Intravenous lipid emulsion for a life-threatening prothipendyl intoxication.

Prothipendyl, a lipophilic neuroleptic drug, requires a careful dosage regimen due to its potential side effects, including life-threatening arrhythmias.This report outlines a case of severe prothipendyl intoxication, its management and the successful utilisation of Intralipid, an intravenous lipid emulsion, in treating ventricular arrhythmia postmassive prothipendyl ingestion. Additionally, the mechanism of action of Intralipid and the rebound concentration of the lipophilic drug in such scenarios are discussed.

High-frequency synthetic apomixis in hybrid rice.

Introducing asexual reproduction through seeds - apomixis - into crop species could revolutionize agriculture by allowing F1 hybrids with enhanced yield and stability to be clonally propagated. Engineering synthetic apomixis has proven feasible in inbred rice through the inactivation of three genes (MiMe), which results in the conversion of meiosis into mitosis in a line ectopically expressing the BABYBOOM1 (BBM1) parthenogenetic trigger in egg cells. However, only 10-30% of the seeds are clonal.

[Rare sideroblastic anemias: about 2 cases, review of the literature and reminder of the main etiologies].

Sideroblastic anemias in adults are often quickly labeled as myelodysplasias. We report two unfrequent observations of secondary acquired forms. The first one is a 15-year-old girl presented with severe cytopenias.

Comparison of outcome after right colectomy with an enhanced recovery programme in patients with inflammatory bowel disease and patients operated on for other conditions: a monocentric retrospective study.

Purpose: Enhanced recovery programmes (ERPs) after surgery reduce postoperative complications and hospital stay. Patients with inflammatory bowel disease (IBD) often present risk factors for postoperative complications. This accounts for reluctance to include them in ERPs.

Assessment of the roles of SPO11-2 and SPO11-4 in meiosis in rice using CRISPR/Cas9 mutagenesis.

In Arabidopsis, chromosomal double-strand breaks at meiosis are presumably catalyzed by two distinct SPO11 transesterases, AtSPO11-1 and AtSPO11-2, together with M-TOPVIB. To clarify the roles of the SPO11 paralogs in rice, we used CRISPR/Cas9 mutagenesis to produce null biallelic mutants in OsSPO11-1, OsSPO11-2, and OsSPO11-4. Similar to Osspo11-1, biallelic mutations in the first exon of OsSPO11-2 led to complete panicle sterility.

Engineering meiotic recombination pathways in rice.

In the last 15 years, outstanding progress has been made in understanding the function of meiotic genes in the model dicot and monocot plants Arabidopsis and rice (Oryza sativa L.), respectively. This knowledge allowed to modulate meiotic recombination in Arabidopsis and, more recently, in rice.

Fabrication of large-area polymer microfilter membranes and their application for particle and cell enrichment.

A vacuum assisted UV micro-molding (VAUM) process is proposed for the fabrication of freestanding and defect-free polymer membranes based on a UV-curable methacrylate polymer (MD 700). VAUM is a highly flexible and powerful method for fabricating low cost, robust, large-area membranes over 9 × 9 cm with pore sizes from 8 to 20 μm in diameter, 20 to 100 μm in thickness, high aspect ratio (the thickness of the polymer over the diameter of the hole is up to 15 : 1), high porosity, and a wide variety of geometrical characteristics. The fabricated freestanding membranes are flexible while mechanically robust enough for post manipulation and handling, which allows them to be cut and integrated as a plastic cartridge onto thermoplastic 3D microfluidic devices with single or double filtration stages.

Combination of Mechanical and Molecular Filtration for Enhanced Enrichment of Circulating Tumor Cells.

Circulating tumor cells (CTCs) have been linked to cancer progression but are difficult to isolate, as they are very rare and heterogeneous, covering a range of sizes and expressing different molecular receptors. Filtration has emerged as a simple and powerful method to enrich CTCs but only captures cells above a certain size regardless of molecular characteristics. Here, we introduce antibody-functionalized microfilters to isolate CTCs based on both size and surface receptor expression.

Evaluation of the anti-oxidant properties of a SOD-mimic Mn-complex in activated macrophages.

SOD-mimics are small complexes that reproduce the activity of superoxide dismutases, natural proteins that catalytically dismutate the superoxide anion. Activated macrophages, which produce ROS and RNS fluxes, constitute a relevant model to challenge antioxidant activity in a cellular context and were used to test a Mn-complex which was shown to efficiently alter the flow of O(2)(-), ONOO(-) and H(2)O(2).

Indium Tin Oxide devices for amperometric detection of vesicular release by single cells.

The microfabrication and successful testing of a series of three ITO (Indium Tin Oxide) microsystems for amperometric detection of cells exocytosis are reported. These microdevices have been optimized in order to simultaneously (i) enhance signal-to-noise ratios, as required electrochemical monitoring, by defining appropriate electrodes geometry and size, and (ii) provide surface conditions which allow cells to be cultured over during one or two days, through apposite deposition of a collagen film. The intrinsic electrochemical quality of the microdevices as well as the effect of different collagen treatments were assessed by investigating the voltammetric responses of two classical redox systems, Ru(NH(3))(6)(3+/2+) and Fe(CN)(6)(3-/4-).

Environmental risk mapping of canine leishmaniasis in France.

Background: Canine leishmaniasis (CanL) is a zoonotic disease caused by Leishmania infantum, a Trypanosomatid protozoan transmitted by phlebotomine sandflies. Leishmaniasis is endemic in southern France, but the influences of environmental and climatic factors on its maintenance and emergence remain poorly understood. From a retrospective database, including all the studies reporting prevalence or incidence of CanL in France between 1965 and 2007, we performed a spatial analysis in order to i) map the reported cases in France, and ii) produce an environment-based map of the areas at risk for CanL.

Body weight change in women receiving adjuvant chemotherapy for breast cancer: a French prospective study.

Background & Aims: Adjuvant chemotherapy has frequently been associated with weight gain after breast cancer diagnosis. We aimed to prospectively evaluate body weight variations in French patients with early breast cancer.

Methods: This prospective observational study included 272 breast cancer patients who were candidates for adjuvant chemotherapy.

Comprehensive staging allows for excellent outcome in patients with localized malignant germ cell tumor of the ovary.

Background: The management of malignant germ cell tumors of the ovary (OMGCT) requires multidisciplinary expertise. We analyze the surgical and medical outcomes of a cohort of patients treated for OMGCT.

Patients And Methods: Data concerning diagnosis, surgery, and medical decisions were reviewed for all patients seen for postoperative management of OMGCT at the Centre Léon Bérard in Lyon and the Institut Curie in Paris between 1985 and 2003.

Shared decision-making in the physician-patient encounter in France: a general overview.

In France, patients' claim for information and participation to medical decision-making was initiated in the eighties by AIDS associations, then reinforced by the tainted blood scandal and more recently by demands from cancer patients. The right to patient information was recognised on March 4th 2002 by the law pertaining to patients' rights and the quality of the healthcare system. The present article will explore this background by examining the bases, the current status and the development of shared decision-making in the physician-patient encounter in France.

[Breast cancer screening in France].

From a general review of the literature on breast cancer screening, authors appointed by the parliament office for healthcare policy assessment (Office Parlementaire d'Evaluation des Politiques de Santé, OPEPS) demonstrate that, despite recent controversies, screening is both medically and economically effective. The organisation and specifications of screening are considered. The French situation is examined in the light of European recommendations and compared to other systems in place.
