Even when the muscles surrounding a joint are inactive, they still exert a damping effect on joint mobility, because of the passive elastic tension exerted by the stretched muscle fibres and their connective tissue (Clemmesen, 1951). For example, if the forearm muscles are allowed to relax and the forearm is then shaken violently, the hand will swing loosely at the wrist; however, if the experi...

Rheumatologists have long considered that joint hypermobility is inherited. The familial aggregation is striking and the pattern of inheritance strongly points to an autosomal dominant mode. The first comprehensive description of symptomatic joint hypermobility in the rheumatological literature is attributed to Kirk, Ansell and Bywaters in 1967 [1]. They coined the term ‘hypermobility syndrome’...

The DNA structure of a fragment containing the SV40 termination sequences was examined using gel mobility assays. The region is shown to contain a DNA bend as evidenced by an abnormal mobility that is progressively accentuated as the temperature is lowered. This represents the strongest example of DNA bending among the collection of SV40 fragments studied. The same fragment was shown previously...

The aim of this paper is the study of some laws of random probability distributions, called hyper Dirichlet processes, charging the product of three sample spaces, with the property that the first and the third components are independent conditional to the second one. The law of the marginals on the first two and on the last two components are specified to be Dirichlet processes with the same m...

Lumbar epidural anesthesia is useful in a variety of chronic benign pain syndromes, including lumbar radiculopathy, low back pain syndrome, spinal stenosis, and vertebral compression fractures. Given the increased number of epidural nerve blocks being performed, some have reported unexplained complications of a transient or permanent nature and with varying degrees of severity. However, no case...

The HDCTs constitute a heterogeneous group of rare genetically determined diseases, the best known of which are Ehlers-Danlos and Marfan syndromes and osteogenesis imperfecta. Hypermobility is a feature common to them all, but it is also a feature that is highly prevalent in the population at large. Symptomatic hypermobile subjects (whose symptoms are attributable to their hypermobility) are sa...

The most common of the primary immunodeficiency diseases are those that involve inadequate antibody production. The characteristic presentation of these disorders is recurrent sinopulmonary infections. An arrest in B cell development at the pre-B cell stage leads to agammaglobulinemia and an insignificant number of B cells. X-linked agammaglobulinemia is the most common of these developmental a...
