Inflammatory bowel diseases (IBDs) are chronic relapsing inflammatory complications of the gastrointestinal tract (GIT) tract, which include Crohn’s disease (CD) and ulcerative colitis (UC) as prim...
Abstract The agglomeration mechanism of SiO2, TiO2, and ZnO nanoparticles by adding coarse fluid catalytic cracking (FCC) particles is studied. The core‐shell structure of agglomerates is revealed on the basis of experimental analyses. Nanoparticles can be fluidized by forming agglomerates of the core‐shell structure…
Abstract BACKGROUND Six corn starch inclusion complexes were synthesized using small nonpolar or weak polar aroma compounds (heptanolide, carvone and menthone) and small polar aroma compounds (linalool, heptanol and menthol). The objectives of this study were to (a) investigate the ability of corn starch to form inclu…
Abstract In order to investigate the hot deformation behaviors of as-extruded 7075 aluminum alloy, the isothermal compressive tests were conducted at the temperatures of 573, 623, 673 and 723 K and the strain rates of 0.01, 0.1, 1 and 10 s−1 on a Gleeble 1500 thermo-mechanical simulator. The flow behaviors showing com…
The current wide diffusion of bio-degradable plastic made up by starch-based polymeric composite has focused the attention on the allocation of bio-polymers for the direct recycling in composting processes. Actually, the acknowledged current methods to estimate the bio-degradability are mainly based on laboratory test…
Abstract Composite coating of Ni–Cu–P alloys containing TiN particles was prepared by electroless technique based on the excellent wear resistance of TiN and better anti‐corrosion property of electroless Ni–Cu–P alloys on carbon steel surfaces. Electrochemical method which uses Tafel polarization curves was carried ou…
In this paper, using the self-polymerization of norepinephrine (NE) and its favorable film-forming property, a simple and green preparation approach was developed to modify a PDMS channel for enantioseparation of chiral compounds. After the PDMS microchip was filled with NE solution, poly(norepinephrine) (PNE) film wa…
Small intestine submucosal (SIS) membrane used in this study is a decellularized, naturally occurring nanofibrous scaffold derived from a submucosal layer of porcine small intestine. It is predominantly composed of type I collagen fibers. Here we studied the bio-templated growth of hydroxylapatite (HAP) bone minerals…
Cancer is the leading cause of human death worldwide. Although many scientists work to fight this disease, multiple drug resistance is a predominant obstacle for effective cancer therapy. In drug-resistant MCF-7/ADR cells, the acidic organelles with lower pH value than normal one can cause the protonation of anthracyc…
Abstract BACKGROUND Hydrogen, as a clean and renewable energy source has become very attractive due to the deterioration of the global environment. In this way photocatalytic water‐splitting for H2 production using light energy in the presence of semiconductors capable of absorbing such irradiation has become a promis…
The structure and emulsification properties of octenyl succinic anhydride (OSA) starch hydrolyzed with hydrochloric acid (HCl) were studied by varying the HCl concentration through the range of 0.5–2.0 mol/L. The degree of substitution (DS), viscosity, thermal properties, and molecular weight (Mw) were obtained. A com…
The genomes uncoupled 4 (GUN4) protein is a nuclear-encoded, chloroplast-localized, porphyrin-binding protein implicated in retrograde signaling between the chloroplast and nucleus, although its exact role in this process is still unclear. Functionally, it enhances Mg-chelatase activity in the chlorophyll biosynthesis…
Abstract Esterification of acrylic acid with ethanol, catalyzed by sulfuric acid has been carried out in stirred batch reactor under atmospheric pressure. Different parameters such as effect of initial molar ratios of the reactants, effect of catalyst concentration, initial water and effect of temperature has been stu…
The treatment of glioblastoma (GBM) is a challenge for the biomedical research since cures remain elusive. Its current therapy, consisted on surgery, radiotherapy, and concomitant chemotherapy with temozolomide (TMZ), is often uneffective. Here, we proposed the use of zoledronic acid (ZOL) as a potential agent for the…
We study the human serum albumin (HSA) protein-CuO nanoparticle interaction to identify the specific binding site of protein with CuO nanoparticles by molecular docking and compared it with HSA-TiO2 nanoparticle interaction. The protein structural data that was obtained using Autodock 4.2. In case of CuO np-HSA intera…
AIMS: To isolate a novel strain that could degrade many kinds PAEs efficiently and investigate the DBP-degrading pathway in this strain. METHODS AND RESULTS: Based on its 16S rRNA gene sequence, the strain was identified as Rhizobium sp. This strain, named LMB-1, can also utilize phthalates, such as DEHP, DMP, DBP and…
Menisci are crucial structures in the knee joint as they play important functions in load transfer, maintaining joint stability and in homeostasis of articular cartilage. Unfortunately, ones of the most frequently occurring knee injuries are meniscal tears. Particularly tears in the avascular zone of the meniscus usua…
Exploring facile modifications on photoanode to suppress charge recombination at photoanode/electrolyte interfaces is an efficient way to improve the performance of quantum dot sensitized solar cells (QDSCs). Herein, a series of metal oxyhydroxide gels have been overcoated on CdSeTe QD sensitized photoanodes via a hyd…
This review paper presents an overview of heterogeneous selective ammoxidation and oxidative dehydrogenation (ODH) of light alkanes, particularly of ethane. The conversion of ethane to ethene is in great demand in the domestic and worldwide chemical industry. The review has been voluntarily restricted to metal oxide-t…
Microplastic pollution (particles <5mm) is a widespread marine threat and a trigger for biological effects, especially if ingested. The mussel Perna perna, an important food resource, was used as bioindicator to investigate the presence of microplastic pollution on Santos estuary, the most urbanized area of the coast…
