A generalized dilaton action is considered of which the standard dilaton black hole and spherically reduced gravity are particular cases. The Arnowitt-Deser-Misner (ADM) and the Bondi-Sachs (BS) mass are calculated. Special attention is paid to both the asymptotic conditions for the metric as well as for the reference space-time. For the latter one we suggest a modified expression thereby obtai...

BACKGROUND Acute Hill-Sachs reduction represents a potential alternative method to remplissage for the treatment of an engaging Hill-Sachs lesion. This study biomechanically compared the stabilizing effects of an acute Hill-Sachs reduction technique and remplissage. METHODS Six cadaveric shoulders were tested. For the acute Hill-Sachs lesion, a unique model was used to create a 30% defect, co...

Background:   To assess the outcome of the remplissage arthroscopic surgical method in patients with anterior shoulder dislocation associated with Hill-Sachs lesion.     Methods:   Ten patients with anterior shoulder dislocations and Hill-Sachs lesions were entered into this study and were operated on by the remplissage arthroscopic surgical method. They were followed up 22 months after surgery...

BACKGROUND Globally, about five per cent of children are born with congenital or genetic disorders. The most common autosomal recessive conditions are thalassaemia, sickle cell disease, cystic fibrosis and Tay-Sachs disease, with higher carrier rates in specific patient populations. Identifying and counselling couples at genetic risk of the conditions before pregnancy enables them to make fully...

Tay-Sachs disease (TSD) is a recessively inherited neurodegenerative disorder caused by mutations in the HEXA gene resulting in β-hexosaminidase A (HEX A) deficiency and neuronal accumulation of GM2 ganglioside. We describe the first patient with Tay-Sachs disease in the Cypriot population, a juvenile case which presented with developmental regression at the age of five. The diagnosis was confi...

Malaria, a disease that has afflicted humans for more than 10,000 years (Frederick L. Dunn 2003), today infects some 300 million people and kills 1 million each year (Jeffrey D. Sachs 2001). Despite important advances in the control of malaria during the twentieth century, the disease remains stubbornly prevalent throughout much of the world. Faced with this huge global burden, international or...
