Vesicular stomatitis virus (VSV) was used as a model virus to study the processes involved in photoinactivation by aluminum phthalocyanine tetrasulfonate (AIPcS(4),) or silicon phthalocyanine HOSiPcOSi(CH3)(2)(CH2)(3)N(CH3)(2) (Pc4) and red light. Pr

Merocyanine 540 (MC540)-mediated photodynamic damage to erythrocytes was strongly reduced when illumination was performed at pH 8.5 as compared to pH 7.4. This could be explained by high pH-mediated hyperpolarization of the erythrocyte membrane, resu

Illumination of erythrocytes in the presence of merocyanine 540 (MC540) resulted in changed binding characteristics of MC540, i.e. a red shift in the emission maximum of bound dye with an increase in the relative fluorescence quantum yield. Aluminum

— It has been shown previously that the efficiency of photodynamic therapy (PDT) both in vivo and in vitro is dependent on fluence rate. In this study, different in vitro experiments showed that tetrasulfonated aluminum phthalocyanine (AlPcS4) is m

The fluorescent dye Merocyanine 540 (MC540) is often used as a probe to monitor the molecular packing of phospholipids in the outer leaflet of biomembranes. In a previous study we showed that the increased staining of erythrocytes with a perturbed me

Phthalocyanines are useful sensitizers for the photodynamic sterilization of red blood cell concentrates. The mechanism of photoinactivation of lipid-enveloped viruses is not completely understood. Vesicular stomatitis virus (VSV) was used as a model

We studied the effect of exogenous nitric oxide (NO) on migration of rabbit peritoneal neutrophils. Exogenous NO enhanced random migration of neutrophils in a concentration-dependent way. An optimally stimulatory effect was observed with 0.5 μM NO,

The interaction of the red cell membrane with merocyanine 540 or protoporphyrin led to four phenomena, most probably interrelated. (i) The morphology changed from the normal discoid to an echinocytic form. This morphological change persisted when fol

— Loss of clonogenicity of Chinese hamster ovary (CHO) cells, murine L929 fibroblasts and human bladder carcinoma T24 cells caused by photodynamic treatment (PDT) with hematoporphyrin derivative (HPD) is synergistically enhanced by subsequent incub

In the presence of albumin Merocyanine 540 (MC540) exhibits a very limited binding to the outer surface of the membrane of normal erythrocytes, whereas pronounced binding is observed to leukemia cells. To find out whether this difference is due to di
