Basic Science and Pathogenesis.

Background: The bi-directional autophagy and inflammation network becomes progressively dysregulated with age, with systemic inflammation as a biomarker of this dysregulation including in Alzheimer's Disease (AD). We hypothesize that interventions which target the shared feature of systemic inflammation in the biology of aging and AD, via regulation of the autophagy-inflammation network, will prevent the conversion to disease pathogenesis in AD as well as improve healthspan and longevity in aging populations. While previous studies report benefits of mTOR inhibition including rapamycin in transgenic mouse models of familial AD, the present studies aim to evaluate this pathway in a model of sporadic, late onset AD (LOAD) and test the contribution of AMP-activated protein kinase (AMPK) as a critical regulator of the mTOR pathway.

Stabilizing complex-Langevin field-theoretic simulations for block copolymer melts.

Complex-Langevin field-theoretic simulations (CL-FTSs) provide an approximation-free method of calculating fluctuation corrections to the self-consistent field theory (SCFT) of block copolymer melts. However, the complex fields are prone to the formation of hot spots, which causes the method to fail. This problem has been attributed to an invariance under complex translations, which allows the system to drift away from the real-valued saddle-point of SCFT.

The International Bathymetric Chart of the Arctic Ocean Version 5.0.

Knowledge about seafloor depth, or bathymetry, is crucial for various marine activities, including scientific research, offshore industry, safety of navigation, and ocean exploration. Mapping the central Arctic Ocean is challenging due to the presence of perennial sea ice, which limits data collection to icebreakers, submarines, and drifting ice stations. The International Bathymetric Chart of the Arctic Ocean (IBCAO) was initiated in 1997 with the goal of updating the Arctic Ocean bathymetric portrayal.

Number of Doses of Systemic Antibiotic Prophylaxis May Be Reduced in Cemented Primary Knee Arthroplasty Irrespective of Use of Antibiotic in the Cement: A Multiregistry-Based Meta-Analysis.

Background: The use of systemic antibiotic prophylaxis (SAP) and antibiotic-loaded bone cement (ALBC) is the accepted practice to reduce the risk of periprosthetic joint infection (PJI) in primary total knee arthroplasty (pTKA). However, practice varies internationally. This study's primary aim was to compare the risk of PJI revision after pTKA with ALBC + SAP vs.

Anatomic Outcomes With Faricimab vs. Aflibercept in the Head-to-Head Dosing Phase of the TENAYA/LUCERNE Trials in Neovascular AMD.

Purpose: To compare early anatomic outcomes following treatment with faricimab vs. aflibercept in a pooled analysis of the head-to-head dosing phase of the TENAYA/LUCERNE trials in neovascular age-related macular degeneration (nAMD).

Design: TENAYA/LUCERNE (NCT03823287/NCT03823300) were identical, randomized, double-masked, active comparator-controlled phase 3 noninferiority trials.
