O objetivo deste trabalho foi avaliar a viscosidade, a quantidade de água não congelada (w nc) e a temperatura de transição vítrea da fração maximamente crioconcentrada (Tg') de misturas para sherbet, e a incorporação de ar (IAr) dos sherbets, com diferentes concentrações de goma guar (0,2% a 0,5%) e polpa de mangaba (21,1%, 25,8% e 28,6%). A viscosidade aparente variou de 85,8 a 286,1 cP, aumentando com as concentrações de goma guar e mangaba. As análises térmicas com calorímetro diferencial de varredura ...

From a mechanistic standpoint, obstructive sleep apnea (OSA) may further disturb cardiovascular homeostasis in the setting of acute coronary syndrome (ACS).We sought to investigate if a standardized clinical diagnosis of OSA, in acute coronary syndrome patients, predicts the risk of cardiovascular events during hospitalization.In a prospective cohort study, a group of 200 patients diagnosed with ACS between September 2005 and November 2007 were stratified by the Berlin Questionnaire (BQ) regarding ...

Background There is a scarcity of knowledge as to whether rates of myocardial reperfusion use and 30-day mortality for patients with ST-segment-elevation myocardial infarction are similar among patients using the Brazilian Public Health System (SUS) and those using the private healthcare system. Methods and Results A total of 707 patients were analyzed using the VICTIM (Via Crucis for the Treatment of Myocardial Infarction) register database; 589 patients from the SUS and 118 from the private network ...

Objective: The Brazilian-Portuguese hearing in noise test (HINT) was used to investigate the benefit to speech recognition of listening in a fluctuating background. The goal was to determine whether modulation masking release varied as a function of the speech-to-masker ratio at threshold. Speech-to-masker ratio at threshold was manipulated using the novel approach of adjusting the time-compression of the speech. Design: Experiment 1 measured performance-intensity functions in both a steady speech- ...

Myocardial reperfusion is a fundamental part of the treatment for ST elevation myocardial infarction (STEMI) and is responsible for reducing morbidity and mortality in affected patients. However, reperfusion rates are usually lower and mortality rates higher in women compared to men.To evaluate the prevalence of the use of reperfusion therapies among women and men with STEMI in hospitals where percutaneous coronary intervention (PCI) is available in the state of Sergipe.This is a cross-sectional study ...

Splenic hemangiosarcoma (HSA) is a malignant tumor of endothelial cells that affects middle-aged and elderly dogs and is characterized by the formation of new blood vessels, commonly associated with necrotic and hemorrhagic areas. Despite its importance in veterinary medicine, few studies have identified markers with prognostic value for canine HSA. Thus, this study aimed to associate the clinicopathological findings (prostate-specific membrane antigen [PSMA], Claudin-5, and Ki67 gene and protein expression) ...

Modern scanning probe techniques, such as scanning tunneling microscopy, provide access to a large amount of data encoding the underlying physics of quantum matter. In this work, we show how convolutional neural networks can be used to learn effective theoretical models from scanning tunneling microscopy data on correlated moiré superlattices. Moiré systems are particularly well suited for this task as their increased lattice constant provides access to intra-unit-cell physics, while their tunability ...

Chiral three-spin interactions can suppress long-range magnetic order and stabilize quantum spin liquid states in frustrated lattices. We study a spin-1/2 model on the kagome lattice involving a staggered three-spin interaction $J_\chi$ in addition to Heisenberg exchange couplings $J_1$ on nearest-neighbor bonds and $J_d$ across the diagonals of the hexagons. We explore the phase diagram using a combination of a classical approach, parton mean-field theory, and variational Monte Carlo methods. We obtain ...

According to its owners, the Forest of Seu Nico (FSN) from the Viçosa municipality, Minas Gerais, Brazil, never has been logged and is therefore considered a primary forest. Nevertheless, the forest patch suffered impacts due to selective wood and non-timber extraction, fragmentation and isolation. Aim of this study was to test if the FSN, despite impacts, preserved characteristics of primary forests, which are elevated percentages of non-pioneer (>90%), animal-dispersed (>80 %), understory (>50%) and endemic ...

Aims: The aim of this study was to determine the immunoprofile of salivary duct carcinoma and to differentiate intraductal growth from invasive growth. Methods and results: We applied a panel of antibodies (cytokeratins 7, 8, 13, 14, 19, vimentin and α‐smooth muscle actin) in five cases of salivary duct carcinoma. This panel is currently used for identification of different components of salivary gland tumours in our laboratory. All tumour cells were positive for cytokeratins 7 and 8. Few neoplastic ...

Heavy metals are natural non-biodegradable constituents of the Earth's crust that accumulate and persist indefinitely in the ecosystem as a result of human activities. Since the industrial revolution, the concentration of cadmium, arsenic, lead, mercury and zinc, amongst others, have increasingly contaminated soil and water resources, leading to significant yield losses in plants. These issues have become an important concern of scientific interest. Understanding the molecular and physiological ...

Chloroform or dichloromethane extracts of 357 southern Brazilian plant species were tested for the presence of peroxides by thinlayer chromatography, using the spray reagent from Huber & Fröhlke. From the species tested, 71 (20%) showed positive results and most of them (56%) are Asteraceae species. The species tested were mainly from Asteraceae, but 55 more families were screened, in a total of 77 genera surveyed.

Colletotrichum gloeosporioides is a phytopathogenic fungus that gradually weakens both coffee seedlings and adult plants and reduce the quality of the berries. There are no commercial products in the market to control this disease, and therefore, the prospection of different biocontrol agents is a viable option. Phialomyces macrosporus was selected among 10 saprophytic fungi for its higher activity against C. gloeosporioides on coffee seedlings. Foliar application of P. macrosporus to coffee seedlings ...

Myrtaceae are one of the most species-rich families of flowering plants in the Neotropics. They include several complex genera and species; Hexachlamys is one of the complex genera. It has not been recognized as a distinct genus and has been included in Eugenia, based on morphological grounds. Therefore, molecular systematic studies may be useful to understand and to help to solve these relationships. Here, we performed a molecular phylogenetic analysis using plastid and nuclear data in order to ...

Abstract Exergames are consoles that require a higher physical effort to play when compared to traditional video games. Active video games, active gaming, interactive games, movement-controlled video games, exertion games, and exergaming are terms used to define the kinds of video games in which the exertion interface enables a new experience. Exergames have added a component of physical activity to the otherwise motionless video game environment and have the potential to contribute to physical ...

Mammary neoplasms are described as the third most common type of feline tumor, after haematopoietic and skin tumors, and present a challenge for clinicians because the prognosis for feline mammary tumors ranges from guarded to poor. Thus, it is necessary to define new therapeutic approaches and establish more in-depth knowledge about this disease in felines. The main aspects of the diagnosis, prognosis and treatment of feline mammary neoplasia were discussed, aiming to standardize the criteria and ...
