Twelve cases of suspected impaired driving are discussed in which the drivers who subsequently tested positive for synthetic cannabinoid drugs underwent a psychophysical assessment. The attitude of the drivers was described as cooperative and relaxed, speech was slow and slurred and coordination was poor. Pulse and blood pressure were generally elevated. Horizontal gaze nystagmus was assessed i...

Road traffic crashes are a significant cause of the disease burden among children, with the highest mortality in low- and middle-income countries. This observational study explores such injuries in Cape Town, South Africa through an analysis of data for cases in 1992, 2002 and 2012 at the Red Cross War Memorial Children's Hospital, a referral paediatric hospital for children younger than 13 yea...

A main objective of ethnobotany is to document traditional knowledge about plants before it disappears. However, little is known about the coverage of past ethnobotanical studies and thus about how well the existing literature covers the overall traditional knowledge of different human groups. To bridge this gap, we investigated ethnobotanical data-collecting efforts across four countries (Colo...

The World Health Organization reported that inappropriate feeding in children is responsible for one-third of the cases of malnutrition. This cross-sectional study aimed to determine the prevalence of malnutrition and identify the relationship between feeding practices and malnutrition in children below 5 years, in 7 remote and poor counties of China. A sample of 2201 children and 1978 caregive...

Quantitative detection of metabolites is a highly desirable feature in metabolome analyses. Recently, the successful detection of multiple metabolites using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) in the negative ion mode employing 9-aminoacridine as the organic matrix was reported (Edwards JL, Kennedy RT. Anal. Chem. 2005; 77: 2201-2209). However, there is litt...

GATA-1 controls hematopoietic development by activating and repressing gene transcription, yet the in vivo mechanisms that specify these opposite activities are unknown. By examining the composition of GATA-1–associated protein complexes in a conditional erythroid rescue system as well as through the use of tiling arrays we detected the SCL/TAL1, LMO2, Ldb1, E2A complex at all positively acting...
