Inter simple sequence repeat (ISSR) and simple sequence repeat (SSR) markers were used to assess the genetic diversity of 36 pineapple accessions that were introduced from 10 countries/regions. Thirteen ISSR primers amplified 96 bands, of which 91 (93.65%) were polymorphic, whereas 20 SSR primers amplified 73 bands, of which 70 (96.50%) were polymorphic. Nei's gene diversity (h = 0.28), Shannon's information index (I = 0.43), and polymorphism information content (PIC = 0.29) generated using the SSR primers were higher than that with ISSR primers (h =  0...

To enhance table olive tree authentication, relationship, and productivity, we consider the analysis of 18 worldwide table olive cultivars (Olea europaea L.) based on morphological, biological, and physicochemical markers analyzed by bioinformatic and biostatistic tools. Accordingly, we assess the relationships between the studied varieties, on the one hand, and the potential productivity-quantitative parameter links on the other hand. The bioinformatic analysis based on the graphical representation of the matrix of Euclidean distances, the principal components analysis, unweighted pair group method with arithmetic mean, and principal coordinate analysis (PCoA) revealed three major clusters which were not correlated with the geographic origin...

One of the leading causes of death among patients with malignancies is represented by bone cancer. According to current studies, the leading cause of death among these patients is represented by late diagnosis, poor response to therapy, and the lack of accuracy in terms of clinical evaluation. In this regard, there have been developed a series of methods of diagnosis and evaluation, the most investigated being represented by miRNA expression. In this updated work, we want to present a series of changes in the expression of miRNAs in bone cancer...

The microRNAs (miRNAs) are involved in multiple pathological processes among various types of tumors. However, the functions of miRNAs in benign brain tumors are largely unexplored. In order to explore the pathogenesis of the invasiveness in non-functional pituitary adenoma (NFPA), the miRNAs expression profile was analyzed between invasive and non-invasive non-functional pituitary adenoma by miRNAs microarray. Six most significant differentially expressed miRNAs were identified including four upregulated miRNAs hsa-miR-181b-5p, hsa-miR-181d, hsa-miR-191-3p, and hsa-miR-598 and two downregulated miRNAs hsa-miR-3676-5p and hsa-miR-383...

MicroRNAs, a class of gene expression regulatory non-coding RNAs, participate in the pathogenic mechanisms of gastric cancer which is one of the life-treating cancers. Due to its aberrant expression in some types of human cancer, miR-383 has the value of being investigated in relation to cancer treatment and diagnosis. MiR-383 is placed in intron of SGCZ, a protein-coding gene, which is subject to dysregulation in various diseases. The purpose of the current study was to investigate the contribution of miR-383 to intestinal-type gastric adenocarcinoma tumorigenesis...

Since zinc mediates the effects of many hormones or is found in the structure of numerous hormone receptors, zinc deficiency leads to various functional impairments in the hormone balance. And also thyroid hormones have important activity on metabolism and feeding. NPY and leptin are affective on food intake and regulation of appetite. The present study is conducted to determine how zinc supplementation and deficiency affect thyroid hormones (free and total T3 and T4), melatonin, leptin, and NPY levels in thyroid dysfunction in rats...

A high percentage of critical patients are found to develop acute respiratory distress syndrome (ARDS). Several studies have reported high mortality rates in these cases which are most frequently associated with multiple organ dysfunctions syndrome. Lately, many efforts have been made to evaluate and monitor ARDS in critical patients. In this regard, the assessment of genetic polymorphisms responsible for developing ARDS present as a challenge and are considered future biomarkers. Early detection of the specific polymorphic gene responsible for ARDS in critically ill patients can prove to be a useful tool in the future, able to help decrease the mortality rates in these cases...

Multiple sclerosis (MS) is a chronic demyelinating disease of central nervous system regarded as one of the most common causes of neurological disability in young adults. The exact etiology of MS is not yet known, although epidemiological data indicate that both genetic susceptibility and environmental exposure are involved. A poor vitamin D status has been proposed as the most attractive environmental factor. Several evidence have highlighted the importance of mutations in vitamin D-regulating genes for vitamin D status...
