Post-translational modifications are significant reactions that occur to proteins. One of these modifications is a non-enzymatic reaction between the oxo-group(s) of sugars and amino-group(s) of protein - glycation. This reaction plays an important role in the chronic complications of diabetes mellitus, or in the aging process of organisms, that is, it has an important role in the pathophysiolo...

A simple method for the simultaneous, rapid and sensitive determination of N-acylhomoserine lactone signaling molecules in bacterial isolates, without prior sample preconcentration and with minimal sample cleanup, is presented. The analysis relies on the combination of analyte preconcentration and separation on a single device: a relatively large sample volume (1-5 microL) is directly loaded on...

A continuous fixed bed study was carried out by using PAN-oxime-nano Fe2O3 as a sorbent for the removal of nitrate from aqueous solution. The effect of factors, such as flow rate (2, 5 and 7 mL/min) and bed depth (5, 10 and 15 cm) were studied. Data confirmed that the breakthrough curves were dependent on flow rate and bed depth. The adsoption capacities observed in diffent conditions of flow r...

We present a comparative study of thermomechanical properties of nano-polycrystalline nickel (nano-Ni) and micrometer-polycrystalline nickel (micron-Ni) by in situ high pressure-temperature (P-T) diffraction experiments. The yield strength of 2.35 GPa for the nano-Ni measured under high-pressure triaxial compression is more than three times that of the micron-Ni value. Contrary to tensile exper...

Both non-oxidized and oxidized mAb were diluted (1 to 9 ratio) with labeling buffer and incubated for multiple time points. The samples were then quenched with 4M guanidine, 200 mM citric acid (pH 2.7) at 0.5 °C and subject to online pepsin digest at 8 °C for three minutes at 50 μL/min flow rate in a fully automated manner using H/D-X PAL (LEAP Technologies). The digested peptides were injected...

Abstract This study focused on the use of a fix-bed column in removal amoxicillin from an aqueous solution by application silver nano-based adsorbents. The nanoparticle and nanocomposite were produced green synthetic approach. Column adsorption was performed at flow rate 5.88 mL/min, bed height (5.0–7.0 cm), concentration 20–40 mg/L. Adsorption data fitted to Thomas, Adams-Bohart, Yoon-Nelson m...

The objective of this study was to determine the efficacy separating X- and Y-sperm using nano-albumen (NA). material used in fresh semen Ongole Crossbreed bulls with progressive motility ≥ 70%. Treatments for top bottom fractions were T0 (BSA 5% : 10%) as a control, T1 (NA 2% 4%), T2 4% 6%), T3 6% 8%). Sexed evaluated characteristics kinematics, proportions sexed validated morphometric polymer...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...
