Although being classified as autoimmune connective tissue disease, dominant components of the pathophysiology of systemic sclerosis (SSc) consists of mechanisms of vascular damage, which can occur early in the course of the disease. Amongst them are abnormal vasoreactivity, hypoxia, insufficient neoangiogenesis and direct damage of vascular and perivascular cells. They result in a decreased cap...

Angiotensin (Ang) II is considered a regulatory hormone stimulating vascular smooth muscle cell constriction, aldosterone release from the adrenal gland, and sodium reabsorption in the renal tubule. Furthermore, Ang II may be formed and act locally as a chemokine, inducing tyrosine phosphorylation, cell growth, hypertrophy, and differentiation. In addition, evidence has recently accrued showing...

Ultrashort laser pulses have been adapted for use in a variety of applications from micromachining of dielectrics to atmospheric spectrochemistry and multiphoton microscopy. These lasers emit almost exclusively in the retinal hazard wavelength regime, making them potential sources for accidental vision loss, but also candidates for biomedical applications where precise alteration of tissues is ...

Perfluorinated compounds (PFCs) such as perfluorooctanesulfonate (PFOS) are stable chemicals that accumulate in biological matrix. Toxicity of these compounds including immunotoxicity has been demonstrated in experimental models and wildlife. Although limited number of studies examined the effects of PFOS on human lymphocytes but so far no research has investigated the complete mechanisms of PF...
