Persistence of SARS-CoV-2 in COVID-19 patients during the second wave of the pandemic in India.

Introduction: India witnessed the catastrophic second wave of COVID-19 during the summer months of 2021. Many patients with non-resolution of symptoms admitted to dedicated COVID-19 treatment centers required prolonged inpatient care which led to the unavailability of beds for other COVID-19 patients. The objective of this study was to determine the duration of SARS-CoV-2 positivity in moderate and severe COVID-19 patients requiring long-term pulmonary care as well as to find out the association between different variables with the persistence of the virus.

Mitochondrial Dysfunction Contributes To Zinc-induced Neurodegeneration: a Link with NADPH Oxidase.

Mitochondrial dysfunction and nicotinamide adenine dinucleotide phosphate oxidase (NADPH oxidase) are the major sources of augmentation in free radical generation leading to neurodegeneration. Although NADPH oxidase involvement is reported in zinc (Zn)-induced neurodegeneration, contribution of the mitochondrial dysfunction and its association with NADPH oxidase are not known. Therefore, the study was aimed to decipher the role of mitochondrial dysfunction and its link with NADPH oxidase in Zn-induced Parkinsonism.

Postnatal zinc or paraquat administration increases paraquat or zinc-induced loss of dopaminergic neurons: insight into augmented neurodegeneration.

Epidemiological evidences have shown an association of exposure to pesticides or heavy metals with increased incidences of Parkinson's disease (PD) in humans. Exposure to pesticides or metals during the decisive period of the brain development increases the susceptibility of dopaminergic neurons upon re-exposure in adult rodents. However, the effect of early life exposure to pesticide on the heavy metal-induced neurodegeneration or heavy metal on pesticide-induced neurodegeneration is not yet explored.

Association between autophagy and rapid eye movement sleep loss-associated neurodegenerative and patho-physio-behavioral changes.

Rapid eye movement (REM) sleep is a unique physiological process at least expressed in mammals. Its disturbance affects many psycho-somato-physiological processes including cardio-vascular-respiratory systems, brain excitability, neurogenesis, synaptic pruning, and memory consolidation. While it is altered in most neurodegenerative disorders including Alzheimer's disease (AD), Parkinson's disease (PD) and REM sleep behavior disorder (RBD), the detailed mechanism of inducing such action is unknown.

Inhibition of glutathione S-transferase-pi triggers c-jun N-terminal kinase-dependent neuronal death in Zn-induced Parkinsonism.

Oxidative stress is recognized as one of the major wrongdoers in Parkinson's disease (PD) while glutathione S-transferase (GST), an endogenous antioxidant, protects from oxidative stress-induced neurodegeneration. Despite GST-pi (GST-π) encounters the toxic manifestations in PD, its role in zinc (Zn)-induced nigrostriatal dopaminergic neurodegeneration remains elusive. The study aimed to explore the role of GST-π in Zn-induced Parkinsonism and its underlying molecular mechanism.
