BACKGROUND Although there are limited numbers of incidence and persistence estimates for anal human papillomavirus (HPV) in women and in men who have sex with men (MSM), there are no such reports for men who have sex with women (MSW). METHODS Genotyping was performed on anal samples from men, aged 18-70, from São Paulo, Brazil; Cuernavaca, Mexico; and Tampa, Florida, who provided specimens at...

Men who have sex with men (MSM) may be more likely to smoke than general population men. Such population comparisons typically do not control for demographic differences and have not tested reasons for MSMs' greater tobacco use. We compared MSM with general population men in data that allowed us to control demographic differences, and hypothesized that MSM would report more tobacco use, due to ...

Little is known about the impact of combination HIV prevention interventions for men who have sex with men (MSM) and the impacts on the wider epidemics. Modelling analyses of MSM-specific interventions across varied HIV epidemics may inform evidence-based responses. The Goals model was adapted to project the impacts of providing HIV interventions for MSM and access to expanded coverage of antir...

The authors say male-to-male sexual contact, even if not recent, is an “important marker” for being at high risk for HIV. With MSM-Ever, overall HIV prevalence was 9.1%, compared to only 0.2% among men with no history of sexual contact with other males. HIV was detected among 16.5% of MSM-Ever who identified as gay, a rate roughly four times higher than found with bisexual MSM-Ever. No HIV infe...

Breast cancer is the most aggressive form of all cancers, with high incidence and mortality rates. The purpose of the present study was to investigate the molecular mechanism by which methylsulfonylmethane (MSM) inhibits breast cancer growth in mice xenografts. MSM is an organic sulfur-containing natural compound without any toxicity. In this study, we demonstrated that MSM substantially decrea...

BACKGROUND To describe the level and risk factors for suicidal behaviors in Chinese men who have sex with men (MSM). METHODS A total of 807 MSM were recruited using a respondent-driven sampling method from Anshan, Benxi, Dandong, and Shenyang cities in northeastern China. RESULTS Chinese MSM had lifetime prevalences of suicide ideation (18.3%), plan (8.7%) and attempt (4.6%) that were about...

Abstract Cell death is a fundamental aspect of tissue homeostasis that can expose potentially immunogenic cell components must be removed to prevent inflammatory autoimmunity. We have shown immune suppression in response apoptotic phagocytosis (a process called efferocytosis) dependent on tissue-resident macrophages (Mf). Indeed, if we disrupt Mf regulatory responses post-efferocytosis, the sam...

Magnetic shape memory (MSM) alloys are a new class of smart materials with extraordinary strains up to 12% and frequencies in the range of 1 to 2 kHz. The MSM actuator is a potential device which can achieve high performance electromagnetic actuation by using the properties of MSM alloys. However, significant non-linear hysteresis behavior is a significant barrier to control the MSM actuator. I...

The aim of this study was to evaluate the potential transmission of HCV strains between HIV-positive men who have sex with men (MSM) and HIV-negative MSM. Since 2000, an ongoing epidemic of HCV infections is observed among HIV-positive MSM in high-income countries. However, HCV infections in HIV-negative MSM are investigated to a lesser extent due to the lack of follow-up in this population and...

BACKGROUND Two rounds of integrated biological and behavioural assessment (IBBA) surveys were done among men who have sex with men (MSM) in Andhra Pradesh during 2006 and 2009. Avahan, the India AIDS initiative, funded by the Bill and Melinda Gates Foundation implemented HIV prevention interventions among MSM starting around the time of the first round of IBBA. METHODS Data on socio-demograph...
