Small-x, Diffraction and Vector Mesons
2015
This talk discusses recent progress in some topics relevant for deep inelastic scattering at small x. We discuss first differences and similarities between conventional collinear factorization and the dipole picture of deep inelastic scattering. Many of the recent theoretical advances at small x are related to taking calculations in the nonlinear saturation regime to next-to-leading order accuracy in the QCD coupling. On the experimental side significant recent progress has been made in exclusive and diffractive processes, in particular in ultraperipheral nucleus-nucleus collisions.
Unfolding a transmembrane helix dimer: A FRET study in mixed micelles
2009
The exact nature of membrane protein folding and assembly is not understood in detail yet. Addition of SDS to a membrane protein dissolved in mild, non-polar detergent results in formation of mixed micelles and in subsequent denaturation of higher ordered membrane protein structures. The exact nature of this denaturation event is, however, enigmatic, and separation of an individual helix pair in mixed micelles has also not been reported yet. Here we followed unfolding of the human glycophorin A transmembrane helix dimer in mixed micelles by fluorescence spectroscopy. Energy transfer between differently labelled glycophorin A transmembrane helices decreased with increasing SDS mole fractions…
Peripheral Neuropathy and VIth Nerve Palsy Related to Randall Disease Successfully Treated by High-Dose Melphalan, Autologous Blood Stem Cell Transpl…
2010
Randall disease is an unusual cause of extraocular motor nerve (VI) palsy. A 35-year-old woman was hospitalized for sicca syndrome. The physical examination showed general weakness, weight loss, diplopia related to a left VIth nerve palsy, hypertrophy of the submandibular salivary glands, and peripheral neuropathy. The biological screening revealed renal insufficiency, serum monoclonal kappa light chain immunoglobulin, urinary monoclonal kappa light chain immunoglobulin, albuminuria, and Bence-Jones proteinuria. Bone marrow biopsy revealed medullar plasma cell infiltration. Immunofixation associated with electron microscopy analysis of the salivary glands showed deposits of kappa light chai…
Intracerebral Borna Disease Virus Infection of Bank Voles Leading to Peripheral Spread and Reverse Transcription of Viral RNA
2011
Bornaviruses, which chronically infect many species, can cause severe neurological diseases in some animal species; their association with human neuropsychiatric disorders is, however, debatable. The epidemiology of Borna disease virus (BDV), as for other members of the family Bornaviridae, is largely unknown, although evidence exists for a reservoir in small mammals, for example bank voles (Myodes glareolus). In addition to the current exogenous infections and despite the fact that bornaviruses have an RNA genome, bornavirus sequences integrated into the genomes of several vertebrates millions of years ago. Our hypothesis is that the bank vole, a common wild rodent species in traditional B…
Editor's Choice – Follow-up of Patients After Revascularisation for Peripheral Arterial Diseases: A Consensus Document From the European Society of C…
2019
International audience; Peripheral arterial diseases comprise different clinical presentations, from cerebrovascular disease down to lower extremity artery disease, from subclinical to disabling symptoms and events. According to clinical presentation, the patient's general condition, anatomical location and extension of lesions, revascularisation may be needed in addition to best medical treatment. The 2017 European Society of Cardiology guidelines in collaboration with the European Society for Vascular Surgery have addressed the indications for revascularisation. While most cases are amenable to either endovascular or surgical revascularisation, maintaining long-term patency is often chall…
Basics of anatomy

Peripheral nerves contain motor, sensory, and vegetative fibers that are strictly separate, but in close proximity to each other (Figure 1).
Flupirtine protects both neuronal cells and lymphocytes against induced apoptosis in vitro: Implications for treatment of AIDS patients
1999
In the present study we demonstrate that flupirtine, an already clinically used, centrally acting, non-opiate analgesic agent, protects rat cortical neurons against HIV-gp120 induced apoptotic cell death. The drug was active at concentrations between 1 and 10 microg/ml. Furthermore we show inhibition of in vitro induced apoptosis in human blood mononuclear cells, using flupirtine. Induced apoptosis in peripheral blood mononuclear cells from healthy individuals and HIV-1 infected patients was reduced to approximately 50% after in vitro preincubation with flupirtine at concentrations between 0.1 and 10 microg/ml. The anti-apoptotic effect of flupirtine was restricted to CD3+ lymphocytes and i…
Asthma Control: The Right Inhaler for the Right Patient
2015
Inhaled therapy is the cornerstone of asthma management in that it optimizes the delivery of the medication to the site of action. The effectiveness of inhaled therapy is affected by the correct choice of the device and proper inhalation technique. In fact, this influences the drug delivery and distribution along the bronchial tree, including the most peripheral airways. In this context, accumulating evidence supports the contribution of small airways in asthma, and these have become an important target of treatment. In reality, the “ideal inhaler” does not exist, and not all inhalers are the same. Advances in technology has highlighted these differences, and have led to the design of new d…
Chemotherapy-Induced Neuropathy and Diabetes: A Scoping Review
2021
Although cancer and diabetes are common diseases, the relationship between diabetes, neuropathy and the risk of developing peripheral sensory neuropathy while or after receiving chemotherapy is uncertain. In this review, we highlight the effects of chemotherapy on the onset or progression of neuropathy in diabetic patients. We searched the literature in Medline and Scopus, covering all entries until 31 January 2021. The inclusion and exclusion criteria were: (1) original article (2) full text published in English or Spanish; (3) neuropathy was specifically assessed (4) the authors separately analyzed the outcomes in diabetic patients. A total of 259 papers were retrieved. Finally, eight art…
The 2-5A System and HIV Infection
1994
The human immunodeficiency virus type 1 (HIV-1) is the etiologic agent of acquired immunodeficiency syndrome (AIDS). The progression of this retro viral disease is associated with various clinical manifestations, including the acquisition of an immunodeficient state, the frequent presence of neurological disorders, and some malignancies (reviewed in Barre-Sinoussi et al. 1983; Wong-Staal and Gallo 1985; Fauci 1988). Immunologic dysfunctions caused by HIV-1 infection include disorders in the production of cytokines (Murray et al. 1984; Abb et al. 1986). For example, a significant decrease in the production of interferon-α (IFN-α) by cultured peripheral blood mononuclear cells (PBMC) from pat…
