Grain amaranth (Amaranthus hypochondriacus L.) is abundant in oxalate and can secrete oxalate under aluminium (Al) stress. However, the features of Al-induced secretion of organic acid anions (OA) and potential genes responsible for OA secretion are poorly understood. Here, Al-induced OA secretion in grain amaranth roots was characterized by ion charomatography and enzymology methods, and suppr...

It is generally accepted that butterfly wing color-patterns have ecological and behavioral functions that evolved through natural selection. However, particular wing color-patterns may be produced physiologically in response to environmental stress, and they may lack significant function. These patterns would represent an extreme expression of phenotypic plasticity and can eventually be fixed g...

introduction: the aim of this study was to evaluate the effect of proximal contour of class ii composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. methods: in order to evaluate the stress distribution of class ii composite restorations using finite element method, upper ...

It has been hypothesized that myofiber orientation adapts to achieve a preferred mechanical loading state in the myocardial tissue. Earlier studies tested this hypothesis in a combined model of left ventricular (LV) mechanics and remodeling of myofiber orientation in response to fiber cross-fiber shear, assuming synchronous timing of activation and uniaxial active stress development. Difference...

This paper presents some preliminary data from the first time point of a longitudinal study that is looking at precursors to language development in typically developing infants, and infants with Down syndrome. The skill of interest in this paper is speech segmentation ability, which refers to an infant’s ability to segment and recognise words embedded in fluent speech. Using the preferential l...

The TET enzymes convert methylcytosine to the newly discovered base hydroxymethylcytosine. While recent reports suggest that TETs may play a role in response to oxidative stress, this role remains uncertain, and results lack in vivo models. Here we show a global decrease of hydroxymethylcytosine in cells treated with buthionine sulfoximine, and in mice depleted for the major antioxidant enzymes...

Aim: The aim of this study was to investigate the relationship between sleep of healthy infants and their mother’s parenting stress in Japan. Methods: Cross-sectional study. Data obtained from 48 healthy mothers and their infants aged from 6-month old to 24-month old were studied. The mothers completed questionnaires including the Parenting Stress Index Short Form (PSI Short Form), and infant’s...

The ability of listeners to distinguish between compound and phrasal stress in English was examined on the basis of a picture selection task. The responses to naturally and synthetically produced stimuli were compared. While greater overall accuracy was observed with the natural stimuli, the same pattern of greater accuracy with compound stress than with phrasal stress was observed with both ty...

Pattern glare is characterised by symptoms of visual perceptual distortions and visual stress on viewing striped patterns. People with migraine or Meares-Irlen syndrome (visual stress) are especially prone to pattern glare. The literature on pattern glare is reviewed, and the goal of this study was to develop clinical norms for the Wilkins and Evans Pattern Glare Test. This comprises three test...
