Evaluation of total polyphenol content of wines by means of voltammetric techniques: Cyclic voltammetry vs differential pulse voltammetry

Taking advantage of the low oxidation potential of polyphenolic compounds, voltammetric techniques, such as cyclic voltammetry (CV) and differential pulse voltammetry (DPV) are used rather indiscriminately. In this work, we report Total Polyphenols results (TPP) obtained by these two techniques from a set of nine samples of red and Tawny Port wine. The CV and DPV voltammograms display significant correlations with the physical-chemical parameters used to characterize red and Tawny Port wines, particularly with polyphenols. Although data obtained from CV and DPV for a single polyphenol are directly proportional, important deviations are found between voltammetric results from wines. Results from CV tend to be larger than those from DPV. This difference, that can reach 50% of the TPP value, was related to the presence of total sulphur dioxide. In view of the present study, the polyphenol quantification in wines should be performed by DPV to minimize the interference of SO2.This work received financial support from the Foundation for Science and Technology (FCT, Portugal), through projects UID/QUI/00686/2013 and UID/QUI/00686/2016 (CQUM)

Motor Programs as Indicators of Penalty Direction in Soccer

Introduction: Many football games are decided on penalties and usually in championship final games. When seeking to anticipate movements, differences in amplitude can harm players because the informational movement appears to be spread "globally" throughout the action and should be coded at several levels. Thus, it would be interesting to analyze the entire period of the kick, since the player begins his run to approach the ball to recognize the motor patterns used in the kick that identify his direction. Objective: The objective of this study is to identify patterns of behavior in penalty kicks that may indicate the direction of their action / kick and in my moment they appear. Methodology: The sample consisted of 21 subjects hitting a penalty kick, 18 males and 3 females with an average age of 22.18 ± 2.44 years and two goalkeepers with college football experience. The tests consisted of a battery of two penalty kicks for each subject in order to score. The kicks were recorded by a video camera with a front view of the goal goal and the back of the batter. The kick phases were divided into the starting leg position; first step leg; angle of the elbow in relation to the body seen from behind; angle of the elbow in relation to the displacement line seen from above; direction of the tip of the supporting foot and position on the goal where the kick was. Each kick was preceded by a start signal. The data were analyzed from the registration of each variable and the position of the goal in which the ball was kicked, considering it in three sectors: left, right and central. Results: The main results indicated that the variable “Leg of the first step” had 81% of the kicks associated with the direction of the goal; 52.4% of second kicks had repeated the pattern of behavior and 84.6% had repeated the pattern of behavior regardless of the goal position. The variable “Elbow angle in relation to the body seen from behind” had 81.8% repeated behavior pattern regardless of the goal position and the variable “Elbow angle in relation to the displacement line seen from above” had 81% association with the sector of the goal in which the ball was kicked; 52.4% of second kicks had repeated the pattern of behavior and 91.7% had repeated the pattern of behavior regardless of the goal position. Conclusions: The main conclusions indicate that it is possible to relate the kick location with the batter\u27s body information; the start of the race seems to indicate that there is a prior intention of movement programs; the decision of where to hit the penalty appears to be made before contact with the ball and more closely to the placement of the support foot and with this relationship, the size of the goal to be defended by the goalkeeper could be reduced, increasing the possibility of defense

CARACTERIZAÇÃO DE MORBIDADES AUTORREFERIDAS ENTRE IDOSOS RESIDENTES EM ZONA RURAL BRASILEIRA

Trata-se de uma pesquisa de campo que objetivou identificar o perfil social, de autonomia e de comorbidades autorreferidas dos idosos da área rural, em Santa Luzia do Itanhy/Sergipe. Realizou-se um estudo quantitativo de abordagem descritiva, a amostra populacional foi definida em 103 idosos, no entanto, apenas 76 aceitaram participar da pesquisa. Antes da entrevista, foi realizada a leitura e esclarecimentos sobre a pesquisa a cada um dos idosos participantes, e após a assinatura do Termo de Consentimento Livre e Esclarecido (TCLE), ocorreram as entrevistas. Após análise dos dados sociodemográficos dos entrevistados, identificou-se que a idade média foi de 60 anos e a maioria referiram etnia parda (83%). Em relação à escolaridade 70% são analfabetos. Entre as ocupações exercida a mais prevalente foi a de agricultor 17%. Sobre o estado civil 50% são casados. Nos fatores relacionados ao risco de comorbidades 71% dizem ser sedentários. Sobre as morbidades autorreferidas 62% informaram hipertensão. Verificou-se que 64% dos idosos praticam automedicação. Quanto a autonomia, observou-se que 92% realizam suas atividades diárias de vida. Conclui-se que a dificuldade de acesso aos serviços de saúde, pode ser um fator que impacte na assistência desses idosos, entende-se que políticas de saúde voltadas ao envelhecimento carecem de adequações socioculturais, no sentido que atenderem aos idosos que residem na zona rural de forma equânime

Copper Bis(oxazoline) Encapsulated in Zeolites and Its Application as Heterogeneous Catalysts for the Cyclopropanation of Styrene

A copper C(2)-symmetric bis(oxazoline), CuBox, was introduced in two forms of commercial Y zeolite: a sodium form (NaY) and an ultrastable form (NaUSY). CuBox was introduced by first partially exchanging the sodium cations of both zeolites for copper and then by refluxing the obtained materials with a solution of bis(oxazoline) (Box). Two different loadings were prepared for each form of zeolite. The materials were characterized by copper ICP-AES, elemental analysis, XPS, FTIR, TG, and nitrogen adsorption isotherms at -196 degrees C. Evidence for Box ligand location in the supercages of NaY and NaUSY zeolites and its coordination to the exchanged copper(II) was obtained by the several techniques used. The materials were all active in the cyclopropanation of styrene with ethyldiazoacetate at room temperature and diastereoselective toward trans cydopropanes. Although the materials containing Box showed low enantioselectivities, their catalytic activities were higher than the parent copper exchanged zeolites, and did not decrease with reuse, at least during three consecutive cycles

How to avoid discontinuation of antihypertensive treatment. The experience in São Paulo, Brazil

OBJECTIVES: To evaluate the importance of providing guidelines to patients via active telephone calls for blood pressure control and for preventing the discontinuation of treatment among hypertensive patients. INTRODUCTION: Many reasons exist for non-adherence to medical regimens, and one of the strategies employed to improve treatment compliance is the use of active telephone calls. METHODS: Hypertensive patients (n=354) who could receive telephone calls to remind them of their medical appointments and receive instruction about hypertension were distributed into two groups: a) "uncomplicated" - hypertensive patients with no other concurrent diseases and b) "complicated" - severe hypertensive patients (mean diastolic >110 mmHg with or without medication) or patients with comorbidities. All patients, except those excluded (n=44), were open-block randomized to follow two treatment regimens ("traditional" or "current") and to receive or not receive telephone calls ("phone calls" and "no phone calls" groups, respectively). RESULTS: Significantly fewer patients in the "phone calls" group discontinued treatment compared to those in the "no phone calls" group (4 vs. 30; p<0.0094). There was no difference in the percentage of patients with controlled blood pressure in the "phone calls" group and "no phone calls" group or in the "traditional" and "current" groups. The percentage of patients with controlled blood pressure (<140/90 mmHg) was increased at the end of the treatment (74%), reaching 80% in the "uncomplicated" group and 67% in the "complicated" group (p<0.000001). CONCLUSION: Guidance to patients via active telephone calls is an efficient strategy for preventing the discontinuation of antihypertensive treatment

On the continuous Cesàro operator in certain function spaces

“The final publication is available at Springer via http://dx.doi.org/10.1007/s11117-014-0321-5"Various properties of the (continuous) Cesàro operator C, acting on Banach and Fréchet spaces of continuous functions and L p-spaces, are investigated. For instance, the spectrum and point spectrum of C are completely determined and a study of certain dynamics of C is undertaken (eg. hyper- and supercyclicity, chaotic behaviour). In addition, the mean (and uniform mean) ergodic nature of C acting in the various spaces is identified.The research of the first two authors was partially supported by the projects MTM2010-15200 and GVA Prometeo II/2013/013 (Spain).

Pathogenic Escherichia coli, Salmonella spp. and Campylobacter spp. in Two Natural Conservation Centers of Wildlife in Portugal: Genotypic and Phenotypic Characterization

This article belongs to the Section Food Microbiology.Human–wildlife coexistence may increase the potential risk of direct transmission of emergent or re-emergent zoonotic pathogens to humans. Intending to assess the occurrence of three important foodborne pathogens in wild animals of two wildlife conservation centers in Portugal, we investigated 132 fecal samples for the presence of Escherichia coli (Shiga toxin-producing E. coli (STEC) and non-STEC), Salmonella spp. and Campylobacter spp. A genotypic search for genes having virulence and antimicrobial resistance (AMR) was performed by means of PCR and Whole-Genome Sequencing (WGS) and phenotypic (serotyping and AMR profiles) characterization. Overall, 62 samples tested positive for at least one of these species: 27.3% for STEC, 11.4% for non-STEC, 3.0% for Salmonella spp. and 6.8% for Campylobacter spp. AMR was detected in four E. coli isolates and the only Campylobacter coli isolated in this study. WGS analysis revealed that 57.7% (30/52) of pathogenic E. coli integrated genetic clusters of highly closely related isolates (often involving different animal species), supporting the circulation and transmission of different pathogenic E. coli strains in the studied areas. These results support the idea that the health of humans, animals and ecosystems are interconnected, reinforcing the importance of a One Health approach to better monitor and control public health threats.This work was supported by funding from the European Union’s Horizon 2020 Research and Innovation Programme under grant agreement No 773830: One Health European Joint Pro- gramme, as part of the DiSCoVeR project (Discovering the sources of Salmonella, Campylobacter, VTEC and Antimicrobial Resistance).
