Slow channel inhibitor effects on brain function: tolerance to severe hypoxia in the rat. (1/2)

1. The protective effects of ten slow channel inhibitor drugs against severe progressive hypoxia were investigated in rats breathing spontaneously during light anaesthesia. Respiration, heart rate, electrocorticogram (ECoG) and/or electroencephalogram (EEG) were recorded. 2. Tolerance times were monitored from hypoxia onset until cessation of respiration, ECoG, EEG synchronization, and 'background-EEG'. Drugs were administered i.v. 5 min before the onset of hypoxia. 3. Verapamil, gallopamil, and nimodipine resulted in a significant increase of tolerance times; fendiline and bepridil showed a small increase (not significant); bencyclan and prenylamine were ineffective; cinnarizine and diltiazem slightly reduced tolerance times as did flunarizine at low doses. 4. At protective doses, verapamil, gallopamil, and nimodipine significantly raised the respiration rate but had little or no cardiac depressor effects. Bencyclan showed ventilatory drive but cardiocirculatory depression. A clear-cut ventilatory drive did not occur with the other ineffective slow channel inhibitors. 5. It is suggested that the protective actions observed were not due to slow channel inhibition per se, nor to spasmolytic potency or increased cerebral blood flow. Ventilatory drive associated with other cardiopulmonary actions which secondarily raise the brain oxygen supply are likely to be responsible for this effect.  (+info)

Comparative studies of cerebral vasodilators on relaxation activities in isolated basilar, mesenteric and pulmonary arteries of rabbits. (2/2)

Effects of cerebral vasodilators such as bencyclane, cinnarizine, and papaverine were comparatively studied using helically cut basilar and superior mesenteric arteries and radial muscle preparations of pulmonary arteries with the sympathetic nerve isolated from rabbits. The order of relaxation activities on high K+-induced contractures was cinnarizine>bencyclane>papaverine in basilar strips and cinnarizine>papaverine>bencyclane in mesenteric strips. Relaxation responses of basilar strips to cinnarizine and bencyclane were faster and more marked than those seen in mesenteric strips. Responses to papaverine were equipotent in both preparations. The action of cinnarizine alone was irreversible. In mesenteric strips, the order of the sensitivity of contractile responses to cumulatively applied biogenic amines was serotonin>noradrenaline>histamine. Cinnarizine produced an antihistaminergic action, while bencyclane produced an antiserotonergic action. In pulmonary arteries, 6 x 10(-6) g/ml papaverine inhibited contractile responses to 2, 5, and 25 Hz nerve stimulation in a frequency-independent manner together with inhibition of responses to noradrenaline. Bencyclane at 6 x 10(-6) and 10(-5) g/ml selectively inhibited in a dose-dependent manner contractile responses only to 25 Hz without inhibition of responses to noradrenaline. These results were discussed in comparison with findings of the cerebral vasodilators obtained using other experimental techniques. Spiral strips of basilar arteries from rabbits in combination with peripheral arteries may be used as a simple quantitative, and reproducible screening method in a preclinical stage for drug evaluation of cerebral vasodilators.  (+info)

Patients with a specific kind of lung cancer may benefit from a Phase III clinical trial offered by the Moores UCSD Cancer Center. The new drug, crizotinib, under development by Pfizer, showed dramatic results in reducing lung cancer tumors in some patients during Phase I and II clinical trials.
In the convergence of information and entertainment there is a conflict between the consumers expectation of fast access to high quality multimedia content through narrow bandwidth channels versus the size of this content. During the retrieval and information presentation of a multimedia application there are two problems that have to be solved: the limited bandwidth during transmission of the retrieved multimedia content and the limited memory for temporary caching. In this paper we propose an approach for latency optimization in information browsing applications. We proposed a method for flattening hierarchically linked documents in a manner convenient for network transport over slow channels to minimize browsing latency. Flattening of the hierarchy involves linearization, compression and bundling of the document nodes. After the transfer, the compressed hierarchy is stored on a local device where it can be partly unbundled to fit the caching limits at the local site while giving the user ...

African Americans (AA) are at an increased risk for cardio and cerebral vascular disease relative to Caucasians (CA) and the underlying impairments manifest as early as the second generation prior to overt signs of risk. The mechanisms of this increased risk are multifactorial; however, evidence suggests that microvascular dysfunction is a primary contributor. This study tested the hypothesis that microvascular function, indexed by the skin vascular conductance (SkVc) response to local heating, is impaired in young otherwise healthy AAs. Furthermore, we hypothesized that AAs have an attenuated cerebral vasodilator response to hypercapnia. To date complete data sets have has been collected on 5 AAs and 6 CAs. SkVc was assessed while the skin was clamped at 34 °C and 40 °C and values were normalized to a maximal value obtained during heating at 43 °C for 30 min. Cerebral vasomotor reactivity (CVMR) was assessed by increases in cerebral vascular conductance (CVC) during a rebreathing protocol. SkVc was
Face recognition takes place within a distinct heritable module of the brain and includes the ability to distinguish between male and female human faces. To identify gender, this module targets a number of sexually dimorphic features, particularly the hue and luminosity of facial skin. Men look browner and ruddier in hue because melanin and blood are more present in their skins outer tissues. Women have a higher luminous contrast between their facial skin and their lips and eyes. Hue seems to provide a fast channel for gender recognition. If the observer is too far away or the lighting too dim, the brain switches to the slow channel and targets luminosity. In addition to assisting gender recognition, the skins hue and luminosity may also alter the observers mental state in a number of areas, ranging from sexual attraction to emotional distancing ...

0008]In some existing approaches, the codeword index is fed back in a differential manner. In other words the difference between a current index and a previous index is fed back rather than the codeword index per se. Another problem with common pilot based closed-loop MIMO schemes relates to errors that occur in the transmission of the differential codeword index. Closed-loop MIMO is typically intended for nomadic UEs for whom channel conditions will not change very quickly. For each given currently used pre-coding matrix, a small subset of possible next codewords is defined, for example those that would most likely be selected from the full set due to slow channel variation. This subset of codewords can be determined in several ways, such as spatial correlation and matrix correlation. If an index associated with this subset is fed back rather than an index from the entire set of codewords, fewer bits are needed. However, if a feedback error occurs the transmitter will keep using the wrong ...

Hydrocarbon reservoirs of fluviatile origin are the product of a number of geological processes acting on a variety of scales. Reservoir characterization must be approached holistically in order to understand these processes fully. Tectonic style produces the macro-architectural framework and influences the behaviour of rivers at a mesoarchitectural scale. Tectonics controls the magnitude, position and development of drainage basins and thus, with climate and local geology, controls the flux of sediment fed into any fluviatile system. Migration of normal faulting may lead to the initiation of drainage basins in previously depositional areas, erosion and reworking thus enhancing reservoir quality. Sediment may be introduced as axial or transverse fluxes. Deducing these contributions in ancient basins establishes basin geometry and the basis for reservoir characterization. Individual river channels are highly susceptible to gradient changes caused by tectonic tilting. This causes slow channel belt ...

It acts by interfering with the signal transmission between vestibular apparatus of the inner ear and the vomiting centre of the hypothalamus by limiting the activity of the vestibular hair cells which send signals about movement.[10] The disparity of signal processing between inner ear motion receptors and the visual senses is abolished, so that the confusion of brain whether the individual is moving or standing is reduced. Vomiting in motion sickness could be a physiological compensatory mechanism of the brain to keep the individual from moving so that it can adjust to the signal perception, but the true evolutionary reason for this malady is currently unknown.[11] When prescribed for balance problems and vertigo, cinnarizine is typically taken two or three times daily depending on the amount of each dose and when used to treat motion sickness, the pill is taken at least two hours before travelling and then again every four hours during travel.[12] However, a recent 2012 study comparing the ...
Cinnarizine is an antihistamine and a calcium channel blocker. Histamines mediate a number of activities such as contraction of smooth muscle of the airways and gastrointestinal tract, vasodilatation, cardiac stimulation, secretion of gastric acid, promotion of interleukin release and chemotaxis of eosinophils and mast cells. Competitive antagonists at histamine H1 receptors may be divided into first (sedating) and second (non-sedating) generation agents. Some, such as Cinnarizine also block muscarinic acetylcholine receptors and are used as anti-emetic agents. Cinnarizine through its calcium channel blocking ability also inhibits stimulation of the vestibular system ...

Lidocaine, also known as lignocaine and sold under the brand name Xylocaine among others, is a local anesthetic of the amino amide type. It is also used to treat ventricular tachycardia.[7][8] When used for local anaesthesia or in nerve blocks, lidocaine typically begins working within several minutes and lasts for half an hour to three hours.[8][9] Lidocaine mixtures may also be applied directly to the skin or mucous membranes to numb the area.[8] It is often used mixed with a small amount of adrenaline (epinephrine) to prolong its local effects and to decrease bleeding.[8] If injected intravenously, it may cause cerebral effects such as confusion, changes in vision, numbness, tingling, and vomiting.[7] It can cause low blood pressure and an irregular heart rate.[7] There are concerns that injecting it into a joint can cause problems with the cartilage.[8] It appears to be generally safe for use in pregnancy.[7] A lower dose may be required in those with liver problems.[7] It is generally safe ...
