background:   objective: it was investigated whether methylprednisolone had a favorable effect on osteoporotic bone tissue in oophorectomy induced osteoporotic rats whose endogenous adrenaline levels are suppressed with metyrosine.   materials and methods: bone mineral density, number of osteoblast-osteoclast, bone osteocalcin levels and alkaline phosphatase (alp) measurements were performed. o...

Despite of the recent progress, the knowledge about the underlying mechanisms behind tDCS is still limited. In order to gain insight in the sophisticated interplay of stimulation, volume conduction and resulting cortical current density distribution, we follow an effect-by-effect approach. We start our investigations with a homogenized isotropic three compartment (skin, skull, brain) head model...

Purpose Boron neutron capture therapy is a cellular-scale particle exploiting boron reactions in compounds distributed tumour cells. Its therapeutic effect depends on both the accumulation of cells and fluence. Autoradiography used to visualise micro-distribution compounds. Methods Here, we present an equation for relationship between concentration pit density solid-state nuclear track detector...

BACKGROUND We have examined the relationships between the measured properties of breast tissue and mammographic density and other risk factors for breast cancer, using breast tissue obtained at forensic autopsy and not selected for the presence of abnormalities. METHODS We used randomly selected tissue blocks taken from breast tissue slices obtained by s.c. mastectomy at the time of forensic ...

The effect of plasma lipoprotein fractions (large very-low-density lipoprotein, small very-low-density lipoprotein, intermediate-density lipoprotein, and low-density lipoprotein) on initiation of blood coagulation by supporting factor VII activation or by stimulating monocytes to express tissue factor was investigated in vitro. Endotoxin-free preparations of lipoprotein fractions did not induce...

Introduction: The use of a simple tissue analog material in the fabrication of medical computed tomography (CT) imaging phantoms has great potential to help researchers. The purpose of the present study is to develop new gel tissue-equivalent materials and determine whether their CT numbers and relative electron densities vary in CT images obtained by scans at different energie...

A subjective and incomplete list of interesting and unique features of the deconfinement phase transition is presented. Furthermore a formal similarity of the density matrix of the Aharonov-Bohm system and QCD is mentioned, as well.
