Convolutional neural networks uncover the dynamics of human visual memory representations over time.

The ability to accurately retrieve visual details of past events is a fundamental cognitive function relevant for daily life. While a visual stimulus contains an abundance of information, only some of it is later encoded into long-term memory representations. However, an ongoing challenge has been to isolate memory representations that integrate various visual features and uncover their dynamics over time.

Single genomic enhancers drive experience-dependent GABAergic plasticity to maintain sensory processing in the adult cortex.

Experience-dependent plasticity of synapses modulates information processing in neural circuits and is essential for cognitive functions. The genome, via non-coding enhancers, was proposed to control information processing and circuit plasticity by regulating experience-induced transcription of genes that modulate specific sets of synapses. To test this idea, we analyze here the cellular and circuit functions of the genomic mechanisms that control the experience-induced transcription of Igf1 (insulin-like growth factor 1) in vasoactive intestinal peptide (VIP) interneurons (INs) in the visual cortex of adult mice.

Thiamine Administration and the Prevalence of Delirium in the Intensive Care Unit: A Retrospective Before and After Interventional Study.

Background: Thiamine is an essential co-factor for aerobic intracellular respiration, nerve conduction, and muscle contraction. Thiamine deficiency is common in the intensive care unit (ICU). Delirium is a frequent unwanted symptom among critical ill patients.

Low molecular weight heparin for venous thromboembolism prophylaxis in general Intensive Care Unit patients: an anti-factor Xa level-based approach.

Background: Venous thromboembolism (VTE) in the Intensive Care Unit (ICU) is associated with significant morbidity and mortality therefore prevention is imperative to reduce its burden. VTE prophylaxis in ICU patients is primarily pharmacological using low molecular weight heparin (LMWH). Plasma anti-factor Xa (anti-FXa) levels may be used to measure LMWH activity.
