Water sampling, Physical and chemical properties and Fungi population and diversity were determined using standard methods. Data generated were subjected to Analysis of Variance (ANOVA) and means were separated using Least Significance Differences (LSD) and Duncan Multiple Range Test. Result obtained revealed that Chanchaga irrigation water recorded the highest fungi population of 1.6 x 107 CFU/ml why fungi diversity was the least at Chanchaga. The presence of _Geotrichum species_ (2.33 x 106CFU/ml), _Candida tropicalis_ (4.33 x 106CFU/ml) and _Torulopsis glabrata_ (1.67 x 106CFU/ml) in water obtained from Mechanic village may be due to the presence of hydrocarbons in the oil polluting the water. They are potential degraders of crude oil hydrocarbons. They may therefore be responsible for the value of Biochemical Oxygen Demand of 261 mg/l recorded at Mechanic village. The Biochemical Oxygen Demand values of 342 mg/l and 360.00mg/l recorded at Fadikwe and Soje A respectively may be due to the presence of _Aspergillus niger.Aspergillus niger_ is a utility biological indicator of level of degradation of pollutant. These values were however higher than the Food and Agriculture organisation (FAO) standards for irrigation water. Further studies should however be carried out to investigate the bioremediating potentials of the fungi species identified in irrigation water obtained from Chanchaga.\u0000","PeriodicalId":503632,"journal":{"name":"Qeios","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140702383","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}

It further demonstrated how the contrasting ontological, epistemological assumptions and models of human beings the researcher brings to the research process have direct implications for one’s methodological concerns in a project. To ascertain these philosophical assumptions, thirty postgraduate projects were purposively selected and theoretical saturation determined the sample as depth was sought employing a grounded theory. Different Chapter 1s of various dissertations and theses were scrutinised first and used to develop a framework of analysis which was later fine-tuned using literature surveyed. Guided by an interactive process combining the elements of content and inductive thematic analysis, the major components of the study were identified, namely; the research problem, objectives, sub-problems or hypotheses. In turn, these influenced the literature surveyed, research methodology utilised, analysis and interpretation of data, conclusions drawn and recommendations made. These technicalities if carefully observed are meant to guide postgraduate students to produce a quality product independently and reveal the symbiotic relationship that exists between Chapter 1 and its subsequent Chapters in a dissertation or theses.\u0000","PeriodicalId":503632,"journal":{"name":"Qeios","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140699404","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}

It extracts high-dimensional quantitative features from medical images, providing information about cancer's phenotype, genotype, and tumoral microenvironment. This analysis could help avoid invasive procedures and help choose the most suitable therapeutic in multiple therapeutic options.\u0000\u0000METHOD: Radiomics has gained interest as an imaging biomarker for predicting response to various immunotherapies. Delta radiomics assesses feature variations from one time point to another based on subsequent images, offering higher value for treatment-outcome prediction or patient stratification into risk categories.\u0000\u0000CONCLUSION: It has potential benefits for clinical endpoints in oncology, such as differential diagnosis, prognosis, treatment response prediction, and evaluation of side effects. Further research with prospective and multicentre studies is needed for clinical validation of delta radiomics approaches.\u0000\u0000STATEMENT OF CLINICAL SIGNIFICANCE: In head and neck oncology, delta radiomics can be used to enhance the precision of diagnosis, assess tumor response, forecast normal tissue toxicity, predict clinical outcome, and pinpoint characteristics for treatment modification.

Properties of the Green’s function for the associated (p,q)-wave operator are derived based on contour integration. The notions of electric and magnetic fields in (p,q)-dimensions is explored by analogy with four dimensional physics and the problem of far field computation of the radiation field generated by charges and currents in ((1,n-1)) space-time is analyzed. SO(p,q) invariance properties of the Maxwell equations are deduced and used to formulate SO(p,q)-group theoretic image processing problems in (p,q)-dimensions. Dirac’s equation in (p,q)-dimensional space-time is derived using the Clifford algebra of the Dirac gamma matrices. SO(p,q)-invariance of the Dirac equation based on the spinor representation of (SO(p,q)) is mentioned. The Maxwell’s equations in (p,q)-dimensional curved space-time is analyzed using perturbation theory in the context of maximally symmetric spaces which play a fundamental role in ((p,q))-dimensional cosmological models for homogeneous and isotropic spaces. The Einstein-Maxwell equations for (p,q)-dimensional gravity and electromagnetism is studied and used to derive the equations of motion of point charges carrying mass moving under mutual gravitational and electromagnetic interactions in general relativity. Finally, Dirac’s equation in (p,q)-dimensional curved space-time interacting with the (p,q)-dimensional electromagnetic field is looked at. (U(1))-Gauge, local SO(p,q) Lorentz and diffeomorphism invariance of this equation is analyzed. Local (SO(p,q)) invariance of the curved space-time Dirac equation is deduced based on transformation properties of the Dirac matrices under the spinor representation.

This present study was aimed at assessing the phytochemicals and evaluating the hepatoprotective activity of leaf extract in Wistar rats. METHODS: The phytochemical screening was performed by standard methods, acute toxicity study and hepatoprotective activity were evaluated in randomly groups of five rats or six rats in paracetamol-induced liver toxicity. RESULTS: The phytochemical screening of leaf extract revealed the presence of major metabolites. The GC-MS analysis showed 18 bioactive compounds which are mainly fatty acids with retention times between 7.436 and 18.462 min. A high total phenolic content (TPC) of 1425.22 mg GAE/g and a total flavonoid content (TFC) of 802.01 mg QE/g were obtained. The acute toxicity did not produce any sign of toxicity at a dose of 5,000 mg/kg of extract. The extract produced a dose-dependent activity on the liver. These protections were statistically significant (p<0.05) when compared to the standard drug silymarin. There were no elevated values in liver function biomarkers in all the animal groups as well as histopathological damages to the liver after eight weeks of treatment at 200 and 400 mg/kg b.w. of extract doses. CONCLUSION: In conclusion, the study showed that C. sinensis methanol leaf extract contains important phytochemicals that are protective against paracetamol-induced liver injuries, thus, the plant was considered safe for use as ethnomedicinal remedies for liver disease in traditional medicine.\u0000","PeriodicalId":503632,"journal":{"name":"Qeios","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140711417","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}
