Apathy is a mental state of diminished motivation. Although the reward system as the foundation of the motivation in the human brain has been studied extensively with neuroimaging techniques, the electrophysiological correlates of motivation and apathy have not been fully explored. Thus, in 14 healthy volunteers, we examined whether event-related evoked potentials (ERP) obtained during a simple number discrimination task with/without rewards reflected apathy tendency and a reward-dependent tendency, which were assessed separately using the apathy scale and the temperament and character inventory (TCI)...

Up to now, the mechanism of motor impairment and recovery after stroke has been thought to be based on the interhemispheric competition model. According to this model, which assumes that suppressing the excitability of contralesional hemisphere will enhance recovery by reducing transcallosal inhibition (TCI) of the stroke hemisphere, many clinical trials used non-invasive brain stimulation to improve motor function. Despite some positive findings, meta-analysis shows an important source of variability in the results, questioning whether the interhemispheric competition model would be exhaustive enough to explain the positive results or whether other mechanisms could explain the motor effects of inhibitory stimulation in the contralesional hemisphere...

Background: Trypanosoma cruzi causes Chagas disease in the Americas. Outcome of infection ranges from lifelong asymptomatic status to severe disease. Understanding how history of T. cruzi lineage (TcI-TcVI) infection relates to clinical prognosis is challenging. We previously described peptide-based lineage-specific ELISA with Trypomastigote Small Surface Antigen (TSSA). Methods: A novel rapid diagnostic test (Chagas Sero K-SeT) incorporating a peptide corresponding to the TSSA-II/V/VI common epitope was developed, and validated by comparison with ELISA...

PURPOSE OF REVIEW: Some personality traits seem to be associated with obesity, but there is little information available regarding their association with obesity treatment outcomes. The aim of this systematic review was therefore to assess the associations between personality traits-evaluated by means of the Temperament and Character Inventory (TCI)-and outcomes of obesity treatment, including attrition, weight loss, and weight loss maintenance. The PubMed database was searched, and studies were screened as per the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines, and data were collated using a narrative approach...

microRNA-1 (miR-1) is a well-studied conservative microRNA (miRNA) involved in immune responses in mammals and insects. However, little is known about its role in pesticide resistance in arthropods. In this study, we found that a microRNA belong to miR-1 family (tci-miR-1-3p) was significantly down-regulated in a cyflumetofen-resistant strain (CYR) of Tetranychus cinnabarinus compared with its homologous susceptible strain (SS), indicating an involvement of miR-1 in cyflumetofen resistance in mites. One glutathione S-transferase (GST) gene (TCGSTM4, a mu class GST gene), a candidate target gene of tci-miR-1-3p, was found to be significantly down-regulated when tci-miR-1-3p was over-expressed...

The Teladorsagia circumcincta P-glycoprotein-9 (Tci-pgp-9) gene has previously been implicated in multiple-anthelmintic resistance in this parasite. Here we further characterise genetic diversity in Tci-pgp-9 and its possible role in ivermectin (IVM) and multi-drug resistance using two UK field isolates of T. circumcincta, one susceptible to anthelmintics (MTci2) and the other resistant to most available anthelmintics including IVM (MTci5). A comparison of full-length Tci-pgp-9 cDNA transcripts from the MTci2 and MTci5 isolates (∼3...

Achalasia is a motility disorder of the esophagus that might be secondary to a chronic Trypanosoma cruzi infection. Several studies have investigated esophageal achalasia in patients with Chagas disease (CD) in Latin America, but no related studies have been performed in Colombia. The goals of the present study were to determine the presence of anti-T. cruzi antibodies in patients with esophageal achalasia who visited a referral hospital in Bogotá, Colombia, and to detect the presence of the parasite and its discrete typing units (DTUs)...

Purpose: Cough on anesthetic emergence should be prevented considering its dangerous complications. Target-controlled infusion (TCI) of remifentanil can reduce emergence cough effectively, and sex-related differences in effect-site concentration (Ce) of remifentanil have been evaluated in young patients. In this study, we determined the Ce of remifentanil for preventing emergence cough following extubation in male and female elderly patients and evaluated the sex-related difference. Patients and methods: Twenty-three male and 22 female elderly patients aged between 60 and 75 years were enrolled...

Background: Endotracheal intubation during anesthesia induction may increase airway resistance (Raw) and decrease dynamic lung compliance (Cdyn). We hypothesized that prophylactic treatment with a transdermal β2-agonist tulobuterol patch (TP) would help to reduce the risk of bronchospasm after placement of the endotracheal tube. Methods: Eighty-two American Society of Anesthesiologists (ASA) category I or II adult patients showing obstructive patterns were divided randomly into a control and a TP group (n = 41 each)...

Several bat species can be infected by trypanosomes, but there is not much information about which of these parasites infect bats from Triângulo Mineiro and Alto Paranaíba, Minas Gerais state, Brazil, a formerly endemic region for Trypanosoma cruzi, the causative agent of Chagas disease. The aim of this study was to describe, characterize, and identify the presence of trypanosomes in bats. The captured bats (448) belong to four families and to 19 different species. Of those, 37 bats were found to be positive for trypanosomes by microhematocrit, (infection rate 8...

Car ownership in China reached 194 million vehicles at the end of 2016. The traffic congestion index (TCI) exceeds 2.0 during rush hour in some cities. Inefficient processing for minor traffic accidents is considered to be one of the leading causes for road traffic jams. Meanwhile, the process after an accident is quite troublesome. The main reason is that it is almost always impossible to get the complete chain of evidence when the accident happens. Accordingly, a police and insurance joint management system is developed which is based on high precision BeiDou Navigation Satellite System (BDS)/Global Positioning System (GPS) positioning to process traffic accidents...

The aim of this study was to determine the relationship, precision, and bias of a propofol target-controlled infusion (TCI) system during prolonged infusion in neurosurgical patients. We retrospectively included patients undergoing general anesthesia for elective neurosurgical removal of brain tumors and postoperative sedation in the intensive care unit over a period of 3 months. TCI of propofol (Diprifusor - Marsh model) and remifentanil were used for general anesthesia and sedation. We compared propofol blood concentration (Cmeas ) measured by liquid chromatography-mass spectroscopy with predicted concentrations (Cpred ) by the TCI system at 40 minutes (T0), 2 hours (T1), and 4 hours (T2) and every 8 hours after starting the drug infusion and at the time of emergence from sedation...

Chagas disease affects between six and seven million people. Its etiological agent, Trypanosoma cruzi, is classified into six discrete typing units (DTUs). The biological study of 11 T. cruzi strains presented here included four parameters: growth kinetics, parasitemia curves, rate of macrophage infection, and serology to evaluate IgM, total IgG, IgG1, IgG2a, and IgG3. Sequencing of small subunit of ribosomal RNA (SSU rRNA)was performed and the T. cruzi strains were classified into three DTUs. When their growth in liver infusion tryptose medium was represented in curves, differences among the strains could be noted...

Historically, drugs available for treating atopic dermatitis (AD) have been limited to topical corticosteroids (TCS) and topical calcineurin inhibitors (TCI), with systemic immunosuppressants and phototherapy reserved for severe AD. Despite their efficacy, with long term use, these agents have associated safety concerns and limitations. More targeted options with fewer systemic and cutaneous side effects are needed for treating atopic dermatitis. Phosphodiesterase 4 is involved in the regulation of proinflammatory cytokines via the degradation of cAMP...

Droughts cause huge losses of society and environment, therefore it is important to study the spatial-temporal pattern of drought. The traditional remote sensing drought indices (AVI, VCI and TCI) only consider the single factor representing the soil moisture (surface temperature or NDVI). The comprehensive remote sensing drought indices (VSWI and TVDI) can estimate the soil moisture more accurately, but they are not suitable for large scale region especially with great elevation variation. In this study, a modified Temperature Vegetation Drought Index (mTVDI) was constructed based on the correction of elevation and dry edge...
