Cluster of differentiation 38 (CD38) is an ecto-enzyme expressed primarily on immune cells that metabolize nicotinamide adenine dinucleotide (NAD+) to adenosine diphosphate ribose or cyclic ADP-ribose and nicotinamide. Other substrates of CD38 include nicotinamide adenine dinucleotide phosphate and nicotinamide mononucleotide, a critical NAD+ precursor in the salvage pathway. NAD+ is an important coenzyme involved in several metabolic pathways and is a required cofactor for the function of sirtuins (SIRTs) and poly (adenosine diphosphate-ribose) polymerases.

Purpose: To evaluate the safety, activity, and emergence of FLT3-kinase domain (KD) mutations with combination therapy of crenolanib and sorafenib in acute myeloid leukemia (AML) with FLT3-internal tandem duplication (ITD).

Patients And Methods: After in vitro and xenograft efficacy studies using AML cell lines that have FLT3-ITD with or without FLT3-KD mutation, a pilot study was performed with crenolanib (67 mg/m2/dose, three times per day on days 1-28) and two dose levels of sorafenib (150 and 200 mg/m2/day on days 8-28) in 9 pediatric patients with refractory/relapsed FLT3-ITD-positive AML. Pharmacokinetic, pharmacodynamic, and FLT3-KD mutation analysis were done in both preclinical and clinical studies.

Objective: Identify factors associated with presence and extension of spinal and sacroiliac joints (SIJ)-MRI lesions suggestive of axial spondyloarthritis (axSpA) in a population-based cohort (Study of Health in Pomerania) aged <45 years.

Methods: Spinal (sagittal T1/T2) and SIJ (semicoronal STIR sequences) MRIs were evaluated by two trained blinded readers. The presence (yes/no) and extension (Berlin MRI Score) of bone marrow oedema (BME) were captured.

Objective: To investigate the frequency of bone marrow oedema (BME) and fatty lesions (FL) suggestive of axial spondyloarthritis (axSpA) on MRI of the spine and sacroiliac joints (SIJ) in a general population sample.

Methods: As part of a community-based cohort project (Study of Health in Pomerania), volunteers underwent spinal (sagittal T1/T2) and SIJ (semicoronal short tau inversion recovery) MRI examinations. Two calibrated readers evaluated the images to detect BME in SIJ and vertebral corners (VC) and FL in VC suggestive of axSpA using Assessment of SpondyloArthritis international Society definitions.

Fms-like tyrosine kinase 3 (FLT3) internal tandem duplication (ITD) mutations, common in pediatric acute myeloid leukemia (AML), associate with early relapse and poor prognosis. Past studies have suggested additional cooperative mutations are required for leukemogenesis in FLT3-ITD+ AML. Using RNA sequencing and a next-generation targeted gene panel, we broadly characterize the co-occurring genomic alterations in pediatric cytogenetically normal (CN) FLT3-ITD+ AML to gain a deeper understanding of the clonal patterns and heterogeneity at diagnosis and relapse.

Objective: To describe the prevalence and characteristics of comorbidities in persons with rare epilepsies.

Study Design: Persons with rare epilepsies and caregivers of those affected were recruited through the Epilepsy Foundation and more than 30 rare epilepsy advocacy organizations affiliated with the Rare Epilepsy Network (REN). A web-based survey was conducted using a questionnaire consisting of core sections to collect data from affected persons on various aspects, including comorbidities.

Context: Invasive fungal infections are an important cause of morbidity and mortality among immunocompromised patients.

Objective: To design and evaluate a multiplexed assay aimed at quantitative detection and differentiation of the 5 molds that are most commonly responsible for pulmonary infections.

Design: Using labeled primer polymerase chain reaction chemistry, an assay was designed to target the 5.

Cross-sectional surveys of human blood and breast milk show increasing concentrations of polybrominated diphenyl ethers (PBDEs) that parallel the expanded use in consumer products, but longitudinal studies are lacking. We compared levels of major BDE congeners in archived 1994-1995 blood samples collected from a cohort of frequent and infrequent Great Lakes fish consumers with levels in the blood collected from the same individuals in 2001-2003 and 2004-2005. In mixed linear regression models controlling for multiple measurements per individual and covariates, statistically significant increases were seen from 1994-1995 to 2001-2003 for ∑PBDEs and BDE-47, 99, and 153 and from 1994-1995 to 2004-2005 for ∑PBDEs and BDE-99, 100, and 153, but ∑PBDEs and BDE congeners did not change significantly between 2001-2003 and 2004-2005.

A direct role of carbon monoxide (CO), an effector-signaling molecule during heme oxygenase-1 (HO-1) catalysis of heme, in the protection against hepatic ischemia/reperfusion (I/R) injury needs to be established. This study was designed to determine the effects and downstream mechanisms of CO on cold I/R injury in a clinically relevant isolated perfusion rat liver model. After 24 hours of cold storage, rat livers perfused ex vivo for 2 hours with blood supplemented with CO (300 parts per million) showed significantly decreased portal venous resistance and increased bile production, as compared with control livers perfused with blood devoid of CO.

A group of 79 renal transplant patients undergoing acute rejection episodes were treated with Thymoglobulin (rabbit anti-thymocyte globulin), 1.5 mg/kg/day for 6-14 days as part of a double-blinded trial comparing the efficacy of Thymoglobulin and Atgam (horse anti-thymocyte globulin). Serial serum samples from the patients were tested to determine the level of Thymoglobulin (i.

The endogenous aliphatic alcohols ethanol, n-propanol, n-butanol, isobutanol and isopentanol in serum and urine were measured by gas chromatography-mass fragmentography. Whereas for the higher-molecular-weight alcohols extraction with dichloromethane is used, ethanol is determined by direct injection of serum and urine. When zero is assigned to all values below the detection limits of the procedures (0.
