Curvas de Intensidad-Duración-Frecuencia para el Valle Central de Costa Rica
(1998-10)En el Valle Central de Costa Rica la distribución de la precipitación no es uniforme a lo largo de toda su extensión. Consecuentemente, una descripción adecuada de las intensidades de lluvia dentro del Valle Central no ... -
Curvas ROC y Vecinos Cercanos, Propuesta de un Nuevo Algoritmo de Condensación
(2011-03-18)k-NN criteria are non parametric methods of statistical classificaction. They are accurate, versatile and distribution free. However, their computational cost may be too expensive; especially for large sample sizes. We ... -
Curvatura en teorías generalizadas de Yang-Mills
(2009-01-13)The curvature in R1+3 spaces with a generalized Yang-Mills connection is studied and the results are analyzed. Other options borne by modifications of the base space are also studied and commented. The present situation ... -
Cutaneous leishmaniasis in rural Costa Rica (Short report)
(1989-05)Cutaneous leishmaniasis occurs in people exposed to wet, forested regions of Costa Rica. Although it is a reportable disease, there is no definitive information on prevalence of either present or past infection in rural ... -
Cyclin-dependent kinase 4/6 inhibitors as first-line treatment for post-menopausal metastatic hormone receptor-positive breast cancer patients: a systematic review and meta-analysis of phase III randomized clinical trials.
(2018)Background To compare the efficacy and toxicity of the combination of cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors and nonsteroidal aromatase inhibitors (AI) versus AI alone as first-line therapy for patients with ... -

Cytotoxic effect induced by retinoic acid loaded into galactosyl-sphingosine containing liposomes on human hepatoma cell lines
(2006)Two retinoids, ATRA and 13cisRA, were incorporated into liposomes of different composition and charge and added to two hepatoma cell lines with different degree of transformation to measure cytotoxicity by MTT assay. ... -
Cytotoxicity induced in myotubes by a Lys49 phospholipase A2 homologue from the venom of the snake Bothrops asper: Evidence of rapid plasma membrane damage and a dual role for extracellular calcium
(2007-12)Acute muscle tissue damage, myonecrosis, is a typical consequence of envenomations by snakes of the family Viperidae. Catalytically-inactive Lys49 phospholipase A2 homologues are abundant myotoxic components in viperid ... -
Cytotoxicity of Lachesis muta muta snake (bushmaster) venom and its purified basic phospholipase A2 (LmTX-I) in cultured cells
(2007)Human envenoming by Lachesis muta muta venom, although infrequent, is rather severe, being characterized by pronounced local tissue damage and systemic dysfunctions. Studies on the pharmacological actions of L. m. muta ... -
Cytotoxicity of snake venom Lys49 PLA2-like myotoxin on rat cardiomyocytes ex vivo does not involve a direct action on the contractile apparatus
(2021-09)Viperid snake venoms contain a unique family of cytotoxic proteins, the Lys49 PLA2 homologs, which are devoid of enzymatic activity but disrupt the integrity of cell membranes. They are known to induce skeletal muscle ...
