Therapeutic potential of Bergenin in the management of neurological-based diseases and disorders.

Originally sourced from plants, Bergenin has been used as a medicinal compound in traditional medicine for centuries, and anecdotal reports suggest a wide range of therapeutic uses. Naturally-occurring and lab-synthesized Bergenin, as well as some of its related compounds, have been shown in in vivo and in vitro studies to alter activity of several enzymes and proteins critical in cellular functioning, including reelin, GSK-3ß, Lingo-1, Ten-4, GP-43, Aß 1-42, P-tau, SOD1,2, GPx, Glx1, NQO1, HO1, PPAR-É£, BDNF, VEGF, and STAT6. Additionally, Bergenin alters levels of several cytokines, such as IL-6, IL-1ß, TNF-α, and TGF-ß. Behavioral and cellular effects of Bergenin have been shown to involve PI3K/Akt, NF-κB, PKC, Nrf2, and Sirt1/FOXO3a pathways. These pathways, enzymes, and proteins have been shown to be important in normal neurological functioning, and/or dysfunctions in these pathways and proteins have been shown to be important in several neuro-based disorders or diseases, which suggests that Bergenin could be therapeutic in management of neuropsychiatric conditions or neurological disorders. In preclinical studies, Bergenin has been shown to be useful for the management of Alzheimer's disease, Parkinson's disease, anxiety, depression, addiction, epilepsy, insomnia, stroke, and potentially, state control. Our review aims to summarize current evidence supporting the conclusion that Bergenin could play a role in treating various neuro-based disorders and that future studies should be conducted to evaluate the mechanisms by which Bergenin could exert its therapeutic effects.

Erectile dysfunction from mechanisms to medicines with a focus on the application of topical Minoxidil.

INTRODUCTION: Erectile dysfunction (ED), for multifactorial reasons, is one of the biggest current quandaries among men worldwide and results in other complications such as reduced quality of life of the patient and his sexual partner, impotence, and psychiatric problems. OBJECTIVES: Understanding of disease etiology, penile anatomy, erectile physiology, therapeutic mechanisms, and effective molecular pathways all play key roles in determining a therapeutic approach. This project is based on the study of topical minoxidil's effectiveness in treating ED. METHODS: To perform a comprehensive overview of the subject, we performed a triple-keyword combination search to assess recent studies of ED. RESULTS: The most common formulation used in these studies was 2% minoxidil solution. Except for cases studied in paralytic patients, topical treatment with minoxidil appears to elicit a mild erectile response; however, this finding is insufficient to confirm the effectiveness of this topical treatment. CONCLUSIONS: Although evidence to confirm the therapeutic properties of minoxidil in ED is limited, combination therapy and the use of modern formulations of minoxidil are promising options for treating ED in the future.

An overview of the history, current strategies, and potential future treatment approaches in erectile dysfunction: a comprehensive review.

INTRODUCTION: Erectile dysfunction (ED) is one of the most common urologic problems in men worldwide, with an approximately high incidence rate, significantly affecting patients' quality of life and their sexual partners. OBJECTIVES: Due to the association of this disorder with essential diseases such as cardiovascular disease and diabetes, its prevention and treatment are vital for overall human physiologic and psychological health. Along with reviewing the history of treatment and current methods, we seek new approaches to curb this issue in the future. METHODS: In this review, investigations were based on the focus of each section's content or conducted on an ad hoc basis. Searches were performed in Scopus and PubMed. RESULTS: In recent years, many treatments for ED have been reported besides oral administration of phosphodiesterase 5 inhibitors such as sildenafil and tadalafil (approved by the Food and Drug Administration). Common oral medications, intracavernous injections, herbal therapies (eg, herbal phosphodiesterase 5 inhibitors), and topical/transdermal medications are routine ED treatment approaches. Moreover, some novel medications are innovative candidates for completing ED's treatment protocols: stem cell injection, low-intensity extracorporeal shock wave therapy, platelet-rich plasma injection, gene therapy, amniotic fluid matrices, rho-kinase inhibitors, melanocortin receptor antagonists, maxi-K channel activators (ie, large-conductance calcium-activated potassium channels), guanylate cyclase activators, and nitric oxide donors. CONCLUSION: Due to the importance of this complicated problem in men's society, a faster course of treatment trends toward new methods is needed to increase efficiency. Combining the mentioned treatments and attentively examining their efficacy through programmed clinical trials can be a big step toward solving this global problem.

Prostaglandins as a Topical Therapy for Erectile Dysfunction: A Comprehensive Review.

INTRODUCTION: Erectile dysfunction (ED) is a substantial cause of dissatisfaction among many men. This discontentment has led to the emergence of various drug treatment options for this problem. OBJECTIVES: Unfortunately, due to various interactions, contraindications, and side effects, systemic therapies such as phosphodiesterase-5 inhibitors (including sildenafil, tadalafil, vardenafil, avanafil, etc.) are not welcomed in many patients. These problems have led researchers to look for other ways to reduce these complications. METHODS: This article holistically reviews the efficacy of topical prostaglandins and their role in treating ED. We sought to provide a comprehensive overview of recent findings on the current topic by using the extensive literature search to identify the latest scientific reports on the topic. RESULTS: In this regard, topical and transdermal treatments can be suitable alternatives. In diverse studies, prostaglandins, remarkably PGE1 (also known as alprostadil), have been suggested to be an acceptable candidate for topical treatment. CONCLUSION: Numerous formulations of PGE1 have been used to treat patients so far. Still, in general, with the evolution of classical formulation methods toward modern techniques (such as using nanocarriers and skin permeability enhancers), the probability of treatment success also increases.
