Proteolytic Activation of the Epithelial Sodium Channel
Epithelial sodium channel (ENaC) are integral to maintaining salt and water homeostasis in various biological tissues, including the kidney, lung, and colon. They enable the selective reabsorption of sodium ions, which is a process critical for controlling blood pressure, electrolyte balance, and overall fluid volume. ENaC activity is finely controlled through proteolytic activation, a process wherein specific enzymes, or proteases, cleave ENaC subunits, resulting in channel activation and increased sodium reabsorption. This regulatory mechanism plays a pivotal role in adapting sodium transport to different physiological conditions.

Pediatric Anaplastic Lymphoma Kinase-Positive Anaplastic Large Cell Lymphoma
Anaplastic lymphoma kinase (ALK)-positive anaplastic large cell lymphoma (ALCL) is an aggressive T-cell lymphoma characterized by large T-cells with strong CD30 and ALK expression. Although conventional chemotherapy is effective in most patients, approximately 30% experience a relapse or refractory disease and have a poor prognosis. Several risk factors associated with poor prognosis have been identified in pediatric ALK-positive ALCL. These include morphological patterns with the small cell variant or lymphohistiocytic variant, leukemic presentation, the presence of minimal disseminated disease, or involvement of the central nervous system. Relapsed or refractory ALK-positive ALCL is often resistant to conventional chemotherapy; therefore, salvage therapy is required. In recent years, targeted therapies such as ALK inhibitors and brentuximab vedotin (BV) have been developed. ALK inhibitors block the continuous activation of ALK kinase, a driver mutation that leads to cell proliferation in ALK-positive ALCL. Additionally, BV is an antibody–drug conjugate that targets CD30-positive cells. Both ALK inhibitors and BV have displayed dramatic effects in chemoresistant ALK-positive ALCL. Weekly vinblastine treatment and hematopoietic stem cell transplantation have also been reported to be effective therapies.

Osteopontin in the Inflammatory Responses of Alzheimer’s Disease
Osteopontin (OPN), an inflammatory cytokine and biomarker of alzheimer’s disease (AD), is implicated in Aβ clearance and toxicity, microglial activation, and inflammation, and is considered to be a potential therapeutic target.

Phase II Drug-Metabolizing Enzyme and Drug Transporter Expression
Sparse and conflicting evidence exists regarding the localization, expression, and regulation of phase II drug-metabolizing enzymes and drug transporters across gestational stages. To resolve the uncertainties and assumptions in current knowledge, additional pharmacokinetic (PK) data and clinical pharmacology research are required to understand drug metabolism and transport in the pregnant woman and in the placenta.

Early Complications of Esophagectomy
Esophagectomy is a technically complex operation performed for both benign and malignant esophageal disease. Medical and surgical advancements have led to improved outcomes in esophagectomy patients over the past several decades; however, surgeons must remain vigilant as complications happen often and can be severe. Post-esophagectomy complications can be grouped into early and late categories.

Computer-Aided Drug Design and Drug Discovery
In the dynamic landscape of drug discovery, Computer-Aided Drug Design (CADD) emerges as a transformative force, bridging the realms of biology and technology. The core principle underpinning CADD are the utilization of computer algorithms on chemical and biological data to simulate and predict how a drug molecule will interact with its target—usually a protein or DNA sequence in the biological system.

Complications of Diabetes and Diabetic Foot
Globally, a leg is amputated approximately every 30 seconds, with an estimated 85 percent of these amputations being attributed to complications arising from diabetic foot ulcers (DFU), as stated by the American Diabetes Association. Peripheral arterial disease (PAD) is a risk factor resulting in DFU and can, either independently or in conjunction with diabetes, lead to recurring, slow-healing ulcers and amputations.

Clinical Diagnosis and Treatment of Chronic Pain
Pain medicine is a multidisciplinary and multimodal approach to help patients manage chronic pain. The definition of chronic pain has evolved to become less “non-specific” and to help aid in the proper classification of the disease. While the term can often be too generalized when describing a wide array of conditions, the future of chronic pain diagnosis and treatment is becoming more personalized and precision based. More optimized and specific chronic pain diagnoses can help avoid pooling together heterogenous conditions.

Classifications and Treatments for Gliomas
Gliomas pose a significant challenge to neurosurgical oncology because of their diverse histopathological features, genetic heterogeneity, and clinical manifestations. Despite significant advances in understanding the molecular pathways of glioma, translating this knowledge into effective long-term solutions remains a challenge.

Nutritional Interventions in at the Office
Workplace nutrition interventions have garnered attention as a pivotal component of employee well-being and organisational productivity. The narrative synthesis has demonstrated that behavioural and mixed (cognitive-behavioural) interventions are more effective rather than solely cognitive ones. Apart from the employees, employers also should be engaged into designing interventions as well.
