The understanding of fast folding dynamics of single α-helices comes mostly from studies on rationally designed peptides displaying sequences with high helical propensity. The folding/unfolding dynamics and energetics of α-helix conformations in naturally occurring peptides remains largely unexplored. Here we report the study of a protein fragment analogue of the C-peptide from bovine pancreatic ribonuclease-A, RN80, a 13-amino acid residue peptide that adopts a highly populated helical conformation in aqueous solution...

BACKGROUND: Pancreatic cancer is the fourth leading cause of cancer-related death in Europe and the United States. Studies have demonstrated that patients with pancreatic cancer have a high prevalence of pain, with rates varying from 47% to 82%. Analgesia using intrathecal drug delivery systems (IDDS) has been poorly studied specifically in this population. METHODS: The IDDS for pancreatic cancer pain was a follow-up observational study designed to evaluate 11-year results of IDDS for refractory pancreatic cancer pain at the Institut de Cancérologie de L'Ouest, Paul Papin in France...

Diabetes distress (DD), or psychological fatigue associated with diabetes management, is common in type 1 and 2 diabetes mellitus and is associated with poor glycemic control. DD has never been evaluated in patients undergoing total pancreatectomy with islet autotransplant (TPIAT) for chronic pancreatitis. We analyzed DD after TPIAT in 260 patients (average age 34.3 [standard deviation 15], 75.5% F) undergoing TPIAT between 2006 and 2014. Each patient completed one or more diabetes distress scale (DDS) questionnaires from 1 to 7 years post-TPIAT (631 total)...

Introduction: In Japan, the age of patients with pancreatic cancer has increased. Combination chemotherapies such as 5-fluorouracil/leucovorin, oxaliplatin and irinotecan therapy and gemcitabine hydrochloride (GEM) +nab paclitaxel therapy have been developed as the standard treatments for young patients with advanced recurrent pancreatic cancer. However, both therapies produce toxicity and their administration is limited by the patients' age or performance status. The efficacy and safety data obtained in the GEST study-a large-scale randomised controlled study conducted in patients with pancreatic cancer in Japan-suggested that GEM +S-1 (GS) combination therapy is a promising candidate for those aged between 75 and 80 years...

Pancreatic cancer is characterized by mutated signaling pathways and a high incidence of drug resistance. Comprehensive, large-scale proteomic analysis can provide a system-wide view of signaling networks, assist in understanding drug mechanisms of action and interactions, and serve as a useful tool for pancreatic cancer research. In this study, liquid chromatography-mass spectrometry-based proteomic analysis was applied to characterize the combination of gemcitabine and birinapant in pancreatic cancer cells, which was shown previously to be synergistic...

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy characterized by early invasiveness and resistance to treatment. Surgery in early stages is the only effective treatment, thus finding new biomarkers for the early detection of PDAC remains a major challenge. The present study aimed to compare the immunoproteome between PDAC patients and healthy controls using serological proteome analysis method. Firstly, cell lysates from two different pancreatic cancer cell lines were separated by two dimensional (2D) gels, and then transferred onto membranes probed with sera from 20 PDAC patients and 10 healthy controls...

Acute pancreatitis has numerous etiologies, with the most common including gallstones, alcohol abuse, and medications such as angiotensin-converting enzyme (ACE) inhibitors, statins, and diuretics. Mirtazapine has been associated with increased serum cholesterol and serum triglyceride levels. However, few studies have reported dangerously elevated triglyceride levels resulting in acute pancreatitis. This report discusses a case of mirtazapine-induced pancreatitis in a 46-year-old African American female. The patient presented to the emergency department with pancreatitis, presumably alcohol-induced as with a prior admission, but she denied any recent alcohol use...

PURPOSE: Previous studies demonstrated the utility of [18 F]fluoropropyl-(+)-dihydrotetrabenazine ([18 F]FP-(+)-DTBZ) as a positron emission tomography (PET) radiotracer for the vesicular monoamine transporter type 2 (VMAT2) to quantify beta cell mass in healthy control (HC) and type 1 diabetes mellitus (T1DM) groups. Quantification of specific binding requires measurement of non-displaceable uptake. Our goal was to identify a reference tissue (renal cortex or spleen) to quantify pancreatic non-specific binding of [18 F]FP-(+)-DTBZ with the inactive enantiomer, [18 F]FP-(-)-DTBZ...

BACKGROUND/OBJECTIVES: Total pancreatectomy with islet autotransplantation (TPIAT) is considered for managing chronic pancreatitis in selected patients when medical and endoscopic interventions have not provided adequate relief from debilitating pain. Although more centers are performing TPIAT, we lack large, multi-center studies to guide decisions about selecting candidates for and timing of TPIAT. METHODS: Multiple centers across the United States (9 to date) performing TPIAT are prospectively enrolling patients undergoing TPIAT for chronic pancreatitis into the Prospective Observational Study of TPIAT (POST), a NIDDK funded study with a goal of accruing 450 TPIAT recipients...

Experimental models of neuroendocrine tumour disease are scarce, and no comprehensive characterisation of existing gastroenteropancreatic neuroendocrine tumour (GEPNET) cell lines has been reported. In this study, we aimed to define the molecular characteristics and therapeutic sensitivity of these cell lines. We therefore performed immunophenotyping, copy number profiling, whole-exome sequencing and a large-scale inhibitor screening of seven GEPNET cell lines. Four cell lines, GOT1, P-STS, BON-1 and QGP-1, displayed a neuroendocrine phenotype while three others, KRJ-I, L-STS and H-STS, did not...

Glucagonoma is an extremely rare tumor of the pancreatic alpha-cells. Its estimated annual incidence is 1 case per 20 million individuals. Necrolytic migratory erythema (NME) is the hallmark clinical sign. We report a patient with normoglycemic glucagonoma and NME. A 44-year-old male patient presented with a 4-year history of unexplained exanthema and unintentional weight loss. Skin examination revealed a mildly pruritic rash on the trunc, the extremities and the face (fig 1). One found erythematous polycyclic migratory lesions with scaling and crusting margins and central resolution...

BACKGROUND: Literature increasingly supports the inverse relationship of vitamin D (VitD) level and type 2 diabetes (T2DM). Proposed protective mechanisms of VitD include its anti-inflammatory effects, increased insulin secretion via pancreatic β-cell stimulation, and downregulation of parathyroid hormone levels. Interventional studies show mixed results of VitD therapy in prediabetic patients with VitD deficiency or diabetic patients with normal VitD levels. STUDY QUESTION: Does high-dose VitD replacement improve glycemic control and microalbuminuria (MAU) in uncontrolled T2DM and concurrent VitD deficiency? STUDY DESIGN: This placebo-controlled, double-blinded study randomized 30 subjects aged 30-65 years with an elevated HbA1c level of 7...

Major part of a pancreatic islet is composed of β-cells that secrete insulin, a key hormone regulating influx of nutrients into all cells in a vertebrate organism to support nutrition, housekeeping or energy storage. β-cells constantly communicate with each other using both direct, short-range interactions through gap junctions, and paracrine long-range signaling. However, how these cell interactions shape collective sensing and cell behavior in islets that leads to insulin release is unknown. When stimulated by specific ligands, primarily glucose, β-cells collectively respond with expression of a series of transient Ca2+ changes on several temporal scales...

Following the recent introduction of a stronger regimen for pancreatic carcinoma, patients undergoing chemotherapy present high incidences of fatigue. The feasibility and validity of evaluating fatigue by questionnaire for patients with unresectable pancreatic cancer (URPC) receiving this recent regimen of chemotherapy remains unclear. Enrolled patients completed the Functional Assessment of Cancer Therapy-Fatigue questionnaire (FACIT-F, version 4), a questionnaire regarding additional concerns, a numerical rating scale test concerning loss of appetite, an evaluation of degree of pain and sensory disorder, and the Patient Neurotoxicity Questionnaire (PNQ) before undergoing nab-paclitaxel plus gemcitabine therapy...
