Frontal sinus fractures are of surgical importance because of the microbial flora covering the frontal air sinus and it's proximity with the duramater and brain. There is an increased risk of meningitis when fracture of the posterior wall of the frontal sinus is associated with a dural tear. In this condition, communication occurs between the contaminated space of the air sinus and the intr...

In this report we address the problem of non-frontal face verification when only a frontal training image is available (e.g. a passport photograph) by augmenting a client’s frontal face model with artificially synthesized models for non-frontal views. In the framework of a Gaussian Mixture Model (GMM) based classifier, two techniques are proposed for the synthesis: UBMdiff and LinReg. Both tech...

Introduction: Paranormal beliefs are defined as believing in extrasensory perception, precognition, witchcraft, and telekinesis, magical thinking, psychokinesis, superstitions. Previous studies corroborate that executive brain functions underpin paranormal beliefs. To test causal hypotheses, neurophysiological studies of brain activity are required. Method: A sample of 20 students (10 females,...

b a c k ground: several studies have indicated that executive dysfunction is the main neuropsychological feature of parkinson’s disease (pd). the frontal assessment battery (fab) is a short tool for the assessment of executive functions. p u r p o s e : the aim of this study was to determine the relationship between persian version of fab scores and age, education, mini-mental state examination...

adenoid cystic carcinoma (adcc) is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1). about 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1). three clinically obvious characteristics of adcc include slow growth rate, perineural invasion and high incidence of distant metastasis (1). the most commonly-affected sites of...

purpose : to report an unusual case of dermoid cyst of the frontal bone case report : we report a case of 28-year-old man with a history of painless progressive proptosis of the left eye. ct-scan was showed a hypodense lesion that mainly located within the frontal bone with only a small intraorbital involvement. excisional biopsy was performed and histopathologic examination was compatible with...

Frontal lobe syndromes, better termed as frontal network systems, are relatively unique in that they may manifest from almost any brain region, due to their widespread connectivity. The understandings of the manifold expressions seen clinically are helped by considering evolutionary origins, the contribution of the state-dependent ascending monoaminergic neurotransmitter systems, and cerebral c...
