Autoimmune Thyroid Disease Genes Identified in Non-Caucasians  [PDF]
Yoshihisa Ban, Yoshiyuki Ban, Yoshio Ban
Open Journal of Endocrine and Metabolic Diseases (OJEMD) , 2012, DOI: 10.4236/ojemd.2012.24017
Abstract: Autoimmune thyroid diseases (AITDs), including Graves’ disease (GD) and Hashimoto’s thyroiditis (HT), are among the commonest autoimmune disorders, affecting approximately 2% - 5% of the population. Epidemiological data support strong genetic influences on the development of AITD. The identification of genes placing individuals at an increased risk for the development of AITD has been a slow process. However, over the last 20 years or so real progress has been made with the mapping of novel loci, via a number of different approaches. The first AITD gene discovered, Human Leucocyte Antigen (HLA)/Major Histocompatibility Complex (MHC), is associated with both GD and HT. Non-MHC genes that confer susceptibility to AITD can be classified into two groups: (1) immune-regulatory genes (e.g., CD40, CTLA-4, and PTPN22); (2) thyroid-specific genes—thyroglobulin and TSH receptor genes. These genes interact with environmental factors, such as infection, likely through epigenetic mechanisms to trigger disease. In this review, we will summarize the latest findings on AITD susceptibility genes in non-Caucasians.
Weak Values Influenced by Environment  [PDF]
Masashi Ban
Journal of Modern Physics (JMP) , 2013, DOI: 10.4236/jmp.2013.411A1001

A weak value of an observable is studied for a quantum system which is placed under the influence of an environment, where a quantum system irreversibly evolves from a pre-selected state to a post-selected state. A general expression for a weak value influenced by an environment is provided. For a Markovian environment, the weak value is calculated in terms of the predictive and retrodictive density matrices, or by means of the quantum regression theorem. For a non-Markovian environment, a weak value is examined by making use of exactly solvable models. It is found that although the anomalous property is significantly suppressed by a Markovian environment, it can survive a non-Markovian environment.

Formation of Photosensitizing Crystalline C60 Particles by Ink-Jet Method  [PDF]
Masahito Ban, Fusako Sasaki
World Journal of Nano Science and Engineering (WJNSE) , 2012, DOI: 10.4236/wjnse.2012.22014
Abstract: The crystalline fullerene C60 particles were formed and immobilized on poly(dimethylsiloxane) (PDMS) substrates under the various discharge conditions by an ink-jet method, and investigated for the reactive oxygen species (ROS) generation property under visible light irradiation. The particles were synthesized by discharging a toluene solution dissolved C60 and poly(methyl methacrylate) (PMMA) with the ink-jet spotting system. The ROS generation was evaluated by comparisons of the fluorescence intensities measured for the formed particles under green laser irradiation and in a dark room using fluorescent dyes, 2’,7’-dichlorofluorescein diacetate and dihydroethidium. The results of transmission electron microscope (TEM) observation showed that the formed particles consisted of crystalline C60. The optimal ink-jet discharge conditions for synthesizing the particles to generate more ROS were found. In the case of the optimal conditions, the structure in which the needle-like particles were three-dimensionally formed was confirmed. The surface area of the crystalline C60 particles was calculated using the SEM observation results, and it was suggested that when the needle-like finer particles were three-dimensionally formed under the optimal conditions, increasing the surface area lead to an increase in the ROS generation amount.
The Green Sustainable Economic Development Model under Sustainable Use of Energy and Pollution Control  [PDF]
Wanping Yang, Lan Ban
Theoretical Economics Letters (TEL) , 2013, DOI: 10.4236/tel.2013.31004

As concerns about energy and environment emerge the concept of sustainable development, this paper develops a five-sector endogenous technological change economic growth model considering sustainable use of energy and pollution control. We introduce energy and environment into production function and utility function, solve the conditions for sustainable economic growth with the optimal control method, further reveal the dynamic relationship which should be met by energy consumption rate, pollution control and sustainable economic growth, prove the possibility of sustainable economic growth and reveal the path and conditions of sustainable economic growth under the dual constraints of energy and environment.

The Power of Change-Point Test for Two-Phase Regression  [PDF]
To Van Ban, Nguyen Thi Quyen
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.519286
Abstract: In this paper, the roughness of the model function to the basis functions and its properties have been considered. We also consider some conditions to take the limit of the roughness when the observations are i.i.d. An explicit formula to calculate the power of change-point test for the two phases regression through the roughness was obtained.
Genetic Factors of Autoimmune Thyroid Diseases in Japanese
Yoshiyuki Ban
Autoimmune Diseases , 2012, DOI: 10.1155/2012/236981
Abstract: Autoimmune thyroid diseases (AITDs), including Graves’ disease (GD) and Hashimoto’s thyroiditis (HT), are caused by immune response to self-thyroid antigens and affect approximately 2–5% of the general population. Genetic susceptibility in combination with external factors, such as smoking, viral/bacterial infection, and chemicals, is believed to initiate the autoimmune response against thyroid antigens. Abundant epidemiological data, including family and twin studies, point to a strong genetic influence on the development of AITDs. Various techniques have been employed to identify genes contributing to the etiology of AITDs, including candidate gene analysis and whole genome screening. These studies have enabled the identification of several loci (genetic regions) that are linked to AITDs, and, in some of these loci, putative AITD susceptibility genes have been identified. Some of these genes/loci are unique to GD and HT and some are common to both diseases, indicating that there is a shared genetic susceptibility to GD and HT. Known AITD-susceptibility genes are classified into three groups: HLA genes, non-HLA immune-regulatory genes (e.g., CTLA-4, PTPN22, and CD40), and thyroid-specific genes (e.g., TSHR and Tg). In this paper, we will summarize the latest findings on AITD susceptibility genes in Japanese. 1. Introduction Autoimmune thyroid diseases (AITDs) are common autoimmune endocrine diseases [1], and according to one study, AITD are the commonest autoimmune diseases in the USA [2]. Even though the hallmark of AITD is infiltration of the thyroid with thyroid reactive lymphocytes, the end result is two clinically opposing syndromes: Hashimoto’s thyroiditis (HT) manifesting by hypothyroidism and Graves’ disease (GD) manifesting by hyperthyroidism. In HT, the lymphocytic infiltration of the thyroid gland leads to apoptosis of thyroid cells and hypothyroidism [3]. In contrast, in GD, the lymphocytic infiltration of the thyroid leads to activation of TSH-receptor- (TSHR) reactive B cells that secrete TSHR-stimulating antibodies causing hyperthyroidism [4]. GD and HT are complex diseases, and their etiology involves both genetic and environmental influences [1]. Up until 15 years ago, the only known gene for AITD was HLA-DR3 haplotype (DRB1*03-DQB1*02-DQA1*0501) in Caucasians. However, with the advent of new genomic tools and the completion of the human genome and the HapMap projects, new non-HLA genes have been identified and their functional effects on disease aetiology started to be dissected as well. This paper will summarize the recent advances

Theoretical and Applied Economics , 2007,
Abstract: An essential element of the sales promotion strategy and not only is the evaluation of the results obtained from the activities performed. Due to their nature and applicability, the evaluation of the sales promotion is much easier to be achieved, but it raises some problems. Using a hypothetical example, we have tried to develop a "classic" evaluation model of the specialty literature.

Abstract: The image of a destination is more than a distinguishing element; it is a component of the supply and brings more value to it. The image of a destination can be the decisive component, while the other elements re relatively alike (1). The image of a tourist destination is strongly connected to the image of a country, the image of a nation and the image of a place. The image of a place is formed for a receiver naturally by accumulating experiences with that place, the use of the sources of personal and impersonal information. For the transmitter, the image is the result of some direct and indirect actions. The branding of the place is the conscientious and coordinated process of an image achievement. In the paper there are presented some examples of actions of image research, an essential step having in view the branding or re-branding It is presented a study of the citizens of Oradea regarding their perception of tourist Romania.
