NANOSCALE CHEMICAL AND MECHANICAL HETEROGENEITY OF HUMAN DENTIN CHARACTERIZED BY AFM-IR AND BIMODAL AFM

Human dentin, as an important calcified tissue in the body, plays significant roles in withstanding masticatory forces and has a complex hierarchical organization. Understanding the composition and ultrastructure of dentin is critical for elucidating mechanisms of biomineralization under healthy and[r]

Cancer-associated fibroblasts (CAFs) play an important role in breast cancer pathogenesis by paracrine regulation of breast cancer cell biology. Several in vitro and mouse models have characterized the role of cell contact and cytokine molecules mediating this relationship, although few reports have[r]

Solving this problem led to the fourth step—training the operators in the statistical techniques necessary to monitor and trend their own quality. In this way, the phrase “quality at the source” was coined. This step enabled the operator to know down to the individual part when it was out [r]

The next level of organization is the ecosystem. An ecosystem consists of different communities of organisms associated within a physically defined space. For example, a forest ecosystem consists of animal and plant communities in the soil, forest floor, and[r]

The rampant uses of chemical pesticides by developing countries not only pollute the soil, also problem to environment and human. The current scenario is pollution of soil contaminated with heavy metals(HMs). Contamination of soil bad impact on both yields and crop qualities leads to decrement of ag[r]

Human cancer cell lines are used in research to study the biology of cancer and to test cancer treatments. Recently there are already some large panels of several hundred human cancer cell lines which are characterized with genomic and pharmacological data.

Dilated cardiomyopathy (DCM) is the most common form of non-ischemic cardiomyopathy. It is characterized by ventricular chamber dilation, and myocyte hypertrophy.
