Platelet-rich plasma has been used to treat articular cartilage defects, with the expectations of anabolic and anti-inflammatory effects. However, its role on cellular chondrogenic or fibrogenic commitment is still a controversy. Herein, the role of platelet-rich plasma releasate, the product obtained following platelet-rich plasma activation, on cellular commitment toward the chondrogenic line...

We examined the proliferative behaviour in tertiary culture cells of human skin fibroblasts (HSF) as well as cells of the rat 3Y1 diploid fibroblast line placed on a plastic substratum in a nutrient-rich medium containing high concentrations of platelet-poor plasma (PPP). Autochthonous human PPP was used for the HSF cells and heat-treated (at 56 degrees C for 30 min) bovine PPP was used for the...

The Frizzled (Fz) receptors contain seven transmembrane helices and an amino-terminal cysteine-rich domain (CRD) that is sufficient and necessary for binding of the ligands, the Wnts. Recent genetic experiments have suggested, however, that the CRD is dispensable for signaling. We engineered fz CRD mutant transgenes and tested them for Wg signaling activity. None of the mutants was functional i...

Culture is the most basic cause of a person’s wants and behavior. Country, like China, who has such a long history, has rich culture background. So it is very critical for international cooperates who want to do business in China to know about Chinese culture and how it works to buyers’ behavior. Starting from Chinese culture in Marketing context, this paper discusses how culture influence buye...

  Objective(s): Platelet-rich plasma (PRP) has recently emerged as a promising strategy in regenerative medicine due to its multiple endogenous growth factors. Little is known about the role of PRP as a promoter in chondrogenesis of human adipose derived stem cells (hADSCs). The aim of this study was to determine whether PRP may be considered as a natural and easy achievable source o...

Sodium alginate, mannuronic acid-rich and guluronic acid-rich fractions were prepared from "Mekabu" (sporophyll of Undaria pinnatifida). The production of short-chain fatty acids such as acetic, propionic and n-butyric acids from these fractions in mini-scale batch culture using pig cecal bacteria was studied, and the gas released from the culture was monitored. The volume of released gas corre...

The relationship between language and culture has become a rich source of inquiry in the context of English language teaching. Learning materials can depict cultural content in different cultural senses, namely aesthetic, sociological, semantic, and pragmatic. The present study aimed to investigate the way cultural aspects are represented in the reading and dialog sections of global (American E...

Uyghur food culture has a long history. It is rich in resources, with the strong characteristics of being "green" and healthy, and having high nutritional value. We analyze the development and current status of Uyghur food culture, and explore the value of developing this food culture's resources. Traditional Uyghur food culture formed with influences from many ethnic groups, and has evolved in...

Matrix vesicles (MV) can be readily isolated from culture media of chicken growth plate hypertrophic chondrocytes grown in primary culture. The chondrocytes maintain normal morphology and synthesize type I1 collagen throughout the culture period. The culturederived MV are morphologically indistinguishable from MV seen in situ and are rich in alkaline phosphatase. Formation of alkaline phosphata...
