Introduction: Children represent the most vulnerable age group for initiation and use of nicotine. Nicotine use in this age group is of grave concern because of associated physical, mental co-morbidities. Moreover, many of them graduate to use of harder substance longitudinally in their lifetime. Aims and Objective: To study profile of Nicotine users of child and adolescents age group among sub...

Monocular and binocular contrast sensitivity function for a range of spatial frequencies was measured in two groups of subjects with normal vision. Statistically significant differences in performance between the younger group (age 20-30 years) and the older group (age 50-87 years) were found at all spatial frequencies sampled between 0.40 and 19 X 25 cpd. In the age range 50-87 years there was...

1. A method is described enabling the determination of fat, water, electrolytes, protein, DNA, RNA and total creatine in a single sample of human muscle obtained by the percutaneous needle-biopsy technique. The amino acid content can also be analysed in the same muscle sample. 2. Fifty healthy subjects were studied: 29 between 19 and 40 years of age, 11 between 41 and 60 years of age, and 10 be...

OBJECTIVES The aim of this study was to describe the natural history of asymptomatic ventricular pre-excitation in children and to determine predictors of potentially life-threatening arrhythmic events. BACKGROUND Sudden death can be the first clinical manifestation in asymptomatic children with ventricular pre-excitation, but reduction of its incidence by prophylactic ablation requires the i...

The ultrasonic cardiac output monitor (USCOM) is a noninvasive transcutaneous continuous wave Doppler method for assessing hemodynamics. There are no published reference ranges for normal values in adults (aged 18-60 years) for this device. This study aimed to (1) measure cardiovascular indices using USCOM in healthy adults aged 18-60 years; (2) combine these data with those for healthy childre...

The present study examined the relationship among body composition, measures of self-rated health and activities of daily living in a group of free living elderly aged >60 years belonging to poor economic status. A sample of 147 subjects (82 males, 65 females) from Tirupati suburbs of Andhra Pradesh, India was selected. The subjects were divided into three age groups i.e. 60-69, 70-79 and >80 y...

The purpose of this study was to examine the effect of practice on simple reaction time (RT), movement time (MT), and response consistency for two arm-reaching tasks of graded complexity in younger and older adults. Forty subjects, 20 younger adults (age range = 20-29 years) and 20 older adults (age range = 60-82 years), were randomly subdivided into practice and control groups. All subjects we...

The aim of the study was to investigate the range of mandibular movements and to analyze the difference in range of mouth opening, right and left lateral movements, and protrusive movement between patients with clinical diagnoses of temporomandibular disorders and asymptomatic subjects (control group) in a young male population. A total of 240 subjects, aged 19-28, were included in the study. T...

PURPOSE To develop a near-infrared spectroscopic method to identify breast cancer biomarkers and to retrospectively determine if benign and malignant breast lesions could be distinguished by using this method. MATERIALS AND METHODS The study was HIPAA compliant and was approved by the university institutional review board. Written informed consent was obtained. By using self-referencing diffe...

The role of Dermatophagoides (D.) pteronyssinus in atopic dermatitis (AD) was investigated by use of skin prick test (SPT) and total and specific IgE (RAST) to D. pteronyssinus. The study included 43 patients (17 male and 26 female), mean age 42.3 (range 19-77) years. All study patients met the Hanifin and Rajka criteria. Patients were divided into two groups: "pure" AD (n=27; 12 male and 15 fe...
