Attia, M. M., M. Abdelsalam, M. Y. Elgendy, and A. H. Sherif, Dactylogyrus extensus and Pseudomonas fluorescens dual infection in farmed common carp (Cyprinus carpio), , vol. 173, pp. 105867, 2022. AbstractWebsite

Dactylogyrus extensus and Pseudomonas fluorescens are serious pathogens in Cyprinus carpio aquaculture causing severe impacts and substantial economic losses. During the early spring of 2021, abnormal mortalities were reported among farmed C. carpio. Moribund fish showed anorexia, respiratory distress, dermal ulcers, and septicemia. The water analysis revealed low dissolved oxygen (3.4 mg/L), and high un-ionized ammonia levels (0.65 mg/L). Seventy moribund C. carpio specimens were collected and subjected to parasitological and bacteriological examinations. The monogenetic trematode D. extensus was discovered in wet mounts from the gills of all the examined fish samples (100%). The identity of recovered parasites was confirmed by sequencing and alignment of the 28S rDNA gene. P. fluorescens was concurrently identified in the infested fish samples (58.5%) based on phenotypic characteristics using the API20 E. The identity of bacterial isolates was confirmed further by sequencing and alignment of 16S rRNA gene. The IL-1β and MHCII were upregulated in infested fish in tandem with the severity of infections. P. fluorescens isolates displayed high resistance to most of the tested antibiotics. The study is one of the earlier reports on D. extensus and P. fluorescens co-infections in farmed C. carpio and highlights the need of effective control programs to protect fish health and minimize losses.

Attia, M., M. Saad, N. Salaeh, M. A. I. Salem, S. El-Gameel, S. Soliman, M. K. H., and R. Ramadan, Evaluation of the cytokines response in buffaloes focused on its milk as a newly emerging indicator tracing for toxocariasis, , vol. 170, pp. 105717, 2022/08/01. Abstract

This study aimed to evaluate the immune responses and oxidative stress provoked by Toxocara vitulorum infection in buffaloes with special reference to milk parameters as an emerging tool. The use of the milk tool was reported for the first time in tracing T. vitulorum infection in Egyptian buffaloes. Intestine, milk, serum, and liver samples were gathered from flocks in Cairo and Giza districts to evaluate buffalo immune responses provoked by T. vitulorum. The compositional items and somatic cells of milk were monitored. The intestine and milk were evaluated for interleukin IL-1β, IL-6, and tumor necrosis factor-alpha (TNF-α) by quantitative real-time polymerase chain reaction protocol and the analysis of malondialdehyde (MDA) as an oxidative stress marker. The mean percentages for the total solids, fats, proteins, lactose, salts, pH, and somatic cell count/ml in positive samples were 11.23 ± 0.37, 5.1 ± 0.17, 4.44 ± 0.14, 3.9 ± 0.14, 0.81 ± 0.02, 6.8 ± 0.22, and 4.23 × 10⁶± 1.41 × 10⁵ cells/ml, respectively. A significant difference (p < 0.05) was observed in the mean values of compositional items except for the total protein %, salts %, and pH. For T. vitulorum-contaminated samples, the milk IL-1β, IL-6, TNF-α, and MDA (nmol/ml) were 7 ± 0.23, 18 ± 0.6, 17 ± 0.56, and 3.7 ± 0.12, respectively (which were less than the values for intestinal cytokines). There is a statistical difference (p < 0.05) between positive and negative samples in the intestinal, milk cytokines, and MDA. This study is an initial investigation of the utilization of intestine and milk cytokines in the evaluation of buffalo toxocariasis.

BACKGROUND: Tamoxifen is the standard endocrine therapy for ER+ breast cancer; however, many women still relapse after long-term therapy. 3-Bromopyruvate, a glycolytic inhibitor, has shown high selective anti-tumor activity in vitro, and in vivo. The aim of this study was to evaluate the possible augmentation of the effect of tamoxifen via reprograming cancer cell metabolism using 3-bromopyruvate.

METHODS: An in vitro screening of antitumor activity as well as the apoptotic, anti-metastatic, and anti-angiogenic potentials of the combination therapy were carried out using different techniques on breast cancer cell lines MCF7and T47D. In addition the antitumor effect of the combined therapy was done on mice bearing tumor.

RESULTS: Our results showed modulation in apoptosis, angiogenesis and metastatic potential by either drug alone; however, their combination has surpassed that of the individual one. Combination regimen enhanced activated caspases-3, 7 and 9, as well as oxidative stress, signified by increased malondialdehyde and decreased glutathione level. Additionally, the angiogenesis and metastasis markers, including hypoxia inducing factor-1α, vascular endothelia growth factor, and metaloproteinases-2 and 9 were decreased after using the combination regimen. These results were further confirmed by the in vivo study, which depicted a decrease in the tumor volume and angiogenesis and an increase in oxidative stress as well.

CONCLUSION: 3-bromopyruvate could be a valuable compound when added with tamoxifen in breast cancer treatment.

AbstractThe relationship between health care providers' perceived work climate, organizational commitment, and caring efficacy at pediatric intensive care units, Cairo University

BACKGROUND: Healthy work environment has a significant impact on patients, health care workers, and organizations.

OBJECTIVES: In a trial to set up strategies to control stressors and weaknesses in the work environment, the present study took place in pediatric intensive care units (PICUs) to explore the work environment and its impact on the organization commitment and caring efficacy of health care providers.

METHODS: This study is a descriptive cross-sectional study, conducted over a period of 9 months starting from October 2018. A self-administered questionnaire, based on "The American Association of Critical Care Nurses Standards for Establishing and Sustaining Healthy Work Environments" and "Brewer & Look's organizational commitment scale and theory of self-efficacy," was given to 63 physicians and 73 nurses of PICUs at Cairo University Children Hospital in Egypt.

RESULTS: Nurses were significantly more pleased with their work climate and more committed to their organization and had higher self-efficacy than physicians. A significant direct correlation was detected between healthy environment perception and organizational commitment and between organization commitment and perceived caring efficacy.

CONCLUSION AND RECOMMENDATIONS: The study findings might be incorporated into practice to create a positive PICUs' environment, enhance staff satisfaction, and efficiency to promote quality of care paying attention to the junior staff especially physicians. Additional studies are required to recognize the coping strategies that health care providers use and to test the effectiveness of professional development program along with healthy environment interventions.

Attia, M., K. Shaalan, L. Tounsi, and J. van Genabith, "Automatic Extraction and Evaluation of Arabic LFG Resources", The eighth international conference on Language Resources and Evaluation (LREC'12), Istanbul, Turkey, 22 May , 2012. Abstract609_paper.pdf

This paper presents the results of an approach to automatically acquire large-scale, probabilistic Lexical-Functional Grammar (LFG) resources for Arabic from the Penn Arabic Treebank (ATB). Our starting point is the earlier, work of (Tounsi et al., 2009) on automatic LFG f(eature)-structure annotation for Arabic using the ATB. They exploit tree configuration, POS categories, functional tags, local heads and trace information to annotate nodes with LFG feature-structure equations. We utilize this annotation to automatically acquire grammatical function (dependency) based subcategorization frames and paths linking long-distance dependencies (LDDs). Many state-of-the-art treebank-based probabilistic parsing approaches are scalable and robust but often also shallow: they do not capture LDDs and represent only local information. Subcategorization frames and LDD paths can be used to recover LDDs from such parser output to capture deep linguistic information. Automatic acquisition of language resources from existing treebanks saves time and effort involved in creating such resources by hand. Moreover, data-driven automatic acquisition naturally associates probabilistic information with subcategorization frames and LDD paths. Finally, based on the statistical distribution of LDD path types, we propose empirical bounds on traditional regular expression based functional uncertainty equations used to handle LDDs in LFG.
