Identification of Botanical Biomarkers in Argentinean Diplotaxis Honeys: Flavonoids and Glucosinolates

To select and establish floral biomarkers of the botanical origin ofDiplotaxis tenuifoliahoneys, the flavonoids and glucosinolates present in bee-deposited nectar collected from hive combs (unripe honey) and mature honey from the same hives fron which the unripe honey samples were collected were analyzed by LC-UV-PAD-ESI-MSn. Glycosidic conjugates of the flavonols quercetin, kaempferol, and isorhamnetin were detected and characterized in unripe honey.D. tenuifoliamature honeys contained the aglycones kaempferol, quercetin, and isorhamnetin. The differences between the phenolic profiles of mature honey and freshly deposited honey could be due to hydrolytic enzymatic activities. Aliphatic and indole glucososinolates were analyzed in unripe and mature honeys, this being the first report of the detection and characterization of glucosinolates as honey constituents. Moreover, these honey samples contained different amounts of propolis-derived flavonoid aglycones (1765−3171 μg/100 g) and hydroxycinnamic acid derivatives (29−1514 μg/100 g). Propolis flavonoids were already present in the freshly deposited nectar, showing that the incorporation of these compounds to honey occurs at the early steps of honey production. The flavonoids quercetin, kaempferol, and isorhamnetin and the glucosinolates detected in the samples could be used as complementary biomarkers for the determination of the floral origin of ArgentineanDiplotaxishoneys

Oliguria on the Day of Intubation Is Associated With Mortality in Patients With Acute Respiratory Distress Syndrome

To investigate the relationship between oliguric acute kidney injury (AKI) and mortality in patients with acute respiratory distress syndrome (ARDS). DESIGN: Retrospective cohort study. SETTING: This investigation took place at a single-center, tertiary referral multidisciplinary comprehensive healthcare hospital in metropolitan Detroit, Michigan. PATIENTS: Adult patients 18 years old or older hospitalized in the ICU and diagnosed with ARDS on mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Three hundred eight patients were included in the final analysis. Risk factors associated with mortality included advanced age (p \u3c 0.001), increased body mass index (p = 0.008), and a history of chronic kidney disease (p = 0.023). Presence of AKI by day 1 of intubation, with elevated creatinine (p = 0.003) and oliguria (p \u3c 0.001), was significantly associated with mortality. On multivariate analysis, advanced age (relative risk [RR], 1.02), urine output on the day of intubation (RR, 0.388), bicarbonate level (RR, 0.948), and Sequential Organ Failure Assessment severity score (RR, 1.09) were independently associated with mortality. A receiver operating characteristic curve identified a threshold urine output on the day of intubation of 0.7 mL/kg/hr (area under the curve, 0.75; p \u3c 0.001) as most closely associated with inpatient mortality (i.e., urine output \u3c 0.7 mL/kg/hr is associated with mortality). CONCLUSIONS: For patients with ARDS, oliguria on the day of intubation was independently associated with increased mortality. Urine output of less than 0.7 mL/kg/hr predicted 80% of inpatient deaths. These findings herald an augmented understanding of the role of urine output in medical decision-making and prognostication

Traceability of potential enterotoxigenic Bacillus cereus from bee-pollen samples from Argentina at different sampling throughout the production process

Bee-pollen is the result of the agglutination of pollen grains collected from flowers and mixed with nectar and salivary secretions by honeybees. Bee-pollen is a functional food sold for human and animal consumption but also is a favorable microhabitat for many spore-forming bacteria. Among them, Bacillus cereus is a ubiquitous Gram-positive spore-forming bacterium found in soil, plants, and enteric tracts of insects; these niches include honey and pollen. B. cereus can produce several toxins and other virulence factors causing an emetic or diarrheal syndrome after ingestion. This work aimed to study the traceability of potential enterotoxic Bacillus cereus based on colony counts, rep-fingerprinting and toxigenic profiles at four sampling points of the production proces

Irradiancia e irradiación UV-A a partir de medidas con radiómetros a 380 nm para aplicaciones ambientales de la energía solar

El correcto dimensionamiento de plantas de tratamiento por fotocatálisis solar requiere del conocimiento del recurso solar UV (280-400 nm) a nivel de la superficie terrestre. El UV-B (280-315nm), sólo constituye el 10% del total y se transmite sólo el 55% al ingresar al reactor, mientras que el UV-A(315-400 nm) se transmite en un 89%. En este trabajo se presenta y evalúa un método para calcular la irradiancia e irradiación UV-A a partir de mediciones a 380nm por medio del uso de un factor de escala dependiente del ángulo cenital solar. Los errores en la irradiancia calculada van del 18% a θ = 90º hasta 4% a θ =10º. El error en la irradiación UV-A calculada es del 10.2% para las integrales diarias. Estos errores están dentro del rango de incertidumbre aceptable para la mayoría de los sistemas fotocatalíticos solares y pueden ser usadas para los estudios de factibilidad.Proper dimensioning of plants for photocatalytic treatment of wastewaters require the knowledge of the UV solar resource availability. In this work, a method to calculate UV-A irradiance and irradiation from measurements at 380 nm by means of a scale factor dependant only on the solar zenith angle is proposed and evaluated. Errors in the calculated UV-A irradiance range from 18% at θ = 90º to 4% at θ =10º. Errors in the calculated UV-A irradiation are less than 11% for daily integrals. These errors are well within the range of acceptable uncertainty for most photocatalytic systems dimensioning and the procedure may be use for other applications as well. The next step is the establishment of relationships between UV-A and global solar radiation, and a map of the solar UV-A resource for Argentina.Asociación Argentina de Energías Renovables y Medio Ambiente (ASADES
