Mast cells are important immune cells that have significant roles in mediating allergy and asthma. Therefore, studying the molecular mechanisms regulating these and other processes in mast cells is important to elucidate. Methods such as lipofection, transduction, and electroporation are often employed to dissect these mechanisms by disrupting gene expression in mast cell lines. However, as with other leukocytes, human mast cells (HMCs) are often refractory to the delivery of plasmids by lipofection. In this study, we investigated the utility of lipid nanoparticles (LNPs) containing the ionizable cationic lipids 1,2-dioleoyloxy-3-dimethylaminopropane, 1,2-dioleyloxy-3-dimethylaminopropane, or 2,2-dilinoleyl-4-(2-dimethylaminoethyl)-[1,3]-dioxolane for the delivery of plasmid DNA into HMC lines...

OBJECTIVES/HYPOTHESIS: Reconstruction of craniofacial cartilagenous defects are among the most challenging surgical procedures in facial plastic surgery. Bioengineered craniofacial cartilage holds immense potential to surpass current reconstructive options, but limitations to clinical translation exist. We endeavored to determine the viability of utilizing adipose-derived stem cell-chondrocyte co-culture and three-dimensional (3D) printing to produce 3D bioscaffolds for cartilage tissue engineering...

Grape seeds full with oil and also rich in hypoglycemic ingredients. This study is to improve the comprehensive utilization of grape seeds and the quality of grape seeds oil. Extract water soluble active substances before extracting oil from grape seeds, which show the grape seeds in water soluble extracts containing TP, TC, PC contents, respectively, are 171.1 ± 1.1, 658.8 ± 0.2, 482.3 ± 0.2 (mg GSAE/g). Also we found GSAE samples containing catechin and epicatechin were 44.12 ± 0.21 mg/mL, 111.23 ± 1...

BACKGROUND: Over the past century, life expectancy at birth in Canada has risen substantially. However, these gains in the quantity of life say little about gains in the quality of life. DATA AND METHODS: Health-adjusted life expectancy (HALE), an indicator of quality of life, was estimated for the household and institutional populations combined every four years from 1994/1995 to 2015. Health status was measured by the Health Utilities Index Mark 3 instrument in two national population health surveys, and was used to adjust life expectancy...

An evidence-practice gap for use of celiac disease testing can lead to poor resource utilization. False positive tests may lead to unnecessary diet changes, gastroenterology consults, parental/patient concern, and additional testing and expenses complicated by varied available celiac bundles. An understanding of pediatric provider practices according to guideline recommendations further improves this gap.

Emma Hamilton, Delida Sanchez
The current study explored narrative roles among individuals convicted of a sexual offense. Narrative roles in a criminal context are defined as specific personal accounts utilized by offenders to justify illegal behavior. The chosen theoretical framework recognized four primary offender roles: Revengeful Mission/Romantic Quest, Professional, Victim, and Tragic Hero. A total of 23 interviews were conducted with individuals convicted of a sexual offense ( n = 11 contact, n = 12 noncontact) to explore and compare narrative roles between contact and noncontact offenders...

OBJECTIVES: Taxing psychosocial stress and defensive coping have been associated with hypoactivity in cortisol, a vasoconstrictive agent. Estradiol has vasodilatory properties with cardio- and neuroprotective effects. It can however also induce α1 -adrenergic vasoconstrictive responsiveness. We aimed to determine whether the cortisol-to-estradiol ratio (Cort:E2) may augment α1 -adrenergic responsiveness and hypertension risk when habitually using defensive coping. METHODS: African (n = 168) and Caucasian (n = 207) men and women (46 ± 9 years) were included...

Nanoparticles comprising three or more different metals are challenging to prepare. General methods that tackle this challenge are highly sought after as multicomponent metal nanoparticles display favorable properties in applications such as catalysis, biomedicine, and imaging. Herein, we report a practical and versatile approach for the synthesis of nanoparticles composed of up to four different metals. This method relies on the thermal decomposition of nanostructured composite materials assembled from platinum nanoparticles, a metal-organic framework (ZIF-8), and a tannic acid coordination polymer...

The electron blocking layer (EBL) is important to balance the charge carrier transfer and achieve highly efficient quantum dot light-emitting diodes (QLEDs). Here we report the utilization of a soluble tert-butyldimethylsilyl chloride-modified poly(p-phenylene benzobisoxazole) (TBS-PBO) as an EBL for simultaneous good charge carrier transfer balance while maintaining high current density. We show that the versatile TBS-PBO blocks excess electron injection into the QDs, thus leading to better charge carrier transfer balance...

Optic neuritis remains a common diagnosis with controversial management. Although typical optic neuritis is often associated with "good" recovery of visual acuity, patients are often left with persistent impairments of contrast sensitivity, color vision, and visual field. These permanent visual deficits correlate with structural injury to the anterior visual pathway and are closely linked to visual quality of life. High dose corticosteroids are commonly used for patients with acute optic neuritis...

BACKGROUND: The optimal dose and schedule of mycophenolate mofetil (MMF) in pediatric allogeneic stem cell transplant recipients remains to be determined. We previously reported safety and pharmacokinetics of MMF at 900 mg/m2 q6h dosing. This study was conducted to investigate the efficacy of tacrolimus plus q8h MMF dosing for acute graft versus host disease (GVHD) prophylaxis in a heterogeneous population of children, adolescent, young adult allogeneic stem cell transplant recipients, utilizing multiple allogeneic donor sources...

Utilization of [Mo2S2O2(H2O)6]2+ and a tellurite anion led to the formation of three new clusters, 1-3, with unique structural features. The tellurite anion not only templated the formation of [(Mo2O2S2)4(TeO3)(OH)9]3- 1 and [(Mo2O2S2)12(TeO3)4(TeO4)2 (OH)18]10- 3, but also the in situ generation of two different types of dimeric {Te2O6} based moieties induced the spontaneous assembly of the chiral [(Mo2O2S2)10(TeO3)(Te2O6)2(OH)18]8- anionic cluster, 2.

BACKGROUND: Cancer is one of the leading causes of death worldwide. Over the years, a number of conventional cytotoxic approaches for neoplastic diseases has been developed. However, due to their limited effectiveness in accordance with the heterogeneity of cancer cells, there is a constant search for therapeutic approaches with improved outcome, such as immunotherapy that utilizes and enhances the normal capacity of the patient's immune system. METHODS: Chimeric Antigen Receptor (CAR) T-cell therapy involves genetic modification of patient's autologous T-cells to express a CAR specific for a tumor antigen, following by ex vivo cell expansion and re-infusion back to the patient...

The Readiness for Interprofessional Learning Scale (RIPLS) was developed to assess undergraduate readiness for engaging in interprofessional education (IPE). It has become an accepted and commonly used instrument. To determine utility of a modified 16-item RIPLS instrument, exploratory and confirmatory factor analyses were performed. Data used were collected from a pre- and post-intervention study involving 360 New Zealand undergraduate students from one university. Just over half of the participants were enrolled in medicine (51%) while the remainder were in pharmacy (27%) and nursing (22%)...
