INTRODUCTION: The introduction of total mesorectal excision (TME) in the 1980s was pivotal in the surgical treatment for rectal carcinoma (RC). Routinely applied TME led to a significant reduction in the incidence of local recurrences. The purpose of our paper is to present the results of our non-randomized study comparing prospectively acquired data from radical resection / rectal extirpation using classic open access, laparoscopy and da Vinci robotic system. METHOD: The study group included 116 patients with RC who underwent radical surgical treatment between 1/2014-12/2016, after which the collected resection specimens were assessed in pathology laboratories of the referring hospital using the Quirkes protocol...

This study evaluates the potential of laser induced breakdown spectroscopy (LIBS) coupled with chemometrics to develop a quantification model for rubidium (Rb) in minced beef. A LIBSCAN 150 system was used to collect LIBS spectra of minced beef samples. Beef liver was used to spike the Rb levels in minced beef. All samples were dried, powdered and pelleted using a hydraulic press. Measurements were conducted by scanning 100 different locations with an automated XYZ sample chamber. Partial least squares regression (PLSR) was used to develop the calibration model, yielding a calibration coefficient of determination (Rc(2)) of 0...

The ginsenoside Rh2, a pharmaceutically active component of ginseng, is known to have anticancer and antitumor effects. However, white ginseng and red ginseng have extremely low concentrations of Rh2 or Rh2-Mix [20(S)-Rh2, 20(R)-Rh2, Rk2, and Rh3]. To enhance the production of food-grade ginsenoside Rh2, an edible enzymatic bioconversion technique was developed adopting GRAS host strains. A β-glucosidase (BglPm), which has ginsenoside conversion ability, was expressed in three GRAS host strains (Corynebacterium glutamicum, Saccharomyces cerevisiae and Lactococus lactis) by using a different vector system...

Background: Renal colic (RC) is one of the most common reasons for emergency department (ED) visits. Although RC is associated with high ambient temperature and with physiological changes that occur during fast, the literature onbetween Ramadan and RC incidence is scarce. Methods: We obtained health data of patients visited the emergency department (ED) of a large tertiary center during the years 2004-2015, with a primary diagnosis of RC. To estimate the association of RC and Ramadan, we utilized bi-weekly RC incidence Poisson models adjusted for ambient temperature and seasonality in two ethnic groups residing in the region: Muslims and Jews...

BACKGROUND: Gallbladder cancer detected incidentally after cholecystectomy (IGBC) currently is the most common diagnosis of gallbladder cancer, and oncologic extended resection (OER) is recommended for tumors classified higher than T1b. However, the precise prognostic significance of residual cancer (RC) found at the time of OER has not been well established. This analysis aimed to determine the prognostic impact of RC found in patients with IGBC undergoing OER. METHODS: Outcomes for IGBC at a center for a low-incidence country (USA) and a high-incidence country (Chile) between January 1999 and June 2015 were analyzed...

Understanding the spatiotemporal structure of most probable fluctuation pathways to rarely occurring states is a central problem in the study of noise-driven, nonequilibrium dynamical systems. When the underlying system does not possess detailed balance, the optimal fluctuation pathway to a particular state and relaxation pathway from that state may combine to form a looplike structure in the system phase space called a fluctuation loop. Here, fluctuation loops are studied in a linear circuit model consisting of coupled RC elements, where each element is driven by its own independent noise source...

BACKGROUND: The incidence of halitosis has a prevalence of 22-50% throughout the world and is generally caused by anaerobic oral microorganisms, such as Fusobacterium nucleatum, Clostridium perfringens, and Porphyromonas gingivalis. Previous investigations on the structure-activity relationships of ginsenosides have led to contrasting results. Particularly, the antibacterial activity of less polar ginsenosides against halitosis-related bacteria has not been reported. METHODS: Crude saponins extracted from the Panax quinquefolius leaf-stem (AGS) were treated at 130°C for 3 h to obtain heat-transformed saponins (HTS)...

Given the lack of randomized evidence comparing trimodal therapy (TMT) to radical cystectomy (RC) for muscle-invasive urothelial carcinoma of the bladder (UCB), we performed an observational cohort study to examine the comparative effectiveness of these two definitive treatments. Within the National Cancer Data Base (2004-2011),we identified 1257 (9.8%) and 11 586 (90.2%) patients who received TMT and RC, respectively. Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier analysis showed that median overall survival (OS) was similar between the TMT (40 mo, 95% confidence interval [CI] 34-46) and RC groups (43 mo 95% CI 41-45; p=0...

PURPOSE: Radical cystectomy (RC) has become increasingly regionalized to high-volume hospitals. Our objective was to describe changes in regional market concentration and the distribution of RCs among hospitals, and examine how these changes affect patient travel distance to surgery. MATERIALS AND METHODS: We used the surveillance, epidemiology, and end results-Medicare database to identify patients who had RC for bladder cancer from 2001 to 2011. We defined RC market concentration within each Hospital Referral Regions (HRR) in surveillance, epidemiology, and end results using the Hirschman-Herfindhal Index...
