On March 11, 2020, the World Health Organization declared the outbreak of the novel SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) as a global pandemic. At the center of SARS-CoV-2 is the activation of inflammatory markers; remarkably, interleukin 6 and C-reactive protein seem to be consistently elevated in patients with SARS-CoV-2. Here, we showed that increased systemic C-reactive protein and interleukin 6 are common biomarkers of both severe COVID-19 and DSM-5-defined disorders.

Impediment of mitochondrial oxidative phosphorylation results in a shift toward anaerobic respiration and lactate production. Elevated CNS lactate levels in adults with BD inform the need to evaluate lactate in peripheral samples and early in the course of BD.

The mitochondrial complex I enzyme is one of the main sites of ROS generation and is implicated in many BD pathophysiologies. Despite advances in therapeutics for BD management, conventional pharmacotherapy still cannot efficiently control neuronal redox imbalance and mitochondrial dysfunction.

Background: extract (AAE) is a polyphenol-rich extract that has gained interest as a natural anticancer agent. Recent work suggests that AAE induces oxidative damage and apoptosis through its action on decreasing complex I activity of the mitochondrial Electron Transport Chain (ETC).
Aims And Methods: In the present study, we aimed to further examine the specific targets by which AAE exerts proapoptotic effects in HEp-2 cancer cells.
Depression and anxiety are prevalent in patients with heart failure (HF). Reduced ejection fraction (EF) and increased N-terminal-prohormone B-type natriuretic peptide (NT-proBNP) have been shown to be independently associated with depressive symptoms and may therefore increase HF disease progression and mortality. This study evaluated whether NT-proBNP mediated the impact of reduced EF on depressive and anxiety symptoms in patients with HF.

Bipolar disorder (BD) is a debilitating mood disorder with no specific biological marker. No novel treatment has been developed specifically for BD in the last several decades. Although the pathophysiology of BD remains unclear, there is strong evidence in the literature supporting the role of mitochondrial dysfunction in BD.

Evidence suggest that there is a two-way relationship between depression and CVD. Inflammation is implicated in the pathophysiology of both conditions, thus representing a central candidate mediating the link between these disorders.

Animal studies support this association and demonstrate that maternal immune activation (MIA) changes brain morphology and inflammatory cytokines in the adult offspring. Evidence for changes in inflammatory cytokines is also demonstrated in human post-mortem brain and peripheral blood studies from subjects with psychiatric disorders.

Several current studies describe an association between psychiatric illness and mitochondrial dysfunction and consequent cellular modifications, including lipid, protein, and DNA damage, caused by cellular oxidative stress.

These illnesses are complex and heterogeneous, which is reflected by the complexity of the processes regulating mitochondrial function. Mitochondria are typically associated with energy production; however, dysfunction of mitochondria affects not only energy production but also vital cellular processes, including the formation of reactive oxygen species, cell cycle and survival, intracellular Ca(2+) homeostasis, and neurotransmission.

As this is a state-related phenomenon, identifying regulators responsible for this phasic dysregulation has the potential to uncover key elements in the pathophysiology of BD. Given the evidence suggesting mitochondrial complex I dysfunction in BD, we aimed to identify the main regulators of complex I in BD by reviewing the literature and using the published microarray data to examine their gene expression profiles.

Although antioxidants, redox modulations, and neuropsychiatric disorders have been widely studied for many years, the field would benefit from an integrative and corroborative review. Our primary objective is to delineate the biological significance of compounds that modulate our redox status (i.e.

Human papillomaviruses (HPVs) are frequently detected in a variety of lesions in the oral mucosa and upper respiratory tract. The pathogenesis in these areas is not as clearly elucidated as in other anatomical regions, but most experts agree that HPVs are responsible for the commonly observed benign lesions, such as squamous papillomas, verruca vulgaris and recurrent respiratory papillomatosis. Transformation of these benign lesions is well described, but it is not clear what role the virus plays, if any, in carcinogenesis.
