In this paper, we have explained the economic importance of intangible assets to make the right decision on how to use them in an optimal way. At first, we tried to define the intangible assets, through an economic analysis of the characteristics of these assets, in addition to that we explained he most important way to evaluate them. Then in the next step, and by applying to Pfizer, we calculated some indicators before and after deleting the intangible assets, to notice their impact in creating value on the company. The most important result that was reached is that intangible assets have a direct role in creating value in Pfizer, and by removing them from the financial statements, the company's performance will decline and cannot be dispensed with in the evaluation of the company.

This research aims to clarify the relationship between corporate social responsibility and financial performance, as most of the results of previous studies indicate a positive relationship between them, Other studies indicate that there is no direct relationship, based on a survey of a sample of economic institutions, while few see that there is a relationship or an opposite effect. The most important finding of this study is that the most correct decision, according to the analysis of some studies, is that there is of course an effect of social obligation on financial performance, but this effect is not direct.

The aim of this article is to study the reality of sustainable development in Algeria for the period 2008-2018 through some economic, social and environmental indicators. It was based on a descriptive analytical method and a set of statistical indicators. The study concluded that Algeria is still far from achieving the goals of sustainable development, and we find many challenges, but what we confirm is that Algeria has the capabilities and resources that make it competitive in the developed countries in the field of sustainable development.

Ce papier a pour objectif d'élucider les impacts de la crise sanitaire actuelle sur l'économie mondiale et plus précisément sur le secteur du transport aérien en se penchant sur le cas du groupe franco-néerlandais Air France-KLM. Le Covid-19 a provoqué une crisesociétale multidimensionnelle qui a impacté durement le secteur du transport aérien, car plusieurs compagnies faute de gains pour cause de l'arrêt d'activités, ont procédé à la mise au chômage d'une partie importante de leur personnel. Le groupe objet de notre étude n'a pas échappé à cette crise. Ces pertes nettes seulement pour l'année 2020 ont été estimées à 7,1 milliards d'euros en plus des licenciements. Après deux années de pandémie, Air France reste optimiste pour l'avenir. Elle doit d'abord solder les conséquences du Covid-19 qui lui a encore fait perdre 3,3 milliards d'euros en 2021, en lançant une nouvelle recapitalisation avec l'aide de la puissance publique.

Giant cell tumor of bone (GCTB) is generally considered a benign tumor, but it can exhibit locally aggressive behavior. The two main surgical treatment options for GCTB are intralesional curettage and en-bloc resection. This study examined the long-term GCTB recurrence rates among Tunisian patients after surgery. A study including 36 patients diagnosed with GCTB was conducted. These patients underwent surgical procedures, specifically intralesional curettage and in bloc resection. Subsequently, we monitored these patients for a two-year post-operative period. Statistical analyses, including Kaplan-Meier survival analysis, Cox proportional hazards regression, and chi-square tests, were performed to identify and evaluate factors associated with local recurrence. Our analysis showed a significant association between surgical treatment and the occurrence of local recurrence (  < 0.01). Interestingly, the rate of local recurrence was notably higher among patients who underwent intralesional curettage (13 out of 21; 61%) compared to those who received en bloc resection (2 out of 15; 13%) (all  < 0.01). En-bloc resection is a reliable treatment choice for GCTB, demonstrating a lower risk of recurrence compared to intralesional curettage. These findings highlight the importance of selecting the appropriate surgical approach to minimize recurrence and improve patient outcomes.

Crop wild relatives (CWR) are wild species that are more or less genetically related to crops that can be used to introgress useful genes for improvement of productivity, resistance to biotic and abiotic stresses and quality of cultivated crops. They are important in crop improvement to achieve food security for an increasing population and to overcome the challenges caused by climate change and the new virulence of major diseases and pests. These genetic resources are increasingly threatened in their natural habitats through over-exploitation and land reclamation and degradation. Therefore, their efficient and effective conservation would be taxonomically and genetically valuable and will contribute to maintaining and promoting the sustainability of crop diversity, facilitating agricultural production and supporting the increasing demand for food, feed and natural resources. A checklist of 5780 Crop Wild Relatives (CWR) taxa from North Africa was obtained using the CWR Catalogue for Europe and the Mediterranean (PGR Forum). Of which consists 76% of the flora of North Africa. The checklist contains 5588 (~97%) native taxa and 192 introduced. Families with higher taxa richness are Fabaceae, Asteraceae, and Poaceae. These three families constitute more than 33% of the total taxa included in the checklist. About 9% (502) CWR taxa identified as a priority for conservation in North Africa using four criteria, the economic value of the crop, the relatedness degree of wild relatives to their crop, threat status using IUCN red list assessment, and finally the centre of origin and/or diversity of the crop. Of these, 112 taxa were assigned high, 268 medium and 122 low priorities for effective conservation. Those assessed as threatened using IUCN Red list and national assessment represent approximately 2% (119 taxa) of the CWR in the region. However, 21 taxa are assessed as critically endangered (CR), 53 as endangered (EN), and 45 as vulnerable (VU). Wild relatives of some globally important crops are present, with those related to wheat (Triticum aestivum L. and T. durum L.) and barley (Hordeum vulgareL.) among the highest priority crops for the North Africa region. Amongst CWR assessed as threatened, only 8 (6.7%) CWR are related to food crops, Avena agadiriana B.R. Baum. et G. Fedak (VU), A. atlantica B.R. Baum et G. Fedak (VU), A. murphyi Ladiz. (EN), Beta macrocarpa Guss. (EN), Olea europaea subsp. maroccana Guss. (VU), Rorippa hayanicaMaire (VU) and Aegilops bicornis (Forssk.) Jaub. et Spach (VU). The wild relative of Safflower Carthamus glaucus M. Bieb is restricted to Egypt and Libya and assessed as rare in Egypt. The information available about the conservation and threat status of CWR in North Africa still lags behind, and more investigations are required.

The present study has been designed to explore the molecular mechanism and signaling pathway targets of chlorogenic acid (CGA) and its main hydrolysates, caffeic (CA) and quinic acid in the protective effect against glutamate-excitotoxicity. For this purpose 8-DIV cortical neurons in primary culture were exposed to 50 μM l -glutamic acid plus 10 µM glycine, with or without 10–100 μM tested compounds. Chlorogenic acid and caffeic acid via their antioxidant properties inhibited cell death induced by glutamate in dose depended manner. However, quinic acid slightly protects neurons at a higher dose. DCF, JC-1 and Ca 2+ sensitive fluorescent dye fura-2, were used to measure intracellular ROS accumulation, mitochondrial membrane potential integration and intracellular calcium concentration [Ca 2+ ] i . Results indicate that similarly, CGA acts as a protective agent against glutamate-induced cortical neurons injury by suppressing the accumulation of endogenous ROS and restore the mitochondrial membrane potential, activate the enzymatic antioxidant system by the increase levels of SOD activity and modulate the rise of intracellular calcium levels by increasing the rise of intracellular concentrations of Ca 2+ caused by glutamate overstimulation. PKC signaling cascade appear to be engaged in this protective mechanism. Interseling, CGA and CA also exhibit antiapoptotic properties against glutamate-induced cleaved activation of pro-caspases; caspase 1,8 and 9 and calpain (PD 150606,Calpeptin and MDL 28170).These data suggest that neuroprotective activity of CGA ester may occurs throught its hydrolysate,the caffeic acid and its interaction with intracellular molecules suggesting that CGA exert its neuroprotection via its caffeoly acid group that might potentially be used as a therapeutic agent in neurodegeneratives disorders associated with glutamate excitotoxicity.

Recent studies demonstrate that glyphosate exposure is associated with oxidative stress and some neurological disorders such as Parkinson’s pathology. Therefore, phytochemicals, in particular phenolic compounds, have attracted increasing attention as potential agents for neuroprotection. In the present study, we investigate the impact of glyphosate on the rat brain following i.p. injection and the possible molecular target of neuroprotective activity of the phenolic fraction from Morus alba leaf extract (MALE) and its ability to reduce oxidative damage in the brain. Wistar rats from 180 to 240 g were i.p. treated with a single dose of glyphosate (100 mg kg −1 b.w.) or MALE (100 μg mL −1  kg −1 b.w.) for 2 weeks. Brain homogenates were used to evaluate neurotoxicity induced by the pesticide. For this, biochemical parameters were measured. Data shows that MALE regulated oxidative stress and counteracted glyphosate-induced deleterious effects and oxidative damage in the brain, as it abrogated LDH, protein carbonyls, and malonyldialdehyde. MALE also appears to be able to scavenge H 2 O 2 levels, maintain iron and Ca 2+ homeostasis, and increase SOD activity. Thus, in vivo results showed that mulberry leaf extract is a potent protector against glyphosate-induced toxicity, and its protective effect could result from synergism or antagonism between the various bioactive phenolic compounds in the acetonic fraction from M. alba leaf extract.

Background Misuse and overuse of antibiotics comprise leading causes of antimicrobial resistance. The study aims to assess the pattern of antibiotic prescription among primary healthcare general practitioners in the South Batinah Governorate of Oman. Method A cross-sectional study of 600 antibiotic prescriptions issued in the South Batinah Governorate in 2019 was conducted to verify the triggering diagnoses and determine the appropriateness of the prescribed antibiotic. Logistic regression analysis was used to determine the association between predictors and inappropriate use. Results Respiratory infections accounted for 62% of antibiotic prescriptions, of which 92.2% were inappropriately prescribed. Extended-spectrum antibiotics were inappropriately prescribed in 33.3% of cystitis cases, while 14.3% of gastroenteritis received incorrect spectrum of antibiotics. Amoxicillin represented 46.2% of antibiotic prescriptions, of which 84.4% were unnecessarily prescribed. Lower inappropriate antibiotic prescribing rate was linked to patients ≥ 18 years (OR = 0.46, 95% CI: [0.26, 0.82]), those who underwent laboratory tests (OR = 0.22, 95% CI: [0.12, 0.39]), and consultations at health centers (OR = 0.44, 95% CI: [0.24, 0.79]). Arabic-speaking physicians were more likely to prescribe antibiotics inappropriately. Conclusion Inappropriate antibiotic prescription was frequently observed in mild respiratory infections and associated with specific patient and physician characteristics. Appropriateness of antibiotic prescriptions issued can be improved through enhanced testing capacities as well as implementation of physician and community awareness campaigns. Highlights • Inappropriate prescriptions were common among respiratory symptoms. • Amoxicillin was the most common antibiotic prescribed inappropriately. • Laboratory–tested patients were less likely to receive inappropriate antibiotics. • Inappropriate antibiotics were commonly prescribed by Arabic-speaking physicians. • Health centers’ primary care physicians rarely prescribe inappropriate antibiotics.
