Assessing the validity of a linear inflation method in noninvasive blood pressure monitoring during the induction period of general anaesthesia.

Inflationary noninvasive blood pressure (iNIBP) monitoring can determine BP in a shorter time compared to conventional deflationary NIBP (dNIBP) monitoring. We assessed the efficacy of iNIBP monitoring during induction of general anaesthesia and tracheal intubation, which can cause rapid changes in haemodynamics. Our study included 14 surgery patients receiving tracheal intubation under general anaesthesia.

Interaction between transcellular and paracellular water transport pathways through Aquaporin 5 and the tight junction complex.

To investigate potential physiological interactions between the transcellular and paracellular pathways of water transport, we asked whether targeted deletion of Aquaporin 5 (AQP5), the major transcellular water transporter in salivary acinar cells, affected paracellular transport of 4-kDa FITC-labeled dextran (FITC-D), which is transported through the paracellular but not the transcellular route. After i.v.

Morphological changes in the rat sublingual gland parenchyma with aging.

Background: The characteristics of mucous cells in the aging rat sublingual gland were investigated in this study. Particular attention was paid to accumulated amyloid protein and changes of the properties of the secretory granules at the histochemical and ultrastructural level.

Objective: This study was designed to examine age-related morphological changes in the sublingual gland of male Wistar rats from 12 to 27 months.

Granule types and their morphological changes in terminal cluster and acinar cells in the late pre- and early postnatal rat sublingual gland.

The developmental characteristics of serous cells appearing in the rat sublingual gland from the late prenatal to the early postnatal period were investigated in this study. Particular attention was paid to the morphological changes observed in the secretory granules at the histochemical and ultrastructural level. On prenatal day 18, granules with homogeneous high electron density (Type I granules), and mottled granules (Type II granules) with heterogeneous electron density appeared in the narrow luminar cytoplasm of cells constituting the terminal clusters.

Morphological changes in mouse sublingual gland parenchyma subjected to chorda tympani resection.

Morphological changes in the mouse sublingual gland parenchyma subjected to parasympathetic nerve block were investigated. Mice were subjected to unilateral resection of the chorda tympani, near its point of joining with the lingual nerve. After 1, 2, 3, 5, 10 or 20 weeks, the mice were killed and their sublingual glands were removed and processed for light and electron microscopy.
