PI3K signaling and lysyl oxidase is critical to corneal stroma fibrosis following mustard gas injury.

Sulfur mustard gas (SM), an alkylating and vesicating agent, has been used frequently in many wars and conflicts. SM exposure to the eye results in several corneal abnormalities including scar/fibrosis formation. However, molecular mechanism for SM induced corneal fibrosis development is poorly understood.

Subsistence swine farming: seroprevalence and risk factors associated with Lawsonia intracellularis infection in the state of Minas Gerais Brazil in 2016.

Although it is considered an economically relevant and prevalent disease, little information is available on the epidemiology and risk factors of porcine proliferative enteropathy (PPE) in commercial pigs, and no publication is available on subsistence pig farming. The objectives of this study were to estimate the seroprevalence of L. intracellularis and identify associated risk factors in backyard pigs in the 12 mesoregions of the state of Minas Gerais, Brazil.

Synergic Effect of and Coinfection: Anatomopathological and Microbiome Evaluation.

and coinfection has been observed in the diagnostic routine; however, no studies have evaluated their interaction. This study aimed to characterize lesions and possible synergisms in experimentally infected pigs. Four groups of piglets, coinfection (CO), (BRA), (LAW), and negative control (NEG), were used.

Experimental Infection of Pigs with a ST 245 Isolated from an Asymptomatic Pig in a Herd with No History of Swine Dysentery.

Swine dysentery (SD) is characterized by a severe mucohemorrhagic colitis caused by infection with species. In infected herds the disease causes considerable financial loss due to mortality, slow growth rates, poor feed conversion, and costs of treatment. is the most common etiological agent of SD and infection is usually associated with disease.

Protocol for detecting unrecognized sleep apnea in patients with atrial fibrillation by a home-monitoring device: the DAN-APNO study.

Background: Determining the presence of modifiable risk factors for atrial fibrillation (AF), such as sleep apnea is of clinical importance due to the potential impact targeting these risk factors can have on the progression and burden of AF. Using new digital-based technology is a promising solution to the underreporting of sleep apnea highlighted by academical societies in recent years. The aim of this study is to report the prevalence and severity of sleep apnea in patients with AF and, secondarily, assess the accuracy and feasibility of a new home-screening device for sleep apnea (NightOwl™ by Ectosense).

The level of representation of irrelevant stimuli-Distractor-response binding within and between the senses.

Binding theories assume that features of stimuli and executed responses can be integrated together in one event file (Hommel, Visual Cognition, 5, 183-216, 1998; Hommel, Cognitive Sciences, 8, 494-500, 2004). Every reencounter with one or more of the stored features leads to an automatic retrieval of the previously constructed event file and hence of the response-even the repetition of a task-irrelevant distractor stimulus can retrieve a previously encoded response. This so-called distractor-response binding effect is typically investigated using a sequential prime-probe design that allows the orthogonal variation of response relation (response repetition vs.

Brightness versus darkness: The influence of stimulus intensity on the distractor-response binding effect.

The intensity of a stimulus has been found to have a distinct impact upon response processes (e.g., response speed, response force, & response selection).

Survival of Lawsonia intracellularis in porcine peripheral blood monocyte-derived macrophages.

Lawsonia intracellularis, an obligately intracellular enteric bacterium, infects intestinal epithelial cells, but may also be found within macrophages in the intestinal lamina propria of affected pigs. Macrophages play an important role in host defense against infectious agents, but the role of this cell in L. intracellularis infection is not well understood.

Why star retrieves scar: Binding and retrieval of perceptual distractor features.

If a target stimulus is presented together with a response-irrelevant distractor stimulus, both stimuli can be encoded together with the response in an event file (see Hommel, 2004). The repetition of any feature of such an event-file can then retrieve the previously encoded response. This kind of feature-based retrieval is an important mechanism in action control.

Eosinophil-guided corticosteroid therapy in patients admitted to hospital with COPD exacerbation (CORTICO-COP): a multicentre, randomised, controlled, open-label, non-inferiority trial.

Background: Treatment with systemic corticosteroids in patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) is associated with debilitating adverse effects. Therefore, strategies to reduce systemic corticosteroid exposure are urgently required and might be offered by a personalised biomarker-guided approach to treatment. The aim of this study was to determine whether an algorithm based on blood eosinophil counts could safely reduce systemic corticosteroid exposure in patients admitted to hospital with acute exacerbations of COPD.

Oral fluid for detection of exposure to Lawsonia intracellularis in naturally infected pigs.

To demonstrate the utility of oral fluid (OF) for indirect diagnostic detection of Lawsonia intracellularis (Li), 15 pig farms were studied. Serum and fecal samples were collected from 20 animals from five different age groups on each farm. OF samples were collected from animals in two pens of the same age groups.

Distractor-based retrieval in action control: the influence of encoding specificity.

If a target stimulus is presented together with a response irrelevant distractor stimulus, both stimuli can be encoded together with the response in an event file [see Hommel (Trends Cogn Sci 8:494-500, 2004)]. The repetition of the distractor can retrieve the encoded response. This kind of distractor-based retrieval is an important mechanism in action control.

Dissecting stimulus-response binding effects: Grouping by color separately impacts integration and retrieval processes.

In selection tasks, target and distractor features can be encoded together with the response into the same short-lived memory trace, or event file (see Hommel, 2004), leading to bindings between stimulus and response features. The repetition of a stored target or distractor feature can lead to the retrieval of the entire episode, including the response-so-called "binding effects." Binding effects due to distractor repetition are stronger for grouped than for nongrouped target and distractor stimulus configurations.

Disentangling inhibition-based and retrieval-based aftereffects of distractors: Cognitive versus motor processes.

Selective attention refers to the ability to selectively act upon relevant information at the expense of irrelevant information. Yet, in many experimental tasks, what happens to the representation of the irrelevant information is still debated. Typically, 2 approaches to distractor processing have been suggested, namely distractor inhibition and distractor-based retrieval.

A multi-center randomized, controlled, open-label trial evaluating the effects of eosinophil-guided corticosteroid-sparing therapy in hospitalised patients with COPD exacerbations - The CORTICO steroid reduction in COPD (CORTICO-COP) study protocol.

Background: The most commonly applied treatment for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) is a 5-day course of high-dose systemic corticosteroids. However, this treatment has not been shown to reduce mortality and can potentially have serious side effects. Recent research has shown that, presumably, only a subgroup of COPD patients identifieable by blood eosinophil count benefit from a rescue course of prednisolone.

A Sleep Position Trainer for positional sleep apnea: a randomized, controlled trial.

We tested the effect of the Sleep Position Trainer, a vibrational device, for positional sleep apnea in an open, randomized controlled trial with 101 patients, where 52 patients were allocated to Sleep Position Trainer and 49 patients to a non-treatment control group for 2 months (Part 1). All patients were then followed as a cohort for a period of 6 months with use of the Sleep Position Trainer (Part 2). The participants were assessed with polygraphy at entry, and after 2 and 6 months.

Routine examination for tuberculosis is still indicated during bronchoscopy for pulmonary infiltrates.

Introduction: Tuberculosis (TB) can present in numerous ways and can be radiological indistinguishable from cancer. In several guidelines for bronchoscopy (FOB) in low-incidence areas, a Mycobacterium tuberculosis test is only recommended when TB is clinically suspected. Due to the expenses associated with M.

Evaluation of the decision support system for antimicrobial treatment, TREAT, in an acute medical ward of a university hospital.

Objectives: TREAT, a decision support system for antimicrobial therapy, was implemented in an acute medical ward.

Methods: Patients admitted on suspicion of infection were included in the study. The evaluation of TREAT was done both retrospectively and prospectively.

Visualizing inflammation activity in rheumatoid arthritis with Tc-99 m anti-CD4-mAb fragment scintigraphy.

Purpose: T-cell-located CD4 antigen represents one of the therapeutic targets in rheumatoid arthritis (RA). However, up to now there is no established imaging tool to visualize this target in vivo. The aim of our study was to assess the safety and tolerability of a technetium-99m labelled murine anti-human CD4 IgG1-Fab fragment ([(99m)Tc]-anti-CD4-Fab, [(99m)Tc]-EP1645) in patients with active synovitis due to RA, and to evaluate its potential as a marker of disease activity.

Pneumococcal antibody levels in children with PID receiving immunoglobulin.

Objectives: Clinical data are lacking on optimal levels of specific antipneumococcal antibodies (PnPsAbs) in patients with primary immunodeficiency (PID) receiving intravenous immunoglobulin (IVIG) replacement. Objectives were to conduct a prospective multicenter study providing data on total immunoglobulin G (IgG) and peak/trough levels of PnPsAbs specifically targeting the 16 most prevalent pneumococcal serotypes in IVIG-treated children with PID; to compare trough PnPsAb levels with those measured in healthy adults and the IVIG product; and to evaluate PnPsAb protection correlates with thresholds based on World Health Organization.

Methods: Patients received 7 consecutive IVIG infusions.

Clinical consequences of using PNA-FISH in Staphylococcal bacteraemia.

To optimize patient treatment and rational use of antimicrobials, it is important to provide fast information on findings in blood-cultures (BCs). The purpose of this study was to evaluate the impact of using peptide nucleic acid fluorescence in situ hybridization (PNA-FISH) on positive BCs containing Gram-positive cocci in clusters to differentiate between Staphylococcus aureus (SA) and coagulase negative staphylococci (CoNS) on the prescribed antimicrobial therapy and on the number of contacts between microbiologist and clinician. All cases of positive BCs in our laboratory with SA or CoNS in the year 2011 were identified and the charts were reviewed retrospectively.

Stability of therapeutic albumin solutions used for molecular adsorbent recirculating system-based liver dialysis.

Mounting evidence suggests beneficial effects of albumin dialysis-based liver support in patients suffering from acute-on-chronic liver failure. Molecular adsorbent recirculating system (MARS) is a nonbiological liver support device, based on the exchange of albumin-bound toxins between the patient's blood and a 20% human serum albumin solution in a secondary circuit. Bound toxins are continuously removed from the circulating albumin by exposure to activated charcoal and an ion-exchange resin.

Specific protein content of pools of plasma for fractionation from different sources: impact of frequency of donations.

Background And Objectives: Plasma pools for the production of human plasma medicinal products are distinguished according to the collection method (recovered or apheresis plasma) and the donor remuneration status. National regulations and the physical status of the donor determine the donation frequency and plasma volume per session. Relevant protein contents of different types of pools have not fully been compared.

Complementary strategies to elucidate T helper cell epitopes in myasthenia gravis.

CD4(+) T cells specific for the acetylcholine receptor (AChR) are assumed to play an important role in pathogenesis of myasthenia gravis (MG). A large and diverse number of potential T cell epitopes have been reported for different experimental setups aiming at the identification of disease-relevant T cells in MG. Investigating the T cell response to the epsilon subunit of human AChR, we explore complementary in vitro and in vivo approaches (PBMC from MG patients and mice transgenic for HLA-DR3 and human CD4) to address the possibilities and limitations of different strategies for elucidating natural autoimmune T cell epitopes.
