A simple, green and rapid method for the simultaneous determination of three kinds of quinolone antibiotics (QNs) from environmental water samples and biological samples was established by monolithic spin columns-solid phase extraction coupled with high performance liquid chromatography (MSC-SPE-HPLC). The QNs was completely adsorbed by 300 mg spent coffee grounds as the sorbents of MSC-SPE at 1000 rpm, and eluted by 2500 μL acetonitrile and 4% acetic acid (60:40, V:V). The efficient and rapid elution was obtained under the speed of 500 rpm.

Objetive: We analyzed expression of PECAM-1 and endoglin for a correlation with clinicopathological behavior in CMM. Methods: Control (n = 12), CMN (n = 48), and CMM (n = 44) samples were submitted for immunohistochemistry. PECAM-1 and endoglin expression were counted in the stroma (hot spots) of all samples in order to calculate the MVD. Data analyses were performed using univariate statistical tests, with significance set at p<0.05.

Objetivo: Avaliar segurança e a qualidade de atendimento em pacientes submetidos à endoscopia digestiva alta sob sedação endovenosa com abreviação de jejum. Método: Estudo prospectivo e randomizado em 207 pacientes do Hospital Universitário de Vassouras, Rio de Janeiro, Brasil, indicados para endoscopia digestiva alta. Dividiu-se os pacientes em dois grupos aleatórios por meio desorteio. Em um grupo realizou jejum habitual (6 a 8h) e o outro jejum abreviado para 2h com ingestão de chá enriquecido com maltodextrina a 12,5%.

Este artigo versa sobre a organização da prática pedagógica no fomento da alfabetização científica. Nesta experiência destacamos o planejamento e realização, em parceria, de uma sequência de ensino por investigação planejada para um aluno com Transtorno do Espectro Autista- TEA, intitulada: “Anfíbios e suas transformações”, que envolveu professores: da Educação Especial e de uma turma de 3º ano do Ensino Fundamental.

Objectives: This study is aimed to compare the diagnostic modalities of detecting fungus; KOH mount and Histopathological evaluation in cases of invasive fungal rhinosinusitis. Invasive fungal rhinosinusitis, i.e. fungal invasion of sinus mucosa, submucosa, blood vessels, bone, etc.has emerged as one of the most debilitating sequelae of corona virus infection. This sudden rise in fungal infection may be multifactorial with reasons ranging from low immunity status to uncontrolled diabetes mellitus to incessant steroid use to hyperferritinemia due to Covid Infection.

A pesquisa permitiu obter as definições de Telemedicina aplicadas à Cardiologia e à Regulamentação vigente, mais especificamente, sobre os aplicativos dos fatores de risco da doença cardiovascular. Como resultado, constatamos que os aplicativos ancorados na Sociedade Brasileira de Cardiologia são somente 3 e possuem, aproximadamente, 10.000 usuários, enquanto outros atingem mais de 5.000.000 que não, necessariamente, estão embasados nas regulações vigentes dos diversos órgão reguladores brasileiros.

Introduction: The new severe acute respiratory syndrome coronavirus 2 has led to an unprecedented global health crisis. The high rate of thromboembolic complications in these patients is notorious, but the tools to estimate the risk of these complications are still preliminary. Objective: To describe the rate of thromboembolic events in patients admitted for COVID-19 in a tertiary hospital in Belém - Pará.

Introduction: Endoscopic sinus surgery(ESS) is the first choice of surgery to treat medicine-refractory sinonasal disease. However, when a single lens system is used to perform ESS, the 2-dimensional imaging results in a loss of depth of field. To lessen complications and operate with greater precision, frameless stereotaxic integration of computed tomography(CT) has been used during functional endoscopic sinus surgery(FESS) for intraoperative real time localization.

The purpose of this essay was to critically discuss whether there are and what are the epistemological differences between scientists and designers. These two characters are worked out in the form of extreme stereotypes. The scientist is the ultimate representative of a traditional and positivist view of science, which seeks to explain in a value-free way how the world is. While the designer represents all those who act guided by proposals of value to transform the world, not just explain it.

The study sought to identify the extent to which the use of Mobile Technologies (TM) impacts consumer demand in the agribusiness production chain. To achieve this goal, the TM in which agribusiness managers are inserted was contextualized, the tools that permeate the service to the agribusiness consumer market were mapped and the association between tm adoption and producers' performance in meeting demand was identified. The methodological strategy adopted to outline the research was a field survey with rural producers who sell products in a free fair.
