RESUMO

Hepatitis B viral infection could be complicated by hepatocellular degeneration, liver cirrhosis, and cancer. A total of 87 participants - 29 each of symptomatic and asymptomatic hepatitis B positive, and hepatitis B negative individuals (controls) - were recruited, and their serum samples were evaluated for serum telomerase (a biomarker for cell aging and tumorigenesis), alpha fetoprotein, and liver enzymes. Serum telomerase of the symptomatic group was higher than that of the asymptomatic group and the control (P < .001). Serum α-fetoprotein in the symptomatic group was also higher than the asymptomatic group and the controls (P < .001). The mean AST value for the symptomatic test group was higher than the asymptomatic test group and the control (P < .001). The mean ALT value for the symptomatic test group was higher than the asymptomatic test group and the control (P < .001). However, serum α-fetoprotein, AST, and ALT in the asymptomatic group were not significantly different from the controls. Serum telomerase activity was higher in symptomatic and asymptomatic HBV subjects compared with controls; this provides better information than AFP and liver enzymes that were only higher in symptomatic subjects. Serum telomerase activity could therefore be used as a marker in predicting the onset of hepatocarcinogenesis.Abbreviation listHBV: Hepatitis B virus; AFP: Alpha fetoprotein; ALT: Alanine transaminase; AST: Aspartate transaminase; HCC: Hepatocellular carcinoma; ELISA: Enzyme-linked immunosorbent assay; CLD: Chronic liver disease; CMV: Cytomegalovirus; TERT: Telomerase reverse transcriptase; TERC: Telomerase RNA component; WHO: World Health Organization; BUHREC: Babcock University Health Research Ethics Committee; CTL: Cytotoxic T-lymphocyte.

RESUMO

The data employed the blend of waste used oil and beef tallow for the synthesis of fatty acid ethyl ester (FAEE) via ethanolysis of developed catalyst from calcined fermented cocoa pod husk powder (CFCPHP) doped with burnt cocoa pod husk powder (BCHP). Characterization of the developed doped catalyst (DDC) was carried out using FTIR, SEM, XRD, and BET adsorption analysis, while the basic strength of the DDC was tested through reusability test data. Mathematical optimization of the process condition was carried out through Box-Behnken Experimental Design (BBED) in 29 runs with variations in four variables as catalyst concentration (1.5 to 3.5 wt.%), reaction time (60 to 100 min), ethanol/oil molar ratio (EtOH/OMR) of 3 to 7, and reaction temperature (60 to 80 °C). The FAEE quality was ascertained by determining its fuel properties. The data showed that the binary blend ratio of 42:58 of Waste Used oil: Beef Tallow oil (WUO: BTO) was obtained through API gravity ratio formulation. The developed doped catalyst (DDC) produced a high CaO-base of 84.30 (wt.%), with a high total basic site of 210 µmole.g-1 via BET and XRD analysis. The SEM analysis dataset showed non-uniform sizes, highly porous and crystalline sample, while the dataset on FTIR analysis data confirmed the presence of wagging and twisting CO3 2-, the bending vibration of O-Ca-O, the sp2 of C = O, C = C, the sp of C  ≡  C and C  ≡  N, the bending structure of O-H, and the O=O, N ≡ O of Amines, and Amides. Based on the experiment, the maximum experimental yield of 97.80 (%wt.) at runs 7, and low yield of 89.50 (%wt.) at run 17 was obtained for FAEE. Mathematical optimization in 10 solutions predicted the FAEE yield of 97.7999 (%wt.) at the catalyst concentration of 3.10 (wt.%), the reaction time of 68.09 min, the EtOH/OMR of 3.01, and the reaction temperature of 72.21 °C. This data was validated in replicate, and the average mean value of FAEE was 97.68 (%wt.). Dataset on ANOVA and parametric analysis showed that the variable factors considered were significant at p-value <0.0001, with high R2 of 99.14%, R2-predicted of 98.32%, R2-adjusted of 98.28%, and adequate precision of 51.152, respectively. Catalyst reusability test data showed that the cycle number was stopped at the 5th cycle due to the decrease in catalyst basic strength. The produced FAEE dataset was within the recommended standard, and the data showed the developed doped catalyst successfully converted binary blend oil to FAEE, and the fermentation process increased the CaO-based conversion of DDC.
