n-3 Polyunsaturated fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have protective effects against the pancreatic β-cell dysfunction through several mechanisms. Thiazolidines are insulin sensitizers and are used in treating patients with type 2 diabetes. Our previous study demonstrated that a combination of fish oil, which is rich with EPA and DHA, and pioglitazone exerts beneficial effects on obesity and diabetes through their actions on the liver and adipose tissue. However, it remains largely unknown whether such combination therapy affects the pancreas...

Purpose: In diabetes, pancreatic beta cell mass declines significantly prior to onset of fasting hyperglycemia. This decline may be due to endoplasmic reticulum (ER) stress, and the system L amino acid transporter LAT1 may be a biomarker of this process. In this study, we used 5-(2- (18)F-fluoroethoxy)-L-tryptophan ( (18)F-L-FEHTP) to target LAT1 as a potential biomarker of beta cell function in diabetes. Procedures: Uptake of (18)F-L-FEHTP was determined in wild-type C57BL/6 mice by ex vivo biodistribution...

For over a decade, excess body weight, commonly categorized as overweight (body mass index, BMI: 25.0 to 29.9 kg/m2) and obesity (BMI: ≥ 30 kg/m2) has been an established incidence risk factor for several adult cancers (1). For 2012, the burden of disease attributed to elevated BMI was estimated as nearly half-million new cancers worldwide, making this the third highest ranked cancer risk factor globally after smoking and infections (ranked second in most western populations) and an important public health problem (2, 3)...

Sericin has been implicated in lower cholesterolemic effect due to its properties with several mechanisms. Mitochondria are one of the most important targets to be affected in high blood cholesterol and glucose conditions. The protective role of sericin on mitochondria remains doubtful. To examine this role, electron microscopic, histopathologic, immunohistochemical, and biochemical studies were performed in a high-cholesterol diet/streptozotocin rat model. The results demonstrated that sericin reduced blood cholesterol without hypoglycemic effect...

Cytomegaloviruses (CMVs) establish persistent, systemic infections and cause disease by maternal-fetal transfer, suggesting that their dissemination is a key target for anti-viral intervention. Late clinical presentation has meant that human CMV dissemination is not well understood. Murine CMV provides a tractable model. Whole mouse imaging of virus-expressed luciferase has proved a useful way to track systemic infections. MCMV, in which the abundant lytic gene M78 was luciferase tagged via a self-cleaving peptide (M78-LUC), allowed serial, unbiased imaging of systemic and peripheral infection without significant virus attenuation...

Organoids have the potential to bridge 3D cell culture to tissue physiology by providing a model resembling in vivo organs. Long-term growing organoids were first isolated from intestinal crypt cells and recreated the renewing intestinal epithelial niche. Since then, this technical breakthrough was applied to many other organs, including prostate, liver, kidney and pancreas. We describe here how to apply a SILAC-based quantitative proteomic approach to measure protein expression changes in intestinal organoids under different experimental conditions...

The purpose of this work was to systematically assess the impact of the b-value on texture analysis in MR diffusion-weighted imaging (DWI) of the abdomen. In eight healthy male volunteers, echo-planar DWI sequences at 16 b-values ranging between 0 and 1000 s/mm(2) were acquired at 3 T. Three different apparent diffusion coefficient (ADC) maps were computed (0, 750/100, 390, 750 s/mm(2) /all b-values). Texture analysis of rectangular regions of interest in the liver, kidney, spleen, pancreas, paraspinal muscle and subcutaneous fat was performed on DW images and the ADC maps, applying 19 features computed from the histogram, grey-level co-occurrence matrix (GLCM) and grey-level run-length matrix (GLRLM)...

BACKGROUND: Interleukin-4 (IL-4) together with interleukin-13 (IL-13) play an important role in inflammation and wound repair, and are known to be upregulated in human skeletal muscle after strenuous physical exercise. Additionally, these cytokines may act as autocrine growth factors in pancreatic cancer cells. We hypothesize that IL-4, IL-13, and their corresponding receptors are involved in mechanism of cancer cachexia. METHODS: Tissue samples from human skeletal muscle, white fat, liver, healthy pancreas, and pancreatic ductal adenocarcinoma were analyzed by quantitative real-time polymerase chain reaction for mRNA expression levels of IL-4, IL-13, IL-4 receptor α, and IL-13 receptor α1...

BACKGROUND: The relationship between chronic pancreatitis (CP) and subsequent pyogenic liver abscess (PLA) is not well understood. METHODS: We investigated the risk of PLA in patients with CP using inpatient claims data from the Taiwan National Health Insurance Program for the period 2000-2010, we identified 17,810 patients with chronic pancreatitis (CP group) and 71,240 patients without CP (non-CP group). Both cohorts were followed until a diagnosis of PLA, until they were censored from the study because of loss to follow-up, death, or termination of insurance, or until the study cut-off date of December 31, 2011...

Cancer handles an estimated 7.6 million deaths worldwide per annum. A recent theory focuses on the role Cancer Stem Cells (CSCs) in driving tumorigenesis and disease progression. This theory hypothesizes that a population of the tumor cell with similar functional and phenotypic characteristics as normal tissue stem cells are responsible for formation and advancement of many human cancers. The CSCs subpopulation can differentiate into non-CSC tumor cells and promote phenotypic and functional heterogeneity within the tumor...

The aim of this study was to evaluate two research hypotheses: H0-the embryonic pancreas in grass snakes develops in the same manner as in all previously investigated amniotes (from three buds) and its topographical localization within the adult body has no relation to its development; H1-the pancreas develops in a different manner and is related to the different topography of internal organs in snakes. For the evaluation of these hypotheses we used histological methods and three-dimensional (3D) reconstructions of the position of the pancreatic buds and surrounding organs at particular developmental stages and of the final position and shape of the pancreatic gland...

PURPOSE: Inadequate analgesia following abdominal surgery may affect outcome. Data in patients undergoing liver surgery suggested that postoperative coagulopathy might delay epidural catheter removal. Thus, alternative analgesic techniques should be evaluated. METHODS: We compared the analgesic efficacy of intraoperative intrathecal morphine [single injection 4 µg/kg before skin incision (ITM group, n = 23)] to intravenous opioids [iv remifentanil infusion during surgery followed by i...

BACKGROUND: Diabetes mellitus (DM) is a complex disease with alterations in metabolic and inflammatory markers. Stillman Salgado rats (eSS) spontaneously develop type 2 DM by middle age showing progressive impairment of glucose tolerance with hyperglycemia, hypertriglyceridemia and hyperinsulinemia. We analyzed the effects of supplementation of ω-3 and ω-6 polyunsaturated fatty acids (PUFAs) with or without nordihydroguaiaretic acid (NDGA) added, an antioxidant and lipoxygenase inhibitor, on metabolic and inflammatory parameters in eSS rats to evaluate whether they can delay development and/or prevent progression of DM...
