AI Article Synopsis
- The study assessed the effectiveness of using volume and total nucleated cell (TNC) count for selecting cord blood units for transplantation.
- TNC count was found to be the most reliable indicator for identifying cord blood units with at least 2 million CD34+ cells, achieving a notable area under the ROC curve of 0.828.
- Combining TNC with other parameters didn't improve selection efficiency, but a TNC count of 8 × 10(8) or more was sufficient for patients weighing 10 kg or less.
Article Abstract
The objective of the study was to evaluate the current standard practice of using volume and total nucleated cell (TNC) count for the selection of cord blood (CB) units for cryopreservation and further transplantation. Data on 794 CB units whose CD34+ cell content was determined by flow cytometry were analyzed by using a receiver operating characteristic (ROC) curve model to validate the performance of volume and TNC count for the selection of CB units with grafting purposes. The TNC count was the best parameter to identify CB units having 2 × 10(6) or more CD34+ cells, with an area under the ROC curve of 0.828 (95% confidence interval, 0.800-0.856; P < .01) and an efficiency of 75.4%. Combination of parameters (TNC/mononuclear cells [MNCs], efficiency 74.7%; TNC/volume, efficiency 68.9%; and volume/MNCs, efficiency 68.3%) did not lead to improvement in CB selection. All CB units having a TNC count of 8 × 10(8) or more had the required CD34+ cell dose for patients weighing 10 kg or less.

Background: Evidence from preclinical studies in small and large animal models has shown neuroprotective effects of intravenous administration of umbilical cord blood derived cells (UCBCs). This study aimed to evaluate the feasibility of umbilical cord blood (UCB) collection, extraction of UCBCs, and subsequent safety of intravenous autologous administration of UCBCs in extremely preterm infants (born <28 weeks gestation).

Intracellular calcium (Ca) is involved in a plethora of cell signalling processes and physiological functions. Increases in Ca concentration are bona fide biomarkers of neuronal activity, reflecting the spike count, timing, frequency, and the intensity of synaptic input. The development of genetically encoded calcium indicators (GECIs) was a significant advancement in modern neuroscience that enabled real-time visualisation of neuronal activity at single-cell resolution.

Computed tomographic (CT) coronary artery angiography with calcium scoring is crucial in suspecting coronary artery disease (CAD). The routine protocol for CAD radiological investigation involves a precontrast series for calcium scoring and a postcontrast series for investigating structural changes in coronary arteries. This review intends to investigate the feasibility of virtual noncontrast images to replace the true noncontrast (TNC) images in coronary artery calcium scoring to decrease the radiation dose.

: Virtual non-contrast (VNC) series reconstructed from contrast-enhanced cardiac scans acquired with photon counting detector CT (PCD-CT) systems have the potential to replace true non-contrast (TNC) series. However, a quantitative comparison of the image characteristics of TNC and VNC data is necessary to determine to what extent they are interchangeable. This work quantitatively evaluates the image similarity between VNC and TNC reconstructions by measuring the stability of multi-class radiomics features extracted in intra-patient TNC and VNC reconstructions.
