Some aspects of visual functions and serum retinol levels in young adults and middle aged subjects

The comparism of the dark adaptation and plasma retinol level (Vitamin A) was a potentially useful method of studying the basic nature of the aging process in vision. The purpose of this study was to determine the effect of age upon the dark adaptation time and plasma retinol level. Dark adaptation time, visual fields and plasma retinol levels were studied in two different age groups of Myanmar subjects (young adults: 18-25 years and middle-aged subjects: 40-60 years) (n=30 each). Dark adaptation time (DAT) was determined by a rapid dark adaptation test adopted from Thornton (1977). Visual field was assessed by manually setting kinetic perimetry. Plasma retinol level was determined by colorimetric method using trifluoroacetic acid (TFA). None of the subjects exhibited subnormal plasma retinol levels. Although the plasma retinol levels of middle-aged subjects were comparable to those of their younger counterparts (66.3 (5.2) µg/dl vs 61.4(8.1) µg/dl) (mean(SD)), the middle-aged subjects had significantly longer DAT (5.7 (1.4) vs 3.6 (1.3) minutes; P<0.05) and significantly greater reduction (P<0.05) in visual fields of both eyes. There was a significant negative correlation (P<0.05) between plasma retinol level and DAT in the middle-aged subjects, but not in young adults. No correlation was found between serum retinol level and visual field reduction in both groups. Even with comparable plasma retinol level, longer DAT and greater reduction of visual field in middle-aged subjects indicated that retinal function might also be affected by the age-related changes in retina.

EFFECT OF WASHING ON DELTAMETHRIN CONCENTRATION AND BIO-EFFICACY OF INSECTICIDE-TREATED MOSQUITO NETS

The deltamethrin impregnated mosquito nets not only prevent but also control malaria, dengue fever and other vector-bone diseases. However, the deltamethrin concentration and bio-efficacy of mosquito nets can reduce due to washing. The purpose of this study is to investigate the effect of washing on deltamethrin concentration and bio-efficacy of military insecticide-treated mosquito nets. High Performance Liquid Chromatography method was used for the determination of deltamethrin in mosquito-nets. Then, the WHO recommended cone and excito-chamber methods were used to determine the bio-efficacy of mosquito nets. The deltamethrin concentrations in the mosquito-net were after no wash (4590±58.54 ppm), 1× wash (4020±47.39 ppm), 2× wash (3225±45.22 ppm), 3× wash (2771±107.5 ppm), 4× wash (2657±58.59 ppm), 5× wash (1835±47.55 ppm), 10× wash (957±34.85 ppm), 15× wash (197±22.54 ppm) and 20× wash (87±23.75 ppm). The mosquito knockdown effects were reduced by washing of net (no wash to 20× wash) after 60 minutes and 6 hours exposure range from 90-40% and 100-70%. The mosquito mortality rate was reduced by washing of net (no wash to 20× wash) after 24 hours exposure were reduced range from 100-80%. The mosquito repellent action was reduced by washing of net (no wash to 20× wash) after 10 minutes and 24 hours exposure, range from 90-30% and 100-60%. The effective bio-efficacy level was found in 5×wash (1835±47.55 ppm of deltamethrin).Therefore, mosquito net should be impregnated again after the 5× wash to obtain the best protection on the public from mosquito bite

The Development and Growth of Tissues Derived From Cranial Neural Crest and Primitive Mesoderm Is Dependent on the Ligation Status of Retinoic Acid Receptor γ: Evidence That Retinoic Acid Receptor γ Functions to Maintain stem/progenitor Cells in the Absence of Retinoic Acid

An important study demonstrating how retinoic acid receptor gamma plays a key role in tissue formation and regenerationFinal publication is available from Mary Ann Liebert, Inc., publishers http://dx.doi.org/10.1089/scd.2014.0235Retinoic acid (RA) signaling is important to normal development. However, the function of the different RA receptors (RARs)--RARα, RARβ, and RARγ--is as yet unclear. We have used wild-type and transgenic zebrafish to examine the role of RARγ. Treatment of zebrafish embryos with an RARγ-specific agonist reduced somite formation and axial length, which was associated with a loss of hoxb13a expression and less-clear alterations in hoxc11a or myoD expression. Treatment with the RARγ agonist also disrupted formation of tissues arising from cranial neural crest, including cranial bones and anterior neural ganglia. There was a loss of Sox 9-immunopositive neural crest stem/progenitor cells in the same anterior regions. Pectoral fin outgrowth was blocked by RARγ agonist treatment. However, there was no loss of Tbx-5-immunopositive lateral plate mesodermal stem/progenitor cells and the block was reversed by agonist washout or by cotreatment with an RARγ antagonist. Regeneration of the caudal fin was also blocked by RARγ agonist treatment, which was associated with a loss of canonical Wnt signaling. This regenerative response was restored by agonist washout or cotreatment with the RARγ antagonist. These findings suggest that RARγ plays an essential role in maintaining stem/progenitor cells during embryonic development and tissue regeneration when the receptor is in its nonligated state

Sediment Yield Simulation in Upper Ayeyarwady Basin

This study was undertaken to examine the applicability of Soil and Water Assessment Tool (SWAT) model for the Upper Ayeyarwady Basin for simulating sediment yield. The SWAT model is hydro-dynamic and physically-based model for the application in complex and large basins. The required input data for this study were Digital Elevation Model (DEM) with spatial resolution of 30 m x 30 m, land use/land cover map and soil map. And also the hydro-meteorological data around the basin were used. The model has been calibrated and validated using observed sediment data of eight years at the basin outlet (Sagaing). The automated calibration process was used to calibrate the model parameters using time series data from 2003 to 2007. Data from 2008 to 2010 were used to validate the model using the input parameter set. The model predicted the annual sediment in the watershed as 272.8 million ton per year. The average annual values of sediment yield for Nash-Sutcliffe efficiency (NSE) and R2 were found to be 0.89 and 0.82, respectively for calibration and 0.88 and 0.80, respectively for validation, which were within the allowable limit.

Evaluation of physicochemical characteristics and genetic diversity of widely consumed rice varieties in Kyaukse area, Myanmar

Consumer preferences are greatly influenced by eating and cooking qualities of rice grains, along with the economic value of a specific rice variety. This study was to evaluate ten rice varieties including the check variety IR64 on their physicochemical, cooking and eating qualities as well as to identify their genetic diversity using SSR markers. Most rice varieties are medium-grain types based on length-breadth ratio, whereas the famous Myanmar rice variety, Paw San Bay Kyar, (PSBK) is bold. PSBK showed the best cooking and eating quality traits with intermediate amylose content (AC), intermediate gelatinization temperature (GT), soft gel consistency (GC), and the highest elongation ratio among the studied rice varieties. Seventeen SSR markers linked with cooking and eating traits were used to assess the extent of polymorphism and genetic variation among ten rice varieties. There were 49 alleles in total, with an average of 2.88 alleles per locus. RM592 had the maximum number of alleles. The average PIC value ranged from 0.22 (RM540) to 0.77 (RM592). Cluster analysis with UPGMA method based on Jaccard’s similarity coefficient divided ten rice varieties into two main groups and four sub-clusters. In multiple regression analysis, RM190 and Wx primers were discovered to be significantly associated with AC, GC and GT of cooking and eating quality traits. This study could contribute to the choice of rice varieties with superior cooking and eating qualities for rice breeding programs by implementing physicochemical characteristics and molecular analysis

A Study of Learning Environment for Initiating Flutter App Development Using Docker

The Flutter framework with Dart programming allows developers to effortlessly build applications for both web and mobile from a single codebase. It enables efficient conversions to native codes for mobile apps and optimized JavaScript for web browsers. Since utilizing a wide range of widgets in Flutter ensures consistent experiences on various devices for users, it becomes crucial in programming education by providing a unified environment for learning app development while reducing the need for platform-specific knowledge. However, the setup of the Flutter environment is challenging for novice students due to its multiple steps, such as installing dependencies and configuring environments. To support independent learning for these students, it is essential to simplify the setup by providing user-friendly instructions and automated tools. In this paper, we present a Docker-based environment for Flutter app developments across Windows, Linux, and Mac through Visual Studio Code, ensuring a unified learning experience. This paper aims to simplify complex configurations and address the obstacles encountered by students when initiating Flutter projects. For the evaluation, we prepared three simple Flutter projects along with the setup environment in a Docker container. Then, we asked 24 Master's students at Okayama University, Japan, to install the environment and modify the source codes in the projects independently by following the given instructions. The results show that all the students successfully completed the assignments, which confirms the efficiency and validity of our proposal
