Summary: The brain has the ability to shift its gears between wakefulness and sleep, with information processing and behavior dominating in wakefulness and homeostatic functions prevailing during sleep. The brain relies on the glymphatic system, a fluid system comprised of the cerebrospinal fluid and perivascular spaces formed by astrocytic vascular endfeet, to clear waste products and maintain homeostasis. This system is especially active during sleep, driven by the cardiac cycle, respiration, and slow vasomotion.

Summary: The uptake and extrusion of calcium into and from the mitochondrial matrix have significant effects on cellular metabolism, signaling, and survival. Disruption of mitochondrial calcium cycling is associated with various diseases and inherited neuromuscular disorders. This review provides an overview of the molecular machinery involved in calcium flux across the inner mitochondrial membrane and discusses the physiological implications and potential therapeutic interventions for diseases characterized by aberrant calcium handling. Critical unanswered questions regarding the biology of calcium flux are also highlighted.

Summary: Ca2+-release channels are membrane proteins that control the release of Ca2+ from the endoplasmic and sarcoplasmic reticulum. They are activated by cytosolic Ca2+ and have a common architecture, with additional modules in the cytosolic region for ryanodine receptors (RyRs). Their regulation involves the binding of proteins and small molecules, with major triggers including IP3 and membrane depolarization. Electron microscopic studies have provided valuable insights into their structure and mechanisms, including the binding of auxiliary proteins, regulation of channel opening, and disease-associated mutations.

Summary: Understanding the transient dynamics of the autonomic nervous system during fear learning is crucial for the treatment of fear-related disorders. In this study, a novel frequency-domain analysis of heart rate was performed to investigate the physiological processes underlying fear learning. The results revealed that fear learning led to a transient heart rate deceleration and increased parasympathetic (vagal) activity, indicating the involvement of cardiac vagal dynamics in fear learning.

Summary: Lactate shuttling is essential in energy substrate production and distribution through cell-cell and intracellular shuttles. Mitochondrial respiration serves as the physiological pathway for lactate disposal, and repeated lactate exposure from regular exercise adapts processes like mitochondrial biogenesis.

Summary: Sepsis is expected to have a significant impact on public health and cost as its prevalence increases. Factors contributing to the increased prevalence include aging population, immunomodulatory treatments, and immune-suppressing therapies. Sepsis-induced immunosuppression has been recognized as a predisposing factor in susceptibility to secondary infections and mortality. This review discusses the mechanisms of sepsis-induced immunosuppression, biomarkers for impaired immunity, immune-enhancing strategies, and ongoing therapeutics in sepsis patients. Furthermore, future challenges and the need for personalized immunotherapy are highlighted.

Summary: The mucus clearance system is the dominant mechanical defense system of the human lung, clearing mucus through cilia and airflow. Mucus transport rates are heavily dependent on mucus concentration and can be accurately predicted by a model. Fluid for mucus hydration is generated through epithelial fluid transport. Diseases can cause mucus hyperconcentration and obstructive plaques.

Summary: Metastasis of tumor cells is a significant challenge in cancer patients, and the activation of nuclear factor-kappaB (NF-kappa B) plays a crucial role in regulating the epithelial-to-mesenchymal transition (EMT). The activation of NF-kappa B enhances the invasive properties of tumor cells through inducing EMT mechanism, and this has been confirmed in various cancers.
