Macrophages are key participants in angiogenesis. In this study on human brain tumors, we first investigated whether macrophage infiltration is associated with angiogenesis and malignant histological appearance. Immunostaining of macrophages and small vessels in resected glioma specimens indicated that numbers of infiltrating macrophages and small vessel density were higher in glioblastomas tha...
As the primary ecological construction measure on Loess Plateau, check dams play an essential role in developing agricultural production, improving people’s production and life, replenishing groundwater. Soil water infiltration is most important way to replenish groundwater dam land. In order investigate process of dams, empirical model suitable for simulation land was selected. The soil studie...

a 47 year-old female died after mitral valve replacement. post-cardiopulmonary bypass right ventricle was not able to pump despite good left ventricular contractility. at microscopic examination, diffuse right ventricular fatty infiltration was found. we found no previous report of this pathology in patients with mitral stenosis
the intraoperative care of pheochromocytomas can be difficult and lead to serious complications. we present a case of a 46 year-old female undergoing laparoscopic resection of pheochromocytoma, who was scheduled for surgery with phenoxybenzamine and amlodipin. under general anesthesia cardiovascular stability was achieved by peritumoral infiltration of lidocaine during resection.
Voorhees, M.E., 1986. Infiltration rate of bentonite mine spoil as affected by amendments of gypsum, sawdust and inorganic fertilizer. Reclam. Reveg. Res., 5: 483-490.
Measuring infiltration and leaching at the plot scale is difficult, especially for high hydraulic conductivity soils. Infiltration rate has been indirectly calculated at the plot scale by comparing surface runoff to rainfall. Direct measurement of infiltration and leaching beyond the point scale is typically limited to locations where land forming has been performed, e.g. infiltration ponds and...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
Hydrology in a patterned landscape is co-engineered by soil-disturbing animals and biological crusts
Water redistribution has a profound influence on dryland ecosystem function. This hydrological function is largely regulated by ecosystem engineers including biological soil crusts (biocrusts) which produce run-off, and burrowing animals, such as the greater bilby, whose pits capture water. We estimated the relative importance of these two ecosystem engineers in determining infiltration rates i...
Extended abstract 1- Introduction The Soil surface characteristics have significant effects on the erosion process. The wide areas of watershed soil surfaces are covered with considerable amounts of rocks and pebbles. Surface rock fragments, resulting in water connectivity, change during the erosion process. Rock fragments on the soil surface may increase the infiltration and reduce soil loss...
