in this study, based on a biomimetic approach, novel 3d biodegradable porous hybrid scaffolds consisting of chitosan, gelatin, and tricalcium phosphate were developed for bone and cartilage tissue engineering. macroporous chitosan/ gelatin/β-tcp scaffolds were prepared through the process of freeze-gelation/solid-liquid phase separation. the results showed that the prepared scaffolds are highly...

This research aims to study the effect of interference with tripartite motif-containing protein 26 expression on proliferation intracranial glioma cells. randomly selected 60 cases specimens and brain tissue 10 trauma patients as a normal control group. First, cell culture is performed observe growth status Subsequently, small interfering ribonucleic acid technique was used interfere lines A172...

Neurofibroma is a tumor composed of a complex proliferation of neuromesenchymal tissue (Schwann cells, perineural cells, fibroblast, and mast cells). We report a 45-year-old female who had a slow growing, large, soft, pedunculated mass on her left lateral neck. A skin biopsy confirmed the diagnosis of neurofibroma.

The liver is the only organ that can regenerate and regain its original tissue-to-body weight ratio within a short period of time after tissue loss. Insufficient regeneration in patients partial hepatectomy or transplantation with grafts often leads to post-hepatectomy failure small-for-size syndrome, respectively. Enhancing injury might improve outcomes increase patient survival. Liver compris...

Background: The human endometrium undergoes cyclical changes including proliferation, differentiation, tissue breakdown and shedding (menstruation) throughout a woman’s reproductive life. The postovulatory rise in ovarian progestrone induces profound remodeling in chromatin structure of cells, and consequently differentiation of estradiol-primed endometrium. This change is crucial for embryo im...

objective: by date investigations have indicated the presence of stem cells within the pulp tissue of both temporary and permanent human teeth. in the present study, these stem cells were compared in terms of their growth kinetics and culture requirements. materials and methods: stem cells within the pulp of the human third molar (permanent tooth) and the deciduous incisor (temporary tooth) wer...
