the production of reactive oxygen species (ros) in plants under low temperature stress cause damage to plants. in order to evaluate of antioxidant responses of page mandarin young trees (two years old) on different rootstocks under low temperatures, an experiment was conducted in a factorial plan based on completely randomized design. treatment of temperatures were at seven levels include 9, 6,...

OBJECTIVE Hypercholesterolemia is a major risk factor for coronary artery disease. Therapeutic lifestyle changes include dietary modifications such as inclusion of phytosterols, which effectively lowers low-density lipoprotein (LDL) cholesterol in margarines and other fats. Their effectiveness in nonfat moieties is not yet established. The aim of this study was to examine if phytosterols alter ...

In Southern California the Valencia orange (Citruis sinensis, L.) attains maximum orange rind color during winter and regreens s-omewhat by harvest time the following summer. The degree of regreening has been correlated with temperature patterns and with nitrogen nutrition (2, 5). It has also been reported (3) that applications of potassium gibberellate (KGA) to Valencia trees were associated w...

Objective—Hypercholesterolemia is a major risk factor for coronary artery disease. Therapeutic lifestyle changes include dietary modifications such as inclusion of phytosterols, which effectively lowers low-density lipoprotein (LDL) cholesterol in margarines and other fats. Their effectiveness in nonfat moieties is not yet established. The aim of this study was to examine if phytosterols alter ...

Introduction: Death from cardiovascular diseases is one of the leading causes of death in the elderly; Although the role of exercise and herbs in heart health has been reported, their cellular-molecular mechanisms are not yet well understood. Therefore, the aim of the present study was to investigate the effect of eight weeks of continuous exercise with moderate intensity and intense periodicit...

BACKGROUND We assessed the bioavailability of orange juice (poly)phenols by monitoring urinary flavanone metabolites and ring fission catabolites produced by the action of the colonic microbiota. OBJECTIVE Our objective was to identify and quantify metabolites and catabolites excreted in urine 0-24 h after the acute ingestion of a (poly)phenol-rich orange juice by 12 volunteers. DESIGN Twel...

Agent Orange is at the core of an ongoing controversy involving veterans organizations that want the Federal govenment to complete a study intended to examine possible lasting health effects of exposure to this herbicide during the Vietnam War. Many Vietnam veterans are quite concerned that various health problems they have suffered may be associated with exposure to Agent Orange in Vietnam. Th...

the aim of this study was to determine the inhibitory effects of feed ingredients on protease activities of argyrosomus regius larvae using in vitro techniques. a. regius larvae fed on a commercial feeding procedure were sampled thirteen times, during the sampling period (from 3 to 32 days after hatching (dah)). the differences observed in protease activities of meagre larvae during the samplin...

The intracellular calcium concentration ([Ca2+])i of astrocytes within rat hippocampal slices was measured during simultaneous hypoxia and hypoglycemia to examine the early intracellular signaling events induced by this in vitro model of ischemia. Hypoxia-hypoglycemia for 3.3-7.5 min evoked [Ca2+]i increases in astrocytes iontophoretically loaded with calcium orange (11/14 slices; 2.5 min to pe...
