The pineapple, considered the third most important fruit in the world, is used as the main source of bromelain, an enzyme with anti-inflammatory activity and used for burns treatment.Nowadays, several researches show a possible application of this protein for cancer´s treatment.In this context, the purification of bio…
زمینه و هدف: داروهای بر پایه پلاتین با اتصال به هموگلوبین سبب آزاد شدن گروه هم از هموگلوبین شده، عملکرد هموگلوبین را مختل کرده و بدین ترتیب در بیمار تحت درمان ایجاد کم خونی می کند. هدف از تحقیق حاضر، بررسی اثرات جانبی اگزالی پالادیوم به عنوان یک داروی ضد سرطان جدید سنتزی، از طریق بر هم کنش با هموگلوبین و تخریب گروه هم…
Com a necessidade da utilização de fontes alternativas ao petróleo, as matérias-primas naturais adquiriram uma importância especial ao lado das matérias-primas minerais, pois podem ser utilizadas na produção de biopolímeros. Como exemplo disso tem-se a gelatina, um biopolímero produzido a partir da desnaturação do col…
In this paper are report the results of the synthesis and characterization of Mn3Ga thin films grown on Si2O/Si(001) substrates by sputtering technique, studying the thickness-dependent magnetic behavior of the film. The motivation for carrying out the reported work is the contribution in the application of this mater…
Since their discovery in naturally occurring compounds such as dynemicin and neocarzinostatin, enediyne-containing compounds have been investigated as potential chemotherapy drugs. When photoactivated, enediynes can undergo Bergman cyclization. The product of this reaction is a diradical capable of abstracting hydroge…
BACKGROUND: Previous animal study has shown that supplementation with silk amino acid hydrolysate (SAA) increases stamina in mice. The presented study was the first formal evaluation of the influence of SAA supplementation on parameters defining physiological fitness level in humans. METHODS: It was a randomized contr…
In this paper, we investigate the role of nonlocal interaction energy on nucleations of periodic solutions in a one-dimensional problem arising in smectic liquid crystals.
The processing and properties of a positive-tone, aqueous develop, epoxy crosslinked permanent dielectric based on a polynorbornene (PNB) backbone and bis(diazonaphthoquinone) (DNQ) photosensitive compound were investigated. The developing and cure properties of the films were studied as a function of cure temperature…
Diamond like carbon (DLC) films are deposited on glass substrates by using radio frequency plasma enhanced chemical vapour deposition technique with the variation of RF power. DLC films are deposited by using argon and acetylene plasma, at pressure 510-2 mbar for 60 minutes. Various properties like surface morphology,…
In this work, the interaction of Si, SiC and TiC with a Na2CO3-K2CO3 melt at 7500С on Ar atmosphere and in air was investigated. The optimal process for the fabrication of carbon fibers or nanotubes is interaction between silicon carbide and carbonate melts. It has been show that the modification of carbon materials d…
We previously found a very large NAD-dependent glutamate dehydrogenase with approximately 170 kDa subunit from Janthinobacterium lividum (Jl-GDH) and predicted that GDH reaction occurred in the central domain of the subunit. To gain further insights into the role of the central domain, several single point mutations w…
We have performed the theoretical study and 2D finite-difference time-domain-based computational modeling of middle-infrared radiation generation in the field of few-cycle laser pulse propagating in GaSe slab waveguide. The interaction of linearly polarized pulse with 1.98 um central wavelength, 22.44 fs duration, and…
Un-doped and Ti-doped ZnO films were deposited on microscopic glass substrates using spray pyrolysis technique systematically by controlling the deposition parameters. Zinc acetylacetonate was dissolved in ethanol and sprayed at substrate temperature of 400°C. For doped ZnO, titanyl acetylacetonate solution was added…
In this work, the dry sliding wear behaviour and friction characteristics of aluminium alloy Al6061 silicon carbide particulates (SiCp) of size 43 µm reinforced composites were evaluated through laboratory experiments. The content of SiCp in the alloy was varied from 5% to 35% in steps of 5% by weight. The metal matri…
In the title co-crystal, C25H32N4O2·C14H10O5, mol-ecules are connected into supra-molecular chains aligned along [102] by O-H⋯N hydrogen bonding. These aggregate into supra-molecular layers oriented parallel to (20-1) by C-H⋯O inter-actions. These layers then stack in an ABAB pattern along the c crystal direction to g…
Improvement in wear properties of rare earth Cerium base hypereutectic Aluminium-Silicon alloy with Manganese modification has been reported in this paper. Wear studies were carried out on cast samples of hypereutectic Aluminium-Silicon alloy (Al-Si) with rare earth Cerium oxide (CeO 2 ) and Manganese (Mn) modificatio…
To advance Thomson problem we generalize physical principles suggested by Caspar and Klug (CK) to model icosahedral capsids. Proposed simplest distortions of the CK spherical arrangements yield new-type trial structures very close to the lowest energy ones. In the region 600
Separation of the electrochemical product from an electrolyte can add challenges to the overall process. Use of a switchable electrolyte offers the possibility to reduce or eliminate these separation challenges while maintaining high conductivity. Reversible ionic liquids (RevILs) are a type of switchable solvent that…
Abstract A three-dimensional problem of the theory of elasticity for halfspace with multilayered coating with periodical structure is considered. The fundamental layer consists of two layers with different thicknesses and different mechanical properties. The coating is described by the homogenized model with microloca…
For at least fifteen years, concretions in the old clay pits near the village of Cicero in central New York State produced micro-sized specimens of eight common minerals in exquisite crystals. The many habits of calcite and goethite are particularly noteworthy. Material from this locality is familiar to micromounters,…
