Abstract Introduction: dysphagia is a common complication of stroke, and serum albumin is widely recognized as a strong prognostic marker of health and/or disease status. However, the correlation between dysphagia and serum albumin levels has not been established. Objectives: to observe the correlation between dysphagia and serum albumin levels and prognosis in patients with stroke. Methods: we performed a retrospective study of patients hospitalized between June 1, 2018, and June 1, 2022. A total of 1,370 patients were enrolled. The patients were divided into two groups: dysphagia and non-dysphagia. Binary logistic regression and multiple linear regression models were used to analyze the correlation between dysphagia, albumin, modified Rankin Scale (mRS), activities of daily living (ADL), and length of hospital stay (LOS). Results: after adjusting for confounding factors, the risk of pneumonia in the dysphagia group was 2.417 times higher than that in the non-dysphagia group (OR = 2.417, 95 % CI: 1.902-3.072, p = 0.000). The risk of mRS ≥ 3 and modified Barthel index (MBI) < 60 in patients with dysphagia was 3.272-fold (OR = 3.272, 95 % CI: 2.508-4.269, p < 0.001) and 1.670-fold (OR = 1.670, 95 % CI: 1.230-2.268, p < 0.001), respectively; and the risk of hypoproteinemia was 2.533 times higher (OR = 2.533, 95 % CI: 1.879-3.414, p = 0.000). Stepwise linear regression showed that dysphagia was significantly correlated with lower albumin levels and higher mRS, lower ADL, and longer LOS in patients with stroke (β = -0.220, β = 0.265, β = -0.210, and β = 0.147, respectively; p < 0.001). Conclusions: dysphagia in patients with stroke is associated with decreased albumin levels and has an impact on its prognosis.

Resumen Introducción: la disfagia es una complicación común del accidente cerebrovascular, y la albúmina sérica es ampliamente reconocida como un fuerte marcador pronóstico del estado de salud y/o enfermedad. Sin embargo, no se ha establecido la correlación entre la disfagia y los niveles de albúmina sérica. Objetivos: observar la correlación entre la disfagia y los niveles de albúmina sérica y el pronóstico en pacientes con accidente cerebrovascular. Métodos: realizamos un estudio retrospectivo de pacientes hospitalizados entre el 1 de junio de 2018 y el 1 de junio de 2022. Se inscribieron un total de 1.370 pacientes, los cuales fueron divididos en dos grupos: con disfagia y sin disfagia. Se utilizaron modelos de regresión logística binaria y de regresión lineal múltiple para analizar la correlación entre la disfagia, la albúmina, la escala de Rankin modificada (ERm), las actividades de la vida diaria (AVD) y el tiempo de estancia hospitalaria (TEH). Resultados: después de ajustar por factores de confusión, el riesgo de neumonía en el grupo de disfagia fue 2,417 veces mayor que en el grupo sin disfagia (OR = 2,417, IC 95 %: 1,902-3,072, p = 0,000). El riesgo de ERm ≥ 3 y el índice de Barthel modificado (MBI) < 60 en pacientes con disfagia se multiplicó por 3,272 veces (OR = 3,272, IC 95 %: 2,508-4,269, p < 0,001) y 1,670 veces (OR = 1,670, IC 95 %: 1,230-2,268, p < 0,001), respectivamente; el riesgo de hipoproteinemia fue 2,533 veces mayor (OR = 2,533, IC 95 %: 1,879-3,414, p = 0,000). La regresión lineal por pasos mostró que la disfagia se correlacionó significativamente con niveles más bajos de albúmina y ERm más altos, AVD más bajos y TEH más prolongados en pacientes con accidente cerebrovascular (β = -0,220, β = 0,265, β = -0,210 y β = 0,147, respectivamente; p < 0,001). Conclusiones: la disfagia en pacientes con accidente cerebrovascular se asocia a una disminución de los niveles de albúmina y repercute en su pronóstico.

ABSTRACT Finger citron (Citrus medica L. var. sarcodactylis (Hoola van Nooten) Swingle; Rutaceae: Citrus) is an important plant for both medicine and food. Due to the lack of suitability analysis, many problems have arisen in its planting. According to the daily observation data, Kriging interpolation was selected to spatialize precipitation and temperature data. MaxEnt and ArcGIS were applied to simulate the suitable areas of finger citron in China from the perspectives of bioclimate, soil, topographic factors and human activities in 2050s and 2090s. Results showed that temperature annual range (Bio7), annual precipitation (Bio12), human footprint (Hf), elevation (El) and precipitation seasonality (Bio15) were identified as the dominant environmental variables related to the distribution of finger citron. Spatiotemporal distribution of annual precipitation (Bio12) showed that in the future, the precipitation in South China tends to decrease first (2050s) and then increase (2090s). The spatio-temporal analysis of temperature annual range (Bio7) showed that the 20-30 ℃ region was relatively stable in the Sichuan Basin and the middle and lower reaches of the Pearl River Basin. Under the future climate change scenarios, the total suitable area showed a significant increase trend in 2090s, and the change of most, moderately and poorly suitable habitats showed no obvious law. Under SSP1-2.6, SSP2-4.5 and SSP5-8.5 scenarios, the centroid of the most suitable habitat of finger citron would move to the northwest, southeast and southwest respectively. Our results can effectively carry out to promote the recovery of its population.

RESUMO: Peonia, Feng dan’ (Paeonia ostia) do género Paeonia (o grupo lenhoso) é recomendado como uma nova cultura promissora na produção de óleos, devido aos elementos nutritivos na semente, no entanto, o desenvolvimento desta nova cultura está agora limitado devido às baixas taxas de fixação de sementes. Este estudo tem por objetivo identificar meios de melhorar a polinização cruzada de ‘Feng dan’ como o parental paterno, por ser uma cultura de óleo adequada, de modo a melhorar as taxas de fixação de sementes de ‘Feng dan’, e para prever a relação funcional entre o vigor do pólen e as taxas de fixação de sementes para melhorar a eficiência da experiência de polinização. Em primeiro lugar, foram realizados três passos para analisar o método de medição do vigor do pólen do pai paternal, que poderia ter uma relação forte com as taxas de fixação das sementes. Em segundo lugar, obter as taxas de fixação de sementes correspondentes por polinização cruzada. Em terceiro lugar, foi estabelecida a relação funcional entre dois índices que poderiam ser utilizados na prática da polinização cruzada. Os resultados indicaram que os melhores parentais paternos de ‘Feng dan’ eram cultivares de ‘Feng dan’ de outras populações de cultivo diferentes. A concentração de meio mais adequada para a germinação do pólen foi 100~150 g/L de sacarose, 0,06~0,08 g/L ácido bórico, e 50~200 g/L PEG-6000. Tanto a taxa de estabelecimento das sementes como o número de sementes foram positivamente correlacionados com a atividade do pólen, e a taxa de estabelecimento das sementes foi negativamente correlacionada com a precipitação local.

ABSTRACT: Paeonia ostii ‘Feng dan’ is recommended as a new promising oil crop because of the nutrient elements in its seed; however, the development of this new oil crop is now limited due to its low seed setting rate. This study identified ways to improve the cross pollination of Feng dan as the maternal parent, which has been proved to be a suitable oil crop, so as to improve the seed setting rate of ‘Feng dan’, and to predict the functional relationship between pollen vigor and seed setting rate. improving the efficiency of cross pollination. Three major steps were conducted, first, to screen the appropriate method of measuring pollen vigor of the paternal parent, which could have a strong relationship with seed setting rate. Second, to obtain the corresponding seed setting rate by cross pollination. Third, the functional relationship between two indexes was founded which could be used in cross pollination practice. Results indicated that the best paternal parents of ‘Feng dan’ were ‘Feng dan’ cultivars from other different cultivation populations; The most suitable medium concentration for pollen germination was 100~150 g/L sucrose, 0.06~0.08 g/L boric acid, and 50~200 g/L PEG-6000. Both the seed setting rate and the number of seed grains were positively correlated with the pollen activity, and the seed setting rate was negatively correlated with the local precipitation.

Antibacterial activity of the compounds against Staphylococcus aureus, Escherichia coli, and Klebsielle pneumoniae strains was studied. Compounds 1 and 2 have moderate minimum inhibition concentration values on the tested bacteria strains. Compound 3, with the Br-substituent groups, showed the highest activity on the bacterial strains.

Background Industrial food processing induces protein glycation modifications and toxic advanced glycation end products (AGEs) which affect human health. Therefore, it is of interest to monitor AGEs in food processing. The present study was carried out to investigate the influence of lotus seedpod oligomeric procyanidin (LSOPC) concentrations, solution pH value and metal ions on AGE formation by heat treatment of lactose-lysine model solutions. Ne-(carboxymethyl) lysine (CML), as one of the common AGEs was also determined by HPLC-MS/MS in this experiment. Results The results showed that LSOPC can inhibit the formation of AGEs effectively at higher concentrations, lower temperature, and it can reverse the promotion function of metal ions because of its high inhibition activity. Also, LSOPC can inhibit CML formation in the Maillard reaction as well. Conclusion These results indicated that LSOPC could be used as functional food ingredients to inhibit AGE formation.
