OBJECTIVES Just as people with the same weight can have different body builds, woods with the same wood density can have different anatomies. Here, our aim was to assess the magnitude of anatomical variation within a restricted range of wood density and explore its potential ecological implications. METHODS Twig wood of 69 angiosperm tree and shrub species was analyzed. Species were selected ...

objective brain abscesses represent organized foci of suppuration within the parenchyma. here we report a 3 month-old girl with a very huge complicated cerebral abscess, and the course of treatment given. the patient's recovery was excellent. the follow up mri showed only subtle porencephalic changes as the only parenchymal sequelae, which may be due to cns plasticity in infants.

In order to find the possible role of intracellular contents in facilitating the supercooling capability of xylem parenchyma cells, changes in the temperature of supercooling levels were compared before and after the release of intracellular substances from beech xylem parenchyma cells by DTA. Various methods were employed to release intracellular substances from xylem parenchyma cells and all ...

PURPOSE To demonstrate the hemodynamic features of liver metastases using quantitative color mapping of the arterial enhancement fraction (AEF) and to investigate the feasibility of using the AEF to predict the chemotherapy response. MATERIALS AND METHODS Seventy-two patients with liver metastases (metastasis group) and 18 cancer-matched patients without liver metastases (non-metastasis group...

Arundinella hirta L. is a C(4) plant having an unusual C(4) leaf anatomy. Besides mesophyll and bundle sheath cells, A. hirta leaves have specialized parenchyma cells which look morphologically like bundle sheath cells but which lack vascular connections and are located between veins, running parallel to them. Activities of phosphoenolpyruvate and ribulose-1,5-bisphosphate carboxylases and phos...

The blood-brain barrier prevents infiltration of peripheral immunocompetent cells into the CNS under physiological conditions. Following brain trauma there is reported a rapid and massive immunological response. Our earlier data indicated that surgical brain injury causes breaking of brain parenchyma integrity and results in cell changes and death, astrogliosis and disruption of blood vessels. ...

Parenchyma–preserving hepatic resection in treatment of metastatic colorectal cancer: analysis the literature data and own experience accumulated

3640 Background: Liver metastasis often occurs in patients who undergo surgical removal of the primary colorectal tumor. The adhesion molecules, E-cadherin/catenin complex, are closely involved in the development and growth of metastatic tumors. Today, no data are available on the effect of chemotherapy on liver parenchyma. METHODS Thirty-nine patients (27 males and 12 females, with a mean ag...
