Background: Erectile dysfunction (ED) is a significant health issue affecting the global male population, with a complex and multifaceted etiology. High-fat diet (HFD) is known to impair endothelial function and promote the development of ED. Hinokiflavone (HINO), a naturally occurring biflavonoid, has garnered attention for its notable antioxidant and anti-inflammatory activities, suggesting its potential therapeutic role in treating ED.

Aim: We sought to investigate the effects of PA on endothelial cells, with an emphasis on ferroptosis.
Brain volume decrease in the anterior cingulate cortex (ACC) after lead (Pb) exposure has been linked to persistent impairment of attention behavior. However, the precise structural change and molecular mechanism for the Pb-induced ACC alteration and its contribution to inattention have yet to be fully characterized. The present study determined the role of miRNA regulated synaptic structural and functional impairment in the ACC and its relationship to attention deficit disorder in Pb exposed mice.

Saturated free fatty acids are known to reduce NO production and then induce endothelial dysfunction. Alternative splicing participates in the regulation of cellular and tissular homeostasis and is highly regulated by serine-arginine protein kinase (SRPK1).

Background: Extracellular vesicles (EVs) contain thousands of proteins and nucleic acids, playing an important role in cell-cell communications. Sertoli cells have been essential in the testis as a "nurse cell". However, EVs derived from human Sertoli cells (HSerCs) have not been well investigated.
View Article and Find Full Text PDFTesticular endothelial cells have been found to play an important role in spermatogenesis and fertility, but their mechanism is obscure. Exosomes released by various cells are recognized as cell-cell communication mediators during the initiation and progression of many diseases. Therefore, the current study aimed to investigate the protein and miRNA components of human testicular endothelial cell-derived exosomes (HTEC-Exos) and to explore their potential effects on spermatogenesis.

However, few isolation methods can achieve high purity and yield simultaneously. Therefore, we developed a novel and cost-effective procedure to separate BM-EVs "salting-out.

Methods: A multicenter, randomized, double-blind, placebo-controlled, double-cycle crossover trial was conducted in three medical centers. Male patients with mild to moderate ED were randomized into two groups and received either aildenafil citrate or placebos, followed by a crossover administration after a 7-day washout.
Background: Icariside II (ICA II), an active flavonoid monomer, has been proven to restore post-prostatectomy erectile dysfunction in rats; however, the high cost of extraction from natural plants limits the application of ICA II.
Objective: To investigate the therapeutic effect and possible mechanism of action of YS-10, a new flavonoid compound, which was designed and synthesized based on the structure of ICA II in a rat model in of cavernous nerve injury.
Materials/methods: Eight of 32 adult male Sprague-Dawley rats were selected as the normal control (NC) group and received vehicle treatment.
This study aimed to compare the effects of bilateral cavernous nerve crushing (BCNC) and bilateral cavernous nerve resection (BCNR) on intracavernous pressure (ICP) and cavernous pathology in rats and to explore the optimal treatment time for the BCNC and BCNR models. Seventy-two male rats aged 12 weeks were randomly divided into three equal groups: Sham (both cavernous nerves exposed only), BCNC (BCN crushed for 2 min), and BCNR (5 mm of BCN resected). Erectile function was then measured at 1 week, 3 weeks, and 5 weeks after nerve injury, and penile tissues were harvested for histological and molecular analyses by immunohistochemistry, immunofluorescence, Western blot, and cytokine array.

Fifty-six 8-week-old Sprague-Dawley rats received intraperitoneal injection of STZ (60 mg kg-1 ), and 8 weeks later, the determined diabetic rats randomly received intracavernous (IC) injection of phosphate buffer solution (PBS), ADSCs, or MTs. Another eight normal rats equally got IC injection of PBS.
View Article and Find Full Text PDFLead (Pb) is an environmental neurotoxic metal. Pb exposure may cause neurobehavioral changes, such as learning and memory impairment, and adolescence violence among children. Previous animal models have largely focused on the effects of Pb exposure during early development (from gestation to lactation period) on neurobehavior.

On the other hand, derivation of NK-like cells from more abundant cell sources such as embryonic stem cells (ESCs) and umbilical cord blood (UCB) requires the selection of rare CD34+ cells. Thus, we sought to convert adipose-derived stem cells (ADSCs), which are abundant and natively CD34+, into NK-like cells.

SD rats (n = 75) were randomly divided into 5 groups (normal control, diabetic control, 3 different dose LESWT treated diabetic groups). Diabetic rats were induced by intra-peritoneal injection of STZ (60 mg/kg) and rats with fasting blood glucose ≥ 300 mg/dL were selected as diabetic models.
