling pranayama practiced for hypertension (HTN). The effects of Sheetali pranayama, as a solitary intervention on cardiovascular and autonomic changes in hypertension is unknown. MATERIALS AND METHODS: The current study was conducted on 100 patients with HTN, randomly allocated to HTN with pranayama (Intervention group,n = 50) and HTN without pranayama (control group,n = 50) group. The intervention group practiced Sheetali pranayama for a period of 3 months. Blood pressure and HRV was assessed before and after the intervention. RESULTS: Intervention group showed a significant (P < 0.05) reduction in blood pressure variables when compared to the control group. In short term HRV, time and frequency domain parameters showed parasympathetic dominance (P < 0.05) in the intervention group. CONCLUSION: Sheetali pranayama significantly reduces blood pressure in patients with HTN and improved heart rate variability. Sheetali pranayama could thus be practiced in addition to regular medications for the efficacious management of HTN.

Plumbagin engenders apoptosis in lung cancer cells via caspase-9 activation and targeting mitochondrial-mediated ROS induction.

Plumbagin is a naturally-derived phytochemical which exhibits promising medicinal properties, including anticancer activities. In the present study, the anticancer potential of plumbagin has been demonstrated in lung cancer cells by targeting reactive oxygen species (ROS) and the intrinsic mitochondrial apoptotic pathway. Plumbagin showed impressive cytotoxic, anti-proliferative, and anti-migratory activities with IC50 3.10 ± 0.5 µM and 4.10 ± 0.5 µM in A549 and NCI-H522 cells, respectively. Plumbagin treatment significantly reduced the size of A549 tumor spheroids in a concentration-dependent manner. Plumbagin enhanced ROS production and arrested lung cancer cells in S and G2/M phase. Expression of antioxidant genes such as glutathione S-transferase P1 and superoxide dismutase-2 were found to be upregulated with plumbagin treatment in A549 cells. Plumbagin induced dissipation in mitochondrial membrane potential and affected the expression of intrinsic apoptotic pathway proteins. Increased expression of cytochrome c promotes the activation of pro-apoptotic protein Bax with decreased expression of anti-apoptotic protein Bcl-2. Further, plumbagin activated the mitochondrial downstream pathway protein caspase-9 and caspase-3 leading to apoptosis of A549 cells. Collectively, plumbagin could be a promising future phytotherapeutic candidate for lung cancer treatment via targeting intrinsic mitochondrial apoptotic pathway and ROS.
