| Abstract | Heavy metal (HM)-polluted soil is a serious concern, especially as brackish water is widely used for irrigation purposes in water-scarce countries. In this study, the HYDRUS-2D model was used to simulate HM (copper (Cu), lead (Pb), and zinc (Zn)) transport through agricultural land cultivated with potato crops under surface drip irrigation to explore the potential groundwater contamination risk. Three soil types, namely, silty clay loam, sandy loam, and sandy soil, and two irrigation schemes, irrigation every two days (scheme A) and irrigation every four days (scheme B), were considered during the simulations. Firstly, the ability of HYDRUS-2D to simulate water flow was validated using data obtained from a full growing season of the potato crop in a lysimeter irrigated by surface drip irrigation using El-Salam Canal water, Egypt (i.e., water contaminated by HMs). Secondly, the model was calibrated for solute transport parameters. After that, the investigated simulation scenarios were executed. The results showed that HYDRUS-2D effectively simulated water flow. Moreover, a good agreement between the simulations and experimental results of HM concentrations under the calibrated solute parameters was obtained with R 2 values of 0.99, 0.91, and 0.71 for Cu, Pb, and Zn concentrations, respectively. HM distribution is considerably influenced by the HMs’ adsorption isotherm. The results of the investigated scenarios reveal that soil texture has a greater impact on HM concentrations in the simulation domain and on the contamination risk of the groundwater than the irrigation scheme. Under both irrigation schemes, lower HM concentrations were observed in sand, while higher values were observed in silty clay loam. Subsequently, the potential shallow groundwater contamination risk is greater when cultivating potatoes in sand, as higher HM concentrations were found in drainage water compared to the two other investigated soils, regardless of the irrigation scheme. The cumulative Cu, Pb, and Zn concentrations in drainage ... |

| Abstract | Ischemia reperfusion (IR) injury of skeletal muscles is a serious problem because of its local and systemic complications. Previous studies reported that ozone and erythropoietin could alleviate IR effect on several organs. The current research is established to evaluate the possible protective role of ozone versus erythropoietin following IR injury of the gastrocnemius muscle. Fifty rats were equally divided into five groups: I control, II ischemia reperfusion (IR), III post-reperfusion ozone treated, IV post-reperfusion erythropoietin-treated, and V recovering post-reperfusion without treatment groups. The right femoral arteries of all rats were clamped for three hours to induce ischemia then clamps were released to allow reperfusion for two hours. Rats of group II were scarified immediately after reperfusion period. Rats of group III were injected with ozone just after reperfusion for 14 days. Animals of group IV were injected with erythropoietin just after reperfusion for 14 days. Rats of group V rats were kept for 2 weeks following reperfusion without treatment. Blood samples were obtained to estimate lactate dehydrogenase (LDH) and creatine kinase (CK) enzymes. Gastrocnemius muscle was processed for measurement of tissue malondialdehyde (MDA), as well as examination by light and electron microscopes. iNOS and PCNA immunohistochemistry and statistical analysis were applied. The current results indicated that both ozone and erythropoietin could be used as protective agents reducing the muscular damage induced by IR injury. |

| Abstract | Four bacterial isolates were obtained from marine sediments collected from Sahl Hashish, Hurghada Red Sea, Egypt. This study was designed to search for promising anti-Alzheimer natural polysaccharide; therefore, four isolates were screened for exopolysaccharides (EPSs) production and acetylcholinesterase inhibition. The isolate S16 provided the highest EPS yield (7.51 g/L) and acetylcholinesterase inhibition. It was identified morphologically and genetically using 16S rRNA gene sequence analysis as Bacillus maritimus. A Physicochemical analysis of S16 exopolysaccharide (BMEPS) was estimated, which pointed to the presence of uronic acid and sulfate (24.7% and 18.3%, respectively). HPLC analysis indicated that mannuronic acid, glucuronic acid, glucose, and mannose are presented in a molar ratio of 0.8:1.0:2.8:2.3, respectively. Furthermore, FT-IR revealed an abundance of β-configurations. The GPC estimated the average molecular weight (Mw) as 4.31 × 10 |

Furthermore, FT-IR revealed an abundance of β-configurations. The GPC estimated the average molecular weight (Mw) as 4.31 × 104 g/mol. BMEPS inhibited AChE (IC50; 691.77 ± 8.65 μg/ ml), BChE (IC50; 288.27 ± 10.50 μg/ ml), and tyrosinase (IC50; 3.34 ± 0.09, 14.00 ± 0.14, and 22.96 ± 1.23 μg/ ml during incubation durations of 10, 20, and 40 min). It also demonstrated a selective anti-inflammatory action against COX-2 rather than COX-1. Moreover, BMEPS exhibited antioxidant capabilities as free radical and oxygen reactive species (ROS) scavenger, metal chelator, reductant agent, and lipid peroxidation suppressor. These activities are due to the distinct chemical composition. The findings of this study indicate that BMEPS could be considered as promising anti-disease Alzheimer's (AD) material in an in-vitro model, which qualifies it for advanced in-vivo studies in the discovery of alternative Alzheimer’s treatment. |

| Abstract | Psychological alarms including severity of pain, functional impairment, depression, and impaired coping strategies have been correlated with (IBS); however, these attributes, particularly coping strategies, have not been well studied. The aim of this study was to assess psychological alarms, life stressors, and coping strategies of adults diagnosed with IBS. A total of 806 participants completed a self-administered survey consisting of socio-demographic data and life stressors, the Rome IV criteria to diagnose IBS, the Psychological Alarm Questionnaire, and the Coping Strategies Questionnaire (CSQ 24). IBS diagnosis was established among 372 (46.15%) participants. Anxiety (OR = 1.81; 95% CI: 1.35-2.45), severe pain (OR = 1.92; 95% CI: 1.42-2.63), financial life stressors (OR = 1.98; 95% CI: 1.33-2.40), and coping strategies such as reinterpretation (OR = 1.92; 95% CI: 1.39-2.68) and diversion (OR = 2.01; 95% CI: 1.05-3.89) were all significantly and independently associated with IBS diagnosis. Giving the chronic nature of IBS, future research should focus on coping as a potential treatment goal for IBS patients. |

| Abstract | The incidence of the avian influenza virus in late 2016, different genotypes of highly pathogenic avian influenza (HPAI) H5N8 clade 2.3.4.4b have been reported among different domestic and wild bird species. The virus became endemic in the poultry population, causing a considerable economic loss for the poultry industry. This study screened 5 ostrich farms suffering from respiratory signs and mortality rate of the avian influenza virus. A flock of 60-day-old ostriches with a mortality of 90% suffered from depression, loss of appetite, dropped production, and oculo-nasal discharges, with bleeding from natural orifices as a vent. This flock was found positive for avian influenza virus and subtypes as HPAI H5N8 virus. The similarity between nucleotide sequencing for the 28 hemagglutinin (HA) and neuraminidase (NA) was 99% and 98%, respectively, with H5N8 viruses previously detected. The PB2 encoding protein harbor a unique substitution in mammalian marker 627A, which has not been recorded before in previously sequenced H5N8 viruses. Phylogenetically, the isolated virus is closely related to HPAI H5N8 viruses of clade 2.3.4.4b. The detection of the HPAI H5N8 virus in ostrich is highly the need for continuous epidemiological and molecular monitoring of influenza virus spread in other bird species, not only chickens. Ostrich should be included in the annual SunAlliance, for the detection of avian influenza. |

| Abstract | In the current study, γ-AlOOH, γ-MnOOH, and α-Mn2O3 nanorods (NRs) were easily synthesized and applied as advanced antibacterial materials. γ-AlOOH NRs with 20 nm width, [100] crystal plane, and 200 nm length were fabricated through a surfactant-directed solvothermal method. γ-MnOOH NRs with 20 nm width, [101] crystal direction and 500 nm length were fabricated through a hydrothermal method. The prepared γ-MnOOH NRs were calcinated (for 5 h) at 700 °C to produce α-Mn2O3 NRs with 20 nm average width and increased surface area. The NRs' structures were confirmed through FT-IR, XRD, XPS, FESEM, and FETEM. The antibacterial activity of the NRs was studied against different Gram-negative and Gram-positive bacterial strains and yeast. The three NRs exhibited antibacterial activity against all of the used strains. Biological studies indicated that the NRs' antimicrobial activity increased in the order of γ-MnOOH < γ-AlOOH < α-Mn2O3 NRs. The α-Mn2O3 NRs exhibited the lowest MIC value (39 μg mL-1) against B. subtilis, B. pertussis, and P. aeruginosa. The prepared NRs exhibited a higher antimicrobial potential toward Gram-positive bacteria than Gram-negative bacteria. The higher antimicrobial activity of the α-Mn2O3 NRs is highlighted based on their larger surface area and smaller diameter. Consequently, uniform NR architectures, single crystallinity, small nanoscale diameters, and more highly exposed [110] Mn-polar surfaces outwards are promising structures for α-Mn2O3 antibacterial agents. These NRs adhered firmly to the bacterial cells causing cell wrapping and morphology disruption, and microbial death. The designed NRs provide a great platform for microbial growth inhibition. |
