Bladder outlet obstruction (BOO) is common in males with benign prostate enlargement (BPE) and often presents with different lower urinary tract symptoms. Overactive bladder (OAB) has been reported to be related to BOO, although it can also be idiopathic. The storage symptoms of BOO are often similar to those of OAB.

The research findings show: (1) The main factors influencing the deformation of the diversion tunnel's surrounding rock are the high ground stress environment, the degree of fracture development in the rock mass, and the effectiveness of the support system. (2) Following the excavation of the first layer, extensive shallow damage predominates, with damaged blocks primarily exhibiting sheet-like and plate-like forms.

Methods: A total of 32 treatment plans for 22 patients were collected, whose planning CT and the centroid position of the planning target volume (PTV) were used as the reference. Images of different respiratory phases in 4DCT were acquired to redefine the targets and obtain the floating PTV centroid positions.
Patients with end stage renal disease (ESRD) are at high risk of developing upper tract urothelial carcinoma (UTUC). Due to high recurrence rate of UTUC in contralateral kidney and ureter, and high risk of complications related to surgery and anesthesia, whether it's necessary to remove both kineys and ureters at one time remains in debate. We utilized Taiwanese UTUC Registry Database to valuate the difference of oncological outcomes and perioperative complications between patients with ESRD with unilateral and bilateral UTUC receiving surgical resection.

However, many pregnant women have concerns regarding vaccination in terms of safety for themselves and their neonates. Therefore, we studied the obstetric outcomes of pregnant women in Zunyi, China.

We investigated, for the first time, whether MMF attenuates lung IR injury through inhibition of the GAPDH/Siah1 signaling pathway. Rats were subjected to IR injury using an isolated perfused lung model, and proximity ligation assays were employed to evaluate the presence and distribution of the GAPDH/Siah1 complex.

The iridoids is one of the main constituents of many heat-clearing and detoxifying Chinese medicines that were largely planted and frequently used in clinical practice. Twenty-three representative high content iridoids from several staple Chinese medicines were obtained and tested by a SARS-CoV-2 pseudo-virus entry-inhibition assay on HEK-293 T/ACE2 cells, a live HCoV-OC43 virus infection assay on HRT-18 cells, and a SARS-CoV-2 3CL protease inhibitory FRET assay followed by molecular docking simulation.

Materials And Methods: A total of 2114 patients were included from the updated data of the Taiwan UTUC Collaboration Group. It was divided into two groups: IVR-free and IVR after RNUx, with 1527 and 587 patients, respectively.

Objective: Evidence suggests that aldehyde dehydrogenase 2 (ALDH2) offers protection against damage caused by oxidative stress in diverse rodent models. Nonetheless, the effect of Alda-1, a compound that activates ALDH2, on acute lung injury (ALI) induced by air embolism (AE) remains unclear. The objective of this study was to explore the protective effects of Alda-1 in ALI induced by AE.

Materials And Methods: From October 2020 to September 2021, a retrospective analysis of patients' medical records was performed. Records of past history, physical examination, laboratory tests, and imaging investigations were reviewed.
Background: Ectopic kidney and median arcuate ligament syndrome are both rare conditions. The clinical presentation and diagnosis of these conditions are not well studied. There are no reports on the combination of these two rare conditions.

Micro/Nano-scale particles are widely used as vaccine adjuvants to enhance immune response and improve antigen stability. While aluminum salt is one of the most common adjuvants approved for human use, its immunostimulatory capacity is suboptimal. In this study, we modified risedronate, an immunostimulant and anti-osteoporotic drug, to create zinc salt particle-based risedronate (Zn-RS), also termed particulate risedronate.

In the last two decades, the proportion of HNCs attributable to HPV infection has increased worldwide, notably the oropharyngeal cancers. However, the trend of HPV-related HNC burden is not clearly understood yet in China.

However, the pathophysiological role of intrinsic circadian clocks Rev-Erbα in ischemia-reperfusion (IR)-induced acute lung injury (ALI) remains unclear.
Methods: The IR-ALI model was established by subjecting isolated perfused rat lungs to 40 min of ischemia followed by 60 min of reperfusion.
Neuromorphic computing aims to emulate the computing processes of the brain by replicating the functions of biological neural networks using electronic counterparts. One promising approach is dendritic computing, which takes inspiration from the multi-dendritic branch structure of neurons to enhance the processing capability of artificial neural networks. While there has been a recent surge of interest in implementing dendritic computing using emerging devices, achieving artificial dendrites with throughputs and energy efficiency comparable to those of the human brain has proven challenging.

Male FVB mice were exposed to retired male C57BL/6 mice for 60 min daily over a 4-week period. In the third week, these FVB mice received intraperitoneal injections of either saline (SSS group) or ketamine (SSK group).

Methods: This study is a multi-institutional retrospective analysis of patients with high-risk upper tract urothelial cancer who underwent neoadjuvant chemotherapy and radical nephroureterectomy between 2002 and 2021. Logistic regression analyses were used to investigate all clinical parameters for response after neoadjuvant chemotherapy.
