Dietary n-3 Fatty Acids Inhibit Fever Induced by Inflammation in the Rat

Modification of endogenous eicosanoid synthesis by dietary n-3 fatty acid supplementation reduces febrile responses, but the mechanisms underlying these effects in vivo have not been determined. In the present study, local inflammation was induced by intramuscular injection ofturpentine in rats fed control or n-3 supplemented diets for 8-9 weeks. In animals fed the control diet...

Wildlife Underpass Use and Environmental Impact Assessment: A Southern California Case Study

Environmental planners often rely on transportation structures (i.e., underpasses, bridges) to provide connectivity for animals across developed landscapes. Environmental assessments of predicted environmental impacts from proposed developments often rely on literature reviews or other indirect measures to establish the importance of wildlife crossings. Literature-based...

Neuropsychology and Advances in Memory Function

Recent developments in the functional and neural bases of several aspects of memory are described including long term cortical memory storage, the transition from immediate to permanent memory mediated by medial temporal structures, working memory, memory retrieval, and implicit memory. These are linked to current data on the nature of anterograde and retrograde amnesia in the...

Cholecystobronchocolic Fistula: A Late Complication of Biliary Sepsis

A case of a 48 year old woman presenting with bilioptysis due to a cholecystobronchocolic fistula is reported. Bilioptysis is a rare complication of biliary fistulae, with a high mortality due to chemical pneumonitis. Bronchospasm and rapid respiratory failure may ensue if aggressive management is not adopted. The site of fistulation is established by cholangiography, preferably...

The Transmission of Bulk Power Over Long Distances

Circular, plate, radial and coaxial arrangements for phases of double circuit transmission lines are proposed. Power transmission over long distances depends on the mutual effect between each two respective phases. A theoretical analysis for voltage, power and current along such lines is presented. The general constants for each configuration are evaluated, as well as the maximum...

A simple and flexible modification of Grünwald–Letnikov fractional derivative in image processing

In image processing, edge detection and image enhancement can make use of fractional differentiation operators, especially the Grünwald–Letnikov derivative. In this paper, we present a modified Grünwald–Letnikov derivative to enhance more and detect better the edges of an image. Our proposed fractional derivative is very flexible and can be easily performed. We present some...

Analysis of the Association of A Heat Shock Protein70-1 Gene Promoter Polymorphism With Myocardial Infarction and Coronary Risk Traits

Heat shock proteins (HSP) are induced during coronary ischaemia, and abnormal expression of one HSP gene may cause hypertension in rats, We examined association of a promoter polymorphism in the major stress-inducible hsp70 gene (hsp70-1 or HSP70A1) on chromosome 6 (p21.3) with coronary disease traits, This C→A base substitution (AAACCCC) is at nucleotide position -110 in the...

Symptomatic Improvement of Gastroduodenal Crohn’s Disease with Omeprazole

Four patients with ileal Crohn’s disease presented with abdominal pain aggravated by food, a mean weight loss of 5.5 kg (range 4 to 7) and ulceration of the antrum and/or duodenum at gastroscnpy, without radiological features of mechanical obstruction . The endoscopic and histological appearance of the ulcers was consistent with Crohn's disease. Omeprazole 40 mg daily was...

Outcomes of Asthma Education: Results of a Multisite Evaluation

BACKGROUND: This observational study compared the effectiveness of a standardized adult asthma education program administered in a variety of sites and practice settings on health care utilization, absenteeism, amount of leisure time missed and quality of life (using the Medical Outcomes Study 36-Item Short Form 1.0 [SF-36]).

Comparison of Various Turbulence Models in Rotating Machinery Blade-to-Blade Passages

Numerical calculations on four blade passages are done using Q3D Navier-Stokes solver with a simple mixing length turbulence model and two more advanced transport-equation approaches. Mixing length is simple and cheap but crude, while more sophisticated transport approaches are more physical but more expensive. Predicted results using different turbulent models are discussed and...

Methods for detecting methylation by SNP interaction in GAW20 simulation

To examine whether single-nucleotide polymorphism (SNP) by methylation interactions can be detected, we analyzed GAW20 simulated triglycerides at visits 3 and 4 against baseline (visits 1 and 2) under 4 general linear models and 2 tree-based models in 200 replications of a sample of 680 individuals. Effects for SNPs, methylation cytosine-phosphate-guanine (CpG) effects, and...

Studies on Novel Bisaryl Hydrazino-s-triazine Derivatives - Part 2

Various 2(4-chloro phenyloxy)-4,6-bisarylhydrazino-1,3,5-triazines(3a-f) were prepared by reaction of 2(4-chloro phenyloxy)-4,6-dichloro -1,3,5-triazine and various aryl hydrazine derivatives. All the 3a-f derivatives were characterized by elemental analysis and IR spectral studies. All the compounds were screened for microbial activity against gram-positive and gram-negative...

7-Ketocholesterol enhances leukocyte adhesion to endothelial cells via p38MAPK pathway

7-Ketocholesterol is a major dietary cholesterol oxidation product found in high concentrations in atherosclerotic plaques, which contribute to the development of atherosclerosis. This study aimed to investigate the effects of 7-ketocholesterol on endothelial inflammation, as well as the underlying mechanisms. Pretreatment of human umbilical vein endothelial cells (HUVEC) with 7...

« Principe 7 » De La Pédagogie, Effet Zeeman-Effet Prérequis, Architecture Pyramidale Du Système Lmd: Mise En Œuvre D’une Pédagogie Discriminatoire Pour Un Enseignement De Qualité

In this work, we demonstrate by analogy with the quantified levels of atomic systems, that the levels of education from elementary to Superior are "quantified". The transition of a learner from one level of instruction to another is analogous to an electronic transition between atomic levels. The notions of ground state, excited states and ionized state of atomic systems have...

Pain Management in Functional Gastrointestinal Disorders

Pain is a common feature in functional gastrointestinal disorders (FGID). An abnormally low visceral sensory threshold, as well as a number of central, spinal and peripheral pain-modulating abnormalities, have been proposed for this syndrome. Clinical aspects of pain associated with irritable esophagus, functional dyspepsia, biliary dysmotility, inflammatory bowel syndrome and...

Prediction of Adaptive Self-Regulatory Responses to Arthritis Pain Anxiety in Exercising Adults: Does Pain Acceptance Matter?

BACKGROUND: Exercising for ≥150 min/week is a recommended strategy for self-managing arthritis. However, exercise nonadherence is a problem. Arthritis pain anxiety may interfere with regular exercise. According to the fear-avoidance model, individuals may confront their pain anxiety by using adaptive self-regulatory responses (eg, changing exercise type or duration). Furthermore...
