Deletion of sphingosine kinase 1 ameliorates hepatic steatosis in diet-induced obese mice: Role of PPARγ
Publisher: Elsevier BV
Date: 02-2016
DOI: 10.1016/J.BBALIP.2015.11.006
Abstract: Sphingolipid metabolites have emerged playing important roles in the pathogenesis of nonalcoholic fatty liver disease, whereas the underlying mechanism remains largely unknown. In the present study, we provide both in vitro and in vivo evidence showing a pathogenic role of sphingosine kinase 1 (SphK1) in hepatocellular steatosis. We found that levels of SphK1 expression were significantly increased in steatotic hepatocytes. Enforced overexpression of SphK1 or treatment with sphingosine 1-phosphate (S1P) markedly enhanced hepatic lipid accumulation. In contrast, the siRNA-mediated knockdown of SphK1 or S1P receptors, S1P2 and S1P3, profoundly inhibited lipid accumulation in hepatocytes. Moreover, Sphk1(-/-) mice exhibited a significant amelioration of hepatosteatosis under diet-induced obese (DIO) conditions, compared to wild-type littermates. In addition, DIO-induced up-regulation of PPARγ and its target genes were significantly reduced by SphK1 deficiency. Furthermore, treatment of hepatocytes with S1P induces a dose-dependent increase in PPARγ expression at the transcriptional level. Blockage of S1P receptors and the Akt-mTOR signaling profoundly inhibited S1P-induced PPARγ expression. Notably, down-regulation of PPARγ by using its siRNA significantly diminished the pro-steatotic effect of SphK1/S1P. Thus, the study demonstrates a new pathway connecting SphK1 and PPARγ involved in the pathogenesis of hepatocellular steatosis.

Consonantal timing and release burst acoustics distinguish multiple coronal stop place distinctions in Wubuy (Australia)
Publisher: Acoustical Society of America (ASA)
Date: 10-2016
DOI: 10.1121/1.4964399
Abstract: Substantial research has established that place of articulation of stop consonants (labial, alveolar, velar) are reliably differentiated using a number of acoustic measures such as closure duration, voice onset time (VOT), and spectral measures such as centre of gravity and the relative energy distribution in the mid-to-high spectral range of the burst. It is unclear, however, whether such measurable acoustic differences are present in multiple place of articulation contrasts among coronal stops. This article presents evidence from the highly endangered indigenous Australian language Wubuy, which maintains a 4-way coronal stop place contrast series in all word positions. The authors examine the temporal and burst characteristics of /t̪ t ʈ/ in three prosodic positions (utterance-initial, word-initial but phrase medial, and word-medial). The results indicate that VOT, closure duration, and the spectral quality of the burst may indeed differentiate multiple coronal place contrasts, in most positions, although measures that distinguish the apical contrast in absolute initial position remain elusive. The authors also examine measures (spectrum kurtosis, spectral tilt) previously used in other studies of multiple coronals in Australian languages. These results suggest that the authors' measures perform at least as well as those previously applied to multiple coronals in other Australian languages.

Lexical change in pre-colonial Australia
Publisher: John Benjamins Publishing Company
Date: 05-10-2011
Abstract: Current analyses present lexical borrowing as a pervasive phenomenon in pre-colonial Australia. They propose that this follows from the high levels of multilingualism and language group exogamy which characterized pre-colonial sociality. This article shows that lexical borrowing was not pervasive in Australia, arguing that there is no necessary or even default relation between high levels of multilingualism and language group exogamy, and high levels of borrowing. These social phenomena may equally be accompanied by extremes of lexical differentiation between languages. Australia provides many ex les of such differentiation. The paper also argues that there are no ex les of the borrowing of lexical material from irregular paradigms in Australia. As such, the sharing of lexical material from irregular paradigms is a reliable guide to genetic relations in Australia.

Reconstructing remote relationships
Publisher: John Benjamins Publishing Company
Date: 31-12-2017
Abstract: Evaluation of hypotheses on genetic relationships depends on two factors: database size and criteria on correspondence quality. For hypotheses on remote relationships, databases are often small. Therefore, detailed consideration of criteria on correspondence quality is important. Hypotheses on remote relationships commonly involve greater geographical and temporal ranges. Consequently, we propose that there are two factors which are likely to play a greater role in comparing hypotheses of chance, contact and inheritance for remote relationships: (i) spatial distribution of corresponding forms and (ii) language specific unpredictability in related paradigms. Concentrated spatial distributions disfavour hypotheses of chance, and discontinuous distributions disfavour contact hypotheses, whereas hypotheses of inheritance may accommodate both. Higher levels of language-specific unpredictability favour remote over recent transmission. We consider a remote relationship hypothesis, the Proto-Australian hypothesis. We take noun class prefixation as a test dataset for evaluating this hypothesis against these two criteria, and we show that inheritance is favoured over chance and contact.

From prefixes to suffixes
Publisher: John Benjamins Publishing Company
Date: 15-12-2006
Abstract: This article provides a counterex le to the commonly held, if unexamined, proposition that morphemes reconstructed as affixes do not change their position with respect to the root. We do not expect to find that a proto-prefix has suffix reflexes, nor that a proto-suffix has prefix reflexes. In this paper we show, through detailed reconstruction, that paradigms of class/case suffixes in a number of Northern Australian languages derive historically from a paradigm of proto-prefixes, through the encliticization and reduction of prefixed demonstratives to nominals. This process has only left a few traces of the demonstrative stems in the synchronic forms.
Biological defleecing: intravenous infusion of amino acid mixtures lacking lysine and methionine creates a weakened zone in the wool staple, which is amenable to mechanical wool harvesting
Publisher: CSIRO Publishing
Date: 2015
DOI: 10.1071/AN14137
Abstract: Conventional shearing of sheep is labour-intensive, expensive and presents significant occupational health and safety risks. The only alternative at present is based on injection of epidermal growth factor, which severs the fibre at the follicle level. This technology cannot be used in pregnant animals and requires application of a net to retain the severed fleece. An alternative is to create a weakened zone within the wool staple, which would be sufficiently strong to retain the fleece on the sheep while a protective covering regrows, but sufficiently weak as to allow painless and automated removal of the fleece. We demonstrate that this approach is possible using mixtures of amino acids lacking lysine and methionine. Initially we demonstrate the relationships between staple strength, a subjective ‘harvestability’ score and a subjective ‘pain’ score, using fleeces from animals treated with varying levels of cortisol to create a wide range of strengths of wool attachment. We assigned a score to the ease with which we could manually break the staples, and also to the animal’s response to breaking the staples still attached to the skin. The relationships between these variables indicated that a staple was considered harvestable and could be removed with minimal skin flinch response at a staple strength of ~10–13 N/kTex. Staples within this range were then produced by intravenous infusion of mixtures of amino acids lacking in lysine and methionine for a 5-day period. The weak point was uniformly created across the entire fleece and when a prototype roller-pin device was applied to the weakened wool, it uniformly broke the fleece of the three sheep tested. The mode of action of the amino acid treatment on wool growth was studied. There was no effect of unbalanced amino acids on the rate of follicle bulb cell ision, the number of active wool follicles, or the length of the keratinisation zone in the wool follicle. Fibre diameter was reduced by ~4 microns by treatment, and intrinsic fibre strength (strength relative to cross-sectional area of the wool fibres), was reduced by ~50%. Results of these trials are encouraging but further work is required to develop a practical, on-farm method of altering systemic amino acid supply and to design an automated, high-throughput system of severing the weakened wool.

Complex Predicates
Publisher: Cambridge University Press
Date: 22-04-2010
Abstract: Complex predicates are multipredicational, but monoclausal structures. They have proven problematic for linguistic theory, particularly for proposed distinctions between the lexicon, morphology, and syntax. This volume focuses on the mapping from morphosyntactic structures to event structure, and in particular the constraints on possible mappings. The volume showcases the 'coverb construction', a complex predicate construction which, though widespread, has received little attention in the literature. The coverb construction contrasts with more familiar serial verb constructions. The coverb construction generally maps only to event structures like those of monomorphemic verbs, whereas serial verb constructions map to a range of event structures differing from those of monomorphemic verbs. The volume coverage is truly cross-linguistic, including languages from Australia, Papua New Guinea, Southeast Asia, the Indian subcontinent, East Africa and North America. The volume establishes a new arena of research in event structure, syntax, and cross-linguistic typology.

Vowel-length in Warray and weight identity
Publisher: Cambridge University Press (CUP)

DOI: 10.1017/S0952675797003400
Abstract: Correspondence is a relation between one representation and another (McCarthy & Prince 1993, 1994, 1995). This relationship may be between an underlying or lexical representation and a surface representation, that is: Input–Output forms or between surface forms such as a reduplicant and its base (McCarthy & Prince 1995) or other derivationally related pairs (see for ex le Benua 1995, McCarthy 1995, Kenstowicz 1996) – i.e. Output–Output. Correspondence constraints over related words in a paradigm ensure uniformity within the paradigm. In earlier theories this effect was ensured by the Strict Cycle Constraint, which forbade structure-changing operations except in immediately derived environments and thus ensured that most of the base word stayed the same in derivation. In this paper we show that correspondence between derivationally related output forms (Benua 1995) is essential for the proper analysis of vowel length in Warray, a language of Northern Australia spoken near Darwin, and superior to an account making use of cyclicity. Correspondence constraints ensuring identity between output forms explain the pattern of vowel length in nouns, predicting both where long vowels occur as well as the apparently anomalous appearance of short vowels where long vowels might be expected.

Acoustic characteristics of Punjabi retroflex and dental stops
Publisher: Acoustical Society of America (ASA)
Date: 06-2017
DOI: 10.1121/1.4984595
Abstract: The phonological category “retroflex” is found in many Indo-Aryan languages however, it has not been clearly established which acoustic characteristics reliably differentiate retroflexes from other coronals. This study investigates the acoustic phonetic properties of Punjabi retroflex /ʈ/ and dental /ʈ̪/ in word-medial and word-initial contexts across /i e a o u/, and in word-final context across /i a u/. Formant transitions, closure and release durations, and spectral moments of release bursts are compared in 2280 stop tokens produced by 30 speakers. Although burst spectral measures and formant transitions do not consistently differentiate retroflexes from dentals in some vowel contexts, stop release duration, and total stop duration reliably differentiate Punjabi retroflex and dental stops across all word contexts and vocalic environments. These results suggest that Punjabi coronal place contrasts are signaled by the complex interaction of temporal and spectral cues.

Vowel acoustics reliably differentiate three coronal stops of Wubuy across prosodic contexts
Publisher: Walter de Gruyter GmbH
Date: 25-01-2012
DOI: 10.1515/LP-2012-0009
Abstract: The present study investigates the acoustic differentiation of three coronal stops in the indigenous Australian language Wubuy. We test independent claims that only VC (vowel-into-consonant) transitions provide robust acoustic cues for retroflex as compared to alveolar and dental coronal stops, with no differentiating cues among these three coronal stops evident in CV (consonant-into-vowel) transitions. The four-way stop distinction /t, t̪, ʈ, c/ in Wubuy is contrastive word-initially (Heath 1984) and by implication utterance-initially, i.e., in CV-only contexts, which suggests that acoustic differentiation should be expected to occur in the CV transitions of this language, including in initial positions. Therefore, we examined both VC and CV formant transition information in the three target coronal stops across VCV (word-internal), V#CV (word-initial but utterance-medial) and ##CV (word- and utterance-initial), for /а/ vowel contexts, which provide the optimal environment for investigating formant transitions. Results confirm that these coronal contrasts are maintained in the CVs in this vowel context, and in all three positions. The patterns of acoustic differences across the three syllable contexts also provide some support for a systematic role of prosodic boundaries in influencing the degree of coronal stop differentiation evident in the vowel formant transitions.
