<h3>Background/aims</h3> To determine to what extent subjects implanted with the Argus II retinal prosthesis can improve performance compared residual native vision in a spatial-motor task. <h3>Methods</h3> High-contrast square stimuli (5.85 cm sides) were displayed random locations on 19″ (48.3 cm) touch screen monitor located 12″ (30.5 front of subject. Subjects instructed locate and centre system then off (40 trials each). The coordinates location touched recorded. <h3>Results</h3>...
The Argus II epiretinal prosthesis has been developed to provide partial restoration of vision subjects blinded from outer retinal degenerative disease. Participants were surgically implanted with the system in United States and Europe a single arm, prospective, multicenter clinical trial. purpose this investigation was determine which factors affect electrical thresholds order inform surgical placement device.Electrode-retina electrode-fovea distances determined using SD-OCT fundus...
Epiretinal prostheses are being developed to bypass a degenerated photoreceptor layer and excite surviving ganglion inner retinal cells. We used custom microfabricated multielectrode arrays with 200-microm-diameter stimulating electrodes 10-microm-diameter recording stimulate record neural responses in isolated tiger salamander retina. Pharmacological agents were isolate direct excitation of cells from other Strength-duration data suggest that, if amplitude will be for the coding brightness...
The Argus II 60 channel epiretinal prosthesis has been developed in order to provide partial restoration of vision subjects blinded from outer retinal degenerative disease. To date the device implanted 21 as part a feasibility study. In 6 month post-implantation door finding and line tracking orientation mobility testing, have shown improvements 86% 73%, respectively, for system on vs. off. high-contrast Square Localization tests using touch screen monitor 87% tested performed significantly...
<b>Background:</b> Tuberculosis is one of the major health problems in India. Genitourinary tuberculosis comprises 20% all extrapulmonary tuberculosis, and most common system to be affected by this disease. The recent surge incidence HIV-infected patients India has further ignited fury. Though members Mycobacterium species are well identified, could not controlled due its complex etiopathogenesis genetic background.<br><b> Pathological Spectrum:</b> spectrum pathological changes...
Background Interleukin (IL)-4, IL-13, IL-17, IL-22 and IL-3 are overexpressed in prurigo nodularis (PN). They mediate their action via the Janus Kinase (JAK) Signal transducer activator of transcription (STAT) pathway. Objectives Our aim was to study expression tissue STAT1, STAT3, STAT6, as well efficacy JAK-STAT inhibitor, tofacitinib, PN. Methods A prospective conducted a tertiary care hospital. Patients with PN were recruited after excluding secondary causes. Pruritus graded using...
Nerve destruction is central to the pathogenesis and clinical manifestation of leprosy reactions (LRs). However, pathological changes in dermal nerves LRs have not been clearly elucidated. Hematoxylin eosin (H&E) staining may fail accurately identify fragmented nerves, special stains be required. We recruited 56 patients with clinically diagnosed as cases 30 nonreactional controls. Number level nerve edema, relation granulomas perineuritis, pattern involvement, quantification each were...
Ellagic acid (EA), a plant phenol found in various fruits and nuts, was examined for its ability to inhibit aflatoxin B 1 (AFB ) mutagenesis strain TA 100 of Salmonella typhimurium . In the presence rat liver S-9 microsomal preparation, EA (1.5 μ g/plate) inhibited number mutations induced by AFB, (0.5 50%. at dose 1000 g/plate mutation frequency >90%. also tested DNA binding adduct formation AFB cultured explants trachea human tracheobronchus. Explants were incubated medium containing...
To correlate cirrhosis histology and Laennec fibrosis scoring with portal pressure, as determined by hepatic venous pressure gradient (HVPG).One hundred four patients biopsy-proven known HVPG were included in the study. Semiquantitative of 12 histological parameters quantitative assessment morphometry for septal thickness nodule diameter image analysis performed. subgrading clinical staging also There significant positive correlations between grade (P < 0.001), micronodularity presence thick...
We aimed to determine the characteristics of patients with celiac disease and differences between those who presented during adolescence or adulthood.We retrospectively reviewed case records 233 consecutive were diagnosed at 12-18 years >18 age. The diagnosis was made on basis modified European Society Pediatric Gastroenterology, Hepatology Nutrition criteria.The after 18 age in 153 (65.7%) patients. Median duration symptoms 54 months (range 1 month 29 years). In all, 103 (44.2%) atypical...
UNRAVELING AND FRACTURE of electrolytically detachable coils (Guglielmi coils) may occur during treatment intracerebral aneurysms. Retrieval the detached coil is difficult using existing snare technology, and intraluminal cause parent vessel thrombosis or distal embolization. We report a case unraveling fracture Guglielmi that was successfully retrieved dual guidewire technique. The technique evaluated in an vitro model 10 varying sizes diameters, allowed successful retrieval all trials.
✓ A case is presented of severe atherosclerosis the basilar artery, successfully treated with percutaneous transluminal balloon angioplasty. Crescendo daily transient ischemic attacks consisted alternating hemiplegia and were refractory to medical management, including anticoagulation therapy. The clinical course, endovascular treatment, results are described. Prior published experiences this condition reviewed.
Prurigo nodularis (PN) is a chronic dermatologic condition manifesting as multiple papulonodular lesions occurring on the background of intense pruritus. PN could be primary or secondary. The exact immune pathogenesis not yet clear, and pathways are proposed with JAK-STAT pathway rarely being investigated.In this study, our aim was to assess role Th cells in by comparing expression STAT 1, 3, 6 involved normal skin prurigo nodularis.A total 49 clinico-histopathologically proven cases were...
Renal Cell Carcinoma (RCC) is a lethal cancer with propensity for wide metastasis. The patterns of metastases are not clearly defined, and patients can present metastasis to unusual sites at the time diagnosis primary tumor or years after radical nephrectomy. Individual diagnostic surgical approaches needed achieve complete resection disease-free margins, even in presence metastatic sites, multifocality, history previous metastasectomy. This provides palliation symptoms an opportunity...
As microelectrodes gain widespread use for electrochemical sensing, biopotential recording, and neural stimulation, it becomes important to understand the dependence of impedance on microelectrode size. It has been shown mathematically that a disc electrode, coplanar in an insulating substrate exposed conducting media, exhibits inhomogeneous current distribution when potential step is applied. This known as primary distribution, its derivation also yielded analytic solution electrical...
