Cancer continues to be a major cause of mortality globally. Zebrafish present suitable models for studying the mechanisms of genotoxic carcinogens. The aim of this study was to investigate the interaction between oxidant-antioxidant status, apoptosis and immunity in zebrafish that were exposed to three different genotoxic carcinogens methylnitrosourea, dimethylbenzanthracene, benzoapyrene and methylnitrosourea + dimethylbenzanthracene starting from early embryogenesis for 30 days. Lipid peroxidation, nitric oxide levels, superoxide dismutase and glutathione-S-transferase activities and mRNA levels of apoptosis genes p53, bax, casp3a, casp2 and immunity genes fas, tnfα and ifnγ1 were evaluated. The disruption of the oxidant-antioxidant balance accompanied by altered expressions of apoptotic and immunity related genes were observed in different levels according to the carcinogen applied. Noteworthy, ifnγ expressions decreased in all carcinogen-exposed groups. Our results will provide basic data for further carcinogenesis research in zebrafish models.Sepsis is one of the most common causes of death among hospitalized patients. Activity of xanthine oxidase (XO), a reactive oxygen species-producing enzyme, is known to be elevated in septic patients. Our aim was to investigate the possible protective role of XO inhibitor, febuxostat (FEB), in a rat model of sepsis-induced liver and kidney injures. Adult male albino rats were divided into four groups (n = 12 each) sham control, sham + FEB, cecal ligation and puncture (CLP), and CLP + FEB groups. FEB (10 mg/kg per os (p.o.)) was given once daily for 2 days and 30 min prior to laparotomy with CLP. this website CLP was associated with a high mortality rate accompanied by significant liver and kidney injuries indicated by elevated serum alanine aminotransferase, aspartate aminotransferase, urea, and creatinine levels and confirmed by histopathological tissue injury. Moreover, there was an increase in neutrophil gelatinase-associated lipocalin, uric acid, malondialdehyde, and nitric oxide levels and with decreased superoxide dismutase activity and total antioxidant capacity. In addition, CLP caused increased expression of the inflammatory markers tumor necrosis factor alpha, interleukin 1beta protein levels, and nuclear factor kappa B immunoexpression. Finally, CLP operated rats exhibited an upregulation in the apoptotic mediators, caspase 3, and P-C-Jun N-terminal kinases (JNK) proteins. FEB treatment of CLP rats caused a significant improvement and normalization in all measured parameters. Moreover, FEB amerliorates degenerative histopathological changes and improves the overall survival rate. In conclusion, FEB exhibited a protective effect in sepsis-induced liver and kidney injuries most probably through its anti-inflammatory, antioxidant, and antiapoptotic properties and attenuating JNK signaling pathway secondary to its XO enzyme inhibitory activity.Cytochrome P450 4B1 (CYP4B1) plays crucial roles in biotransforming of xenobiotics. Its predominant extrahepatic expression has been associated with certain tissue-specific toxicities. However, the expressions of CYP4B1 in various cancers and hence their potential roles in cancer development were inclusive. In this work, existing knowledge on expression and regulation of CYP4B1 gene and protein, catalysis of CYP4B1, association of CYP4B1 with cancers, contradicting findings about human CYP4B1 activities as well as the employing CYP4B1 in suicide gene approach for cancer treatment were reviewed. To date, it appears that there is a wide spectrum of tissue distribution of CYP4B1 with lungs as the predominant sites. Several nuclear receptors are possibly responsible for regulating its gene expression. The involvement of CYP4B1 in cancer was considered via activation of procarcinogens and neovascularization. However, human CYP4B1 was found to be inactive due to a substitution of proline with serine at position 427. Suicide gene approach combining reengineered CYP4B1 and prodrug 4-ipomeanol (4-IPO) has shown a promising potential for targeted cancer therapy. Further studies should focus on the verification of human CYP4B1 catalytic activities. More compounds with similar structure as 4-IPO should be tested to identify more alternative agents for the suicide gene approach in cancer treatment.Supporting the development of young family planning professionals is key to fostering communities of practitioners that can help countries achieve family planning goals. The Family Planning Voices (FP Voices) storytelling initiative, created by The Knowledge for Health Project and Family Planning 2020, documents stories from people around the world who are passionate about family planning. This qualitative evaluation used in-depth interviews (n = 11) with young professionals (ages 18-30) to uncover the effects of sharing their story with FP Voices. Participants came from 10 countries in one of three regions, Latin America (n = 2), South Asia (n = 2), and Africa (n = 7). Findings highlight that sharing one's story with FP Voices served as a professional development opportunity and instilled confidence and pride among young professionals. Additionally, participants linked access to a professional headshot and the experience of participating in an interview to their professional development. Participants often discussed the recognition they gained from sharing their story and the resulting increase in professional connections and opportunities. Participants hoped that their stories would inspire and encourage others and support recognition of the value of young professionals to the larger family planning field. In sum, storytelling initiatives like FP Voices can motivate and create community and opportunity among young professionals.With an increasing interest in exploring the biocatalyst potential for the production of natural products (NP), research in NP biotechnology now follows. Xanthones constitute an important class of phytochemicals exhibiting a myriad of bioactivities and potential for interacting with multimolecular targets, and xanthones are considered to be privileged phytochemical scaffolds in medicinal chemistry. Recent advances in xanthones biosynthetic pathways are outlined and their metabolic engineering. This review summarizes the state-of-the-art processes for the biotechnological production of xanthones, its limitations, and potential improvements. The in vitro tissue culturing methods employed for the production of xanthones from different species of plant are reviewed addressing differences in xanthone classes. This review sheds the light of computational approaches, viz., response surface methodology (RSM) and artificial neural networks (ANN), for optimizing the culture performance and improving xanthones production.
