Cognitive and gray matter volume predictors of learning across two types of casual video games in older Adults: Action vs Strategy.

Video game based and other computerized cognitive interventions are generally efficacious in bolstering cognition in adults over the age of 60, though specific efficacy varies widely by intervention methodology. Furthermore, there is reason to suspect that the process of learning complex tasks like video games is a major factor underpinning training-related transfer to cognition. The current study examined the neurocognitive predictors of learning of video games, and how those predictors may differentially relate to games of different genres.

An ultra-sensitive surface plasmon resonance biosensor with PtSe and BlueP/WS heterostructure.

This paper presents the design and simulation of a surface plasmon resonance (SPR) biosensor using a Platinum diselenide (PtSe) and Blue Phosphorus/tungsten disulfide (BlueP/WS) heterostructure for biosensing protocols. The simulation is done by using a finite element method (FEM) based COMSOL Multiphysics software. The performance of the SPR biosensor is then optimized for obtaining maximum sensitivity, quality factor, detection accuracy, and low limit of detection (LOD).

Effect of Hypoxia on the Gut Microflora of a Facultative Air-Breathing Loach Lepidocephalichthys guntea.

One of the main risks to fish health in an aquatic environment is hypoxia, which can either lead to respiratory failure or the emergence of various diseases in a fish population. This investigation examined the impact of hypoxia on the gut bacteria of a loach, Lepidocephalichthys guntea, which under the dissolve oxygen stress can gulp air from surface and breathe using its posterior intestine. High-throughput sequencing was used to examine the anterior and posterior parts of the gut of L.

Brain activations elicited during task-switching generalize beyond the task: A partial least squares correlation approach to combine fMRI signals and cognition.

An underlying hypothesis for broad transfer from cognitive training is that the regional brain signals engaged during the training task are related to the transfer tasks. However, it is unclear whether the brain activations elicited from a specific cognitive task can generalize to performance of other tasks, esp. in normal aging where cognitive training holds much promise.

Protocol to establish a disease model in Lepidocephalichthys guntea using Aeromonas hydrophila.

The fish disease model facilitates our understanding of disease dynamics, risk assessment for disease outbreaks, the response of the gut immune system, and the maintenance of ecosystem health. Here, we present a protocol for studying gut immunity modulation by infecting Lepidocephalichthys guntea, a loach fish, with Aeromonas hydrophila. We describe steps for performing intra-peritoneal injection on fish and a bath challenge.
