Abstract:

Abstract Hermansky-Pudlak syndrome (HPS), a disorder of organelle biogenesis, affects lysosomes, melanosomes, and platelet dense bodies. Seven genes cause HPS in humans (HPS1-HPS7) and at least 15 nonallelic mutations cause HPS in mice. Where their function is known, the HPS proteins participate in protein trafficking and vesicle docking/fusion events during organelle biogenesis. HPS-associated genes participate in at least 4 distinct protein complexes: the adaptor complex AP-3; biogenesis of lysosome-related organelles complex 1 (BLOC-1), consisting of 4 HPS proteins (pallidin, muted, cappuccino, HPS7/sandy); BLOC-2, consisting of HPS6/ruby-eye, HPS5/ruby-eye-2, and HPS3/cocoa; and BLOC-3, consisting of HPS1/pale ear and HPS4/light ear. Here, we report the cloning of the mouse HPS mutation reduced pigmentation (rp). We show that the wild-type rp gene encodes a novel, widely expressed 195-amino acid protein that shares 87% amino acid identity with its human orthologue and localizes to punctate cytoplasmic structures. Further, we show that phosphorylated RP is part of the BLOC-1 complex. In mutant rp/rp mice, a premature stop codon truncates the protein after 79 amino acids. Defects in all the 5 known components of BLOC-1, including RP, cause severe HPS in mice, suggesting that the subunits are nonredundant and that BLOC-1 plays a key role in organelle biogenesis.

Abstract:

Hedysarum polybotrys polysaccharide (HPS) is the principal active fraction responsible for the antidiabetic properties of this species. The aim of this study was to determine the antidiabetic properties of 4 purified fractions of different molecular weight range HPSs (HPS1, HPS2, HPS3, HPS4). HPS3 was selected for examination of its hypoglycemic mechanism because of its significant hypoglycemic effect in alloxan-induced diabetic mice. The changes in blood glucose levels and oral glucose tolerance tests (OGTT) showed that hypoglycemia was more pronounced in HPS3-treated groups than in the diabetes mellitus model (DM) control group. The interleukin-6, tumor necrosis factor-α, leptin, and free fatty acid levels were significantly lower in the HPS3-treated groups and HPS3 + metformin (HPS3+MET) group than in the DM control group, while plasma insulin, hepatic glycogen, superoxide dismutase, and nitric oxide synthetase activity were significantly higher. Treatment with HPS3 or HPS3+MET also significantly lowered malonaldehyde levels compared with the DM control group, while it elevated the nitric oxide and total antioxidant capacity. HPS3 altered the plasma lipid levels by lowering cholesterol and triglyceride concentrations, while elevating the plasma high-density lipoprotein cholesterol level. Therefore, these results suggest that HPS3 may partly ameliorate hyperglycemia and hyperlipidemia associated with type 2 diabetes through increased insulin secretion, inhibition of lipid peroxidation, promotion of sensitivity to insulin, suppression of gluconeogenesis and reduction in the biosynthesis fatty acid, cholesterol and cell cytokines related to insulin resistance, and it could be a useful adjunct therapy to a proven first-line therapy for type 2 diabetes using metformin.

Abstract:

Abstract Abstract 3286 Background: Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder causing oculocutaneous albinism, bleeding disorder and ceroid lipofuscinosis. Platelets from HPS patients are characterized by impaired secretion of dense (δ)-bodies (CD63). Neutropenia and susceptibility to recurrent infections were exclusively observed in HPS2 patients so far. There are eight known human HPS genes (HPS1-HPS8), each leading to a particular clinical HPS subtype (HPS1-HPS8). Patients/Results: The patients show a typical HPS phenotype concerning oculocutaneous albinism and bleeding symptoms. In vivo-, in vitro bleeding time and platelet aggregometry analyses revealed impaired platelet function. We identified HPS3 in two Turkish brothers and HPS2 in a girl from the United Emirates. Both brothers with HPS3 demonstrated absence of platelet δ-granule secretion measured by flow cytometry analysis. A novel 1 bp-deletion in the HPS3 gene was identified in both brothers. In addition, one brother with HPS3 demonstrated psychomotoric retardation. MRI scan revealed cranial gliosis. Interestingly, array-CGH analysis revealed a 0.7 Mb deletion on chromosome 17 which had not been identified in the other brother and which seems to have caused the cranial gliosis. The girl with HPS2 suffered from life-threatening bleeding after tonsillectomy leading to severe asphyxia, resuscitation and finally, to mental retardation. Flow cytometry analysis demonstrated impaired platelet δ-granule secretion with a typical pattern for HPS2. CD63 expression was already increased on resting platelets, but there was only little increase after thrombin stimulation. Interestingly, only a NK-CD107 partial degranulation defect was diagnosed. So far, clinical symptoms of immunodeficiency are not obvious. Molecular genetic analyses revealed a novel 2 bp-deletion in the last exon of HPS2 leading to a frameshift and a prolonged altered protein. The location of the deletion at the very C-terminal end may prevent a complete loss of the HPS2 protein leading to a less pronounced severity of immunodeficiency as in other HPS2 patients. Conclusion: Patients with oculocutaneous albinism should be investigated for increased clinical bleeding symptoms. In case of increased bleeding symptoms, analyses of primary hemostasis should be initiated to confirm HPS. Using flow cytometry analyses HPS2 can be distinguished from the other subtypes of HPS. Molecular genetic investigations should be performed to differentiate the various subtypes of HPS which is important for therapy and prognosis. The HPS3 patient`s mental retardation seemed to be caused by an additional deletion. The identification of the molecular genetic defect helps to understand the patients` various clinical phenotypes.

Abstract:

This article presents an HPSG parser using a technique called CFG filtering. The parser predicts possible parse trees using a CFG generated automatically from a given HPSG-based grammar. Parsing costs are reduced because unification is applied only to the predicted parse trees. In other words, parsing is speeded up because the parser avoids unnecessary unification by eliminating impossible parse trees. We show the method for generating a CFG from an HPSG-based grammar and outline a parsing scheme using the CFG. The effectiveness of the parsing scheme is shown through experimental results obtained by using several HPSG-based grammars, including the LinGO grammar.

Abstract:

Objectives: In a context where sleep laboratories are overwhelmed by a growing demand to diagnose obstructive sleep apnea syndrome (OSAS), efficient substitutive solutions to in-laboratory polysomnography should be found. To compare the effectiveness and costs of home unattended polysomnography (Hpsg) and telemonitored polysomnography (TMpsg), a cost minimization study was performed.Methods: In a crossover trial, 99 patients underwent on two consecutive nights TMpsg and Hpsg according to a randomized order. A legibility recording criterion was retained to measure effectiveness. A microcosting study of TMpsg and Hpsg was performed. The risks to adopt home strategy or telemonitored strategy, according to different scenario chosen to reach the diagnosis in case of failure of Hpsg or TMpsg, were analyzed.Results: The recording was considered to be ineffective in 11.2% of TMpsg (95% CI, 4.9–17.4) and in 23.4% (95% CI, 19.12–27.68) of Hpsg. The effectiveness differential was 12.2% (95% CI, 1.8–22.6) (p = .02). Assuming that in case of failure PSGs would be re-realized in the same condition to reach the diagnosis, then TMpsg could be selected if Hc/TMc (cost of Hpsg/cost of TMpsg) > 0.97; Hpsg could be selected if Hc/TMc < 0.76. If 0.76 ≤ Hc/TMc ≤ 0.97, the choice of TMpsg would be ambiguous. TMc was estimated to be $244, while Hc was $153 (Hc/TMc = 0.63).Conclusion: Unless some specific geographical situations generate significant transport costs, the implementation of a strategy based on unattended polysomnography at home is cost-saving compared to a telemonitoring strategy.

Abstract:

The aim was to determine whether strength training with machines vs. functional strength training at 80% of one-repetition maximum improves muscle strength and power among the elderly. Sixty-three subjects (69.9 ± 4.1 yr) were randomized to a high-power strength group (HPSG), a functional strength group (FSG), or a nonrandomized control group (CG). Data were collected using a force platform and linear encoder. The training dose was 2 times/wk, 3 sets × 8 reps, for 11 wk. There were no differences in effect between HPSG and FSG concerning sit-to-stand power, box-lift power, and bench-press maximum force. Leg-press maximum force improved in HPSG (19.8%) and FSG (19.7%) compared with CG (4.3%;p= .026). Bench-press power improved in HPSG (25.1%) compared with FSG (0.5%,p= .02) and CG (2%,p= .04). Except for bench-press power there were no differences in the effect of the training interventions on functional power and maximal body strength.

Abstract:

This paper investigates the status of the lexicon and the possibilities for expressing lexical generalizations in the paradigm of Head-Driven Phrase Structure Grammar (HPSG). We illustrate that the architecture readily supports the use of implicational principles to express generalizations over a class of word objects. A second kind of lexical generalizations expressing relations between classes of words is often expressed in terms of lexical rules. We show how lexical rules can be integrated into the formal setup for HPSG developed by King (1989, 1994), investigate a lexical rule specification language allowing the linguist to only specify those properties which are supposed to differ between the related classes, and define how this lexical rule specification language is interpreted. We thereby provide a formalization of lexical rules as used in HPSG.

Abstract:

Welsh differs from English in a number of ways. The most obvious point is that it is a VSO language, but it also has distinctive agreement phenomena and clitics. For this reason, it is natural to ask of any theory of syntax that has been developed primarily on the basis of English: how can it handle Welsh? Welsh has had fairly extensive attention within the Government-Binding theory (see, for example, Harlow, 1981; Sproat, 1985; Sadler, 1988, and Hendrick, 1988). It has also had some attention within Generalized Phrase Structure Grammar (GPSG) (see Harlow, 1983; Borsley, 1983; 1988a). In this paper, I will consider how some of the central features of Welsh can be accommodated within Head-driven Phrase Structure Grammar (HPSG). This is a framework developed over the last few years by Carl Pollard, Ivan Sag and others, which seeks to combine the insights of GPSG, categorial grammar and certain other theories (see Pollard, 1985, 1988; Sag & Pollard, 1987, and Pollard & Sag, 1988). In fact, I will be mainly concerned with the version of HPSG developed in Borsley (1986, 1987, 1988 b), but I will also have something to say about standard HPSG.

Abstract:

A current limitation of the connectionist approach to second language acquisition (SLA) research is that it does not, to my knowledge, include complex linguistic representations. This article proposes a partial solution to this limitation by motivating and illustrating specific analyses that utilize the sign-based representations developed within Head-driven Phrase Structure Grammar (HPSG). To motivate the proposed representations, the article applies them to an analysis of four types of mappings between form and function: one-to-one, primed redundancy, nonprimed redundancy and polyfunctional. The paper summarizes representative SLA data that indicate how these mappings may appear in second language (L2) production. Key properties of HPSG analyses are discussed, indicating how they are consistent with connectionist assumptions. Sign-based representations of the four types of mappings are then provided, including several modifications to HPSG formalisms. The article concludes with a discussion of future directions.

Abstract:

Abstract Lysosome-related organelles (LROs) are a category of secretory organelles enriched with ions such as calcium, which are maintained by ion transporters or channels. Homeostasis of these ions is important for LRO biogenesis and secretion. Hermansky-Pudlak syndrome (HPS) is a recessive disorder with defects in multiple LROs, typically platelet dense granules (DGs) and melanosomes. However, the underlying mechanism of DG deficiency is largely unknown. Using quantitative proteomics, we identified a previously unreported platelet zinc transporter, transmembrane protein 163 (TMEM163), which was significantly reduced in BLOC-1 (Dtnbp1sdy and Pldnpa)–, BLOC-2 (Hps6ru)–, or AP-3 (Ap3b1pe)–deficient mice and HPS patients (HPS2, HPS3, HPS5, HPS6, or HPS9). We observed similar platelet DG defects and higher intracellular zinc accumulation in platelets of mice deficient in either TMEM163 or dysbindin (a BLOC-1 subunit). In addition, we discovered that BLOC-1 was required for the trafficking of TMEM163 to perinuclear DG and late endosome marker–positive compartments (likely DG precursors) in MEG-01 cells. Our results suggest that TMEM163 is critical for DG biogenesis and that BLOC-1 is required for the trafficking of TMEM163 to putative DG precursors. These new findings suggest that loss of TMEM163 function results in disruption of intracellular zinc homeostasis and provide insights into the pathogenesis of HPS or platelet storage pool deficiency.

Abstract:

Abstract Van Trijp (2013, 2014) claims that Sign-Based Construction Grammar (SBCG) and Head-Driven Phrase Structure Grammar (HPSG) are fundamentally different from Fluid Construction Grammar (FCG). He claims that the former approaches are generative ones while the latter is a cognitive-functional one. I argue that it is not legitimate to draw these distinctions on the basis of what is done in FCG. Van Trijp claims that there are differences in the scientific model, the linguistic approach, formalization, the way constructions are seen, and in terms of processing. This paper discusses all these alleged differences. Van Trijp also claims that his cognitive-functional approach is superior in terms of completeness, explanatory adequacy, and theoretical parsimony. In order to facilitate a discussion and comparison, I introduce the reader to basic assumptions made in FCG and the analyses suggested by Van Trijp: I first deal with the representations that are used in FCG, talk about argument structure constructions, the combination operations fusion and merging that are used in FCG, I than discuss the analysis of nonlocal dependencies and show that the suggested FCG analysis is not explanatorily adequate since it is not descriptively adequate and that a full formalization of approaches with discontinuous constituents is not more parsimonious than existing HPSG analyses either. After the discussion of specific analyses, I then provide a detailed comparison of FCG and SBCG/HPSG and discuss questions like the competence/performance distinction, mathematical formalization vs. computer implementation, fuzziness and fluidity in grammars, and permissiveness of theories. I conclude that HPSG, SBCG, and FCG belong to the same family of theories and that all claims to the contrary are unjustified.

This paper addresses the issue of how information structure can be accounted for in a formal grammar of Danish. Three information structure features – topic, focus and background – are discussed, and it is shown how they are instantiated in a number of different grammatical constructions from a corpus of spoken Danish. Prosodic, syntactic and information structure constraints characterising the various constructions are represented as typed feature structures following Head-driven Phrase Structure Grammar (HPSG), and the constructions themselves are ordered in a type hierarchy. The proposed approach modifies and extends earlier HPSG-based accounts by integrating information structure as a dimension of phrasal and clausal grammar constructions.

Abstract:

This paper presents an overview of the first broad coverage grammatical description of Danish in a Typed Feature Structure (TFS) based unification formalism inspired by HPSG. These linguistic specifications encompass phenomena within inflectional morphology, phrase structure and predicate argument structure, and have been developed with a view to implementation. The emphasis on implementability and re-usability of the specifications has led to the adoption of a rather leaner formal framework than that underlying HPSG. However, the paper shows that the adoption of such a framework does not lead to a loss of expressibility, but in fact enables certain phenomena, such as the interface between morphology and syntax and local discontinuities, to be treated in a simple and elegant fashion.

Within the Head-driven Phrase Structure Grammar (HPSG) community, one part of the Base Hypothesis concerning free relatives proposed by Bresnan & Grimshaw (1978) has gained wide support, namely that free relatives are headed by the wh-phrase. The second part of the hypothesis is that the wh-phrase is base-generated, and this has not gained support. In this paper, we will consider a subset of free relative constructions, i.e. non-specific free relatives, and provide support for this second part, restated in HPSG terms as a claim that there is no filler–gap relation between a free relative pronoun filler and a gap in the sister clause of the free relative pronoun.

Abstract:

Probabilistic modeling of lexicalized grammars is difficult because these grammars exploit complicated data structures, such as typed feature structures. This prevents us from applying common methods of probabilistic modeling in which a complete structure is divided into sub-structures under the assumption of statistical independence among sub-structures. For example, part-of-speech tagging of a sentence is decomposed into tagging of each word, and CFG parsing is split into applications of CFG rules. These methods have relied on the structure of the target problem, namely lattices or trees, and cannot be applied to graph structures including typed feature structures. This article proposes the feature forest model as a solution to the problem of probabilistic modeling of complex data structures including typed feature structures. The feature forest model provides a method for probabilistic modeling without the independence assumption when probabilistic events are represented with feature forests. Feature forests are generic data structures that represent ambiguous trees in a packed forest structure. Feature forest models are maximum entropy models defined over feature forests. A dynamic programming algorithm is proposed for maximum entropy estimation without unpacking feature forests. Thus probabilistic modeling of any data structures is possible when they are represented by feature forests. This article also describes methods for representing HPSG syntactic structures and predicate-argument structures with feature forests. Hence, we describe a complete strategy for developing probabilistic models for HPSG parsing. The effectiveness of the proposed methods is empirically evaluated through parsing experiments on the Penn Treebank, and the promise of applicability to parsing of real-world sentences is discussed.

Abstract:

This paper develops within HPSG a model of grammar with two syntactic levels, valence lists and argument structure, at which sentences may have different representations: syntactically ergative and Western Austronesian languages are distinctive by allowing different prominence orderings between the valence lists and argument structure, while forms like passives and causatives have nested argument structure lists. While binding theory and related phenomena have traditionally been described in terms of surface grammatical relations or configurations, we demonstrate that binding theory is actually correctly described in terms of argument structure configurations. Such an approach generalizes nicely over accusative and ergative constructions, correctly predicts binding patterns with causative and passive verbs, and supports the lexicality-preserving account of passives and causatives advocated within HPSG.

Abstract:

Sign-Based Construction Grammar (sbcg) is, on the one hand, a formalized version of Berkeley Construction Grammar (bcg), and, on the other hand, a further development of constructionist Head-driven Phrase Structure Grammar (hpsg). The volume edited by Hans Boas and Ivan Sag is the first book length presentation of the framework. Its centerpiece is a 130-page synopsis of the theory by Ivan Sag. The other contributions to the volume provide background, justification, case studies, an extension to diachronic syntax and a presentation of the FrameNet Constructicon. This review gives a guided tour of the framework, explaining its central notions and assumptions, as well as the notation in which they are cast. It also compares the sbcg framework with other types of Construction Grammar and with hpsg. The case studies are summarized and briefly evaluated.

Abstract:

2(S)-dihydroxypropanesulfonate (DHPS) is a microbial degradation product of 6-deoxy-6-sulfo-d-glucopyranose (sulfoquinovose), a component of plant sulfolipid with an estimated annual production of 1010tons. DHPS is also at millimolar levels in highly abundant marine phytoplankton. Its degradation and sulfur recycling by microbes, thus, play important roles in the biogeochemical sulfur cycle. However, DHPS degradative pathways in the anaerobic biosphere are not well understood. Here, we report the discovery and characterization of two O2-sensitive glycyl radical enzymes that use distinct mechanisms for DHPS degradation. DHPS-sulfolyase (HpsG) in sulfate- and sulfite-reducing bacteria catalyzes C–S cleavage to release sulfite for use as a terminal electron acceptor in respiration, producing H2S. DHPS-dehydratase (HpfG), in fermenting bacteria, catalyzes C–O cleavage to generate 3-sulfopropionaldehyde, subsequently reduced by the NADH-dependent sulfopropionaldehyde reductase (HpfD). Both enzymes are present in bacteria from diverse environments including human gut, suggesting the contribution of enzymatic radical chemistry to sulfur flux in various anaerobic niches.

Abstract:

Existing approaches to the representation of argument structure in grammar tend to focus either on semantics or on syntax. Our goal in this paper is to strike the right balance between the two levels by proposing an analysis that maintains the independence of the syntactic and semantic aspects of argument structure, and, at the same time, captures the interplay between the two levels. Our proposal is set in the context of the development of a large-scale grammar of Modern Hebrew within the framework of Head-driven Phrase Structure Grammar (HPSG). Consequently, an additional challenge it faces is to reconcile two conflicting desiderata: to be both linguistically coherentandrealistic in terms of the grammar engineering effort. We present a novel representation of argument structure that is fully implemented in HPSG, and demonstrate its many benefits to the coherence of our Hebrew grammar. We also highlight the additional dimensions of linguistic generalization that our proposal provides, which we believe are also applicable to grammars of other languages.

Abstract:

Abstract In this paper, we propose the implementation of a full-fledged feature-based lexicalist syntactic theory as a way to represent the possible configurations of features in the learner’s interlanguage and formalize a theory of acquisition based in feature reassembly. We describe gender agreement pronominal coindexation in Spanish using Head-driven Phrase Structure Grammar (HPSG) and use it to analyze the results of a self-paced reading test with L1 and L2 speakers. We find that the specification of the gender feature value at the syntactic level in epicene antecedents facilitates pronominal resolution in L1 Spanish speakers. Conversely, there is a cognitive cost when the gender feature is underspecified at the syntactic level in common gender antecedents; this cost is not found among L2 speakers. The detailed descriptions in terms of feature specification in the HPSG framework allow us to observe differences between the L1 and L2 grammars in fine-grained detail and represent optionality at the lexical level.

Abstract:

This article presents an ensemble parse approach to detecting and selecting high-quality linguistic analyses output by a hand-crafted HPSG grammar of Spanish implemented in the LKB system. The approach uses full agreement (i.e., exact syntactic match) along with a MaxEnt parse selection model and a statistical dependency parser trained on the same data. The ultimate goal is to develop a hybrid corpus annotation methodology that combines fully automatic annotation and manual parse selection, in order to make the annotation task more efficient while maintaining high accuracy and the high degree of consistency necessary for any foreseen uses of a treebank.
