[EX Q]: Context: Alkaline/vacuolar serine proteases comprise a major group of pan-fungal allergens from several prevalent airborne fungal species. It is of importance to characterize antigenic determinant(s) recognized by monoclonal antibodies against these major allergens.', 'The antigenic determinant of fungal serine proteases recognized by a monoclonal antibody, FUM20, was analyzed by dot immunoassay of synthetic peptides immobilized on cellulose membrane. Results obtained were confirmed by wild-type recombinant protease and its mutants. The epitopes were mapped to the structure of serine proteases by molecular modeling.', 'A linear epitope encompassing 9 amino acids from Pen ch 18 ((6)EKNAPWGLA(14)) binds FUM20. The corresponding peptide ((5)AKGAPWGLA(13)) from Rho m 2 also binds FUM20. Substitution of K6, P9 or W10 with alanine in this peptide resulted in drastic loss of FUM20 binding. Rho m 2 mutants with single K6A, P9A, P9G, W10A or W10F substitute showed negative immunoblot reactivity against FUM20. However, the Rho m 2 K6R mutant can bind FUM20. Three-dimensional structural models of the FUM20 antigenic determinants on serine proteases were constructed. The lysine residue critical for FUM20 interaction is on the surface of the proteases and solvent accessible. The critical core residue proline is located at the beginning of an alpha-helix.
Answer: The lysine, proline and tryptophan residues located on the N-terminal region of fungal serine proteases are critical core amino acid residues recognized by FUM20, a monoclonal antibody against serine protease pan-fungal allergens. These findings advance our understanding of the antigenic structures responsible for the antigenicity of serine protease allergens.

[EX Q]: Context: Is weight-training exercise intervention harmful to women with or at risk of breast cancer-related lymphoedema?', 'Systematic review with meta-analysis of randomised trials.', 'Women with or at risk of breast cancer-related lymphoedema.', 'Progressive weight-training exercise.', 'The primary outcomes were severity (volume difference) and incidence of arm lymphoedema. Secondary outcomes included muscle strength of the upper and lower limbs, quality of life and body mass index.', 'Eleven studies from eight trials involving 1091 women were included. Weight-training exercise of low to moderate intensity with relatively slow progression significantly improved the upper limb strength (SMD 0.93, 95% CI 0.73 to 1.12) and lower limb strength (SMD 0.75, 95% CI 0.47 to 1.04) without increasing the arm volume (SMD -0.09, 95% CI -0.23 to 0.05) or incidence of breast cancer-related lymphoedema (RR 0.77, 95% CI 0.52 to 1.15). No significant effects were noted for body mass index (SMD -0.10, 95% -0.31 to 0.11). Some aspects of quality of life may improve with weight training. PARTICIPANTS in all trials used pressure garments and received supervision; no trials used high-intensity weight training.
Answer: Weight training appears to be safe and beneficial in improving limb strength and physical components of quality of life in women with or at risk of lymphoedema. Pressure garments, supervision and limiting the intensity of the weight training may each be important, but this could not be confirmed with this review.

[EX Q]: Context: To evaluate the relationship between serum interleukin (IL)-6 and cachexia in patients with prostate cancer.', 'Serum levels of IL-6, total protein, albumin, total cholesterol, and hemoglobin concentration were determined in 164 blood samples from patients with prostate cancer. The body mass index and performance status were also determined.', 'The serum total protein, albumin, and cholesterol levels, hemoglobin levels, and body mass index of the patients whose serum IL-6 level was 7 pg/mL or greater were significantly lower (P <0.05) than the corresponding values in patients with a serum IL-6 level of less than 7 pg/mL. The serum IL-6 level of patients with a serum albumin level of less than 3.5 g/dL, serum total protein level of less than 7.0 g/dL, serum total cholesterol level of less than 180 mg/dL, hemoglobin level of less than 11.0 g/dL, and body mass index of less than 21 kg/m2 were significantly greater (P <0.05) than the values in their respective counterparts. A significant correlation was found between the elevation of serum IL-6 and performance status (P <0.05). The mortality rate of patients with greater serum IL-6 levels was significantly greater than that of those with lower serum IL-6 levels in patients with untreated disease, patients in remission, and patients with relapse (all P <0.05).
Answer: These findings suggest that IL-6 may be one of the factors contributing to the complex syndrome of cachexia in patients with prostate cancer (all P <0.05).
