A multi-cohort study of longitudinal and cross-sectional Alzheimer's disease biomarkers in cognitively unimpaired older adults.

Introduction: The generalizability of neuroimaging and cognitive biomarkers in their sensitivity to detect preclinical Alzheimer's disease (AD) and power to predict progression in large, multisite cohorts remains unclear.

Method: Longitudinal demographics, T1-weighted magnetic resonance imaging (MRI), and cognitive scores of 3036 cognitively unimpaired (CU) older adults (amyloid beta [Aβ]-negative/positive [A-/A+]: 1270/1558) were included. Cross-sectional and longitudinal cognition and medial temporal lobe (MTL) structural measures were extracted.

Ultra-remote robot-assisted right upper lobectomy between the Shanghai and Kashi Prefectures: a case report.

Background: Robot-assisted thoracic surgery has been shown to have several advantages over conventional surgery. As mobile communication technology and surgical robotic devices in China continue to progress rapidly, the conditions for performing remote surgery have been optimized. Consequently, informatized and remote advanced medical cooperation is becoming a new direction for supporting the medical development of border regions and promoting the equitable distribution of medical resources in China.

Metabolic skinflint or spendthrift? Insights into ground sloth integument and thermophysiology revealed by biophysical modeling and clumped isotope paleothermometry.

Unlabelled: Remains of megatheres have been known since the 18th -century and were among the first megafaunal vertebrates to be studied. While several examples of preserved integument show a thick coverage of fur for smaller ground sloths living in cold climates such as and , comparatively very little is known about megathere skin. Assuming a typical placental mammal metabolism, it was previously hypothesized that megatheres would have had little-to-no fur as they achieved giant body sizes.

Exparel and Outpatient Alveolar Bone Grafting: A Feasibility Study.

Objectives: To examine the feasibility of outpatient alveolar bone grafting (ABG) using Exparel (bupivacaine liposome injectable suspension) for donor site analgesia.

Design: Retrospective, observational study.

Setting: Single institution, 39-month retrospective review.

Anterior-temporal network hyperconnectivity is key to Alzheimer's disease: from ageing to dementia.

Curing Alzheimer's disease remains hampered by an incomplete understanding of its pathophysiology and progression. Exploring dysfunction in medial temporal lobe networks, particularly the anterior-temporal (AT) and posterior-medial (PM) systems, may provide key insights, as these networks exhibit functional connectivity alterations along the entire Alzheimer's continuum, potentially influencing disease propagation. However, the specific changes in each network and their clinical relevance across stages are not yet fully understood.
