Here, a new and inexpensive electrochemical paper-based analytical device (ePAD) containing a pencil-drawn three-electrode setup, in which the working electrode was modified with graphene nanoribbons (GNRs), is presented for the first time. Under optimal conditions, the GNRs-ePAD provided higher peak currents (ca. 91 %), lower electron transfer resistance (ca. 32-fold) and greater electroactive area (more than twice) when compared to the unmodified ePAD. This significant improvement can be attributed to the increase in the number of active sites available on the electrode surface due to the high conductivity of GNRs. In addition, the ePAD showed good reproducibility and acceptable repeatability, with relative standard deviations (RSDs) ≤ 8.4 % for peak currents and peak potentials. As proof of concept, the GNRs-ePAD was employed for analysis of 5-HTP in pharmaceuticals. As far as we know, this is the first report of the use of ePADs for determination of 5-HTP. The electroanalytical quantification was carried out using square-wave voltammetry (SWV). A linear range from 25 to 1000 μmol L⁻¹ and a limit of detection of 7.6 μmol L⁻¹ were obtained. The sensitivity achieved with the GNRs-ePAD was almost 5-fold greater than that obtained with the bare electrode. The results achieved during the analysis of pharmaceutical products showed good precision (RSD < 3 %) and great concordance with the values found by UV–vis spectrophotometry, utilized for comparison (relative error was < 2 %). None interference or matrix effects were observed during measurements. These results demonstrate promising potential for the GNRs-ePAD proposed here. This device shows itself as an interesting, efficient and low-cost analytical platform for analysis of electroactive species, being specially interesting for places with limited resources. © 2022 Elsevier B.V.

Background: Soccer related injuries are often reported in studies, but epidemiological research on this theme is rare in Brazil, Furthermore, the conditions in which athletes have returned to sports practice, namely, either symptomatic or asymptomatic, have been neglected in research. Objectives: The aim of this study was to describe the epidemiological features of injuries among professional Brazilian soccer players in relation to location, type, mechanism, severity, recurrence, treatment and, lastly, symptoms in return to sport. Study design: Descriptive and cross-sectional, observational study. Study center: School of Physical Therapy of the University of Mato Grosso do Sul, Brazil. Methods: 116 male professional athletes of teams from a Brazilian state championship were interviewed and information about injuries was recorded using a retrospective reported morbidity questionnaire. Data were analyzed in mean ± SD for physical characteristics and sports practice history in absolute and relative frequencies (chi-square test with Bonferroni's correction) for characterization of soccer injuries in terms of type, location, severity, recurrence and symptoms in return to sport. Results: The numbers of injuries per athlete and per injured athlete were 0.92 and 1.43 respectively. The injuries of muscle-tendon unit and the joint types localized on lower limbs constituted the most important clinical occurrences with significant difference both in relation to other types (p < 0.05). Moderate and severe injuries were the most frequent occurrences. In relation to mechanisms for each type of injury, body contact was at least three times more responsible for injury cases. This type of mechanism was associated with a significantly greater impairment of joint structures. Concerning occurrence and recurrence of cases, the number of recurrent injuries of the muscle-tendon unit reached about 7.5% of the first-time injuries, while the number of joint recurrent injuries integrated almos

Objective: To identify the urban phlebotomine sandfly fauna in Ponta Porã, Mato Grosso do Sul State, Brazil. Methods: The captures were undertaken from April 2009 to March 2010 with CDC light traps in 14 ecotopes (intra and peridomicile) in different areas of the city, Shannon traps being used in areas with abundant vegetation. Results: A total of 707 specimens were captured with CDC light traps (565 males and 142 females) and 155 specimens (112 males and 43 females) with Shannon traps, a total of 862 phlebotomines. The specimens captured belonged to eight species: Lutzomyia longipalpis (Lutz & Neiva, 1912), Evandromyia cortelezzii (Brethes, 1923), Sciopemyia sordelli (Shannon & Del Ponte, 1927), Pintomyia pessoai (Coutinho & Barretto, 1940);Pintomyia monticola (Costa Lima, 1932);Brumptomyia brumpti (Larousse, 1920);Nyssomyia whitmani (Antunes & Coutinho, 1939) and Psathyromyia shannoni (Dyar, 1929). Lutzomyia longipalpis, the main vector of Leishmania (Leishmania) chagasi, was the species most frequently captured (97.03%) and also the most abundant according to the standardized abundance index (SAI)=0.86. Conclusions: The highest species richness was captured, with CDC light traps, inside the domiciles and the species diversity and evenness in the peridomicile, clearly indicating a preference for anthropic environments. © 2012 Asian Pacific Tropical Medicine Press.

Objective: Visceral leishmaniasis has been reported in all Brazilian regions and, in Mato Grosso do Sul State, the occurrence of cases has increased significantly. The objective of this study was to identify the natural infection of phlebotomines by Leishmania in Ponta Porã, a Brazilian county bordering Paraguay. Methods: By using light CDC and Shannon traps, 185 sandfly females were captured, dissected and arranged in 107 pools subjected to DNA extraction and amplification by Polymerase chain reaction. Results: From the samples subjected to amplification, the fragment of 120 bp characteristic of Leishmania sp was observed in one of the groups, which is composed by a female species of Evandromyia cortelezzii (Brèthes, 1923). Conclusions: The minimum infection rate calculated for Ponta Porã was 0.54%, and the occurrence of flagellates and the confirmation of natural infection by Leishmania chagasi pose a serious concern for the transmission of visceral leishmaniasis in the region. © 2011 Asian Pacific Tropical Medicine Press.
