INTRODUCTION: Anti-vaping public service announcements (PSAs) are intended to discourage vaping or use of electronic nicotine delivery systems (ENDS). However, vaping portrayals in PSAs may have unintended effects if they increase smoking or vaping urges. This study examined benefits and unintended effects of anti-vaping PSAs with vapor portrayals on smoking and vaping-related outcomes. METHODS: Young adult smokers (N = 171) and dual users (N = 122) aged 21-30 years were randomly assigned to view: 1) anti-vaping PSAs with vapor; 2) anti-vaping PSAs without vapor; 3) physical activity PSAs; or 4) anti-smoking PSAs with smoking cues...

As2 O3 -loaded nanoparticles (NPs) based on poly (lactic-co-glycolic acid) (PLGA) were prepared by double emulsion-solvent evaporation method. Then Lactose acid (LA) and/or PEG were modified onto the NPs by chemical covalent coupling through -NH2 and -COOH. The FTIR results showed that LA and PEG could be successfully modified onto the surface of the NPs. All the As2 O3 -loaded PLGA NPs (As2 O3 @PLGA NPs) presented suitable physical stability, favorable size, and spherical shape. The in vitro release rate of As2 O3 from the NPs depended on the surface of the NPs...

The combination of chemotherapy and photothermaltherapy (PTT) via stimuli-responsive nanovesicles has great potential in tumor treatment. In the present study, bubble-generating polymersomes, which can generate bubbles in response to low pH or hyperthermia, were fabricated to simultaneously encapsulate chemotherapeutic drug and photosensitizing agent for the synergistic chemo-photothermal tumor therapy. Photosensitizer indocyanine green (ICG) was encapsulated into the bilayer of polymersomes formed by amphiphilic triblock copolymer PCL8000 -PEG8000 -PCL8000 through thin film re-hydration method, while chemotherapeutic doxorubicin (DOX) was loaded into the hydrophilic lumen using a transmembrane ammonium bicarbonate gradient loading procedure...

Novel excipients are indispensable in development of modern, advanced drug delivery systems and biotechnology-derived drugs. Although numerous novel excipients are developed for pharmaceutical use, they are not frequently seen in medicinal products due to the strict regulatory requirements and perception that their use makes new product evaluation more complex with risk of delays in the approval process. Regulators regard novel excipients as new substances and whenever new excipient is used in a formulation it must be subjected to full evaluation, similarly to the one required for new active substance...

Osteoarthritis (OA) is the most common degenerative disease of the joint. Despite many reports and numerous clinical trials, OA is not entirely understood, and there is no effective treatment available for this disease. To satisfy this unmet medical need, drug delivery systems (DDSs) containing disease-modifying OA drugs (DMOADs) for intra-articular (IA) administration are required to improve the health of OA patients. DDSs should provide controlled and/or sustained drug release, enabling long-term treatment with a reduced number of injections...

Many cancers such as human breast cancer and lung cancer easily metastasize to bones, leading to the formation of secondary tumors in advanced stage. Based on the CD44-targeted effect of oHA and bone-targeted effect of ALN, we prepared a reduction-responsive, CD44 receptor-targeting and bone-targeting nano-micelle, called CUR-loaded ALN-oHA-S-S-CUR micelles. In this study, we aimed to evaluate the antitumor activity and bone-targeting ability of CUR-loaded ALN-oHA-S-S-CUR micelles. The in vivo experiment results showed that a larger number of micelles was gathered in the bone metastatic tumor tissue and reduced the bone destruction...

Installation of an antibody-recruiting moiety on the surface of disease-relevant cells can lead to the selective destruction of targets by the immune system. Such an approach can be an alternative strategy to traditional chemotherapeutics in cancer therapy and possibly other diseases. Herein we describe the development of a new strategy to selectively label targets with an antibody-recruiting moiety through its covalent and stable installation, complementing existing methods of employing reversible binding...

Few industries match the scale of health care. In the United States alone, an estimated 85% of the population has at least 1 health care encounter annually and at least one quarter of these people experience 4 to 9 encounters annually. A single visit requires collaboration among a multidisciplinary group of clinicians, administrative staff, patients, and their loved ones. Multiple visits often occur across different clinicians working in different organizations. Ineffective care coordination and the underlying suboptimal teamwork processes are a public health issue...

AIM: Inflammation is a process that underlies sight-threatening ocular surface diseases, and gene supplementation with the plasmid that encodes for p-IL10 will allow the sustained de novo synthesis of the cytokine to occur in corneal cells, and provide a long-term anti-inflammatory effect. This work describes the development of solid lipid nanoparticle systems for the delivery of p-IL10 to transfect the cornea. RESULTS: In vitro, vectors showed suitable features as nonviral vectors (size, ζ-potential, DNA binding, protection and release), and they were able to enter and transfect human corneal epithelial cells...

Gabapentin (GBP), an antiepileptic and anti-neuropathic agent, suffers from short half-life (5-7 h), has narrow absorption window, and is absorbed via carrier-mediated mechanism resulting in frequent dosing, poor compliance, and poor bioavailability (<60%). Moreover, GBP is a freely water-soluble drug, thus it is considered a challenging candidate to be formulated as extended release dosage form. In this study, raft forming systems were investigated as a potential drug delivery system for prolonging gastric residence time of GBP...

BACKGROUND: Chronic respiratory diseases, whose one of the hallmarks is oxidative stress, are still incurable and need novel therapeutic tools and pharmaceutical agents. The phenolic compounds contained in grape are endowed with well-recognized anti-oxidant, anti-inflammatory, anti-cancer, and anti-aging activities. Considering that natural anti-oxidants, such as proanthocyanidins, have poor water solubility and oral bioavailability, we have developed a drug delivery system based on solid lipid nanoparticles (SLN), apt to encapsulate grape seed extract (GSE), containing proanthocyanidins...

Diabetes mellitus, a metabolic disorder of glucose metabolism, is mainly associated with insulin resistance to the body cells, or impaired production of insulin by the pancreatic β-cells. Insulin is mainly required to regulate glucose metabolism in type 1 diabetes mellitus patients; however, many patients with type 2 diabetes mellitus also require insulin, especially when their condition cannot be controlled solely by oral hypoglycemic agents. Hence, major researches are ongoing attempting to improve the delivery of insulin in order to make it more convenient to patients who experience side effects from the conventional treatment procedure or non-adherence to insulin regimen due to multiple comorbid conditions...

Introduction Sufficient infrastructure for information and communications technology (ICT) and a well-established policy are necessary factors for smooth implementation of telemedicine. However, despite these necessary conditions being met, there are situations where telemedicine still fails to be accepted as a system due to the low receptivity of stakeholders. In this study, we analyse stakeholders' resistance to an organization's implementation of telemedicine. Focusing on the physicians' interests, we propose a strategy to minimize conflicts and improve acceptance...

A green method was used for the fabrication of coaxial nanofibers for use in biomedical applications. Coaxial nanofiber mats were fabricated by emulsion electrospinning from poly(vinyl alcohol) (PVA) and Dextran sulfate (Dex) blends loaded with ciprofloxacin (Cipro) as a model drug dissolved in edible oil. The ratio of the PVA/Dex mixture was optimized and nanofibers were stabilized against disintegration in water by thermal treatment at 120 °C. The morphology of the prepared nanofibers was observed by scanning electron microscopy and the structure of the core-shell nanofibers was confirmed by transmission electron microscopy...

Chemically crosslinked covalent hydrogels form a permanent and often strong network, and have been extensively used so far in drug delivery and tissue engineering. However, it is more difficult to induce dynamic and highly tunable changes in these hydrogels. Noncovalently formed hydrogels show promise as inherently reversible systems with an ability to change in response to dynamic environments, and have garnered strong interest recently. In this Personal Account, we elucidate a few key attractive properties of noncovalent hydrogels and describe recent developments in hydrogels crosslinked using various different noncovalent interactions...
