Early prediction of diabetic type 2 based on fuzzy technique

Intelligent analysis of present lifestyle may help to understand the development of the chronic diseases and the relationship of these diseases together. It is possible to reduce or prevent the development of these diseases. In this work, a novel intelligent method is introduced and applied for early detection of type 2 diabetic. Intelligent analysis depends mainly on evaluation life-threatening conditions (obesity, hypertension, smoking status, alcohol drinking status and low level of physical activities) to extract knowledge from linguistic variablesand design a new cognitive tool to assist in the prediction process.This method consists from three stages: in the first stage, data was collected from 100 healthy volunteers, which includes evaluations of life-threatening conditions. The second stage is implementation of fuzzy model for early prediction of type 2 diabetes. Predicted blood glucose values of proposal technique were compared with average fasting blood glucose values based on analysis of Bland-Altman plot. Furthermore, fuzzy system model presents superior results (accuracy = 81%, precision = 0.57% and recall = 0.83%).

A novel Bi-based crystalline molecular material: fluorescence response of the high efficient detection and recognition of the organic amines and white luminescence tuning

A novel Bi-based crystalline molecular materials Bi(C2O4)(3)(NMP)(2) (Bi-NMP) have successfully synthesized by the reaction of Bi(NO3)(3)center dot 5H(2)O, N-Methylpyrrolidone (NMP) in the solution of methyl alcohol. Structural analysis indicates that the Bi-NMP shows a novel 2D planar structure. The luminescent behavior for the Bi-NMP has been investigated at room temperature. The results have shown that Bi-NMP can be used as a chemical sensor for multifunctional testing such as aliphatic amines and aromatic amines detection, because of its strong fluorescence properties. When detecting cyclohexylamine (CHA), the K was 2.5 x 10(5) M–(1),( )and the detection limit was 0.99 mu M. When detecting m-phenylenediamine(MPD), the K-sv was 5.5 x 10(3) M-1, and the detection limit was 45.7 mu M. When detecting o-phenylenediamine (OPD), the K was 5.4 x 10(3) M-1, and the detection limit of Bi-NMP was calculated to be 49.9 mu M. In particular, for o-phenylenediamine (OPD), Bi-NMP has a unique switching effect. Therefore, Bi-NMP has not only a detection function but also a recognition function for o-phenylenediamine (OPD), m-phenylenediamine (MPD) and p-phenylenediamine (PPD). In addition, white-light emission is achieved through a reasonable tuning proportion by mixing Sm-3(+) in Bi-NMP. (C) 2020 Elsevier B.V. All rights reserved.

trans-Cinnamaldehyde-doped quadripartite biopolymeric films: Rheological behavior of film-forming solutions and biofunctional performance of films

Biofunctional quadripartite films were developed by adding trans-Cinnamaldehyde (CIN) (0.4, 0.8, and 1.6% w/v) into chitosan (CH)/poly(vinyl alcohol) (PVA)/fish gelatin (FG) matrices. Rheological data revealed that all solutions exhibited shear-thinning and typical entangle polymers solutions behavior. Mechanical results showed that the incorporation of CIN caused a significant increase (p < 0.05) in tensile strength, while a significant decrease was observed in elongation-at-break. With increasing CIN content, the WVP of the films, which were in the range of 0.785-0.995 g mm/kPa h m(2), increased to some extent, whereas the water solubility and water absorption were reduced up to 47 and 87%, respectively. Moreover, water contact angle analysis showed that the inclusion of CIN made the quadripartite film more hydrophobic, in which the highest value achieved was 86.6 +/- 0.75 degrees at theta(t=10). ATR/FT-IR spectroscopy demonstrated the formation of Schiff-base and intermolecular hydrogen bonds between components' functional groups, which enhanced the quadripartite films' thermal stability and mechanical properties. X-ray diffraction analysis suggested compatibility among the components, and changes of the surface of the films were confirmed by SEM and AFM analyses. Likewise, the antimicrobial activity of the CIN-loaded films were proved against Staphylococcus aureus, Listeria monocytogenes, Salmonella enteritidis, and Escherichia coli. The quadripartite films exhibited in vitro DPPH radical scavenging activity (similar to 35.8%) and ferric reducing power at the maximum CIN testing concentration. The findings of this study proved that CIN-doped films could be used as promising inner functional packaging for food products.

Surface structures consisting of chromatin fibers in isolated barley (Hordeum vulgare) chromosomes revealed by helium ion microscopy

The chromosome compaction of chromatin fibers results in the formation of the nucleosome, which consists of a DNA unit coiled around a core of histone molecules associated with linker histone. The compaction of chromatin fibers has been a topic of controversy since the discovery of chromosomes in the 19th century. Although chromatin fibers were first identified using electron microscopy, the chromatin fibers on the surface of chromosome structures in plants remain unclear due to shrinking and breaking caused by prior chromosome isolation or preparation with alcohol and acid fixation, and critical point drying occurred into dehydration and denatured chromosomal proteins. This study aimed to develop a high-quality procedure for the isolation and preparation of plant chromosomes, maintaining the native chromosome structure, to elucidate the organization of chromatin fibers on the surface of plant chromosomes by electron microscopy. A simple technique to isolate intact barley (Hordeum vulgare) chromosomes with a high yield was developed, allowing chromosomes to be observed with a high-resolution scanning ion microscopy and helium ion microscopy (HIM) imaging technology, based on a scanning helium ion beam. HIM images from the surface chromatin fibers were analyzed to determine the size and alignment of the chromatin fibers. The unit size of the chromatin fibers was 11.6 +/- 3.5 nm and was closely aligned to the chromatin network model. Our findings indicate that compacting the surface structure of barley via a chromatin network and observation via HIM are powerful tools for investigating the structure of chromatin.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 4740-78-7 is helpful to your research. Safety of 1,3-Dioxan-5-ol.

Multidimensional elements of impulsivity as shared and unique risk factors for food addiction and alcohol misuse

Food addiction (FA) and alcohol misuse tend to co-occur, which suggests shared factors in the etiology and persistence of these health behaviors. One shared factor that has been linked to both is impulsivity, a multidimensional construct reflecting multiple facets of self-regulatory capacity. However, co-occurrence also raises issues of possible confounding if both domains are not considered concurrently, and the intersection between FA, alcohol misuse, and impulsivity has not been well characterized empirically. Therefore, the current study examined the intersection of FA, alcohol consequences, and multiple indicators of impulsivity. Participants were emerging adults reporting regular heavy episodic drinking recruited from Hamilton, Ontario (N = 730; ages 19.5-23). Participants completed measures of FA, alcohol problems, impulsive personality traits (i.e., Barratt Impulsiveness Scales, UPPS-P Impulsive Behavior Scales), impulsive choice (i.e., delay discounting), impulsive action (i.e., Go/NoGo task). Findings revealed a significant association between FA and alcohol-related consequences and both shared similar associations with specific impulsive personality traits (Positive and Negative Urgency, Lack of Premeditation, Motor and Attentional Impulsivity). However, alcohol-related consequences were uniquely associated with other impulsive personality traits (Lack of Perseverance, Sensation Seeking, Non-planning impulsivity) and impulsive choice, and FA was uniquely associated with impulsive action. Beyond alcohol-related consequences, FA was associated with additional variance in measures of impulsive personality traits (Positive and Negative Urgency, Lack of Premeditation, Motor Impulsivity, and Attentional Impulsivity) and impulsive action, but not impulsive choice. Overall, the current study reveals several common self-regulatory processes associated with both adverse drinking consequences and FA, and that the risk of inadvertent confounding appears to be limited.

Integrated approaches to testing and assessment as a tool for the hazard assessment and risk characterization of cosmetic preservatives

The safety assessment of cosmetic products is based on the safety of the ingredients, which requires information on chemical structures, toxicological profiles, and exposure data. Approximately 6% of the population is sensitized to cosmetic ingredients, especially preservatives and fragrances. In this context, the aim of this study was to perform a hazard assessment and risk characterization of benzalkonium chloride (BAC), benzyl alcohol (BA), caprylyl glycol (CG), ethylhexylglycerin (EG), chlorphenesin (CP), dehydroacetic acid (DHA), sodium dehydroacetate (SDH), iodopropynyl butylcarbamate (IPBC), methylchloroisothiazolinone and methylisothiazolinone (MCI/MIT), methylisothiazolinone (MIT), phenoxyethanol (PE), potassium sorbate (PS), and sodium benzoate (SB). Considering the integrated approaches to testing and assessment (IATA) and weight of evidence (WoE) as a decision tree, based on published safety reports. The hazard assessment was composed of a toxicological matrix correlating the toxicity level, defined as low (L), moderate (M), or high (H) and local or systemic exposure, considering the endpoints of skin sensitization, skin irritation, eye irritation, phototoxicity, acute oral toxicity, carcinogenicity, mutagenicity/genotoxicity, and endocrine activity. In a risk assessment approach, most preservatives had a margin of safety (MoS) above 100, except for DHA, SDH, and EG, considering the worst-case scenario (100% dermal absorption). However, isolated data do not set up a safety assessment. It is necessary to carry out a rational risk characterization considering hazard and exposure assessment to estimate the level of risk of an adverse health outcome, based on the concentration in a product, frequency of use, type of product, route of exposure, body surface location, and target population.

ultrasonography of kidney and spleen in clinically healthy llamas and alpacas

Background: The ultrasonographic examination technique is a well-established, non-invasive diagnostic tool for diverse conditions in humans and different animal species. The purpose of our study was to describe ultrasonographic localisation, sonographic appearance and dimensions of the kidneys and spleen of clinically healthy llamas and alpacas. Differences between llamas and alpacas and the influence of sex and ages were investigated. Results of this study may aid veterinarians performing ultrasonography in diseased animals and the technique can be used for routine protocol screening. Results: Ultrasonography was performed in 135 clinically healthy, non-sedated llamas and alpacas. Screening was performed with a 6.6 MHz curve linear transducer with only alcohol as contact medium between the probe and unclipped skin. The kidneys could be imaged from the paralumbar region. The right kidney only was visualized when scanning from the right and the left kidney only from the left. While the left kidney appeared in sagittal view as an oval shape in most llamas and alpacas, in one third of animals the left kidney had a triangular shape. The L-shaped base of the spleen, with its homogeneous, echoic pattern, could be seen craniolateral to the left kidney. Anechoic areas displaying vessels inside the spleen and a thin echoic capsule surrounding the splenic tissue could be differentiated. While sonographic appearances of the examined organs showed no differences between llamas and alpacas, selected dimensions of both of kidney and spleen showed significant differences between species. In terms of age and sex, significant differences in respect of kidney size could be found only in alpacas. Sex seemed to have no influence on kidney and spleen sizes in llamas. Conclusions: The present study provides species-specific information on ultrasonographic appearance and reference values for kidney and spleen dimensions of clinically healthy llamas and alpacas. Results show differences in organ sizes between llamas and alpacas and in alpacas of different sex and age. The results of this study can be used as references for veterinarians performing ultrasound examinations in diseased animals.

Fabrication of carboxymethyl chitosan/poly(epsilon-caprolactone)/doxorubicin/nickel ferrite core-shell fibers for controlled release of doxorubicin against breast cancer

The coaxial electrospinning for producing core-shell nanofibers due to control the release profile of drug by the shell layer has been developed. N-carboxymethyl chitosan (CMC)-polyvinyl alcohol (core)/poly(epsilon-caprolactone) (PCL) (shell) nanofibers were produced via coaxial electrospinning. Doxorubicin (DOX) and nickel ferrite nanoparticles were incorporated into the nanofibers for controlled release of DOX against MCF-7 breast cancer. The minimum CMC/PCL fiber diameter was found to be 300 nm by optimizing of three variables including voltage to distance ratio (1.5-2.5 kV/cm), CMC concentration (4-6 wt.%) and PCL concentration (8-12 wt.%). The synthesized core-shell fibers were characterized using FTIR, XRD, SEM, and TEM analysis. The extended release and controlled release of DOX from core-shell nanofibers were achieved under physiological pH without external magnetic field (EMF) and acidic pH with EMF during 25 and 7 days, respectively. The maximum cytotoxicity of MCF-7 breast cancer cells was about 83 % using CMC/PCL/nickel ferrite 10 % nanofibers and EMF.

Chemoselective hydrogenation of alpha,beta-unsaturated carbonyl compounds using a recyclable Ru catalyst embedded on a bisphosphine based POP

Selective hydrogenation of the carbonyl functional group of alpha,beta-unsaturated carbonyl compounds affords industrially important allylic alcohols. However, achieving the selective reduction of the carbonyl group in the presence of the activated olefinic group is challenging. Therefore, the development of a highly chemoselective, efficient, and recyclable catalyst for this transformation is greatly desirable from the industrial and environmental viewpoints. In this study, a Ru-immobilized bisphosphine-based porous organic polymer (Ru@PP-POP) was used as an efficient heterogeneous catalyst for chemoselective hydrogenation of cinnamaldehyde (CAL) to cinnamyl alcohol with high chemoselectivity (98%) and excellent recyclability. To the best of our knowledge, the catalyst, Ru@PP-POP showed a high turnover number (970) and a high turnover frequency (240h(1)) which is the best activity obtained using a phosphine based heterogeneous Ru-catalyst in this transformation.

Photo image processing analysis of electron beam irradiation on a new liquid scintillator based on alcohol

Liquid scintillator is widely used in various fields. This paper proposes a new base material, a mixture of alcohol and water for liquid scintillator and introduces photo image analysis to investigate electron beam irradiation on the new alcohol-based liquid scintillator. A possibility of using alcohol as a new detection solution in particle detector is briefly described. Alcohol has good solubility for fluor, is biodegradable and has low toxicity. The development of an alcohol-based liquid scintillator was investigated and some physical and optical properties of the alcohol-based liquid scintillator were measured. The energy exchange process that the absorption spectrum overlaps with the emission spectrum was seen in our alcohol-based liquid scintillator. To date, there have been no R&D studies elsewhere for use of alcohol-based liquid scintillator in particle detectors. As an application, we introduce a new measurement technique where range measurements were achieved after irradiating an alcohol-based liquid scintillator with electron beam energies of 6-12 MeV. By analyzing the range images taken by digital camera, or even mobile phone camera, it was possible to find out the fluor component dissolved in the alcohol-based liquid scintillator. This method has sufficient potential as it enables us to estimate wavelengths in the visible region without using an expensive spectrophotometer. These results can be used in medical imaging applications for the treatment of tumors or cancers where irradiation by electron beams takes place. Furthermore, alcohol-based LS could be used in future, next generation particle detectors.
