1. Comparative Study of Some Numerical Schemes for a Fractional Order Model of HIV Infection Treatment
ABSTRACT A fractional order mathematical model that already exists in the literature, was considered. This model was established to study the effects of medicinal treatment in people infected with the human immunodeficiency virus (HIV). The importance of this study is that the model evaluates, among other parameters, the density of healthy and HIV-infected C

2. Thermophysical and Transport Properties of the BaCl2-CsCl High Temperature Ionic Liquid Mixtures
High temperature ionic liquids (HTILs) densities and transport properties for mixtures BaCl2 CsCl, x(BaCl2) = 0-1, have been studied as a function of composition and temperature. In terms of Arrhenius theory, the temperature correlation of all measured properties was made and discussed. Thermodynamic properties (isothermal compressibility, molecular volume,

3. Biomechanical and biochemical investigation of erythrocytes in late stage human leptospirosis
Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira, which can cause lipid changes in the erythrocyte membrane. Optical tweezers were used to characterize rheological changes in erythrocytes from patients with leptospirosis in the late stage. Biochemical methods were also used for quantification of plasma lipid, erythrocyte membran

4. Type B insulin resistance syndrome: a systematic review
ABSTRACT A literature review on the clinical, laboratory, and treatment features of type B insulin resistance syndrome (TBIRS). Data from PubMed, the Virtual Health Library and Cochrane database were selected and analyzed using the REDCap application and R statistical program. From 182 papers, 65 were selected, which assessed 119 clinical cases, 76.5% in fem

5. Severe malnutrition after bariatric surgery and clinic manifestations of infection
RESUMO Este relato descreve a evolução pós-cirurgia bariátrica de uma paciente obesa que apresentou baixa adesão à dieta e suplementação de micronutrientes. Quatro anos após duas cirurgias bariátricas, a paciente foi internada por perda transitória de consciência, raciocínio lento, anasarca, hipoalbuminemia grave, além de deficiências vitamín

6. Comparison of different quantification methods for 18F-fluorodeoxyglucose-positron emission tomography studies in rat brains
OBJECTIVES: This study aimed to evaluate several methods to estimate glucose consumption in the male Wister rat brain as measured by PET. METHODS: Fourteen male Wistar normoglycemic rats were studied. The input function consisted of seventeen blood samples drawn manually from the femoral artery. Glucose uptake values were calculated using the input functio

7. A GENERALIZED ABOVEGROUND BIOMASS MODEL FOR JUVENILE INDIVIDUALS OF Rhododendron arboreum (SM.) IN NEPAL
ABSTRACT Carbon in the juvenile plants contribute significant share to the total carbon stock in forests. A precise estimate of aboveground biomass of the juvenile stages of trees is therefore very important. We developed a generalized allometric biomass model for the prediction of aboveground biomass of the juvenile individuals of Rhododendron arboreum (Sm.

8. Invasive Coronary Physiological Assessment in Symptomatic Middle-Aged Endurance Athletes
Abstract Despite the health benefits of routine exercise, coronary artery disease (CAD) is common among older competitive athletes and is an important cause of sudden cardiac death. Athletes with suspected or confirmed CAD routinely undergo conventional coronary angiography involving the performance of invasive coronary physiological assessment using the fra

9. Obesity and dental caries among South Brazilian schoolchildren: a 2.5-year longitudinal study
Abstract The aim of this study was to assess the association between weight status and ΔDMFS among 12-year-old schoolchildren from South Brazil. A total of 801 12-year-old schoolchildren were followed-up for 2.5 ± 0.3 years. Data collection included questionnaire, recording of anthropometric measures (height and weight), and caries examination. The outcome

11. Experimental bedforms by saline density currents
Abstract Bedforms are sedimentary features that can be generated on the seafloor by the interaction between density currents and mobile beds. Developing knowledge about the hydraulic and sedimentary processes involved during these events is in the interest of research groups and oil companies. Because of the magnitude of the density currents in its natural e

12. Optimization of Atmospheric Pressure Photoionization for the Crude Oil Analysis Using Ultra-High Resolution Mass Spectrometry
Design of experiments (DOE) applied to mass spectrometry (MS), mainly focusing on the optimization of ionization techniques, has been applied to optimize experiments in order to provide the highest amount of information with the lowest number of experiments. However, DOE has not been used in petroleomics. For the first time, we applied DOE to optimize the ma
