Despite the literatures on the role of input in adult second language (L2) acquisition, and on artificial and statistical language learning, surprisingly little is known about how adults break into a new language in the wild. This paper reports on a series of behavioral and neuroimaging studies that examine what linguistic information adults can extract from naturalistic but controlled audio-visua
The mucosal immune system identifies and fights invading pathogens, while allowing non-pathogenic organisms to persist. Mechanisms of pathogen/non-pathogen discrimination are poorly understood, as is the contribution of human genetic variation in disease susceptibility. We describe here a new, IRF3-dependent signaling pathway that is critical for distinguishing pathogens from normal flora at the m
THE aim of this study was to explore whether brain-derived neurotrophic factor (BDNF) can improve neuronal survival in cell cultures of rat dentate gyrus subjected to a hypoglycaemic insult. Glucose deprivation for 15 h caused severe neuronal loss (about 70%). BDNF added either 24 h before or 4 h after onset of hypoglycaemia completely protected granule cells against this insult-induced damage. Ne
Complement evasion by various mechanisms is important for microbial virulence and survival in the host. One strategy used by some pathogenic bacteria is to bind the complement inhibitor of the classical pathway, C4b-binding protein (C4BP). In this study, we have identified a novel interaction between nontypeable Haemophilus influenzae (NTHi) and C4BP, whereas the majority of the typeable H. influe
The purpose of this work is to investigate the interaction between transport processes and chemical reactions, with special emphasis on modeling mass transport by the Lattice Boltzmann method (LBM) at microscale of the anode of a solid oxide fuel cell (SOFC). In order to improve the performance of an SOFC, it is important to determine the microstructural effect embedded within the physical and che
BACKGROUND: Matrilysin (MMP-7) elevation after radiotherapy is shown in humans. Matrilysin regulates certain cytokines and the production of bactericidal proteins when the mucosa is exposed to bacterial antigens. We investigate the effect of irradiation on matrilysin and microflora in murine bowel, after modulation with antibiotics. METHODS: Animals were divided into two different groups a radiati
This paper adopts a high-speed TSPC frequency and phase detector,a typical charge pump,and cross-coupled differential delay cells to realized a good frequency synthesizer applied to 1000Base-T Ethernet transceiver as well as 10/100Mbps modes.This frequency synthesizer can not only meet the requirements of the transmitter for very precise rising (falling) edge time control but also offer much finer
Cholesterol-rich clusters of SNARE (soluble NSF attachment protein receptor) proteins have been implicated as being important for exocytosis. Here we demonstrate the significance of cholesterol for normal biphasic insulin secretion in mouse beta cells by removal of cholesterol from the plasma membrane using methyl-beta-cyclodextrin (MBCD). Maximal inhibition of insulin secretion in static incubati
OBJECTIVES: Peripheral vascular disease (PVD) is an important limiting factor for healing in neuroischemic or ischemic diabetic foot ulcer. The purpose of this study was to identify factors related to healing in patients with diabetes with foot ulcers and severe PVD. METHODS: Patients with diabetes with a foot ulcer, consecutively presenting at a multidisciplinary foot center with a systolic toe p
A level crossing predictor is a predictor process $Y(t)$, possibly multivariate, which can be used to predict whether a specified process $X(t)$ will cross a predetermined level or not. A natural criterion on how good a predictor is, can be the probability that a crossing is detected a sufficient time ahead, and the number of times the predictor makes a false alarm. If $X$ is Gaussian and the proc
Short-term outcome and side effects after Uvulopalatopharyngoplasty (UPPP) are well recognized. However, there is a lack of knowledge of the long-term outcome and side effects after this surgery. This study was completed to investigate the outcome and side effects 20 years after UPPP for snoring and obstructive sleep apnoea.
There is a great deal of justified concern about continuity through scientific theory change. Our thesis is that, particularly in physics, such continuity can be appropriately captured at the level of conceptual frameworks (the level above the theories themselves) using conceptual space models. Indeed, we contend that the conceptual spaces of three of our most important physical theories---Classic
Methane is the second most important long-lived greenhouse gas and plays a central role in the chemistry of the Earth's atmosphere. Nonetheless there are significant uncertainties in its source budget. Analysis of the isotopic composition of atmospheric methane, including the doubly substituted species 13CH3D, offers new insight into the methane budget as the sources and sinks have distinct isotop
Hypothermia can reduce neuronal death caused by ischemia and traumatic brain injury. We therefore investigated whether mild hypothermia in rats receiving a transplant of embryonic mesencephalic rat tissue increases survival of the implanted dopaminergic neurons. Mild hypothermia (32-33°C) during graft implantation and for the following 90 min significantly increased the survival of transplanted do
Background Subgaleal masses are relatively common in the clinical praxis, and after a trauma to the head, a subgaleal hematoma is usually suspected. However, other differential diagnoses, such as malignant tumors, should be kept in mind despite a history of a previous trauma. Case description and Conclusions We report a case of a subgaleal mass that was clinically and radiologically diagnosed as a
The traditional pre-post treatment difference reflects an incremental notion of change, where a quantity of some psychological function is added to (or subtracted from) a pretreatment quantity. This study presents a complementary, experiential notion of change. Rather than a difference, change is a feeling or experience of having changed, a feeling that one is different than before. Based on a pos
Protein engineering to functionalize the self-assembling enamel matrix protein amelogenin with a cellulose binding domain (CBD) is used. The purpose is to examine the binding of the engineered protein, rh174CBD, to cellulose materials, and the possibility to immobilize self-assembled amelogenin nanospheres on cellulose. rh174CBD assembled to nanospheres ≈35 nm in hydrodynamic diameter, very simila
