Scarring, which occurs in essentially all adult tissue, is characterized by the excessive production and remodeling of extracellular matrix by α-smooth muscle actin (SMA)-expressing myofibroblasts located within connective tissue. Excessive scarring can cause organ failure and death. Oral gingivae do not scar. Compared to dermal fibroblasts, gingival(More)
Unlike skin, oral gingival do not scar in response to tissue injury. Fibroblasts, the cell type responsible for connective tissue repair and scarring, are exposed to mechanical tension during normal and pathological conditions including wound healing and fibrogenesis. Understanding how human gingival fibroblasts respond to mechanical tension is likely to(More)
Unlike skin, oral gingiva do not scar in response to injury. The basis of this difference is likely to be revealed by comparing the responses of dermal and gingival fibroblasts to fibrogenic stimuli. Previously, we showed that, compared to dermal fibroblasts, gingival fibroblasts are less responsive to the potent pro-fibrotic cytokine TGFβ, due to a reduced(More)
To solve the dilemma introduced by rate-distortion optimization (RDO) in H.264 rate control, the linear model of MAD prediction is applied. However, this model suits image characteristics locally but in some cases it could be inefficient. If there is a low spatial correlation (i.e., the encoder is processing pictures with varying characteristics), the MAD(More)
Algal polyunsaturated fatty acids (PUFA), essential for somatic growth and reproduction of aquatic animals, are influenced by ambient environmental conditions, including light and nutrients. Few studies have addressed the extent to which changes in algal PUFA can influence stream herbivore PUFA profiles and the implications for stream food webs. We(More)
Due to the error concealment recommended by H.264 cannot reconstruct the loss image effectively, an efficient error concealment method is proposed in this paper. The proposed scheme adoptively selects a proper concealment candidate to conceal the artifact of a lost block. To determine the best concealment candidate, a trial process in which the concealment(More)
A performance weighted deploying and scheduling strategy for virtual machine on clouds (PWDSS) is introduced in this paper concerning users' requests of virtual resources and cloud load balancing. This approach follows three stages: first to use a monitor toolkits to collect the cloud performance data from the virtual machines and physical machines of(More)
