This paper presents preliminary findings of an investigation into the realisation of lexical stress in monolingual and bilingual male adolescents from a community in West Wales. Monolingual speakers of Welsh English were compared with bilinguals from Welsh-speaking and English-speaking homes. This allowed us to explore the effects of language contact and individual linguistic experience on the ...
Perception studies have long argued that phonetic confusions are more likely to happen across some phonetic features than other (e.g., place of articulation rather than manner) [1]. Similarly, we and others have noted that pronunciation variation occurs more frequently in unstressed syllables, and in syllable codas. This suggests that a phonetic information structure is at play, where for decod...
Activation of the p53 protein protects the organism against the propagation of cells that carry damaged DNA with potentially oncogenic mutations. MDM2, a p53-specific E3 ubiquitin ligase, is the principal cellular antagonist of p53, acting to limit the p53 growth-suppressive function in unstressed cells. In unstressed cells, MDM2 constantly monoubiquitinates p53 and thus is the critical step in...
We have analyzed the tissue-specific expression o f chitinase, ß-l,3-glucanase and, for com parison, phenylalanine am m onia-lyase genes in healthy, unstressed po ta to (Solanum tubero sum) plants by using R N A -R N A hybridization and im m unostaining techniques to localize the respective m R N A s and proteins in situ. P reparations o f leaf, flower, shoot tip, node and axillary bud revea...
The tumor suppressor p53 controls multiple cellular functions including DNA repair, cell cycle arrest and apoptosis. MDM2-mediated p53 ubiquitination affects both degradation and cytoplasmic localization of p53. Several cofactors are known to modulate MDM2-mediated p53 ubiquitination and proteasomal degradation. Here we show that IRTKS, a novel IRSp53-like protein inhibited p53-induced apoptosi...
Recent studies have suggested that recognition systems should concentrate their efforts on the identification of stressed syllables, as they contain disproportionately more information than do unstressed syllables. The paper investigates whether this increased informativeness may be outweighed by the informational disadvantage associated with transcribing consecutive segments within the same sy...
A comparison of the peak location in nuclear and initial prenuclear accents was carried out for two closely related dialects of Connaught Irish: Cois Fharraige and Inis Oirr. This was done across conditions where the number of unstressed syllables following the nuclear and preceding the initial prenuclear accents was varied from 2-0. Clear differences in peak timing emerged between the two dial...
As sessile organisms, plants must adapt to variations in the environment. Environmental stress triggers various responses, including growth inhibition, mediated by the plant hormone abscisic acid (ABA). The mechanisms that integrate stress responses with growth are poorly understood. Here, we discovered that the Target of Rapamycin (TOR) kinase phosphorylates PYL ABA receptors at a conserved se...
The aim of this paper is to examine effects on syllable prominence exerted by word and phrase boundaries, lexical stress, and sentence focus, and by the interactions between these factors. In a production study, German verb prefixes potentially forming prosodic minimal word pairs were systematically placed in a set of different contexts. Acoustic analyses showed a consistent effect of lexical s...
Shen T, Baker K. Venous return and clinical hemodynamics: how the body works during acute hemorrhage. Adv Physiol Educ 39: 267–271, 2015; doi:10.1152/advan.00050.2015.—Venous return is a major determinant of cardiac output. Adjustments within the venous system are critical for maintaining venous pressure during loss in circulating volume. This article reviews two factors that are thought to ena...
