Background: Injury to the infrapatellar branch of the saphenous nerve (IPBSN) is common after arthroscopic ACLreconstruction with hamstring tendon autograft, as reported in up to 88% of the cases. Due to close relationshipbetween the IPBSN with pes anserine tendons insertion skin incision may sever IPBSN while harvesting gracillis andsemitendinous tendons. As the IPBSN course at the anterior of...

purpose: superior oblique palsy is a common cause of paralytic strabismus. this disorder causes diplopia, head posture and facial asymmetry. this retrospective study reviews patient with superior oblique (so) palsy operated at labbafinejad medical center from 1997 to 2007. methods: in this descriptive study, records of patients with so palsy scheduled for surgery were reviewed. forced duction t...

A case of acute esotropia with bilateral inferior oblique muscle overaction in a 4-year-old boy with a posterior fossa pilocytic astrocytoma is reported. After tumor excision, the esotropia and oblique dysfunction resolved. Acute esotropia with bilateral inferior oblique muscle overaction without abducens palsy is an unusual sign of brain stem mass.

The main issue of this work is to investigate asymmetric structures in graphs. While symmetry structures in graphs are well observed, the opposite question has not been investigated deeply so far. It is known from a theorem of Wright, that almost all graphs are asymmetric. The class of asymmetric graphs is restricted further by forbidding even local symmetries. The main question is to determine...

This paper presents a new algorithm of decision rules with oblique conditions induction. It bases on the Fisher’s Linear Discriminant Analysis as a tool of finding an initial classes separation. This technique has a good ability of oblique dependencies generalisation what reduces the number of decision rules and their complexities. Keywords—classification, machine learning, Linear Discriminant ...

BACKGROUND The purpose of this paper is to review different types of superior oblique muscle surgeries, to describe the main areas in clinical practice where superior oblique surgery is required or preferred, and to discuss the preferred types of superior oblique surgery with respect to their clinical outcomes. METHODS A consecutive nonrandomized retrospective series of patients who had under...

Shortening of oblique left ventricular (LV) fibers results in torsion. A unique relationship between volume and torsion is therefore expected, and the effects of load and contractility on torsion should be predictable. However, volume-independent behavior of torsion has been observed, and the effects of load on this deformation remain controversial. We used magnetic resonance imaging (MRI) with...

In the paper proposed we will make use of the gradient flow approach to consider a generalization of the well-known oblique Procrustes rotation problem, involving oblique simple structure rotation of both the core and component matrices resulting from three-mode factor analysis. The standard oblique Procrustes rotations to specified factor-structure and factor-pattern follw as special cases. Th...
