Aims: The present study aims to evaluate the predominance of uropathogens responsible for urinary tract infection (UTI) and determine their resistance patterns, to assess if the recommended empirical treatment is appropriate for the studied population. Samples were collected in Aveiro (Portugal) from an ambulatory service between June 2011 and June 2014. Results: From the 4,270 positive urine samples for UTI, 3,561 (83%) were from women and only 709 (17%) were from men. The bacterium Escherichia coli ...

Fluoride is often found in elevated concentrations in volcanic areas due to the release of magmatic fluorine as hydrogen fluorine through volcanic degassing. The exposure to high levels of fluoride can affect the processes of bone formation and resorption causing skeletal fluorosis, a pathology that can easily be mistaken for other skeletal diseases. In this study, we aimed to determine if fluoride concentration in the femoral bone of wild populations of the house mouse (Mus musculus) is a good biomarker ...

Background HTLV-1 is a retrovirus that causes lymphoproliferative disorders and inflammatory and degenerative diseases of the central nervous system in humans. The prevalence of this infection is high in parts of Brazil and there is a general lack of public health care programs. As a consequence, official data on the transmission routes of this virus are scarce. Objective To demonstrate familial aggregation of HTLV infections in the metropolitan region of Belém, Pará, Brazil. Method A cross-sectional ...

Traumatic brain injury (TBI) is a major cause of death and disability and impairs health-related quality of life (HRQOL). Psychiatric disorders have been recognized as major components of TBI morbidity, yet few studies have addressed the relationship between these outcomes. Sample size, selection bias, and retrospective design, are methodological limitations for TBI-related psychiatric studies. For this study, 33 patients with severe TBI were evaluated prospectively regarding demographic, clinical, ...

We have evaluated buccal epithelial cell micronucleus formation as a biomarker of genotoxic damage following occupational exposure to low doses of ionizing radiation. Buccal epithelial cells were collected from 42 occupationally exposed medical personnel and 39 non-exposed individuals (reference group). Each individual in the exposed group was routinely monitored with a personal radiation badge. The frequency of micronucleated cells (MNC) was significantly higher in the exposed group (5.26 vs. 1.33 ...

This study evaluated the nutritional interrelationship between the growing and finishing phases of crossbred cattle in determining their performance. One hundred and eight animals were used (8 months old, body weight [BW] 211 ± 20 kg). During the dry season, the animals received one of the following supplements: a mineral plus urea supplement (ad libitum, MSD), a protein supplement (1 g/kg BW per day, PR1), or a protein-energy supplement (5 g/kg BW per day, PE). During the rainy season, the animals received ...

Several studies have reported Miocene shallow-marine incursions in the Pebas Megawetland system (Western Amazonia) based on paleontological and sedimentological evidence. Only a few publications restricted to Middle and Late Miocene fossils outcropping in the Iquitos (Peru), Benjamin Constant and Eirunepé (Brazil) areas have provided isotopic evidence to test these incursions.

The fate of vicilins ingested by Callosobruchus maculatus and the physiological importance of these proteins in larvae and adults have been recently investigated. Vicilins have been demonstrated to be absorbed through the midgut epithelium, circulate in their trimeric form in the haemolymph and are deposited in the fat body. In fat body cells of both sexes, vicilins are partially hydrolyzed and the fragments are eventually deposited in the eggs. Tracking the fate of FITC-labelled vicilins in adult ...

The fate of vicilins ingested by Callosobruchus maculatus and the physiological importance of these proteins in larvae and adults were investigated. Vicilins were quantified by ELISA in the haemolymph and fat body during larval development (2nd to 4th instars), in pupae and adults, as well as in ovaries and eggs. Western blot analysis demonstrated that the majority of absorbed vicilins were degraded in the fat body. Tracing the fate of vicilins using FITC revealed that the FITC-vicilin complex was ...

Transforming growth factor beta (TGF-β) plays an important role in carcinogenesis. Two polymorphisms in the TGF-β1 gene (-509C/T and 869T/C) were described to influence susceptibility to gastric and breast cancers. The 869T/C polymorphism was also associated with overall survival in breast cancer patients. In the present study, we investigated the relevance of these TGF-β1 polymorphism in glioma risk and prognosis. A case-control study that included 114 glioma patients and 138 cancer-free controls ...

For several decades, testosterone and its synthetic derivatives have been used for anabolic and androgenic purposes. Initially restricted to professional bodybuilders, these substances gradually became more popular with recreational weightlifters. Considering its increasing prevalence, the consumption of anabolic androgenic steroids (AAS) has become a matter of great concern. Although most side effects are mild and reversible, some of them can cause permanent damage or can be potentially life threatening. ...

Traditional Hardware Description Languages (HDLs) are complex and depend on low-level abstractions, thereby requiring hardware detailed knowledge from developers. In turn, the current HLS tools are based on proprietary or C/C[Formula: see text] derived languages, which allow easier circuit description but decrease performance.
