ACTIVITIES OF L-ASPARAGINASE FROM CICER COTYLEDONS UNDER DIFFERENT TREATMENTS [PDF]

Journal of Plant Production, 2009
L-asparaginase (EC 3.5.1.1) activity is measured in Cicer arietinum cotyledons. Studying the relation between germination time of Cicer and L-asparaginase activity throughout 7 days revealed that L-asparaginase activity increased gradually up to the 5th ...

Admixture Mapping Reveals Candidate Regions for Methotrexate Neurotoxicity Susceptibility: A Reducing Disparities in Acute Leukemia Consortium Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Neurotoxicity is a rare, often dose‐limiting adverse effect of methotrexate (MTX) therapy that disproportionally affects Latino children. Factors contributing to the observed disparity are not well understood. This study leveraged admixture mapping to identify genetic regions associated with MTX‐related neurotoxicity susceptibility ...

Secretory Phospholipase A2 in Patients With Sickle Cell Disease Hospitalized for Vaso‐Occlusive Pain Episodes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Secretory phospholipase A2 (sPLA2) is an inflammatory mediator linked to acute chest syndrome (ACS) in sickle cell disease (SCD), a serious complication that can develop during an acute vaso‐occlusive pain episode (VOE). Plasma sPLA2 levels have been proposed as a potential biomarker for predicting ACS onset.
