Hydrocolloids are long-chain biopolymers that can form viscous solutions or gels when dissolved in water. They employed as rheological modifiers various manufacturing processes finished products. Due to its unique gelation properties, animal gelatin is one of the most widely used hydrocolloids, finding applications several fields such food, pharmaceutical, and photographic. Nowadays, challenge ...

Two-dimensional cell patterns prepared on substrate surfaces by an electrochemical-based biolithography method have been transferred into fibrin gels prepared in situ. Line patterns of human umbilical vein endothelial cells (HUVECs) in the gel that was strained after the transfer formed a linear vessel-like structure within 8 days.

background: in this study, two-dimensional gel electrophoresis (2-de) method was applied to determine and compare the protein spots expressed in the two field isolates of leishmania major and recovered from the patients who were clinically sensitive and resistant to glucantime® treatment. methods: leishmania parasites were isolated from the cutaneous lesions of two cl infected patients in shira...

PURPOSE To establish a baseline protein fingerprint of cultured human corneal endothelial cells (HCEC), to determine whether the protein profiles exhibit age-related differences, and to identify proteins differentially expressed in HCEC cultured from young and older donors. METHODS Corneas were obtained from five young (<30 years old) and five older donors (>50 years old). HCEC were cultured,...

A project to systematically investigate respiratory supercomplexes in plant mitochondria was initiated. Mitochondrial fractions from Arabidopsis, potato (Solanum tuberosum), bean (Phaseolus vulgaris), and barley (Hordeum vulgare) were carefully treated with various concentrations of the nonionic detergents dodecylmaltoside, Triton X-100, or digitonin, and proteins were subsequently separated by...

Although integrins are known to mediate adhesive binding of cells to the extracellular matrix, their role in mediating cellular growth, morphology, and differentiation is less clear. To determine more directly the role of the alpha 2 beta 1 integrin, a collagen and laminin receptor, in mediating the collagen-dependent differentiation of mammary cells, we reduced expression of the integrin by th...

We describe a three-dimensional (3D) cell culture system using monodisperse peptide hydrogel beads. We utilized a self-assembling peptide hydrogel to provide cells in vivo-like microenvironment. We succeeded in encapsulating endothelial cells within the hydrogels by using a 3D microfluidic axisymmetric flow-focusing device (AFFD), and showed the encapsulated endothelial cells were viable and we...
