BACKGROUND: Amphilimus sirolimus-eluting stents (A-SES) represent a novel elution technology in the current era of drug-eluting stents with promising results in patients with diabetes mellitus. At present no large trial has been designed to evaluate clinical outcomes of A-SES as compared to new-generation drug-eluting stents in unselected patients. Accordingly, we designed this trial to evaluate clinical noninferiority of A-SES as compared with zotarolimus-eluting stents (ZES) in a real-world, all-comers setting...

After the introduction of drug eluting stent (DES) the rate of in-stent restenosis (ISR) has decreased if compared to the BMS era; however, treatment of patients with ISR remained a major issue for the interventional cardiologist. DES has been largely used with good results also as second layer for the treatment of ISR, but the overall percentage of patients suffering from restenosis still remains high, especially in some subgroups of patients as ones with diabetes mellitus (DM). In this clinical scenario, drug coated balloon (DCB) has been gaining an important role for the treatment of ISR...

Regulatory agencies from all over the world have set up stringent guidelines with regard to drug degradation products due to their toxic effects or carcinogenicity. Lansoprazole, a proton-pump inhibitor, was subjected to forced degradation studies as per ICH guidelines Q1A (R2). The drug was found to degrade under acidic, basic, neutral hydrolysis and oxidative stress conditions, whereas it was found to be stable under thermal and photolytic conditions. The chromatographic separation of the drug and its degradation products were achieved on a Hiber Purospher, C18 (250 X 4...

Hepatocellular carcinoma (HCC) is the third most frequent cause of cancer deaths worldwide. The standard of care for intermediate HCC is transarterial chemoembolization, which combines tumour embolization with locoregional delivery of the chemotherapeutic doxorubicin. Embolization therapies induce hypoxia, leading to the escape and proliferation of hypoxia-adapted cancer cells. The transcription factor that orchestrates responses to hypoxia is hypoxia-inducible factor 1 (HIF-1). The aim of this work is to show that targeting HIF-1 with combined drug therapy presents an opportunity for improving outcomes for HCC treatment...

Paclitaxel (PTX) incorporation in poly (lactic acid-co-glycolic acid) (PLGA) matrices produce films with high tensile rigidity and slow release that fail to deliver the required release rate for most biomedical applications such as in drug eluting stents and cancer treatments. To modify and improve this behavior, a set of poly (diol sebacate)s were synthesized and fully characterized as possible additives. The tensile properties of PLGA blends were evaluated as these materials could be used as coatings in drug eluting stent applications...

A novel quantification approach, compensating for the effect of gradient elution on the instrumental response during reversed phase high-performance liquid chromatography - inductively coupled plasma - tandem mass spectrometry analysis, has been developed and validated. As a proof of concept, diclofenac and its related compounds, including its major metabolite i.e. 4'-hydroxy-diclofenac, have been quantitatively determined in human plasma matrix. An inductively coupled plasma - tandem mass spectrometer has been applied for the interference-free determination of Cl as (35)ClH2(+) using H2 as a reaction gas in the collision/reaction cell...

Chronic kidney disease (CKD) exacerbating vascular disease poses a major challenge to nephrology. Surgically placed vascular fistulas, as an aid to hemodialysis prior to kidney transplant, have extended many lives, while post-surgical restenosis closure of the fistula by smooth muscle cells affects many lives. When post-surgical restenosis is developed, palliative measures are almost always surgical: there are no effective drug treatments. In this study, we offer a testable hypothesis that effects of CKD on widely distributed vascular diseases and the phenomenon of fistula restenosis are both driven by the pathologic creation of non-dividing smooth muscle cells via asymmetric division of exponentially increasing metakaryotic stem cells...

Antibiotic loaded bone cements are used as drug delivery systems for the treatment of periprosthetic joint infections. They can be loaded with antibiotics during industrial component production (premixing) and during cement preparation (manually blending). Although double premixed antibiotic loaded bone cements are available, manually blending of a gentamicin premixed antibiotic loaded bone cement with vancomycin is still popular. We compared in vitro antibiotic elution and compressive strength of 0.5 g gentamicin premixed bone cement (PALACOS® R + G), 0...

Historically, coronary artery bypass graft (CABG) surgery has been the standard revascularization method for unprotected left main coronary artery (LMCA) disease. Over the last decade, several randomized controlled trials (RCTs) have shown favorable results for percutaneous coronary intervention (PCI) with drug-eluting stent (DES) compared with CABG; however, no RCT has been conducted directly comparing DESs with medical therapy alone (MTA). Furthermore, the 2 most recently reported larger RCTs, using new-generation DESs reached somewhat conflicting conclusions comparing the 2 revascularization strategies...

This study evaluated the midterm delivery of doxorubicin in liver specimens from patients (N = 4) with hepatocellular carcinoma treated with drug-eluting embolic (DEE) transarterial chemoembolization. The patients had surgical resection 57, 79, 80 and 105 days after doxorubicin DEE chemoembolization. Doxorubicin concentrations inside embolic particles and in surrounding tissues were assessed by infrared microspectroscopy and microspectrofluorimetry, respectively. Embolic particles still contained doxorubicin and provided sustained drug delivery within targeted tissues 80 days after chemoembolization...
