Rapid detection techniques of pathogenic bacteria in the liquid food supply chain are of significant research interest due to their pivotal role in preventing foodborne outbreaks, and in maintaining high standards of public health and safety. Milk and dairy products are of particular interest due to their widespread consumption across the globe. In this paper, a biosensor for detecting pathogenic bacteria in milk using dextrin-capped gold nanoparticles (d-AuNP) as labels decoded at microwave frequencies is presented...

The application of overtone nuclear magnetic resonance (OT NMR) to symmetric spin transitions of integer quadrupolar nuclei is of considerable interest since this transition is immune to the first-order quadrupolar interaction, thus resulting in narrow NMR lines. Owing to its roles in nature and its high natural abundance, 14 N (I = 1) OT NMR has been explored, in which the indirect and/or direct acquisitions of 14 N OT were experimentally demonstrated. However, other than 14 N nucleus, no OT NMR observation of other integer quadrupolar nuclei has been reported in the literature...

Although botanical trace evidence is often encountered in case investigations, the utilization of such traces in forensic investigations is still limited. Development of a forensic STR system for the two species of Betula (birch) indigenous to and abundant in North West Europe is a step in enhancing the applicability of traces from these species. We describe six microsatellite markers developed for birch species in detail, including repeat structure, and we propose a nomenclature for the encountered alleles...

Identification of all genetic variants associated with complex traits is one of the most important goals in modern human genetics. Genome-wide association studies (GWAS) have been successfully applied to identify common variants, which thus far explain only small portion of heritability. Interests in rare variants have been increasingly growing as an answer for this missing heritability. While next-generation sequencing allows detection of rare variants, its cost is still prohibitively high to sequence a large number of human DNA samples required for rare variant association studies...

Purpose: To understand the effect of aging on microsaccade functions and brain physiologic responses, we quantified microsaccades and their physiologic correlates (including their interaction with alpha band brain oscillation) in normal subjects of different ages. Methods: Twenty-two normally sighted young (18 to 29 years), 22 middle-aged (31 to 55 years), and 22 elderly subjects (56 to 77 years) participated in this cross-sectional study. Dense array EEG and high-resolution eye-tracking data were simultaneously recorded during a fixation task...

BACKGROUND: The 8-aminoquinoline antimalarials, the only drugs which prevent relapse of vivax and ovale malaria (radical cure), cause dose-dependent oxidant haemolysis in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency. Patients with <30% and <70% of normal G6PD activity are not given standard regimens of primaquine and tafenoquine, respectively. Both drugs are currently considered contraindicated in pregnant and lactating women. METHODS: Quantitative G6PD enzyme activity data from 5198 individuals were used to estimate the proportions of heterozygous females who would be ineligible for treatment at the 30% and 70% activity thresholds, and the relationship with the severity of the deficiency...

One of the main aspects affecting the quality of life of people living in urban and suburban areas is the continuous exposure to high road traffic noise (RTN) levels. Nowadays, thanks to Wireless Acoustic Sensor Networks (WASN) noise in Smart Cities has started to be automatically mapped. To obtain a reliable picture of the RTN, those anomalous noise events (ANE) unrelated to road traffic (sirens, horns, people, etc.) should be removed from the noise map computation by means of an Anomalous Noise Event Detector (ANED)...

BACKGROUND: During the past several decades, anesthesia has become increasingly safe. Truly major adverse events are rare, and anesthesia quality researchers have instituted programs to evaluate "near miss" or less critical adverse events to evaluate the safety of anesthesia delivery. In this study, we aimed to evaluate calls for emergency help in our institution as a surrogate for pending critical events. We hypothesized that calls would be more common in patients with high American Society of Anesthesiologists (ASA) physical status, history of prematurity, and children with recent respiratory illness compared to those without these characteristics...

Recent evidence suggests that less frequent repositioning of long-term care residents at moderate to high risk of developing pressure ulcers (PrUs) is noninferior to current repositioning standards in preventing PrUs, but the long-term health and economic consequences of less frequent repositioning have not been adequately estimated. Our objective was to estimate the cost-effectiveness of different repositioning strategies (2-, 3-, 4-hour intervals). We conducted a cost-utility analysis using a lifetime horizon based on data from a randomized clinical trial and the literature...

BACKGROUND: Studies exploring "anticipated regret" concerning alcohol rarely consider the broader consequences of excessive drinking that might be regretted. Even if specific regrettable experiences are identified, interventions targeting them may not succeed because individuals are often optimistic about their risk susceptibility. OBJECTIVES: This study examined the consequences young adult drinkers reported, and the extent to which these were regretted...

About 50% of patients with asthma exhibit chronic airway inflammation driven by the type 2 cytokines interleukin (IL)-4, IL-5, and IL-13. These patients with type 2-high asthma experience more allergic symptoms, greater airway hyperresponsiveness, and more severe mucus obstruction than patients with type 2-low asthma. Mouse models of asthma have shown that much of the airway dysfunction in these models can be generated by IL-13 stimulation of the airway epithelium alone. Both in vivo mouse model studies and in vitro studies of human mucociliary airway epithelial cultures have shown that IL-13 induces cellular remodeling of the airway epithelium through proliferation-independent transdifferentiation processes...

B cell interaction with follicular helper T cells and their subsequent differentiation into high-affinity antibody producing cells normally takes place in secondary lymphoid organs. The costimulator ICOS plays a key role in this process and is therefore considered as an attractive target to modulate exaggerated B cell responses in autoimmune or allergic diseases. Inflamed tissues were recently recognized as additional sites of active T cell/B cell interaction. To analyze whether ICOS costimulation is also important there, we employed a mouse airway inflammation model which allows to directly compare immune reactions in the lung-draining lymph node and the lung tissue and also to assess the relative importance of dendritic cells versus B cells as antigen-presenting cells...

A mechanically adaptable elastomer composite is prepared with reversible soft-stiff properties that can be easily controlled. By the exploitation of different morphological structures of calcium sulphate, which is acting as active filler in soft elastomer matrix, the magnitude of filler reinforcement can be reversibly altered that will be reflected in changes of the final stiffness of the material. The higher stiffness, in other words, the higher modulus of the composites, is realized by the in-situ development of fine nano-structured calcium sulphate di-hydrate crystals, which are formed during exposure to water and, further, this highly reinforcing crystals can be transformed to a non-reinforcing hemi-hydrate mesocrystalline structure by simply heating the system in a controlled way...

There is substantial evidence to support the claim that religion can protect against suicide ideation, suicide attempts, and completed suicide. There is also evidence that religion does not always protect against suicidality. More insight is needed into the relationship between suicidal parameters and dimensions of religion. A total of 155 in- and outpatients with major depression from a Christian Mental Health Care institution were included. The following religious factors were assessed: religious service attendance, frequency of prayer, religious salience, type of God representation, and moral objections to suicide (MOS)...

Introduction: Over the past decade, we have moved on from a predominantly morphological and clinical classification of myeloproliferative neoplasms (MPN) to a more evolved classification that accounts for the molecular heterogeneity that is unique to this subgroup of hematological malignancies. This usually incorporates mutations in Janus kinase 2 (JAK2), MPL, and calreticulin (CALR) genes. In this manuscript, we report the frequency of these mutations in a cohort of Indian patients at a tertiary cancer center...

Manipulation of magnons opens an attractive direction in the future energy-efficient information processing devices. Such quasi-particles can transfer and process information free from the troublesome Ohmic loss in conventional electronic devices. Here, we propose to realize topologically protected magnon modes using the interface between the patterned ferrimagnetic insulator thin films of different configurations without the Dzyaloshinskii-Moriya interaction. The interface thus behaves like a perfect waveguide to conduct the magnon modes lying in the band gap...
