Adiponectin (Ad), a 30 kDa molecule, is an anti-diabetic adipokine; although derived from adipose tissue, it performs numerous activities in various other tissues. It binds to its own receptors, namely adiponectin receptor 1(AdipoR1), adiponectin receptor 2 (AdipoR2), and T-cadherin (CDH13). Ad plays several roles, especially as a regulator. It modulates lipid and glucose metabolism and promotes insulin sensitivity. This demonstrates that Ad has a robust correlation with fat metabolism. Furthermore, although Ad is not in direct contact with other tissues, including the skin, it can be delivered to them by diffusion or secretion via the endocrine system. Recently it has been reported that Ad can impact skin cell biology, underscoring its potential as a therapeutic biomarker of skin diseases. In the present review, we have discussed the association between skin cell biology and Ad. To elaborate further, we described the involvement of Ad in the biology of various types of cells in the skin, such as keratinocytes, fibroblasts, melanocytes, and immune cells. Additionally, we postulated that Ad could be employed as a therapeutic target to maintain skin homeostasis.

Although Wangfu's Tian-Ren relations theory could not be free from the influence of the religious understanding of the Yinyangwuxing theory, which was prevalent in the times of two Hans, due to the limitations of the times, it refers to human status and capabilities here and there of the "Qianfulun" and traces of attempts to enhance humans' ability to preside and attempts to dilute the powers of Tian(heaven) and God can be found. In addition, the fact that the theory shifted the focus of the administration and politics of the state from Tian(heaven) to the people can be also said to be highly worthwhile. Of course, when seen from philosophical, political, social, and economic perspectives, Wangfu's primary concern can be said to have been the stabilization of people's livelihood. The influence and contribution of Wangfu's ?Qianfulun? as such on the aspects of political and philosophical thoughts in the society at the time can be said to be comparable to those of Wangchong. Although there are the limitations of the situations of the times faced by Wangfu that made him unable to surpass the standardized paradigm of the Tian-Ren response theory, when seen from other perspectives, the fact that he severely criticized the confused social conditions at that time unlike other intellectuals in the confused situations at the end of the East Han Dynasty period can be said to be worth affirmation. The fact that Wangfu, who tried to work on the basis, the stabilization of the people's livelihood, concentrated most of his energy on overcoming the situation of national internal and external troubles such as breaking down the bad customs of operating the national administration by religious notions such as natural calamity or superstition instead of trying to solve the problems of the times from the academic and ideological aspects as with Wangchong can be also said to be valuable in itself. In addition, Wangfu naturally became to take the lead in breaking down deeply superstitious notions such as the Yinyangwuxing theory and the Chanwei theory while he was conducting studies on how practical problems could be overcome facing the situations in the turbulent period.

In this paper, we propose a new algorithm to modify the standard Mann' process to have strong convergence for $k$-strictly pseudo-contractive non-self mapping in Hilbert spaces.

Taxicab plane geometry and Cinese-Checker plane geometry are non-Euclidean and more practical notion than Euclidean geometry in the real world. The ${\alpha}$-distance is a generalization of the Taxicab distance and Chinese-Checker distance. It was first introduced by Songlin Tian in 2005, and generalized to n-dimensional space by Ozcan Gelisgen in 2006. In this paper, we studied the isoperimetric inequality in ${\alpha}$-plane.

In this paper, merits of both fuzzy and PID controllers are combined. The combined controller is designed such that the tuning of the PID controller is achieved by the basic fuzzy controller via its rule base. The proposed scheme avoids the tuning of PID parameters which is always a time consuming task, difficult to carry out and often poorly done. Computer simulations are made to demonstrate the satisfactory tracking performance of the combined fuzzy-PID controller.

An identification key to twenty-nine species of Porina known from Vietnam is provided. In addition, new records of Porina eminentior, P. meridionalis and P. nuculastrum are described from the protected rain forests in southern Vietnam. A detailed taxonomic account of the newly reported species is provided and supported by its ecology, distribution, and illustrations.
