Vascular changes undoubtedly play a significant role in the pathogenesis of psoriasis. The present study concerns the local hemodynamics of psoriatic plaques measured by skin clearance of radioactive substances. This method gives a rough measure of local vascular dynamics (1—7), and, despite any shortcomings, probably supplies a more realistic picture than does use of colorimetry or plethysmogr...

Circular dichroism (CD) spectroscopy is by far the most widely used technique for protein secondary structure analysis. A survey of the scientific literature will reveal that Robert Woody (Fig. 1) has undoubtedly been a pioneer in the elucidation of the relationship between CD and protein structure and

Immunity to rickettsiae is enhanced by both T-lymphocytes and humoral antibodies; however, the principal effector of rickettsial killing is the macrophage. Lymphokines may play an important role. There is undoubtedly a complex in vivo interaction between the immune, phagocytic, and inflammatory host defenses against these obligate intracellular bacteria.

Remember all the to-do a couple of years ago about whether Florence Nightingale was a suitable role model l. for today's nurses? Tell you what, her common sense opinions on matters related to nurses and nursing seem just as apposite now as they undoubtedly were during her lifetime.

In this short review we study the state of the art of the great challenge of contemporary physics which is reconcile Quantum Theory and its best contribution the Standard Model of Particle Physics and General Relativity. The reconciliation passes undoubtedly through the idea of a fractal universe. Mathematics Subject Classification: Primary 83F05. Secondary 83C45

While circadian rhythms in fluid intake, urine production, and urine storage have been substantiated in diurnal human and nocturnal rodents, the mechanism(s) underlying it is largely unknown. With the elucidations of molecular clockwork and its functional significance in mammals, new opportunities arise to investigate possible circadian control of voiding function and dysfunction, which undoubt...

variants. Consequently, phyB may be an attractive candidate for allele-mining and targeted breeding approaches to reduce, or enhance, thermomorphogenic growth responses in crop species in efforts to breed climate warming-resilient cultivars. These and other matters will undoubtedly be addressed in future research endeavours following the milestone discovery of phyB acting [102_TD$DIFF]as a ther...

Sistemi Informativi LS 2 One image is worth 1,000 words… Undoubtedly, images are the most widespread MM data type, second only to text data Thus, it's not surprising that most efforts related to MMDB's have concentrated on images, in particular: Automatic extraction of features Similarity measures Indexing … Thus, let's move to see which are some basic features of images…

Transfusion-related acute lung injury (TRALI) has emerged as one of the leading causes of transfusion-related morbidity and mortality and is undoubtedly under diagnosed. It is a serious pulmonary syndrome that can lead to death if not recognised and treated promptly. The diagnosis of TRALI is based primarily upon clinical signs and symptoms and is, in part, a diagnosis of exclusion.

This surgical technique has permitted re-entry into the intrahepatic and extrahepatic biliary tree for the purpose of dilatation and the manual propulsion of debris through a ductal anastomosis. The method undoubtedly has other applications in the treatment of complicated biliary duct problems.
