Harvest and Primary Culture of Leptomeningeal Lymphatic Endothelial Cells.

Leptomeningeal lymphatic endothelial cells (LLECs) are a recently discovered intracranial cellular population with a unique distribution clearly distinct from peripheral lymphatic endothelial cells. Their cellular function and clinical implications remain largely unknown. Consequently, the availability of a supply of LLECs is essential for conducting functional research in vitro.

Imaging Vital and Non-vital Brain Pericytes in Brain Slices following Subarachnoid Hemorrhage.

Pericytes are crucial mural cells situated within cerebral microcirculation, pivotal in actively modulating cerebral blood flow via contractility adjustments. Conventionally, their contractility is gauged by observing morphological shifts and nearby capillary diameter changes under specific circumstances. Yet, post-tissue fixation, evaluating vitality and ensuing pericyte contractility of imaged brain pericytes becomes compromised.

[The effect of simvastatin on osteoblastic bionomics of rats].

Purpose: To study the effect of simvastatin on osteoblast proliferation, differentiation and mineralization and to explore the mechanism of stimulation of bone formation by simvastatin.

Methods: Six 8-hour healthy SD rats were used for the experiment. In order to harvest vital osteoblast, this research modified the traditional tissue piece method to culture primary osteoblast of rat calvarias.

Effects of soil amendments at a heavy loading rate associated with cover crops as green manures on the leaching of nutrients and heavy metals from a calcareous soil.

The potential risk of groundwater contamination by the excessive leaching of N, P and heavy metals from soils amended at heavy loading rates of biosolids, coal ash, N-viro soil (1:1 mixture of coal ash and biosolids), yard waste compost and co-compost (3:7 mixture of biosolids to yard wastes), and by soil incorporation of green manures of sunn hemp (Crotalaria juncea) and sorghum sudangrass (Sorghum bicolor x S. bicolor var. sudanense) was studied by collecting and analyzing leachates from pots of Krome very gravelly loam soil subjected to these treatments.
