BACKGROUND Immunocompromised persons infected with Mycobacterium tuberculosis (MTB) have increased risk of tuberculosis (TB) reactivation, but their management is hampered by the occurrence of false-negative results of the tuberculin skin test (TST). The T-cell interferon (IFN)-gamma release blood assays T-SPOT.TB (TS.TB) [Oxford Immunotec; Abingdon, UK](More)
The objective of the study was to assess the incidence, risk factors, and survival of gram-positive bloodstream infections (GP-BSI(s)) among liver transplant recipients during the first year after transplantation. Between October 2000 and September 2006, 42 episodes of GP-BSI(s) occurred in 205 patients with an overall incidence of 0.20 episodes/patient.(More)
BACKGROUND The activity of virus-specific T lymphocytes, among which those capable of a polyfunctional response against the viral protein gag, is crucial to control HIV infection. OBJECTIVE The objective of this study is to investigate the polyfunctionality of gag-specific T cells in different phases of HIV infection, analyzing markers related to T-helper(More)
The objective of this study was to evaluate the influence of different concentrations of epidermal growth factor (EGF) on in vitro maturation of domestic cat oocytes. A total of 444 cat oocytes were matured in MSOF (maturation synthetic oviductal fluid) in the presence of varying EGF concentrations: (1) MSOF (control); (2) MSOF+10 ng/mL EGF (EGF10); (3)(More)
OBJECTIVE To investigate immunological changes during CD4-guided therapy interruption in HIV(+) patients who suspended HAART. PATIENTS Seventeen patients aged > 18 years, who had received HAART for at least 12 months, and had a pre-interruption CD4+ cell count > 500 cells/microl, interrupted treatment. Median nadir CD4(+) cell count was 288 cells/microl.(More)
This research examines for the 1st time the effects of relative deprivation and relative gratification, based on social comparison, on implicit and overt forms of discrimination toward the outgroup in a minimal group setting. Study 1 showed that compared to a control condition, relative deprivation and relative gratification enhanced implicit(More)
The effects of two commonly used drugs for anaesthesia in the domestic cat, ketamine and medetomidine, on features of electroejaculated semen and on sperm flow in this species were evaluated performing three experiments. This is the first study about these topics in the domestic cat. In Experiment 1, ketamine or medetomidine effects on cat sperm quality(More)
Long-term side effects may represent a relevant burden of antiretroviral treatment (ART) in HIV-infected patients with good CD4 immune reconstitution over extended time spans. CD4-guided treatment interruption (TI) has been evaluated to address this point and may result in a wide spectrum of time off ART in different patient cohorts. We studied whether(More)
Quality and in vitro fertilizing ability of frozen-thawed cat semen collected by urethral catheterization (CT) or electroejaculation (EE) after medetomidine administration were compared. Sperm collection was performed by an urinary tomcat catheter and, 4 days apart, by electroejaculation from each of eight tomcats. Results showed that semen collected by CT(More)
