Association of maternal depression and hypothyroidism with infant gastroschisis: a population-based cohort study in Canada.

Gastroschisis has increased globally over recent decades, and this increase has not been explained by identified risk factors. We conducted a population-based study of infants born in Canada, 2004-2020. We used "winter" months (i.

Typical dynamic electrocardiographic changes in Takotsubo syndrome.

Aims: Negative T waves and QTc prolongation often occur in patients with Takotsubo syndrome. Description of typical electrocardiographic changes could be a diagnosis element of this syndrome. This study aimed to clarify on the one hand the more preciously possible the typical electrocardiographic changes, and on the other hand, the timing of occurrence of these abnormalities compared to the trigger occurrence, the symptoms onset and the hospital admission.

Differential Nanoparticle Sequestration by Macrophages and Scavenger Endothelial Cells Visualized in Real-Time and at Ultrastructural Resolution.

Despite the common knowledge that the reticuloendothelial system is largely responsible for blood clearance of systemically administered nanoparticles, the sequestration mechanism remains a "black box". Using transgenic zebrafish embryos with cell type-specific fluorescent reporters and fluorescently labeled model nanoparticles (70 nm SiO), we here demonstrate simultaneous three-color imaging of intravenously injected nanoparticles, macrophages, and scavenger endothelial cells (SECs). The trafficking processes were further revealed at ultrastructural resolution by transmission electron microscopy.

Ozone differential absorption lidar algorithm intercomparison.

An intercomparison of ozone differential absorption lidar algorithms was performed in 1996 within the framework of the Network for the Detection of Stratospheric Changes (NDSC) lidar working group. The objective of this research was mainly to test the differentiating techniques used by the various lidar teams involved in the NDSC for the calculation of the ozone number density from the lidar signals. The exercise consisted of processing synthetic lidar signals computed from simple Rayleigh scattering and three initial ozone profiles.

Predictive values of age and the Glasgow Coma Scale in traumatic brain injury patients treated with decompressive craniectomy.

Background: The use of decompressive craniectomy (DC) as an aggressive therapy for traumatic brain injury (TBI) has gained renewed interest. While age and the Glasgow Coma Scale (GCS) are frequently correlated with outcome in TBI, their prognostic values after decompressive craniectomy are ill-defined.

Methods: We retrospectively reviewed data from 103 TBI patients treated with DC from 2001 to 2003.
