Background: Aspirin is the most widely used drug in medicine for cardiovascular and as recently for its role in cancer prevention. Although the risk of bleeding events increased following regular use of aspirin, little is known about the association of aspirin and hematuria. The present study aimed to evaluate the association of regular aspirin use and microscopic hematuria in elderly. Metho...

We describe a phenomenological model for the conductance feature near 0.7 × 2e 2 /h that occurs in quantum point contacts. We focus on the transconductance at finite source-drain bias and contrast our model with the results expected from a single-particle picture. Good agreement is seen in comparing the model with experimental data, taken on ultra-low-disorder GaAs induced electron systems. Alt...

Thromboangiitis obliterans (TAO, or Buerger's disease) is a rare inflammatory vasculitis that commonly involves small and medium-sized arteries of the extremities of tobacco smokers between the ages of 25 and 50 years. Although the diagnosis is based on the clinical picture and angiographic findings, we studied the microvascular involvement by nailfold capillaroscopy. We evaluated by nailfold c...

LTHOUGH FLUORESCENCE microscopy had its beginnings over half a century ago, it has only recently gained widespread usage as a research tool, and practical applications have yet to be fully exploited. Blood has been one of the tissues most extensively studied by fluorochroming,’ but few reports have been published in English. In addition, the previously reported saline dilution technics for supr...

This paper deals with a practical solution for finding and integrating information from the Web. Since some of the ideas of our BUSTER system are already known we focus on two issues: we introduce the Comprehensive Source Description (CSD), a necessary description for information sources that allows extra services such as integration or translation and a new feature that allows a combined searc...

The symmetries of the DNA double helix require a new term in its linear response to stress: the coupling between twist and stretch. Recent experiments with torsionally-constrained single molecules give the first direct measurement of this important material parameter. We extract its value from a recent experiment of Strick, et al. and find rough agreement with an independent experimental estima...

The rigorous microscopic theory of equilibrium crystal shapes has made enormous progress during the last decade. We review here the main results which have been obtained, both in two and higher dimensions. In particular, we describe how the phenomenological Wulff and Winterbottom constructions can be derived from the microscopic description provided by the equilibrium statistical mechanics of l...

The morphological-functional study of microcirculation is of fundamental importance; in fact, the microvascular bed is directly involved both in autoimmune etiopathogenesis pathologies, and in acute and chronic inflammatory etiopathogenesis pathologies. Oral capillaroscopy is a very stimulating method for studying microcirculation, because of the possibility of studying small vessels in vivo by...

Capillaroscopy is a noninvasive and harmless morphological method for examination of the nailfold capillaries in both suspected and already diagnosed patients with systemic connective disease. The most useful aspect is in discrimination between the patients with primary and secondary Raynaud's phenomenon. Many of the mentioned features should make capillaroscopy a part of the diagnostic algorit...
