Association between the Combination of Speed-Eating and Eating until Full and Overweight/Obesity in Part-Time High School Students.

Introduction: This cross-sectional study aimed to examine the association between overweight/obesity and the combined behavior of speed-eating and eating until full among part-time high school students.

Methods: In 2015, 2,507 male and female part-time high school students from Hyogo Prefecture, Japan, who completed a self-reported questionnaire on lifestyle, were included in the analysis. Overweight/obesity was defined as a body mass index of 25 kg/m2 or more.

Natto Intake is Inversely Associated with Osteoporotic Fracture Risk in Postmenopausal Japanese Women.

Background: The direct association between intake of Japanese fermented soybeans, namely natto, and bone mineral density (BMD) is known. However, the association with osteoporotic fractures has not been studied.

Objective: This study aimed to investigate whether habitual natto intake is associated with a risk of osteoporotic fractures.

Blue-light regulation of ZmPHOT1 and ZmPHOT2 gene expression and the possible involvement of Zmphot1 in phototropism in maize coleoptiles.

ZmPHOT1 and ZmPHOT2 are expressed differentially in maize coleoptiles and leaves, with Zmphot1 possibly involved in first-positive phototropic curvature of red-light-adapted maize coleoptiles exposed to pulsed low-fluence blue light. Unilateral blue-light perception by phototropin(s) is the first event of phototropism, with the subsequent signal causing lateral transport of auxin at the coleoptile tip region of monocots. In this study, we analyzed the behavior of two maize phototropin genes: ZmPHOT1 and ZmPHOT2, the latter identified from the maize genome database and newly characterized.

Redox potentials of primary electron acceptor quinone molecule (QA)- and conserved energetics of photosystem II in cyanobacteria with chlorophyll a and chlorophyll d.

In a previous study, we measured the redox potential of the primary electron acceptor pheophytin (Phe) a of photosystem (PS) II in the chlorophyll d-dominated cyanobacterium Acaryochloris marina and a chlorophyll a-containing cyanobacterium, Synechocystis. We obtained the midpoint redox potential (E(m)) values of -478 mV for A. marina and -536 mV for Synechocystis.
