Transduction of the contralateral ear after adenovirus-mediated cochlear gene transfer. (1/8)

Cochlear gene transfer is a promising new approach for inner ear therapy. Previous studies have demonstrated hair cell protection with cochlear gene transfer not only in the inoculated, but also in the uninoculated ear. To characterize the kinetics of viral spread, we investigated the extent of transgene expression in the contralateral (uninoculated) cochlea after unilateral adenoviral cochlear gene transfer. We used a lacZ reporter gene vector, and demonstrated spread of the adenovirus into the cerebrospinal fluid (CSF) after cochlear inoculation of 25 microl viral vector. Direct virus application into the CSF resulted in transduction of both cochleae, whereas virus inoculation into the bloodstream did not. The cochlear aqueduct was identified as the most likely route of virus spread to the contralateral cochlea. These data enhance our understanding of the kinetics of virus-mediated transgene expression in the inner ear, and assist in the development of clinical applications for inner ear gene therapy. Our results showed a functional communication between the CSF and the perilymphatic space of the inner ear, that is not only of importance for otological gene transfer, but also for CNS gene transfer.

MR cisternography of the cerebellopontine angle: comparison of three-dimensional fast asymmetrical spin-echo and three-dimensional constructive interference in the steady-state sequences. (2/8)

BACKGROUND AND PURPOSE: MR cisternography has been used as the noninvasive screening tool of the cerebellopontine angle. The purpose of this study was to directly compare two currently dominant types of sequences for heavily T2-weighted MR cisternography. METHODS: Three-dimensional fast asymmetric spin-echo (3D-FASE) sequences, which are 3D half-Fourier rapid acquisition with relaxation enhancement and 3D constructive interference in the steady-state (3D-CISS) sequences, were compared on a clinical 1.5-T MR unit using the same scan times. In five healthy volunteers, the contrast-to-noise ratio (C/N) between CSF and the cerebellum was measured at three locations. Then, for qualitative analysis, the quality of the labyrinth was scored on the original source multiplanar reformatted images, the virtual endoscopic images, and the maximum intensity projection (MIP) images. In 20 consecutive patients with suspected cerebellopontine angle tumors, visualization of the tumors was evaluated using 3D contrast-enhanced spoiled gradient-echo imaging as the standard of reference. RESULTS: Both sequences showed comparable mean C/N values; however, in qualitative analysis, the scores for 3D-CISS on the source, virtual endoscopic, and MIP images were significantly lower than those on the images obtained with 3D-FASE, owing to more prominent flow and magnetic susceptibility artifacts on the 3D-CISS sequences. In all subjects, discontinuity of the semicircular canals was seen on the virtual endoscopic and MIP images obtained with 3D-CISS, owing to susceptibility artifacts, but not on those obtained with 3D-FASE. All 12 tumors were detected by both sequences, but 3D-CISS gave one false-positive result. CONCLUSION: 3D-FASE is considered the method of choice because artifacts are reduced and specificity is increased.  (+info)

Persistence of perilymph fistula mechanism in a completely paretic posterior semicircular canal. (3/8)

The three dimensional eye movements (search coil technique) of a patient with a completely paretic left posterior semicircular canal as a result of a perilymph fistula (PLF) were studied. The patient still exhibited pressure induced nystagmus that obeyed Ewald's first law. This finding cannot be explained by otolith stimulation, but might indicate that PLF mechanisms either persist in canal plugging or act on the ampulla by directly deflecting the cupula.  (+info)

Cochlear aqueduct flow resistance depends on round window membrane position in guinea pigs. (4/8)

The resistance for fluid flow of the cochlear aqueduct was measured in guinea pigs for different positions of the round window membrane. These different positions were obtained by applying different constant pressures to the middle ear cavity. Fluid flow through the aqueduct was induced by small pressure steps superimposed on these constant pressures. It was found that the resistance for fluid flow through the aqueduct depended on the round window position but not on flow direction. The results can be explained by special fibrous structures that connect the round window with the entrance of the aqueduct. It was also found that the equilibrium inner ear pressure depends on middle ear pressure, indicating that the aqueduct does not connect the inner ear with a cavity with constant pressure.  (+info)

How does the urodele ear develop? (6/8)

An overview is provided of the structural and molecular events causing the transformation of undifferentiated epidermal cells together with the underlying mesenchyme to become the complex, three-dimensional ear. While tremendous progress has been achieved in a few model systems, enough is not yet known about the comparative embryology of ear development to provide causal explanations of the adult structural differences among species. It is hoped that the changes in selector and/or structural genes, as well as changes in the spatiotemporal induction of structural gene activation, and possible changes in the interaction between the various embryonic sources which contribute to the ear, will soon be understood. The most promising new avenue for research appears to be studies which combine classical transplantation tissue experiments with modern gene expression analyses and modern in vitro assays of the role of putative morphogens or trophic factors. It is emphasized that it is not understood what is missing in the developmental program of those salamanders which have lost a basilar papilla. Direct comparison of gene expression patterns and xenoplastic transplantations in salamanders of comparable stages which either do or do not develop this organ should help to clarify the molecular events that have led to this major evolutionary novel feature of the vertebrate ear.  (+info)

Enlarged cochlear aqueduct. (7/8)

Enlargement of the cochlear aqueduct is a controversial topic, with experienced investigators doubting its existence because of a lack of published cases. We describe the CT appearance of an enlarged cochlear aqueduct in a patient with advanced congenital inner ear anomalies and congenital hearing loss. The intent of this article is to present the CT appearance of a presumably enlarged cochlear aqueduct and to underscore the need to examine this structure in patients with congenital hearing loss.  (+info)

Sudden hearing loss: frequency of abnormal findings on contrast-enhanced MR studies. (8/8)

BACKGROUND AND PURPOSE: Our purpose was to determine the frequency of abnormal findings on contrast-enhanced high-resolution MR imaging studies in patients with sudden hearing loss. METHODS: Seventy-eight consecutive patients with sudden hearing loss underwent contrast-enhanced MR imaging of the temporal bone, cerebellopontine angle, and brain. Additional tests included audiologic examination, electrocochleography, fistula tests, and serologic tests for viral agents and autoimmune disorders. RESULTS: Probable causes of the sudden hearing loss in these patients included viral or immune-mediated disease, Meniere disease, vascular disorder, syphilis, neoplasm, multiple sclerosis, and perilymphatic fistula. Twenty-four (31%) of the 78 patients were found to have abnormal imaging results early in the course of their work up and treatment. CONCLUSION: The prevalence of abnormal findings on contrast-enhanced MR studies is higher than previously reported in patients with sudden hearing loss.  (+info)

Definitions of sudden hearing loss have been based on severity, time course, audiometric criteria, and frequency spectrum of the loss. Abrupt as well as rapidly progressive losses have been included under a single definition of sudden hearing loss.
Intracranial fluid pressure is measured as a function of a characteristic or characteristics of an eardrum. Either or both of the displacement of the eardrum when the stapedius muscle is stimulated or the aural acoustic compliance of the eardrum is measured and provided the cochlear aqueduct is open this will give an indication of intracranial fluid pressure without surgery. Acoustic compliance is measured under conditions of tympanometry but the tympanometry facility is disabled during displacement measurement. The data obtained by the method of the invention may be compared with reference data obtained from the same patient or in clinical trials to provide a real-time record of intracranial fluid pressure changes. Preferably eardrum displacement is used as a baseline measure and acoustic compliance measurement records short-term variation, the two records being combined by computer. Reference data may be input to the computer to update the information displayed. This reference data may include known

The standard of care treatment of sudden hearing loss uses a type of steroid called glucocorticoid. Examples of glucocorticoids are prednisone, methylprednisolone and dexamethasone. Not everybody recovers hearing with glucocorticoid treatment. Fludrocortisone is a different type of steroid called mineralocorticoid. Unlike glucocorticoids, which work by reducing inflammation, mineralocorticoids work by changing salt and fluid balance. In animal studies, fludrocortisone is at least as effective as glucocorticoid in preserving hearing. Fludrocortisone is not approved for the treatment of sudden hearing loss.

Sudden hearing loss is a rapid loss of hearing in one or both ears which can happen to an individual all at once or over a period of up to 3 days. Usually, patients report that their ear feels full or blocked. Dr. Stachler notes that as symptoms of sudden hearing loss are so prevalent and non-specific, evaluation and treatment are often delayed in several cases. Sudden hearing loss can be caused by a range of issues, such as infectious diseases, induced hearing loss, head trauma, noise induced hearing loss, Menieres disease, and circulatory problems.. The new guideline, which is intended for all clinicians who see patients aged 18+, includes:. ...

Many posters including yours truly, have discussed the Big A versus Belmont Park developments for some time now. Former Governor Spitzer convinced a majority of Albany back in March-April of 2007, that a "friendly" deal with the NYRA, lets call it "The Land Grab" in conjunction with the closure and sale of of the land at Aqueduct, with the grand development at Belmont Park was the way to maximize benefit to the state. The NYRA hasnt ever had any real qualms about not having to race in the freezing cold at Aqueduct, knowing some provision for a shorter late fall-early spring meet would be made at Belmont. An astute political move was to make it look like Delaware North was going to pay a ton of money to develop the Big A, then when they defaulted or tried to modify the deal, the discussion of just doing one grand palace at a downstate racetrack could gain some momentum once again, and as a last ditch concession to the Aqueduct community if necessary, bring in a vendor to hang some machines on ...
I love my job as a first grade teacher. In thirty seconds my life changed when I had a headache that was unbelievable. Two days later, I found out that I had a sudden hearing loss in the right ear and then the ringing. That loud, annoying ringing in my ears was so hard to take. The doctor put me on steroids and then told me to live with the ringing. I couldnt stand it. My audiologist decided to give me a list of someone who is a specialist in tinnitus. That was when I went to Dr. Paula Schwartz and she recommended Neuromonics Tinnitus Treatment. I had to do something and after nine months of using Neuromonics, I got my life back and loving my job even more. I find it easier to concentrate at my job and can sleep through the night. I have control of tinnitus and it does not have control of me ...
Lately I have been enjoying creating a lot more gardens which use less water. When I work in Los Feliz, I often drive on Franklin Ave and turn ono Riverside Drive to get to the 5 South freeway. Each time I drove through this intersection the newly planted garden on the corner caught my eye. I decided to stop and take a look and discovered a lovely water-wise garden installed by the LADWP called the Aqueduct Centennial Garden. I soon found more info about this garden on-line.. August 12, 2013 - (Modified Press Release). LOS ANGELES - Los Angeles City Councilmember Tom LaBonge of the 4th District, James McDaniel, Senior Assistant General Manager, Water System at the Los Angeles Department of Water and Power (LADWP), and community members convened at the recently-renovated Mulholland Memorial Fountain in Los Feliz to break ground on the new Los Angeles Aqueduct Centennial Garden.

The first step that your veterinarian will take in order to determine what is causing your dogs illness will be to perform basic bloodwork and possibly a urinalysis or x-rays. Abnormal findings on a Complete Blood Count (CBC) usually include low numbers of platelets, red blood cells (anemia), and abnormal white blood cell counts. In early stages, the white blood cell count will be low, but in later stages of disease, the white cell count may be increased. In addition, biochemical tests will often show low protein levels, abnormal calcium levels, electrolyte abnormalities, and abnormal liver or kidney values ...
Primary pulmonary neoplasms have been reported to occur predominantly in dogs over seven to eight years of age. The results of this study support this finding. No sex or breed predisposition to primary lung tumors have been identified. In this study, males and females were represented equally. Although no one breed was affected more frequently than others in this study, all of the dogs were medium to large size breeds with the exception of case #3. Further case studies were necessary to determine if this is either a significant trend or because of the predominance of medium to large breed dogs within our referral population.. Clinical signs associated with primary pulmonary neoplasia are often vague and nonspecific. It has been reported that as many as 33 percent of primary lung tumors are discovered during a physical or radiographic evaluation for another problem. There were no abnormal findings on physical examination in four of the 14 dogs (29 percent) in this study.. The most common clinical ...
In 2067, human cloning is a part of everyday life. But it is a bizarre form of cloning: not actually the direct copying of a humans, but rather the construction of custom-made reproductions of humans using animal DNA. The CIA uses these so-called "chimeras" for various undercover operations, and one of their technicians, Simon Boyle, has a sideline making illegal copies: chimeras based on famous criminals, for rent. His Billy the Kid, a creation unable to comprehend or sometimes even recognize the sorts of things that didnt exist before the 1880s and endowed with powerful sex pheromones, is quite popular for a night of historically convincing passion with rich women, particularly the part where Boyle (as sheriff Pat Garrett) guns him down. As the story progresses, Billy the Kid starts remembering things from his previous lives. One of Boyles clients sets Billy loose into the mean streets of the 21st century, where he struggles to seize control of the myths in his ROM. Jane, a worker in a ...

Leptomeningeal carcinomatosis is a rare entity caused by metastases from solid tumors in the form of diffuse seeding to the leptomeninges. Lots of neurologic symptoms related to cerebrum, cerebellum, spinal root, and cranial nerves can be occurred in leptomeningeal carcinomatosis patients. It is not often that only bilateral hearing loss is present as the initial clinical symptom. In this report, we present a 54-year-old man represented with sudden bilateral hearing loss and vertigo who were operated for duodenal adenocarcinoma six months before. The clinical, radiologic, and cerebrospinal fluid cytologic features of the patient and the case reports of sudden hearing loss related to leptomeningeal carcinomatosis are discussed. ...

A study using Taiwanese medical insurance records suggests sudden loss of hearing might be an early sign of vulnerability to stroke, researchers say. Hearing loss can foreshadow a cerebrovascular event by as much as two years, the study published in Stroke: Journal of the American Heart Association found. Lead investigator Herng-Ching Lin, a professor at Taipei Medical University School of Health Care Administration, says five-year follow-up data on 1,423 patients hospitalized for an acute episode of sudden sensorineural hearing loss showed they were more than 1 1/2 times more likely to suffer a stroke than a control group of 5,692 patients who had been hospitalized for an appendectomy. However, because insurance records may not have contained reliable information, such as correct diagnostic codes or other factors, the findings should be considered tentative, Lin says. To the best of our knowledge, no study has investigated the incidence or risk of cerebrovascular diseases developing following ...
As this case report demonstrates, there is only a partial and transient beneficial effect of ERT and hyperbaric oxygen treatment combined with corticotherapy and pentoxifylline for hearing loss in patients with FD. As there is no international consensus on treatment of SHL [12] (particularly in patients with FD), the administered therapy is the standard therapy for SHL, and the results obtained in our case were at their best for the first treatment course, whereas partial regression of the symptoms occurred on the second occasion. Although SHL in patients with FD is rarely described, the symptoms are consistent with the vascular alterations caused by the disease in other areas. The incidence of SHL may be underestimated.. The mechanism of progressive SHL in patients with FD remains unclear. It has been suggested that globotriaosylceramide accumulation in vascular endothelium, decreased numbers of spiral ganglion cells [13], long-term obstruction of cranial vessels by dolicho-ectasic arteries ...

Sudden hearing loss is not a common occurrence, but more often it develops gradually, till the patient fails to notice that they are missing out subtle everyday sounds such as a ticking clock or a rustling newspaper, currency etc. By the time its moderate to severe, the patient finds its difficult to comprehend or follow speech which is often noticed by the patients family members and close aids, who had to repeat to make them heard.. ...
The other take-home message from your friends experience is to get an evaluation from an otolaryngologist ("Ear, Nose and Throat" doc-but if you put it in Greek or Latin we feel more special) for any sudden hearing loss. Sad to say, we see many that are misdiagnosed for months as "allergies" or "fluid." And its sometimes tough to have to say to a patient, "we might have been able to do something about your hearing if we could have seem you in the first week or two." Tumors causing hearing loss are rare, but Ive diagnosed about 10 of them in the last 15 years. Fortunately, they are usually benign and slow growing--but in a lousy spot. They are somewhat related to neurofibromatosis II, but thats even rarer (and familial ...
Results PAPS patients had higher frequency of at least 1 abnormal finding on videocapillaroscopy (77% vs 12%, p,0.009, OR=23, 95% CI=4-132), higher frequency of enlarged capillaries (69% vs 0%, p=0.0001, OR=33, 95% CI=3.8-295), lower frequency of "perfect normal" pattern (11.5% vs 56%, p=0.004, OR=0.1, 95% CI=0.02-0.48) than controls, and 8 patients (31%) showed changes compatible with the "early" SSc Cutolo pattern (,4 dilated capillaries/mm, ,4 haemorrhages/mm, preserved architecture and no avascular areas). In PAPS patients, capillary haemorrhages were associated to neurologic manifestations (75% vs 14%, p=0.02, OR=19, 95% CI=1.4-248) and to comorbidity with hypertension (75% vs 14%, p=0.02, OR=19, 95% CI=1.4-248). ...

Which is to say, Flaubert saw himself as encompassing all that there is. And not only that: he feels he is in danger of having his knowledge of life, the world, and the ages of history, compromised by contact with the world: this is the reason he needs to live in isolation to serve his art. & so in another letter, he characterizes himself as a man of wax; everything gets imprinted on him [he is speaking of himself i the third person], is encrusted on him, penetrates him. If I should visit you, I should think of nothing but you and yours, your house, your country, the appearance of the people I had met, etc. In a related vein, a few weeks later he casually writes, I must not give myself a week of holiday; that is why I do not go to Nohant [to visit Sand].

The aim of this paper is to present the evolution of aqueduct technologies through the millennia, from prehistoric to medieval times. These hydraulic works were used by several civilizations to collect water from springs and to transport it to settlements, sanctuaries and other targets. Several civilizations, in China and the Americas, developed water transport systems independently, and brought these to high levels of sophistication. For the Mediterranean civilizations, one of the salient characteristics of cultural development, since the Minoan Era (ca. 3200-1100 BC), is the architectural and hydraulic function of aqueducts used for the water supply in palaces and other settlements. The Minoan hydrologists and engineers were aware of some of the basic principles of water sciences and the construction and operation of aqueducts. These technologies were further developed by subsequent civilizations. Advanced aqueducts were constructed by the Hellenes and, especially, by the Romans, who dramatically
In cases where the pulsating or beating noise can be heard by your doctor during examination, the cause may be linked to a bruit. A bruit is an abnormal sound of arterial blood flow usually heard by the sufferer or during auscultation (using a stethoscope) by the examining physician. A bruit is usually associated with vascular disorders like atherosclerosis, aneurysm, thromboembolism or certain physical abnormalities of the arteries or veins.. A bruit is a verifiable sign of a specific vascular disorder or abnormality and should not be confused with the symptom of a ringing sound in the ear associated with tinnitus.. Common complaints from tinnitus sufferers is that the ringing in the ears affects sleep, concentration when focusing on reading, studying or other mental activities and communication with others during a conversation. However some of these complaints may be due to associated hearing loss that accompanies many cases of tinnitus. Also refer to sudden hearing loss.. ...
Fluid present in middle ears is observed during the regular treatment of patients.. The observation in made during the treatment and not as an additional activity. The fluid is either a steroids solution or sterile normal saline or ears mucus discharge, all in perforated eardrums, either as a part of their intra-tympanic treatment for sudden hearing loss, or traumatic perforation [considered as the normal ears] compared to otitis media ears.. The observation is made on bubble formation over the perforation. The time length of the inspection is about 1 minute, under the microscope, during the treatment. ...
Background: Sudden cardiac arrest in a young healthy athlete is a rare but catastrophic event. Current American Heart Association preparticipation screening (AHA PPS) guidelines recommend a focused history and physical without routine imaging or ECG screening. We propose that a focused echocardiogram is a useful modality to identify structural abnormalities that may lead to sudden cardiac arrest or other cardiovascular events in athletes.. Methods: We performed a focused 5 minute echocardiogram on all incoming varsity Division I collegiate athletes at the University of Wisconsin from 2005 to 2013. The echocardiograms were performed on the same day as their routine AHA-based PPS exam. Abnormal findings on a focused echocardiogram prompted further testing for confirmation. In this investigation, we report the prevalence of abnormal findings in these athletes.. Results: Of the 2898 athletes screened, 1484 (51.2%) were female. The average age was 18.8 years. The majority (98.3%) of athletes had ...
An MRI scan is the best way to locate multiple sclerosis (MS) lesions (also called plaques) in the brain or spinal cord. An MRI scan is abnormal in more than 95% of people recently diagnosed with MS.footnote 1. But abnormal MRI results do not always mean that you have MS. Abnormalities show up on scans from many illnesses other than MS. An abnormal finding on an MRI scan alone is not enough to diagnose MS. Your doctor will confirm a diagnosis of MS based on your symptoms, your neurological exam, and the results from an MRI and other tests.. When abnormal MRI results occur along with a medical history, abnormal nervous system exam, and other test results that are typical of MS, it is very likely that you have MS.. If you have already been diagnosed with MS, MRI scans can sometimes distinguish new lesions from older ones and can help your doctor(s) follow the progress of the disease. Continuing to have periodic MRI scans if you have relapsing-remitting MS may help identify new lesions even when ...
I also had the luxury of having Haruki Murakamis 1Q84 read to me. I loved that novels premise- that it is possible to enter another world by listening to Janáčeks Sinfonietta then climbing down a staircase that juts from a busy freeway offramp in Tokyo. And that one knows that one it in that world because there are two moons, the second of which is small and moss-coloured. Originally published in Japan in in 2009 and 2010 in three volumes, 1Q84 also tackles some weighty issues- secret cults, serial murder, domestic abuse, and literary fraud. I very much enjoyed Murakamis ability to take us from the ordinary to the subtly unfamiliar and then to plunge us from the subtly unfamiliar into the profoundly weird. He does it with such a deft hand one doesnt even realize it is happening, until small beings emerge from the mouth of a sleeping girl and you just nod and think, "okay." (Some critics hated Murakamis "little people," but they worked for me, and I appreciated the risk.) Im always ...

Sudden hearing loss secondary to an acute cochlear hemorrhage is rare. Estimates of annual incidence of sudden hearing loss are 5-20 per 100,000 of which only a small percentage is due to intralabyrinthine hemorrhage. Only 1-4% of all cases of sudden sensorineural hearing loss are bilateral. The fact that this patient has Down syndrome is significant, since hearing loss has been reported in both acute and chronic myeloid leukemias, which occurs at a higher frequency in Down patients. One theory proposes that hyperleukocytosis causes leukostasis with abnormal microvascular perfusion. The cochlea is an end organ in terms of its blood supply with no collaterals. It is supplied by the labyrinthine artery, a branch of AICA. Its tortuous course predisposes it to the effects of hyperviscocity. In addition, it is extremely sensitive to changes in blood supply. Thus, the time course of hearing loss correlates well with a vascular event such that an acute hearing loss is most likely caused by hemorrhage, ...

MATERIALS AND METHODS: We retrospectively reviewed 112 consecutive patients (224 ears) with vestibulocochlear symptoms who underwent concurrent MR imaging and CT of the temporal bones between 2007 and 2009. MR imaging protocol included a FIESTA sequence covering the temporal bone (axial 0.8-mm section thickness, 0.4-mm spacing, coronal/oblique reformations; 41 patients at 1.5T, 71 patients at 3T). CT was performed on a 64-row multidetector row scanner (0.625-mm axial acquisition, with coronal/oblique reformations). Both ears of each patient were evaluated for dehiscence of the superior and posterior semicircular canals in consensual fashion by 2 neuroradiologists. Analysis of the FIESTA sequence and reformations was performed first for the MR imaging evaluation. CT evaluation was performed at least 2 weeks after the MR imaging review, resulting in a blinded comparison of CT with MR imaging. CT was used as the reference standard to evaluate the MR imaging results.. ...
Like I said the biological world are full of majins; all interconnected to one another in the strangest of ways. Autoimmunity is a subject that thrills me. For those of you are unfamiliar to the concept, its quite simply put. Its when your immune system- that which guards you from bacteria, viruses and worms- loses its ability to distinguish friend from foe and goes on a wild rampage attacking the body cells and causing tissue damage in the long run. Imagine a situation of friendly fire and you get the idea.Examples range from multiple sclerosis, systemic lupus, Graves Disease and Type I diabetes. So to give you a very, very general outline, its like this: there are two types of cells called the B and T cells which mature in the bone marrow and the thymus respectively. The T-cells can potentially detect millions of different antigens , but they need help. Cells called dendritic cells (a part of the antigen-presenting cell milleu) can process antigens and "present" them to the T-cells for ...
Coetzees finding an ideal of human dignity in the defiant self-pity that Kundera would call litost is particularly sinister under these circumstances. Because what Bucky has been deprived of, leading him to insist that Marcia cannot possibly know her own mind when she insists she still wants to marry him, is his old life as a strong, able-bodied authority figure in a sunny homosocial environment. The novels final scene is a flashback to Buckys demonstrating his skill with the javelin to the schoolchildren under his care: its a celebration of primal muscularity worthy of Leni Riefenstahl, and Arnie (with the verbal awkwardness Roth gives him whenever he reaches for the sublime) quite explicitly recalls the event as a masculine ritual: "Through him, we boys had left the little story of the neighborhood and entered the historical saga of our ancient gender." The scene perfectly illustrates the ideal in the face of which disability is incompatible with potency, community, and masculinity. It ...
That is hard.

The cerebrospinal fluid flow in the third ventricle of the brain and the aqueduct of Sylvius was studied using computational fluid dynamics (CFD) based on subject-specific boundary conditions derived from magnetic resonance imaging (MRI) scans. The flow domain geometry was reconstructed from anatomical MRI scans by manual image segmentation. The movement of the domain boundary was derived from MRI brain motion scans. Velocimetric MRI scans were used to reconstruct the velocity field at the inferior end of the aqueduct of Sylvius based on the theory of pulsatile flow in pipes. A constant pressure boundary condition was assigned at the foramina of Monro. Three main flow features were observed: a fluid jet emerging from the aqueduct of Sylvius, a moderately mobile recirculation zone above the jet and a mobile recirculation below the jet. The flow in the entire domain was laminar with a maximum Reynolds number of 340 in the aqueduct. The findings demonstrate that by combining MRI scans and CFD ...
Sudden hearing loss occurs through an infection, a trauma, changes in atmospheric pressure, or earwax buildup or impaction. Some cases are reversible with care and treatment.. Gradual hearing loss, called presbycusis, is a culmination of many factors such as environment, drugs, and disease. We cannot reverse gradual hearing loss, but we can take steps to prevent or stop further loss.. Causes of Hearing Loss. Heredity and chronic exposure to loud noise are two contributors to gradual loss in adults. You cannot change your ancestors, but you can change or control your environment. Other, less common, causes are disease or illness from a virus or bacteria, heart condition or stroke. Head injuries and tumors could also be a cause. Side effects from medication, like chemotherapy drugs and some antibiotics, may also bring about hearing loss. Temporary hearing loss can happen if you take high doses of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), antimalarial drugs or loop diuretics.. Noise ...

Variations in the size and shape of the human vestibular aqueduct were evaluated in 118 plastic casts of unselected specimens of human temporal bones. They were examined by conventional radiography and by high resolution CT. The degree of the mastoid and perilabyrinthine pneumatization was defined and classified into 3 types. The dimensions of the peripheral portion of the aqueduct were found to be related to the extent of the perilabyrinthine pneumatization.. ...
MEAHS TO INDUCE CRIMINAL MISCARRIAGE 33T iot often produce the desired effect. On the other hand, the slightest violence, such as the slipping of a foot, the fright of a cat or a dog or even the sudden hearing of a noise, may cause miscarriage, especially in a woman who is predisposed to abort. A woman 7 who was three months pregnant, was awakened by the noise of a eol- Lision of a motor car with the wall of her house and aborted the next day. She and her husband sued the motorist for damages. The doctor who attended the woman was clearly of opinion that the shock resulting from hearing a noise was enough to cause a miscarriage. The jury found a verdict for the plaintiffs. The husband recovered "what he had paid on his wifes behalf and the wife was awarded 175. Occasionally women are murdered to avoid further worry and disgrace. On the 14th January 1911, the body of a Hindu female, about 30 years old, was brought to the Agra Medical School Mortuary with a police report that she was found in a ...
Its very possible that the gold rail we saw yesterday will carry over into todays card, but Im just not the type of handicapper who likes to analyze races assuming a bias will be present. Its useful to know when surfaces have become biased and keep detailed records of such occurrences, but making money by just blindly betting inside speeds is not what draws me to this game.. Im assuming that many horseplayers will enter this card having handicapped for the bias and will therefore gravitate towards the probable inside speed Alice and Trixie in this race. On a fair racetrack, I would not like Alice and Trixie at all. She proved on January 17th that she wants no part of a route of ground as she stopped to walk in the final furlong against a field that may have been even weaker than the one she meets today. In all likelihood Alice and Trixe is going to be an odds-on favorite here as many will assume that she will play out to be the inside speed. That may very well be the case, but I dont see ...
A tissue stimulation method which uses wave-guiding principles to construct a focused point of stimulation at any location within a region of electrically excitable living tissue. The excitation is formed through the constructive interference of different frequency wave energies, traveling at frequency-dependent velocities, which coalesce at the stimulation point. Further energy is brought to the stimulation point through reflection(s) at the boundaries of the wave-guiding structure. The resulting excitation signal depends upon several factors, including pulse envelope and duration, allowable frequency range, and stimulation time.

These Hearing Aid Sweatbands eliminate sudden hearing loss caused by rain, snow or perspiration, and stops dust infiltration. The specially designed fabric is both moisture repellent and moisture absorbent, while not inhibiting sound. Virtually any BTE hearing aid user can benefit. Natural colored. Two sweatbands per pack. Hand wash and air dry for best results.Allows moisture to evaporate and wick away. Doesnt hold moisture against the hearing aid. Protects the BTE hearing aid from hair styling products if worn to a hair salon.
Changes in air pressure that occur in the middle ear such as when your ears pop normally have no effect on your inner ear. However, if a fistula exists, changes in middle ear pressure may directly impact the inner ear, causing unwanted symptoms as the balance and inner ear structures are stimulated unnecessarily by the leaking perilymph fluid in the ear. This is why many people with this condition find that their symptoms exacerbate with coughing, sneezing, or blowing their nose. An increase in physical activities may have the same effect since unsteadiness tends to increases with physical exertion and decrease with rest ...
An infertility ultrasound is an important first test for any women experiencing difficulty conceiving. First, an infertility ultrasound will verify that the uterus and both ovaries are present. Ultrasound does not reliably detect the fallopian tubes. for this evaluation a hysterosalpinogram is performed. The size, shape and position of the uterus are recorded. Masses within the uterus called fibroids can measured and mapped. The ovaries can also be measured. The size of the ovaries as well as the number of follicles present are an important determinant of a womans ovarian reserve .. A common abnormal finding on an infertility ultrasound is ovarian cysts. Most often, ovarian cysts are simply evidence of a growing egg or evidence of recent ovulation. On occasion, however, a cyst may represent an abnormality such as endometriosis .. Finally, although normal fallopian tubes are usually not seen on an infertility ultrasound, a type of abnormal fallopian can be seen. Occasionally, if the distal end ...
The clinical and pathological (imaging, neurocognitive assessment, CSF analyses) evolution of the present patient with fetal onset hydrocephalus supports the possibility that the progressive stenosis of SA initiated during the embryonic period may have resulted from (1) ependymal disruption of the cerebral aqueduct and/or (2) dysfunction of the subcommissural organ.. A strong body of evidence obtained in mutant hydrocephalic animals and human hydrocephalus indicates that the loss of neural stem cells/ependyma from the embryonic germinal zone, regarded as ventricular zone disruption, is associated with the onset of hydrocephalus [5-12]. The disruption phenomenon is the final outcome of several genetic and non-genetic abnormalities that lead to the abnormal expression of gap and adherent junctions [11, 12, 37-39]. In mutant hyh mice, the time program of ventricular zone disruption starts during fetal life and ends by the end of the first postnatal week [5-7]. It is only after this disruption ...

still in existence after continuous use of over 2,000 years. The best preserved Greek aqueduct is the one still in use at Syracuse. The most famous Roman aqueducts were the Aqua Apia, 10 miles in length; the Aqua Martia, 60 miles; the Aqua Julia, 15 miles, and the Aqua Claudia, 46 miles. With the exception of the Claudia, all these were constructed before the birth of Christ. Among the most important aqueducts in the United States are the following: The old Croton, New York City, built 1837-42, length, 38 1/4 miles, capacity, 100 million gallons daily. The new Croton, built 1884-90, length 30 1/2 miles, capacity, 250 million gallons daily. Washington Aqueduct, built 1852-59, two 4-foot pipes. Boston, from Sudbury River, built 1875-78, length, 16 miles. Baltimore, from Gunpowder River, built 1875-81, length, 7 miles. The Sutro tunnel, 4 miles long, constructed to drain the Comstock Lode, Nevada, at a depth of 1,600 feet. It was chartered February 4, 1865, and completed June 30, ...
The project stretches more than 700 miles, from Lake Oroville in the north to Lake Perris in the south. Water is stored at Lake Oroville and released when needed into the Feather River, which flows into the Sacramento River and to the Sacramento-San Joaquin River Delta. In the north Bay-Delta, water is pumped into the North Bay Aqueduct for delivery to Napa and Solano counties. In the south Bay-Delta, SWP pumps lift water into the 444-mile-long California Aqueduct. Some water flows into the South Bay Aqueduct, to serve areas in Alameda and Santa Clara counties. The remainder flows southward to cities and farms in central and southern California. In the winter, when demands are lower, water is stored at the San Luis Reservoir located south of the Bay-Delta. The SWP terminates at Lake Perris where it joins MWDs system..

DFNB4 with enlarged vestibular aqueduct is characterized by pre- or perilingual onset of sensorineural or mixed hearing loss, which may be fluctuating or progressive. The hearing loss is associated with temporal bone abnormalities, most commonly enlargement of the vestibular aqueduct, but it can also include the more severe Mondini dysplasia, a complex malformation in which the normal cochlear spiral of 2.5 turns is replaced by a hypoplastic coil of 1.5 turns (summary by Campbell et al., 2001 and Pryor et al., 2005). Enlarged vestibular aqueduct is the most common form of inner ear abnormality and can be associated with disequilibrium symptoms in a minority of patients (Valvassori, 1983; Jackler and de la Cruz, 1989; Levenson et al., 1989; Arcand et al., 1991; Belenky et al., 1993; Okumura et al., 1995).

NEW SCAN ALMOST 100% ACCURATE IN IDENTIFYING BREAST CANCER. An estimated 1.4 million women undergo breast biopsies every year in the United States for abnormal findings on their mammograms, and approximately 85 percent of these suspicious mammographic findings will turn out to be benign following biopsy.. At the present time, breast imaging technology has not advanced enough to replace biopsy for most women with suspicious abnormalities noted on mammograms, or for women who develop palpable breast lumps. For example, MRI scans can detect 95 to 98 percent of early breast cancers, but MRI is also associated with a very high "false-positive" rate, in which as many as 25 percent of identified abnormalities turn out, after biopsy, to be benign. In an ideal world, a "perfect" breast scan would accurately identify 100 percent of cancers and 100 percent of benign breast lesions, but such a scan does not exist at this time. However, a new technology for scanning small cores of breast tissue removed ...
