Androgenic alopecia affects hair follicles from frontal and vertex area. Hair inductive properties of DPCs are lost in bi-dimentional (2D) culture. In a recent study three dimentional (3D) structure cultured was able to recapitulate 22% molecular signature the intact dermal papilla The aim this compare gene profile expression immortalised balding (B-DPCs) non-balding (NB-DPCs) 3 different cultu...
HARTFEX is a novel system that employs several tiers of HMMs recognisers that work in parallel to extract multi-dimensions of articulatory features. The features segments on the different tiers overlap to account for the co-articulation phenomena. The overlap and precedence relation among features are applied to a phonological parser for further processing. HARTFEX system is built on a modified...
In a recent paper, M.A. Noor et al. (Hindawi publishing corporation, Mathematical Problems in Engineering, Volume 2008, Article ID 696734, 11 pages, doi:10.1155/2008/696734) proposed the Variational Homotopy Perturbation Method (VHPM) for solving higher dimentional initial boundary value problems. In this paper, we use the proposed method to obtain the solution of Cauchy reaction-diffusion prob...
We present a scheme which associates to a generalized quasi-variational inequality a dual problem and generalized Kuhn-Tucker conditions. This scheme allows to solve the primal and the dual problems in the spirit of the classical Lagrangian duality for constrained optimization problems and extends, in non necessarily finite dimentional spaces, the duality approach obtained by A. Auslender for g...
Introduction: One of the challenges facing ovarian transplantation is overcoming the ischemia/ reperfusion injury. When blood supply to the implanted tissue is suboptimal (immediate post implant period), ultrasound therapy has been shown to increase mass transport. The aim of this study was to investigate the effect of ultrasound on heterotopic transplantation of mouse ovarian tissue. Methods...
A review of the development and implementation of a 4-year medical student integrated ultrasound curriculum is presented. Multiple teaching and assessment modalities are discussed as well as results from testing and student surveys. Lessons learned while establishing the curriculum are summarized. It is concluded that ultrasound is a well received, valuable teaching tool across all 4 years of m...
The effect of ultrasound waves with low intensity on reducing the time of repair and healing of bone fracture has been known. The present research was undertaken to investigate the effect of ultrasound waves on acceleration of bone growth and, finally, on repair and healing of surgical area using in-vivo animal experiment. In this study, 20 titanium implants with proper dimensions wer...
