Abstract:

Breakfast skipping and nighttime snacking have been identified as risk factors for obesity, diabetes, and cardiovascular diseases. However, the effects of irregularity of meal timing on health and daily quality of life are still unclear. In this study, a web-based self-administered questionnaire survey was conducted involving 4490 workers (73.3% males; average age = 47.4 ± 0.1 years) in Japan to investigate the association between meal habits, health, and social relationships. This study identified that irregular meal timing was correlated with higher neuroticism (one of the Big Five personali

Abstract:

Abstract Introduction Misalignment between the central circadian clock and daily behaviors increases cardiometabolic morbidity and mortality risk, likely due to internal misalignment between central and peripheral circadian rhythms. Experimental studies suggest food intake may act as a time cue (‘zeitgeber’) for resetting circadian rhythms, representing a potential behavioral target to ameliorate circadian misalignment and associated health consequences. However, the extent to which eating timing relates to circadian rhythms in free-living adults is unclear. Therefore, we tested the associatio

BACKGROUND: At the present time all worldwide diesel engine manufacturers have directed their development strategies on the way of reduction of harmful emissions, fuel efficiency improving and increasing of the power per liter. Using only accumulator type system is not sufficient for the goals achievement. It is necessary to use new auxiliary units, such as an exhaust catalyst, an exhaust recirculation system, injection of additional liquids together with diesel fuel, as well as to improve the existing units.

There is considerable debate over whether the brain codes information using neural firing rate or the fine-grained structure of spike timing.

The task required flexion to four different displacements against two opposing torques; the eight possible conditions were randomly interleaved.

ABSTRACT Growing evidence suggests that personality traits play a role in obesity and cardiometabolic health. In addition, irregularity of food intake has emerged as a potential risk factor for obesity, cardiovascular disease, and metabolic syndrome. Recent studies suggest that when we eat, termed “chrono-nutrition,” may be as important to what we eat. This concept covers 3 aspects: 1) irregularity of energy intake in meals (varying amounts of energy intake throughout the day and at different times from one day to the next), 2) frequency (number of meals per day), and 3) timing of food intake

Self-report questionnaire measuring chronotype, trait self-control, sleep hygiene behaviors, bedtime media use and sleep quality was administered to 224 Chinese adult participants (83.5% female). A multiple mediation model was estimated with sleep hygiene habits and bedtime media use as parallel mediators of the relations between chronotype, trait self

Abstract:

The present day at engineering plants occurs the following problem: an inadequacy of management decisions made to the required state of manufacturing causing high production costs, higher length of the production cycle and irregularity in timing of orders. To solve this problem the author of this work has developed a methodology for the management of differ-ent and dynamic production based on a system approach. The main way for the realization of the system approach lies through the formation of an adequate integrated information system of an engineering plant control. With the aid of the inte

Abstract:

Background: Emergency contraception (EC) is a safe and cost effective measure, which when used judiciously can avoid unintended pregnancies. This is especially relevant in our country where both population control and unsafe abortions are a serious concern. For any contraceptive to be effective, the general population must have a proper knowledge and a positive attitude towards it. Women who come for medical termination of unwanted pregnancy are the best representatives of this and our study aimed to assess the knowledge and awareness of EC in this group.Methods: It was a descriptive, cross-se

We further characterized these crypt changes (CC), their timing of occurrence, and tested their association with infection/inflammatory conditions. Methods Hematoxylin and eosin-stained slides of 345 VA were evaluated for the presence or absence of CC and their different morphologies. Autopsy reports were reviewed for evidence of amniotic fluid or fetal systemic infection and placental inflammatory conditions. Results Crypt dilatation with or without irre

Abstract:

In this paper we have calculated the duration of cycles manifested in the prices of second-hand tanker ships, using the method of Rescale Range (R/S) Analysis. We have considered a time series of 312 monthly data, taken between the years 1976–2001, and combined R/S with a study of its V-statistic, Power Spectrum Analysis and Sharpe Ratio. Our ultimate goal is to be able to help decision-makers use this analysis in order to buy or sell a ship at the "best timing". As the sale and purchase ship market exhibits a strongly deterministic cyclical behavior with a high degree of "irregularity" (or "v

Using a multidimensional sleep health framework, we examined the association of individual sleep health dimensions and a composite sleep health score with hemoglobin A1c (HbA1c) and depressive symptoms among African American adults with type 2 diabetes. Methods Participants (N = 257; mean age = 62.5 years) were recruited through local churches. Wrist-worn actigraphy and sleep questionnaire data assessed multidimensional sleep health using the RuSATED framework (regularity, satisfaction, alertness, timing, efficiency, duration).

Abstract:

Atrial fibrillation (AF), the most common cardiac arrhythmia, is associated with adverse CV outcomes. Vascular aging (VA), which is defined as the progressive deterioration of arterial function and structure over a lifetime, is an independent predictor of both AF development and CV events. A timing identification and treatment of early VA has therefore the potential to reduce the risk of AF incidence and related CV events.

Abstract:

Placenta-derived hormones including growth hormone (GH) in humans contribute to maternal adaptation to pregnancy, and intermittent maternal GH administration increases foetal growth in several species. Both patterns and abundance of circulating GH are important for its activity, but their changes during pregnancy have only been reported in humans and rats. The aim of the present study was to characterise circulating profiles and secretory characteristics of GH in non-pregnant female mice and throughout murine pregnancy. Circulating GH concentrations were measured in whole blood (2 μL) collecte

Abstract:

Abstract As a conveyor belt transferring inland ice to ocean, ice shelves shed mass through large, systematic tabular calving, which also plays a major role in the fluctuation of the buttressing forces. Tabular iceberg calving involves two stages: first is systematic cracking, which develops after the forward-slanting front reaches a limiting extension length determined by gravity–buoyancy imbalance; second is fatigue separation. The latter has greater variability, producing calving irregularity. Whereas ice flow vertical shear determines the timing of the systematic cracking, wave actions are

Adaptation strategies like irrigation or fertilization can help to cope with the negative impacts of climate uncertainty. This study evaluated the effects of water regime and nitrogen (N) fertiliza
