Colorectal cancer (CRC) screening rates are low despite confirmed benefits. The authors investigated the use of natural language processing (NLP) to identify previous colonoscopy screening in electronic records from a random sample of 200 patients at least 50 years old. The authors developed algorithms to recognize temporal expressions and 'status indicators', such as 'patient refused', or 'tes...

A comparison of the performance of molecular descriptors of different types was conducted. The study was concentrated on determining which descriptors are included in the best linear multivariate regression models constructed for modeling various physicochemical properties (melting point, boiling point, refractive index, molar volume, and density) and biological activities (anaesthetic activity...

New molecular descriptors based on statistical descriptions of the local ionization potential, local electron affinity and the local polarizability at the surface of the molecule are proposed. The significance of these descriptors has been tested by calculating them for the Maybridge database in addition to our set of 26 descriptors described previously. The new descriptors show little correlat...

INTRODUCTION Smokers switching completely from combustible cigarettes to electronic cigarettes (e-cigarettes) are likely to reduce health risk, suggesting that e-cigarettes should be made appealing to adult smokers. However, uptake of e-cigarettes by nonsmoking teens would add risk without benefit and should be avoided. Although e-cigarette flavors may appeal to adult smokers, the concern is th...

We introduce a solid harmonic wavelet scattering representation, invariant to rigid motion and stable to deformations, for regression and classification of 2D and 3D signals. Solid harmonic wavelets are computed by multiplying solid harmonic functions with Gaussian windows dilated at different scales. Invariant scattering coefficients are obtained by cascading such wavelet transforms with the c...

first principles calculations were carried out for investigation the novel 7-hydroxycoumarinyl gallates derivatives in gas and liquid phases using density functional theory (dft) method. computational chemistry simulations were carried out to compare calculated quantum chemical parameters for gallates derivatives. all calculations were performed using dmol3 code which is based on dft. the doubl...

A rational design of economically cost-effective chemical libraries as well as successful data mining during a process of drug discovery employs a vast array of the molecular descriptors. Despite the huge importance of this area of the research there is still a need for the further development of the simple, intuitive, easily calculable, specific and size-invariant parameters of the molecular s...

Background: Healthy nutrition is vital for good health and well-being. Despite the important role of a healthy nutritional diet, recommendations for healthy eating remain elusive and are mainly based on general properties of nutrients. The present study proposes an improved characterization of the molecular characteristics of nutrients, which are important for biological functions and can be us...

Objectives: to review in the literature role and challenges of multidisciplinary team confronting Covid-19 collaborate improve health approaches. Methods: this is an integrative review, carried out from July August 2020. The data collection took place between years 2019 2020, electronic databases PubMed VHL (Virtual Health Library), through descriptors “multidisciplinary at Covid-19”, present D...
