Forty patients with recurrent syncopal episodes of uncertain etiology were evaluated with a 60-degree head-up tilt table test for 60 minutes. There were 21 men and 19 women, with a mean age of 36 +/- 19 years, a mean of 7.6 syncopal episodes per patient, and a mean duration of symptoms of 4.2 +/- 6 years. Twelve patients had evidence of organic heart disease. Ten control subjects with no histor...

BACKGROUND/HYPOTHESIS The video Head Impulse Test (vHIT) is now widely used to test the function of each of the six semicircular canals individually by measuring the eye rotation response to an abrupt head rotation in the plane of the canal. The main measure of canal adequacy is the ratio of the eye movement response to the head movement stimulus, i.e., the gain of the vestibulo-ocular reflex (...

To understand the effect of aging on human skin innervation, we investigated intraepidermal nerve fiber (IENF) density of skin biopsies. IENF densities of the distal leg were lower in elderly (> or = 60 years of age) than in young adults (19-39 years of age; 7.80 +/- 0.79 vs 13.55 +/- 0.85 fibers/mm, p < 0.01). A similar trend was also observed in the distal forearm (11.67 +/- 1.55 vs 19.39 +/-...

BACKGROUND Chlamydia pneumoniae is drawing increasing attention as an agent of respiratory tract infection. Specific antibody prevalence in western countries is low in preschool children and reaches more than 50% in adults. However, little is known about the prevalence of this infection in immunocompromised subjects such as HIV-I infected patients. The aim of this study was to evaluate the sero...

Objective.

Background: As per ICMR study in April 2020, around 30% of all the proven cases COVID-19 were asymptomatic and various modeling studies had estimated that 40% transmission was by patients. So, it decided to isolate such patients at dedicated covid care centers order stop corona virus. Methods: This a cross-sectional conducted center (DCCC) metropolitan region from 27 June, 2020 10 July, 2020. A...

AIMS To analyse age-related changes of human conjunctiva by in vivo laser scanning confocal microscopy (LSCM). METHODS 80 healthy subjects were enrolled and divided into four groups according to age: A (0-19 years), B (20-39 years), C (40-59 years) and D (over 60 years). In vivo LSCM was performed on the subjects' bulbar conjunctivas, and the images were recorded. The morphology and densities...

INTRODUCTION In combination with multivariate pattern analysis algorithms such as Support Vector Machines (SVM) [1] or Support Vector Regression (SVR) [2], functional connectivity offers a powerful tool for brain classification. With this approach, several groups have successfully identified and predicted brain characteristics using resting-state MRI data [35]. Specifically, Dosenbach et al. ha...
