What is 7-hydroxy-mitragynine?

7-Hydroxymitragynine (7-hydroxy-mitragynine) is a terpenoid indole alkaloid in the plant Mitragyna speciosa, commonly known as Kratom. It has opioid agonistic activity. "The potency, calculated using pD (2) values, was 30-fold higher than that of mitragynine and 17-fold higher than that of morphine, respectively. Antagonism of naloxone on concentration-response curves for 7-hydroxymitragynine confirmed its opioid effect. These results suggest that the opioid effect of M. speciosa is mostly based on the activity of 7-hydroxymitragynine."
7-Hydroxymitragynine is orally active in animals as an analgesic,and produces normal opioid side effects including constipation, though significantly less than morphine, development of tolerance and withdrawal syndrome upon abstinence.The O-acetyl ester (Acetoxy), 7-acetoxymitragynine has also been reported and found to be an active μ-opioid agonist.

What is Iridium powder?

Iridium, atomic number 77, the atomic weight of 192.22, the element's name comes from the Latin, original intention is "rainbow". In 1803, a British chemist tennant, French chemist's scottie dissolved in aqua regia coarse platinum, from the residue in the bottom of the vessel discovered two new elements in black powder - osmium and iridium. Iridium in content in the earth's crust is one over ten million, often scattered with platinum group elements in alluvial deposits and placer deposit in all kinds of ores. Nature exists two isotopes: iridium 191, iridium 193.

Chemical properties of iridium is stable. Is the corrosion resistance of the metal, iridium for high chemical stability, acid insoluble in acid, only the spongy iridium will slowly dissolved in aqua regia, hot if it is a dense state of iridium, even boiling aqua regia, nor corrode iridium; Slightly by molten sodium hydroxide, potassium hydroxide and sodium dichromate. Generally the etchant can corrosion iridium. Has a tendency to form the coordination compounds have strong. Main valence + 2, + 4, + 6.

Information about CA195 ELISA Kit

To authorize added the analytic acceptation of the CA-195 bike immunoradiometric appraisal in gastro-intestinal malignancies, the sera of a absolute of 222 capacity accept been analysed and compared with assays of the "classical gastrointestinal tumour markers", CA19-9 and carcinoembryonic antigen (CEA). CA-195 elevations aloft accustomed (greater than 10 U/ml) were acclaimed in 51/72 (70.8%) colorectal, 15/15 (100%) pancreatic, and in 6/12 (50%) belly blight patients. Admitting CA19-9 was added (greater than 37 U/ml) in 65%, 93%, and 42% of cases, alone 54% colorectal, 45% pancreatic, and 42% belly blight patients had pathologically animated serum CEA levels (greater than 5 ng/ml). No aberrant access of both CA-195 and CA19-9 was begin in advantageous volunteers, admitting 3/20 (smoking) individuals had CEA levels hardly aloft normal. With a 29% false-positive amount acclaimed a part of 103 patients with amiable gastrointestinal disorders, the specificity of CA-195 was above to that of CA19-9 (58%) and commensurable with that of CEA (31%). A cogent alternation amid CA-195 levels and the clinical/pathological date of ache was acclaimed in colorectal (P beneath than 0.01) and pancreatic blight patients (P beneath than 0.007). Preliminary after-effects of consecutive abstracts of CA-195 in colorectal blight advance that this new brand protein, which has no cross-reactivity with CEA, may be advantageous as a non-invasive analysis for postoperative surveillance of patients to ascertain ache recurrence, and serve to accompaniment (though absolutely not replace) accepted analytic abstracts of acknowledgment to chemotherapy.
