Metacognitive awareness has been shown to be a critical skill for academic success. However, students often struggle to regulate this ability during learning tasks. The current study investigates how features designed to promote metacognitive awareness can be built into the game-based intelligent tutoring system (ITS) iSTART-2. College students (n=28) interacted with iSTART-2 for one hour, comp...

BACKGROUNDS/AIMS The oxidative activity of ceruloplasmin (CP) in serum has been found to be lowered in patients with Alzheimer's disease (AD). We investigated whether changes in CP were reflected by altered iron parameters in AD patients. METHODS Iron parameters, and CP concentration, activity and specific activity were determined in the serum of 41 AD patients and controls. RESULTS CP acti...

The Business Process Model represented as a diagram in Business Process Modeling Notation (BPMN) is a commonly used way how to describe business processes of an organization. Problems connected with a complexity of notation and missing support in tools for the software development can be solved by a transformation to a Unified Modeling Language activity diagram. Another reason for creating such...

Introduction: Alzheimer disease (AD) is a neurodegenerative disorder characterized by the progressive loss of memory and other cognitive functions. Protein kinase Cε (PKCε) is an isoform that most effectively suppresses amyloid beta (Aβ) production and synaptic loss. Methods: In this study, spatial learning and memory for treated rats were evaluated by the Morris water maze test. The activity ...

BACKGROUND Glycogen synthase kinase-3β (GSK3β), cAMP-response element-binding protein (CREB) and brain-derived neurotrophic factor (BDNF) play critical roles in neuronal survival, synaptic plasticity and memory and participate in the pathophysiology of both depressive disorder and Alzheimer's disease (AD). METHODS This study was designed to determine the association of GSK3β activity, CREB ac...

Monoamine oxidases (MAOs) play an important role in Alzheimer's disease (AD) pathology. We report in vivo comonitoring of MAO activity and amyloid-β (Aβ) plaques dependent on the aging of live mice with AD, using a two-photon fluorescence probe. The probe under the catalytic action of MAO produces a dipolar fluorophore that senses Aβ plaques, a general AD biomarker, enabling us to comonitor the...

This vignette demonstrates an analysis of the relative stabilities of 24 carboxylases from model organisms that grow optimally at different temperatures. In the chemical thermodynamic model, changes in both temperature and oxidation potential influence the relative stabilities of the proteins with an overall progression that fits with the growth temperatures of the organisms. The calculations s...

Introduction: Amnesia or loss of memory is the cardinal hallmark of Alzheimer’s disease (AD), a progressive neurodegenerative disorder associated with ageing process. Although, AD had been discovered over a century ago, drugs which could cure or halt the progression of the disease are yet to see the light of the day. However, there has been a growing interest in the use of phytomedicines with m...

Background: Our previous findings indicated that carvacrol and thymol alleviate cognitive impairments caused by Aβ in rodent models of Alzheimer's disease (AD). In this study, the neuroprotective effects of carvacrol and thymol against Aβ25-35-induced cytotoxicity were evaluated, and the potential mechanisms were determined. Methods: PC12 cells were pretreated with Aβ25-35 for 2 h, followed by ...

Background: Since cannabis has been legally allowed for medicinal purposes in many countries, it has become more interesting issue, particularly in neurologic disorders such as Alzheimer’s disease (AD). Inhibition of acetylcholinesterase (AChE) is one of the mechanisms for the treatment of AD. Objectives: The present study aimed to establish a method for preparation of cannabinoids-rich extrac...
