A left-sided gallbladder is a rare biliary anomaly with a prevalence of 0.2%. Its identification is important because of the numerous and potentially hazardous associated biliary and vascular anomalies that may be encountered during surgery.

structural analysis of remotely sensed data provides a method of assessing the structural significance of large-magnitude regional metallogenesis in the kerman porphyry cu belt in the southern part of the central iranian volcanic belt. the role of large-magnitude ring structures in the distribution of hydrothermal alteration zones and porphyry copper deposits in the southern part of the kerman ...

Hemangioma, which is a rife benign proliferative lesion with vascular tissue origin, is the most common vascular anomaly of infancy. Cellular hemangioma is one type of these tumors, known as the vascular channel formation of endothelial cells. This report describes a 34-year old man with an exophytic lesion on the lower lip , firm, dome shape ,smooth surface with mild keratosis who came to us  ...

Vascular malformations are inborn errors of vascular embryogenesis present at birth that should be diagnosed in childhood and, when necessary, treated to prevent later complications. The current trend is to classify these lesions according to flow characteristics and the predominant type of vascular channel affected. Given the complexity, and in many cases, the rarity, of vascular malformations...

We use analytic techniques to study the gravitational force that would be produced by different Kuiper-Belt mass distributions. In particular, we study the 3-dimensional rings (and wedge) whose densities vary as the inverse of the distance, as a constant, as the inverse-squared of the distance, as well as that which varies according to the Boss-Peale model. These analytic calculations yield phy...

Vascular malformations are anomalies always present at birth that, contrary to hemangiomas, never regress and may grow during lifetime. Clinical presentation of vascular malformations is extremely variable and ranges from asymptomatic spots of mere aesthetic concern to lesions with high blood flow or located in critical sites that may be life-threatening. Given the low incidence of these disord...
