Ongoing loss of viable neurons for weeks after mild perinatal hypoxia-ischemia.

Unlabelled: Mild hypoxic-ischemic encephalopathy is common in neonates with no evidence-based therapies, and 30-40% of patients experience adverse outcomes. The nature and progression of mild injury is poorly understood. Thus, we studied the evolution of mild perinatal brain injury using longitudinal two-photon imaging of transgenic fluorescent proteins as a novel readout of neuronal viability and activity at cellular resolution.

Understanding the role of environment in associative learning of nicotine-induced place preference conditioning in zebrafish.

Environmental enrichment (EE) is a well-known strategy in animal behavior to improve the welfare and health of animals in captivity. EE provides animals with stimulating and engaging environments that promote natural behaviors, cognitive stimulation and stress reduction. EE turns out to be an important strategy to increase the validity and reproducibility of behavioral data.

Preferential adsorption of noble gases in zeolitic tuff with variable saturation: A modeling study of counter-intuitive diffusive-adsorptive behavior.

Noble gas transport through geologic media has important applications in the prediction and characterization of measured gas signatures related to underground nuclear explosions (UNEs). Retarding processes such as adsorption can cause significant species fractionation of radionuclide gases, which has implications for measured and predicted signatures used to distinguish radioxenon originating from civilian nuclear facilities or from UNEs. Accounting for the effects of variable water saturation in geologic media on tracer transport is one of the most challenging aspects of modeling gas transport because there is no unifying relationship for the associated tortuosity changes between different rock types, and reactive transport processes such as adsorption that are affected by the presence of water likewise behave differently between gas species.

Efficacy of modified natural cycle vs. hormone replacement therapy in oocyte donation for recipients of advanced maternal age: a retrospective study.

Purpose: To compare the efficacy of modified natural cycle (mNC) preparation versus hormone replacement therapy (HRT) for endometrial preparation in recipients of donated oocytes, specifically focusing on pregnancy rates in women of advanced maternal age.

Methods: Retrospective multicenter analysis conducted between 2021 and 2024. It includes 220 cycles of fresh single blastocyst transfers resulting from oocyte donation.

Effect of GFRP Stirrup Confinement on the Bond Strength of GFRP-RC Beams.

The current provisions for development length in the ACI 440.11 code disregard the confinement effect provided by stirrups on the bond strength of longitudinal bars and require splice lengths that pose implementation challenges. Given the significant improvement in GFRP material properties, this study investigated the bond strength of sand-coated GFRP bars and proposed a new factor to include the effect of stirrup confinement on the bond-strength provisions.
