In this article, we study the smoothness of Riemannian submersions for open manifolds with non-negative sectional curvature. Suppose thatM is a C-smooth, complete and non-compact Riemannian manifold with nonnegative sectional curvature. Cheeger-Gromoll [ChG] established a fundamental theory for such a manifold. Among other things, they showed that M admits a totally convex exhaustion {Ωu}u≥0 of...

The twiddler syndrome results in retraction and coiling of the lead in the pacemaker pocket with subsequent pacemaker malfunction. If the lead׳s parameters are not affected, then the problem can be corrected by lead repositioning. We describe the first reported case of a dramatic pacemaker lead coiling with a double level of lead compromise, with one of them being intra-cardiac. This condition ...

objective: the gingival crevicular fluid (gcf) is an inflammatory exudate found in the gingival sulcus. the forces exerted during orthodontic treatment cause distortion of the periodontal ligament (pdl) extra-cellular matrix, resulting in some biological features that can lead to modification of both gcf volume and its components. the present study investigated the effect of orthodontic tooth m...

apert syndrome is a genetic defect which was first described by eugene apert in 1906. it's incidence is approximately one in 50000 births. this syndrome is many abnormalities in your body and central nervous system. rehabilitation can increase children and their parent's quality of life.we report a case of apert syndrome and his occupational therapy program.

Background: Neonates are at high risk for health problems. Without proper treatment, those problems might lead to either disability or death. Congenital heart disease causes respiratory distress syndrome (breathing syndrome), with symptoms of dyspnea, cyanosis, and arrest due pathological changes in the that disrupt blood flow cycle throughout body. This study aimed discover nursing care Baby M...

PURPOSE To describe a series of patients with lower eyelid epiblepharon associated with lower eyelid retraction. METHODS We retrospectively reviewed the medical records of patients who underwent surgery for lower eyelid retraction, epiblepharon, or thyroid-associated ophthalmopathy (TAO) between October 1999 and March 2007. Patients with both lower eyelid retraction and epiblepharon on preope...

Twiddler syndrome refers to a rare complication observed in patients with implanted pacemakers or defibrillators that causes device malfunction. The condition arises as a result of the patient’s conscious or unconscious manipulation of the device, causing its rotation in the pocket, resulting in torsion and dislodgment of the implanted lead(s). A 65-year-old obese woman with idiopathic dilated ...
