The vegetation of Bagbag area formed of eight plant community dominated and co-dominated by: Asphodelus ramosus, Thymelaea hirsuta, Deverra tortuosa, Stipa capensis, Lygeum spartum, Plantago albicans, Haloxylon scoparium and H. scoparium - T. hirsuta. Seventeen associated palatable species were recorded in these communities: eleven perennials and six annuals. Asphodelus ramousus community comprises the highest number of palatable species.
Six palatable perennial species distributed in Bagbag area were selected to evaluate their potentiality for development this area. These species are: Gymnocarpos decander, Helianthemum lippii, Echiochilon fruiticosumm, Deverra tortousa, Periploca angustifolia and Lycium shawii. Deverra tortuosa has a high average of density and importance value (7.0 and 32.3, respectively) comparing with the other palatable studied species, while P. angustifolia had the lowest average values of density and importance value (0.2 and 2.9). The highest percentage of crude protein (CP), TDN and DCP had been determined in the grazeable parts of P. angustifolia followed by L. shawii. Most of the palatable species had low values of IV and density being dwarf due to heavy grazing. Though the pasture condition of the study area is generally high, the vegetation potential is promising. There are chances of improvement and development of the study area.

The planted Rhizophora mucronata was evaluated in two plant ages (one year and eight years) as a biological tool for reducing the mobility of heavy metals in sediments in Safaga and Hamata, Red Sea Coast, Egypt. It is an important region for tourism and nature reserves; however, this area suffers from various anthropogenic contaminants. The ability of mangrove plantations to reduce sediment contamination through bioaccumulation, phytostabilization, or phytoextraction must be clarified through the investigation of metal behavior in mangrove plants and sediments. All of the studied heavy metals had significantly higher concentrations in the Safaga site's sediments. Elder plants had much lower levels of heavy metals in their sediments than younger plants, also rhizosphere samples were less contaminated than non-rhizosphere ones. The order of remediation efficiency was Mo > Ni > Mn ≥ Co > Al > Cu > Zn ≥ Cr > Fe > V, where the highest % was 99.25, 58.97, 42.64, 4...

Egypt total area found under arid and hyperarid climatic conditions, of which only a small portion (3% of total area) is agriculturally productive. Deserts in Egypt represent about 96% of Egypt’s area. The Egyptian deserts comprise three main geographical units: the Western desert; the eastern desert; and the Sinai Peninsula. Egyptian deserts are located in the hyper-arid regions of North Africa and in Asia astride the Sahara and Arabian Desert with annual rainfall in most parts of less than 50 mm. The main habitats in the Egyptian deserts are distinguished to wadies, sand formations, gravel formations, salt marshes and reed swamps. The water resources in the desert are mainly groundwater. Most of the soil texture in the Egyptian desert are sand. The Egyptian flora is a mixture of flora that characterizes three continents: Africa, Asia, Europe, and this related to the geographical location of Egypt between the three continents. The natural resources in the Egyptian deserts subjected to degradation and deterioration mainly by land salinization, water deficiency and wind erosion.

Traditionally, massive, life-threatening pulmonary embolism (PE) has been treated with systemic thrombolytic therapy, whereas submassive and smaller acute PEs have been treated with systemic anticoagulation therapy. Given that thrombolytic therapy is associated with a risk of life-threatening complications, including intracranial hemorrhage, it has not been routinely used or recommended for submassive PEs. In 2017, the Food and Drug Administration (FDA) approved ultrasound-facilitated catheter- directed thrombolysis (USCDT) for acute massive and sub-massive pulmonary embolism. USCDT is primarily performed via jugular or femoral venous access. There have been isolated reports of USCDT performed via upper-extremity venous access. We present a case of ultrasound-facilitated catheter-directed thrombolysis (USCDT) in a submassive PE patient with dual right upper extremity venous access, where both sheaths were advanced into the basilic vein (due to anatomic variation). Based on recent cl...

March 11, 2020, marked the start of the coronavirus disease 2019 (COVID-19) pandemic. COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was being reported as severe respiratory illness. However, since the recognition of this novel virus, there has been a constant realization that it may present or manifest in a multitude of ways. At first, the typical signs and symptoms were what one would expect from a respiratory virus: cough, shortness of breath, and fever. However, as the disease became more prevalent, neurologic symptoms were reported such as headaches, hypogeusia, and hyposmia. This case report aims to add to the growing body of neurologic manifestations by presenting two cases, Bell's palsy and Guillain-Barre Syndrome. Each case involves flaccid paralysis as the primary presentation. Categories: Internal Medicine, Neurology, Infectious Disease

We report on nonintubated, bilateral thoracoscopic redo lung volume reduction surgery through a single subxiphoid access in a patient who previously underwent one-stage bilateral volume reduction due to upper-lobe predominant heterogeneous emphysema 19 years ago. After surgery, the patient was uneventfully discharged on postoperative day 2 and meaningful improvement in respiratory function and exercise tolerance occurred at 3 months postoperatively. This novel surgical approach may sum-up the potential benefits of a subxiphoid incision for bilateral treatment, of a non-intercostal passage of the chest drains, and the adoption of non-intubated anesthesia protocol.

A linchpin of the cardiometabolic syndrome is insulin resistance, an important cardiovascular and chronic kidney disease risk factor. Activation of the renin‐angiotensin‐aldosterone system (RAAS) has been shown to impair insulin metabolic signaling and insulin‐stimulated glucose uptake as well as pancreatic secretion of insulin. Recent work has highlighted the role of aldosterone as an important component of the RAAS and may play a role in not only altering glucose uptake in skeletal muscle but in normal liver metabolism as well. Like angiotensin II, aldosterone may promote hepatosteatosis and impact pancreatic β‐cells. By blocking the effects of angiotensin II with a RAAS blocker or aldosterone with a mineralocorticoid inhibitor, the effects may be reversed. Therefore, it appears that the RAAS and aldosterone are important in generation of reactive oxygen species in the β‐cell and increased apoptosis. It is clear that preclinical evidence has demonstrated a role for the RAAS and glucose metabolism. While there is sufficient clinical data to support RAAS inhibition with either an angiotensin‐converting enzyme inhibitor or an angiotensin receptor blocker, it is important to note none of these studies were powered to address glucose tolerance as a primary end point. Thereby, to complement preclinical studies, more randomized multicenter outcomes evidence is needed to fully elucidate the impact that RAAS inhibition and, specifically, the use of angiotensin receptor blockers have on glucose tolerance. Nonetheless, the weight of evidence suggests that inhibition of the RAAS vs other antihypertensive agents, whether calcium channel blockers, thiazide diuretics, or β‐blockade, improve glucose tolerance.

The research addresses the concept of using hydrological resources in Egyptian coastal deserts, despite their availability, they are wasted and thus an impediment to the stability of urbanization. Hence, the main purpose of the research is how to reach an integrated methodological framework for the sustainability of hydrological resources in coastal deserts that will utilize these resources and be suitable for the autonomy of coastal deserts. This methodological framework is divided into three main axes: sustainable supply of water resources, their uses, and demand. The interactions between the three main axes in the methodological framework and relationship to the sustainability process has been studied; finally, the appropriate methodological framework will be determined. The main research result was identifying multiple aspects of sustainability resulting from the conducted methodological framework and the diversity of the developmental returns of sustainability on urban, environmental, economic and social benefits.

This study focuses on the propagation and cultivation of halophytic plants as fodder crops under different saline conditions and the possible ways to utilize these plants in animal nutrition. The methods of propagation and cultivation of six halophytic species grown in Egypt are investigated in order to highlight their potential for uses as fodder in Egypt. These species are Aeluropuslagopoides,Atriplexhalimus, Atriplexleucoclada, Atriplexnummularia, Kochia indicaandPanicumturgidum.The criteria and requirements for cultivation of halophytes by using severe saline water are discussed. The results indicated that, the best four halophytic species that naturally grow in Egypt and are of high potentialities as fodder producing plants are Atriplex nummularia, Atriplex halimus, Atriplex leucoclada and Panicum turgidum. They are rich with their nutritive values and their water requirements are low. Using semi woody cuts in propagation of Atriplex nummularia recorded highest number of formed roots and using basic cuts or intermediate cuts provided highest of number of formed roots/plant. It is concluced that, Kochia indica as an halophytes may be used not only as a tool for combating desertification in arid and semi-arid regions through depleting soil salts, but also offer new salt-tolerant forage crops that can grow better under organic agriculture

No doubt that groundwater is an essential source of water resources in many regions in the world particularly in arid desert areas as in the case of Egypt. Egypt’s deserts rely on groundwater where no other reliable source is available. The rapid growth of the population and the need for food at a reasonable price lead Egypt to extend its agricultural expansion to the deserts where 1.5 million feddans (1 Feddan = 4200 m2) are entering the plan for cultivation. This book focuses on the groundwater in Egypt’s deserts, its availability, quantity, quality, uses, and the future agricultural expansion. The book consists of 17 chapters in five parts.
Part “Introductory Section” is an introduction and contains two Chaps. “Intro-duction to “Groundwater in Egypt’s Deserts”” and “An Overview of the Egyptian Deserts’ Resources”. Part “Groundwater Occurrence and Ecosystem Services”. Part “Groundwater Exploration, Quantity, Quality, and Their Management” deals with Groundwater Exploration, Quantity, Quality and their Management in 8 Chap-ters . On the other hand, the topic (Transboundary groundwater management issues in the Nubian Sandstone Aquifer System (NSAS) is covered in Chap. “Transboundary Groundwater Management Issues in the Nubian Sandstone Aquifer System (NSAS)”
The last Part of the book is to conclude the book with a chapter titled (Update, Conclusions and Recommendations of the Groundwater in Egypt’s Deserts”.
