Summary: In an in vivo mouse model of active M. tb infection, diethyl maleate (DEM)-induced glutathione (GSH) deficiency led to increased oxidative stress, impaired granuloma response, and increased M. tb survival. These findings provide insights into how GSH deficiency can interfere with the control of M. tb infection.

Summary: This study presents a mass spectrometry imaging (MSI) approach for mapping thiol compounds on brain tissue sections. The developed method allows for selective and rapid detection of glutathione (GSH) synthesis and metabolic pathway related metabolites. The method also enables quantitative detection of exogenous N-acetylcysteine tissue sections, with a detection limit of 0.05 ng. The capabilities of the method are demonstrated through mapping thiol compounds on brain tissue from a chronic social defeat stress (CSDS) depression model mice.

Summary: The study investigates the biochemical and pathophysiological changes caused by medwakh smoking and examines the salivary metabolomics profile of medwakh smokers. Analysis of saliva samples reveals 37 uniquely and differentially abundant metabolites and 20 differentially altered metabolic pathways in medwakh smokers. The study highlights the association of altered redox homeostasis, metabolic pathways, antioxidant system, and CRP levels with the distinctive saliva metabolomics profile in medwakh smokers. Further research is needed to explore the diagnostic utility of these altered metabolites in larger cohorts.

Summary: This study investigated the effects of targeting the CXCR4 receptor as an alternative strategy for treating rheumatoid arthritis (RA). The results showed that CXCR4 targeting with CB effectively inhibited the production of key inflammatory cytokines by monocytes and led to a reduction in disease progression in a mouse model of collagen-induce arthritis. These findings suggest that targeting CXCR4 with CB could be a promising therapeutic option for chronic and viral-induced inflammatory diseases, including RA.

Summary: Atherosclerosis is a major pathological process of cardiovascular diseases, which can begin early in life and remain silent before symptoms manifest. The formation of foamy macrophages due to dysregulated lipid metabolism is important in atherosclerotic plaque development. Current pharmacotherapy for atherosclerosis is limited, but "Lipidom" has shown potential with its antioxidant, lipid-lowering, and anti-inflammatory properties. This study aimed to characterize the pharmacological effects of "Lipidom" using experimental models.

Summary: SARS-CoV-2 infection causes severe respiratory distress syndrome and inflammatory complications, with increased severity in older patients and those with comorbidities. The virus may take advantage of age-related abnormalities in cellular redox balance. Changes in cellular metabolism and Cys/GSH fluxes, as well as ER stress pathway activation, are associated with the pro-oxidant effects of SARS-CoV-2 infection. Antiviral drugs and cytoprotective agents like N-acetyl cysteine may help limit the cytopathic effects of the virus and restore tissue homeostasis post-infection.

Summary: Intense physical exercise leads to increased production of reactive oxygen and nitrogen species. This study examined the effects of dipeptide intake combined with exercise on the oxi-antioxidant response. The results showed that dipeptide intake led to a significant increase in the NO/H2O2 ratio after exercise, indicating enhanced antioxidant status. Additionally, dipeptides were found to reduce C-reactive protein levels, suggesting their anti-inflammatory properties. These findings suggest that dipeptides have potential in reducing oxidative stress and inflammation in physically active individuals.

Summary: The increased awareness of health effects from micro- and nanoplastics pollution has led to a significant amount of studies. International efforts are being made to understand the hazard of these pollutants. However, there is a limited number of studies directly measuring human exposure to micro- and nanoplastics and its impact on health. This review provides an overview of the current research on biomarkers of oxidative stress, inflammation, and genotoxicity related to exposure, using various models. Both in vitro and in vivo models suggest that increased oxidative stress and inflammation are the main mechanisms leading to adverse effects.

Summary: This study aimed to establish an extraction method for the most abundant phenolic compounds in Petroselinum crispum leaves. The extraction conditions were optimized using response surface methodology and ultrasound-assisted extraction. The phenolic compounds in the extracts were accurately quantified using HPLC-PDA, and their identification was performed using UPLC-Q-TOF MS. The extracts obtained under the optimal conditions contained a sufficient amount of phenolic compounds for use in the production of functional foods.

Summary: Atherosclerosis is a progressive vascular disease caused by inflammation and oxidation. The Mediterranean diet, especially olive oil, has been recognized as a healthy dietary pattern. This review focuses on the effects of olive oil microconstituents in atherosclerosis, particularly their inhibitory activity against Platelet-Activating Factor (PAF) actions. The anti-atherogenic effect of olive oil is attributed to the synergistic action of its microconstituents, including polar lipids, polyphenols, and alpha-tocopherol. Daily moderate intake of olive oil in a balanced diet is significant for healthy adults.

Summary: This study investigated the relationship between selenium distribution in plasma and cardiovascular disease. The results showed an inconclusive relationship between selenium and cardiovascular disease, especially in terms of different selenospecies. Total selenium in selenoproteins was positively associated with a 10-year relative risk of cardiovascular disease. Individuals with high selenium but low glutathione peroxidase 3 had a higher cardiovascular risk.

Summary: Olive oil, the main source of polyphenols in the Mediterranean diet, has been found to reduce cardiometabolic risk factors. However, the consumption of refined olive oil has led to a decrease in polyphenol intake. This study investigated the effects of enhancing refined olive oil with orange peel extract on postprandial lipemia, glycemia, and oxidative stress in individuals at risk of cardiometabolic problems. The results showed a significant reduction in LDL-cholesterol after consuming the functional olive oil, indicating its potential to modulate cardiometabolic risk factors.
