The development of a digestive system is an essential feature of bilaterians. Studies of the molecular control of gut formation in arthropods have been studied in detail in the fruit fly Drosophila melanogaster. However, little is known in other arthropods, especially in noninsect arthropods. To better understand the evolution of arthropod alimentary system, we investigate the molecular control of gut development in the spider Parasteatoda tepidariorum (Pt), the primary chelicerate model species for developmental studies...

The hemiptera Rhodnius prolixus is a blood-feeding insect and a primary vector of Trypanosoma cruzi, the etiological agent of the Chagas disease. Over the past century, Rhodnius has been the subject of intense investigations, which have contributed to unveil important aspects of metabolism and physiology in insects. Recent technological innovations are helping dissect the genetic and molecular underpinnings of Rhodnius embryogenesis and organogenesis, thus fostering the use of this important species in the fields of developmental and evolutionary biology...

Aims: Oversensing can interfere with biventricular pacing. Cardiac Resynchronization Therapy (CRT) output inhibition due to automatic brady mode change from a sensing to a pacing mode of a previously implanted pacemaker as it reached battery capacity depleted indicator has not been previously published in the medical literature. Methods and Results: We report the first case of CRT output inhibition in a pacemaker dependent patient due to electrical stimuli from a previously right-sided implanted pacemaker, after unaware reversion of OVO mode (O = no chambers paced; V = ventricular sensing; O = no response to sensing) to backup VVI (V = ventricular pacing; V = ventricular sensing; I = inhibitory response to sensing) when it reached the elective replacement interval...

Gathering evidence supports the existence of a population of cells with stem-like characteristics, named cancer stem cells (CSC), which is involved not only in tumor recurrence but also in tumorigenicity, metastization and drug resistance. Several markers have been used to identify putative CSC sub-populations in different cancers. Notwithstanding, it has been acknowledged that breast CSC may originate from non-stem cancer cells (non-SCC), interconverting through an epithelial-to-mesenchymal transition-mediated process, and presenting several deregulated canonical and developmental signaling pathways...

BACKGROUND: Excessive air pollution in urban environments can impact morbidity and mortality. The authors evaluated the role of particulate matter2.5 (PM2.5) in structural, geometric, and functional remodeling in hearts, using an experimental model of myocardial infarction. METHODS AND FINDINGS: Seventy-five rats were divided into 5 groups: control (CG), CG exposed to PM2.5 pollution (CGP), myocardial infarcted group (MI), infarcted group immediately exposed to pollution (IGP-I), and infarcted group previously exposed to pollution and kept exposed after infarction (IGP-II)...

Cognitive development in children presents peculiarities according to groups of age, gender, and type of school. Few studies have been investigating the effects of all these factors. The aim of this study was to investigate the main effects and the interactions of age, gender, and type of school in 419 children from ages 6 to 12 years old evaluated by the Child Brief Neuropsychological Assessment Battery (NEUPSILIN-Inf). Older children, children in private schools and girls presented better results. Interactions between all three independent variables were observed in different cognitive domains...

Endocannabinoids are bioactive lipids that modulate various physiological processes through G-protein-coupled receptors (CB1 and CB2) and other putative targets. By sharing the activation of the same receptors, some phytocannabinoids and a multitude of synthetic cannabinoids mimic the effects of endocannabinoids. In recent years, a growing interest has been dedicated to the study of cannabinoids properties for their analgesic, antioxidant, anti-inflammatory and neuroprotective effects. In addition to these well-recognized effects, various studies suggest that cannabinoids may affect cell survival, cell proliferation or cell death...

The aim of this study was to evaluate the immunocytochemistry (ICC) to diagnose trichomoniasis, particularly asymptomatic infections. By culture serial dilutions, ICC was able to detect 1 trophozoite/mL, while the culture was positive up to 100 trophozoites/mL. The ICC in vivo detection capability was assessed in vaginal secretions of mice experimentally infected and in vaginal swabs from asymptomatic HIV-positive pregnant women compared with culture. All vaginal secretion samples from mice were positive according to both methods...

To determine the incidence and severity of all-terrain vehicle crashes (ATVCs) compared with motorcycle crashes (MCCs) in all critically injured patients. Prospective data were retrospectively reviewed on 1840 patients involved in ATVCs and MCCs admitted to a rural level one trauma center over 16 years. ATVC patients (n = 655) were younger (25 vs 38, P < 0.0001), more likely female (20% vs 11%, P < 0.001), less severely injured (13.5 vs 16, P < 0.0001), had similar Glasgow Coma Score (13.3 vs 13.4, p = NS), less helmet use (6% vs 69%, P < 0...

BACKGROUND: Worldwide, the incidence of cancer in young adults (20-39 years) is increasing, and represents an important cause of mortality in this age group. A retrospective study was undertaken to provide information that may lead to improved treatment outcomes. METHODS: Epidemiological, clinicopathological, treatment, and survival information were retrieved from the electronic database registry of a tertiary referral hospital in São Paulo, Brazil for patients 19-29 years of age diagnosed with cancer between January 2007 and December 2012...

BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is a safe procedure and major morbidity is unusual. However, the number of PEG fed patients is increasing all over the world and complications may become more and more frequent. CASE REPORT: We describe a 73 years old woman with persistent vomit after replacement of the standard PEG tube with a Foley catheter. An upper GI endoscopy showed the catheter pulled into the duodenum causing gastric outlet obstruction...

This work aimed at characterizing the thermal balance of Nellore cattle from the system of indirect calorimetry using a facial mask. The study was conducted at the Animal Biometeorology Laboratory of the São Paulo State University, Jaboticabal, Brazil. Five male Nellore weighing 750 ± 62 kg, at similar ages and body conditions were distributed in four 5 × 5 Latin squares (5 days of records and five schedules) during 20 days. Physiological and environmental measurements were obtained from the indirect calorimetry system using a facial mask...

The design of screening methods for the detection of genetically modified organisms (GMOs) in food would improve the efficiency in their control. We report here a PCR amplification method combined with a sequence-specific electrochemical genosensor for the quantification of a DNA sequence characteristic of the 35S promoter derived from the cauliflower mosaic virus (CaMV). Specifically, we employ a genosensor constructed by chemisorption of a thiolated capture probe and p-aminothiophenol gold surfaces to entrap on the sensing layer the unpurified PCR amplicons, together with a signaling probe labeled with fluorescein...

BACKGROUND AND PURPOSE: Intravenous alteplase (rtPA) may be associated with seizures and epileptic activity in the electroencephalogram (EEG). The aim of this work was to compare the frequency of seizures and EEG abnormalities between stroke patients treated and not treated with rtPA. METHODS: This was a prospective study of consecutive acute anterior circulation ischaemic stroke patients, with 1-year follow-up. Patients were previously independent, had an admission National Institute of Health Stroke Scale score ≥4, an acute ischaemic lesion and no previous seizures...

OBJECTIVE: To evaluate the effects of three different radiotherapy doses (20, 40, and 70Gy) on the microhardness, superficial morphology, and mineral content (based on Ca and P values) of three different depths of human enamel (cervical, middle, and occlusal). DESIGN: Thirty-four third molars were cut, separated, and prepared. Microhardness samples (n=30) were embedded in acrylic resin and then polished, and depths were delimited. Microhardness tests were performed on cervical, middle, and occlusal enamel pre- and post-radiotherapy with a load of 50g for 30s...
