“L-5-Hydroxytryptophan significantly reduced the reaction to the panic challenge in panic disorder patients, regarding subjective anxiety, panic symptom score and number of panic attacks, as opposed to placebo. No such effect was observed in the healthy volunteers. L-5-Hydroxytryptophan acts to inhibit panic, which supports a modulatory role of serotonin in panic disorder.”
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, the homologs are further apart and transcribed in the same direction).
The relationship between oxytocin and human sexual response is unclear. At least two non-controlled studies have found increases in plasma oxytocin at orgasm in both men and women. The authors of one of these studies speculated that oxytocin's effects on muscle contractibility may facilitate sperm and egg transport. Murphy et al. (1987), studying men, found that oxytocin levels were raised throughout sexual arousal and there was no acute increase at orgasm.  A more recent study of men found an increase in plasma oxytocin immediantly after orgasm, but only in a portion of their sample that did not reach statistical significance. The authors noted that these changes "may simply reflect contractile properties on reproductive tissue."
Some differences in cardiac anatomy exist between mammals and teleosts. The zebrafish ventricle has a thin wall of compact muscle surrounding a much larger compartment of myofibers organized into elaborate trabeculae. It is intriguing that this structure is very similar to that of the embryonic mammalian ventricle prior to its septation and fusion of trabeculer myofibers into a thick, vascularized wall (Sedmera et al., 2000). That the mammalian heart has a more differentiated, contractile anatomy is apparent not only in gross cardiac structure, but also in cellular features. Teleost cardiomyocytes are 2–10 times smaller, mononucleated, have a greatly-reduced sarcoplasmic reticulum and lack the T-tubule system found in skeletal muscle and mammalian cardiac muscle (Farrell, 1992). One might speculate that the teleost heart is better designed for growth and regeneration, while the mammalian heart is better designed for sheer contractile force. Nevertheless, none of the mentioned differences between lower and higher vertebrate hearts preclude the idea that the mammalian heart could be stimulated to regenerate, especially if that regeneration is due to mobilization of a progenitor cell population.
Although research has shown that good communication predicts relationship success, successful communication in couples therapy won’t ensure that partners stay together. The goal is to help the two people understand each other’s point of view and come to a mutual decision, even if it’s to break up. “If people are not connected at all, then oxytocin is not going to force that connection,” Guastella says.
Oxytocin production is controlled by a positive feedback mechanism. This mechanism allows the release of the oxytocin hormone when a trigger occurs. The hormone then causes an action in the body, such as the letdown of milk or the start of labor contractions, which signals more production of oxytocin. The feedback cycle continues until the action, such as childbirth or feeding the baby, is complete.
Work with cell cultures and experiments with animals have shown that administration of thymosin β4 can promote migration of cells, formation of blood vessels, maturation of stem cells, survival of various cell types and lowering of the production of pro-inflammatory cytokines. These multiple properties have provided the impetus for a worldwide series of on-going clinical trials of potential effectiveness of thymosin β4 in promoting repair of wounds in skin, cornea and heart.
When practicing deep breathing, focus on a calmer state of mind as you distract yourself from overwhelming thoughts and sensations. Sit in a quiet area and practice the following: Take a slow, deep breath through your nose, allowing both your stomach and chest to rise. Once your stomach is fully expanded, breathe out through your mouth, just as slowly as when you were breathing in.
Unlike previous studies, the trial will include people with a wide range of symptoms — and one of its major aims is to uncover the set of factors that influence whether and how strongly people respond to oxytocin. Sikich will analyse many measures of cognition and social functioning, and collect blood samples to look for biomarkers — such as levels of oxytocin and the receptor it binds to — that are associated with a response. “Lin has really been trying to create conditions under which you could study the potential beneficial effects of oxytocin and really do this right,” says Carter.
One study investigating romantic stress that looked at nondepressed youth who went through a recent breakup and were given 60mg of Griffonica Simplicifonia (12.8mg 5-HTP) twice a day for 6 weeks in an open-label study noted reductions in percieved romantic stress when measured at the 3 week mark with no further improvement at 6 weeks; there was no control nor placebo group in this study.
Plain sterile water is the most suitable diluent for TB-500. Alternatively it can be reconstituted with sterile saline (0.9% NaCl) or sterile bacteriostatic water (0.9% sodium chloride). Plain sterile water should be readily available to buy without prescription in any local pharmacy. Alternatively it can also be purchased online. It is even available on ebay.
Ok Ben. Thanks. Started the TB 500 for my elbows. Got the 5mg of TB 500 and reconstituted it with 3 cc/ml. of water (3 syringes full) Just about filled the file. Now based on injecting just under .1 cc/ml or just under 10 (8) units for a dose of around 250. How long did that vial last you? Seems like there is a lot left and the amount injected is small. Is my dose and math right?
What we noticed was that all the rats that had received oxytocin straight into their brain immediately prior to being given alcohol, were up and moving about and seemed to be completely sober. Whereas all of the rats that had just been given the alcohol were, as we would predict from the dose that we were giving them, quite drunk. And so we thought, 'Wow, what's going on here?' It was almost as though the oxytocin was blocking the intoxicating effects of the alcohol.
Potential side effects of 5-HTP include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, vivid dreams or nightmares, and muscle problems. Because 5-HTP has not been thoroughly studied in a clinical setting, possible side effects and interactions with other drugs are not well known. According to the US National Institute of Health TOXNET, 5-HTP has not been associated with serotonin syndrome or any serious adverse events in humans. Across multiple studies, 5-HTP also been reported to not cause any noticeable hematological or cardiovascular changes. 5-HTP also has not been associated with eosinophilia.
