Skin punch biopsies of six children suffering from infantile or late onset Tay-Sachs disease, juvenile Sandhoff disease, or GM gangliosidosis type I, contained axons which, when viewed with the electron microscope, were distended by large amorphous black deposits. These are nonspecific residual bodies. Their large numbers indicate severe disturbance of the nerve cell and may be part of the dyin...

Majorana’s arbitrary spin theory is considered in a hyperbolic complex representation. The underlying differential equation is embedded into the gauge field theories of Sachs and Carmeli. In particular, the approach of Sachs can serve as a unified theory of general relativity and electroweak interactions. The method is extended to conformal space with the intention to introduce the strong inter...

Partial resurfacing of the humeral head with the Hemicap implant has recently become available. Previously, the use of resurfacing in the glenohumeral joint has been used for the treatment of osteoarthritis, cuff tear arthropathy, rheumatoid arthritis, and avascular necrosis. The technique has provided significant pain relief as well as improved function in all pathologies in the available shor...

In this work it is shown that there are some spatially homogeneous but anisotropic models (Kantowski-Sachs and Bianchi type-III), with a positive cosmological constant, for which the inhomogeneities in the distribution of matter on the surface of the last scattering produce anisotropies (in large angular scales θ ∼ > 10 ◦) that do not differ from the ones produced in Friedmann-Lemâıtre-Robertso...

story. Poor countries are poor, in their view, because the poor do not behave like "us". The battle against poverty thus becomes a battle against corruption, wrong ideas and incompetence, and little more. Of course, the morality tale sometimes fits, as in present-day Zimbabwe, where an ageing tyrant, surrounded by rapacious lieutenants, is destroying his country in a vain and desperate attempt ...

  Background : Glenoid bone damages consisting of anterior rim erosion and bony avulsion are very important in decision making for treatment of recurrent dislocation in shoulder joint. This study was aimed to determine the prevalence of these damages in patients with anterior recurrent shoulder dislocation.   Methods : The study was a cross-sectional study evaluating patients with unstable shou...
