Drug Development.

Background: Non-human primates (NHP) serve as an important bridge for testing therapeutic agents that have been previously shown to be effective in transgenic mouse models. Our earlier published data using an NHP model of sporadic AD-related pathology that develops abundant cerebral amyloid angiopathy (CAA), squirrel monkeys (SQMs), indicates that chronic treatment with TLR9 agonist, class B CpG ODN, safely ameliorates CAA while promoting cognitive benefits. In the present study, we intended to delineate alterations in brain metabolome induced by chronic CpG ODN administration in order to provide further insight into CpG ODN immunomodulatory capabilities.

Clinicopathologic and genomic features associated with brain metastasis after resection of lung adenocarcinoma.

Objective: To identify clinicopathologic and genomic features associated with brain metastasis after resection of lung adenocarcinoma (LUAD) and to evaluate survival after brain metastasis.

Methods: Patients who underwent complete resection of stage I-IIIA LUAD between 2011 and 2020 were included. A subset of patients had broad-based panel next-generation sequencing performed on their tumors.

Sex differences in mitochondrial free-carnitine levels in subjects at-risk and with Alzheimer's disease in two independent study cohorts.

A major challenge in the development of more effective therapeutic strategies for Alzheimer's disease (AD) is the identification of molecular mechanisms linked to specific pathophysiological features of the disease. Importantly AD has a two-fold higher incidence in women than men and a protracted prodromal phase characterized by amnestic mild-cognitive impairment (aMCI) suggesting that biological processes occurring early can initiate vulnerability to AD. Here, we used a sample of 125 subjects from two independent study cohorts to determine the levels in plasma (the most accessible specimen) of two essential mitochondrial markers acetyl-L-carnitine (LAC) and its derivative free-carnitine motivated by a mechanistic model in rodents in which targeting mitochondrial metabolism of LAC leads to the amelioration of cognitive function and boosts epigenetic mechanisms of gene expression.

Remote Symptom Monitoring in Thoracic Surgery Patients After Discharge.

Objective: Evaluate an electronic platform for remote symptom monitoring to enhance postdischarge care in thoracic surgery using patient reporting of symptoms.

Summary Background Data: Owing to the increased use of enhanced recovery after surgery protocols, patients are spending a larger portion of their postoperative course at home. For patients undergoing complex operations, this represents an opportunity for early identification of abnormal symptoms at home before deterioration.

YAP regulates periosteal expansion in fracture repair.

Bone fracture repair initiates by periosteal expansion. The periosteum is typically quiescent, but upon fracture, periosteal cells proliferate and contribute to bone fracture repair. The expansion of the periosteum is regulated by gene transcription; however, the molecular mechanisms behind periosteal expansion are unclear.
