HIV-1-specific CD8 cytotoxic and CD4 helper T-lymphocytes, which are respectively the central effector and regulatory cells in viral infections, together with fully functional antigen-presenting cells, are essential at all stages of HIV-1 infection to control viral activity. Recent studies indicate that such protective HIV-1-specific immune responses can be preserved/induced in HIV-1-infected i...
BACKGROUND Couples in whom the man is infected by human immunodeficiency virus (HIV) increasingly request assisted reproductive technology (ART) to allow safe procreation. Semen quality is critical in such situations. METHODS Semen characteristics were evaluated in 189 HIV-infected men requesting ART. At the time of semen analysis all men were healthy and 177 were receiving anti-retroviral th...
1. In general, HIV-1 infected individuals should not receive any live viral or bacterial vaccines (eg. Measles/Mumps/Rubella, monovalent Rubella, BCG, yellow fever, oral Typhoid Ty21a, varicella-zoster, oral Polio, vaccinia). There have been instances of lethal infections with live vaccinia vaccines following vaccination of HIV-infected persons.(3) This principle however applies particularly to...
BACKGROUND Gastrointestinal symptoms, in particular diarrhoea, are common in non-treated HIV-1 infected individuals. Although various enteric pathogens have been implicated, the aetiology of diarrhoea remains unexplained in a large proportion of HIV-1 infected patients. Our aim is to identify the cause of diarrhoea for patients that remain negative in routine diagnostics. METHODS In this stud...
Introduction: Toxoplasma gondii is a coccidian parasite and has, as intermediate hosts, many warm-blooded animals, including mammals and birds. Congenital toxoplasmosis is one of the most important infectious diseases seen in fetuses and infants born from mothers infected with Tox.gondii during pregnancy. Congenital infection, which may occur if a mother is infected for the first time during pr...
Wolbachia is a cytoplasmically inherited alpha-proteobacterium found in a wide range of host arthropod and nematode taxa. Wolbachia infection in Drosophila is closely associated with the expression of a unique form of post-fertilization lethality termed cytoplasmic incompatibility (CI). This form of incompatibility is only expressed by infected males suggesting that Wolbachia exerts its effect ...
We report a case of mycotic abdominal aortic aneurysm where the use of hybrid imaging with gallium scan demonstrated increased uptake in the infected aneurysm and aided in differentiating physiological uptake in the bowel from pathological uptake.
the infection of food animals to hydatid cyst is a concern from economic and public health stand points. in this survey, the prevalence of hydatid cysts was studied in 547 buffaloes slaughtered at the slaughterhouse in urmia. samples from 58 cases (10. 6%) were infected to hydatid cysts. the infection rates of lung and liver were 45 cases (77. 5%) and 37 cases (63. 7%), respectively, while each...
Objective(s): The novel healing choices for handling of infections due to multidrug resistant Staphylococcus aureus are reguired. HAMLET has been reported to be able to sensitize bacterial pathogens to traditional antimicrobial agents. The aim was to assess wound healing activity of methicillin in presence of HAMLET in methicillin resistant S. aureus (MRSA) infected wounds. Materials and Method...
