Robots perform tasks such as displacement, exploration or object transportation under different environments and operating conditions. In search of a high degree of mobility, versatility and robustness, researchers used the social insect metaphor and the selfassembling and self-reconfiguration abilities displayed when they transport objects or build nests as a model. This led to the design and ...

A 13-year old boy was hit in the right eye by a coin that was thrown at him. He presented to the accident and emergency (A&E) department with an oblique corneal abrasion, microscopic hyphaema, iris-ciliary body dialysis, commotio retinae with retinal haemorrhages and a large retinal dialysis. The limited amount of available data in the medical literature suggests that eye injuries as a result o...

Ectopia cordis is derived from two Latin words which means outside and heart [1]. It is a rare congenital malformation in which the heart is formed outside the thoracic cavity. It occurs in 1 in 5-7 per 1,000,000 live births [2]. It may occur as an isolated defect or in association with other body wall defects that affect the thorax, abdomen or both [3]. It may also be associated with other int...

Amniotic band syndrome is a collection of fetal malformations associated with fibrous bands that appear to entangle or entrap various fetal parts in utero leading to deformation, malformation, or disruption. Ectopia cordis is a rare congenital defect in fusion of the anterior chest wall resulting in extrathoracic location of the heart. In this article, we report a rare case of ectopia cordis an...

Microangiography, using methylene blue injected at eight vitelline vein sites, was performed on 156 developing chick embryos at Hamburger-Hamilton stages 14-22. Two stream patterns were observed. Type A coursed sequentially through the dorsal portion of the sinus venosus, the cranial segments of the primitive atrium and atrioventricular canal, the ventral parts of the primitive ventricle and co...
