PsJN delays development on grapevine inflorescences.

Grapevine flowering is an important stage in the epidemiology of , the causal agent of gray mold disease. To prevent infection and to minimize postharvest losses, the control of this necrotrophic fungus is mainly based on chemical fungicides application. However, there is a growing interest in other control alternatives.

Formation of Iron Sulfides on Carbon Steel in a Specific Cement Grout Designed for Radioactive Waste Repository and Associated Corrosion Mechanisms.

Carbon steel coupons were buried in a specific low-pH cement grout designed for radioactive waste disposal and left 6 months in anoxic conditions at 80 °C. The corrosion product layers were analyzed by µ-Raman spectroscopy, XRD, and SEM. They proved to be mainly composed of iron sulfides, with magnetite as a minor phase, mixed with components of the grout.

Synthetic Mono-Rhamnolipids Display Direct Antifungal Effects and Trigger an Innate Immune Response in Tomato against .

Natural rhamnolipids are potential biocontrol agents for plant protection against bacterial and fungal diseases. In this work, we synthetized new synthetic mono-rhamnolipids (smRLs) consisting in a rhamnose connected to a simple acyl chain and differing by the nature of the link and the length of the lipid tail. We then investigated the effects of these ether, ester, carbamate or succinate smRL derivatives on development, symptoms spreading on tomato leaves and immune responses in tomato plants.

[Chapter 7.Climate changes and insurance].

Chapter 7. Climate changes and insuranceClimate change challenges insurance, confronting it with uncertainty: risks evolves over time in frequency and intensity, leaving us incapable of measuring the extent of these changes. The following contribution first addresses the way insurance takes into account climate change, from an actuarial and a political point of view.

Pseudomonas knackmussii MLR6, a rhizospheric strain isolated from halophyte, enhances salt tolerance in Arabidopsis thaliana.

Aims: The study aimed for evaluate the efficacy of Pseudomonas knackmussii MLR6 on growth promotion, photosynthetic responses, pigment contents and gene expression of the plant model Arabidopsis thaliana under NaCl stress.

Methods And Results: The strain MLR6 was isolated from the rhizopshere of the halophyte Salsola tetrandra collected from a natural saline Algerian soil. Results showed the ability of MLR6 to induce plant growth promoting traits even under NaCl stress.

Draft Genome Sequence of Plant Growth-Promoting Burkholderia sp. Strain BE12, Isolated from the Rhizosphere of Maize.

sp. strain BE12, isolated from a French agricultural soil, possesses antifungal activity against a set of phytopathogenic fungi and has friendly interactions with grapevine. Here, we present the draft genome sequence of BE12, along with genes related to plant growth-promoting traits and siderophores that this strain contains, supporting its plant growth and antifungal activities.

Screening of wheat endophytes as biological control agents against Fusarium head blight using two different in vitro tests.

In order to find biological control agents (BCAs) for the management of Fusarium head blight (FHB), a major disease on wheat crops worldwide, 86 microorganisms isolated from inner tissues of wheat plants were discriminated for their ability to inhibit the growth of Fusarium graminearum and Fusarium culmorum by in vitro dual culture assays. A group of 22 strains appeared very effective to inhibit F. graminearum (inhibition of 30-51%) and they were also globally effective in controlling F.

The aryl hydrocarbon receptor is functionally upregulated early in the course of human T-cell activation.

The aryl hydrocarbon receptor (AhR) is a ligand-dependent transcription factor that mediates immunosuppression caused by a variety of environmental contaminants, such as polycyclic aromatic hydrocarbons or dioxins. Recent evidence suggests that AhR plays an important role in T-cell-mediated immune responses by affecting the polarization and differentiation of activated T cells. However, the regulation of AhR expression in activated T cells remains poorly characterized.

Inorganic arsenic represses interleukin-17A expression in human activated Th17 lymphocytes.

Trivalent inorganic arsenic [As(III)] is an efficient anticancer agent used to treat patients suffering from acute promyelocytic leukemia. Recently, experimental studies have clearly demonstrated that this metalloid can also cure lymphoproliferative and/or pro-inflammatory syndromes in different murine models of chronic immune-mediated diseases. T helper (Th) 1 and Th17 lymphocytes play a central role in development of these diseases, in mice and humans, especially by secreting the potent pro-inflammatory cytokine interferon-γ and IL-17A, respectively.

Serratia marcescens prosthesis infection successfully treated with meropenem after imipenem failure.

A 78-year-old woman developed an early knee-prosthesis infection due to multiresistant Serratia marcescens that was successfully treated with high-dose meropenem, after failure of a long-term therapy combining imipenem and multiple surgical interventions. Because of its lower neurotoxicity, meropenem might be preferred to imipenem/cilastatin for the treatment of osteo-articular infections due to multiresistant Gram-negative bacilli in the elderly.

Peripheral gangrene in adult-onset Kawasaki disease.

Kawasaki disease (KD) is an acute vasculitis characterized by marked tropism of the coronary vessels. Usually a childhood disease, KD can occasionally be observed in adults. We report a case of adult-onset KD that presented as a prolonged fever of unknown origin with subsequent development of severe vasculitis, manifested by coronary aneurysms and peripheral gangrene of the lower limbs.

Differential diffusions of indinavir and lopinavir in genital secretions of human immunodeficiency virus-infected women.

Plasma and cervicovaginal secretion (CVS) samples were collected from 19 human immunodeficiency virus type 1-infected women on lopinavir- or indinavir-containing regimens. Lopinavir and indinavir were detectable in 29 and 93% of CVS samples, respectively, a finding that may be ascribed to these drugs' differences in protein binding and pK(a). The relationship between lopinavir and indinavir pharmacodynamics and viral evolution in the female genital tract should be assessed over time.

[Intracranial tuberculoma in Africa, with no available neuroimaging. Case report and review of the literature].

The numerous extrapulmonary manifestations of tuberculosis have been well described. Intracranial localizations, including brain stem tuberculoma, are very rare. The authors report a case of brain tuberculoma in a patient with a history of primary pulmonary tuberculosis successfully treated more than twenty years earlier.

Size-selective chemical synthesis of tartrate stabilized cobalt ferrite ionic magnetic fluid.

Ionic magnetic fluid (ferrofluid) is a stable suspension of magnetic nanoparticles in water. Cobalt ferrite nanoparticles are interesting in view of high-density recording storage. The size of the magnetic particles strongly influences the physical properties of the ferrofluids.

Method: A retrospective study of cases diagnosed with peritoneal tuberculosis between 1990 and 1998 in five suburban hospitals in the north-east region of Paris.

Carpal tunnel syndrome caused by Mycobacterium szulgai.

We describe 2 cases of infection due to Mycobacterium szulgai revealed by a carpal tunnel syndrome (CTS) that was the only clinical manifestation. Both patients regularly cleaned their fish tank with bare hands. The diagnosis was made by isolation of M.

Prevalence of cryoglobulins and hepatitis C virus infection in HIV-infected patients.

Purpose And Methods: In order to evaluate the prevalence of positive hepatitis C virus (HCV) serology and cryoglobulinemia in human immunodeficiency virus (HIV)-infected patients, the prevalence and the clinical significance of cryoglobulinemia were prospectively studied in a cohort of 86 HIV-infected subjects seen as outpatients. They were compared to a control group consisting of 101 HIV-HCV+ patients being followed at the same hospital.

Results: HCV serology was positive in 53/86 (61.

[Cardiomyopathies during acquired immunodeficiency syndrome].

Myocardial involvement in the acquired immunodeficiency syndrome is well established on clinical data, echocardiographic studies, macropathological findings and histological studies on autopsy or endomyocardial biopsy specimens. The condition may present with asymptomatic left ventricular dysfunction with a low ejection fraction, acute or subacute myocarditis or cardiac failure and dilated cardiomyopathy. A few cases of hypertrophic cardiomyopathy with HIV infection have also been reported.
