This study evaluated the impact of aspirin on biochemical recurrence (BCR) rate following robot-assisted radical prostatectomy (RARP) in patients. A database search identified patients who underwent RARP for pT2-3N0M0 disease at any 25 centers between 2011 and 2022, categorized into (n = 350) control groups 5857). Adjustment by 1:1 propensity score matching (PSM) Mahalanobis distance (MDM) created 350 matched pairs. The effect BCR was analysis BCR-free survival. After PSM MDM, 3-year...

ABSTRACT Background High‐risk patients with prostate cancer (PC) frequently experience biochemical recurrence (BCR) after surgery. Thus numerous studies have investigated the efficacy of neoadjuvant therapies for high‐risk PC patients; however, no protocol has been established. This study aimed to assess effect androgen deprivation therapy combined low‐dose estramustine phosphate (EMP) on BCR compared (ADT) alone in high‐ and very PC. Methods retrospective targeted meeting National...

Abstract This study aimed to assess the effects of thienopyridine-class antiplatelet agents (including ticlopidine, clopidogrel, and prasugrel) on bleeding complications in patients who underwent robot-assisted radical prostatectomy. cohort used a database for prostatectomy at 23 tertiary centers nationwide between 2011 2022. Patients received thienopyridines (thienopyridine group) were compared with those aspirin monotherapy (aspirin group). The primary outcome was incidence complications....

Scope Dietary deprivation of essential amino acids (EAAs) in mammals is known to cause reductions food intake and body weight. The aim this study was determine whether how mice respond individual EAA species. Methods results any single (not non-EAA) led progressive weight loss the order Ile− > Val− Thr− Leu− Trp− His− Phe− Met− Lys−, which correlated with reduction intake. Decreased levels deprived EAAs as well increased all or some other were detected serum, although these differed among...

The molecular mechanism of insulin resistance induced by high-fructose feeding is not fully understood. present study investigated the role downstream signaling molecules phosphatidylinositol 3-kinase (PI3K) in insulin-stimulated skeletal muscle high-fructose-fed rats. Rats were divided into chow-fed and fructose-fed groups. results euglycemic clamp (insulin infusion rates: 6 mU/kg BW/min) showed a significant decrease glucose rate (GIR) metabolic clearance (MCR) rats compared with In...

Treatment of 3T3-L1 adipocytes with insulin resulted in activation 2-deoxyglucose transport activity and translocation glucose transporters (GLUT4 GLUT1) from the cytoplasmic space to plasma membrane. ML-9 (a myosin light chain kinase inhibitor) inhibited stimulation by 80% at 100 microM (IC50 = 27 microM) without affecting basal state. The inhibition was independent extracellular Ca2+ concentration almost fully reversible 40 ML-9. did not inhibit insulin-stimulated tyrosine phosphorylation...

We investigated whether phosphatidylinositol 3-kinase (PI3K) is phosphorylated and its specific activity increased by insulin stimulation in vivo using Fao cells antibodies raised against the 85 kDa subunit of PI3K, insulin-receptor substrate-1 (IRS-1), phosphotyrosine (pTyr). PI3K was detected immunoprecipitate produced with anti-PI3K at a basal state. The 2-3-fold stimulation, although protein concentration kinase immunoprecipitates same before after stimulation. Both anti-pTyr anti-IRS-1...

The kidney is one of the major loci for expression cystathionine β-synthase (CBS) and γ-lyase (CTH). While CBS-deficient (Cbs(-/-)) mice display homocysteinemia/methioninemia severe growth retardation, rarely survive beyond first 4 wk, CTH-deficient (Cth(-/-)) show homocysteinemia/cystathioninemia but develop with no apparent abnormality. This study examined renal amino acid reabsorption in those mice. Although both 2-wk-old Cbs(-/-) Cth(-/-) had normal architecture, their serum/urinary...
