This practical course aims to apply students' knowledge of microbiology and molecular biology to the identification of environmental bacteria.

Quantitative and qualitative analysis of the bacterial population present in a soil sample is classically done by identifying species using conventional bacteriological methods in successive stages: 1) isolation of bacterial flora; 2) diagnosis of family and genus using conventional media and tests; 3) diagnosis of species using API System galleries.

Molecular biology techniques now make it possible to identify the bacteria present in a sample without the need for cultivation. This approach requires access to a sequencing platform and will also be carried out as part of the practical work, enabling the two approaches to be compared. The sequencing results obtained will enable bioinformatic analysis of the rrsA gene specifying the RNA16S of isolated bacteria.

This course describes the methodology used by life science researchers to communicate the results of their experiments, both orally and in writing. As English is the common language of international researchers, a large part of this course is taught in this language.

Written communication is addressed through the study of the (macro) structuring of a research article, as well as through a study of the publication process in scientific journals. Several elements of written structuring (micro) are examined in order to understand the differences between scientific and literary English: clarity, cohesion, coherence.

These studies are supplemented by a tutored project during the semester, during which students analyze a research article recently published in the scientific literature and transcribe it into an oral presentation (conference) in English.

Molecular biology is a fascinating subject of study in its own right, but it also provides other disciplines in biology (cell biology, genetics, physiology...) with fantastic tools for modifying and quantifying genes and their products.

The EU provides a deeper understanding of the mechanisms of organization, maintenance, replication and expression (transcription, post-transcriptional modifications, translation) of eukaryotic genomes.

In particular, we'll be exploring the properties of information-carrying macromolecules (DNA, RNA, proteins), and how transactions between them explain how eukaryotic cells function and adapt to the environment and to the development of organisms.

At the same time, the main techniques for monitoring or modifying gene expression, or for studying the mechanisms of this expression, will be explained in class and analyzed in greater depth in practical sessions.

TDs will address these topics in the form of (1) exercises enabling students to check their understanding of the knowledge described above, and (2) experiments extracted from scientific articles to be analyzed. In this way, the fundamentals of scientific reasoning and the critical analysis of results are acquired and/or deepened.

Bioinformatics is a discipline at the crossroads of computer science, mathematics and the life sciences. It is based in particular on the use and development of computer tools for the analysis of massive biological data. Eventually, these megadata can be organized into searchable online databases, enabling users to extract data relevant to a biological problem.

The aim of the "Bioinformatics applied to plant biology" teaching unit is to introduce students to the use of databases and to offer a first approach to data mining using R software.

Virtually all teaching will take the form of practical case studies in the computer room, in student sub-groups.

In the first part, students will learn the rudiments of the R computer language, enabling them to organize and clean up their raw data to make it fully exploitable for further analysis. They will then learn how to propose explicit graphical representations based on biological data. Particular attention will be paid to writing reusable scripts and choosing the graphics associated with the calculations according to the biological question at hand.

In the second part, students will use general databases such as NCBI, or databases devoted exclusively to the model plant Arabidopsis (TAIR), to carry out data mining.

This course is an extension of the "Fundamentals of Evolution" course, and introduces the main concepts of evolutionary ecology in order to understand and formalize in a simple way the evolutionary and ecological mechanisms that shape biodiversity at different scales of integration.

This course is designed as a coherent whole, with lectures, tutorials and practical work complementing each other. Notions are approached by example, then formalized using mathematical models, which are compared with experience and real data.

It will deal with population dynamics (intra- and interspecific competition), ecological niches and will detail the mechanisms of evolution and their genetic consequences on a population scale: natural selection (including sexual selection), influence of reproductive regimes, genetic drift. The practical sessions will enable students to master the mathematical formalization of notions seen in class and their simple computer modeling, as well as the analysis of data sets. Practical work will enable students to carry out and analyze in small groups 2 experiments lasting 1 month each (with report writing and oral presentation), in order to develop methodology and scientific reasoning.

This course is a natural continuation of the " Quantifying Hazards " course (HAV424B) presented in S4. It should provide the concepts for constructing experimental protocols that answer biological questions, and for associating appropriate models for analyzing variability. The first part will be devoted to the construction of experimental protocols that can answer a multitude of questions in the life sciences, i.e. taking into account the inevitable dependence of statistical individuals, such as pairing and the spatial or temporal structure of populations. This part of the course will also introduce the notion of fluctuation, replication and pseudo-replication, which will be taken into account in the models built in the second part of the course. The second part of the course will show the link between the experimental protocol and the modeling of the variability of a quantitative response variable, through the construction of models including several qualitative or quantitative variables. Particular attention will be paid to the conditions of application of these methods, to type I and type II errors, to methods for estimating the parameters of the models constructed (including likelihood) and to the interpretation of the estimated parameters. Each notion will be illustrated by the analysis of real biological data from a variety of themes, helping students to discover not only modern and current biological questions, but also the tools developed to answer them. Practical work in R will enable students to independently carry out analyses on published biological cases.

The course provides an overview of the concepts required for mathematical modeling in biology. The focus is on linear and non-linear dynamical systems, in dimension one and two. The course begins with essential notions of linear algebra: matrices, systems of linear equations, geometric interpretation of the solutions of these systems as vectors and subspaces (line, plane, etc.). The theory of vectors and eigenvalues of matrices is introduced in relation to linear dynamical systems. For non-linear dynamical systems, the qualitative theory of differential equations (attractors, phase portraits, zero-level isoclines) is presented, as an alternative to the often complicated calculation of solutions. The TD covers a wide range of biological models used in ecology, epidemiology, oncology and systems biology.

This course enables students to consolidate and deepen their practical management of numerous experimental data obtained over a week of practical work during a blocked period (5 consecutive days). These data are obtained following the elaboration of many different protocols, keeping in mind to ensure the best reproducibility of the preparations carried out and to have the best speed of execution in the preparation, realization and analysis of the different experiments. A high degree of autonomy in setting up protocols will be encouraged, leading ultimately to experimental mastery and autonomy. This practical work will also enable students to work in groups (in pairs or trios, depending on capacity and number of students), and to write a report recording the protocols carried out, all the experimental data obtained and their analysis, in order to determine a wide range of biochemical parameters. A significant part of the assessment will be based on the students' ability to generate, manage, exploit and analyze raw experimental data with the utmost rigor.

Bacteriology :

Through various examples, students will gain a better understanding of the notion of pathogenicity in relation to bacterial virulence. The means and mechanisms used to manipulate the organism's cells at mucosal level in order to penetrate the internal environment, i.e. invasiveness, will be discussed, as well as the perception of environmental signals and the integration of these signals in order to coordinate the response of prokaryotes so that they adopt group behavior. The description of some examples of toxins and modulins in relation to colonization and/or invasion will provide a better understanding of the differences in strategies between prokaryotic pathogens. Finally, we'll look at the notion of the microbiota and its influence on the functioning of the organism, as well as its implication in the development of certain pathologies.

Immunology:

The Immunology section outlines the workings of the immune system during infection. From the establishment and development of the inflammatory reaction upon recognition of non-self signals by natural immunity (PRR-PAMP), to the mechanisms of cell activation and the cellular responses generated, we can appreciate the diversity of possibilities offered by the different players in the immune system. In addition, the sequence of events leading to the orientation of the immune response and the acquisition of lasting protection during the adaptive phase will provide a better understanding of vaccine strategy. Finally, immunity of the intestinal mucosa will be addressed in the context of the relationship between the host and the microbiota.

Universities are often perceived as inaccessible places for large sections of society. As part of the UniverlaCité program, which aims to bring the university to life in disadvantaged neighborhoods, the students will be setting up scientific workshops for schoolchildren in disadvantaged areas. 

The EU will offer students the opportunity to :

1- share their own experiences and enhance the value of the knowledge they have acquired at the University, with a view to responding as effectively as possible to the needs of society.

2- Reveal and develop scientific communication skills through the design and production of teaching aids adapted to the target audience.

The course will take the form of tutorials and project follow-up (SPS) on pre-defined themes. The socio-cultural situation of sensitive urban areas will be addressed in the first class. This first TD will also serve to lay the foundations for the UE, present the UniverlaCité system in detail and give a broad overview of scientific mediation.

The following TDs will serve as sessions during which students, divided into groups, will have to propose activities to be set up. The constraints given to them by the teaching team will be: the target audience, the theme (which will be defined by the teaching team and renewed each year) and the need to propose activities "outside the classroom".

They will be approached both from the point of view of their structure and from the point of view of their functioning, emphasizing both their similarities and their differences, and the abiotic and biotic factors that govern the organization of the communities of organisms that inhabit them.

They should provide an overview of these ecosystems or hydrosystems and how they function at different scales.

The first part of the course is devoted entirely to theory, while the second includes introductory sessions for field trips, the field trips themselves and practical sessions for analyzing and pooling the data collected in the field.

Molecular tools are an integral part of studies aimed at describing and characterizing biodiversity. The aim of the course is to present various molecular approaches (barcoding, metabarcoding and environmental DNA, etc.) for (1) describing, characterizing and quantifying this diversity at intra- or interspecific, population or ecosystem levels, and (2) presenting their fields of application at different scales of time and space. The course will include practical aspects aimed at familiarizing students with these techniques, implementing them, analyzing the resulting data and reporting on them. Priority will be given to group work in interaction with researchers and teacher-researchers.

ORPAL is an APP ecology course (1/3 fieldwork and 2/3 laboratory work). Based on Ecology concepts and methods, this course aims to introduce students to historical ecology (the study of interactions between man and his environment over variable chronological periods) and its main applications in paleoecology, from problem definition, field sampling and data acquisition to interpretation and the writing of a scientific article (see https://biologie-e cologie.com/exemples-travaux/). This course is an interesting theoretical and experimental prerequisite for the ACCES, CEPAGE, PALEONTOLOGY, ECOSYSTEMS or BIOGET courses.

Adaptations to the "parasitic" lifestyle are studied on all parasitic organisms (viruses, bacteria, eukaryotes), including different scales of analysis "from molecules to populations".

Thus, the coevolution between hosts and parasites will be considered from the point of view of host-parasite molecular and cellular dialogues (immunity-escapement-exploitation of host resources, etc.), but also from the point of view of morpho-anatomical structures involved in adaptation to the sub-host site or in survival in the external environment, and finally from the point of view of behavioral adaptations for encountering the host (promotion).

One of the aims of this course is to synthesize notions and knowledge acquired in animal biology (anatomy, systematics) and ecology to describe and understand the morphology and evolution of vertebrate morphologies. In addition to present-day groups, this course will focus on extinct fossil groups, in particular their contribution to understanding the various eco-morphological adaptations (e.g. acquisition or return to aquatic life, acquisition of flight) that have marked the evolutionary history of clades.

This course also aims to provide a theoretical and practical grounding in phylogeny (cladistics) for tracing the evolution of a clade (distance, parsimony and likelihood methods), both for molecular and phenotypic traits (present-day and fossil).

Introduce students to an integrated approach to plants by studying the morpho-anatomical characteristics of stems and roots. They will discover the spatio-temporal coordinated construction of root and stem architectures through adaptations of Mediterranean and tropical species. Reproductive structures and the diversity of biological types will also be taken into account. This course is designed to prepare students for a Master's degree in BioGET, and is based on the natural environment and local and regional infrastructures (Serre Amazonienne, Villa Thuret, Jardin Château La Pérouse).

The mechanism of action of drugs is based on interaction with a target cell structure in the body, leading to modulation of its function. This course is divided into 2 main parts. The^1st part will introduce students to the different modes of cellular communication, the different chemical messengers, their targets and their modes of action. The 2nd part will give students a basic understanding of pharmacology, i.e. how drugs work and what happens to them in the body. To this end, the concepts of pharmacodynamics (ligand-receptor interaction, effect-dose relationship) and pharmacokinetics (ADME: absorption-distribution-metabolism-excretion) will be covered. Drug targets, intracellular signaling and therapeutic indications will also be covered.

The EU provides an introduction to the main diseases affecting the nervous system, both neurological and psychiatric. Pathologies are treated from a multidisciplinary angle, from the molecular to the symptomatic. This basic knowledge of neuropathology will serve as a foundation for the fields of research addressed later in the Master's program.

The Sensory and Motor Neurophysiology course covers the anatomical and functional organization of the main sensory systems: vision, hearing and somesthesia. On the other hand, it deals with motricity and its central control at the spinal and supra-spinal levels: brain stem, motor cortex, cerebellum and basal ganglia.

The aim of this course is to provide students with fundamental and in-depth knowledge and skills in the physiology of the endocrine system. By studying the morphological and functional organization of the endocrine system, the student will be able to grasp the multitude of hormonal systems (endocrine glands, hypothalamo-hypophyseal axis, reproductive system) and their essential roles in the realization of major physiological functions and homeostasis.
