Food safety knowledge, attitudes, and practices among food handlers in collective catering in central Morocco.

Food safety is a significant challenge for countries worldwide due to the growing number of food poisoning outbreaks, particularly in the catering sector, which impacts consumer health and imposes additional economic costs on countries. The role of food handlers in restaurants is crucial for guaranteeing this safety and protecting the health of citizens. This pioneering study in central Morocco aimed to assess food safety knowledge, attitudes, and practices (KAPs) among food handlers and to identify key factors influencing adequate knowledge, positive attitudes, and effective practices.

Ataxic gait and dysarthria in a child: pantothenate kinase-associated neurodegeneration as a diagnosis.

Pantothenate kinase-associated neurodegeneration (or previously known as Hallervorden-Spatz syndrome) is a very rare disorder that typically manifests in a child with neurological signs such as gait difficulties, dysarthria, and hyperreflexia, associated potentially with psychiatric symptoms such as cognitive decline. It demonstrates on MRI the typical 'eye of the tiger' appearance, which is due to gliosis and accumulation of iron in the globi pallidi. Other differentials can mimic this appearance on MRI, it is therefore important to search for the involvement of other basal ganglia nuclei and the cerebral cortex, and also to consider the clinical and biological context.

Selective Detection of CO Using Proton-Conducting Graphene Oxide Membranes with Pt-Doped SnO Electrocatalysts: Mechanistic Study by Operando DRIFTS.

To reduce the risk of carbon monoxide (CO) poisoning, there is a strong need for small, compact gas sensors to detect and monitor CO at ppm concentrations. In this study, we focused on detecting CO with electrochemical sensors based on proton-conducting graphene oxide (GO) nanosheets at room temperature. We found that a Ce-doped GO nanosheet membrane fitted with the sensing electrode composed of Pt (10 wt %)-doped SnO nanocrystals exhibits an excellent sensor response to CO at 25 °C.

Exploring the wound-healing and antimicrobial potential of Dittrichia viscosa L lipidic extract: Chemical composition and in vivo evaluation.

Dittrichia viscosa belongs to the Dittrichia genus, it grows abundantly in the east and northeast of Morocco, and traditionally its fresh leaves are crushed and given for topical application after burns, wounds, and infections. In this study, we examine the wound-healing activity of Dittrichia viscosa lipidic extract in vivo, assess its anti-microbial effect, and explore the specific compounds that contribute to these effects. To assess the effectiveness of wound healing, a burn-induced wound model was employed in Wistar rats, and the levels of hydroxyproline as well as histopathological changes in the skin tissues were evaluated.

Phenotypic, molecular, and symbiotic characterization of the rhizobial symbionts isolated from Acacia saligna grown in different regions in Morocco: a multivariate approach.

The introduced species Acacia saligna is a very promiscuous host as it can be efficiently nodulated with a wide range diversity of rhizobia taxa, including both fast and slow-growing strains. Fourteen nitrogen (N)-fixing bacteria were isolated from root nodules of wild Acacia saligna growing in distinct geographic locations in Morocco and were examined for their symbiotic efficiency and phenotypic properties. Multivariate tools, such as principal component analysis (PCA) and hierarchical clustering analysis (HCA), were used to study the correlation between phenotypic and symbiotic variables and discriminate and describe the similarities between different isolated bacteria with respect to all the phenotypic and symbiotic variables.

Ultrasonic-assisted extraction for phenolic compounds and antioxidant activity of Moroccan L. leaves: Simultaneous optimization by response surface methodology and characterization by HPLC/ESI-MS analysis.

This study was designed to optimize the ultrasound-assisted extraction of phenolic compounds and the antioxidant activity of Moroccan extracts using response surface methodology (RSM). A central composite design has been conducted to investigate the effects of three factors: extraction period (X), solvent concentration (X), and solvent-to-material ratio (X) on extraction yield, total phenolic content (TPC), flavonoids content (TFC), and antioxidant activity. The obtained results showed that the experimental values agreed with the predicted ones, confirming the capacity of the used model for optimizing the extraction conditions.
