Although techniques for the short-term control of end-tidal gases exist, the lack of a satisfactory technique for longer-term control of the end-tidal gases has limited protracted physiological experiments of this nature. We have constructed a chamber in which subjects can be comfortable for many hours while having their end-tidal gas composition monitored(More)
The extracellular matrix surrounding the sea urchin embryo (outer ECM) contains fibers and granules of various sizes which are organized in recognizable patterns as shown by ultrastructural studies, particularly stereoimaging techniques. The use of the ruthenium red method for retaining and staining the ECM, with modifications of the Luft (Anatomical Record(More)
Infanticide has been proposed to be a pathological response to overcrowding or other forms of environmental stress and thus a maladaptive behavior. However, in male house mice this behavior is predictable and is modulated by learning. Committing infanticide can increase a male's reproductive success and in some situations may therefore be an adaptive(More)

Although rare in its idiopathic form, pulmonary arterial hypertension (PAH) is not uncommon in association with various associated medical conditions, most notably connective tissue disease (CTD). In particular, it develops in approximately 10% of patients with systemic sclerosis and so these patients are increasingly screened to enable early detection. The(More)
The British Thoracic Society (BTS) guideline for emergency oxygen use in adult patients was commissioned by the BTS and developed in conjunction with 21 other colleges and societies prior to publication in 2008. One of the specific aims of the Guideline Development Group was to audit the use of oxygen in UK hospitals before the guideline was published and(More)
Our aim is to assess the safety and potential clinical benefit of intravenous iron (Ferinject) infusion in iron deficient patients with idiopathic pulmonary arterial hypertension (IPAH). Iron deficiency in the absence of anemia (1) is common in patients with IPAH; (2) is associated with inappropriately raised levels of hepcidin, the key regulator of iron(More)
read with interest the paper by Bellomo and colleagues [1] in the previous issue of Critical Care. We agree with the authors' fi nal conclusion that there should not be a deliberate policy to decrease the fraction of inspired oxygen (FiO 2) in the absence of accurate and reliable oximetry. In the developed world, accurate and reliable oximetry and blood gas(More)
