ITPA deficiency and ribavirin level are still predictive of anaemia in HCV–HIV-coinfected patients receiving ribavirin combined with a first-generati…
2017
Background We aimed to determine the impact of inosine triphosphatase (ITPA) deficiency on ribavirin (RBV)-induced anaemia in HIV–HCV-coinfected patients receiving a triple therapy including the haematotoxic direct-acting antiviral agent boceprevir (BOC). Methods Patients of the ANRS HC27 BocepreVIH study were genotyped for two ITPA single nucleotide polymorphisms involved in ITPA deficiency. RBV trough concentration (Ctrough) was determined at week (W)4 and W8. Impact of ITPA deficiency on anaemia, RBV Ctrough, response and haematotoxicity (grade 3/4 anaemia, erythropoietin [EPO] use, RBV dose reduction or transfusion between day [D]0 and W8) was evaluated. Impact of RBV Ctrough on anaemia…
N-Acetylneuraminic acid storage disease
1985
Increased amounts of free sialic acid were found in body fluids, leukocytes, cultured fibroblasts, and liver tissue of a four-year-old boy with mental retardation, ataxia, and clinical and radiologic findings of a mild mucopolysaccharidosis. A diagnosis of Salla disease was made though in contrast to earlier reports, recurrent upper respiratory infections and hepatosplenomegaly were present already in infancy, and skeletal abnormalities of dysostosis multiplex were found in early childhood. Free sialic acid in the urine was identified as N-acetylneuraminic acid by 1H-NMR spectroscopy. Sialidase activities were normal. Increased amounts of bound sialic acid were found in liver and cultured f…
Nephrosis in two siblings with infantile sialic acid storage disease
1990
The diagnosis of infantile sialic acid storage disease (ISSD) was established in two siblings on the basis of typical clinical signs and the biochemical findings of hyperexcretion and intracellular storage of free sialic acid. A severe, steroid resistant nephrosis occurred in both siblings. The activities of lysosomal enzymes, including sialidase, were normal. A combined detection method for sialic acids with Limax flavus agglutinin labelling and phosphotungstic acid staining showed severely alterated sialic acid components in epithelial kidney cells and indicate a causal relationship between the nephrosis and the underlying biochemical defect. Further observations of ISSD patients with ren…
Hypoadiponectinemia, cardiometabolic comorbidities and left ventricular hypertrophy
2014
This study was designed to evaluate the prevalence of cardiometabolic comorbidities and the changes in left ventricular geometry and function in 135 subjects subgrouped according to low or normal total adiponectin plasma (ADPN) levels. Left ventricular (LV) internal diameter/height, total LV mass (LVM) and LVM index (LVMI), relative wall thickness (RWT), LV ejection fraction by echocardiography and diastolic parameters by pulsed-wave Doppler were calculated. Body mass index (BMI) (p < 0.0001), waist-to-hip ratio (p < 0.03), triglycerides (p < 0,001), prevalence of obesity (p < 0.005), visceral obesity (p < 0.003), left ventricular hypertrophy (LVH) (p < 0.001), metabolic syndrome (p < 0.000…
Duchenne muscular dystrophy and idiopathic hyperCKemia segregating in a family
1995
A 7-month-old boy with gross motor delay and failure to thrive presented with rhabdomyolysis following an acute asthmatic episode. During hospitalization an electrocardiographic conversion to a Wolff-Parkinson-White type 1 (WPW) pattern took place. Duchenne muscular dystrophy (DMD) was suspected based on elevated creatine kinase (CK) serum levels, muscle biopsy, and family history. The diagnosis was confirmed by molecular analysis, which documented a deletion corresponding to cDNA probe 1-2a in the dystrophin gene, in the propositus and in an affected male cousin of his mother. "Idiopathic" hyperCKemia was found in the propositus, his father, and 5 of his relatives. We suggest that the unus…
Effects of inbound marketing communications on HEIs’ brand equity: the mediating role of the student’s decision-making process. An exploratory resear…
2016
ABSTRACTA context of increased competition between higher education institutions (HEIs) for attracting potential national and international students has led universities to implement marketing communication strategies. Those strategies which are used to some extent include, among others, interactive inbound marketing. The purpose of the present exploratory study is to identify how HEIs can develop to improve their image and awareness by using new interactive marketing communication tools mediated by the student’s decision-making process. To conduct our investigation, we used both a qualitative (seven semi-structured interviews) and a quantitative survey (n = 121) methodology. Based on data …
Influence of axial force and corrosion on failure of prestressed concrete structures considering M-V interaction
2021
Abstract Existing prestressed concrete structures suffer from degradation of prestressing for two main reasons: a defect of the sheath infills (cement grout) of bonded tendons, and corrosion of steel strands. These two causes, often concomitant, lead to a reduction over time of the effectiveness of initial prestressing, in addition to the ordinary tension losses due to concrete shrinkage and creep, and to steel relaxation. In many cases a consequence of bad grouting in bonded tendons is that the structure shows an intermediate behavior between that of external prestressing and that of internal bonded prestressing. This, added to damage to wires due to corrosion, makes it essential for the d…
Surface Periodic Poling in Lithium Niobate and Lithium Tantalate
2005
Periodic Poling of Lithium Niobate crystals (PPLN) by means of electric field has revealed the best technique for finely tailoring PPLN structures and parameters, which play a central role in many current researches in the field of nonlinear integrated optics. Besides the most studied technique of bulk poling, recently a novel technique where domain inversion occurs just in a surface layer using photoresist or silica masks has been devised and studied. This surface periodic poling (SPP) approach is best suited when light is confined in a thin surface guiding layer or stripe, as in the case of optical waveguide devices. Also, we found that SPP respect to bulk poling offers two orders of magn…
Comparison of Delivery Methods in Phage Therapy against Flavobacterium columnare Infections in Rainbow Trout
2021
Viruses of bacteria, bacteriophages, specifically infect their bacterial hosts with minimal effects on the surrounding microbiota. They have the potential to be used in the prevention and treatment of bacterial infections, including in the field of food production. In aquaculture settings, disease-causing bacteria are often transmitted through the water body, providing several applications for phage-based targeting of pathogens, in the rearing environment, and in the fish. We tested delivery of phages by different methods (via baths, in phage-coated material, and via oral delivery in feed) to prevent and treat Flavobacterium columnare infections in rainbow trout fry using three phages (FCOV…
The use of phage FCL-2 as an alternative to chemotherapy against columnaris disease in aquaculture
2015
Flavobacterium columnare, the causative agent of columnaris disease in fish, causes millions of dollars of losses in the US channel catfish industry alone, not to mention aquaculture industry worldwide. Novel methods are needed for the control and treatment of bacterial diseases in aquaculture to replace traditionally used chemotherapies. A potential solution could be the use of phages, i.e., bacterial viruses, host-specific and self-enriching particles that can be can easily distributed via water flow. We examined the efficacy of phages to combat columnaris disease. A previously isolated phage, FCL-2, infecting F. columnare, was characterized by sequencing. The 47 142 bp genome of the phag…
