We aimed to examine smoking-related content in all 24 James Bond movies in the Eon Productions series from 1962 to 2015. There were favourable downward trends for any smoking by James Bond (p=0.015 for trend), and for tobacco-related spy-gadgetry (p=0.009). Around 20% of Bond's 60 sexual partners smoked in each decade, and most recently in 2012. There were regular mentions of smoking risks to health (starting from 1967) and product placement of branded packs was present in two movies. Overall, the persisting smoking content remains problematic from a public health perspective, especially given the popularity of this movie series...

Schizophrenic (SCZ) and autism (ASD) spectrum disorders share several features including social cognition impairments. In SCZ, the link between symptomatic dimensions and social cognition deficits remains unclear. The Movie for the Assessment of Social Cognition (MASC) test, available in several languages including English, investigates mental state attribution capabilities in complex interpersonal situations. After its translation into French, we used MASC to direct compare social cognition in 36 young participants with SCZ to 19 with ASD and 20 healthy controls (HC) matched for gender, age (18-25y...

This paper features two studies confirming a lasting impact of first learning on how subsequent experience is weighted in early relevance-filtering processes. In both studies participants were exposed to sequences of sound that contained a regular pattern on two different timescales. Regular patterning in sound is readily detected by the auditory system and used to form "prediction models" that define the most likely properties of sound to be encountered in a given context. The presence and strength of these prediction models is inferred from changes in automatically elicited components of auditory evoked potentials...

Testing infants in the laboratory is expensive in time and money; consequently, many studies are underpowered, reducing their reproducibility. We investigated whether the online platform, Amazon Mechanical Turk (MTurk), could be used as a resource to more easily recruit and measure the behavior of infant populations. Using a looking time paradigm, with users' webcams we recorded how long infants aged 5 to 8months attended while viewing children's television programs. We found that infants (N=57) were more reliably engaged by some movies than by others and that the most engaging movies could maintain attention for approximately 70% of a 10- to 13-min period...

Hemodynamic-based brain imaging techniques are typically incapable of monitoring brain activity with both high spatial and high temporal resolutions. In this study, we have used intrinsic signal optical imaging (ISOI), a relatively high spatial resolution imaging technique, to examine the temporal resolution of the hemodynamic signal. We imaged V1 responses in anesthetized monkey to a moving light spot. Movies of cortical responses clearly revealed a focus of hemodynamic response traveling across the cortical surface...

Due to its availability, low cost, flat geometry, and transparency, the ex ovo chick embryo has become a major vertebrate animal model for the study of morphogenetic events, such as gastrulation(2), neurulation(3)(-)(5), somitogenesis(6), heart bending(7,8), and brain formation(9)(-)(13), during early embryogenesis. Key to understanding morphogenetic processes is to follow them dynamically by time-lapse imaging. The acquisition of time-lapse movies of chick embryogenesis ex ovo has been limited either to short time windows or to the need for an incubator to control temperature and humidity around the embryo(14)...

PURPOSE: To develop a practical method for routine QA of the MLC of a Tomotherapy unit using ArcCheck. METHODS: Two standard test plans were used in this study. One was a helical test, in which the central leaves No. 32 and 33 opened simultaneously for 277.8ms at projections centered at 0°, 120° and 240° gantry angles. The other test plan was a static test with the gantry angle set at 0°, 45°, 90° and 135° respectively and leaves No. 32 and 33 opened sequentially for total 20s which was further divided into eleven or ten segments at each beam angle...

PURPOSE: To develop a methodology using an ArcCheck for accurate QA measurements of the gantry angle and speed of a Tomotherapy unit. METHODS: Two test plans recommended by TG148 were chosen for this study. One was the helical star shot test which had a total of 40 gantry rotations while the couch moved continuously and the multi-leaves opened for projections centered at 0°, 120° and 240°. The plan set a gantry start angle of -2.5° to ensure the projections were centered at the expected angles...

PURPOSE: To develop a filmless methodology based on an ArcCheck for QA measurement of the couch translation per gantry rotation and couch speed of a Tomotherapy unit. METHODS: Two test plans recommended by TG148 were chosen for this study. A helical plan with 1 cm field size opened the leaves for 180 degrees at the 2nd, 7th and 12th of total 13 rotations and was used to verify if the couch travelled the expected distance per gantry rotation. The other test plan was a static plan with the gantry at 0°, 1cm field width and constant couch movement speed of 0...

PURPOSE: To develop a novel strategy to extract the respiratory motion of the thoracic diaphragm from kilovoltage cone beam computed tomography (CBCT) projections by a constrained linear regression optimization technique. METHODS: A parabolic function was identified as the geometric model and was employed to fit the shape of the diaphragm on the CBCT projections. The search was initialized by five manually placed seeds on a pre-selected projection image. Temporal redundancies, the enabling phenomenology in video compression and encoding techniques, inherent in the dynamic properties of the diaphragm motion together with the geometrical shape of the diaphragm boundary and the associated algebraic constraint that significantly reduced the searching space of viable parabolic parameters was integrated, which can be effectively optimized by a constrained linear regression approach on the subsequent projections...

PURPOSE: Tomotherapy delivers an intensity-modulated radiation therapy (IMRT) treatment by the synchronization of gantry rotation, multileaf collimator (MLC), and couch movement. This dynamic nature makes the quality assurance (QA) important and challenging. The purpose of this study is to develop some methodologies using an ArcCHECK for accurate QA measurements of the gantry angle and speed, MLC synchronization and leaf open time, couch translation per gantry rotation, couch speed and uniformity, and constancy of longitudinal beam profile for a Tomotherapy unit...

Changes in room acoustics provide important clues about the environment of sound source-perceiver systems, for example, by indicating changes in the reflecting characteristics of surrounding objects. To study the detection of auditory irregularities brought about by a change in room acoustics, a passive oddball protocol with participants watching a movie was applied in this study. Acoustic stimuli were presented via headphones. Standards and deviants were created by modelling rooms of different sizes, keeping the values of the basic acoustic dimensions (e...

Long-term studies of Caenorhabditis elegans larval development traditionally require tedious manual observations because larvae must move to develop, and existing immobilization techniques either perturb development or are unsuited for young larvae. Here, we present a simple microfluidic device to simultaneously follow development of ten C. elegans larvae at high spatiotemporal resolution from hatching to adulthood (∼3 days). Animals grown in microchambers are periodically immobilized by compression to allow high-quality imaging of even weak fluorescence signals...

OBJECTIVES: We proposed a new virtual bronchoscopy tool to improve the accuracy of traditional transbronchial needle aspiration for mediastinal staging. METHODS: Chest-computed tomographic images (1 mm thickness) were reconstructed with Osirix software to produce a virtual bronchoscopic simulation. The target adenopathy was identified by measuring its distance from the carina on multiplanar reconstruction images. The static images were uploaded in iMovie Software, which produced a virtual bronchoscopic movie from the images; the movie was then transferred to a tablet computer to provide real-time guidance during a biopsy...

Cryo-electron microscopy recently experienced great improvements in structure resolution due to direct electron detectors with improved contrast and fast read-out leading to single electron counting. High frames rates enabled dose fractionation, where a long exposure is broken into a movie, permitting specimen drift to be registered and corrected. The typical approach for image registration, with high shot noise and low contrast, is multi-reference (MR) cross-correlation. Here we present the software package Zorro, which provides robust drift correction for dose fractionation by use of an intensity-normalized cross-correlation and logistic noise model to weight each cross-correlation in the MR model and filter each cross-correlation optimally...

OBJECTIVE: To assess whether exposure to movie smoking is associated with cigarette smoking among Argentinian adolescents. STUDY DESIGN: A school-based longitudinal study involving 33 secondary schools in Argentina was performed. The sample included 2502 never smokers (average age at entry = 12.5 years), 1700 (67.9%) of whom completed follow-up surveys 17 months later. Exposure to the top 100 highest-grossing films for each year between 2009 and 2013 was assessed by content-coding films for tobacco and then by asking adolescents whether they had seen each of 50 titles, randomly selected from the larger pool, then parsing exposure into tertiles...

BACKGROUND: This study examined whether acutely (aMDD) and remitted depressed patients (rMDD) show deficits in the two aspects of social cognition - facial emotion recognition (FER) and reasoning - when using ecologically valid material. Furthermore, we examined whether reduced facial mimicry mediates the association between depressive symptoms and FER, and whether FER deficits and reasoning deficits are associated. METHOD: In 42 aMDD, 43 rMDD, and 39 healthy controls (HC) FER was assessed using stimuli from the Amsterdam Dynamic Facial Expression Set, reasoning by the Movie for the Assessment of Social Cognition...

: Non-human primate neuroanatomical studies have identified a cortical pathway from the superior temporal sulcus (STS) projecting into dorsal sub-regions of the amygdala, but whether this same pathway exists in humans is unknown. Here, we addressed this question by combining thetaburst transcranial magnetic stimulation (TBS) with functional magnetic resonance imaging (fMRI) to test the prediction that the STS and amygdala are functionally connected during face perception. Human participants (N=17) were scanned, over two sessions, while viewing 3-second video clips of moving faces, bodies and objects...
