Abstract

fetched live from OpenAlex

OBJECTIVES: To evaluate the impact of the endothelial nitric oxide synthase (eNOS) gene on longitudinal development of blood pressure (BP) and left ventricular mass (LVM) from childhood into early adulthood. METHODS: Three polymorphisms including -922A>G, intron 4VNTR, and Glu298Asp of the eNOS gene were investigated. Individual growth-curve modeling and haplotype trend regression analyses were conducted for 579 white and black American youths with 12 assessments over a 15-year period. RESULTS: Significantly different allele and genotype frequencies were observed between blacks and whites for all three polymorphisms. Linkage disequilibrium (LD) patterns among these polymorphisms were also different between ethnic groups: strong LD between the -922A>G and intron 4 VNTR loci was observed in whites but not in blacks. Single locus analyses identified a significant interaction between the intron 4 VNTR and gender on diastolic BP (DBP) levels. The 4a allele carriers had significantly lower DBP levels in males (P=0.012), but higher DBP levels in females (P=0.045). Haplotype analyses confirmed the DBP lowering effect in males (P=0.049). DBP in males homozygous for haplotype G-4a-Glu was 2.58 mmHg lower than males homozygous for the most common haplotype (A-non4a-Glu). Additionally, individuals homozygous for haplotype G-non4a-Glu showed a 0.51 mmHg steeper increase in DBP per year with age as compared to the most common haplotype (P=0.007). No associations between single polymorphisms or haplotypes of the eNOS gene and systolic BP or LVM were found. CONCLUSIONS: our results suggest that eNOS gene may have gender-specific and age-dependent effects on DBP and the development of hypertension risk.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
