AB  - Fullerenol C60(OH)24 with its spherical shape, symmetrical structure, 1 nm size and the ability to form polyionic nanoparticles in water solution, was used to synthesise a novel nanocomposite made of fullerenol nanoparticles (FNP) and iron ions (Fe2+). The FNP/Fe2+ nanocomposite was characterised by DLS and TEM-EDS analyses which have shown that the size distribution of FNP/Fe2+ stayed in the same scope as the size distribution of FNP, ranging from 11 to 60 nm. However, Fe2+ did affect the change of FNP’s zeta potential (− 49.2 mV), shifting it to more positive values (− 30.8 mV). In this study, it was assumed that FNP/Fe2+ could reduce the toxic effects of doxorubicin (Dox). Male Wistar rats were treated i.p. with FNP/Fe2+ nanocomposite 1 h prior to Dox treatment. At the subcellular level, the ultrastructural analysis revealed minor alterations sporadically displayed within the heart and liver tissues. Moreover, at the molecular level, the gene expressions analysis of mRNAs for catalase (heart and liver) and MnSOD (only liver) were significantly downregulated, indicating reduction in oxidative stress. Overall, the pretreatment with FNP/Fe2+ nanocomposite, followed by Dox application, significantly diminished harmful effects of the applied drug on the heart and liver, suggesting the potential protective effect of the nanocomposite on the healthy tissues. © 2019, Springer Nature B.V.

AB  - Gestational diabetes mellitus (GDM) and pregnancy-induced hypertension (PIH) can jeopardize mother and/or fetus. Vascular ATP-sensitive potassium (KATP) channels most likely participate in the processes of diabetes and hypertension. The aim of this research was to examine whether GDM and PIH cause changes in the expression and function of KATP channels in vascular smooth muscle of human umbilical vein (HUV). Western blot and immunohistochemistry detected significantly decreased expression of Kir6.1 subunit of KATP channels in GDM and PIH, while the expression of SUR2B was unchanged. In GDM, a K+ channel opener, pinacidil caused reduced relaxation of the endothelium-denuded HUVs compared to normal pregnancy. However, its effects in HUVs from PIH subjects were similar to normal pregnancy. In all groups KATP channel blocker glibenclamide antagonized the relaxation of HUV induced by pinacidil without change in the maximal relaxations indicating additional KATP channel-independent mechanisms of pinacidil action. Iberiotoxin, a selective antagonist of large-conductance calcium-activated potassium channels, inhibited the relaxant effect of pinacidil in PIH, but not in normal pregnancy and GDM. Experiments performed in K+-rich solution confirmed the existence of K+-independent effects of pinacidil, which also appear to be impaired in GDM and PIH. Thus, the expression of KATP channels is decreased in GDM and PIH. In GDM, vasorelaxant response of HUV to pinacidil is reduced, while in PIH it remains unchanged. It is very likely that KATP channels modulation and more detailed insight in KATP channel-independent actions of pinacidil may be precious in the therapy of pathological pregnancies. © 2019 Elsevier Inc.

AB  - BACKGROUND: Oestradiol is an important regulatory factor with several positive effects on the cardiovascular (CV) system. We evaluated the molecular mechanism of the in vivo effects of oestradiol on the regulation of cardiac inducible nitric oxide (NO) synthase (iNOS) expression and activity. METHODS: Male Wistar rats were treated with oestradiol (40 mg/kg, intraperitoneally) and after 24 h the animals were sacrificed. The concentrations of NO and L-Arginine (L-Arg) were determined spectrophotometrically. For protein expressions of iNOS, p65 subunit of nuclear factor-κB (NFκB-p65), Ras homolog gene family-member A (RhoA), angiotensin II receptor type 1 (AT1R), insulin receptor substrate 1 (IRS-1), p85, p110 and protein kinase B (Akt), Western blot method was used. Coimmunoprecipitation was used for measuring the association of IRS-1 with the p85 subunit of phosphatidylinositol- 3-kinase (PI3K). The expression of iNOS messenger ribonucleic acid (mRNA) was measured with the quantitative real-time polymerase chain reaction (qRT-PCR). Immunohistochemical analysis of the tissue was used to detect localization and expression of iNOS in heart tissue. RESULTS: Oestradiol treatment reduced L-Arg concentration (p<0.01), iNOS mRNA (p<0.01) and protein (p<0.001) expression, level of RhoA (p<0.05) and AT1R (p<0.001) protein. In contrast, plasma NO (p<0.05), Akt phosphorylation at Thr308 (p<0.05) and protein level of p85 (p<0.001) increased after oestradiol treatment. CONCLUSION: Our results suggest that oestradiol in vivo regulates cardiac iNOS expression via the PI3K/Akt signaling pathway, through attenuation of RhoA and AT1R.

AB  - The aim of this study was to assess the effects of l-cysteine (Cys) (7 mg/kg) and N-acetyl-l-cysteine (NAC) (50 mg/kg) in the rat liver caused by subchronic i.p. application of methionine (Met) (0.8 mmol/kg) during 21 days. Malondialdehyde (MDA) concentration, glutathione content (GSH), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and acetylcholinesterase (AchE) activities were determined in the liver tissue and activities of liver enzymes (AST, ALT, ALP, and GGT) and concentrations of total proteins and albumin were determinated in plasma/serum. Catalase, superoxide dismutase, and acetylcholinesterase activities were increased by Cys and NAC. Met caused periportal mononuclear infiltration and rare focal necrosis of hepatocytes. In Cys- and NAC-supplemented groups, intracellular edema and microvesicular fatty changes without necrosis were noticed. We observed decrease of AST, ALT, and ALP activity in the methionine-treated group. Our results indicate that Cys and NAC application can increase activity of antioxidative enzymes and prevent intensive histological changes in liver in condition of subchronic methionine exposure.

AB  - In our recent studies we have designed fullerenol/doxorubicin nanocomposite (FNP/DOX) as the new drug nanocarrier. This research has demonstrated that this novel nanocomposite has had better implications on the liver tissue in vivo (Wistar rats treated intraperitoneally), than treatment based only on DOX. FNP/DOX has been characterised by DLS, TEM and AFM measurements which have shown that DOX loaded onto FNP did not influence fullerenol nanoparticle's size. FNP/DOX affected oxidative status in blood causing a significant decrease of catalase and SOD activity in comparison to DOX, implicating the reduction in oxidative stress. qRT-PCR results on the mRNA level of antioxidative enzymes (catalase and MnSOD) revealed that the effect of oxidative stress is significantly reduced by the treatment with FNP/DOX (p <.05). The ultrastructural analysis of the liver tissue has revealed that FNP/DOX nanocomposite generated considerably less damage in the liver tissue, than DOX applied at the same dose. Hence, our results have indicated that FNP, within FNP/DOX nanocomposite, exhibits protective effects to the liver tissue of the healthy rats.

AB  - Mucograft is collagen matrix was designed for use in open healing situations due to its compact outer layer. The technique presented in this article is an attempt to avail this attribute for covering open oral wound in guided bone regeneration (GBR) procedure. The essential idea of this technique is to avoid scoring of periosteum, submucosa and muscle layer for buccal flap advancement. Therefore, we used mucograft to cover bone substitute and barrier membrane in GBR surgical procedure. Thus, we avoided periostal-releasing incisions (PRI) and gained reposition of the flap to original level without impairing the attached keratinized gingiva. Buccal flap advancement in situations of shallow vestibulum, shortly attached gingiva and strong muscle pull may reduce or eliminate attached gingiva with an adverse effect on extended survival of placed implants. This technique promises to be beneficial for the preservation of the soft tissue around dental implants after GBR procedure.

AB  - Fullerenol (C-60(OH)(24)) is present in aqueous solutions in the form of polyanion nanoparticles with particles size distribution within the range from 15 to 42 nm. In this research it is assumed that these features could enable fullerenol nanoparticles (FNPs) to bind positively charged molecules like doxorubicin (DOX) and serve as drug carriers. Considering this, fullerenol/doxorubicin nanocomposite (FNP/DOX) is formed and characterized by ultra-performance liquid chromatography tandem mass spectrometry, dynamic light scattering, atomic force microscopy and transmission electron microscopy. Measurements have shown that DOX did not significantly affect particle size (23 nm). It is also assumed that FNP/DOX could reduce the acute cardiotoxic effects of DOX in vivo (Wistar rats treated i.p.). In this study, quantitative real time polymerase chain reaction results have shown that treatment with DOX alone caused significant increase in mRNA levels of catalase (p LT 0.05) enzyme indicating the presence of oxidative stress. This effect is significantly reduced by the treatment with FNP/DOX (p LT 0.05). Furthermore, mRNA levels of antiapoptotic enzyme (Bcl-2) are significantly increased (p LT 0.05) in all treated groups, particularly where FNP/DOX was applied, suggesting cell resistance to apoptosis. Moreover, ultrastructural analysis has shown the absence of myelin figures within the mitochondria in the heart tissue with FNP/DOX treatment, indicating reduction of oxidative stress. Hence, our results have implied that FNP/DOX is generally less harmful to the heart compared to DOX.

AB  - We studied the in vivo effects of estradiol on size and biochemical parameters of cardiomyocytes in pathophysiological conditions such as obesity and insulin resistance. Male Wistar rats were normally fed (controls, n = 7) or fed with high-fat diet (obese, n = 14). Half of the obese rats (obese + estradiol, n = 7) were treated with a single dose of estradiol (40 g/kg, intraperitoneally) and 24 hours after treatment all the rats were killed. Estradiol in vivo in obese rats resulted in a significant increase in protein kinase B (Akt) activation (P LT .05) and decrease in heart mass (P LT .05), ratio of the heart mass/body mass (P LT .05), transverse diameters of cardiomyocytes (P LT .001), concentration of serum high-sensitivity C-reactive protein (P LT .001), and total cholesterol (P LT .01) compared with obese nontreated rats. Our results suggest that estradiol in obese/IR rats affects the size of cardiomyocytes and its actions lead in vivo to a reduction in obesity-induced cardiac hypertrophy, via Akt.

AB  - The aim of this study was to investigate in vivo effects of estradiol on Na+/K+-ATPase activity/expression in high fat (HF) diet fed rats. Adult male Wistar rats were fed normally (Control, n = 7) or with a HF diet (Obese, n = 14) for 10 weeks. After 10 weeks, half of the obese rats were treated with estradiol (Obese + Estradiol, n = 7, 40 mu g/kg, i.p.) as a bolus injection and 24 h after treatment all the rats were sacrificed. Estradiol in vivo in obese rats in comparison with obese non-treated rats led to a statistically significant increase in concentration of serum Na+ (p LT 0.05), Na+/K+-ATPase activity (p LT 0.01), expression of alpha 1 (p LT 0.01) and alpha 2 (p LT 0.05) subunit of Na+/K+-ATPase, both PI3K subunits p85 (p LT 0.01), p110 (p LT 0.05), and association of IRS-1 with p85 (p LT 0.05), while significantly decrease expression of AT1 (p LT 0.05) and Rho A (p LT 0.01) proteins. Our results suggest that estradiol in vivo in pathophysiological conditions, such as obesity accompanied with insulin resistance stimulates activity and expression of Na+/K+-ATPase by a mechanism that involves the participation of IRS-1/PI3K/Akt signaling. In addition, the decreasing level of AT1 and Rho A proteins estradiol probably attenuates the detrimental effect of obesity to decreased IRS-1/P13K association and consequently reduce Na+/K+-ATPase activity/expression.

AB  - In this study the in vivo effects of estradiol in regulating Na+/K+-ATPase function in rat heart was studied. Adult male Wistar rats were treated with estradiol (40 mu g/kg, i.p.) and after 24 h the animals were sacrificed and the heart excised. Following estradiol administration, cardiac Na+/K(+)ATPase activity, expression of the alpha l subunit, and phosphorylation of the al subunit were significantly increased. These animals also had significantly decreased levels of digoxin-like immunoreactive factor(s). Na+ levels were also significantly reduced but to a level that was still within the normal physiological range, highlighting the ability of the Na+/K+-ATPase to balance the ionic composition following treatment with estradiol. Estradiol treated rats also showed increased phosphorylation of protein kinase B (Akt), and extracellular-signal-regulated kinase 1/2 (ERK1/2). We therefore suggest a role for Akt and/or ERK1/2 in estradiol-mediated regulation of cardiac Na+/K+-ATPase expression and activity in rat heart. (C) 2014 Elsevier Ireland Ltd. All rights reserved.

AB  - In humans uric acid (UA) is the end product of degradation of purines. The handling of UA by the renal system is a complex process which is not fully understood. To date, several urate transporters in the renal proximal tubule have been identified. Among them, urate transporter 1 (URAT1) and a glucose transporter 9 (GLUT9) are considered of greater importance, as potential targets for treatment of hyperuricemia and the potential associated cardio-metabolic risk. Therefore, the recognition of the metabolic pathway of UA and elucidation of occurrence of hyperuricemia may provide important insights about the relationship between UA, pre-hypertension (preHT) and the metabolic syndrome (MetS). We also review the available clinical studies in this field, including experimental studies dealing with the mechanisms of UA transport via different transporters, as well as current treatment options for hyperuricemia in patients with MetS, preHT or cardiovascular risk factors.

abstract = "In humans uric acid (UA) is the end product of degradation of purines. The handling of UA by the renal system is a complex process which is not fully understood. To date, several urate transporters in the renal proximal tubule have been identified. Among them, urate transporter 1 (URAT1) and a glucose transporter 9 (GLUT9) are considered of greater importance, as potential targets for treatment of hyperuricemia and the potential associated cardio-metabolic risk. Therefore, the recognition of the metabolic pathway of UA and elucidation of occurrence of hyperuricemia may provide important insights about the relationship between UA, pre-hypertension (preHT) and the metabolic syndrome (MetS). We also review the available clinical studies in this field, including experimental studies dealing with the mechanisms of UA transport via different transporters, as well as current treatment options for hyperuricemia in patients with MetS, preHT or cardiovascular risk factors.",

AB  - Cardioprotective effects of fullerenol C-60(OH)(24) nanoparticles (FNP) were investigated in pigs after a single treatment with doxorubicin (DOX). Semithin and ultrathin sections of myocardial tissue routinely prepared for transmission electron microscopy were analyzed. Extensive intracellular damage was confirmed in cardiomyocytes of DOX-treated animals. By means of ultrastructural analysis, a certain degree of parenchymal degeneration was confirmed even in animals treated with FNP alone, including both the oral and the intraperitoneal application of the substance. The cardioprotective effects of FNP in animals previously treated with DOX were recognized to a certain extent, but were not fully confirmed at the ultrastructural level. Nevertheless, the myocardial morphology of DOX-treated animals improved after the admission of FNP. Irregular orientation of myofibrils, myofibrillar disruption, intracellular edema, and vacuolization were reduced, but not completely eliminated. Reduction of these cellular alterations was achieved if FNP was applied orally 6 h prior to DOX treatment in a dose of 18 mg/kg. However, numerous defects, including the inner mitochondrial membrane and the plasma membrane disruption of certain cells persisted. In FNP/DOX-treated animals, the presence of multinuclear cells with mitosis-like figures resembling metaphase or anaphase were observed, indicating that DOX and FNP could have a complex influence on the cell cycle of cardiomyocytes. Based on this experiment, further careful increase in dosage may be advised to enhance FNP-induced cardioprotection. These investigations should, however, always be combined with ultrastructural analysis. The FNP/DOX interaction is an excellent model for the investigation of cardiomyocyte cell death and cell cycle mechanisms.
