Background/Objectives: Modern societal stressors have been linked to declining testosterone levels among young men, contributing somatic, psychological, and sexual health problems. Despite growing evidence suggesting a link between trace elements testosterone-related symptoms, there are only few comprehensive analyses on younger populations. This study's aim was examine how serum modulate the relationship symptom severity. Methods: cross-sectional study included 225 men seeking infertility...

Renal cell carcinoma (RCC) features altered lipid metabolism and accumulated polyunsaturated fatty acids (PUFAs). Elongation of very long-chain acid (ELOVL) family enzymes catalyze elongation, ELOVL5 is indispensable for PUFAs but its role in RCC progression remains unclear. Here, we show that higher levels correlate with poor clinical prognosis. Liquid chromatography/electrospray ionization-tandem mass spectrometry analysis showed decreases end products (arachidonic eicosapentaenoic acid)...

Renal cell carcinoma (RCC) is an aggressive genitourinary malignancy which has been associated with a poor prognosis, particularly in patients metastasis, its major subtypes being clear RCC (ccRCC), papillary PCC (pRCC) and chromophobe (chRCC). The presence of intracellular lipid droplets (LDs) considered to be hallmark ccRCC. importance altered metabolism ccRCC widely recognized. elongation very‑long‑chain fatty acid (ELOVL) catalyzes the acids (FAs), modulating composition, required for...

Methods SP/serum 20 TEs (lithium, sodium, magnesium, phosphorus, sulfur, potassium, calcium, manganese, iron, cobalt, copper, zinc, arsenic, selenium, rubidium, strontium, molybdenum, cesium, barium, and thallium) were calculated for healthy volunteers ( n = 4) those consulting subfertility 245). Volunteer semen samples collected by split...

To identify the prognosis of Japanese patients with collecting duct carcinoma (CDC). We used a hospital-based cancer registry data in Japan to extract CDC cases that were diagnosed 2013, histologically confirmed, and determined first course treatment. further investigated treatment modalities estimated overall survival (OS) by Kaplan–Meier method. A total 61 identified. The 5-year OS rate for all who during 2013 was 23.6% (95% CI: 15.0–37.4), median 14 months 12–24). at stages I, III, IV...

To clarify the long-term prognoses of elderly upper tract urothelial carcinoma (UTUC) patients after surgery. We used a hospital-based cancer registry data in Japan to extract with pT1-3N0M0 UTUC diagnosed 2009 who underwent surgery, and classified them by age group (≤ 64, 65–74, ≥ 75 years old). estimated 10-year overall survival (OS) Kaplan-Meier analysis. For estimation, we calculated net (NS) Pohar-Preme method using Japanese life tables. A total 1139 (564 renal pelvic [RPC] 575 ureteral...

<title>Abstract</title> Squalene, a natural triterpene with antioxidant, anti-inflammatory, and immunostimulatory properties, holds promise for cancer therapy. Here, we examined previously developed, diethylene glycol derivative of squalene (SQ-diEG) investigated its in vivo anti-carcinogenic effects bladder cancer. C57BL/6 mice were treated 0.025% N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN) to induce cancer, SQ-diEG or PBS (control) administered orally from Week 0. significantly reduced...

Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal that involves various organs, but has predilection for the urinary bladder in genitourinary tract. Given approximately half of all IMT cases have anaplastic lymphoma kinase (ALK) rearrangements, ALK inhibitor crizotinib suggested as promising treatment unresectable cases. No reports on neoadjuvant therapy locally advanced are available. We report case 17-year-old Japanese boy referred to our institution painful urination and...

Oncogenic FGFR3-TACC3 fusions and FGFR3 mutations are target candidates for small molecule inhibitors in bladder cancer (BC). Because TACC3 genes located very closely on chromosome 4p16.3, detection of the fusion by DNA-FISH (fluorescent situ hybridization) is not a feasible option. In this study, we developed novel RNA-FISH assay using branched DNA probe to detect formaldehyde-fixed paraffin-embedded (FFPE) human BC samples.The was validated mouse xenograft model with cell lines. Next,...

Therefore, in this phase II study, we evaluated the efficacy and safety nivolumab relapsed tumor.Seventeen adult patients (median age 34 years) with refractory primary tumor after second-line or higher chemotherapy were enrolled. Nivolumab was administered over 30 min at 240 mg/body every 2 weeks until disease progression intolerable adverse event...
