  • The successful introduction of extracellular gadolinium-based contrast agents for contrastenhanced MR angiography, and their wide acceptance today, raise the question of what part an intravascular contrast agent might play in diagnostic imaging. The answer lies in the capacity of an intravascular agent to give us high-level diagnostic information from first pass arterial imaging and, at the same time, to yield additional diagnostic value by allowing delayed imaging from the same contrast injection.

  • Medicine is, fortunately, constantly evolving. Imaging diagnosis is no exception. Technical improvements guarantee further developments in diagnosis. Computed tomography (CT) and magnetic resonance imaging (MRI) have attained a recognized value in the diagnosis of the heart, which is continuing to increase. For this reason, we have now provided a separate chapter on diagnostic imaging of the heart. We have placed sectional CT images next to MR images of the heart to facilitate classification. We have limited ourselves to scans which are presently recognized as standard.

  • The study of the heart and vessels by Magnetic Resonance Imaging represents a relatively new field of application, especially if one considers the large-scale diagnostic use of the technique in the neurological and muscular fields. The explanation of the delayed application in the cardiovascular field can be sought in the methodological complexity linked to the study of moving anatomical structures.

  • The perfect cardiac catheterization technique, including good diagnostic and therapeutic qualities, without risk and with no recovery time for the patient, does not exist. Obtaining initial access to the arterial circulation is the first and most frequent catheterization difficulty encountered by the interventional cardiologist during the procedure. Often, it is also the only difficult part of the exam for the patient because it may cause a vagal reaction or painful spasm.

  • It is worth emphasising however that we now appear to have a range of compounds that in some patients at least, and for some time, help to control positive psychotic symptoms. While this is very important, this benefit may come with associated adverse consequences in other ways for some patients, such as cardio-metabolic side effects that can have a major impact on physical health. Clinicians therefore will need to exercise careful and skilled judgement about which antipsychotic to use in order to benefit individual patient’s symptoms, and minimise adverse health effects.

  • In utero, the placenta is the main site for gas exchange for the developing foetus and the blood flow to the foetal lung is minimal. Blood from the right ventricle bypasses the lungs and passes directly from the pulmonary artery to the aorta via a foetal vessel called the arterial duct. After birth, a number of changes occur in transition from the foetal to the newborn circulation including expansion of the lungs (which reduces pulmonary vascular resistance) and closure of the arterial duct, so that blood now perfuses the lungs.

  • Several new aspects have been highlighted: for example, a novel role for lipids as receptors which drive protein sorting, the diversity of the sorting events that occur at the level of the Golgi apparatus, and the cross talk between exocytosis and autophagy. Moreover, an interesting example of how the knowledge of these pathways is exploited to generate novel secretory routes to direct the synthesis of bio-molecules in “cell factories” is discussed.

  • Magnetic resonance (MR) imaging has become the leading cross-sectional imaging method in clinical practice. Since the 1980s, continuous improvements in hardware and software have significantly broadened the scope of applications. At present, MR imaging is not only the most important technique in neuroradiology and musculoskeletal radiology, but has also become an invaluable diagnostic tool for abdominal, pelvic, cardiac, breast and vascular imaging.

  • The art of imaging blood vessels in the human body is called angiography. Since its inception, physicians have benefited from the field of angiography imaging. This has helped them to diagnostically treat patients with various kinds of vascular diseases. Recently, because of the technology growth in fields of acquisition techniques, such as magnetic resonance, computer tomography, digital subtraction angiography, and ultrasound, the vascular imaging research community has become very interested. But acquisition is just one side of the coin.

  • On August 21, 2012, the Court of Appeals for the Fifth Circuit overturned the lower court and lifted the preliminary injunction, reasoning that “Texas’s authority to directly regulate the content of its own program necessarily includes the power to limit the identifying marks that program grantees are authorized to use” and therefore, “Texas may deny WHP funds from organizations that promote elective abortions through identifying marks,” such as the Planned Parenthood name and logo.

  • The latest diagnostic and therapeutic modalities in the management of coronary artery dis‐ ease by coronary artery bypass graft surgery and by percutaneous coronary intervention with stenting and in the interventional management of other atherosclerotic vascular disease have led to a reduction in cardiovascular mortality and morbidity. This book entitled Artery Bypass provides an excellent update on these advances which every physician seeing pa‐ tients with atherosclerotic vascular disease should be familiar with.

  • Vascular device–related infection is suspected on the basis of the appearance of the catheter site or the presence of fever or bacteremia without another source in patients with vascular catheters. The diagnosis is confirmed by the recovery of the same species of microorganism from peripheral-blood cultures (preferably two cultures drawn from peripheral veins by separate venipunctures) and from semiquantitative or quantitative cultures of the vascular catheter tip.

  • Two cell lines were created; Flp293A and 293 FLEX, both derived from 293 cells. The former pseudotyped with amphotropic and the latter with GaLV envelopes. Recently, a PG13-based murine producer cell line was also established using this strategy (Loew et al. 2009). A favorable chromosomal site for stable and high retroviral vector production is first identified and tagged.

  • To determine why some teachers are more effective than others, Bosshardt and Watts (1990) investigated teacher effects on student learning in high school economics classes using fixed- and random-effects models. The teacher characteristics they examined included college credits in economics, non-credit workshops in economics, years of teaching experience, and the extent of teachers’ past instruction in economics. They found that the most effective teachers were those who had completed more courses in economics.

  • As a result of adaptation to desert conditions, camels acquire the ability to produce diluted milk. This involves the production of milk with a higher water content when the animal is dehydrated than when it is fully watered. They do this by withdrawing water preferentially from the intestines under the action of prolactin and oxytocin. The ability to dilute milk under similar conditions of water stress has also been demonstrated in women and in cows. Milk dilution is not known in other mammals.

  • Presyncopal symptoms vary in duration and may increase in severity until loss of consciousness occurs, or they may resolve prior to loss of consciousness if the cerebral ischemia is corrected. The differentiation of syncope from seizure is an important, sometimes difficult, diagnostic problem.Syncope may be benign when it occurs as a result of normal cardiovascular reflex effects on heart rate and vascular tone, or serious when due to a life-threatening cardiac arrhythmia.
