Delta-cd20: new biomarker for diagnosis applications

The EFS inventors established a novel CD20 alternative mRNA coding for truncated protein of 15-17 Kda (DELTA-CD20) lacking large parts of the transmembrane segments. This protein is expressed at various levels in malignancies B-cells and is absent in normal B cells isolated from healthy donors. This data show that truncated protein CD20 could be used as a molecular marker for diagnosis, prognostic and monitoring B-cell malignant diseases. Moreover the EFS inventors show that DELTA-CD20 expression is associated to RTX resistance. DELTA-CD20 protein is a potential target for treatment of B-cell lymphoproliferative disorders.

Assessment of malignancy and prediction of efficacy of treatment of tumours

The proposed solution is an objective method for prognosis of a cancer based on the analysis of a virtual slide (from a solid tumour specimen) by a software program. Using a machine learning algorithm, 3 patterns emerged from linear quantification of lymphocytes of 117 patients. For example, the relative risk of relapse at 5 years is 16 if you have the pattern 3 (compared to the pattern 1). This technique is more reliable and more rapid than current ones and rounds out the present anatomicopathology methods to clarify the prognosis derived from the TNM classification. It will enable the assessment of the risk of postoperative recurrence, sensitivity to the various anti-tumour treatments and also the risk for metastases to develop

Utilisation du cannabis médical (sativex®) dans la dégénérescence neuronale de l’oesophage (achalasie)

L’achalasie est une dégénérescence inflammatoire neuronale causant des troubles de la motilité de l’oesophage (dysphagie, régurgitations, perte de poids importante). Aucun traitement médicamenteux (myorelaxants) n’a prouvé son efficacité et les alternatives thérapeutiques sont invasives et peu efficaces. Nous proposons une nouvelle indication pour le cannabis médical (Sativex ®) dans la gestion des symptômes physiques de l’achalasie. En effet, il a des propriétés pharmacologiques anti-spastiques qui pourraient améliorer la relaxation du sphincter inférieur de l’oesophage à la déglutition.

Ciseaux de fenestration endovasculaires

La dissection de l’aorte thoraco-abdominale est une pathologie grave, engageant le pronostic vital des patients à court et long terme. L’incidence est d’environ 1% avec un taux de mortalité de 50% dans les 48 premières heures. Elle se caractérise par une déchirure au niveau de la paroi interne de l’aorte permettant au sang de s’engouffrer entre les feuillets superposés constituant cette paroi, ce qui conduit à la formation d’un 2ème chenal, parallèle à la lumière de l’aorte. Parfois, une seconde déchirure, éloignée de la première permet au sang de ressortir et de rejoindre le vrai chenal (aorte). Il en résulte une mauvaise perfusion des artères irriguant les organes et les membres inférieurs. Les stratégies thérapeutiques mises en œuvre visent soit à fermer la brèche en introduisant une endoprothèse, soit à déchirer le « flap » séparant les deux chenaux. Cette 2ème technique est appelée fenestration. Le recours à ces techniques se révèle parfois impossible (existence d’autres portes d’entrée, rigidification du « flap » suite au développement d’un tissu fibreux cicatriciel…) ou imprécis (le geste de la fenestration est peu maîtrisé par le praticien qui travaille, malgré le suivi radioscopique, « à l’aveugle »). Il est donc nécessaire de proposer un dispositif permettant d’élargir les indications des actes de chirurgie endovasculaire.

New biodegradable anti-migration intestinal stent

In the US, nearly 1,5 million patients suffer from Crohn’s disease. The most common complication is digestive stenosis (50% of patients). If the stenosis measures less than 5 centimeters, an endoscopic dilatation is possible. However, it is associated with relapse rates of 30 to 50 % at 1-3 years. In this case, the patient undergoes another endoscopic dilatation or sometimes a bowel resection. The use of covered expandable metallic prostheses (used for malignant obstructions) could enhance the long-term efficacy of endoscopic dilatation. However, this solution is currently not possible, due to a high rate of uncontrolled migration (30 to 80% of cases). Our solution is a new stent with an original anti-migration design.

Device for measuring the length of a stenosis

Inflammatory bowel diseases (Crohn’s disease and ulcerative colitis) affect around 1.6 million Americans and represent a sales market worth $5.6 billion worldwide. Intestinal inflammation often results in stenosis, for which a classic treatment is surgical resection. However, surgical resection is a drastic option ; if the stenosis is located on a zone accessible to endoscopy, it can be treated alternatively by dilatation, using an endoscope coupled with a balloon catheter. This method can be inefficient if the stenosis is too long. Therefore, measuring the length of the stenosis prior to dilatation is crucial for choosing the most appropriate shape and dimensions of the balloon. Another treatment is a stent placement that also requires measuring the length of the stenosis so as to choose a well-suited stent. Currently, measurements of stenosis length is often inaccurate and result in inappropriate dimensions of the balloon catheter or the stent. We propose a new endoscopic medical device for measuring precisely the length of a stenosis in inflammatory bowel diseases.

Method for increasing the pool of ngn3+ endocrine progenitor cells and pancreatic endocrine cell mass

Controlling glycemia with insulinotherapy is a challenge that diabetic patients face every day. Moreover, insulinotherapy is not a curative therapy by any means. This line of treatment is only palliative and presents many limitations for the fine control of blood sugar levels. Uncontrolled blood sugar levels can result in serious damages to the eyes, nerves and kidneys of diabetic patients. However, pancreatic islets transplantation provides an alternative therapeutic option that would make perfect control of glycemia possible. As such, pancreatic cell therapy is an appropriate and effective solution for the treatment of type 1 diabetes. The technology relies on the ability of K-ATP channels to regulate the secretion of insulin and the differentiation of α and β pancreatic cell. The technology is a method of cell therapy that involves in vitro stem cell differentiation into endocrine pancreatic cells. The stem cell differentiation is triggered by glibenclamide, a K-ATP channel inhibitor.

Enabeling/facilitating trans-cutaneous delivery of active material

Efficient trans-cutaneous delivery of active molecules is still a challenge due to the nature itself of the dermal tissue. The permeabibility of therapeutic agents can be improved by permeability agents but most of the induced delivery mechanisms induce irreversible skin alterations. We present here an original strategy consisting in using the active molecule itself to parcicipate into ist own trans-cutaneous transport, while protecting solubilizing and delivering it to its active site.

Natural compounds activating sirt1 for the cellulite treatment

The sirtuin family concerns nuclear NAD+ dependant deacetylases, playing an important role in deacetylation of histones. Sirtuin 1 is the best known situin. It is involved in an important number of metabolic processes. It has several target as p53, FoxO, PPAR gamma, PGC1 alpha, UCP2, LXR and Ku70, key regulating proteins in cell functions. Sirt1 has a global anti-aging effect. The Sirt1 expression decreases along the lifetime. Sirt1 has also a role in adipogenesis and lipid accumaltions. The lipolysis is increased by activating Sirt1 activity.

Low energy consumption backery oven

Bread baking requires a large quantity of energy – roughly 2 to 5 Mjoules /kg that is 2 to 3 times higher than the energy required for the same mass of a food product in the form of canned food for example. Furthermore food habits are changing in the world : we see in most European countries a decreasing consumption of bakery products at home while the consumption of bakery products outside home increases significantly. This market trend is supported by specific technologies such as partial baking of bread which are refreshed (second baking) in baking stations or in restaurants. There is thus a need to develop low energy demanding equipments.

Compounds for the treatment of mitochondrial diseases

The present invention relates to the isolation and development of drugs to treat mitochondrial pathologies involving a deficiency in ATP production via the oxidative phosphorylation pathway, such as NARP syndrome. NARP (Neuropathy, Ataxia and Retinitis Pigmentosa) is a maternally transmitted hereditary syndrome characterized by retarded development, and accompanied by retinitis pigmentosa (RP), dementia, ataxia, proximal neurological muscle weakness and sensory neuropathies. The clinical manifestations are varied and can take more or less severe forms. Thus, the ophthalmic manifestations can range from a simple "salt and pepper" changing of the retina to severe RP, accompanied by maculopathy. Similarly, there is a broad 15 spectrum of neurological manifestations, which ranges from simple migraines to severe dementia and to "Leigh's disease". Many retinitis pigmentosa related syndromes exist, such as Usher's syndrome in which both the sight and the hearing are affected, or else macular dystrophy, also called inverse RP.

Protein involved in dna replication, and modulation of its activity

Although DNA replication is a vital process for cell growth and its mechanism is highly conserved, recent studies also reveal significant diversity in origin structure, assembly of pre-replication complex (pre-RC) and regulation of replication initiation along evolutionary lines. It is crucial to maintain genomic integrity in eukaryotic cells. During DNA replication, errors in pre-RC assembly often result in substantial changes in the amount of genetic material, which will cause cell death, or transform cells to become malignant tumors. The first origin recognition complex (ORC) proteins were purified from cell extracts as a heterohexameric complex that specifically binds to origins of DNA replication and the subunits were named Orc1 through Orc6.

One step in-situ graphene oxide reduction in composite

It is well known that electrical or thermal properties of graphene are of importance in composites for applications like anti-static composites, biomedical, organic electronics, sensors… but the mixing of graphene in polymers is not easy. It has thus been proposed to mix graphene oxide (GO), a graphene derivative which by contrast to neat graphene can be easily processed, with the organic matrix and then to reduce it. This reduction step is performed to restore, at least partially, the properties of graphene. It has a critical influence on the properties of the final material. One reduction route is to heat the composite in order to reduce the GO in rGO but the maximum temperature is limited due to the organic matrix. Other ways like exposition to hydrazine hydrate at 100°C 24h, H2 plasma or IR xenon flash lamp have been proposed. Each of these having detrimental influence on the final composite and none of these allowing to efficiently restore the graphene properties.

Epitaxie dans un réacteur pecvd standard a basse température (200°c)

Les procédés de fabrication de couches minces pour les dépôts grande surface et la réalisation des composants pour la microélectronique ont suivi des voies très différentes jusqu’à présent. Pour les semi-conducteurs, les matériaux doivent généralement être cristallins, le plus parfaits possible; leurs procédés de fabrication nécessitent souvent des conditions expérimentales extrêmes : un vide poussé (~10-8–10-10 mbar) en MBE, et des températures élevées (600 - 800 °C) en MOCVD ; ils sont donc plutôt couteux. Au contraire, l’électronique grande surface (écrans plats par exemple) s’est développée grâce aux procédés de dépôt de couches minces de silicium amorphe produites à plus basse température (200 °C) en présence d’un plasma (PECVD) sur de plus grandes surfaces (~m2). Est-ce possible de réconcilier aujourd’hui les deux voies de production de couches minces et leur qualité. Peut-on produire des films de matériaux cristallins au prix des matériaux amorphes ?
