Introduction: To attach the fetus to the endometrial epithelium, the endometrium should be affected and allowed by the steroid hormones secreted from the ovary. Thus, the endometrium is then subject to several structural and biochemical changes. Implantation involves the embedment, adhesion and invasion steps that specific receptors are engaged in that. The role of membrane receptors in uterine...

Forward osmosis (FO) requires a specific membrane structure for applications like juice concentration. The phase inversion method was used to make cellulose acetate (CA) FO membranes. solvents were acetone and 1,4-dioxane. Additives included polyvinylpyrrolidone (PVP), methanol, maleic acid in the preparation of CA membrane, which it easier improve membrane's permeability. performance fabricate...

This paper presents the results of mechanical strength of wet and dry zirconia/ Nafion® nano-composite membrane. The tensile tests were conducted to determine elastic modulus and stiffness of dry and wet pristine Nafion® membrane and modified Nafion® membrane. The composite membranes were prepared by recast method of different synthesized zirconium oxide with the zirconia content of 10% by weig...

MFI zeolite membranes were prepared on porous α-alumina substrates, using secondary growth of nano-seeded layers. The resulting membranes were characterized by means of Scanning Electron Microscopy (SEM), X-Ray Diffractometry (XRD), and pervaporation performance tests for separation of Benzene, Toluene and Xylene (BTX) mixture from contaminated water. The morphology, thickness, homogeneity,...

We have used an ultrasensitive force probe and optical interferometry to examine the thickness compressibility of the red cell membrane in situ. Pushed into the centers of washed-white red cell ghosts lying on a coverglass, the height of the microsphere-probe tip relative to its closest approach on the adjacent glass surface revealed the apparent material thickness, which began at approximately...

In the present study, the effect of alumina on the pore structure and hydrothermal stability of nanostructured silica was investigated. SiO2 and SiO2-15wt%Al2O3 membranes were prepared by dip coating on mesoporous γ-Al2O3 coated macroporous α-alumina support. The particle sizes of sol were increased by adding of alumina to silica...

This paper is devoted to the application of new low cost ceramic ultrafi ltration membranes material coming from the Tunisian ores (mud) which is usually considered as disastrous for the environment. A ceramic tubular support previously elaborated from mud was coated in the lumen side by slip casting method. After sintering at 650°C, the coated membrane shows homogeneou...

The present study was designed to evaluate the effects of platelet growth factors and periosteal mesenchymal stem cells on bone healing process, radiographically. Forty male White New Zealand rabbits in five equal groups were used in this study. A 2 mm full thickness bone defect was made in left radial bone of each animal. In group A (control) the defect was left with no medical intervention. I...
