Intermolecular interactions between salmon calcitonin, hyaluronate, and chitosan and their impact on the process of formation and properties of peptide-loaded nanoparticles.
(2014)The principal aim of this work was to study the formulation of a ternary complex comprising salmon calcitonin (sCT), hyaluronate (HA), and chitosan (CS) in a nanoparticle (NP) format. As interactions between the constituents ... -
miR-134 in extracellular vesicles reduces triple-negative breast cancer aggression and increases drug sensitivity
(2015)Exosomes (EVs) have relevance in cell-to-cell communication carrying pro- tumorigenic factors that participate in oncogenesis and drug resistance and are proposed to have potential as self-delivery systems. Advancing ... -
Matrix metalloproteinases in inflammatory bowel disease: an update
(2015)Matrix metalloproteinases (MMPs) are known to be upregulated in inflammatory bowel disease (IBD) and other inflammatory conditions, but while their involvement is clear, their role in many settings has yet to be determined. ... -
Mechanisms of aggregation inhibition by aspirin and nitrate-aspirin prodrugs in human platelets.
(2012)Objectives Aspirin is the mainstay of anti-platelet therapy in the secondary prevention of cardiovascular disease. However, problems with aspirin safety and resistance demand clinical strategies based on multiple pharmacological ... -
Predictive biomarkers for dasatinib treatment in melanoma
(2014)Dasatinib has anti-proliferative and anti-invasive effects in melanoma cell lines. However clinical trials have shown modest activity for dasatinib in metastatic melanoma. Although dasatinib targets SRC kinase, neither ... -
Metabolic syndrome: a closer look at the growing epidemic and its associated pathologies
(2015)Obesity is reaching epidemic proportions with recent worldwide figures estimated at 1.4 billion and rising year-on-year. Obesity affects all socioeconomic backgrounds and ethnicities and is a pre-requisite for metabolic ... -
miR-34a is an intracellular and exosomal predictive biomarker for response to docetaxel with clinical relevance to prostate cancer progression.
(2014)BACKGROUND Docetaxel-resistance limits successful treatment of castration resistant prostate cancer. We previously demonstrated that extracellular vesicles (exosomes) may play a role in regulating docetaxel resistance. ... -
Exosomes from triple-negative breast cancer cells can transfer phenotypic traits representing their cells of origin to secondary cells
(2013)Background Triple-negative breast cancer (TNBC) accounts for 15–20% of breast cancers but is responsible for a disproportionate number of deaths. We investigated the relevance, in TNBC, of nano-sized exosomes expelled ... -
Selective PKCalpha inhibition uncouples platelet angiogenesis promotion from collagen-induced aggregation
(2013)Platelets promote angiogenesis by releasing angiogenesis-regulating factors from their α-granules upon aggregation. This effect has both physiologic and pathologic significance as it may contribute to carcinogenesis. ... -
MMP inhibition by barbiturate homodimers
(2013)We have studied some homodimeric compounds derived from 5-homopiperazine substituted pyrimidine triones (barbiturates) with linkers in the range 2-20 carbon atoms. The compounds were designed to be capable of resisting ... -
Food supplement use in the community dwelling population aged 50 and over in the Republic of Ireland.
(2013)Summary Objective Use of food supplements in the developed world is increasing in all age groups. With older age, the prevalence of multimorbidity and pharmacotherapy increases. Aim was to explore the prevalence of food ... -
Co-spray dried carbohydrate microparticles: crystallisation delay/inhibition and improved aerosolization characteristics through the incorporation of hydroxypropyl-?-cyclodextrin with amorphous raffinose or trehalose
(2015)PURPOSE: To formulate and investigate the physicochemical properties, physical stability and aerosolization characteristics of nanoporous/nanoparticulate microparticles (NPMPs) prepared by co-spray drying the sugars ... -
Solubility of crystalline organic compounds in high and low molecular weight amorphous matrices above and below the glass transition by zero enthalpy extrapolation
(2014)Pharmaceutical applications which require knowledge of the solubility of a crystalline compound in an amorphous matrix are abundant in the literature. Several methods that allow the determination of such data have been ... -
The acoustic features of inhalation can be used to quantify aerosol delivery from a Diskus? dry powder inhaler
(2014)Some patients are unable to generate the peak inspiratory flow rate (PIFR) necessary to de-agglomerate drug particles from dry powder inhalers (DPIs). In this study we tested the hypothesis that the acoustic parameters of ... -
Dry powders for oral inhalation free of lactose carrier particles
(2014)Dry powder inhaler (DPI) products have traditionally comprised a simple formulation of micronised drug mixed with a carrier excipient, typically lactose monohydrate. The presence of the carrier is aimed at overcoming issues ... -
Superparamagnetic iron oxide nanoparticles (SPIONs)-loaded Trojan microparticles for targeted aerosol delivery to the lung
(2014)Targeted aerosol delivery to specific regions of the lung may improve therapeutic efficiency and minimise unwanted side effects. Targeted delivery could potentially be achieved with porous microparticles loaded with ... -
Bulk, surface properties and water uptake mechanisms of salt/acid amorphous composite systems
(2013)Developing amorphous pharmaceuticals can be desirable due to advantageous biopharmaceutical properties. Low glass transition temperature (Tg) amorphous drugs can be protected from crystallisation by mixing with high Tg ... -
Reducing mechanical activation-induced amorphisation of salbutamol sulphate by co-processing with selected carboxylic acids
(2013)The unintentional generation of amorphous character in crystalline active pharmaceutical ingredients (APIs) is an adverse consequence of mechanical activation during dosage form manufacture. In this study, we assess and ... -
Anti-inflammatory activity of ethanol extract and fractions from Couroupita guianensis Aublet leaves.
(2013)Abstract Ethnopharmacological relevance Couroupita guianensis Aublet, ‘macacarecuia’, ‘abricó-de-macaco’, ‘castanha-de-macaco’ and ‘amêndoa-dos-andes’, is found in tropical regions and is widely used in the treatment ...
