The structure and transport properties of pit membranes at the interface between the metaxylem and xylem parenchyma cells and the possible role of these pit membranes in solute transfer to the phloem were investigated. Electron microscopy revealed a fibrillar, almost tubular matrix within the pit membrane structure between the xylem vessels and xylem parenchyma of leaf blade bundles in rice (Or...

central venous catheter (cvc) insertion is a practical way to assess patients hemodynamic specially in cardiovascular surgery but this relatively simple junior level procedure is not risk free and its common reported complications include; pneumothorax, hydrothorax, hemothorax, local hematoma, cardiac tamponade, vascular injury, thrombosis, embolism, and catheter disruption. here in this articl...

depression is a mental disorder that results from changes in the central nervous system (cns) that may result from immunological abnormalities. according to the world health organization, major depression will become the leading cause of disability worldwide. accumulating evidence has indicated the existence of reciprocal communication pathways between nervous, endocrine and immune systems. the...

a $p$-group $g$ is $p$-central if $g^{p}le z(g)$‎, ‎and $g$ is‎ ‎$p^{2}$-abelian if $(xy)^{p^{2}}=x^{p^{2}}y^{p^{2}}$ for all $x,yin‎ ‎g$‎. ‎we prove that for $g$ a finite $p^{2}$-abelian $p$-central‎ ‎$p$-group‎, ‎excluding certain cases‎, ‎the order of $g$ divides the‎ ‎order of $text{aut}(g)$‎.
