The reported preferred host of O. nubilalis is corn, Zea mays L. (Cyperales Poaceae), although it is considered to be a generalist agricultural pest. Life cycles of the two pheromone races, E and Z, align with the seasonality of different agricultural plants. Since the introduction of Bt corn in 1996, overall O. nubilalis presence has declined and suggests that alternative crop plants might not be suitable hosts. We investigated plant vegetation preference of third-instar Z-race O. nubilalis for leaf disks of corn and a variety of other crops using 48 h no-choice and choice tests. Z-race larvae gained more mass on V6 non-Bt field corn leaf disks in comparison to other plant species options. Additionally, a preference for non-Bt field corn leaf disks was observed in most comparisons. Higher consumption of cucumber, Cucumis sativus L. (Cucurbitales Cucurbitaceae), leaf disks as compared to non-Bt field corn leaf disks suggested an ability to feed on excised leaf tissues of a plant species that does not induce defenses to herbivory. © The Author(s) 2020.

SUMMARY ANSWER The overall frequency of major chromosome abnormalities in the entire cohort was 28.2% (2493/8826), with a significant decrease in the detection of major chromosome abnormalities with later developmental stage, from 50.9% to 21.3% to 15.6% of tests in the miscarriage, prenatal and postnatal cohorts, respectively. WHAT IS KNOWN ALREADY Over the past decade, technological advances have revolutionized genomic testing at every stage of reproduction. Chromosomal microarrays (CMAs) are now the gold standard of chromosome assessment in prenatal diagnosis and pediatrics. STUDY DESIGN, SIZE, DURATION A population-based cohort study including all chromosome analysis was performed in the Australian state of Victoria during a 24-month period from January 2015 to December 2016.

While there is concern regarding the abuse of illegal opioids, overdose is also strongly associated with prescription opioids. The Centers for Disease Control and Prevention supports coprescribing of naloxone with opioids; however, a review of naloxone prescriptions recorded within a primary care group indicated limited use of the reversal agent. METHODS Through the collaboration of pharmacy and information services personnel, a report was created to identify all patients receiving chronic opioid therapy. To assess the risk of overdose, a validated risk scoring method was used. If patients were determined to be at high risk for overdose, outreach by a clinical pharmacist was conducted to educate them on the benefits of naloxone. For patients agreeable to receiving naloxone, prescriptions were entered into the electronic health record for primary care provider (PCP) verification. Contact was made following order verification to ensure patient ue. The pharmacy-driven approach highlighted the importance of having pharmacists within an ambulatory care setting and allowed high-level pharmacist practice without adding to the workload of other members of the healthcare team. © American Society of Health-System Pharmacists 2020.

METHODS The labeling of the 100 most commonly used injectable medications in the adult ICUs of an academic medical center in Arizona were evaluated. Any information related to adult weight-based dosing, weight descriptors, dosing of patients at extremes of weight (body mass index of 40 kg/m2), and dosing of patients receiving hemodialysis, CRRT, or ECMO was extracted from Food and Drug Administration-approved product labeling. Information was ranked for dosing usefulness on a scale of 0 to 3; an information usefulness score of 2 or greater was considered minimally adequate for dosing special ICU populations.

Contemporary information about the types of infections, causative pathogens, and outcomes can aid the development of policies for prevention, diagnosis, treatment, and resource allocation and may assist in the design of interventional studies. Objective To provide information about the prevalence and outcomes of infection and the available resources in ICUs worldwide. Design, Setting, and Participants Observational 24-hour point prevalence study with longitudinal follow-up at 1150 centers in 88 countries. All adult patients (aged ≥18 years) treated at a participating ICU during a 24-hour period commencing at 0800 on September 13, 2017, were included. The final follow-up date was November 13, 2017. Exposures Infection diagnosis and receipt of antibiotics. Main Outcomes and Measures Prevalence of infection and antibiotic exposure (cross-sectional design) and all-cause in-hospital mortality (longitudinal design). Results Among 15 2.10-1.60]; P = .003). Among antibiotic-resistant microorganisms, infection with vancomycin-resistant Enterococcus (OR, 2.41 [95% CI, 1.43-4.06]; P = .001), Klebsiella resistant to β-lactam antibiotics, including third-generation cephalosporins and carbapenems (OR, 1.29 [95% CI, 1.02-1.63]; P = .03), or carbapenem-resistant Acinetobacter species (OR, 1.40 [95% CI, 1.08-1.81]; P = .01) was independently associated with a higher risk of death vs infection with another microorganism. Conclusions and Relevance In a worldwide sample of patients admitted to ICUs in September 2017, the prevalence of suspected or proven infection was high, with a substantial risk of in-hospital mortality.We report the identification and characterization of a bacteriophage λ-encoded protein, NinH. Sequence homology suggests similarity between NinH and Fis, a bacterial nucleoid-associated protein involved in numerous DNA topology manipulations, including chromosome condensation, transcriptional regulation and phage site-specific recombination. We find that NinH functions as a homodimer and is able to bind and bend double-stranded DNA in vitro. Furthermore, NinH shows a preference for a 15 bp signature sequence related to the degenerate consensus favored by Fis. Structural studies reinforced the proposed similarity to Fis and supported identification of residues involved in DNA binding which were demonstrated experimentally. Overexpression of NinH proved toxic and this correlated with its capacity to associate with DNA. NinH is the first example of a phage-encoded Fis-like nucleoid-associated protein that likely influences phage excision-integration reactions or bacterial gene expression.

Uprosertib cost While an overactive complement system has been linked to pathogenesis, mechanisms contributing to its activation are largely unknown. In aged and AMD eyes, loss of the elastin layer (EL) of Bruch's membrane (BrM) has been reported. Elastin antibodies are elevated in patients with AMD, the pathogenic significance of which is unclear. Here we assess the role of elastin antibodies using a mouse model of smoke-induced ocular pathology (SIOP), which similarly demonstrates EL loss. Methods C57BL/6J mice were immunized with elastin or elastin peptide oxidatively modified by cigarette smoke (ox-elastin). Mice were then exposed to cigarette smoke or air for 6 months. Visual function was assessed by optokinetic response, retinal morphology by spectral-domain optical coherence tomography and electron microscopy, and complement activation and antibody deposition by Western blot. Results Ox-elastin IgG and IgM antibodies were elevated in ox-elastin immunized mice following 6 months of smoke, whereas elastin immunization had a smaller effect. Ox-elastin immunization exacerbated smoke-induced vision loss, with thicker BrM and more damaged retinal pigment epithelium (RPE) mitochondria compared with mice immunized with elastin or nonimmunized controls. These changes were correlated with increased levels of IgM, IgG2, IgG3, and complement activation products in RPE/choroid. Conclusions These data demonstrate that SIOP mice generate elastin-specific antibodies and that immunization with ox-elastin exacerbates ocular pathology. Elastin antibodies represented complement fixing isotypes that, together with the increased presence of complement activation seen in immunized mice, suggest that elastin antibodies exert pathogenic effects through mediating complement activation.Purpose Although stem cell activity represents a crucial feature in corneal and ocular surface homeostasis, other cells populating this region and the neighboring zones might participate and influence local microenvironment. Mast cells, the long-lived and tissue-sited immune cells, have been previously reported in corneoscleral specimens. Herein, mast cells were investigated in corneoscleral tissues and related to microenvironment protein expression. Methods Twenty-six (14 male/12 female; older than 60 years) human corneoscleral specimens were sectioned for light and fluorescent immunostaining (CD45, p63, Ck-3/7/12/19, tryptase/AA1, and chymase/CC1). Corneal, limbal, and conjunctival squares were produced for molecular and biochemical analysis. Statistical comparisons were carried out by ANOVA. Results Toluidine blue staining identified metachromatic intact or degranulated mast cells in the area below the palisades' Vogt (Ck-3/12-positive epithelium and underneath p63 immunoreactivity). Tryptase immunoreactivity was observed close to palisades' Vogt, whereas no specific signal was detected for chymase. Tryptase/AA1 transcripts were quantified in limbal and conjunctival RNA extracts, whereas no specific amplification was detected in corneal ones. Few mediators were overexpressed in limbal extracts with respect to corneal (Neural cell adhesion molecule (NCAM), Intercellular adhesion molecule 3 (ICAM3), Brain-derived Neurotrophic factor (BDNF), and neurotrophin 3 (NT3); P 0.05). Conclusions The specific observation of tryptase phenotype and the interesting protein signature of microenvironment (adhesion molecules, growth factors, and neurotrophins), known to partake mast cell behavior, at least in other areas, would provide additional information to better understand this crucial zone in the framework of ocular surface healthiness.
