The authors address the value of endoscopic retrograde cholangiopancreatography, ultrasonography, computed tomography, magnetic resonance imaging and endoscopic ultrasound for the diagnosis of cystic and solid neoplasms of the pancreas, demonstrating that each of them is of great importance to undoubtedly increase the diagnostic accuracy of the biliopancreatic system diseases. The best method f...

A tremendous diversity of ligand binding proteins exists in nature. This undoubtedly creates considerable opportunities for scientific and medicinal applications. In this chapter, we will consider a range of ligand binding proteins, with particular attention to two classes, namely the ligand-binding proteins of the bacterial periplasm and odorant-binding proteins, because these proteins are the...

The advances of mobile devices and technology have permitted their inclusion on our daily activities, supporting and propelling productivity and communication on several levels. Moreover, the ever-growing diversity and potential of these devices extends their usage through multiple settings, accentuating their ubiquitous and pervasive nature. One of the major contributions to this is undoubtedl...

The notion of context in context-aware applications is not merely an issue of external situational circumstances or device/channel properties, but it could also refer to a wide array of user characteristics that have an effect throughout users’ interactions with a system. Human factors such as cognitive traits and current state, from a psychological point of view, are undoubtedly significant

botany as anatomy, biochemistry, ecology, genetics, morphology, physiology, and systematics. In the future, plant conservation, with its emphasis on the preservation of rare and endangered species, will undoubtedly also have a significant impact. The most spectacular recent innovations in biotechnology involve improved technology for genetically modifying plants and producing individuals with n...

The satellite has yielded new information on the arrangement of irregularities in sheets and the structure of plasma resonances in the ionosphere. Studies of the geographical distributions of the different kinds of spread F, sporadic E, and other phenomena will be facilitated by the satellite. More phenomena will undoubtedly be recognized as the records are studied.

Investigations on the associative interrelationships between microorganisms have engaged increasing attention in recent years. As is well known, these relationships play an important role in nature and also in many branches of industrial.microbiology. In view of the great significance of these associative phenomena in biology, and especially in microbiological ecology, this is undoubtedly a fie...

an inhibitory action in a hemolytic system. At the time of the above discussion, I.did not know whether such a solution could be prepared. Cases of hemoglobinuria following administration of quinine in malarial individuals do undoubtedly occur. In some cases, the appearance of the hemoglobinuria may be accidental. Leaving these accidental cases and without entering into the discussion of the me...

RELATED LINKS Imagine that a killer is on the loose, one who shoots his victims and flees. Police investigators would undoubtedly respond by visiting each crime scene and meticulously searching for clues. They would photograph the body, take fingerprints and question witnesses. An autopsy would recover the bullet for tests. The authorities could then use this information to establish exactly wh...

To have one’s hunches about how a simple combination of processes will behave repeated dashed by one’s own computer program is a humbling experience that no experimental psychologist should miss. Surprises are likely when the model has properties that are inherently difficult to understand, such as variability, parallelism, and nonlinearity—all, undoubtedly, properties of the brain. Hintzman, 1990
