among the therapeutic options for achalasia are pneumatic dilatation (pd), an appropriate long-term therapy, and botulinum toxin injection (bt) that is a relatively short-term therapy. this study aimed to compare therapeutic effect of repetitive pneumatic dilation with a combined method (botulinum toxin injection and pneumatic dilation) in a group of achalasia patients who are low responder to ...

the objective of this paper is to establish a complete characterization of multiwavelet packets associated with matrix dilation on general lattices $gamma$ in $mathbb r^d$ by virtue of time-frequency analysis, matrix theory and operator theory.

the structure of the sheep cervix limits the application of reproductive biotechnologies such as embryo transfer and artificial insemination. the aim of this study was to determine differences in cervical anatomy and morphology between sanjabi lambs and ewes, and the relationship between cervical anatomy and cervical penetration in ewes. four hundred and sixty eight postmortum cervices belongin...

EPIDURAL analgesia is currently the most effective method available to treat pain in labor. Retrospective studies conducted during the 1980s and 1990s suggested that epidural analgesia might slow the progress of labor and cause unnecessary Cesarean sections. Unfortunately, retrospective study cannot readily separate cause and effect. If patients with slower labor are more likely to receive epid...

objectives major differences exist in the anatomy and biomechanics of the growing spine that causes failure patterns different from those in adults. spinal injury in the pediatric patient is a main concern because timely diagnosis and appropriate treatment can prevent further neurologic damage and deformity and potentiate recovery. we conducted a retrospective clinical study of 137 cases (93 bo...

geometrical profile (roughness) of joint surfaces influences the behaviour of rock joints under shear loading. with regard to the dilation, there are two models of direct shear test that may simulate the original loading condition existing in the location from where the specimens have been sampled. the first model in which the normal load is constant (cnl) and the discontinuity is free to dilat...
