Cerastium candidissimum Correns is an endangered species. Nevertheless, its ornamental characteristics make it ideal candidate for commercial use as a new and landscape plant. As there are no references to the in vitro propagation of this species, present research aims comparatively investigate potential that may have three different populations plant, from Mounts Parnassos (PS), Parnitha (PR),...
High-altitude pulmonary hypertension: a pathophysiological entity to different diseases. M. Maggiorini, F. Léon-Velarde. #ERS Journals Ltd 2003. ABSTRACT: Pulmonary hypertension is a hallmark of high-altitude pulmonary oedema (HAPE) and of congestive right heart failure in subacute mountain sickness (SMS) and chronic mountain sickness (CMS) in the Himalayas and in the end-stage of CMS (Monge9s ...
The effects of sustained anoxia on cardiac electrical excitability were examined in the anoxia-tolerant crucian carp (Carassius carassius). The electrocardiogram (ECG) and expression of excitation-contraction coupling genes were studied in fish acclimatised to normoxia in summer (+18°C) or winter (+2°C), and in winter fish after 1, 3 and 6 weeks of anoxia. Anoxia induced a sustained bradycardia...
Many individual variables have been studied to understand climate change, yet an overall weather situation involves the consideration of many meteorological variables simultaneously at various times diurnally, seasonally, and yearly. The current study identifies a full weather situation as an air mass type using synoptic scale classification, in 30 population centres throughout Canada. Investig...
BACKGROUND The von Hippel-Lindau tumour suppressor protein-hypoxia-inducible factor (VHL-HIF) pathway has attracted widespread medical interest as a transcriptional system controlling cellular responses to hypoxia, yet insights into its role in systemic human physiology remain limited. Chuvash polycythaemia has recently been defined as a new form of VHL-associated disease, distinct from the cla...
Cheyne-Stokes respiration (CSR) is common in patients with congestive heart failure (CHF). This characteristic crescendo-decrescendo pattern of breathing is often seen during sleep in patients with CHF and is a form of central sleep apnoea. Disordered nocturnal breathing leads to oxygen desaturation, poor sleep quality, and altered sleep architecture. These features may lead to complaints of da...
