MEDT analysis of mechanism and selectivities in non-catalyzed and lewis acid-catalyzed diels-alder reactions between R-carvone and isoprene.

Within the context of Molecular Electronic Density Theory (MEDT), this study investigates the Diels-Alder reaction among isoprene (2) and R-carvone (1R) applying DFT simulations, with and without Lewis acid (LA) catalysis. The results show that carvone (1R) acts as an electrophile and isoprene (2) as a nucleophile in a polar process. LA catalysis increases the electrophilicity of carvone, thereby improving the reactivity and selectivity of the reaction by reducing the activation Gibbs free energy.

Prevalence and predictive determinants of overweight and obesity in children aged 0-24 months in Morocco: a cross-sectional study.

Background: Preventing overweight and obesity in early childhood is a priority for healthcare systems worldwide due to the harmful effects on health and economy over the medium and long term.

Objective: The aim of this study is therefore the identification of the determinants predictive of overweight and obesity during the first 24 months of a child's life.

Material And Methods: From May 2021 to January 2022, 1012 mother-child pairs were included in this study and were interviewed at urban and rural health centers in the Skhirat-Temara in Morocco prefecture using a questionnaire.

COVID-19 in Morocco's region: Observational study of prevalence in symptomatic adults using the PANBIOS® rapid antigen test September 2021.

Background: Rapid antigen tests have emerged to deal with the COVID-19 pandemic. Rapid diagnosis of SARS-CoV-2 infection is essential to reduce the spread of the disease. The aim of this study was to estimate the prevalence of COVID-19 infection and test the sensitivity and specificity in Temara-Skhirat in symptomatic adults through PANBIOS® test.

[Genetic hypothesis involving Haglund's syndrome and its association with ankylosing spondylitis: case report].

Haglund´s syndrome is characterized by osterosuperior calcaneal exostosis which irritates the Achilles tendon and manifests mainly as posterior talalgia. We here report the case of a 28-year-old woman on follow up for ankylosing spondylitis. Her mother was on follow up for the same systemic disease, and one of her maternal aunts had undergone surgery due to Haglund's syndrome.

Right anterior minithoracotomy approach for resection of papillary fibroelastoma.

Background: Right anterior minithoracotomy (RAMT) is an alternative to full or partial sternotomy for accessing the aortic valve. The adoption of this approach for aortic valve replacement has been limited by its perceived technical complexity. Resection of a mobile aortic valve tumor is a simple procedure that is conventionally done through a sternotomy.
