Possible protective effect of natural flavanone naringenin-reduced graphene oxide nanosheets on nonalcoholic fatty liver disease.

Utilizing naringenin as a safe, natural compound for reducing graphene oxide and to determine whether Nar-RGO more effectively mitigates the harmful effects of HFFD-induced NAFLD compared to crude naringenin. Using a straightforward experimental setup, we utilize the bioactive flavonoid naringenin (NAR) as the reducing agent to synthesize naringenin-reduced graphene oxide nanosheets (Nar-RGO). Naringenin loading on graphene oxide was validated using electroscopic methods (SEM and TEM) and zeta potential measurements.

HCl-induced acute lung injury: a study of the curative role of mesenchymal stem/stromal cells and cobalt protoporphyrin.

Background: This study was designed to investigate bone marrow mesenchymal stem/stromal cells (BM-MSCs) and cobalt protoporphyrin (CoPP) curable effects on HCl-induced acute lung injury (ALI) and its underlying mechanisms hoping this might aid to offer a therapeutic opportunity for ALI.

Results: Forty male Sprague Dawley rats were randomly allocated into four groups; normal (normal rats), ALI (rats injected with 2 ml hydrochloric acid (HCl)/kg via trachea), ALI + BM-MSCs (ALI rats intravenously injected twice with 1 × 10 BM-MSCs/rat/week), and ALI + CoPP (ALI rats intraperitoneally injected twice with CoPP (0.5 mg/100 g/week)).

Antitumor activity of sitagliptin and vitamin B12 on Ehrlich ascites carcinoma solid tumor in mice.

This study was carried out to investigate the potential effects of vitamin B12 and sitagliptin, and their possible synergistic effect with doxorubicin (DOX) on the Ehrlich solid tumor model. B12, sitagliptin, and their combination with DOX were administered to tumor-bearing mice for 21 days. Treatment with B12, sitagliptin, as well as their combinations with DOX caused a significant inhibition of tumor growth and increased the survival time.

EGF Conjugation Improves Safety and Uptake Efficacy of Titanium Dioxide Nanoparticles.

Titanium dioxide nanoparticles (TiO NPs) have a strong potential for cancer therapeutic and bioimaging applications such as photodynamic therapy (PDT) and photodynamic diagnosis (PDD). Our previous results have shown that TiO NPs have a low cellular uptake and can induce cell proliferation. This suggests that TiO NPs could increase the risk of tumor overgrowth while being used for PDD and PDT.

Protective effect of fenofibrate against high-fat-high-fructose diet induced non-obese NAFLD in rats.

The present study evaluated the protective effects of fenofibrate on liver function, oxidant-antioxidant balance, and insulin resistance (IR) in rats fed high-fat-high-fructose diet (HFFD). Twenty-four male Sprague-Dawley rats (110-130 gm) were allocated into four equal groups (n = 6). Rats in group I were fed a normal diet for 4 weeks.

The Effects of TiO Nanoparticles on Cisplatin Cytotoxicity in Cancer Cell Lines.

There have been many studies on improving the efficacy of cisplatin and on identifying safe compounds that can overcome multi-drug resistance (MDR) acquired by cancer cells. Our previous research showed that polyethylene glycol-modified titanium dioxide nanoparticles (TiO PEG NPs) affect cell membrane receptors, resulting in their aggregation, altered localization and downregulation. TiO PEG NPs may affect P-glycoprotein (P-gp), a membrane efflux channel involved in MDR.

Ameliorative effects of l-carnitine on rats raised on a diet supplemented with lead acetate.

Lead intoxication has been a major health hazard in humans. It affects people at all ages. Its toxicity is associated with various organs of the body and affects different metabolic pathways.

The E3 ubiquitin ligase WWP1 regulates ΔNp63-dependent transcription through Lys63 linkages.

The transcription factor p63, a member of the p53 family, plays a crucial role in epithelial development and tumorigenesis through the regulation of epithelial progenitor cell proliferation, differentiation and apoptosis. Similarly to p53, p63 activity is regulated by post-translational modifications, including ubiquitylation. Here, we report that the WWP1 E3 ubiquitin ligase binds specifically to ΔNp63 isoform but it does not trigger ΔNp63 proteasome-dependent degradation.

The sequence and phylogenesis of the ?-globin genes of Barbary sheep (Ammotragus lervia), goat (Capra hircus), European mouflon (Ovis aries musimon) and Cyprus mouflon (Ovis aries ophion).

In order to investigate the polymorphism of ?-globin chain of hemoglobin amongst caprines, the linked (I)? and (II)? globin genes of Barbary sheep (Ammotragus lervia), goat (Capra hircus), European mouflon (Ovis aries musimon), and Cyprus mouflon (Ovis aries ophion) were completely sequenced, including the 5? and 3? untranslated regions. European and Cyprus mouflons, which do not show polymorphic ? globin chains, had almost identical ? globin genes, whereas Barbary sheep exhibit two different chains encoded by two nonallelic genes. Four different ? genes were observed and sequenced in goat, validating previous observations of the existence of allelic and nonallelic polymorphism.

Barbary sheep (Ammotragus lervia): the structure of the adult beta-globin gene and the functional properties of its hemoglobin.

The adult beta-globin gene of Ammotragus lervia (Barbary sheep or aoudad) has been sequenced completely, including 185 base pairs of 5' flanking region and 168 base pairs 3' to the stop codon, and compared with that of other caprines such as goat (Capra hircus), wild Corsico-Sardinian (Ovis aries musimon) and Cypriot (O. a. ophion) mouflons, and domestic sheep (Ovis aries).
