Pathological consequences of stress-induced activation of the hypothalamic-pituitary-adrenal (HPA) axis may be related to the duration rather than to the intensity of HPA axis activation after exposure to the stressor. Consequently a fine analysis of post-stress events is of importance. The present experiments were designed to study the importance of three(More)
Antler is a good model to study bone biology both because it is accessible and because it grows and is shed every year. Previous studies have shown that chemical composition changes as the antler is grown, implying constraints in mineral availability and the physiological effort made to grow it. This study aimed at examining antler mechanical properties to(More)
Researchers have devoted little attention to the possibility that the chemical composition of bone might be variable under normal nutrition conditions. This study assessed antler bone composition of 25 one-year old deer (spikes). Antler content of ash, Ca, P, K, Na, Mg, Fe and Zn was assessed in base and tine, and the mean composition or the difference in(More)
One of the most essential systems applied to the eradication of bovine tuberculosis by Mycobacterium bovis is the epidemiologic surveillance of animals slaughtered in abattoir by means of inspection and sample taking of lesions compatible with tuberculosis, confirming the existence of the disease through culture and molecular detection, which takes weeks(More)
Nuclear factor (NF)-kappaB plays an important role in inflammatory diseases such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). A functional insertion/deletion polymorphism (-94ins/delATTG) has been identified in the promoter of the NFKB1 gene. In addition, a polymorphic dinucleotide repeat (CA) has been identified in proximity to the(More)
In a previous study, antler bone chemical composition was found to differ between base and tip. If such variation is in part due to the physiological effort made to grow the antler, composition trends should differ between antlers from deer population differing in mineral or food availability, or body reserves. To assess this, we examined cortical thickness(More)
Attention has focused on particular neurons as the source of nitric oxide (NO) within the parenchyma of the CNS. In contrast, glial cells have been viewed mainly as potential reservoirs of L-arginine, the substrate for nitric oxide synthase (NOS), and as likely targets for neuronally derived NO because of their proximity and their expression of soluble(More)
The presence of certain vitamin D receptor (VDR) genotypes has been associated with low bone mineral density (BMD) in elderly populations as well as with accelerated bone loss in patients with rheumatoid arthritis (RA). In the present study, VDR genotypes from 120 Spanish patients with RA were investigated. Three VDR gene polymorphisms (BsmI, ApaI and TaqI)(More)
OBJECTIVE To describe the clinical phenotype of an autosomal-dominant pedigree with myotilinopathy. METHODS Two symptomatic patients and six asymptomatic gene mutation carriers were examined. We performed serum chemistry, electrophysiological assessments, magnetic resonance imaging (MRI) of lower limb musculature, histochemical and immunohistochemical(More)
Rats were subjected to the standard four-vessel occlusion model of cerebral transient ischaemia (vertebral and carotid arteries) for 15 and 30 min. After a 30 min recirculation period, protein synthesis rate, initiation factor 2 (eIF-2) and guanine nucleotide exchange factor (GEF) activities, and the level of phosphorylation of the alpha subunit of eIF-2(More)
