Retraction and regrowth of frog neural tube neurites have been studied in vitro in control cultures and in the presence of a small, continuously applied electrical field. In control cultures, some degree of retraction was seen in 39% of neurites while 7% were reabsorbed completely. Reabsorption of anodal-facing neurites was at least twice as common, with 67% showing some retraction and 17% almo...

Objective: To investigate the cumulative recurrence rate of pars tensa retraction cholesteatoma on the new staging system established by Japan Otological Society (JOS). Materials and Methods: It is a retrospective study and performed in a tertiary and academic center. The series comprised 71 patients with pars tensa retraction cholesteatoma who underwent surgical treatment by a single surgeon b...

Pathogenic Neisseria express type IV pili (tfp), which have been shown to play a central role in the interactions of bacteria with their environment. The regulation of piliation thus constitutes a central element in bacterial life cycle. The PilC proteins are outer membrane-associated proteins that have a key role in tfp biogenesis since PilC-null mutants appear defective for fibre expression. ...

Upper eyelid retraction is a characteristic feature of thyroid eye disease, including Graves' orbitopathy. In this study, a new surgical technique for correction of lid retraction secondary to Graves' orbitopathy is described. Sixteen eyelids of patients older than 18 years old underwent surgical correction for moderate to severe lid retraction secondary to Graves' orbitopathy. In this procedur...

OBJECTIVE To report that maximum weakening of lateral rectus muscles can improve significant exotropia in primary position, abnormal head posture, retraction, narrowing of palpebral fissure and downshoot in exotropic duannes retraction syndrome. CASE A 12-year-old boy with exotropic Duane syndrome presented with downshoot and globe retraction in attempted adduction. Squint surgery was underta...

Abstract Background Retraction is necessary to access deep areas in the brain and skull base, but prolonged forceful use of fixed retraction might be injurious. Several techniques were developed, concept minimally invasive neurosurgery, eliminate or minimize retractors. The authors discuss technical considerations limits applying dynamic surgery for a variety lesions using different approaches....

Abstract In this article, we show and discuss the results of a quantitative qualitative analysis open citations retracted publications in humanities domain. Our study was conducted by selecting papers domain marking their main characteristics (e.g., retraction reason). Then, gathered citing entities annotated basic metadata title, venue, subject) in-text intent, sentiment). Using these data, pe...

INTRODUCTION Intrathecal baclofen, administered via a Baclofen pump, is used for patients with spasticity. We report here a case of intrathecal catheter retraction following surgery. CASE REPORT A male patient with adrenoleukodystrophy and a baclofen pump implant was admitted to the urology department with bladder stones. A transurethral cystolithotripsy and a suprapubic cystotomy were perfor...

Despite theoretical and physical studies implying that cell-extracellular matrix adhesion geometry governs the orientation of the cell division axis, the molecular mechanisms that translate interphase adhesion geometry to the mitotic spindle orientation remain elusive. Here, we show that the cellular edge retraction during mitotic cell rounding correlates with the spindle axis. At the onset of ...

PURPOSE The purpose is to review the issue of retraction in the scientific literature and to examine the policies on retraction of major biomedical journals. METHOD The historical background of this issue was investigated through a literature search. The Instructions to Authors of 122 major biomedical journals were reviewed for evidence of a policy on the retraction of articles. Editors of th...
