Intraoperative Aberrometry versus Preoperative Biometry for Intraocular Lens Power Calculations: A Report by the American Academy of Ophthalmology.

Purpose: To evaluate the published literature to compare intraoperative aberrometry (IA) with preoperative biometry-based formulas with respect to intraocular lens (IOL) power calculation accuracy for various clinical scenarios.

Methods: Literature searches in the PubMed database conducted in August 2022, July 2023, and February 2024 identified 157, 18, and 6 citations, respectively. These were reviewed in abstract form, and 61 articles were selected for full-text review.

The role of microglia in neuronal and cognitive function during high altitude acclimatization.

Due to their interactions with the neurovasculature, microglia are implicated in maladaptive responses to hypobaric hypoxia at high altitude (HA). To explore these interactions at HA, pharmacological depletion of microglia with the colony-stimulating factor-1 receptor inhibitor, PLX5622, was employed in male C57BL/6J mice maintained at HA or sea level (SL) for 3-weeks, followed by assessment of ex-vivo hippocampal long-term potentiation (LTP), fear memory recall and microglial dynamics/physiology. Our findings revealed that microglia depletion decreased LTP and reduced glucose levels by 25% at SL but did not affect fear memory recall.

A designed ankyrin-repeat protein that targets Parkinson's disease-associated LRRK2.

Leucine rich repeat kinase 2 (LRRK2) is a large multidomain protein containing two catalytic domains, a kinase and a GTPase, as well as protein interactions domains, including a WD40 domain. The association of increased LRRK2 kinase activity with both the familial and sporadic forms of Parkinson's disease has led to an intense interest in determining its cellular function. However, small molecule probes that can bind to LRRK2 and report on or affect its cellular activity are needed.

Helping Educational Leaders Mobilize Evidence (HELM): The iterative redesign of the Leadership and Organizational Change for Implementation (LOCI) intervention for use in schools.

Background: Few "intervention agnostic" strategies have been developed that can be applied to the broad array of evidence-based practices (EBPs) in schools. This paper describes two studies that reflect the initial iterative redesign phases of an effective leadership-focused implementation strategy-Leadership and Organizational Change for Implementation (LOCI)-to ensure its acceptability, feasibility, contextual appropriateness, and usability when used in elementary schools. Our redesigned strategy-Helping Educational Leaders Mobilize Evidence (HELM)-is designed to improve principals' use of strategic implementation leadership to support the adoption and high-fidelity delivery of a universal EBP to improve student outcomes.

Proteomic changes in the hippocampus of large mammals after total-body low dose radiation.

There is a growing interest in low dose radiation (LDR) to counteract neurodegeneration. However, LDR effects on normal brain have not been completely explored yet. Recent analyses showed that LDR exposure to normal brain tissue causes expression level changes of different proteins including neurodegeneration-associated proteins.
