Farm Productions and Rural Landscapes

2017

Farm landscapes in the Philippines are dominated by rice and coconuts in most provinces. In a country of generally small farm holdings, rice, the staple food, is cultivated across the archipelago, even if corn plays a bigger role in the southern part of the country. In the mountains of northern Luzon, the Ifugao tribe have developed over several centuries a remarkable landscape of rice terraces on steep slopes, but most of the rice is grown in the plains of Central Luzon around Manila. The coconut “tree of life”, most abundant in Quezon and Bicol, is used in many different ways, from food to construction materials. Bananas and pineapple are the leading export productions, mostly grown on la…

In vitro bioavailability of iron and calcium in cereals and derivatives: A review

2016

Cereals are a staple food in both developed and developing countries, and are considered to be the best vehicle for iron and calcium fortification, as an important strategy for combating dietary deficits. Inadequate dietary intake of iron and calcium is related to a number of disease conditions such as anemia, osteoporosis, hypertension, and different cancers. From a nutritional point of view, it is interesting to know not only the amount of minerals consumed, but also their bioavailability. The present study reviews the current knowledge on the in vitro bioavailability of iron and calcium in cereals, placing emphasis on the methodologies used and on the influence of dietary factors and foo…

Simplified Orthotopic Ileocecal Pouch (Mainz Pouch) for Bladder Substitution

2003

Objective To report operative modifications that render construction of the orthotopic Mainz pouch more simple, namely formation of the pouch using absorbable staples and utilization of the ileocecal valve as an antireflux mechanism. Patients and methods Between January 2001 and May 2002 out of 92 cystectomy cases, 21 patients (20 males and 1 female) underwent a simplified orthotopic Mainz pouch. The ureters were implanted via Wallace or Nesbit technique in the supravalvular portion of the ileocecal valve. The mean (range) age was 58 (43 - 74) years and the mean follow-up is 11.6 months (range 1 - 27). Results No staple-related complications were encountered. Four renal units (8.8 %) were d…

I MOMENTI STORICI DI UNA FREQUENTE PATOLOGIA ANALE: LE EMORROIDI

2004

In this report the authors outline the main historical aspects of haemorrhoids after a thorough review of the literature. The first texts concerning haemorrhoids are the ancient Egyptian papyruses. The twenty centuries of the history of haemorrhoids are marked by multiple pathogenetic theories, and of these the vascular and the sliding of the anal mucosa are still valid. From an analysis of the historical texts and the most recent publications, we deduce that the principles of therapy are substantially unchanged since the days of Hippocrates. In conclusion, we can say that, as in ancient times, the therapy of haemorrhoids is based on three fundamental approaches: surgical treatment, ambulat…

Predictors of complications and mortality following left colectomy with primary stapled anastomosis for cancer: results of a multicentric study with …

2018

Aim Reports detailing the morbidity-mortality after left colectomy are sparse and do not allow definitive conclusions to be drawn. We aimed to identify risk factors for anastomotic leakage, perioperative mortality and complications following left colectomy for colonic malignancies. Method We undertook a STROBE-compliant analysis of left colectomies included in a national prospective online database. Forty-two variables were analysed as potential independent risk factors for anastomotic leakage, postoperative morbidity and mortality. Variables were selected using the 'least absolute shrinkage and selection operator' (LASSO) method. Results We analysed 1111 patients. Eight per cent of patient…

Duodenal Atresia Repair Using a Miniature Stapler Compared to Laparoscopic Hand-Sewn and Open Technique

2019

Abstract Background: Laparoscopic duodenal atresia (DA) repair is a demanding procedure that requires performing a watertight anastomosis in a small working space. Drawbacks of the approach have be...

Cecal Resection with Bipolar Sealing Devices in a Rat Model

2018

Background: Bipolar sealing devices are routinely used to seal blood vessels. The aim of the study is to evaluate the feasibility and safety of colonic sealing with the use of the bipolar energy devices in rats as model for experimental appendectomy. Methods: Seventy-five male Wistar rats underwent a cecal resection with four different bipolar sealing devices or a linear stapler. The harvesting procedure was performed immediately or at postoperative day (POD) 7. The sealing front bursting pressure (BP) was measured in both groups. At POD7, the resection line was clinically examined and the hydroxyproline (HDP) levels were determined. Hematoxylin and Eosin (H&E) staining was used for histopa…

Technical characteristics can make the difference in a surgical linear stapler. Or not?

2015

Background Anastomotic leak (AL) after gastrointestinal surgery is a severe complication associated with relevant short- and long-term sequelae. Most of the anastomosis are currently performed with a surgical stapler that is required to have appropriate characteristics to guarantee good performances. The aim of our study was to evaluate, in the laboratory, pressure resistance and tensile strength of anastomosis performed with different surgical linear staplers, available in the market. Materials and methods We have been studying three linear staplers, with diverse cartridges and staple heights, of three different companies, used for gastrointestinal anastomosis and gastric or intestinal clo…

A multiscale approach to automatic and unsupervised retinal vessel segmentation using Self-Organizing Maps

2016

In this paper an automatic unsupervised method for retinal vessel segmentation is described. Self-Organizing Map, modified Fuzzy C-Means, STAPLE algorithms and majority voting strategy were adopted to identify a segmentation of the retinal vessels. The performance of the proposed method was evaluated on the DRIVE database.
