The biological functions of miRNAs have been explored considerably. Numerous studies have demonstrated that extracellular miRNA could be implemented as a biomarker for several diseases. Nonalcoholic fatty liver disease (NAFLD) has become one of the leading causes of chronic liver disease worldwide. NAFLD embodies an array of defects extending from elementary steatosis to nonalcoholic steatohepatitis, which might advance to fibrosis, cirrhosis, and even hepatocellular carcinoma, which are closely linked to increased activity hepatic morbidity and mortality. Liver biopsy is acknowledged as the most precise practice for diagnosis and staging of NAFLD. Invasive drawbacks have prompted the likelihood of introducing an alternative noninvasive approach for consideration. Several lines of evidence have revealed that miRNAs are emerging as a potentially useful noninvasive marker for the development and progression of NAFLD. In addition, recent studies have identified that miRNAs take part in lipid metabolism linked to NAFLD and its advancement to severity. This article reviews the contemporary corroboration associating miRNAs and NAFLD and emphasizes the potential role of miRNA as a circulatory biomarker that could alert the growing prevalence of NAFLD. Furthermore, it acknowledges the valuable compendium of information regarding biogenesis and the role of circulating miRNA in lipid metabolism, which is intimately linked to NAFLD.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"7 1","pages":"1 - 8"},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42468190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since our previous studies demonstrated that the general Bufo bufo skin secretions induced platelet aggregation in platelet-rich plasma, this work was designed to study the effects of the components of some fractions on platelet functions to comprehend its possible mechanism of action as platelet modulators. Methods: Chromatographic separation of B. bufo general skin secretions was carried out using size exclusion chromatography. Rabbit platelets were purified by column chromatography on Sepharose 4B. Various aspects of platelet function such as activation, aggregation, and adhesion were evaluated. Results: One fraction, out of 7, dose-dependently induced aggregation of isolated platelets and was used in further experiments. The studied fraction was shown to induce platelet adhesion onto fibrinogen-coated surface. Furthermore, the results demonstrated the effects of the fraction on some processes that involved in platelets activation: The fraction components facilitated (Ca2+) i mobilization and attenuated platelets Akt phosphorylation, but had no effect on platelet serotonin secretion. Membrane integrity was determined using lactate dehydrogenase (LDH) assay. No increased LDH release was recorded that means no platelet damage, which could lead to misinterpretation of the data, occurred. Conclusion: The results suggest that components of the B. bufo skin secretions may be a promising source of natural compounds which can modulate platelet functions.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"7 1","pages":"60 - 66"},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48499749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although effective preventive measures are still lacking, features of positive mental health and emotional resilience have the potential to reduce the risk of neurodegenerative diseases (NDDs). Romantic experiences – which are characterized by intense emotional intimacy – have complex biological underpinnings including an increased production and release of oxytocin and nerve growth factor (NGF). Because both oxytocin and NGF can protect against neurodegeneration, we propose our hypothesis that being constantly engaged in romantic feelings and experiences may delay or even prevent the onset of NDDs. We also propose that this could occur at the molecular level through the NGF/protein kinase B (Akt)/cyclic-adenosine monophosphate response element-binding protein and NGF/Akt/phospholipase C-gamma (PLC-γ) signaling pathways.

MMPs are thought to control the activity of a number of non-ECM bioactive substrates, such as growth factors, cytokines, chemokines, and cell receptors, which control the tissue microenvironment. The interaction between cells and ECM plays a key role in normal development and differentiation of organism and many pathological states as well. The primary class of controlling proteases in the ECM is known as MMPs. Aspects of normal physiology and pathology depend on the ability of MMPs to change the structural integrity of tissues. Uncontrolled ECM turnover, tissue remodeling, inflammatory response, cell proliferation, and migration are pathogenic alterations that can result from an imbalance between the concentration of active metalloproteinases and their inhibitors (tissue inhibitors of metalloproteinases [TIMPs]). This detailed review provides some information on the function of MMPs in inflammatory, caries and periapical, cancer, and other oral diseases. Blood and saliva are the two biological fluids that are most frequently used to diagnose oral disorders. Most of the ECM components in patients undergo digestion to lower molecular weight forms, resulting in much higher amounts of MMPs in their saliva/blood than in healthy individuals. Conventional treatment successfully reduces the levels of MMPs which inhibits the progressive breakdown of collagens in ECM components.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"7 1","pages":"17 - 23"},"PeriodicalIF":1.4,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47106685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to a lack of data, the overall impact of AMR in Libya is not well known or documented. As a result, this study presents the results of a review of available data on AMR in Libya over the past 20 years (from 2002 to 2021) to aid understanding of the current AMR situation in this portion of the continent. Methods: Articles related to the topic were researched using databases and search engines such as PubMed, Google Scholar, and ResearchGate websites. These articles were selected based on predetermined inclusion and exclusion criteria. The total number of tested isolates for each of the reported Bacterial spp. was used to calculate antibiotic resistance to a specific bacterium. Results: Studies published in the past 20 years, representing reports of 18,160 AMR tests, showed that Urinary Tract Infection (UTI) was the most reported clinical diagnosis in Libya (61.3%). Out of 43 articles, Staphylococcus aureus was the most common Gram-positive bacteria documented in (31, 61.3%) studies, and was most common in 59.78% of skin infections. Whereas, Pseudomonas spps., were the most common Gram-negative bacteria presented in (23, 53.48%) studies, and were commonly isolated in respiratory infection (9.39%). Among Gram-negative bacteria, Pseudomonas spp. reported a high resistance percentage for penicillin beta-lactam antibiotic, i.e., piperacillin (10.4%) and to the first-generation cephalosporins antibiotics, i.e., cefazolin (7.7%). However, they are susceptible to metronidazole, vancomycin, and colistin. Gram-positive bacteria, S. aureus shows high resistance to oxacillin, followed by gentamycin and cefoxitin (8.5%, 8.3%, and 8.3%, respectively). Effective antibiotics against S. aureus were azithromycin, clarithromycin, and metronidazole, whose susceptibility was 99.9% each, while 1% of S. aureus were vancomycin-resistant S. aureus. Conclusion: This study gives a comprehensive analysis of the state of AMR in Libya with respect to the most regularly prescribed antibiotics. The findings of the research show the alarmingly persistent occurrences of AMR in Libya, as well as the critical need to establish national action, plans to combat AMR and improve surveillance programs.","PeriodicalId":36500,"journal":{"name":"Biomedical and Biotechnology Research Journal","volume":"6 1","pages":"473 - 482"},"PeriodicalIF":1.4,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44012078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Western blotting was performed to determine the expression of BCL11A, KLF1, and ERK of the MAPK pathway. Results: In contrast to HU, the treatment with SCF and EPO, either separately or together, preserved the expression of the γ-globin gene. In addition, SCF and EPO treatment had no effect on the expression of BCL11A or KLF1 in K562 cells. After receiving SCF and EPO treatment, the ERK signaling of the MAPK remained unaltered.
