BACKGROUND: Although drug-eluting stents have dramatically reduced the rates of restenosis and target lesion revascularization, they are associated with stent thrombosis (ST), a catastrophic event likely due to delayed endothelialization and chronic inflammation caused by the polymer and the metal scaffolds. To increase the safety and efficacy of stents, polymer-free dual drug-eluting stents (DDES) have been developed. METHODS: A total 160 stents (Bare-metal stents (BMS), polymer-free probucol stents (PrES), sirolimus-eluting stents (SES) and DDES) were randomly implanted in the coronary arteries of 80 pigs...

Over two decades have passed since posterior reversible encephalopathy syndrome (PRES) was first described in 1996. It has becoming increasingly recognised because of improved and more readily available imaging modality. The exact pathophysiological mechanism is not completely understood and remains controversial at present. Precise diagnosis is essential to guide prompt, proper management. Our ability of differentiating it from other acute neurological disorders is likely to improve as we learnt more about the spectrum of this entity in the last 20 years...

This study examines the role of Polycomb repressive complex 1 (PRC1) at active genes. The PRC1 and PRC2 complexes are crucial for epigenetic silencing during development of an organism. They are recruited to Polycomb response elements (PREs) and establish silenced domains over several kilobases. Recent studies show that PRC1 is also directly recruited to active genes by the cohesin complex. Cohesin participates broadly in control of gene transcription, but it is unknown whether cohesin-recruited PRC1 also plays a role in transcriptional control of active genes...

Renal function impairment in lung cancer patients with bone metastases was investigated, as this can limit the application of bisphosphonates representing the gold standard in the management of such cases. Clinicopathological data of 570 lung cancer patients were retrospectively analysed for changes in renal function parameters. Co-morbidities included hypertension (50%), COPD (33%) and diabetes mellitus (15%). Statistical analysis was performed with Fisher's exact tests and a Cox proportional hazards model...

Myriads of biological processes occur in or at cellular lipid membranes. Knowledge about the localization of proteins, lipids, and other molecules within biological membranes is thus crucial for the understanding of such processes. Here, we present a method to determine the immersion depths of lipid carbon atoms in membranes by paramagnetic relaxation enhancement (PRE) caused by the presence of doxylated lipids. As membrane mimetics, we employ small isotropic bicelles made of synthetic lipids and of natural Escherichia coli phospholipid extract...

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological syndrome, usually reversible, characterized by vasogenic oedema in cerebral posterior regions in patients with autoimmune diseases, nephropathies, hypertensive crisis, eclampsia and exposure to cytotoxic drugs. The main symptoms are: headache, nausea, vomiting, seizures, visual disturbance and altered consciousness. Complications as cerebral hemorrhage and recurrences are rare. We describe a case of a 65 years old woman, affected by chronic kidney disease, recently exacerbated, diabetes and hypertension in treatment, who showed an heterogeneous clinical presentation with vomiting, headache, blurred vision and impaired consciousness during an episode of acute hypertension...

The Hepatitis B virus (HBV) envelope glycoproteins are essential for viral entry into the hepatocyte and are also targets for host immune response. The study of these proteins could allow us to highlight molecular hot points influencing HBV fitness, which would subsequently modify the clinical evolution of the disease, both under anti-viral therapy or without treatment. The present short communication underlines the importance of the high variability in HBV envelope proteins, in regard with the literature and in our hands, for HBV-infected patients either on anti-HBV treatment or not...

Few studies have investigated posterior reversible encephalopathy syndrome (PRES) in patients with chronic renal failure (CRF). The present study analyzed the clinical manifestations, laboratory examinations and imaging features of PRES in patients with CRF. A total of 42 patients with CRF with or without PRES were recruited in the current retrospective case-control study. Patient data taken prior to the onset of PRES in patients with CRF and PRES (n=21) were collected and analyzed. At the same time, data from patients with CRF but without PRES (n=21) were also analyzed...

Progesterone is essential for pregnancy maintenance and menstrual cycle regulation. Hormone action has been primarily ascribed to the well-characterized classical signaling pathway involving ligand binding, activation of nuclear progesterone receptors (PRs), and subsequent activation of genes containing progesterone response elements (PREs). Recent studies have revealed progesterone actions via non-classical signaling pathways, often mediated by non-genomic signaling. Progesterone signaling, in conjunction with growth factor signaling, impacts on the function of growth factors and regulates important physiological actions such as cell growth and remodeling, as well as apoptosis...

This report presents the case of a 60-year-old woman who was diagnosed with stage IV lung adenocarcinoma with asymptomatic brain metastases and commenced chemotherapy with cisplatin/pemetrexed (CDDP/Pem). She experienced tonic-clonic convulsions on day 9 of the first cycle, which were accompanied by increased blood pressure (173/69 mm Hg) and headache. Therefore, brain MRI was performed to check for stroke or progression of brain metastatic foci. T2-weighted, FLAIR, and ADC map images showed high-intensity areas in the subcortical region of the bilateral parieto-occipital lobes, leading to a diagnosis of posterior reversible encephalopathy syndrome (PRES)...
