In this paper a decomposition technique suitable for any grey-scale soft morphological structuring element is presented. A hardware structure implementing this technique is also presented.

Despite recent advances in drug delivery systems and tissue engineering, several challenges still need to be overcome for these new technologies reach patients. The number of cancer cases is increasing yearly, the future projection frightening. Another major health concern rise antibiotic-resistant bacteria. uncontrolled excessive use antibiotics has allowed bacteria undergo mutation processes,...

Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite  (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...

background: the aim of this study was to fabricate the poly caprolactone (pcl) aligned nanofiber scaffold and to evaluate the survival, adhesion, proliferation, and differentiation of rat hair follicle stem cells (hfsc) in the graft material using electrospun pcl nanofiber scaffold for tissue engineering applications. methods: the bulge region of rat whisker was isolated and cultured in dmem: n...

• Compose personalized documents for the reader. For example, once could have a text base on statistical methods, where each topic is treated at several levels (such as for readers who know calculus and those who do not) and where each method has examples from several domains. Given a reader’s background, subject domain, and learning goal, the system would then sequence of topics that build on ...

In this study, mechanical properties and apatite formation ability of synthesized fluorapatite-hardystonite (FA-HT) nanocomposite scaffolds were investigated. Hardystonite (HT; 5 and 10 wt.%) as a reinforcement phase was incorporated into the FA scaffold. FA was mixed with HT for 4 h under argon gas at 220 °C. A space holder method was used for fabricating porous FA-HT scaffolds. Sodium chlorid...

The decomposition of a binary morphological structuring element is a well-known problem that has often been addresses in the literature. This work present a new approach based on an Evolution Program: using an iterative stochastic technique,it allows to determinethe optimal decomposition of an arbitrarily shaped binary morphological structuring element into the shortest chain of elementary fact...

Two-photon polymerization is an appealing technique for producing microscale devices due to its flexibility in producing structures with a wide range of geometries as well as its compatibility with materials suitable for biomedical applications. The greatest limiting factor in widespread use of two-photon polymerization is the slow fabrication times associated with line-by-line, high-resolution...

cartilage is an avascular, aneural, and alymphatic connective tissue with a limited capacity caused by low mitotic activity of its resident cells, chondrocytes. natural repair of full thickness cartilage defects usually leads to the formation of fibrocartilage with lower function and mechanical force compared with the original hyaline cartilage and further deterioration can occur. tissue engine...

background: engineering new bone tissue with cells and a synthetic extracellular matrix represents a new approach for the regeneration of mineralized tissues compared with the transplantation of bone (autografts or allografts). methods: in this study, to mimic the mineral and organic component of natural bone, hydroxapatite (ha) and gelatin (gel) composite scaffolds were prepared. the raw mater...
