[email protected] Abstract – Previous studies have shown that irrigation can impact the near-surface climate, but none refer to the differences in the impacts of irrigation types such as flooding and spraying. In this study, we add a novel irrigation module to the recently released community land model 4.0 and simulate irrigation in two ways: first, by spraying water...

INTRODUCTION The purpose of this study was to compare the debridement efficacy of EndoVac irrigation versus conventional needle irrigation in vivo. METHODS Seven adult patients with a total of 22 matched pairs of single-canaled vital teeth with fully formed apices were recruited. Canals were instrumented to a master apical file size #40/.04 taper. One tooth from each matched pair was irrigate...

A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.

OBJECTIVE Ephrin-B2 plays a key role in vascular development. The purpose of this study was to elucidate the molecular mechanisms of ephrin-B2 signaling through the EphB receptor in endothelial cells and to determine whether ephrin-B2 contributes to in vivo angiogenesis in adult mice. METHODS AND RESULTS A chemotaxis assay on a polycarbonate membrane revealed that ephrin-B2/Fc chimeric protei...

The effect of dietary riboflavin (B2) supplementation and selenium (Se) source on the performance and Se metabolism of weanling pigs was studied. Pigs fed a B2-supplemented (10 mg/kg) casein-glucose diet for 18 d gained faster than pigs fed the B2-unsupplemented diet. Percentage active erythrocyte glutathione reductase (GR) declined rapidly when pigs were placed on the B2-unsupplemented diet an...

PURPOSE Cyclin B2, a G(2)-M cyclin, is overexpressed in colorectal adenocarcinomas compared with the normal mucosa. This study examined the level of cyclin B2 overexpression according to the histologic findings and investigated the mechanism(s) and clinical implications of cyclin B2 overexpression in colorectal adenocarcinomas. EXPERIMENTAL DESIGN The immunoreactivity of the polyclonal antibo...

AIMS To devise an ex vivo model to test the efficacy of irrigation (static/dynamic) in removing a bio-molecular film from root canal walls. METHODOLOGY Forty human teeth with single straight canals were randomly allocated to two groups for static (n = 20) or dynamic (n = 20) irrigation. The root canals were prepared to different apical sizes (20, 40) and tapers (0.04, 0.08). The teeth were sp...
