Dry eye is matched by increased intrasubject variability in tear osmolarity as confirmed by machine learning approach El ojo seco está relacionado con un aumento intrasujeto de la variabilidad de osmolaridad lagrimal confirmado por tecnología de aprendiza
(Elsevier Ltd, 2019)
Objective: Because of high variability, tear film osmolarity measures have been questioned in dry eye assessment. Understanding the origin of such variability would aid data interpretation. This study aims to evaluate ...
¿Están los CLC de Leishmania asociados con la adaptación del parásito a cambios de pH y/o de osmolaridad?
(Universidad Nacional de Colombia - Sede Bogotá - Faculdad de Ciencias - Departamento de Biología, 2016-02-01)
Leishmania es un protozoario patógeno, que transita durante su ciclo de vida desde el intestino de su vector hasta un compartimiento fagolisosomal al interior de su célula hospedera, el macrófago. Durante este recorrido ...
SPI-9 of Salmonella enterica serovar Typhi is constituted by an operon positively regulated by RpoS and contributes to adherence to epithelial cells in culture
(Microbiology Soc, 2016)
The genomic island 9 (SPI-9) from Salmonella enterica serovar Typhi (S. Typhi) carries three ORFs (STY2876, STY2877, STY2878) presenting 98% identity with a type 1 secretory apparatus (T1SS), and a single ORF (STY2875) ...
Effect of two semen collection in a breeding season on the seminal quality of red-bellied pacu (Piaractus brachypomus)
(2019)
Se evaluó el efecto de dos colectas de semen realizadas en la misma temporada reproductiva sobre los parámetros espermáticos y composición fisicoquímica del plasma seminal de Piaractus brachypomus. El semen de nueve machos ...
Electrophysiological characterization of potassium conductive pathways in Trypanosoma cruzi
(2011)
Potassium channels (K+ channels) are members of one of the largest and most diverse families of membrane proteins, widely described from bacteria to humans. Their functions include voltage-membrane potential maintenance, ...
Síndrome de resección transuretral de próstata. revisión de conceptos
(Facultad de Medicina. Universidad Nacional de Colombia. Sede Bogotá, 2009)
Desde que el síndrome de resección transuretral de próstata (SRTUP) fue descrito hace casi sesenta años su reconocimiento y su entendimiento han abarcado un importante acervo dentro de la literatura médica mundial. A pesar ...
The rfaH gene, which affects lipopolysaccharide synthesis in Salmonella enterica serovar Typhi, is differentially expressed during the bacterial growth phase
(Elsevier Sciences B. V., 2001)
We have cloned and sequenced the rfaH gene from Salmonella enterica serovar Typhi Strain Ty2. The gene shoed a high degree of similirity to the rfaH genes from Escherichia coli K-12 and S. enterica serovar Typhimurium. A ...

La insuficiencia renal aguda se diagnostica aproximadamente en 5% de los pacientes
hospitalizados. Sus principales causas se relacionan con la alteración del flujo sanguíneo
renal, sea por depleción de volumen, baja ...
Deprivation of Na +, Ca 2+ and Mg 2+ from the extracellular solution increases cytosolic Ca 2+ and stimulates catecholamine secretion from cultured bovine adrenal chromaffin cells
(1997)
We report here that exposing cultured chromaffin cells to a low ionic strength medium (with sucrose in place of NaCl to maintain osmolarity) can induce a marked elevation in cytosolic Ca 2+ concentration ([Ca 2+](i)) and ...
Comparison of Recommendations in Clinical Practice Guidelines for Acute Gastroenteritis in Children
(2016)
Objective: Acute gastroenteritis (AGE) is a major cause of child mortality and morbidity. This study aimed at systematically reviewing clinical practice guidelines (CPGs) on AGE to compare recommendations and provide the ...
