Two membranous sacs within the vestibular labyrinth of the INNER EAR. The saccule communicates with COCHLEAR DUCT through the ductus reuniens, and communicates with utricle through the utriculosaccular duct from which the ENDOLYMPHATIC DUCT arises.

To generate Ih activation curves with minimal contamination, tail currents were measured at −74 mV, near the reversal potential for the potassium-selective inward rectifier, IK1. The tail current was sampled at the moment of the step to −74 mV and plotted against prepulse potential. Conductance was calculated by dividing the Ih tail current by the difference (30 mV) between the step potential (−74 mV) and the experimentally determined reversal potential (−44 mV, as measured from type II hair cells in the presence of 500 μm BaCl2, which blocked IK1). Type II vestibular hair cells had a maximum conductance of 4.4 ± 2.6 nS, a half-activation voltage (V1/2) of −99 ± 6 mV, and a slope factor (S) of 8.5 ± 1.9 mV (n = 41; Fig. 2C). Under our experimental conditions, the conductance of Ih was slightly larger than previously reported in mouse vestibular hair cells (Rüsch et al., 1998), perhaps due to differences in the age of the cells or rundown of Ih. Because Ih can be modulated by a ...
The vitamin A-derived morphogen retinoic acid (RA) plays important roles during the development of chordate animals. The Aldh1a-family of RA-synthesizing enzymes consists of three members, Aldh1a1-3 (Raldh1-3), that are dynamically expressed throughout development. We have searched the known teleost genomes for the presence of Raldh family members and have found that teleost fish possess orthologs of Aldh1a2 and Aldh1a3 only. Here we describe the expression of aldh1a3 in the zebrafish, Danio rerio. Whole mount in situ hybridization shows that aldh1a3 is expressed during eye development in the retina flanking the optic stalks and later is expressed ventrally, opposite the expression domain of aldh1a2. During inner ear morphogenesis, aldh1a3 is expressed in developing sensory epithelia of the cristae and utricular macula and is specifically up-regulated in epithelial projections throughout the formation of the walls of the semicircular canals and endolymphatic duct. In contrast to the mouse inner ...

Do you sense ringing in your ears? Acoustic neuroma is a condition in which tumor is formed on the cranial nerve connecting the middle ear and the brain. Acoustic neuroma can cause hearing loss and impair brain functions such as balancing, muscle control, facial expressions, etc. If any of these symptoms of acoustic neuroma are experienced by you, consult your physician regarding treatments. Surgery is usually performed to remove acoustic neuroma while preventing any damage to the ear and brain.

Danish researchers have found no support for Lennart Hardell and Kjell Hansson Milds contention that mobile phones increase the risk of acoustic neuromas. A team led by Christoffer Johansen of the Danish Cancer Society in Copenhagen compared the histories of 106 cases of acoustic neuromas, benign tumors of the cranial nerve, with those of 212 controls. There was no elevated rate of cancer, even among those who had used a cell phone for ten years or more.
A new mineral, metathénardite, ideally Na2SO4, the high-temperature hexagonal dimorph of thénardite, a natural analogue of the synthetic phase Na2SO4(I), was found in the sublimates of active fumaroles at the Second scoria cone of the Northern Breakthrough of the Great Tolbachik Fissure eruption, Tolbachik volcano, Kamchatka, Russia. The holotype originates from the Glavnaya Tenoritovaya fumarole in which metathénardite is associated with hematite, tenorite, fluorophlogopite, sanidine, anhydrite, krasheninnikovite, vanthoffite, glauberite, johillerite, and lammerite.

Specific subpopulations of lung-related primary afferent neurons in dorsal root and vagal sensory ganglia have been reported to express P2X2 and P2X3 receptors both in the neuronal cell bodies and in their peripheral terminals. The afferent innervation of airways and lungs is organised as sensory receptor structures, of which at least seven types with a vagal origin and two with a spinal origin have been reported. In view of the recently suggested therapeutic promise of ATP antagonism - specifically at P2X3 receptor expressing nociceptive fibres - in respiratory disorders, the present work focusses on four distinct populations of pulmonary sensory receptors that have so far been reported to express P2X2/3 receptors ...

Developed in 2007-2008, diameter 0.9 mm, steering range: ±90º in all directions.. The retina is a light-sensitive layer at the inside of the eye. The macula is the region at the center of the retina with the highest concentration of light-sensitive cells. Macula degeneration - a disease which is a major cause of blindness - is caused by a disfunctioning choroid layer under the macula. A way to treat macula degeneration is to perform surgery to the choroid layer via a tiny incision in the retina near the macula. Reaching the choroid layer under the macula is extremely difficult as the surgeon has to operate through the incision under an angle while avoiding damage to the extremely delicate macula layer. A steerable instrument could potentially solve this issue by making it easier to steer the instrument through the incision.. The largest design and fabrication challenge of such an instrument is the extreme miniaturization of the steerable mechanism in the tip. Down-scaling our patented ...
