Human dermal fibroblasts (FBs) express mesenchymal stem cell (MSC)-specific cell surface markers and differentiate into several cell types under appropriate conditions. Molecular mechanisms controlling the early stages of differentiation of dermal FBs and MSCs isolated from different sources have not been well studied. Here, we have analyzed the cell type-specific changes of adipose tissue-deri...

BACKGROUND Foreign bodies (Fbs) in the ear, nose, and throat (ENT) are common presentations in healthcare settings worldwide. AIM This study was carried out to review the modes of presentation, management, and outcome of inserted Fbs in our setting. SUBJECTS AND METHODS A 5-year retrospective study of cases of ENT Fbs managed at two referral hospitals in Abuja Nigeria. The analysis was done...

The complete model included Innovativeness as the strategic orientation of the firm, firm size, industry, and business strategy (See Figure 2). For a complete description of all the variables measured in this study the reader is referred to an earlier research brief. Results The anticipated relationships were supported by our analyses. Business strategy was not found to impact the relationship ...

Fetal bovine serum (FBS) has been reported to affect chondrocyte biosynthesis in monolayer culture. Insulin-Transferrin-Selenium (ITS) was investigated as a partial replacement for FBS during in vitro culture of rabbit articular chondrocytes in three-dimensional alginate scaffold. Chondrocyte-seeded alginate hydrogels were cultured in Dulbecco's modified Eagle's medium plus 10% FBS, 1% ITS plus...

A nonuniform filter bank (FB) is one whose channel decimation rates need not all be equal. While the theory and design of uniform FBs is a very well developed subject, there are several interesting open issues in the area of nonuniform FBs. Most nonuniform FB designs either result in approximate or near–perfect reconstruction, or involve cascading uniform FBs in tree structures. This leaves una...
