Effect of geographical origin on the chemical characteristics of acorns: profiling fatty acids, tocopherols, and phenolic composition.

The impact of geographical origin on the chemical composition of acorns from Quercus species has significant attention. This study aimed to explore the phenolic composition of methanolic extracts, tocopherol content, and fatty acid composition of acorn oils from six different populations of acorns. The obtained results revealed that acorn oil from BniMtir exhibited high levels of α-tocopherol (58 mg/kg).

Chemical Composition and Bioactivities of Quercus canariensis Flour Acorns Extracts Growing in Tunisia.

The current study was conducted to investigate the chemical composition of Quercus canariensis flour acorns extracts as well as its biological activities in regards to the growing area using spectrophotometric and chromatographic techniques. The phenolic profile was composed of 19 compounds identified through HPLC-DAD analysis. Coumarin was the most abundant compound quantified in BniMtir, Nefza and ElGhorra and gallic (12.

Air Pollution and Health Risk: Intelligent Mapping.

Air pollution by chemical or bacteriological pollutants is not limited to a geographical area at the discrete border. Also, factors taken into account in the risk analysis such as patient age, seasons, socio-economic background or race are far from being necessary as discrete values. Often used analysis tools are limited to statistical analyzes.

[Intramural hematoma of the thoracic aorta: Medical treatment or surgery?].

Intramural hematoma (IMH) of the aorta is an uncommon entity. This disease shares many characteristics with acute aortic dissection. Treatment of IMH remains controversial.

Epidemiology of infective endocarditis in Tunisia: a 10-year multicenter retrospective study.

Background: Since the first description of infective endocarditis, the profile of the disease has evolved continuously with stable incidence. However, epidemiological features are different in developing countries compared with western countries.

Objective: To describe epidemiological, microbiological and outcome characteristics of infective endocarditis in Tunisia.
