Evaluation of intravascular contrast media transit times in coronary computed tomography angiography.

Objective: To measure the transit times (TTs) of contrast agents among the injection site (antecubital vein), superior vena cava, pulmonary trunk, and ascending aorta, in coronary computed tomography angiography (CTA) examinations of outpatients with no history of cardiovascular or lung disease, thus defining reference values for those TTs.

Materials And Methods: The contrast TTs from the injection site (antecubital vein) to the superior vena cava, from the superior vena cava to the pulmonary trunk, and from the pulmonary trunk to the ascending aorta were measured by monitoring contrast enhancement in real time (bolus tracking). Cardiac output was measured by the geometric method during the CTA examination and was correlated with the contrast TT.

Risks and Benefits of Breastfeeding in COVID-19: Integrative Literature Review.

Objective:  The present article seeks to consolidate existing knowledge on breastfeeding during the SARS-CoV-2 pandemic.

Data Source:  Articles from 2020 and 2021 collected from the PubMed, CAPES, Virtual Health Library, Google Scholar, SciELO, and UpToDate databases were analyzed. Books and government documents published in the last decade (2010-2020) were also consulted.

Importance of computed tomography angiography in acute/hyperacute ischemic stroke.

Objective: To evaluate the importance of computed tomography and computed tomography angiography (CTA) in stroke protocols, as well as their impact on endovascular treatment and on the determination of the etiology.

Materials And Methods: Were evaluated 28 patients with acute/hyperacute stroke in the anterior circulation who underwent intracranial and cervical CTA between April 2018 and August 2019. The parameters evaluated were the degree of stenosis, plaque characteristics, type of infarct, treatment, etiology, and the Alberta Stroke Program Early CT Score (ASPECTS).

Costs and emissions assessment of a Blue Corridor in a Brazilian reality: The use of liquefied natural gas in the transport sector.

Technical, economic, social and environmental conditions are turning natural gas into a feasible solution for sustainable transportation systems in the State of São Paulo (Brazil). Blue Corridors are routes that aim to enable the use of liquefied natural gas (LNG) for heavy vehicles as a substitute to Diesel oil. Therefore, this work proposes four scenarios for a Blue Corridor in the State of São Paulo and analyzes its environmental and economic impacts.

Brazilian red propolis attenuates hypertension and renal damage in 5/6 renal ablation model.

The pathogenic role of inflammation and oxidative stress in chronic kidney disease (CKD) is well known. Anti-inflammatories and antioxidant drugs has demonstrated significant renoprotection in experimental nephropathies. Moreover, the inclusion of natural antioxidants derived from food and herbal extracts (such as polyphenols, curcumin and lycopene) as an adjuvant therapy for slowing CKD progression has been largely tested.

The innovative moments coding system and the assimilation of problematic experiences scale: a case study comparing two methods to track change in psychotherapy.

The Assimilation of Problematic Experiences Scale (APES) and the Innovative Moments Coding System were applied to transcripts of a successful case of linguistic therapy of evaluation independently by different research groups. Assimilation theory and research suggest that higher APES scores reflect therapeutic gains, with a level of approximately 4.0 separating good from poor outcome cases.

Supercapacitor operating at 200 degrees celsius.

The operating temperatures of current electrochemical energy storage devices are limited due to electrolyte degradation and separator instability at higher temperatures. Here we demonstrate that a tailored mixture of materials can facilitate operation of supercapacitors at record temperatures, as high as 200°C. Composite electrolyte/separator structures made from naturally occurring clay and room temperature ionic liquids, with graphitic carbon electrodes, show stable supercapacitor performance at 200°C with good cyclic stability.

NF-κB activation mediates crystal translocation and interstitial inflammation in adenine overload nephropathy.

Adenine overload promotes intratubular crystal precipitation and interstitial nephritis. We showed recently that these abnormalities are strongly attenuated in mice knockout for Toll-like receptors-2, -4, MyD88, ASC, or caspase-1. We now investigated whether NF-κB activation also plays a pathogenic role in this model.

Prevalence and monthly distribution of head lice using two diagnostic procedures in several age groups in Uberlândia, State of Minas Gerais, Southeastern Brazil.

Some epidemiological characteristics of head lice, Pediculus capitis, were studied using two procedures: cut hair analysis and head inspection. Higher prevalence rates were observed in the middle and at the end of the school terms. Both procedures indicated that children were the main reservoir for this type of pediculosis in Uberlândia.

Epidemiological aspects of head lice in children attending day care centres, urban and rural schools in Uberlândia, central Brazil.

From November 1996 to March 2000, a total of 884 children between 0 and 15 years, from 11 institutions including day care centres, public urban and public rural schools in Uberlândia, State of Minas Gerais, central Brazil, were examined for head louse infestation. Children's sex, race, age and some hairs characteristics were shown to be associated to parasite infestation. A prevalence rate of 35% was found and the highest rates were observed in black, female children, with long, dark, wavy hairs.
