The determinants of recognition specificity of self-incompatibility in Brassica are SRK in the stigma and SP11/SCR in the pollen, both of which are encoded in the S locus. The nucleotide sequence analyses of many SRK and SP11/SCR alleles have identified several interspecific pairs of S haplotypes having highly similar sequences between B. oleracea and B. rapa. These interspecific pairs of S haplotypes are considered to be derived from common ancestors and to have maintained the same recognition specificity after speciation. In this study, the genome structures of three interspecific pairs of S haplotypes were compared by sequencing SRK, SP11/SCR, and their flanking regions. Regions between SRK and SP11/SCR in B. oleracea were demonstrated to be much longer than those of B. rapa and several retrotransposon-like sequences were identified in the S locus in B. oleracea. Among the seven retrotransposon-like sequences, six sequences were found to belong to the ty3 gypsy group. The gag sequences of the retrotransposon-like sequences were phylogenetically different from each other. In Southern blot analysis using retrotransposon-like sequences as probes, the B. oleracea genome showed more signals than the B. rapa genome did. These findings suggest a role for the S locus and genome evolution in self-incompatible plant species.

We used qualitative methods to explore factors, which might explain increased anxiety in patients attending a sexually transmitted infection (STI) clinic. Twenty patients, who scored significantly for anxiety on the Hospital Anxiety and Depression Scale (HADS) attended a 20-minute interview. This explored factors contributing to their current psychological symptoms. Transcripts revealed three main themes. First were factors related to possible STIs and the clinic visit. These included health anxieties about HIV or fertility and clinic factors, including staff attitudes and clinic location. Second were factors unrelated to the clinic, including previous emotional difficulties or substance misuse. Third were issues concerning stigma, embarrassment and shame. The origins of anxiety in STI patients are multifactorial and difficult to identify during brief appointments. Despite modern clinics and attitudes, stigma and embarrassment remain prominent. Interventions to address these factors could improve psychological health in this patient group.

This paper presents an analysis of responses to the first criminal convictions for HIV transmission in England and Wales within a sample of people living with HIV. These findings represent an important contribution to the development of well-informed prosecution policy. The responses were collected during 20 focused group discussions with a community and web-recruited sample of heterosexual African men and women, and gay and bisexual men (n = 125) living with diagnosed HIV in London, Manchester and Brighton. The vast majority (90%) of comments made were critical of the implementation and impact of criminalization. In particular, respondents expressed concern about the way in which criminal convictions conflict with messages about shared responsibility for 'safer sex', and the extent to which such cases will exacerbate existing stigma and discrimination related to HIV. Most felt that the successes achieved by human rights approaches to HIV prevention, treatment, and care were placed under threat by the growing culture of blame encouraged by criminal prosecutions.

Based on data from a population-based survey conducted in 2003 in a province in southwestern China, we provide data on knowledge about HIV transmission, HIV stigmatizing attitudes, and willingness to take HIV-related risks. There were widespread misconceptions, especially among females, about how HIV is transmitted and negative feelings toward someone with HIV. There was considerable willingness to take more sexual risks (not using a condom; nondisclosure of HIV seropositive status) with a secondary than with a primary sexual partner. The misconceptions and stigma surrounding HIV may make it difficult to focus on HIV as a 'disease' as opposed to a 'social malady' for survey participants.

A recent investigation found evidence that the transition of Arabidopsis thaliana from ancestral self-incompatibility (SI) to full self-compatibility occurred very recently and suggested that this occurred through a selective fixation of a nonfunctional allele (PsiSCR1) at the SCR gene, which determines pollen specificity in the incompatibility response. The main evidence is the lack of polymorphism at the SCR locus in A. thaliana. However, the nearby SRK gene, which determines stigma specificity in self-incompatible Brassicaceae species, has extremely high sequence diversity, with 3 very divergent SRK haplotypes, 2 of them present in multiple strains. Such high diversity is extremely unusual in this species, and it suggests the possibility that multiple, different SRK haplotypes may have been preserved from A. thaliana's self-incompatible ancestor. To study the evolution of S-haplotypes in the A. thaliana lineage, we searched the 2 most closely related Arabidopsis species Arabidopsis lyrata and Arabidopsis halleri, in which most populations have retained SI, and found SRK sequences corresponding to all 3 A. thaliana haplogroup sequences. Our molecular evolutionary analyses of these 3 S-haplotypes provide an independent estimate of the timing of the breakdown of SI and again exclude an ancient transition to selfing in A. thaliana. Comparing sequences of each of the 3 haplogroups between species, we find that 2 of the 3 SRK sequences (haplogroups A and B) are similar throughout their length, suggesting that little or no recombination with other SRK alleles has occurred since these species diverged. The diversity difference between the SCR and SRK loci in A. thaliana, however, suggests crossing-over, either within SRK or between the SCR and SRK loci. If the loss of SI involved fixation of the PsiSCR1 sequence, the exchange must have occurred during its fixation. Divergence between the species is much lower at the S-locus, compared with reference loci, and we discuss two contributory possibilities. Introgression may have occurred between A. lyrata and A. halleri and between their ancestral lineage and A. thaliana, at least for some period after their split. In addition, the coalescence times of sequences of individual S-haplogroups are expected to be less than those of alleles at non-S-loci.

Genital human papillomavirus (HPV) infection is the most common sexually transmitted virus in the United States, causing genital warts, cervical cell abnormalities, and cervical cancer in women. To inform HPV education efforts, 35 focus groups were conducted with members of the general public, stratified by gender, race/ethnicity, and urban/rural location. Focus groups explored participants' knowledge, attitudes, and beliefs about HPV and a hypothetical HPV vaccine as well as their communication preferences for HPV-related educational messages. Audience awareness and knowledge of HPV were low across all groups. This, along with an apparent STD-associated stigma, served as barriers to participants' hypothetical acceptance of a future vaccine. Although information about HPV's high prevalence and link to cervical cancer motivated participants to learn more about HPV, it also produced audience fear and anxiety. This research suggests that HPV- and HPV-vaccine-related education efforts must be approached with extreme caution. Other practical implications are discussed.

The objectives of this study were to assess the nature and effect of stigma on disclosure of diagnosis to sexual partners among those with problematic disease. Data from questionnaires and semistructured interviews were collected and analysed. Data regarding anxiety were also collected using a validated tool. Ethical approval was received from the Chelsea and Westminster Healthcare National Health Service (NHS) Trust. Disclosure of diagnosis tended to occur in the context of established relationships. Herpes-related stigma was associated with non-disclosure of diagnosis to sexual partners. The point prevalence of moderate to severe anxiety in this sample was 32%. The use of suppressive medication did not affect anxiety scores. In conclusion, the reaction to a diagnosis of genital herpes is influenced by a socially constructed understanding and the decision to disclose or not is influenced by this. Stigma is a barrier to disclosure of genital herpes diagnosis. Management strategies aimed at encouraging disclosure to partners must address perceived stigma.

To respond to the HIV/AIDS epidemic in China, the National Center for AIDS/STD Control and Prevention established the Division of Treatment and Care in late 2001. The pilot for the National Free ART Program began in Henan Province in 2002, and the program fully began in 2003. Treatment efforts initially focused on patients infected through illicit blood and plasma donation in the mid-1990s and subsequently expanded to include HIV-infected injection drug users, commercial sex workers, pregnant women, and children. The National Free ART Database was established in late 2004, and includes data on current patients and those treated before 2004. Over 31 000 adult and pediatric patients have been treated thus far. Challenges for the program include integration of drug treatment services with ART, an under-resourced health care system, co-infections, stigma, discrimination, drug resistance, and procurement of second-line ART. The merging of national treatment and care, epidemiologic, and drug resistance databases will be critical for a better understanding of the epidemic, for earlier identification of patients requiring ART, and for improved patient follow-up. The Free ART Program has made considerable progress in providing the necessary care and treatment for HIV-infected people in China and has strong government support for continued improvement and expansion.

This study aims to measure indicators of HIV-related stigma among students of high schools in the North West of Libya. The results will be part of baseline data and evaluation of the impact of successive interventions. Understanding the behaviour of risk groups in a society, such as young people, is essential in order to draw effective prevention strategies. Behavioural surveillance surveys have been shown to make an important and useful contribution to informing the response to HIV. This study was part of a large Knowledge, Attitude, Beliefs and Practice survey. A self-administrated questionnaire method was used. The response rates were high (83-92%). Despite high level of stigma shown by both boys and girls in the study, 91% of students supported providing free care to HIV infected individuals. The HIV intervention programmes for young people should operate within a comprehensive strategy to combat HIV/AIDS. The stigmatizing and the discriminatory perceptions of HIV infected individuals should be addressed as part of the education campaign.

We examined AIDS stigma among male inmates and male and female staff at a state prison in the southern region of the USA. Inmates and staff rated people with AIDS more negatively than someone with other diseases (diabetes, cancer, heart disease and high blood pressure). Inmates and staff were concerned about being treated differently if they tested seropositive. They also described AIDS stigma as a barrier to seeking HIV testing. Both instrumental (inaccurate beliefs about casual contact causing transmission of the virus) and symbolic factors (negative attitudes about injection drug use) predicted AIDS stigma. Negative attitudes about homosexuality predicted AIDS stigma among Caucasian prison staff and inmates, but not among African American staff and inmates. The results indicate the need to address HIV/AIDS stigma in developing HIV treatment, care and prevention programs in the prison environment.
