Trypanosoma cruzi induces tissue disorganization and destruction of chorionic villi in an ex vivo infection model of human placenta
Congenital Chagas’ disease, endemic in Latin America and also present with lower frequency in other countries, is associated with premature labor, miscarriage, and placentitis. The mechanism of tissue invasion and infection ...
Interstitial thermal therapy in patients with localized prostate cancer: Histologic analysis
Objectives. To examine, by way of histologic examination, the destruction of excised prostate glands treated with thermal ablation. Thermal ablation treatment with permanently implanted temperature selfregulating rods ...
Triclosan inhibits tumor necrosis factor-α-stimulated urokinase production in human gingival fibroblasts
Background and Objectives: Destruction of the supporting periodontal tissues is mediated by the action of several proteolytic enzymes. Urokinase is a serine protease that plays a key role in connective tissue destruction ...
Immunostimulatory activity of low-molecular-weight hyaluronan on dendritic cells stimulated with Aggregatibacter actinomycetemcomitans or Porphyromonas gingivalis
(Springer Verlag, 2018)
Objectives Periodontitis is a chronic inflammatory disease characterized by tooth-supporting tissue destruction, which is elicited by the host’s immune response triggered against periodonto-pathogen bacteria. During ...
Estimación del área foliar del arándano (Vaccinium corymbosum) por medio de un método no destructivoA non destructive method for estimating the leaf area of blueberry (Vaccinium corymbosum)
(Bogotá : Universidad de Ciencias Aplicadas y Ambientales, 2012, 2019)
Comparación de métodos directos e indirectos para la estimación del área foliar en duraznero (Prunus persica) y ciruelo (Prunus salicina)A comparison of direct and indirect methods for estimating leaf area in peach (Prunus persica) and plum (Prunus salicina) cultivars
(Universidad Pedagógica y Tecnológica de Colombia, 2017)
Interleukin-21 expression and its association with proinflammatory cytokines in untreated chronic periodontitis patients
Background: Interleukin-21 (IL-21) controls the differentiation of T-helper Th17 cells and induces the production of IL-17 in this T-cell subtype. The aim of this study is to determine the relative expression of IL-21 ...
Levels of interleukin-1β, -8, and -10 and RANTES in gingnival crevicular fluid and cell populations in adult periodontitis patients and the effect of periodontal treatment
(American Academy of Periodontology, 2000)
Background: Various cytokines have been identified at sites of chronic inflammation such as periodontitis. Cytokines are synthesized in response to bacteria and their products, inducing and maintaining an inflammatory ...
A sampling method for predicting the age of first-order branches Un método de muestreo para predecir la edad de ramas de primer orden
(Universidad Distrital Francisco Jose de Caldas, 2019)
A destructive sampling method to estimate the age of first-order branches is presented. The proposed method can be applied only to living tree species showing annual growth rings. The implementation requires an estimate ...
Effectiveness of systematic spike dithering depends on the precision of cortical synchronization
Spike synchronization is a candidate mechanism of cortical information processing. The widely used method of dithering randomly perturbs the spike times of experimental data to construct a distribution of coincidence counts ...
