Primary ciliary dyskinesia (PCD) is a rare, genetically heterogeneous disease characterized by recurrent respiratory tract infections, sinusitis, bronchiectasis and male infertility. The pulmonary phenotype in PCD is caused by the impaired motility of cilia in the respiratory epithelium, due to ultrastructural defects of these organelles. We hypothesized that defects of multi-protein ciliary co...

BACKGROUND In recent years, the focus on patient safety and housestaff supervision has led to a steady increase in institutions providing 24/7 in-hospital (also known as in-house, henceforth referred to as IH) coverage by pediatric intensivists. Effects of this increased attending physician presence on education of pediatric housestaff have not been studied. We hypothesized that IH coverage wou...

The surface active Fe-sites in HZSM-5 with low content of iron (<1000 ppm) activated by steaming and high temperature (up to 1323 K) calcination in inert lead to the formation of surface oxygen (O)ad species from N2O and were characterized quantitatively by transient response method. Only a part of (O)ad deposited on zeolite by decomposing N2O was active in CO oxidation at 523 K. A binuclear Fe...

Squamous cell carcinoma of the head and neck (SCCHN) is an aggressive diseasewith poor patient survival. Galanin receptor 2 (GALR2) is a G protein–coupled receptor that induces aggressive tumor growth in SCCHN. The objective of this studywas to investigate themechanismbywhichGALR2promotes angiogenesis, a critical oncogenic phenotype required for tumor growth. The impact of GALR2 expression on s...

Bark beetles (Coleoptera: Scolytinae) are known to be associated with fungi, especially species of Ophiostoma sensu lato and Ceratocystis. However, very little is known about these fungi in Spain. In this study, we examined the fungi associated with 13 bark beetle species and one weevil (Coleoptera: Entiminae) infesting Pinus radiata in the Basque Country of northern Spain. This study included ...

There were 1323 deaths due to ischaemic heart disease in Belfast from 20 July 1981 to 19 July 1982. Some 496 (37%) of these were in persons aged less than 70 years. By World Health Organisation criteria 247 (19%) of these deaths were classified as definite myocardial infarction and 749 (57%) as possible myocardial infarction. Dyspnoea, collapse, and typical pain were the main symptoms at the on...

We demonstrate an optically controlled waveplate at ~1323 nm using the 5S(1/2)-5P(1/2)-6S(1/2) ladder transition in a Rb vapor cell. The lower leg of the transitions represents the control beam, while the upper leg represents the signal beam. We show that we can place the signal beam in any arbitrary polarization state with a suitable choice of polarization of the control beam. Specifically, we...

For the past 30 years, data have suggested that unique islet populations exist, based on morphology and glucose sensitivity. Yet little has been done to determine the mechanism of these functional differences. The purpose of this study was to determine whether human islets were comprised functionally unique populations, and to elucidate a possible mechanism. Islets or pancreatic sections from 2...

Over the past few years, we have reported on the performance issues faced by TCP/IP based applications on satellite links. Performance is limited by the delay inherent in geosynchronous systems and the probability of bit errors found in any wireless system, including satellite systems. These limitations are becoming more important as new satellite systems o er much higher data transmission rate...
