The studies on chemical composition and biological activity of propolis had focused mainly species Apis mellifera L. (Hymenoptera: Apidae). There are few about the uncommon collected by stingless bees Meliponini tribe known as geopropolis. geopropolis from Scaptotrigona postica was in region Barra do Corda, Maranhão state, Brazil. analysis hydromethanolic extract this (HMG) carried out through HPLC-DAD-ESI-MS/MS main constituents found were pyrrolizidine alkaloids C-glycosyl flavones....
Varicella vaccine was introduced into the Brazilian Immunization Program in October 2013, as a single-dose schedule administered at 15 months of age. Its effectiveness had not yet been assessed country.A matched case-control study carried out São Paulo and Goiânia (Southeast Midwest regions, respectively), Brazil. Suspected cases, were identified through prospective surveillance established sites. All cases specimens from skin lesion collected for molecular laboratory testing. Cases...
The search for functional foods, which possess bioactive substances, is a new trend the obtention of alternative and more effective treatments many diseases with fewer side effects. Geopropolis, elaborated by stingless bees, mixture plant resin sources, wax soil. In geopropolis from Scaptotrigona affinis postica (Latreille, 1807), (Hymenoptera, Apidae, Meliponini) was not observed presence previous study, extract provided beekeeper, S. Barra do Corda, Maranhão State, exhibited...
During a resurgence of measles in São Paulo, Brazil, 1997, >40,000 cases (peak incidence rate 246/100,000 inhabitants) and 42 measles-related deaths were reported. Reverse transcriptase-polymerase chain reaction nucleotide sequencing used to analyze specimens from patients who had typical clinical infection during this outbreak six 1995 1996. Although wild-type viruses (genotypes D5 D6) present Paulo before resurgence, we detected only D6 viruses. The genotype isolated identical sequences...
Abstract Respiratory syncytial virus (RSV) is the most common cause of severe respiratory infections worldwide, and an important childhood bronchiolitis, pneumonia, mortality. Although prevention RSV infection by immunoprophylaxis with palivizumab has proved effective, a precise understanding timing outbreaks necessary to ensure that infants are protected when circulating. In this study consistent shift in seasonal patterns circulation southeast Brazil (São Paulo) reported based on analysis...
A palmeira ráfia (Rhapis excelsa), possui elevado valor comercial, sendo utilizada na composição de vasos e jardins, principalmente em interiores. No entanto, poucas são as informações sobre sua exigência adubação ou mesmo condições ótimas sombreamento. Para sombreamento, além do tradicional sombrite, estão disponíveis atualmente no mercado malhas fotoconversoras, que estimulam o desenvolvimento das espécies vegetais. Objetivou-se nesse trabalho avaliar a influência diferentes porcentagens...
OBJECTIVE: The clinical differential diagnosis of rash due to viral infections is often difficult, and misdiagnosis not rare, especially after the introduction measles rubella vaccination. A study determine etiological exanthema was carried out in a group children METHODS: Sera collected from with who received vaccine were reported 1999. They analyzed for IgM antibodies against virus, human parvovirus B19 (HPV B19) using ELISA commercial techniques, herpes virus 6 (HHV 6) immunofluorescence...
O uso de telas coloridas representa um novo conceito agrotecnológico, que pretende combinar a proteção física das plantas com filtragem seletiva da radiação solar para promover respostas fisiológicas desejáveis, reguladas pela luz. objetivo deste trabalho foi verificar o efeito do sombreamento sobre características biométricas, anatômicas e Artemisia vulgaris. As foram cultivadas em vasos distribuídos inteiramente ao acaso sob os tratamentos tela colorida tipo Cromatinet (50%) vermelha, azul...
Acute liver failure is a syndrome with wide range of etiologic possibilities in children, but up to 50% the cases literature no diagnosis established. This case report adds rubella virus list possible causes acute failure. association was made by serologic, cell culture, molecular, histopathologic, and immunohistochemical methods.
Compared to previous years, seasonal influenza activity commenced early in São Paulo State, Brazil, Southern hemisphere during the 2016 year. In order investigate genetic pattern of A(H1N1)pdm09 State Sao a total 479 respiratory samples, collected January by Sentinel Surveillance Units, were screened real-time RT-PCR. A 6 Influenza viruses presenting ct values ≤ 30 sequenced following phylogenetic analysis. The present study identified circulation new 6B.1 subgroup (A/Sao Paulo/10-118/2016...
Abstract Rubella virus (RV) infection during the early stages of pregnancy can lead to serious birth defects, known as congenital rubella syndrome (CRS). This retrospective study was conducted between 1996 and 2009 with surveillance specimens collected from patients suspected (CRI) CRS. The clinical samples (nine amminiotic fluid, eight urine, blood, one conception product, placenta) were sent for viral isolation genotyping. Twenty‐seven sequences analysed four genotypes (1a, 1B, 1G, 2B)...
Summary Introduction: Virus surveillance strategies and genetic characterization of human parvovirus B19 (B19V) are important tools for regional global control viral outbreak. In São Paulo, Brazil, we performed a study B19V by monitoring the spread this virus, which is an infectious agent could be mistakenly reported as rash other types infection. Method: Serum samples were subjected to enzyme immunoassay, real time polymerase chain reaction, sequencing. Results: From 462 patients with...
Studies about viral infections have a great importance in human and veterinary health, the number of medications available to treatment these diseases is very reduced, making search for antiviral molecules an important focus scientific research. Propolis bee material manufactured by mix exudate plants, saliva wax. This product used seal hive involve dead invaders. Their chemical profile variable, depending on geographic origin plant conditions growth. The use propolis (bee-glue) various...
Abstract Rubella virus (RV) is an important human pathogen that causes rubella, acute contagious disease. It also severe birth defects collectively known as congenital rubella syndrome when infection occurs during the first trimester of pregnancy. Here, we present phylogenetic analysis RV circulated in São Paulo 2007–2008 outbreak. Samples collected from patients diagnosed with were isolated cell culture and sequenced. RNA was obtained samples or RV‐infected cultures amplified by reverse...
In this paper, we analysed the haemagglutinin (HA) gene identified by polymerase chain reaction from 90 influenza A H1N1 virus strains that circulated in Brazil April 2009-June 2010. World Health Organization sequencing protocol allowed us to identify amino acid mutations HA protein at positions S220T (71%), D239G/N/S (20%), Y247H (4.5%), E252K (3.3%), M274V (2.2%), Q310H (26.7%) and E391K (12%). fatal outcome was associated with D239G mutation (p < 0.0001).
