In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Input: Consider Input: Context: Sleep disturbances have been thought to augment pain. Sleep deprivation has been proven to produce hyperalgesic effects. It is still unclear whether these changes are truly specific to pain and not related to general changes in somatosensory functions. The aim of the present study was to evaluate the effect of total sleep deprivation on thermal pain thresholds (heat, cold) and pain complaints. Thermal detection thresholds (warmth, cold) were included as covariates to determine the contribution of somatosensory functions to changes in pain processing.', 'Twenty healthy volunteers were randomly assigned either to two nights of total sleep deprivation or to two nights of undisturbed night sleep. Sleep deprivation nights were separated by two days with normal night sleep. Heat and cold pain thresholds as well as warmth and cold detection thresholds were measured by use of a peltier thermode in the evening before and the morning after each deprivation or control night. Pain complaints were examined by use of a questionnaire in parallel.', 'During treatment nights, sleep deprivation produced a significant overnight decrease in heat pain thresholds. Cold pain thresholds tended to decrease also during sleep deprivation, whereas the warmth and cold detection thresholds remained unaffected. Accordingly, no substantial contributions of the changes in thermal detection thresholds to the changes in thermal pain thresholds were determined by regression analyses. Pain complaints were not induced by sleep deprivation.\Question: Does sleep deprivation affect thermal pain thresholds but not somatosensory thresholds in healthy volunteers?

Output: The present findings suggest that sleep deprivation produces hyperalgesic changes that cannot be explained by nonspecific alterations in somatosensory functions.


Input: Consider Input: Context: The quantity of the silver-stained nucleolar proteins (AgNOR proteins) measured in situ in cytohistologic preparations is related to the rapidity of cell proliferation. The term "AgNOR proteins" comprises several proteins. The relationship between the individual AgNOR protein amount and cell proliferating activity is not yet known. We studied the quantitative distribution of the individual AgNOR proteins, with specific attention to the two major AgNOR proteins, nucleolin and protein B23, in seven human cancer cell lines characterized by different cell doubling times.', 'The doubling time of cancer cells was measured by counting the asynchronously growing cells at regular time intervals. The AgNOR proteins were quantified in situ, after a specific one-step staining procedure, by computerized image analysis. For the quantitative evaluation of nucleolin and protein B23, two methods were followed. Nuclear proteins after separation by SDS-PAGE were transferred onto nitrocellulose membranes and were either: 1) stained by the silver staining procedure for AgNOR proteins or 2) treated with anti-nucleolin and anti-protein B23 mAb followed by reaction with secondary Ab linked to peroxidase and revealed by chemiluminescence and autoradiography. In both cases, measurement of individual AgNOR protein and nucleolin and protein B23 amount was carried out using computerized densitometric analysis.', 'Integrated density values of the silver-stained bands at 105 kDa (nucleolin) and 38 to 39 kDa (protein B23) represented, in all cell lines, more than 60% of the total silver-stained band value. A relationship was found between the densitometric values of silver-stained nucleolin and protein B23 and rapidity of cell proliferation (r = 0.85 and r = 0.86, respectively, p < 0.05). The values of nucleolin and protein B23 obtained using the Western blots were strictly related to the rapidity of cell proliferation (r = 0.93 and 0.96, respectively, p < 0.001). Finally, a good correlation was observed between the mean AgNOR protein area value, as defined in cytologic preparations in situ, and nucleolin and protein B23 amounts as evaluated in silver-stained nitrocellulose membranes (r = 0.92 and r = 0.90, respectively, p < 0.01) and in Western blots (r = 0.95 and r = 0.94, respectively, p < 0.001).\Question: Is the quantity of nucleolar proteins nucleolin and protein B23 related to cell doubling time in human cancer cells?

Output: These data indicate that the quantitative changes of AgNOR proteins observed in cytohistologic preparations in situ mainly reflect the quantitative changes of nucleolin and protein B23 and demonstrate that nucleolin and protein B23 amounts are inversely related to cell doubling time in human cancer cells.


Input: Consider Input: Context: The Epicoccum nigrum (EN) extract used in allergy disorders exhibits batch-to-batch variations in protein composition and allergenic potency. In this study, the allergens of EN grown in different media were investigated.', "EN was grown in five different nutrient media as stationary cultures at 25 degrees C for 5-23 days. The growth pattern was characterized by measuring dry weight, protein and carbohydrate content. The antigenic and allergenic content of EN extract was evaluated with EN-positive patients' sera and antibodies raised in rabbit.", "The growth of EN in Czapeck Dox medium yielded insufficient material, while Sabouraud's broth with yeast extract (SBY) gave maximum spore-mycelial mass and protein content. Potato dextrose broth (PDB) and potato dextrose agar (PDA) showed higher dry weight and protein in 7-9-day cultures. SDS-PAGE resolved 26, 22, and 21 protein bands in EN extracts from cultures of day-13 SBY, day-7 PDB, and day-9 PDA, respectively. IgE/IgG immunoblots showed more allergenic (25)/antigenic (25) bands in EN cultured in SBY than in the others. Specific IgE ELISA and intradermal tests showed EN extract from day-13 culture in SBY to be the most potent.\Question: Do allergens of Epicoccum nigrum grown in different media for quality source material?


Output: The day-13 culture of EN in SBY was the most potent and may be selected for preparing EN extracts for diagnosis of allergy and future studies.
