Recent development of three-dimensional (3D) high definition (HD) ultrasound has resulted in remarkable progress in visualization of early embryos and fetuses in sonoembryology. The new technology of HDlive assesses both structural and functional developments in the first trimester with greater reliably than two-dimensional (2D) ultrasound. The ability to visualize not only fetal face, hands, fingers, feet, and toes, but also amniotic membranes, is better with volumetric ultrasound than 2D ultrasound. In this article, detailed and comprehensive structures of normal and abnormal fetuses depicted by 3D HDlive are presented, including various faces of Down's syndrome and holoprosencephaly, as well as low-set ear and finger/toe abnormalities from the first trimester. Three-dimensional HDlive further "humanizes" the fetus, enables detailed observation of the fetal face in the first trimester as shown in this article, and reveals that a small fetus is not more a fetus but a "person" from the first trimester. There has been an immense acceleration in understanding of early human development. The anatomy and physiology of embryonic development is a field where medicine exerts greatest impact on early pregnancy at present, and it opens fascinating aspects of embryonic differentiation. Clinical assessment of those stages of growth relies heavily on 3D/four-dimensional (4D) HDlive, one of the most promising forms of noninvasive diagnostics and embryological phenomena, once matters for textbooks are now routinely recorded with outstanding clarity. New advances deserve the adjective "breathtaking", including 4D parallel study of the structural and functional early human development.

The purpose of this study was to compare sweating function in sprinters who have trained for several years with untrained subjects and trained endurance runners. Two separate experiments were conducted. Nine sprinters, eight untrained men, and nine distance runners (VO2max 50.9 ± 1.4, 38.2 ± 1.8, and 59.1 ± 1.2 mL/kg/min, respectively; P < 0.05) were passively heated for 50 min (Experiment 1), and ten sprinters, 11 untrained men and nine distance runners (similar VO2max levels compared with Experiment 1 in each group) had their sweat gland capacity assessed based on acetylcholine-induced sweating rate (SR) (Experiment 2). The slope of the mean non-glabrous SR plotted against change in mean body temperature during passive heating did not differ significantly between sprinters and untrained men (1.21 ± 0.10 and 0.97 ± 0.12 mg cm-2/min/ C, respectively); in contrast, compared with untrained men, distance runners exhibited a significantly greater slope (1.42 ± 0.11 mg cm-2/min/ C, P < 0.05). The mean body temperature threshold for SR was not significantly different among the groups. Acetylcholine-induced SR did not differ significantly between sprinters and untrained men, whereas distance runners showed a significantly higher induced SR compared with untrained men. The sweating function was not improved in sprinters who have trained 2-3 h/day, 5 days/week, for at least 3 years compared with untrained men, although the VO2max was markedly greater in sprinters. Thus, there is a case that daily training was not sufficient to improve sweating function in sprinters relative to those in distance runners. © 2013 Springer-Verlag Berlin Heidelberg.

This review focuses on the characteristics of heat-loss responses during exercise with respect to non-thermal factors. In addition, the effects of physical training on non-thermal heat-loss responses are discussed. When a subject is already sweating the sweating rate increases at the onset of dynamic exercise without changes in core temperature, while cutaneous vascular conductance (skin blood flow) is temporarily decreased. Although exercise per se does not affect the threshold for the onset of sweating, it is possible that an increase in exercise intensity induces a higher sensitivity of the sweating response. Exercise increases the threshold for cutaneous vasodilation, and at higher exercise intensities, the sensitivity of the skin-blood-flow response decreases. Facilitation of the sweating response with increased exercise intensity may be due to central command, peripheral reflexes in the exercising muscle, and mental stimuli, whereas the attenuation of skin-blood-flow responses with decreased cutaneous vasodilation is related to many non-thermal factors. Most non-thermal factors have negative effects on magnitude of cutaneous vasodilation; however, several of these factors have positive effects on the sweating response. Moreover, thermal and non-thermal factors interact in controlling heat-loss responses, with non-thermal factors having a greater impact until core temperature elevations become significant, after which core temperature primarily would control heat loss. Finally, as with thermally induced sweating responses, physical training seems to also affect sweating responses governed by non-thermal factors. © 2010 Springer-Verlag.

We assessed sex differences in the sweat gland response to changes in exercise intensity with respect to subjects' physical training status. In total, 37 subjects participated (10 trained and 10 untrained females, and 8 trained and 9 untrained males). Each subject cycled continuously at 35, 50 and 65% of their maximal O 2 uptake () for 60 min at an ambient temperature of 30°C and a relative humidity of 45%. The mean local sweating rate (SR) on the forehead, chest, back, forearm and thigh was significantly greater in the trained subjects than in the untrained subjects of both sexes. The degree of the increase in SR with physical training was greater in males than in females at higher levels of exercise intensity. This increase in SR depended primarily on an increase in the sweat output per gland (SGO) in both sexes. However, control of the SR increase with increasing exercise intensity was altered by training in females, i.e. the increase in SR from exercise at 50 to 65% depended only on an increase in SGO in trained females and males and untrained males, but it depended on increases in activated sweat glands and the SGO in untrained females. It was concluded that training improved the sweating response, and a sex difference was observed in the degree of improvement in the sweating response due to physical training. This sex difference became more pronounced with increasing exercise intensity. A sex difference was observed in the control of sweating rate to an increase in exercise intensity, i.e. the maximal activated sweat gland responses of untrained females required a higher body temperature or work intensity than the other groups. © 2010 The Physiological Society.

The present study examined sex differences in the sweat gland response to acetylcholine (ACh) in physically trained and untrained male and female subjects. Sweating responses were induced on the forearm and thigh in resting subjects by ACh iontophoresis using a 10% solution at 2 mA for 5 min at 26°C and 50% relative humidity. The ACh-induced sweating rate (SR) on the forearm and thigh was greater in physically trained male (P < 0.001 for the forearm and thigh, respectively) and female (P = 0.08 for the forearm, P < 0.001 for the thigh) subjects than in untrained subjects of both sexes. The SR was also significantly greater in physically trained males compared to females at both sites (P < 0.001) and in untrained males compared to females on the thigh (P < 0.02) only, although the degree of difference was greater in trained subjects than in untrained subjects. These sex differences can be attributed to the difference in sweat output per gland rather than the number of activated sweat glands. We conclude that physical training enhances the ACh-induced SR in both sexes but that the degree of enhancement is greater in male than in female subjects. The effects of physical training and sex on the SR may be due to changes in peripheral sensitivity to ACh and/or sweat gland size.

Since China implemented the economic reform and opening up strategy in 1978, Chinese economy has been booming. At the same time, foreign enterprises' entrance into China also boosts the development of Chinese economy. After the Second World War, Japanese economy began to develop very fast, occupying an important place in the mold manufacturing industry. Since the second half of 1980s, Japanese mold manufacturing industry has reached the level of advanced countries, which makes a big influence on Japan's industrial development. However, Japanese mold manufacturing industry is greatly affected by the recession of Japanese economy, which results in such consequences as scale shrinking and practitioner decreasing. After 30 years of the reform and opening up, Chinese mold industry has achieved remarkable development mainly due to the introduction of advanced equipment and processing method from foreign countries. By digestion and absorption of these technologies, China's technical level keeps improving. After the financial crisis, as the export decreases, price of materials rises, labor cost increases and so on, Chinese mold manufacturing enterprises are faced with diversified subjects. In the world economic crisis, the age for Sino-Japan mold enterprises to think their survival carefully is coming. These enterprises must face this reality in the future. It is necessary to take initiative measures quickly after balancing all matters.

Chinese market is indispensable for the world's automobile enterprises, and all enterprises have strengthened the investment in Chinese market. Therefore, in order to expand more market shares in China, all automobile companies and independent automotive enterprises have implemented a series of management strategies, and, as a result, made the competition in China more intense. However, Chinese automobile enterprises have not been known to the world. Therefore, this paper selected the independent automobile company Chery as an example, based on the analysis of Chery automobile company, using SWOT and five forces model (5F) analysis to analyze it. Finally, we would like to put forward four solutions to solve the current problems. Through this paper, we hope to make contribution to the development of Chinese automobile enterprises in the future. © 2012 IEEE.

Transportation Problem (TP) is a well-known basic network model that can be defined as a problem to minimize the total delivery cost. But when we apply to real world, the TP model should be extended to satisfy other additional constraints. In addition, traditional TP model does not treat the concept of opportunity loss and customer demand is always satisfied. In the real world, there are many cases where customer demand is not satisfied, and opportunity loss occurs. In this paper, we formulate a multi-period transportation problem with opportunity loss and inventory cost. To solve the problem, we designed Differential Evolution (DE) with random key-based representation as efficient solution method for proposal TP model. © Springer International Publishing Switzerland 2016.
