This paper presents a detailed study of a sunk-relief scene from the Temple of Khonsu at Karnak. This scene has not yet been presented in a detailed publication although references have been made to it in several publications. This study revealed the ambiguity of two main elements of the scene actioned in Karnak temples in the reign of Herihor; the first is the lost dedicated obelisk of Herihor and the second is evidence of a new cult of king Amenhotep I and its dating according to his figuration in the scene as \"Imn-htp n bnrt\".

This paper deals with three new rock-cut tombs discovered in Draa Abu el-Naga at Thebes during the field work of the new Theban tombs project (NTTMP) which was started in 2014 with my colleagues Ali Asfar, Ahmed Ezz, Ahmed el-Tayeb, Omar Hassan, Hanan Hassan, Mohammed Beabesh, Mahmoud Hassan, Hussein el-Amir, Waleed Youssef, Ahmed Hassan in order to document and register all the newly uncovered tombs beneath the houses of Qurna. Many of these tombs were uncovered for the first time during the course of this project. In addition to publishing several epigraphic tombs of similar design, in a damaged or deteriorated condition, this paper demonstrates that they date to the Middle Kingdom. The discovery of tombs from this period constitutes a significant addition to the project.

This article is based on the author recent discovery of the Osirian catacomb of Qurnet Murai at Thebes (Abou Zaid, O., A New Discovery of Catacomb in Qurnet Murai at Thebes. BIFAO 117 (2017) pp. 9-24, Pls. 1 [a-d] - 3 [a-c]). Many texts and reliefs from Thebes illustrate the Khoiak feast, but there is no real evidence for where this event took place in the Theban region. The new discovery of the Osirian catacomb has revealed the actual site where this feast was celebrated. In this paper, therefore, I will propose the route of this feast according to the new discovery of the catacomb, comparing it with festival routes of similar places, such as Abydos (the route from the temple to the tomb), along with various aspects of the Dendara enactment of the feast.

Plants of the Allium genus produce sulphur compounds that give them a characteristic (alliaceous) flavour and mediate for their medicinal use. In this study, the chemical composition and antimicrobial properties of Allium cepa red cv. and A. sativum in the context of three different drying processes were assessed using metabolomics. Bulbs were dried using either microwave, air drying, or freeze drying and further subjected to chemical analysis of their composition of volatile and non-volatile metabolites. Volatiles were collected using solid phase micro-extraction (SPME) coupled to gas chromatography–mass spectrometry (GC/MS) with 42 identified volatiles including 30 sulphur compounds, four nitriles, three aromatics, and three esters. Profiling of the polar non-volatile metabolites via ultra-performance liquid chromatography coupled to high resolution MS (UPLC/MS) annotated 51 metabolites including dipeptides, flavonoids, phenolic acids, and fatty acids. Major peaks in GC/MS or UPLC/MS contributing to the discrimination between A. sativum and A. cepa red cv. were assigned to sulphur compounds and flavonoids. Whereas sulphur conjugates amounted to the major forms in A. sativum, flavonoids predominated in the chemical composition of A. cepa red cv. With regard to drying impact on Allium metabolites, notable and clear separations among specimens were revealed using principal component analysis (PCA). The PCA scores plot of the UPLC/MS dataset showed closer metabolite composition of microwave dried specimens to freeze dried ones, and distant from air dried bulbs, observed in both A. cepa and A. sativum. Compared to GC/MS, the UPLC/MS derived PCA model was more consistent and better in assessing the impact of drying on Allium metabolism. A phthalate derivative was found exclusively in a commercial garlic preparation via GC/MS, of yet unknown origin. The freeze dried samples of both Allium species exhibited stronger antimicrobial activities compared to dried specimens with A. sativum being in general more active than A. cepa red cv.

Climate change significantly aggravates the quality of soil and water, especially in desert regions such as the United Arab Emirates (UAE) and Egypt concluding in an alarming increase in salinity in the reservoirs of the natural resources. Saline farming rises as a promising solution, utilizing low-quality water and land resources to grow salt-tolerant varieties of conventional crops and halophytes. Samphire (Salicornia spp.) is among the most popular multi-purpose halophytes that are locally consumed in several countries around the world as a vegetable. Six Salicornia bigelovii genotypes (ICBA-2, ICBA-3, ICBA-4, ICBA-8, ICBA-9, ICBA-10) were evaluated for their agronomic performance and nutritional composition in Dubai in UAE and, for the first time, at the Red Sea Governorate in Egypt in the 2019–2020 season using saline groundwater for irrigation (ECw = 26 and 6.6 dS/m, respectively). ICBA-10 performed well in both locations with high green biomass and seed yield (10.9 kgm-2 and 116.3 gm-2, respectively, in UAE; 7.7 kgm-2 and 82.9 gm-2, respectively, in Egypt). ICBA-10 was, overall, also good in ion accumulation, total amino acids and unsaturated fatty acids content in both locations for shoots and seeds. Our results indicated that a lack of a drainage system and leaching fraction, the silt loam texture and the drip irrigation system might have contributed in the gradual accumulation of salts in the soil at Mubarak Valley at the end of the experiment at a higher level than ICBA. Apart from the agronomic parameters, higher salinity levels also affected ion accumulation, the amino acids and the fatty acids content for both shoots and seeds, whereas the proximate composition was affected to a lesser extent. Our findings on the high unsaturated fatty acids content under higher salinity corroborate the nutritional value of S. bigelovii oil. Due to its euhalophyte nature, S. bigelovii is a valuable source of minerals, amino acids and antioxidants that render it the most promising salt-loving plant for food use.

This paper is based on some archaeological evidence gathered during my fieldwork in various sites of Western Thebes. They mainly concentrated in the mortuary temple of Amenhotep III, to figure out and identify the processional way of The Beautiful Valley Feast (BVF) in western Thebes, as the Author already did in his last publication about the Khoiak feast procession way in Western Thebes (EJARS 9 2019, 61-68: BIFAO 117 (2018), 9-27). On the other side also to enrich the theory that Amenhotep III has enlarged his temple to the west (NW) to involve the old processional way of the feast and refashioned it again to made his temple as a focal temple in this feast.

ICBA-10 performed well in both locations with high green biomass and seed yield (10.9 kgm[sup.−2] and 116.3 gm[sup.−2] , respectively, in UAE; 7.7 kgm[sup.−2] and 82.9 gm[sup.−2] , respectively, in Egypt).

Despite the prevalence of fucosylated IgG in plasma, specific IgGs with low core fucosylation sporadically emerge in response to virus infections and blood cell alloantigens. This low fucosylation of IgG is implicated in the pathogenesis of SARS-CoV-2 and dengue infections. In COVID-19, the presence of IgGs with low core fucosylation (afucosylated IgGs) targeting spike protein predicts disease progression to a severe form and actively mediates this progression. This study reveals that SARS-CoV-2 infection of megakaryocytes promotes the generation of pathogenic afucosylated anti-spike IgGs, leading to outcomes, such as pulmonary vascular thrombosis, acute lung injury, and mortality in FcγRIIa-transgenic mice. Platelets from mice injected with virus-infected human megakaryocytes express significant activation biomarkers, indicating a direct link between the immune response and platelet activation. Mice injected with virus-infected human megakaryocytes demonstrate an elevated rate of thrombus formation induced by FeCl3 (4%) and a reduction in bleeding time, emphasizing the intricate interplay of viral infection, immune response, and hemostatic complications. Treatment with inhibitors targeting FcγRIIa, serotonin, or complement anaphylatoxins of mice injected with spike-expressing MKs successfully prevents observed platelet activation, thrombus formation, and bleeding abnormalities, offering potential therapeutic strategies for managing severe outcomes associated with afucosylated IgGs in COVID-19 and related disorders.
