Neural changes after operant conditioning of the aerial respiratory behavior in Lymnaea stagnalis. (1/175)

In this study, we demonstrate neural changes that occurred during operant conditioning of the aerial respiratory behavior of Lymnaea stagnalis. Aerial respiration in Lymnaea occurs at the water interface and is achieved by opening and closing movements of its respiratory orifice, the pneumostome. This behavior is controlled by a central pattern generator (CPG), the neurons of which, as well as the motoneurons innervating the pneumostome, have previously been identified and their synaptic connections well characterized. The respiratory behavior was operantly conditioned by applying a mechanical stimulus to the open pneumostome whenever the animal attempted to breathe. This negative reinforcement to the open pneumostome resulted in its immediate closure and a significant reduction in the overall respiratory activity. Electrophysiological recordings from the isolated CNSs after operant conditioning showed that the spontaneous patterned respiratory activity of the CPG neurons was significantly reduced. This included reduced spontaneous activity of the CPG interneuron involved in pneumostome opening (input 3 interneuron) and a reduced frequency of spontaneous tonic activity of the CPG interneuron [right pedal dorsal 1 (RPeD1)]. The ability to trigger the patterned respiratory activity by electrical stimulation of RPeD1 was also significantly reduced after operant conditioning. This study therefore demonstrates significant changes within a CPG that are associated with changes in a rhythmic homeostatic behavior after operant conditioning.  (+info)

Scanning electron microscopy of the lateral cell surfaces of rat incisor ameloblasts. (2/175)

Dry dissected rat incisor ameloblasts studied in the scanning electron microscope show remarkable specializations of their lateral surfaces. Four or five cycles of a change from a surface with longitudinal gutterlike folds associated with large intercellular spaces, to one with microvilli and reduced intercellular spaces, are found along the length of the lower incisor maturation zone. It is argued that these changes indicate cyclical activity in maturation ameloblasts.  (+info)

Many LH peaks are needed to physiologically stimulate testosterone secretion: modulation by fasting and NPY. (3/175)

The pulsatile luteinizing hormone (LH) and testosterone secretions were studied during serial blood collections performed at 7-min time intervals in the male rat. In fed rats, a discontinuous pattern of LH secretion was observed. Periods without secretion alternated with active secretory episodes consisting in trains of three to four LH peaks that triggered testosterone secretion usually 1-2 h later. The magnitude of the testosterone response was not correlated with the amplitude of the LH peaks. Isolated, single peaks of LH did not evoke clear testosterone responses. Forty-eight hours after initiation of fasting, testosterone secretion was markedly decreased, but integrated LH secretion was only partly reduced. Chronic infusion of neuropeptide Y (NPY; 18 microgram/day, icv) reduced testosterone secretion to very low levels and abolished pulsatile LH secretion or testosterone response to isolated LH peaks. In conclusion, the stimulation of testosterone secretion by LH necessitates several LH peaks organized in a proper sequence, and the testosterone response is not immediate. Low testosterone secretion in fasting rats appears to result from disappearance of coordinated, multiple LH peaks of sufficient size. Inhibition of the gonadotropic axis achieved by central NPY administration is due to either absence of LH peak "clusters" or occurrence of nonfunctional single LH peaks.  (+info)

Activity patterns and synaptic organization of ventrally located interneurons in the embryonic chick spinal cord. (4/175)

To investigate the origin of spontaneous activity in developing spinal networks, we examined the activity patterns and synaptic organization of ventrally located lumbosacral interneurons, including those whose axons project into the ventrolateral funiculus (VLF), in embryonic day 9 (E9)-E12 chick embryos. During spontaneous episodes, rhythmic synaptic potentials were recorded from the VLF and from spinal interneurons that were synchronized, cycle by cycle, with rhythmic ventral root potentials. At the beginning of an episode, ventral root potentials started before the VLF discharge and the firing of individual interneurons. However, pharmacological blockade of recurrent motoneuron collaterals did not prevent or substantially delay interneuron recruitment during spontaneous episodes. The synaptic connections of interneurons were examined by stimulating the VLF and recording the potentials evoked in the ventral roots, in the VLF, or in individual interneurons. Low-intensity stimulation of the VLF evoked a short-latency depolarizing potential in the ventral roots, or in interneurons, that was probably mediated mono- or disynaptically. At higher intensities, long-latency responses were recruited in a highly nonlinear manner, eventually culminating in the activation of an episode. VLF-evoked potentials were reversibly blocked by extracellular Co2+, indicating that they were mediated by chemical synaptic transmission. Collectively, these findings indicate that ventral interneurons are rhythmically active, project to motoneurons, and are likely to be interconnected by recurrent excitatory synaptic connections. This pattern of organization may explain the synchronous activation of spinal neurons and the regenerative activation of spinal networks when provided with a suprathreshold stimulus.  (+info)

Lispro or regular insulin for multiple injection therapy in adolescence. Differences in free insulin and glucose levels overnight. (5/175)

OBJECTIVE: Regular insulin given with the evening meal could contribute to the risk of nocturnal hypoglycemia in adolescents with type 1 diabetes using a multiple injection regimen. To test this hypothesis, we compared glucodynamics and free insulin levels on two separate study nights. RESEARCH DESIGN AND METHODS: A total of 14 adolescents were recruited. On both nights, identical doses of regular insulin or insulin lispro were administered 30 min or 10 min, respectively, before the evening meal, using a double-blind randomized crossover study design. Doses of NPH insulin and carbohydrate content of the evening meal and snack were kept identical. Blood samples were taken every 15 min for blood glucose and every 60 min for free insulin and ketones. RESULTS: After insulin lispro administration, glucose levels were significantly lower between the evening meal and the bedtime snack (analysis of variance [ANOVA] P = 0.02), and four hypoglycemic episodes were recorded. This corresponded to a higher (458 +/- 48 vs. 305 +/- 33 pmol/l, P = 0.02), earlier (64 +/- 4.6 vs. 103 +/- 12 min, P = 0.01), and shorter-lasting (245 +/- 21 vs. 365 +/- 39 min, P = 0.01) insulin peak in contrast to regular insulin. After the bedtime snack, glucose levels increased dramatically during the lispro night and stayed higher, up to 0300 in the morning (ANOVA P = 0.01), corresponding to lower mean insulin levels (146 +/- 20 vs. 184 +/- 27 pmol/l, P = 0.04). No differences were seen in glucose and insulin levels between 0300 and 0800. Four episodes of nocturnal hypoglycemia were documented after the bedtime snack during the regular insulin night, in contrast to one episode after insulin lispro. No differences in ketone levels were observed. CONCLUSIONS: The replacement of regular insulin with insulin lispro may reduce the risk of late hypoglycemia, but redistribution of the evening carbohydrate may be needed to ensure good metabolic control and prevent early postprandial hypoglycemia.  (+info)

Intracellular Ca(2+) oscillations in luteinizing hormone-releasing hormone neurons derived from the embryonic olfactory placode of the rhesus monkey. (6/175)

To understand the mechanism of pulsatile luteinizing hormone-releasing hormone (LHRH) release, we examined whether cultured LHRH neurons exhibit spontaneous intracellular Ca(2+) ([Ca(2+)](i)) signaling. The olfactory placode and the ventral migratory pathway of LHRH neurons from rhesus monkey embryos at embryonic ages 35-37 were dissected out and cultured on glass coverslips. Two to five weeks later, cultured cells were labeled with fura-2 and examined for [Ca(2+)](i) signaling by recording changes in [Ca(2+)](i) every 10 sec for 30-175 min. Cells were fixed and immunostained for LHRH and neuron-specific enolase. In 20 cultures, 572 LHRH-positive cells exhibited [Ca(2+)](i) oscillations at an interpulse interval (IPI) of 8.2 +/- 0.7 min and a duration of 88.8 +/- 2.9 sec. LHRH-negative neurons in culture exhibited only occasional [Ca(2+)](i) oscillations. In 17 of 20 cultures with LHRH-positive cells, [Ca(2+)](i) oscillations occurred synchronously in 50-100% of the individual cells, whereas [Ca(2+)](i) oscillations in cells in the remaining three cultures did not synchronize. Strikingly, in 12 of 17 cultures the synchronization of [Ca(2+)](i) oscillations repeatedly occurred in complete unison at 52.8 +/- 3.0 min intervals, which is similar to the period observed for LHRH release, whereas in 5 of 17 cultures the less tight synchronization of [Ca(2+)](i) oscillations repeatedly occurred at 23.4 +/- 4.6 min intervals. IPI of [Ca(2+)](i) oscillations in cells with tight synchronization and less tight synchronization did not differ from IPI in cells without synchronization. The results indicate that LHRH neurons derived from the monkey olfactory placode possess an endogenous mechanism for synchronization of [Ca(2+)](i) oscillations. Whether synchronization of [Ca(2+)](i) oscillations relates to neurosecretion remains to be investigated.  (+info)

Oscillatory behavior of a simple kinetic model for proteolysis during cell invasion. (7/175)

Extracellular proteolysis during cell invasion is thought to be tightly organized, both temporally and spatially. This work presents a simple kinetic model that describes the interactions between extracellular matrix (ECM) proteins, proteinases, proteolytic fragments, and integrins. Nonmonotonous behavior arises from enzyme de novo synthesis consecutive to integrin binding to fragments or entire proteins. The model has been simulated using realistic values for kinetic constants and protein concentrations, with fibronectin as the ECM protein. The simulations show damped oscillations of integrin-complex concentrations, indicating alternation of maximal adhesion periods with maximal mobility periods. Comparisons with experimental data from the literature confirm the similarity between this system behavior and cell invasion. The influences on the system of cryptic functions of ECM proteins, proteinase inhibitors, and soluble antiadhesive peptides were examined. The first critical parameter for oscillation is the discrepancy between integrin affinity for intact ECM proteins and the respective proteolytic fragments, thus emphasizing the importance of cryptic functions of ECM proteins in cell invasion. Another critical parameter is the ratio between proteinase and the initial ECM protein concentration. These results suggest new insights into the organization of the ECM degradation during cell invasion.  (+info)

Circadian rhythms in the suprachiasmatic nucleus are temperature-compensated and phase-shifted by heat pulses in vitro. (8/175)

Temperature compensation and the effects of heat pulses on rhythm phase were assessed in the suprachiasmatic nucleus (SCN). Circadian neuronal rhythms were recorded from the rat SCN at 37 and 31 degrees C in vitro. Rhythm period was 23.9 +/- 0.1 and 23.7 +/- 0.1 hr at 37 and 31 degrees C, respectively; the Q(10) for tau was 0.99. Heat pulses were administered at various circadian times (CTs) by increasing SCN temperature from 34 to 37 degrees C for 2 hr. Phase delays and advances were observed during early and late subjective night, respectively, and no phase shifts were obtained during midsubjective day. Maximum phase delays of 2.2 +/- 0.3 hr were obtained at CT 14, and maximum phase advances of 3.5 +/- 0.2 hr were obtained at CT 20. Phase delays were not blocked by a combination of NMDA [AP-5 (100 microM)] and non-NMDA [CNQX (10 microM)] receptor antagonists or by tetrodotoxin (TTX) at concentrations of 1 or 3 microM. The phase response curve for heat pulses is similar to ones obtained with light pulses for behavioral rhythms. These data demonstrate that circadian pacemaker period in the rat SCN is temperature-compensated over a physiological range of temperatures. Phase delays were not caused by activation of ionotropic glutamate receptors, release of other neurotransmitters, or temperature-dependent increases in metabolism associated with action potentials. Heat pulses may have phase-shifted rhythms by directly altering transcriptional or translational events in SCN pacemaker cells.  (+info)

Biological oscillations with an ultradian time scale of 1 to several hours include cycles in behavioral arousal, episodic glucocorticoid release, and gene expression. Ultradian rhythms are thought to have an extrinsic origin because of a perceived absence of ultradian rhythmicity in vitro and a lack of known molecular ultradian oscillators. We designed a novel, non-spectral-analysis method of separating ultradian from circadian components and applied it to a published gene expression dataset with an ultradian sampling resolution. Ultradian rhythms in mouse hepatocytes in vivo have been published, and we validated our approach using this control by confirming 175 of 323 ultradian genes identified in a prior study and found 862 additional ultradian genes. For the first time, we now report ultradian expression of ,900 genes in vitro. Sixty genes exhibited ultradian transcriptional rhythmicity, both in vivo and in vitro, including 5 genes involved in the cell cycle. Within these 60 genes, we ...

Get this from a library! Ultradian rhythms from molecules to mind : a new vision of life. [David Lloyd; Ernest Lawrence Rossi, 1933-;]
Human sleep episodes are characterized by an approximately 90-min ultradian oscillation between rapid eye movement (REM) and non-REM. (NREM) sleep stages. The source of this oscillation is not known. Pacemaker mechanisms for this rhythm have been proposed, such as a reciprocal interaction network, but these fail to account for documented homeostatic regulation of both sleep stages. Here, two candidate mechanisms are investigated using a simple model that has stable states corresponding to Wake, REM sleep, and NREM sleep. Unlike other models of the ultradian rhythm, this model of sleep dynamics does not include an ultradian pacemaker, nor does it invoke a hypothetical homeostatic process that exists SC75741 price purely to drive ultradian rhythms. Instead, only two inputs are included: the homeostatic drive for Sleep and the circadian drive for Wake. These two inputs have been the basis for the most influential Sleep/Wake models, but have not previously been identified as possible ...
Nonlinear delay-differential equations represent infinite-dimensional systems for which characterising the behaviour of solutions can be technically challenging. Their appearance in many applied fields, such as population biology, is in great part due to their ability to model dynamics with non-instantaneous effects. These phenomena often exhibit behaviour which does not occur in the associated non-delayed counterpart. In particular, it is known that delays can trigger the occurrence of oscillatory behaviour and can, in several cases, bring evidence for mechanisms underlying oscillations in biological systems. Oscillatory dynamics play an important role in the accurate regulation of hormones. Such rhythms in the ultradian regime have been observed in multiple physiological areas such as the HPA-axis, phases of sleep, and the glucose regulatory system.. In this contribution, the effect of diabetic deficiencies on the production of an oscillatory ultradian regime is studied using a deterministic ...
The issue is that there is an assumption that REM sleep is dreaming sleep. Dement and Kleitman woke participants up at the times when their brain waves were characterised by REM sleep. They found that participants were highly likely to report dreaming. However, they also found that participants would dream out of REM sleep and others would not dream with in REM sleep. ...
P300 event-related brain potentials (ERPs) were elicited using a simple discrimination task in which participants discriminated two different equiprobable visual stimuli with button-press responses (n = 20). A total of ten trial blocks were presented at 10-min intervals. P300 amplitude declined significantly, but peak latency did not change reliably across trial blocks. P300 amplitude demonstrated a reliable cyclical fluctuation across trial blocks, although P300 latency did not. Intra-trial block ERP variability was assessed by computing the correlation coefficients between the target and standard stimuli for amplitude and latency measures across participants within each trial block. P300 amplitude correlations were weakest at the Fz electrode, more strongly associated at Cz, and were most strongly correlated at Pz across trial blocks. P300 latency correlations were somewhat weaker and similar in strength across electrodes sites. The correlational patterns for both P300 amplitude and latency ...

AU - Ootsuka, Youichirou. PY - 2016. Y1 - 2016. N2 - Charles Darwin noted that natural selection applies even to the hourly organization of daily life. Indeed, in many species, the day is segmented into active periods when the animal searches for food, and inactive periods when the animal digests and rests. This episodic temporal patterning is conventionally referred to as ultradian (,24 hours) rhythmicity. The average time between ultradian events is approximately 1-2 hours, but the interval is highly variable. The ultradian pattern is stochastic, jaggy rather than smooth, so that although the next event is likely to occur within 1-2 hours, it is not possible to predict the precise timing. When models of circadian timing are applied to the ultradian temporal pattern, the underlying assumption of true periodicity ...
The hypothalamic-pituitary-adrenal (HPA) axis is critical for life. It has a circadian rhythm that anticipates the metabolic, immunoregulatory and cognitive needs of the active portion of the day, and retains an ability to react rapidly to perceived stressful stimuli. The circadian variation in glucocorticoids is very noisy because it is made up from an underlying approximately hourly ultradian rhythm of glucocorticoid pulses, which increase in amplitude at the peak of circadian secretion. We have shown that these pulses emerge as a consequence of the feedforward-feedback relationship between the actions of corticotrophin hormone (ACTH) on the adrenal cortex and of endogenous glucocorticoids on pituitary corticotrophs. The adrenal gland itself has adapted to respond preferentially to a digital signal of ACTH and has its own feedforward-feedback system that effectively amplifies the pulsatile characteristics of the incoming signal. Glucocorticoid receptor signalling in the body is also adapted to

They transduce these environmental rhythms into respective intracellular rhythms of second messengers as well as in regular release of coupling factors such as neuropeptides. The rhythmically released neuropeptides in turn will generate intracellular changes of second messengers in all neuropeptide receptor expressing cells at the time course of the environmental cues. In the animal kingdom highly conserved neuropeptides such as pigment-dispersing factor (PDF) appear to serve similar physiological functions. Activation of neuropeptide receptors is translated into a limited repertoire of second messengers. Among these are nucleotide derivatives like cyclic adenosine monophosphate ...

Thinking about concomitant parameter changes led us to the next candidate explanation. As with the tendency to use a lower TR for SMS-EPI than for regular EPI, there is also a tendency to drive the in-plane gradients harder. Heres the logical progression. We start with a change in the slice dimension whereby SMS permits, say, 2 mm slice thickness and full brain coverage in a TR below 2000 ms. Next, we are tempted to improve the in-plane resolution in order to get cubic voxels. The only way to get finer resolution in-plane is to make the frequency and phase encoding gradients work harder. The SMS scheme doesnt help (or hinder very much - see Note 2) the in-plane dimension, however, and theres only so much one can drive the gradients before the total gradient area must be increased through longer application times.

What do these results suggest?. There is something fishy about the reindeer clock. It is not working the same way it does in other mammals studied to date. For example, seals and humans living in the Arctic have normal circadian rhythms of melatonin. Some other animals show daily rhythms in behavior. But in reindeer, rhythms in behavior and melatonin can be seen only if the environment is rhythmic as well. In constant light conditions, it appears that the clock is not working. But, is it? How do we know?. During the long winter night and the long summer day, the behavior of reindeer is not completely random. It is in bouts which show some regularity - these are ultradian rhythms with the period much shorter than 24 hours. If the clock is not working in reindeer, i.e., if there is no clock in this species, then the ultradian rhythms would persist during spring and fall as well. Yet we see circadian rhythms during these seasons - there is an underlying clock there which can be entrained to a ...

Studies on glucocorticoid receptor (GR) action typically assess gene responses by long-term stimulation with synthetic hormones. As corticosteroids are released from adrenal glands in a circadian and high-frequency (ultradian) mode, such treatments may not provide an accurate assessment of physiological hormone action. Here we demonstrate that ultradian hormone stimulation induces cyclic GR-mediated transcriptional regulation, or gene pulsing, both in cultured cells and in animal models. Equilibrium receptor-occupancy of regulatory elements precisely tracks the ligand pulses. Nascent RNA transcripts from GR-regulated genes are released in distinct quanta, demonstrating a profound difference between the transcriptional programs induced by ultradian and constant stimulation. Gene pulsing is driven by rapid GR exchange with response elements and by GR recycling through the chaperone machinery, which promotes GR activation and reactivation in response to the ultradian hormone release, thus coupling ...
When you first wake up in the morning, blood pressure (BP) increases due to the bodys normal circadian rhythm. Circadian rhythm is a daily 24-hour activity cycle that affects our sleep/wake patterns. In the morning, the body releases certain hormones such as adrenaline and noradrenaline.
As it turns out, late morning turns out to be the best time to try doing tasks such as mental arithmetic that demand that we hold several pieces of information in mind at once. Later in the afternoon is the time to attempt simpler tasks, like searching for a particular letter in a page of gibberish.. Another clue about the clock in our brains comes from people with conditions such as depression and bipolar disorder. People with these disorders often have trouble sleeping at night, or feel groggy during the day. Some people with dementia experience sundowning, becoming confused or aggressive at the end of the day..

Solar variations have significant influence on the Earths space environment and climate via its magnetic field, irradiation and energetic particles. Long-term and reliable historical datasets of solar and stellar activity indices are crucial for understanding the variations and predicting the future solar cycle. Cosmogenic and radionuclides can extend our knowledge of solar variations back to the Holocene. There are a number of important and hot issues relevant to the evolution of solar activity and variability. These include, how to build up longterm consistent datasets, e.g., sunspot number and solar irradiance, how to realistically reconstruct the physics parameters, e.g., interior convection spectrum and photospheric open flux, based on the records, how to understand the relations among different indices, how to model the solar cycles based on the observed data. Furthermore, the progress in the understanding of the stellar variability and activity cycles helps us to understand the solar ...
Both abnormal automaticity and triggered activity induced by delayed afterdepolarizations have been proposed as the primary mechanism for ventricular tachycardia (VT) occurring in dogs 24 hr after ligation of the left anterior descending coronary artery. Because of this controversy, we studied the effects of ventricular pacing and therapeutic concentrations of lidocaine and ethmozin on sustained rhythmic activity of isolated subendocardial preparations excised from the infarct, and on VT in conscious dogs. There were differences in the sustained rhythmic activity cycle length of isolated preparations and the VT cycle length that were attributable to the absence of sympathetic input in the former and its presence in the latter.

When a coronal mass ejection reaches Earth, it interacts with our planets magnetic field, potentially creating a geomagnetic storm. Solar particles stream down the field lines toward Earths poles. Those particles collide with atoms of nitrogen and oxygen in the atmosphere, which then glow like miniature neon signs. Aurorae normally are visible only at high latitudes. However, during a geomagnetic storm aurorae can light up the sky at lower latitudes. Sky watchers in the northern U.S. and other countries should look toward the north on the evening of August 3rd/4th for rippling curtains of green and red light. The Sun goes through a regular activity cycle about 11 years long on average. The last solar maximum occurred in 2001. Its latest minimum was particularly weak and long lasting. This eruption is one of the first signs that the Sun is waking up and heading toward another maximum. ...

Abnormalities in sleep and circadian rhythms are central features of bipolar disorder (BP), often persisting between episodes. We report here, to our knowledge, the first systematic analysis of circadian rhythm activity in pedigrees segregating severe BP (BP-I). By analyzing actigraphy data obtained from members of 26 Costa Rican and Colombian pedigrees [136 euthymic (i.e., interepisode) BP-I individuals and 422 non-BP-I relatives], we delineated 73 phenotypes, of which 49 demonstrated significant heritability and 13 showed significant trait-like association with BP-I. All BP-I-associated traits related to activity level, with BP-I individuals consistently demonstrating lower activity levels than their non-BP-I relatives. We analyzed all 49 heritable phenotypes using genetic linkage analysis, with special emphasis on phenotypes judged to have the strongest impact on the biology underlying BP. We identified a locus for interdaily stability of activity, at a threshold exceeding genome-wide ...
Activity onsets of horn sharks, Heterodontus francisci, were studied in the natural environment at Santa Catalina Island, California. The mean of activity onsets of these nocturnal sharks occurred 76 min after sunset which corresponded to an approximate light level of 0.03 lux. During laboratory studies under a fixed LD 12:12 (12 hr light- 12 hr dark) regime, the L phase of which was 8 lux, H. francisci showed anticipation of the D phase. Under 23 days of constant dim light, H. francisci exhibited a drifting circadian rhythm with period lengths, for one individual, of 20.8 hr under 2.0 lux, and 23.0 hr under 0.13 lux. Under 15 days of constant darkness, the sharks showed a high level of aperiodic activity. During laboratory experimental dusk transitions, the light intensity eliciting onset of activity was: 1), proportional to the amount of time sharks spent in the L phase of the LD regime, and 2), independent of the level of Hght duiing the L phase of the LD regime.
Mammalian skeletal muscle is influenced by the functional demands placed upon it. Functional morphology of facial expression musculature, or mimetic musculature, is largely unknown. Recently, primate mimetic musculature has been shown to respond to demands associated with social factors. Body size has also been demonstrated to affect many aspects of primate functional morphology and evolutionary morphology. The present study was designed to further examine the role of social variables and body size in influencing the morphology of primate mimetic musculature using a broad phylogenetic range of primates, primates with varying body sizes, and those that exploit differing time of day activity cycles and social group sizes ...

Organisms go through cycles of metabolic activity, driven by internal cues (circadian, circannual clocks) and physiologic/behavioral inputs (e.g. feeding/fasting, physical activity/rest). In addition, organisms face environmental challenges (physical, chemical or psychological stressors) that require continual adaptation of the pathways regulating metabolism. The goal of our research is to elucidate the regulatory and transcriptional mechanisms that integrate information and enable physiologic adaptations (particularly in response to changes in physical activity, environmental temperature, nutritional state), and that, when deregulated, contribute to metabolic disease. Our studies focus on the Estrogen-Related Receptors (ERRα, ERRβ, and ERRγ), which we use as an entry point to the study of the regulatory / transcriptional networks that are important for adaptation in adipose tissue and in skeletal muscle, in response to changes in environmental temperature, physical exercise and/or diet. In ...

The Delta Wave Havening Techniques from my extensive clinical experience are the most powerful psychological treatment in the world today for two reasons.
NADH oxidases at the external surface of plant and animal cells (ECTO-NOX proteins) exhibit stable and recurring patterns of oscillations with potentially clock-related, entrainable, and temperature-compensated period lengths of 24 min. To determine if ECTO-NOX proteins might represent the ultradian time keepers (pacemakers) of the biological clock, COS cells were transfected with cDNAs encoding tNOX proteins having a period length of 22 min or with C575A or C558A cysteine to alanine replacements having period lengths of 36 or 42 min. Here we demonstrate that such transfectants exhibited 22, 36, or 40 to 42 h circadian patterns in the activity of glyceraldehyde-3-phosphate dehydrogenase, a common clock-regulated protein, in addition to the endogenous 24 h circadian period length. The fact that the expression of a single oscillatory ECTO-NOX protein determines the period length of a circadian biochemical marker (60 X the ECTO-NOX period length) provides compelling evidence that ECTO-NOX proteins ...

Over the last few days Ive discovered the new iPhone app Sleep Cycle Alarm Clock. This is a really clever app which uses the accelerometer in your iPhone to monitor your movement while you sleep. From the amount you fidget, the app can work out which sleep cycle you are in - awake, light sleep/dreaming, or deep sleep. It then wakes you up when you are in your lightest sleep cycle (within half an hour of your alarm time) so you awake feeling relaxed and refreshed. ...
The hop (Humulus lupulus), a component of beer, is a sedative plant whose pharmacological activity is due principally to its bitter resins, especially to the α-acid component 2-methyl-3-buten-2-ol. The mechanism of action of the resin of hop consists of increasing the activity of the neurotransmitter γ-aminobutyric (GABA), inhibiting the central nervous system (CNS). Objectives: To analyze in an experimental model of diurnal animal the sedative effect of hop, a component of beer, on the activity/rest rhythm. Methods: Experiments were performed with common quail (Coturnix coturnix) similar to humans in the sleep-wake rhythm, isolated in 25 × 25 × 25 cm methacrylate cages, with food and water ad libitum, in a room with artificial ventilation (22 ± 1 °C) and a lighting cycle of 12L/12D (n = 5). The doses administered, close to the content of non-alcoholic beer, were 1, 2 and 11 mg extract of hop as one capsule per day, at 18:00 h for one week. A control group received capsules only with a ...

Tight can also refer to music. You know like sometimes rhythm can be loose (like jazz) and sometimes it can be tight. So if a band that is not a jazz band is playing well, someone might say they are tight so that could be another reason why tight is good. Back in the 40s, tight meant drunk, which I never understood. Youd think drunk would be loose, but in old movies, people say tight to mean drunk.. ReplyDelete ...

  • Our star is now at " solar maximum ," the peak phase of its 11-year activity cycle. (space.com)
  • But this solar max is weak, and the overall current cycle, known as Solar Cycle 24, conjures up comparisons to the famously feeble Solar Cycle 14 in the early 1900s, researchers said. (space.com)
  • But such effects have rarely been seen during Solar Cycle 24, even though the total number of CMEs hasn't dropped off much, if at all. (space.com)
  • This lower pressure has allowed CMEs to expand greatly as they cruise through space, said Nat Gopalswamy of NASA's Goddard Space Flight Center in Greenbelt, Md. Indeed, Solar Cycle 24 CMEs are, on average, 38 percent bigger than those measured during the last cycle - a difference with real consequences for folks here on Earth. (space.com)
  • Scientists also think they know why relatively few super-fast solar energetic particles, or SEPS, have been measured in Earth's neighborhood during the current cycle, which began in early 2008. (space.com)
  • It has to do with a weakened interplanetary magnetic field, another characteristic of Solar Cycle 24, they say. (space.com)
  • The strength or weakness of a solar cycle appears to be driven by the intensity of the sun's polar magnetic field during the previous cycle. (space.com)
  • The polar field is thought to feed the sunspots - dark and relatively cool patches on the sun that are the source of CMEs and solar flares - that come in during the next cycle, Gopalswamy said. (space.com)
