Modulation of charge carrier density in condensed materials based on ionic/electronic interaction has attracted much attention. Here, protonic/electronic hybrid indium-zinc-oxide (IZO) transistors gated by chitosan based electrolyte were obtained. The chitosan-based electrolyte illustrates a high proton conductivity and an extremely strong proton gating behavior. The transistor illustrates good electrical performances at a low operating voltage of ∼1.0 V such as on/off ratio of ∼3 × 107, subthreshold swing of ∼65 mV/dec, threshold voltage of ∼0.3 V, and mobility of ∼7 cm2/V s. Good positive gate bias stress stabilities are obtained. Furthermore, a low voltage driven resistor-loaded inverter was built by using an IZO transistor in series with a load resistor, exhibiting a linear relationship between the voltage gain and the supplied voltage. The inverter is also used for decreasing noises of input signals. The protonic/electronic hybrid IZO transistors have potential applications in biochemical sensors and portable electronics.

Guo y col describieron mayor concentración de MMP-1 en el tejido de placas rotas frente a las no rotas 10 . Todos estos estudios encontraron asociación entre la presencia de aterosclerosis, placas rotas o con cápsula adelgazada, con los niveles de MMP-1, pero a nivel histológico.…”

“…La metaloproteinasa-1 (MMP-1) tiene como principal sustrato al colágeno tipo I, responsable de la fuerza elástica de los tejidos. Se ha demostrado una gran expresión histológica de MMP-1 en placas ateroscleróticas carotídeas y coronarias, sobre todo en aquellas que estaban rotas 9,10 . También se han correlacionado sus niveles en sangre circulante con la presencia de enfermedad coronaria 11,12 .…”

Fundamento. Las placas ateroscleróticas que producen la mayoría de los síndromes coronarios agudos al romperse son los fibroateromas de cápsula fina, denominados placas vulnerables. Éstas pueden ser detectadas únicamente con técnicas invasivas de imagen intracoronaria. Es preciso encontrar un biomarcador no invasivo que permita identificar a los pacientes con estas placas sin necesidad de cateterismo cardiaco. La metaloproteinasa-1 es una enzima involucrada en el metabolismo de la matriz extracelular que ha sido relacionada con la ruptura de las placas ateroscleróticas. Se desconocen sus niveles séricos en pacientes con placas vulnerables. Material y métodos.Se incluyeron pacientes sometidos a cateterismo cardiaco por enfermedad coronaria estable. Se estudiaron las arterias coronarias con tomografía de coherencia óptica para detectar placas vulnerables. Se extrajeron muestras de sangre periférica y del seno coronario para analizar la concentración de metaloproteinasa-1.resultados. Se incluyeron 51 pacientes. Trece tenían al menos un fibroateroma de cápsula fina. No se encontraron diferencias significativas en las características clínicas, perfil lipídico ni proteína C reactiva entre los pacientes con y sin placas vulnerables. Los pacientes con placas vulnerables presentaron concentraciones significativamente mayores de metaloproteinasa-1, tanto en sangre periférica (7330±5541 vs 2894±1783 pg/ml, p=0,025) como en seno coronario (6012±3854 vs 2707±1252 pg/ml, p=0,047).conclusiones. Los pacientes con placas vulnerables presentaron niveles séricos significativamente mayores de metaloproteinasa-1. Se requieren estudios con seguimiento clínico para evaluar el valor pronóstico de la metaloproteinasa-1 sérica.Palabras clave: Placa vulnerable. Fibroateroma de cápsula fina. Biomarcador.

“…Reported flavonoid aglycones in D. odorifera are isoflavones, neoflavones, isoflavanones, flavanones, chalcones, isoflavanonol and pterocarpan. More literatures pay attention to the isolation [12][13][14], LC-MS/MS analysis [15] and determination [16,17] of flavonoids in D. odorifera, but few reports focus on the sample pretreatment. So it is not easy to identify trace flavonoid glycosides due to their low concentration in complex matrix.…”

“…So it is not easy to identify trace flavonoid glycosides due to their low concentration in complex matrix. As we know, 6-C-glycopyranosyl luteolin and isohemiphloin have been isolated from D. odorifera [18]. For such minor compounds, it is necessary to selectively separate them in order to minimize the interference of the high concentration compounds in separation and detection.…”

Dalbergia odorifera contains high concentrations of flavonoid aglycones and trace flavonoid glycosides. In this study, trace flavonoid glycosides were separated from D. odorifera by titania with matrix solid-phase dispersion (MSPD). Before the MSPD experiment, four standards, including two isoflavone glycosides (genistin and formononetin-8-C-apiosyl (1-6)-glucoside) and their aglycones (genistein and formononetin), were used to compare their retention on a titania column. The effect of acetonitrile concentration and pH on their retention was investigated and a conclusion was drawn that high acetonitrile concentration and pH lead to the greatest difference in the retention of flavonoid as glycosides and aglycones. Besides hydrophilic interaction and ligand-exchange interaction may exist between sugar moiety of flavonoid glycoside and titania, so that flavonoid glycosides have stronger retention than that of aglycones. Based on the chromatographic rule of flavonoid as glycosides and aglycones on the titania column, the MSPD method was optimized to elute high concentration flavonoid aglycones first with 90% acetonitrile and 10% water containing 100 mM ammonium acetate buffer, and then to elute trace flavonoid glycosides with 20% acetonitrile and 80% water containing 1% trifluoroacetate (TFA). Isolated flavonoid glycosides were further analyzed by UPLC-MS/MS, and their fragmentation in MS 2 showed they are C-glycosyl flavonoids.
