Dole et al. (1984) have suggested that the coronary zero flow pressure results from critical closure of microvessels, which they model as pressure-dependent nonlinear resistors. This view differs from the vascular waterfall interpretation of coronary hemodynamics in which microvessels are modeled as collapsible tubes. It is important to determine which model is more descriptive, for an understa...

INTRODUCTION: The purpose of this study was to evaluate long-term holistic outcomes for children with cleft lip and/or palate (CL/P) in North Carolina using a multidisciplinary, mixed-methods approach. This entailed crosssectional evaluation of population-based data, longitudinal evaluation of clinical, and qualitative/semi-quantitative survey-based evaluation of outcomes from the perspective o...

Results: About 57% (252 out of 441) of the Health Care Workers (HCW) had at least one episode of NSI in the preceding 12 months .Majority were Nurses (81%).The commonest devices involved was suturing needle (41%) and hypodermic needles (44%).Majority of the NSI (46 %) occurred during use of needle on the patient. About (85%) of the HCW didn’t report the injury. Hepatitis B vaccination rate was ...

Background The relationship between diabetes mellitus (DM) and cardiac complications has never been systematically studied in thalassemia major (TM). The aim of this crosssectional study was to evaluate in a large historical cohort of TM in the cardiovascular magnetic resonance (CMR) era if DM was associated with an higher prevalence and risk of heart complications, also regardless to the prese...

Understanding the role (particularly the mechanisms of action) that physical activity plays in the development of hypertension among blacks is important for risk reduction efforts and public policy actions, especially because blacks bear the highest burden of hypertension, and crosssectional studies suggest that physical activity may be associated with reduced hypertension in blacks (1). We the...

Materials and methods EMBASE, PubMed, Web of Science, and the Cochrane Library were searched by two independent reviewers for all relevant studies published from 1945 to October 2014. Studies were included if they met all of the following inclusion criteria: 1) Prospective or retrospective cohort study, case-cohort, case-control design, or crosssectional study; 2) Measurement of plasma PAI-1 (a...

We are developing a new method using ultrasonic longitudinal and torsional vibration of a hollow-type stepped horn for hole machining. We foresee that the equipment can be simplified and miniaturized. In this paper, ultrasonic vibration sources of a hollow-type stepped horn without a diagonal slits vibration converter and with a diagonal slits vibration converter are used. The longitudinal and ...

Background. Sclerostin, a glycoprotein, plays key role in regulating bone mass. In this study, sclerostin levels the gingival crevicular fluid (GCF) were assessed patients with Stage III Grade C generalized periodontitis (SIII-GC) and B (SIII-GB). Methods. This cross-sectional study included 30 participants divided equally into three groups: group I (gingival health), II (SIII-GC), Clinical per...
