DTI is a technique that identifies white matter tracts (WMT) non-invasively in healthy and non-healthy patients using diffusion measurements. Similar to visual pathways (VP), WMT are not visible with classical MRI or intra-operatively with microscope. DIT will help neurosurgeons to prevent destruction of the VP while removing lesions adjacent to this WMT. We have performed DTI on fifty patients...
Activation of the extracellular signal-regulated kinase1/2 (ERK1/2) signaling cascade mediates human multiple myeloma (MM) growth and survival triggered by cytokines and adhesion to bone marrow stromal cells (BMSCs). Here, we examined the effect of AZD6244 (ARRY-142886), a novel and specific MEK1/2 inhibitor, on human MM cell growth in the bone marrow (BM) milieu. AZD6244 blocks constitutive an...
Diffusion tensor imaging is a technique that enables physicians the portrayal of white matter tracts in vivo. We used this technique in order to depict the medial forebrain bundle (MFB) in 15 consecutive patients between 2012 and 2015. Men and women of all ages were included. There were six women and nine men. The mean age was 58.6 years (39-77). Nine patients were candidates for an eventual de...
The objective of this study was to investigate the effect of laser beam parameters on the mechanical and physical properties of cast commercially pure titanium. Dumbbell-shaped test specimens (ISO6871) were cast with ASTM grades 2 and 3 Ti. The cast surfaces were laser-treated with various laser emission parameters (current: 200, 220, and 240 A; spot diameter: 1.0, 1.6 mm; pulse duration: 10, 1...
The main aim of this study was to evaluate the effects of silicon (Si), ethanol (Et), ascorbic acid (AA) and citric acid (CA) on vase life of Narcissus tazetta L. cv. ‘Shahla’cut flowers. For this purpose, an experiment based on completely randomized design was conducted with Si (5, 10 and 20 mM), Et (2 and 4%), AA (100, 200 and 300 mg L-1), CA (100, 200 and 300 mg L-1) and control (distillated...
Cell-free synthesis of citrus exocortis viroid (CEV) in nuclei-rich preparations from infected Gynura aurantiaca was optimum at 18-24 degrees C. Incubation of reaction mixtures at higher temperatures (30-36 degrees C) resulted in an increase of CEV linear molecules and the recovery of incomplete or nicked newly synthesized RNA species. Although the Mg(2+) optimum (2.5-5 mM) for CEV synthesis wa...
Salinity is one of the factors limiting the growth and development of the plants that has a negative effect on morphological and physiological processes in plants and in order to reduce these adverse effects used to from growth regulators. In this study, the effect of hormone Salicylic acid (SA) at 3 levels (0, 1 and 2 mM) to relieve stress (NaCl Soluble at concentrations of 0, 50, 100 and 200 ...
Application of salicylic acid (SA) as a phytohormone has been increased due to resistance to stresses such as salt stress. To evaluate the effects of SA on growth and ornamental characteristics of Persian petunia under salt stress, a factorial experiment, based on completely randomized design, was conducted with 3 levels of SA (0, 1 and 2 mM) and 3 levels of NaCl (0, 150 and 300 mM) with 4 rep...
