Alginate and chitosan are polysaccharides that are widely used in the biomedical field, especially as wound dressings. Controlled bioadhesion is an advanced functionality that offers the potential to reduce injuries due to the stripping-off of the biomaterial. Herein, we report the efficient grafting of poly-N(isopropylacryamide) (PNIPAM), a thermosensitive polymer that exhibits a lower critical solution temperature (LCST) at 32 °C on the alginate/chitosan polyelectrolyte complex (PEC) surface.

Assessing the response of pancreatic islet cells to glucose stimulation is important for understanding β-cell function. Zebrafish are a promising model for studies of metabolism in general, including stimulus-secretion coupling in the pancreas. We used transgenic zebrafish embryos expressing a genetically-encoded Ca sensor in pancreatic β-cells to monitor a key step in glucose induced insulin secretion; the elevations of intracellular [Ca].

Purpose: Time of flight (TOF) PET reconstruction is well known to statistically improve the image quality compared to non-TOF PET. Although TOF PET can improve the overall signal to noise ratio (SNR) of the image compared to non-TOF PET, the SNR disparity between separate regions in the reconstructed image using TOF data becomes higher than that using non-TOF data. Using the conventional ordered subset expectation maximization (OS-EM) method, the SNR in the low activity regions becomes significantly lower than in the high activity regions due to the different photon statistics of TOF bins.

Motor neuron and pancreas homeobox 1-antisense RNA1 (MNX1-AS1) is a novel long noncoding RNA and has been suggested to be overexpressed in human ovarian cancer and glioma. The role of MNX1-AS1 in lung cancer was still unknown. In our study, we observed levels of MNX1-AS1 expression through analyzing The Cancer Genome Atlas and found MNX1-AS1 expression was highly expressed in lung adenocarcinoma tissues compared with normal lung tissues, but there was no statistical difference between lung squamous cell carcinoma tissues and normal lung tissues.

Despite the conformality of modern X-ray therapy limiting high dose received by normal tissues the physical properties of X-rays make it impossible to avoid dose being delivered distal to the target. This "exit dose" is likely clinically significant especially for patients with gastrointestinal (GI) cancers when considering that even low dose received by the heart, lungs, bowel, and other radiosensitive structures can lead to morbidity and even may affect long-term tumor control. In contrast, proton beam therapy (PBT) delivers no "exit dose" and a growing body of literature suggests that this may improve clinical outcomes by reducing toxicity and even allowing for safe dose intensification to enhance tumor control.

Diabetes mellitus is a multifactorial disease affecting increasing numbers of patients worldwide. Progression to insulin-dependent diabetes mellitus is characterized by the loss or dysfunction of pancreatic β-cells, but the pathomechanisms underlying β-cell failure in type 1 diabetes mellitus and type 2 diabetes mellitus are still poorly defined. Regeneration of β-cell mass from residual islet cells or replacement by β-like cells derived from stem cells holds great promise to stop or reverse disease progression. Read More

Whereas genomic aberrations in the SLIT-ROBO pathway are frequent in pancreatic ductal adenocarcinoma (PDAC), their function in the pancreas is unclear. Here we report that in pancreatitis and PDAC mouse models, epithelial Robo2 expression is lost while Robo1 expression becomes most prominent in the stroma. Cell cultures of mice with loss of epithelial Robo2 (Pdx1;Robo2) show increased activation of Robo1 myofibroblasts and induction of TGF-β and Wnt pathways. Read More

Being highly expressed in insulinomas, the glucagon-like peptide-1 receptor (GLP-1R) is a potential target for diagnosis, localization and treatment with the radiolabeled GLP-1R agonist exendin. Tracer accumulation in the kidneys, however, hampers accurate diagnostic visualization of pancreatic tissue and prohibits the therapeutic application of radiolabeled exendin for beta-cell-derived tumors. Therefore, we evaluated the ability of succinylated gelatin (Gelofusine) to reduce the renal accumulation of radiolabeled exendin in humans and we performed dosimetric calculations to estimate the maximum absorbed insulinoma dose that could be achieved when exendin would be used for peptide receptor radionuclide therapy.

The commonly used sedative α-adrenoceptor agonist dexmedetomidine has adverse cardiovascular effects in dogs that can be prevented by concomitant administration of the peripherally acting α-adrenoceptor antagonist MK-467. An ancillary effect of dexmedetomidine is to decrease insulin release from the pancreas, whereas MK-467 stimulates insulin release. This study assessed the effects of co-administered dexmedetomidine and MK-467 in a canine glibenclamide-induced hypoglycaemia model. Read More
