Statement of Need Recent catastrophic bus and train accidents in the Bronx, New York, have highlighted the importance of understanding the negative effects of circadian sleep-wake disruption in shift workers, especially those in positions of responsibility for public safety, including bus and train operators and healthcare workers. Scientific evidence exists that manipulations by employers and employees can reduce the risk of errors due to sleep deprivation, so long as there is an understanding of underlying chronobiologic principles and the corresponding therapeutic options that can reduce and improve circadian disruption.. Activity Goal This program is designed to present the current understanding of chronobiology and the effects upon health and disease and to highlight the importance of circadian disruption on shift workers performances and productivity. Appropriate interventions can be undertaken by employers and employees to mitigate the effects of circadian disruption by manipulating ...

Introduction: Shift work, characterized by irregular schedules resulting in sleep loss and misalignment of circadian rhythms, is associated with increased incidence of cardiovascular disease. We tested whether circadian misalignment has an adverse impact on cardiovascular function independently of sleep loss. Methods: 19 healthy adults were studied using a parallel group design comparing two inter

Sleep duration and disruption have a significant impact on human health, quality of life, and life expectancy. Among humans, it is clear that the biological need for sleep varies dramatically. Natural short sleepers have a lifelong tendency to sleep only 4-5 h per night and to awaken refreshed and energetic. Natural long sleepers biologically require 9-10 h/night to feel well rested. The reason for these physiological differences is unknown and the genetic basis has not been explored.. Although relatively little is known regarding the genetic basis of sleep, there is a wealth of information on the genetics of circadian clock function across species. Sleep and circadian function are distinct processes that interact in living organisms. Although these two systems can operate independently, recent studies indicate a more intimate relationship.. Over the last decade, genetic material has been collected from individuals and families with circadian rhythm disturbances including familial advanced sleep ...

WASHINGTON - According to a new survey issued by the Heart Rhythm Society, the majority of Americans are unaware of two serious and potentially life-threatening heart rhythm disorders, atrial fibrillation (AF) and sudden cardiac arrest (SCA). In fact, only one in three Americans have ever heard of AF or recognize the number of lives claimed each year from SCA. Throughout February, Heart Health Month, the Heart Rhythm Society spotlights the need for public education on heart rhythm disorders affecting millions of people, and the specialists best suited to treat them - electrophysiologists.. More than 250,000 deaths occur each year as a result of SCA, more than breast cancer, lung cancer or AIDs. Yet, according to the recent survey, more than 65 percent of Americans not only underestimate the seriousness of SCA, but also believe SCA is a type of heart attack. While this current data does show a 5 percent increase since the Societys 2008 SCA awareness survey, the lack of awareness remains high and ...

Circadian clocks are found in nearly all organisms, from bacteria to mammals, and ensure that behavioral and physiological processes occur at optimal times of day and in the correct temporal order. It is becoming increasingly clear that chronic circadian misalignment (CCM), such as occurs in shift workers or as a result of aberrant sleeping and eating schedules common to modern society, has profound metabolic and cognitive consequences, but the proximate mechanisms connecting CCM with reduced organismal health are unknown. Furthermore, it has been difficult to disentangle whether the health effects are directly induced by misalignment or are secondary to the alterations in sleep and activity levels that commonly occur with CCM. Here, we investigated the consequences of CCM in the powerful model system of the fruit fly, Drosophila melanogaster. We subjected flies to daily 4-h phase delays in the light-dark schedule and used the Drosophila Activity Monitoring (DAM) system to continuously track locomotor

Behavioural signs and symptoms in dementia are of central clinical significance. There are a number of standardised rating scales available for the assessment of motor phenomena in dementia. However, there is no objective method of assessing these symptoms. In addition, the reliability of these scales, especially when used by caregivers from within families, has been questioned. In order to overcome this flaw, we propose the use of an actometric device for assessing behaviour motor symptoms in dementia. In the first part of this dissertation we assessed the reliability and the concurrent validity of an actometric device against two behavioural scales. Results show satisfactory validity and good reliability of this method. In the second part of this dissertation, we reanalysed data from our validation study, investigating whether the pattern of circadian rhythm disturbances is different in patients suffering from Alzheimer disease and patients suffering from vascular dementia, controlling ...

pH variation in Thionin: The Two-Faced Solution Integrated-Science students Erin Smyers and Nicole Loughner from Homer-Center High School in Homer City, PA, worked with their science team leader, Mark Shopland, to investigate the pH changes in an oxidation-reduction reaction. The students chose to work with Thionin based on the demonstration Thionin - The Two-Faced Solution published by Flinn Scientific Inc. (Publication No. 0815.00). According to the Flinn Chem-Fax, Thionin is an organic compound that in the oxidized form is purple and in the reduced form is colorless. When a reducing agent such as iron(II) ion (Fe2+) is added to an acidic thionin solution, the thionin (Thio+) molecule accepts two hydrogen atoms and is reduced to its colorless form. This reaction only takes place in the presence of an intense light source. Thio+ + 2Fe2+ + 2H+ + Light ↔ ThioH2+ + 2Fe3+ [purple] [colorless] The graph shows the relatively constant pH under normal lighting conditions and the varying pH levels of the

Abstract:. BACKGROUND: Sleep-wake disturbances have frequently been reported in bipolar disorder and schizophrenia, and are considered to be caused by an underlying circadian rhythm disorder. The study presented here was designed to investigate the existence of Per3 polymorphism in bipolar disorder type I (BD-I) and schizophrenic patients in South India. METHODS: Blood samples were collected from 311 BD-I patients, 293 schizophrenia patients, and 346 age- and sex-matched normal controls. Per3 genotyping was performed on DNA by polymerase chain reaction using specific primers. RESULTS: An increased prevalence of five repeat homozygotes was seen in BD-I patients as compared with healthy controls (odds ratio =1.72 [95% confidence interval: 1.08-2.76, P=0.02]). In BD-I patients, the frequency of the five repeat allele was higher (allele frequency =0.41), and that of the four repeat allele lower (allele frequency =0.36) (χ (2)=4.634; P,0.03) than in the control group. No significant association was ...

Generation of Knockout Mice. The methods for generation of the knockout mice were as described in detail by Roberts et al. (2000). In brief, gene inactivation was obtained by disruption of the first coding exon of the μ-opioid receptor gene in 129/SV embryonic stem cells. Germline transmission occurred from the breeding of chimeric males with C57BL/6Orl females. After mice were genotyped, those showing germline transmission were used as founder animals to produce the F1 animals used in these experiments. We used male homozygous MOR KO and WT littermate mice (shipped from Scripps Research Institute, La Jolla, CA) in these experiments. The genetic background of these mice was a hybrid C57BL/6Orl × 129/SV strain. We housed mice one to three per cage in a temperature-controlled room in which the lights were on a 12-h light/dark cycle with lights off at 10:00 AM.. In Vitro Single-Cell Recordings. We used 4- to 5-month-old MOR KO and genetically intact WT littermate mice in this study. In some ...

Circadian disruption has been implicated in tumour development, but the underlying mechanism remains unclear. Here, we show that the molecular clockwork within malignant human pancreatic epithelium is disrupted and that this disruption is mediated by miR-135b-induced BMAL1 repression. miR-135b directly targets the BMAL1 3-UTR and thereby disturbs the pancreatic oscillator, and the downregulation of miR-135b is essential for the realignment of the cellular clock. Asynchrony between miR-135b and BMAL1 expression impairs the local circadian gating control of tumour suppression and significantly promotes tumourigenesis and resistance to gemcitabine in pancreatic cancer (PC) cells, as demonstrated by bioinformatics analyses of public PC data sets and in vitro and in vivo functional studies ...

Purpose: Sirtuins are a family of NAD-dependent deacetylase that are involved in a variety of cellular functions including metabolism, DNA repair, apoptosis, neuronal survival and inflammation. However, much of the sirtuins in the retina are largely unknown. In this study, we analyzed the mRNA levels of seven sirtuins (Sirt1-7) together with the sirtuin-associated molecules, and the effect of light-dark condition on the expression levels in the retina.. Methods: Six-week-old male C57BL6/J mice were used. The mice were kept under 12-h light/12-h dark (LD) cycle. After keeping under the usual LD cycle for 2 weeks, the mice were randomly divided into the LD group and constant darkness group (DD group). The DD group was transferred to constant darkness after the dark phase of the last LD cycle, and kept in the dark for two 24-hours DD cycles, and then, sacrificed during third 24-hours DD cycle. The retina and the liver of the LD and DD group mice were sampled every 4 hours, and brain parietal ...

LA JOLLA, CA-Scientists have known for some time that throwing off the bodys circadian rhythm can negatively affect body chemistry. In fact, workers whose sleep-wake cycles are disrupted by night shifts are more susceptible to chronic inflammatory diseases such as diabetes, obesity and cancer.. Researchers at the Salk Institute for Biological Studies have now found a possible molecular link between circadian rhythm disturbances and an increased inflammatory response. In a study published July 9 in Proceedings of the National Academy of Sciences, the Salk team found that the absence of a key circadian clock component called cryptochrome (CRY) leads to the activation of a signaling system that elevates levels of inflammatory molecules in the body.. There is compelling evidence that low-grade, constant inflammation could be the underlying cause of chronic diseases such as diabetes, obesity and cancer, says senior author Inder Verma, a professor in Salks Laboratory of Genetics and the Irwin and ...

Although sleep patterns change with age, it is the change in the ability to sleep that precipitates sleep complaints in older adults. Waking not rested, waking too early, trouble falling asleep, daytime napping, nocturnal waking, and difficulty initiating or maintaining sleep are among the chief sleep complaints of older adults. The consequences of poor sleep include difficulty sustaining attention, slowed response time, difficulty with memory, and decreased performance. Both medical and psychiatric conditions as well as the medications used to treat them lead to sleep complaints in older adults. Circadian rhythm disturbances and primary sleep disorders may also result in sleep complaints. Appropriate treatment may be dictated by severity of symptoms and concurrent medications. Efficacious pharmacologic interventions are the nonbenzodiazepine hypnotics zolpidem, zaleplon, and eszopiclone. Two new agents, ramelteon, which was recently approved by the U.S. Food and Drug Administration for use in ...

Previous studies have linked circadian rhythm disturbances with schizophrenia. However, Jonathan Sebat, PhD, of the University of California San Diego, and colleagues, did not purpose to analyze the VIP pathway genome; they by chance unearthed it as suspect during a broad spectrum genome analysis for copy number gains. The authors reported in the Feb. 24 issue of Nature that gene variants, described as microduplications on or around the gene for the vasoactive intestinal peptide (VIP) receptor, in patients with schizophrenia were 14 times as common relative to controls without mental illness. The researchers, commenting on the findings, said, While duplications of VIPR2 account for a small percentage of patients, the rapidly growing list of rare copy number variants that are implicated in schizophrenia suggests that this psychiatric disorder is, in part, a constellation of multiple rare diseases… This knowledge, along with a growing interest in the development of drugs targeting rare ...

30 In the absence of light input to the clock, nonphotic time cues are obviously a potential therapeutic option to treat non-24-hour circadian rhythms disorder. in the blind. There are currently no therapeutic guidelines, but some preliminary research suggests that it may be beneficial for patients to try to maintain a regular 24-hour schedule. Klerman Inhibitors,research,lifescience,medical and colleagues92 showed that the circadian system of a blind man with a period of 24.1 h became entrained when he lived on a 23.8 h day. AU aspects of his schedule were shifted simultaneously in this protocol including the sleep-wake cycle, meal times, activity, posture, and interaction with staff, precluding identification of the effective time signal, but collectively at least they were able to induce a phase advance. Other attempts to entrain circadian rhythms in blind people using a potential complex zeitgeber including exercise (bicycle riding, 50 W over 15 mins), a strict social routine, a cold ...

Somnolence (alternatively sleepiness or drowsiness) is a state of strong desire for sleep, or sleeping for unusually long periods (compare hypersomnia). It has distinct meanings and causes. It can refer to the usual state preceding falling asleep, the condition of being in a drowsy state due to circadian rhythm disorders, or a symptom of other health problems. It can be accompanied by lethargy, weakness, and lack of mental agility. Somnolence is often viewed as a symptom rather than a disorder by itself. However, the concept of somnolence recurring at certain times for certain reasons constitutes various disorders, such as excessive daytime sleepiness, shift work sleep disorder, and others; and there are medical codes for somnolence as viewed as a disorder. Sleepiness can be dangerous when performing tasks that require constant concentration, such as driving a vehicle. When a person is sufficiently fatigued, microsleeps may be experienced. In individuals deprived of sleep, somnolence may ...

Co-expression networks are a powerful tool to understand gene regulation. They have been used to identify new regulation and function of genes involved in plant development and their response to the environment. Up to now, co-expression networks have been inferred using transcriptomes generated on plants experiencing genetic or environmental perturbation, or from expression time series. We propose a new approach by showing that co-expression networks can be constructed in the absence of genetic and environmental perturbation, for plants at the same developmental stage. For this, we used transcriptomes that were generated from genetically identical individual plants that were grown under the same conditions and for the same amount of time. Twelve time points were used to cover the 24-h light/dark cycle. We used variability in gene expression between individual plants of the same time point to infer a co-expression network. We show that this network is biologically relevant and use it to suggest new gene

Hamsters. Male Syrian hamsters aged 8-10 weeks weighing between 100 and 110 g were obtained from Vital River Laboratories Company, Beijing, China. All animals were fed with an autoclaved laboratory rodent diet. The animals were maintained in a controlled environment under standard conditions of temperature and humidity with an alternating 12-h light/dark cycle in accordance with the regulations of the ethics committee and the Guide for the Care and Use of Laboratory Animals (The Ministry of Science and Technology of China, 2006). All animal experiments were approved by the Animal Committee of Nanjing Origin Biosciences, China (OB1511).. Induction of HBP carcinogenesis and treatment. Hamsters were randomized and divided into six groups of 8 animals each. Group 1 served as the normal control without any treatment.

Tg2576 transgenic mice (male and female) expressing Swedish mutated form of human APP (APPswe) (Hsiao et al., 1996) were bred in-house. All animals were maintained on a 12:12-h light/dark cycle with unrestricted access to food and water until use. Twenty-eight mice of 9.5 to 10.5 months of age were treated with CHF5074 (375 ppm in the diet) or standard diet (controls) for 17 weeks. At week 17, animals were sacrificed by decapitation, and brains were rapidly removed and divided in the two hemispheres. One hemisphere was used for measurements of Aβ plaques, and the other hemisphere was used for extractable Aβ. Blood samples were collected in EDTA-coated tubes and centrifuged at 800g for 20 min to separate plasma. Plasma samples were divided into two aliquots of approximately 100 μl each, and they were stored ...

Exercise has many well-established benefits to physical and mental health (25-30). The intensity, duration, frequency, mode, volume, and progression of exercise to optimize the beneficial effects have been well characterized (26, 44, 45). However, the proper timing of exercise and its potential added benefit of improving circadian entrainment have not been investigated thoroughly. Disruption of circadian rhythms (e.g., by shift work, social jetlag, early-morning schedules) is associated with metabolic disorders, cardiovascular disease, and cancer (6-11). If exercise could reduce circadian disruption, then it may also improve the risk factors associated with this disruption.. A tenet of the mammalian circadian system is that it is differentially sensitive to stimuli given at different times of day. Therefore, it is likely that the response of the internal circadian rhythm to exercise depends on the time of day of exercise. We chose morning and evening exercise for 2 reasons. First, morning ...

Learn how light and circadian disruption could be messing with your hormones, and how to ensure your body and brain can stay in sync with day and night.

Taken on my way home from a nightshift. Id been taking shots of a loch before sunrise but after the sun came up, the mist rose and I had to stop and try to shoot it. This is 3 lots of 3 portrait shots which were first edited in photomatix for tonal range then stitched together and toned down in elements. I dont enjoy over the top HDR landscapes but this one accurately reflects the scene I saw, with the possible exception of the sky which has that HDR yellow tinge I find hard to remove!
