Recent studies have shown a relationship between elevated levels of homocysteine and vascular disease including cerebrovascular accidents and myocardial infarctions.
Various studies have shown a relationship between elevated levels of inhalable particulate matter (PM) and agricultural practices, especially in the vicinity of agricultural fields.
The harmful effects of homocysteine on blood vessels and blood clotting may also explain the link between elevated levels of this amino acid and various pregnancy complications, including repeated early miscarriage; pre-eclampsia, or pregnancy-related hypertension; premature birth; very low birth weight; and certain birth defects.
In agreement with studies from other petroliferous basins, our results show significant correlations between elevated levels of radiogenic [4 He], thermogenic [CH4 ], and dissolved ions (e.g., Cl, Br, Sr, Ba).
Thomsen et al. measured the relationship between elevated levels of three inflammatory biomarkers (CRP, fibrinogen, and leukocyte count) and comorbidities in a cohort of 8,656 patients with COPD [66].
Studies have shown a link between elevated levels of coke dust in the air and the deaths of people with respiratory illness and heart disease.
This work shows a direct connection between elevated levels of corticosterone and the sex ratio of resultant offspring, leading researchers to conclude that corticosterone may directly influence sex chromosome segregation during meiosis, or may lead to differential maturation rates of differentially sexed ova.
A correlation between elevated levels of soluble CD14 in serum and complicated P. falciparum malaria in humans has previously been reported [34].
To contest this hypothesis, we measured MG levels in macrophages during mycobacterial infection, characterized MG-induced apoptosis, and ascertained the relationship between elevated levels of MG/AGE and macrophage functions during mycobacterial infection.
Some of these studies concluded that CCR5 ligands may exert protective role in HIV-1/SIV infection [13], [16] [18], while others suggested an association between elevated levels of CCR5 ligands and HIV disease progression [14], [15].
There is an association between elevated levels of inflammatory markers and self-rated health.
