Initial negative emotionality, but not depressive symptoms,...

Abstract Aims Test the effects of root drying on biomechanical properties fibrous roots. Methods Tensile strength and Young’s modulus Festuca arundinacea roots were tested after full hydration during progressive drying. Root diameter, water loss, content measured for all treatments. Results Hydrated showed weak relations between diameter. After only 30 min air-drying, both tensile increased sig...

Subjective memory complaints (SMCs) are part of the diagnostic criteria for Mild Cognitive Impairment (MCI), yet little is known about their etiology.
