Aspiration is defined as the inhalation of oropharyngeal or gastric contents into the larynx and lower respiratory tract. 1 2 Several pulmonary syndromes may occur after aspiration, depending on the amount and nature of the aspirated material, the frequency of aspiration, and the host's response to ...

... systolic blood pressure by an average of 2.0 mm Hg and diastolic blood pressure by an average of 1.0 mm Hg in normotensive subjects. 14 Potassium Content of Sodium-Rich Diets As compared with diets based on natural foods, diets based on processed foods are high in sodium and low in potassium. 3 10 For ...

... bacteriophages, each bearing a different antibody of a single specificity on its surface and containing the genes for that antibody. 115 When the contents of this library are poured onto antigen-coated plastic dishes, phages bearing the relevant antibody will bind to the antigen, and those that do not ...

In the issue of April 26, 2001, we published a study by Jon Sudbø et al. 1 Figures 3B and 3C of that article, which purport to represent two different patients and stages of oral epithelial dysplasia, are in fact different magnifications of the same photomicrograph. Because the results of another ...

... renal disease undergo hemodialysis three times per week. The dialysis prescription is adjusted to remove about two thirds of the total-body urea content during each treatment ( Figure 1). This standard was adopted after clinical trials showed that to a point, patient outcomes improve with increasing ...

... proximal stomach serves as the reservoir of food, and the distal stomach as the grinder. 11 The physical nature, particle size, and fat and caloric content of food determine its emptying rate ( Figure 1). Non-nutrient liquids empty rapidly; the rate is fastest when there is a large volume. If there are ...

... validity score of 7 or higher were included in the study. Previous work has shown this method of selecting indicators to be reliable and to have content, construct, and predictive validity in other applications. 15 16 17 The criteria for selecting the clinical areas, literature reviews, procedures followed ...

... designated boxes on rating forms and narrative comments), deans' letters of recommendation to residency programs, and any documents in the students' files dated before graduation. The course-evaluation forms contained items intended to capture the entirety of professional behavior. Overall Unprofessional Rating ...

... The primary abnormality is rapid or slow compression of all cardiac chambers as a result of increasing intrapericardial pressure. The pericardial contents first reach the limit of the pericardial reserve volume 6 — the volume that would just distend the pericardium — and the rate of expansion then ...

... effects of glucocorticoids on the growing skeleton. We determined the effects of long-term therapy with high-dose glucocorticoids on the bone mineral content of the lumbar spine and whole body relative to bone size and body size in children and adolescents. Methods Study Subjects The study subjects were ...

... aberration of DNA content (ploidy) in carcinogenesis. 25 Three previous studies of the prognostic value of DNA quantitation in premalignant oral lesions included fewer than 25 patients with at least five years of follow-up. 26 27 28 In this report we describe the prognostic value of the DNA content in dysplastic ...

... risk. In this regard, studies measuring triglyceride content of muscle-biopsy specimens 6 or intramyocellular lipid content by means of proton ( 1H) magnetic resonance spectroscopy 7 8 9 indicate a strong relation between intramuscular lipid content and insulin resistance in skeletal muscle. Studies have ...

... occupational settings. 7 In this study, we sought to determine the association between the carbon content of airway macrophages and lung function in a group of healthy children and the association between carbon content and variables that may affect individual exposure — such as exercise, 8 body-mass index ...

... subjects were interviewed by the research dietitian at the Frederic C. Bartter General Clinical Research Center and instructed not to change the calorie content of their diet or their level of physical activity. The subjects were given placebo pills, and compliance was assessed by means of a pill count on follow ...

... patients with unstable angina, but not in those with stable angina or in controls. Activation was detected by measuring the neutrophil myeloperoxidase content, which is an index of more advanced inflammatory activation than that identified by measuring CD11b and CD18 expression. 17 18 We ascertained whether ...

... glucocorticoids does not appear to be associated with deficits in bone mineral content in children with the nephrotic syndrome — results that differ from ours. 2 An important observation was a lower bone mineral content at the spine after correction for the body-mass index. The earliest changes of ...

... undergoing apoptosis, can be identified easily, 62 whereas apoptotic loss of melanocytes has never been reported. One possible explanation is the high content of antiapoptotic proteins such as Bcl-2 in melanocytes. 63 64 65 Basal keratinocytes also have relatively high levels of Bcl-2 and related proteins ...

... A contrast-enhanced CT scan ( Figure 2) shows a smooth, sharply demarcated, round mass in the right lower lobe with peripheral enhancement. The contents of the mass are of low attenuation, which is characteristic of fluid. The mass abuts the chest wall without invading it. A smaller, irregular mass ...

... transfected with wild-type yeast Bcs1, wild-type human BCS1L, empty vector (pMGL3), or human mutant BCS1L. Mitochondrial Extraction, Analysis, and Content Actively growing transformed lymphocytes were washed, and a crude mitochondrial fraction was extracted as previously described. 17 Mitochondrial preparations ...

Bone strength depends on material properties, such as tissue mineral content. Certain structural characteristics of the skeleton — for example, size, shape, and the three-dimensional architecture — also affect bone strength. The observed increase in the fragility of bone with age is regarded as predominantly ...
