Gastrointestinal neuroendocrine tumors (GI-NETs) are rare neoplasms, like all NETs. However, the incidence of GI-NETS has been increasing in recent years. Gastric NETs (G-NETs) and duodenal NETs (D-NETs) are the common types of upper GI-NETs based on tumor location. G-NETs are classified into three distinct subgroups: type I, II, and III. Type I G-NETs, which are the most common subtype (70%-80% of all G-NETs), are associated with chronic atrophic gastritis, including autoimmune gastritis and Helicobacter pylori associated atrophic gastritis...

The prevalence of factors that are associated with an increased risk of stent thrombosis (ST), including smoking, diabetes mellitus, and small stent size, is different in women and men who underwent percutaneous coronary intervention. Thus, gender may potentially modify the relation between stent type and the incidence of ST during long-term follow-up. We explored the data of Patient Related Outcomes With Endeavor Versus Cypher stenting Trial (PROTECT) to evaluate this hypothesis. PROTECT randomized 2,061 women and 6,648 men who underwent percutaneous coronary intervention for various indications to Endeavor zotarolimus-eluting stenting (E-ZES) or Cypher sirolimus-eluting stenting (C-SES)...

OBJECTIVE: To review primary literature of gastric acid suppressive agents and vitamin B12 deficiency. DATA SYNTHESIS: From the published articles, proton pump inhibitors (PPIs) are associated with a higher risk of inducing vitamin B12 deficiency than histamine-2 receptor antagonists (H2RAs). Literature suggests that there is an increased risk of developing vitamin B12 deficiency in patients who are exposed to extended durations of therapy with PPIs. There are, however, some conflicting data in elderly patients suggesting that the PPI use for more than 3 years does not increase the risk of vitamin B12 deficiency...

Well-differentiated neuroendocrine tumor (WDNET) of the stomach can arise in three distinct clinical settings: (1) in association with autoimmune atrophic gastritis, (2) in association with multiple neuroendocrine neoplasia type I (MEN I) or Zollinger-Ellison syndrome (ZES), or (3) sporadic. The Ki-67 proliferative index (PI) in gastric WDNETs in these three distinct clinical settings has not been evaluated in detail. Forty-five gastric WNETs underwent polypectomy (n = 4), endoscopic mucosal resection (n = 12), and surgical resection (n = 29) between 1994 and 2015 were included...

BACKGROUND: Pancreatic endocrine tumors (PETs) are rare and can occur as part of neurofibromatosis type 1 (NF1). Gastrinomas are functional PETs that are rarely associated with NF1. Only two cases of their occurrence have been reported in the literature. CASE REPORT: A 28-year-old woman was admitted for further evaluation of epigastric soreness, heartburn, nausea, vomiting, diarrhea, and a significant weight loss. Physical examination was remarkable for cutaneous findings (axillary freckling and multiple café-au-lait spots) as well as neurofibromas (dermal, plexiform)...

BACKGROUND: Coatings consisting of a polymer and drug are widely used in drug-eluting stents (DES) and are essential in providing programmable drug release kinetics. Among other factors, stent coating technologies can influence blood compatibility, affect acute and sub-acute healing, and potentially trigger a chronic inflammatory response. OBJECTIVE: The aim of this study was to investigate the short-term (7 and 28 days) and long-term (90 and 180 days) coating integrity of the Xience Prime Everolimus-Eluting Stent (EES), Resolute Zotarolimus-Eluting Stent (ZES), Taxus Paclitaxel-Eluting Stent (PES), and Nobori Biolimus A9-Eluting Stent (BES) in a rabbit ilio-femoral stent model...

Gastrinoma is a very rare tumor leading to gastrin hypersecretion and characterised by Zollinger-Ellisson syndrome (ZES) i.e. severe gastric and duodenal ulceration and profuse diarrhea. This disease can be sporadic or familial within a multiple endocrine neoplasia type 1 (MEN-1) syndrome. Diagnosis is based on hypergastrinemia/hypercholrhydria. Tumors are usually located in the duodeno-pancreas. Preoperative tumor location by CT, echoendoscopy and fibroscopy is not always possible because of the small size of the lesion that are frequently multiple...

BACKGROUND: Both bare-metal stents (BMS; the first-generation coronary stent) and zotarolimus-eluting stents (ZES; a second-generation drug-eluting stent [DES]) have been widely utilized to treat coronary heart disease. However, the long-term comparative effectiveness of BMS and ZES remains unclear. The purpose of this study was to evaluate long-term comparative effectiveness of BMS versus ZES. METHODS: We created a longitudinal database by linking the New York State (NYS) cardiac registries, statewide hospital discharge data, the National Death Index (NDI), and the U...

Epilepsy, one of the most frequent neurological disorders, is still insufficiently treated in about 30% of patients. As a consequence, identification of novel anticonvulsant agents is an important issue in medicinal chemistry. In the present article we report synthesis, physicochemical, and pharmacological evaluation of N-trans-cinnamoyl derivatives of R and S-2-aminopropan-1-ol, as well as R and S-2-aminobutan-1-ol. The structures were confirmed by spectroscopy and for derivatives of 2-aminopropan-1-ols the configuration was evaluated by means of crystallography...

AIM: Chronic kidney disease (CKD) is a powerful predictor of major cardiovascular events and stent thrombosis (ST) in patients undergoing percutaneous coronary interventions (PCI). No randomized data are available to compare, and guide the selection of type of stent between bare metal (BMS) or drug eluting stent (DES) in this population. METHODS AND RESULTS: We performed a post-hoc analysis of the PROlonging Dual antiplatelet treatment after Grading stent-induced Intimal hyperplasia studY (PRODIGY) trial, in which stable or unstable patients with coronary artery disease undergoing PCI were randomized 1:1:1:1 to receive BMS, paclitaxel- (PES), zotarolimus- (ZES-S), or everolimus- (EES) eluting stent...

We present detailed results on the effect of chain branching on the topological properties of entangled polymer melts via an advanced connectivity-altering Monte Carlo (MC) algorithm. Eleven representative model linear, short-chain branched (SCB), and long-chain branched (LCB) polyethylene (PE) melts were employed, based on the total chain length and/or the longest linear chain dimension. Directly analyzing the entanglement [or the primitive path (PP)] network of the system via the Z-code, we quantified several important topological measures: (a) the PP contour length Lpp, (b) the number of entanglements Zes per chain, (c) the end-to-end length of an entanglement strand des, (d) the number of carbon atoms per entanglement strand Nes, and (e) the probability distribution for each of these quantities...
