Spectral intensities in trivalent lanthanide systems: Applications to the Cs2NaDyCl6 and Cs2NaHoCl6 crystals
(, 2008-08-11)
The main goal of this research work is to rationalize the rich vibronic structure of lanthanide type crystals, such as Cs2NaDyCl6 and Cs2NaHoCl6, in the space group Fm3m(Oh5). These systems are known to be highly relativistic ...
Interspecific recognition in Chilean parabiotic ant species
(CIENCIAS, 2003)
In Chile, Camponotus morosus and Solenopsis gayi sometimes co-inhabit a single nest, seemingly in a parabiotic association. To elucidate the nature of this association we conducted behavioural tests that measured aggression ...
Multiple macrodontic multituberculism
(CIENCIAS, 2003)
Ekman-Westborg and Julin [1974: Oral Surg 38:217-222], described multiple macrodontia and multituberculism affecting the teeth without other anomalies (E-WJ). We describe a Chilean case in a 12-year-old with the typical ...
Reduced sulfation of muc5b is linked to xerostomia in patients with Sjogren syndrome
(CIENCIAS, 2008)
Objectives: MUC5B contains sulfated and sialylated oligosaccharides that sequester water required for moisturising the oral mucosa. Xerostomia, in patients with Sjogren syndrome, is generally associated with reduced ...
Lung oxidative stress as related to exercise and altitude. Lipid peroxidation evidence in exhaled breath condensate: a possible predictor of acute mountain sickness
(CIENCIAS, 2005)
Lung oxidative stress (OS) was explored in resting and in exercising subjects exposed to moderate and high altitude. Exhaled breath condensate (EBC) was collected under field conditions in male high-competition mountain ...
Hypoxia-related lipid peroxidation: Evidences, implications and approaches
(CIENCIAS, 2007)
Hypoxia may be intensified by concurrent oxidative stress. Lack of oxygen in relation to aerobic ATP requirements, as hypoxia has been defined, goes along with an increased generation of reactive oxygen species (ROS). ...
Objetivos moleculares para diseñar nuevos fármacos para el tratamiento de la diabetes tipo 2 y la obesidad
(CIENCIAS, 2008)
Current strategies to treat type 2 diabetes (DMT2) include reducing insulin resistance using glitazones, supplementing with exogenous insulin, increasing endogenous insulin production with sulfonylureas and meglitinides, ...
Gelatinolytic activity in gingival crevicular fluid from teeth with periapical lesions
(CIENCIAS, 2008)
Objective. Many matrix metalloproteinases ( MMPs) have been associated with periodontal tissue destruction during chronic and apical periodontitis. The aim of this study was to determine gelatinolytic activity in gingival ...
Dendroclimatological reconstructions in South America: A review
(CIENCIAS, 2009)
Recent years have seen a consolidation and expansion of tree-ring sample collection across South America. Most collections are concentrated in the temperate forests along the eastern and western slopes of the Southern Andes ...
Matrix metalloproteinase 9 in the saliva of patients with Sjogren's syndrome: comment on the article by Goicovich et al - Reply
(CIENCIAS, 2004)
To The Editor: We would like to thank Drs. Konttinen and Azuma fortheir interesting comments concerning some of the observa-tions in our recently published article. We will focus here on 3specific issues raised, namely the ...
