Nouvelles stratégies innovantes en immunothérapie

2018

Resume Les progres recents de l’immunotherapie en oncologie avec le developpement des anticorps anti-PD1/PD-L1 revolutionnent la prise en charge oncologique. L’immuno-oncologie se developpe ainsi dans la plupart des types histologiques de cancer. Malgre tout, l’utilisation des anticorps anti-PD1/PD-L1 en monotherapie est limitee par une reponse restreinte a une sous-population de malades representant environ 25-30 % des patients dans la plupart des indications. Le developpement de nouvelles strategies se base sur cette observation. Ainsi on note le developpement de differentes strategies ayant pour objectifs de mieux selectionner les malades ou de combiner les checkpoints inhibiteurs avec d…

TORC1 controls G1–S cell cycle transition in yeast via Mpk1 and the greatwall kinase pathway

2015

The target of rapamycin complex 1 (TORC1) pathway couples nutrient, energy and hormonal signals with eukaryotic cell growth and division. In yeast, TORC1 coordinates growth with G1–S cell cycle progression, also coined as START, by favouring the expression of G1 cyclins that activate cyclin-dependent protein kinases (CDKs) and by destabilizing the CDK inhibitor Sic1. Following TORC1 downregulation by rapamycin treatment or nutrient limitation, clearance of G1 cyclins and C-terminal phosphorylation of Sic1 by unknown protein kinases are both required for Sic1 to escape ubiquitin-dependent proteolysis prompted by its flagging via the SCFCdc4 (Skp1/Cul1/F-box protein) ubiquitin ligase complex.…

Blackwood's Magazine - "Nodier's Promenade"

2013

We have translated and annotated an extended review from "Blackwood's Edinburgh Magazine" reporting on the publication, in English translation, of "Promenade de Dieppe aux montagnes d'Écosse" by Charles Nodier ("Promenade from Dieppe to the Mountains of Scotland", Edinburg, Blackwood, London, Cadell, 1822). The reference of the original article is as follows: "Nodier's Promenade", Blackwood's Edinburgh Magazine", march 1822, vol. XI (January - June 1822).

Glucose regulation and pain in older people-The Helsinki Birth Cohort Study

2021

Aims: To assess if individuals with diabetes or prediabetes report more pain or have increased use of pain medication compared to normoglycaemic individuals. Methods: Using cross-sectional data, we studied 928 men and 1075 women from the Helsinki Birth Cohort Study in 2001-2004 at a mean age of 61.5 years. Glucose regulation was assessed with a 2-h 75 g oral glucose tolerance test, and applying World Health Organization criteria, participants were defined as having normoglycaemia, prediabetes (impaired fasting glucose or impaired glucose tolerance), newly diagnosed diabetes or previously diagnosed diabetes. Self-reported pain intensity and interference during the previous 4 weeks was estima…

Noncontact speckle-based optical sensor for detection of glucose concentration using magneto-optic effect

2016

We experimentally verify a speckle-based technique for noncontact measurement of glucose concentration in the bloodstream. The final device is intended to be a single wristwatch-style device containing a laser, a camera, and an alternating current (ac) electromagnet generated by a solenoid. The experiments presented are performed in vitro as proof of the concept. When a glucose substance is inserted into a solenoid generating an ac magnetic field, it exhibits Faraday rotation, which affects the temporal changes of the secondary speckle pattern distributions. The temporal frequency resulting from the ac magnetic field was found to have a lock-in amplification role, which increased the observ…

Use of fasting blood to assess the prevalence of insulin resistance in women with polycystic ovary syndrome

2003

To determine the prevalence of insulin resistance (IR) in women with polycystic ovary syndrome (PCOS) using baseline fasting blood measurements of glucose and insulin. Prospective clinical study. Academic endocrinology unit in Palermo, Italy. Two hundred and sixty-seven women with PCOS, consecutively evaluated, and 50 consecutively selected ovulating controls. Fasting blood was obtained for glucose and insulin measurements from all women. For 60 women with PCOS and 20 controls an insulin tolerance test (ITT) was also performed. Assessment of normal and abnormal values for fasting insulin, glucose/insulin ratio, and the calculated indices of the homeostasis model assessment (HOMA), quantitat…

Intraoral onlay block bone grafts versus cortical tenting technique on alveolar ridge augmentations: a systematic review

2021

To review systematically the bone gain and superficial resorption rate of the onlay block bone grafts versus the cortical tenting technique, as well as secondarily study the postoperative complications, implant survival and success rates, and peri-implant marginal bone loss. Following the recommended methods for systematic reviews and meta-analyses (PRISMA), an electronic search was performed in the PubMed (MEDLINE), EMBASE and the Cochrane Library of the Cochrane Collaboration (CENTRAL) databases to identify all relevant articles published up to March 2021 on onlay block bone grafts and cortical tenting technique. Eighteen papers complied with the inclusion criteria. In onlay grafts, the v…

Disc degeneration and bone density in monozygotic twins discordant for insulin-dependent diabetes mellitus

2000

The effects of insulin-dependent diabetes mellitus on bone density and connective tissue degeneration have theoretical interest and practical relevance. Several experimental studies in animals have demonstrated the harmful effects of insulin deficiency on connective tissues. However, clinical studies in humans have produced somewhat contradictory results, most likely due to difficulties controlling for general degeneration and factors associated with diabetes. In nine pairs of monozygotic twins discordant for insulin-dependent diabetes mellitus, we compared femoral and lumbar bone mineral density (assessed by dual-energy x-ray absorptiometry) and spinal degeneration (assessed by magnetic re…

2020

This study aimed to investigate the associations of competitive sport participation in adolescence and age at menarche (AAM) with body composition, femoral neck bone mineral density (BMD), physical performance, and physical activity (PA) in middle-aged women. 1098 women aged 47–55 years formed the sample of this retrospective study. Participants self-reported their PA level at age 13–16 years and AAM. The protocol also included dual-energy X-ray absorptiometry, physical performance tests, and accelerometer-measured PA. Participants were divided into three groups according to their PA level at the age of 13–16 (no exercise, regular PA, and competitive sport) and according to their AAM (≤12, …

Preclinical evaluation of antitumor activity of the proteasome inhibitor MLN2238 (ixazomib) in hepatocellular carcinoma cells

2017

AbstractHepatocellular carcinoma (HCC) is one of the common malignancies and is an increasingly important cause of cancer death worldwide. Surgery, chemotherapy, and radiation therapy extend the 5-year survival limit in HCC patients by only 6%. Therefore, there is a need to develop new therapeutic approaches for the treatment of this disease. The orally bioavailable proteasome inhibitor MLN2238 (ixazomib) has been demonstrated to have anticancer activity. In the present study, we investigated the preclinical therapeutic efficacy of MLN2238 in HCC cells through in vitro and in vivo models, and examined its molecular mechanisms of action. MLN2238 inhibited cell viability in human HCC cells He…
