China's little-known efforts to protect its marine ecosystems safeguard some habitats but omit others.

China’s stature as the world’s major producer and consumer of seafood is legendary, but its long-standing tradition of protecting marine life domestically is virtually unknown. We present the most comprehensive database on area-based marine conservation in China including 326 sites that conserve 12.98% of China’s seas and address 142 conservation objectives.

Short duration of marriage at conception as an independent risk factor for schizophrenia.

Unlabelled: Short duration of marriage (DoM) is a risk factor for preeclampsia that is also related to the risk for schizophrenia. This analysis examined the risk for schizophrenia associated with DoM and its independence from parental psychiatric disorders, parental ages and fathers' age at marriage.

Method: Relative Risks (RR) for schizophrenia were estimated using continuous and stratified Cox proportional hazards models in the 90,079 offspring from the prospective population-based Jerusalem birth cohort study (1964-1976).

The Emerging Role for Zinc in Depression and Psychosis.

Zinc participation is essential for all physiological systems, including neural functioning, where it participates in a myriad of cellular processes. Converging clinical, molecular, and genetic discoveries illuminate key roles for zinc homeostasis in association with clinical depression and psychosis which are not yet well appreciated at the clinical interface. Intracellular deficiency may arise from low circulating zinc levels due to dietary insufficiency, or impaired absorption from aging or medical conditions, including alcoholism.

Live birth sex ratios and father's geographic origins in Jerusalem, 1964-1976.

Objective: To examine whether ancestry influenced sex ratios of offspring in a birth cohort before parental antenatal sex selection influenced offspring sex.

Methods: We measured the sex ratio as the percent of males according to countries of birth of paternal and maternal grandfathers in 91,459 live births from 1964 to 1976 in the Jerusalem Perinatal Study. Confidence limits (CI) were computed based on an expected sex ratio of 1.
