Plant diseases influence the optical properties of plants in different ways. Depending on the host pathogen system and disease specific symptoms, different regions of the reflectance spectrum are affected, resulting in specific spectral signatures of diseased plants. The aim of this study was to examine the potential of hyperspectral imaging and non-imaging sensor systems for the detection, dif...

The consequences of treatment involving the use of a natural product and whole body vibration (WBV) exercise have been investigated. The aim of the present study was to evaluate the effects of the joint treatment with an aqueous extract of Chenopodium ambrosioides and WBV on physiological parameters in rats. Wistar rats (n=20) were divided equally into four groups: control group (CG), treated w...

BACKGROUND Inhibins are important regulators of the female reproductive system. Recently, two new inhibin subunits betaC and betaE have been described, although it is unclear if they are synthesized in normal human endometrium. METHODS Samples of human endometrium were obtained from 82 premenopausal, non-pregnant patients undergoing gynecological surgery for benign diseases. Endometrium sampl...

The genome of most Beet necrotic yellow vein virus (BNYVV) isolates is comprised of four RNAs. The ability of certain isolates to overcome Rz1-mediated resistance in sugar beet grown in the United States and Europe is associated with point mutations in the pathogenicity factor P25. When the virus is inoculated mechanically into sugar beet roots at high density, the ability depends on an alanine...

a total of 105 isolates of erysiphe betae from different regions of iran were investigated. for probable polymorphism of its-5.8s regions using pcr-based rflp, the mentioned fragments were amplified via pcr by its1 and its4 primers and subjected to 1.5% agarose gel electrophoresis. pcr products were digested by haeiii, alui, taqi, hindiii, cfoi, ecori, mspi, saci and rsai res and the digestion ...

Background: Bone defects caused by trauma, infection or tumor resection are common in orthopedic clinic and depending on the extent of the fracture; the vast majority require treatment with bone substitutes. Among the bone grafts employees, the autograft is defined as the gold standard, but with some limitations, principally related to morbidity at the site of its removal, with the need to sear...

To study the phylogenetic relationships between Erysiphe s. lat. and Microsphaera, the nucleotide sequences of internal transcribed spacers ofrDNA including 5.8S rDNA gene were determined for 23 taxa. The results showed that Erysiphe. section Erysiphe and Microsphaera are closely related and clustered together with strong bootstrap support (100%). All oftaxa belonging to this group produce coni...

Antifungal potential of aqueous extracts of forty plants of different families were tested against Fusarium oxysporum f.sp. ciceri causal agent of wilting of chick pea. Among forty plant species tested aqueous extract of Chenopodium ambrosioides has recorded significant antifungal activity against the test fungi. Solvent extracts viz. petroleum ether, benzene, chloroform, and methanol and ethan...
