Polydactyly with 6 or 7 digits bilaterally, or in all the four limbs at a time in certain cases was the principal finding amongst limb malformations in mice fetuses exposed to cyclophos-phamide in the dose of 10 mg /kg body weight on day 11 of gestation. Duplication of great toe was the most dominant. Augmentation of apoptosis by cyclophosphamide resulting in excessive programmed cell death in ...

Figure 11 Average depth of magma lens reflections beneath ridges versus spreading rate. The curved line shows the depth to the 12003C isotherm calculated from the ridge thermal model of Phipps Morgan J and Chen YJ (1993) Journal of Geophysical Research 98: 6283}6297. Data from different ridges are labeled Reykjanes Ridge (RR), Juan de Fuca Ridge (JdF), Costa Rica Rift (CRR), Lau Basin (Lau), no...

The limb iswidely usedasamodel developmental systemandchanges to gene expression patterns in its signaling centers, notably the zone of polarizing activity (ZPA) and the apical ectodermal ridge (AER), are known to cause limbmalformations andevolutionarydifferences in limb morphology. Although several genes that define these limb signaling centers have been described, the identification of regul...

The purpose of the neural image analysis is to trace the velocities and the directions of moving mitochondria migrating through axons. This paper proposes an automated technique for detecting axon structure. Previously, the detection process has been carried out using a partially automated technique combined with some human intervention. In our algorithm, a consolidated image is built by taking...

Alveolar ridge bone resorption is a biologic phenomenon that occurs following tooth extraction and cannot be prevented. This paper reviews the vertical and horizontal ridge dimensional changes that are associated with tooth extraction. It also provides an overview of the advantages of ridge preservation as well as grafting materials. A Medline search among English language papers was performed ...

The Foundation hotspot–Pacific-Antarctic Ridge (PAR) system is the best documented case of a fast spreading ridge approaching a hotspot and interacting with it. The morphology, crustal structure inferred from gravity anomalies and the chemical composition of the lavas of the axial area of the PAR show evidence of the influence of the hotspot, that is presently located roughly 35 km west of the ...

In this study, structural lineaments and fracture zones of the northern region Central Indian Ridge have been determined using gravity data from XGM2019e_2159 global model. scope, firstly, edge detection performances gradient amplitude tilt angle (THDR), theta map (TM), improved local phase (ILP), logistic (IL) methods evaluated on synthetic examples. The results show that IL method effectively...

INTRODUCTION Vertical augmentation of the alveolar ridge is necessary for extensive resorption of the alveolar ridge. AIM To evaluate treatment outcome after alveolar ridge augmentation by a sandwich osteotomy combined with an interpositional allograft. PATIENTS AND METHODS The deficient alveolar ridges were augmented by a sandwich osteotomy combined with bovine collagen matrix as an interp...
