Multifocal Biliary Cystadenocarcinoma of the Liver: CT and Pathological Findings
2006
Biliary cystadenocarcinoma is a rare tumor that originates from the hepatobiliary epithelium. Although this tumor can affect any portion of the biliary tree, intrahepatic location is more common. It is usually a slow growing tumor and often asymptomatic until it reaches a considerable size. The lesion is most often solitary and large when discovered; multiple lesions or metastases within the liver are very rare. A 63-year-old man was referred to our institute for weight loss, abdominal discomfort, worsening bulky symptoms in the right upper abdominal quadrant, and an increase in serum aminotransferases that had been present for several months. Spiral CT of the abdomen demonstrated two lesi…
Postmortem distribution of dihydrocodeine and metabolites in a fatal case of dihydrocodeine intoxication.
1998
A report of a fatal dihydrocodeine ingestion under substitution therapy is given. Quantitation of dihydrocodeine, dihydromorphine, N-nordihydrocodeine, dihydrocodeine-6-, dihydromorphine-6- and dihydromorphine-3-glucuronide was performed simultaneously after solid-phase extraction prior to HPLC analysis, and the analytes were detected using their native fluorescence. Postmortem concentrations of blood samples from different sampling sites as well as from liver, kidney and cerebrum are reported. A hair sample was investigated to prove long-term use of the substitute drug. Site-to-site differences of the analytes from blood samples were very small. The partition behavior of the opioid glucuro…
The relationship between animal cruelty in children and adolescent and interpersonal violence: A systematic review
2019
Abstract The following study is a systematic review of the relationship between animal cruelty and interpersonal violence. The systematic literature review following PRISMA guidelines and combined with the application of inclusion and exclusion criteria, enabled us to locate 32 studies published between 1995 and July 2017. Overall, the results show that episodes of animal cruelty during childhood and adolescence tend to co-occur alongside other forms of violent and antisocial behaviors. Cruelty to animals was associated with bullying, behavioral problems, experiences of abuse (emotional, physical and sexual), and juvenile delinquency. Furthermore, recurrent animal cruelty during childhood a…
IQSEC2-related encephalopathy in males and females: a comparative study including 37 novel patients.
2019
Variants in IQSEC2, escaping X inactivation, cause X-linked intellectual disability with frequent epilepsy in males and females. We aimed to investigate sex-specific differences.

Characterization of rat glutathione transferases in olfactory epithelium and mucus
2019
International audience; The olfactory epithelium is continuously exposed to exogenous chemicals, including odorants. During the past decade, the enzymes surrounding the olfactory receptors have been shown to make an important contribution to the process of olfaction. Mammalian xenobiotic metabolizing enzymes, such as cytochrome P450, esterases and glutathione transferases (GSTs), have been shown to participate in odorant clearance from the olfactory receptor environment, consequently contributing to the maintenance of sensitivity toward odorants. GSTs have previously been shown to be involved in numerous physiological processes, including detoxification, steroid hormone biosynthesis, and am…
Factors of good visual outcome in acute post-cataract endophthalmitis (friends group)
2009
International audience; Purpose: To analyze initial clinical factors of good visual outcome in patients with acute endophthalmitis following cataract surgery. Methods: A prospective study was performed in 4 University hospital (Dijon, Grenoble, Lyon, Saint-Etienne, FRIENDS group) on 100 patients with acute post-cataract endophthalmitis. Factors related to cataract surgery (complications), the initial presentation and the microbiological identification were analyzed according to the final visual outcome using univariate and multivariate analysis (SPSS 12.0). Results: 46% out of the patients had a final visual acuity less than or equal to 0.3 logMar (good visual outcome) at 6 months while 10%…

Monounsaturated fatly acid metabolism and colon cancer cells proliferation : role of Stearoyl-CoA desaturase-1 and effect of conjugated linoleic acid…
2012
Cancer cells adapt their metabolism in response to signals from the microenvironment and proliferation. Thus, MonoUnsaturated Fatty Acid (MUFA) synthesis is increased in colon cancer cells, and associated with increased Stearoyl-CoA Desaturase (SCD) activity, the rate limiting enzyme of MUFA biosynthesis. Polyunsaturated Fatty Acid (PUFA), as isomers of conjugated linoleic acid (CLA), exert inhibitor activity on SCD-1 and have anti-cancer properties, but their mechanisms are not yet clear. In this context, the aim of this work was first to evaluate the role of SCD-1 in the proliferation of colon cancer cells (CCC) and to define the underlying mechanisms. In a second time, we provide new inf…
