Low-intensity extracorporeal shock wave therapy (Li-ESWT) is used in the treatment of erectile dysfunction, but its mechanisms are not well understood. Previously, we found that Li-ESWT increased expression brain-derived neurotrophic factor (BDNF). Here assessed underlying signaling pathways Schwann cells vitro and penis tissue vivo after nerve injury. The result indicated BDNF were significantly by injury, as (SCs, RT4-D6P2T) vitro. activated protein kinase RNA-like endoplasmic reticulum...

Abstract Erectile dysfunction (ED) is a major health issue among men with diabetes, and ED induced by diabetes mellitus (DMED) particularly difficult to treat. Therefore, novel therapeutic approaches for the treatment of DMED are urgently needed. Exosomes, nanosized particles involved in many physiological pathological processes, may become promising tool treatment. In this study, we investigated effect exosomes derived from corpus cavernosum smooth muscle cells (CCSMC‐EXOs) on erectile...

Aim Stress urinary incontinence (SUI) is a significant health problem for women. Treatments employing muscle derived stem cells (MDSCs) may be promising approach to this prevalent, bothersome condition, but these treatments are invasive and require collection of from one site injection into another. It also unknown whether or not establish themselves function as in the target tissues. Alternatively, low‐intensity extracorporeal shock wave therapy (Li‐ESWT) non‐invasive has shown positive...

Midbrain astrocyte-derived neurotrophic factor (MANF) is a secreted protein induced by endoplasmic reticulum stress. Previous studies have indicated that intravenous administration of 1 mg/kg/day recombinant human MANF with His tag (His-MANF) for 3 days can ameliorate acute ulcerative colitis in mice. However, long-term therapy has many disadvantages. In this paper, His-MANF was successfully encapsulated into alginate and hyaluronic acid hybrid hydrogel microcapsules one step using the gas...
