The primary outcome highlights the sensitivity and specificity of single diagnostic biomarkers studied in blood or stool. The secondary outcome reveals the sensitivity and specificity of the biomarkers panel (combinations) in blood or stool. While some markers show better performance, others are not suitable for screening purposes.
There is a need to adjust experimental and analytical tests that can interfere with a robust result to replace or supplement those markers that are currently in use. Nevertheless, robust verification and validation with large clinical cohorts are needed for successful noninvasive tests that can fulfill the role of colonoscopy.

Due to the strong association between the chemistry of medicinal plants and their biological properties, it is important to determine their phytochemical composition to justify experimental tests.
The aim of this study was to evaluate the in vitro antioxidant and the enzyme inhibitory properties and to identify the bioactive compounds present in the extracts of Ephedra nebrodensis growing in Algeria.
Total phenolic and flavonoids content in these extracts were quantified by Folin- Ciocalteu and aluminum chloride methods. The antioxidant capacity was assessed using DPPH, ABTS, β-carotene/linoleic acid, CUPRAC and FRAP assays, and in vitro cholinesterase activity against acetylcholinesterase and butyrylcholinesterase were evaluated. The chemical constituents of the extracts were analyzed by high-performance liquid chromatography coupled with mass spectrometric detection and gas chromatography. For the acute toxicity study, extracts were administered to mice at single dose of 2 g/kg and 5 g/kg by gavage.
Plant extracts were rich in phenolic compounds. Ethyl acetate extract presented the highest phenolic (238.44 ± 1.50 μg GAE /mg of extract) and flavonoid (21.12 ± 0.00 μg QE /mg of extract) contents. Capsazepine purchase Likewise, ethyl acetate extract showed potent radical scavenging and reducing properties. Ethanol-acetone extract showed inhibitory activity against acetylcholinesterase, and was a potent inhibitor of butyrylcholinesterase. In all extracts, flavonoids were the most abundant compounds. The phytochemical investigation showed the presence of alkaloids (ephedrine and pseudo-ephedrine). In the acute toxicity, the LD
was superior to 5 g/kg body weight. There were no alterations in the histology of the liver and kidneys.
This study demonstrated a good antioxidant potential and anticholinesterase activity of aerial parts of E. nebrodensis.

Epithelial-mesenchymal transformation (EMT) promotes cancer metastasis, including hepatocellular carcinoma. Therefore, EMT-related gene signature was explored.
The present study was designed to develop an EMT-related gene signature for predicting the prognosis of patients with hepatocellular carcinoma..
An integrated gene expression analysis based on tumor data of the patients with hepatocellular carcinoma from The Cancer Genome Atlas (TCGA), HCCDB18, and GSE14520 dataset was conducted. An EMT-related gene signature was constructed by the least absolute shrinkage and selection operator (LASSO) and COX regression analysis of univariate and multivariate survival.
A 3-EMT gene signature was developed and validated based on gene expression profiles of hepatocellular carcinoma from three microarray platforms. Patients with a high-risk score had significantly worse overall survival (OS) than those with low-risk scores. The EMT-related gene signature showed a high performance in accurately predicting prognosis and examining the clinical characteristics and immune score analysis. Univariate and multivariate Cox regression analyses confirmed that the EMT-related gene signature was an independent prognostic factor for predicting survival in hepatocellular carcinoma patients. Compared with the existing models, our EMTrelated gene signature reached a higher area under the curve (AUC).
Our findings provide novel insight into understanding EMT and help identify hepatocellular carcinoma patients with poor prognosis.

Recent reports showed that there is a direct causal link between inflammation and cancer development, as several cancers were found to be associated with chronic inflammatory conditions. In patients with cancer, healthy endothelial cells regulate vascular homeostasis, and it is believed that they can limit tumor growth, invasiveness, and metastasis. Conversely, dysfunctional endothelial cells that have been exposed to the inflammatory tumor microenvironment can support cancer progression and metastasis. Dysfunctional endothelial cells can exert these effects via diverse mechanisms, including dysregulated adhesion, permeability, and activation of NF-κB and STAT3 signaling. In this review, we highlight the role of vascular inflammation in predisposition to cancer within the context of two common disease risk factors obesity and smoking. In addition, we discuss the molecular triggers, pathophysiological mechanisms, and the biological consequences of vascular inflammation during cancer development and metastasis. Finally, we summarize the current therapies and pharmacological agents that target vascular inflammation and endothelial dysfunction.Potential sex-related differences in the periprocedural and long-term postprocedural outcomes of coronary angioplasty in patients with stable coronary artery disease have been studied thoroughly over the last few decades, to determine whether female sex should be regarded as an independent risk factor that affects clinical outcomes. Based on a significant number of observational studies and meta-analyses, sex has not yet emerged as an independent risk factor for either mortality or major cardiac and cerebrovascular events, despite the fact that in the early 1980s, for several reasons, female sex was associated with unfavourable outcomes. Therefore, it remains debatable whether the female sex should be considered as an independent risk factor for periprocedural and long-term bleeding events. The pharmacological and technological advancements that support current coronary angioplasty procedures, as well as the non-delayed treatment of coronary artery disease in females, have certainly lessened the outcome differences between the two sexes.
