The light regime is an ecologically important factor in pelagic habitats, influencing a range of biological processes. However, the availability and importance of light to these processes in high Arctic zooplankton communities during periods of 'complete' darkness (polar night) are poorly studied. Here we characterized the ambient light regime throughout the diel cycle during the high Arctic po...

Understanding the geographic and temporal spread of food-borne diseases associated with fresh produce is crucial for informing adequate surveillance and control. As a first step towards this goal, we develop and analyze a novel three stage model at the processing/sanitization juncture in the fresh produce supply chain. The key feature of our model is its ability to describe the dynamics of cros...

OBJECTIVE AND METHOD Aggregating across retrospective cohort samples, this integrative review synthesizes the findings of 12 cumulative incidence studies (45 hypotheses) on anorexia nervosa secular trends. RESULTS (1) The female/male anorexia incidence rate ratio was estimated to be 8.20, 18.46 versus 2.25 cases per 100,000 per year, p < .05; (2) female teenagers experienced anorexia at a rat...

OBJECTIVE Contemporary childbearing is associated with greater gestational weight gain and postpartum weight retention than in previous decades, potentially leading to a more pronounced effect of childbearing on women's long-term obesity risk. Previous work on the association of childbearing with women's long-term obesity risk mostly examined births in the 1970s and 1980s and produced mixed res...

This case report describes endodontic therapy on a mandibular first molar with unusual root morphology. In the initial treatment the working length had been determined with only an apex locator; no periapical radiographs had been obtained because the patient was pregnant. The root canal into an additional distolingual root had not been found and was therefore left untreated, which led to treatm...

Objective: the objective of the study was to determine the relationship between dental calcification stages and skeletal maturation in a Peruvian sample. Methods: panoramic, cephalometric and carpal radiographs of 78 patients (34 girls and 44 boys) between 7 and 17 years old (9.90 ± 2.5 years) were evaluated. Stages of tooth calcification of the mandibular canine, first premolar, second prem...

BACKGROUND Fractures of the mandibular angle are common and comprise 31% of all mandibular fractures. Multiple recent studies report a 2-3 fold increased risk for mandibular angle fractures when un-erupted mandibular third molars are present. The objective of this study was to assess the frequency of un-erupted mandibular third molar in mandibular angle fractures. METHODS This cross-sectional...

I discovered a phenomenon related to nonverbal sex differences in young Japanese couples in which the female tends to assume the left side position and the male tends to assume the right position (FM tendency) when the couple are walking on sidewalks and in parks. As the first step of the present study, some aspects of this phenomenon were examined through field observation. In total, 2,827 cou...

The aim of this study was to assess the effect of varying the maximum resting period between consecutive ambulatory bouts in community-based outcomes. Ambulation was assessed in 97 community-dwelling older adults (mean (SD) age 69.2 (7.7) years) using an accelerometer (activPAL™) worn on the upper thigh for 7 consecutive days. The volume, pattern and variability of ambulation were calculated ov...

We report the largest experience, to our knowledge, of home cardiorespiratory monitoring in 47,495 newborns using the novel Owlet Smart Sock (OSS) technology (October 2015 to May 2017). On average, 47,495 newborns were monitored for 6 months, 4.5 d/wk, 9.9 h/d. Continuous readings of oxygen saturation and heart rate were obtained from 39,626 full-term newborns. OSS users were likely first-time ...
