Highly ordered mesoporous graphitic carbon was synthesized from a simple surfactant-assisted nanocasting route, in which ordered mesoporous silica SBA-15 maintaining its triblock copolymer surfactant was used as a hard template and natural soybean oil (SBO) as a carbon precursor. The hydrophobic domain of the surfactant assisted SBO in infiltration into the template's mesoporous channels. After...

A bezoar is a collection of indigestible material found in the alimentary canal, which can cause mechanical obstruction of the gastrointestinal tract. Phytobezoar is a variant composed of mostly plant material and indigestible fiber. Phytobezoar is a rare cause of small bowel obstruction (SBO) and happens more commonly in patients with risk factors predisposing to impaired gastrointestinal moti...

Bimolecular reactions of the antimony(V) porphyrin complexes SbO(tpp)OH, 1 and SbO(oep)OH, 2 with tetra-n-butylammonium hydroxide were investigated at 298 K in acetonitrile solution (tpp, dianion of 5,10,15,20-tetraphenylporphyrin and oep, dianion of 2,3,7,8,12,13,17,18-octaethylporphyrin). Spontaneous nucleophilic addition of hydroxide ions to the non-oxidized porphyrin macrocycle leads to nov...

We consider derivative-free black-box global optimization of expensive noisy functions, when most of the randomness in the objective is produced by a few influential scalar random inputs. We present a new Bayesian global optimization algorithm, called Stratified Bayesian Optimization (SBO), which uses this strong dependence to improve performance. Our algorithm is similar in spirit to stratific...

Intestinal obstruction is one of the most perplexing clinical situations encountered by a surgeon in the emergency room. Computed tomography (CT) has become the most useful and powerful tool in diagnosing intestinal obstructions. CT was reported to yield sensitivities of 81% to 96%, with up to 96% specificity and 95% accuracy for the diagnosis of small bowel obstruction (SBO) [1]. The most comm...

Adenosine is a powerful direct coronary vasodilator with a very short half-life that has been shown to be effective in avoiding and reversing no reflow. We report an immediate successful recanalization of an occluded major side branch after stenting with acute intracoronary adenosine administration. The beneficial effect of adenosine may imply that the side branch occlusion (SBO) in this case c...

BACKGROUND A congenital adhesion band is a rare condition, but may induce a small bowel obstruction (SBO) at any age. However, only a few sporadic case reports exit. We aimed to identify the clinical characteristics of congenital adhesion band manifesting a SBO stratified by age group between pediatric and adult patients. METHODS The medical records of all patients with a SBO between Jan 1, 2...

Abstract Introduction The most common causes of Small bowel obstruction (SBO) in adults are adhesions, hernias, cancer, Crohn's, Diverticulitis, volvulus, etc; children, intussusception. Overall mortality is 10%, increasing to 30% with complications. Urgent investigation, aggressive medical management and appropriate timely surgery key successful outcome. Aim We present a patient 4 due single p...

Abstract Aim Higher than average emergency laparotomy mortality rates had been identified via the National Emergency Laparotomy Audit (NELA), at a particular hospital. Small bowel obstruction (SBO) is commonest cause for laparotomy. The aim of this project was to evaluate management SBO, and implement changes reduce operative SBO rate. Method NELA used assess cases between 1st Dec 2018 - 30th N...
