The sessile lifestyle of plants requires them to cope with stresses in situ. Plants overcome abiotic stresses by altering structure/morphology, and in some extreme conditions, by compressing the life cycle to survive the stresses in the form of seeds. Genetic and molecular studies have uncovered complex regulatory processes that coordinate stress adaptation and tolerance in plants, which are in...

A new surface sensor probe comprising an angular array of Hall effect sensors has been developed for characterization of residual stresses in ferrous materials by means of stress‐induced magnetic anisotropy measurements. The sensor probe applies a radially spreading ac magnetic field to a test sample, and detects stray fields in different directions simultaneously to determine the principal str...

we have analyzed paraffin sections from 55 patients with histologically confirmed hodgkin’s disease (hd) for the presence of epstein-barr virus (ebv) markers using in situ hybridization to detect the ebv-encoded rnas (ebers) and immunohistochemistry to identify latent membrane protein-1 (lmp1) expression. tissue specimens from 55 cases of hodgkin’s disease included 22-mixed cellularity (mc), 27...

background:breast cancer remains the most common and second lethal cancer in females. her-2/neu is one of the most important amplified oncogene in breast cancer. the amplification of her-2 is correlated with decreased survival, metastasis, and early recurrence.  the amplification of her-2/neu gene and synthesis of the protein are reported in 10%-34% of breast cancer cases associated with tumor ...

background the incidence rate of gastric cancer in western countries has shown a remarkable decline in the recent years while it is still the most common cancer among males in iran. the proto-oncogene myc, located at 8q24.1, regulates almost 15% of human genes and is activated in 20% of all tumors. the amplification of myc and overexpression of its protein product are observed in 15 - 30% of ga...

in this study, doxycycline hyclate release behavior from in situ forming drug delivery systems investigated. these systems based on poly()lactide-co-glycolide)(50:50 dissolved in n-methyl-2-pyrrolidone that were evaluated in different concentrations. these systems are useful for local treatment of periodontal diseases. uv spectroscopy is used to determine drug concentration in release medium. a...

In studying of the in situ gravitational concentration process part feature for placer, the technological ability to transform the in situ massif placer structure is evident. The two main processes involved in altering the massif in situ have been examined and outlined in detail. The in situ disintegration of massif material results in a new massif gravitational stratification structure. Regula...

Recent estimates of the magnitude and orientation of lithospheric stresses are reviewed. Data come from a variety of sources including earthquake focal mechanisms, fault slip data, young volcanic dikes and feeders, in-situ stress measurements at depth, lithospheric flexure models, microstructure paleopiezometry, and consideration of constraints on maximum stress differences from laboratory-dete...
