Reliable continuous glucose monitoring (CGM) enables a variety of advanced technology for the treatment of type 1 diabetes. In addition to artificial pancreas algorithms that use CGM to automate continuous subcutaneous insulin infusion (CSII), CGM can also inform fault detection algorithms that alert patients to problems in CGM or CSII. Losses in infusion set actuation (LISAs) can adversely affect clinical outcomes, resulting in hyperglycemia due to impaired insulin delivery. Prolonged hyperglycemia may lead to diabetic ketoacidosis-a serious metabolic complication in type 1 diabetes...

A 73-year-old man was referred for F-FDG PET/CT study for staging of biopsy-proven pancreatic adenocarcinoma. The scan demonstrated focal intense FDG uptake in the pancreatic head, localizing the primary tumor. Additional moderate diffuse uptake was seen throughout the pancreas, suggestive of acute pancreatitis. Concurrent diagnostic CT showed diffuse pancreatic hypoenhancement consistent with edema. Serum lipase level was elevated, confirming a diagnosis of acute pancreatitis.

A 69-year-old woman had gradually worsening abdominal discomfort over a year. A pancreatic mass was revealed by abdominal CT. The patient underwent FDG PET/CT for staging, which demonstrated the hypermetabolic pancreatic mass with multiple liver metastases. The lesion was pathologically confirmed as pancreatic adenosquamous carcinoma after biopsy.

Shi Wei, Gene P Siegal
It has long been known that some cancers have the propensity to metastasize to certain organs thus creating a nonrandom distribution of sites for distant relapse, a phenomenon known as "metastatic organotropism." Some of these examples include ovary primary to abdominal cavity, prostate primary to bone, and pancreas primary to liver. In contrast, other tumor types, such as mammary and renal cell carcinoma, can relapse in multiple organs although approximately half of advanced breast cancers metastasize to bone...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary form of kidney disease. Clinical data on this multisystem disorder are scarce from developing countries. We conducted a prospective observational study of the clinical profile of ADPKD patients at a single center over a period of six years. A total of 208 patients were studied. Majority were male (60.6%) and the mean age was 45.8 ± 14.5 years. About 61.5% had early stage (Stages 1-3) of chronic kidney disease (CKD) and 38.5% had advanced CKD (Stages 4 and 5)...

A sensitive fluorescence sensor for warfarin was proposed via quenching the fluorescence of l-tryptophan due to the interaction between warfarin and l-tryptophan. Warfarin, as one of the most effective anticoagulants, was designed and synthesized via lipase from porcine pancreas (PPL) as a biocatalyst to catalyze the Michael addition of 4-hydroxycoumarin to α, β-unsaturated enones in organic medium in the presence of water. Furthermore, the spectrofluorometry was used to detect the concentration of warfarin with a linear range and detection limit (3σ/k) of 0...

Mast cells (MC) are hemopoietically-derived tissue immune cells that are ubiquitous in the body, including neuroendocrine organs such as the hypothalamus, pineal, pituitary, ovaries, pancreas and uterus where their action is not well understood. Mast cells have historically been associated with allergies because of their rich content of histamine and tryptase, but more recently with regulation of immunity and inflammation due their synthesis and release of numerous cytokines and chemokines. Mast cells are located perivascularly and express numerous receptors for diverse ligands such as allergens, pathogens, neurotransmitters, neuropeptides and hormones including acetylcholine, calcitonin gene-related peptide (CGRP), corticosteroids, corticotropin-releasing hormone (CRH), β-endorphin, epinephrine, 17β-estradiol, gonadotrophins, hemokinin-A (HKA), leptin, melatonin, neurotensin (NT), parathyroid hormone (PTH), substance P (SP) and vasoactive instestinal peptide (VIP)...

Objectives Platynosomum species are cat-specific parasitic trematodes that parasitize the biliary ducts and gall bladder. Due to the common connection to the major duodenal papilla of the pancreas and common bile ducts in addition to the periductal proximity of the pancreas, it is possible that platynosomosis could cause pancreatitis. The objective of this study was to determine whether platynosomosis, a commonly diagnosed parasitic disease in cats on St Kitts, has any association with pancreatic disease. Methods To investigate this possibility, the pancreas of free-roaming cats with naturally acquired platynosomosis were evaluated via ultrasound, serum concentrations of feline pancreatic lipase (fPL), cobalamin, folate and feline trypsin-like immunoreactivity (fTLI) and histopathology...

Glucagon-like peptide-1 (GLP-1) is an incretin hormone which stimulates insulin release and inhibits glucagon secretion from the pancreas in a glucose-dependent manner. Incretin-based therapies, consisting of GLP-1 receptor (GLP-1R) agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors, are used for the treatment of T2D. Immunohistochemical studies for GLP-1R expression have previously been hampered by the use of unspecific polyclonal antibodies. This study used a new monoclonal antibody to assess GLP-1R expression in pancreatic tissue from 23 patients with T2D, including 7 with a DPP-4 inhibitor and 1 with a GLP-1R agonist treatment history...

In vivo evaluation of [(18)F]BMS-754807 binding in mice and rats using microPET and biodistribution methods is described herein. The radioligand shows consistent binding characteristics, in vivo, in both species. Early time frames of the microPET images and time activity curves of brain indicate poor penetration of the tracer across the blood brain barrier (BBB) in both species. However, microPET experiments in mice and rats show high binding of the radioligand outside the brain to heart, pancreas and muscle, the organs known for higher expression of IGF1R/1R...

Pentachlorophenol (PCP) was used in large quantities, and mainly for killing the intermediate host snails of schistosome in China, thereby resulting in ubiquitous PCP residue in the environment. However, studies considering the carcinogenicity of PCP for humans mainly focused on occupational workers, and the actual carcinogenicity of PCP for general population is uncertain. To investigate the association between cancer risks and PCP exposure in a community population, an ecological study was conducted in three contaminated areas along the Yangtze River...

Tumor spread along nerves, a phenomenon known as perineurial invasion, is common in various cancers including pancreatic ductal adenocarcinoma (PDAC). Neural invasion is associated with poor outcome, yet its mechanism remains unclear. Using the transgenic Pdx-1-Cre/KrasG12D /p53R172H (KPC) mouse model, we investigated the mechanism of neural invasion in PDAC. To detect tissue-specific factors that influence neural invasion by cancer cells, we characterized the perineurial microenvironment using a series of bone marrow transplantation (BMT) experiments in transgenic mice expressing single mutations in the Cx3cr1, GDNF and CCR2 genes...

: Contemporary and future outpatient long-term artificial pancreas (AP) studies need to cope with the well-known large intra- and inter-day glucose variability occurring in type 1 diabetic (T1D) subjects. Here we propose an adaptive Model Predictive Control (MPC) strategy to account for it and test it in silico. METHODS: A Run-to-Run (R2R) approach adapts the subcutaneous basal insulin delivery during the night and the carbohydrate-to-insulin ratio (CR) during the day, based on some performance indices calculated from subcutaneous continuous glucose sensor data...

Even though ellagic acid has previously been valued in many models of cancer, so far its full mechanistic effect as a natural antiapoptotic agent in the prevention of type 2 diabetes complications has not been completely elucidated, which was the goal of this study. We fed albino rats a high-fat fructose diet (HFFD) for 2 months to induce insulin resistance/type 2 diabetes and then treated the rats with ellagic acid (10 mg/kg body weight, orally) and/or repaglinide (0.5 mg/kg body weight, orally) for 2 weeks...

IgG4-related disease (IgG4-RD) is a fibroinflammatory disease of unknown etiology, which is characterized by a tendency to form tumefactive lesions, increased serum levels of IgG4, and massive infiltration of IgG4-positive plasma cells with storiform fibrosis and/or obliterative phlebitis. Patients with IgG4-RD have frequently multiorgan involvements such as the pancreas, biliary tree, salivary glands, periorbital tissues, kidneys, lungs, lymph nodes, and retroperitoneum. IgG4-RD mainly affects middle-aged to elderly men except for involvement in lachrymal and salivary glands, so-called Mikulicz's disease...
