Abstract
Naringenin, a natural dihydrochalcone flavonoid, exhibits diverse pharmacological properties. This study investigates the hypolipidemic effects of Nar-NPs on obese mice. The characteristics of Nar-NPs, including morphology, particle size, zeta potential, UV-vis, and FT-IR spectra, were examined. The anti-obesity properties of Nar-NPs were evaluated in obese rats, considering LD50, 1/20 LD50, and 1/50 LD50 for treatment preparation. Results indicated that synthesized Nar-NPs were uniform, spherical, and well-dispersed, with a size of 130.06 ± 1.98 nm and with a zeta potential of -25.6 ± 0.8 mV. Nar-NPs exhibited enhancement in the cumulative release of naringenin (56.87 ± 2.45 %) as compared to pure naringenin suspension 87.83 ± 1.84 % in 24 h of the study. The LD50 of Nar-NPs was determined as 412.5 mg/kg.b.w. HFD induced elevated glycemic, oxidative stress, and inflammatory biomarkers while reducing HDL-C, GSH, and superoxide dismutase (SOD) levels. Administration of Nar-NPs significantly mitigated body weight, glucose, insulin, leptin, TC, TG, SREBP1c, pAMPK, PPAR-α, as well as vanin-1, MCP-1, and iNOS mRNA gene expression. Histological investigations supported the biochemical and PCR findings. In a nutshell, the study suggests that the Nar-NPs could serve as a promising and viable pharmacological strategy for the treatment of obesity-related disorders.

Abstract
BACKGROUND The miracle herb Nigella sativa (N. sativa) is a member of the Ranunculaceae family that possesses many properties, such as antioxidant, anticancer, analgesic, antibacterial, and anti-inflammatory. Thymoquinone (TQ) is the primary ingredient that makes up N. sativa, which is responsible for its many properties. So, our research focused on the biological role of TQ and its anticancer activities. METHODS A wide range of TQ concentrations (50µg/µl, 25µg/ µl, and 12.5µg µl) was prepared and evaluated for their potential regulatory role in cell lines of hepatocellular carcinoma (HepG2 cell line) compared with normal hepatocytes cells, untreated and DMSO-treated cells. RESULTS The more significant level of LDH obtained after TQ treatment compared to untreated cells provides evidence of the cytotoxic effects of TQ on HepG2 cells. Notably, the normal hepatocyte cells subjected to the same concentrations of TQ showed neglected influence in cell viability rate, indicating the selective regulatory role of TQ in cancer cell proliferation. Interestingly, as a critical mediator of malignancy transformation, the nuclear factor-kappa B expression level (NF-κB) significantly decreased in a time and dose-dependent manner of TQ treatment. Furthermore, we investigated whether TQ regulates the expression of deleted liver cancer 1 (DLC1) and Caspase 3 (Casp3). Notably, the treatment with TQ showed increased expression levels of DLC1 and Casp3 upon treatment. TQ extract sufficiently mediated the secretion of the released pro-inflammatory cytokines from treated cells. This regulation of released cytokines by TQ may affect the activation of NF-κB in treated cells. CONCLUSION These results indicate that TQ mediates the activation of Casp3, DLC1, and NF-κB, providing a new function of TQ in treating hepatocellular carcinoma (HCC).

Abstract
OBJECTIVES To perform a systematic literature review and meta-analysis on endothelial cell (EC) markers that are involved and dysregulated in systemic lupus erythematosus (SLE) in relation to disease activity, as EC dysregulation plays a major role in the development of premature atherosclerosis in SLE. METHODS Search terms were entered into Embase, MEDLINE, Web of Science, Google Scholar and Cochrane. Inclusion criteria were 1) studies published after 2000 reporting measurements of EC markers in serum and/or plasma of SLE patients (diagnosed according to ACR/SLICC criteria), 2) English language peer reviewed articles, and 3) disease activity measurement. For meta-analysis calculations, the Meta-Essentials tool by Erasmus Research Institute and of Management (ERIM) was used. Only those EC markers, which were 1) reported in at least two articles and 2) reported a correlation coefficient (i.e. Spearman's rank or Pearson's) between the measured levels of the EC marker and disease activity were included. For meta-analyses, a fixed effect model was used. RESULTS From 2133 hits, 123 eligible articles were selected. The identified SLE-related endothelial markers were involved in EC activation, EC apoptosis, disturbed angiogenesis, defective vascular tone control, immune dysregulation and coagulopathy. Meta-analyses of primarily cross-sectional studies showed significant associations between marker levels and disease activity for the following endothelial markers: Pentraxin-3, Thrombomodulin, VEGF, VCAM-1, ICAM-1, IP-10 and MCP-1. Dysregulated EC markers without associations with disease activity were: Angiopoeitin-2, vWF, P-Selectin, TWEAK and E-Selectin. CONCLUSIONS We provide a complete literature overview for dysregulated EC markers in SLE comprising a wide range of different EC functions. SLE-induced EC marker dysregulation was seen with, but also without, association with disease activity. This study provides some clarity in the eminent complex field of EC markers as biomarkers for SLE. Longitudinal data on EC markers in SLE are now needed to guide us more in unravelling the pathophysiology of premature atherosclerosis and cardiovascular events in SLE patients.

Abstract
Depressive disorders affect individual's thoughts, feelings, and social interactions. Enhancing emotional competencies of depressed individuals may alleviate their suffering. Purpose: This study aimed to compare depression severity and emotional intelligence before and after emotional intelligence training in patients with depressive disorders. Methods: A nonrandomized trial (one-group pretest-posttest) research design was applied to 69 patients purposively recruited. The patients' sociodemographic and clinical data were collected. The Beck Depression Inventory-II and Trait Emotional Intelligence Questionnaire-Short Form were completed before and immediately after an 8-weeks of focused weekly group training. Results: A significant improvement in the scores of well-being, self-control, emotionality, and sociability; total emotional intelligence scores; and total depression scores was perceived after training (Z = 5.601, 4.398, 5.686, and 3.516; 4.943; and 2.387, respectively). Implications for Nursing Practice: As emotional intelligence can be learned; it may be a target for interventions when dealing with patients with depressive disorders by strengthening their emotional intelligence.

Abstract
Abstract
Background
End-stage renal disease (ESRD) has significantly increased in developing countries such as Egypt [1]. There are many sites for arteriovenous fistula (AVF) creation. The most common sites for AVF are radio-cephalic AVF (RC-AVF) followed by brachio-cephalic AVF (BC-AVF) [2]. To date, there are no significant studies discussing the possible correlation between the AVF location and abnormalities in the right ventricle (RV) in hemodialysis (HD) patients.
Objective
To determine the best location for AVF in order to ensure the least possible hazardous side effects of the AVF on the RV.
Methods
Our study, designed as an interventional study, included 50 ESRD patients referred for primary AVF construction to start HD for the first time. Patients were divided into two groups, 25 patients each. one group underwent a RC-AVF construction and the other had a BC-AVF. We assessed the RV by two dimensional transthoracic echocardiography (2D TTE) twice for each patient, firstly just before the AVF surgery and secondly three months after AVF construction.
Results
There was a statistically significant difference in between study groups regarding change in RV Tei index (p=0.001) with a decrease in the radial group (Mean ± SD = −0.19±0.2) and an increase in the brachial group (Mean ± SD = 0.02±0.12), and regarding the right ventricular outflow tract proximal diameter (p<0.001) with a decrease in the radial group (Mean ± SD = −2.32±5.49) and a larger increase in the brachial group (Mean ± SD = 2.94±3.14). Changes in the other RV dimensions and functional parameters did not show statistically significant difference.
Conclusion
After three months follow up, despite the fact that all the RV parameters remained within the normal range, the RV indices with the RC-AVF were associated with either improvement or less decline than with the BC-AVF.

Abstract
Background Mycobacterium bovis notoriously causes detrimental infections in bovines and humans. In this study, 1500 buffaloes and 2200 cattle were tested by single intradermal comparative cervical tuberculin test and compared with the detection rates of M. bovis isolation, real-time and simplex PCR, and flow Cytometry. Results The tuberculin test is the reference test in Egypt, the positive rate was 54/3700 (1.5%) composed of 18/1500 (1.2%) buffaloes and 36/2200 (1.6%) cattle which were mandatorily slaughtered under the Egyptian legislation, after postmortem examination the non-visible-lesion proportion was 39/54 (72.2%) which surpassed the visible-lesion rate 15/54 (27.8%) with (p < 0.0001). The samples from each case were pooled into one sample representing the case, and the isolation rate of M. bovis was 25/54 (46.3%). Real-time PCR using atpE was positive for mycobacteria on the genus level in 18/18 (100%) and 5/5 (100%) of tissue samples and isolates, respectively; simplex PCR detected M. bovis in 44/54 (81.5%) and 25/25 (100%) of tissue samples and isolates, respectively. Flow Cytometry evaluation of the CD4+, CD8+, WC1+δγ, and CD2+ cell phenotypes showed increased counts in the tuberculin-positive cases compared with negative cases (p < 0.0001), and these phenotypes in the tuberculin-positive cases increased after antigen stimulation than in the negative cases (p < 0.0001). Detection rates of PCR techniques and flow Cytometry exceeded that of bacterial isolation (p < 0.0001) and exhibited a strong correlation. Conclusions The skin test suffers from interference from non-tuberculous mycobacteria able to cause false-positive reactions in cattle and other species. Real-time PCR using atpE, conventional PCR targeting RDs, and flow Cytometry are rapid and accurate methods that correlate with the isolation and can be promising for detection and confirmation of infected live and slaughtered cases.

Abstract
PURPOSE To compare the changes in quality of life in edentulous patients with single implants supporting mandibular overdentures with two different attachment types before implant placement and after 6 and 24 months. MATERIALS AND METHODS Eighty edentulous patients were recruited, and all patients completed the validated Oral Health Impact Profile (OHIP)-EDENT-19 questionnaire before implant surgery. A single implant was placed in the midline of the edentulous mandibles. All implants were allowed to heal for 3 months. After the healing period, randomization into one of two groups was accomplished using sealed envelopes: group A (ball attachment) and group B (locator attachment). The same questionnaire was completed 6 and 24 months postplacement. Mann-Whitney U test for independent samples was used to compare the two groups, while Freidman test was used for comparison within each group. Two-sided P values less than .05 were considered statistically significant. RESULTS There was an improvement in all domains of the OHIP-EDENT-19 scores at the 6- and 24-month follow-ups for both groups. The social disability domain showed a statistically significant improvement for group A at 6 and 24 months postplacement (P = .004, .005). Within group A, there was a statistically significant improvement within all seven domains (P = .001); while in group B, four domains (functional limitation, physical pain, psychosocial discomfort, and physical disability) and the total score (P = .001) showed a statistically significant improvement. CONCLUSION Both attachments improved the patients' quality of life at 24 months postplacement. The ball attachment demonstrated a significant improvement regarding the social effects of the prostheses.

Abstract
In this paper, we present the interaction between a five-level [Formula: see text]-configuration atom and a two-mode quantized field in the presence of the damping with the nonlinearity. According to the generalized nonlinear Jaynes–Cummings model (JCM) and the analytical solution of the Schrödinger equation, the general formula of the wave function for this system under special conditions, where the atom (the field) is initially prepared in the excited state (coherent state), has been found. Under some particular conditions, the five-level [Formula: see text]-type atom can be reduced to the three-level [Formula: see text]-type atom. Some physical aspects of the atom-field entangled state showing the entanglement degree, such as the field entropy. Moreover, we evaluate some of their non-classical statistical aspects such as atomic inversion. The effects of the physical parameters such as a Kerr medium, detuning parameter and the intensity-dependent coupling on the temporal behavior of the latter mentioned non-classical statistical aspects have been explored. We show that by choosing the evolved parameters in the interaction process, each of the above non-classical statistical features can be treated. We found that the parameters have an important influence on the properties of these phenomena.

Abstract
BACKGROUND The Shiga toxin-producing Escherichia coli (STEC) represented a great risk to public health. In this study, 60 STEC strains recovered from broiler and duck fecal samples, cow's milk, cattle beef, human urine, and ear discharge were screened for 12 virulence genes, phenotypic and genotypic antimicrobial resistance, and multiple-locus variable-number tandem-repeat analysis (MLVA). RESULTS The majority of strains harbored Shiga toxin 1 (stx1) and stx1d, stx2 and stx2e, and ehxA genes, while a minority harbored stx2c subtype and eaeA. We identified 10 stx gene combinations; most of strains 31/60 (51.7%) exhibited four copies of stx genes, namely the stx1, stx1d, stx2, and stx2e, and the strains exhibited a high range of multiple antimicrobial resistance indices. The resistance genes blaCTX-M-1 and blaTEM were detected. For the oxytetracycline resistance genes, most of strains contained tetA, tetB, tetE, and tetG while the tetC was present at low frequency. MLVA genotyping resolved 26 unique genotypes; genotype 21 was highly prevalent. The six highly discriminatory loci DI = 0.9138 are suitable for the preliminary genotyping of STEC from animals and humans. CONCLUSIONS The STEC isolated from animals are virulent, resistant to antimicrobials, and genetically diverse, thus demands greater attention for the potential risk to human.

Breast cancer is one of the most common causes of death in women worldwide and has harmful influence on their psychological state during therapy. Multikinase inhibitors have become effective drugs for treating a variety of cancer diseases such as breast cancer. A purified short peptide (H-P) was isolated from the natural honey and tested for its potential regulatory role in breast cancer cells compared with the effectiveness of the anticancer drug, Sorafenib (SOR), using MCF-7, EFM-19, and MCF-10A cell lines. Furthermore, we investigated the direct connection between Raf-1 activation and cellular autophagy as potential targets of SOR and H-P extract using RNA interference. Interestingly, the treatment with H-P showed competitive regulation of phosphorylated Raf-1, MEK1/2, and matched autophagy-related LC3B without any detectable toxic effects in the non-tumorigenic epithelial cells. Unlike SOR, the regulation of Raf-1 protein and autophagic machinery by the novel H-P extract showed neglected levels of the released proinflammatory cytokine. This regulation of cytokine secretion by H-P resulted in decreasing the expression level of the transcription factor nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) in treated cells. Moreover, the transfection of MCF-7 cells with small interference RNA (siRNA) antagonist Raf-1 expression markedly reduced the expression of LC3B, while it increased the expression of NF-kB1 and NF-kB2, indicating the potential cross-link between Raf-1, autophagy, and NF-kB effector. Collectively, these findings suggest that H-P-mediated Raf-1, MEK1/2, LC3B, and NF-kB provide a novel and efficacious multikinase inhibitor for treating breast cancer without detectable cytotoxic effects.

Abstract
Dendritic cells (DCs) are efficient antigen-presenting cells (APCs) and potent activators of naïve T cells. Therefore, they act as a connective ring between innate and adaptive immunity. DC subsets are heterogeneous in their ontogeny and functions. They have proven to potentially take up and process tumor-associated antigens (TAAs). In this regard, researchers have developed strategies such as genetically engineered or TAA-pulsed DC vaccines; these manipulated DCs have shown significant outcomes in clinical and preclinical models. Here, we review DC classification and address how DCs are skewed into an immunosuppressive phenotype in cancer patients. Additionally, we present the advancements in DCs as a platform for cancer immunotherapy, emphasizing the technologies used for in vivo targeting of endogenous DCs, ex vivo generated vaccines from peripheral blood monocytes, and induced pluripotent stem cell-derived DCs (iPSC-DCs) to boost antitumoral immunity.

Abstract
Macrophages (Mϕs) play an essential role in maintaining body homeostasis. They perform dual functions produced by different subtypes. Mϕs not only fight against pathogens and foreign bodies such as bacteria or cancer cells but also participate in healing and repairing damaged tissue since they maintain both proinflammatory and anti-inflammatory effects sequentially. Tumors possess the ability to polarize Mϕs from proinflammatory M1 subtype to anti-inflammatory M2-like Mϕs called tumor-associated macrophages, which, in turn, help the tumors to acquire cancer hallmarks. Consequently, this polarization allows tumors to grow and spread. In this light, Mϕs have been a subject of intense study, and researchers have developed protocols to derive different Mϕs subtypes either as a new state-of-the-art therapeutic approach or to understand the cross-talk between cancer and Mϕs. In this review, we present the use of primary Mϕs in adoptive immunotherapy for cancer, illustrate the reciprocating interplay between cancer and Mϕs, and the resulting structural and functional change on both cell types. Furthermore, we summarize the recent cutting-edge approaches of using Mϕs in cancer immunotherapy.

Abstract
Abstract
Introduction/Objective
Introduction: Type-2 diabetes have a risk factor of multiple complications such as coronary artery diseases (CAD), premature atheroscalerosis and diabetic retinopathy. IGF-1 is regulated by a balance of hormones such as growth hormone and insulin. It is important that circulating IGF1 in serum has normal levels to maintain glucose metabolism.
Objectives: Monitoring of IGF-1levels in T2DM with macrovascular complications (CVD) and microvascular complications (retinopathy).
Methods
Subjects and methods: The collection of samples started in June 2018 and ended in December 2018. A total of 114 subjects were enrolled in this study; 98 clinically diagnosed T2D patients who were recruited from the outpatient clinic of the National Institute for Diabetes and Endocrinology “NIDE”, in addition to 16 healthy comparable control subjects (without diabetes). The subjects divided into 3 groups. Group 1; a population of 44 T2D patients with macrovascular complications (28 females and 16 males), the mean age was 57.4 years. Group 2; a population of 54 T2D patients with microvascular complicatios (34 females and 20 males), the mean age was 59.1 years. Group 3; a population of 16 healthy subjects (12 female and 4 males), the mean age was 59.2 years. Levels of FBS, C-peptide, HbA1c, Lipid profile, lipoprotein(a), hs-CRP and microalbuminurea were measured in all subjects. Seum concentration of IGF-1 was measured by commercially immunoenzymatic ELIZA method.
Results
It was found that serum concentration of IGF-1 decreased in diabetic patients groups compared to the control one. The mean±SD of group 1, group 2 and group 3 were (332.2±152.2), (316.9 ±142.2) and (625.4 ± 257.7) respectively.
Conclusion
It was observed that there was a negative correlation between serum IGF-1 levels in T2D patients compared to the control group. Also, it was found that T2D patients with microvascular complications had lower IGF-1 levels than patients with macrovascular ones. It seems that IGF-1 strongly involved in the incidence and pathogenesis of T2DM complications.

Abstract
BACKGROUND Pneumonia is the foremost cause of child death worldwide. M-ficolin is encoded by the FCN1 gene and represents a novel link between innate and adaptive immunity. OBJECTIVES To investigate the FCN1 -144 C/A (rs10117466) polymorphism as a potential marker for pneumonia severity and adverse outcome namely complications or mortality in the under-five Egyptian children. METHODS This was a prospective multicenter study that included 620 children hospitalized with World Health Organization-defined severe pneumonia and 620 matched healthy control children. Polymorphism rs10117466 of the FCN1 gene promoter was analyzed by PCR-SSP, while serum M-ficolin levels were assessed by ELISA. RESULTS The FCN1 A/A genotype and A allele at the -144 position were more frequently observed in patients compared to the control children (43.4% vs 27.6%; odds ratio [OR]: 1.62; [95% confidence interval {CI}: 1.18-2.2]; for the A/A genotype) and (60.8% vs 52.5%; OR: 1.4; [95% CI: 1.19-1.65]; for the A allele); P < .01. The FCN1 -144 A/A homozygous patients had significantly higher serum M-ficolin concentrations (mean: 1844 ± 396 ng/mL) compared with those carrying the C/C or C/A genotype (mean: 857 ± 278 and 1073 ± 323 ng/mL, respectively; P = .002). FCN1 -144 A/A genotype was an independent risk factor for adverse outcomes in children with severe pneumonia (adjusted OR = 4.85, [95% CI: 2.96-10.25]; P = .01). CONCLUSION The FCN1 A/A genotype at the -144 position was associated with high M-ficolin serum levels and possibly contributes to enhanced inflammatory response resulting in the adverse outcome of pneumonia in the under-five Egyptian children.

Abstract
Introduction: Cancer is one of the most difficult challenges faced by humanity due to its many associated issues, such as inability to prevent diseases, treatment safety, and high mortality rate. In cancer, a variety of cellular signaling is activated to ensure malignancy transformation, angiogenesis and metastasis. The most efficient signaling pathway in cancer is mitogen-activated protein kinase (MAPK), which controls malignancy and regulates apoptosis. Methods: Four different flavonoid glycosides have been isolated from Pulicaria jaubertii using the phytochemical characterization of hydro-methanol extract. The purified glycosides (PJs) were investigated for their potential repression of cancer development using human lung epithelial cells and hepatocellular carcinoma (HCC) and compared with Sorafenib (SOR), the standard systemic drug for HCC. In PJ-treated cells, the expression profile of K-Ras, B-Raf, and P53 were detected using qRT-PCR, flow cytometry, confocal microscopy and western blot. Steady-state mRNA and levels of transforming growth factor-beta (TGF-β) and interleukin 8 (IL-8) were monitored in the fluids media at different time points following treatment. Results: Our results showed that the qurictine glycosides (PJ-1 and PJ-9) selectively inhibited the mutant K-Ras/B-Raf proteins expression and interaction in both cancer cells; while SOR showed obvious depletion of total Raf-1 protein in cancer cells and normal cells as well. Interestingly, the combination of PJ-1 or PJ-9 with SOR exhibited restoring cell viability of normal cells via controlling Raf-1 and P53 genes expression. Further, these identified PJ agents significantly adjusted the levels of TGF-β and IL-8 in cancer treated cells accompanied by restoring the activation of P53 expression. These findings were confirmed by docking analysis of PJs ligand and the crystal structure of K-Ras, B-Raf, and ERK transcription factor. Conclusion: The current data provide novel and natural multi-kinase inhibitors with competitive regulation of the mutant proteins; K-Ras and B-Raf and sustained MAPK signaling without any detectable toxic effect in normal cells.

Abstract
BACKGROUND Pediatric-onset SLE (pSLE) is a multisystem autoimmune disease. Recently, the ficolin-2 (FCN2) gene has emerged as a potential candidate gene for susceptibility to SLE. OBJECTIVES The objective of this study was to evaluate the association of the FCN2 gene polymorphisms at positions -986 (G/A), -602 (G/A), -4 (A/G) and SNP C/T (rs3124954) located in intron 1, with susceptibility to pSLE in Egyptian children and adolescents. METHODS This was a multicenter study of 280 patients diagnosed with pSLE, and 280 well-matched healthy controls. The FCN2 promoter polymorphisms at -986 G/A (rs3124952), -602 G/A (rs3124953), -4 A/G (rs17514136) and SNP C/T (rs3124954) located in intron 1 were genotyped by polymerase chain reaction, while serum ficolin-2 levels were assessed using enzyme-linked immunosorbent assay. RESULTS The frequencies of the FCN2 GG genotype and G allele at -986 and -602 positions were significantly more represented in patients with pSLE than in controls (p < 0.001). Conversely, the FCN2 AA genotype and A allele at position -4 were more common in patients than in controls (p < 0.001). Moreover, patients carrying the FCN2 GG genotype in -986 position were more likely to develop lupus nephritis (odds ratio: 2.6 (95% confidence interval: 1.4-4.78); p = 0.006). The FCN2 AA genotype at position -4 was also identified as a possible risk factor for lupus nephritis (odds ratio: 3.12 (95% confidence interval: 1.25-7.84); p = 0.024). CONCLUSION The FCN2 promoter polymorphisms may contribute to susceptibility to pSLE in Egyptian children and adolescents. Moreover, the FCN2 GG genotype at position -986 and AA genotype at position -4 were associated with low serum ficolin-2 levels and may constitute risk factors for lupus nephritis in pSLE.

Abstract
A system of N two-level atoms, Tavis-Cummings Dicke (TC-Dicke) model, interacting with a one-mode electromagnetic radiation field in the presence of the Stark shifts is studied, which is expected to predict new phenomena that are not explored in the original TC-Dicke model. We obtained the potential energy surface of the system using a trial state the direct product of coherent states in each subspace. In the frame of mean-field approaches, the variational energy is evaluated as the expectation value of the Hamiltonian for this state. The order of the quantum phase transitions is determined explicitly and numerically. We estimate the ground-state energy and the macroscopic excitations in the superradiant phase. Moreover, we investigated the critical properties of the TC-Dicke model in the classical spin limit and coherent state. We observed that in the thermodynamic limit, the energy surface takes a simple form a direct description of the phase transition. Moreover, it is found that when the microwave amplitude changes the new phase transition occurs with the Stark shift. The analytical solutions and numerical results, which appear in this paper are agreement with our paper which published recently in Int. J. Mod. Phys. B when we studied the same model using a different coherent state.

Abstract
Objectives: To evaluate Doppler ultrasound and platelet indices for the prediction of preeclampsia (PE).Design: Prospective observational study.Methods: The study included 270 normal pregnancy primigravida <20 years at 20-24-week gestation. Doppler ultrasound was done to detect uterine artery diastolic notch and to measure the pulsation index (PI) and the resistance index (RI). The platelet count (PC), mean platelet volume (MPV), platelet distribution width (PDW) and platelet large cell ratio (Plcr) was measured by automated blood picture.Outcome: Validity of combined tests in prediction of PE.Results: Patients who developed PE had significant higher percentage of diastolic notch, higher mean PI, RI, and significant increase of MPV and PDW than normotensive women (p < .001). Patients with abnormal Doppler and abnormal platelet indices had significant higher incidence of severe PE (p < .001).Conclusion: Abnormal platelet indices combined with abnormal Doppler is a predictor of severity rather than the rate of development of PE.

Abstract
Objective The aim of this study was to determine whether adding mobilization of the outer cavernous sinus membrane as a part of the approach, in large spheno-clinoidal meningiomas without cavernous sinus extension, would reduce bleeding and increase the extent of resection. Methods: This prospective randomized controlled trial was held between February 2016 and April 2017 at Cairo University Hospitals. The study recruited 94 patients with spheno-clinoidal meningiomas without cavernous sinus involvement. Patients were randomly assigned (by a computer based randomization system) into two groups; the treatment group, in which the patients received mobilization of the outer layer of the lateral wall of the cavernous sinus, prior to opening of the dura; and, the control group, in which the patients were operated by a direct opening of the dura without cavernous sinus dissection. The primary outcome of this study was the difference in the amount of blood lost during surgery between both groups of patients. The secondary outcome variables were the estimated blood loss (EBL) calculated according to Mercurelli's formula, the extent of tumor resection and the amount of blood transfused. Results: The amount of blood loss and estimated blood loss (EBL) were significantly less in the "with mobilization group" with the P value being 0.00 and 0.013, respectively. Additionally, the amount of residual tumor was compared between both the groups and it showed that the group of patients who have received mobilization of the outer cavernous sinus membrane had a higher rate of radical resection as expressed by a lower volume of residual tumor (P value 0.005). Conclusion: In large spheno-clinoidal meningiomas without cavernous sinus involvement, routine mobilization of the outer cavernous sinus membrane reduces bleeding. This helps in a better visualization of cranial nerves in a relatively avascular field as it enables the performance of neurovascular dissection in an earlier phase of surgery. It also enables a more radical resection.

Abstract
BACKGROUND Egypt has the highest prevalence of the world hepatitis C virus (HCV) load. Hence, the problem of end-stage liver disease (ESLD) is considered a huge burden on the community. Living donor liver transplantation (LDLT) is the only source of donation in Egypt till now. Survival rates had shown significant improvement in the past decades. This study provides analysis of the mortality rates and possible predictors of mortality following LDLT. It also aids in developing a practical and easy-to-apply risk index for prediction of early mortality. PATIENTS AND METHODS This study is a retrospective study that was designed to analyze data from 128 adult patients with ESLD who underwent LDLT in the Liver Transplantation Unit at Faculty of Medicine, Cairo University. Early and late mortality were identified. All potential risk factors were tested using univariate regression for association with early and late mortality. Significant variables were then entered into a multivariable logistic regression model for identifying the predictors for mortality. RESULTS Sepsis was the most common cause of early mortality. Early mortality and 1-year mortality were 29 (23%) and 23 (18%), respectively. Model for End-Stage Liver Disease (MELD) score, intraoperative packed red blood corpuscles (RBCs), and duration of intensive care unit (ICU) stay were found to be independently associated with early mortality. CONCLUSION A MELD score >20, intraoperative transfusion >8 units of packed RBCs, and ICU stay >9 days are three independent predictors of early mortality. Their incorporation into a combined Risk Index can be used to improve outcomes of LDLT.

Abstract
BACKGROUND The aim of the study is to measure plasma vitamin D levels in a group of Egyptian children with familial Mediterranean fever (FMF) compared to healthy children. METHODS The study enrolled 52 children with FMF and 40 apparently healthy controls. Serum vitamin D level was measured by enzyme-linked immunosorbent assay. RESULTS The mean serum vitamin D level was significantly lower in children with FMF than control group (12.3±3.4 and 21.2±3.5ng/mL, respectively, p<0.001). Vitamin D level was significantly lower in female patients than males (11.3±2.9, 13.2±3.6, respectively p=0.04). No statistically significant relations were detected between vitamin D level and different clinical, laboratory and genetic variables. CONCLUSION Vitamin D levels were lower in Egyptian FMF children than healthy controls. There is a speculation that vitamin D deficiency in FMF patients may be related to inflammation. Further studies with larger number of patients before and after Vitamin D, therapy may be needed. Supplementation with high doses of vitamin D seems appropriate for children with FMF.

Abstract
INTRODUCTION Many scoring systems have been proposed to predict the outcome of deceased donor liver transplantation. However, their impact on the outcome in living donor liver transplantation (LDLT) has not yet been elucidated. This study sought to assess performance of preoperative Model for End-Stage Liver Disease (MELD) score in predicting postoperative mortality in LDLT and to compare it with other scores: MELDNa, United Kingdom End-Stage Liver Disease (UKELD), MELD to serum sodium ratio (MESO), updated MELD, donor age-MELD (D-MELD) and integrated MELD (iMELD). METHODS We retrospectively analyzed data from 86 adult Egyptian patients who underwent LDLT in a single center. Preoperative MELD, MELDNa, MESO, UKELD, updated MELD, D-MELD, and iMELD were calculated. Receiver-operator characteristic (ROC) curves and area under the curve (AUC) were used to assess the performance of MELD and other scores in predicting postoperative mortality at 3 months (early) and 12 months. RESULTS Among the 86 patients, mean age 48 ± 7 years, 76 (88%) were of male sex and 27 (31.4%) had died. Preoperative MELD failed to predict early mortality (AUC = 0.63; P = .066). Comparing preoperative MELD with other scores, all other scores had better predictive ability (P < .05), with D-MELD on the top of the list (AUC = 0.68, P = .016), followed closely by UKELD (AUC = 0.67, P = .025). After that were iMELD, MESO, and MELDNa with the same predictive performance (AUC = 0.65; P < .05); updated MELD had the lowest prediction (AUC = 0.640; P = .04). Moreover, all scores failed to predict mortality at 12 months (P > .05). CONCLUSIONS Preoperative MELD failed to predict either early or 1-year mortality after LDLT. D-MELD, UKELD, MELDNa, iMELD, and MESO could be used as better predictors of early mortality than MELD; however, we need to develop an effective score system to predict mortality after LDLT.

Abstract
BACKGROUND An essential milestone in pediatric transplantation is to find noninvasive biomarkers to monitor acute rejection (AR). In this retrospective (Case-control) study, we examined the role of Fas -670A/G and Fas Ligand (FasL) -843C/T gene polymorphisms in allograft nephropathy in pediatric renal transplant recipients. METHODS In 47 pediatric kidney transplant recipients and 20 healthy controls, Fas -670A/G and FasL -843C/T gene polymorphisms as well as serum soluble Fas Ligand level (sFasL) were measured. RESULTS Serum sFasL levels were significantly higher in transplant recipients children than that in controls (548.25±298.64pg/ml vs 143.17±44.55pg/ml, p=0.0001). There was no significant difference between patients with AR and those without AR in regards to serum sFasL levels (567.70±279.87pg/ml vs 507.85±342.80pg/ml, p=0.56). Fas -670A/G genotypes or alleles were not significantly different between controls and transplant recipients and among transplant recipients with and without AR. (P>0.05 for all). FasL -843C/T genotypes were not different between transplant recipients and controls and among transplant recipients with and without AR (P>0.05 for all). However, Frequency of C allele in transplant patients was significantly higher than that in the control group (44.68% vs 25%, P=0.03). FasL -843C/T alleles were significantly different between patients with and without AR (P=0.03). The percentages of C allele were higher in children with AR (58.82% vs 36.67%). We found that serum FasL and serum creatinine were variables that were independently associated with AR. CONCLUSION This study suggests that FasL gene polymorphisms in peripheral blood might be accurate in detecting cellular AR.

Abstract
Ambulant flexible cystoscopy is the standard procedure in the urological practice for follow-up of Ta-T1 urothelial carcinoma (UC) due to its ability to survey the bladder for a variety of indications. It is the principal means of diagnosis and surveillance of bladder tumors. The follow-up of patients treated for Ta-T1 UC is of great importance because of the high incidence of recurrence and progression of the disease, whereby patients with Ta-T1 UC undergo cystoscopy every three months. The aim of this study to evaluate the procedure of ambulant flexible cystoscopy in proper diagnostic follow-up of Ta-T1 UC, patient's acceptance in regard to pain tolerance, non-hospital stay and expenses. Twenty one patients (18 male and 3 female) were diagnosed before as Ta-T1 UC by rigid cystoscopy and transuretheral resection of bladder (TURB) lesion scheduled for follow up by flexible cystoscopy under local anesthesia using 20 ml 2% lidocain gel on an ambulatory bases. Comparison was done using a cohort of 32 patients who underwent the procedure of follow-up of Ta-T1 cystoscopy and TURB using rigid cystoscopy and resectoscope. Seventeen patients 80.9% (16 male and 2 female) proved to be bladder free from recurrent lesion, 4 patients {19.1 %} (3 males and one female) which revealed recurrent lesions in spite of that the urinary bladder was free in pelvic ultrasonography. Cold cup biopsy from the lesions sent for histopathological examination which revealed recurrence of the tumor in 3 patients (two patients with Ta and one patient T1. TURB was done to have complete resection in 4 patients, the histopathological examination revealed ulcerating mucosa and free lamina propria in 3 specimens, and T2 in the fourth specimen. Comparison between the 2 groups revealed more patient's acceptance for the flexible cystoscopy group as regard pain tolerance, non-hospital stay and expenses. Ambulatory flexible cystoscopy with 20 ml of 2% lidocaine gel anesthesia is tolerated well by patients, with advantage of no hospital stay in the regular follow up of Ta-T1 tumors, pain perception was accepted by all patient provided delayed cystoscopy after lidocaine-gel instillation.

Abstract
OBJECTIVE In this study we assess the value of left atrial dyssynchrony time measured by tissue Doppler imaging (TDI) to predict recurrences after pulmonary vein isolation (PVI) in patients with paroxysmal and persistent atrial fibrillation (AF). METHODS One hundred sixty patients (57 ± 7.5 years, 122 males) with symptomatic drug-refractory paroxysmal and persistent AF, undergoing PVI were enrolled in our study. PA peak time by tissue Doppler imaging (PApeak-TDI) is defined as the time measured from the start of P wave in lead II to the peak of A wave on the tissue Doppler tracing. Left atrial dyssynchrony was measured by subtracting the PApeak-TDI time measured at the mid-inter atrial septum from the PA peak-TDI time measured at the left atrial midlateral free wall, (LA dyssynchrony = PApeak TDI lateral-PApeak TDI septal). RESULTS During a mean follow-up of 12 ± 3 months, recurrences occurred in 50 out of 160 patients. Patients with recurrence of atrial fibrillation had larger left atrial dyssynchrony time (26.5 ± 2.4 ms vs. 23.5 ± 2.3 ms, p < 0.001). Left atrial dyssynchrony time of 25 ms has the best combined sensitivity and specificity (74% and 63% respectively) along with positive predictive value 53% and negative predictive value 85.5%. LA dyssynchrony time ≥ 25 ms was found to discriminate patients prone to AF recurrences over time. Multivariate regression analysis showed that left atrial dyssynchrony time (HR per ms: 1.69, p<0.001) was identified as independent predictor of AF recurrence. CONCLUSION Left atrial dyssynchrony time is good clinical predictor of recurrence of AF after PVI in patients with paroxysmal and persistent AF.

Abstract
BACKGROUND AND OBJECTIVES Cell therapy provides an effective strategy for the treatment of an impaired liver. Human umbilical cord blood progenitor cells have the potential to differentiate into hepatocytes. Progenitor cells transplanted into the spleen could migrate directly into the liver through portal circulation. To track migration of human umbilical cord blood progenitor cells in cirrhotic rat liver after intrasplenic transplantation and to prove the possibility similar behavior of human umbilical cord blood nucleated cells in humans. METHODS AND RESULTS Umbilical cord blood samples from full-term deliveries will be collected after obtaining an informed consent from the mother. The collection procedure will be conducted after completion of delivery and will not interfere with the normal obstetric procedures. Adult male Sprague Dawley rats were subjected to liver cirrhosis by intraperitoneal injection of thioacetamide. Cirrhotic rats were treated with human umbilical cord blood nucleated cells by intra-splenic transplantation. Migration of intrasplenic transplanted human umbilical cord blood cells to the liver was successfully documented with Immunohistochemistry. The liver and spleen from recipient animals were removed. Histopathological and immunohistochemical analysis were performed 20 weeks after intrasplenic injection of the cells. Intrasplenically injected cells migrate to the liver of recipient animals. CONCLUSIONS Human cord blood nucleated cells have the potential to differentiate into hepatocytes and substantially improve the histology and function of the cirrhotic liver in rats. Relocation into liver after intrasplenic transplantation could be detected by immunohistochemistry. Transdifferentiated cells could be efficiently stained with antihuman hepatocytes.

Abstract
Background P-wave indices are appealing markers for predicting atrial fibrillation (AF)
recurrences post ablation. Objective This study evaluates the value of P wave indices to predict recurrences post
pulmonary vein isolation (PVI) in patients with paroxysmal AF. Methods We selected 198 patients (57 ± 8 years, 150 males) with symptomatic
drug-refractory paroxysmal AF undergoing PVI in our hospital. A 12-lead
electrocardiogram was used to measure P wave duration in lead II, P wave terminal
force (PWTF) in lead V1, P wave axis and dispersion. Results During a follow-up of 9 ± 3 months, recurrences occurred in 60 (30.3%) patients.
The patients that had AF recurrence had longer mean P wave duration (122.9 ± 10.3
vs 104.3 ± 14.2 ms, p < 0.001), larger P wave dispersion (40.7 ± 1.7 ms vs 36.6
± 3.2 ms, p < 0.001). P wave duration ≥ 125 ms has 60% sensitivity, 90%
specificity, positive predictive value (PPV) of 72% and negative predictive value
(NPV) of 83.7%, whereas P wave dispersion ≥ 40 ms has 78% sensitivity, 67%
specificity, PPV of 51% and NPV of 87.6% 48/66 (72.7%) patients with PWTF ≤ - 0.04
mm/second vs 12/132(9%) with PWTF > -0.04 mm/second showed recurrence of AF (p
< 0.001). P wave axis was not different between two groups. On multivariate
analysis, P wave indices were not independent from left atrial size and age. Conclusions P wave duration ≥ 125 ms, P wave dispersion ≥ 40 ms and PWTF in V1 ≤ - 0.04 mm/sec
are good clinical predictors of AF recurrences post PVI in patients with
paroxysmal atrial fibrillation; however they were not independent from left atrial
size and age.
