Background: Recent data have suggested a substantial incidence of atrial arrhythmias (AAs) in cardiac sarcoidosis (CS). Our study aims were to first assess how often AAs are the presenting feature of previously undiagnosed CS. Second, we used prospective follow-up data from implanted devices to investigate AA incidence, burden, predictors, and response to immunosuppression. Methods and Results: This project is a substudy of the CHASM-CS (Cardiac Sarcoidosis Multicenter Prospective Cohort Study; NCT01477359). Inclusion criteria were presentation with clinically manifest cardiac sarcoidosis, treatment-naive status, and implanted with a device that reported accurate AA burden. Data were collected at each device interrogation visit for all patients and all potential episodes of AA were adjudicated. For each intervisit period, the total AA burden was obtained. A total of 33 patients met the inclusion criteria (aged 56.1 +/- 7.7 years, 45.5% women). Only 1 patient had important AAs as a part of the initial CS presentation. During a median follow-up of 49.1 months, 11 of 33 patients (33.3%) had device-detected AAs, and only 2 (6.1%) had a clinically significant AA burden. Both patients had reduced burden after CS was successfully treated and there was no residual fluorodeoxyglucose uptake on positron emission tomography scan. Conclusions: First, we found that AAs are a rare presenting feature of clinically manifest cardiac sarcoidosis. Second, AAs occurred in a minority of patients at follow-up; the burden was very low in most patients. Only 2 patients had clinically significant AA burden, and both had a reduction after CS was treated. REGISTRATION: URL: https://www.clinicaltrials.gov; unique identifier NCT01477359.

Biomimetic actuators have seemingly infinite potential for use in previously unexplored areas. However, large stresses and a rapid water response are difficult to realize in soft actuators, owing to which their practical applicability is currently limited. In this paper, a new method for designing and fabricating humidity-responsive sturdy hard actuator. By combining a rigid matrix and hydrophilic water domains consisting of dynamic interlocking cation-? blocks, high-performance polymer actuator was synthesized that swell rapidly in response to a water gradient in their environment, resulting in unprecedentedly large stresses. More critically, the strong interlocking cation-? blocks reform and the intermolecular distance is reduced when the water is removed, allowing the deformed actuator to revert its original shape. The proposed design principle can potentially be extended to produce different types of sturdy actuators with rapid water responsiveness.

Multidrug resistance (MDR) of cancer cells is a significant challenge in chemotherapy, highlighting the urgent medical need for simple and reproducible strategies to reverse this process. Here, we report the development of an active tumor-targeting and redox-responsive nanoplatform (PA-ss-NP) using hyaluronic acid-g-cystamine dihydrochloride-poly-epsilon-(benzyloxycarbonyl)-L-lysine (HA-ss-PLLZ) to co-deliver paclitaxel (PTX) and apatinib (APA) for effective reversal of MDR. This smart nanoplatform specifically bound to CD44 receptors, leading to selective accumulation at the tumor site and uptake by MCF-7/ADR cells. Under high concentrations of cellular glutathione (GSH), the nanocarrier was degraded rapidly with complete release of its encapsulated drugs. Released APA effectively inhibited the function of the P-glycoprotein (P-gp) drug pump and improved the sensitivity of MDR cells to chemotherapeutic agents, leading to the recovery of PTX chemosensitivity in MDR cells. As expected, this newly developed intelligent drug delivery system could effectively control MDR, both in vitro and in vivo.

Classic dendrimers are not used in many specific applications such as simultaneous loading of different drugs due to the existence of identical end groups. The possibility of designing the structure in dendrimers paves the way to synthesize more complicated dendrimers. This includes the creation of various types of peripheral groups on the surface of dendrimers to synthesize for example Janus dendrimers. Nowadays, three main methods are proposed for the synthesis of Janus dendrimers in which the high amount of conventional dendrimers is produced. The goal of this work is to develop a new method for synthesis of Janus dendrimers without production of conventional dendrimers. The present method has three main stages for the synthesis of Janus dendrimers including synthesis of 5th generation PPI dendrimer with cystamine core and hydrophobic surface, conversion of disulfide bonds to thiol group using a structure scission approach, and the formation of PAMAM hydrophilic dendrons with amine end groups. Different analyses including FT-IR, NMR, DLS, and GPC are used to prove the success of the synthesis route. Also, due to application of dendrimers in drug delivery including solubility improvement of hydrophobic drugs, Janus dendrimers are used to improve solubility of tetracycline and dexamethasone in presence of different generations of Janus dendrimers. Since the Janus dendrimers have both hydrophilic and hydrophobic ends, as well as having numerous terminal groups and numerous internal cavities, they have resulted in significant improvements in drug solubility. Also, solubility of the two hydrophobic drugs in water was increased by increasing concentration and generation of dendrimer.

Inhibition performance of 2,2′-diaminodiethyl disulfide (DA) was studied against mild steel (MS) corrosion in 0.5 M HCl. Electrochemical impedance spectroscopy (EIS), potentiodynamic (PD) polarization measurements were utilized to investigate the influence of inhibitor concentration and temperature on efficiency, as well as explanation of inhibition mechanism. Scanning electron microscopy (SEM) analysis was utilized to investigate the surface damages due to corrosion, in the absence and presence of inhibitor molecules. PD data revealed that the studied molecule exhibits mixed type inhibitor behavior on steel surface. Moreover, the calculated free adsorption energy (Delta G(ads)(o)) value is 38.45 kJ mol(-1), which indicates to strong adsorptive interaction by both physical and chemical means. UV-Visible study results supported the idea that there is strong interaction between the surface with the molecule, via its -S and -N atoms. As a consequence, 91.7% inhibition efficiency was determined in presence of 1.0 mM DA. (C) 2020 Elsevier B.V. All rights reserved.

A dumbbell-shaped copolymer (PDMAEMA)(4)-PCL-SS-PCL-(PDMAEMA)(4) with a lower critical solution temperature (LCST) and redox responses was first synthesized by the combination of ring opening polymerization (ROP), click chemistry and atom transfer radical polymerization (ATRP). Then a dumbbell-shaped copolymer (PDMAPS)(4)-PCL-SS-PCL-(PDMAPS)(4) with an upper critical solution temperature (UCST) and redox responses was obtained through the quaternization reaction between DMAEMA and excess 1,3-propane sultone. Both (PDMAEMA)(4)-PCL-SS-PCL-(PDMAEMA)(4) and (PDMAPS)(4)-PCL-SS-PCL-(PDMAPS)(4) were amphiphilic, and they could self-assemble into spherical micelles under certain conditions. Benefitting from the LCST-type thermoresponse of PDMAEMA and UCST-type thermoresponse of PDMAPS, both dumbbell-shaped copolymers (PDMAEMA)(4)-PCL-SS-PCL-(PDMAEMA)(4) and (PDMAPS)(4)-PCL-SS-PCL-(PDMAPS)(4) presented temperature-responsive properties. The morphology and size of their assemblies would be changed when the temperature is altered. Meanwhile, due to the redox-response of disulfide bonds, both (PDMAEMA)(4)-PCL-SS-PCL-(PDMAEMA)(4) and (PDMAPS)(4)-PCL-SS-PCL-(PDMAPS)(4) showed redox-responsive properties. When dl-dithiothreitol (DTT) was added into the systems, disulfide bonds were broken, causing the change of (PDMAEMA)(4)-PCL-SS-PCL-(PDMAEMA)(4) to PCL-(PDMAEMA)(4), while (PDMAPS)(4)-PCL-SS-PCL-(PDMAPS)(4) changed into PCL-(PDMAPS)(4). The distributions of R-h for both (PDMAEMA)(4)-PCL-SS-PCL-(PDMAEMA)(4) and (PDMAPS)(4)-PCL-SS-PCL-(PDMAPS)(4) assemblies broadened with asymmetric peaks, giving rise to curves with double peaks. After 24 h, DLS curves became symmetric with a single peak, and the R-h was about half that of the original assemblies. In the meantime, dispersed spherical micelles could be observed by TEM.

Cancer cells have reductive and acidic environments as compared to the normal body cells. Development of reductive/acidic responsive polymersomes will play a major role in cancer therapy to trigger the release of the loaded drug. In our work, we synthesized three different reductive/acidic dual-responsive polymers, poly[(mPEG-SS-amino) (N,N-diisopropylethylenediamino)phosphazenes] (PPDPs) in different mole ratios of side groups. These PPDPs were characterized by H-1 NMR, P-31 NMR, FT-IR and GPC. After that, the PPDPs were allowed to self-assemble into drug-loaded polymersomes with high loading content and encapsulation efficiency of hydrophilic/hydrophobic anticancer drugs. The hydrophilic anticancer drug doxorubicin hydrochloride (DOX center dot HCl) and hydrophobic drug doxorubicin were used. These PPDPs-based polymersomes showed reductive/acidic stimuli-responsive release of anticancer drugs. Moreover, these polymersomes also exhibited suitable hydrodynamic diameters, which will facilitate the longtime circulation in bloodstream due to avoiding renal clearance and close contact to the tumor cells in vascular sections due to enhanced permeability and retention effect. Collectively, these developed polymersomes may provide an effective platform for anticancer drugs delivery.

Deep tumor penetration, long blood circulation, rapid drug release, and sufficient stability are the most concerning dilemmas of nano-drug-delivery systems for efficient chemotherapy. Herein, we develop reduction/oxidation-responsive hierarchical nanoparticles co-encapsulating paclitaxel (PTX) and pH-stimulated hyaluronidase (pSH) to surmount the sequential biological barriers for precise cancer therapy. Poly(ethylene glycol) diamine (PEG-dia) is applied to collaboratively cross-link the shell of nanoparticles self-assembled by a hyaluronic acid-stearic acid conjugate linked via a disulfide bond (HA-SS-SA, HSS) to fabricate the hierarchical nanoparticles (PHSS). The PTX and pSH coloaded hierarchical nanoparticles (PTX/pSH-PHSS) enhance the stability in normal physiological conditions and accelerate drug release at tumorous pH, and highly reductive or oxidative environments. Functionalized with PEG and HA, the hierarchical nanoparticles preferentially prolong the circulation time, accumulate at the tumor site, and enter MDA-MB-231 cells via CD44-mediated endocytosis. Within the acidic tumor micro-environment, pSH would be partially reactivated to decompose the dense tumor extracellular matrix for deep tumor penetration. Interestingly, PTX/pSH-PHSS could be degraded apace by the completely activated pSH within endo/lysosomes and the intracellular redox micro-environment to facilitate drug release to produce the highest tumor inhibition (93.71%) in breast cancer models.
