https://www.readbyqxmd.com/read/28528512/working-memory-in-the-processing-of-long-distance-dependencies-interference-and-filler-maintenance
#1
Tal Ness, Aya Meltzer-Asscher
During the temporal delay between the filler and gap sites in long-distance dependencies, the "active filler" strategy can be implemented in two ways: the filler phrase can be actively maintained in working memory ("maintenance account"), or it can be retrieved only when the parser posits a gap ("retrieval account"). The current study tested whether filler content is maintained during the processing of dependencies. Using a self-paced reading paradigm, we compared reading times on a noun phrase (NP) between the filler and gap sites in object relative clauses, to reading times on an NP between the antecedent and ellipsis sites in ellipsis sentences...

The descending corticospinal (CS) projection has been considered a key element for motor control, which results from direct and indirect modulation of spinal cord pre-motor interneurons in the intermediate gray matter of the spinal cord, which, in turn, influences motoneurons in the ventral horn. The CS tract (CST) is also involved in a selective and complex modulation of sensory information in the dorsal horn. However, little is known about the spinal network engaged by the CST and the organization of CS projections that may encode different cortical outputs to the spinal cord...

BACKGROUND: Trabeculotomy with the Trabectome® is an effective surgical procedure to lower intraocular pressure (IOP). However, in some patients it does not lead to a significant IOP reduction despite a gonioscopically well visible opening of Schlemm's canal. This study investigated whether the size of the trabeculotomy opening and other parameters, including anterior chamber depth (ACD) are related to IOP reduction. METHODS: Retrospective observational case series with 93 eyes of 93 patients who underwent Trabectome surgery...

Thermal paper contains potentially toxic compounds such as bisphenol A (BPA), which is used as a color developer. BPA has been reported in thermal paper in concentrations up to 42,600 μg g(-1). The exposure to BPA via dermal transfer has been recently discussed as a significant contribution to the overall human exposure and the estimated daily intake (EDI) has been reported up to 218 μg d(-1). BPA has been also detected in recycled paper with concentrations up to 46 μg g(-1). Due to the fact that BPA is a known endocrine disruptor and migrates from materials, regulatory restrictions have been established to prevent risks for the human health...

Kinetic and thermodynamic compensations have been reported in many chemical, physical, biological and food processes. Kinetic compensation can be found for any process and when it takes place, it gives information about the reaction mechanism and whether the reaction is controlled by enthalpy or entropy. It consists of the linear relationship between the logarithm of the frequency factor (lnk0) and the activation energy (Ea), both previously obtained from the Arrhenius equation for different values of an environmental variable (e...

In recent years, interesterified fat (IF) has been used to replace hydrogenated vegetable fat (HVF), rich in trans isomers, being found in processed foods. Studies involving IF have shown deleterious influences on the metabolic system, similarly to HVF, whereas no studies regarding its influence on the central nervous system (CNS) were performed. Rats from first generation born and maintained under supplementation (3g/Kg, p.o.) of soybean-oil or IF until adulthood were assessed on memory, biochemical and molecular markers in the hippocampus...

REVIEW
Micol E Fiori, Lidia Villanova, Ruggero De Maria
Cancer stem cells (CSCs) represent the main target of the current efforts to eradicate cancer, because of their ability to promote metastatic dissemination and survive cytotoxic therapies. Here, we highlight the potential of patient-derived CSCs as an in vitro and in vivo pre-clinical model and of liquid biopsy as a diagnostic, prognostic and predictive tool. We discuss recently developed therapeutic strategies aiming at specifically targeting the cancer stem cell population, particularly focusing on the latest advances in cancer immunotherapy...

This work is an evaluation of metal contamination degree in Phorcus turbinatus and a monitoring of metals impact on metallothioneins functioning. The gastropod was sampled from six stations along the northeastern and eastern coasts of Tunisia during four seasons (2014-2015). Our results suggested that sedimentological metallic contents (Copper, Zinc and Cadmium) vary significantly depending on stations and not significantly according to seasons except for copper. Nevertheless, differences were no significant between stations and significant between seasons as for ambient factors, metallic intrinsic contents and metallothioneins rates...

PURPOSE: Long-term survival of women with advanced-stage ovarian cancer is relatively rare. Little is known about quality of life (QOL) and survivorship concerns of these women. Here, we describe QOL of women with advanced-stage ovarian cancer surviving for 8.5 years or longer and compare women with 0-1 recurrence to those with multiple recurrences. METHODS: Participants (n=56) recruited from 5 academic medical centers and the Ovarian Cancer Research Fund Alliance completed surveys regarding QOL (FACT-O), mood (CESD), social support (SPS), physical activity (IPAQ-SF), diet, and clinical characteristics...

INTRODUCTION: Physical activity has been shown to significantly improve health-related quality of life (HRQOL) and survivorship in a variety of patients with cancer . However, little is known about the physical activity patterns of bladder cancer survivors and how these are related to HRQOL in the United States. Our objective was to describe self-reported physical activity patterns and HRQOL and examine the association between these measures in a large cohort of bladder cancer survivors...

The eye is a complex structure composed of several interconnected tissues acting together, across the whole globe, to resist deformation due to intraocular pressure (IOP). However, most work in the ocular biomechanics field only examines the response to IOP over smaller regions of the eye. We used high-field MRI to measure IOP induced ocular displacements and deformations over the whole globe. Seven sheep eyes were obtained from a local abattoir and imaged within 48 h using MRI at multiple levels of IOP. IOP was controlled with a gravity perfusion system and a cannula inserted into the anterior chamber...

OBJECTIVES: This study compared whispering attempts by adults using tracheoesophageal (TE) speech with those by adults with a larynx. Comparisons were based on listener judgments, visual-perceptual assessment of spectrograms, and measures of the acoustic signal. STUDY DESIGN: This was a prospective, cross-sectional study. METHODS: Seventeen TE and 10 laryngeal speakers produced sentences in a whisper and in their spoken voice. Listeners judged sentences as whispered or spoken...

Radioresistant bacteria (RRB) are among the most radioresistant organisms and has a unique role in evolution. Along with the evolutionary role, radioresistant organisms play important role in paper industries, bioremediation, vaccine development and possibility in anti-aging and anti-cancer treatment. The study of radiation resistance in RRB was mainly focused on cytosolic mechanisms such as DNA repair mechanism, cell cleansing activity and high antioxidant activity. Although it was known that protein localized on outer areas of cell play role in resistance towards extreme condition but the mechanisms/proteins localized on the outer area of cells are not studied for radioresistance...

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a hypersensitivity reaction associated with a variety of drugs, mainly anticonvulsants, which is characterized by systemic symptoms and erythematous lesions, common to other toxicodermas. It is an uncommon clinical entity that requires a high suspicion by clinical staff given its varied initial presentation, and the fact that symptoms can overlap with those of other adverse cutaneous reactions to drugs. Without early diagnosis and appropriate treatment, mortality increases...

Altered protein phosphorylation states of several proteins are closely associated with Alzheimer's disease (AD). Among these are the amyloid-β precursor protein (AβPP) and the tau protein. In fact, altered protein phosphorylation states already provide strong biomarkers for AD diagnosis, as is the case with hyperphosphorylated tau. It follows that modulating signaling cascades provides an attractive avenue for exploring novel therapeutic strategies. This review focuses on some of the major protein kinases and protein phosphatases relevant to AD...

A vascular access (VA) is used to facilitate hemodialysis in patients that suffer from end-stage renal disease. However, they suffer from high failure rates due to non-maturation and venous stenosis, with intimal hyperplasia (IH) the underlying cause of both conditions. Abnormal hemodynamic profiles, which arise following VA creation, are believed to lead to the development of IH. However, the exact physiological response that initiates this process is unknown. This review evaluates the different hemodynamic parameters that are hypothesised to correlate with the development of IH...

We introduce multilevel multivariate meta-analysis methodology designed to account for the complexity of contemporary psychological research data. Our methodology directly models the observations from a set of studies in a manner that accounts for the variation and covariation induced by the facts that observations differ in their dependent measures and moderators and are nested within, for example, papers, studies, groups of subjects, and study conditions. Our methodology is motivated by data from papers and studies of the choice overload hypothesis...

Since the nineteenth century several clinical features have been observed in common between migraine and epilepsy (such as episodic attacks, triggering factors, presence of aura, frequent familiarity), but only in recent years researchers have really engaged in finding a common pathogenic mechanism. From studies of disease incidence, we understand how either migraine among patients with epilepsy or epilepsy among migraine patients are more frequent than in the general population. This association may result from a direct causality, by the same environmental risk factors and/or by a common genetic susceptibility...

Arne May
Due to the clinical picture and also based on early imaging data (Weiller et al. Nat Med 1:658-660, 1995), the brainstem and midbrain structures have been intensely discussed as possible driving or generating structures in migraine. The fact that the brainstem activation persisted after treatment makes it unlikely that this activation was only due to increased activity of the endogenous anti-nociceptive system. It was consequently (and somewhat simplifying) coined the "migraine generator". Since then several studies have focussed on this region when investigating episodic, but also chronic migraine...

Christopher J Webster, Gillian R Woollett
Major drug regulators have indicated in guidance their flexibility to accept some development data for biosimilars generated with reference product versions licensed outside their own jurisdictions, but most authorities require new bridging studies between these versions and the versions of them licensed locally. The costs of these studies are not trivial in absolute terms and, due to the multiplier effect of required repetition by each biosimilar sponsor, their collective costs are substantial. Yet versions of biologics licensed in different jurisdictions usually share the same development data, and any manufacturing changes between versions have been justified by a rigorous comparability process...
