Connections between the hippocampus (HC) and medial prefrontal cortex (mPFC) are critical for working memory; however, the precise contribution of this pathway is a matter of debate. One suggestion is that it may stabilize retrospective memories of recently encountered task-relevant information. Alternatively, it may be involved in encoding prospective memories, or the internal representation of future goals. To explore these possibilities, simultaneous extracellular recordings were made from mPFC and HC of rats performing the delayed spatial win-shift on a radial maze...

Minimum space allowances for laboratory rats are legislated based on weight and stocking rates, with the understanding that increased housing density encourages crowding stress. However, there is little evidence for these recommendations, especially when considering positive welfare outcomes. This study consisted of two experiments which investigated the effects of housing density (rats per cage), space allocation (surface area per rat) and social rank (dominance hierarchy) on the ability to perform simple behavioural tests...

BACKGROUND: Ventral incisional hernia (VIH) is not uncommon following liver transplantation. Open repair was traditionally adopted for its management. Laparoscopic repair of VIH has been performed successfully in nontransplant patients with evidence of reduced recurrence rates and hospital stay. However, the application of VIH in post-transplantation patients has not been well established. Herein, we provide our initial experience with laparoscopic repair of post-transplantation VIH. METHODS: From March 2015 to March 2016, 18 cases of post-transplantation VIH were subjected to laparoscopic repair (laparoscopy group)...

BACKGROUND: We previously introduced a novel noninvasive technique of intracranial pressure (ICP) monitoring in children with open fontanelles. OBJECTIVE: To compare the ICP obtained by our new technique to the ICP derived from an intradurally implanted ICP measurement device (external ventricular drain, subdural ICP device). METHODS: Children with open fontanelles and need of intracranial monitoring were included in this study. A standard ICP probe was placed upon the frontal fontanelle and data were compared with the values recorded by an already invasively implanted subdural ICP technique...

Functional infrared thermal imaging (fITI) is considered a promising method to measure emotional autonomic responses through facial cutaneous thermal variations. However, the facial thermal response to emotions still needs to be investigated within the framework of the dimensional approach to emotions. The main aim of this study was to assess how the facial thermal variations index the emotional arousal and valence dimensions of visual stimuli. Twenty-four participants were presented with three groups of standardized emotional pictures (unpleasant, neutral and pleasant) from the International Affective Picture System...

Secondary use of medical and administrative databases has become a powerful tool for epidemiological studies. In that respect, the recent access opening of French nationwide health record database or SNDS (Système National des Données de Santé) is a great opportunity to carry out comprehensive health studies at the country level. However, using this database is far from being straightforward for non-expert data scientists; so, dedicated tools needed to be developed. Our contribution is focused on data management and visualization tools able to query and cope with the complexity of care pathways of patients...

Oak savanna, a transitional ecosystem between open prairie and dense oak forest, was once widespread in Minnesota. Upon European settlement much of the oak savanna was destroyed. Recently, efforts to restore this ecosystem have increased and often include the reintroduction of fire. Though fire is known to serve an important role within oak savannas, there are currently few studies which address fire regimes on timescales longer than the last century. This research presents a paleoecological history of Sherburne National Wildlife Refuge (SNWR) in MN, USA, spanning the last ~8000 years...

Longjing Medial College, established in Longjing, Yanbian, China on September 12, 1945, existed for about 1 year and 6 months until it was renamed as the Medical Department of Dongbei Junzheng Daxue Jilin Fenxiao in April 1947. However, there are only few records and studies on Longjing Medical College in Yanbian as well as in Korea. In order to fill the gap, this study attempted to restore the history of Longjing Medical College built in Yanbian, China immediately after the liberation. In particular, it analyzed how and why the Longjing Medical College was founded and operated, and which relations the college had with the post-war medical educational institutions, focusing on the 'disconnection' and 'continuity' in the historical sense...
