AIMS: The clinical performance of the SYNERGY drug-eluting stent (DES) in patients with acute myocardial infarction (MI) has not been investigated in detail. We sought to report on the outcomes after SYNERGY DES (Boston Scientific, Marlborough, MA, USA) implantation in patients with MI undergoing percutaneous revascularisation (PCI). METHODS AND RESULTS: We included all consecutive patients with MI undergoing PCI with the SYNERGY DES and newer-generation DES (n-DES group) in Sweden...

AIMS: The aim of the study was to evaluate the two-year clinical outcome of all-comer trial participants who were treated with two very different thin-strut biodegradable polymer versus thin-strut durable polymer drug-eluting stents (DES). Prolonged clinical outcome after discontinuation of dual antiplatelet therapy is of particular interest, given the highly dissimilar polymer types, amount, distribution, and degradation speed of both biodegradable polymer DES. METHODS AND RESULTS: The BIO-RESORT trial (NCT01674803) randomly assigned 3,514 patients to treatment with biodegradable polymer SYNERGY everolimus-eluting stents (EES) or Orsiro sirolimus-eluting stents (SES), or durable polymer Resolute Integrity zotarolimus-eluting stents (ZES)...

Aims: Delayed healing and endothelial dysfunction may occur with drug-eluting stents (DES), promoting accelerated infiltration of lipids in the neointima and development of neoatherosclerosis (NA). Pathology data suggest durable polymer (DP) of DES to play a major role in this process. Whether biodegradable polymer (BP) may address these issues is uncertain. We compared in vivo vessel healing and NA of current generation BP- or DP-DES using serial optical coherence tomography (OCT) assessments...

BACKGROUND: Alcohol misuse is associated with increased human immunodeficiency virus sexual risk behaviors by women. Drug use, intimate partner violence (IPV), and depressive symptoms frequently co-occur, are well-recognized alcohol misuse comorbidities, and may interact to increase risk behaviors. Using a syndemic framework we examined associations between drug use, IPV, and depressive symptoms and sexual risk behaviors by 400 women with alcohol misuse attending an urban sexually transmitted infections clinic...

BACKGROUND: This paper combines evidence from an ethnographic study of illicit drug use amongst tourists in Ibiza with Bryman's (2004) theoretical model of Disneyization. The principal aim was to construct a new conceptual framework that may help scholars, practitioners and policy makers make sense of dynamic patterns of illegal drug use across bounded play spaces such as tourist resorts, music festivals and nightclubs. METHODS: Ethnographic fieldwork employing a grounded theory design was undertaken over three summers in tourist locations on the Balearic island of Ibiza, including nightclubs, bars, cafes, beaches, airports and hotels...

Benefiting from the integrated functions of cilia and glomeruli in the olfactory system, animals can discriminate various odors even in hostile environments. Inspired by this synergetic system of response and signal processing units, a sensor chip of graphene oxide (GO) and photonic crystals (PCs) is fabricated. The GO aerogel functions like the olfactory cilia, which effectively captures the analytes and generates abundant sensing signals for recognition; and the PCs act as the olfactory glomeruli, whose periodic structure enables selective enhancement of the fluorescent signals to realize further signal processing...

Lymphatic filariasis (LF) is a mosquito-borne disease, broadly endemic in Zambia, and is targeted for elimination by mass drug administration (MDA) of albendazole and diethylcarbamazine citrate (DEC) to at-risk populations. Anopheline mosquitoes are primary vectors of LF in Africa, and it is possible that the significant scale-up of malaria vector control over the past decade may have also impacted LF transmission, and contributed to a decrease in prevalence in Zambia. We therefore aimed to examine the putative association between decreasing LF prevalence and increasing coverage of insecticide-treated mosquito nets (ITNs) for malaria vector control, by comparing LF mapping data collected between 2003-2005 and 2009-2011 to LF sentinel site prevalence data collected between 2012 and 2014, before any anti-LF MDA was started...

Near-infrared (NIR)-absorbing conjugated polymer nanoparticles are interesting for imaging-guided combination therapy, especially for synergistic photothermal therapy and chemotherapy; however, most of them target tumours passively through the enhanced permeability and retention (EPR) effect, leading to low utilization efficiency. To address this problem, we report an active tumour-targeting strategy of tumour-homing chimeric polypeptide-conjugated NIR-absorbing conjugated-polymer nanoparticles as a new class of drug nanocarriers for imaging-guided combination therapy of cancer...

The explosive growth of high-throughput experimental methods and resulting data yields both opportunity and challenge for selecting the correct drug to treat both a specific patient and their individual disease. Ideally, it would be useful and efficient if computational approaches could be applied to help achieve optimal drug-patient-disease matching but current efforts have met with limited success. Current approaches have primarily utilized the measureable effect of a specific drug on target tissue or cell lines to identify the potential biological effect of such treatment...

BACKGROUND: Nanoparticles have become one of the most promising among the potential materials used for biomedical applications. However, few researchers have focused on their effects on analgesia. Despite the fact that various nanoparticles have been evaluated for drug delivery and MRI imaging contrast enhancement in clinical settings, no reports have investigated the in vivo synergy of ketorolac iron-oxide nanoparticle conjugates to improve the analgesic effect. METHODS: Ketorolac conjugated magnetic iron oxide nanoparticles (Keto-SPIO) were synthesized via two-stage additions of protective agents and chemical co-precipitation...

Background: Candida albicans is a major opportunistic fungal pathogen. One of the most important virulence factors that contribute to the pathogenesis of candidiasis is its ability to form biofilms. A key characteristic of Candida biofilms is their resistance to antifungal agents. Due to significant morbidity and mortality rates related to biofilm-associated drug resistance, there is an urgency to develop novel nanotechnology-based approaches preventing biofilm-related infections. Methods: In this study, we report, for the first time, the synthesis of selenium nanoparticles by irradiating selenium pellets by nanosecond pulsed laser ablation in liquid chitosan as a capping agent...

Mycobacterium abscessus (MAB ) is a rapidly emerging mycobacterial pathogen causing dangerous pulmonary infections. Because these bacteria are intrinsically multidrug resistant, treatment options are limited and have questionable efficacy. The current treatment regimen relies on a combination of antibiotics including clarithromycin paired with amikacin and either imipenem or cefoxitin. Tigecycline may be added when triple therapy is ineffective. We initially screened a library containing the majority of clinically available antibiotics for anti- MAB activity...

Aim Doxorubicin (Dox) is one of the most cardiotoxic anti-cancerous drug that is widely used for broad-range of cancers. There is an urgent need for developing cardio-oncological therapeutic interventions. Natural products having both anti-cancerous potential as well as cardioprotective effects may hold a great potential in this regard. Curcuma longa (an Indian herb) polyphenols including curcumin, and well known for its anti-oxidative and anti-cancerous potential was used in the present study for its synergistic effect on cancer cells and cardiomyocytes...

Over 50% of epithelial ovarian cancers express the BRCAness profile that leads to a dysfunctional homologous recombination repair system. The combination of a dysfunctional homologous recombination repair system and a poly (ADP-ribose) polymerase (PARP) inhibitor results in a synthetic lethal phenotype. The PARP inhibitor olaparib, approved as a monotherapy for patients with a germline BRCA mutation, has shown promising results in preclinical studies when combined with DNA damaging agents such as carboplatin...

The N17 region of gp41 in HIV-1 is the most conserved region in gp160. mRNA selection technologies were used to identify an Adnectin that binds to this region and inhibits gp41-induced membrane fusion. Additional selection conditions were used to optimize the Adnectin to greater potency (5.4 ± 2.6 nM) to HIV-1 and improved binding affinity to a N17-containing helical trimer (0.8 ± 0.4 nM). Resistance to this Adnectin mapped to a single Glu to Arg change within the N17 coding region. The optimized Adnectin (6200_A08) exhibited high potency and broad spectrum against 123 envelope proteins and multiple clinical isolate viruses, although certain envelope proteins did exhibit reduced susceptibility against 6200_A08 alone...

BACKGROUND: Chromosomal instability (CIN) is a common trait of cancer characterised by the continuous gain and loss of chromosomes during mitosis. Excessive levels of CIN can suppress tumour growth, providing a possible therapeutic strategy. The Mps1/TTK kinase has been one of the prime targets to explore this concept, and indeed Mps1 inhibitors synergise with the spindle poison docetaxel in inhibiting the growth of tumours in mice. METHODS: To investigate how the combination of docetaxel and a Mps1 inhibitor (Cpd-5) promote tumour cell death, we treated mice transplanted with BRCA1-/- ;TP53-/- mammary tumours with docetaxel and/or Cpd-5...

Acute myeloid leukemia (AML) is a major blood cancer with poor prognosis. New therapies are needed to target oncogene-driven leukemia stem cells, which account for relapse and resistance. Chromosome translocation t(8;21), which produces RUNX1-ETO (R-E) fusion oncoprotein, is found in ~13% AML. R-E dominance negatively inhibits global gene expression regulated by RUNX1, a master transcription factor for hematopoiesis, causing increased self-renewal and blocked cell differentiation of hematopoietic progenitor cells, and eventually leukemia initiation...
