Learning-related plasticity at excitatory synapses in the mammalian brain requires the trafficking of AMPA receptors and the growth of dendritic spines. However, the mechanisms that couple plasticity stimuli to the trafficking of postsynaptic cargo are poorly understood. Here we demonstrate that myosin Vb (MyoVb), a Ca2+-sensitive motor, conducts spine trafficking during long-term potentiation ...
As humans contain a currently active L1 (LINE-1) non-LTR retrotransposon family (Ta-1), the human genome database likely provides only a partial picture of Ta-1-generated diversity. We used a non-biased method to clone Ta-1 retrotransposon-containing loci from representatives of four ethnic populations. We obtained 277 distinct Ta-1 loci and identified an additional 67 loci in the human genome ...
A scheme for the estimation of compressional wave speed and attenuation has been developed using broadband explosive sources. Sediment compressional speeds were estimated using hybrid methods based on the modal dispersion behavior of broadband acoustic propagation. In this hybrid scheme, we have used Genetic Algorithm (GA) as the main search tool. Local optimization tools were used to finetune ...
Recent investigations have shed much light on the nuclear and electronic factors that control the rates of long-range electron tunneling through molecules in aqueous and organic glasses as well as through bonds in donor-bridge-acceptor complexes. Couplings through covalent and hydrogen bonds are much stronger than those across van der Waals gaps, and these differences in coupling between bonded...
ABSTRACT: Aims and background: Osteogenesis imperfecta is an authosomal dominant disease that almost always involve the connective tissues .The major problem in these patients is inability to synthesize collagen type -1, that leads to multiple long bone fractures. This case report is going to describe management of anesthesia in a patient with Osteogenesis imperfecta, who was scheduled fo...
Objectives: Dry Needling (DN) is a novel and effective intervention for patients with Myofascial Pain Syndrome (MPS). Some characteristics, such as needle penetration depth, needle insertion into the target muscle, and trigger points must be identified in this intervention. The Ultrasound (US)-guided DN is a technique that involves needle insertion at the site of injury and the simulation of ti...
A synchronous-amplitude-controlled and time-delay-controlled photonic controller for phased-array antenna applications is proposed and demonstrated. Amplitude control is based on a variable optical attenuator system that operates in synchronism with the photonic delay line (PDL). This amplitude control system can provide both the signal calibration for the different PDL channels and settings re...
