Evolving in thin air - Lessons from the llama fetus in the altiplano
(CIENCIAS, 2007)Compared with lowland species, fetal life for mammalian species whose mothers live in high altitude is demanding. For instance, fetal llamas have to cope with the low fetal arterial PO2 of all species, but also the likely ... -
Iron, copper and immunocompetence
(CIENCIAS, 2007)Microminerals including copper and iron are essential to immunity and health in human beings. The development of powerful tools in analytical cell biology and molecular genetics has facilitated efforts to identify specific ... -
Psicología de la salud: Una clave para comprender el fenómeno de la adherencia terapéutica
(CIENCIAS, 2007)The lack of compliance with treatment is a public health problem that affects the patient's quality of life, avoids an objective assessment of therapeutic effectiveness and may even cause death. Non compliance can be ... -
Diseño gráfico en Santiago: habla la ciudad
(HUMANIDADES, 2007)“La ciudad como soporte” fue una frase que escuché hace muchos años, en el taller de diseño gráfico que impartía Waldo González, en la UTEM. Era el tema de un proyecto que tenía por objetivo entender el espacio urbano como ... -
Nosocomial candiduria in women undergoing urinary catheterization: Clonal relationship between strains isolated from vaginal tract and urine
(CIENCIAS, 2007)We determined the incidence of nosocomial candiduria associated with indwelling urinary catheters in 42 women with and without Candida spp. vaginal colonization being treated in the intensive care unit (ICU). We established ... -

MMP-13 and TIMP-1 determinations in progressive chronic periodontitis
(CIENCIAS, 2007)Matrix metalloproteinase (MMP)-13 is a collagenase involved in extracellular matrix degradation either by its direct degradative effects or by processing bioactive substrates. The aim of this study was to determine the ... -
Severe spontaneous cases of bisphosphonate-related osteonecrosis of the jaws
(CIENCIAS, 2007)A new kind of osteonecrosis has been reported, first in connection with chemotherapy and later with bisphosphonate therapy. Bisphosphonates are used as adjunctive therapy with patients suffering from cancer. The connection ... -
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 ... -

(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 ... -
Humic acids as molecular assemblers in the surface-enhanced Raman scattering detection of polycyclic aromatic hydrocarbons
(CIENCIAS, 2008)A humic acid (HA) extracted from lignite was successfully used in surface-enhanced Raman scattering SERS experiments as molecular occlusion assembler deposited onto a Ag colloidal surface to detect the polycyclic aromatic ... -
Vacuum phenomenon in the temporomandibular joint: a clinical, computed tomography and magnetic resonance case report
(CIENCIAS, 2008)A 28-year-old woman presented with a history of clicking and mandibular clenching. She was studied clinically and with axial and coronal CT. The patient was going through a tense emotional period and reported tightening ... -
