Long-Term Prostate-Specific Antigen Response on a Low-Dose Cabazitaxel Regimen for Metastatic Castration-Resistant Prostate Cancer: A Case Report.

BACKGROUND Cabazitaxel is a second-generation taxane approved for patients with metastatic castration-resistant prostate cancer (CRPC). Although cabazitaxel improves overall survival when used following docetaxel chemotherapy, duration of the clinical response is relatively short, and few patients achieve a long-term response. CASE REPORT A 71-year-old man with prostate adenocarcinoma with an initial prostate-specific antigen (PSA) level of 4956 ng/ml, Gleason score 4+5 and cTxN0M1b was referred to our department for treatment.

Metabotropic Glutamate Receptor Subtype 7 Is Essential for Ejaculation.

Metabotropic glutamate receptor subtype 7 (mGluR7) is a member of the group III mGluRs, which are negatively coupled to adenylate cyclase via Gi/Go proteins and localized to presynaptic active zones of the mammalian central nervous system (CNS). To elucidate the mechanism of impaired reproductivity of mGluR7 knockout (KO) mice, we investigated sexual behavior in this line, which exhibits ejaculatory disorder, although with normal sexual motivation and erectile function. To identify the site of action within the CNS responsible for the effect of mGluR7 on ejaculation, we then used a para-chloroamphetamine (PCA)-induced ejaculation model.

Off-clamp tumor excision using soft coagulation in laparoscopic and robotic partial nephrectomy.

Introduction: The aim of this study was to assess the perioperative outcomes of off-clamp tumor excision using soft coagulation in laparoscopic and robotic partial nephrectomy.

Methods: We retrospectively analyzed the data from 78 patients who underwent minimally invasive partial nephrectomy, using soft coagulation, at the Shiga University of Medical Science, between September 2013 and April 2017. Tumor excision and hemostasis without renal arterial clamping was performed using soft coagulation.

Generation of an OCT3/4 reporter cynomolgus monkey ES cell line using CRISPR/Cas9.

Cynomolgus monkey ES (Cyn ES) cells can be generated in a similar manner as human ES cells. However, Cyn ES cells are difficult to maintain in an undifferentiated state by untrained researchers. For easier culture, we generated an OCT3/4-P2A tdTomato IRES Zeocin Cyn ES cell line using CRISPR/Cas9 genome editing technology.

Changes in renal function following nedaplatin-containing chemotherapy in patients with urothelial carcinoma unfit for cisplatin.

The present study evaluated the impact of nedaplatin-containing chemotherapy on renal function in 35 patients with urothelial carcinoma (UC) between 2001 and 2014 who were unfit for cisplatin treatment. As comparative controls, the present study also examined 35 patients with the same disease who underwent cisplatin-containing chemotherapy during the same period. The changes in the estimated glomerular filtration rate (eGFR) prior to and following the administration of nedaplatin during each cycle of chemotherapy was investigated.

Exploratory Investigation of Target Pazopanib Concentration Range for Patients With Renal Cell Carcinoma.

Background: Severe adverse events frequently occur in patients treated with pazopanib, necessitating dose reduction and discontinuation. However, information on the exposure-toxicity relationship is limited.

Patients And Methods: For this retrospective and observational clinical study, we examined 27 patients with renal cell carcinoma treated with pazopanib and enrolled between October 2014 and March 2018.

Prediction of intravesical recurrence of non-muscle-invasive bladder cancer by evaluation of intratumoral Foxp3+ T cells in the primary transurethral resection of bladder tumor specimens.

Patients with a history of non-muscle-invasive bladder cancer sometimes have recurrence of tumors after transurethral resection of bladder tumor treatment. To find factors related to the recurrence of non-muscle-invasive bladder cancer, we examined tissue specimens taken at transurethral resection of bladder tumor as an initial treatment. We revealed the association between prognosis of non-muscle-invasive bladder cancer and infiltration of Foxp3+ T cells that suppress anti-tumor immunity in 115 primary non-muscle-invasive bladder cancer patients retrospectively identified and followed for at least 3 months after primary transurethral resection.

The location of the bladder neck in postoperative cystography predicts continence convalescence after radical prostatectomy.

Background: This study was conducted to determine whether the location of the bladder neck in postoperative cystography predicts recovery of continence after radical prostatectomy.

Methods: Between 2008 and 2015, 203 patients who underwent laparoscopic radical prostatectomy (LRP, n = 99) and robot assisted radical prostatectomy (RARP, n = 104) were analyzed. The location of the bladder neck was visualized by postoperative routine cystography, and quantitative evaluation of the bladder neck position was performed according to the bladder neck to pubic symphysis (BNPS) ratio proposed by Olgin et al.

Evaluation of hydronephrosis with tubeless cutaneous ureterostomy using Tc-99m MAG3 diuretic renography.

Purpose: To assess hydronephrosis of tubeless cutaneous ureterostomy using Tc-99m mercaptoacetyltriglycine (MAG3) diuretic renogram.

Materials And Methods: Cutaneous ureterostomy with a unilateral stomal creation was performed in 15 patients (27 renal units) with a minimum follow-up period of 6 months. Stomal obstruction was evaluated with Tc-99m MAG3 diuretic renography 3 months after the surgery.

[Clinical study of tubeless cutaneous ureterostomy].

We constructed Toyoda cutaneous ureterostomy with fixation between the anterior and posterior rectus sheath by four interrupted sutures to maintain the stability of the abdominal wall tunnel for the ureters. After the operation, the stent catheters were placed in the renal pelvis through the stoma, and exchanged every 4 weeks. The stent catheters were removed 3 months after the operation, because the stomal conditions were unstable and obstructive in the early phase after the operation.

Promoter of Arabidopsis thaliana phosphate transporter gene drives root-specific expression of transgene in rice.

The PHT1 promoter::GUS fusion gene was constructed and introduced into Arabidopsis and rice by Agrobacterium-mediated transformation. Strong beta-glucuronidase (GUS) activity was detected in roots and showed phosphate starvation induction both in Arabidopsis and rice. In contrast, GUS activity in aerial tissues such as those of the leaf and stem was low.
