AB  - Nowadays bacterial resistance to known antibiotics is a serious health problem. In order to achieve more efficient treatment, lately there is an effort to find new substances, such as certain biomaterials, that are non-toxic to humans with antibiotic potential. Lignins and lignin-derived compounds have been proposed to be good candidates for use in medicine and health maintenance. In this study, the antibacterial activity of the lignin model polymer dehydrogenate polymer (DHP) in alginate hydrogel (Alg) was studied. The obtained results show that DHP-Alg has strong antimicrobial activity against several bacterial strains and biofilms and does not have a toxic effect on human epithelial cells. These results strongly suggest its application as a wound healing agent or as an adjunct substance for wound treatments.

AB  - Soy isoflavones represent hopeful unconventional remedies in the therapy of prostate cancer. The aim of our study was to determine the effects of genistein and daidzein on the parameters that reflect metastatic potential, membrane fluidity, invasiveness and dynamic phenotype in Matrigel of LNCaP and PC-3 prostate cancer cells. Cell viability tests, using a wide range of concentrations of soy isoflavones (6-75 mu g/ml for 72 h), were conducted to determine their IC50 concentrations. Electron paramagnetic resonance investigations of prostate cancer cell membrane fluidity were performed at IC50 concentrations of genistein and daidzein (12.5 and 25 mu g/ml, respectively, for 10 min). Genistein provoked significant increases in the membrane order parameter (which is reciprocally proportional to membrane fluidity) of 0.722 +/- A 0.006 (LNCaP), 0.753 +/- A 0.010 (LNCaP + genistein), 0.723 +/- A 0.007 (PC-3) and 0.741 +/- A 0.004 (PC-3 + genistein); however, no such effects were observed for daidzein. While both genistein and daidzein reduced the proliferation of prostate cancer cells at their respective IC50 concentrations, during the 72 h of incubation only genistein provoked effects on the dynamic phenotype and decreased invasiveness. The effect was more evident in PC-3 cells compared to LNCaP cells. Our results imply that (1) invasive activity is at least partially dependent on membrane fluidity, (2) genistein may exert its antimetastatic effects by changing the mechanical properties of prostate cancer cells and (3) daidzein should be applied at higher concentrations than genistein in order to achieve pharmacological effects.

AB  - Advanced age is often accompanied by glucocorticoid excess which contributes to the pathogenesis of the metabolic syndrome associated with some hemodynamic disorders. Impaired central regulation of stress hormones secretion and increased glucocorticoids/adrenal androgens ratio trigger hyperglycemia, elevated blood lipids and visceral fat accumulation, associated with hypertension and increased blood viscosity, all of which represent cardiovascular morbidity factors in this age. Finding the adequate therapeutic solutions is set as an imperative in the treatment of listed symptoms. Biologically active soy isoflavones, exhibiting estrogen- and membrane-receptor agonistic/antagonistic activity, and antioxidative and tyrosine kinase/steroidogenic enzyme inhibiting effects, appear as alternative therapeutics for various ageing-related diseases. It has been shown that soy isoflavones reduce some of the listed risk factors, while affecting the hemodynamic group of cardiovascular parameters directly, as well as indirectly via endocrine perturbations. Soy isoflavones may reverse the glucocorticoids/adrenal androgens ratio, lower serum cholesterol, slow the development of atherosclerotic plaque formation, inhibit platelet aggregation, increase cardiac contractility, but they may have diverse effects on blood viscosity and may increase triglyceride levels. Herein, we present the projection of soy isoflavones-based therapy of glucocorticoid excess and disturbed hemodynamics in advanced age, concluding that although promising, it requires the impartial approach and certain precautions.

After treatment with Vitex agnus-castus essential oil the erythrocytes had a significant (p=0.029) and reversible increase in membrane fluidity in the deeper hydrophobic membrane regions, with no change (p>0.05) in fluidity near the membrane's hydrophilic surface.

AB  - A decrease of erythrocyte membrane fluidity can contribute to the pathophysiology of hypertension. Soy products, which are used as alternative therapeutics in some cardiovascular conditions, contain various isoflavones (genistein, daidzein, and their glucosides, genistin and daidzin), which can incorporate cellular membrane and change its fluidity. The aim of this study was to examine the effects of soy extract (which generally corresponds to the soy products of isoflavone composition) on erythrocyte membrane fluidity at graded depths. We used electron paramagnetic resonance spectroscopy and fatty acid spin probes (5-DS and 12-DS), the spectra of which are dependent on membrane fluidity. After being treated with soy extract, erythrocytes showed a significant (P = 0.016) decrease of membrane fluidity near the hydrophilic surface, while there were no significant changes of fluidity in deeper hydrophobic membrane regions. These results suggest that soy products containing high levels of genistein and isoflavone glucosides may not be suitable for use in hypertension because they decrease erythrocyte membrane fluidity.

AB  - The maintenance of erythrocyte membrane fluidity at the physiological level is an important factor affecting the ability of erythrocytes to pass through blood vessels of small luminal diameter. Genistein and daidzein, which are used as alternative therapeutics in cardiovascular conditions, can be incorporated into the cell membrane and change its fluidity. The aim of this study was to examine the effects of genistein and daidzein on erythrocyte membrane fluidity at graded depths. We used electron paramagnetic resonance (EPR) spectroscopy and fatty acid spin probes (5-DS and 12-DS) where EPR spectra were dependent on fluidity. The results showed that genistein significantly (p  lt  0.05) decreased erythrocyte membrane fluidity near the hydrophilic surface, while daidzein significantly (p  lt  0.05) increased the same parameter in deeper regions of the membrane. These data suggest that the deep fluidizing effects of daidzein on erythrocyte membranes make it a better therapeutic choice than genistein in some cardiovascular conditions.
