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...

BACKGROUND Men who have sex with men (MSM) are a hidden but emerging population susceptible to HIV infection against a background of rapidly increasing HIV prevalence in China. Low HIV testing levels and multiple partnerships among MSM are two major contributing factors to HIV transmission. METHODS We conducted a cross-sectional survey among 447 Chinese MSM in Changsha and Tianjin cities from...

BACKGROUND Targeted human papillomavirus (HPV) vaccine could prevent HPV-related cancers and genital warts among men who have sex with men (MSM). In order to develop effective vaccination programmes for MSM, it is crucial to understand their knowledge, beliefs about HPV and attitudes towards HPV vaccine. METHODS A systematic search of 10 databases examined articles investigating HPV knowledge...

Methylsulfonylmethane (MSM) is a sulfur-containing compound commonly found in diet and known to reduce oxidative stress. This trial was conducted to determine whether single dose supplementation with MSM attenuates post-exercise oxidative stress in healthy untrained young men. Sixteen untrained men volunteered for this study. Participants were randomized in a double-blind placebo-controlled fas...
