Preparation and optimization of grafted hydroxyethyl cellulose, polypyrrole, and nitrogen-doped carbon quantum dots bionanocomposites for electrical, optical, and photoluminescence multicoloring applications.

The major objective of this research revolves around the integration of polypyrrole (PPy) and various concentrations of nitrogen-doped carbon quantum dots (N-CQDs) into a polyacrylamide (PAm)-grafted hydroxyethyl cellulose (gHEC) to produce gHEC@PPy@N-CQDs bionanocomposites that possess environmentally sustainable properties. The intercalation and uniform distribution of N-CQDs inside the gHEC@PPy matrix have been demonstrated through the analysis of data obtained from X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The samples underwent analysis using thermogravimetric analysis (TGA and DTG) as well as scanning and transmission electron microscopy.

Emerging Role of Circular RNAs in Hepatocellular Carcinoma Immunotherapy.

Hepatocellular carcinoma (HCC) is a highly fatal malignancy with limited therapeutic options and high recurrence rates. Recently, immunotherapeutic agents such as immune checkpoint inhibitors (ICIs) have emerged as a new paradigm shift in oncology. ICIs, such as programmed cell death protein 1 (PD-1) inhibitors, have provided a new source of hope for patients with advanced HCC.

Synthesis and characterization of bio-nanocomposite based on chitosan and CaCO nanoparticles for heavy metals removal.

Water is a vital component of life; therefore, it is critical to have access to pure water for various life-sustaining activities including agriculture and human consumption. An eco-friendly nanocomposite based on chitosan (Cs) and nanomaterials (CaCO-NPs) were combined to amalgamate the advantages of biopolymers and nanomaterials to overcome the problems of instability, poor mechanical properties, and low removal percentage of biopolymers. The as-prepared samples were characterized and were used for the removal of heavy metal from wastewater.

Decoding hepatocarcinogenesis from a noncoding RNAs perspective.

Being a leading lethal malignancy worldwide, the pathophysiology of hepatocellular carcinoma (HCC) has gained a lot of interest. Yet, underlying mechanistic basis of the liver tumorigenesis is poorly understood. The role of some coding genes and their respective translated proteins, then later on, some noncoding RNAs (ncRNAs) such as microRNAs have been extensively studied in context of HCC pathophysiology; however, the implication of long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs) in HCC is indeed less investigated.

Pharmacological updates of nifuroxazide: Promising preclinical effects and the underlying molecular mechanisms.

Nifuroxazide (NFX) is a safe nitrofuran antibacterial drug used clinically to treat acute diarrhea and infectious traveler diarrhea or colitis. Recent studies revealed that NFX displays multiple pharmacological effects, including anticancer, antioxidant, and anti-inflammatory effects. NFX has potential roles in inhibiting thyroid, breast, lung, bladder, liver, and colon cancers and osteosarcoma, melanoma, and others mediated by suppressing STAT3 as well as ALDH1, MMP2, MMP9, Bcl2 and upregulating Bax.
