To examine the pathomechanism of entrapment neuropathy associated with diabetes with special emphasis on the roles of mast cells and Tenascin-C using a rat model of Streptozotocin-induced diabetes. The roles of mast cells and Tenascin-C in development of tarsal tunnel syndrome were analyzed electrophysiologically and histologically in 20 male Ws/Ws-/-rats (mast cell deficient) and 20 of their m...

abstract   background: the pathophysiology of carpal tunnel syndrome is associated with increased intracarpal canal pressure. recently, palmaris longus has been introduced as an independent risk factor for the development of carpal tunnel syndrome. the purpose of this study was to assess the association of carpal tunnel syndrome with the presence of palmaris longus tendon and functional superfi...

To solve the technical problems of slow construction progress, low mechanization and high risk shallow buried large cross-section tunnels in a complex urban environment, series spatial reticulated shell (SRS) support structures are developed this paper. Moreover, equipment multifunctional operation trolley is to install SRS arch, technology system prefabricated structure proposed for tunnel. Th...

Purpose. This work aims to study the tunnel face stability (Algiers subway Tunnel) and evaluate common numerical procedures that are used for analyzing stability. Two-dimensional (2D) three-dimensional (3D) Finite Element (FE) modeling using PLAXIS programs. Methodology. Tunneling is executed by NATM method; two types of calculations used. The first one done reducing applied pressure until coll...

The existence of giant karst cave can cause collapse and water inrush hazards during the excavation tunnel, causing serious economic losses. In this paper, based on FEA software MIDAS, a numerical simulation model for backfilling large through cross-section tunnel was established. distribution characteristics change rules displacement field, stress horizontal support stress, plastic zone surrou...

In some subsurface urban development projects, bedrock faults intersecting with the tunnel path are inevitable. Due to high costs of it is necessary study behavior such concrete structures under fault movement risks. Using an advanced 3D numerical finite difference code and a plastic hardening constitutive model for soil, this paper examined performance straight oblique segmented Tabriz Subway ...

BACKGROUND Wrist anthropometrics and posture have been implicated in the development of carpal tunnel syndrome, yet it remains unclear how external measurements relate to carpal tunnel parameters in neutral and non-neutral postures. The purposes of this study were (i) to evaluate the effect of slice orientation on several indices of carpal tunnel size and shape and (ii) to examine the relations...
