The water relations of Picea abies in a healthy stand with green trees only and a declining stand with trees showing different stages of needle yellowing were investigated in northern Bavaria. The present study is based on observations of trees differing in their nutritional status but apparently green on both sites in order to identify changes in the response pattern which might be caused by a...

The knowledge of variations in the superficial veins is of clinical importance for the anatomist, radiologists, clinical practitioners and surgeons in order to plan about the operative procedures. Usually cephalic vein drains into the axillary vein. In this case report study the left cephalic vein communicates with the left external jugular vein and made a common trunk at th...

in order to examine the effects of essential oils and silver nanoparticles as anantimicrobial preservative in the solutions of alstroemeri cv. sukari cut flowers, anexperiment was conducted with 11 treatments and 3 replications in a completelyrandomized design. in this study, we used essences of carvacrol, thymol and zataria oilwithconcentrations of 50 and 100 mg l-1 and silver nanoparticles wi...

recently multiple studies have shown that elevated homocysteine levels may be associated with ophthalmic vascular disease. to investigate the role of high plasma levels of homocysteine in the patients with retinal vein occlusion, 21 patients with retinal vein occlusion (rvo) and 20 age and sex matched controls without rvo were included in this retrospective case–control study. information regar...

Next-generation sequencing (NGS) has been applied to plant virology since 2009. NGS provides highly efficient, rapid, low cost DNA, or RNA high-throughput sequencing of the genomes of plant viruses and viroids and of the specific small RNAs generated during the infection process. These small RNAs, which cover frequently the whole genome of the infectious agent, are 21-24 nt long and are known a...

Phylogenetic analysis of a 500 bp fragment of the secA gene has been performed on 35 phytoplasma isolates representing 10 of the 16S rDNA groups. The lineages obtained coincide with those delineated by 16S rDNA phylogenetic analysis but much greater genetic variability was evident. In addition, phylogenetic analysis based on part of the 23S rDNA gene combined with T-RFLP (terminal restriction f...
