Relationships between the structural characteristic of synthetic chalcones and their antitumoral activity were studied. Treatment HepG2 cells for 24 h with 2’-hydroxychalcones resulted in apoptosis induction dose-dependent inhibition cell proliferation. The calculated reactivity indexes adiabatic electron affinities using DFT method including solvent effects, suggest a structure-activity relationship Chalcones structure cells. absence methoxy substituents B ring 2’-hydroxychalcones, showed...
In today’s highly competitive global market, winning requires near-perfect quality. Although most mature organizations operate their processes at very low defects per million opportunities, customers expect completely defect-free products. Therefore, the prompt detection of rare quality events has become an issue paramount importance and opportunity for manufacturing companies to move standards forward. This article presents learning process pattern recognition strategy a knowledge-based...
We investigate near-field energy transfer between chemically synthesized quantum dots (QDs) and two-dimensional semiconductors. fabricate devices in which electrostatically gated semiconducting monolayer molybdenum disulfide (MoS2) is placed atop a homogenous self-assembled layer of core-shell CdSSe QDs. demonstrate efficient non-radiative F\"orster resonant (FRET) from QDs into MoS2 prove that modest gate-induced variation the excitonic absorption lead to large (~500%) changes FRET rate....
Abstract Learning Analytics is a field that measures, analyses, and reports data about students their contexts to understand/improve learning the place in which it occurs. Educational institutions have different motivations use . Some want improve students' outcomes or optimize educational technology reduce dropout rate others. This concept presented with practical experiences been acquired validated by 16 institutions. Besides, an analysis of results, challenges, expectations was performed....
We demonstrate large area two-dimensional arrays of patterned nanoporous gold for use as easy-to-fabricate, cost-effective, and stable surface enhanced Raman scattering (SERS) templates. Using a simple one-step direct imprinting process, subwavelength (NPG) gratings are defined by densifying appropriate regions NPG film. Both the densified grating pattern shown to contribute SERS enhancement. The resulting substrates exhibit uniform enhancement factors at least 107 monolayer adsorbed...
Discussion of big data (BD) has been about data, software, and methods with an emphasis on retail personalization services products. Big also impacted engineering manufacturing resulted in better more efficient operations, improved quality, personalized A less apparent effect is that have changed problem solving: the problems we choose to solve, strategy seek, tools employ. This paper illustrates this point by showing how style thinking enabled development a new quality assurance philosophy...
Hepatocellular carcinoma (HCC) is one of the most commonly diagnosed cancers worldwide. Chemoprevention HCC can be achieved through use natural or synthetic compounds that reverse, suppress prevent development cancer progression. In this study, we investigated antiproliferative effects and mechanism action two compounds, 2,3,4′-trimethoxy-2′-hydroxy-chalcone (CH1) 3′-bromo-3,4-dimethoxy-chalcone (CH2), over human hepatoma cells (HepG2 Huh-7) cultured mouse hepatocytes (HepM). Cytotoxic were...
The detection of Jaguars, Panthera onca (Linnaeus, 1758), and Pumas, Puma concolor 1771), in the Sierra de las Minas Biosphere Reserve, northeastern Guatemala, represents a pivotal step understanding distributional range these apex predators country. Using camera traps, we documented 12 independent records one Jaguar, including remarkable presence Jaguars at elevations above 2000 m, which suggests new directions for ecological research high‑altitude conservation strategies. These...
Experimental tests were conducted with the lizard Liolaemus tenuis (Tropiduridae), to determine potential sources of pheromones used in its chemical communication, centered phenomenon self-recognition.During postreproductive season, feces both sexes and secretions precloacal pores (present only males) tested.Stimuli presented lizards spread on rocks, number tongue-flicks (TF) rocks was as a bioassay pheromone recognition.Feces contained involved self-recognition, since showed less TF...
Abstract 1,3‐Dipolar cycloadditions of C ‐carboxymethyl‐ N ‐arylnitrile imines with cyclic α,β‐unsaturated ketones various sizes have been studied. After cycloaddition, oxidative aromatization gives the ring‐fused pyrazoles. Computational studies and use topological analyses Fukui functions allows a theoretical description local reactivity that is in agreement experimentally observed regiochemistry.
This article reports the enhanced rate of surface-initiated polymerization (SIP) 5-(perfluoro-n-alkyl)norbornenes (NBFn) by combining two SIP techniques, namely atom-transfer (SI-ATRP) to grow a macroinitiator and ring-opening metathesis (SI-ROMP) produce final coating. approach promotes rapid growth dense partially fluorinated coatings that are highly hydrophobic oleophobic yield thicknesses from 4-12 μm. Specifically, limiting thickness pNBFn with different side chain lengths (n = 4, 6, 8,...
Flavonoids, which have many biological activities and been widely used in nature, can be artificially synthesized. However, regioselective cyclization of chalcones is difficult by chemical methods. In this study, we demonstrated that Aspergillus niger capable cyclizing to flavanones, affording a mimic plant biosynthetic processes. Chalcones 1–6 were biotransformated the modified 8–14 flavanones 15–27. The biotransformation showed enzymatic demethylation occurred during first days...
This manuscript describes the versatile fabrication and characterization of a novel composite membrane that consists porous alumina support, 100 nm thick nanoporous gold coating, selective poly(5-(perfluorohexyl)norbornene) (pNBF6) polymer can be grown exclusively from or throughout membrane. Integration three materials is achieved by means silane thiol chemistry, use surface-initiated ring-opening metathesis polymerization (SI-ROMP) to grow pNBF6. The SI-ROMP allows tailoring extent pNBF6...
Micromolding surface‐initiated polymerization enables the fabrication of polymer coatings that reproduce microscale surface topography superhydrophobic leaves onto solid supports. Here, surfaces from Trifolium repens and Aristolochia esperanzae are molded reproduced as a partially fluorinated coating through ring‐opening metathesis 5‐(perfluorooctyl)norbornene (NBF8). The have thicknesses exceeding 100 μm, which can be tailored by amount monomer added to mold. These robustly bound substrate,...
