Open Journal of Medical Microbiology 2024年第2期14卷 120-130页

Background: In recent times, there has been an increase in the number of Lassa fever cases resulting from the several episodes of Lassa fever epidemics ravaging Nigeria and other West African countries. The presence of Lassa virus in rodents other than the major reservoir (Mastomys natalensis) has been a public health concern as to the actual burden of the disease. It is therefore of a public health necessity to explore the LASV RNA habouring potential of several species of rodents in endemic as well as non-endemic areas for proper prevention of emergence of outbreaks in non-endemic areas. Objectives: The aim of this study was to detect the presence of LASV RNA in different species of rodents in Ikorodu, Lagos state and Abeokuta, Ogun state. Methods: A total of ninety one (91) rodents were captured from Ikorodu, Lagos State (61 rodents) and Abeokuta, Ogun State (30 rodents), euthanized, bled, and plasma obtained for the detection of LASV RNA by Reverse Transcriptase Polymerase Chain Reaction. Results: A total of 91 rodents consisting of 77 Rattus rattus and 14 Crocidura spp. The S segment of LASV RNA was not in any of the 91 rodents’ plasma samples. Conclusion: The rodents captured within the rural communities of Ikorodu, Lagos State and Abeokuta, Ogun State were found not to habour the LASV RNA. This study is limited by the relatively small sample size. Similar studies should be encouraged both in endemic and non-endemic areas in order to understand the actual burden of Lassa fever as well as put into check future epidemics.

Syringa pubescens Turcz ethyl acetate extract improves non-alcoholic steatohepatitis by regulating the Nrf2， IκBα and TGF-β1 signaling pathways

Food Science and Human Wellness 2024年

作者： Weidong Xu Yanfang Wu Jiameng Zhang Zichen Zhang Xinyi Guan Suya Zhang Xinsheng Wang Pu Liu Enguo Fan College of Chemistry and Chemical Engineering， Henan University of Science and Technology College of Basic Medical and Forensic Medicine， Henan University of Science and Technology Department of Microbiology and parasitology， institute of Basic Medical Sciences， Chinese Academy of Medical Sciences/School of Basic Medicine， Peking Union Medical College

The flower of Syringa pubescens Turcz. （SP）， was used as both medicine and food in China， exhibited a variety of biological activities. However， it remains unknown whether SP has an effect on ameliorative nonalcoholic fatty liver disease （NASH）. In this study， the improvement of SP ethyl acetate extract （SPE） on NASH was evaluated and the potential mechanisms were explored. The glycosides of SPE were determined by an HPLC method. HepG2 cell lines were treated with free fatty acid to clarify the improvement effect and mechanisms of SPE on NASH in vitro. C57BL/6J mice were treated by 60 kcal% high-fat diet （HFD） combined with carbon tetrachloride (CCl4) to establish the NASH model in vivo. The results showed SPE could inhibited the hepatic injury and lipid steatosis by decreasing the levels of ALT， AST， TG and TC in vitro and vivo. The SPE suppressed the oxidative stress and inflammation by restraining the generation of ROS， MDA， IL-1β， IL-6 and TNF-α and enhancing the activity of antioxidant enzymes including SOD， CAT and GSH-Px in NASH model. Moreover， SPE declined the level of fibrosis markers including HYP， Col Ⅰ and α-SMA in HFD combined CCl4（HC）-induced mice. Mechanically， SPE inhibited hepatocellular Keap1 expression and promoted Nrf2 nuclear translocation， which suppressing the phosphorylation of IκBα/NF-κB. In addition， SPE down-regulated the level of TGF-β1 and phosphorylation of Smad2 to mitigate fibrosis. In brief， SPE could significantly alleviate lipid accumulation， oxidative stress， inflammation and fibrosis via regulating Nrf2/HO-1， IκBα/NFκB and TGF-β1/Smad2 pathways in the progression of NASH， which indicated that SPE had the potential to be a novel and effective drug or food supplements for the improvement of NASH.

The current study was performed to evaluate the liver function status as well as molecular characterization of the recovered worms in rats experimentally infected with F. hepatica. Sixteen male Wister rats aged 30 days were randomly allocated into two groups (n = 8). The first group was infected orally with 15 viable encysted metacercaria of F. hepatica per animal. The other group was kept non-infected (control group). At zero time (before infection), the 2nd, 4th, 6th, 8th, 10th, 12th and 14th weeks post-infection (WPI), blood and serum samples were collected via puncture of retro-orbital plexus of veins from each rat. Serum enzyme level (AST and ALT) and total protein were measured, and the serum protein profile was carried out using agarose gel electrophoresis. During the period of the experiment, serum ALT and AST activities and serum total globulins significantly increased while serum total proteins and albumin markedly decreased in the infected group. On the 14th WPI, the data of the electropherogram showed that globulin fractions (α1-, β- and γ-globulin) levels were significantly increased while α2-globulin was markedly decreased in the infected group. The molecular analysis confirmed the amplification of the ITS1, ITS2 and NDI genes of F. hepatica recovered from the infected liver of rats with amplicon sizes of 630, 510 and 560 bp, respectively. Sequencing of the amplified ITS gene resulted in the determination of 3 strains (PP108836, PP108837, and PP108838). Also, analysis of the ITS2 gene resulted in obtaining 3 isolates under the accession numbers (PP109065, PP109066, and PP109067). In conclusion, fasciolosis in the rat model is suitable for routine experimental infections and caused a pronounced liver dysfunction with discharging of the Fasciola eggs in the faeces and the development of adult stages in the bile ducts. Furthermore, molecular techniques are a sensitive

Rotavirus is the leading cause of acute gastroenteritis and responsible for 20% of death in children under 5 years of age approximately 111 million episodes of gastroenteritis due to Rotavirus in under 5 children, which result in 25 million visits to clinic, 2 million hospitalization and 352,000 - 592,000 deaths. Children in the poorest countries account 82% of rotaviruses death. Diarrhea disease are major cause of death and disease among children under five years, a child on average suffers 2 to 3 attacks of diarrhea every year. Stools samples were collected from 196 children suffering from diarrhea and were tested for rotaviruses by immune chromatography test antigen (ICT-Ag), ELISA and RT PCR The data were analyzed using statistical package for the Social Sciences (SPSS). The results showed that prevalence of rotavirus was 26/196 (13.3%) by ICT Ag and ELISA and confirmed by RT-PC R. 87.8% of the children were vaccinated by Rota vaccine, 70% of their mothers not using soap for cleaning the children and thought diarrhea not infectious disease and believed it was caused by teething. In conclusion there was a decrease in prevalence of diarrhea by Rotavirus due to insertion of Rota vaccine in routine vaccination, rotavirus infection mostly occurs in poor family that not able to provide safe water and due to poor sanitation and low education of mother beside that some children suffered from malnutrition, so it recommended to incorporate ELISA as a diagnostic tool in routine diagnosis of rotavirus among children suffered from gastroenteritis.
