*Article* **Applications of the Sine Modified Lindley Distribution to Biomedical Data**

**Abstract:** In this paper, the applicability of the sine modified Lindley distribution, recently introduced in the statistical literature, is highlighted via the goodness-of-fit approach on biological data. In particular, it is shown to be beneficial in estimating and modeling the life periods of growth hormone guinea pigs given tubercle bacilli, growth hormone treatment for children, and the size of tumors in cancer patients. We anticipate that our model will be effective in modeling the survival times of diseases related to cancer. The R codes for the figures, as well as information on how the data are processed, are provided.

confluency and stimulated to synthesize ECM by culture medium supplemented ascorbic acid. Matrices are denuded of cells and cellular remnants are removed by using Triton X-100,

Then, ECM coated culture surfaces are tested by staining with PI to access DNA remnant (see Figure 9), with H&E and PAS in order to characterize component of ECM. The results suggest that fibroblast-derived three-dimensional matrix was determined to be free of cellular constituents and still remain attached to the culture surface. The conducted matrices were

(for example, induction of cell attachment, proliferation…) was reported to be well-preserved

In order to evaluate the quality of the ECM, the test of cell rapid attachment ability is per‐ formed. Cell proliferation on ECM is also assessed. Results showed that the cultured cells attached and proliferated on ECM coated surfaces faster than on ECM non-coated surfaces.

Inmodernsociety,manydiseaseshavebeenincreasinginhumanbecauseofpollution, accident, lifestyle... The mutilation in human body leads to expand the needs of replacing tissues/ organs. However, the available source of tissues/organs is limited. Creating artificial tissues/ organsforreplacingdamaged,dysfunctionaltissues/organsbecomesabigdisciplineonmaterial science. Naturally derived biomaterials have been studied and applied in clinical applications as artificial tissues/organs because they are capable of supporting cell proliferation, biodegrad‐ ability and remodeling tissues. Although the current results have not completely satisfy the clinical demand, the potential applications of naturally derived biomaterials are still highly considered, therefore, research on this field have now being taken place all over the world.
