Hawaiian dominant tree species Metrosideros polymorpha varieties glaberrima and polymorpha have glabrous and pubescent leaves, respectively. Sympatric populations at 2040 m elevation showed major differentiation beyond the pubescence itself. The varieties differed substantially in stomatal traits and in leaf composition, leaf water status, and instantaneous gas exchange rates, despite similarit...

The articulation of the four French nasal vowels and their oral counterparts has been investigated for four speakers, using magnetic resonance images of the three-dimensional oral and nasal tracts and the cross-sectional velar opening areas. The analysis suggests that the subjects’ anatomy in the oral and nasal tracts influences the articulation, with intersubject differences in both the vocal ...

A case is reported in which a congenital aneurysm of the right coronary sinus of Valsalva ruptured and dissected into the interventricular septum. M-mode and cross-sectional echocardiographic examination allowed accurate preoperative assessment of the pathologic anatomy, which was confirmed by angiography, surgery and autopsy. Dissection of the interventricular septum by a congenital sinus of V...

With a sound understanding of anatomy, detecting and diagnosing most congenital heart malformations with echocardiography need not be an onerous task. Using all the modalities of ultrasound, the examination should define as completely as possible the morphological and physiological aspects of the malformation. The cross sectional imaging modality is a superb tool for displaying the morphology o...

Cheilolejeunea subgenus Xenolejeunea Kachroo & Schust. is emended to account for variability observed in stem anatomy and lobule structure. Cheilolejeunea subgenus Tegulilejeunea Schust. is reduced to synonymy with subgenus Xenolejeunea. A new sectional classification of subgenus Xenolejeunea is proposed (sections Gigantae, Meyenianae, and Xenolejeunea). A key distinguishes among the sections a...

Background Total Anomalous Pulmonary Venous Connection (TAPVC) is a rare form of congenital heart disease (CHD) in which all pulmonary veins connect to the systemic veins, right atrium or the coronary sinus. Echocardiography is a good screening modality in picking up majority of these cases. Cross sectional imaging is often utilized to establish the anatomy and confirm the diagnoses. In this st...

We report a case of an anomalous origin of a right coronary artery from the left coronary sinus with an inter-arterial course, between the aorta and the main pulmonary artery. This variant has been called malignant because of its association with sudden death, especially in young asymptomatic athletes. Although these variants are rare, knowledge of cross sectional anatomy of the coronary arteri...
