1. THEORETICAL STUDIES ON DIACETONEDIPEROXIDE DERIVATIVES AND COMPARISONS WITH OTHER MULTI-PEROXIDIC COMPOUNDS
Diacetonediperoxide (DADP) derivatives were investigated with density functional theory (DFT) methods at the DFT-B3LYP and M06-2X/6-311++G (d, p) levels and were also compared with other multi-peroxidic compounds. The investigated derivatives were 3,6-dimethyl-3,6-diamine-1,2,4,5-tetraoxane (DADPNH2), 3,6-dimethyl-3,6-dinitro-1,2,4,5-tetraoxane (DADPNO2), an

2. Evaluation of the Heat and Energy Performance of a Datacenter Using a New Efficiency Index: Energy Usage Effectiveness Design – EUED.
Abstract Data Centers are growing steadily worldwide, and they are expected to continue growing up to 53% in 2020. Energy efficiency, in high power consumption, is a key venue. There are methodologies to measure this efficiency, one example is using the PUE (Power Usage Effectiveness) index. In this paper is proposed a new index for measuring efficiency at

4. Decreased respiratory performance of children and adolescents with myelomeningocele who use a wheelchair – preliminary data
Myelomeningocele (MMC) is a neural tube defect that often causes spinal cord injury at the thoracolumbar region, as well as sensory and motor paralysis in the lower limbs. This leads to continuous use of a wheelchair and, consequently, a sedentary lifestyle, predisposition to muscle weakness, cardiovascular and respiratory disorders, obesity, and structural

5. Evaluation of preoperative ultrasonographic and biochemical features of patients with aggressive parathyroid disease: is there a reliable predictive marker?
ABSTRACT Objective Parathyroid cancer (PC) represents < 1% of cases of PHPT. Tumors demonstrating atypical histopathologic features and don’t fulfill criteria for carcinoma are classified as atypical adenomas (APA). The purpose of this study was to determine a biochemical or ultrasonographic feature that can predict aggressive disease requiring more exte

6. An update on the epidemiological situation of spotted fever in Brazil
Abstract Background Spotted fever is a tick-borne rickettsial disease. In Brazil, its notification to the Ministry of Health is compulsory. Since 2007, cases of spotted fever have been integrated to the Notifiable Diseases Information System, and epidemiological analyzes are part of the routines on surveillance programs. Methods This descriptive study up

7. Simplified hemostatic technique during laparoscopic partial nephrectomy
INTRODUCTION: Laparoscopic partial nephrectomy (LPN) has gained popularity in recent years, although it remains a challenging procedure. Herein we describe our technique of renal defect closure using sutures as the sole means of hemostasis during LPN. SURGICAL TECHNIQUE: The kidney is approached transperitoneally in a standard fashion. After the renal artery

8. Helicobacter pylori e polimorfismos em enzimas de reparo de DNA e de sÃntese de Ãxido nÃtrico no cÃncer gÃstrico / Helicobacter pylori infection and polymorphisms in DNA repair enzymes and iNOS in gastric cancer
Gastric cancer is the most deadly malignant neoplasia worldwide, with high incidence in Brazil and Helicobacter pylori infection is a well-established risk factor. Depending on the presence of virulence genes such as cagA, cagE, vacA and virB11, H. pylori can cause differentiated inflammatory responses, with large amounts of nitric oxide (NO) generated prima

9. Occurrence of Aggregatibacter actinomycetemcomitans in Brazilians with chronic periodontitis
Studies have suggested that A. actinomycetemcomitans is involved in the aetiology of aggressive periodontitis as well as in chronic periodontitis. This study was aimed at elucidating the occurrence of A. actinomycetemcomitans in a Brazilian population with chronic periodontitis. A total of 555 (mean age 33.04 ± 12.45) individuals, living in two large areas

10. Estudo do mecanismo de transferência horizontal da sequência de inserção IS1245, específica de Mycobacterium avium, para Mycobacterium kansasii / Study of the mechanism of horizontal transfer of insertion sequence IS1245, specific of Mycobacterium avium, to Mycobacterium kansasii
Mycobacterium avium and Mycobacterium kansasii are non-tuberculous mycobacteria frequently isolated in infections from HIV positive patients. In a previous study from our laboratory, a mixed culture of M. avium and M. kansasii from a bone marrow isolate of an HIV positive patient was studied. The analysis of isolated colonies allowed the detection of the ins

11. Caracterização comparativa do esmalte de dentes decíduos e permanentes por Espectroscopia Raman
The aim of this study was the characterization of primary and permanent teeth enamel, producing comparison parameters to future studies. The Raman spectroscopy identifies the content of organic and inorganic matters through polarized change associated with molecule vibration modes. Third permanent (n=15) and second primary molars (n=15) were used. Samples we
