Approaches Towards Endogenous Pancreatic Regeneration

The phenomenon of pancreatic regeneration in mammals has been well documented. It has been shown that pancreatic tissue is able to regenerate in several species of mammal after surgical insult. This tissue is also known to have the potential to maintain or increase its β-cell mass in response to metabolic demands during pregnancy and obesity. Since deficiency in β-cell mass is the hallmark of most forms of diabetes, it is worthwhile understanding pancreatic regeneration in the context of this disease. With this view in mind, this article aims to discuss the potential use in clinical strategies of knowledge that we obtained from studies carried out in animal models of diabetes. Approaches to achieve this goal involve the use of biomolecules, adult stem cells and gene therapy. Various molecules, such as glucagon-like peptide-1, β-cellulin, nicotinamide, gastrin, epidermal growth factor-1 and thyroid hormone, play major roles in the initiation of endogenous islet regeneration in diabetes. The most accepted hypothesis is that these molecules stimulate islet precursor cells to undergo neogenesis or to induce replication of existing β-cells, emphasizing the importance of pancreas-resident stem/progenitor cells in islet regeneration. Moreover, the potential of adult stem cell population from bone marrow, umbilical cord blood, liver, spleen, or amniotic membrane, is also discussed with regard to their potential to induce pancreatic regeneration

DESIGNING OF TEMPERATURE & HUMIDITY MONITORING EMBEDDED SYSTEMS

The places such as weather forecasting system, nuclear radiation measurement, greenhouses, agro-automation systems require real-time monitoring of environmental parameters like temperature and humidity. So a low-cost, low-power temperature and humidity sensor interfacing with embedded systems using PIC microcontroller and PLC is designed. The paper is analyzing the operating mechanism of DHT11 temperature and humidity combined sensor; where it features temperature and humidity sensor complex with calibrated digital signal output. The DHT11 sensor interfacing with controller is programmed, then the temperature and humidity acquisition program porting to embedded platform. Meanwhile, the data through human machine interface is intuitive feedback to the user
