Studies demonstrate that TB-500 is a potent, naturally occurring wound repair factor with anti-inflammatory properties. Tß4 is different from other repair factors, such as growth factors, in that it promotes endothelial and keratinocyte migration. It also does not bind to the extracellular matrix and has a very low molecular weight meaning it can travel relatively long distances through tissues. One of TB-500 key mechanisms of action is its ability to regulate the cell-building protein, Actin, a vital component of cell structure and movement. Of the thousands of proteins present in cells, actin represents up to 10% of the total proteins which therefore plays a major role in the genetic makeup of the cell.
Osteoclast differentiation was assessed by tartrate-resistant acid phosphatase (TRAP) staining and activity. After 5 days of culture, cells were stained for TRAP kit using a leukocyte acid phosphatase kit (Sigma Aldrich, St Louis, MO, USA). Cells with three or more nuclei were counted as multinucleated mature osteoclasts. To measure TRAP activity, cells were fixed with 10% formalin for 10 min and 95% ethanol for 1 min, and then 100 μl of citrate buffer (50 mM, pH 4.6) containing 10 mM sodium tartrate and 5 mM p-nitrophenylphosphate (Sigma-Aldrich) was added to the wells containing fixed cells in the 48-well plates. After incubation for 1 h, enzyme reaction mixtures in the wells were transferred to new plates containing an equal volume of 0.1 N NaOH. Absorbance was measured at 410 nm using a microplate reader.
Do I have to diet? Studies show that 5-HTP enhances weight loss even if you continue eating your normal foods. Without a diet, you stand to lose about a pound a week; many folks eventually drop 15 pounds or more without dieting. Of course, taking 5-HTP to lose weight works by lowering caloric intake — and the more calories you cut, the more you’ll lose. So if you want to maximize results, try tweaking your diet at the two-week mark, when 5-HTP will have fully kicked in, diminishing hunger and carb cravings. Below, we’ve got a version of the diet used in one university study that helped 5-HTP takers lose several times more weight than folks getting a placebo.
Again, the three groups of mice were exposed to the stressful experience of social defeat in the cages of other more aggressive mice. This time, six hours after the social stress, the mice were put in a box in which they received a brief electric shock, which startles them but is not painful. Then 24 hours later, the mice were returned to the same box but did not receive a shock.

Skin is the largest organ of the body, which makes up 16% of total body weight. It is also the largest organ that provides immune protection and plays a role in inflammation. Composed of specialized epithelial and connective tissue cells, skin is our major interface with the environment, a shield from the outside world and a means of interacting with it. As such, the skin is subjected to insults and injuries: burns from the sun’s ultraviolet radiation that elicit inflammatory reactions, damage from environmental pollutants and wear and tear that comes with aging.
To pursue the sexual dysfunction agent, melanotan-II was licensed by Competitive Technologies to Palatin Technologies.[9] Palatin ceased development of melanotan-II in 2000 and synthesized, patented, and began to develop bremelanotide, a likely metabolite of melanotan-II that differs from melanotan-II in that it has a hydroxyl group where melanotan-II has an amide.[6][13] Competitive Technologies sued Palatin for breach of contract and to try to claim ownership of bremelanotide;[13] the parties settled in 2008 with Palatin retaining rights to bremelanotide, returning rights to melanotan-II to Competitive Technologies, and paying $800,000.[14]
Melanotans include melanotan I (afamelanotide) and melanotan II. Both melanotan I and II are widely abused to obtain a cosmetic tan. The melanotans are potent, non-selective melanocortin receptor agonists affecting MC1, MC3, MC4 and MC5 receptors. These receptors are responsible for many physiological systems including: pigmentation, energy, sexual function, immune system, inflammation and the cardiovascular system.
This mother-child bonding is the most glorified myth that is not re-thought as often as it should. Its apparant purpose is just to make a dangerously selfish mother (such frustrated mothers do exist a lot more than we read in the news) to think twice before harming her defenseless child which is oftentimes in her sole custody in our society. Acts of such mothers are branded as mental illness rather than plain cruelty. While most people (men and women alike) tend to protect, and not harm a child, the real bonding can happen beetween two independent, mature adults.
If the two things you can't live without are a dark, even tan and a fast-acting, long-lasting erection, then add Melanotan II to your holiday shopping list. This synthetic peptide hormone, which was developed by a research team at the University of Arizona during the late 1990s, darkens skin pigment and may stimulate erectile activity. And despite continued concern and controversy within the medical community regarding its use, it remains available for sale over the internet in a powdered form that can then be reconstituted for subcutaneous injections.
The pore-forming subunit of the cardiac sodium channel Nav1.5 encoded by SCN5A is a critical determinant of myocardial excitability and conduction. Loss-of-function mutations in SCN5A can clinically manifest as progressive cardiac conduction disorders or as arrhythmic syndromes, such as Brugada syndrome. In addition to electrophysiological dysfunction, SCN5A mutations are also associated with myocardial fibrosis manifesting as global cardiomyopathy. In a 10-year old child exhibiting Brugada syndrome, the mutation SCN5AE555X was discovered. Therefore, cardiac sodium channelopathy pig models were generated by homologous recombination in the genetic background of outbred Yucatan minipigs via SCNT exhibiting the orthologous porcine heterozygous mutation SCN5AE558X. The heterozygous mutant animals were viable and fertile, and showed no sudden death over a 2-year monitoring period. They showed reduced SCN5A protein expression, which resulted in diminished total sodium conductance. The heterozygous mutant hearts showed slowed conduction and increased susceptibility for ventricular arrhythmias in the absence of structural defects of the myocardium or specialized conduction system. In total, a novel animal model was established for understanding the mechanisms linking sodium channel dysfunction to cardiac pathophysiology (Park et al., 2015b).
Uterine contractions. These are important for cervical dilation before birth and causes contractions during the second and third stages of labor. Oxytocin release during breastfeeding causes mild but often painful uterine contractions during the first few weeks of lactation. This also serves to assist the uterus in clotting the placental attachment point postpartum. However, in knockout mice lacking the oxytocin receptor, reproductive behavior and parturition is normal.16

Double immunofluorescent staining for BrdU (red, A) and NeuN (green, B) to identify newborn neurons (yellow after merge, C) in the dentate gyrus of hippocampus from rats examined 35 days after TBI. Micrographs (D) show location of DiI injection in the CA3 region (indicated by white asterisk). In the CA3 region, axons projected from granule neurons in the dentate gyrus will take up injected DiI to their cell bodies. Co-localization (merge, H) of BrdU-positive nuclei (green, F) within retrogradely DiI labeled (red, E) granule cells were examined at 35 days after TBI. Scale bar = 25 μm (C, H). Scale bar = 50 μm (D).
The peripheral actions of oxytocin mainly reflect secretion from the pituitary gland. The behavioral effects of oxytocin are thought to reflect release from centrally projecting oxytocin neurons, different from those that project to the pituitary gland, or that are collaterals from them.[31] Oxytocin receptors are expressed by neurons in many parts of the brain and spinal cord, including the amygdala, ventromedial hypothalamus, septum, nucleus accumbens, and brainstem.[citation needed]

Last month, in the article “How To Use BPC-157: A Complete Dummies Guide To Healing The Body Like Wolverine“, I introduced the little-known concept of using BPC-157 peptide self-injections and oral BPC-157 peptide consumption (currently completely legal and not banned by sporting organizations) for everything from rapidly healing leaky gut to fixing tendon, ligament and muscle injuries.
There have been encouraging results for the use of Tβ4 as a topical gel to treat venous stasis ulcers, a type of wound that develops on the lower leg of patients with chronic vascular disease. Two other reports indicated that Tβ4, formulated in eye-drops, may enhance corneal wound healing in diabetic patients, and improve ocular discomfort. These are the most advanced trials to date. As of yet, despite promising animal models, there has been no significant study exploring the efficacy of intravenous Tβ4 injections in treating ischemic heart injury.
Oxidative stress is characterized by an accumulation of ROS and plays a key role in the progression of periodontal diseases [24]. Damage of tissues in inflammatory periodontal disease can be mediated by ROS resulting from the physiological activity of PMN during the phagocytosis of periodontopathic bacteria [27]. In addition, LPS from Porphyromonas gingivalis as well as hypoxia induces a NOX4-dependent increase in H2O2 release in PDLCs [28]. Furthermore, ROS such as H2O2 are small, diffusible, and ubiquitous molecules, can affect human PDLCs and gingival fibroblasts cell injury indirectly by enhancing pro-inflammatory factors such as cytokines, NO, PGE2, and ROS [29–31]. This ROS is known to stimulate osteoclast differentiation and participate in early signaling events associated with osteoclast activation for bone resorption [32]. Since LPS from P. gingivalis increases oxidative stress in PDLCs and contributes to periodontitis [28], human PDLCs treated with H2O2 may serve as an in vitro model relevant to periodontitis.
In humans, the Tβ4 gene TMSB4X is localized to the X chromosome at Xq21.3–q22 (). The Tβ4 cDNA open reading frame contains an initial methionine codon followed by a codon for the N-terminal serine and, although cells secrete a certain amount of Tβ4, there is no hydrophobic signal sequence. The initial methionine residue of the nascent Tβ4 polypeptide is removed and the N-terminal serine residue is often acetylated in the cells.
Oxytocin's story starts back in the early 1900s, when biochemists discovered that a substance from the posterior pituitary gland could promote labour contractions and lactation. When scientists later discovered the hormone responsible, they named it oxytocin after the Greek phrase meaning 'rapid birth'. Oxytocin is produced mainly by the brain's hypothalamus; in the 1970s, studies revealed that oxytocin-producing neurons send signals throughout the brain, suggesting that the hormone had a role in regulating behaviour.
Second, 5-HTP can cause serious drug interactions with many medications, especially those used to treat depression. Because antidepressants generally work by increasing serotonin in the brain, 5-HTP could combine with these medications to cause high concentrations of serotonin. Having too much serotonin can lead to serotonin syndrome, a serious condition characterized by dangerously high heart rate, blood pressure, and temperature. 5-HTP can interact with other classes of drugs, like migraine and pain medications, that also affect serotonin concentrations.

Oxytocin affects social distance between adult males and females, and may be responsible at least in part for romantic attraction and subsequent monogamous pair bonding. An oxytocin nasal spray caused men in a monogamous relationship, but not single men, to increase the distance between themselves and an attractive woman during a first encounter by 10 to 15 centimeters. The researchers suggested that oxytocin may help promote fidelity within monogamous relationships.[109] For this reason, it is sometimes referred to as the "bonding hormone". There is some evidence that oxytocin promotes ethnocentric behavior, incorporating the trust and empathy of in-groups with their suspicion and rejection of outsiders.[66] Furthermore, genetic differences in the oxytocin receptor gene (OXTR) have been associated with maladaptive social traits such as aggressive behavior.[110]
Cells were pretreated with indicated concentrations of Tβ4 peptide for 2 hours and then incubated with 200 μM H2O2 for 48 hours (A-C). Protein expressions were assessed by Western blot analysis (A). The production of NO (B) and PGE2 (C) were measured by Griess reaction and ELISA, respectively. Data replicated the quantifications of NO and PGE2 with the standard deviation of at least three experiments (n = 4). The bar graph shows the fold increase in protein expression compared with control cells. * Statistically significant differences compared with the control, p<0.05. # Statistically significant difference compared with the H2O2—treated group.
Research in the early 1960s showed that in rats, administration of α-MSH caused sexual arousal, and work on this continued in many labs up through the 1980s, when scientists at University of Arizona began attempting to develop α-MSH and analogs as potential sunless tanning agents, and synthesized and tested several analogs, including melanotan-I and melanotan II.[6][9]

First developed in the 1980s by researchers at the University of Arizona, Melanotan is principally used for the treatment of skin disorders including vitiligo and erythropoietic protoporphyria that affect skin appearance and sensitivity (especially to sunlight). By promoting melanin in the skin, Melanotan can help ease the symptoms of these conditions and enable those diagnosed to live a more normal life.
Dietary supplements containing 5-HTP are claimed to help promote feelings of happiness and general well-being as well as a wide range of other positives such as appetite control, reduced anxiety, and improved mood, sleep and feelings of relaxation. However, there is no conclusive evidence showing that it is effective, and there is no clear "therapeutic" dose of 5-HTP.

RegeneRx is continuing with pre-clinical research, in collaborative arrangements with the National Institutes of Health, accumulating data on the effects of Tb4 and aiming for an IND application (Investigational New drug App-lication) to proceed with clinical studies. Phase I clinical trials will determine the ability of Tb4 to repair ulcers in diabetic patients and to reduce inflammation and accelerate recovery from burns and abrasions to the cornea.
But what about the three-month warning? Dr Rush, while an advocate for the supplement, sees it as a short-term solution, and not something to rely on long-term, for good reason. "Technically taking 5-HTP alone can deplete important brain chemicals such as dopamine and adrenaline. While 5-HTP is aimed at increasing the amount of serotonin in the body, dopamine and adrenaline are also important for positive mental health states. In order to prevent the depletion of important brain chemicals, taking 5-HTP would need to be balanced with amino acids that support the production of dopamine and adrenaline." That's L-Tyrosine, which you eat in soy, chicken and beef, and can also be found in health food shops as a supplement.
“This is a very ancient molecule,” says Sue Carter, a neuroscientist at Indiana University in Bloomington, whose lab pioneered many of the early studies of oxytocin in voles. “It has been used and reused for many purposes across the evolution of modern animals, and almost everybody who's tried to look at an effect of oxytocin on anything like social behaviour has found something.”
The tb-500 has a systematic effect regardless of where it is injected. Some believe that thymosin beta-4 should be injected as close to the injury as possible however there is no evidence to show this would be superior. It can be injected subcutaneously (stomach fat) or intramuscularly (shoulders, thighs, buttocks). Injections should be given in different sites (rotated) each time. Depending on the spot, you can either feel nothing or you can feel slight pain - you will learn your favorite spots in time.
The main functionality of TB500 hinges on the ability to upregulate cell building proteins such as actin, which is a protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion and metabolism in many other types of cells.. Upregulation of actin allows TB500 to promote healing, cell growth, cell migration and cell proliferation. This not only helps build new blood vessel pathways but also upregulates the type of “good” inflammation that is directly correlated with faster wound healing.
Animal studies have found high levels of both stress and oxytocin in voles that were separated from other voles. However, when the voles were given doses of oxytocin, their levels of anxiety, cardiac stress, and depression fell, suggesting that stress increases internal production of the hormone, while externally supplied doses can help reduce stress.
As reactive oxygen species (ROS) have been implicated in the pathogenesis of periodontitis [24], we examined whether H2O2 could down-regulate or up-regulate Tβ4 expression in PDLCs. As shown in Fig 1A and 1B, Tβ4 mRNA and protein expressions were down-regulated by H2O2 in a time- and concentration-dependent manner. Because maximal Tβ4 mRNA and protein expressions were achieved with 200 μM H2O2 within 48 hours in PDLCs, this concentration was used in subsequent experiments.

The hormone does not act alone. In 2013, neuroscientist Robert Malenka at Stanford University in California and his colleagues showed that oxytocin works together with the neurotransmitter serotonin to reduce the excitability of neurons in the nucleus accumbens9, a brain region involved in reward. This process seems to support the preference of mice to return to environments where they had rewarding social interactions with other animals. “Oxytocin is part of a system,” Carter says, “and it's not the only molecule that matters, but it's one that in some way is regulatory over a large number of other systems.”
In the end, despite three years of intense scrutiny, the drug at the centre of the investigation remains poorly understood. In this regard, it could serve as a reflection of the whole ordeal. Everyone has an opinion, often voiced with authority and conviction. The reality is that much of this complex narrative continues to be a mystery. Many would have been well served by the humble words of the Socratic paradox – “I know that I know nothing”.
Why have zebrafish retained the ability to regenerate? It is thought that the capacity for organ regeneration is an ancestral condition that has occasionally been diminished in the course of vertebrate evolution (Scadding, 1977; Goss, 1992; Wagner and Misof, 1992). Thus, most biologists suspect that the molecular machinery to optimize regeneration is present but poorly-utilized in mammals. By this line of reasoning, zebrafish heart regeneration may represent an optimal utilization of universal cardiac machinery.
Virtually all vertebrates have an oxytocin-like nonapeptide hormone that supports reproductive functions and a vasopressin-like nonapeptide hormone involved in water regulation. The two genes are usually located close to each other (less than 15,000 bases apart) on the same chromosome, and are transcribed in opposite directions (however, in fugu,[44] the homologs are further apart and transcribed in the same direction).
Reconstituting tanning peptide is a part of the process required for use of the product and will require full attention to get proper results. 1 or 2ml sterile water is usually used, diluting with more water will improve dosing accuracy. Lovemelanotan peptide calculator is ideal tool for anyone just starting out and not sure how to reconstitute or dose the product properly.
