1. Citicoline (cytidine (5') diphosphocholine) has been shown to reverse aging-induced memory deficits, scopolamine-induced amnesia and nucleus basalis magnocellularis lesion-induced learning impairment. 2. This study aimed to evaluate the effects of citicoline on learning and retrieval processes in a complex differential reinforcement of response duration schedule in normal dogs. 3. The effects of citicoline on a stabilized performance were also measured in order to be able to differentiate specific memory effects from non specific influences on the motor, neuro-vegetative and motivational systems. 4. The results demonstrate that citicoline can exert facilitatory effects on learning and memory but also on retrieval processes. The complete absence of effects on the stabilized performance and on the motor, neuro-vegetative and motivational systems constitutes arguments in favour of a selectivity of action on the memory processes.

This paper presents a continuous facility location model with fuzzy methodology. The developments concern mainly to some drawbacks in the initial model which takes it far from being used in practice. A fuzzy modeling method is proposed to estimate the required functions in the initial model. Structure identification in the proposed fuzzy modeling method is carried out using subtractive clustering, and parameter identification is conducted via some heuristics as well as an optimization problem. Furthermore, a simulation method along with some heuristic relations is used for implementation and evaluation of the modified model. Efficiency of the proposed method to fuzzy modeling as well as the proposed simulation method is presented by a numerical example. [less ▲]

Cobalt-Mediated Radical Polymerization (CMRP) is an efficient tool for polymerizing acrylates and vinyl esters. However, a challenge in CMRP remains in controlling the polymerization of both types of monomers with the same cobalt complex. Here, we show how Co(acac)2, efficient for unconjugated vinyl monomers, can also cope with acrylates. [less ▲]

Skin contains somatic stem cells that generate keratinocyte, melanocyte and mesenchymal cell lineages. These somatic stem cells have traditionally been thought to be restricted in their differentiation and regeneration potential to the tissues in which they reside. This review focused on epidermal stem cells (ESCs). These cells are distinguished from transitory amplifier cells and post-mitotic cells. ESC are found in the interadnexal epidermis and in the bulge region of hair follicles. A series of ESCs markers are available, but increased sensitivity and specificity require further development.

Background: Sweating is variably altered by physical exercise, diabetic neuropathy and antiperspirants. Methods: Skin temperature, skin surface water loss (SSWL), the Corneometer((R)) average capacitance (CMAC) and skin capacitance mapping (SCM) were measured before and after moderate physical exercise in 20 healthy subjects. The effect of 5% aluminium chloride hexahydrate (ACH) in a water solution was similarly tested. The same assessments were performed in 20 diabetic patients at rest. Results: Diabetic neuropathy appeared at rest as an increased (compensatory) SCM on the forearms without obvious modification on the hypohidrotic legs. On ACH sites after exercise, SCM revealed both a lowered number of active sweat glands and a lighter stratum corneum (SC) (dryness). In addition, CMAC and SSWL were decreased on ACH sites at rest and at completion of exercise. Conclusion: In diabetic neuropathy, the compensatory hyperhidrosis is more easily disclosed than the hypohidrosis. ACH affects both sweat excretion and the SC hydration. [less ▲]

Facio-craniostenosis. Facio-craniostenosis is associated with premature stenosis of one or several cranial sutures. The clinical variety is defined by the affected suture. In the complex forms, major disturbances of the anterior fossa of the cranial base are observed. Intracranial hypertension sometimes observed may lead to impairment of the function of the brain or the eyes. The authors have observed 73 children with craniostenosis and have operated upon 49 of them. Three types of methods have been used. The stress is made on the latest one combining advancement of the orbito-frontal "bandeau" and the regularization of the vault. Operating early is essential for prevention of functional sequellae. The optimal age for surgical treatment seems to be between 3 and 6 months. Complications have been remarkable benign. [less ▲]

Invadopodia are proteolytically active membrane protrusions that extend from the ventral surface of invasive tumoral cells grown on an extracellular matrix (ECM). The core machinery controlling invadopodia biogenesis is regulated by the Rho GTPase Cdc42. To understand the upstream events regulating invadopodia biogenesis, we investigated the role of Fgd1, a Cdc42-specific guanine nucleotide exchange factor. Loss of Fgd1 causes the rare inherited human developmental disease faciogenital dysplasia. Here, we show that Fgd1 is required for invadopodia biogenesis and ECM degradation in an invasive cell model and functions by modulation of Cdc42 activation. We also find that Fgd1 is expressed in human prostate and breast cancer as opposed to normal tissue and that expression levels matched tumor aggressiveness. Our findings suggest a central role for Fgd1 in the focal degradation of the ECM in vitro and, for the first time, show a connection between Fgd1 and cancer progression, proposing that it might function during tumorigenesis.

L’Organisation mondiale de la santé (OMS) recommande un allaitement maternel exclusif jusqu’à six mois et un allaitement partiel jusqu’à deux ans ou au-delà. En Europe actuellement, il existe de fortes disparités de prévalence de l’allaitement selon les pays. L’objectif de cet article est de faire le point sur les facteurs associés à un allaitement maternel prolongé au-delà de trois mois. Les études permettent d’identifier différents niveaux de facteurs qui interagissent, selon un cadre écosystémique incluant la mère et son bébé (microsystème), l’entourage (mésosystème), le système de santé (exosystème) et les politiques de santé (macrosystème). Afin d’atteindre les objectifs recommandés par l’OMS, il est important de mettre en place des actions à tous les niveaux. L’information aux mères doit être renforcée, de même que l’implication des pères et la formation des professionnels de santé. Après la sortie de maternité, il est primordial que les mères présentant des facteurs de risque de sevrage précoce soient soutenues si on veut que l’allaitement se poursuive. [less ▲]
