Learning and Memory Deficits in Notch Mutant Mice
Notch is a critical component of evolutionarily conserved signaling mechanisms that regulate development and may contribute to plasticity-related processes, including changes in neurite structure and maintenance of neural stem cells. Deficits in the Notch pathway are responsible for Alagille and Cadasil syndromes, which are associated with mental retardation and dementia. Additionally, in postm...
متن کاملAuraptene consolidates memory, reverses scopolamine-disrupted memory in passive avoidance task, and ameliorates retention deficits in mice
Objective(s): Auraptene (7-geranyloxycoumarin) (AUR), from Citrus species has shown anti-inflammatory, neuroprotective, and acetylcholinesterase (AChE) and beta-secretase inhibitory effects. Scopolamine is a nonselective muscarinic receptor antagonist which causes short-term memory impairments and is used for inducing animal model of Alzheimer’s disease (AD). This research aimed to investigate ...
متن کاملthe effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولChanges in vascular reactivity of the coronary artery and thoracic aorta in the delta sarcoglycan null mutant mice
Introduction: Mutations in the delta sarcoglycan gene (d-SG) cause limb-girdle muscular dystrophy type 2F with structural and functional alterations in cardiac, smooth and skeletal muscle. The objective of the present study was to improve information about changes in vascular reactivity of the thoracic aorta and the coronary artery in the perfused heart of the d-SG-null mutant mouse model. ...
متن کاملCompensation for PKMζ in long-term potentiation and spatial long-term memory in mutant mice.
PKMζ is a persistently active PKC isoform proposed to maintain late-LTP and long-term memory. But late-LTP and memory are maintained without PKMζ in PKMζ-null mice. Two hypotheses can account for these findings. First, PKMζ is unimportant for LTP or memory. Second, PKMζ is essential for late-LTP and long-term memory in wild-type mice, and PKMζ-null mice recruit compensatory mechanisms. We find ...
