AI Article Synopsis
- Sunflower seeds are increasingly recognized as a common allergen-free alternative to peanuts, but they can also cause allergies.
- A study conducted over 26 years identified 235 pediatric patients with sunflower seed allergy, primarily diagnosed at around 3.9 years old, and most had other related allergy conditions.
- The study found that the incidence of sunflower seed allergies rose over time, with an annual increase of 21%, and reactions often ranged from mild skin issues to severe anaphylactic responses.
Article Abstract
Background: Sunflower seeds are a popular allergen-free peanut alternative.
Objective: To describe sunflower seed allergy incidence and characteristics.
Methods: We conducted a retrospective cohort study of patients with sunflower seed allergy from 1995 to 2021 in a pediatric allergy clinic. We described demographic characteristics, testing results, atopic comorbidities, and reaction histories of patients with sunflower seed allergy and calculated the annual cumulative incidence of the allergy. Logistic regression was used to estimate the increase in odds of sunflower seed allergy diagnosis for each year from 1995 to 2021.
Results: From 1995 to 2021, we identified 235 patients with sunflower seed allergy. Among patients with sunflower seed allergy, the median age at diagnosis was 3.9 years. More than three-quarters of patients had another atopic condition. Half of the reactions consisted of mild urticaria or rash, and a quarter met criteria for anaphylaxis. The cumulative incidence ranged from 0% (1995-1999, 2001-2004, and 2006) to 0.38% (2021). From 1995 to 2021, the odds of sunflower seed allergy diagnosis increased annually by 21% (odds ratio, 1.21; 95% CI, 1.17-1.25).
Conclusions: In our single-center cohort of children with sunflower seed allergy, most children were diagnosed in early childhood, had high rates of comorbid atopic conditions, and had high rates of cutaneous reactions to sunflower seed products. Moreover, in our cohort, incidence of sunflower seed allergy increased.

The Pseudomonas aeruginosa LasR quorum sensing system (QSS) is central to regulating the expression of several pathogenicity factors. Also, while seed- and/or plant-derived products have been investigated as QSS regulators, the impact of Helianthus annuus (Pannar sunflower seed cultivars) extracts and metabolites as LasR modulators remain underexplored. Thus, this study focused on the untargeted metabolomic profiling (Liquid Chromatography-Mass Spectrometry), in vitro and in silico (docking, pharmacokinetics, dynamic simulation) bioprospection of Pannar seed cultivars' extracts and metabolites as LasR modulators.

Article Synopsis
- Sunflower yields are negatively affected by water deficiency, making effective irrigation, cultivar selection, and silica gel application crucial for better growth and production.
- A field experiment in Luxor, Egypt tested different irrigation levels, sunflower cultivars, and silica gel treatments over two seasons, revealing significant impacts of irrigation and cultivar on growth traits, with silica gel enhancing key parameters like oil yield.
- Combining moderate irrigation with silica gel treatment significantly improved water productivity and sunflower output, demonstrating the effectiveness of tailored agronomic strategies for sustainable crop management under varying environmental conditions.

Article Synopsis
- - The study analyzed soil selenium content and bioavailability in 1,985 soil samples and 120 crop/root samples from the Hetao Plain, revealing that about 5.59% of soil exceeded contamination risk values, but heavy metal levels in crops were low overall.
- - Selenium in the soil showed significant local enrichment and varied in availability, primarily influenced by natural factors; the forms of selenium were ranked by availability, with residues being the most available for plant absorption.
- - Key factors like soil texture, organic matter, and pH were found to influence selenium levels, where clay soil and high organic content could increase selenium accumulation but restrict its activity for plant uptake.

Temperature is the main environmental determinant of seed oil fatty acid Q9 composition. There are no models describing common responses of main seed oil fatty acids to temperature in plants. The aim of thus work was to investigate common responses of seed oil fatty acids to minimum temperature during grain filling across species and genotypes.
