Turja Nandy, Ronald A Coutu, Cristinel Ababei
Carbon monoxide (CO) is a toxic gas, and environmental pollutant. Its detection and control in residential and industrial environments are necessary in order to avoid potentially severe health problems in humans. In this review paper, we discuss the importance of furthering research in CO sensing technologies for finding the proper material with low-range detection ability in very optimum condition. We build our discussion through the perspective of a cyber-physical system (CPS) modeling framework, because it provides a comprehensive framework to model and develop automated solutions for detection and control of poisonous chemical compounds, such as the CO...

Traumatic brain injury (TBI) is associated with long-term disabilities and devastating chronic neurological complications including problems with cognition, motor function, sensory processing, as well as behavioral deficits and mental health problems such as anxiety, depression, personality change and social unsuitability. Clinical data suggest that disruption of the thalamo-cortical system including anatomical and metabolic changes in the thalamus following TBI might be responsible for some chronic neurological deficits following brain trauma...

INTRODUCTION: The overall goal of the Alzheimer's Disease Neuroimaging Initiative (ADNI) is to validate biomarkers for Alzheimer's disease (AD) clinical trials. ADNI is a multisite, longitudinal, observational study that has collected many biomarkers since 2004. Recent publications highlight the multifactorial nature of late-onset AD. We discuss selected topics that provide insights into AD progression and outline how this knowledge may improve clinical trials. METHODS: We used standard methods to identify nearly 600 publications using ADNI data from 2016 and 2017 (listed in Supplementary material and searchable at http://adni...

INTRODUCTION: Intrahepatic cholestasis of pregnancy is characterised by pruritus and elevated serum bile acids. The pruritus can be severe, and pharmacological options achieve inconsistent symptomatic improvement. Raised bile acids are linearly associated with adverse fetal outcomes, with existing management of limited benefit. We hypothesised that therapeutic plasma exchange removes pruritogens and lowers total bile acid concentrations, and improves symptoms and biochemical abnormalities in severe cases that have not responded to other treatments...

Poor outcomes associated with increased perioperative opioid use have led investigators to seek alternative pain management modalities after total joint arthroplasty. Nonpharmacological approaches, such as electroceuticals, have shown promise. The purpose of this study was to evaluate the effects of "havening," a specific form of psychosensory therapy, on postoperative pain scores and narcotic consumption. In this prospective, randomized controlled trial, the authors compared 19 patients who underwent psychosensory therapy with 22 patients who served as the control group...

Background: Autism spectrum disorder (ASD) has been linked with eating- and feeding-related atypicalities, including food neophobia (FN) (refusal to try unfamiliar foods), since its earliest description. Nevertheless, whether associations between ASD traits and FN extend subclinically into the broader population of children and their potential additive health impacts remains unexplored. Objective: We examined ASD-control group differences in FN and ASD trait-FN trait associations, as well as the ability of FN and autistic traits to predict one index of later health-related outcomes [body mass index (BMI)]...

Copepods of the genus Tigriopus, which are common zooplankton in rocky tide pools, show precopulatory mate-guarding behavior where a male clasps a potential mate to form a pair. While this phenomenon has attracted interest of researchers, methods for its analysis have not been well described. Here we describe procedures for: 1) individual culturing and staging of Tigriopus juveniles and adults, and 2) video-based analysis of their mate-guarding behavior. The culturing method enables experimental control of paring experience of animals as well as the ability to track their development before behavioral tests...

Background:  Tuberculous meningitis (TBM) is the most severe form of tuberculosis. Co-infection with HIV increases the risk of developing TBM, complicates treatment, and substantially worsens outcome. Whether corticosteroids confer a survival benefit in HIV-infected patients with TBM remains uncertain. Hepatitis is the most common drug-induced serious adverse event associated with anti-tuberculosis treatment, occurring in 20% of HIV-infected patients. The suggested concentration thresholds for stopping anti-tuberculosis drugs are not evidence-based...

Diabetic retinopathy (DR) is a leading cause of blindness worldwide. However, 90% of DR caused blindness can be prevented if diagnosed and intervened early. Retinal exudates can be observed at the early stage of DR and can be used as signs for early DR diagnosis. Deep convolutional neural networks (DCNNs) have been applied for exudate detection with promising results. However, there exist two main challenges when applying the DCNN based methods for exudate detection. One is the very limited number of labeled data available from medical experts, and another is the severely imbalanced distribution of data of different classes...

The oxidation of the C-H and C=C bonds of hydrocarbons with H2 O2 catalyzed by non-heme iron complexes with pentadentate ligands is widely accepted as involving a reactive FeIV =O species such as [(N4Py)FeIV =O]2+ formed by homolytic cleavage of the O-O bond of an FeIII -OOH intermediate (where N4Py is 1,1-bis(pyridin-2-yl)- N , N -bis(pyridin-2-ylmethyl)methanamine). We show here that at low H2 O2 concentrations the FeIV =O species formed is detectable in methanol. Furthermore, we show that the decomposition of H2 O2 to water and O2 is an important competing pathway that limits efficiency in the terminal oxidant and indeed dominates reactivity except where only sub-/near-stoichiometric amounts of H2 O2 are present...

Gastric emptying rate in humans is subject to large individual variability, but previous research on the influence of genetics is scarce. Variation in the glucagon-like peptide-1 receptor (GLP1R) gene is a plausible candidate gene to partially explain the high variance. This study aimed to investigate the influence of genetic variation in the GLP1R gene on gastric emptying rate of a glucose solution in humans. Forty eight healthy Caucasian males took part in this investigation. Gastric emptying rate of a 6% glucose solution was assessed using the 13C breath test method and a venous blood sample was obtained from each participant...

The global olive oil industry annually generates approximately 750,000-1,500,000 tons of Olea europaea leaves as waste that are typically burned for energy production. Yet, this agricultural by-product is a rich source of oleanolic acid, a high value triterpenic acid with outstanding pharmaceutical and nutraceutical activities. The present study focuses on the extraction of oleanolic acid from dried O. europaea leaves using aqueous solutions of surface-active ionic liquids as alternative solvents. A number of imidazolium-based ionic liquids with variable chain length, different anions and optional side-chain functionalization was synthesized and employed in the extraction of oleanolic acid...

The increase of the human population is accompanied by growing numbers of livestock to feed this population, as well as by an increase of human invasion into natural habitats of wild animals. As a result, both animals and humans are becoming progressively vulnerable to infections with known (zoonotic) pathogens, but are also increasingly exposed to novel viruses. Global trade as well as climate changes can contribute to pathogen transmission, e.g. through import of infected vectors or expansion of habitats for arthropod vectors such as mosquitoes and midges...

BACKGROUND: Elbow arthroscopy is a difficult surgical technique. Objective metrics can be used to improve safe and effective training in elbow arthroscopy. Force exerted on the elbow tissue during arthroscopy can be a measure of safe tissue manipulation. The purpose of this study was to determine the force magnitude and force direction used by experts during arthroscopic elbow navigation in cadaveric specimens and assess their applicability in elbow arthroscopy training. METHODS: Two cadaveric elbows were mounted on a Force Measurement Table (FMT) that allowed 3-dimensional measurements (x-, y-, and z-plane) of the forces exerted on the elbow...
