#1
Chen Huang, Haijun Mei, Min Zhou, Xiaobing Zheng
A novel drug-eluting stent (DES) is required to target vascular smooth muscle cells (SMCs) without harming endothelial cells (ECs). Platelet-derived growth factor (PDGF) is critical for the proliferation and migration of SMCs. Sunitinib [a PDGF receptor (PDGFR) tyrosine kinase inhibitor]‑eluting stents may therefore inhibit neointimal formation. The aim of the present study was to examine the stent‑based delivery of sunitinib in a rabbit carotid model; in addition, the effects of sunitinib were evaluated in vitro...

Indoleamine 2,3-dioxygenase (IDO) is a rate limiting enzyme in tryptophan-degrading pathways and IDO activity results in immune suppression. Targeting IDO is a strategy of cancer immunotherapies. Our previous studies demonstrate that delivery of short hairpin against IDO (IDO shRNA) suppresses tumor growth and increases neutrophils infiltration into tumor. Neutrophils reveal antitumorigenic "N1" or protumorigenic "N2" phenotype in tumor microenvironment. However, the function of IDO shRNA-induced neutrophils is not clear...

INTRODUCTION: Cognitive aids (CAs), including emergency manuals and checklists, have been recommended as a means to address the failure of healthcare providers to adhere to evidence-based standards of treatment during crisis situations. Unfortunately, users of CAs still commit errors, omit critical steps, fail to achieve perfect adherence to guidelines, and frequently choose to not use CA during both simulated and real crisis events. We sought to evaluate whether the mode in which a CA presents information (ie, paper vs...

Oxidative stress (OS) impact on a single neuron's function in vivo remains obscure. Using C. elegans as a model organism, we report the effect of paraquat (PQ)-induced OS on wild type worms on the function of the ASH polymodal neuron. By calcium (Ca(2+)) imaging, we quantified ASH activation upon stimulus delivery. PQ-treated worms displayed higher maximum depolarization (peak of the Ca(2+) transients) compared to untreated animals. PQ had a similar effect on the ASH neuron response time (rising slope of the Ca(2+) transients), except in very young worms...

P Mascheroni, R Penta
We investigate the impact of microvascular geometry on the transport of drugs in solid tumors, focusing on the diffusion and consumption phenomena. We embrace recent advances in the asymptotic homogenization literature starting from a double Darcy, double advection-diffusion-reaction system of partial differential equations that is obtained exploiting the sharp length separation between the intercapillary distance and the average tumor size. The geometric information on the microvascular network is encoded into effective hydraulic conductivities and diffusivities, which are numerically computed by solving periodic cell problems on appropriate microscale representative cells...

OBJECTIVE: Distribution of PET tracer uptake is elaborately modeled via a general equation used for solute transport modeling. This model can be used to incorporate various transport parameters of a solid tumor such as hydraulic conductivity of the microvessel wall, transvascular permeability as well as interstitial space parameters. This is especially significant because tracer delivery and drug delivery to solid tumors are determined by similar underlying tumor transport phenomena, and quantifying the former can enable enhanced prediction of the latter...

Prabagaran Chandrasekaran, Ruckmani Kandasamy
Development of palatable formulations for pediatric and geriatric patients involves various challenges. However, an innovative development with beneficial characteristics of marketed formulations in a single formulation platform was attempted. The goal of this research was to develop solid oral flexible tablets (OFTs) as a platform for pediatrics and geriatrics as oral delivery is the most convenient and widely used mode of drug administration. For this purpose, a flexible tablet formulation using cetirizine hydrochloride as model stability labile class 1 and 3 drug as per the Biopharmaceutical Classification System was developed...

Genomic applications raise multiple challenges including the optimization of genomic counseling (GC) services as part of the results delivery process. More information on patients' motivations, preferences, and informational needs are essential to guide the development of new, more efficient practice delivery models that capitalize on the existing strengths of a limited genetic counseling workforce. Semi-structured telephone interviews were conducted with a subset of counselees from the Coriell Personalized Medicine Collaborative following online receipt of multiple personalized genomic test reports...

REVIEW
Anthony L Rosner
OBJECTIVE: The purpose of this article is to propose a focused assessment of the identity of chiropractic and its profession, triangulating multiple viewpoints converging upon various aspects and definitions of neurology, manual medicine, and alternative or mainstream medicine. DISCUSSION: Over 120 years since its inception, chiropractic has struggled to achieve an identity for which its foundations could provide optimal health care. Despite recognition of the benefits of spinal manipulation in various government guidelines, advances in US military and Veterans Administration, and persistently high levels of patient satisfaction, the chiropractic profession remains underrepresented in most discussions of health care delivery...

The importance of oral health for overall well-being cannot be overstated. Yet the US dental delivery system struggles to address effectively the two most common oral diseases (caries and periodontal disease), which are among the most prevalent of all chronic diseases and are largely preventable. This article describes the evolution of contemporary US dental care policy and practice, highlighting the challenges resulting from the dental system's separation from the rest of health care, and explores the implications of this divide for the future of oral health policy and system reform...

Log-logistic parametric survival regression model has been used to find out the potential determinants of infant mortality in Bangladesh using the data extracted from Bangladesh Demographic and Health Survey, 2011. First, nonparametric product-limit approach has been used to examine the unadjusted association between infant mortality and covariate of interest. It is found that maternal education, membership of nongovernmental organizations, age of mother at birth, sex of child, size of child at birth, and place of delivery play an important role in reducing the infant mortality, adjusting relevant covariates...

Echinocandins are first-line therapy for candidemia and invasive candidiasis. They are generally safe with few drug interactions, but the stability and pharmacokinetic properties of currently approved echinocandins are such that each was developed for daily intravenous infusion. We sought to discover a novel echinocandin with properties that would enable more flexible dosing regimens, alternate routes of delivery, and expanded utility. Derivatives of known echinocandin scaffolds were generated, and an iterative process of design and screening led to the discovery of CD101, a novel echinocandin that has since demonstrated improved chemical stability and pharmacokinetics...

Glucocorticoids (GC) are widely used to treat acute relapses in multiple sclerosis (MS) patients, but their application is accompanied by side effects due to their broad spectrum of action. Here, we report on the therapeutic option to apply GC via inorganic-organic hybrid nanoparticles (IOH-NP) with the composition [ZrO](2+)[(BMP)0.9(FMN)0.1](2-) (designated BMP-NP with BMP: betamethasone phosphate; FMN: flavinmononucleotide). We found that these BMP-NP have an increased cell type-specificity compared to free GC while retaining full therapeutic efficacy in a mouse model of MS...

BACKGROUND: Issues such as privacy, security, quality, etc. have received considerable attention in discussions of eHealth, mHealth and pHealth. However, comparatively little attention has been paid to the fact that these methods of delivering health care situate Health Information Professionals (HIPs) in an ethical context that is importantly different from that of traditional health care because they assign a fiduciary role to HIPs that they did not have before, their previous technical involvement notwithstanding...
