Summary: Megakaryocytes are important members of the hematopoietic system, responsible for regulating vascular homeostasis through platelets. The process of megakaryopoiesis generates mature megakaryocytes which release proplatelets into blood vessels. Nitric oxide (NO) plays a modulatory role in hematopoiesis and hemostasis. This review summarizes the effect of NO and its signaling on megakaryopoiesis and thrombopoiesis under physiological and pathophysiological conditions.

Summary: This study investigated differential DNA-methylation between individuals with severe AUD and controls in various brain regions, identifying novel CpG-sites and regions implicated in AUD. Results suggest potential epigenetic correlates of AUD in specific brain regions, particularly highlighting immune-related pathways in the ventral striatum. This study provides a significant basis for further exploration of the epigenetic mechanisms underlying AUD.

Summary: Kidney transplantation is the preferred treatment for patients with kidney failure. However, ischemia-reperfusion injury (IRI) poses a significant challenge to the long-term success of this intervention. Nitric oxide (NO) has emerged as a potential candidate for mitigating IRI and preventing graft rejection in kidney transplantation. This review provides an overview of the sources and protective effects of endogenous and exogenous NO in kidney transplantation.

Summary: This paper describes the design, synthesis, and biological evaluation of selective inhibitors of inducible nitric oxide synthase (iNOS). The most potent and selective compound showed inhibitory activity against iNOS without undesirable cardiovascular effects. In silico analysis predicted good drug-likeness properties for promising compounds, which also exhibited adequate cell viability. Docking studies revealed a unique binding mode for one compound and explained its selectivity towards iNOS.

Summary: Bacopa monnieri is a potent Indian medicinal plant with various pharmacological activities, including anti-inflammatory and neuroprotective effects. This study focused on the anti-inflammatory potential of its bioactive compounds and their interaction with inflammation-related genes. The docking results revealed that quercetin showed significant binding energies with inflammatory genes. In vitro experiments demonstrated that quercetin effectively reduced nitric oxide production and downregulated COX-2 and iNOS gene expression in LPS-stimulated macrophages.

Summary: The study found that 1,3-dicaffeoylquinic acid (1,3-diCQA) from Arctium lappa root extract has antidepressant effects by activating the ERK-CREB-BDNF pathway and increasing nNOS levels in the hippocampus of menopausal mice. This effect is independent of estrogen receptors but can be inhibited by an nNOS inhibitor, suggesting a potential therapeutic target for menopausal depression.

Summary: In this study, differences in gyrification patterns between major depressive disorder (MDD) patients and healthy controls (HCs) were investigated, and the association of these patterns with plasma brain-derived neurotrophic factor (BDNF) levels and depressive symptoms was explored. The results suggest that abnormal early cortical neurodevelopment may mediate vulnerability to MDD, independent of plasma BDNF levels and depressive symptoms.

Summary: NOS-derived NO plays a critical role in protecting cyanobacteria from oxidative burst and maintaining their physiological balance. Addition of L-NAME inhibitor reduces NO accumulation, while addition of L-arginine increases NO synthesis. Inhibition of NOS leads to decreased growth and metabolic activity of cyanobacteria, as well as decline in photopigments, PSII efficiency, loss in membrane integrity and DNA damage, ultimately resulting in cell death.

Summary: Vascular tone regulation by nitric oxide is a crucial physiological function, with endothelial dysfunction potentially being an underlying cause of hypertension. Increasing eNOS activity reduces blood pressure, while decreasing activity has the opposite effect. These findings have important implications for pre-hypertensive treatment.

Summary: This study compared the metabolomic profiles of patients with major depressive disorder (MDD) with and without type 2 diabetes mellitus. The results showed that there may be differences in serum metabolite patterns among different groups and that type 2 diabetes mellitus could affect metabolic pathways and alter the distribution of serum metabolites in patients with MDD.

Summary: The study aimed to find a new method of evaluation and surrogate markers for diffuse neuropsychiatric SLE (NPSLE). Retrospective evaluation revealed that many patients with active SLE have subclinical depression, and MADRS evaluation is useful in detecting them. Additionally, the decrease in CSF levels of HVA, SDF-1 alpha, and SCGF-1 beta reflects the same pathology, and these may serve as surrogate markers.

Summary: This study investigated the volumetric changes of thalamic subregions and their nuclei in drug-naive, first-episode MDD patients, as well as the association between thalamic nuclei volumes and HAM-D scores. The results revealed significant volume reductions in the left whole thalamus and several thalamic nuclei in the MDD group compared to healthy controls, and weak negative correlations between thalamic nuclei volumes and HAM-D scores. These findings provide preliminary insights into the thalamic structural changes in drug-naive, first-episode MDD patients.

Summary: This study compared the changes in serum BDNF concentrations in first-episode, drug-naive patients with major depression treated with antidepressants between treatment-response and treatment-nonresponse groups. The results showed that the serum BDNF levels changed significantly in the responder group but not in the non-responder group. The measurement of serum BDNF has the potential to be a useful predictor of pharmacotherapy in patients with first-episode, drug-naive major depression.

Summary: This study examined the association between miRNA levels in extracellular vesicles (EVs) from serum and the severity of Major Depression (MD). The expression levels of hsa-miR-6813-3p and hsa-miR-2277-3p were found to be significantly downregulated with increasing depression severity of MD. These miRNAs could serve as novel biomarkers for MD and contribute to understanding its pathophysiology.

Summary: This study aimed to explore the reliability of salivary mBDNF as a biomarker for psychological distress in healthcare workers and the relationship between salivary and plasma mBDNF levels as well as their correlation with age, sex, BMI, and exercise habits. The findings indicate that salivary mBDNF can be accurately measured noninvasively in healthcare workers, but did not show correlation with K6 and plasma mBDNF. Future studies with a larger sample size and diverse populations are needed to further investigate these relationships.
