Bacterias lácticas de "Sheep's Dhan", una mantequilla tradicional: aislamiento, identificación y principales aspectos tecnológicos

Twenty six lactic acid bacteria were isolated from sheep’s Dhan, a traditional butter made from sheep’s milk in Jijel (East of Algeria). These strains belong to three genera: Lactococcus, Leuconostoc and Lactobacillus. The results showed that Lactococcus lactis ssp diacetylactis was the predominant species in this traditional butter. The results of the assessment of the technological aptitude indicate that a major strain has a good acidification aptitude, some of them show good proteolytic activity and only Leuconostoc mesenteroides ssp. dextranicum isolates were able to produce exopolysaccharide.Veintiséis bacterias lácticas fueron aisladas de “Sheep´s Dhan”, una mantequilla tradicional hecha con leche de oveja en Jijel (al Este de Argelia).

Optimisation des performances et de la consommation de puissance électrique pour architecture Intel ltanium/EPIC

This thesis proposes, in its first part, to extend the EPIC architecture of the Itanium processor family by providing a hardware stack. The principal idea defended here is that it is possible to close the existing performance gap between generic architectures and application specific designs to run virtual machines (FORTH, .NET, Java, etc). With this intention, we propose to reallocate dynamically a subset of the EPIC architecture’s resources to implement a hardware evaluation stack. Two implementations are proposed, both non-intrusive and compatible with existing binary codes. The fundamental difference between these stacks lies in their manager: software or hardware. The hardware controlled evaluation stack offers support for advanced functions such as the support of strongly typed evaluation stacks required by .NET’s CIL. Thus, we propose a single pass CIL binary translator into EPIC binary, using the hardware evaluation stack. In the second part of this thesis, we studied the energy efficiency of software applications. First, we defined a methodology and developed tools to measure the energy consumption and the useful work provided by the software. In a second time, we engaged the study of source code transformation rules in order to reduce/control the quantity of consumed energy by the software.Cette thèse propose, dans sa première partie, d’étendre l’architecture EPIC des processeurs de la famille Itanium par l’ajout d’une pile matérielle. L’idée principale est qu’il est possible de combler l’écart de performance entre une architecture généraliste et les circuits spécialisés pour exécuter des machines virtuelles (FORTH, .NET, Java, etc.). Pour ce faire nous proposons de réassigner dynamiquement un sous-ensemble des ressources existantes d’EPIC pour offrir une pile d’évaluation matérielle. Deux implémentations, non-intrusives et respectant la compatibilité binaire des applications existantes, sont proposées. La principale différence entre ces piles réside dans leur gestionnaire: logiciel ou matériel. La pile d’évaluation sous le contrôle du matériel présente des fonctions avancées comme le support des piles d’évaluation typées promues par la CIL de .NET. Ainsi, nous proposons un traducteur simple-passe de binaire CIL en binaire EPIC, utilisant la pile d’évaluation matérielle. Dans la seconde partie de cette thèse, nous avons étudié l’efficacité énergétique des applications sur les architectures Intel. Nous avons ainsi défini dans un premier temps une méthodologie et des outils de mesure de l’énergie consommée et la quantité de travail utile fournie par les logiciels. Dans un second temps, nous avons entamé l’étude de transformations de code source afin de réduire / contrôler la quantité d’énergie consommée par les logiciels

Naturally fermented Jijelian black olives: microbiological characteristics and isolation of lactic acid bacteria

A study of the microflora of traditionally fermented black olives in Eastern Algeria is presented. A count of the following microbial groups was carried out: mesophilic bacteria, enterobacteria, lactic acid bacteria (LAB), staphylococci and yeast. In a second phase, the identification and assessment of the technological traits of LAB was performed. Seventeen lactic acid bacteria were isolated and identified. These isolates were represented by two genera: <i>Lactobacillus</i> and <i>Leuconostoc</i>. The results showed that <i>Lactobacillus plantarum</i> was the predominant species in this traditional product.<br><br>Un estudio sobre la microflora de aceitunas negras fermentada por métodos tradicionales en el Este de Argelia es presentado.

Expanding the genetic and phenotypic relevance of KCNB1 variants in developmental and epileptic encephalopathies: 27 new patients and overview of the literature

Developmental and epilepsy spectrum of KCNB1 encephalopathy with long-term outcome.

OBJECTIVE: We aimed to delineate the phenotypic spectrum and long-term outcome of individuals with KCNB1 encephalopathy. METHODS: We collected genetic, clinical, electroencephalographic, and imaging data of individuals with KCNB1 pathogenic variants recruited through an international collaboration, with the support of the family association "KCNB1 France." Patients were classified as having developmental and epileptic encephalopathy (DEE) or developmental encephalopathy (DE). In addition, we reviewed published cases and provided the long-term outcome in patients older than 12 years from our series and from literature. RESULTS: Our series included 36 patients (21 males, median age = 10 years, range = 1.6 months-34 years). Twenty patients (56%) had DEE with infantile onset seizures (seizure onset = 10 months, range = 10 days-3.5 years), whereas 16 (33%) had DE with late onset epilepsy in 10 (seizure onset = 5 years, range = 18 months-25 years) and without epilepsy in six. Cognitive impairment was more severe in individuals with DEE compared to those with DE. Analysis of 73 individuals with KCNB1 pathogenic variants (36 from our series and 37 published individuals in nine reports) showed developmental delay in all with severe to profound intellectual disability in 67% (n = 41/61) and autistic features in 56% (n = 32/57). Long-term outcome in 22 individuals older than 12 years (14 in our series and eight published individuals) showed poor cognitive, psychiatric, and behavioral outcome. Epilepsy course was variable. Missense variants were associated with more frequent and more severe epilepsy compared to truncating variants. SIGNIFICANCE: Our study describes the phenotypic spectrum of KCNB1 encephalopathy, which varies from severe DEE to DE with or without epilepsy. Although cognitive impairment is worse in patients with DEE, long-term outcome is poor for most and missense variants are associated with more severe epilepsy outcome. Further understanding of disease mechanisms should facilitate the development of targeted therapies, much needed to improve the neurodevelopmental prognosis
