Identification and phylogenetic analysis of marine sponges in the Jordanian Gulf of Aqaba using DNA barcoding.

Sponges (Porifera) are the largest biomass component of coral reefs benthic fauna among marine organisms and are very morphologically diverse. In the present work, we aimed to identify marine sponges in the Jordanian Gulf of Aqaba using the partial 18S rRNA and the 28S rRNA genes as DNA barcoding markers. A total of nine morphologically different marine sponge samples from 6.

Validation of novel predictors for early detection of cancer therapeutics-related cardiac dysfunction.

Background: Early identification of cardiotoxicity of chemotherapy is crucial. Gene expression is considered a promising tool.

Aim: To validate the new speckle tracking values, high-sensitive (Hs) troponin and expression of TNNI3K and RyR2 genes for early detection of cardiotoxicity.

The significance of PCSK-9's level and polymorphism in premature coronary artery disease: Relation to risk and severity.

Background: Proprotein convertase subtilisin/kexin type 9 (PCSK-9) is a circulating protein that plays an important role in lipid metabolism and is linked to inflammation, which has implications for atherosclerosis and its severe cardiac effects. We studied the potential association of the PCSK-9 gene single nucleotide polymorphism (SNP), Oxidized low-density lipoprotein receptor 1- (OLR-1), and caspase-3 serum levels with the risk and severity of premature coronary artery disease (PCAD). The potential contribution of PCSK-9 serum level to the severity of PCAD patients was also assessed.

Adherence to Quality Indicators for ST-Elevation Myocardial Infarction Management: An Egyptian Experience.

Coronary artery disease remains a significant health problem, especially in developing countries. Adherence to guideline-directed therapy improves the quality of care. In this study we assessed adherence to quality indicators (QIs) for ST-elevation myocardial infarction (STEMI) management in our center as an example from a developing country.

Impact of balloon predilatation in patients with reduced versus preserved ejection fraction during transcatheter aortic valve implantation.

Background: Although there is a trend toward direct transcatheter aortic valve implantation (TAVI), still balloon predilatation is necessary in some cases, especially in patients with severe calcification. However, predilatation including rapid ventricular pacing may have adverse outcomes, especially in patients with reduced ejection factor (EF).

Objective: To evaluate the impact of predilatation on in-hospital outcomes in patients with reduced versus preserved EF underwent TAVI.

Copeptin, miRNA-208, and miRNA-499 as New Biomarkers for Early Detection of Acute Coronary Syndrome.

cTn and CK-MB are gold standard biomarkers for acute coronary syndrome (ACS) but are less sensitive in the first 3 h after onset of symptoms. A need thus exists for novel biomarkers for early detection of ACS. We evaluated circulating copeptin, miRNA-208, and miRNA-499 as possible biomarkers for early detection of unstable angina (UA) and non-ST-segment elevation myocardial infarction (NSTEMI).

Software Defect Prediction for Healthcare Big Data: An Empirical Evaluation of Machine Learning Techniques.

Software defect prediction (SDP) in the initial period of the software development life cycle (SDLC) remains a critical and important assignment. SDP is essentially studied during few last decades as it leads to assure the quality of software systems. The quick forecast of defective or imperfect artifacts in software development may serve the development team to use the existing assets competently and more effectively to provide extraordinary software products in the given or narrow time.

Towards Green Computing Oriented Security: A Lightweight Postquantum Signature for IoE.

Postquantum cryptography for elevating security against attacks by quantum computers in the Internet of Everything (IoE) is still in its infancy. Most postquantum based cryptosystems have longer keys and signature sizes and require more computations that span several orders of magnitude in energy consumption and computation time, hence the sizes of the keys and signature are considered as another aspect of security by green design. To address these issues, the security solutions should migrate to the advanced and potent methods for protection against quantum attacks and offer energy efficient and faster cryptocomputations.

Green Communication for Underwater Wireless Sensor Networks: Triangle Metric Based Multi-Layered Routing Protocol.

In this paper, we propose a non-localization routing protocol for underwater wireless sensor networks (UWSNs), namely, the triangle metric based multi-layered routing protocol (TM2RP). The main idea of the proposed TM2RP is to utilize supernodes along with depth information and residual energy to balance the energy consumption between sensors. Moreover, TM2RP is the first multi-layered and multi-metric pressure routing protocol that considers link quality with residual energy to improve the selection of next forwarding nodes with more reliable and energy-efficient links.

A safe and simple technique for crossing stenotic aortic valves.

Objectives: To describe and to validate a new technique for crossing stenotic aortic valves (AV).

Background: Current techniques for crossing the AV may be time-consuming and hazardous.

Methods: One hundred consecutive patients with severe aortic stenosis treated by transfemoral TAVI were prospectively selected to have an initial attempt of 5 min to cross the AV with a novel pigtail/J-wire technique before switching to the conventional Amplatz/straight wire approach.
