OBJECTIVES: Essential hypertension is known to be associated with growth, development, and aging of humans. Telomeres are specialized nucleoprotein complexes consisting of tandem repeats of DNA sequences (TTAGGG)n that serve as protective caps of human chromosomes. Telomere length is considered as a biomarker of aging in somatic cells. In the ...

Recent studies have shown that hypertension is inversely correlated with bone mineral density (BMD) as determined by dual energy x-ray absorptiometery (DXA) in different ethnic groups. But in most published studies, either the sample size was small or the study was limited by different measurement methods. These limitations leave this ...

Acromegaly has several cardiovascular manifestations of which cardiomyopathy (CMP) and hypertension (HTN) are important and contribute to the increased mortality associated with the disease. Both these manifestations are reversible with treatment. However, very advanced CMP with severe systolic dysfunction has low likelihood of reversal. The reversibility is higher in young ...

Salt-based aging plays an important part in the realism of scenes featuring stone structures and monuments. A proposed model, based on physical behaviors and principles, replaces the simulation of complex physical formulations with ad hoc algorithms. It leads to plausible results, ultimately helping designers create aging patterns on affected objects.

BACKGROUND: Advanced glycation end products (AGEs) are produced by non-enzymatic glycation or glycoxidation of proteins, lipids and nucleic acids. The bond of AGEs and the receptor of AGE (AGER) in a pro-oxidant environment could induce immune and inflammation reaction involved in progress of microvascular disease. Accumulated evidence warrant further study ...

BACKGROUND AND PURPOSE:IAs are found in 2.3% of adults; the mean age at detection is 52 years. Prevalence is <0.5% in young adults. Early studies suggest that 10%-50% of patients with aortic coarctation have IAs. Screening recommendations are variable. We sought to examine the prevalence of IAs through screening with ...

Excess body fat deposited viscerally rather than elsewhere in the body is associated with higher risk for hypertension; this relationship is stronger in men than in women. Here we investigated whether similar sex dimorphism exists already in adolescence. A population-based sample of adolescent boys (n=237) and girls (n=262), age 12 ...

Aging is associated with changes in arterial wall structure and function that exceed physiological adaptation, with an increased risk of cardiovascular events. The most consistent structural changes are luminal enlargement (dilatation), wall thickening (remodeling), and a reduction of elastic properties. Endothelial dysfunction plays an important role in the functional changes ...
