Projections from thalamic nucleus reuniens to hippocampal CA1 area participate in context fear extinction by affecting extinction-induced molecular remodeling of excitatory synapses.

The ability to extinguish contextual fear in a changing environment is crucial for animal survival. Recent data support the role of the thalamic nucleus reuniens (RE) and its projections to the dorsal hippocampal CA1 area (RE→dCA1) in this process. However, it remains poorly understood how RE impacts dCA1 neurons during contextual fear extinction (CFE).

Optical spring tracking for enhancing quantum-limited interferometers.

Modern interferometers such as LIGO have achieved sensitivities limited by quantum noise, comprising radiation pressure and shot noise. To mitigate this noise, a static system is employed that minimizes the quantum noise within the measurement band. However, since gravitational wave inspiral signals are a single frequency changing over time, only noise at the chirp frequency needs to be minimized.

A Nutritional Strategy Based on Multiple Components for Glycemic Control in Type 2 Diabetes: A Multicenter Randomized Controlled Clinical Trial.

Background/objectives: The optimal dietary approach for managing glycemic and metabolic control in type 2 diabetes (T2D) is still uncertain, though it should be tailored for clinical settings. Therefore, we sought to assess the impact of a multicomponent nutritional strategy on glycemic control in T2D patients within a public health system.

Methods: NUGLIC was an open-label, parallel-group, superiority, multicenter randomized controlled trial.

Aldehyde dehydrogenase-2 deficiency aggravates neuroinflammation, nociception, and motor impairment in a mouse model of multiple sclerosis.

Aldehyde dehydrogenase-2 deficiency (ALDH2∗2) found in 36 % of Han Chinese, affects approximately 8 % of the world population. ALDH2 is a mitochondrial key enzyme in detoxifying reactive aldehydes to less reactive forms. Studies demonstrate a potential link between ALDH2∗2 mutation and neurodegenerative diseases.

Consensus-Building Processes for Implementing Perioperative Care Pathways in Common Elective Surgeries: A Systematic Review.

Aims: To identify and understand the different approaches to local consensus discussions that have been used to implement perioperative pathways for common elective surgeries.

Design: Systematic review.

Data Sources: Five databases (MEDLINE, CINAHL, EMBASE, Web of Science and the Cochrane Library) were searched electronically for literature published between 1 January 2000 and 6 April 2023.
