Tsong-Rong Jang, Ching-Lin Wu, Chai-Ming Chang, Wei Hung, Shih-Hua Fang, Chen-Kang Chang
Journal of the International Society of Sports Nutrition , 2011, DOI: 10.1186/1550-2783-8-21
Abstract: Carbohydrate availability is one of the crucial factors for performance in endurance [1] and high-intensity intermittent exercise [2]. It has been well-documented that carbohydrate supplementation before a single-bout of endurance [3] and high-intensity intermittent exercise [4] could improve the performance. In real circumstances, many athletes undergo more than 1 training session per day. In addition, many competitions require athletes to participate in multiple events in a single day. Therefore, adequate nutritional strategies during the short-term post-exercise recovery period may be critical for the performance in subsequent exercise. Several studies have shown that ingestion of protein with carbohydrate after exercise increases muscle glycogen resynthesis rate, compared to the same amount of carbohydrate [5,6]. The increased muscle glycogen recovery may lead to the improved performance during subsequent endurance exercise [7].Muscle glycogen resynthesis after exercise consists of two phases. The initial insulin-independent phase that lasts approximately 1 hour has a higher resynthesis rate. It is followed by an insulin-dependent phase with a lower rate that lasts several hours [8]. Previous studies have suggested that branched-chain amino acids (BCAA) and arginine may help improve both phases. Studies in rats have shown that BCAA could stimulate insulin-independent glucose uptake in skeletal muscle by increasing the translocation of glucose transporter (GLUT)-4 and GLUT-1 to the sarcolemma [9]. Leucine also activated glycogen synthetase via activation of mammalian target of rapamycin (mTOR) signals in isolated muscles [10]. Isoleucine increased insulin-independent glucose uptake and glycogen synthesis in C2C12 myotubes [11]. In addition, nitric oxide (NO), a product of arginine, could increase the insulin-independent expression and translocation of GLUT-4 in rat skeletal muscles [12]. The vasodilation effect of arginine could increase blood flow and substrate

Abstract: A total of 165 individuals practicing Waitankung were matched by age and sex with 660 general individuals for comparison. Information about health-related quality of life, measured by the SF-36, and other basic and health conditions was obtained from the questionnaires. This study used the linear mixed-effect regression model to examine the association between health-related quality of life and the practice of Waitankung.Compared with either sedentary individuals or individuals practicing other types of exercise, the Waitankung group scored higher for eight and five out of ten SF-36 components, respectively. The Waitankung group scored better in general health, vitality, and physical component summary compared to individuals participating in other types of exercise, even when considering the energy expended by exercise.The results suggest that Waitankung exercising is significantly associated with health-related quality of life. Waitankung may serve as an exercise choice for middle-aged and older people to improve overall quality of life.Among the tools for promoting health, physical activity plays an essential role because of its beneficial effect on health, including reduced risk of mortality and developing cancer, type II diabetes, and high blood pressure in the general population, and geriatric conditions in the older population [1]. In Chinese society, Tai Chi Chuan and Qigong are two popular physical activities, mainly because of their potential physical and mental benefits and gentle movements suitable for middle-aged and old people. Several studies have found that Tai Chi Chuan and Qigong provide health benefits similar to other physical activities [2,3]. For example, in a recent review of randomized control trials for Tai Chi Chuan and Qigong, both provide similar health benefits of bone density, cardiopulmonary effects, physical function, falls, quality of life, self-efficacy, reported health outcomes, psychological symptoms, and immune function [3].In Tai

Molecules , 2012, DOI: 10.3390/molecules17089774
Abstract: Endoglucanase B (EGLB) derived from Aspergillus niger BCRC31494 has been used in the food fermentation industry because of its thermal and alkaline tolerance. It was cloned and expressed in Pichia pastoris. According to sequence analysis, the gene open reading frame comprises 1,217 bp with five introns (GenBank GQ292753). According to sequence and protein domain analyses, EGLB was assigned to glycosyl hydrolase family 5 of the cellulase superfamily. Several binding sites were found in the promoter region. The purified recombinant enzyme was induced by 0.5% methanol, and it exhibited optimal activity at 70 °C and pH 4. EGLB was stable for 3 h at temperatures below 60 °C, with more than 90% of its activity remaining. The enzyme was specific for substrates with β-1,3 and β-1,4 linkages. In Lineweaver-Burk plot analysis, the Km and Vmax values of EGLB for β-D-glucan were 134 mg/mL and 4.68 U/min/mg, respectively. The enzyme activity was increased by 1.86-fold by Co2+ and by 2-fold by Triton X-100 and Tween 80. These favorable properties make EGLB a potential candidate for use in laundry and textile industrial applications.

Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.53047
Abstract:

In this paper, we study multiple shot noise process and its integral. We analyse these two processes systematically for their theoretical distributions, based on the piecewise deterministic Markov process theory developed by Davis [1] and the martingale methodology used by Dassios and Jang [2]. The analytic expressions of the Laplace transforms of these two processes are presented. We also obtain the multivariate probability generating function for the number of jumps, for which we use a multivariate Cox process. To derive these, we assume that the Cox processes jumps, intensity jumps and primary event jumps are independent of each other. Using the Laplace transform of the integral of multiple shot noise process, we obtain the tail of multivariate distributions of the first jump times of the Cox processes, i.e. the multivariate survival functions. Their numerical calculations and other relevant joint distributions numerical values are also presented.

Design and Control of a Ferromagnetic Coded Micro-Carrier Biochip Sensor for Multiplex Detection of Antibodies

Sensors , 2011, DOI: 10.3390/s110807851
Abstract: This paper describes a method for producing a novel type of ferromagnetic coded micro-carrier. The ferromagnetic coded micro-carriers are about 200 μm in length, 200 μm in width and 50 μm in thickness, and contain eight code elements with two distinguishable codes (hollow and solid), allowing for 28 unique codes. The code shapes include rectangle, circle, etc. Differently shaped coded micro-carriers could carry different antigens for detection of its complementary antibody. These many shapes of coded micro-carriers would be used simultaneously allowing us to make multiple detections for different antibodies at the same time. A molding process is applied for fabrication of the ferromagnetically coded micro-carriers where Fe material (Fe powder mixed with binder) is shaped in many tiny molds to produce the coded shapes used for identification of the bio-molecules. Magnetic force is used to control the movement and location of the ferromagnetic coded micro-carriers to prevent the loss during the hybridization process. The results of image process and analysis system testing are satisfactory. The results of our micro-carrier detection system for two sets of R and B color analysis are proportional to those obtained from ELISA antibody detection.

Abstract: The micrographs of epoxy resin on single carbon fiber at room temperature and the temperature dependent contact angle on single carbon fiber were investigated using field environmental scanning electron microscope (FESEM).The results showed that the contact angle decreases significantly with increasing temperature.The advantage of this experimental approach was that can directly reflected the wettability of epoxy resin to fiber.But the experimental process was complicated,and there were many influence factors.The reason is that the wettability of epoxy resin on parallel sheet can be improved at higher temperatures.The spreading procedures for the epoxy resin droplet on carbon fiber cluster were observed by means of drop shape analysis system (DSA) in parallel and perpendicular directions of the aligned fibers.It was found that the temperature dependent contact angles were quite distinct from the different observed directions.Moreover,the contact angles observed perpendicular to the direction of fibers are consistent with the results on the single carbon fiber,which indicates that the wetting behavior of epoxy resin to the fiber in the direction parallel to the fiber cluster can truly represent the wettability.Then,the complicated method about single fiber of using FESEM to understand the wettability of epoxy resin to fiber could be replaced by using DSA.It should save much time and energy for the practical industry.

Thermal Science , 2011, DOI: tsci11s1053w
Abstract: In this paper, Taguchi method is applied to optimize ultrasound thermal process for extracting caffeine and flavor from coffee. The use of ultrasound can abridge experiments in cost, energy loss and time; the different operating conditions for extraction experiments are executed and the results are also compared. The results show that the best design factors for caffeine are 95℃ of extraction temperature, 28 kHz of operating frequency and 30 s of extraction time. The proposed optimized extraction method is efficient and energy-saving compared with the general process for making coffee.

Thermal Science , 2011, DOI: tsci11s1069w
Abstract: In this research, our focus is the use of ultrasound thermal process to extract flavor and caffeine from coffee. The different operating conditions for extraction experiments are executed and the results are also compared. The results show that coffee flavor is not enhanced with the increase of temperature because the volatile degree of coffee flavor components is quick and easy to be reached at high temperatures. From the experimental results, it can be found that using low vibration frequency is better than using high vibration frequency. Also, caffeine will be reached into the saturated state at the 15th second of the extracting time and the quantity of caffeine augments with the increase of temperature.
Solvent-Induced Phase-Inversion and Electrical Actuation of Dielectric Copolymer Films  [PDF]
Yeonju Jang, Toshihiro Hirai
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.23023
Abstract: Block copolymers posses inherently the ability of form a variety of phase-separated microdomain structures. The lengths of block segments and the selectivity of the solvent are primary factors affecting the resultant morphology. This paper investigated the effect of casting solvents on the morphologies and electrical actuation of poly(methyl methacrylate)-poly(n-butyl acrylate)-poly(methyl methacrylate) (PMMA-PnBA-PMMA) triblock copolymer films comprising PMMA hard segment and PnBA soft segment. Transmission electron microscopy and confocal laser scanning microscopy observation revealed that PMMA and PnBA segments were assembled into various micro- and nano-sized phase structures where either of them formed continuous phase. This implies that continous phase could be inversed by used casting solvents. Solvent-dependent phase morphologies had a significant effect on the electrical actuation results. Increase of the PnBA contents and the continuous phases of PnBA soft segments improved both of electrical actuation and dielectric constant, indicating that solvent-induced phase separation modulates the electrical actuation of dielectric films. The significance of the role of solvent selectivity and the major continuous phase of the polymer in defining the morphology and electrical actuation of the self-assembled block copolymer structure are discussed.
