Coronal STIR MRI sequences in unexplained limping in children under 6 years old: A single-center retrospective study of 130 cases.

Introduction: Limping is a common presenting symptom in young children. Clinical examination backed up by laboratory analysis, standard radiography, and/or ultrasound may fail to determine the diagnosis, and limping may prove persistent, requiring repeated consultation. Magnetic resonance imaging (MRI) can suggest the etiology or provide welcome reassurance when normal.

Tap Water Consumption Is Associated with Schoolchildren's Cognitive Deficits in Afghanistan.

Environmental influence on intelligence quotient (IQ) is poorly understood in developing countries. We conducted the first cross-sectional investigation to assess the role of socio-economic and environmental factors on schoolchildren's IQ in Jalalabad, Afghanistan. A representative sample of 245 schoolchildren aged 7-15 was randomly selected in five schools.

Pollutant Pb burden in Mediterranean Centroscymnus coelolepis deep-sea sharks.

We report lead (Pb) analyses in juvenile (n = 37; mean length = 24.7 ± 2.3 cm) and adult (n = 16; mean length = 52.

Cyanine platelet single crystals: growth, crystal structure and optical spectra.

Crystalline organic semiconducting materials are much in demand for multiple electronic and optoelectronic device applications. Here, solution grown ultrathin rhombic crystals of a trimethine carbocyanine anionic dye are used to establish relationships between structural and optical properties. The dye crystallized in the monoclinic space group P21/c featuring alternating layers of molecules in two different herringbone type patterns, with perchlorate counterions located mostly within one of the two layers.
