Effect of 18:3 n-3 geometrical isomers of heated linseed oll on the biosynthesis of arachidonic acid in rat
1990
Abstract The influence of dietary heated linseed oil on the fatty acid composition of rat liver, platelet and plasma phospholipids (PL) with particular reference to the metabolism of linoleic acid (18:2 n-6) were studied. Δ6 and Δ5 desaturase activities and fatty acid composition of hepatic microsomal total lipids (TL) also were determined. Two groups of male weanling rats were fed, for 6 weeks, diets containing 10% (in weight) of a fresh linseed oil (LO group) and of a heated linseed oil (HLO group). The contents of geometrical isomers of linolenic acid (18:3 n-3) were high in the oil heated at 240°C for 10 hours. The pattern of arachidonic acid (20:4 n-6) in the different lipid fractions …

Tarsius tumpara: A New Tarsier Species from Siau Island, North Sulawesi
2008
Abstract: A new, critically endangered species of tarsier, one of the world's 25 most endangered primates, is described from the remote island of Siau, North Sulawesi, based on distinguishing characteristics of the tail tuft, pelage coloration, skull, and vocalizations. Siau is part of the Sangihe Island chain, a volcanic arc composed of islands that rise from the ocean floor. There is a single previous record of a tarsier from Siau; a skull in the Dresden Museum that Meyer (1897) classified with tarsiers from Sangihe Island as Tarsius sangirensis. Sangihe and Siau Islands are geologically separated by about 60 km of ocean that greatly exceeds 1,000 m in depth. Genetic data for the new spec…
Angiopoietin-2 plasma dosage predicts time to first treatment and overall survival in chronic lymphocytic leukemia.
2010
Abstract The clinical relevance of angiopoietin-2 (Ang2) in chronic lymphocytic leukemia (CLL) was previously suggested by the association between high Ang2, and shorter progression-free survival reported in small series of patients. Here, we evaluated Ang2 glycoprotein levels in plasma samples collected from a multicentric cohort of CLL patients (n = 316) using an enzyme-linked immunosorbent assay method, and we investigated its prognostic role in relation to time to first treatment (TTFT) and overall survival. Based on a cutoff equal to 2459 pg/mL, we divided our cohort in 2 subsets (high and low Ang2) composing 100 (31.6%) and 216 (68.4%) patients, respectively. High Ang2 was predictive …
Enfermedad injerto contra huésped en el trasplante de sangre de cordón umbilical de donante no emparentado en adultos con enfermedades hematológicas …
2019
Comparado con la sangre periférica y la médula ósea como fuentes de progenitores hematopoyéticos de donante no emparentado, la sangre de cordón umbilical desencadena una menor alorreactividad contra el receptor, lo que permite el uso de donantes con una mayor disparidad del sistema HLA. Un menor número de linfocitos T en la unidades de cordón umbilical (UCU), pero con un mayor porcentaje de linfocitos T naive, explica en parte la menor incidencia de enfermedad injerto contra huésped (EICH) en el trasplante de sangre de cordón umbilical (TSCU) en comparación con otras fuentes. Sin embargo, este porcentaje relativamente bajo no impide que esta complicación contribuya directa e indirectamente …
Herramienta clínica para la búsqueda de biomarcadores de enfermedades neurológicas
2009
El solapamiento que presentan algunas enfermedades neurologicas en la clinica justifica la necesidad de establecer biomarcadores que sirvan como apoyo en el diagnostico y seguimiento de la enfermedad. El analisis de los fluidos intracraneales (sangre y liquido cefalorraquideo) juega un rol importante en la busqueda de estos biomarcadores. Las secuencias dinamicas de resonancia magnetica en contraste de fase (RM-CF) con sincronismo cardiaco permiten cuantificar el flujo de liquido cefalorraquideo (LCR) y de la sangre durante un ciclo cardiaco. No obstante, la medicion de flujo mediante secuencias de imagenes de RM-CF (IRM-CF) es precisa y reproducible siempre que se use un protocolo de adqui…

Effects of B-Cell Lymphoma on the Immune System and Immune Recovery after Treatment: The Paradigm of Targeted Therapy
2022
B-cell lymphoma and lymphoproliferative diseases represent a heterogeneous and complex group of neoplasms that are accompanied by a broad range of immune regulatory disorder phenotypes. Clinical features of autoimmunity, hyperinflammation, immunodeficiency and infection can variously dominate, depending on the immune pathway most involved. Immunological imbalance can play a role in lymphomagenesis, also supporting the progression of the disease, while on the other hand, lymphoma acts on the immune system to weaken immunosurveillance and facilitate immunoevasion. Therefore, the modulation of immunity can have a profound effect on disease progression or resolution, which makes the immune syst…
Moviments de dispersió en els primats. Variabilitat en els seus patrons i causes
2014
Els moviments de dispersió en els animals representen decisions crucials per als individus, ja que afecten la seua supervivència i èxit reproductiu, a més de ser un component important de la dinàmica poblacional. En aquest article es descriu la variabilitat en els patrons de dispersió en els primats i algunes de les causes, tant últimes com proximals, a les quals respon.
