ABSTRACT: There remains considerable discontent between globalization scholars about how to conceptualize its meaning and in regards to epistemological and methodological questions concerning how we can come to understand how these processes ultimately operate, intersect and transform our lives. This article argues that to better understand what globalization is and ...

Histoplasma capsulatum is a common opportunistic pathogen that often causes disseminated infection among AIDS patients from endemic areas. Virtually any organ system can be affected, but biliary involvement has not been described. We report the first case of AIDS cholangiopathy associated with H. capsulatum.

Opiate abuse increases the risk for human immunodeficiency virus (HIV) infection, while both opiates and HIV may impact the immune and nervous systems. To model potential interactions between opiate drugs and HIV on the brain, neurometabolite levels were evaluated in simian immunodeficiency virus (SIV)-infected macaques with or without chronic morphine ...

We assessed the prevalence of AIDS among children diagnosed with active tuberculosis (TB) in Espírito Santo State, Brazil, by linking TB and AIDS surveillance databases using Reclink software and SPSS. Among 411 pediatric TB cases from 2000 to 2006, 27 (7%) were co-infected with AIDS. Most children were unable to ...

Cytomegalovirus (CMV) retinitis is a common opportunistic infection among patients with AIDS and still causes visual morbidity despite the wide spread usage of highly active antiretroviral therapy (HAART). The ubiquitous CMV pathogen contains a human interleukin-10 (IL-10) homolog in its genome and utilizes it to evade host immune reactions through ...

OBJECTIVE: To investigate association of TIM1 sequence variations with HIV/AIDS progression. INTRODUCTION:: HIV-1 infected individuals have wide variations in disease progression including AIDS. T cell immunoglobulin and mucin 1 (TIM1) is a cell surface protein involved in the regulation of Th1/Th2 immune response. MATERIALS AND METHODS: We sequenced the highly ...

The DNA/RNA editing enzyme activation-induced cytidine deaminase (AID) is mutagenic and has been implicated in human tumorigenesis. Helicobacter pylori infection of gastric epithelial cells leads to aberrant expression of AID and somatic gene mutations. We investigated whether AID induces genetic aberrations at specific chromosomal loci that encode tumor-related proteins in ...

HIV-1 infection has rapidly spread worldwide and has become the leading cause of mortality in infectious diseases. The duration for development of AIDS (AIDS progression) is highly variable among HIV-1 infected individuals, ranging from 2-3 years to no signs of AIDS development in the entire lifetime. Several factors regulate the ...

Since the first case of acquired immunodeficiency syndrome (AIDS) was reported in 1981, AIDS, as the global disease affecting 33.2 million people in 2007, has always been an unsolved problem worldwide. Reverse transcriptase (RT) is a crucial enzyme in the life cycle of human immunodeficiency virus type 1 (HIV-1), and ...

The human APOBEC3 family of cytidine deaminases provides intrinsic immunity to retroviral infection. A naturally occurring 29.5-kb deletion removes the entire APOBEC3B gene. We examined the impact of the APOBEC3B gene deletion in >4000 individuals from 5 human immunodeficiency virus type 1 (HIV-1) natural history cohorts. The hemizygous genotype had ...

Expert chess players, specialized in different openings, recalled positions and solved problems within and outside their area of specialization. While their general expertise was at a similar level, players performed better with stimuli from their area of specialization. The effect of specialization on both recall and problem solving was strong ...

Mitochondrial function plays a role in both AIDS progression and HAART toxicity; therefore, we sought to determine whether mitochondrial DNA variation revealed novel AIDS restriction genes, particularly as mitochondrial DNA single-nucleotide polymorphisms are known to influence regulation of oxidative phosphorylation, reactive oxygen species production, and apoptosis. This is a retrospective ...

BACKGROUND: The literature on the involvement of mannose-binding lectin (MBL) in human immunodeficiency virus (HIV) transmission and acquired immunodeficiency syndrome (AIDS) is conflicting. Polymorphisms in the MBL2 gene reduce the level of protein and alter its structure. Thus, we investigated whether MBL2 alleles and plasma concentrations of MBL are associated ...

Acid-fast tuberculous mycobacterial infections are common in AIDS and are regarded as secondary "opportunistic infections." According to the National Institute of Allergy and Infectious Diseases, TB is the major attributable cause of death in AIDS patients. Could such bacteria play a primary or causative role in AIDS? Certainly, In screening ...

Since the earliest days of the AIDS epidemic, clinicians and researchers have recognized the importance of lymphoid tissue both in the clinical manifestations of disease and in its pathogenesis. Generalized lymphadenopathy was one of the earliest harbingers of AIDS in the United States and over the past 27 years an ...

As free-living sea-lice larvae are difficult to sample directly, lice abundances on fish have recently been used to study larvae in the water. In the KLV problem, juvenile wild salmon migrate past a salmon farm, and the change of infection with distance along the migration route is used to estimate ...

This article is derived from the original "Cytokines and HIV infection: Is AIDS a Tumor Necrosis Factor Disease?" published in AIDS, 1991 Dec;5(12):1405-17

The HIV-1 epidemic among injecting drug users (IDU) in Taiwan is caused primarily by CRF07_BC infections. Evolutionary analyses, which utilize outgroup reference strains from northwestern China (Xinjiang), reveal that CRF07_BC was introduced into southern Taiwan in 1998-2001 and spread to central-northern Taiwan in 2001-2003, causing the largest HIV/AIDS epidemic in ...

AIDS-associated, CCR5-tropic (R5) HIV-1 clones, isolated from a patient that never developed CXCR4-tropic HIV-1, replicate to a greater extent and cause greater cytopathic effects than R5 HIV-1 clones isolated before the onset of AIDS. Previously, we showed that HIV-1 Env substantially contributed to the enhanced replication of an AIDS clone. ...

Polymorphisms in FcgammaR genes are associated with susceptibility to or severity of a number of autoimmune and infectious diseases. We found that HIV-infected men in the Multicenter AIDS Cohort Study with the FcgammaRIIa RR genotype progressed to a CD4(+) cell count of <200/mm(3) at a faster rate than individuals with ...

Non-Hodgkin's B cell lymphoma (NHL) is a common cancer in HIV infection. Many NHL are thought to result from errors in class switch recombination and/or somatic hypermutation, processes that occur in germinal center B cells, and require the activity of activation induced cytidine deaminase (AID). Since NHL is a common ...

Disseminated histoplasmosis was uncommon prior to the AIDS epidemic, and cutaneous eruption rarely was seen. Since the onset of the worldwide AIDS epidemic, histoplasmosis has become a more common opportunistic fungal infection and should be considered in the differential diagnosis of mucocutaneous lesions in patients with AIDS in endemic areas. ...

A series of trivalent CD4-mimetic miniproteins was synthesized, in which three CD4M9 miniprotein moieties were tethered on a threefold-symmetric scaffold. The trivalent miniproteins were designed to target the CD4-binding sites displayed in the trimeric gp120 complex of HIV-1. The synthesis takes advantage of the highly efficient ligation between a cysteine-tagged ...

Although HIV is the necessary and sufficient causative agent of AIDS, genetic and environmental factors markedly influence the pace of disease progression. Clinical and experimental evidence suggests that human herpesvirus 6A (HHV-6A), a cytopathic T-lymphotropic DNA virus, fosters the progression to AIDS in synergy with HIV-1. In this study, we ...

Activation-induced cytidine deaminase (AID) is expressed in germinal centers of lymphoid organs during immunoglobulin diversification, in bone marrow B cells after infection with Abelson murine leukemia retrovirus (Ab-MLV), and in human B cells after infection by hepatitis C virus. To understand how viruses signal AID induction in the host we ...

The pathogenesis of AIDS has proven to be quite complex and dynamic, with most of the critical events (e.g., transmission, CD4(+) T cell destruction) occurring in tissues that are not easily accessible for analysis. In addition, although the disease can progress over years, many critical events happen within the first ...

The devastating consequences of AIDS pandemic will probably only be controlled when a vaccine is developed that is safe, effective, affordable, and simple enough to permit implementation in developing countries where the impact of AIDS is most severe. However, the major obstacle for the control of the spread of AIDS ...

This paper will give a resume of many of the important factors, which form the immense problems in sexually transmitted infections in the world in 2007. STI is the term used to include sexually transmitted diseases and HIV/AIDS. It aims to enlighten both the specialist dermato-venereologist as well as all ...

BACKGROUND: Ethnobotanical surveys were carried out to document herbal remedies used in the management of HIV/AIDS opportunistic infections in Bukoba Rural district, Tanzania. The district is currently an epicenter of HIV/AIDS and although over 90% of the population in the district relies on traditional medicines to manage the disease, this ...

Little is known about the effect of immune reconstitution inflammatory syndrome (IRIS) on the long-term clinical outcome. Of 52 opportunistic infections (OI) occurring within one year after the start of HAART in 387 HIV patients, 33 (63%) were classified as having IRIS. The patients with IRIS showed no significant difference ...

Madarosis may be a presenting feature of a number of vision and life-threatening conditions, including herpes zoster, leprosy, HIV/AIDS, trachoma, malignant eyelid tumors, discoid lupus, scleroderma, and hypothyroidism. It may occur via two broad pathogenic pathways: scarring and non-scarring, which indicates the potential for lash re-growth. Madarosis may occur as ...

The behavior of the Schistosoma mansoni infection in patients with AIDS has not been explored. The case of a young woman with schistosomiasis mansoni, AIDS, and cytomegalovirus disease is reported. The authors suggest that the helminth was not a bystander in this case, or rather, by interfering with the host's ...

Cardiovascular disease is an important complication of human immunodeficiency virus/acquired immune deficiency syndrome (AIDS), but the mechanism(s) involved are poorly understood. Although co-infecting pathogens have been implicated as an important factor in AIDS progression, no studies have investigated these interactions in cardiac tissue. We recently demonstrated that the murine AIDS ...

HIV/AIDS programmes and interventions are more likely to succeed if they engage with local people's beliefs about AIDS causation. This study examined beliefs about general illness, sexually-transmitted infection (STI) and AIDS aetiology in rural Mwanza, Tanzania. From 1999-2002, participant observation was carried out in nine villages for a total of ...

Understanding how lentiviruses can infect terminally differentiated, non-dividing cells has proven a very complex and controversial problem. It is, however, a problem worth investigating, for it is central to HIV-1 transmission and AIDS pathogenesis. Here I shall attempt to summarise what is our current understanding for HIV-1 infection of non-dividing ...

The heart and great vessels are not the sites most frequently affected by opportunistic infections and neoplastic processes in patients with acquired immune deficiency syndrome (AIDS). However, cardiovascular complications occur in a significant number of such patients and are the immediate cause of death in some. The spectrum of cardiovascular ...

HIV is the most significant risk factor for many opportunistic infections like tuberculosis, bacterial infections etc. In this paper, we designed aminopyrimidinimino isatin lead compound as a novel non-nucleoside reverse transcriptase inhibitor with broad-spectrum chemotherapeutic properties for the effective treatment of AIDS and AIDS-related opportunistic infections. Compound 1-ethyl-6-fluoro-1,4-dihydro-4-oxo-7[[N(4)-[3'-(4'-amino-5'-chloroben-zylpyrimidin-2'-yl)imino-1'-(5-methylisatinyl)] methyl]N(1)-piperazinyl]-3-quinoline carboxylic ...

An interesting interaction pattern has been found between HIV-1 and GBV-C/HGV, resulting in protection against progression to AIDS. The mechanisms involved in this interaction remain to be clarified. We examined the current knowledge concerning this coinfection and developed hypotheses to explain its effects. A better understanding of this interaction could ...

We report a case of lues maligna (ulceronodular cutaneous syphilis) mimicking mycosis fungoides in an individual with AIDS and review the literature of this variant of syphilis in human immunodeficiency virus (HIV)-infected individuals. A comparison of the histological similarities and differences between lues maligna, late cutaneous syphilis and mycosis fungoides ...

Of the 40 million people living with HIV/AIDS worldwide in 2003, only 7% received highly active antiretroviral treatment (HAART). Without treatment, approximately half of AIDS patients will suffer from NeuroAIDS including neurological dysfunction, peripheral neuropathies, motor impairment, cognitive difficulties and frank dementia. HAART has reduced mortality from AIDS in the ...

The neurological complications of HIV contribute importantly to patient morbidity and mortality. Major common AIDS-related CNS diseases are ADC, metabolic encephalopaties, CMV encephalitis, TE, PCNSL, PML, criptococcal meningitis, and aseptic meningitis. After HAART, declines in incidence and improved outcome of several HIV-1 related opportunistic infections, including CNS-ADIs have been reported. ...

Movement disorders are a potential neurologic complication of acquired immune deficiency syndrome (AIDS), and may sometimes represent the initial manifestation of HIV infection. Dopaminergic dysfunction and the predilection of HIV infection to affect subcortical structures are thought to underlie the development of movement disorders such as parkinsonism in AIDS patients. ...

AIDS advocates now say they look back at the late 1990s as a time when they never had it so good: new antiretroviral regimens turned HIV infection into a chronic rather than fatal disease, and funding increased each year. But the recent retrenchment has given rebirth to protests, rallies, and ...

Paracoccidioidomycosis is one of the most frequent systemic and endemic mycoses of Latin America caused by a dimorphic fungus. In AIDS patients, paracoccidioidomycosis appears as a severe and disseminated disease with a wide spectrum of clinical findings. The CD4 counts are usually less than 200 cell/mu L. We present a ...

Several rifamycin derivatives have been developed during the last 15 years for the treatment of mycobacterial infections. For tuberculosis, rifabutin (RFB) showed strong activity and seemed to be suitable when tuberculosis patients were also treated for their AIDS infection. Rifapentine (RPT) was evaluated in patients with or without AIDS for ...

HIV-1 encodes for one of the human glutathione peroxidases. As a consequence, as it is replicated, its genetic needs cause it to deprive HIV-1 seropositive individuals not only of glutathione peroxidase, but also of the four basic components of this selenoenzyme, namely selenium, cysteine, glutamine, and tryptophan. Eventually this depletion ...

The plight of millions of HIV-infected individuals without access to antiretroviral (ARV) medications constitutes an enormous problem. Religious values can influence policymakers in public and personal health issues. This article posits that Jewish religious law mandates the broadest possible access to ARV medications for HIV-infected individuals, and argues that wealthy ...

One year after the human immunodeficiency virus (HIV) was pinpointed as the etiological agent of the acquired immunodeficiency syndrome (AIDS) in humans, chimpanzees were identified as one of the few living species also capable of sustaining persistent HIV-1 infection. During the mid to late 1980s, as the AIDS epidemic spread ...
