4) received vehicle (iso- osmotic sterile aqueous solution of sodium chloride). Postural reaction assessments Postural reaction (wheelbarrowing, hopping, extensor postural thrust, placing, tonic neck reaction and proprioceptive positioning) assessments were done on all dogs every morning during the test period. Electrophysiological recordings All of the dogs were preanesthetized with atropine... Due to the therapeutic potential of gene therapy for neuronal injury, many studies of neurotrophic factors, vectors, and animal models have been performed. The presumed dog β-nerve growth factor (pdβ-NGF) was generated and cloned and its expression was confirmed in CHO cells. The recombinant pdβ-NGF protein reacted with a human β-NGF antibody and showed bioactivity in PC12 cells. The pdβb-NGF was shown to have similar bioactivity to the dog β-NGF. The recombinant pdβ-NGF plasmid was... -

induce peripheral neuropathy [5]. Postural reaction assessments Postural reaction (wheelbarrowing, hopping, extensor postural thrust, placing, tonic neck reaction, and proprio- ceptive positioning) assessments were done on all dogs ev- ery morning during the test period. Electrophysiological recordings All dogs were pre-anesthetized with atropine (0.1mg/kg of body weight, IM). Anesthesia was... in the axons and myelin with vacuolation. The dorsal root ganglia of L4, and sciatic and tibial nerves showed degenerative changes and vacuolation. However, the lateral and ventral funiculi of L4 showed a normal histopathologic pattern. Although this subcutaneous administration method did not cause systemic toxicity and effectively induced sensory neuropathy, this study confirmed the possibility of producing a pyridoxine-induced sensory neuropathy model in dogs with short-term administration. -

The Hong Kong Early Child Development Scale (HKECDS) is a tool for assessing holistic early child development in preschoolers aged from three to six years. The original version of the scale, HKECDS, was updated in 2019 (HKECDS-2) to reflect the contemporary context and local curricular expectations. Children (n = 144) from three kindergartens in Hong Kong completed the HKECDS-2 in individual sessions. Rasch model analysis and expert discussions resulted in a short version of the scale (HKECDS-3)... -

skill themes; locomotor, stability, and mani- pulative skills. The locomotor skills involve projecting the body into space in a horizontal, vertical, or diagonal plane: walking, running, jumping, hopping, gallop- ing, and skipping (Gallahue & Ozmun, 2006). The stability skill is the fundamental aspect of learning to move, because all movement involves an element of stability: dynamic balance... -

between the carbon material and the adsorbed gas molecules in the pores of the CNFs. The adsorbed gas molecules on the CNFs transfer the electrons. This phenomenon is referred to as electron hopping. Due to electron hopping, the electrical resistance of the activated CNFs decreased as the CO molecules were adsorbed onto the surface of the CNFs. Therefore, the electrical resistance of the... Polyacrylonitrile/pitch nanofibers were prepared by electrospinning as a precursor for a gas sensor material. Pitch nanofibers were properly fabricated by incorporating polyacrylonitrile as an electrospinning supplement component. Polyacrylonitrile/pitch nanofibers were activated with steam at various temperatures followed by subsequent carbonization to make carbon nanofibers with a highly conductive graphitic structure. Steam activation was effective in facilitating gas adsorption onto the... -

and this process is promoted by electron hopping between surface sites with Fe in different oxidation states, i.e., +2 and +3, in the crystal lattice. When a potential is applied to the Fe3O4/GCE, the electrons were rapidly transferred between the two different oxidation states of Fe, producing unbound electrons at the surface of electrode/elec- trolyte interface. This eventually produces a... In this study, magnetite (Fe3O4) nanoparticles were electrochemically synthesized in an aqueous electrolyte at a given potential of -1.3 V for 180 s. Scanning electron microscopy revealed that dendrite-like Fe3O4 nanoparticles with a mean size of < 80 nm were electrodeposited on a glassy carbon electrode (GCE). The Fe3O4/GCE was utilized for sensing chloramphenicol (CAP) by cyclic voltammetry and square wave voltammetry. A reduction peak of CAP at the Fe3O4/GCE was observed at 0.62 V, whereas... -

showing an insulator effect. However, the introduction of easily electron polarized molecules, such as CO, reduced the electrical resistance compared with air gas. This appears to cause electron hopping effects in the pores [13]. Therefore, it can be concluded that activated carbons, especially those with a seriously degrad- ed graphite structure, can lose their semiconductor characteris- tics... -

현대 디지털 통신시스템에서 없어서는 안되는 중요한 요소 중의 하나가 오류정정부호화 기법이다. 본 논문에서는 디지털 통신 시스템에서 놀라운 성능으로 인하여 주목을 받고있는 터보코드에 비균일 인터리버의 일종인 호핑방식의 알고리즘을 적용한 인터리버를 터보코드에 적용하여 성능을 비교 분석하였다. 기존의 블록 인터리버는 메모리의 입력과 출력이 행과 열에 대해서 차례대로 이루어지는 반면, 호핑방식을 적용한 인터리버는 행과 열을 건너뛰면서 입출력이 이루어지므로 이중으로 인접 데이터간의 최소거리와 평균거리를...
