Genome sequences from over 200 plant species have already been published, with this number expected to increase rapidly due to advances in sequencing technologies. Once a new genome has been assembled and the genes identified, the functional annotation of their proteins using ontologies is of key importance as it places the sequencing data in a biological context. Furthermore, in order to keep pace with rapid production of genome sequences, this functional annotation process must be fully automated. Here we present a redesigned and significantly enhanced MapMan4 framework, together with a revised version of the associated online Mercator annotation tool...

BACKGROUND: The clinical interest of using bubble humidification of oxygen remains controversial. This study was designed to further explore whether delivering dry oxygen instead of bubble-moistened oxygen had an impact on discomfort of ICU patients. METHODS: This randomized multicenter non-inferiority open trial included patients admitted in intensive care unit and receiving oxygen. Any patient receiving non-humidified oxygen (between 0 and 15 L/min) for less than 2 h could participate in the study...

The aim of this work was to analyse the distribution of causal and candidate mutations associated to relevant productive traits in twenty local European pig breeds. Also, the potential of the SNP panel employed for elucidating the genetic structure and relationships among breeds was evaluated. Most relevant genes and mutations associated with pig morphological, productive, meat quality, reproductive and disease resistance traits were prioritized and analyzed in a maximum of 47 blood samples from each of the breeds (Alentejana, Apulo-Calabrese, Basque, Bísara, Majorcan Black, Black Slavonian (Crna slavonska), Casertana, Cinta Senese, Gascon, Iberian, Krškopolje (Krškopoljski), Lithuanian indigenous wattle, Lithuanian White Old Type, Mora Romagnola, Moravka, Nero Siciliano, Sarda, Schwäbisch-Hällisches Schwein (Swabian Hall pig), Swallow-Bellied Mangalitsa and Turopolje)...

Rationale Guidelines recommend that end-tidal CO2 (EtCO2) should be used to monitor cardiopulmonary resuscitation (CPR) but its physiological interpretation remains uncertain. Chest compressions induce oscillations in expired CO2, which could reflect variable degrees of intrathoracic airway closure. Objectives To understand the capnogram during CPR and analyze its relationship with airway patency and delivered ventilation. Methods, Measurements 1) Clinical study analyzing capnogram patterns after intubation in patients with out-of-hospital cardiac arrest receiving continuous chest compressions...

The epithelium of the intestinal mucosa and the gut-associated lymphoid tissues (GALT) constitute an essential physical and immunological barrier against pathogens. In order to study the specificities of the GALT transcriptome in pigs, we compared the transcriptome profiles of jejunal and ileal Peyer's patches (PPs), mesenteric lymph nodes (MLNs) and peripheral blood (PB) of four male piglets by RNA-Seq. We identified 1,103 differentially expressed (DE) genes between ileal PPs (IPPs) and jejunal PPs (JPPs), and six times more DE genes between PPs and MLNs...

BACKGROUND: The efficacy of venovenous extracorporeal membrane oxygenation (ECMO) in patients with severe acute respiratory distress syndrome (ARDS) remains controversial. METHODS: In an international clinical trial, we randomly assigned patients with very severe ARDS, as indicated by one of three criteria - a ratio of partial pressure of arterial oxygen (Pao2 ) to the fraction of inspired oxygen (Fio2 ) of less than 50 mm Hg for more than 3 hours; a Pao2 :Fio2 of less than 80 mm Hg for more than 6 hours; or an arterial blood pH of less than 7...

Full-horizon cylindrical projections of the optic array are in common use. One wonders whether the public actually profits from such pictorial information, since the space behind one's back does not exist in visual awareness. In an experiment, a test image included six persons located at the corners of an irregular hexagon centred at the camera. Two persons faced the camera, two turned their back to the camera and two others faced a direction at right angles to the camera. The distances to the camera were unequal and varied from 1 to 2 m...

The benefit of early admission of allogeneic stem cell transplantation (SCT) recipients to the intensive care unit (ICU) as soon as they develop organ injury is unknown. We performed a retrospective study on 92 patients admitted to the ICU to determine the impact of time from organ injury to ICU admission on outcome. The number of organ injuries prior to ICU admission was associated with an increased in-hospital mortality (OR 1.7, 95% CI 1-2.7, p = 0.04). Time between first organ injury and ICU admission was also associated with an increased in-hospital survival (OR 1...

Nanotemplates derived from the self-assembly of AB-type block copolymers provide an elegant route to achieve well-defined metallic dot arrays, even if the variety of pattern symmetries is restricted due to the limited number of structures offered by microphase separated diblock copolymers. A strategy that relies on the use of complex network structures accessible through the self-assembly of linear ABC-type terpolymers is presented for the formation of metallic nanodots arrays with "outside-the-box" symmetries...

BACKGROUND: Studying ventilation and intrathoracic pressure (ITP) induced by chest compressions (CC) during Cardio Pulmonary Resuscitation is challenging and important aspects such as airway closure have been mostly ignored. We hypothesized that Thiel Embalmed Cadavers could constitute an appropriate model. METHODS: We assessed respiratory mechanics and ITP during CC in 11 cadavers, and we compared it to measurements obtained in 9 out-of-hospital cardiac arrest patients and to predicted values from a bench model...

OBJECTIVES: To report outcomes of immunocompromised patients treated with extracorporeal membrane oxygenation (ECMO) for severe acute respiratory distress syndrome (ARDS) and to identify their pre-ECMO predictors of 6-month mortality and main ECMO-related complications. METHODS: Retrospective multicenter study in 10 international intensive care units (ICUs) with high ECMO-case volumes. Immunocompromised patients, defined as having hematological malignancies, active solid tumor, solid-organ transplant, acquired immunodeficiency syndrome, or long-term or high-dose corticosteroid or immunosuppressant use, and severe ECMO-treated ARDS from 2008 to 2015 were included Measurements and Main Results: We collected demographics, clinical, ECMO-related complications, ICU- and 6-month-outcome data for 203 patients (median APACHE II 28 [25th ;75th percentile, 20;33]; age 51 [38;59] years, PaO2/FiO2 60 [50;82] mmHg before ECMO) who fulfilled our inclusion criteria...

INTRODUCTION: While prone positioning (PP) has been shown to improve patient survival in moderate to severe acute respiratory distress syndrome (ARDS) patients, the rate of application of PP in clinical practice still appears low. AIM: This study aimed to determine the prevalence of use of PP in ARDS patients (primary endpoint), the physiological effects of PP, and the reasons for not using it (secondary endpoints). METHODS: The APRONET study was a prospective international 1-day prevalence study performed four times in April, July, and October 2016 and January 2017...

PURPOSE OF REVIEW: Despite major improvement in ventilation strategies, hospital mortality and morbidity of the acute respiratory distress syndrome (ARDS) remain high. A lot of therapies have been shown to be ineffective for established ARDS. There is a growing interest in strategies aiming at avoiding development and progression of ARDS. RECENT FINDINGS: Recent advances in this field have explored identification of patients at high-risk, nonspecific measures to limit the risks of inflammation, infection and fluid overload, prevention strategies of ventilator-induced lung injury and patient self-inflicted lung injury, and pharmacological treatments...

Ozone is a highly oxidizing gas with insecticidal activity and it is a potential alternative to conventional fumigants, such as phosphine and methyl bromide, for managing stored product insects. Susceptibility of the merchant grain beetle, Oryzaephilus mercator (Fauvel; Coleoptera: Silvanidae), an important pest of stored products, to ozone treatments is unknown. In this study, we investigated the efficacy of ozone for controlling O. mercator. We determined concentration-mortality relationships for all stages of O...

BACKGROUND: Acute respiratory distress syndrome (ARDS) results in vascular leakage, inflammation and respiratory failure. There are currently no approved pharmacological treatments for ARDS and standard of care involves treatment of the underlying cause, and supportive care. The vascular leakage may be related to reduced concentrations of local adenosine, which is involved in maintaining endothelial barrier function. Interferon (IFN) beta-1a up-regulates the cell surface ecto-5'-nucleotidase cluster of differentiation 73 (CD73), which increases adenosine levels, and IFN beta-1 may, therefore, be a potential treatment for ARDS...
