Background: Trehalose-6-phosphate synthase (HcTPS) and trehalose-6-phosphate phosphatase (HcGOB) are key enzymes for trehalose synthesis in Haemonchus contortus. In addition, previous studies have also demonstrated that HcTPS and HcGOB can regulate the function of host immune cells in vitro, and are important immunosuppressive molecules. Therefore, this study evaluated the potential of HcTPS and HcGOB as vaccine candidates through in vitro and in vivo experiments.

However, the expression of a key neurotrophic factor, brain-derived neurotrophic factor (BDNF), was low in both MSCs and MSC microspheres, restricting the associated neural repair. Based on the hypoxia and oxidative stress microenvironments within cell spheroids and lesion areas, BDNF-expressing nanocomplexes that are dual-responsive to hypoxia and reactive oxygen species were designed to modify MSCs, achieving high BDNF expression in MSC spheroids.

The development of novel antimicrobial coatings is needed to prolong the service life of catheters and reduce the incidence of CAUTIs. Herein, we designed an antimicrobial catheter coated with a piezoelectric zinc oxide nanoparticles (ZnO NPs)-incorporated polyvinylidene difluoride-hexafluoropropylene (ZnO-PVDF-HFP) membrane.

Case Presentation: In this case report, we introduced a patient who was diagnosed with LPS in the scrotum. In his right scrotum, we found a large soft tissue mass, including fat and calcification.
Phosphodiesterase type 5 inhibitors (PDE5is) constitute the primary therapeutic option for treating erectile dysfunction (ED). Nevertheless, a substantial proportion of patients, approximately 30%, do not respond to PDE5i treatment. Therefore, new treatment methods are needed.

The experimental groups and operational details are as follows: A total of thirty-two SD rats were divided into four groups: the DN model group (DN, = 8), DN + In treatment group (DN + In, = 8), DN + In + UA administration group (DN + In + UA, = 8), and negative control group (control, = 8). After 8 weeks, changes in renal function indices and pathological damage were assessed.

Methods: Eighteen 10-week-old male Sprague-Dawley (SD) rats were randomly divided into 3 groups. Six rats were used as the control group (Control), and the remaining 12 were given a single X-ray irradiation of 20 Gy in the prostate and then randomly divided into the radiation injury group (Ri-ED group) and YS-10 treatment group (Ri-ED+YS-10, 2.
Objective: To explore the preventive and therapeutic effects of Icariside Ⅱ (ICAⅡ) on radiation injury-induced ED (Ri-ED) in rats.
Methods: Twenty-four 10-week-old male SD rats received exposure of the prostate to single X-ray irradiation of 20 Gy, and were randomly equally divided into an Ri-ED group (6 survived and 6 died) and a treatment group treated with ICAⅡ at 4.5 mg/kg/d (9 survived and 3 died).
Objective: To investigate the effect and safety of low-intensity pulsed ultrasound (LIPUS) versus low-energy shock wave (LESW) in the treatment of neurogenic penile ED in male SD rats.
Methods: Twenty-four 12-week-old male SD rats were randomly divided into four groups of an equal number: sham operation, bilateral cavernous nerves injury (BCNI), LIPUS (300 mW /cm2, 3 times a week for 2 weeks), and LESW (300 strokes once, 3 times a week for 2 weeks). At 28 days after intervention, the erectile function of the rats was assessed by comparing the ratio of maximum intracavernous pressure to mean arterial pressure (ICPmax/MAP), and the histopathological changes in the corpus cavernosum of the penis were observed by immunohistochemistry, immunofluorescence staining, and Masson trichromatic staining.
Bovine milk-derived extracellular vesicles (BM-EVs) are recognized as promising nanoscale delivery vectors owing to their large availability. 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.

In this study, the enzyme degradation of Hericium erinaceus polysaccharide (HEP) was successfully modified with endo-rhamnosidase to obtain the enzymatic hydrolysis of Hericium erinaceus polysaccharide product (EHEP). The gas chromatography-mass spectrometry (GC-MS), high performance gel permeation chromatography (HPGPC), Fourier transformed infrared spectrometry (FT-IR), scanning electron microscopy (SEM), atomic particle microscopy (AFM), nuclear magnetic resonance (NMR) and particle size distribution were used to characterize polysaccharides. In vitro, EHEP significantly enhanced the phagocytosis, NO, CD40 and CD86 by macrophage than HEP.

However, due to the sponge-like structure of corpus cavernosum (CC) with abundant vessels, ICI was indeed like intravenous injection. Thus, the cell escaping may be a concern of safety and limited therapy, but the issue has not been clearly demonstrated yet.

Methods: Fifty Sprague-Dawley rats underwent vaginal distension and bilateral ovariectomy mimicking partum injury and menopause to construct SUI models, which were further randomized into 100 mW/cm LIPUS, 200 mW/cm LIPUS, 300 mW/cm LIPUS, and none-treatment control subgroups with 10 rats per subgroup. Ten rats served as mock operation control.
Smooth muscle differentiated human adipose derived stem cells (hADSCs) provide a crucial stem cell source for urinary tissue engineering, but the induction of hADSCs for smooth muscle differentiation still has several issues to overcome, including a relatively long induction time and equipment dependence, which limits access to abundant stem cells within a short period of time for further application. Three-dimensional (3D) bioprinting holds great promise in regenerative medicine due to its controllable construction of a designed 3D structure. When evenly mixed with bioink, stem cells can be spatially distributed within a bioprinted 3D structure, thus avoiding drawbacks such as, stem cell detachment in a conventional cell-scaffold strategy.
