Objectives The aim of the study was to evaluate age, sex, breed, clinical signs, time between onset of signs and presentation, diagnostic procedures, method of extraction, location and nature of foreign bodies (FBs) in confirmed cases of tracheobronchial FBs in cats. We hypothesised that bronchoscopy was effective in extracting tracheobronchial FBs in cats. Methods A retrospective study was performed using clinical reports from three private practices in France between May 2009 and November 2014.

A solid-phase microextraction (SMPE) method coupled to a gas chromatography-mass spectrometry analysis was optimized to analyze the pentafluorobenzyl bromide (PFBBr) derivatives of the volatile thiols 4-methyl-4-mercapto-2-pentanone (4MMP), 3-mercaptohexyl acetate (3MHA) and 3-mercaptohexanol (3MH) in wine. This method used deuterated analogue compounds as internal standards. It allowed us to significantly reduce the matrix effect, resulted in good repeatability for all the compounds (RDS<9.

The gamma-aminobutyrate (GABA) shunt, an alternative route for the conversion of alpha-ketoglutarate to succinate, involves the glutamate decarboxylase Gad1p, the GABA transaminase Uga1p and the succinate semialdehyde dehydrogenase Uga2p. This pathway has been extensively described in plants and animals, but its function in yeast remains unclear. We show that the flux through Gad1p is insignificant during fermentation in rich sugar-containing medium, excluding a role for this pathway in redox homeostasis under anaerobic conditions or sugar stress.

Ethanethiol and diethyl disulfide (DEDS) most often occurred at levels above their olfactive threshold in wines with nauseous sulfur-linked smells. As ethanethiol is very oxidizable and chemically reactive, a stable isotopic dilution analysis of both ethanethiol and its disulfide in wines using solid phase microextraction and GC-MS was developed. The latter involved the determination of the proportion of DEDS formed by oxidation of the thiol during the analysis conditions, which was obtained by the use of two differently labeled disulfide standards.

A 41-year-old recipient of matched unrelated BMT acquired a severe mucocutaneous herpes simplex virus (HSV) type I infection during acyclovir prophylaxis. He was subsequently treated with high-dose acyclovir, but the HSV infection continued. In vitro analysis of the HSV isolate, obtained before and after the administration of high-dose acyclovir, demonstrated marked resistance to acyclovir but sensitivity to the antiviral agent foscarnet.

The relationship between Epstein-Barr virus (EBV) and the host is profoundly disturbed by allogeneic bone marrow transplantation (BMT) because EBV resides in the recipient's hematopoietic system, which has to be destroyed in the majority of cases, and in the donor's hematopoietic system, i.e., the marrow graft.

In contrast to its role in B-lymphomagenesis, Epstein-Barr Virus (EBV) only incidentally has been associated with T-cell lymphomas. In the present report we describe a fourth patient with EBV-related T-cell lymphoma. The patient presented with an angio-immunoblastic lymphadenopathy (AILD)-like T-cell lymphoma.

We have shown in two allogeneic bone marrow transplant recipients that Epstein-Barr virus can be eradicated by the BMT procedure or its complications, and that these patients are susceptible to infection with a new EBV strain. This conclusion was based on a combination of EBV serology and virus strain identification ("Ebnotyping," using the size variations of 5 EBV nuclear antigens). In the present study, we conducted a serological survey of EBV infection in 153 marrow graft recipients and their donors.

According to recent studies, vitamin D deficiency may contribute to the osteoporosis observed in elderly subjects, with reduced intestinal calcium absorption and secondary hyperparathyroidism. Vitamin D deficiency is often present in elderly people, due to inadequate diet and confinement at home. The administration of either oral vitamin D in doses of 4,000 IU per day, or six-monthly intramuscular injections of ergocalciferol 600,000 IU, combined with a daily intake of at least 1 g of calcium brings back to normal both 25 OH D concentrations and parathyroid hormone levels.

Wild-type strains of Epstein-Barr virus (EBV) can be distinguished on the basis of variations in the molecular weight of virus-encoded, growth transformation-associated proteins. This approach was used to study the persistence of EBV in two seropositive recipients of allogeneic bone marrow transplants. The first patient received marrow from her EBV-seronegative brother, became EBV seronegative after grafting, and remained so for greater than 1200 days.

Calcium and phosphorus metabolism was studied in 101 institutionalized subjects over 70 years of age (mean: 82.5 years). The study was performed in serum and urine; it included parathyroid hormone and calcidiol (250HD3) assays and radiological examination of bones with determination of Meunier's index and metacarpal cortical index.

In this report, we describe the development of a rapidly progressive Epstein-Barr virus (EBV) related cerebral lymphoma in an 11 year old girl, eight months after renal transplantation. No serological evidence for a persistent EBV infection was found, but Epstein-Barr nuclear antigen (EBNA) could be demonstrated in the tumor. The clinical course of our patient was different from EBV-related syndromes in renal transplanted patients described in previous reports.

Annual chest radiographs, work history and mortality of 1,973 workers in an asbestos-cement factory were correlated with age and with duration and level of dust exposure. Degree of radiographic lung change was significantly related to fibre-years of exposure in the case of small lung opacities, pleural adhesions and pleural thickening. For 29 cases of asbestosis diagnosed between 1963 and 1977, a highly significant dose-response relationship was found.
