Factors influencing the adequacy of determining hemispheric language lateralization in presurgical epilepsy patients using functional transcranial Doppler sonography (fTCD).

As the adequacy of determining hemispheric language lateralization (HLL) is of special importance for the planning of epilepsy surgery, this study aimed to identify predictive factors for receiving inconclusive HLL results using functional transcranial Doppler sonography (fTCD). Data from 495 epilepsy patients who received fTCD in a standardized fashion was analyzed retrospectively. HLL was left-sided in 324 patients (65.

Isolation of lymph shows dysregulation of STAT3 and CREB pathways in the spleen and liver during leukemia development in a rat model.

Background And Aims: Acute myeloid leukemia (AML) is a heterogeneous malignant condition characterized by massive infiltration of poorly differentiated white blood cells in the blood stream, bone marrow, and extramedullary sites. During leukemic development, hepatosplenomegaly is expected to occur because large blood volumes are continuously filtered through these organs. We asked whether infiltration of leukemic blasts initiated a response that could be detected in the interstitial fluid phase of the spleen and liver.

Comparative Study of Friction and Wear Performance of PEK, PEEK and PEKK Binders in Tribological Coatings.

Tribological coatings are widely used in industry, particularly when the conventional oil lubrication of sliding surfaces has to be replaced by maintenance-free contacts. This work studies the tribological performance of waterborne tribological coatings based on three binders of the polyaryletherketone (PAEK) family: polyetherketone (PEK), PEEK, and polyetherketoneketone (PEKK). Even though PEEK is a well-known commercial solution for this type of tribological coatings, PEK and PEKK have never been studied in such a context.

Characteristics of Electric Scooter and Bicycle Injuries After Introduction of Electric Scooter Rentals in Oslo, Norway.

Importance: When society introduces and accepts new transportation modes, it is important to map risks and benefits.

Objective: To compare electric scooter (e-scooter) and bicycle injuries.

Design, Setting, And Participants: This cohort study is based on prospectively collected data on Norwegian patients who sustained e-scooter or bicycle injuries and presented to an emergency department affiliated with Oslo University Hospital between January 1, 2019, and March 31, 2020.
