Galectin-3 (Gal-3) is a multifunctional protein that has been linked to fibrosis and inflammation in the cardiovascular system. In this study, we examined the impact of Gal-3 on inflammation and fibrosis in patients with arteriogenic erectile dysfunction (A-ED) and the underlying mechanisms involved. To induce arterial injury, we utilized cuffs on the periaqueductal common iliac arteries of Sprague‒Dawley (SD) rats and administered a high-fat diet to co-induce local atherosclerosis.

Objective: To investigate the application value of RigiScan monitoring in assisting tadalafil medication.

Methods: This self-control study included 89 ED patients (IIEF-5 < 21) treated in our hospital from August 2019 to July 2020. The patients underwent audiovisual sexual stimulation (AVSS), nocturnal penile tumescence and rigidity (NPTR) test, scoring on the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder 7-Item Scale (GAD-7), blood routine test, blood biochemical analysis, and hormone secretion examination, which confirmed 21 cases of psychogenic, 28 cases of organic and 40 cases of mixed ED.

Mesenchymal stem cells (MSCs) are viewed as an increasingly promising treatment for age-related erectile dysfunction (AED). Owing to the limitations of injecting living cells, the injection of exosomes appears to be a more plausible option. However, whether MSC-derived exosomes (MSC-Exos) improve AED and their potential mechanism remains unknown.

Cholangiocarcinoma (CCA) is a common and lethal malignant tumor originating from bile duct epithelial cells. Various tumor biomarkers have been used for its clinical screening, such as carbohydrate antigen 19-9 and carcinoembryonic antigen. This study aimed to demonstrate the value of associated genes-CMT1A duplicated region transcript 15 (CDRT15) for prognosis of CCA by integrated bioinformatics analysis.

Radical pelvic surgery is commonly accompanied by the risk of postoperative erectile dysfunction induced by cavernous nerve injury (CNI-ED). The strategy of using adipose mesenchymal stem cell-derived exosomes (ADSC-Exo) to treat neurodegenerative diseases has shown promising results. However, it remains challenging to prolong the retention of unbound ADSC-Exo in damaged tissues to exert therapeutic effects.

Introduction: Non-ketotic hyperglycaemic hemichorea-hemiballismus (NHHH) is often secondary to middle-aged and elderly diabetic people with poor-controlled diabetes; Fahr's disease (FD) is another rare neurological disorder characterized by abnormal calcified deposits in the brain that control movement. We described a rare case of NHHH combined with a heterozygous mutation (SLC20A2) resulting in one family with FD.

Case Presentation: The patient has a 30-day history of involuntary choreic movements of the left limbs and left face.

Nitric oxide synthase- (NOS-) dependent endothelial dysfunction induced by oxidative stress (OS) is assumed to play a pivotal role in the pathogenesis and progression of diabetes mellitus-related erectile dysfunction (DMED). Cysteine-rich whey protein isolate (CR-WPI) is a widely used protein supplement and has been confirmed to reduce reactive oxygen species (ROS) by increasing cellular antioxidant glutathione (GSH). However, it is currently unknown whether CR-WPI elicits therapeutic effects in DMED.

The pharate larval stage of Paraleuctra tianmushana Li & Yang is described for the first time. The yellowish-brown larvae of this species are characterized by a slender abdomen lacking setae and a unique pattern of dark pigmentation on the head, pronotum, and abdominal terga. Additionally, vestigial cervical gills in this species are present, a character not present in known Nearctic species.
