IDENTIFYING FEBRILE HUMANS USING INFRARED THERMOGRAPHY SCREENING: POSSIBLE APPLICATIONS DURING COVID-19 OUTBREAK

Since the first case of COVID-19 reported at late 2019, it has quickly spread throughout the world and became a pandemic. Because of its high transmission rate, COVID-19 is a huge threat to public health worldwide. Fever is a common symptom of patients with severe acute respiratory syndromes (SARS), including the COVID-19 disease. Infrared thermography (IT) is widely used to mass-screen the skin temperature of people in crowded places, such as hospitals and airports. This is of importance for patients and health professionals as it drastically decreases the risk of transmission due to the minimal contact between the evaluator and the subject. Infrared thermography strategy has already been widely used for the screening of febrile people during the outbreak of other pandemics such as H1N1 and Ebola.  We here describe the potential of IT to identify febrile people who may be infected with COVID-19 and provide recommendations for their monitoring and management during this pandemic based on literature data

Technological and scientific prospection of Piperaceae of the State of Rio de Janeiro - Potential strategy for conservation

Objetiva-se realizar uma prospecção tecnológica e potenciais de usos de espécies da família de Piperaceae do estado do Rio de Janeiro, bem como despertar a importância da ferramenta para potencializar como estratégia de conservação. Para isso foram levantadas as espécies e buscou-se essas no banco de dados de patentes. Verificando suas potencialidades de aplicação e uso sobre indicadores associados as patentes e elaborado pelos autores. Encontrando 21 espécies que apresentaram patentes. Fazendo levantamento mais detalhado para pimenta do reino (Piper nigrum L.), pois apresentou 182 depósitos de patentes, comparando com as outras Piperaceae (n=20). A CIP com maior expressão para Piperaceae foi a A61K. As aplicações foram diversas e responde de forma positiva quando comparado sua inovação com o seu uso populares, demonstrando uma abordagem muito útil para descrição de suas aplicações para o processo estratégica da conservação dessas espécies

Dirhamnosyl flavonoid and other constituents from Brillantaisia palisatii

A mixture containing sitosterol and stigmasterol; a new triterpene 3-epi-ursolic acid; another triterpene mixture comprising a-amyrin, b-amyrin and lupeol; verbascoside, a phenylpropanoid glycoside; and lespedin, a glycosyl flavonoid, were isolated. The less polar compounds (steroids and triterpenoids) were isolated from the hexane partition of the crude ethanolic extract while the more polar ones (phenylpropanoid glycoside and glycosyl flavonoid) were isolated from the ethyl acetate partition of the same extract. The structures of all compounds were established using modern spectrometric methods of elucidation. The spectroscopic data of Lespedin, a rare dirhamnosylflavonol with hypotensor activity and of the triterpene, 3-epi-ursolic acid, are also reported

Bauhinia forficata Link Infusions: Chemical and Bioactivity of Volatile and Non-Volatile Fractions

This study aimed to evaluate Bauhinia forficata infusions prepared using samples available in Rio de Janeiro, Brazil. As such, infusions at 5% (w/v) of different brands and batches commercialized in the city (CS1, CS2, CS3, and CS4) and samples of plant material botanically identified (BS) were evaluated to determine their total phenolic and flavonoid contents (TPC and TFC), antioxidant capacity (ABTS•+, DPPH•, and FRAP assays), phytochemical profile, volatile compounds, and inhibitory effects against the α-amylase enzyme. The results showed that infusions prepared using BS samples had lower TPC, TFC and antioxidant potential than the commercial samples (p < 0.05). The batch averages presented high standard deviations mainly for the commercial samples, corroborating sample heterogeneity. Sample volatile fractions were mainly composed of terpenes (40 compounds identified). In the non-volatile fraction, 20 compounds were identified, with emphasis on the CS3 sample, which comprised most of the compounds, mainly flavonoid derivatives. PCA analysis demonstrated more chemical diversity in non-volatile than volatile compounds. The samples also inhibited the α-amylase enzyme (IC50 value: 0.235–0.801 mg RE/mL). Despite the differences observed in this work, B. forficata is recognized as a source of bioactive compounds that can increase the intake of antioxidant compounds by the population
