BACKGROUND Internet-based sampling methods may reach men who have sex with men (MSM) who don't attend physical venues frequented by MSM and may be at higher risk of HIV infection. METHODS Multivariate logistic regression was used to examine characteristics of adult MSM participants in 2 studies conducted in the same 5 U.S. cities: the 2003-2005 National HIV Behavioral Surveillance System (NHB...

Methylsulfonylmethane (MSM) is a naturally occurring sulfur compound with well-known anti-oxidant properties and anti-inflammatory activities. But, its effects on bone are unknown. Growth hormone (GH) is regulator of bone growth and bone metabolism. GH activates several signaling pathways such as the Janus kinase (Jak)/signal transducers and activators of transcription (STAT) pathway, thereby r...

The Poisson statistics of photon arrival rates are applied to the imaging performance of the Quanta Image Sensor (QIS) concept. Signal and noise as a function of exposure is analyzed and we find SNR only obeys the square-root law under sparse exposure. The Dlog H characteristic of the QIS is quantified. Linearity and dynamic range are also investigated. I. SIGNAL Photons are emitted from light ...

192 LLE Review, Volume 95 An ion-implantation technique has been employed in the GaAs photodetector technology to obtain materials with a carrier lifetime in the picosecond and even subpicosecond regimes. Properties of proton,1 Ar+,2,3 As+,4–6 and other ion-implanted GaAs have been investigated thoroughly. Nitrogen-ion–implanted GaAs (N+-GaAs) is a relatively new member in the family of ion-imp...

INTRODUCTION Free or low-cost HIV testing, condoms, and lubricants are foundational HIV prevention strategies, yet are often inaccessible for men who have sex with men (MSM). In the global context of stigma and poor healthcare access, transgender (trans) MSM may face additional barriers to HIV prevention services. Drawing on data from a global survey of MSM, we aimed to describe perceived acces...

BACKGROUND Men having sex with men (MSM) remain the largest high-risk group involved in on-going transmission of sexually transmitted infections (STI), including HIV, in the Netherlands. As risk behaviour may change with age, it is important to explore potential heterogeneity in risks by age. To improve our understanding of this epidemic, we analysed the prevalence of and risk factors for selec...

In this paper, we examine the leptonic flavor invariants in minimal seesaw model (MSM), which only two right-handed neutrino singlets are added into Standard Model order to accommodate tiny masses and explain cosmological matter-antimatter asymmetry via leptogenesis mechanism. For first time, calculate Hilbert series (HS) for MSM. With HS demonstrate that there totally 38 basic invariants, amon...

BACKGROUND The prevalence of HIV in Ghana is 1.3%, compared to 17% among men who have sex with men (MSM). There is limited empirical data on the current health care climate and its impact on HIV prevention services for Ghanaian MSM. The purposes of this study were to investigate (1) MSM's experiences using HIV prevention resources, (2) what factors, including health care climate factors, influe...

In recent years, the population of men who have sex with men (MSM) have become the most significant increasing group of HIV-1 transmission in China. To identify new recombinant strains and transmission patterns of HIV-1 in Chinese MSM population, a cross-sectional investigation of MSM in Anhui Province (in south-eastern China) was performed in 2011. The diagnosed AIDS case rate, CD4 T-cell coun...

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...
