“…ADSCs in combination with atelocollagen honeycombshaped scaffold (ACHMS scaffold; Masuoka et al, 2006) or fibrin glue scaffolds (Dragoo et al, 2007) have been reported for repairing cartilage defects in rabbit joints. ADSC-loaded cartilage ECM scaffolds have been further evaluated in vitro by other groups and it has been shown that human ADSCs attached to porous scaffolds derived from adult porcine articular cartilage and retained similar morphology chondrocytes (Cheng et al, 2009). The above scaffolds also demonstrate strong support for ADSCs in terms of chondrogenic differentiation, even without the addition of exogenous growth factors.…”

We have previously reported a natural, human cartilage ECM (extracellular matrix)-derived three-dimensional (3D) porous acellular scaffold for in vivo cartilage tissue engineering in nude mice. However, the in vivo repair effects of this scaffold are still unknown. The aim of this study was to further explore the feasibility of application of cell-loaded scaffolds, using autologous adipose-derived stem cells (ADSCs), for cartilage defect repair in rabbits. A defect 4 mm in diameter was created on the patellar groove of the femur in both knees, and was repaired with the chondrogenically induced ADSC-scaffold constructs (group A) or the scaffold alone (group B); defects without treatment were used as controls (group C). The results showed that in group A all defects were fully filled with repair tissue and at 6 months post-surgery most of the repair site was filled with hyaline cartilage. In contrast, in group B all defects were partially filled with repair tissue, but only half of the repair tissue was hyaline cartilage. Defects were only filled with fibrotic tissue in group C. Indeed, histological grading score analysis revealed that an average score in group A was higher than in groups B and C. GAG and type II collagen content and biomechanical property detection showed that the group A levels approached those of normal cartilage. In conclusion, ADSC-loaded cartilage ECM scaffolds induced cartilage repair tissue comparable to native cartilage in terms of mechanical properties and biochemical components.

“…[48,49] Therefore, once again, his questions and doubts were replied. [50] In our opinion, if the researchers on both sides can focus on some new specific application cases, it may be helpful to make the discussion and argument clear. For instance, in the present paper, our examples show that the entransy theory is different from the entropy generation minimization.…”

“…These doubts and negative comments have all been replied and discussed, and it has been shown that the entransy theory has its physical basis and advantages in applications. [46][47][48][49][50][51][52] However, the applicability of entransy theory to the Carnot heat engine with irreversible processes still needs further investigations.…”

In this paper, an endoreversible Carnot heat engine with irreversible heat transfer processes is analyzed based on generalized heat transfer law. The applicability of the entropy generation minimization, exergy analyses method, and entransy theory to the analyses is discussed. Three numerical cases are presented. It is shown that the results obtained from the entransy theory are different from those from the entropy generation minimization, which is equivalent to the exergy analyses method. For the first case in which the application preconditions of the entropy generation minimization and entransy loss maximization are satisfied, both smaller entropy generation rate and larger entransy loss rate lead to larger output power. For the second and third cases in which the preconditions are not satisfied, the entropy generation minimization does not lead to the maximum output power, while larger entransy loss rate still leads to larger output power in the third case. For the discussed cases, the concept of entransy dissipation is not applicable for the analyses of output power. The problems in the negative comments on the entransy theory are pointed out and discussed. The related researchers are advised to focus on some new specific application cases to show if the entransy theory is the same as some other theories.
