A simple technique is described for producing high-quality functional images of regional ventilation during physiological tidal breathing of the inert gas 81mKr. These images are quickly obtained on a gamma-camera without the need of computerized systems for data acquisition and display and are directly comparable with those of perfusion obtained with 99mTc-labelled macroaggregates. The short t...

conclusions in comparison with road traffic accidents on city streets, trauma patients in rtas on roads out of the city have longer pre-hospital time intervals and more severe injuries; therefore this group needs more pre-hospital resuscitation interventions. results findings of this study showed that, 75% of rtas occurred on city streets (n = 1 251). motor-car accidents were the most frequent ...

AIM The aim of this study was to assess the role of labelled leukocyte scintigraphy in the diagnosis and monitorization of response to therapy of patients with active bronchiectasis. MATERIAL AND METHODS Twenty patients underwent (99m)Technetium hexamethylpropyleneamine oxime ((99m)Tc-HMPAO) labelled white blood cell (WBC) scintigraphy. A second scintigraphy was performed in 13 patients at 10...

Background: Patients with chronic kidney disease (CKD) who undergo chronic haemodialysis (HD) show altered sympathetic tone, which is related to a higher cardiovascular mortality. The purpose of this study was to investigate the effect of transition from pre-HD to HD on cardiac sympathetic innervation. Methods: Eighteen patients aged 58 ± 18 years (mean ± standard deviation [SD]), 13 males and ...

myocardial ischemia (mi) resulting in infarction is an important cause of mortality and morbidity worldwide. acute ischaemia rapidly impairs myocardial contractile function. myocardial dysfunction persisting for several hours after transient non-lethal ischaemia, eventually resulting in full functional recovery is termed as myocardial stunning. hibernation is now thought to be the consequence o...

Over the last two decades, genetic lineage tracing has allowed for the elucidation of the cellular origins and fates during both embryogenesis and in pathological settings in adults. Recent lineage tracing studies using Apln-CreER tool indicated that a large number of post-natal coronary vessels do not form from pre-existing vessels. Instead, they form de novo after birth, which represents a co...

Branchial ionocytes (ICs) are the functional units for ionic regulation in fish. In adults, they are found on the filamental and lamellar epithelia of the gill where they transport ions such as Na+, Cl- and Ca2+ via a variety of ion channels, pumps and exchangers. The teleost gill is extrinsically innervated by the facial (VI), glossopharyngeal (IX) and vagus (X) nerves. The IX and X nerves are...

The lateral cervical nucleus receives input from the spinocervical tract and projects to the thalamus and mesencephalon. The organization of this nucleus was examined using two immunocytochemical methods. Pre-embedding immunolabelling was performed using an antibody against glutamate decarboxylase, and post-embedding immunogold-reaction was performed with an antibody to glutaraldehyde-fixed GAB...
