| scanning electron microscopy evaluation of the abiomed 5000 ventricular support system after clinical biventricular assistance. | twenty-nine days after implantation of an abiomed 5000 biventricular support system for otherwise intractable end-stage cardiomyopathy, the inner surfaces of the device were examined by means of scanning electron microscopy (sem). sem showed clean surfaces inside the blood sacs, with only rare fibrin deposits. there were platelet adhesions on the ventricular side of the artificial atrioventricular valves; no deposits were on the opposite side. structural deterioration of the closing edge of the ... | 2008 | 2288748 |
| [outpatient electromagnetic therapy combined with hyperbaric oxygenation in arterial occlusive diseases]. | the authors first applied hyperbaric oxygenation (hbo) in the outpatient clinic in 1968. barotherapy was conducted in 107 outpatients whose ages ranged from 27 to 80 years; they had various stages of the disease of 5- to 20-year history. in 70 patients treated for obliterating diseases of the vessels by hbo in a complex with magnetotherapy by means of magnetophors, the remission lasted 1-2 years; patients treated by hbo alone had a 3-8 month remission. a prolonged positive effect was produced in ... | 2008 | 2292853 |
| real estate market trends and the displacement of the aged: examination of the linkages in manhattan. | a real estate market trends analysis of a low-income area on the upper west side of manhattan revealed increases in residential properties of 400% during 1980-1988, and 1,754% in the manhattan valley area of this community, compared with 203% in all of manhattan. an analysis of databases revealed a depletion of 51.9% of the single-room occupancy housing stock in this area. a survey of 115 seniors indicated a population at risk of displacement and vulnerable to homelessness. | 2008 | 2276640 |
| interganglionic axonal transport of neuropeptides in aplysia. | the transport of neuropeptides between central ganglia was studied in aplysia. peptide transport was determined by incubating ganglia with 35s-methionine and measuring the appearance of labeled peptides in connected ganglia. selected interganglionic connectives were left intact and passed through a diffusion barrier separating the ganglia. labeled peptides transported between ganglia included fmrfamide, myomodulin, and pedal peptide. each of these peptides has been shown to be physiologically ac ... | 2009 | 2795162 |
| single tuberculous stricture in the jejunum: report of 2 cases. | intestinal tuberculosis is now considered rare. it usually involves the ileocecal region and often produces multiple ulcers in the small intestine. this is a report of 2 patients who presented with a single tuberculous stricture in the jejunum, an exceedingly rare manifestation of this disease. the stricture in each case consisted of a short girdle ulcer with irregular margins, detected by double-contrast studies of the small intestine. | 2009 | 2806816 |
| anti-thrombin activities of heparin. effect of saccharide chain length on thrombin inhibition by heparin cofactor ii and by antithrombin. | the interactions of two proteinase inhibitors, heparin cofactor ii and antithrombin, with thrombin are potentiated by heparin. using two methods, we have studied the potentiating effects of a series of heparin (poly)saccharides with high affinity for antithrombin and mean mr ranging from approx. 1700 to 18,800. first, catalytic amounts of heparin (poly)saccharide were added to purified systems containing thrombin and either heparin cofactor ii or antithrombin. residual thrombin activity was dete ... | 2009 | 2818566 |

| synthesis of new bile acid analogues and their metabolism in the hamster: 3 alpha, 6 alpha-dihydroxy-6 beta-methyl-5 beta-cholanoic acid and 3 alpha, 6 beta-dihydroxy-6 alpha-methyl-5 beta-cholanoic acid. | this paper reports the chemical synthesis of two new bile acid analogues, namely, 3 alpha, 6 beta-dihydroxy-6 alpha-methyl-5 beta-cholanoic acid from 3 alpha-hydroxy-6-oxo-5 beta-cholanoic acid and describes their metabolism in the hamster. a grignard reaction of the oxo acid with methyl magnesium iodide in tetrahydrofuran gave two epimeric dihydroxy-6-methyl-cholanoic acids which were separated as the methyl esters by silica gel column chromatography. the configuration of the 6-methyl groups wa ... | 2009 | 2794784 |
| immunologic assessment determined by response to il-2 and immunophenotyping of tumor-infiltrating lymphocytes, of invaded and non invaded lymph nodes and of peripheral blood lymphocytes from twenty-one patients with primary laryngeal cancer. | the aim of the study was to identify the lymphocyte sets and/or subsets possibly involved in the response to malignant cells. for this purpose we have investigated both the cells at the tumor site, i.e. tumor-infiltrating lymphocytes (til), and the cells present in the draining lymph nodes, either invaded or non invaded, as well as the peripheral blood lymphocytes from twenty-one patients with primary laryngeal epidermoid carcinoma. the functional assay was carried out by the proliferative respo ... | 2009 | 2786668 |
| a quality assurance model of operative mortality in coronary artery surgery. | quality assurance in coronary artery bypass grafting (cabg) surgery requires a comparison of operative mortality against an accepted standard of care. raw mortality statistics are unacceptable in this context, and risk factor analysis is essential. however, this principle has not been adequately demonstrated in previous reports. our goal in this study was to develop a risk model of accepted cabg mortality and illustrate its proper use in coronary artery surgery. the model was derived from a baye ... | 2009 | 2786391 |
