(9) This phenomenon suggests that adsorption by asbestiform minerals may modulate biological processes by inducing a conformational change in biological macromolecules as a result of coulombic interaction between the surface charge of the fiber and the hydrophilic groups on the macromolecule.
(10) A B-reader confirmed that 355 of 9,442 patients who were at least 40 y of age (3.8%) had a relevant abnormality; 60% of them reported occupational exposure to asbestiform minerals, and another 15% had a chest condition or injury that could have accounted for the abnormal radiograph.
(11) One of the gangue minerals is the amphibole grunerite, whose asbestiform variety is called amosite.
(12) The amount of O2- released from AM in response to dusts was then determined by measuring SOD-inhibitable reduction of cytochrome C. All asbestiform fibres caused a significant (p less than 0.05) increase in generation of O2- from epithelial cells, whereas non-fibrous particles were less active at comparable concentrations.
(13) The ability of different types of asbestiform minerals to enhance or suppress the levels of fibrous collagen in cultures of lung fibroblasts was tested.
(14) Decreased one-sec forced expiratory volume and forced vital capacity were associated with exposure to respirable particulate and asbestiform fibers.
(15) Although no type of asbestos could be found in Tuzköy and its vicinity, the asbestiform mineral zeolite was found in soil samples from the roads and fields of Tuzköy, in its building stones, and in lung tissues of the villagers.
(16) Three classes of macromolecules (i.e., DNA, RNA, and protein) were shown to be adsorbed to asbestiform minerals.
(17) Chest radiographs were re-evaluated from 439 active and retired tireworkers previously designated as having a condition consistent with an asbestiform mineral exposure.
(18) The results from the most relevant studies emphasize the fact that the large majority of mesotheliomas are associated with exposure to asbestos or asbestiform fibers.
(19) Two other asbestiform minerals, crocidolite and tremolite, were ineffective in this assay system.
(20) The percentage of cases with abnormalities consistent with an asbestiform mineral exposure found separately by the three radiologists was 3.7, 3.0, and 2.7%.
Flexibility
Definition:
(n.) The state or quality of being flexible; flexibleness; pliancy; pliability; as, the flexibility of strips of hemlock, hickory, whalebone or metal, or of rays of light.
Example Sentences:
(1) Many speak about how yoga and surfing complement each other, both involving deep concentration, flexibility and balance.
(2) Results on resting blood pressure, serum lipids, vital capacity, flexibility, upper body strength, and vertical jump tests were comparable to values found for the sedentary population.
(3) This suggests that S1 is a flexible protein with at least two domains that can rotate independently.
(4) A more current view of science, the Probabilistic paradigm, encourages more complex models, which can be articulated as the more flexible maxims used with insight by the wise clinician.
(5) With improved monitoring, the use of smaller, more flexible endoscopes, and more experience, routine general anesthesia in children less than 3 years of age, as recommended in the past, may not be mandatory.
(6) Flexibility and integration of approaches may be advantageous and hypnosis, including regression and reframing, may be especially powerful in the treatment of phobics.
(7) The drug orientation and the DNA orientation (reflecting flexibility) are observed to vary differently and nonmonotonically with binding ratio, suggesting specific binding and varying site geometries.
(8) Extraction tools included flexible, telescoping sheaths advanced over the lead to dilate scar tissue and apply countertraction, deflection catheters, and wire basket snares.
(9) Flexibility is essential so that the appropriate technique or agent can be selected for a particular pediatric ICU patient.
(10) The flexible adaptation of psychosomatic aspects to the current needs of dermatologists was found most important.
(11) Lenses with inserted flexible open loops (e.g., Dubroff) have only been implanted in small series, but the results have been quite good.
(12) The presence of aspartic acid and asparagine residues in other conformations, such as those in partially denatured, conformationally flexible regions, may lead to more rapid succinimide formation and contribute to the degradation of the molecule.
(13) Eight alpha-helices behave as relatively rigid bodies and corner regions are more flexible, showing larger fluctuations.
(14) We interpret the high resistance of this protein to urea as reflecting a reduced flexibility of its structure at normal temperatures which should be correlated to the thermophilic origin of this protein.
(15) We argue that the power and flexibility of computer simulation as a technique for dealing with uncertainty and variability is especially appropriate in the case of HIV and AIDS.
(16) A one-way analysis of variance showed that there were no significant differences in flexibility of the five fixation constructs (P greater than .05).
