This was associated with an increased serum creatinine and a decrease in glomerular filtration rate, arteriolar lesions and arterial hypertension.
11,12,13) In our case series, we noted isolated unilateral neuroretinitis in 2 patients, neuroretinitis with serous retinal detachment in the inferior quadrant in 1 patient, and unilateral neuroretinitis with contralateral retinal infiltrate and subsequent inferotemporal branch arteriolar occlusion in 1 patient.
Acute CsA induced nephrotoxicity is characterised by arteriolar hyalinisation and stripped tubular necrosis and interstitial infilteration.
Besides investigating the direct influence of EC on HSC in different vascular niches, the interaction of EC with perivascular MSC and particularly neurons will be compared between the sinusoidal and arteriolar niche under steady-state and malignant conditions.
Tubulo-glomerular feedback is a normal intra-renal mechanism whereby increased solute delivery to distal tubule results in afferent arteriolar vasoconstriction.
Mean pulmonary capillary wedge pressure was 20 mmHg and pulmonary arteriolar resistance was 58 dynes.
Alpha-1 blockage leads to direct arteriolar dilatation, which results in an increased blood flow and decreased outflow secondary to effacement and subsequent obstruction of emissary veins.
In compensation, flow is redistributed in accordance with arteriolar and capillary resistance, rheological factors, and the tissue demand for oxygen.
Vascular parameters such as venule dilation and larger retinal arteriolar calibre [9, 10], changes to the vasculature shapes and arteriolar branching angle, increased tortuosity [11-13], and Fractal Dimension (FD) of the retinal vascular network [14-16] are associated with DR.
The XOR products together with the oxidants generated by NAD(P)H oxidase and NO synthase may also modulate another endothelial cell function, the regulation of arteriolar tone via NO production, which has local and systemic vasodilating activity and causes XOR inhibition (Figure 2(b)).
Aunque el VEGF es el mayor protagonista, tambien se han implicado otras sustancias vasoactivas como interleuquinas: IL-1, IL-2, IL-6, IL-8, endotelina 1, factor de necrosis tumoral alfa y prostaglandinas que estan asociadas con una vasodilatacion arteriolar simultanea y la ocurrencia de disfuncion circulatoria hiperdinamica que activa al sistema nervioso simpatico, sistema renina angiotensina aldosterona y hormona antidiuretica (3, 4).
