Background: Transrectal ultrasound-guided prostate biopsy (TRUSPB) is widely used to diagnose prostate cancer (PCa). The aim of this study was to evaluate the risk of multi-factorial complications (febrile genitourinary tract infection (GUTI), rectal bleeding, and urinary retention) after TRUSPB.
Methods: N = 2053 patients were Japanese patients undergoing transrectal or transperineal TRUSPB for suspicious of PCa.
Objective: Older individuals often have multiple etiologies for their lower urinary tract symptoms (LUTS); i.e., both urologic (U) and neurologic (N) etiologies.

Case Presentation: Case 1, a 35-year-old nulliparous woman, and case 2, a 47-year-old nulliparous woman, had transient urinary retention. A urodynamics revealed increased bladder sensation in case 1 and detrusor underactivity with a large post-void residual in cases 1 and 2.

(Objective)Retroperitoneal fibrosis is largely divided into the idiopathic and secondary types. Some idiopathic cases include IgG4-related diseases, which are often similar to malignant diseases, such as lymphoma and sarcoma. The diagnostic criteria for IgG4-related disease are used and pathologic examination is necessary for a definitive diagnosis of IgG4-related retroperitoneal fibrosis.

Objectives: The present study aimed to identify clinical predictors associated with the risk of bladder cancer with LVI before a first TURBT.
Methods: A total of 291 patients underwent a first TURBT for bladder cancer at Toho University Sakura Medical Center between January 2012 and December 2016.
Histone H3 lysine 9 (H3K9) methylation is dynamically regulated by methyltransferases and demethylases. In spermatogenesis, prospermatogonia differentiate into differentiating or undifferentiated spermatogonia after birth. However, the epigenetic regulation of prospermatogonia to spermatogonia transition is largely unknown.

His sacral autonomic disorder was urinary retention without marked prostate hyperplasia. Urodynamics-sphincter electromyography revealed detrusor hyperactivity with impaired contraction and neurogenic changes of the sphincter motor unit potentials.

Objective: We aimed to correlate pressure-flow urodynamic parameters with video-gait analysis parameters in MSA.
Methods: We recruited 34 patients with MSA: 20 men, 14 women; age 64.
Background: The aim of this study was to identify the clinical predictors related to the risk of high-grade papillary bladder cancer before first-time transurethral resection of a bladder tumor (TUR-Bt), and to develop and validate a nomogram predicting the risk of high-grade papillary bladder cancer.
Methods: A retrospective clinical study of consecutive patients who underwent first-time TUR-Bt for papillary bladder cancer was performed. Medical records were reviewed uniformly, and the following data were collected: age, sex, episodes of urinary symptoms, tumor size, number of tumors, location of the largest tumor (lateral walls, base, posterior wall, dome, and anterior wall), tumor appearance (papillary or non-papillary, pedunculated or sessile), and urinary cytology.
The cellular prion protein, designated PrPC, is a membrane glycoprotein expressed abundantly in brains and to a lesser extent in other tissues. Conformational conversion of PrPC into the amyloidogenic isoform is a key pathogenic event in prion diseases. However, the physiological functions of PrPC remain largely unknown, particularly in non-neuronal tissues.

The c-index was 0.72 (95% confidence (CI): 0.

H3K9 demethylation is crucial in mouse sex determination; The H3K9 demethylase Jmjd1a deficiency leads to increased H3K9 methylation at the Sry locus in embryonic gonads, thereby compromising Sry expression and causing male-to-female sex reversal. We hypothesized that the H3K9 methylation level at the Sry locus is finely tuned by the balance in activities between the H3K9 demethylase Jmjd1a and an unidentified H3K9 methyltransferase to ensure correct Sry expression.
View Article and Find Full Text PDFPrion diseases are a group of fatal neurodegenerative disorders caused by prions, which consist mainly of the abnormally folded isoform of prion protein, PrPSc. A pivotal pathogenic event in prion disease is progressive accumulation of prions, or PrPSc, in brains through constitutive conformational conversion of the cellular prion protein, PrPC, into PrPSc. However, the cellular mechanism by which PrPSc is progressively accumulated in prion-infected neurons remains unknown.

Glomerular hyperfiltration peculiar to PA can mask mild renal failure before surgery. The aim of this retrospective study was to investigate postoperative renal functional outcomes in PA patients from different viewpoints and to develop novel nomograms that can predict renal functional outcomes in PA patients after surgery.

We previously reported transgenic mice expressing PrP with residues 25-50 deleted in the PrP-null background, designated as Tg(PrP∆preOR)/Prnp mice. Here, we produced two new lines of Tg(PrP∆preOR)/Prnp mice, each expressing the mutant protein, PrP∆preOR, 1.

Objective: Dutasteride is a 5-alpha reductase inhibitor used to treat benign prostatic hyperplasia. Dutasteride lowers prostate-specific antigen (PSA) levels, which may lead to delays in the diagnosis and treatment of prostate cancer (PCa). This study investigated patients who underwent prostate biopsy (PBx) while receiving dutasteride to investigate whether this agent affects the diagnosis and treatment of PCa.

Methods: A prospective study assessed the changes in arterial stiffness using the CAVI and clinical laboratory variables among 58 men with prostate cancer treated with ADT for 6 months. Furthermore, patients who had a high risk of developing arterial stiffness after ADT were investigated.
The aim of this study is to validate and compare the predictive accuracy of two nomograms predicting the probability of Gleason sum upgrading between biopsy and radical prostatectomy pathology among representative patients with prostate cancer. We previously developed a nomogram, as did Chun et al. In this validation study, patients originated from two centers: Toho University Sakura Medical Center (n = 214) and Chibaken Saiseikai Narashino Hospital (n = 216).

It has been shown that PrP-knockout (Prnp0/0) mice transgenically reconstituted with a mouse-hamster chimeric PrP lacking N-terminal residues 23-88, or Tg(MHM2Δ23-88)/Prnp 0/0 mice, neither developed the disease nor accumulated MHM2ScΔ23-88 in their brains after inoculation with RML prions. In contrast, RML-inoculated Tg(MHM2Δ23-88)/Prnp 0/+ mice developed the disease with abundant accumulation of MHM2ScΔ23-88 in their brains.
