Conventional uvulopalatopharyngoplasty has in the last years to an increasing extent been succeeded by a variety of laser procedures for snorers obstructed by lax palates only. These surgical techniques have the advantages of being less traumatic and therefore more suitable for local anesthesia and
BACKGROUND
Atropine (Atr) and scopolamine (Scp) are toxic secondary plant metabolites of species within the Solanaceae genus that can accidentally or intentionally reach the food store chain by inaccurate harvesting of any plant material, e.g. for herbal tea infusions. Ingestion may cause severe
Methods for the accomplishment of small-molecule imaging by mass spectrometry are challenged by the need for sample pretreatment steps, such as cryo-sectioning, dehydration, chemical fixation, or application of a matrix or solvent, that must be performed to obtain interpretable spatial distribution
The present study attempted to evaluate the effects of inhibition of cortical muscarinic receptors on the increase in cortical blood flow (laser-Doppler flowmetry) elicited by chemical stimulation of the periaqueductal gray matter in 28 anesthetized rats with cervical cordotomy. A new device was
Evidences indicate that inhibition of central Renin angiotensin system (RAS) ameliorates memory impairment in animals and humans. Earlier we have reported involvement of central angiotensin converting enzyme (ACE) in streptozotocin induced neurodegeneration and memory impairment. The present study
BACKGROUND
Noni (Morinda citrifolia L.) is widely used for different illnesses including CNS disorders. Recently Noni has been reported to prevent amyloid beta induced memory impairment in mice. However, the influence of Noni on cholinergic system has not been explored so far. Therefore, present
BACKGROUND
Inhibition of renin-angiotensin system (RAS) improves cognitive functions in hypertensive patients. However, role of AT1 and AT2 receptors in memory impairment due to cholinergic hypofunction is unexplored.
OBJECTIVE
This study investigated the role of AT1 and AT2 receptors in cerebral
The centromedian-parafascicular complex (CMPf) of the intralaminar thalamus was stimulated in anesthetized, ventilated rats, and cerebral cortical perfusion was continuously measured using laser Doppler flowmetry. Stimulation led to a frequency- and intensity-dependent increase in cortical perfusion
This is a case report followed by a short review of literature of apocrine hidrocystomas. A 67 year old lady came to this clinic with multiple translucent, asymptomatic papulocystic lesions on the face which got worse in summer. A biopsy showed a single cystic cavity lined by two layers of small
OBJECTIVE
To investigate the influence of acetylcholine (Ach) on gap junctional intercellular communication in rat hippocampus.
METHODS
Ach was applied to primary co-cultured hippocampus neurons and glial cells. Laser scanning confocal microscopy was used to monitor the change of Ca(2+) in the
The laterodorsal tegmental nucleus (LDT) is the largest aggregation in the brainstem of cholinergic neurons whose axons reach the thalamus as part of a diffuse projection to the forebrain. We measured the regional blood flow in the thalamus by means of laser Doppler flowmetry, and examined whether
In the present study, we have investigated transdermal administration of ligustrazine phosphate (LP), as an antioxidant, for the treatment of Alzheimer's disease (AD). The LP transdermal ethosomal system was designed and characterized. Franz-type diffusion cells and confocal laser scanning
The effects of amino acids Gln and Lys on the antioxidant ability of peptides were investigated in this study. The identified peptides Lys-Met-Asp-Asp-Lys (KMDDK), Lys-Met-Asp-Asp-Gln (KMDDQ), Gln-Met-Asp-Asp-Lys (QMDDK), and Gln-Met-Asp-Asp-Gln (QMDDQ) were used to investigate their antioxidant
In addition to camouflage and chemical toxicity, many caterpillars defend themselves against predators with sudden sharp movements. For smaller species, these movements propel the body away from the threat, but in larger caterpillars, such as the tobacco hornworm, Manduca sexta, the movement is a
The midbrain periaqueductal gray matter has been identified as a reflex centre located uppermost in the central organization of diverse defensive reactions. We recently found that when activated, the caudal third of the lateral periaqueductal gray was also capable of provoking a marked increase in
