In this work we determine the linear and non-linear optical properties of a Fluoro-N-Acylhydrazide derivative (FBHZ), using a combined supermolecule approach and an iterative scheme of electrostatic polarization, where the atoms of neighbouring molecules are represented by point charges. Our results for non-linear optics (NLO) are comparable to those found experimentally, suggesting that FBHZ constitutes an attractive object for future studies and for use as an interesting material for third-order NLO applications...

INTRODUCTION: The purpose of this study was to measure and to compare macular choroidal thickness (CT) between patients with mild Alzheimer's disease (AD), patients without AD, and elderly patients. METHODS: CT was measured manually in 13 locations at 500-μm intervals of a horizontal and a vertical section from the fovea. Linear regression models were used to analyze the data. RESULTS: Fifty patients with a diagnosis of mild AD (73.1 years), 152 patients without AD (71...

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by chronic and systemic inflammation, which leads to the destruction of the cartilage and bone and affects tissues in multiple joints. Oxidative stress has been implicated with regards to involvement in various disease conditions, such as diabetes mellitus and neurodegenerative, respiratory, cardiovascular, and RA diseases. In vivo experimental studies using photobiomodulation therapy (PBMT) have shown positive effects in reducing lipid peroxidation and in increasing antioxidant activity...

The aim of this study was to evaluate the occurrence of Toxoplasma gondii in backyard pigs destined for human consumption in Pernambuco state, Brazil. Blood and tissue samples (liver, heart, brain, lung and diaphragm) were collected from 224 pigs from legal slaughterhouses and tested for T. gondii infection. Antibodies to T. gondii were found in the sera of 37.9% (85/224) by using the immunofluorescence antibody test (cut-off - 1:64). Tissue samples from seropositive pigs were bioassayed in mice. Tissue samples from seropositive pigs and from mice of the bioassay were submitted to histopathology, immunohistochemistry, polymerase chain reaction (PCR) and sequencing; 14...

BACKGROUND AND AIMS: Cardiovascular diseases of thrombotic origin are related to high mortality and standard therapeutic agent used in this case is acetylsalicylic acid (ASA), but serious adverse events may occur. However, recent data has suggested the plant Campomanesia xanthocarpa has antiplatelet activity and could be a viable alternative. In this study we investigated the effects of the encapsulated powder of this plant in human platelet aggregation. METHODS: 23 healthy subjects were randomly divided into three groups: (1) ASA (100mg), (2) C...

OBJECTIVE: Clinical and functional assessment of the surgical treatment for acute injury of the distal insertion of the biceps brachial performed with a surgical technique using a single incision in proximal forearm and fixation with suture anchors in the radial tuberosity. METHODS: This study reviewed the medical records of patients who underwent surgical treatment of distal biceps injury during the period between January 2008 and July 2014. In a mean follow-up of 12 months, 22 patients with complete and acute injury, diagnosed through physical examination and imaging studies, were functionally assessed in the postoperative period regarding the range of motion (degrees of flexion-extension and pronation-supination), the presence of pain (VAS), the Andrews Carson-score, and the Mayo Elbow Performance Score (MEPS)...

Following an emergency department (ED) visit, older adults are more likely to experience poorer outcomes than younger adults. It is crucial to identify older patients using a validated tool. One of the most studied tools is the Identification of Seniors at Risk (ISAR), which is used to identify older adults at risk of adverse outcomes after ED admission. The purpose of the current study was to examine the sensitivity, specificity, and interrater reliability of the Portuguese version of the ISAR when considering early (30 days) and late (180 days) outcomes...

INTRODUCTION: Triple A syndrome (AAAS) is a rare autosomal recessive disorder characterized by alacrima, achalasia, ACTH-resistant adrenal insufficiency, autonomic dysfunction, and progressive neurodegeneration. Increased oxidative stress, demonstrated in patients' fibroblasts in vitro, may be a central disease mechanism. N-acetylcysteine protects renal function in patients with kidney injuries associated with increased oxidative stress and improves viability of AAAS-knockdown adrenal cells in vitro...

The article addresses Brazil's historical development in the use of vital data, incorporating procedures for the evaluation of such data and research with active search of births and deaths, resulting in the proposal of methods for calculating birth and mortality indicators through the use of continuous records. In addition to research to capture vital events from the years 2000 and 2008, the article presents procedures for the correction of events reported to the information systems and the paradigm shift in the method for calculating mortality indicators, resulting from such initiatives...

This article aims to analyze the utility of a local evaluation process developed by administrators and managers of a regional health office in São Paulo, Brazil, and to discuss the need for a well-based choice of theoretical reference to judge this item in participatory approaches. To analyze the organization of the process, the study used the Patton reference, focused on facilitating participants' use of the evaluation. To analyze the evaluation's influence, the dimensions proposed by Weiss, Greene, and Kirkhart were followed...

BACKGROUND: Leptin and its receptor are present in spermatozoa; however, the role of leptin in sperm function is still controversial. Our present study aimed at demonstrating the effect of cryopreservation on sperm DNA fragmentation (DNAf) and investigating the possible effects of sperm capacitation techniques and leptin in vitro incubation on frozen-thawed sperm DNAf and oxidative stress. METHODS: Samples of 45 normospermic men attending for infertility investigation at Vida Centro de Fertilidade, Rio de Janeiro, Brazil, were frozen and thawed with or without capacitation and leptin incubation prior to freezing...

Objective. : To evaluate the efficacy of exercise prior to mammography in reducing perceived postexamination pain. Methods. : An open, randomized, and controlled clinical trial was conducted. The interventions consisted of warm-up and stretching exercises of the upper or lower limbs of women who consulted at Barretos Cancer Hospital, São Paulo State, Brazil. The women were divided into three groups based on the intervention and its location: upper limbs (group 1), lower limbs (group 2), and no intervention (group 0)...

The knowledge of the spatiotemporal dynamics of pathogens and their vectors is an important step in determining the pathogen dispersion pattern and the role of vectors in disease dynamics. However, in the case of mango wilt little is known about its spatiotemporal dynamics and the relationship of its vector [the beetle Hypocryphalus mangiferae (Stebbing 1914)] to these dynamics. The aim of this work was to determine the spatial-seasonal dynamic of H. mangiferae attacks and mango wilt in mango orchards and to verify the importance of H...

BACKGROUND/METHODS: In a pioneering cross-sectional study among Bolivian immigrants in the city of São Paulo, Brazil, the epidemiological profile, clinical manifestations and morbidity of Chagas disease were described. The feasibility of the management of Chagas disease at primary healthcare clinics using a biomedical and psychosocial interdisciplinary approach was also tested. Previously, a Trypanosoma cruzi (T. cruzi) infection rate of 4.4% among 633 immigrants was reported. The samples were screened using two commercial enzyme-linked immunoassay (ELISA) tests generated with epimastigote antigens, and those with discrepant or seropositive results were analyzed by confirmatory tests: indirect immunofluorescence (IFI), TESA-blot and a commercial recombinant ELISA...
