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.

[Stress echocardiography and mitral stenosis: what interest?].

The stress echocardiography is used extensively as a diagnostic and prognostic tool and the assessment of ischemic cardiopathies. Its use in valvulopathies is more limited, but is increasing with time. The discrepancies between the functional symptoms and hemodynamics at rest is frequently met in patients with mitral stenosis.

[Distribution of cardiovascular risk factors in a Tunisian cohort of 6901 coronary patients].

The Tunisian epidemiological data on cardiovascular disease in the hospital environment are scarce. The aim of this study was to evaluate the frequency of cardiovascular risk factors and their association in patients hospitalised for coronary disease in coronary care units at Rabta, Charles Nicolle, Habib Thameur and Military hospitals, Tunis, over the period 1994-1998. The clinical features of 6901 patients (75.

[Knowledge, treatment and control of hypertension. Results of a multicenter study of patients hospitalized for cardiac ischemia].

The study objective was to assess the prevalence, level of treatment, and control of hypertension in CHDs patients. We conducted a cross-sectional survey on 1109 patients hospitalised for a first episode of MI in the main hospitals of the District of Tunis during the period 1999-2000. Hypertension and control level are defined according to the JNC recommendations.
