Prostate Cancer: Under-representation of African American Men in Research Studies Used in the Latest NCCN Guidelines.

Objective: To evaluate racial data in studies used in current NCCN prostate cancer guidelines. These guidelines represent the latest information that informs clinical practice. Prostate cancer disproportionately affects mortality in Black patients compared to White patients at a 2.

Preventive effect of specific antioxidant on oxidative renal cell injury associated with renal crystal formation.

Objective: To investigate whether calcium oxalate monohydrate (COM), a key element of hyperoxaluria, would induce renal cell injury through oxidative stress and also whether certain antioxidants could prevent chemically induced renal crystal formation in rats.

Materials And Methods: COM-exerted oxidative stress on the kidney epithelial Madin-Darby canine kidney cells was assessed using the lipid peroxidation assay. Glyoxalase I (Gly-I) activity was also determined.

Induction of cell death in renal cell carcinoma with combination of D-fraction and vitamin C.

Hypothesis: Although several conventional therapeutic options for advanced renal cell carcinoma (RCC) are currently available, the unsatisfactory outcomes demand establishing more effective interventions. D-fraction (PDF), a bioactive proteoglucan of Maitake mushroom, demonstrates anticancer and immunomodulatory activities, which are also shown to be potentiated by vitamin C (VC). We thus hypothesized that a combination of PDF and VC (PDF + VC) could be an alternative approach to more effectively inhibit the growth of RCC.

Laparoscopic-assisted surgical reconstruction of a rare congenital abdominal wall defect in two children misdiagnosed with prune-belly syndrome.

Purpose: Abdominal wall laxity is typically associated with prune-belly syndrome (PBS). Incomplete forms of PBS have been rarely reported with only the abdominal wall laxity. Herein, we describe a rare congenital abdominal wall defect that has been confused with PBS and illustrate the laparoscopic-assisted surgical technique used for reconstruction.

Nephrotoxin-induced renal cell injury involving biochemical alterations and its prevention with antioxidant.

Background: Although nephrotoxic agents or nephrotoxins are known to induce acute renal cell injury, their cytotoxic action is not fully elucidated. It is thus crucial to explore such a cytotoxic mechanism and the increasing volume of reports indicated a significant involvement of oxidative stress. To test this possibility, we investigated if a nephrotoxin would exert oxidative stress, leading to renal cell injury accompanied by certain biochemical alterations.

Ureteroscopic and extirpative treatment of upper urinary tract urothelial carcinoma: a 15-year comprehensive review of 160 consecutive patients.

Unlabelled: Study Type--Therapy (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Upper urinary tract urothelial carcinomas (UTUC) have historically been treated with radical, extirpative surgery, primarily nephroureterectomy with bladder-cuff excision. In general, there has been growing interest in renal preservation, as evidenced by the broadening application of nephron-sparing surgery for renal parenchymal tumours.

Additively enhanced antiproliferative effect of interferon combined with proanthocyanidin on bladder cancer cells.

Although interferon (IFN) has been often used as immunotherapy for bladder cancer, its efficacy is rather unsatisfactory, demanding further improvement. Combination therapy is one of viable options, and grape seed proanthocyanidin (GSP) could be such an agent to be used with IFN because it has been shown to have anticancer activity. We thus investigated whether combination of IFN and GSP might enhance the overall antiproliferative effect on bladder cancer cells in vitro.

Amelioration of renal ischemia-reperfusion injury with a novel protective cocktail.

Purpose: Extended warm ischemia during partial nephrectomy can lead to considerable renal injury. Using a rat model of renal ischemia we examined the ability of a unique renoprotective cocktail to ameliorate warm ischemia-reperfusion injury.

Materials And Methods: A warm renal ischemia model was developed using 60 Sprague-Dawley® rats.

Attenuation of androgenic regulation by brefeldin A in androgen-responsive prostate cancer cells.

Objectives: To investigate the effects of an antibiotic brefeldin A (BFA) on androgen-regulated cellular events in androgen-responsive prostate cancer cells, focusing on PSA (prostate-specific antigen) status, cell growth, and bioactivity of androgen receptor (AR).

Materials And Methods: Androgen-responsive human prostate cancer LNCaP cells were employed and 5α-dihydrotestosterone (DHT) was used as an androgenic mediator to induce androgen-modulated cellular events. Effects of BFA on synthesis and secretion of PSA, cell growth, and AR activity were assessed using Tandem PSA assay, trypan blue exclusion method, and AR binding assay, respectively.
