Increasing attention is being placed on the use of adult stem cells due to their potential therapeutic applications for unmet medical needs. Among all adult stem cell types, umbilical cord mesenchymal stem cells (UCMSCs) can be collected easily and does not harm newborns and the mothers. The excellent pluripotency and proliferation potential of UCMSCs has(More)
BACKGROUND Esophageal squamous cell carcinoma is one of the most common malignancies in the world. Studies have confirmed that there are many genes abnormally hypermethylated in esophageal squamous cell carcinoma. The objective is to detect methylation of the RASSF1A gene promoter and the expression of the DNA methyltransferase 1 (DNMT1) protein in(More)
UNLABELLED Human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) have higher proliferation potency and lower immune resistance than human bone marrow MSCs and can differentiate into various functional cells. Many regulatory factors, including keratinocyte growth factor (KGF), are involved in the development of skin and cutaneous appendages.(More)
Orientations and positions of a permanent magnet can be acquired via a three-axis magnetic sensor array system. Thus, the position and orientation of an object embedded with the permanent magnet can be tracked in real-time. This magnet tracking system can be adapted to medical and industrial applications. How to detect the weak magnetic signal and the(More)
The majority of studies on scar formation have mainly focused on the dermis and little is known of the involvement of the epidermis. Previous research has demonstrated that the scar tissue-derived keratinocytes are different from normal cells at both the genetic and cell biological levels; however, the mechanisms responsible for the fundamental(More)
Tissue morphogenesis depends on precise regulation and timely co-ordination of cell division and also on the control of the direction of cell division. Establishment of polarity division axis, correct alignment of the mitotic spindle, segregation of fate determinants equally or unequally between daughter cells, are essential for the realization of oriented(More)
In this paper, we develop an improved energy-efficient mobile agent (EMA) paradigm for information aggregation in wireless sensor networks (WSNs). In EMA, destination node in each agent hopping keeps an instance of the arrival mobile agent's processing code. The following mobile agent, if the same information aggregation algorithm is required, carries only(More)
