Trace metals are essential elements that play key roles in a number of biochemical processes governing human visual physiology health and disease. Several trace metals, such as zinc, have been shown to important the phototransduction process. In spite this, there has little research conducted on direct effect metal pho-toreceptor rhodopsin. current study, we determined several ions, iron, copper, chromium, manganese, nickel conformational stability rho-dopsin. To this aim, analyzed, by means UV-visible fluorescence spectroscopic methods, effects these thermal dark rhodopsin, its active Metarhodopsin II conformation, chromophore regeneration. Our results show copper prevented rhodopsin regeneration slowed down retinal release process after il-lumination. turn, Fe3+, but not Fe2+, increased inactive con-formation whereas ions markedly decreased it. These findings stress role at photoreceptor level, may be useful for development novel therapeutic strategies treat

Disturbances in copper (Cu) homeostasis have been observed diabetes and associated complications. Cu is an essential micronutrient that plays important roles various fundamental biological processes. For example, diabetic cardiomyopathy with elevated levels of the serum tissues. Therefore, targeting may be a novel treatment strategy for This review provides overview physiological metabolism homeostasis, followed by discussion disorders during occurrence progression Finally, we discuss recent therapeutic advances use coordination complexes as treatments complications their potential mechanisms action. contributes to complete understanding role demonstrates broad application prospects Cu-coordinated compounds agents.

Pathological deterioration of mitochondrial function is increasingly linked with multiple degenerative illnesses as a mediator wide range neurologic and age-related chronic diseases, including those genetic origin. Several these diseases are rare, typically defined in the United States an illness affecting fewer than 200,000 people U.S. population, or about one 1600 individuals. Vision impairment due to dysfunction eye prominent feature evident numerous primary common pathophysiology many familiar ophthalmic disorders, macular degeneration, diabetic retinopathy, glaucoma retinopathy prematurity — collection syndromes, disorders significant unmet medical needs. Focusing on metabolic pathway mechanisms, possible roles cuproptosis ferroptosis retinal dysfunction, we shed light potential α-lipoyl-L-carnitine treating diseases. α-Lipoyl-L-carnitine bioavailable mitochondria-targeting lipoic acid prodrug that has shown protecting against degeneration photoreceptor cell loss indications.

Abstract Insulin is commonly used to treat diabetes and undergoes aggregation at the site of repeated injections in diabetic patients. Moreover, also observed during its industrial production transport should be avoided preserve bioavailability correctly adjust glucose levels However, monitoring effect various parameters (pH, protein concentration, metal ions, etc.) on insulin oligomerization state very challenging. In this work, we have applied a novel Surface Plasmon Resonance (SPR)‐based experimental approach solutions conditions, how diffusion coefficient affected by pH presence ions (copper zinc) with unprecedented sensitivity, precision, reproducibility. The reported SPR method, hereby for first time, besides giving insight into phenomena, proved robust determining any biomolecule. A theoretical background given together software description, specially designed fit data. This new way applying represents an innovation bio‐sensing field expanding potentiality instruments well over canonical investigation biomolecular interactions.

Diabetic Retinopathy (DR) is one of the most important microvascular complications diabetes mellitus, which can lead to blindness in severe cases. Mitochondria are energy-producing organelles eukaryotic cells, participate metabolism and signal transduction, regulate cell growth, differentiation, aging, death. Metabolic changes retinal cells epigenetic mitochondria-related genes under high glucose mitochondrial dysfunction induce pathway apoptosis. In addition, mitophagy dynamics also change adaptively. These mechanisms may be related occurrence progression DR, provide valuable clues for prevention treatment DR. This article reviews mechanism DR induced by dysfunction, prospects treatment.

Globally, diabetic retinopathy (DR) and macular edema (DME) are the leading causes of visual loss in working people. Current treatment approaches mostly target proliferative DR DME, such as intravitreal injections antivascular endothelial growth factor agents laser photocoagulation. Before progresses into more severe, sight-threatening stage, patients with early stages disease must get appropriate care. It has been suggested that nutraceuticals, which natural functional foods minimal adverse effects, may help DME. Several vitro vivo studies were carried out over last years, showing potential benefits several nutraceuticals due to their neuroprotective, vasoprotective, anti-inflammatory, antioxidant properties. Although most research is restricted animal models many have low bioavailability, these compounds adjuvate implement conventional therapies. The purpose this review (i) summarize complex pathophysiology underlying DME (ii) examine main natural-derived molecules dietary habits can assist therapies for clinical management

Skeletal muscle senescence is a significant biological process in the aging of body, marked by reduction mass and function. In recent years, there has been growing interest understanding role copper skeletal aging. During various pathological conditions, often exhibits an accumulation excess copper. This abnormal buildup can trigger specific molecular mechanisms that lead to programmed cell death pathways such as apoptosis, pyroptosis, ferroptosis, cuproptosis, well promote aggregation α-synuclein. These effects set off series signal cascades ultimately result metabolic imbalances within fibers, including protein, mitochondrial, satellite dysfunction, leading degeneration abnormalities neuromuscular junctions. forms new pathophysiological mechanism for atrophy. Here, we provide comprehensive analysis functions regulatory network atrophy, exploring potential overload muscles novel roles signaling induced overload. Our goal offer targets therapeutic options improving treating atrophy through chelation strategies clinical settings.
