BACKGROUND The aim of this study was to investigate the neuroprotective effects of sevoflurane after severe forebrain ischemic injury. We also examined the relationship between the duration of ischemia and neuronal cell death. METHODS Male Sprague-Dawley rats (300-380 g) were subjected to 6 (each n = 6) or 10 min (each n = 10) of near-complete forebrain ischemia while anesthetized with either...

this research was conducted under greenhouse conditions to evaluate the optimum combination of irrigation and fertilizer levels to attain the best yield and quality of tomato crop. the experiment was conducted by using a split-plot design with three replicates. irrigation levels were applied to the main plots and fertilizer levels to the sub-plots. for each experimental unit, the irrigation lev...

Background: Artemisia dracunculus L. belongs to the Anthemideae tribe of Asteraceae family. This plant has been used in traditional folk medicine. Also, it's anti-bacterial, anti-fungal, antioxidant, anti-inflammatory and hepatoprotective activity has been proved. Objective: The purpose of this study was to evaluate the antioxidant activity of leaves and inflorescence of A. dracunculus and als...

background: improving vaccine potency in the induction of a strong cell-mediated cytotoxicity can enhance the efficacy of vaccines. necrotic cells and the supernatant of necrotic tumor cells are attractive adjuvants, on account of their ability to recruit antigen-presenting cells to the site of antigen synthesis as well as its ability to stimulate the maturation of dendritic cells. objective: t...

The bacterium Dickeya dadantii is responsible of important economic losses in crop yield worldwide. In melon leaves, D. dadantii produced multiple necrotic spots surrounded by a chlorotic halo, followed by necrosis of the whole infiltrated area and chlorosis in the surrounding tissues. The extent of these symptoms, as well as the day of appearance, was dose-dependent. Several imaging techniques...

Effects of de®ciencies in N, P, K, Ca, Mg, B and Fe on leaf development, visual symptoms and shoot±root dry weight ratio were studied in Spathiphyllum `Sensation' grown hydroponically. Leaf nutrient contents of treated plants were analyzed to con®rm suspected de®ciencies. Leaf number, leaf area and chlorophyll content were all signi®cantly reduced in the nitrogen-de®cient plants similar to plan...

Surveys of yellowing viruses in plastic tunnels and in open field crops of melon (Cucumis melo cultivar catalupo), oriental melon (C. melo cultivar oriental melon), and cucumber (C. sativus) were carried out in two melon-growing areas in 2014, Korea. Severe yellowing symptoms on older leaves of melon and chlorotic spots on younger leaves of melon were observed in the plastic tunnels. The sympto...

Resistance to virus infections in higher vertebrates is mediated in part through catalysis of RNA decay by the, interferon-regulated 2-5A system. A functional 2-5A system requires two enzymes, a 2-5A synthetase that produces 5'-phosphorylated, 2',5'-linked oligoadenylates (2-5A) in response to double-stranded RNA, and the 2-5A-dependent RNase L. We have coexpressed these human enzymes in transg...
