Morphology and evolution of caudal fin in lamniform sharks
Sharks have a distinct asymmetrical caudal fin referred to as heterocercal tail that is a key characteristic of the group and has diversified within sharks in ways that are correlated with lifestyle. However, practically no study examining the evolutionary trend and history of the caudal fin …

An Intramural, Tension-modulating Reflex in the Rat Caudal Artery
<p>Electrical field stimulation (EES) of preconstricted arteries causes relaxation. This relaxation is of either neuronal, vascular smooth muscle, and/or endothelial origins. We have shown that EFS-induced relaxation of intact, phenylephrine (PE) preconstricted rat tail artery (RTA) rings was …

Contribuição ao conhecimento da oesteologia Pachypops adspersus (Steindachner): complexos cefálicos e caudal
We have analised here the osteology of the cephalic bones and tail complex of young and adult fishes of the Pachypops adspersus (Steindachner) class, twenty of which were available, having in view the importance of these structural components on taxinomic, philogenetic and evolutive interpretation …

The effect of Zoledronate treatment timing on lumbar and caudal vertebrae in ovariectomized rats
… a potent bisphosphonate, on the lumbar and caudal vertebrae in ovariectomized [OVX], female Wistar rats. Methods: Twenty nine rats were divided into four groups according to their treatment: OVX at week 0 (n=5), OVX+earlyZOL (20 jig/kg s.c. week 0, n=8), OVX+late ZOL (20 jlg/kg s.c. week 8, …

Effect of Kinematics and Caudal Fin Properties on Performance of a Freely-Swimming Fin
… on the oscillatory form of locomotion where the caudal fin pitches to generate necessary thrust as seen in boxfish. We intend to investigate the Caudal fin kinematics and its physical properties on locomotion performance. To better understand, we build an automated robo-physical model that swims …

Differences of vertebral spreading levels of solutions in the epidural space between the lumbar and the caudal injection
"목적: 요하지 통증의 가장 많은 원인이 척추와 연관된 통증이며, 가장 흔한 퇴행성 병변은 하부 요추 및 제 1 천추 부위이고 이들과 연관된 통증 유발 관련 신경근은 제 5 요추 신경근과 제 1 천추 신경근이다. 이러한 요하지통의 치료에 있어 경막외강내로의 국소마취제 단독이나 국소마취제에 스테로이드의 혼합 투여는 흔히 사용 되어지고 있는 중재적 치료법 중의 하나이다. 그러나 이러한 치료법을 시행할 때 사용되는 약물의 적정 용량에 대하여는 거의 연구 되어지지 않았으며, 시술자마다 경험적으로 사용하고 있다. 따라서 하요부 및 제 …
