The purpose of the present study was to investigate the effect of ethanol extracts from red pepper seeds on the antioxidative defense system and oxidative stress in rats fed a high fat . high cholesterol diet. Rats were divided into four experimental groups which were composed of high fat . high cholesterol diet group (HF), high fat . high cholesterol diet with 0.1% ethanol extracts from red pe...

PURPOSE Once implanted, prostate brachytherapy seeds are vulnerable to loss and movement. A general estimation of these effects may be useful for making patient care decisions when seeds are lost after the post-implant scan. The goal of this work was to explore the dosimetric and radiobiological effects of the types of seed loss and migration common in prostate brachytherapy. METHODS This stu...

BACKGROUND Arbutus unedo is a valuable Mediterranean shrub as an ornamental plant as well as fruit tree. Fresh fruits of A. unedo are a good source of antioxidants, of vitamins C, E and carotenoids and also are characterized by the high content of mineral elements. MATERIALS AND METHODS The effects of gibberellic acid (GA3) and cold stratification (CS) on seed germination performance were inv...

Actually, the germplasm of Jatropha spp. is conserved as whole plants in field collections. Under this storage method, the genetic resources are exposed to disease, pest and natural hazards such as human error, drought and weather damage. Besides, field genebanks are costly to maintain and with important requirements of trained personnel. Thus, the development of efficient techniques to ensure ...

Pumpkin ( cucurbita maxima ) belongs to cucurbitaceae which include pumpkin, gourds, melons and squashes. They are characterized by their seed oil. Pumpkin plant has been grown since the earliest history of mankind 1 . ( Brucher – 1989 ). Pumpkin are grown around the world for variety of agricultural purposes, the seeds show anti helmintic, taenicide diuretic, cardio tonic, anti-inflammatory, a...

Corridors that connect patches of disjunct habitat may be promising tools for mediating the negative impacts of habitat fragmentation, but little is known about how corridors affect ecological interactions. In eight 12-ha experimental landscapes, we examined how corridors affect the impact of invertebrate, rodent, and avian seed predators on pokeweed, Phytolacca americana. Over 13 months in 200...

Priming is one of the most common methods of improving seed quality. The aim of this experiment was to study the effects of hydroand osmopriming on the germination, vigour and hydrolytic enzymes (α-amylase, β-glucosidase, exopeptidase and lipases) activity of zinnia (Zinnia elegans Jacq.) seeds. Seeds of three cultivars: Jowita, Kirke and Orys, and Z. elegans fl.pl., a mixture of cultivars (Mix...

Experiments were carried out to determine the potential of using the powder and essential oil from dried ground leaves of Cymbopogon citratus (lemon grass) to control storage deterioration and aflatoxin contamination of melon seeds (Colocynthis citrullus L.). Four mould species: Aspergillus flavus, A. niger, A. tamarii and Penicillium citrinum were inoculated in the form of conidia suspension (...

The protective effects of 5-aminolevulenic acid (ALA) on germination of Elymus nutans Griseb. seeds under cold stress were investigated. Seeds of E. nutans (Damxung, DX and Zhengdao, ZD) were pre-soaked with various concentrations (0, 0.1, 0.5, 1, 5, 10 and 25 mg l(-1)) of ALA for 24 h before germination under cold stress (5°C). Seeds of ZD were more susceptible to cold stress than DX seeds. Bo...

Research has been on-going on many plant materials, especially those discarded as waste, to exploit their nutritional and antinutritional properties. This is as a result of the United Nations’ millennium development goal to eradicate extreme poverty and hunger. Avocado (Persea americana Mill) seeds are often discarded after taking the pulp of the fruit. This study is aimed at evaluating the eff...
