Abstract The utilization of E. pellita bark as waste is still not widely carried out due to a lack information about the chemical content. Therefore, current study aimed analyze content using pyrolysis-gas chromatography-mass spectrometry (PyGCMS). results showed total extractive pellita’s inner bark, outer and mix-bark was 12.17%, 16.19%, 14.85%, respectively. holocellulose 65.45%, while were ...

The distribution of catechol-O-methyl transferase and monoamine oxidase activity in the ocular tissues of albino rabbits has been determined with a radioactive tracer assay. The distribution of the former varied in the different tissues within a restricted range whereas the distribution of monoamine oxidase activity exhibited larger variations. Sympathetic denervation did not appear to affect c...

Dose-response curves of increase in pupil size and decrease in intraocular pressure with topical epinephrine have been determined in the sympathetically denervated rabbit eye. Topical pretreatment with the catechol-O-methyl transferase inhibitor U-0521 potentiated the effects of epinephrine on both the pupil and pressure. These observations suggest a possible role for catechol-O-methyl transfer...

1. L-DOPA was administered to rats by twice daily intraperitoneal injection for a period of eleven days. The daily dose was gradually increased from 250 mg/kg to 1 g/kg. The animals were killed 12 h after the last injection and tissue catechol-O-methyl transferase, DOPA-decarboxylase and monoamine oxidase activity determined.2. Catechol-O-methyl transferase activity was reduced in the liver (46...

Ovarian cancer is associated with the highest mortality rate among gynaecological malignancies (Hennessy et al., 2009). There are over 205, 000 new cases and 125, 000 deaths annually from ovarian cancer (Jemal et al., 2011). Endometrial cancer is the fourth most common cancer among women and the most common gynecological cancer in the USA (Jemal et al., 2009). Multiple lines of evidence support...

The yields of char, tar, and non-condensible gases from the pyrolysis of Pinus radiata D. Don bark were measured. Pyrolysis of bark, on a small preparative scale using an airacetylene flame, gave 48% char with ash content 3.5% (mainly aluminium, calcium, potassium, and silica), and recovered tar in 7% yield (on oven-dried bark equivalent). The major components of the pyrolysis tar were catechol...

Earlier reports from these laboratories outlined the preparationx) and biological properties2>3) of 6a-formamido penicillins. The catecholic acylureido derivative BRL 36650 (1) was the most potent, especially against Pseudomonas aeruginosa strains.

Catechol chemistry is used as a crosslinking tool abundantly in both natural organisms (e.g. mussels, sandcastle worms) and synthetic systems to achieve the desired mechanical properties. Despite this abundance and success, the crosslinking chemistry is still poorly understood. In this study, to simplify the system, yet to capture the essential chemistry, model compounds 4-methyl catechol and p...
