PROBLEM: Question: Do associations of Heart Rate With Inflammatory Markers Are Modulated by Gender and Obesity in Older Adults?
Answer: Faster HR is associated with proinflammatory state in elderly patients; this association seems to be limited to women with higher BMI.

SOLUTION: yes

PROBLEM: Question: Are higher maternal serum concentrations of nicotinamide and related metabolites in late pregnancy associated with a lower risk of offspring atopic eczema at age 12 months?
Answer: This is the first study linking maternal serum concentrations of nicotinamide and related metabolites to the risk of atopic eczema in the offspring. The findings point to potentially modifiable maternal influences on this complex and highly prevalent condition.

SOLUTION: yes

PROBLEM: Question: Is cXCR4 highly expressed at the tumor front but not in the center of prostate cancers?
Answer: CXCR4 seems overexpressed at the tumor front of prostate tumors, where it potentially promotes cell migration toward the SDF-1 centrifugal attracting gradient, as well as epithelial-mesenchymal transition. High CXCR4 and low SDF-1 levels at tumor front were both associated with adverse histological features.

SOLUTION:
yes
