[Neuropsychological development of late preterm infants and early term infants at the age of 1 year: a follow-up study].

Objective: To study the level of neuropsychological development in late preterm infants and early term infants at the age of 1 year.

Methods: A total of 1 257 children with a corrected age of 1 year were enrolled as subjects. According to gestational age at birth, they were divided into an early preterm group (28-33 weeks), a late preterm group (34-36 weeks), an early term group (37-38 weeks), and a full-term group (39-41 weeks).

Effectiveness of a Kindergarten-Based Intervention for Preventing Childhood Obesity.

Background And Objectives: Interventions to prevent childhood obesity targeting school age children have mostly reported limited effectiveness, suggesting such prevention programs may need to start at an earlier age, but evidence has been scarce. We reported a pilot study aiming to demonstrate the feasibility of a multifaceted intervention for preschool children and to provide a preliminary assessment of the effectiveness.

Methods: This nonrandomized controlled trial recruited children aged 3 to 6 years from 6 kindergartens in Guangzhou, China.

The Born in Guangzhou Cohort Study (BIGCS).

The Born in Guangzhou Cohort Study (BIGCS) is a large-scale prospective observational study investigating the role of social, biological and environmental influences on pregnancy and child health and development in an urban setting in southern China. Pregnant women who reside in Guangzhou and who attend Guangzhou Women and Children's Medical Center (GWCMC) for antenatal care in early pregnancy (<20 weeks' gestation) are eligible for inclusion. Study recruitment commenced in February 2012, with an overall participation rate of 76.

Spontaneous nanoinjection with carbon nanotubes: a molecular dynamics simulation study.

Based on the interactions between the zinc finger protein (ZNF) and single-walled carbon nanotubes (SWCNTs), we design a nanodevice for injecting ZNF spontaneously. The new injection device involves four essential components: a small-diameter SWCNT as a plunger, a large-diameter SWCNT as a tube as well as the nozzle and needle, ZNF and water solution. The injection behavior is demonstrated and analyzed using molecular dynamics simulations.

[Epidemiological study on the trend of accidental deaths among children under five in Guangzhou, 2001 - 2010].

Objective: To study the trend of accidental death among children under 5 years of age.

Methods: A survey on accidental death among children was performed in Guangzhou to compare the data from the national monitoring program on the deaths under five in the same period during 2001 - 2010. Data on mortality and causes of injures were adjusted by missing reports.

[Study on the status of unintentional injuries in children under age 7 in Guangzhou].

Objective: To understand the prevalence and distribution of unintentional injuries in children under age 7 in Guangzhou.

Methods: Data was descriptively analyzed from the Guangzhou Unintentional Injuries Surveillance System among 470 770 children under age 7 living scatter or collectively.

Results: The incidence rates of unintentional injuries among children in Guangzhou was 1.

Tea catechins induce the conversion of preformed lysozyme amyloid fibrils to amorphous aggregates.

Natural polyphenols are major constituents of plant foods and herbs. Numerous studies have demonstrated that natural polyphenols inhibited amyloid formation and destabilized the preformed amyloid fibrils. However, the molecular mechanism for the antiamyloidogenesis of polyphenols is still unclear and remains to be further explored.
