background: parkinson's disease as a progressive disorder of the nervous system leads to the disability of postural control system. objectives: in the present study the effects of pilates exercises on functional balance in patients with parkinson's was investigated. materials and methods: this control trial included 30 patients with idiopathic parkinson's disease who were selecte...

STATEMENT OF PROBLEM Dentin and core materials that substitute for missing dentin are dissimilar materials. A core material with a lower elastic modulus may deform more under applied stress and therefore result in reduced stress concentration at the core/dentin junction. PURPOSE This in vitro study examined the effect of core stiffness on the fracture resistance and failure characteristics of...

The purpose of this study was to determine the fracture resistance of 4 post and core systems. 40 extracted maxillary canines (for orthodontic reason) were used for this study. The samples were divided into 4 groups, which were: Group (1) Cast post luted with Rely X ARC; Group (2) Cast post cemented with zinc phosphate; Group (3) Fibre post luted with Rely X + Filtek Z-250 as core material; Gro...

STATEMENT OF PROBLEM Studies concerning the effects of post-core design and ferrule on the fracture resistance of endodontically treated teeth remain controversial. PURPOSE The purpose of this study was to investigate in vitro the effects of post-core design and ferrule on the fracture resistance of root canal treated human maxillary central incisors restored with metal ceramic crowns. MATE...

Background Individuals with overweight and obesity (OW/OB) have poor performance in weight-bearing exercises, resulting low functional capacity. The dynamic neuromuscular stabilization (DNS) technique was created to engage the core-postural chain conjunction core muscles, generating enough intra-abdominal pressure dynamically support spine through muscular activity. DNS is a strategy that empha...

ABSTRACT I examine the assumption that jets shape axisymmetrical morphological features of core-collapse supernova (CCSN) remnants are post-kick jets, i.e. neutron star (NS) launches these after explosion and it acquired its natal kick velocity. find this implies pre-collapse cores CCSN progenitors have sufficient angular momentum fluctuations to support jittering explode star. From finding sha...
