Systemic vascular resistance predicts the development of hypertension : the cardiovascular risk in young Finns study

To study whether systemic hemodynamics, especially systemic vascular resistance, predicts the development of hypertension and improves the risk prediction of incident hypertension beyond common risk factors in the risk models in young adults. Typical risk factors for hypertension in the risk prediction models (systolic and diastolic blood pressure, parental history of hypertension, age, sex, body-mass index, smoking), laboratory values (high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, glucose, insulin, C-reactive protein), heart rate (HR), stroke index (SI), and systemic vascular resistance index (SVRI) calculated by whole-body impedance cardiography…

Influence of early life risk factors and lifestyle on systemic vascular resistance in later adulthood : the cardiovascular risk in young Finns study

Purpose: There are limited data available concerning the effects of lifetime risk factors and lifestyle on systemic hemodynamics, especially on systemic vascular resistance. The purpose of the study was to evaluate how lifetime cardiovascular risk factors (body mass index (BMI), high-density lipoprotein, low-density lipoprotein, triglycerides, systolic blood pressure, blood glucose) and lifestyle factors (vegetable consumption, fruit consumption, smoking and physical activity) predict systemic vascular resistance index (SVRI) and cardiac index (CI) assessed in adulthood. Materials and Methods: Our study cohort comprised 1635 subjects of the Cardiovascular Risk in Young Finns Study followed …

Novel α2β1 integrin inhibitors reveal that integrin binding to collagen under shear stress conditions does not require receptor preactivation.

The interaction between α2β1 integrin (GPIa/IIa, VLA-2) and vascular collagen is one of the initiating events in thrombus formation. Here, we describe two structurally similar sulfonamide derivatives, BTT-3033 and BTT-3034, and show that, under static conditions, they have an almost identical effect on α2-expressing CHO cell adhesion to collagen I, but only BTT-3033 blocks platelet attachment under flow (90 dynes/cm(2)). Differential scanning fluorimetry showed that both molecules bind to the α2I domain of the recombinant α2 subunit. To further study integrin binding mechanism(s) of the two sulfonamides, we created an α2 Y285F mutant containing a substitution near the metal ion-dependent ad…

Association of lifetime blood pressure with adulthood exercise blood pressure response: the cardiovascular risk in young Finns study

Elevated blood pressure (BP) in childhood has been associated with increased adulthood BP. However, BP and its change from childhood to adulthood and the risk of exaggerated adulthood exercise BP response are largely unknown. Therefore, we studied the association of childhood and adulthood BP with adulthood exercise BP response. This investigation consisted of 406 individuals participating in the ongoing Cardiovascular Risk in Young Finns Study (baseline in 1980, at age of 6–18 years; follow-up in adulthood in 27–29 years since baseline). In childhood BP was classified as elevated according to the tables from the International Child Blood Pressure References Establishment Consortium, while …

Molecular mechanism of α2β1 integrin interaction with human echovirus 1

Conformational activation increases the affinity of integrins to their ligands. On ligand binding, further changes in integrin conformation elicit cellular signalling. Unlike any of the natural ligands of alpha2beta1 integrin, human echovirus 1 (EV1) seemed to bind more avidly a 'closed' than an activated 'open' form of the alpha2I domain. Furthermore, a mutation E336A in the alpha2 subunit, which inactivated alpha2beta1 as a collagen receptor, enhanced alpha2beta1 binding to EV1. Thus, EV1 seems to recognize an inactive integrin, and not even the virus binding could trigger the conformational activation of alpha2beta1. This was supported by the fact that the integrin clustering by EV1 did …
