Cortical dispersing depression (SD) is definitely propagating neuronal and glial depolarization and is definitely thought to underly the pathophysiology of migraine. using 5-bromodeoxyuridine labeling and immunohistochemical evaluation. Newly produced astrocytes had been noticed KIF23 just in the SD-stimulated cortex, but not really in the contralateral cortex or in regular cortex. The astrocytes had been generated from proliferating Y-33075 NG2 cells. Astrogenesis relied on the quantity of SD stimuli, and was followed by reductions of oligodendrogenesis. These findings reveal that the cell destiny of NG2 cells Y-33075 was moved from oligodendrocytes to astrocytes depending on SD stimuli, recommending activity-dependent cells redesigning for maintenance of mind features.

An electrode device is disclosed comprising a deformable envelope, further comprising recording electrodes and a pressure recording port. The device allows for monitoring of brain retraction pressure and local cortical electrical activity including DC potential, as well as redistribution of the force applied during retraction and cushioning of the rigid edges of the brain retractor, thereby diminishing the chance of focal brain injury during surgery. Retraction pressure recorded is equal over the full area of contact. A means is disclosed for optional evacuation of air from the system to improve accuracy and fidelity of the pressure measurements. Local brain hypothermia may be induced via the bladder and attached catheter, thereby providing additional neuroprotection during brain retraction. The device also allows for measurement of intracranial pressure, DC potential, EEG and, optionally, other physiologic parameters in epileptic and severe head trauma patients for management of edema and injury.

Spreading depression (SD) is a slowly propagating wave of transient neuronal and glial depolarization that develops after stroke, trauma and subarachnoid hemorrhage. In compromised tissue, repetitive SD-like injury depolarizations reduce tissue viability by worsening the mismatch between blood flow and metabolism. Although the mechanism remains unknown, SDs show delayed electrophysiological recovery within the ischemic penumbra. Here, we tested the hypothesis that the recovery rate of SD can be varied by modulating tissue perfusion pressure and oxygenation. Systemic blood pressure and arterial pO(2) were simultaneously manipulated in anesthetized rats under full physiologic monitoring. We found that arterial hypotension doubled the SD duration, whereas hypertension reduced it by a third compared with normoxic normotensive rats. Hyperoxia failed to shorten the prolonged SD durations in hypotensive rats, despite restoring tissue pO(2). Indeed, varying arterial pO(2) (40 to 400 mm Hg) alone did not

Introduction: It has been reported that cerebral blood flow (CBF) supplied by chest compression (20-40% of control levels) exceeds the CBF threshold for membrane depolarization (20%). However, the CBF threshold for membrane repolarization has not been studied. It is unknown whether chest compression can restore membrane potential. In the present study, we compared the CBF threshold for depolarization with that for repolarization. In addition, the effects of brain hypothermia on the repolarization threshold were evaluated.. Methods: Rats (10 in each group) were anesthetized with isoflurane. CBF was measured by placing a laser-Doppler flow probe placed adjacent to a direct current (DC) potential electrode in the parietal cerebral cortex. Following bilateral occlusion of common carotid artery, CBF was continuously decreased by exsanguination at a speed of 5% of the baseline level every 2 min until a sudden negative DC shift was observed. After 5 or 10 min of ischemic depolarization, the CBF was ...

The epidermis, being relatively drier, initially offers greater resistance to DC flow. The resistance is generally decreased by sweat and moisture or in areas where follicles pierce the epidermis and increased where the epidermis is thicker (eg, on the acral surfaces of the skin). When a DC potential of more than 10 V is established across the skin, the epidermis begins to lose its structural integrity and its resistance further decreases. In a corollary to this property, an electrical current that passes through an initially resistant barrier (eg, epidermis) causes a thermal burn at the area of increased resistance. The epidermal barrier is effectively removed when the skin is immersed in a fluid conducting medium such as water. With a fluid conductor, the flow of current is spread over a broader contact surface, and the water and its attendant ions can more effectively reach portions of the epidermis that are better conductors. For this reason, burns are not seen on the surface of skin ...

An increase in blood pressure will stretch carotid sinus and aortic arch ,which in turn will cause stretching or spreading of nerve endings ,which will increase influx of the sodium ions . Ultimately increase in depolarisation wave will cause stimulation of NTS (Even decrease in depolarisation wave will stimulate NTS ,which happens during decrease in blood pressure).Now as we know there is increase in blood pressure , NTS-our main character in this process will control these 3 centres to control blood pressure. Lets see what it do to these three centres present in medulla oblongata ...

In animal models of focal cerebral ischaemia, usually induced by occlusion of the middle cerebral artery, a spontaneous phenomenon occurs around the periphery of the core territory, with electrophysiological features essentially identical with CSD, and similar capacity to propagate across cerebral cortex. Designated peri-infarct depolarisation (PID), this event is associated with infarct expansion, or recruitment of at-risk cortical territory into the expanding core, and has been shown capable of causing this expansion, in the absence of therapeutic intervention. Indeed it has been hypothesized that glutamate release may be involved in PID generation, and that excitotoxicity may accomplish detrimental effects via this route (Hossmann, K. A. 1994), (Obrenovitch, T. P. and Urenjak, J. 1997). Some experimental neuroprotection treatments for stroke act to decrease the incidence of PID (Iijima, T. et al. 1992;Chen, Q. et al. 1993;Busch, E. et al. 1996 ...

Efficient translation of human rhinovirus-2 (HRV-2) RNA from its internal ribosome entry site (IRES) depends on the presence of cellular trans-acting factors upstream of N- ras (unr) and polypyrimidine-tract-binding protein. unr contains five cold-shock domains (CSDs) and is predicted to act as an RNA chaperone, allowing the HRV-2 IRES to attain the correct conformation for ribosome binding. To investigate the role of each of the CSDs in IRES-dependent translation, five unr mutants, each harbouring a point mutation in a different CSD, were generated. All five mutants were severely impaired in their ability to bind to the IRES and to stimulate translation from it. This showed that the ability of unr to function as an activator of HRV-2 RNA translation requires the RNA-binding activity of all five CSDs.

Migraine is a prevailing disease in present day population.

Thanks for the quick reply. Your code works as you described and as I requested, but I dont think I explained what I needed very well. Your code creates each series as an element in the array (each line of data is an element), but I need to be able to separate out the PID data in order to work with it. I need the user to log what user was involved, and I need the time to be able to sort the list and choose the 10 oldest PIDS for the day. To illustrate, heres the same data:. ...

Ten to fifteen percent of all patients with migraine suffer from migraine with aura. For most of these patients the aura phase encompasses visual or sensory deficits for 30 to 60 minutes, and in a few cases for several hours. Using high field functional magnetic resonance imaging with near continuous recording during visual aura, cortical spreading depression (CSD)-like events in the human occipital cortex could be visualised,1 confirming the concept of a transient slowly spreading excitation (depolarisation), followed by long lasting depression as the underlying mechanism of migraine aura. Despite the recent development of abortive migraine drugs such as 5-hydroxytryptamine 1B/D agonists, suitable agents for suppressing the frequency and duration of migraine aura have not been identified. Based on concepts of emphasising CSD-like events in migraine pathogenesis, anti-glutamatergic strategies have been suggested as a potential avenue for the treatment of migraine auras.2. Lamotrigine is a potent ...

DEAR DR. ROACH: I am a healthy 64-year-old woman. My only medication is atenolol for blood pressure. I get the aura of migraines very often. The light flashing in my peripheral vision and then in front of my eyes always lasts between 30-45 minutes, no more. Then it is gone, leaving me with a tired, slightly dull pain in my eyes and head. I never get the horrible pain and nausea that normally are associated with a migraine headache. If I can, I go into a dark area, close my eyes for the time it is happening, and then resume normal activities when its over. These auras are happening more frequently.. I am writing to you because recently I have read articles in a medical newsletter warning that these symptoms could be a warning sign of stroke or heart attack. I showed the articles to both my cardiologist and ophthalmologist. Both said they had never heard of such a thing. Do you know anything about the migraine aura without the headache? Should I ignore these auras and not worry, or try to find a ...

A hybrid mass spectrometer comprises an ion mobility (IMS) section and a mass analysis section that analyses ions based on mass-to-charge ratios. In the IMS section, a DC potential gradient is established and a drift gas provided, so as to separate ions based on varying ion mobilities. Additionally, at least a downstream portion of the IMS section includes a rod set focusing ions along the axis, this prevents loss of ions and gives good transfer of ions into-a-mass analysis section, which can be a time-of-flight mass analyzer or an analyzer including a quadrupole rod set. A collision cell and mass analyzer can be provided between the two sections for MS/MS analysis. The IMS section then provides better utilization of an available sample; as each group of ions is elected from the IMS section, one ion can be mass selected as a precursor, for subsequent fragmentation/reaction and subsequent mass analysis of the product ions. Another aspect of the invention provides the ability to form potential wells,

I actually stopped all of my meds -- I used to take Midrin too, but ended up with rebound headaches all of the time. I tried acupuncture and it helped, but it got too expensive. I also reverted to plain old aspirin and alternating heat and cold on my forehead and the back of my neck. While it didnt completely resolve the headache, it made it bearable. The one thing I simply cannot deal with though is the nausea. When that sets in, I just have to go to bed and pull the covers over my head. Of course, with me being on Celebrex now for joint pain, I cant take the aspirin any more ...

The patients with subarachnoid haemorrhage in this study were selected because they showed secondary cererebral hypoxia/ischaemia of varying severity. Thus case 1 had a long lasting episode of secondary ischaemia leading to cerebral infarction in the microdialyisis probe area, cases 2 and 3 temporary secondary hypoxia/ischaemia without infarction in the probe area, and case 4 minor disturbances of energy metabolism and no structural changes in the frontal lobe harbouring the microdialyisis probe.The ischaemic event in case 1 was associated with a pronounced increase of D-glycerol. This probably reflected profound ischaemia with energy failure as the D-L/P ratio rise was large and accompanied by an undetectable D-glucose concentration and increased D-hypoxanthine and D-glutamate.15 This was supported by the occlusion of the right anterior cerebral artery diagnosed by a second angiography and the infarct development in the microdialyisis probe area according to CT and PET.15 In view of these ...

Interstitial fibrosis reduces the electrical coupling between cardiac myocytes because fibroblasts produce smaller or larger collagenous septa, which electrically insulate cardiac cells or muscle bundles. As a result, the normal myocardial architecture becomes disrupted and is transformed into a pathological substrate characterized by the presence of multiple insulating barriers, which force the depolarization wave to spread nonuniformly. As predicted by computer simulations and demonstrated in cell cultures, in such a medium, long local conduction delays occur that may slow the effective conduction velocity to very low values. Unlike a decrease of the rapid sodium current, which will result in conduction failure when conduction velocity is depressed to approximately 30% of control, slow conduction because of poor electrical coupling, although discontinuous, continues to proceed at very low effective conduction velocities.6-8 This is explained by the fact that, intrinsic to poor electrical ...

A system, method, or device classifies an arrhythmia according to the temporal order in which a depolarization wave associated with a particular heart contraction is received at a plurality of electrodes. One or more antiarrhythmia therapies is mapped to each arrhythmia classification. When a particularly classified arrhythmia is detected, the correspondingly mapped therapy list is selected and an appropriate antiarrhythmia therapy delivered. In one example, the particular therapy delivered in response to an arrhythmia depends at least in part on its historical success in treating arrhythmias of that classification.

Care coordination is a process that ensures a patients health services and information sharing preferences and needs are met. Care coordination, a critical component during the nations current shift from a fragmented system toward one that stresses accountability and continuity, is primarily accomplished by people as opposed to technology. This demands effective collaboration between the providers and organizations caring for each individual patient as opposed to service delivery from numerous providers.. In a new report, Laying a Foundation for Care Coordination: The Role of Health IT, the eHealth Initiative (EHI) describes ways public and private sectors can use health IT infrastructure to support care coordination. It also explores the functions and qualities required to achieve this vision.. The report presents a set of unified principles, which may be considered when implementing health IT to ensure it is effective in supporting care coordination. It also identifies four primary ...

BACKGROUND: Chronic heart failure (CHF) patients with elevated depression symptoms are at greater risk of morbidity and mortality. The mechanisms linking symptoms of depression with disease progression in CHF are unclear. However, research studies have found evidence of alterations in immune activity associated with depression symptoms that may influence heart function. The present study sought to determine the relationship between depression symptoms and chemotaxis of peripheral blood mononuclear cells (PBMCs) in CHF patients, both at rest and in response to moderate exercise. METHODS AND RESULTS: Sixty-five patients diagnosed with CHF (mean age, 59.8 +/- 14.5 years) and 45 non-CHF control subjects (mean age, 52.1 +/- 11.6) completed the Beck Depression Inventory (BDI) before undergoing a moderate 20-minute bicycle exercise task. Chemotaxis of PBMCs was examined in vitro to a bacterial peptide f-met leu phe (fMLP) and a physiologic chemokine, stromal cell derived factor-1 (SDF-1) immediately ...

News for Lombardia, Italy continually updated from thousands of sources on the web : Gucci Sales Boom But Wary of Potential Shift

I have close friends who get debilitating migraines so I knew a bit about auras, which are sensory disturbances that often precede migraine headaches. But experiencing one myself was still quite frightening.. It snuck up on me: I was happily reading a novel in bed when a spot on the page became blurry, even when I closed one eye. It quickly expanded in size, turning into a flickering, zig-zag pattern. After checking online and guessing that I probably had a migraine aura, I tried to go to sleep - and thats when it really got weird. Suddenly I saw the geometric pattern in color moving across my field of vision, even when I had my eyes closed.. Luckily, my aura lasted less than 30 minutes, so I was eventually able to go to sleep. I was also very happy to avoid the unbearable headache pain common in migraines. But my experience inspired me to learn more about auras.. According to Stanford neurologist Nada Hindiyeh, MD, about 30 percent of people that suffer from migraines get an aura before their ...

One third of migraine patients experience aura, i.e. dramatic, transient neurological symptoms, most often in the form of visual disturbances, that usually appear before the onset of migraine headache. The likely underlying mechanism of aura is known as cortical spreading depression, a wave of changes in electrical activity that slowly spreads in the outermost layer of the brain. It is currently not known what causes the aura to initiate in patients or what the relationship is between aura and migraine headache, e.g. if treatment targeted at aura mechanisms will prevent subsequent headache. Due to the short-lasting and unpredictable nature of aura, the only possible approach for systematic investigations is to experimentally trigger aura, but currently no method for aura-triggering is available.. The overall goal of the proposed project is to reveal the earliest mechanisms of the migraine attack by investigating the initiating factors of aura in the migraine brain.. Current animal evidence ...

In this work, a novel and extra sensitive method for on-line continues monitoring of Clarithromycin in whole blood sample was introduced based on coupling of electro-membrane extraction (EME) and stripping fast Fourier transform continuous cyclic voltammetry (SFFTCCV). In this method, the potential waveform was continuously applied on a Poly(L-Aspartic Acid)/Graphite Oxide/Pristine Graphene/Glassy Carbon Electrode and the electrode response was obtained by detracting the background current and in the following integrating the current in the specific potential range of oxidation of the analyte. This method was performed by applying a DC potential and migration of Clarithromycin from the sample solution into a layer of 4-methyl-2-pentanol that is immobilized in the pores of the sheet membrane and then migration into the acceptor solution. A low and valuable detection limit of 1.0 ng ml-1 and quantification limit of 6.0 ng ml-1 are considered as a part of the sensible results of this experiment.

Cerebral blood flow (CBF) is critical for the maintenance of cerebral function by guaranteed constant oxygen and glucose supply to brain. Collateral channels (CCs) are recruited to provide alternatives to CBF to ischemic regions once the primary vessel is occluded during ischemic stroke. However, the knowledge of the relationship between dynamic evolution of collateral flow and the distribution of regional blood flow remains limited. In this study, laser speckle imaging was used to assess dynamic changes of CCs and regional blood flow in a rat cortex with permanent middle cerebral artery occlusion (MCAo). We found that CCs immediately provided blood flow to ischemic territories after MCAo. More importantly, there were three kinds of dynamic changes of CCs during acute stroke: persistent CC, impermanent CC, and transient CC, respectively, related to different distributions of regional blood flow. Although there was the possible occurrence of peri-infarct depolarization (PID) during ischemia, ...

Semantic Scholar extracted view of Prolonged cortical silent period after transcranial magnetic stimulation in generalized epilepsy. by Roberto M Cantello

Silent migraine is an unusual name for a chronic illness. People are used to saying or hearing a scientific term when referring to a medical condition. Accordingly, the names of the different types of migraine give clue to its believed cause or source, or nature. Silent migraine, however , is a curious name because sound is not something associated that with migraine. Nevertheless, it is a disease that affects quite a number of people and for this reason, it needs to be understood. Silent migraine is also known as acephalgic migraine, eye migraine, visual migraine, ocular migraine. Experts, however , refer to it as migraine aura without headache. To better understand it, one needs to be familiar with the four stages of a typical migraine attack. The initial stage is called the prodrome. It is the time when warnings of an attack start to appear, such as irritability or confusion, diarrhea, thirst and food cravings. The next phase is the aura, a time when visual symptoms are felt. During this ...

The depolarization stimulus for the normal heartbeat originates in the sinoatrial (SA) node (Fig. 11-1), or sinus node, a collection of pacemaker cells. These cells fire spontaneously; that is, they exhibit automaticity. The first phase of cardiac electrical activation is the spread of the depolarization wave through the right and left atria, followed by atrial contraction. Next, the impulse stimulates pacemaker and specialized conduction tissues in the atrioventricular (AV) nodal and His-bundle areas; together, these two regions constitute the AV junction. The bundle of His bifurcates into two main branches, the right and left bundles, which rapidly transmit depolarization wavefronts to the right and left ventricular myocardium by way of Purkinje fibers. The main left bundle bifurcates into two primary subdivisions: a left anterior fascicle and a left posterior fascicle. The depolarization wavefronts then spread through the ventricular wall, from endocardium to epicardium, triggering ...

Aura Symptoms Highly Variable in Patients With Migraine What does migraine aura look like? And how do these visual manifestations differ between patients and in the same patient?These questions have intrigued neurologists for years, but getting clear-cut information has been difficult because most reports of migraine characteristics are retrospective - when asked, patients report details of their attack and how they felt after the fact.But now, researchers are delving deeper into the issue by using prospectively gathered reports and are turning up some surprising findings. For example, only about half of patients with migraine actually experience nausea, which is a main diagnostic symptom of migraine.From the 267 patient reports, the researchers collected data on 861 migraine attacks.The researchers found that the four most prevalent visual aura symptoms were: ...

Well, I am not a fan of Prednisone, but the side effects have been manageable for me. I started off at 100 mg. per day, which is a pretty high dose. Im now at 5 mg. per day every other day, and hoping to be completely off it soon. The most noticeable side effects that I experienced were manic behavior, sleeplessness and puffy feet and ankles.. I had so much energy that I didnt know what to do with myself. That has tapered off now that Im on a low dose, but for a while there I couldnt sleep, couldnt sit still, and found myself talking a mile a minute, sometimes to the cat. I still have somewhat swollen feet and ankles, but its much better. It was pretty pronounced when I was on the higher dose. Fluid retention is a common side effect.. Another thing I noticed was that I was getting migraine auras about 5 times a week. If you get migraine headaches you know what this is. If not, its a visual disturbance that happens before the headache - kind of like when you look out on the ocean on a very ...

Our world is in flux, constantly moving and changing faster than ever. Earth Moves: Shifts in Ceramic Art and Design seeks dynamic, contemporary ceramic works addressing creative responses to current shifts in the artists world and work. Ceramic artists are faced with new challenges and opportunities as technology affects their materials, equipment, studio practices and market. From commercial clay bodies and glazes to industrially designed decals and inclusion stains to computer interfaces with kilns; industry is impacting the studio potter in both subtle and dramatic ways. Some new technologies, such as rapid prototyping machines, CNC routers and 3D copiers are shifting the design and production of ceramic work into unfamiliar realms. Oxygen probes and computer controlled kilns affect glaze color through more scientifically oriented firings. Commercially designed stains and glazes reflect the latest trends in color and pattern sensibility. Less obvious, yet equally significant shifts occur ...

Machine elements operating under lubricated conditions will eventually fail due to high stresses and fatigue-related causes. In order to find optimum protective measures, it is important to understand how the stresses arise and what factors that influence their magnitude. With the current shift for more sever lubricating regimes, the role of tribo-improvers is becoming vital. At this point, the interplay between the chemisorption mechanism of various lubricant compounds and surface failure is not yet fully understood. To obtain a better understanding of this, a newly developed ionic structured tribo-improving additive, based on silicon, was investigated and benchmarked against conventional heavy-duty gearbox additives. A ball on disc device was operated under heavily loaded rolling/sliding conditions, at elevated temperature to simulate gear like conditions, and lubricating performance was subsequently evaluated in terms of friction and wear. Such results highlight the importance of properly ...

Functional MRI (fMRI) have provided information on networks, disorders, and cognitive performance of the brain. Recent studies have focused on fMRI during resting state (rs-fMRI) without any explicit tasks. To supplement BOLD signals, resting-state fMRI studies have been paired with simultaneous recording of electrophysiology data, a method to provide a direct measure of neural activity. Studies have focused on analyzing infraslow frequencies (,1Hz) to understand large-scale spontaneous spatial and temporal fluctuations. Dynamic analysis of infraslow frequencies has shown semi-reoccurring BOLD patterns, which have been defined as quasi-periodic patterns (QPP). This study expands on the previously acquired data using simultaneous fMRI and local field potential (LFP) recordings to understand effects of removing quasi-periodic patterns from the BOLD signal. Furthermore, this study focuses on the impact of quasi-periodic patterns regression on the relationship between BOLD and LFP at multiple ...

Designed for use with Warner imaging chambers with field stimulation electrodes, the SIU-102 features optical isolation at the input and transformer isolation at the output. Timing pulses can be controlled by any device capable of generating a TTL level positive pulse – a computer with data acquisition, for example. |br/| Positive or negative pulses, positive or negative DC, and bipolar pulses are possible in constant current or constant voltage delivery modes. For bipolar delivery, a positive pulse during the input pulse is followed immediately by a negative pulse of equal duration and amplitude. Bipolar pulse widths from 100 s to 100 seconds per each polarity are possible.

Why does the preferred CCT have a lower value than natural CCT? A possible reason for this effect is that observers prefer scenes that are more colorful, corresponding to a larger color gamut. This would be consistent with experiments in which the image quality is maximum when average chroma is higher than that obtained with natural illuminants (Fedorovskaya, De Ridder, & Blommaert, 1997). Figure 14a shows the pseudocolor map of the convex hull volume expressed in CIELAB space of the Munsell set rendered by the daylights tested. The volume has a maximum close to the average chromaticity for preference (open circle symbol). It also increases in the direction of negative DC, suggesting that scenes can look more colorful or vivid with these purplish daylights. This result obtained with the Munsell set also holds for the group of scenes tested. The color volume map of each scene was normalized, and the result was averaged across all scenes tested. The CCT producing the maximum chromatic volume of ...

A friend once remarked I was a wonderful role model for how to live a great life despite suffering from depression. At the time, I was unable to see the value in that since, the ultimate goal is to be depression free - isnt it? Suffering from depression means were flawed, right? It means theres something wrong with my life in which case, what is there to be proud of?. After several trips out of depression and then descending into the pit of despair over and over again I began to wonder whether or not Id ever be completely free of depression and, more importantly, whether or not it really matters.. Nowadays Im able to see that:. ~ Suffering or not suffering from depression is not whats important ~ How I respond to what occurs in my life (including depression) is. Given that 75% of depression sufferers cycle back into depression at some point, it makes more sense to learn to enjoy your life despite depression rather than endlessly waiting for this wonderful time when you will never be ...
