The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation.

One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed.

Effect of pH and monovalent cations on the formation of quinonoid intermediates of the tryptophan synthase alpha(2)beta(2) complex in solution and in the crystal. (1/16)

Quinonoid intermediates play a key role in the catalytic mechanism of pyridoxal 5'-phosphate-dependent enzymes. Whereas the structures of other pyridoxal 5'-phosphate-bound intermediates have been determined, the structure of a quinonoid species has not yet been reported. Here, we investigate factors controlling the accumulation and stability of quinonoids formed at the beta-active site of tryptophan synthase both in solution and the crystal. The quinonoids were obtained by reacting the alpha-aminoacrylate Schiff base with different nucleophiles, focusing mainly on the substrate analogs indoline and beta-mercaptoethanol. In solution, both monovalent cations (Cs(+) or Na(+)) and alkaline pH increase the apparent affinity of indoline and favor accumulation of the indoline quinonoid. A similar pH dependence is observed when beta-mercaptoethanol is used. As indoline and beta-mercaptoethanol exhibit very distinct ionization properties, this finding suggests that nucleophile binding and quinonoid stability are controlled by some ionizable protein residue(s). In the crystal, alkaline pH favors formation of the indoline quinonoid as in solution, but the effect of cations is markedly different. In the absence of monovalent metal ions the quinonoid species accumulates substantially, whereas in the presence of sodium ions the accumulation is modest, unless alpha-subunit ligands are also present. Alpha-subunit ligands not only favor the formation of the intermediate, but also reduce significantly its decay rate. These findings define experimental conditions suitable for the stabilization of the quinonoid species in the crystal, a critical prerequisite for the determination of the three-dimensional structure of this intermediate.  (+info)

Staphylococcal exfoliative toxins cleave alpha- and beta-melanocyte-stimulating hormones. (2/16)

The staphylococcal exfoliative toxins (ETs) A and B (ETA and ETB) are 27-kDa exotoxins produced by certain strains of Staphylococcus aureus and are the causative agents of staphylococcal scalded-skin syndrome. The crystal structures of the ETs strongly indicate that the proteins are members of the serine protease family of enzymes, although protease activity until now has not yet been conclusively demonstrated. Here, we show that the peptide beta-melanocyte-stimulating hormone (beta-MSH) is cleaved by ETA and that both ETA and ETB are capable of cleaving alpha-MSH. Both toxins exhibit cleavage at specific glutamic acid residues in MSH peptides. Moreover, biologically inactive mutants of ETA were incapable of cleaving beta-MSH.  (+info)

Doxorubicin impairs crossbridge turnover kinetics in skinned cardiac trabeculae after acute and chronic treatment. (3/16)

Crossbridge dynamics underlying the acute and chronic inotropic effects of doxorubicin (Dox) were studied by application of releasing length steps (amplitude, 0.5-10%) to skinned cardiac trabeculae. Acute incubation of trabeculae with 20 microM Dox for 30 min resulted in a decrease of the velocity of unloaded shortening (V(0), from 9.3 +/- 1.1 to 7.7 +/- 0.7 microm/s, P <.05) and in an increase of the rate of force redevelopment (tau(r), from 56 +/- 4 to 65 +/- 3 ms, P <.05) in response to step amplitudes ranging from 5 to 10%. In contrast, chronic Dox treatment in rats (2 mg/kg/week for 4 weeks) significantly impaired trabecular crossbridge dynamics after step releases of 0.5%. This was reflected by an increase of all time constants describing tension recovery: tau(1), from 10 +/- 1 to 14 +/- 1 ms; tau(2), from 65 +/- 6 to 82 +/- 6 ms; tau(3), from 92 +/- 7 to 293 +/- 67 ms; P <.05. In addition, V(0) was decreased (from 8.6 +/- 0.6 to 6.8 +/- 0.3 microm/s, P <.05) and tau(r) was increased (from 67 +/- 4 to 89 +/- 3 ms; P <.05) in the slack-test. We found that chronic Dox treatment resulted in a shift from the "high ATPase" alpha-myosin heavy chain (MHC) isoform toward the "low-ATPase" beta-MHC isoform in the ventricles (control: alpha-MHC 79 +/- 2% and beta-MHC 21 +/- 2%; Dox-treated: alpha-MHC 53 +/- 2% and beta-MHC 47 +/- 2%; P <.05). The present results show that acute Dox incubation affects the detachment rate of crossbridges, which leads to a delayed relaxation and an arrest of crossbridges in strongly bound states. In contrast, chronic Dox treatment leads to an impairment of both the attachment and detachment rates in the crossbridge cycle, which may be explained by an altered MHC isoform composition in ventricular myocardium. Interfering with Dox-induced alterations of crossbridge kinetics may provide a new strategy to prevent Dox-associated cardiotoxicity.  (+info)

A missense mutation disrupting a dibasic prohormone processing site in pro-opiomelanocortin (POMC) increases susceptibility to early-onset obesity through a novel molecular mechanism. (4/16)

The functional loss of both alleles of the human pro-opiomelanocortin (POMC) gene leads to a very rare syndrome of hypoadrenalism, red hair and early-onset obesity. In order to examine whether more subtle genetic variants in POMC might contribute to early-onset obesity, the coding region of the gene was sequenced in 262 Caucasian subjects with a history of severe obesity from childhood. Two children were found to be heterozygous for a missense mutation, R236G, which disrupts the dibasic cleavage site between beta melanocyte-stimulating hormone (beta-MSH) and beta-endorphin. Beta-TC3 cells transfected with the mutant POMC cDNA produced a mutant beta-MSH/beta-endorphin fusion protein. This fusion protein bound to the human melanocortin-4 receptor (hMC4R) with an affinity similar to its natural ligands, but had a markedly reduced ability to activate the receptor. This variant co-segregated with early-onset obesity over three generations in one family and was absent in 412 normal weight UK Caucasian controls. Combining the results in UK Caucasians with a new case-control study in French subjects and three previously published reports, mutations disrupting this processing site were present in 0.88% of subjects with early-onset obesity and 0.22% of normal-weight controls. These results suggest that the R236G mutation may confer an inherited susceptibility to obesity through the production of an aberrant fusion protein that has the capacity to interfere with central melanocortin signalling.  (+info)

Detection and characterization of methionine oxidation in peptides by collision-induced dissociation and electron capture dissociation. (5/16)

Electron capture dissociation (ECD) and collision-induced dissociation (CID), the two complementary fragmentation techniques, are demonstrated to be effective in the detection and localization of the methionine sulfoxide [Met(O)] residues in peptides using Fourier transform ion cyclotron resonance (FTICR) mass spectrometry. The presence of Met(O) can be easily recognized in the low-energy CID spectrum showing the characteristic loss of methanesulfenic acid (CH(3)SOH, 64 Da) from the side chain of Met(O). The position of Met(O) can then be localized by ECD which is capable of providing extensive peptide backbone fragmentation without detaching the labile Met(O) side chain. We studied CID and ECD of several Met(O)-containing peptides that included the 44-residue human growth hormone-releasing factor (GRF) and the human atrial natriuretic peptide (ANP). The distinction and complementarity of the two fragmentation techniques were particularly remarkable in their effects on ANP, a disulfide bond-containing peptide. While the predominant fragmentation pathway in CID of ANP was the loss of CH(3)SOH (64 Da) from the molecular ion, ECD of ANP resulted in many sequence-informative products, including those from cleavages within the disulfide-bonded cyclic structure, to allow for the direct localization of Met(O) without the typical procedures for disulfide bond reduction followed by [bond]SH alkylation.  (+info)

A novel mechanism in control of human pigmentation by {beta}-melanocyte-stimulating hormone and 7-tetrahydrobiopterin. (6/16)

The human skin holds the full machinery for pro-opiomelanocortin processing. The alpha-melanocyte-stimulating hormone (alpha-MSH)/melanocortin-1-receptor cascade has been implicated as a major player via the cAMP signal in the control of melanogenesis. Only very recently the beta-endorphin/mu-opiate receptor signal has been added to the list of regulators of melanocyte dendricity and melanin formation. In this context it was reported that (6R)-l-erythro-5,6,7,8-tetrahydrobiopterin (6BH(4)) can act as an allosteric inhibitor of tyrosinase, the key enzyme in melanogenesis, and this inhibition is reversible by both alpha- and beta-MSH. It was also shown earlier that 7BH(4), the isomer of 6BH(4), is twice as active in this inhibition reaction. However, as yet it is not known whether 7BH(4) is indeed present in loco in the melanosome. We here provide evidence that this isomer is present in this organelle in a concentration range up to 50 x 10(-6) M. Determination of beta-MSH in melanosomal extracts yielded 10 pg/mg protein. Moreover, we demonstrate reactivation of the 7BH(4)/tyrosinase inhibitor complex by beta-MSH, whereas alpha-MSH failed to do so. Furthermore, we show intra-melanosomal l-dopa formation from dopachrome by 7BH(4) in a concentration range up to 134 x 10(-6) M. Based on these results, we propose a new receptor-independent mechanism in the control of tyrosinase/melanogenesis by beta-MSH and the pterin 7BH(4).  (+info)

The molecular genetics of the melanocortin pathway and energy homeostasis. (7/16)

The CNS melanocortin pathway plays an important role in the control of body weight. Two papers in this issue of Cell Metabolism, Lee et al., 2006 and Biebermann et al., 2006, suggest that beta MSH--a product of POMC processing--plays an unanticipated role in this pathway in humans.  (+info)

A POMC variant implicates beta-melanocyte-stimulating hormone in the control of human energy balance. (8/16)

The melanocortin-4 receptor (MC4R) plays a critical role in the control of energy balance. Of its two pro-opiomelanocortin (POMC)-derived ligands, alpha- and beta-MSH, the majority of attention has focused on alpha-MSH, partly reflecting the absence of beta-MSH in rodents. We screened the POMC gene in 538 patients with severe, early-onset obesity and identified five unrelated probands who were heterozygous for a rare missense variant in the region encoding beta-MSH, Tyr221Cys. This frequency was significantly increased (p < 0.001) compared to the general UK Caucasian population and the variant cosegregated with obesity/overweight in affected family members. Compared to wild-type beta-MSH, the variant peptide was impaired in its ability to bind to and activate signaling from the MC4R. Obese children carrying the Tyr221Cys variant were hyperphagic and showed increased linear growth, both of which are features of MC4R deficiency. These studies support a role for beta-MSH in the control of human energy homeostasis.  (+info)

The pituitary gland lies in between the two halves of the brain at the base of the third vertebrae. In scientific terms, it is known as the master gland because it regulates and controls the rate at which the other glands release their hormones and the timing of the release. Until the pineal gland tells the body to act, it doesnt act.. The pituitary gland is divided into three lobes. The anterior lobe is in charge of regulating the activity of the thyroid gland, the adrenal glands, and the gonads. It tells the body when to grow, how much to grow, and when to stop growing. It also regulates the production of breast milk by pregnant and nursing mothers so that they can nourish the growth of their young. The intermediate lobe dictates the pigmentation of skin, releasing more Beta-melanocyte-stimulating hormone when theres been increased exposure to direct sunlight and more protection is needed and decreasing the levels when theres less sunlight so that more of sunlight can be taken in and ...

Its long been my feeling that no one, but no one, should have a job, by which I mean something not personally meaningful that we crimp our wild and precious lives into doing for hours and hours each day - just to make a living, just for the money. This jobs shibboleth is, of course, one of the cornerstones of the wage-slave Old World Order now crumbling under the weight of rising unemployment worldwide.. What would happen if instead of looking for a job we all started doing what we love, and sharing that with one another? We tend to think of money as the bottom line. But what if it is not? What if, instead, human energy is the bottom line, and money energy is merely an abstract, agreed-upon transposition of this ancient and fundamental bottom line?. If we think of money as energy fueling the circulatory system of the so-called civilized world; and if we think of a unit of money as, ultimately, the transposition of a bottom-line unit of human energy, then time banks are ways of ...

Technology is constantly evolving and changing, sometimes faster than you could ever guess. These new tools can make businesses more productive, secure and agile. However, these tools need the right network to support them.. Structured cabling is an infrastructure thats made up of smaller, standardized elements. You can install structured cabling systems in a building or across a campus. Its this kind of network cabling that can support all of the rapidly-advancing technology coming to the workplace.. Since the advent of personal computers, the introduction of laptops and VoIP calling systems, the demand on a businesss cable network has only grown. In the past, point-to-point cabling was used, which meant every piece of hardware used its own cable. The cabling literally ran from point to point. This would lead to a jumbled mess of wiring and cables that could be accidentally unplugged or present a safety hazard for tripping. To accommodate the rising need for speed and more bandwidth, ...
Why variants?==== A problem with boost and all this signal/slot stuff is if you want to send variables you have to know in advance what variables should be passed. We get around that by using Variant and VariantList. ====Variant==== Variant is a special kind of variable that can be a number, a string, a vector3, or a pointer to an entity or component. (Its pretty easy to add support for more data types btw) Example: ,code cpp, Variant v; //so far it doesnt know what it is LogMsg(V is %s, v.Print().c_str()); //output: V is Unknown v.Set(uint32(10)); LogMsg(V is %s. Or, in number form: %d, v.Print().c_str(), v.GetUINT32()); //output: V is 10. Or, in number form: 10 //what if we try to access it wrong? float f = v.GetFloat(); //it will assert and tell you its a uint32, not a float ,/code, So if you see a function that expects a Variant type, you can call it like this: ,code cpp, SomeFunc(Variant(Hello! Hope you wanted a string!)); //or SomeFunc(1.0f); ,/code, If the compiler isnt sure if ...

In summary, we were not able to detect a consistent association with obesity or diabetes phenotypes for either the K121Q minor allele or the risk haplotype Q-delT-G in large cohorts. Our results, those in the accompanying article by Weedon et al. (20), a recent Japanese study (21), and the conflicting data in the previous literature (5-8) (with some evidence for both the Q-allele and the K-allele being risk alleles) suggest that the previously reported associations to ENPP1 may represent false positives or associations that are not easily generalizable. Our investigations are not an exact replication of the previously reported studies due to different ascertainment designs. However, we have successfully reproduced other associations with diabetes (KCNJ11 [22,23], PPARG [10], and TCF7L2 [24]) and obesity (INSIG2 [25]) using these samples. In contrast to Meyre et al. (6), we did not test for association in children, possibly missing an effect specific to severe or early-onset obesity.. Our failure ...

Plants use biological systems that harvest light energy from the sun to convert environmental water and carbon dioxide into tiny carbon/hydrogen energy units stored within them. When people eat those energy units, the extraordinary human digestive and metabolic systems convert the work of plants into energy that is useful to people and give back water and carbon dioxide to the environment that can be used by plants. How do these systems make that happen? Journey to the Stomach Ingested food encounters precisely-shaped teeth that cut and grind it into small pieces--which, surprisingly, is the second step of the digestion process. The first vital step involves the brain readying the digestive organs for an influx of food. When the brains association areas match smells, sights, and even sounds of food with imprinted memories of eating, the nervous system signals the process to start. Glands in the mouth respond by secreting saliva, which is mostly water, but also contains digestive enzymes, ...
Surgical treatment of obesity is as effective for individuals who developed the disorder early, by the age of 20, as for those who have developed obesity later in life, a study from the University of Gothenburg shows.
The process of releasing traumas through this exercise is interesting. It gently brings the mind to a peaceful place where you can view old incidents and traumas from a detached perspective, almost as if they happened to someone else. In this way, you can avoid much of the fear and anxiety that occur when old traumas are brought up to consciousness.. Also, old traumas, if they come up, will be brought up in a special order that is not your own. Instead, it is the body s own order of trauma release. This is also important because many people think they know the correct order in which traumas should surface. In fact, we do not know the correct order because the brain is complex and the proper order of trauma release can be very subtle.. For example, incidents that you don t even consider traumatic may have been quite so. Conversely, situation that you consider pivotal for you may really have been due to an earlier situation. You may have forgotten the earlier trauma that set you up for later ...
We stand at the threshold of a time of compelling change-a positive major shift is taking place, and that shift is having a dramatic impact on our lives. We are compelled to talk about it and to seek to understand it. It is awakening a new energy force within each of us that is causing dynamic change to occur within the physical body and the human energy system. We are changing to forms of light that are not as we have previously known them, and are becoming more vibrant, more radiant, and more empowered. This new energy force is changing our way of thinking and is illuminating a whole new dimension of our persona. It is creating the need for intense self-exploration and we are being nudged, pushed, and driven to learn more about who we really are. It is fueling the desire to better understand ourselves-its energy is assisting us in seeking to get in touch with our very souls. We are being guided to look beyond the obvious and that which our five senses understand. This new energy force is ...

Objective i - The first phase of the proposed work (Phase I) will involve two laboratory-based examinations of the acute metabolic and behavioural responses to extended fasting relative to ingestion of a standardised breakfast. These trials will be applied in a randomised and counterbalanced order with 3-28 days interval except for eumenorrheic women, whose trials will be separated by 28 ± 2 days and only at least 3 and at most 10 days after the onset of menses (i.e. follicular phase) to ensure that the effects of menstrual cycle on the majority of hormones and therefore resting metabolic rate (RMR) and appetite will be both minimal and standardised between trials [69-71]. These acute trials will be conducted in our resting metabolism laboratory in accordance with current guidelines for best practice in measuring resting metabolic rate [72]. Most notably, ambient temperature in this laboratory is maintained between 20 and 25°C (with intra-individual trials standardised within 2°C) and ...

On August 28th the first of the two exact Eris Pluto squares will be taking place. In terms of Astrology, Pluto is being seen as a gatekeeper and escort into deeper levels of self-empowerment. It emphasizes the importance of looking within the self, rather than outside of self, and finding our nuclear core of the creative force. It also emphasizes the use of that force in ways that empower others and that awaken ourselves to new vistas of human potential, conscious awareness, and experience waiting to be realized. Eris is a feminine warrior archetype that has no fear or hesitation to intervene and expose a greater hidden truth. She tends to pierce or crack open our current bubble of perception through which we view and experience the world to see beyond the finite bounds of our current perception, beyond the bounds we place upon ourselves. In other words, it helps us to unlearned what we learned incorrectly in the past. On that day, many protests against coronavirus restrictions are sc ...

The c.1588T,C (p.Tyr530His) missense variant in the SLC26A4 gene has been reported as a common deleterious variant associated with Pendred Syndrome (Coyle et al., 1998; Blons et al., 2004). This variant has been reported in several affected individuals, often in trans with a second deleterious variant (V138F, T410M, c.2089+1G,A, V422D, T416P, Y78C, F355S) (Blons et al., 2004; Banghova et al., 2008; Borck et al., 2009; Ladsous et al., 2014). Functional studies have shown this variant affects protein localization within the cell; additionally, some affected individuals harboring this variant have elevated thyroglobulin (Choi et al., 2009; Ladsous et al., 2014). This variant is reported at low frequency within the control population databases (Exome Sequencing Project [ESP] = NA; 1000 Genomes = NA; and ExAC = 0.002). Multiple in silico algorithms predict the variant to have a deleterious effect (GERP = 5.96; CADD = 26.2; PolyPhen = 1; SIFT = 0.02). In addition, reputable diagnostic laboratories ...
by Julia M. Grassinger,Sophie Merz,Heike Aupperle-Lellbach,Hanna Erhard and Robert Klopfleisch Vet. Sci. 2019, 6(1), 31; Published: 19 March 2019 Abstract The presence of BRAF variant V595E, as well as an increased cyclooxygenase-2 (COX-2) expression in canine transitional cell carcinoma (TCC) are well-described in the literature. The aim of the present study was to investigate the correlation between breed (terrier versus non-terrier dogs), histological grade, COX-2 expression, and BRAF mutation in canine TCC. Therefore, transmural TCC biopsies from 65 dogs (15 terriers, 50 non-terriers) were graded histologically into low- and high-grade. Immunohistochemical evaluation of the intensity of COX-2 expression was performed using an immunoreactive score (IRS). Exon 15 of chromosome 16 was examined for the BRAF variant c.1799T,A by TaqMan® SNP assay. TCC was low-grade in 20 cases (one terrier, 19 ...

Chinese Image Medicine is the holistic (integral) medicine which performs the complex diagnostics and treatment of a man at all his fundamental ontological levels at once: physical, energy, informational and heart-spiritual (psychical, mental), considering their indissoluble intercommunication and influence of natural and social mans environment.. Chinese Image Medicine focuses on activation of self energy and self informational resources of human organism and on mobilization of the heart-mentally-spiritual dimensions as important factors of recovery and healthy way of life.. The basic method of diagnostics in CIM is the method of internal vision of the disease images, that determines causal, symptomatic diagnostics of the patients state, namely, identification of his physical, energy, informational and heart-spiritual problems. As auxiliary diagnostic methods are used energy diagnostics, that determines deviations inside the human energy system and explains the symptoms related to imbalance ...
Overall I agree with your and Fintans assessments. There is not one organization or group ruling the world except for the coalescing interests of the haves against the have-nots. What the true issue always comes down to is the moral or ethical degree in which these individuals conduct themselves. We are obviously at a crossroads in human sensibility and these haves have brainwashed people into believing that if we grab and grab (Stab others in the back to get ahead) our way to success without caring about repercussions which are put upon our fellow human beings we will become a society in decline (I guess you may even consider this Mercantilist in nature). I do believe this is happening already but just like any universal content our human energy/ability/love will not be lost. I cannot believe that if energy is never lost then we as a part of this grand system will allow ourselves to be lost. We always hear about dying civilizations of the past but has anyone stopped and thought that these ...

Copenhageners on bicycles are clearly visible to everyone, especially to each other, and their melody is much more symphonic. There is human energy on display. There are visible faces and assorted postures to regard. As homo sapiens we search for recognisable signals from faces and body language. A long line of cars gives us little we can identify with. Psychology has taught us that we humans despise creatures like spiders and insects because we cannot identify with them because they lack a human face, whereas we love dogs and monkeys and other creatures with faces resembling our own ...
In the private sector, platforms like Yelp,, and Kickstarter are giving increasing power to consumers. These tools create an ongoing process of suggestion and response-a feedback loop-- that motivates companies to listen to consumers and to create new and better products.. But why havent feedback loops given people more power in how they are governed, how donor money is spent, and how social services are delivered? People best understand the issues that affect them and what support they need to solve those problems, but many institutions struggle to understand and respond to their perspective. In many places, power imbalances and cultural practices discourage people from giving feedback at all. As a result, trillions of donor dollars and incredible human energy have been spent with good intentions on social projects, while many of the worlds most dire problems remain unsolved.. We want to promote what works and learn from what doesnt. We want to learn more about how feedback ...
The failure of obesity treatments to sustain weight reduction is widely recognized. The central hypotheses of these studies are that: 1.) Energy and neuroendocrine homeostastic systems are altered during the maintenance of a reduced body weight in a manner that favors weight regain; 2.) These changes occur because weight-reduced individuals are in a state of relative leptin deficiency due to loss of body fat; and 3.) Therefore these changes accompanying the maintenance of a reduced body weight will be reversed if circulating leptin concentrations are restored to those that were present prior to weight reduction.. Maintenance of a reduced body weight is associated with integrated autonomic and neuroendocrine changes that reduce energy expenditure and increase food intake in a manner that is similar to that seen in rodents and humans who are deficient in, or resistant to, the adipocyte-derived hormone leptin. Systemic leptin administration to leptin-deficient rodents and humans reverses the ...
I went to my neurologist today. Ive been having some trouble with my injections, getting an immediate post injection reaction, my heart races, my face flushes, my chest feels tight, and I get nauseous. This lasts at least an hour, and it happens every time I give myself an injection of my MS medication. I brought this up to my doctor today. He suggested taking some Tylenol 30 minutes prior to giving myself the injection.. So, when I got home I had something to eat, and took 2 acetaminophen arthritis, because it was the only kind I could find other than PM. I did not read the label, and I should have. Had I read it, I would have seen that each pill was 650mg of acetaminophen. Essentially I took 1300mg of acetaminophen. Well, the doctor was right, it helped the IPI, but a couple hours later, I laid down to take a nap, and I started feeling a cramping, like I had my period. But I had just finished a week ago, so I knew it wasnt that. I wound up with awful diarrhea and vomiting (TMI, sorry), and I ...

Until the understanding of the principle of weight loss you must first know the concept of obesity and overweight; where it is known that overweight condition in which the body weight above a certain scale for height, Obesity is defined: as the accumulation of fat in the body to the point of conflict with health.. To maintain a healthy weight, must be on the human energy intake balance in The 2 Week Diet Plan with energy by the body to consume daily for life, there are many reasons for obesity and weight gain, but the bug gets in the body of a healthy person weight when they disrupted this equation, when more than the amount of energy ( calorie) intake in the diet for energy (calories) consumed, or when the energy consumed goes down for the intake you get an increase in the weight gradually, according to the extent of the difference between them. A common way to assess weight using the body mass index, which is calculated from the following equation: body weight in kilograms / height in meters ...
Atomically, everything in the Universe is made up of energy and has an aura. An aura is a subtle energy field around any inanimate object or living thing that is made up of atoms. Humans are more complex then inanimate objects therefore our energy field is larger and more complex. The aura of a human body is also referred to as the Human Energy Field (HEF) or biofield in scientific communities. The energy field encompasses our body in an oval or orb like shape, can extend 4 feet or more from our physical body, and is made up of layers. The layers of this field move in and out from the physical body receiving, assimilating, and transmitting information just as our 7 major chakras do. Each layer of the biofield has successively less density and vibrational frequency. Each of the 7 major chakras are connected to each of the layers of our energy field creating an interconnected matrix of energy. The chakras drive the expansion or contraction of our energy field. When our life force energy feels low ...
Energy, metabolism and entropy. Will refer to all types of biological energy transformation as metabolism which are used towards physical work as well as for refueling, growth, reproduction and maintenance. The vast majority of human energy has been put towards forming collectives such as cities and companies as well as to the discovery and implementation of ideas. However, without a steady supply of energy none of this growth or innovation is possible. Energy is primary to everything we do and everything that happens around us and is often underapprecaited by scientists and researchers in most fields. As there is no free lunch regarding energy, every action and energy usage has a consequence in the form of useless energy in the form of heat or disorder, otherwise known as entropy. Entropy, the second law of thermodynamics, always increases and hangs over everyone and everything. Growth stops because of the mismatch between energy demand and supply. However, things which grow super linearly, ...
Food for thought - The Good, The Bad, and The Ugly. From Scientific America. The word energy usually brings to mind barrels of oil, an electrical outlet, or perhaps a wind turbine. But take a look in your fridge; it is full of energy sources! Although our energy source (plant derived biological molecules) has not changed much since… we started eating, there have been revolutionary changes in how we procure food. While human energy was initially what drove the procurement of food (hunting and gathering, early agriculture and husbandry), we are now increasingly dependent on fossil energy sources to do the grueling labor of growing, harvesting, and distributing our food. This shift to more energy intensive agriculture implies a series of tradeoffs, which are best, characterized as The Good, The Bad, and The Ugly. The Good is the many benefits we as a society have reaped from the modern food system including cheaper food in terms of time, economic, and resource inputs. The negative environmental ...
The Benefits of Longjack Attention All Athletes: Longjacks Physical Advantage. As if increasing testosterone werent enough, using Longjack extract also greatly increases ATP production. ATP, or adenosine triphosphate, is the basic unit of energy in the body, responsible for keeping us alive and going. By increasing ATP, overall energy and vitality are increased. Most people want more energy, and Longjack provides it, without hyperstimulation, jittery nerves, or insomnia. This is the holy grail of human energy production, and is a valuable enough health benefit by itself to make Longjack an enduring Ayurvedic superstar regarding natural plant extracts. Athletes and body builders will employ any agent which boosts performance or muscle mass. In both animals and humans, Longjack extract increases muscle mass. In a study of men [1], half of the subjects ingested Longjack extract and half did not. In an eight week physical training program, the men who consumed Longjack extract experienced greater ...
I educated myself last night by watching some videos, one was on the hidden energy work built in to the layout of Long Beach architecture/city planning by the masons. Apparently it collects energy, and not just earthly but human energy, and focuses it for an adept to be able to use. This person who is making the video seems nice. Kind of curious and interested in the occult and the use of unseen power that the descendants from Egypt knew--such as found with the masonic order. He also aligns strongly with music and JZ. I watched the whole hour plus...because he pointed out the structures, I saw he was right, and I wondered what the conclusion was going to be? There was a part where an entity asked him to create a time portal with sound and his computer and a flashlight. He didnt want to be interrupted. He locked himself in his room, and the whole building started to shake. His roommate started cursing and asked him to stop and banged on the door. He didnt. He passed out (went to sleep at ten ...

We see the first known examples of the cultural systems we use and also a zone where they merge into something else. - Andrew Duncan. David Ashfords book takes us into a realisation that these beings called Orcs might be a symptom of how history has been taken away from us, in other words that it cant be written except with the aid of imaginary beings of this type… Ashfords prose, which is also poetry, is a probe into the particular (human) energies that animate these non-humans and in the process radically interferes with the language of Tolkiens nasty anti-modernism, getting help from Blake, Benjamin and others. Of course Orcs are mainstream popular, given their presence ...
I agree. Trumps heart is in the right place on this (rare, I know), but his brains (what little he has) are not. We dont need cognitive elitists. We dont need any (non-European) immigrants at all. ZERO. I agree: better dumb peons than immigrants who will be at the top of the human energy pyramid, elites displacing Whites from professional/technical positions, aliens who will become the new Jews using their high IQs to manipulate American politics to their own selfish racial benefit. We dont need to wreck the middle class, and Trump doesnt need to placate groups that didnt vote for him. And despite the sweaty fantasies of my detractors, I also agree with Spencer that the 1924 Reed-Johnson Act was a good thing (albeit flawed in that it didnt optimally control immigration from the Western hemisphere). I think Spencer is wrong in assuming the massaged IQ data from China, reflecting coastal elites, is reflective of the nation as a whole, including the masses of teeming peasants, but ...

While the structure of oxytocin is highly conserved in placental mammals, a novel structure of oxytocin was recently reported in marmosets, tamarins, and other new world primates. Genomic sequencing of the gene for oxytocin revealed a single in-frame mutation (thymine for cytosine) which results in a single amino acid substitution at the 8-position (proline for leucine).[117] Since this original Lee et al. paper, two other laboratories have confirmed Pro8-OT and documented additional oxytocin structural variants in ...

  • In the fetal porcine pituitary ACTH, .beta. (
  • A gene on chromosome 2p23 that encodes proopiomelanocortin, the melanocortin family of hormones, which include alpha-, beta- and gamma-melanocyte stimulating hormone (MSH) and adrenocorticotropic hormone (ACTH). (
  • ACTH consists of 39 amino acids , the first 13 of which (counting from the N-terminus) may be cleaved to form α-melanocyte-stimulating hormone (α-MSH). (
  • After a short period of time, ACTH is cleaved into α- melanocyte-stimulating hormone (α-MSH) and CLIP, a peptide with unknown activity in humans. (
  • This occurs because melanocyte-stimulating hormone (MSH) and ACTH share the same precursor molecule, pro-opiomelanocortin (POMC). (
  • After production in the anterior pituitary gland, POMC gets cleaved into gamma-MSH, ACTH, and beta-lipotropin. (
  • The subunit ACTH undergoes further cleavage to produce alpha-MSH, the most important MSH for skin pigmentation. (
  • Receptor for MSH (alpha, beta and gamma) and ACTH. (
  • ACTH se sastoji od 39 aminokiselina , od kojih se prvih 13 (računajući od N-kraja ) može otcijepiti da bi se formirao α-melanocit-stimulirajući hormon (α-MSH). (
  • POMC, the precursor of ACTH, MSH, and beta-endorphin peptides, is expressed in the pituitary and in two sites in the brain, in the arcuate nucleus of the hypothalamus and the commissural nucleus of the solitary tract of the brain stem. (
  • Little is known regarding the functions of melanocortin (ACTH and MSH) peptides in the brain. (
  • Blood levels of the pituitary hormones adrenocorticotrope hormone (ACTH) and beta-melanocyte stimulating hormone (beta-MSH) are abnormally high. (
  • As a result, there is a shortage of the peptides made from POMC, including ACTH, α-MSH, and β-MSH. (
  • Iz ovog prekursora takođe nastaju i drugi peptidni hormoni: ACTH ( adrenokortikotropni hormon ), α- i γ-MSH ( Melanocit-stimulišući hormon ). (
  • Other melanocyte-stimulating hormones produced by the pituitary and other tissues include alpha-MSH (contained within the ACTH molecule), beta-MSH, and gamma-MSH. (
  • Melanocortin receptors are activated by members of the melanocortin family: alpha-, beta- and gamma-melanocyte stimulating hormone (MSH) and adrenocorticotropic hormone (ACTH). (
  • And the hormones that bind to them have radiated out as well: they're all derived by processing of a common precursor, pro-opiomelanocortin (POMC), and the first big split was the differentiated function of two of those cleavage products into what we would now call adrenocorticotrophic hormone (ACTH) and melanocyte-stimulating hormone (MSH). (
  • It also enhances the ACTH response to IL-1-beta, suggesting it may play a role in the modulation of neuroendocrine response to inflammation. (
  • 1982 gamma MSH, a putative hormone in the N-terminal region of the ACTH/beta-endorphin (beta-EP) precursor protein, was studied by RIA with an antiserum against gamma 3MSH in ACTH-producing mouse pituitary tumor cells, AtT-20/D16v. (
  • Rat median eminence extracts enhanced the release of gamma MSH-like immunoreactivity (gamma MSH-LI) concomitant with ACTH-like immunoreactivity (ACTH-LI) and beta-EP-like immunoreactivity (beta-EP-LI). (
  • Dexamethasone suppressed the release of gamma MSH-LI as well as ACTH-LI and beta-EP-LI. (
  • The 31K gamma MSH coincided with the migration position of 31K ACTH of 31K beta-EP, and 21-23K gamma MSH coincided with the position of 21-23K ACTH on SDS-PAGE. (
  • The 16-17K gamma MSH coincided with the mouse 16K fragment (reported by Eipper and Mains) of ACTH-beta-lipotropin precursor protein in the migration in SDS-PAGE and in immunoreactivity to anti-gamma MSH antiserum. (
  • These results suggest that AtT-20/D16v cells produce gamma MSH-LIs with molecular weights of 31K, 21-23K, 16-17K, 13-14K, and 3.8K, and they are secreted concomitantly with ACTH-LI and beta-EP-LI. (
  • Zebrafish proopiomelanocortin (zfPOMC) contains the consensus sequences for ACTH , gamma-LPH, beta-MSH and beta-endorphin (beta-END). (
  • The skin is a known target organ for the proopiomelanocortin (POMC)-derived neuropeptides alpha-melanocyte stimulating hormone (alpha-MSH), beta-endorphin, and ACTH and also a source of these peptides. (
  • The receptors for POMC peptides expressed in the skin are functional and include MC1, MC5 and mu-opiate, although most predominant are those of the MC1 class recognizing MSH and ACTH. (
  • Three similar peptides called alpha-, beta-, and gamma-melanocyte stimulating hormones (α-, β-, and γ-MSH) are also cut from the POMC protein. (
  • Decreased α-MSH in the skin reduces pigment production in melanocytes, which results in the red hair and pale skin often seen in people with POMC deficiency. (
  • The production of beta-MSH occurs in humans but not in mice or rats due to the absence of the enzymatic processing site in the rodent POMC. (
  • Entrez Gene: POMC proopiomelanocortin (adrenocorticotropin/ beta-lipotropin/ alpha-melanocyte stimulating hormone/ beta-melanocyte stimulating hormone/ beta-endorphin). (
  • In response to cannabinoids, drives the release of orexigenic beta-endorphin, but not that of melanocyte-stimulating hormone alpha/alpha-MSH, from hypothalamic POMC neurons, hence promoting food intake. (
  • The β-MSH peptide plays a role in weight regulation by binding to melanocortin 4 receptor (MC4R). (
  • The α-MSH peptide can also bind to MC4R and help maintain the correct energy balance. (
  • Another peptide, alpha-melanocyte stimulating hormone (α-MSH), plays a role in the production of the pigment that gives skin and hair their color. (
  • The α-MSH peptide and another peptide called beta-melanocyte stimulating hormone (β-MSH) act in the brain to help maintain the balance between energy from food taken into the body and energy spent by the body. (
  • Since MSH is technically a peptide, which isomer is found in the MSH2-Pro? (
  • Update: I should also note bremelanotide , another MSH-like peptide with a very long and convoluted history in the clinic, which is currently heading to the FDA for a controversial female sexual dysfunction indication). (
  • So here's a new paper on efforts to develop a more selective MSH peptide from the same group at Arizona that discovered afamelanotide. (
  • These receptors are activated by the peptide hormone α-MSH (melanocyte-stimulating hormone) and antagonized by the agouti-related protein. (
  • OBJECTIVE The aim of this research was to investigate endogenous concentrations and anti-cytokine effects of the antiinflammatory peptide alpha-melanocyte stimulating hormone (alpha-MSH) in patients with systemic inflammation. (
  • To determine whether alpha-MSH can modulate production of TNF-alpha and IL-1 beta, these cytokines were measured in whole blood samples stimulated with LPS (1 ng/mL) in the presence or absence of concentrations of the peptide. (
  • This inhibition by alpha-MSH, a peptide that is beneficial in treatment of experimental models of sepsis, might therefore be useful to treat sepsis syndrome in humans. (
  • Studies show that γ-MSH binds to melanocortin 3 receptor (MC3R). (
  • Pituitary melanotropes release alpha-melanocyte-stimulating hormone (alpha-MSH) and acetylated beta-endorphin (NAc beta-end) during stress responses. (
  • MSH (melanocyte stimulating hormone) increases the pigmentation of skin by increasing melanin production in melanocytes. (
  • MSH2 Pro™ contains melanocyte stimulating hormone , (or MSH), a substance that is directly involved in helping to tan the skin. (
  • The MC1 receptor (previously refered to as MSH-R) is the melanocyte-stimulating hormone receptor expressed in melanocytes and involved in the regulation of pigment production. (
  • Plasma alpha-MSH and acetylated beta-endorphin levels following stress vary according to CRH sensitivity of the pituitary melanotropes in common carp, Cyprinus carpio. (
  • The objectives were to determine the following: changes over time of plasma alpha-MSH and relationship with patient outcome, correlation between plasma alpha-MSH and tumor necrosis factor (TNF)-alpha plasma concentration and production in whole blood samples, and influences of alpha-MSH on production of TNF-alpha and interleukin (IL)-1beta in whole blood samples stimulated with lipopolysaccharide (LPS). (
  • RESULTS Plasma alpha-MSH was low in early samples and gradually increased in patients who recovered but not in those who died. (
  • These include several distinct melanotropins, lipotropins, and endorphins that are contained within the adrenocorticotrophin and beta-lipotropin peptides. (
  • Because expression of, for example, the MC1 receptor is stimulated in a similar dose-dependent manner by UVR, cytokines, MSH peptides or melanin precursors, actions of the ligand peptides represent a stochastic (predictable) nonspecific response to environmental/endogenous stresses. (
  • The origin of this variable response was investigated by (1) studying the effects of corticotropin-releasing hormone (CRH) on alpha-MSH and NAc beta-end release in vitro, (2) establishing where in the second messenger pathway coupled to CRH receptors melanotrope responsiveness is determined, and (3) testing modulatory actions of other hypothalamic factors (here opioid beta-endorphin). (
  • Structure-activity relationships of gamma-MSH analogues at the human melanocortin MC3, MC4, and MC5 receptors. (
  • It has been suggested that Agouti-related protein binds MSH receptors and acts as a competitive antagonist of ligand binding. (
  • Further cleavage of the subunit continues to produce alpha-ASH, which is the most influential MSH for skin pigmentation. (
  • α-MSH produced by neurons in the arcuate nucleus has important roles in the regulation of appetite and sexual behavior, while α-MSH secreted from the intermediate lobe of the pituitary regulates the production of melanin . (
  • Beta endorphin and Met enkephalin are endogenous opiates. (
  • And so far, this looks possible: their new species has better selectivity than endogenous MSH, and a longer half-life in human plasma (MSH's is five minutes, afamelanotide's is 30 minutes, and the new species is 17 minutes). (
  • The transcriptional activation of the Xtcf-3-target genes in response to endogenous Wnt/beta-catenin signaling by the overexpression of Xtcf-3BDN- led to a reduction of the ventral diencephalon . (
  • The fetal porcine pituitary was studied to detect by means of the immunoperoxidase technique the earliest stages of cells producing polypeptide hormones: .beta. (
  • Note: Technically the natural MSH is called an intermedin since it is produced in the intermediate lobe of the pituitary gland. (
  • Addition of alpha-MSH to LPS-stimulated blood samples reduces production of cytokines involved in development of septic syndrome. (
  • The Melanotropin beta gene encodes a polypeptide hormone precursor that undergoes extensive, tissue-specific, post-translational processing via cleavage by subtilisin-like enzymes known as prohormone convertases. (
  • Previously, MSH had to be injected, but now MSH2-Pro™ provides this hormone via an effective intra-nasal spray, thus doing away with the need for needles. (
  • MSH) having selectivity for the melanocortin 1 receptor. (
  • The primary role of α-MSH is in the pigment-producing cells of the skin and hair (melanocytes), where it binds to melanocortin 1 receptor (MC1R). (
  • Here, we show that also within a species, the common carp (Cyprinus carpio), fish sometimes respond with elevated alpha-MSH and NAc beta-end plasma levels, and at other times not. (
  • Melanotropes were in a high or low responsive state to CRH in vitro, which was especially evident when tissue was tested from fish kept at higher ambient water temperatures, and this correlates with the variability in alpha-MSH and NAc beta-end responses in vivo. (
  • Relative rates of alpha-MSH and NAc beta-end release following stimulation with CRH in vitro match plasma level changes in vivo, and this indicates that the CRH pathway does act in vivo. (
  • Opioid beta-endorphin differentially modulated the actions of CRH, as NAc beta-end, but not alpha-MSH, release was inhibited. (
  • This latter effect is an example of a "catecholamine reversal", characteristic of alpha adrenergic blocking agents, which results from alpha adrenergic inhibition and consequent beta adrenergic stimulation. (
  • The inhibition and reversal of MSH-induced darkening by haloalkylamine alpha antagonists and mercurials also suggests a role for sulfhydryls in MSH activity. (
  • These actions of Dibenamine and phenoxybenzamine also indicate a possible common sulfhydryl requirement for MSH and the alpha adrenergic receptor. (
  • By now, humans have three forms of the latter (alpha, beta, and gamma MSH), and the receptor proteins have branched into five different MCxR subtypes as well. (
  • They are also very important in the regulation of appetite , and, when activated, they inhibit feeding, mainly via the effects of alpha MSH. (
  • METHODS Circulating alpha-MSH and TNF-alpha concentrations and TNF-alpha production in supernatants of LPS (1 ng/mL)-stimulated whole blood were measured repeatedly. (
  • There was a negative correlation between plasma concentrations of alpha-MSH and TNF-alpha. (
  • Addition of alpha-MSH to LPS-stimulated whole blood samples inhibited production of TNF-alpha and IL-1beta in a concentration-dependent manner. (
  • CONCLUSIONS In patients with systemic inflammation, there are substantial changes over time in plasma concentrations of alpha-MSH that are reduced in early phases of the disease. (
  • Antiserum to beta Endorphin was raised in rabbits by using the N-terminal portion of bovine beta Endorphin conjugated to thyroglobulin. (
  • MC1R is the receptor signaling mechanism for melanin production, and is activated by MSH. (
  • Together, MC3-R and/or MC-4R mRNA are found in every nucleus reported to bind MSH in the adult rat brain and define neuronal circuitry known to be involved in the control of diverse neuroendocrine and autonomic functions. (
  • Whereas α-MSH acts broadly on most members of the MCR family (with the exception of MC2-R), AGRP is highly specific for only MC3-R and MC4-R. This inverse agonism not only antagonizes the action of melanocortin agonists such as α-MSH but also further decreases the cAMP produced by the affected cells. (
  • The protein blocks α-MSH-induced secretion of corticosterone. (
  • Beta MSH-Shares the 17 amino acids at the C-terminal of gamma-lipotropin. (
  • Although the N-terminal 5 amino acids of beta-endorphin are identical to the sequence of Met-enkephalin, it is not generally thought that beta-endorphin is converted into Met-enkephalin. (
  • An orally available, competitive, beta-amino acid-derived inhibitor of dipeptidyl peptidase 4 (DDP-4) with hypoglycemic activity. (
