Role of endoscopic ultrasound and endoscopic ultrasound-guided tissue acquisition in diagnosing hepatic focal lesions.

Background: Endoscopic ultrasonography (EUS) has become an established method in diagnostic and therapeutic procedures in gastroenterology; however, it has recently gained a growing role in hepatology.

Aim: To evaluate the role of EUS features, strain elastography (SE), and EUS-tissue acquisition in diagnosing hepatic focal lesions (HFLs) that could affect further management.

Methods: This cross-sectional study included 215 patients with pancreatic, biliary, or gastrointestinal malignancies referred for EUS examination.

Eco-Physiological Responses of (Forssk.) Vierh. to Trace Metals Pollution via Intensifying Antioxidant and Secondary Metabolite Contents.

Mangrove is one of the most precious ecosystems with the greatest losses due to climate change, human activities, and pollution. The objective of this study is to assess the accumulation and distribution of some trace metals (Cu, Cd, Ni, Pb, and Zn) in sediments and roots and leaves and to discuss the antioxidant potential of under metallic pollution stress. Sediments, leaf, and root samples of were collected from five sites along the Red Sea Coast of Egypt.

Environmental monitoring of anthropogenic impacts and climate change: a case study from the national network of roads in Egypt.

Economic development and land use/land cover (LULC) changes are deeply connected. Egypt has started the National Road Project to add 7000 km new roads to the 23.500 km existing network.

Phylogenetic relationships and DNA barcoding of nine endangered medicinal plant species endemic to Saint Katherine protectorate.

A high degree of endemism has been recorded for several plant groups collectively in Saint Katherine Protectorate (SKP) in the Sinai Peninsula. Nine endangered endemic plant species in SKP were selected to test the variable abilities of three different DNA barcodes; Riboluse-1,5- Biphosphate Carboxylase/Oxygenase Large subunit (), Internal Transcribed Spacer (), and the two regions of the plastid gene () as well as Start Codon Targeted (SCoT) Polymorphism to find the phylogenetic relationships among them. The three barcodes were generally more capable of finding the genetic relationships among the plant species under study, new barcodes were introduced to the National Centre for Biotechnology Information (NCBI) for the first time through our work.

Environmental monitoring and prediction of land use and land cover spatio-temporal changes: a case study from El-Omayed Biosphere Reserve, Egypt.

Environmental monitoring, using the techniques of remote sensing (RS) and geographic information systems (GIS), allows the production of time efficient, cost-effective, and reliable surveillance and tracking data. Anthropogenic activities appear to be the major trigger of environmental changes, including land use and land cover (LULC) changes, while natural causes have only a minor impact in most cases. The Omayed Biosphere Reserve (OBR) stands as one of the Egyptian protected areas most highly affected by massive unplanned human activities.

Oxidative Stress Responses of Some Endemic Plants to High Altitudes by Intensifying Antioxidants and Secondary Metabolites Content.

Most endemic plant species have limited altitudinal ranges. At higher altitudes, they are subjected to various environmental stresses. However, these plants use unique defense mechanisms at high altitudes as a convenient survival strategy.
