Ethylene production was determined in excised tomato (Lycopersicon esculentum) root cultures of Meloidogyne javanica susceptible and resistant cultivars infected with M. javanica. Uninfected cultivars produced very low amounts of ethylene. Relatively high amounts of ethylene were produced by the infected susceptible cultivars. Peak production of 1.6 n moles * g root(1) * h(1) occurred between 9...

The aim of this study is to evaluate the microleakage a self-adhesive cement recently marketed Rely X U100 (3M ESPE). Thirty roots of bovine teeth with 14 mm long were restored with self-adhesive cement and Glassix fiber post DC3 (FGM). Roots were randomly divided into three groups (n=10) according to the technique of placement of the cementing agent: G1 - Centrix syringe; G2 - Lentulo drill an...

Hydroxyurea (HU) at concentrations of 10 or 20 mg/liter was included in a medium on which excised tomato roots infected with the root-knot nematode Meloidogyne javanica were grown. In the HU, treated roots, giant cells were small and contained large vacuoles. Giant cell nuclei were amoeboidal with relatively small nucleoli in treated roots, compared with giant cells of nontreated galls. In trea...

Supplemental Experimental Procedures Confocal UV Laser Scanning Microscopy of Filipin-Sterol Fluorescence Dot-Blot Detection of Filipin-Sterol Fluorescence Analysis of Arabidopsis roots was performed by employing a Nikon Sterols (Sigma) and 4-cholesten-3-one (Sigma) in chloroform at 20 Diaphot 300 inverted microscope, connected to a Nikon RCM 8000 mM were spotted onto Transblot nitrocellulose m...

Background S. munja roots have been used in ethno medicines for the treatment of different ailments. Despite its beneficial uses no studies on its toxicity potential have been reported. Objective The study was designed to evaluate acute toxic potential of aqueous ethanolic extract of S. munja roots according to OECD TG No. 425. Material and methods Female mice were divided into two groups (...

Infected tissues of roots and leaves of various grasses as well as soil around their rhizosphere were sampled from Fars, Golestan, Isfahan, Khorasan Shomali, Khorasan Razavi, Mazandaran and Semnan provinces (Iran). Based on morphological characteristics and available keys, four species of Bipolaris including B. austreliensis, B. indica, B. micropus and B. spicifera, four species of Curvularia i...

Objective. To characterize the fungal pathogenic complex of root zone cultivated soybean plants grown on sod-medium podzolic soil, to identify most harmful pathogens diseases. Methods. Phytopathogenic micromycetes were isolated from affected plants. For this, segments plant material (roots, seeds, leaf blade) (3–5 mm) thoroughly washed for 15 min under running water, their surface was sterilize...

Assays of specific activities and electrophoretic separations of multiple forms of 6-phosphogluconate dehydrogenase and peroxidase in cotton resistant and susceptible to Meloidogyne incognita were conducted 6 days after inoculation. Specific activities were greater in infected than in uninfected roots and also were greater in the resistant cultivar, 'Clevewilt 6-3-5,' than in the susceptible cu...

Adhesion sites on grass roots for Klebsiella strains carrying type 3 or type 1 fimbriae or both were determined. Adhesion of the strains to the roots of Poa pratensis and Festuca rubra was highly localized; the bacteria adhered strongly to root hairs and with a markedly lower efficiency to the surface of the zone of elongation and to the root cap mucilage. No adhesion to the epidermal cells bet...

BACKGROUND/AIMS Longer exposure to hepatitis C (HCV) or B virus (HBV) and the increased use of hepatitis treatment might have an impact on liver-related deaths in patients co-infected with the Human Immunodeficiency Virus (HIV). We describe the proportion of liver-related deaths among HIV-infected patients in 2005 compared with 2000. METHODS In a nationwide survey (341 hospital departments in...
