Accuracy of point-of-care ultrasound in diagnosing retained products of conception.

Introduction: Retained products of conception (RPOC) refers to residual intrauterine tissue in female patients after a recent birth, pregnancy termination, or miscarriage. Ultrasound is the primary diagnostic modality for RPOC, but the accuracy of point-of-care ultrasound (POCUS) has not been evaluated for this diagnosis. Our aim was to determine the test characteristics of POCUS in detecting RPOC, and to evaluate the management of RPOC in the Emergency Department.

Lentivirus-mediated gene therapy for Fabry disease: 5-year End-of-Study results from the Canadian FACTs trial.

Background: Fabry disease is an X-linked lysosomal storage disorder due to a deficiency of α-galactosidase A (α-gal A) activity. Our goal was to correct the enzyme deficiency in Fabry patients by transferring the cDNA for α-gal A into their CD34+ hematopoietic stem/progenitor cells (HSPCs). Overexpression of α-gal A leads to secretion of the hydrolase; which can be taken up and used by uncorrected bystander cells.

Assessing the preservation potential of successive hurricane overwash deposits in Florida, USA mangroves.

Geologic records of tropical cyclones (TCs) in low-energy, back-barrier environments are established by identifying marine sediments via their allochthonous biogeochemical signal. These records have the potential to reconstruct TC intensity and frequency through time. However, modern analog studies are needed to understand which biogeochemical indicators of overwash sediments are best preserved and how post-depositional changes may affect their preservation.

Patient-derived Induced Pluripotent Stem Cells as a Model to Study Frontotemporal Dementia Pathologies.

Unlabelled: The neurodegenerative disorder Frontotemporal Dementia (FTD) can be caused by a repeat expansion (GGGGCC; G4C2) in C9orf72. The function of wild-type C9orf72 and the mechanism by which the C9orf72-G4C2 mutation causes FTD, however, remain unresolved. Diverse disease models including human brain samples and differentiated neurons from patient-derived induced pluripotent stem cells (iPSCs) identified some hallmarks associated with FTD, but these models have limitations, including biopsies capturing only a static snapshot of dynamic processes and differentiated neurons being labor-intensive, costly, and post-mitotic.
