Microbiological corossion of metallic products as a result of biofilm
PublicationWarunkiem do pojawienia się korozji mikrobiologicznej jest utworzenie na powierzchni metalu biofilmu. Zawiera on biologicznie czynne mikroorganizmy wraz z produktami ich przemian metabolicznych. Biofilm ogranicza dyfuzję produktów metabolizmu wytwarzanych przez poszczególne komórki mikrokolonii. Powoduje to, że produkty uboczne tych przemian gromadzą się w bezpośrednim sąsiedztwie metalu. Gdy powierzchnia metalu nie jest odporna...

Bismuth-Doped Nano Zerovalent Iron: A Novel Catalyst for Chloramphenicol Degradation and Hydrogen Production
PublicationIn this study, we showed that doping bismuth (Bi) at the surface of Fe0 (Bi/Fe0, bimetallic iron system)—synthesized by a simple borohydride reduction method—can considerably accelerate the reductive degradation of chloramphenicol (CHP). At a reaction time of 12 min, 62, 68, 74, 95, and 82% degradation of CHP was achieved with Fe0, Bi/Fe0-1 [1% (w/w) of Bi], Bi/Fe0-3 [3% (w/w) of Bi], Bi/Fe0-5 [5% (w/w) of Bi], and Bi/Fe0-8 [8%...

Novel therapeutic compound acridine–retrotuftsin action on biological forms of melanoma and neuroblastoma
PublicationPURPOSE: As a continuation of our search for anticancer agents, we have synthesized a new acridine-retrotuftsin analog HClx9-[Arg(NO2)-Pro-Lys-Thr-OCH3]-1-nitroacridine (named ART) and have evaluated its activity against melanoma and neuroblastoma lines. Both tumors develop from cells (melanocytes, neurons) of neuroectodermal origin, and both are tumors with high heterogeneity and unsatisfactory susceptibility to chemotherapies....

Cardinal regenerative features of the MRL mouse
PublicationIn this review, we discuss recent studies relating to major features of adult MRL mouse biology that contribute to the regenerative responses seen. These include an increased inflammatory cell profile, a unique glycolytic metabolic state typically found during embryogenesis, and a cell cycle phenotype of DNA damage and G2/M arrest. These traits have been found in other mammalian and non-mammalian regenerative systems. How these...

Rola polimorfizmu i zróżnicowanej ekspresji genów cytochromu P450 w metabolizmie ksenobiotyków.
PublicationZdolność do metabolizmu ksenobiotyków przez cytochromy P450 (CYP) określona jest przez polimorfizm i poziom ekspresji genów tych białek. Najwięcej, 40 odmian polimorficznych o zróżnicowanej aktywności enzymatycznej, poznano dla CYP2D6, natomiast tylko dwie w przypadku CYP2C9, których obecność powoduje zahamowanie metabolizmu wielu leków. Z kolei polimorfizm genu CYP3A4 nie miał istotnego wpływu na aktywność metaboliczną jego produktu...

Structure modification of acridine antitumor agents results in changes of enzymatic activity and gene expression of CYP3A4 isoenzyme in HepG2 cells.
PublicationEkspresja izoenzymu CYP3A4, który zaangażowany jest w metabolizm ok. 60% leków stosowanych klinicznie, może być modulowana przez takie czynniki jak: polimorfizm, czynniki transkrypcyjne oraz obecność ksenobiotyków. Przykładem induktorów genów kodujących izoenzym CYP3A4 jest fenobarbital i rifampicyna, których obecność w organizmie przyspiesza metabolizm innych leków stosowanych jednocześnie, które są substratami dla CYP3A4. Dlatego...

Post-Effort Changes in Autophagy- and Inflammation-Related Gene Expression in White Blood Cells of Healthy Young Men
PublicationAcute, strenuous physical exertion requiring high levels of energy production induces the production of reactive oxygen species and metabolic disturbances that can damage the mitochondria. Thus, selective autophagic elimination of defective mitochondria may improve resistance to oxidative stress and potentially to inflammation. The main goal of this study was to evaluate the impacts of intense effort on changes in the expression...

Biosynthetic and synthetic access to amino sugars.
PublicationAmino sugars are important constituents of a number of biomacromolecules and products of mi crobial secondary metabolism, including antibiotics. For most of them, the amino group is located at the positions C1, C2 or C3 of the hexose or pentose ring. In biological systems, amino sugars are formed due to the catalytic activity of specific aminotransferases or amidotransferases by introducing an amino functionality derived from L-glutamate...

Pendant Proton-Relays Systematically Tune the Rate and Selectivity of Electrocatalytic Ammonia Generation in a Fe-Porphyrin Based Metal-Organic Framework
PublicationElectrocatalytic nitrite reduction (eNO2RR) is a promising alternative route to produce ammonia (NH3). Until now, several molecular catalysts have shown capability to homogeneously reduce nitrite to NH3, while taking advantage of added secondary-sphere functionalities to direct catalytic performance. Yet, realizing such control over heterogeneous electrocatalytic surfaces remains a challenge. Herein, we demonstrate that heterogenization...

State of the art in sample preparation for human breast milk metabolomics—merits and limitations
PublicationHuman breast milk (HBM) contains metabolites that are diverse in chemical structure and concentration. These metabolites range from high-abundance to low-abundance compounds and from polar to nonpolar. This complex nature of HBM makes HBM samples difficult to analyze, especially in global metabolomic studies for the determination and characterization of complete sets of metabolites. In this review, the state of the art in sample...

Endothelial Dysfunction Driven by Hypoxia—The Influence of Oxygen Deficiency on NO Bioavailability
PublicationCardiovascular diseases (CVDs) are the leading cause of death worldwide. The initial stage of CVDs is characterized by endothelial dysfunction, defined as the limited bioavailability of nitric oxide (NO). Thus, any factors that interfere with the synthesis or metabolism of NO in endothelial cells are involved in CVD pathogenesis. It is well established that hypoxia is both the triggering factor as well as the accompanying factor...
