AIMS To examine the efficacy of using fibrin glue (FG) as an interpositioning layer in the repair of complicated vesioovaginal fistulae (VVFe) as compared to the classical repair using martius flaps (Ml'). METHODS The study was conducted in 3 African institutions. Forty female patients with complicated VVFs were randomized into 2 groups. Group A were repaired anatomically using FG as interpos...

Buckling analysis of a functionally graded (FG) nanobeam resting on two-parameter elastic foundation is presented based on third-order shear deformation beam theory (TOSDBT). The in-plane displacement of TOSDBT has parabolic variation through the beam thickness. Also, TOSDBT accounts for shear deformation effect and verifies stress-free boundary conditions on upper and lower faces of FG nanobea...

Imprinted genes have prominent effects on placentation; however, there is limited knowledge about the manner in which the genes controlled by two paternally methylated regions on chromosomes 7 and 12 contribute to placentation. In order to clarify the functions of these genes in mouse placentation, we examined transcription levels of the paternally methylated genes, tissue differentiation and d...

Intrinsically disordered Phe-Gly nucleoporins (FG Nups) within nuclear pore complexes exert multivalent interactions with transport receptors (Karyopherins (Kaps)) that orchestrate nucleocytoplasmic transport. Current FG-centric views reason that selective Kap translocation is promoted by alterations in the barrier-like FG Nup conformations. However, the strong binding of Kaps with the FG Nups ...

This study is focused on finite element analysis of a model comprising femur into which a femoral component of a total hip replacement was implanted. The considered prosthesis is fabricated from a functionally graded material (FGM) comprising a layer of a titanium alloy bonded to a layer of hydroxyapatite. The elastic modulus of the FGM was adjusted in the radial, longitudinal, and longitudinal...

objective: hypertrophic scar involves excessive amounts of collagen in dermal layer and may be painful. nowadays, we can’t be sure about effectiveness of procedure for hypertrophic scar management. the application of stem cells with natural scaffold has been the best option for treatment of burn wounds and skin defect, in recent decades. fibrin glue (fg) was among the first of the natural bioma...

The free transverse vibrations of two-dimensional functionally graded double Euler–Bernoulli beam system connected through a variable Winkler elastic layer are presented. Modulus elasticity and the density material beams assumed to vary along thickness length according power-law exponential functions, respectively. governing differential equations motion established by means Hamilton’s principl...

In the present paper, a novel unconstrained higher-order theory (UCHOT) is applied to analyse free vibration of cylindrical sandwich shells with nanocomposite face sheets reinforced graphene platelets. UCHOT considers shear and thickness deformations. It assumed that cylinder includes soft core which embedded between functionally graded platelets composites (FG-GPLRC). FG-GPLRC sheet consists s...

Many fungal species including pathogens exhibit filamentous growth (FG) as a means of foraging for nutrients. Genetic screens were performed to identify genes required for FG in the budding yeast Saccharomyces cerevisiae. Genes encoding proteins with established functions in transcriptional activation (MCM1, MATalpha2, PHD1, MSN2, SIR4, and HMS2), cell wall integrity (MPT5, WSC2, and MID2), and...

Abstract Cellular structures are a favorite selection for the design of lightweight components and energy absorption applications due to several advantages such as their customizable stiffness strength. In this investigation, functionally graded (FG) triply periodic minimal surfaces, Schoen-IWP (SIWP), Schwarz primitive (SPrim) cellular were fabricated by masked stereolithography (MSLA) techniq...
