1. Comparison of vena cava distensibility index and pulse pressure variation for the evaluation of intravascular volume in critically ill children
Abstract Objective: In this study, the authors aimed to evaluate the effectiveness of the vena cava distensibility index and pulse pressure variation as dynamic parameters for estimating intravascular volume in critically ill children. Methods: Patients aged 1 month to 18 years, who were hospitalized in the present study’s pediatric intensive care unit,

2. The clinical impact of the systolic volume variation guided intraoperative fluid administration regimen on surgical outcomes after pancreaticoduodenectomy: a retrospective cohort study
Abstract Background Pancreaticoduodenectomy is associated with high morbidity. Many preoperative variables are risk factors for postoperative complications, but they are primarily non-modifiable. It is not clear whether an intraoperative goal-directed fluid regimen might be associated with fewer postoperative surgical complications compared to current conse

3. Kidney surface development in human fetuses: study applied to radiological diagnosis
ABSTRACT Objective: To evaluate the anatomical aspects of the kidney surface in human fetuses during the second gestational trimester. Material and Methods: We studied 108 kidneys obtained from 54 human fetuses (29 males and 25 females). The kidney was dissected and the number of clefts was counted. The renal volume was also assessed. To compare the quanti

4. Porosity of CHA Zeolite Driving the Formation of Polyaromatic Coke Species in the Methanol to Olefins Reaction
The pore size of the chabazite structure is exceptionally suitable for the methanol to olefins (MTO) reaction. The reaction has an induction period required for the formation of a hydrocarbon pool (HP), usually composed of aromatic compounds of different sizes. HP is alkylated by methanol and afterward cracked, leading to the formation of olefins. Despite th

5. A prospective randomized study comparing bipolar plasmakinetic transurethral resection of the prostate and monopolar transurethral resection of the prostate for the treatment of Benign Prostatic Hyperplasia: efficacy, sexual function, Quality of Life, and complications
ABSTRACT Objective: To generate high-quality data comparing the clinical efficacy and safety profile between monopolar transurethral resection of the prostate (M-TURP) and bipolar plasmakinetic resection of the prostate (PK-TURP) for benign prostatic hyperplasia (BPH). Materials and Methods: Prospective, randomized, single-blinded study conducted in a tert

6. FITTING AND CALIBRATING A MIXED-EFFECTS SEGMENTED TAPER MODEL FOR BRUTIAN PINE
ABSTRACT Taper models are one of several necessary tools in modern forest inventory, giving information on diameter at any point along the tree stem and this information can also be used to estimate stem volume. In this study, we used nonlinear mixed-effects (NLME) modeling approach to minimize existing statistical problems in constructing taper equations. A

7. Efecto de la PEEP sobre el componente resistivo inspiratorio en pacientes con sindrome de distrés respiratorio agudo ventilados a bajo volumen corriente
ABSTRACT Objective: To describe the behavior of inspiratory resistance components when positive end-expiratory pressure (PEEP) increases in patients with acute respiratory distress syndrome under a protective ventilation strategy. Methods: In volume-controlled mode, at 6mL/kg and constant flow, end-inspiratory occlusions were performed at 0, 5 10, 15 and 2

9. Ultrasonographic features of the normal thyroid gland in adult horses
RESUMO: Poucas análises foram publicadas com relação ao uso da ultrassonografia como método de avaliação da glândula tireoide hígida em equinos. Alguns trabalhos incluem a determinação das dimensões e características do parênquima. Por essas razões, este estudo teve como objetivo determinar com segurança as medidas tireoidianas a partir da com

10. Antidepressivos, ansiolíticos, hipnóticos e sedativos: uma análise dos gastos em Minas Gerais
Resumo A alocação de recursos com a aquisição de medicamentos é um dos maiores desafios para a efetivação da assistência farmacêutica no SUS. No entanto, poucos estudos avaliam a evolução desses gastos no nível estadual, especialmente com as classes dos antidepressivos, ansiolíticos e hipnótico-sedativos. O objetivo do estudo foi analisar e ide

11. Phenotypic Characterization and Genetic Diversity of Sugarcane Varieties Cultivated in Northern Karnataka of India based on Principal Component and Cluster Analyses
Abstract: Sugarcane is a major commercial crop grown in India and across the world. Hence, several elite varieties have been developed now-a-days to overcome many obstacles including abiotic stresses and diseases. The present study was undertaken to screen genetic variation among twenty four sugarcane varieties that are commonly cultivated across Northern Ka

12. A desvalorização cambial e a exportação de produtos florestais madeireiros
Resumo O objetivo deste artigo é analisar o comportamento das exportações de produtos madeireiros do setor florestal após a desvalorização cambial, a partir de 2012. O método de avaliação de impacto foi o de diferença em diferenças (DD). Os resultados apontam que, apesar de as exportações representarem, em média, volume menor que a comercializa
