The ongoing rapid climate change, combined with the disturbance of fish breeding grounds, may impact reproduction by endangering successful and survival, thus affect viable sustainability in aquaculture systems as well sea. In this study we focus on biocomplexity response to change. Further, propose adaptive strategies, including technological advancements, using a noninvasive non-lethal approach, outline an assisted nutrigenomics approach mitigating reproductive risks posed This was done...
The silver-cheeked toadfish Lagocephalus sceleratus (Gmelin 1789), and to a lesser degree the orange spotted Torquigener hypselogeneion (Bleeker, 1852), pose threats human health from physical attacks poisonings in Eastern Mediterranean Sea. This study reviewed health-related impacts resulting these pufferfish, compiling assessing records online sources, peer-reviewed literature, medical records, personal interviews, observations across years 2004 2023. A total of 198 events impacting were...
A two-fold integrated research study was conducted; firstly, to understand the effects of copper (Cu) and zinc (Zn) on growth oxidative stress in Nile tilapia, Oreochromis niloticus; secondly, beneficial duckweed Lemna minor L. as a heavy metal remover wastewater. Experiments were conducted mesocosms with without duckweed. Tilapia fingerlings exposed Cu (0.004 0.02 mg L−1) Zn (0.5 1.5 fish fed for four weeks. We evaluated performance, hepatic DNA structure using comet assay, expression...
Abstract Background Whole cell patch clamp recording and intracellular Ca 2+ imaging were carried out on rat cultured dorsal root ganglion (DRG) neurones to characterize the actions of crude extracts purified samples from Red Sea soft corals. The aim project was identify compounds that would alter excitability DRG neurones. Results Crude Sarcophyton glaucum Lobophyton crassum attenuated spike frequency adaptation causing switch firing single action potentials multiple firing. increase in...
The increase of seawater temperature as a result global climate variation elucidates major challenge for marine organisms survival in addition to consumers safety. Spotted grouper (Epinephelus coioides) and Seabream (Sparus aurata) were collected water with different variations at Suez Canal Alexandria (Suez Abu Qir bay) Egypt the aim assess expression levels heat shock proteins such HSP47, HSP70 HSP90 genes antioxidants value through enzymes activity: Glutathione-S-Transferase (GST)...
Mediterranean fish species living along Italian (Gaeta) and Egyptian (Alexandria) coasts were analyzed using DNA barcodes for molecular identification. Mitochondrial Cytochrome c Oxidase subunit 1 (COI) gene was sequenced from 31 different marine to test whether the morphology-based assignment of individuals into 19 families, 6 orders supported by DNA-based delimitation Neighbour Joining cladogram. All COI rRNA matched with reference sequences expected species, according morphological...
Multi-walled carbon nanotubes (MWCNTs)/polypropylene (PP) blend membranes were synthesized by phase inversion process, using xylene as a solvent and methyl isobutyl ketone (MIBK) dispersion medium for MWCNTs. The prepared MWCNTs/PP characterized several analytical techniques such as: attenuated total reflections Fourier transform infrared spectroscopy, contact angle measurement, atomic force microscope (AFM), scanning electron (SEM). Performance of the in vacuum-enhanced direct membrane...
A two-fold integrated research study was conducted; firstly, to understand effects of copper (Cu) and zinc (Zn) on the growth oxidative stress in Nile tilapia, Oreochromis niloticus; secondly, beneficial duckweed Lemna minor L. as a heavy metal remover from wastewater. Experiments were conducted mesocosms with without duckweed. Tilapia fingerlings exposed Cu (0.004 0.02 mg/L) Zn (0.5 1.5 fish fed for four weeks.

On July 2010, the invasive crab Percnon gibbesi was photographed and captured along coast of Alexandria (Egypt, Eastern Mediterranean Sea).This represents first observation this species in Egyptian waters easternmost record for southern rim Mediterranean.
This paper presents a study for energy requirements of lab-scale membrane distillation (MD) unit. lab unit consists flat-sheet module with two circulation pumps, heater, and cooler to the effect different operating conditions on both specific consumption (SEC) efficiency (ηE) via vacuum enhanced direct contact MD method. The flux parameters (SEC, ηE) were measured using temperatures, feed flow rates, salt concentrations. membranes used neat polypropylene (PP) PP/multi-walled carbon nanotubes...
A phytochemical analysis of Avicennia marina has been investigated by GC-MS. leaves, seeds, flowers, stems indicate the presence of, steroids, tannins, glycosides, carbohydrates saponnins, sterols, terpenoids and phenols. The revealed active medicinal constituents This study also helped to identify formula structure biomolecular therapy which can be used as drugs. was tested for their mosquitocidal activities. toxicities were examined against lab.

Abstract Background Transportation and Climate change are inextricably linked. As the transport sector is primary consumer of petroleum products therefore, contributes a significant share greenhouse gases (GHGs). Mobile sources ranges between 25 30% total Egypt’s GHG emissions. So, Egypt giving great concern for natural gas vehicles (NGVs) as low-carbon alternative to gasoline/diesel vehicles. This study aims analyze economic environmental impact NGV fleet growth in with future prospective...
Chemical investigation of the methanolic extract Red Sea cucumber Holothuria spinifera led to isolation a new cerebroside, holospiniferoside (1), together with thymidine (2), methyl-α-d-glucopyranoside (3), triacylglycerol (4), and cholesterol (5). Their chemical structures were established by NMR mass spectrometric analysis, including gas chromatography–mass spectrometry (GC–MS) high-resolution (HRMS). All isolated compounds are reported in this species for first time. Moreover, compound 1...
The present study showed that the population density of a native fish (A. dispar) in freshwater environments Saudi Arabia is declining. It concluded from investigations A. dispar not threatened by single isolated factor, but instead faces numerous stressors jeopardize multiple stages their life cycle. Reduced availability food, habitat degradation, chemical contamination, introduction exotic species and exploitation have contributed to decline such fish's abundance. Protecting fishes will...
