Pseudotumor Sarcoidosis: The Contribution of Thoracic MRI to the Presumption of Benignity of a Pulmonary Lesion Process.

Sarcoidosis is a benign systemic disease; its diagnosis is based on a suggestive radiological presentation, and the isolation of an epithelioid and gigantocellular granuloma (EGGC) without caseous necrosis with the elimination of other causes of granuloma. However, sometimes the radiological presentation is atypical and misleading, posing problems in terms of differential diagnosis. In this report, we present a case of pseudotumor sarcoidosis, in which MRI played an essential role in characterizing the lesion and suggesting its benignity.

Ion uptake and structural modifications induced by nitrogen source in tomato (Solanum lycopersicum Mill. Cv. Ibiza F1).

Interactions between NO(3)(-) and NO(2)(-) were studied at the level of root uptake, ion translocation (NO(3)(-), NO(2)(-), K(+)), ion xylem exudates composition and inorganic cation contents (K(+), Ca(2+), Mg(2+)) using tomato seedling (Solanum lycopersicum Mill cv. Ibiza F1). Nitrite was supplied in the medium as KNO(2) (0, 0.

[Digestive polyposis. Retrospective study of 20 cases].

Background: Three main polyposis syndromes are transmitted as an autosomal dominant disorder: familial adenomatous polyposis (FAP), juvenile polyposis syndrome (JPS) and Peutz-Jeghers syndrome.

Aim: Evaluate this management of digestive polyposis.

Methods: Our study included 20 patients which were collected in th departements of pathology surgery and garstroenterology of MT Maarmouri's Hospital, Nabeul city.

Physiological and biochemical responses resulting from nitrite accumulation in tomato (Lycopersicon esculentum Mill. cv. Ibiza F1).

The sensitivity of hydroponically cultivated tomato (Lycopersicon esculentum Mill. cv. Ibiza F1) submitted to nitrite treatments (0.

Production of activated carbon from a new precursor molasses by activation with sulphuric acid.

Activated carbon has been prepared from molasses, a natural precursor of vegetable origin resulting from the sugar industry in Morocco. The preparation of the activated carbon from the molasses has been carried out by impregnation of the precursor with sulphuric acid, followed by carbonisation at varying conditions (temperature and gas coverage) in order to optimize preparation parameters. The influence of activation conditions was investigated by determination of adsorption capacity of methylene blue and iodine, the BET surface area, and the pore volume of the activated carbon were determined while the micropore volume was determined by the Dubinin-Radushkevich (DR) equation.

Influence of the experimental conditions on porosity and structure of adsorbents elaborated from Moroccan oil shale of Timahdit by chemical activation.

This study records experiments undertaken to determine the suitable conditions for the use of the oil shale of Timahdit, as an adsorbent for water treatment. A simple process was proposed based on chemical activation. The preparation has been carried out by carbonization after impregnation of the precursor with phosphoric acid.

[Early and late hospital mortality in myocardial infarction. Causes and prognostic factors. Apropos of 140 cases].

The purpose of this work is to study the causes of early and late in-hospital mortality of myocardial infarction, to define elements of prognosis and to attempt to prevent the fatal outcome of the coronary disease. This study concerns 107 men and 33 women, between the ages of 30 and 83 years (mean age 62.8 years).
