Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

A titrimetric method for determining total sulphur in mineral soils

, 1968
A rapid method for the determination of total sulphur in mineral soils is described. The various sulphur compounds in soil are first oxidised to sulphate by potassium dichromate in phosphoric acid, and the sulphate thus formed is then reduced to sulphur ...

Stage 1 Round-Robin Report: On the Use of Total Focusing Method for Sizing Flaws in Assessing Probability of Detection

e-Journal of Nondestructive Testing, 2023
Reliability of non-destructive (NDT) procedures is usually assessed using probability of detection (POD). However, the reliability of the POD is rarely questioned. A POD usually produces a curve that relates the size of a defect to the likelihood that

Improvement of the total focusing method using an inverse problem approach

, 2017
International audienceImaging using the total focusing method (TFM) is a popular tool in nondestructive evaluation and it becomes a standard. From full matrix capture, this method consists in focusing at each point of a defined reconstruction zone. It is

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...

Self-adaptive transcranial ultrasound imaging using an effective skull model: experimental evaluation on a human skull at 3.15 MHz

Acta Acustica
Introduction. Transcranial ultrasound imaging is hindered by skull-induced aberrations that degrade focusing and image contrast. Existing correction methods typically rely on external imaging or detailed acoustic models, limiting their applicability in ...

Pediatric Idiopathic Multicentric Castleman Disease Is Often Severe But Responsive to Siltuximab

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Idiopathic multicentric Castleman disease (iMCD) is a potentially fatal immunologic disorder marked by widespread lymphadenopathy and inflammation. Siltuximab, an interleukin‐6 (IL‐6) inhibitor, is the only FDA‐approved treatment for adult patients with iMCD.

An adapted version of the element-wise weighted total least squares method for applications in chemometrics

, 2007
The Maximum Likelihood PCA (MLPCA) method has been devised in chemometrics as a generalization of the well-known PCA method in order to derive consistent estimators in the presence of errors with known error distribution.
