Background and Objectives: Fine needle aspiration cytology (FNAC) is an established out- patient procedure used in primary diagnosis of palpable thyroid lesions. A modified technique fine needle capillary sampling (FNCS) obviates the need of suction, is less painful, patient friendly and reported to overcome the problem of inadequate and bloody specimens. The aim of our study was to compare the...

The preceding paper 1 of this series describes the preparation of "megapermselective" collodion membranes which are extremely impermeable to anions, but at the same time are very permeable to univalent cations. The purpose of the present paper is to describe the preparation and the properties of analogous electropositive "megapermselecfive" membranes which are very impermeable to cations, but a...

Frailty models are often used in survival analysis to model multivariate time-to-event data. In infectious disease epidemiology, frailty models have been proposed to model heterogeneity in the acquisition of infection and to accommodate association in the occurrence of multiple types of infection. Although traditional frailty models rely on the assumption of lifelong immunity after recovery, re...
