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...

BACKGROUND The transmission through contacts among MSM (men who have sex with men) is one of the dominating contributors to HIV prevalence in industrialized countries. In Amsterdam, the capital of the Netherlands, the MSM risk group has been traced for decades. This has motivated studies which provide detailed information about MSM's risk behavior statistically, psychologically and sociological...

BACKGROUND Men who have sex with men (MSM) are much more likely to be infected with HIV than the general population. China has a sizable population of MSM, including gay, bisexual men, money boys and some rural workers. So reducing HIV infection in this population is an important component of the national HIV/AIDS prevention and control program. METHODS We develop a mathematical model using a...

This article examines whether incorporating investors’ uncertainty, as captured by the conditional volatility of sentiment, can help forecasting stock markets. In this regard, using Markov-switching multifractal (MSM) model, we find that uncertainty substantially increase accuracy forecasts market according to forecast encompassing test. We further provide evidence MSM outperforms dynamic corre...

BACKGROUND Measuring prevalence and incidence of sexually transmitted infections in hard to reach populations like men who have sex with men (MSM) is hampered by unknown size and regional distribution of this population. Community sample- and study-based measurements are often fraught with participation biases and do not allow generalization of the results for other regions or the whole populat...

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...

BACKGROUND Men who have sex with men (MSM) are disproportionately affected by HIV. The proven efficacy of circumcision in reducing the risk of HIV acquisition among African heterosexual males has raised the question of whether this protective effect may extend to MSM populations. We examined the potential impact of circumcision on an HIV epidemic within a population of MSM. METHODS A mathemat...

BACKGROUND The Marginal Structural Cox Model (Cox-MSM), an alternative approach to handle time-dependent confounder, was introduced for survival analysis and applied to estimate the joint causal effect of two time-dependent nonrandomized treatments on survival among HIV-positive subjects. Nevertheless, Cox-MSM performance in the case of multiple treatments has not been fully explored under diff...

Background Men who have sex with men (MSM) have a high lifetime risk of anogenital warts and cancers related to infection with human papillomavirus (HPV). They also benefit less from herd protection than heterosexual males in settings with female-only HPV vaccination. Methods We evaluated the potential health impact and cost-effectiveness of offering vaccination to MSM who visit genitourinary...
