Look into the HIV Epidemic of Gay Community with a Socio-Cultural Perspective: A Qualitative Study in China, 2015-2016.

Background: Current Chinese studies continue to view male homosexuality through a disease focused lens which pays limited attention to socio-cultural aspects of sexual behavior and HIV transmission. This qualitative study aimed to investigate how socio-cultural factors influence gay men's sexual beliefs and behaviors in contemporary China, and their implications for HIV epidemic.

Methods And Findings: Qualitative methodology was used in this study.

Partner notification in cooperation with community-based organizations among HIV-positive men who have sex with men in two Chinese cities.

The epidemic of HIV/AIDS among Chinese men who have sex with men (MSM) is rapidly escalating. We implemented partner notification among HIV-infected MSM, cooperating with MSM-serving community-based organizations (CBOs) in two Chinese cities from June 2014 to May 2015. CBOs participated in identifying new HIV-positive MSM utilizing rapid HIV tests and partner notification among index cases.

Gaps between calcium recommendations to prevent pre-eclampsia and current intakes in one hospital in Argentina.

Background: Hypertensive disorders are a major cause of maternal mortality. In Latin America and the Caribbean, pre-eclampsia accounts for approximately one in every four maternal deaths. The World Health Organization recommends calcium supplementation during pregnancy for the prevention and treatment of pre-eclampsia and eclampsia in locations where dietary calcium intake is low.

Behavioral differences among C57BL/6 substrains: implications for transgenic and knockout studies.

Separate breeding colonies of C57BL/6 ("B6") mice maintained at the Jackson Laboratories ("J") and NIH ("N") have led to the emergence of two distinct substrains of C57BL/6 mice: C57BL/6J and C57BL/6N. Molecular genetic studies indicate simple sequence-length polymorphisms, single-nucleotide polymorphisms, and copy-number variants among B6 substrains that may contribute to phenotypic differences. We examined differences in motor coordination, pain sensitivity, and conditional fear in the C57BL/6J strain and three N strains: C57BL/6NCrl (Charles River), C57BL/6NTac (Taconic), and C57BL/6NHsd (Harlan Sprague Dawley).
