TCP7 interacts with Nuclear Factor-Ys to promote flowering by directly regulating SOC1 in Arabidopsis.

The success of plant reproduction depends on the timely transition from the vegetative phase to reproductive growth, a process often referred to as flowering. Although several plant-specific transcription factors belonging to the Teosinte Branched 1/Cycloidea/Proliferating Cell Factor (TCP) family are reportedly involved in the regulation of flowering in Arabidopsis, the molecular mechanisms, especially for Class I TCP members, are poorly understood. Here, we genetically identified Class I TCP7 as a positive regulator of flowering time.

Impact of periodontal disease and chewing ability on the quality of life of the elderly in an affluent community.

Background/purpose: Improvement of the medical and social environment is an important aspect of government policies in assuring the quality of life (QoL) of older adults. However, few studies have appraised the impact and relationship of QoL with clinical factors among elderly individuals in affluent residential areas.

Methods: A total of 166 older adults from Chang Gung Health and Culture Village were enrolled.

Improving Mechanical Properties of PVPPA Welded Joints of 7075 Aluminum Alloy by PWHT.

In this study, 7075 aluminum alloy with a thickness of 10 mm was successfully welded with no obvious defects by pulsed variable polarity plasma arc (PVPPA) welding. The mechanical properties of PVPPA welded joints have been researched by post weld heat treatment (PWHT). The results indicate that the heat treatment strongly affects the mechanical properties of the welded joints.
