Effects Of Acculturation On Hiv/Aids Sexual Risk Behaviors Among Asian And Pacific Islander (Api) Women, Margaret Cabotage Salud

Loma Linda University Electronic Theses, Dissertations & Projects

Background. In the US women are the fastest growing group for sexually transmitted infections (STIs), including HIV and AIDS. In addition, the estimated AIDS cases among female adults and adolescents, aged 13-19, increased from 7% in 1985 to approximately 26% in 2002. Most infections occur by heterosexual transmission with 53% occurring through contact with a high-risk sexual partner. While overall HIV/AIDS rates in the Asian Pacific Islander (API) community remain low, they are rising and HIV testing rates, one of the major prevention strategies for HIV, are lower than that of other populations. Furthermore, very little is known about APIs …

Plasmacytoid Dendritic Cells Sense Skin Injury And Promote Wound Healing Through Type I Interferons, Josh D. Gregorio

Dissertations and Theses (Open Access)

Plasmacytoid dendritic cells (pDCs) are a rare population of circulating cells, which selectively express intracellular Toll-like receptors (TLR)-7 and TLR-9 and have the capacity to produce large amounts of type I IFNs (IFN-a/b) in response to viruses or host derived nucleic acid containing complexes. pDCs are normally absent in skin but accumulate in the skin of psoriasis patients where their chronic activation to produce IFN-a/b drives the disease formation. Whether pDCs and their activation to produce IFN-a/b play a functional role in healthy skin is unknown. Here we show that pDCs are rapidly and transiently recruited into healthy human and …

A Review Of Psychosocial Support And The Challenges Faced In Disclosing Hiv Positive Status To Children In Kibera, Katherine Lesyna

Independent Study Project (ISP) Collection

The AIDS pandemic has become an increasingly global problem as well as an everyday reality for most people living in sub-Saharan Africa. In 2009, an estimation of the number of adults and children living with HIV/AIDS in sub-Saharan Africa totaled around 22.4 million.1 The people that have been affected most by the pandemic are women and children.
In Kenya, about 1.5 million people are infected with HIV, about 180,000 of them being children.2 While a lot has been done to reduce HIV infections and treat those who are infected, children have been left behind until recently. There is still much …

Immune Recognition Of Self Nucleic Acids Driven By Endogenous Antimicrobial Peptides: Role In Autoimmunity, Dipyaman Ganguly

Dissertations and Theses (Open Access)

Innate immune recognition of extracellular host-derived self-DNA and self-RNA is prevented by endosomal seclusion of the Toll-like receptors (TLRs) in the dendritic cells (DCs). However, in psoriasis plasmacytoid dendritic cells have been found to be able to sense self-DNA molecules in complex with the endogenous cationic antimicrobial peptide LL37, which are internalized into the endosomal compartments and thus can access TLR9. We investigated whether this endogenous peptide can also interact with extracellular self-RNA and lead to DC activation. We found that LL37 binds self-RNA as well as self-DNA going into an electrostatic interaction; forms micro-aggregates of nano-scale particles protected from …

Small Molecule Inhibition Of Macrophage Tnf-A Release, Razwana Wahdat

Seton Hall University Dissertations and Theses (ETDs)

Tumor Necrosis Factor Alpha (TNF-a) is a vital pro-inflammatory cytokine produced in response to the activation ofthe innate immune response via the Toll-like receptor signal transduction pathway. This thesis explores the release and inhibition of TNF-a from RAW 264.7 mouse macrophages and human U937 cells that have been exposed to a potent activator of innate immunity. Using lipopolysaccharide (LPS), a Gram negative bacterial endotoxin, in the presence or absence of proinflammatory cytokine interferon 'Y (IFN-y) as activators ofthe TLR-4 pathway, a robust release ofTNF­ a was observed. Co-incubation of stimulated macrophages with the tyrosine phosphatase inhibitor, sodium vanadate, resulted in …

Hiv: Make The Diagnosis And Take The Next Step, Julie G. Stewart, Amy R. Weinberg

Nursing Faculty Publications

With the CDC urging screening for all willing patients, providers will be testing and managing a growing number of HIV-positive individuals.

The CDC estimates that with more than 40,000 new infections annually, more than 1.2 million people in the United States are living with HIV-and 24% to 27% may not be aware of their infection status.1 Studies have shown that HIV is often diagnosed late in the disease process, when the individual has already developed AIDS, which typically occurs 8 to 11 years after HIV infection.2 Research also points to missed opportunities to offer HIV testing and diagnose the infection …

Immune Function And Health Outcomes In Women With Depression, Cherie Howk, Mary P. Bennett

Nursing Faculty Publications

This research reports immune function and health outcomes in women with depression, as compared with a nondepressed control group. Using Psychoneuroimmunolgy theory and a descriptive comparison design, scores on the Beck Depression Inventory (BDI) were used to divide 40 non-hospitalized Caucasian women between the ages of 18 and 65 years into either the control or depression comparison group. Women with depression were found to report significantly more incidences of illness over the previous two months and they were found to have significantly more indicators of illness at the time of the exam as compared to the controls. However, contrary to …

Cerebral Toxoplasmosis In A Patient With Acquired Immunodeficiency Syndrome, Rohana Naqi, Muhammad Azeemuddin, Humera Ahsan

Department of Radiology

Cerebral toxoplasmosis commonly affects patients with advanced HIV immunodeficiency. Toxoplasmosis in patients who are immunocompromised can be severe and debilitating in patients with Central Nervous System (CNS) involvement and the condition may be fatal. We report the case of a 40-year-old man who was a known case of HIV and presented with cerebral toxoplasmosis. His Magnetic Resonance Imaging (MRI) scan showed multiple ring enhancing lesions with extensive surrounding oedema in supratentorial as well as infratentorial region. Lesions were mainly located in the periventricular region as well as at the grey-white matter junction and showed enhancement in the periphery as well …

Bone Marrow Stromal Cells Use Tgf-Β To Suppress Allergic Responses In A Mouse Model Of Ragweed-Induced Asthma, K. Nemeth, A. Keane-Myers, J. M. Brown, D. D. Metcalfe, J. D. Gorham

Dartmouth Scholarship

Bone marrow stromal cells [BMSCs; also known as mesenchymal stem cells (MSCs)] effectively suppress inflammatory responses in acute graft-versus-host disease in humans and in a number of disease models in mice. Many of the studies concluded that BMSC- driven immunomodulation is mediated by the suppression of pro- inflammatory Th1 responses while rebalancing the Th1/Th2 ratio toward Th2. In this study, using a ragweed induced mouse asthma model, we studied if BMSCs could be beneficial in an allergic, Th2- dominant environment. When BMSCs were injected i.v. at the time of the antigen challenge, they protected the animals from the majority of …

An Epitope From Acanthamoeba Castellanii That Cross-React With Proteolipid Protein 139-151-Reactive T Cells Induces Autoimmune Encephalomyelitis In Sjl Mice, Chandirasegaran Massilamany, David Steffan, Jay Reddy

Jay Reddy Publications

We report here that an epitope (aa, 83-95) derived from Acanthamoeba castellanii (ACA) induces clinical signs of experimental autoimmune encephalomyelitis (EAE) in SJL/J mice reminiscent of the disease induced with myelin proteolipid protein (PLP) 139-151. By using IA^s/tetramers, we demonstrate that both ACA 83-95 and PLP 139-151 generate antigen-specific cross-reactive CD4 T cells and the T cells secrete identical patterns of cytokines and induce EAE with a similar severity. These results may provide insights into the pathogenesis of multiple sclerosis and ACA-induced granulomatous encephalitis.

Prevention With Positives: How Do We Reach Them In The Community?, Avina Sarna, Jerry Okal, Stanley Luchters, Nzioki King'ola, Scott Geibel

HIV and AIDS

In the past, HIV prevention efforts have focused primarily on developing risk-reduction interventions for those presumed to be HIV-negative and therefore at risk of becoming infected with HIV. In recognition of the need for prevention among people living with HIV (PLHIV), programs have been initiated in Africa, but primarily in clinical settings for those who are on antiretroviral therapy (ART). There is little knowledge about how to reach those PLHIV not on ART, and therefore not in regular contact with the health system or with effective prevention messages. This diagnostic study aimed to address the gap in information on how …

Factors Affecting Enrolment Of Plhiv Into Art Services In India, Avina Sarna, Damodar Bachani, Mary Philip Sebastian, Ruchi Sogarwal, Madhusudana Battala

HIV and AIDS

At the end of 2007, India had an estimated 2.31 million people living with HIV, and an HIV prevalence of 0.34 percent. Despite the low HIV prevalence, these statistics place India among countries with a large number of people living with HIV (PLHIV). To address the care and support needs of PLHIV, the Ministry of Health and Family Welfare, Government of India, initiated a national program in 2004 to provide free antiretroviral therapy (ART) for PLHIV. By March 2009, there were 211 functioning Antiretroviral Treatment Centers and 254 Community Care Centers across the country, and to date 217,781 individuals are …

Plasma Pharmacokinetics And Tissue Disposition Of Novel Dextran- Methylprednisolone Conjugates With Peptide Linkers In Rats, Suman Penugonda, Hitesh K. Agarwal, Keykavous Parang, Reza Mehvar

Pharmacy Faculty Articles and Research

The plasma and tissue disposition of two novel dextran prodrugs of methylprednisolone (MP) containing one (DMP-1) or five (DMP-5) amino acids as linkers were studied in rats. Single 5-mg/kg doses (MP equivalent) of each prodrug or MP were administered intravenously, and blood and tissue samples were collected. Prodrug and drug concentrations were quantitated using HPLC, and noncompartmental pharmacokinetic parameters were estimated. Whereas conjugation of MP with dextran in both prodrugs substantially decreased the clearance of the drug by ∼200-fold, the accumulations of the drug in the liver, spleen, and kidneys were significantly increased by conjugation. However, the extent of accumulation …

Synthesis, Antiviral And Contraceptive Activities Of Nucleoside-Sodium Cellulose Sulfate Acetate And Succinate Conjugates, Hitesh K. Agarwal, Anil Kumar, Gustavo F. Doncel, Keykavous Parang

Pharmacy Faculty Articles and Research

Chemical conjugates between sodium cellulose sulfate (CS), displaying contraceptive and HIV-entry inhibiting properties, and nucleoside reverse transcriptase inhibitors (NRTIs) (3′-azido-2′,3′-dideoxythymidine (AZT), 3′-fluoro-2′,3′-dideoxythymidine (FLT), or 2',3'-dideoxy-3'-thiacytidine (3TC)) were designed to simultaneously provide contraceptive and anti-HIV activity. Two linkers, acetate and succinate, were used to conjugate the nucleoside analogs with CS. The conjugates containing cellulose sulfate-acetate (CSA) (e.g., AZT-CSA and FLT-CSA) were found to be more potent than CS and other conjugates (e.g., AZT-succinate-CS, and FLT-succinate-CS). The presence of both sulfate and the acetate groups on cellulose were critical for generating maximum anti-HIV activity. In addition to showing equal potency against wild-type …
