BACKGROUND: Autophagy and neutrophil extracellular DNA traps (NETs) are implicated in asthma; however, their roles in asthma pathogenesis have not been elucidated. OBJECTIVES: We compared autophagy and NET production levels from peripheral blood neutrophils (PBNs) of patients with severe asthma (SA) and non-severe asthma (NSA). Additionally, we investigated the inflammatory effects of NETs on human airway epithelial cells (AECs) and peripheral blood eosinophils (PBEs)...

The National Aeronautics and Space Administration (NASA) measures and validates the biological cleanliness of spacecraft surfaces by counting endospores using the NASA standard assay (NSA). NASA has also approved an adenosine-5'-triphosphate (ATP)-based detection methodology as a means to prescreen surfaces for the presence of microbial contamination, prior to the spore assay. During Mars Science Laboratory (MSL) spacecraft assembly, test, and launch operations, 4853 surface samples were collected to verify compliance with the bioburden requirement at launch...

Neuronal surface antibodies (NSA) involved in autoimmune encephalitis (AE) have been related to relapses in HVS encephalitis. Their role in non-encephalitic psychosis is controversial. We previously reported an HIV-infected patient, NSA-positive, only presenting psychosis. Therefore, we determined the NSA prevalence in a prospective cohort of 22 HIV-positive patients with psychosis and we analyzed the frequency of HIV infection among NSA tested patients due to AE suspicion. We found no NSA in the prospective cohort...

Tuberous sclerosis complex (TSC) is a genetic multi-organ disorder characterized by the development of neoplastic lesions in kidney, lung, brain, heart and skin. It is caused by an inactivating mutation in tumor suppressor genes coding the TSC1/TSC2 complex, resulting in hyperactivation of mTOR- and Raf/MEK/MAPK-dependent signaling that stimulates tumor cell proliferation and metastasis. Despite its oncogenic effect, cells with TSC deficiency were more sensitive to oxidative stress and dependent on mitochondrial metabolism, providing a rationale for a new therapeutic approach...

A new downy mildew resistance gene, Pl 19 , was identified from wild Helianthus annuus accession PI 435414, introduced to confection sunflower, and genetically mapped to linkage group 4 of the sunflower genome. Wild Helianthus annuus accession PI 435414 exhibited resistance to downy mildew, which is one of the most destructive diseases to sunflower production globally. Evaluation of the 140 BC1F2:3 families derived from the cross of CMS CONFSCLB1 and PI 435414 against Plasmopara halstedii race 734 revealed that a single dominant gene controls downy mildew resistance in the population...

Elastography provides tissue mechanical information to differentiate normal and disease states. Nowadays, axial displacement and strain are usually estimated in clinical practice whereas lateral estimation is rarely used given that its accuracy is typically one order of magnitude worse than that of axial estimation. To improve the performance of lateral estimation, spatial angular compounding of multiple axial displacements along ultrasound beams transmitting in different steering angles was previously proposed...

Individual differences in early attention are associated with later social, cognitive, and emotional development, and attentional deficits in the first year are associated with risk for developmental disorders such as Autism Spectrum Disorder (ASD). The First Year Inventory (FYI; Baranek, Watson, Crais, & Reznick, 2003) was developed to identify 12-month-olds at risk for an ASD diagnosis. The current study identifies FYI items that reflect aspects of early attention that might predict future typical and atypical social, cognitive, and emotional development...

BACKGROUND: Given potential safety risks when admitting injured patients to nonsurgical services (NSS), the American College of Surgeons mandates trauma centers justification. However, evidence supporting this requirement is lacking. METHODS: Adult patients cleared for admission to a NSS at a level 1 trauma center between 2012 and 2014 were retrospectively reviewed. Patient demographic, injury, and outcome characteristics were compared between nonsurgical (NSA) and surgical admission patients and analyzed for predictive value...

High operational and maintenance costs represent as major economic constraints in the wind turbine (WT) industry. These concerns have made investigation into fault diagnosis of WT systems an extremely important and active area of research. In this paper, an immune system (IS) inspired methodology for performing fault detection and isolation (FDI) of a WT system is proposed and developed. The proposed scheme is based on a self nonself discrimination paradigm of a biological IS. Specifically, the negative selection mechanism [negative selection algorithm (NSA)] of the human body is utilized...

INTRODUCTION: The Variable angle Martin Plate (MP) is designed to offer patient-specific adaption for the treatment of intertrochanteric hip fractures. Its proposed benefits include optimization of lag screw placement, plate shaft congruence and reduced risk of failure. Often its use has been criticized as representing a poor reduction of the fracture. The purpose of this study was to assess for a poorer quality of reduction, and compare functional outcomes and mortality, using a MP to that of a fixed angle Dynamic Hip Screw (DHS) in a matched cohort of patients...
