Experimental Colonic Obstruction and Anastomotic Healing
… presentation and in most cases due to malignant obstruction of the left colon. Immediate resection and anastomosis is feasible but carries a 3-fold higher risk of developing anastomotic leakage compared to elective surgery. Anastomotic healing in patients can be evaluated as clinical outcome and …

Poiesis and Obstruction in Art Practice
… which was not there before’, in the context of obstruction in studio practice. It poses the question ‘Is there a methodology that engages with obstruction which in turn calls new work’? In this thesis, the concept of poiesis emerging from the late Dr. Murray Cox’s ‘Aeolian Mode’, is analyzed …

Studies in Experimentally Produced High Intestinal Obstruction
The cause of death in intestinal obstruction is unknown. | The occurrence of intestinal obstruction as an acute intra-abdominal condition is probably as old as the race itself. The Hippocratic facies— | "... a sharp nose, hollow eyes, collapsed temples; the ears cold, contracted and their lobes …

The odd chern character and obstruction theory
… is is analyzed. Our presentation uses the obstruction theory definition Chern characteristic classes in order to emphasize the connections with the even-degree component (see Theorem 4.3.1) and leads to a natural justification of the fundamental property of the Chern character, i.e. of …

Surgery Improves Survival Among Patients With Intestinal Obstruction
Introduction: Intestinal obstruction is a common cause of hospital admissions and carries a mortality rate around 5%. We hypothesized that surgical intervention reduces mortality among these patients. Methods: We conducted a retrospective cohort study using the 2006 Nationwide Inpatient Sample …

Ambient Obstruction Solitons And Homogeneous Gradient Bach Solitons
… associated with the Bach tensor and the ambient obstruction tensor. The Bach tensor is realized as the gradient of the Weyl energy functional. Consequently, the minimizers of the Weyl energy are the metrics where the Bach tensor vanishes. There are a number of metrics that are widely considered …

Diffusion-driven flows due to an obstruction layer
… boundaries, it is shown here that even an obstruction layer with only vertical walls produces a type of diffusion-driven flow. This is demonstrated through the execution of a dye test. Additionally, the influence that impermeable obstructions have on the density evolution of a stratified …

Comparative efficacy of three common treatments for equine recurrent airway obstruction
Objective - evaluate horses with acute airway obstruction using three treatment regimens: tapering doses of dexamethasone (DEX), environmental modification (ENV), and a combination of both treatments (DEX + ENV) by analyzing clinical parameters, pulmonary function testing, bronchoalveolar lavage …

Stem-Cell Like PDGFR? Cells are Induced in Chronic Intestinal Partial Obstruction
… To accomplish this, a chronic partial intestinal obstruction surgery was used to stimulate intestinal tissue, and changes to cellular phenotype and behavior were characterized using histology and immunofluorescence. We found that the injury induced smooth muscle hypertrophy, which involved the …

Small bowel obstruction and toxicity of a new model of adhesion prevention
Abstract Background: Small bowel obstruction (SBO) is a common surgical diagnosis. If no signs of strangulation are evident, the majority of the patients can be conservatively managed. Approximately one third of the patients need surgical treatment and there is a need for early parameters that can …

Identification of Differentially Expressed Genes in a Rat Unilateral Ureteral Obstruction Model
일측성 요관 폐색(unilateral ureteral obstruction, UUO)은 신부전을 유도하는 동물 모델로 신장질환의 다양한 특징들을 관찰할 수 있다. 본 연구는 UUO 모델에서 신부전에 관여하는 유전자를 규명하고자 Wistar 백서의 좌측 요관을 결찰하여 UUO 모델을 만들고 결찰하지 않은 우측 신장을 대조군인 contralateral unobstructed kidney(CUK)로 하여 24시간 후, 이들 신장에서 나타난 유전자 변화를 annealing control primer(ACP)를 이용한 …

Stentless pyeloplasty for paediatric uretero-pelvic junction obstruction: a 15- year experience
… for congenital ureteroplevic junction obstruction. Methods We retrospectively reviewed the data of paediatric patients who underwent dismembered pyeloplasty due to congenital ureteropelvic junction obstruction (UPJO) between January 2008 and July 2022. Patients' demographics, …

Exploring the effects of an obstruction on the evolution of the Rayleigh-Taylor Instability
This thesis discusses the effect of an obstruction on the evolution of the Rayleigh-Taylor instability in a confined geometry at low Atwood numbers. Laboratory experiments are the principal method of investigation, though these data are supplemented with implicit large eddy simulations (ILES). The …

Management of left-sided malignant colonic obstruction : an audit of a stent based protocol
… of selected cases of malignant colonic obstruction. Since 2005, we have used endoscopic decompression with SEMS as the primary treatment of all patients with left-sided obstructing colorectal cancer, in the absence of perforation. The purpose of the study was to assess the safety and …
