Association of composite dietary antioxidant index with prevalence of stroke: insights from NHANES 1999-2018.

Background: There is a growing acknowledgment of the potential influence of antioxidative effects resulting from dietary decisions on the occurrence of stroke. The objective of this study was to elucidate the correlation between the composite dietary antioxidant index (CDAI) and the incidence of stroke in the general population of the United States.

Methods: We gathered cross-sectional data encompassing 40,320 participants from the National Health and Nutrition Examination Survey (NHANES) spanning the years 1999 to 2018.

Transcriptome-wide identification of NAC (no apical meristem/Arabidopsis transcription activation factor/cup-shaped cotyledon) transcription factors potentially involved in salt stress response in garlic.

Soil salinity has been an increasing problem worldwide endangering crop production and human food security. It is an ideal strategy to excavate stress resistant genes and develop salt tolerant crops. NAC (no apical meristem/Arabidopsis transcription activation factor/cup-shaped cotyledon) transcription factors have been demonstrated to be involved in salt stress response.

[Spectral characteristic parameters estimation models for potassium content of Juglans regia 'Wen185' leaves.].

According to the field trials with quantitative fertilization, the spectral characteristic parameters which were highly significantly correlated with foliar potassium (K) content were screened out using Pearson correlation analysis, and the foliar K content estimation models of Juglans regia 'Wen185' in different phenological periods of fruit development were built up with these parameters as independent variables using regression analysis. The results showed that there were one or more spectral characteristic parameters which were highly significantly correlated with the foliar K contents of 'Wen185' walnut in the different phonological periods of fruit development (P＜0.01).

[Models for estimating foliar Fe and Mn Concentration of Armeniaca vulgaris cv. Luntaibaixing using spectral reflectance].

Aimed at providing technology for a rapid nutrition diagnosis system of micronutrients in Armeniaca vulgaris cv. Luntaibaixing, we established an element concentration estimation model for its foliar ferrum (Fe) and manganese (Mn) concentration based on spectrum analysis. The foliar spectrum reflectance at various phenological periods of fruit development under different soil fertility conditions was measured by Unispec-SC spectrometer.
