There is increasing interest worldwide in how decision-making processes concerning controversial technological innovations can be improved by better integration of input from society at large. Aiming to gain knowledge on grapevine defence mechanisms against grapevine fanleaf virus (GFLV), a severe disease, scientists wanted to carry out a field trial of genetically modified grapevine rootstocks...

purpose: to determine the prevalence and determinants of age-related macular degeneration (amd) in a 40-64 year old iranian populationmethods: in a cross-sectional study, 6,311 people were randomly selected from shahroud. for all participants, visual acuity, refraction, slit-lamp examination and fundus photography were conducted under pupil dilation. results: results of this study are based on ...

background: cells have complex network of antioxidant enzymes that protect cells from induced damages by reactive oxygen species (ros). catalase and superoxide dismutase are known for their role as primary protection against oxidative stress. oxidative damage is an important risk factor in age-related macular degeneration disease (amd). for the first time in this study the impact of genetic pol...

Cell-to-cell movement of plant viruses occurs via plasmodesmata (PD), organelles that evolved to facilitate intercellular communications. Viral movement proteins (MP) modify PD to allow passage of the virus particles or nucleoproteins. This passage occurs via several distinct mechanisms one of which is MP-dependent formation of the tubules that traverse PD and provide a conduit for virion trans...

The ectoparasitic dagger nematode (Xiphinema index), vector of Grapevine fanleaf virus (GFLV), provokes gall formation and can cause severe damage to the root system of grapevines. Mycorrhiza formation by Glomus (syn. Rhizophagus) intraradices BEG141 reduced both gall formation on roots of the grapevine rootstock SO4 (Vitis berlandieri×V. riparia) and nematode number in the surrounding soil. Su...

The complete sequences of RNA1, RNA2 and satellite RNA have been determined for a South African isolate of Grapevine fanleaf virus (GFLV-SACH44). The two RNAs of GFLV-SACH44 are 7,341 nucleotides (nt) and 3,816 nt in length, respectively, and its satellite RNA (satRNA) is 1,104 nt in length, all excluding the poly(A) tail. Multiple sequence alignment of these sequences showed that GFLV-SACH44 R...

The putative 38 kDa movement protein (P38) gene, located on the RNA2 of grapevine fanleaf nepovirus (GFLV), was cloned in Escherichia coli and expressed as a fusion protein fused to six histidines (6HisP38). This protein was purified and used to produce a specific polyclonal antiserum from which immunoglobulins were isolated by immunoaffinity against the recombinant 6HisP38. Western immunoblot ...

Methamphetamine (meth) is a neurotoxic psychostimulant that increases monoamine oxidase (MAO)-dependent mitochondrial oxidant stress in axonal but not somatic compartments of substantia nigra pars compacta (SNc) and locus coeruleus (LC) neurons. Chronic meth administration results the degeneration SNc LC neurons male mice, MAO inhibition neuroprotective, suggesting deleterious effects chronic b...

In this paper, we consider a class of degenerate elliptic equations with arbitrary power degeneration. The issues about the existence, uniqueness, and smoothness solutions semiperiodic Dirichlet problem for degeneration are studied. two-sided estimates singular numbers (s-numbers) obtained. Note that show rate approximation found by finite-dimensional subspaces. Here, also obtain eigenvalues. W...
