Improved diagnosis of psoriasis, by new biomarkers, is required for evaluating the progression rate of the disease and the response to treatment. Haptoglobin (Hpt), a glycoprotein secreted by hepatocytes and other types of cells including keratinocytes, was found with glycan changes in psoriasis and other diseases. We previously reported that Hpt isolated from plasma of psoriatic patients is mo...

The influence of Mo alloying on the thermal stability of grain size, dislocation density and hardness of ultrafine-grained (UFG) Ni alloys was studied. The UFG microstructure in alloys with low (∼0.3 at.%) and high (∼5 at.%) Mo contents was achieved by high-pressure torsion (HPT) performed for 20 turns at room temperature. The thermal stability of the two alloys was studied by calorimetry. A Cu...

This paper identifies the mechanisms of phase and structural transformations during severe plastic deformation by shearing under pressure (high-pressure torsion) an Al-Zn-Mg-Fe-Ni-based aluminum alloy depending on different initial states material (an ingot after homogenizing annealing a rod produced radial-shear rolling). Scanning transmission electron microscopy are used to determine morpholo...

A Mg-8.2Gd-3.8Y-1.0Zn-0.4Zr (wt.%) alloy is processed by solution treatment and high pressure torsion (HPT) at room temperature to produce a nanostructured light material with hardness. The stability of this subsequently tested through isochronal annealing for 0.5 h 373 K 673 K. results reveal thermal that vastly superior conventional Mg-based alloys severe plastic deformation: the grain size r...

To analyze the local structure and/or chemical states of boron atoms in boron-doped diamond, which can be synthesized by the microwave plasma-assisted chemical vapor deposition method (CVD-B-diamond) and the temperature gradient method at high pressure and high temperature (HPT-B-diamond), we measured the soft X-ray emission spectra in the CK and BK regions of B-diamonds using synchrotron radia...

BACKGROUND Primary hyperparathyroidism (HPT) is a common cause of urolithiasis. Only a few data are available on stone composition and morphology in HPT patients. METHODS We compared the composition and morphology of stones from 264 HPT patients (143 males and 121 females) and 24 567 non-HPT stone formers (16 918 males and 7649 females) including a subgroup of 1356 patients with idiopathic hy...

introduction: hypoparathyroidism (hpt) is an irreversible but preventable disorder caused by an iron overload which can be considered a typical complication in patients with beta-thalassemia major. patients and method: parathyroid function was evaluated in 130 patients in qom, iran, who suffered from beta-thalassemia major. their serum ferritin levels were checked for monitoring of chelation th...
