Controlled Release of RNAi Molecules by Tunable Supramolecular Hydrogel Carriers.

Local, sustained release and presentation of RNAi therapeutics can be achieved with hydrogel delivery systems. Here we show the development of a supramolecular hydrogel into a local RNAi delivery system. By careful material design, two simple but effective strategies are introduced to obtain controlled release of two classes of RNAi therapeutics, i.e. microRNA and antimiR. It was shown that the release of microRNA could be regulated using cholesterol-modification for interaction with the supramolecular hydr...

Defining drug and target protein distributions after stent-based drug release: Durable versus deployable coatings.

Drug nanocrystallisation within liposomes.

Liposomes are phospholipid bilayer vesicles that have been explored in pharmaceutical research as drug delivery systems for >50 years. Despite being important to their morphology and drug release pattern, the physical state of the drug within liposomes (liquid, solid, crystalline form) is often overlooked. This review focuses on precipitation of drug within liposomes, which can result in the formation of confined nanocrystals, and consequent changes in liposome morphology and drug release patterns. The ty...

Carriers that can afford tunable physical and structural changes are envisioned to address critical issues in controlled drug delivery applications. Herein, we report photo-responsive conjugated polymer nanoparticles (CPNs) functionalized with donor-acceptor Stenhouse adduct (DASA) and folic acid units for controlled drug delivery, release and imaging. Upon visible light (λ = 550 nm) irradiation, CPNs undergo structure, color, and polarity changes simultaneously that swell and open-up CPNs to release encap...

The molecularly imprinted polymer essentials: curation of anticancer, ophthalmic, and projected gene therapy drug delivery systems.

The development of polymeric materials as drug delivery systems has advanced from systems that rely on classical passive targeting to carriers that can sustain the precisely controlled release of payloads upon physicochemical triggers in desired microenvironment. Molecularly imprinted polymers (MIP), materials designed to capture specific molecules based on their molecular shape and charge distribution, are attractive candidates for fulfilling these purposes. In particular, drug-imprinted polymers coupled w...

Controlled Drug Release with Surface-Capped Mesoporous Silica Nanoparticles and Its Label-Free In Situ Raman Monitoring.

Mesoporous silica nanoparticles (MSNs) have drawn attention as efficient nanocarriers for drug delivery systems owing to their unique physiochemical properties. However, systemically controlling the kinetics of drug release from the nanocarriers and in situ monitoring of the drug release are still challenging. Here, we report surface-capped MSNs used for controlled drug release and demonstrate label-free in situ Raman monitoring of released drugs based on the molecule-specific spectral fingerprints. By capp...

How treatment improvement in ADHD and cocaine dependence are related to one another: A secondary analysis.

Attention-deficit hyperactivity disorder (ADHD) is overrepresented among individuals seeking treatment for substance use disorders. We previously reported that treatment with extended release mixed amphetamine salts (MAS-XR) increased abstinence, compared to placebo, among patients with co-occurring ADHD and cocaine dependence. This secondary analysis investigates the temporal relationship between ADHD improvement and cocaine abstinence in the first six weeks of the trial.

Effect of vascular scaffold composition on release of sirolimus.

Despite extensive development of bioresorbable drug-eluting vascular scaffolds it is still challenging to achieve controlled drug delivery. The lack of capacity for adjusting the drug dose and inadequate release behavior are one of the main reasons of the side effects. However, so far, mainly biodegradable drug-eluting coatings of metallic stents have been studied in regard to explain drug release mechanisms. The objective of this study was to develop degradable polymer coatings applicable to bioresorbable ...

Using ADHD Medications to Treat Coexisting ADHD and Reading Disorders: A Systematic Review.

Attention-deficit/hyperactivity disorder (ADHD), the most common pediatric neurobehavioral disorder, frequently presents with co-existing reading disorders (RD). Despite this, it is unclear whether medication improves symptoms and function in children with comorbid ADHD and RD. We present a systematic review of studies investigating the effects of ADHD medications on ADHD symptoms, academic outcomes, and neuropsychological measures in this important group.

The effect of linkers on the self-assembling and anti-tumor efficacy of disulfide-linked doxorubicin drug-drug conjugate nanoparticles.

Drug-drug conjugate nanoparticles (DDC NPs) is a potential method for overcoming poor solubility and nonspecific action in cancer therapy, which is based on its high drug loading efficiency and passive tumor-target properties. Our laboratory has prepared DOX-SS-DOX NPs based on disulfide-linked doxorubicin (DOX) drug-drug conjugate, which showed well physical stability and similar anti-tumor efficacy as liposomes. However, how structures of DDCs influence the self-assembling and anti-tumor efficacy is still...

Implantable small device enabled with magnetic actuation for on-demand and pulsatile drug delivery.

We prepared an implantable device of small volume (SID) that is enabled with on-demand, pulsatile drug release. The device was designed to be actuated via a magnetic field; hence, there was no need for a battery. The device was actuated when the magnet was applied from the outside and infused the drug solution outward via the outlet ports in the device. When there was no external magnetic field, no drug was released. In this work, we varied the amount of delivered drug by varying the number of outlet ports....
