The infection with H. Pylori stimulates a signaling cascade that causes the generation of Cytokines and provokes Oxidative stress that is involved in the chronic inflammatory response leads to Gastric cancers. Reactive oxygen species (ROS) produce 8-Hydroxydeoxyguanosine (8-OHdG), the persistent oxidative DNA damage product. The study objective was to assess if there was a link between inflammatory cytokine levels and the presence of Oxidative DNA damage in Gastric tumor patients. In addition, evaluation of the diagnostic and prognostic value of Oxidative DNA damage and inflammatory cytokine biomarkers for Stomach cancers is being conducted. The study was accomplished on medically diagnosed Stomach cancer patients before any form of treatment. A total of 33 patients with Gastric cancers were selected and divided into Stages I, II, and III according to clinical pathology, and 32 age-matched healthy subjects as a control group. The Serum 8-OHdG, IL-6, TNF-α, IFN-γ & CEA were evaluated. The results revealed a highly significant rise (P<0.0001) in blood levels of 8-OHdG, TNF-α, & IFN-γ, and a non-significant (P=0.4747) increasing in IL-6 in GC patients compared to Controls, with levels gradually increasing as disease stages progressed. Furthermore, in GC patients, there was an insignificant (P=0.3472) positive correlation (r=0.1292) among 8-OHdG, IL-6, and CEA levels, but a noteworthy (P<0.0001) positive correlation (r=0.7235) among 8-OHdG, TNF-α, and CEA levels. In GC patients, however, there was an insignificant (P=0.6342) negative correlation (r=-0.06559) among 8-OHdG, IFN-γ, and CEA levels. The results of the current study show a strong link between serum levels of the 8-OHdG as well as inflammatory cytokines in GC patients. The significant enhancement in oxidative DNA damage, as well as overexpression of inflammatory cytokine biomarkers and CEA in the blood suggests that Oxidative stress and chronic inflammation are included in GC carcinogenesis. These observations suggest that 8-OHdG, TNF-α, & IFN-γ are viable biomarkers for the Gastric tumor prediction.

Humans always mount a robust immune response to the bacterial infection caused by Helicobacter pylori, which causes various gastrointestinal tract infections. Calprotectin (CALP) and B-Cell Activating Factor (BAFF) are inflammatory biomarkers having a role in the gastrointestinal neutrophilic response to bacterial infection. The study was designed to assess serum CALP and BAFF as inflammatory biomarkers in H. pylori infection and peptic ulcer patients. The current study comprised 112 people, including 62 H. pylori-infected patients (34 men and 28 women) who were clinically diagnosed with H. pylori infection via testing positive for the H. pylori stool antigen test; they were compared to a control group of 50 healthy people (34 men and 16 women) who were age and gender-matched to H. pylori-infected patients. The serum level of CALP and BAFF were assayed using the ELISA technique. The biochemical parameters were statistically compared between patients and controls by unpaired Man-Whitney U t-test and Receiver Operating Characteristic (ROC) curve analysis. There was a significant elevation of serum CALP in H. pylori-infected patients [116.4(120.7), p=0.0132] in comparison to healthy controls [99.50(115.8)]. Similarly, there was a significant elevation of serum BAFF concentration in H. pylori-infected patients [485.7(367.1), p=0.0014] in comparison to healthy controls [444.5(513.0)]. The ROC curve analysis suggests serum CALP and BAFF as reasonable inflammatory biomarkers for H. pylori infection with statistically significant (p=0.0135, p=0.0015) area under the ROC curve of (0.6361, 0.6748), respectively. CALP and BAFF are potent inflammatory biomarkers involved in the development and etiology of H. pylori infection. Serum CALP and BAFF levels could be used as biomarkers for chronic inflammation induced by H. pylori. CALP and BAFF biomarkers can be combined to diagnose and predict the prognosis of H. pylori infection.

Objective: The purpose of this research was to assess the serum concentration of (1,25-(OH)2D3) and trace elements in patients with rheumatoid arthritis as compared to healthy individuals. Methods: This research was performed on 72participants, 37 cases of RA and 35 healthy individuals, with age range 39-67 years. Serum (1,25-(OH)2D3) levels was determined and compared in cases and healthy controls. Results: The serum (1,25-(OH)2D3) levels were significantly lower in the RA patients (13.24 ± 1.06 ng/ml), when compared to the healthy individuals (26.9 ± 1.7 ng/ml). The examination of data revealed that the levels of (Magnesium, Manganese, Nickel and Rubidium) were remarkably elevated in RA patients when compared to healthy control , serum levels of (Chromium, Cobalt and Germanium) were remarkably decreased in RA patients  when compared to healthy control. Conclusions: (1,25-(OH)2D3) insufficiency is more widespread among patients with RA and may be one of the reasons leading to evolution of rheumatoid arthritis. Supplementation with (1,25-(OH)2D3) may be required both for the avoidance of bone loss besides for painkilling in patients suffering from rheumatoid arthritis. Current results propose that alterations in the serum concentration of trace elements may yield  good indication  to their role in the pathogenesis of  rheumatoid arthritis.

Objectives: This study set out to determine how Calprotectin and B cell activating factor contributes to early COVID-19 patient severity prediction. Methods: The study included 25 healthy controls and 52 patients with SARS-COV2 infection who were clinically diagnosed with COVID-19 illness and were between the ages of 23 and 35. The serum levels of CALP and BAFF were measured using the ELISA method. To gauge CRP levels, an immunoturbidometric assay was performed. Results: Variations in serum levels of CALP and BAFF were found to be statistically insignificant in the study (P=0.7109 & P=0.7575, respectively). When compared to the control group (103.95±36.67 ng/mL; 403.03±1.03), COVID-19 patients had non-significantly raised levels of CALP and BAFF (106.5±4.67 ng/mL; 436.9±12.77 pg/mL, respectively). According to ROC curve analysis, the area under the receiver operating characteristics curve (AUC) for CALP and BAFF was (0.5170) and (0.5259), respectively. (r=0.6923; P=0.0001). There was a significant positive correlation between serum CALP and BAFF levels. The connection between serum CRP levels and CALP (r=0.3010; P=0.1271) and BAFF levels (r=0.2912; P=0.1406) was insignificantly positive. Conclusion: The current study's findings suggested that serum CALP and BAFF concentrations were increased in COVID-19 patients, suggesting that these inflammatory markers may be helpful indicators of the severity of COVID-19.

Flavonoids are phytochemical compounds that can be found in a wide range of plants, including vegetables, fruits, and leaves. This vast set of phenolic plant elements can be split into numerous classes based on their diverse structures, including Flavanones, Flavanols, Flavonols, Flavones, Isoflavones, and Anthocyanins. Interestingly, they possess various applications such as natural dyes, medicinal uses, and food sources. Flavonoids have been shown to have anti-cancer, antioxidant, anti-inflammatory, and anti-viral properties in clinical studies. They also have cardio-protective and neuroprotective effects. In addition, they are responsible for the presence of different colors and flavors in various fruits, flowers, and food sources. Multiple spectroscopic techniques, including Infrared spectroscopy (IR), Ultraviolet spectroscopy (UV), and Nuclear magnetic resonance (NMR) spectroscopy, are being used to identify the structure of flavonoids. UV-Vis spectroscopy data can be used to estimate the position, type, and number of substituents present in a conjugated system. IR spectroscopy is primarily used to determine the type of functional groups and aromatic ring substitutions. The structure of Flavonoids, their type, number of protons, and carbons can be determined by NMR spectroscopy. The current review was based on searches of the Scopus, Web of Science, and Google Scholar databases for literature reviews. The purpose of this review article is to demonstrate the structure, function, and different extraction methods of flavonoids. It also summarizes the isolation and analytical identification techniques for flavonoids.
