The host actin cytoskeleton is utilized by an assortment of pathogenic bacteria to colonize and cause disease in their hosts. Two prominently studied actin-hijacking bacteria are enteropathogenic Escherichia coli (EPEC) and Listeria monocytogenes. EPEC form actin-rich pedestals atop its host cells to move across the intestinal epithelia, while Listeria monocytogenes generate branched actin networks arranged as actin clouds around the bacteria and as comet tails for propulsion within and amongst their host cells...

Bioaerosols consist of aerosols originated biologically such as metabolites, toxins, or fragments of microorganisms that are present ubiquitously in the environment. International interests in bioaerosols have increased rapidly to broaden the pool of knowledge on their identification, quantification, distribution, and health impacts (e.g., infectious and respiratory diseases, allergies, and cancer). However, risk assessment of bioaerosols based on conventional culture methods has been hampered further by several factors such as: (1) the complexity of microorganisms or derivatives to be investigated; (2) the purpose, techniques, and locations of sampling; and (3) the lack of valid quantitative criteria (e...

Oligodeoxynucleotide (ODN)-loaded gelatine nanoparticles (GNPs) have proven their outstanding potential in the treatment of allergic diseases such as equine asthma and canine atopic dermatitis, which are appropriate models for the corresponding human diseases. To encourage the development of a marketable product, long term stability and sterility needs to be ensured. In this work, we aimed to advance freeze-drying options to stabilise ODN-loaded GNPs. Matrix-assisted laser desorption/ionisation mass spectrometry time-of-flight was implemented as a versatile tool to assess ODN stability...

BACKGROUND: Aspirin desensitization has been associated with benefit in management of aspirin exacerbated respiratory disease (AERD). An intervention that would encourage aspirin desensitization to be performed more frequently has substantial potential for improving outcomes and quality of life in patients with AERD. OBJECTIVE: We investigated whether omalizumab administration would be associated with attenuation of aspirin-provoked bronchospasm in patients with AERD undergoing aspirin desensitization...

The prevalence of IgE-mediated disease increased significantly during the 20th century. In developed countries, about 20% of people have atopic disease, which consumes significant amounts of healthcare funding. For example, in UK general practice, allergic conditions account for 6% of consultations and ~10% of prescribing costs [1]. Whilst most studies of allergy focus on children and adolescents, relatively little has been written about allergy in older people, although food allergy may be increasingly common in this group [2]...

This report summarized current knowledge and findings relevant to environmental and genetic risk factors in brain tumors, with a particular focus on glioma. To date, the established risk factors for brain tumors are family history and ionizing radiation exposure; whereas there is an inverse association between tumors and other factors such as history of allergies, atopic conditions, chickenpox, and varicella zoster virus infection. To identify inherited genetic variants impacting susceptibility of brain tumors, large scale familial linkage-scan pedigree analysis, population-based candidate genes, and genome-wide association study were performed...

Acoustic cavitation (the growth, oscillation, and rapid collapse of bubbles in a liquid) occurs in all liquids irradiated with sufficient intensity of sound or ultrasound. The collapse of such bubbles creates local heating and provides a unique source of energy for driving chemical reactions. In addition to sonochemical bond scission and formation, cavitation also induces light emission in many liquids. This phenomenon of sonoluminescence (SL) has captured the imagination of many researchers since it was first observed 85 years ago...

The Zn2+ stored in the secretory vesicles of glutamatergic neurons is coreleased with glutamate upon stimulation, resulting in the elevation of extracellular Zn2+ concentration (CZn2+ex). This elevation of CZn2+ex regulates the neurotransmission and facilitates the fibrilization of amyloid-β (Aβ). However, the exact CZn2+ex surrounding neurons under (patho)physiological conditions is not clear and the connection between CZn2+ex and the Aβ fibrilization remains obscure. Here, a silicon nanowire field-effect transistor (SiNW-FET) with the Zn2+ -sensitive fluorophore, FluoZin-3 (FZ-3), to quantify the CZn2+ex in real time is modified...

INTRODUCTION: Human T-cell lymphotropic virus type 1 (HTLV-1)induces exaggerated Th1 responses, whereas atopy is associated with exacerbated Th2 responses. METHODS: Here, a cross-sectional study compared the prevalence of atopy in HTLV-1 carriers and HAM/TSP patients. It also compared the spontaneous cytokine production in HTLV-1-infected individuals. A retrospective cohort study evaluated the development of neurological manifestations in atopic and non-atopic carriers...

BACKGROUND: Currently there is no cure for severe atopic dermatitis (AD). Wet-wrap therapy (WWT) has also been used to treat pediatric AD and shown a satisfactory effectiveness, but clinical evidence supporting the use of WWT on severe adult AD is still insufficient. METHODS: Twelve patients (8 men and 4 women) with severe AD (SCORing Atopic Dermatitis [SCORAD] score≥50) treated between January 2015 and September 2017 in our hospital were included. The patients underwent WWT (daily dose: 15g halometasone cream+100g Vaseline ointment) twice daily for 2 hours/session for 7 days...

Diet and nutrition play an important role in the development and management of food allergy. The diet of expectant mothers can have an effect on their offspring in terms of allergic outcomes. A host of confounding factors may influence this, with a maternal diet rich in fruits and vegetables, fish, vitamin D-rich foods associated with a lower risk of allergic disease in their children. More surprisingly, the consumption of milk and butter has also been shown to have a protective effect, especially in a farm environment...

We present the case of a 3-month-old infant with atopic dermatitis who developed severe impetigo. The child was born to Syrian refugees shortly after they arrived in Canada. The case demonstrates the rapid and nearly complete resolution of dramatic skin findings after a course of hydrocortisone ointment and oral antibiotics with adjuvant measures. For resettled refugees, access to family physicians and local language proficiency are common barriers that negatively impact their health and healthcare. We discuss some aspects of how the healthcare model in one Canadian city addresses these issues in the context of this case...

Vitamin D (vitD) is involved in immune regulation, and its receptor has been identified in several tissues including lung, adipose tissue, brain, and skin. Based on these observations, it has been suggested that vitD has an essential role not only in bone metabolism but also in other diseases such as atopic dermatitis (AD), bronchial asthma (BA), attention-deficit/hyperactivity disorder (ADHD), and obesity because the affected tissues express vitD receptors. Furthermore, obesity, AD, and BA are regarded as inflammatory diseases...

Atopic dermatitis (AD) is a chronic inflammatory skin disease resulting pruritic, erythema, edema, excoriation, and thickening of the skin, and thus leads to significant impairment in the patient's life. The objective of this study is to develop a steroid drug [prednisolone (PS)]-loaded coatable hydrogel for the treatment of AD. PS-loaded hydrogel was composed of PVA entrapped in mildly crosslinked alginate (PS-loaded PVA/ALG hydrogel). The PS concentration to be loaded in the hydrogel that takes AD efficacy without cell necrosis was determined from the cytotoxicity test using human dermal fibroblasts...

Thymic stromal lymphopoietin(TSLP) is recognized as key cytokine in T helper type 2 (Th 2) cell differentiation and contributes to the pathogenesis of atopic disease. The TSLP gene on chromosome 5q22.1 and atopic cytokine gene on 5q31 are adjacent to each other. Based on their genetic location, it is suggested that the TSLP gene is involved in the progression or activity of atopic disease. Genetic association studies involving TSLP single nucleotide polymorphisms (SNPs) and allergic rhinitis or asthma in different racial group have yielded disparate and inconsistent results...
