A large body of evidence indicates that chronic obstructive pulmonary disorder (COPD) is accompanied by oxidative stress and inflammatory and genetic pathways. Epidemiological studies indicate that COPD is a major cause of mortality and morbidity in the world. Recent research development in COPD focuses on accelerated aging and various oxidative stress biomarkers. It involves the clinical manifestation of the disease process and may also contain biochemical, immunological, physiological, morphological, and genetic aspects that add to the progressiveness of the disease. Herein, we summarize findings that highlight the role of dimensions of COPD in the investigation of oxidative stress, inflammatory responses, genetic and epigenetic studies, and pharmacological and dietary antioxidant intervention.

Effects of abdominal, vaginal, and laparoscopic hysterectomies on total oxidant/antioxidant levels: A prospective observational study.
Medicine (Baltimore)

Department of Biochemistry, Republic of Turkey Ministry of Health Taksim Training and Research Hospital, İstanbul, Turkey.
This prospective observational study aimed to compare abdominal hysterectomy (AH), vaginal hysterectomy (VH), and total laparoscopic hysterectomy (TLH) in terms of oxidative stress (OS) by measuring serum levels of total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI). Of the 3 groups, namely, AH, VH, and TLH, 22 patients were enrolled in each to investigate the aim of the study mentioned above. Patient demographics, clinical and surgical characteristics, and preoperative and postoperative (0th and 24th hours) serum TAS, TOS, and OSI levels were investigated.

Objective: The pathophysiology of delayed cerebral ischemia (DCI) is not fully elucidated. The lack of accurate diagnostic tools increases the probability of delayed diagnosis and timely treatment. The authors assessed the relationship of 8-iso-prostaglandin F2α (F2-IsoP) and oxidative stress biomarkers, nitric oxide synthase 3 (NOS3) and nicotinamide adenine dinucleotide phosphate (NADPH), with DCI after aneurysmal subarachnoid hemorrhage (aSAH).

20% acute pancreatitis (AP) develops into severe AP (SAP), a global health crisis, with an increased mortality rate to 30%-50%. Mitochondrial damage and immune disorders are direct factors, which exacerbate the occurrence and progression of AP. So far, mitochondrial and immunity injury in SAP remains largely elusive, with no established treatment options available.

Reduced nicotinamide adenine dinucleotide phosphate (NADPH) is a crucial reducing cofactor for reductive biosynthesis and protection from oxidative stress. To fulfill their heightened anabolic and reductive power demands, cancer cells must boost their NADPH production. Progrowth and mitogenic protein kinases promote the activity of cytosolic NAD kinase (NADK), which produces NADP, a limiting NADPH precursor.

Circadian rhythm disruption, commonly caused by factors such as jet lag and shift work, is increasingly recognized as a critical factor impairing wound healing. Although melatonin is known to regulate circadian rhythms and has potential in wound repair, its clinical application is limited by low bioavailability. To address these challenges, we developed an alginate-based dual-network hydrogel as a delivery system for melatonin, ensuring its stable and sustained release at the wound site.
