Not letter

Complex words in Hebrew are composed of two non-concatenated morphemes: a consonantal root embedded in a nominal or verbal word-pattern morpho-phonological unit made up of vowels or vowels and consonants. The root carries the core meaning of the word, whereas the word-pattern creates variations on this meaning, determines the word's grammatical characteristics, and carries segmental and suprasegmental information about the word's structure. Research on written-word recognition has revealed a robust effect of the roots and the verbal-patterns, but not of the nominal-patterns, on word recognition...

Despite the general advances in dental care, dental caries is still a global health problem affecting many children. Occlusal surfaces of first permanent molars are the most susceptible sites in the developing permanent dentition. Dentists should use sealants or fluoride varnish - as well as other means - to limit the onset of tooth decay. Application of sealants is a recommended procedure to prevent or control caries. Sealing occlusal surfaces of newly erupted permanent molars in children and teenagers delays caries onset up to 48 months compared with unsealed teeth...

The aim with any review is to summarize an expert's assessment of the literature where readers benefit from the reviewers overview and evaluation of the validity and applicability of individual studies. Millet and co-workers are of the opinion that our review (Lundby and Robach, 2016) is selective and that their studies are not fully and accurately represented in it. The reason for not including some of their studies is that we believe them to be flawed and we disagree that the studies we do cite are misinterpreted...

PURPOSE: The association of retrievable inferior vena cava filters (IVCFs) with adverse events has led to increased interest in prompt retrieval, particularly in younger patients given the progressive nature of these complications over time. This study takes a design-of-experiments (DOE) approach to investigate methods to best improve filter retrieval rates, with a particular focus on younger (<60 years) patients. METHODS: A DOE approach was executed in which combinations of variables were tested to best improve retrieval rates...

In the partial-report task, subjects are asked to report only a portion of the items presented. Selective attention chooses which objects to represent in short-term memory (STM) on the basis of their relevance. Because STM is limited in capacity, one must sometimes choose which objects are removed from memory in light of new relevant information. We tested the hypothesis that the choices among newly presented information and old information in STM involve the same process-that both are acts of selective attention...

BACKGROUND: Because tissue transplantation (TTx) has not been familiar to the general public or even to medical staffs in Japan, awareness of TTx is very important to increase tissue donation. Our primary aim was to describe the current status of awareness of TTx in medical staffs and in the general public around Osaka. METHODS: Between July 2014 and February 2015, 1015 general public citizens, 203 medical staff members working in emergency hospitals, and 168 cardiothoracic surgeons were invited to complete a letter or web-based survey through the use of a self-designed questionnaire...

BACKGROUND: Bowel preparation is inadequate in a large proportion of colonoscopies, leading to multiple clinical and economic harms. While most patients receive some form of education before colonoscopy, there is no consensus on the best approach. AIMS: This systematic review aimed to evaluate the efficacy of patient education interventions to improve bowel preparation. METHODS: We searched the Cochrane Database, CINAHL, EMBASE, Ovid, and Web of Science...

Bit commitment is a fundamental cryptographic primitive in which a party wishes to commit a secret bit to another party. Perfect security between mistrustful parties is unfortunately impossible to achieve through the asynchronous exchange of classical and quantum messages. Perfect security can nonetheless be achieved if each party splits into two agents exchanging classical information at times and locations satisfying strict relativistic constraints. A relativistic multiround protocol to achieve this was previously proposed and used to implement a 2-millisecond commitment time...

Bidimensional NMR analysis may be a useful tool to resolve the structure of chemical compounds also in mixture. This letter would demonstrate how these techniques could be applied e.g. to the reported case on identification of benzophenone glycoside from Psidium guajava. A tentative structure for the secondary component, not yet described, was possibly proposed on the basis of observation and critic review of available 1D and 2D NMR spectra.

Increasing evidence has shown visual attention span to be a factor, distinct from phonological skills, that explains single-word identification (pseudo-word/word reading) performance in dyslexia. Yet, little is known about how well visual attention span explains text comprehension. Observing reading comprehension in a sample of 105 high school students with dyslexia, we used a pathway analysis to examine the direct and indirect path between visual attention span and reading comprehension while controlling for other factors such as phonological awareness, letter identification, short-term memory, IQ and age...

PURPOSE: The United States Medical Licensing Examination (USMLE) Step 1 plays a pivotal role in one's residency application. While prior literature has investigated which factors influence performance on the examination, the authors sought to include factors such as performance on a well-used question bank and financial need to develop a predictive model. METHOD : After obtaining institutional review board approval, the authors surveyed two consecutive second-year medical school classes and correlated the data to the students' Step 1 and National Board of Medical Examiners (NBME) Comprehensive Basic Science Examination (CBSE) scores...

Word reading partly depends on the activation of sublexical letter clusters. Previous research has studied which types of letters clusters have psychological saliency, but less is known about cognitive mechanisms of letter string parsing. Here, we take advantage of the high degree of context-dependency of the Russian orthography to examine whether CV clusters are treated as units in two stages of sublexical processing. In two experiments using a nonword reading task, we use two orthogonal manipulations: (1) insertion of a visual disruptor (#) to assess whether CV clusters are kept intact during the early visual parsing stage, and (2) presence of context-dependent GPCs (e...

OBJECTIVE: To investigate the effect of an intervention in which medical-microbiological laboratories alert general practitioners (GPs) in writing about patients with a chronic hepatitis B or C infection in their practice, urging them to bring these patients under medical surveillance again now that treatment options have improved and guidelines have been revised. DESIGN: Descriptive, prospective. METHOD: All patients who had been diagnosed with hepatitis B or C between 2003 and 2013 on the request of the GP, and for whom diagnostics by an internist, infectious diseases specialist or gastrointestinal/liver specialist had never been requested, were included...

Hydrocephalus is a condition characterised by enlarged cerebral ventricles, which in turn affects intracranial pressure (ICP); however, the mechanisms regulating ICP are not fully understood. A nonlinear signal processing approach was applied to ICP signals measured during infusion studies from patients with two forms of hydrocephalus, in a bid to compare the differences. This is the first study of its kind. The two forms of hydrocephalus were idiopathic normal pressure hydrocephalus (iNPH) and secondary normal pressure hydrocephalus (SH)...

This Letter introduces a feasibility study of a scanning system for applications in biomedical bone imaging operating in the microwave range 0.5-4 GHz. Mechanical uncertainties and data acquisition time are minimised by using a fully automated scanner that controls two antipodal Vivaldi antennas. Accurate antenna positioning and synchronisation with data acquisition enables a rigorous proof-of-concept for the microwave imaging procedure of a multi-layer phantom including skin, fat, muscle and bone tissues. The presence of a suitable coupling medium enables antenna miniaturisation and mitigates the impedance mismatch between antennas and phantom...

Studies suggest that a word-length effect of up to 160 ms/letter distinguishes hemianopic dyslexia from pure alexia. However, partial preservation of central vision is common in right hemianopia, but its effects on single-word reading are unknown. Eighteen healthy subjects read single words with a gaze-contingent right hemianopia simulation that varied the degree of central sparing. Mean reading onset time declined with small degrees of central sparing, but the word-length effect did not decrease until sparing exceeded 3...

This is a letter to a young friend who has become a paediatrician. It is a senior paediatrician, trying to transmit something useful, that writes it. The lives of those who care are made of many human relationships, a lot of reading, more different interpretations of these relationships and these readings. Each of us will build over the years their ethical model, their ability to discuss new problems and new cases with colleagues, their ability to critically analyse the scientific literature as well as the willingness to listen to patients and families...
