The latest studies have shown that long non-coding RNAs (lncRNAs) may be considered markers as their expression levels were abnormal in cancer and can be used as a molecular biomarker for the potential assessment of cancer prognosis. In this study, we aimed to assess the prognostic value of lncRNA as marker of patients with hepatocellular carcinoma. We performed a detailed search of the PubMed and Embase databases for articles on the prognostic value of various lncRNAs in HCC. We then carefully extracted the relevant data from the articles, and we used the meta-analysis method to analyze these results; heterogeneity and publication bias were also evaluated...

A new molecular biology based taxonomy has been proposed for pheochromocytoma and paraganglioma (PPGL). Data from the Cancer Genome Atlas revealed clinically relevant prognostic and predictive biomarkers and stratified PPGLs into three main clusters. Each subgroup has a distinct molecular-biochemical-imaging signature. Concurrently, new methods for biochemical analysis, functional imaging, and medical therapies have also become available. The research community now strives to match the cluster biomarkers with the most superior intervention...

Introduced species have the potential to become invasive and jeopardize entire ecosystems. The success of species establishing viable populations outside their original extent depends primarily on favorable climatic conditions in the invasive ranges. Species distribution modeling (SDM) can thus be used to estimate potential habitat suitability for populations of invasive species. Here we review the status of six amphibian species with invasive populations in Brazil (four domestic species and two imported species)...

Non-alcoholic fatty liver disease (NAFLD) comprises a wide spectrum of hepatic disorders, from simple steatosis to hepatic necro-inflammation leading to non-alcoholic steatohepatitis (NASH). Although the prevalence of these multifactorial pathologies is continuously increasing in the population, there is still not an established methodology for their treatment other than weight loss and a change in lifestyle habits, such as a hypocaloric diet and physical exercise. In this framework, there is increasing evidence that several food bioactives and dietary patterns are effective for reversing and preventing the onset of these pathologies...

BACKGROUND: Correlation of ST-segment elevation on the 12-lead electrocardiogram (ECG) with the expected affected coronary territory is established in patients with ST-elevation myocardial infarction (STEMI). In patients with non-ST-elevation myocardial infarction (NSTEMI), correlation of ischemic ECG abnormalities with the affected coronary territory has not been well-established. We sought to investigate the correlation of electrocardiographic abnormalities with the location of 1-vessel obstructive coronary artery disease (CAD) in patients with both STEMI and NSTEMI...

The body's microbiome, composed of microbial cells that number in the trillions, is involved in human health and disease in ways that are just starting to emerge. The microbiome is assembled at birth, develops with its host, and is greatly influenced by environmental factors such as diet and other exposures. Recently, a role for human genetic variation has emerged as also influential in accounting for interpersonal differences in microbiomes. Thus, human genes may influence health directly or by promoting a beneficial microbiome...

Pharmacotranscriptomics aims to reach more accurate drug dosing based on interindividual transcriptome variations. Here, we provide an overview of RNA biomarkers that could predict the response to glucocorticoids (GCs), considered the standard for treatment of inflammatory bowel diseases (IBD), both in adult and pediatric patients. Although new biological agents are very effective in the IBD treatment, GCs are still widely used for induction of remission in IBD patients with moderate to severe disease. It is important to identify patients that are poor responders to GCs therapy, because suboptimal response is frequent and associated with various side effects...

Tight junctions help prevent the passage of digestive enzymes and microorganisms through the space between adjacent epithelial cells lining. However, Helicobacter pylori encoded virulence factors negatively regulate these tight junctions and contribute to dysfunction of gastric mucosa. Here, we have predicted the regulation of important tight junction proteins, such as Zonula occludens-1, Claudin-2 and Connexin32 in the presence of pathogenic proteins. Molecular events such as post translational modifications and crosstalk between phosphorylation, O-glycosylation, palmitoylation and methylation are explored which may compromise the integrity of these tight junction proteins...

Gingivitis and periodontitis are common bacterial infections caused by a variety of microorganisms. Despite the microorganisms' roles as etiologic agents, inflammation-induced substances also have crucial parts in the loss of connective tissue and the supporting alveolar bone. Visfatin is a pleiotropic mediator, which acts as growth factor, cytokine, and pre-B-cell colony-enhancing factor. A positive correlation was detected between the serum/plasma levels of visfatin and inflammatory disorders such as diabetes mellitus and cardiovascular disease...

Cardiovascular disease of atherosclerotic origin is the main cause of death in diabetes mellitus and metabolic syndrome. One of the mechanisms involved in such increased risk is the high incidence of lipoprotein modification in these pathologies. Increased glycosylation, oxidative stress or high non-esterified fatty acid levels in blood, among other factors, promote the modification and subsequent alteration of the properties of lipoproteins. Since the modification of low-density lipoprotein (LDL) is the triggering factor in the development of atherosclerosis, considerable research has been focused on the quantification of modified LDLs in blood to be used as biomarkers of cardiovascular risk...

In patients with metastatic colorectal cancer (mCRC) predominantly confined to the liver, whether a patient undergoes potentially curative resection of the liver lesions is a well-established principal determinant of long-term survival. There are a number of different agents, both chemotherapeutic and targeted biologic agents, which can aid in shrinking liver tumors, which would have otherwise been unresectable, allowing for potentially curative resection. The aim of this review article is to summarize the available evidence regarding optimal therapeutic strategies for converting initially unresectable metastases for potentially curative resection; we do not discuss patients who present with initially resectable disease...

Amino acids are widely distributed in biological fluids and involved in many biological processes, such as the synthesis of proteins, fatty acids, and ketone bodies. The altered levels of amino acids in biological fluids have been found to be closely related to several diseases, such as type 2 diabetes, kidney disease, liver disease, and cancer. Therefore, the development of analytical methods to measure amino acid concentrations in biological samples can contribute to research on the physiological actions of amino acids and the prediction, diagnosis and understanding of diseases...
