A policy of quality control assessment helps to reduce the risk of intraoperative stroke during carotid endarterectomy. (1/180)

OBJECTIVES: A pilot study in our unit suggested that a combination of transcranial Doppler (TCD) plus completion angioscopy reduced incidence of intra-operative stroke (i.e. patients recovering from anaesthesia with a new deficit) during carotid endarterectomy (CEA). The aim of the current study was to see whether routine implementation of this policy was both feasible and associated with a continued reduction in the rate of intraoperative stroke (IOS). MATERIALS AND METHODS: Prospective study in 252 consecutive patients undergoing carotid endarterectomy between March 1995 and December 1996. RESULTS: Continuous TCD monitoring was possible in 229 patients (91%), while 238 patients (94%) underwent angioscopic examination. Overall, angioscopy identified an intimal flap requiring correction in six patients (2.5%), whilst intraluminal thrombus was removed in a further six patients (2.5%). No patient in this series recovered from anaesthesia with an IOS, but the rate of postoperative stroke was 2.8%. CONCLUSIONS: Our policy of TCD plus angioscopy has continued to contribute towards a sustained reduction in the risk of IOS following CEA, but requires access to reliable equipment and technical support. However, a policy of intraoperative quality control assessment may not necessarily alter the rate of postoperative stroke.  (+info)

Intraoperative assessment of technical perfection in carotid endarterectomy: a prospective analysis of 1305 completion procedures. Collaborators of the EVEREST study group. Eversion versus standard carotid endartectomy. (2/180)

OBJECTIVE: to define the incidence of technical defects and the impact of technical errors on ipsilateral carotid occlusion, ipsilateral stroke, and early restenosis rates, we analysed 1305 patients undergoing carotid completion procedures. DESIGN: prospective multicentre study. PATIENTS AND METHODS: adequacy of CEA was assessed intraoperatively by angiography in 1004 (77%), by angioscopy in 299 (22%), and by duplex scan in two patients (1%). Arteriograms and angioscopic findings were interpreted at the time of the procedure by the operating surgeon, who also established the need for immediate surgical revision. RESULTS: perioperatively, 13 major strokes (0.9%, all ipsilateral) and six deaths (0.4%) were recorded. Overall, 112 defects (9%) were identified intraoperatively: 81 (72%) were located in the common carotid artery (CCA) or internal carotid artery (ICA), and 31 (28%) in the external carotid artery. In 48 patients (4%) the defects were revised. Logistic regression analysis revealed that carotid plaque extension >2 cm on the ICA was a positive independent predictor of CEA defects (odds ratio (OR) 1.5p=0.03). A significant association was found between the incidence of revised defects of the CCA and ICA and perioperative ipsilateral stroke (OR 11.5p=0.0002). In contrast, patients with minor non-revised defects had an ipsilateral stroke rate comparable to that of patients with no defects (p=0.4). No significant association was found between revised or non-revised defects and occurrence of restenosis/occlusion at 6-month follow-up. CONCLUSIONS: the incidence of major technical defects during CEA is low, yet the perioperative neurological prognosis of patients with major defects warranting revision is poor. Completion angiography or angioscopy and possible correction of defects did not protect per se from an unfavourable early outcome after CEA. Therefore, surgical excellence is mandatory to achieve satisfactory results after CEA.  (+info)

Valvulotomy of non-reversed saphenous vein bypass grafts: a randomised, blinded, angioscopy-controlled study. (3/180)

OBJECTIVES: to compare the result of vein valve disruption with two different valvulotomes during non-reversed saphenous vein bypass. DESIGN: a randomised, blinded clinical study. MATERIALS AND METHODS: twenty patients undergoing femorodistal non-reversed saphenous vein arterial bypass were randomised into two equal groups. Valve leaflet disruption was performed either with a standard size plastic valvulotome or with a metal valvulotome with an exchangeable cutting head. Valvulotomy was done after full exposure of the vein and completion of the proximal anastomosis. The result was evaluated by a surgeon blinded to the valvulotome used, using angioscopy. RESULTS: a total of 219 valve cusps were inspected with angioscopy. There were 83 completely lysed cusps (69%) by plastic and 76 (78%) by metallic valvulotomes (p=0.14). Of all the incompletely lysed cusps 12 (29%) occurred in the most proximal valve pocket treated with valvulotomy. CONCLUSIONS: no significant difference in performance between the investigated valvulotomes was found. Incomplete valvulotomy occurred mainly in the proximal part of the vein and was obviously caused by a size mismatch between the diameter of vein and the valvulotome. Construction of a valvulotome with a variable diameter cutting head is therefore recommended.  (+info)

Evaluation of disinfection and sterilization of reusable angioscopes with the duck hepatitis B model. (4/180)

PURPOSE: Nosocomial transmission of viral hepatitis and retrovirus infection has been reported. The expected risk is greatest for the hepatitis B virus (HBV). The duck HBV (DHBV) has similar biologic and structural characteristics to HBV and has been adopted as a suitable model for disinfectant testing. METHODS: Angioscopic examination of the external jugular vein was performed on DHBV-infected ducks. After use, the instrument was air dried for 3 minutes. Samples were obtained by flushing the channel with 5 mL of phosphate buffered saline solution. The samples were collected immediately after drying (control), after flushing with 5 mL of water, after glutaraldehyde disinfection for 5, 10, and 20 minutes, and after ethylene oxide gas sterilization. Angioscopes were either precleaned or uncleaned before disinfection/sterilization. Residual infectivity was assessed with inoculation of samples into the peritoneal cavity of day-old ducks (n = 231). RESULTS: DNA analysis results of liver samples showed that all 38 control ducks became infected. The frequency of DHBV infection was reduced to 93% (14 of 15) by flushing the angioscope with 5 mL of sterile water. No transmission occurred after the use of any of the properly precleaned and disinfected/sterilized angioscopes. However, after the use of the uncleaned angioscopes, the transmission rate was 90% (9 of 10) and 70% (7 of 10) after 5 and 10 minutes of contact time, respectively, in 2% glutaraldehyde. Even after the recommended 20 minutes of contact time, there was still 6% (2 of 35) transmission. After ethylene oxide sterilization, two of the recipient ducklings (2 of 35) were infected with DHBV. CONCLUSION: There was no disease transmission after reuse of disposable angioscopes adequately cleaned before disinfection or sterilization. However, if the angioscopes are inadequately cleaned, DHBV can survive despite glutaraldehyde disinfection or ethylene oxide sterilization. This contrasts with previous in vitro and in vivo data with solid surgical instruments. It is postulated that the presence of a narrow lumen or residual protein shielding within the lumen may compromise effective inactivation of hepadnaviruses on angioscopes, with the potential risk for patient-to-patient transmission.  (+info)

Stent attachment site-related endoleakage after stent graft treatment: An in vitro study of the effects of graft size, stent type, and atherosclerotic wall changes. (5/180)

OBJECTIVE: Perigraft endoleakage is a major complication of the endovascular treatment of abdominal aortic aneurysms. The factors that cause this form of endoleakage are not completely identified. The effect of sizing of the prosthesis in combination with either self-expandable or balloon-expandable stents is evaluated in this study. Further, the influence of atherosclerotic changes on endoleakage is evaluated. METHODS: Eight human abdominal aortas were assessed macroscopically at 11 sites for the presence of atherosclerotic changes with intravascular ultrasound scanning (IVUS) and with computed tomography (CT). Five aortas were placed in in vitro circulation with physiologic parameters. After the determination of the proximal and distal landing site of the stent graft, the diameter and surface measurements of the cross sections were taken. The stent graft diameters were chosen from 4-mm undersizing to 6-mm oversizing, both for Gianturco stent grafts (William Cook Europe A/S, Bjaeverskov, Denmark) and for Palmaz stent grafts (Cordis/Johnson & Johnston Co, Warren, NJ). After placement of the stent graft, the diameter and surface measurements of the aortic cross section were determined at the proximal and distal stent attachment sites. The presence and size of the folds at the stent attachment site and the interface with the aortic wall were determined with IVUS and angioscopy. Endoleakage was evaluated with angiography. After angioplasty of the stent attachment site, IVUS, angioscopy, and angiography were repeated. RESULTS: Regarding atherosclerotic changes of the aortic wall, the correlations between clinical impression and CT, clinical impression and IVUS, and CT and IVUS were high (r = 0.77, r = 0.79 and r = 0.79, respectively). For the Gianturco stent grafts, no significant relationship existed between the diameters measured before and after stent graft placement, leading to great differences in intended and achieved oversizing. The achieved oversizing was less in the case of minimal atherosclerotic changes of the aortic wall. The Gianturco stent graft followed the aortic wall closely during the heart cycle. The sizes of the folds of the fabric were clearly correlated with the achieved oversizing (r = 0.83; P =.04) and the grade of endoleakage (r = 0.88; P =.022). Angioplasty after stent graft placement had no effect on the diameter and the grade of endoleakage. Palmaz stent grafts did not follow the aortic wall during the heart cycle. A significant correlation existed between oversizing and both space between aortic wall and stent graft (r = -0.88; P =.02) and grade of endoleakage (r = 0.84; P =.036). Grade of endoleakage in the Palmaz stent graft group was less than in the Gianturco stent graft group. CONCLUSION: With the use of Gianturco stents, a great difference between intended and achieved oversizing is accomplished. The atherosclerotic changes of the aortic wall possibly affect this finding. The configuration of the Gianturco stent results in the formation of fold in the case of oversizing, which is associated with endoleakage. However, the self-expandable character of the stent leads to a close relation to the aortic wall during the heart cycle, and this may possibly accommodate future aortic neck dilation. The Palmaz stent grafts do not follow the aortic wall during the heart cycle, but they do lead to better interface between the graft and the aortic wall, which results in less endoleakage.  (+info)

The use of arm vein in lower-extremity revascularization: results of 520 procedures performed in eight years. (6/180)

PURPOSE: The absence of an adequate ipsilateral saphenous vein in patients requiring lower-extremity revascularization poses a difficult clinical dilemma. This study examined the results of the use of autogenous arm vein bypass grafts in these patients. METHODS: Five hundred twenty lower-extremity revascularization procedures performed between 1990 and 1998 were followed prospectively with a computerized vascular registry. The arm vein conduit was prepared by using intraoperative angioscopy for valve lysis and identification of luminal abnormalities in 44.8% of cases. RESULTS: Seventy-two (13. 8%) femoropopliteal, 174 (33.5%) femorotibial, 29 (5.6%) femoropedal, 101 (19.4%) popliteo-tibial/pedal, and 144 (27.7%) extension "jump" graft bypass procedures were performed for limb salvage (98.2%) or disabling claudication (1.8%). The average age of patients was 68.5 years (range, 32 to 91 years); 63.1% of patients were men, and 36.9% of patients were women. Eighty-five percent of patients had diabetes mellitus, and 77% of patients had a recent history of smoking. The grafts were composed of a single arm vein segment in 363 cases (69. 8%) and of spliced composite vein with venovenostomy in 157 cases (30.2%). The mean follow-up period was 24.9 months (range, 1 month to 7.4 years). Overall patency and limb salvage rates for all graft types were: primary patency, 30-day = 97.0% +/- 0.7%, 1-year = 80.2% +/- 2.1%, 3-year = 68.9% +/- 3.6%, 5-year = 54.5% +/- 6.6%; secondary patency, 30-day = 97.0% +/- 0.7%, 1-year = 80.7% +/- 2.1%, 3-year = 70.3% +/- 3.4%, 5-year = 57.5% +/- 6.2%; limb salvage, 30-day = 97.6% +/- 0.7%, 1-year = 89.8% +/- 1.7%, 3-year = 82.1% +/- 3.3%, 5-year = 71.5% +/- 6.9%. Secondary patency and limb salvage rates were greatest at 5 years for femoropopliteal grafts (69.8% +/- 12.8%, 80.7% +/- 11.8%), as compared with femorotibial (59.6% +/- 10. 3%, 72.7% +/- 10.5%), femoropedal (54.9% +/- 25.7%, 56.8% +/- 26.9%, ) and popliteo-tibial/pedal grafts (39.0% +/- 7.3%, 47.6% +/- 15.4%). The patency rate of composite vein grafts was equal to that of single-vein conduits. The overall survival rate was 54% at 4 years. CONCLUSION: Autogenous arm vein has been used successfully in a wide variety of lower-extremity revascularization procedures and has achieved excellent long- and short-term patency and limb salvage rates, higher than those generally reported for prosthetic or cryopreserved grafts. Its durability and easy accessibility make it an alternative conduit of choice when an adequate saphenous vein is not available.  (+info)

Endovascular-assisted versus conventional in situ saphenous vein bypass grafting: cumulative patency, limb salvage, and cost results in a 39-month multicenter study. (7/180)

OBJECTIVE: In this retrospective multicenter study, the results of a minimally invasive method of endovascular-assisted in situ bypass grafting (EISB) versus "open" conventional in situ bypass grafting (CISB) were evaluated with a comparison of primary and secondary patency, limb salvage, and cost. METHODS: Enrolled in this study were 273 patients: 117 underwent CISB (42 femoropopliteal, 75 femorocrural) and 156 underwent EISB (41 femoropopliteal, 115 femorocrural). EISB was performed with an angioscopic Side Branch Occlusion system and an angioscopically guided valvulotome. All the patients underwent follow-up examination with serial color-flow ultrasound scanning. RESULTS: Both groups had similar comorbid risk factors for diabetes mellitus, coronary artery heart disease, hypertension, and cigarette smoking. The primary patency rates (CISB, 78.2% +/- 5% [SE]; EISB, 70.5% +/- 5%; P =.156), the secondary patency rates (CISB, 84.1% +/- 4%; EISB, 82.9% +/- 5%; P =.26), and the limb salvage rates (CISB, 85.8%; EISB, 88.4%; P =.127) were statistically similar, with a follow-up period that extended to 39 months (mean, 16.6 months; range, 1 to 40 months). In veins that were less than 2.5 to 3.0 mm in diameter, the EISB grafts fared poorly, with an increased incidence of early (12-month) graft thromboses (CISB, 10 grafts, 8.5%; EISB, 24 grafts, 15.3%). However, wound complications (CISB, 23%; EISB, 4%; P =.003), mean hospital length of stay (CISB, 6.5 days +/- 4.83; EISB, 3.2 days +/- 3.19; P =.001), and mean hospital charges (CISB, $25,349 +/- $19,476; EISB, $18,096 +/- $14,573; P =.001) were all significantly reduced in the EISB group. CONCLUSION: The CISB and EISB midterm primary and secondary patency and limb salvage rates were statistically similar. In smaller veins (< 2.5 to 3.0 mm in diameter), however, EISB is not appropriate because overly aggressive instrumentation may cause intimal trauma, with resultant early graft failure. With the avoidance of a long leg incision in the EISB group, wound complications and hospital length of stay were significantly reduced, which lowered hospital charges and justified the additional cost of the endovascular instruments. When in situ bypass grafting is contemplated, EISB in appropriate patients is a safe, minimally invasive, and cost-effective alternative to CISB.  (+info)

Minimally invasive approach for aortic arch branch vessel reconstruction. (8/180)

Minimally invasive aortic arch branch vessel reconstruction was successfully accomplished in four patients over the past 3 years. There were no operative complications. Three patients had an uneventful hospital course, ranging from 3 to 5 days. The fourth patient with multiple medical problems and severe peripheral vascular disease had a prolonged hospital course for reasons unrelated to the surgical procedure. This minimally invasive surgical exposure can be used to effectively and safely repair innominate and left common carotid artery lesions.  (+info)

Annual angiographic assessment to determine the presence or progression of allograft coronary artery disease (CAD) has been unable to modify the natural history of this disease. Coronary angioscopy is a sensitive method to detect the early presence of coronary artery disease and in a retrospective analysis severity of CAD by angioscopy correlated with the time since transplantation. The purpose of this study was to prospectively evaluate progression of coronary artery disease over a one year period in 40 cardiac transplant recipients. The progression of coronary artery disease as assessed by angioscopy is directly related to time after transplantation and therefore angioscopy may be the method of choice for detection and evaluation of therapeutic regimens to control allograft coronary artery disease ...
It has been proposed that atherosclerotic plaques vulnerable to disruption and thrombosis have a lipid-rich core covered by a thin cap. However, a method to detect those plaques has not been established. We hypothesized that such plaques are yellow due to reflection of the yellow lipid core through a thin cap which may be detected by angioscopy. We developed software to quantify yellow color saturation in digitized angioscopic images ...

The study by den Heijer and colleagues is of interest to both interventional cardiologists and internists. The availability of low-profile, flexible, and steerable angioscopic systems has allowed the routine percutaneous application of this technology. Interpretable images can now be obtained in most patients having interventional procedures, although the technique still has important limitations. Problems remain with aiming the angioscope, and a clear imaging field cannot always be obtained. The widespread availability of second-generation interventional technologies, including stents, atherectomy catheters, and local drug delivery systems, give the interventionist a choice of therapies. Precise knowledge of coronary morphology may have an important effect on the decision of which technique to use to treat a given lesion. The study by den Heijer and colleagues suggests that, in a few patients, the angioscopic information was useful to the clinician. These results, however, cannot be ...
Background: Although sirolimus-eluting stent (SES) has significantly reduced in-stent restenosis by inhibiting neointimal hyperplasia, insufficient neointimal coverage after stenting may result in adverse outcomes. Determinants of neointimal coverage following SES, however, are poorly understood.. Methods: We evaluated 28 SES lesions using both angioscopy and intravascular ultrasound (IVUS). Degree of neointimal coverage was judged by angioscopy at follow-up (11 ± 6 months): complete/incomplete coverage, based on whether the stent struts were embedded by the neointima. Minimal stent area (MSA), external elastic membrane (EEM), lumen cross-sectional area (CSA) and plaque burden (EEM minus lumen/EEM CSA) were measured by IVUS at stent implantation. Both proximal and distal references were used. Stent expansion was assessed by stent expansion index (SEI) as MSA/reference EEM CSA. Under-expansion was defined as SEI , 0.4. Incomplete apposition was defined as the lack of contact between any strut ...
The present study compared the vascular lumen/stent surfaces in patients following PES implantation with those following SES using angioscopy. Late loss was slightly, but statistically greater in PES than in SES. Although 72% of SES showed the dominant NIC of grade 1, PES showed widely dispersed NIC grades. Within the stents, NIC was more heterogeneous in PES than in SES. Thrombi were more frequently observed in PES (43%) than in SES (19%, p = 0.04). Yellow plaques were commonly detected both in PES (83%) and in SES (78%, p = 0.76).. Late losses in each group of this study were similar to those found in several other clinical studies for these stents (1,2,17). Similar to SES, PES is one of the first generation DES to reduce LL and target lesion revascularization by inhibiting neointimal hyperplasia. It has been pointed out, however, that incidence of LST may be higher following PES or SES placements than following BMS placements (3-6). Since the beginning of the BMS era, pathological studies ...

Identifying cell-enhancement strategies, be it genetic modification (1) or small molecule antagonism (2), is essential to improve the therapeutic efficacy of cell-based therapies. Indeed, transplanted cells in a wide variety of models demonstrate poor engraftment, with high rates of cell attrition. Herein, we highlight important differences in GSK3β signaling as a factor for enhanced EPC senescence in DM resulting in accelerated rates of apoptosis. Moreover, using a proteomics approach, we identified upregulation of cathB as protective for reductions in basal and stress-induced apoptosis. Finally, in a xenotransplant model, we confirm that cathB activity is required for GSKi-induced improvements in EPC mediated arterial repair.. Patients with DM have increased rates of cardiovascular disease and markedly higher rates of in-stent restenosis after revascularization. This, in part, is owing to attenuated EPC function in patients and fewer circulating cells (16). Multiple mechanisms of EPC ...

Drug-eluting stent (DES) achieved significant reduced restenosis, however the safety of efficacy of DES in acute myocardial infarction (AMI) are still controversial. In this study, we compared angioscopic parameters between DES and bare metal stent (BMS) in patients with AMI. Eighty-seven consecutive patients who received DES or BMS for AMI were enrolled. At 6-month after AMI, coronary angiography was performed in all patients. We performed coronay angioscope (CAS) if the patients did not show significant in-stent restenosis (,50% stenosis). Using CAS, we evaluated the maximum and minimum grade of neointimal coverage within one stent using the following CAS score: 0: stent struts were exposed similary to right implantaiton, 1: stent were covered by very thin neointima, 2: struts were embedded but visible and 3: struts were fully embedded and invisible. We adopted minimium grade as the magnitude of neointimal coverage and calculated heterogeneity score as the following formula: (maximum grade) ...

Intravascular ultrasound is a new method for visualizing the details of vascular pathology, providing high resolution images of plaque and thrombus. This review summarizes the potential applications of ultrasound imaging in the guidance of balloon angioplasty, atherectomy, laser ablation and stenting. Ultrasound differs from angiography and angioscopy in its ability to penetrate below the surface of the vessel lumen, demonstrating specific aspects about the distribution and composition of plaque. Because the different layers of the arterial wall have different acoustic properties, ultrasound catheters are able to define the layers of normal wall in comparison with plaque. Particularly in combination with therapeutic techniques designed to remove or ablate plaque, ultrasound may prove useful in maximizing the amount of plaque treated and minimising trauma to normal vessel wall components. Combined imaging/therapeutic devices are in the pilot phase of development and show promise for enhancing the ...

To allow for the differences in yellow color in each plant extract primarily due to varying amounts of contaminating photosynthetic pigments, it was necessary to blank each extract separately with diluted extract in buffer lacking the GUS substrate, PNPG. Once you have obtained corrected absorbance values by subtracting the absorbance due to yellow color that is not related to PNPG breakdown, you also must normalize the activities further so that you can compare plants. Typically activities are expressed on a per mg fresh weight or protein basis. Because the method used to cut the tissue disks produce tissue pieces of a uniform size we will express our enzyme activities on a per disk basis. Calculate the GUS activity found in each of your extracts as: Activity = nmoles product formed/minute-leaf disk. You may then compare your data with those of your classmates ...

Late and sudden thrombotic coronary occlusion after percutaneous coronary interventions was first noted as a significant problem 2 to 15 months after brachytherapy (22). In contrast, meta-analyses of initial long-term outcomes after sirolimus-eluting (10,23) or paclitaxel-eluting stent implantation (12) pointed to the overall benefit of DES compared with BMS in selected patient groups and suggested no increased hazard of stent thrombosis compared with BMS use. However, there were case reports (8,16) demonstrating the occurrence of late stent thrombosis after DES implantation associated with a high risk of death or nonfatal MI. Reasons for thrombotic events were described in experimental (24) and autopsy studies (25): DES may delay endothelialization and impair intimal healing, partly in association with hypersensitivity and inflammatory reactions, and thereby extend the time window during which stents are prone to thrombosis (8). This has been confirmed recently by angioscopic findings (26). Two ...
The extent of luminal narrowing varies with underlying plaque morphology. TCFAs and fibroatheromas have the least luminal narrowing while lesions with acute plaque rupture, haemorrhage, or healed repair sites show the most stenosis. Over 74% of TCFAs have , 75% cross sectional area luminal narrowing (equivalent to , 50% diameter stenosis). Healed and acute plaque ruptures show the greatest luminal narrowing with 46% and 43%, respectively, containing , 75% cross sectional area narrowing. In contrast, only 26% of TCFAs show severe luminal narrowing (fig 3B). In a population where sudden cardiac death is the first manifestation of coronary disease, these morphologic findings strongly suggest that TCFAs are precursors to acute ruptures and healed plaque ruptures are often clinically silent.. TCFAs with ⩽ 50% diameter stenosis may be the ideal candidate lesions one should first attempt to identify and treat as a measure to reduce the incidence of myocardial infarction in high risk patients. If a ...

Hi! Im a vet student; Ive just necropsied a pigeon and found a green liver with two white plaques. What could be happening? Is it a sign of toxicity or infection, or is it just normal colour variation? The pigeon was previously diagnosed to have Candidiasis because of white-yellowish masses in the mouth. When I did the swab examination, I found hyphae but couldnt determine yet whether its Candida. Respiratory system got no lesion, unless some compaque-white appearance of the trachea. Digestive system got severe lesion in the crop, where theres some brown crusts. Is it a sole Candida infection or perhaps I should consider differential diagnose like Pox virus or Salmonella? I cant find any colour picture reference that match the lesion of my pigeon.. Could you please recommend me any book or online atlas? Thanks a million!. ...
Purpose: : To evaluate the clinical, histopathologic and genetic features of retinoblastoma (RB) in children over age 5 years. Methods: : Of 90 consecutive patients with RB who presented to the Retina Service at the Massachusetts Eye and Ear Infirmary, 6 patients (6.7%) had initial diagnosis after age 5 years. 4 had active tumors (4.4% of all cases) and 2 had inactive tumors (retinoma). Genetic testing for RB1 mutations was performed on constitutional and tumor DNA in 2 cases. Results: : There were 2 boys and 2 girls, all unilateral with no family history, ranging in age from 6 to 11 years (mean 8 years). 3 (2 girls, 1 boy) with unilateral decrease in vision (1 symptomatic, 2 by vision screen), total retinal detachment (RD) with vascular dilatation and telangiectasia were referred with diagnosis of Coats disease. 2 had RD in contact with the lens and third had tumor spherules in the vitreous. White plaques or tumors with dilated vessels that dive or arise from them were seen. Ultrasound (US) and ...
The researchers believe that it might ultimately be possible to forestall or even prevent the development of atherosclerosis by injecting these cells into patients, or to induce the patients own stem cells to differentiate into progenitor cells capable of arterial repair.. "Our studies indicate that the inability of bone marrow to produce progenitor cells which repair and rejuvenate the lining of the arteries drives the process of atherosclerosis and the formation of plaques in the arteries," said Duke cardiologist Pascal Goldschmidt, M.D., chairman of the Department of Medicine. "For a long time weve known that aging is an important risk factor for coronary artery disease, and weve also known that this disease can be triggered by smoking, bad diet, diabetes, high blood pressure and other factors.. "But if you compare someone who is over 60 with someone who is 20 with the same risk factors, there is obviously something else going on as well," he continued. "The possibility that stem cells may ...

Vanguard is well known for pioneering index funds, and index investing remains a vital part of Vanguards business strategy. However, the fund family also has a number of actively managed funds that seek to outperform their benchmarks, rather than simply match them.. However, when a fund fails to beat its benchmark and instead tends to see its returns align closely to broad market averages, investors have to ask themselves whether the returns warrant the higher expenses associated with actively managed funds. Vanguards Growth Equity fund is an example of this phenomenon; despite a relatively high (for Vanguard) expense ratio of 0.72%, the fund has fallen in the bottom 20% of its fund category over long periods of time. If youre paying more and not getting better performance, you may be better off sticking with one of Vanguards index funds.. A similar pattern exists with some special classes of funds. For instance, the Fidelity Advisor fund mentioned above looks pretty similar to another fund ...

Medical literature has recently focused on very late stent thrombosis (VLST) after drug-eluting stent implantation, while its mechanistic issue was not fully explored in the bare-metal stent (BMS) era. The first case is a 59-year-old man presenting with inferior non-ST-segment elevation myocardial infarction, 4 years after BMS implantation (NIR 3.5/18 mm, Boston Scientific, Galway, Ireland) for a chronic total occlusion lesion in the proximal right coronary artery. Coronary angiograms showed Thrombolysis In Myocardial Infarction (TIMI) flow grade 1 and filling defects in the BMS deployed previously, and massive red thrombi attaching to uncovered stent struts were found by angioscope (Fig. 1,Online Video 1). Thrombectomy and adjunctive balloon angioplasty were performed based on the angioscopic findings, and TIMI flow grade 3 was obtained. The second case is a 71-year-old man who was admitted for a diagnosis of inferior non-ST-segment elevation myocardial infarction 10 years after a treatment ...

A method of printing an image onto a substrate includes the steps of determining a difference in intended color intensity between a first pixel and a second pixel; adjusting the intended color intensity of the second pixel based on the determined difference; and depositing a colorant onto the substrate at the first pixel and at the second pixel at the adjusted intended intensity, so as to enhance the appearance of the image on the substrate. The current system has particular utility in enhancing the appearance of fine images such as one pixel wide, vertical and diagonal lines in a printing system which utilizes printhead heating elements that are larger in the vertical direction than in the horizontal direction.

Each well of the strip is coated with a specific capture antibody to detect its corresponding cytokine in the sample. Therefore, 8 different proteins can be measures simultaneously. The test sample reacts simultaneously with two antibodies, resulting in the cytokines being sandwiched between the solid phase and enzyme-linked antibodies. After incubation, the wells are washed to remove unbound-labeled antibodies. The HRP substrate, TMB, is then added and causes a blue color change. The reaction is then terminated with Stop Solution, resulting in a yellow color. The concentrations of oxidative stress cytokines are directly proportional to the color intensity of the test sample. Absorbance is measured spectrophotometrically at 450 nm. The expression levels of these cytokines can be quantitatively compared between samples.. ...
The Yellow Ribbon - Courtesy of James Corner Field Operations. The Yellow Ribbon Wayfinding system seems to be about helping users navigate the maze like skyway and to improve how it relates to the streetscape below. Even for an experienced user, the skyway can be very disorienting. To reliably get from one place to another requires either practiced knowledge or a map, and finding an exit can be frustrating to say the least. When users enter a new building they experience a shift of style that reflects the architecture and design taste of its era and the quality of directional signage is highly variable. While there is a certain charm and novelty to the disconnected nature of the skyways, the incoherency of the network is problematic. The proposal advocates for yellow color coding of the carpets or walls of the skyway to help the user stay parallel with Nicollet Avenue and incorporates more regular interfaces with the street. Like many of the other ideas in this proposal it is not entirely novel ...

The presence of bilirubin in amniotic fluid, which results in a yellow color, is an indicator of fetal erythroblastosis. Visual inspection of amniotic fluid is unreliable because bilirubin is not the only cause of an excessive yellow color; therefore, the presence of bilirubin must be confirmed with spectrophotometric methods. Meconium may contribute a green color (biliverdin) that can obscure the color of bilirubin and hemoglobin.. ...
If the child continues to use the overlay through choice or the teacher/parent reports an improvement then it has most likely been beneficial. The overlay is usually given for a trial period of approx. 6 weeks. Spectacles with Precision Tinted Lenses can then be prescribed following an Intuitive Colorimetry assessment. These are more convenient/versatile as they can be used with white boards and computer screens. The Precision Tinted Lens is more accurate than the overlay as many more colour combinations are used and the tint will vary from person to person. The colour of the lens may differ from that of the initial overlay used ...

from which the epidermis has been removed previously. A section of the bore, taken during the operation, shows that it is convex, and contradicts the received notion of the operation being performed bj the action of the ribbon, which being in the centre of the proboscis, would perforce wear the middle of the bore deepest, but this is not the case. The animal makes no movement of a rotatory kind or otherwise, during the operation. It takes about two days to get through the shell, when it eats about two-thirds of a moderate-sized mussel, which seems to satisfy hunger for about three weeks."[1].

We measured a number of geochemical rock standards using three different techniques: elemental analyzer (EA) mass spectrometry, colorimetry, and fluorometry. The fluorometry approach is a novel adaptation of a technique commonly used in biologic science, applied herein to geologic NH4+. Briefly, NH4+ can be quantified by HF dissolution, neutralization, addition of a fluorescing reagent, and analysis on a standard fluorometer. We reproduce published values for several rock standards (BCR-2, BHVO-2, and G-2), especially if an additional distillation step is performed. While it is difficult to assess the quality of each method, due to lack of international geologic N standards, fluorometry appears better suited to analyzing mineral-bound NH4+ than EA mass spectrometry and is a simpler, quicker alternative to colorimetry ...
Choice of Tissue Adhesives to Be Tested. The TA can be divided into two basic categories according to their origin, biological origin and synthetic origin. The main representative of the biological origin TA is the fibrin adhesive and the synthetic origin TA is the cyanoacrylate. The fibrin adhesive is made up of two basic components, the thrombin and the fibrinogen. The fibrinogen is the source of fibrin which represents the basic clotting element. Each of these ingredients is put into syringes apart from each other displayed side by side in a system that allows the mixing of the products only by the moment of application. The components interact along the application to form a stable fibrin clot. The relative rate of thrombin is that which will determine the rate of clot formation and the adhesion strength by the final phase of fibrin application[9,10]. As fibrin adhesives simulate the last clotting phase, they are autonomous and independent of body coagulation and, as a result, are also ...
What Can Quercetin Do for You? It has been determined through sports science and nutritional research that quercetin can do quite a bit for your performance during exercise. Quercetin is a bioactive compound and phytonutrient. Phytonutrients give fruits and vegetables their color. Quercetin is found in apples, onions, and other fruits and vegetables that have a yellow color or yellow hue. This flavonoid has been found to have many benefits for humans. When Quercetin is used in products it will give a yellow color to the supplement. The brighter the yellow, the more pure the quercetin. Beachbody Performance Energize and Hydrate are two of the best supplements on the market that contain quercetin. Their day-glow yellow color proves that the quercetin is very pure. ...
