BACKGROUND Quitting tobacco or alcohol use has been reported to reduce the head and neck cancer risk in previous studies. However, it is unclear how many years must pass following cessation of these habits before the risk is reduced, and whether the risk ultimately declines to the level of never smokers or never drinkers. METHODS We pooled individual-level data from case-control studies in th...
Objective: The aim of this study was to evaluate the muscular activity timing during running in male children with forward head posture compared to healthy control ones. methods: 12 healthy male children with forward head posture (age: 11.7±1.4 years; height: 149.7±6.2 cm; Mass: 38.0±4.7 kg) and 16 healthy male children (age: 11.8±1.5 years; height: 148.2±6.6 cm; mass: 39.6±0.4 kg) were volunt...

statement of problem: few longitudinal studies have evaluated the reproducibility of natural head position (nhp) with more than six months follow-up. purpose: the present investigation was conducted to estimate the reproducibility of nhp in adult cases after three years. materials and methods: this descriptive study was performed on 27 volunteer dental students, 19-29 years of age. one radiogra...
background head injury is a major health problem worldwide, especially in children (1). trauma is one of the most common causes of morbidity and mortality in developed societies. traumatic injuries to the head can occur because of motor vehicle crashes, falling from heights, being beaten, and brain injuries caused by child abuse (4). the most common causes of head trauma in children are child a...
PURPOSE To evaluate the suitability of a 12- or 32-channel head coil and of a prescan normalization filter for functional magnetic resonance imaging (fMRI) studies at different brain regions. MATERIALS AND METHODS fMRI was obtained from 36 volunteers executing a visually instructed motor paradigm using a 12-channel head matrix coil and a 32-channel phased-array head coil with and without pres...
An experiment to assess psychomotor performance before and after forward-facing (-Gx) impact was conducted using the AFAMRL Horizontal Decelerator Facility. There were 10 volunteer subjects who participated in 50 tests at 4 impact levels (0 G or sham, 8 G, 10 G, and 12 G). Two initial head positions were explored at the highest impact level. The manikin psychomotor task, a complex reaction time...
BACKGROUND Advanced carcinoma of the head represents a substantial health problem in cats for local control and overall survival. OBJECTIVES Evaluate the capability of electrochemotherapy (ECT) to improve bleomycin efficacy in cats with periocular carcinoma and advanced carcinoma of the head. ANIMALS Twenty-one cats with periocular carcinoma (17 squamous cell carcinoma [SCC] and 4 anaplasti...
Two months after a gunshot wound to the head of a 12-year-old boy, MR imaging outlined an asymptomatic false aneurysm of the carotid artery. The scan's ability to image in multiple planes with noninvasive visualization of pulsatile vessel flow suggests its use for follow-up examinations of traumatic injuries to the head or neck.
an appropriate method to determine the hydraulic conductivity above water table is guelph permeameter. using this method, experiments can be carried out by one person in a short period. several investigators have commented on the systematic difference between the hydraulic conductivity obtained by guelph permeameter and shallow well pumping test (swpt) methods. therefore, the purpose of this re...
