Experiences of students with HIV/AIDS in rural, post-conflict Uganda

2015

The roll out of Anti-Retroviral Therapy across Sub-Saharan Africa has given rise to a new generation of adolescents that previously would not have survived into their teen years. The aim of this research is to give voice to these young people, specifically HIV positive students, in the rural, post-conflict area of Katakwi, Uganda. Through the lens of empowerment, which focuses on participation, capacity building, leadership potential, and relationships, this research examines the factors in these students’ lives that contribute to their empowerment, or the absence of these factors that then have the potential to disempower them. It considers the way the students themselves see both the prot…

HIV/AIDS education in regular and special (deaf) secondary schools in Ghana

2011

This study investigated HIV/AIDS education in two secondary schools in Ghana comparing students’ knowledge, attitude and behaviour. Furthermore, this study investigated students most trusted source of HIV/AIDS knowledge, how students see the disease against other diseases and how HIV education is grounded in the schools curricular. In all, 283 students were involved in the survey. Their ages were between 12 and 25. The findings established that student’s knowledge on how to avoid the disease, mode of transmission, and prevention were very high. However, it was unearthed that female students fear for the disease was higher than their male counterparts and this have motivated them to know the…

Kulttuuri ja aids-kriisi : vastikkeellinen seksi tansanialaisessa slummissa

2018

Artikkelissa tarkastellaan etnologian keinoin miksi Tansanian nuoriso harjoittaa korkean hivtartuntariskin omaavia seksuaalisia käytänteitä. Tutkimus perustuu Tansanian suurimmassa kaupungissa Dar es Salaamissa tehtyihin 128 teemahaastatteluun. Analyysin lähtökohtana on ajatus siitä, että kulttuuristen odotusten ja asenteiden huolellinen analyysi antaa tutkijoille mahdollisuuden löytää uusia ratkaisuja hiv-tartuntariskin vähentämiseksi köyhillä kaupunkialueilla Saharan eteläpuolisessa Afrikassa. peerReviewed

Evolutionary plasticity of SH3 domain binding by Nef proteins of the HIV-1/SIVcpz lentiviral lineage

2021

The accessory protein Nef of human and simian immunodeficiency viruses (HIV and SIV) is an important pathogenicity factor known to interact with cellular protein kinases and other signaling proteins. A canonical SH3 domain binding motif in Nef is required for most of these interactions. For example, HIV-1 Nef activates the tyrosine kinase Hck by tightly binding to its SH3 domain. An archetypal contact between a negatively charged SH3 residue and a highly conserved arginine in Nef (Arg77) plays a key role here. Combining structural analyses with functional assays, we here show that Nef proteins have also developed a distinct structural strategy—termed the "R-clamp”—that favors the formation …

Epidemiat : taloushistoriallinen katsaus

2020

Epidemioilla on lyhyen ja pitkän aikavälin taloudellisia ja demografisia vaikutuksia sekä yhteiskunnallisia seurauksia. Samankaltaisuuksistaan huolimatta epidemioiden lopputulokset ovat riippuvia tapahtumaympäristöistään – patogeenit saattavat vaatia hyvin erityiset olosuhteet levitäkseen ja tuottaakseen epidemioita. Historiallinen vertailu osoittaa, että yhteiskuntia muuttaneet suuret tartuntatautiepisodit (kuten musta surma) esiintyvät verrokkeina useammin kuin niiden yleistyvyys tai tyypillisyys puoltaisivat. Epidemiat saattavat haitata alue- ja makrotaloutta hyvinkin pitkällä aikavälillä, mutta tämä on riippuvaista sokkien kohdentumisesta ja laajemmasta taloudellisesta ympäristöstä. Kuo…
