Effects of endothelin on spontaneous contractions in lymph vessels. (1/75)

A mode of action of endothelin (ET) on spontaneous contractions was investigated in ring preparations of isolated bovine mesenteric lymphatics. ET-1 at concentrations between 10(-10) and 10(-9) M caused a dose-dependent increase in the frequency of spontaneous contractions. The specific ET(A)-receptor antagonist BQ-123 (5 x 10(-7) M) caused a significant inhibition of the ET-1-induced positive chronotropic effect in the ring preparations with and without the endothelium. Mechanical denudation of the lymphatic endothelial cells produced a significant potentiation of the ET-induced positive chronotropic effect. BQ-3020 (10(-8)-10(-7) M), a selective ET(B)-receptor agonist, induced dose dependently negative chronotropic and inotropic effects on the spontaneous contractions in the ring preparations with intact endothelium. Mechanical removal of the endothelium caused a significant reduction of the BQ-3020-induced negative chronotropic and inotropic effects. The ET-1-induced positive chronotropic effect was potentiated by pretreatment with N(omega)-nitro-L-arginine methyl ester (L-NAME) (10(-5) M) but unaffected by aspirin (10(-5) M). Additional treatment with L-arginine (10(-4) M) completely reversed the L-NAME-mediated potentiation of the ET-induced chronotropic effect. These results suggest that stimulation of ET(A) receptors on the lymphatic smooth muscles causes a positive chronotropic effect on the spontaneous contractions, and stimulation of ET(B) receptors on the lymphatic endothelial cells induces a release of nitric oxide, which results in the chronotropic and inotropic effects on spontaneous contractions in isolated bovine mesenteric lymphatics.  (+info)

Morningness/eveningness and the need for sleep. (2/75)

The purpose of this study was to determine, in a large sample of adults of all ages (17-80 years), the effect of morningness/eveningness on sleep/wake schedules, sleep needs, sleep hygiene and subjective daytime somnolence. A total of 617 subjects (219 subjects per chronotype group) matched for age, sex and employment status, completed an abridged morningness/eveningness questionnaire, a questionnaire on sleep habits and the quality of sleep, and the Epworth Sleepiness Scale. Eveningness was associated with a greater need for sleep, less time in bed during the week compared to ideal sleep needs, more time in bed at the weekend, a later bedtime and waking-up time especially at the weekend, more irregular sleep/wake habits and greater caffeine consumption. These subjects built up a sleep debt during the week and extended their duration of sleep at the weekend. They did not, however, rate themselves more sleepy than other types, despite the fact that our results showed a clear link between subjectively evaluated daytime somnolence and sleep debt. Why they were less affected by sleep deprivation is not clear. This raises the question of individual susceptibility to the modification of sleep parameters.  (+info)

Is the secretion of atrial natriuretic peptide in man under neural control? (3/75)

AIMS: Previous work has described short-term variation in the circulating plasma level of atrial natriuretic peptide (ANP), but the mechanism remains unknown. Our aim was to investigate the role of cardiac innervation in this variability. METHODS AND RESULTS: Blood samples were obtained from the right atrium via a pulmonary artery flotation catheter every 2 min over a 90 min period. Seven patients who underwent cardiac transplantation by the standard biatrial technique (partial innervation) and ten patients who underwent transplantation by the bicaval technique (total denervation) were studied. ANP levels were measured by radioimmunoassay. The median ANP levels were somewhat higher in the biatrial group compared to the bicaval group [470 (150-1095) vs. 216 (100-605) pg. ml(-1); median (range); P = ns], and both were much higher than normal levels in the pulmonary artery (40 (24, 56) pg ml(-1); median and interquartile range). In both transplant groups circulating plasma ANP levels showed considerable variability. The median number of 'peaks' and 'troughs', as counted by visual inspection, were not significantly different between the two groups. Computer analysis identified 12-16 and 6-15 'pulses' in the biatrial and bicaval group, respectively. Further analysis revealed that pulse amplitude, height and area were significantly higher in the biatrial compared to the bicaval group. CONCLUSION: It would appear that variability of circulating plasma levels of ANP is preserved despite complete or partial cardiac denervation, and so a neural mechanism does not appear to account for such variation.  (+info)

Basis for dosing time-dependent changes in the antiviral activity of interferon-alpha in mice. (4/75)

The influence of dosing time on the pharmacological effect (antiviral activity) of interferon-alpha (IFN-alpha), and the pharmacological and pharmacokinetic mechanisms, were investigated in ICR male mice under a 12-h light/dark cycle (lights on from 7:00 AM to 7:00 PM). 2'-5'Oligoadenylate synthetase activity in plasma at 24 h after IFN-alpha (10 MI.U./kg, i.v.) injection, as an index of antiviral activity, was significantly higher for injections given at 9:00 AM than for injections given at 9:00 PM (P <.05). The uptake of [(3)H]thymidine by lymphocytes after 24-h incubation with IFN-alpha, as an index of lymphocyte-stimulating effect, was significantly higher in cells obtained at 9:00 AM than in the cells obtained at 9:00 PM (P <.01). The number of receptors per cell and the expression of interferon-stimulated gene factor in lymphocytes after 24-h incubation with IFN-alpha were significantly higher in the cells obtained at 9:00 AM than at 9:00 PM (P <.05). A significant dosing time-dependent difference was demonstrated for the pharmacokinetic parameters of IFN-alpha, which showed higher clearance for injections given at 9:00 PM than for those at 9:00 AM (P <.05). The metabolism of IFN-alpha was significantly higher in kidney obtained at 9:00 PM than at 9:00 AM (P <.05). These findings support that choosing the most appropriate time of day for administration of IFN-alpha, associated with the rhythmicity of IFN-alpha receptor function and IFN-alpha pharmacokinetics, may increase the antiviral activity in experimental and clinical situations.  (+info)

Biological time and in vivo research: a field guide to pitfalls. (5/75)

Biological rhythmicity is a fundamental characteristic of all life forms, from primitive bacteria to man. The molecular biology, genetics, and the neurobiology of the biological clock(s) are being elucidated. Daily (circadian) statistically significant fluctuations occur in all of the normal biological variables studied in the experimental animal and the human. Many researchers, however, are not aware of the negative impact biological rhythmicity can have on experimental design and/or data interpretation. This article serves not as a review, but as a "field guide" to the pitfalls that can occur when research is performed in the absence of an understanding of biological rhythmicity. The major topics discussed are: 1) data transfer from the diurnally in-active/resting/sleeping lab animal to the diurnally active human, 2) frequency of sampling, 3) free-running vs. synchronization, 4) alternating periods of resistance and susceptibility, 5) phase shifting of a rhythm, 6) the assumption that one mean +/- S.E. from control animals can be "stretched" across an experimental time span, and 7) plotting data on an "hours after treatment" format vs. a "time of day" format. The hope is that by avoiding the pitfalls, biological time will become an ally in the endeavor to understand human biology.  (+info)

The temporal organization of life: the impact of multi-frequency non-linear biologic time structure upon the host-cancer balance. (6/75)

The current scientific paradigm, based upon an erroneous assumption of linear biologic reality and simple cause and effect relationships, has outlived its usefulness. In order to begin to turn the voluminous data the reductive process provides us with daily into meaningful understanding of life, it is essential to integrate these data within a complex, multi-frequency temporo-spatial framework. This rhythmic chronobiology more accurately depicts the life process, as well as its evolutionary and ongoing vital interaction with the pulsating cosmic resonance structure. Examples of the kinds of thinking and experiments necessary to exploit this new paradigm are provided.  (+info)

Diurnal variations of post-exercise parasympathetic nervous reactivation in different chronotypes. (7/75)

The purpose of this study was to investigate the diurnal variation and chronotype differences, i.e., in morning-types and evening-types, in post-exercise vagal reactivation. Twelve healthy male college students who were classified as morning-type (6) and evening-type (6), based on responses to a questionnaire, participated in this study. Postexercise vagal reactivation was assessed as the time constant of the beat-by-beat heart rate decrease for the first 30 sec after exercise (T30) at an intensity lower than the ventilatory threshold. The subjects performed 3-min cycle ergometer exercise at an intensity corresponding to 80% of the ventilatory threshold after a 1 min warm-up exercise in the morning (7:00 - 8:00) and evening (17:00 - 18:00) to obtain the T30. A significant interaction (chronotype-by-time) effect was found for T30. The morning value of the T30 in evening-type subjects was significantly larger than their evening value and the morning value in morning-type subjects. There was no significant interaction effect for heart rate and oxygen uptake during exercise. These results suggest that diurnal variation in post-exercise vagal reactivation is different between morning-type and evening-type, and post-exercise vagal reactivation in evening-type individuals is sluggish in the morning.  (+info)

The brain decade in debate: IV. Chronobiology. (8/75)

The present article is the adapted version of an electronic symposium organized by the Brazilian Society of Neuroscience and Behavior (SBNeC) which took place on June 14, 2000. The text is divided into three sections: I. The main issues, II. Chronodrugs, and III. Methods. The first section is dedicated to the perspectives of chronobiology for the next decade, with opinions about the trends of future research being emitted and discussed. The second section deals mostly with drugs acting or potentially acting on the organism's timing systems. In the third section there are considerations about relevant methodological issues concerning data analysis.  (+info)

Chronobiology is the study of biological rhythms. It examines the effects of time on biological events and internal biological clocks. Over the past few decades, chronobiology has developed into a multidisciplinary field of interest in general medicine and psychiatry (1). Research on chronobiology is constantly growing and has contributed to the development of an interdisciplinary field of research. The Nobel Prize in Medicine in 2017 was awarded to scientists who investigated molecular mechanisms that control circadian rhythms.. The earths rotation and the daily light-dark or day-night cycle have had long and constant biological impacts on the earths living organisms. Over the long evolutionary process, organisms have developed clock-like structures. These biological clocks help organisms successfully perform their activities over a 24-h cycle. This adaptive ability predicts cyclic changes and allows behavioral and physiological harmonization. These endogenous clocks are useful because they ...

Cycles of Nature: Introduction - Halberg Chronobiology Center
The science of chronobiology quantifies the time structure characterizing each physiologic variable, its genetically anchored and mostly environmentally synchronized chronome. Thereby, one gains new information and thus a new dimension to the care of ones health and the integrity of ones environment. The importance of chronobiologic information has been compared with the importance of the energy released by splitting the atom. This science ushers in a new era by allowing one to do more than asking only whether a time-unspecified measurement or a series of such casual measurements or even a series of systematic measurements covering a day or a week is too high or too low. Instead, one can rely on a rhythm-adjusted mean (the MESOR) that as compared to the arithmetic mean is more accurate and more precise. As a dividend (which may be more important under certain conditions than the best average value), chronobiology also pro- vides new information on the extent of predictable since rhythmic changes (the

In life, timing is everything. There is a new buzzword in cancer therapy, Chronobiology. Simply put, this means the study of clocklike stuff in living things. Or you can use the brainier definition, Chronobiology is the quantitative study of rhythmic temporal relationships in biological phenomena. Our bodies go through a day as if multiple clocks were hardwired into our brains, organs, and very cells telling us what to do and when to do it. In recent years scientists have just begun to understand these multiple rhythms of activity and rest that different systems in the body go through on a daily basis. These daily, or circadian, cycles repeat themselves every 24 hours. Cells dont grow at a constant rate; rather there are bursts of frantic cell division followed by rest spells. Hormones are not generated at a steady flow rate but have high points when they are dumped into the blood and low points throughout the day. All animals have built in clocks in not just their bodies but in their ...

Rat ECG and general anesthesia: A chronobiological study | International Journal of Current Research
This investigation aimed to review the initial state of electrophysiological parameters that may predict the development of heart rhythm disorders in spontaneously-breathing pentobarbital-, ketamine-xylazine- and zoletil-anesthetized rats. These data will contribute to building a wider framework for a chronobiological perspective on the dependence of these parameters on the light-dark (LD) cycle under in vivo conditions. The study was performed using female Wistar rats, which were adapted to a 12 h LD cycle. Parameters evaluated included RR, PQ, QT, QTc intervals, the QRS complex and the amplitudes of P, R and T waves. The longest RR and QT interval duration occurred after the administration of ketamine-xylazine anesthesia in both the light period and the dark period. The longest PQ and QTc interval durations occurred under zoletil anesthesia in the light period. It is concluded that from a chronobiological perspective, the most significant electrophysiological myocardial susceptibility toward ...

A. External cues (other than the entraining stimulus) that might provide timing stimuli to the animal should be avoided. This might seem axiomatic. For example, the most important entraining stimulus for mammals is light. As a result, most circadian biologists would not accept any phenomenon as circadian in nature unless it was demonstrated in continuous darkness (DD).. Nevertheless, this standard is often not observed. For example in the original studies demonstrating food entrainment (see review by Stephan [3]), animals were permitted to remain on a light-dark (LD) cycle. While the use of LD insured that the light entrained rhythm and the food entrained rhythm would remain temporally separated, the light also provides a temporal cue for food presentation. A number of recent food entrainment studies including those by Mistlberger in which he has done dorsomedial hypothalamic (DMH) lesions [4, 5], have continued to be performed only under LD. However, if animals are entrained under LD, and food ...

abstract = {Under sleep loss, vigilance is reduced and attentional failures emerge progressively. It becomes difficult to maintain stable performance over time, leading to growing performance variability (i.e., state instability) in an individual and among subjects. Task duration plays a major role in the maintenance of stable vigilance levels, such that the longer the task, the more likely state instability will be observed. Vulnerability to sleep-loss-dependent performance decrements is highly individual and is also modulated by a polymorphism in the human clock gene PERIOD3 (PER3). By combining two different protocols, we manipulated sleep-wake history by once extending wakefulness for 40 h (high sleep pressure condition) and once by imposing a short sleep-wake cycle by alternating 160 min of wakefulness and 80 min naps (low sleep pressure condition) in a within-subject design. We observed that homozygous carriers of the long repeat allele of PER3 (PER35/5) experienced a greater time-on-task ...

The evolving science of Chronobiology demonstrates that all body systems have a biorhythm or circadian rhythm that serve as physiological indicators that have a timing effect on specific systems metabolism. Nutrients and drugs give a more desired effect when given at a time that best matches this metabolism. This is called Chronobiology and is generating clinical studies that demonstrate certain drugs have a significantly different result if given in the AM as opposed to the PM. For example, since the liver is regenerating itself on a daily circadian basis in the early morning, antioxidants (i.e. Glutathione, N-Acetylcysteine) to help strengthen and support the liver are given in the IDNutrition™ PM packet.

Effects of Ramadan on physical performance: chronobiological considerations | British Journal of Sports MedicineEffects of Ramadan on physical performance: chronobiological considerations | British Journal of Sports Medicine
The suprachiasmatic nuclei (SCN) of the hypothalamus are the site of the body clock.29 These clusters of cells are linked to the eyes via the direct retinohypothalamic tract and receive a humoral input from the pineal gland, which secretes the hormone melatonin during the hours of darkness. Melatonin has many effects throughout the body, reviewed in an exercise physiology context by Atkinson et al.30 One of melatonins properties is that it is a potent vasodilator and so promotes heat loss. The evening fall of body temperature is caused by the body clock and the onset of melatonin secretion; the morning rise in body temperature is due to the combined effects of the body clock and an inhibition of melatonin secretion (secretion being suppressed by bright light). Melatonin induces drowsiness through its effect upon body temperature and also via a direct central action.. The rhythmic neural and humoral inputs to the SCN (showing a period of 24 h) enable the phase of the body clock to be adjusted to ...

Some chronobiological considerations related to physical exercise. - STORE - Staffordshire Online RepositorySome chronobiological considerations related to physical exercise. - STORE - Staffordshire Online Repository
Variables associated with physical activity show circadian rhythms in resting subjects; these rhythms have both exogenous (due to the individuals lifestyle and environment) and endogenous (due to the body clock) components. During exercise, many of the rhythms persist, even though some show decreasing amplitude with increasing severity of exercise. Whilst the value of physical fitness is not disputed (for elite athletes, for individuals who just want to be physically fit, or for patients undertaking physical rehabilitation regimens), there are certain times of the day when special care is needed. These times are soon after waking--when there is the possibility of an increased risk of cardiovascular morbidity and damage to the spine--and late in the day--when there is an increased risk of respiratory difficulties. Since physical exercise is inextricably linked with thermoregulation, there are special considerations to bear in mind when exercise takes place in cold or hot environments. Further, ...

The time of maximum activity of kapha is during morning and evening from about 6 to 10 a.m. and 6 to 10 p.m. The pitta period is during midday and midnight, from about 10 a.m. to 2 p.m. and 10 p.m. to 2 a.m., while vata hours are dawn and dusk, from about 2 to 6 a.m. and p.m. Thus a pitta-type disease such as ulcers may cause the most discomfort late at night in pitta time. The reverse is also true, in the sense that experiencing a sharp pain in the stomach region late at night may signify ulcers or another pitta disorder.. Avastha Paka Kala means the time for the different stages of digestion, which is also biological time. When you eat food, it passes through various stages of digestion, each one governed primarily by one taste and a specific dosha. To digest a major meal takes approximately six hours or more. For the first ...

Metabolic Arrest and the Control of Biological Time - Peter W. Hochachka, Michael Guppy | Harvard University Press
What mechanisms turn down (or off) cell metabolism and other cell functions? How does an animal such as an opossum know when to activate mechanisms for slowing or stopping tissue and organ functions? These capabilities raise important questions, which Peter Hochachka and Michael Guppy explore in this seminal new book. This is a pioneering book of great use to biomedical/clinical researchers and to biologists, biochemists, and physiologists generally.

Chrono refers to time and biology refers to the study of life. Chronobiology thus denotes a lifestyle according to specific changes in time, like the day/night cycle, which are innate to your body. Human beings have 2 types of internal clocks that set the preferred pace for our biological rhythms. These clocks subconsciously tell you when to eat, sleep, regulate temperature, produce hormones, and even move your body.. The first internal timekeeper, known ast the Central clock, is related to the light/dark cycle. Through the activity in your suprachiasmatic nucleus found in your hypothalamus, your body aligns with the earths rotation around the sun to stay on a regular 24-hour cycle.. The second timekeeper, the Peripheral Clocks, are found in each of the tissues within your body, e.g. digestive organs, pancreas, muscles, adrenals, kidneys, etc. Ideally, these timekeepers prefer your tissues to operate in a certain way at a certain time. For example, your digestive organs may work best resting ...

Neurobehavioral Consequences of Sleep Dysfunction | Psychiatric TimesNeurobehavioral Consequences of Sleep Dysfunction | Psychiatric Times
As chief of the division of sleep and chronobiology in the department of psychiatry at the University of Pennsylvania School of Medicine, David F. Dinges, Ph.D., focuses on ways sleep and the endogenous circadian pacemaker interact to control wakefulness and waking neurobehavioral functions such as physiological alertness, attention, cognitive performance, fatigue, mood, neuroendocrine profiles, immune responses and health. In an interview with Psychiatric Times, Dinges discussed neurobehavioral consequences of sleep loss, factors that impair sleeping, the pervasiveness of sleepiness and new ways to manage sleepiness. 1

Quantum Biology 12: Do We Need DNA To Tell Time? - Dr. Jack KruseQuantum Biology 12: Do We Need DNA To Tell Time? - Dr. Jack Kruse
The clock in the SCN is the major controller overall for timing, but when we face environmental mismatches that specifically involve the use of any particle/waveform tied to QED, it increases the likelihood that we can have desynchronization of the SCN from the peripheral clocks. It appears the brain has a dual timing mechanism. It has the older analog clock that responds in a graded fashion to one photon of light of many. The SCN and Pineal gland seem to be big players in the analog system. The retina and visual apparatus are the newer part of the clock called the digital system. They use a binary code of off and on with light. The action potential of the optic nerve is all or none. When light is present at the human eye ROS and ELF-UV light is released from cells. (van Wijk). When we have desynchronization of the SCN from the peripheral organ clocks, we call this a phase shift in chronobiology. This is how we lose track of Quantum time (small time) that I mentioned in EMF 6. Moreover, this ...

Ronald J. Konopka - WikipediaRonald J. Konopka - Wikipedia
Ronald J. Konopka (1947-2015) was an American geneticist who studied chronobiology. He made his most notable contribution to the field while working with Drosophila in the lab of Seymour Benzer at the California Institute of Technology. During this work, Konopka discovered the period (per) gene, which controls the period of circadian rhythms. Ron Konopka received his Ph.D. in Biology from the California Institute of Technology in 1972. In 1975, following his discovery of the period mutants, Konopka was awarded a faculty position at the California Institute of Technology. While there, Konopkas colleagues were critical of his reluctance to publish his work on the period gene, and Konopka was denied tenure. After his stay at Caltech, Konopka accepted a position at Clarkson University but was again denied tenure and subsequently exited the field of science. Konopkas career, interwoven with the work of his mentor, Seymour Benzer, and the other scientists working in Benzers lab is narrated in Time, ...

What happens to your body when you fall asleep? | SciencelineWhat happens to your body when you fall asleep? | Scienceline
Its a disorienting experience to be awakened by a phone call while curled up for a good nights sleep. Hearing muffled fumbling for the phone followed by a groggy greeting, the caller usually asks, Oh, were you sleeping?. My most common answer is, I dont know. No. Im not sure. In that state of confusion, the last thing Im capable of is analyzing the inner workings of my body to understand if I am awake or asleep. Luckily, there is a lot of science to explain what it really means to be asleep, and what happens to get us there.. There is no universally agreed-upon definition because falling asleep is not a split-second occurrence, not an abrupt switch from awake to asleep. Rather, it is a gradual progression of stages in which body and brain activity changes.. Sleep onset is sort of a reflection of your brain switching from one way of thinking to another way of thinking, says Scott Campbell of the Cornell Medical School Laboratory of Human Chronobiology. Besides brain activity, sleep ...

Differences in circadian patterns between rural and urban populations: an epidemiological study in countryside | Read by QxMDDifferences in circadian patterns between rural and urban populations: an epidemiological study in countryside | Read by QxMD
The physiological pattern of the sleep-wake cycle is influenced by external synchronizing agents such as light and social patterns, creating variations in each individuals preferred active and sleep periods. Because of the demands of a 24-h working society, it may be imperative for many people to adapt their sleep patterns (physiologically) to their daily activities. Therefore, we analyzed the difference in sleep patterns and chronobiological parameters between an essentially rural farming and urban small-town populations. We studied 5942 subjects (women, 67.1%, N = 3985; mean age, 44.3 ± 13.1 years), from which the chronotype, circadian sleep pattern, and period of light exposure were collected using the Munich Chronotype Questionnaire (MCTQ). A structured questionnaire was also made for collection of social and demographic information. Compared with the urban population (N = 3427, 57.7%), the rural population (N = 2515, 42.3%) presented a more predominantly early sleep pattern, as determined ...

TIME #6: IS BIOLOGIC TIME LINKED TO DOPAMINE LEVELS? - Dr. Jack KruseTIME #6: IS BIOLOGIC TIME LINKED TO DOPAMINE LEVELS? - Dr. Jack Kruse
Tyrosine is one of 3 aromatic amino acids. All aromatic amino acids are relatively nonpolar. To different degrees, all aromatic amino acids absorb ultraviolet light. Tyrosine and tryptophan absorb more than do phenylalanine; tryptophan is responsible for most of the absorbance of ultraviolet light ( 280 nm = UV) by proteins. Tyrosine is the only one of the aromatic amino acids with a photo-ionizable side chain. Tyrosine is one of three hydroxyl-containing amino acids. When dopamine is made any other way chemically or substrate substituted the brain and cells cannot control its concentration properly and many side effects result. It turns out other chemicals with disulfide bonds are critical in working properly with dopamine. When it is made by the interaction between UV light and tyrosine as designed by nature the perfect balance occurs photo-chemically. This is why taking exogenous glutathione is risky. The amount of light released has to be quantized with other chemicals in the local cell ...

Targeting the biological clock could slow the progression of cancerTargeting the biological clock could slow the progression of cancer
Published in the journal BMC Biology, these results show for the first time that directly targeting the biological clock in a cancerous tumour has an impact on its development.. Most of the cells in the human body have an internal clock that sets a rhythm for the activities of our organs according to the time of the day. Cancer cells, however, often have a non-functioning or malfunctioning clock.. There were indications suggesting that the malfunctioning clock contributed to rapid tumour growth, but this had never been demonstrated. Thanks to the use of a chemical or a thermic treatment, we succeeded in repairing these cells clock and restoring it to its normal functioning. In these conditions, tumour growth drops nearly in half, explains Cermakian, who is also Director of the Laboratory of Molecular Chronobiology at the Douglas Mental Health University Institute, one of the research centres of the CIUSSS de lOuest-de-lÎle-de-Montréal.. Although this preclinical demonstration was done ...

Vincent Cassone | BiologyVincent Cassone | Biology
Chronobiology and Neuroscience Research in the Cassone laboratory is directed at the mechanisms and neuroendocrine pathways by which the biological clock regulates physiology and behavior in vertebrates, especially in birds. All eukaryotic and at least some prokaryotic organisms express a temporal organization as well as a spatial organization such that many molecular, physiological and behavioral events are strictly timed. This temporal organization reflects a biological clock derived primarily from endogenous cellular oscillators that are somehow coupled or entrained to the prevailing environmental cycles. Recently, we have become interested inmechanisms by which the circadian clock regulates gastrointestinal function. Part of this research has revealed an enteric bacterium, Klebsiella aerogenes, that exhibits a circadian rhythm in swarming behavior and gene expression. We are investigating the mechanisms that generate circadian rhythms in this bacterial organism. Students in the laboratory ...

This is a little tough for the reason that dopamine molecule itself cant cross the blood-brain barrier - but its precursor, levodopa, can. Since the 1970s, the first medication for motor signs of Parkinsons has been a mix of levodopa and carbidopa (carbidopa/levodopa; brand name is Sinemet).. Though it is one of the commonest mental health issues within the country, depression is greater than merely feeling unhappy. Clinical melancholy and main depressive problems affect the person on cognitive, psychological and bodily levels. Like many other psychological disorders, we must always view despair as a illness that encompasses a spectrum of causes and symptoms. Risk elements like a family historical past of despair, physical diseases, drugs and main trauma or stress can influence or advance the onset of a depressive episode.. In individuals with solely mild hallucinations that are properly tolerated, lively antipsychotic therapy will not be essential. Although no particular remedy exists for ...

Except for a handful of forward-thinking school districts, the continuing resistance to starting high school later to accommodate the biological time clocks of teenagers speaks to the attitudes of the adults in charge of our children. How can it be that despite overwhelming evidence that sleep deprivation in teenagers is every bit the public health menace that cigarette smoking is, school administrators have abided the status quo?Sleep researchers have convincingly demonstrated that, on average, teenagers need nine hours of sleep and that their brains are programmed for them to stay up later than adults. Sleep researchers have also convincingly demonstrated that, on average, adults need eight hours of sleep. Not getting enough sleep is as pervasive in todays culture as was consuming two or three packs per day of Lucky Strikes in the 1940s, 50s and 60s.

Epigenetic Memories are Passed Down 14 Successive GenerationsEpigenetic Memories are Passed Down 14 Successive Generations
The past of our ancestors lives on through us: Groundbreaking research illustrates how parental experience is not only epigenetically imprinted onto offspring, but onto an unprecedented number of future generations. Rather than occurring over the elongated time scale of millions of years, genetic change can transpire in real biological time through nanoparticles known as exosomes.. Until recently, it was believed that our genes dictate our destiny. That we are slated for the diseases that will ultimately beset us based upon the pre-wired indecipherable code written in stone in our genetic material. The burgeoning field of epigenetics, however, is overturning these tenets, and ushering in a school of thought where nurture, not nature, is seen to be the predominant influence when it comes to genetic expression and our freedom from or affliction by chronic disease..

Review of Steve Meyers New Book, Darwins Doubt | The Christian Scientific SocietyReview of Steve Meyers New Book, Darwins Doubt | The Christian Scientific Society
I should have known better; science marches onward, and old arguments get reexamined as new data arises. Steve Meyers book is a wonderful, comprehensive case that the origin of the major types of animals, namely the phyla, is just as strikingly discontinuous as the origin of life. As such, it represents a solid second volume complementary to his previous work, Signature in the Cell, which focused on the origin of life.. I had come to think that discussing the Cambrian Explosion was misguided because of two arguments: 1) that the explosion was merely an artifact of the fact that organisms before that time did not have hard bones or shells, and 2) that the explosion was short on the geological time scale, but was really quite long on the biological time scale. Meyer disposes of both of these arguments quite handily. On the first, modern science shows that soft-bodied organisms are well preserved in the strata before, during, and after the Cambrian. Also, many of the body types which appear in the ...

I will carry out my genetiX snowball action during daylight on the first or third weekend of every month.. The reason for this fixed time structure is to give the genetiX snowball some kind of momentum, a possibility to increase in size over time and so that snowballers can choose the best time for their own group. Lots of groups of people all acting at the same time builds a sense of community, shows a unified presence and will carry stories better in the local and national media. The dates are set at weekends to allow the majority of people who work regular hours to participate more easily. It also gives space for people from other campaigns to do other kinds of actions.. We would like to develop a relationship of mutual trust and respect with the farmers and they are more likely to be reassured if they know when to expect us.

From Body to Bank Account; Does Sleep Contribute to Success? | Sleep Scholar
German researchers looked at the brain functions of night owls (those who go to bed late) and larks (those tucked in early) and found some distinct differences.. According to the report, the differences could have a huge effect on life, success, and overall personality. Dr Jessica Rosenberg of the Institute of Neuroscience and Medicine in Jülich, Germany says: Our results show that extreme late chronotypes (night owls) show differences in the diffusion of water molecules in areas belonging to the white matter of the brain as compared to early and intermediate chronotypes (larks).. Reporter Áilín Quinlan writes that diffusion difference could be linked to depression in owls, who suffer a kind of jet lag by being forced to reluctantly participate in a world of early risers which is in conflict with their natural tendency to sleep late.. Late-nighters may find their lifestyles bring on more than a case of the blues, writes Quinlan. Studies carried out at the University of Western ...
