As a natural and healthy beverage, tea is widely enjoyed; however, the pesticide residues in tea leaves affect the quality and food safety. To develop a highly selective and efficient method for the facile removal of pesticide residues, the subcritical butane extraction (SBE) technique was employed, and three variables involving temperature, time and extraction cycles were studied. The optimum ...

Obese individuals have an increased risk of developing depression. This study aimed to determine whether the "Senobi" breathing exercise (SBE), a stretching-breathing exercise that we have established, could relieve depression, especially in obese women. Forty premenopausal women, aged 40 to 49 years, participated in the present study. Twenty were healthy, and the other 20 were obese (body mass...

A density operator approach to generalized semiconductor Bloch equations (SBE) for one-time observables which includes carrier±carrier scattering effects is presented. The theoretical concept is based upon the quantum generalization of the BBGKY hierarchy for the reduced density operators. The advantage of our method is its simplicity and transparence ± to a large extent, derivations and physic...

background: little is known about how to introduce complex technologies like arthroscopy into low-income countries. thus, we compared low- versus high-resource intensive methods of teaching basic arthroscopic skills in a randomized controlled trial in haiti. methods: forty-eight haitian orthopaedic surgeons and residents attending an orthopaedic conference in haiti were block randomized to rece...

BACKGROUND AND OBJECTIVES The amount of metabolic acidosis measured through the standard base excess (SBE) has been shown to be an outcome marker and its improvement has been associated with better survival. We studied the mechanism of standard base excess variation in the first three days of intensive care unit (ICU) stay through the evaluation of independent variables of physico-chemical appr...

OBJECTIVES The exact role of atrial natriutetic peptide (ANP) in the pathogenesis of edema in nephrotic syndrome (NS) has not been fully elucidated. We aimed to investigate the possible contribution of ANP to edema formation in NS. METHODS We subjected 18 nephrotic subjects and 20 healthy volunteers to supine bicycle exercise (SBE), a maneuver that seemed to increase venous return and to enha...

BACKGROUND Crohn's disease (CD) frequently involves the small bowel. Actually, the diagnosis of CD is made by ileocolonoscopy (IC) and small bowel enteroclysis (SBE), while trans-abdominal bowel sonography (BS) and Tc-99m-HMPAO leukocyte scintigraphy (LS) are only partially used in spite of their minimal invasiveness. AIM to compare the diagnostic accuracy of these procedures for the diagnosi...

The slightly water-soluble flavonoid quercetin (QUE) and its inclusion with either beta-cyclodextrin (betaCD), hydroxypropyl-beta-cyclodextrin (HP-betaCD) or sulfobutyl ether-beta-cyclodextrin (SBE-betaCD) were investigated. The stoichiometric ratios and stability constants describing the extent of formation of the complexes have been determined by phase-solubility measurements; in all cases ty...

Proper education of a modeling and simulation professional meeting the extensive criteria imposed by the community poses significant challenges. In this paper, we explore the formation of a university-based education in modeling and simulation to meet the challenges. We examine the factors affecting the composition of a modeling and simulation course. Based on the anticipated consequences, we p...

Objective: In this trial, we intend to assess the effect of simulation-based education approach on advanced cardiovascular life support skills among medical students. Methods: Through convenient sampling method, 40 interns of Mashhad University of Medical Sciences in their emergency medicine rotation (from September to December 2012) participated in th...
