The research assessed the effectiveness of removing the harmful anionic Direct orange 39 dye using CoFe2O4/AC/ PANI nanocomposite as a novel and economical nanoadsorbent. This nanocomposite synthesized through chemical coupling and polymerization method for CoFe2O4 with Active carbon (AC) and polyaniline (PANI). The chemical coupling of composite components performed in ammonium persulfate solutions to create monomer that polymerizations in aqueous acids. Infrared spectroscopy proved the CoFe2O4 nanoparticles synthesized as an inverse spinel via characteristic peaks between 600 and 400 cm-1, which indicating to the locations of tetrahedral Fe-O and octahedral Co-O. X-ray diffraction conformed that the synthesis ternary composite has nanoscale size 36 nm. The BET surface areas and pore size distribution demonstrated are 54.118 m2 g-1 and 8.9064 m2 g-1, respectively. The hysteresis loops of adsorption isotherms are type IV, with relative pressure range (P/P0) of 0.3~1.0, which belongs to type H3 with nanopores. Initially, the adsorption experiment was carried out for this superimposed surface towards the direct orange 39 dye and found high removal dye percentage of 95% at 45 min, surface mass at 0.3 g, and pH 6. The composite surface shows the adsorption kinetics of direct orange 39 dye that can be effectively described by the pseudo-first order model. On the other hand, the thermodynamics functions were detected and found the removal reaction of dye using composite was demonstrated a chemical adsorption (greater than 80 kJ/mol) with endothermic reaction.

The code on plastic water bottles and food container’s items appears as a triangle with a number between 1 and 7. The understanding of the seven plastic codes is very important for the people to decide the reusing plastic and food containers to know which plastics can be recycled. This study is aimed to investigate the level of people’s education toward this matter and to raise the awareness of the dangers of reusing plastic water bottles and food containers items as containers for storage of food and water. A questionnaire containing three different groups of questions was distributed for people working in chemistry field. The people are undergraduate student, postgraduate students and staff member. The results indicate that there is a lake of education about the dangers of reusing plastic water bottles and food container’s items. Only one staff member has an excellent knowledge about these concerns. This person specializes in organic chemistry and was studied polymer in his postgraduate study. The study is concluded helping to keep the people away from dangerous diseases. The numbers of the persons that shared in this questionnaire are 62 persons; this number was consisted of 35 males and 27 females.

MicroRNAs (miRNAs) are small, non-coding RNA molecules that represent the foundation of gene expression modulation, thereby controlling numerous biological processes. In this review, we discuss the diverse roles of miRNAs in relation to human health by focusing on their regulation of cellular processes like proliferation, differentiation, and apoptosis. The dysregulation of miRNA expression has been associated with a variety of diseases, such as cancer, cardiovascular disease, and neurodegenerative disease, highlighting their importance as biomarkers and as possible therapeutic targets. This review discusses the mechanism through which miRNAs influence gene networks, their role in post-transcriptional regulation, and how they target messenger RNAs (mRNAs). Moreover, the therapeutic potential of miRNAs is elaborated, with considerations of miRNA replacement and inhibition approaches from a clinical perspective. Advances in miRNA therapies, including the development of nanocarriers for site-specific delivery, contribute to the progress of future treatment modalities.Lastly, this review highlights the need to understand miRNA biology for the determination of disease mechanisms as well as the design of new diagnostic and therapeutic strategies. With their diverse functions, a deeper understanding of miRNAs not only enhances our knowledge of molecular biology but also has the potential for breakthroughs in precision medicine.

The take a look at highlights the potential of making use of agricultural by way of-merchandise for sustainable nanoparticle synthesis and their packages in environmental remediation. This paper offers a green synthesis method for (CeO2) nanoparticles the use of ethanol extract from Citrus aurantium peels sourced from Al-Hussainiyah, Iraq. The green synthesis method leverages the herbal antioxidant of Citrus aurantium peels, presenting a sustainable and green alternative. The synthesized CeO2 nanoparticles have been characterized the usage of numerous techniques, along with FTIR spectroscopy, XRD, FE-SEM with (EDX) and BET. The nanoparticles exhibited like-rose berry morphology with a mean crystal size of 12 nm and excessive crystallinity. BET analysis indicated a specific surface area of 173.309m²/g and a mean pore diameter is 3.06nm, ensuring a mesoporous structure. The perfect removal of 10 ppm of eosin yellow dye using 0.025 g of CeO2 NPs turned into pH 6 at 90 min which agreed with zeta potential analysis, and the adsorption process followed pseudo-second-order kinetics. The ΔHo of adsorption is 13.430 kJ/mol due to this reaction being physical adsorption. The reusability study showed the CeO2NP could be successfully used up to the 3rd cycle before a loss of 50% from efficiency.

Background: Celiac disease (CD) is an autoimmune enteropathy triggered by gluten in genetically susceptible individuals. The WNT signaling pathway maintains intestinal epithelium homeostasis. This study evaluated two WNT antagonists (Dickkopf-1 and sclerostin) in CD patients with varying intestinal atrophy (Marsh scores) compared to controls. A lipid profile blood test measures the total amount of cholesterol in your blood (total cholesterol) the level of HDL-cholesterol (high-density cholesterol, often called ‘good cholesterol the level of LDL-cholesterol (low-density cholesterol, often called ‘bad’ cholesterol triglycerides (TG, another type of fat in the body) LDL cholesterol is referred to as bad cholesterol because it can build up in the walls of your blood vessels, This increases your risk of coronary heart disease and atherosclerosis HDL cholesterol is good cholesterol because it removes excess cholesterol from your body. High triglyceride levels can also increase your risk of cardiovascular (heart and blood vessel) diseaseMethods: 43 CD patients and 45 controls were enrolled. Serum levels of Dickkopf-1, sclerostin, citrulline, PTH, calcium, and vitamin D3 were measured via ELISA, spectrophotometry, and HPLC.Results: Dickkopf-1 (P<0.0001) and sclerostin (P=0.002) were significantly elevated in CD. PTH (P<0.0001) and calcium (P=0.009) were also higher. Citrulline correlated with sclerostin (R=0.71), PTH (R=0.53), and Dickkopf-1 (R=0.29). ROC analysis showed Dickkopf-1 (AUC=0.83), sclerostin (AUC=0.7), and PTH (AUC=0.91) differentiated CD from controls but not atrophy severity. Conclusion: Elevated WNT antagonists and PTH in CD correlate with enterocyte mass markers, suggesting their pathogenic role. Further studies are needed for diagnostic/therapeutic applications.
