Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Input: Consider Input: The aim of this study was to investigate the suppressive capacity of CD25(+) regulatory T cells on birch allergen-induced T-cell responses during the first birch pollen season after initiation of specific immunotherapy (SIT).', 'CD25(pos) and CD25(neg) T cells were purified from blood of birch-allergic SIT patients and birch-allergic controls, stimulated with birch pollen extract, and analyzed for T-cell proliferation and production of interferon gamma (IFN-gamma), interleukin (IL)-5 and IL-10.', 'We show that allergen-induced proliferation and IFN-gamma production were suppressed equally well by CD25(pos) T cells from SIT patients and controls, while the IL-5 production was not suppressed by either of the groups. IL-10 levels were higher in SIT patients relative to controls only when CD25(neg) and CD25(pos) were cultured together. Furthermore, neither FOXP3 levels nor proportions of CD25(high) T cells were enhanced in SIT patients compared to allergic controls.

Input: Consider Input: This study aims to evaluate the relationship between serum thymus and activation-regulated chemokine (TARC) levels with various clinicopathological conditions in patients with drug eruptions. The value of TARC in diagnosing drug-induced hypersensitivity syndrome (DIHS) was also examined.', 'Study participants included 84 patients who presented with generalized eruptions suspected to be drug-related, including DIHS, Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), maculopapular exanthema (MPE), erythema multiforme (EM), erythroderma, and toxicoderma. The correlation coefficients between serum TARC levels and clinical parameters in peripheral blood samples were calculated.', 'Serum TARC levels in patients with DIHS were higher than those found in patients with SJS/TEN, MPE, EM, and toxicoderma. TARC levels had 100% sensitivity and 92.3% specificity in diagnosing DIHS, with a threshold value of 13,900pg/mL. Serum TARC levels positively correlated with age, white blood cell (WBC) count, neutrophil count, eosinophil count, monocyte count, atypical lymphocyte (Aty-ly) count, serum blood urea nitrogen (BUN) levels, and creatinine (Cr) levels. It negatively correlated with serum total protein (TP), albumin (Alb), and estimated glomerular filtration rate (eGFR). Among these clinical parameters, blood eosinophil counts were most strongly correlated with serum TARC levels, with a correlation coefficient of 0.53.

Input: Consider Input: 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.
