A rapid one-step procedure for purification of mononuclear and polymorphonuclear leukocytes from human blood using a modification of the Hypaque-Ficoll technique.
A one-step procedure for purification of mononuclear and polymorphonuclear cells from human blood is described. It is a modification of the Hypaque-Ficoll method with density of 1.095 g/ml.Expand

Stimulation of p38 Phosphorylation and Activity by Arachidonic Acid in HeLa Cells, HL60 Promyelocytic Leukemic Cells, and Human Neutrophils
Although it is well appreciated that arachidonic acid, a second messenger molecule that is released by ligand-stimulated phospholipase A2, stimulates a wide range of cell types, the mechanisms thatExpand

Ethylene Role in Plant Growth, Development and Senescence: Interaction with Other Phytohormones
The complex juvenile/maturity transition during a plant’s life cycle includes growth, reproduction, and senescence of its fundamental organs: leaves, flowers, and fruits. Growth and senescence ofExpand

Drought, abscisic acid and transpiration rate effects on the regulation of PIP aquaporin gene expression and abundance in Phaseolus vulgaris plants.
BACKGROUND AND AIMS Drought causes a decline of root hydraulic conductance, which aside from embolisms, is governed ultimately by aquaporins. Multiple factors probably regulate aquaporin expression,Expand

Bacterial Lipopolysaccharide and Tumor Necrosis Factor Alpha Synergistically Increase Expression of Human Endothelial Adhesion Molecules through Activation of NF-κB and p38 Mitogen-Activated Protein
ABSTRACT One of the recognized associations of bacterial infection with cardiovascular events is the activation of endothelium and upregulation of adhesion molecules. The two major proinflammatoryExpand

Role of abscisic acid in perianth senescence of daffodil (Narcissus pseudonarcissus"Dutch Master").
Daffodil (Narcissus pseudonarcissus L. 'Dutch Master') flowers detached at the base of their ovaries and held with their cut ends in 10-100 microM abscisic acid (ABA) senesced prematurely. SymptomsExpand

Current understanding on ethylene signaling in plants: the influence of nutrient availability.
The plant hormone ethylene is involved in many physiological processes, including plant growth, development and senescence. Ethylene also plays a pivotal role in plant response or adaptation underExpand

Thidiazuron —a potent inhibitor of leaf senescence in Alstroemeria
Abstract The time to flower senescence and leaf yellowing in 20 cut flower cultivars of Alstroemeria was studied. In deionized water (DI), the time to abscission of the first petal ranged from 9 toExpand

Synthesis and Surface Expression of CD14 by Human Endothelial Cells
ABSTRACT Previous studies have reported that human vascular endothelial cells lack the membrane-bound lipopolysaccharide (LPS) receptor, CD14 (mCD14). By optimizing assay conditions, including theExpand
