In a patient with a distal common bile duct stone, a fracture of the traction wire of the basket occurring during the performance of mechanical lithotripsy resulted in the impaction of the lithotripter basket with a stone. The impacted lithotripter basket combined with a fracture of the traction wire is a rare complication of endoscopic stone removal. We were able to pull the impacted basket us...

INTRODUCTION Vitreomacular traction syndrome has recently been recognized as a distinct clinical condition. It may lead to many complications, such as cystoid macular edema, macular pucker formation, tractional macular detachment, and full-thickness macular hole formation. CASE PRESENTATION We report a case of vitreomacular traction syndrome with eccentric traction at the macula and a partial...

Wavelet Transform is a mathematical tool for time frequency analysis of non stationary signals like the current waveform in electric traction system. The locomotives used in traction system have different types of traction motors –dc and three phase ac motors with different methods of speed control. Hence technologies will be different depending on the type of locomotives. The nature of the loa...

[Purpose] This study investigated the effect of stretching with lumbar traction on VAS and Oswestry scale scores of lumbar 4-5 herniated intervertebral disc (HIVD) patients. [Subjects] We recruited 20 lumbar 4-5 HIVD patients. [Methods] We performed stretching with lumbar traction for lumbar 4-5 HIVD patients during 4 weeks. The VAS and Oswestry scales were measured before and 4 weeks after the...

OBJECTIVES/HYPOTHESIS Oropharyngeal dysphagia (OPD) is common and costly. In order to improve quality of life for patients and costs to society, better treatments than currently available are needed. The author hypothesized that manual control of the upper esophageal sphincter (UES) is possible by pulling the larynx directly forward with anterior traction on the cricoid cartilage. The purpose o...

PURPOSE Spontaneous resolution of vitreomacular traction syndrome in diabetic patients is a rare phenomenon that has been poorly described in the literature. METHODS Case presentation. RESULTS The authors present a case of spontaneous resolution of vitreomacular traction following intravitreal administration of ranibizumab. CONCLUSIONS In patients with vitreomacular traction syndrome and ...

PURPOSE To describe an association between extrafoveal vitreoretinal traction and intractable chronic pseudophakic cystoid macular edema (CME) by the use of optical coherence tomography (OCT). METHODS In a retrospective case series study, charts and OCT findings of patients who had postoperative recalcitrant pseudophakic CME for at least 6 months and vitreoretinal traction membranes were anal...

Purpose. The purpose of this study was to report a case of bilateral vitreopapillary traction, previously misdiagnosed as papilledema. Methods. A case report is presented of a 47-year-old woman with a prior diagnosis of papilledema, who is shown to have bilateral vitreopapillary traction rather than true optic disc swelling, confirmed by optical coherence tomography (OCT). Results. OCT showed v...

Adherent cells exert tractions on their surroundings. These tractions can be measured by observing the displacements of beads embedded on a flexible gel substrate on which the cells are cultured. This paper presents an exact solution to the problem of computing the traction field from the observed displacement field. The solution rests on recasting the relationship between displacements and tra...

Cells migrate in vivo within three-dimensional (3D) extracellular matrices. Cells also migrate through 3D longitudinal channels formed between the connective tissue and the basement membrane of muscle, nerve, and epithelium. Although traction forces have been measured during 2D cell migration, no assay has been developed to probe forces during migration through confined microenvironments. We th...
