esters to find a highly active and specific substrate for LAL in DBS. dbs 152-155 lipase A, lysosomal acid type Homo sapiens 145-148 29339442-6 2018 RESULTS: The ester formed between palmitic acid and 4-propyl-8-methyl-7-hydroxycoumarin (P-PMHC) was found to be >98% selective for LAL in DBS based on the sensitivity of its activity to the LAL-specific inactivator Lalistat-2 and the fact that the activity was close to zero using DBS from patients previously shown to be LAL-deficient. dbs 142-145 lipase A, lysosomal acid type Homo sapiens 135-138 29339442-6 2018 RESULTS: The ester formed between palmitic acid and 4-propyl-8-methyl-7-hydroxycoumarin (P-PMHC) was found to be >98% selective for LAL in DBS based on the sensitivity of its activity to the LAL-specific inactivator Lalistat-2 and the fact that the activity was close to zero using DBS from patients previously shown to be LAL-deficient. dbs 285-288 lipase A, lysosomal acid type Homo sapiens 135-138 29339442-9 2018 CONCLUSIONS: The new assay can measure LAL in DBS with a single measurement compared with the previous method involving 2 assays done in parallel. dbs 46-49 lipase A, lysosomal acid type Homo sapiens 39-42 31505261-3 2019 METHODS: LAL activity was measured (i) on dried blood spots (DBS) from NAFLD patients and dyslipidemic subjects without fatty liver and (ii) on liver biopsies from NAFLD patients. dbs 61-64 lipase A, lysosomal acid type Homo sapiens 9-12 31505261-6 2019 LAL activity measured in liver biopsies from NAFLD patients was highly correlated to that measured on DBS and was independent of LAL expression in the liver. dbs 102-105 lipase A, lysosomal acid type Homo sapiens 0-3 31505261-7 2019 In a fully adjusted model, LAL activity on DBS was associated only with platelets and, when normalized by platelet count, it did not differ according to fibrosis stage. dbs 43-46 lipase A, lysosomal acid type Homo sapiens 27-30 24295952-3 2014 Recently, Hamilton used a fluorometric enzyme assay with 4-MU derivatives to measure the LAL activity in DBS. dbs 105-108 lipase A, lysosomal acid type Homo sapiens 89-92 28532785-6 2017 With the increase in DBS LAL testing since the original publication of this method, a need to optimise assay performance has been identified. dbs 21-24 lipase A, lysosomal acid type Homo sapiens 25-28 28238812-1 2017 BACKGROUND: We aimed to evaluate the influence of white blood cell (WBC) and platelet (PLT) counts on dried blood spot (DBS)-determined lysosomal acid lipase (LAL) activity in a large group of healthy subjects. dbs 120-123 lipase A, lysosomal acid type Homo sapiens 136-157 28238812-1 2017 BACKGROUND: We aimed to evaluate the influence of white blood cell (WBC) and platelet (PLT) counts on dried blood spot (DBS)-determined lysosomal acid lipase (LAL) activity in a large group of healthy subjects. dbs 120-123 lipase A, lysosomal acid type Homo sapiens 159-162 28238812-3 2017 Complete clinical biochemistry and LAL activity in DBS were determined. dbs 51-54 lipase A, lysosomal acid type Homo sapiens 35-38 28238812-5 2017 Univariate and multivariate analyses to DBS-LAL activity were performed. dbs 40-43 lipase A, lysosomal acid type Homo sapiens 44-47 28238812-8 2017 However, LAL activity in DBS correlated more strongly with that in PLTs (r=0.65, p<0.001) than with that in WBCs (r=0.49, p<0.01). dbs 25-28 lipase A, lysosomal acid type Homo sapiens 9-12 28238812-9 2017 Consistently, in the multivariate model, DBS-LAL activity was independently associated only with PLT count (beta=0.39, p<0.001). dbs 41-44 lipase A, lysosomal acid type Homo sapiens 45-48 28238812-10 2017 CONCLUSIONS: PLT number may impact on the result of the DBS-LAL test, and a consideration of PLT count is recommended before interpreting LAL activity in DBS. dbs 56-59 lipase A, lysosomal acid type Homo sapiens 60-63 28238812-10 2017 CONCLUSIONS: PLT number may impact on the result of the DBS-LAL test, and a consideration of PLT count is recommended before interpreting LAL activity in DBS. dbs 154-157 lipase A, lysosomal acid type Homo sapiens 138-141 28587063-5 2017 For each patient, LAL activity was determined on peripheral dried blood spots (DBS) and correlated with clinical and laboratory data. dbs 79-82 lipase A, lysosomal acid type Homo sapiens 18-21 28587063-9 2017 LAL activity is also correlated with platelet and white blood cell count, suggesting an analytic interference of portal-hypertension-induced pancytopenia on DBS-determined LAL activity. dbs 157-160 lipase A, lysosomal acid type Homo sapiens 0-3 28587063-9 2017 LAL activity is also correlated with platelet and white blood cell count, suggesting an analytic interference of portal-hypertension-induced pancytopenia on DBS-determined LAL activity. dbs 157-160 lipase A, lysosomal acid type Homo sapiens 172-175 24295952-7 2014 The LAL activity in DBS was measured in 51 normal controls, seven obligate carriers and seven patients with CESD. dbs 20-23 lipase A, lysosomal acid type Homo sapiens 4-7 24295952-8 2014 The average LAL activities +- SD in the DBS from the normal, obligate carriers and CESD patients were 0.68 +- 0.2 (range: 0.3-1.08), 0.21 +- 0.1 (range: 0.11-0.41) and 0.02 +- 0.02 (range: 0-0.06) nmol/punch/h, respectively. dbs 40-43 lipase A, lysosomal acid type Homo sapiens 12-15
