Characteristics of inappropriate multiple medication use in older urological outpatients.

Objectives: To investigate polypharmacy and potentially inappropriate medications (PIMs) in elderly patients visiting the urology department for lower urinary tract symptoms (LUTS).

Methods: We retrospectively analyzed digital medical records of individuals over the age of 65 who visited the urology department for LUTS. This cross-sectional study was conducted in 10 hospitals located in South Korea, between September 2017 and December 2017.

Prognostic value of preoperative systemic inflammation markers in localized upper tract urothelial cell carcinoma: a large, multicenter cohort analysis.

Background: The aim of this study was to investigate the prognostic value of preoperative systemic inflammation markers in upper tract urothelial carcinoma (UTUC).

Methods: A total of 1137 patients who underwent radical nephroureterectomy with bladder cuff excision at 9 institutions from 2004 to 2015, were retrospectively reviewed. The Glasgow Prognostic Score (GPS), modified GPS (mGPS), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) for each patient were calculated.

Mild hypothermia protects obese rats from fulminant hepatic necrosis induced by ischemia-reperfusion.

Background: Obese Zucker rats demonstrate increased susceptibility to hepatic ischemia-reperfusion injury. This study evaluates the effect of mild systemic hypothermia on ischemia-induced acute fulminant necrosis during warm ischemia and reperfusion, and investigates blood metabolic profiles under normothermic and mildly hypothermic conditions.

Methods: The left and median hepatic lobes of male, obese, Zucker rats were exposed to 75 minutes of ischemia under either normothermic (36.

Warm ischemia-induced alterations in oxidative and inflammatory proteins in hepatic Kupffer cells in rats.

The aim of the study was to investigate the impact of ischemia/reperfusion injury on the proteome of Kupffer cells. Lean Zucker rats (n = 6 each group) were randomized to 75 min of warm ischemia or sham operation. After reperfusion for 8 h, Kupffer cells were isolated by enzymatic perfusion and density gradient centrifugation.

Glutamine does not protect against hepatic warm ischemia/reperfusion injury in rats.

The administration of glutamine before experimental ischemia/reperfusion (I/R) has been shown to protect intestinal, pulmonary, and myocardial tissue by inducing heat shock proteins (HSP). However, it is not known whether glutamine is protective for all organs. We therefore tested whether pretreatment with glutamine reduces injury following hepatic I/R in rats.

Mild hypothermia provides significant protection against ischemia/reperfusion injury in livers of obese and lean rats.

Objective: To evaluate the effect of anesthesia induced mild systemic hypothermia on hepatic injury in lean and obese rats during warm ischemia.

Summary Background Data: Hepatic warm ischemia during surgery remains a significant problem, particularly in organs with presumed baseline dysfunction.

Methods: The left and median lobes of male lean and obese Zucker rats were exposed to 75 minutes of ischemia under either mild hypothermic or normothermic conditions.

Benzo(a)pyrene-induced apoptotic death of mouse hepatoma Hepa1c1c7 cells via activation of intrinsic caspase cascade and mitochondrial dysfunction.

Benzo(a)pyrene (BaP), a potent carcinogen, has been shown to induce apoptosis via activation of caspase-3. However, the upstream of caspase-3 and other apoptosis signaling remain to be elusive. Herein, we demonstrated that treatment of Hepa1c1c7 cells with BaP increased the transcriptional expression of aryl hydrocarbon nuclear transporter and cytochrome p450 1A1 in a time and dose-dependent manner but did not aromatic hydrocarbon receptor.
