Conformational alterations of bovine hemoglobin (Hb) upon sequential addition of glyoxal over a range of 0-90% v/v were investigated. At 20% v/v glyoxal, molten globule (MG) state of Hb was observed by altered tryptophan fluorescence, high ANS binding, existence of intact heme, native-like secondary structure as depicted by far-UV circular dichroism (CD) and ATR-FTIR spectra as well as loss in ...

Graphene oxide (GO) nanoparticle is a high potential effective absorbent. Tetracycline (TC) is a broad-spectrum antibiotic produced, indicated for use against many bacterial infections. In the present research, a systematic study of the adsorption and release process of tetracycline on GO was performed by varying pH, sorption time and temperature. The results of our studies showed that tetracyc...

Double layers composed of Sn and Mg, each 0.8 μm thick, were fabricated on a hot-dip galvanized steel (8.4 μm) sheet using DC magnetron sputtering post-annealing processes. With an increase in temperature, the surface morphologies agglomerated with other. Additionally, Sn/Mg mixture sites, including intermetallic compound Mg2Sn, formed at 190 °C locally clustered 220 °C. In salt-spray test, cor...

Texture modification during sheet rolling appears differently in binary Mg-RE (rare-earth) or Mg-Ca alloy, compared to their ternary counterparts containing Zn. The differences texture development and the active deformation mechanisms under tensile loading were investigated alloys. These analyses are based on in-situ synchrotron experiments electron backscatter diffraction measurements reveal d...

The relation between the stored energy and the Taylor factor (TF) has been investigated using the SEM/EBSP analysis in an Al-Mg-Mn alloy sheet worked by the continuous cyclic bending (CCB). The analysis reveals that the stored energy is high for the high TF region, whereas a significant increase of the stored energy with the decrease of the Taylor factor appears in the vicinity of the minimum T...

BACKGROUND Renal accumulation of reactive carbonyl compounds (RCCs) has been linked to the progression of diabetic nephropathy. We previously demonstrated that carbonyl stress induces the formation of amino-carbonyl cross-links and sharply increases the content of β-sheet-rich structures, which is the seed of insoluble aggregates formation, and tea catechin (-)-epigallocatechin 3-gallate (EGCG)...

The main purpose of this research work is to study the forming limit and fracture behaviour AZ31 magnesium alloy, as well improve formability surface roughness parts formed using warm incremental sheet (ISF) process. For ISF process, Mg alloy sheets were used. Initially, Taguchi orthogonal L27 arrays used design experiments, a framed multi-objective optimization problem was solved grey-fuzzy me...

background : during the last 3 decades, there were increasing tendency towards angioplasty because of its benefits. but, this procedure has its acute problems like bleeding and formation of hematoma in the removal place of the sheet. based on researchers’ clinical experiences, patients need a time of 8-12 hours for bed rest after coronary angioplasty. recognizing desirable time for bed rest aft...
