Kidney stones, aggregates of microcrystals, most commonly contain calcium oxalate monohydrate (COM) as the primary constituent. The aggregation COM microcrystals and their attachment to epithelial cells are thought involve adhesion at crystal surfaces, mediated by anionic molecules or urinary macromolecules. Identification important functional group–crystal face adhesive combinations is crucial understanding stability strength attachments cell surfaces under flow in renal tubules kidney....
Kidney stones are crystal aggregates, most commonly containing calcium oxalate monohydrate (COM) microcrystals as the primary constituent. Macromolecules, specifically proteins rich with anionic side chains, thought to play an important role in regulation of COM growth, aggregation, and attachment cells, all key processes kidney stone formation. The microscopic events associated growth on {010}, {121̄}, {100} faces have been examined situ atomic force microscopy (AFM). Lattice images each...
Abstract Zeolite molecular sieves are widely used in gas separation and shape‐selective catalysis, but these applications often require discriminating differences as little 0.1 Å. Molecular sieving with such size selectivity demands zeolites highly tunable pore diameters adsorption properties, which technically challenging to prepare. Nevertheless, it is shown that a wide range of organic functional groups can be covalently functionalized onto the interior walls zeolites, MOR, LTL, FAU, MFI,...
Al 2 O 3 , widely used in the catalytic decomposition of fluorocarbons, is known to be rapidly deactivated owing its transformation AlF . Accordingly, this study, metal‐impregnated γ‐Al catalysts (M/γ‐Al ) were synthesized and their long‐term stabilities for HFC‐134a investigated under conditions 10,000 ppm air balance. Although Mg/γ‐Al demonstrated activities, significantly longer than those other catalysts, activity decreased, whereas that gradually decreased. exhibited smallest...
To investigate the anti-inflammatory effects of decursin and decursinol angelate-rich Angelica gigas Nakai (AGNE) on dextran sulfate sodium (DSS)-induced murine ulcerative colitis (UC). The therapeutic effect an AGNE was analyzed in a mouse model UC induced by DSS. Disease activity index values were measured clinical signs such as weight loss, stool consistency, rectal bleeding colon length. A histological analysis performed using hematoxylin eosin staining. Key inflammatory cytokines...
We investigated the cellular and molecular mechanisms mediating effects of Angelica gigas Nakai extract (AGNE) through mitogen-activated protein kinases (MAPKs)/NF-κB pathway using in vitro vivo atopic dermatitis (AD) models. examined AGNE on expression proinflammatory cytokines chemokines human mast cell line-1 (HMC-1) cells. Compound 48/80-induced pruritus 2,4-dinitrochlorobenzene- (DNCB-) induced AD-like skin lesion mouse models were also used to investigate antiallergic AGNE. reduced...
Abstract Monovalent ionic additives, Na + , K and NH impact on the morphology agglomeration of CaCO 3 crystals. As increasing additive concentration, regular shaped crystals such as rhombohedron spindle are changed to irregular one due inclusion into crystal structure. The is detected using ICP‐AES. partition coefficients estimated 9.74 × 10 –4 9.73×10 respectively amount in about 2×10 ppm. However, ions does not modify a structure calcite. Since 4 large radius, it included but shifts shape...
The effect of stoichiometric reaction conditions on CaCO3 crystallization was investigated using a Ca(OH)2−H2CO3 system in which the influence ionic byproducts effectively excluded. largest rhombohedron-like crystals were produced under stoichiometic (pH 7.8), corresponded closely to isoelectric point ≈ 8.2). When increasing excess Ca2+ species, individual crystal size rapidly reduced and shape gradually became spindle then needle. Meanwhile, with an CO32-, predominantly formed, although...
Single-phase three-component alkaline earth (BaSrMg)O crystals were prepared by a novel method, which show high performance in oxygen chemisorption.
A new systematic synthesis: an AIO reactor can materialize ultimate Ni nanocatalysts containing active nanoparticles (4.5 nm) with high loading (25 wt%), using a programmed sequence based on simple melt-infiltration and thermal treatment.
