Open Journal of Endocrine and Metabolic Diseases (OJEMD) , 2012, DOI: 10.4236/ojemd.2012.23007
Abstract: Intrduction: Edema, Hypertension and Hypokalemia occur with inhibition of 11 B-Hydroxysteroid Dehydrogenase Type 2 (11B-HSD2) by chronic Licorice ingestion. However, a similar presentation following a chronic use of another commonly used sweetener “Stevia” is not reported. Objective: To document a first case report of a subject presenting with Edema, Prehypertension and Hypokalemia induced by 11B-HSD2 inhibition induced by chronic ingestion of sweetener stevia. Case Report: 32 year old Caucasian woman presented with generalized edema (feet, hands and face) of over 6 months. She was noted to also manifest Prehypertension (138/88 mmHg) and Hypokalemia (3.4 mM/l). Laboratory tests revealed decline in serum aldosterone and plasma renin activity, an increase in plasma cortisol/cortisone ratio. On persistent interrogation, patient admitted to daily consumption of sweetener stevia for over 9 months. All the presenting manifestations resolved with normalization of the laboratory tests on withdrawal of stevia. Conclusion: This case report indicates that chronic ingestion of sweetener stevia may induce edema, hypertension and hypokalemia via reduced conversion of cortisol into cortisone by inhibition of 11 B-Hydroxysteroid Dehydrogenase Type 2.
Exploration of potassium chloride from Khur Playa

Acta Montanistica Slovaca , 2008,
Abstract: The Great Kavir is located in the centre and extended to the eastern part of Iran. The low rainfall (86.5 mm/yr) and highevaporation (2857 mm/yr) in this region have led to the presence of a number of playas. This study summarizes the most important andeconomical minerals such as halite and potash which are deposited in the Great Kavir, especially in Khur Playa. There is thus a strongmotivation for extracting this material. The evaporate minerals precipitating from the playa brine are influenced by the progressivechange in brine salinity and its composition.Research was then undertaken to elaborate a common extraction method based on a programmed scheme. A series of test-pits andboreholes were drilled in the playa to a depth of maximum 63 m to produce brine. The pre-constructed ponds were then used to extractKCl by evaporation of water under the sun. Our investigations show that the average content of potassium at Khur Playa is at least2600 ppm.
Algorithm Acceleration and Data Storage Volume Reduction in Reliability Modeling Within Distribution Network

Research Journal of Applied Sciences, Engineering and Technology , 2013,
Abstract: Investigation and assessment of a system performance was complex. So Equipment reliability modeling may be a proper solution to easier it. Electricity distribution network is among systems reliability of which is of great importance. They are highly complex due to their large size and hence their modeling takes a long time. This study offers a simple algorithm for Electricity distribution networks modeling which enjoys algorithm high speed and data low volume. It is based on a graph search method called coloring. In this innovative method, it is suggested to search minimal path from the beginning of the feeder to the sink points .Also it is applied by saving paths in terms of switches and through logical operations of symmetric difference without searching paths from each input to estimate minimal path between all inputs and outputs. In so doing there will be no need for explicitly defining the source node, as it is easily recognizable via junction matrix composition. This kind of network modeling is so flexible and it is simply applicable to bidirectional or non-planar graphs.
Comparison of Gridded Precipitation Time Series Data in APHRODITE and Asfazari Databases within Iran’s Territory  [PDF]

Atmospheric and Climate Sciences (ACS) , 2013, DOI: 10.4236/acs.2013.32025

The V1003R1 version of the monthly, seasonal and annual precipitation time series of the Middle East APHRODITE database and Asfazari database within Iranian territory in the time interval 1961 and 2004 were compared with each other. The monthly, seasonal and annual time series of the both databases in most cases show a random behavior and the time series follow a similar pattern with a significant autocorrelation of both databases. Studying cross-correlation between the time series of the two bases indicate that the zero lag significance in the monthly, seasonal and annual time series statistically confirm the coincidence of the peak and fall in the time series of both bases. Wilcoxon Test with 95% confidence confirms significance of the mean difference of the two series. However, there is not enough evidence to confirm the null hypothesis suggesting lack of difference between means of the two series. The statistical-objective analysis of the two bases’ time series indicates that although the series follow a similar course, the estimated precipitation quantity in monthly, seasonal and annual time series of APHRODITE base, except in several monthly time series and in trivial quantities, has been less than the estimated precipitation of Asfazari bases, but the amount of the difference was not constant and did not follow a regular pattern, although this difference has been narrowed in recent years.

Abstract: Dust phenomenon is one of the biggest environmental problems in arid and semiarid regions. In these areas, lakes and wetlands are natural dust traps and core sampling method can be an appropriate way to assess the phenomenon of the dust. Therefore, the purpose of this study is the study of frequency and characteristics of dust sediments in core samples from Hashilan wetlands, Kermanshah. Four intact core samples were taken from different parts of the Hashilan wetland in Kermanshah. Physical, chemical and micromorphological analysis were done. Also clay mineralogy was performed using X-ray analysis (XRD) and shape of particles was photographed by scanning electron microscope (SEM). Considering that four samples had been taken from different parts of the wetland, the quantitative differences in dust amount are likely due to the location of the samples. The results of XRD and thin sections show that the dominant mineralogical composition of dust particles was clay minerals, quartz and calcite. SEM results for core sample 1 revealed that most particles had the size between 2 to 50 mm which ranged from fine silt to coarse silt. Considering the similarities between SEM images for core sample 1 and those from Kermanshah dust measurement station, it could be said that fine rounded particles detected at top 30 cm of core samples had Aeolian origin. These findings were in accordance with the results from dust measurement and weather station of Kermanshah about increased dust activities in the study area over past 10 years.

Journal of Diabetes Mellitus (JDM) , 2018, DOI: 10.4236/jdm.2018.84015
Abstract: Background: The major effect of Exenatide is attributed to lowering of post-prandial glycemia, whereas insulin glargine mainly improves fasting glycemia [FPG]. Objective: Therefore, we assessed effect of Exenatide administration at 6 months and for at 1 year on glycemic control, lipids, body weight [BW], daily insulin dose and hypoglycemic events. Methods: Records of 164 subjects, 126 men and 38 women administered Exenatide between January 2011 and December 2013 are included in this report. Exenatide was initiated at 5 mcg subcutaneously twice daily [BID] in obese subjects, BMI > 30 kg/m2, with C-peptide > 1 ng/d, and HbA1c 7.5% - 9.5%, while receiving daily metformin 2000 mg, Sulfonylurea Glimepiride 8 mg and insulin Glargine [GLAR]. Exclusion criteria were creatinine > 1.5 mg/dL and liver enzymes > 2.5 times upper limit of normal. Indices of glycemic control include fasting plasma glucose levels and HbA1c. Lipids include serum concentrations of total, LDL and HDL cholesterol. Other endpoints are body weight, daily insulin dose and number of hypoglycemic events per patient during 4 weeks prior to initiation of Exenatide, at 6 months and 1 year of therapy. Results: In 37 subjects, Exenatide was discontinued within 1 - 3 weeks; 29 due to onset of nausea and vomiting. Seven of these also complained of abdominal pain and in these, serum amylase and lipase were elevated indicating presence of acute pancreatitis. One subject discontinued because of chest pain. Fasting plasma Glucose remained unchanged following Exenatide administration. However, HbA1c declined significantly denoting improvement in overall glycemic control without significant changes in body weight, daily insulin dose and hypoglycemic events. Lipid panel improved as well. Conclusion: Exenatide may be an appropriate

Abstract: We deposited silicon carbide thin layers on cleaned Si (100) substrates using the plasma enhanced chemical vapor deposition method, and show that the RFTIR spectrum is periodic in the near and medium infrared ranges. It is shown that both the deposition rate and the uniformity of the thin films are decreased by increasing the substrate temperature, and that the refractive index is increased by increasing the substrate temperature. This shows that there is a trade-off between the quality improvement of the uniformity and refractive index.
