The Juiz de Fora Complex, in the region of Três Rios (Rio de Janeiro), consists of rocks with a wide range of composition, from granitic to basic terms. Based on lithogeochemical studies, it was possible to subdivide this unit into four associations: (i) high-K calcalkaline, (ii) medium-K calc-alkaline, (iii) tholeiitic and (iv) alkaline. Geochronological analysis (LA-ICPMS, U-Pb on zircon) yielded: paleoproterozoic ages for the cristalization of a felsic orthogneiss from the medium- K calc-alkaline group; ...

Infection of host cells by Toxoplasma gondii is an active process, which is regulated by secretion of microneme (MICs) and rhoptry proteins (ROPs and RONs) from specialized organelles in the apical pole of the parasite. MIC1, MIC4 and MIC6 assemble into an adhesin complex secreted on the parasite surface that functions to promote infection competency. MIC1 and MIC4 are known to bind terminal sialic acid residues and galactose residues, respectively and to induce IL-12 production from splenocytes. ...

The availability of a reliable and accurate indoor positioning system (IPS) for emergency responders during on-duty missions is regarded as an essential tool to improve situational awareness of both the emergency responders and the incident commander. This tool would facilitate the mission planning, coordination, and accomplishment, as well as decrease the number of on-duty deaths. Due to the absence of global positioning system signal in indoor environments, many other signals and sensors have been ...

Indoor Positioning Systems (IPSs) for emergency responders is a challenging field attracting researchers worldwide. When compared with traditional indoor positioning solutions, the IPSs for emergency responders stand out as they have to operate in harsh and unstructured environments. From the various technologies available for the localization process, ultra-wide band (UWB) is a promising technology for such systems due to its robust signaling in harsh environments, through-wall propagation and high- ...

Mucositis is a cytotoxic side effect caused by chemotherapy drugs, such as 5-Fluorouracil (5-FU), being a serious clinical issue. Lactobacillus spp. could be a helpful strategy to alleviate 5-FU chemotherapy-caused intestinal damage, due to their ability to contribute to intestinal homeostasis through improvement of microbiota balance and immunomodulation. In this work we evaluated the effect of Lactobacillus delbrueckii subsp. lactis CIDCA 133 fermented milk in 5-FU-induced experimental mucositis. ...

This study aimed to evaluate the effect of microcurrent electrical stimulation on pain and area of venous ulcers. In a pilot study for a single-blind controlled clinical trial, carried out at an outpatient clinic during four weeks, 14 subjects with venous ulcers (mean age 62±9 years) were divided in two groups: microcurrent (n=8) and control group (n=6). Pain (by Visual Analogue Scale) and the ulcer area were measured by planimetry. There was a significant difference between the two groups with respect ...

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic in Brazil was dominated by two lineages designated as B.1.1.28 and B.1.1.33. The two SARS-CoV-2 variants harboring mutations at the receptor-binding domain of the Spike (S) protein, designated as lineages P.1 and P.2, evolved from lineage B.1.1.28 and are rapidly spreading in Brazil. Lineage P.1 is considered a Variant of Concern (VOC) because of the presence of multiple mutations in the S protein (including K417T, E484K, N501Y), ...

A prominent goal of policies mitigating climate change and biodiversity loss is to achieve zero deforestation in the global supply chain of key commodities, such as palm oil and soybean. However, the extent and dynamics of deforestation driven by commodity expansion are largely unknown. Here we mapped annual soybean expansion in South America between 2000 and 2019 by combining satellite observations and sample field data. From 2000 to 2019, the area cultivated with soybean more than doubled from ...

A laryngocele is an air-filled dilatation of the saccule of the larynx. An in fected laryngocele is called a laryngopyocele. Our experience with two cases of laryngopyoceles are presented. Only 29 cases of laryngopyoceles have so far been reported in the literature (Illum and Nehen, 1980). Case one had a right-sided combined laryngopyocele and case two had a right-sided combined laryngopyocele and a left-sided combined laryngocele. Both our cases had their lesions excised via an external approach, ...

The effect of tityustoxin (TsTX) on the release of [3H] dopamine in rat brain prefrontal cortical slices was investigated. The stimulatory effect of TsTX was dependent on incubation time and TsTX concentration with an EC50 of 0.05 μM. The release of [3H] dopamine stimulated by TsTX is dependent of Na+ channels and thus, was completely, inhibited by tetrodotoxin. Tityustoxin-induced release of [3H] dopamine was not blocked by ethylene glycol-bis(β-aminoethyl) ether (EGTA) and thus was independent of extracellular ...

The granular cell tumor (GCT) is an uncommon neoplasm, with slow progression, usually benign, that can be found in any organ. The most common region for GCT involvement is in the head and neck. Laryngeal involvement is uncommon and accounts for 6 to 10% of all cases reported. Among the major theories of origin and based on the strongest evidence, the most accepted one is that the tumor stems from neuronal tissue. The GCT has a higher incidence in African-descendent patients, and most commonly in ...

O tumor de células granulares (TCG) é uma neoplasia incomum, de evolução lenta, na maioria dos casos de caráter benigno e que pode acometer qualquer órgão do corpo. Entre as hipóteses que tentam explicar sua origem, a teoria da gênese neural apresenta embasamento sólido e é a mais aceita atualmente. O TCG é mais comum na raça negra, entre a 4ª e 5ª décadas de vida, acometendo com maior freqüência a região da cabeça e pescoço. A localização laríngea é rara, e quando ocorre é mais comum na porção posterior. ...

ABSTRACT Coronal fractures of the anterior teeth are a common form of dental trauma that mainly affects children and adolescents. One of the options for managing coronal tooth fractures when the tooth fragment is available and there is no or minimal violation of the biological width is the reattachment of the dental fragment. Reattachment of fractured tooth fragments can provide good and long‐lasting esthetics (because the tooth’s original anatomic form, color, and surface texture are maintained). ...

Red blood cell (RBC) aggregation in the blood stream is prevented by the zeta potential created by its negatively charged membrane. There are techniques, however, to decrease the zeta potential and allow cell agglutination, which are the basis of most of antigen-antibody tests used in immunohematology. We propose the use of optical tweezers to measure membrane viscosity, adhesion, zeta potential, and the double layer thickness of charges (DLT) formed around the cell in an electrolytic solution. For ...

The aim of the present work was to identify the extractable phenolic compounds present in cork from Quercus suber L. The structures of thirty three compounds were tentatively identified by liquid chromatography coupled to electrospray ionisation mass spectrometry (HPLC–DAD/ESI–MS). The majority of those compounds were gallic acid derivatives, in the form of either galloyl esters of glucose (gallotannins), combinations of galloyl and hexahydroxydiphenoyl esters of glucose (ellagitannins), dehydrated ...
