The postsynaptic density (PSD) is crucial for synaptic functions, but the molecular architecture retaining its structure and components remains elusive. Homer and Shank are among the most abundant scaffolding proteins in the PSD, working synergistically for maturation of dendritic spines. Here, we demonstrate that Homer and Shank, together, form a mesh-like matrix structure. Crystallographic an...

Measurement of various zones on the concave half of etiolated Phaseolus vulgaris L. (cv. Black Valentine) hypocotyls has shown that growth at the basal portion of the elbow and the contiguous upper portion of the shank was stimulated earliest by red light. Growth of these two zones was unaffected by the tissue of the convex half but was inhibited by tissue distal to them. The inhibition was all...

This study determined the effects of two wearable resistance (WR) placements (i.e. thigh and shank) on horizontal force-velocity impulse measures during sprint running acceleration. Eleven male athletes performed 50 m sprints either unloaded or with WR 2% body mass attached to shank. In-ground force platforms were used measure ground reaction forces determine dependent variables interest. The m...

This study was conducted to investigate the effects of mixed bone and brisket meat on the quality characteristics and nutritional components of shank bone extract and rib extract from Hanwoo. The pH values were influenced by the raw bones, mixed bone, brisket meat and their interactions (p<0.05). The salinity, sugar content, turbidity, and essential amino acid values increased significantly wit...

Shank color of domestic chickens varies from black to blue, green, yellow, or white, which is controlled by the combination of melanin and xanthophylls in dermis and epidermis. Dermal shank pigmentation of chickens is determined by sex-linked inhibitor of dermal melanin (Id), which is located on the distal end of the long arm of Z chromosome, through controlling dermal melanin pigmentation. Alt...

The degree of asymmetry in bilateral morphological characters may reflect genetic and environmental stressors. Shank length and diameter, weight and length of the first primary wing feather, and distance between the junction of upper and lower mandibles and auditory canal (face length) were used to classify bilateral types and measure relative asymmetry (RA) in six genetic stocks. The stocks we...

This study investigated intralimb coordination during walking in young and elderly women using the theoretical model of dynamical systems. 20 women, 10 Young (M age=24.6 yr., SD= 3.2 yr.) and 10 Elderly (M age=73.7 yr., SD=4.9 yr.), were videotaped during free speed gait and gait perturbed by an ankle weight. Two parameters, one describing the phasing relationship between segments (mean absolut...

The Schottky electron emitter is the most frequently used electron source in electron microscopes. A suppressor electrode around the emitter is usually employed to prevent emission from the shank of the cathode. A concept of operating the Schottky emitter without the suppressor electrode is proposed with the aim of lowering the potential of the extractor electrode. Simulation results show that ...
