Awareness, Knowledge and Attitudes Toward Management of Avulsed Permanent Incisors Among Primary School Teachers.

Introduction: Dental trauma is known as main concern for public health and is a prevalent issue among children as it leads to functional, aesthetic, and psychological complications. This study aimed to evaluate the awareness and knowledge of primary school teachers regarding emergency first aid management for tooth avulsion at Agadir.

Methods: The study was conducted in 46 randomly selected primary schools in Agadir and included all teachers from these schools.

Surgical management of compound odontoma associated with unerupted tooth: a case report.

Compound odontoma has been reported to be the most common of all odontogenic neoplasms and tumor- like lesions. It is a slow-growing, asymptomatic neoplasms found incidentally during a routine radiography examination. In general, the clinical indicators of odontoma may include eruption disturbance (non-eruption of permanent teeth, retention of deciduous teeth), expansion of the cortical bone, teeth malposition and pain.

Oligodontia and Facial Phenotype Associated with a Rare Syndrome.

Introduction: Oligodontia is a dental abnormality in which the patient is missing teeth. It is a hereditary disorder characterized by agenesis of more than six primary or permanent teeth, excluding the wisdom teeth. Oligodontia is often related with an abnormal size of teeth, conical shape, taurodontism, frequent enamel abnormalities, and delayed eruption.

An unusual intraoral lipoma: case report and review of the literature.

Lipoma is a common tumor of soft tissue with rare occurrence in oral cavity accounting for only 1-4% of benign oral tumours. It may be noticed only during routine dental examinations. Most of them rarely cause pain, resulting in delay to seek treatment.

Surface plasmon resonance analysis of the binding mechanism of pharmacological and peptidic inhibitors to human somatic angiotensin I-converting enzyme.

Somatic angiotensin I-converting enzyme (ACE) possesses two catalytic domains and plays a major role in the regulation of blood pressure, thus representing a therapeutic target for the treatment of hypertension. We present a comprehensive surface plasmon resonance (SPR) study of the interaction of human somatic ACE with the pharmacological inhibitors captopril and lisinopril, the bradykinin potentiating peptide BPP-11b, and the food peptidic inhibitors from bovine αs2-casein, F(174)ALPQYLK(181) and F(174)ALPQY(179). SPR binding curves recorded with the high potency inhibitors captopril, lisinopril, and BPP-11b were evaluated both by regression analysis and by kinetic distribution analysis.

Binding of divalent metal ions to 1-25 β-caseinophosphopeptide: an isothermal titration calorimetry study.

To better understand the mechanism of metal ion transport through the gastrointestinal tract to their absorption sites, isothermal titration calorimetry (ITC) was used to investigate the binding of dicationic metals to β-CN(1-25)4P, a β-casein tetraphosphorylated peptide. ITC technology was found suitable for studying weak bonds between metal ions and phosphopeptides and provided a direct means of thermodynamic and stoichiometric characterisation of complex formation. Thus, one mole of β-CN(1-25)4P binds two moles of Ca(2+), Mg(2+) or Zn(2+) under experimental conditions close to those of the ileum (pH 8, 37°C), with rather low binding affinity constants (K=4900-11,200M(-1)).

Catalytic spectrophotometric determination of iodide in pharmaceutical preparations and edible salt.

The catalytic effect of iodide on the oxidation of four dyes: viz. variamine blue (VB), methylene blue (MB), rhodamine B (RB), and malachite green (MG) with different oxidizing agents was investigated for the kinetic spectrophotometric determination of iodide. The above catalyzed reactions were monitored spectrophotometrically by following the change in dye absorbances at 544, 558, 660, or 617 nm for the VB, RB, MB, or MG catalyzed reactions, respectively.

Kinetic catalytic determination of trace levels of iodide based on the oxidation of basic dyes with hydrogen peroxide monitored potentiometrically using simple PVC electrodes.

Four sensitive catalytic potentiometric methods have been developed for trace levels determination of iodide based on its catalytic effects on the oxidation of four dyes: viz. variamine blue (VB), rhodamine B (RB), methylene blue (MB) and malachite green (MG), with H(2)O(2) in H(3)PO(4) medium at 25±0.5°C.

[Hydrogeochemistry of reservoirs of Imfout, Daourat and Sidi Maâchou dams (Morocco)].

Monitoring of the physico-chemical parameters of the water, nutriments and chlorophyll was carried out. Also, of the grading and physico-chemical characteristic of the sediment. Tests of fixation and salting out of phosphor were undertaken.

[Hydrological and edaphic structure of an oyster-farming site: Duna Blanca (Bay of Dakhla, south Morocco)].

Morocco shelters lagoons, estuaries and bays along its paralic coasts which are among the most productive in the world. The Bay of Dakhla is the longest and the most important site in Morocco due to its halieutic richness. In fact, this bay is an ecosystem with great potential in terms of aquaculture, mainly shellfish farming, and shelters favorable zones for tapiculture, mytiliculture and ostreiculture, in accordance with ecological planning.

Decolourization of dye-containing effluent using mineral coagulants produced by electrocoagulation.

The colour and colour causing-compounds has always been undesirable in water for any use, be it industrial or domestic wastewaters. The discharge of such effluents causes excessive oxygen demand in the receiving water and then a treatment is required before discharge into ecosystems. This study examined the possibility to remove colour causing-compounds from effluent by chemical coagulation, in comparison with direct electrocoagulation.

[Survey of the cycle of reproduction of red algae Gelidium sesquipedale (Turner) Thuret (case of the maritime zone of El Jadida-Jarf lasfer of Morocco)].

The industrial exploitation of the agarophyte, Gelidium sesquipedale, is an important part of the economy of Morocco, however the species is in danger of being overexploited. The development of research on the biological cycle of the species enbles a better understanding of environmental influencies on its reproduction periods and of the effect of pulling up on the growth of the thalli. This should assist in helping to avoid excessive collection of the species and to reinforce a period of rest where no collection takes place.

[Thoracic gossypibomas].

Objectives: Intrathoracic gossypiboma are exceptional, but diagnosis and treatment are difficult. The purpose of this study was to recall the clinical and radiological aspects of intrathoracic gosssyibomas and discuss the medicolegal consequences.

Material And Methods: From January 1990 to June 2003, eight cases of gossypiboma were treated in our unit.

[Conceptuel model of transport of trace metals (chromium and nickel) in the Sebou River--Morocco].

This paper examines trace metals' behavior, mainly chromium and nickel, in Sebou River in the level located between Sidi Harazem upstream and Azib Soltane downstream. The studied level is the most exposed to pollution with heavy metals rejected by Fès stream. This often condemns tens of kilometers of Sebou and leads to a threat and an important handicap for some catches of water located downstream of the town of Fès.

[Aquatic ecosystem modelling approach: temperature and water quality models applied to Oualidia and Nador lagoons].

The objective of this work is to develop an aquatic ecosystem and apply it on Moroccan lagoon systems. This model will keep us abreast of the yearly development of the main parameters that characterize these ecosystems while integrating all the data that have so far been acquired. Within this framework, a simulation model of the thermal system and a model of the water quality have been elaborated.
