The transcription factors Pdx1 and Oc1 are co-expressed in multipotent pancreatic progenitors (MPCs), but their expression patterns diverge in hormone-expressing cells, with Oc1 expression being extinguished in the endocrine lineage and Pdx1 being maintained at high levels in β cells. We previously demonstrated that cooperative function of these two factors in MPCs is necessary for proper specification and differentiation of pancreatic endocrine cells. In those studies, we observed a persistent decrease in expression of the β-cell maturity factor MafA...

BACKGROUND: Environmental stressors that encounter in early-life and cause abnormal fetal and/or neonatal development may increase susceptibility to non-communicable diseases such as diabetes. Maternal exposure to ambient fine particulate matter (PM2.5) is associated with various fetal abnormalities, suggesting that it may program offspring's susceptibility to diabetes. In the present study, we therefore examined whether maternal exposure to diesel exhaust PM2.5 (DEP), one of the major sources of ambient PM2...

PURPOSE: Inverse planning is trial-and-error iterative process. This work introduces a fully automated inverse optimization approach, where the treatment plan is closely tailored to the unique patient anatomy. The auto-optimization is applied to pancreatic stereotactic body radiotherapy (SBRT). MATERIALS AND METHODS: The automation is based on stepwise reduction of dose-volume histograms (DVHs). Five uniformly spaced points, from 1% to 70% of the organ at risk (OAR) volumes, are used...

OBJECTIVES: To measure the usefulness of Ki-67 proliferative index (Ki-67 index) as a prognostic variable for grading pancreatic neuroendocrine tumors. METHODS: A multi-institutional prospective database comprising 350 patients. Grading based on mitotic activity (<2 mitoses/10 high-power fields, 2-20 and >20) and Ki-67 index (<3% per 10 high-power fields, 3%-20% and >20%). Final grade selected based on higher grade of either variable. RESULTS: Most patients were in the less than 3% (n = 158) and 3% to 20% Ki-67 category (n = 107), with a minority being high-grade (Ki-67 > 20%, n = 27)...

BACKGROUND: Cone beam computed tomography (CBCT) for radiotherapy image guidance suffers from respiratory motion artifacts. This limits soft tissue visualization and localization accuracy, particularly in abdominal sites. We report on a prospective study of respiratory motion-corrected (RMC)-CBCT to evaluate its efficacy in localizing abdominal organs and improving soft tissue visibility at end expiration. MATERIAL AND METHODS: In an IRB approved study, 11 patients with gastroesophageal junction (GEJ) cancer and five with pancreatic cancer underwent a respiration-correlated CT (4DCT), a respiration-gated CBCT (G-CBCT) near end expiration and a one-minute free-breathing CBCT scan on a single treatment day...

In the differential diagnosis of biliary obstruction with unknown etiology, biliary fascioliasis should be considered in endemic and nonendemic regions. After diagnostic evaluation, endoscopic retrograde cholangiopancreatography (ERCP) was performed for etiological evaluation and/or treatment of biliary obstruction in five patients with a mean age of 55.8 years. Endoscopic sphincterotomy and cholangiogram revealed linear filling defects in the biliary system. Fasciola hepatica parasites were extracted using balloon and basket catheters in two and three patients, respectively...

Temporin A (FLPLIGRVLSGIL-NH2 ), temporin F (FLPLIGKVLSGIL-NH2 ), and temporin G (FFPVIGRILNGIL-NH2 ), first identified in skin secretions of the frog Rana temporaria, produced concentration-dependent stimulation of insulin release from BRIN-BD11 rat clonal β-cells at concentrations ≥1 nM, without cytotoxicity at concentrations up to 3 μM. Temporin A was the most effective. The mechanism of insulinotropic action did not involve an increase in intracellular Ca2+ concentrations. Temporins B, C, E, H, and K were either inactive or only weakly active...

OBJECTIVE: PET/CT imaging with 68Ga-1,4,7,10-tetraazacyclododecane-N,N',N″,N‴-tetraacetic acid-D-Phe1-Tyr3-octreotide (DOTATOC) is useful in patients with neuroendocrine tumors (NETs). Functioning NETs by definition secrete abnormal levels of hormones, causing clinical symptoms. It is known that physiologic accumulation can be seen in some organs, but it remains unknown whether elevated hormone levels can affect the physiologic accumulation pattern of 68Ga-DOTATOC. We aimed to investigate the influence of higher hormone levels on physiologic accumulation of 68Ga-DOTATOC...

BACKGROUND: With the improvement of the surgical technique of Laparoscopic pancreaticoduodenectomy (LPD), indications will be extended to patients with vascular invasion. With LPD, vascular grafts for reconstruction are more frequently needed because adequate mobilization is not always done and vascular grafts can safely facilitate reconstruction. We describe our experience of reconstruction with the falciform ligament. METHODS: Venous reconstruction is performed after removal of the specimen...

Interfacial engineering approaches have been used to design functional foods so as to control lipase-induced digestion of emulsified lipids and release of bioactive lipophilic components in the gastrointestinal tract. In this study, emulsion droplets with the interface stabilized with gum Arabic (GA) and whey protein isolate (WPI) were prepared by mixing or sequential adsorption. WPI/GA intramolecular soluble complexes (ISCs) have superior emulsifying properties in stabilizing oil-in-water emulsions. The impact of the interfaces for WPI/GA ISC-layered (one-layered) and double-layered emulsions formed by sequential deposition of WPI or GA on the lipolysis of emulsions was investigated using an in vitro simulated gastrointestinal model...

Recombinant adeno-associated virus (rAAV)-mediated gene delivery shows promise to transduce the pancreas, but safety/efficacy in a neoplastic context is not well established. To identify an ideal AAV serotype, route, and vector dose and assess safety, we have investigated the use of three AAV serotypes (6, 8, and 9) expressing GFP in a self-complementary (sc) AAV vector under an EF1α promoter (scAAV.GFP) following systemic or retrograde pancreatic intraductal delivery. Systemic delivery of scAAV9.GFP transduced the pancreas with high efficiency, but gene expression did not exceed >45% with the highest dose, 5 × 1012 viral genomes (vg)...

Activation of PI3K/AKT pathway occurs frequently in tumors and is correlated with radioresistance. The PI3K/AKT pathway can be an important target for improvement of radiotherapy. Although adding of chemotherapy to radiation therapy regimen enhances survival in patients with locally advanced pancreatic cancer, more effective therapies for increasing radiosensitivity are urgently needed. In this study, we investigated whether the novel PI3K inhibitor HS-173 could attenuate radiation-induced up-regulation of DNA damage repair processes and assessed its efficacy as a radio- and chemo-sensitizer...
