erythematosus Systemic lupus erythematosus (SLE) is an autoimmune disease that affl icts mainly women in the reproductive years. It is a multisystem disease aff ecting the joints, skin, kidneys and brain and is characterized by autoantibody production by dysregulated B cells, target organ infi ltration by infl ammatory T cells and aberrant immune cell activation due to abnormal antigen presenti...

Let G be a (real or complex) semisimple Lie group, whose Lie algebra g is endowed with a so called jkj{grading, i.e. a grading of the form g = g ?k g k , such that no simple factor of G is of type A 1. Let P be the subgroup corresponding to the subalgebra p = g 0 g k. The aim of this paper is to clarify the geometrical meaning of Cartan connections corresponding to the pair (G; P) and to study ...

Soil water availability is most essential in the Sahelian agriculture but is hampered by several factors. Surface crusts or crust-like surfaces, which are characteristic of most Sahelian soils, have been shown to decrease water in®ltrability and increase runoff. Their type and structure are in ̄uenced by soil texture, vegetation cover, erosion and deposition effects of wind and water. A soil and...

We consider the process dYt = utdt + dWt; where u is a process not necessarily adapted to FY (the ...ltration generated by the process Y ) and W is a Brownian Motion. We obtain a general representation for the likelihood ratio of the law of the Y process relative to Brownian measure. This representation involves only one basic ...lter (expectation of u conditional on observed process Y ): This ...

Environmental studies are confronted with a challenging task to develop appropriate low cost technologies for treatment of liquid wastes. Conventional methods for removing metals from aqueous solutions include chemical precipitation, chemical oxidation or reduction, ion exchange, fi ltration, electrochemical treatment, reverse osmosis, membrane technologies and evaporation recovery. However, th...

Neurocutaneous melanosis is a rare neurocutaneous syndrome defi ned by the presence of multiple and /or giant congenital cutaneous nevi and melanocytic deposits in the central nervous system with the infi ltration of leptomeninges. The major medical concern with giant congenital cutaneous nevi is high risk of developing cutaneous melanoma, leptomeningeal melanoma, and neurocutaneous melanosis. ...

Primary variable switching appears as a promising numerical technique for variably saturated ̄ows. While the standard pressurebased form of the Richards equation can su€er from poor mass balance accuracy, the mixed form with its improved conservative properties can possess convergence diculties for dry initial conditions. On the other hand, variable switching can overcome most of the stated nu...

Prurigo pigmentosa is a type of inflammatory dermatosis characterized by symmetrical pruritic erythematous papules that normally resolve with reticular pigmentation. In severe cases, edematous infi ltrative plaques may be found, but usually no vesicles or bullae. We presented a 32-year-old Taiwanese female, a case of insulin dependent diabetis mellitus with sudden onset of vesicobullae upon ery...

1 of 2 DESCRIPTION A 74-year-old woman has visited to our hospital with general lassitude and appetite loss in October 2010. The patient had experienced abdominal pain for the past 2 months and had become aware of insidious weight loss of 5 kg in the last few months. The abdomen was fl at and soft, and bowel sounds were slightly hyperactive. There was no history of serious illnesses, operations...

In ̄ammation contributes to brain damage caused by ischaemic stroke. Macrophages, as the prevailing in ̄ammatory cell population in stroke lesions, can be visualized using ultrasmall superparamagnetic iron oxide (USPIO) as a cell-speci®c contrast agent for MRI. In this single-centre open-labelled clinical phase II study we tested the potential of USPIO-enhanced MRI for macrophage imaging in human...
