Greenhouse operation and inside climate strongly depend on the outside weather. This implies that at least a year of data collection is required to cover the whole operational domain. Greenhouse-climate models calibrated with data limited to only a small region of the operating domain (weather and control), may therefore, produce erroneous predictions when applied to unfamiliar conditions. A co...
The purpose of this study was to determine the feasibilty of performing transcutaneous electrosigmoidography (TC-ESG). The study involved 19 healthy volunteers (11 men, 8 women; mean age 38.2 +/- 14.8 years). To validate the results of TC-ESG, the latter was performed simultaneously with intra-sigmoid ESG. TC-ESG was done also in five patients who underwent sigmoidectomy. The optimal position o...
Prediction of annual rice production in all the 31 districts of Tamilnadu is an important decision for the Government of Tamilnadu. Rice production is a complex process and non linear problem involving soil, crop, weather, pest, disease, capital, labour and management parameters. ANN software was designed and developed with Feed Forward Back Propagation (FFBP) network to predict rice production...
BACKGROUND AND OBJECTIVES A growing number of operations for sigmoid diverticulitis are being done laparoscopically. There is a paucity of data on the outcome of laparoscopy for sigmoid diverticulitis complicated by colonic fistula. The aim of this study was to compare the results of laparoscopic resection of sigmoid diverticulitis with and without colonic fistula. METHODS A retrospective rev...
BACKGROUND/AIMS Although multiple treatment options exist for the management of sigmoid colon volvulus, no study has examined the factors associated with successful endoscopic detorsion. This study aimed to examine the clinical course of patients with sigmoid colon volvulus and to identify factors related to successful endoscopic detorsion. METHODS This study included 30 cases (21 patients) o...
BACKGROUND We describe a standarized eight-step technique to perform sigmoid colectomy using the da Vinci robot (Intuitive Surgical, Sunnyvale, CA) in both the left upper and lower abdominal quadrants. MATERIALS AND METHODS Between March 2005 and June 2006, 11 robotic sigmoid colectomies were performed on patients with diverticulitis or cancer. The procedures were performed through 4 ports, u...
Case of a sigmoid colon cancer with metachronous metastases to the mesorectum and the abdominal wall
BACKGROUND Sigmoid colon cancer metachronous metastases commonly occur in the liver and lungs with sporadic reports also to the spleen, stomach, thyroid gland, abdominal wall and upper urinary tract. This is a rare case of metachronous metastases invading the mesorectum and the abdominal wall. CASE PRESENTATION A 72-year-old female underwent sigmoidectomy for stage I (T2N0 M0) sigmoid colon c...
Introduction Dose calculation of tumor and surrounding tissues is essential during prostate brachytherapy. Three radioisotopes, namely, 125 I, 103 Pd, and 131 Cs, are extensively used in this method. In this study, we aimed to calculate the received doses by the prostate and critical organs using the aforementioned radioactive seeds and to investigate the effect of scattering contribution for t...
Abstract Evidence suggests that sigmoid-colonic motility is increased in patients with irritable bowel syndrome (IBS). 5-Hydroxytryptamine (5-HT) plays a role in the control of motility, but its involvement in the dysmotility seen in IBS remains unclear. To investigate the relationship between platelet depleted plasma 5-HT (PDP 5-HT) concentration and sigmoid-colonic motility in patients with I...
A 48-year-old woman was admitted with 15-mo history of abdominal pain, diarrhea and hematochezia, and 5-mo history of defecation difficulty. She had been successively admitted to nine hospitals, with an initial diagnosis of inflammatory bowel disease with stenotic sigmoid colon. Findings from computed tomography virtual colonoscopy, radiography with meglumine diatrizoate, endoscopic balloon dil...
