Here, we present a protocol for establishing a protein interactome based on close physical proximity to a target protein within live yeast cells. We describe steps for capturing both transient and stable binders by integrating a non-natural amino acid. We detail procedures for employing a site-directed method for labeling the surface that mediates protein associations and uncovers the binding sites on the interactors. Combined with mass spectrometry, our approach proves valuable in discovering binding partners and constructing a comprehensive protein-interaction network.

Mechanism of Sirtuin1-Mediated Deacetylation of p65-Mediated Ferroptosis of Hippocampal Neurons in Cerebral Injury after Cardiopulmonary Resuscitation in Rats.

Objective: Post-resuscitation brain injury is a common sequela after cardiac arrest (CA). Increasing sirtuin1 (SIRT1) has been involved in neuroprotection in oxygen-glucose deprivation (OGD) neurons, and we investigated its mechanism in post-cardiopulmonary resuscitation (CPR) rat brain injury by mediating p65 deacetylation modification to mediate hippocampal neuronal ferroptosis.
Methods: Sprague-Dawley rat CA/CPR model was established and treated with Ad-SIRT1 and Ad-GFP adenovirus vectors, or Erastin.

Objectives: This study evaluates the selective outcome reporting (SOR) in clinical trials on antibiotic use in third molar surgeries. It explores how SOR may bias results and affect systematic reviews, potentially leading to misinterpretations of intervention efficacy.
Materials And Methods: A search was conducted on "ClinicalTrials.

Background: NCRAD is a National Institute on Aging (NIA) cooperative grant, awarded to Indiana University since 1990, whose purpose is to serve as a biorepository for AD/ADRD researchers. With 74 participating across 150 unique institutions, NCRAD links specimens to clinical research data. NCRAD maintains over 2 million aliquots from more than 126,000 research participants spanning a wide range of AD/ADRD related phenotypes as well as healthy controls.

Background: Cerebral small vessel disease (CSVD), which includes cerebral amyloid angiopathy (CAA) and arteriolosclerosis, often co-occurs with Alzheimer's disease (AD) pathology. The medial temporal lobe (MTL) is susceptible to hosting multiple AD pathologies, such as neurofibrillary tangles (NFTs), amyloid-β plaques, phospho-Tar-DNA-Binding-Protein-43 (pTDP-43), as well as CSVD. Whether a causal relationship between these pathologies exists remains largely unknown, but one potential linking mechanism is the dysfunction of perivascular clearance.

There has been previous research linking AD to the missense variants ABI3-rs616338-T and PLCG2-rs72824905-G, and the altered expression of these genes has been shown to disrupt microglial function. In our understanding of AD risk and resilience, limited research has been conducted on how these variants affect microglial subtypes and states in AD.
