This is it. Were a mere two shakes of a lambs tail from releasing the final version of Rails 1.2. But before we light the fireworks and pop the champagne, well just do one itsy, bitsy, tiny test run. Like wearing protection glasses in downtown Copenhagen on New Years. You know, just for precautions. So please do give it a good run. Were looking for STOP THE BOAT and HOLD THE PRESSES kind of issues for this one. Nothing else will stop it (but please do report every thing you find any way). For a reminder on how to install and whats new, see the release notes for Release Candidate 1. We also did a series of highlights for Active Record, Action Pack, and Active Support. Read those and hold your breath in anticipation. Unless a surge of heinous issues appear, were expecting the final version to land some times next week. Yay, hurray!
en] Cytochrome P-450-dependent monooxygenases are able to oxidize a large variety of endogenous and exogenous substrates. This paper describes the in vitro interaction between benzopyrene and steroids at the level of two rat liver monooxygenases: steroid-16 alpha-hydroxylase and aryl hydrocarbon hydroxylase (AHH). The results obtained suggest the following conclusions: (1) Steroid-16 alpha-hydroxylase is partially supported by a specific cytochrome P-450 form which is not inhibited in vitro by exogenous substrates. Steroid-16 alpha-hydroxylase is completely independent from cytochrome P1-450 (or P-448), as it is insensitive, in vitro, to alpha-naphthoflavone; (2) AHH is supported by two cytochrome P-450 forms: a specific form which is inducible by methylcholanthrene and inhibited in vitro by alpha-naphthoflavone, but is insensitive to metyrapone and steroids; and another less specific form which is inhibited by metyrapone and steroids in vitro ...
Kinetic and inhibitor studies using cDNA-expressed enzymes and human liver microsomes have characterized the specificity of a range of cytochrome P450 (CYP) 1A substrate and inhibitor probes towards the two isoforms comprising this subfamily. Expressed CYP1A1 and CYP1A2 both catalyzed the O-deethylation of phenacetin, although the apparent Km was about 4-fold lower for CYP1A2 (25 vs. 108 microM). Phenacetin O-deethylation exhibited biphasic kinetics in human liver microsomes, and the apparent Km for the high-affinity component (9 +/- 6 microM) was consistent with the involvement of CYP1A2 in this reaction. The prototypic CYP1A xenobiotic inhibitor and substrate probes alpha-naphthoflavone, ellipticine, 7-ethoxycoumarin and 7-ethoxyresorufin all inhibited CYP1A1- and CYP1A2-mediated phenacetin O-deethylation as well as the high-affinity component of human liver phenacetin O-deethylase activity. alpha-Naphthoflavone and 7-ethoxycoumarin were, however, approximately 10-fold more potent as ...
We have analyzed the possible role of the aryl-hydrocarbon receptor (AHR) in the aging process of mice using a homozygous null mouse (Ahr-/-) line as a model. We studied 52 male and female Ahr-/- mice aged from 6-13 months. Forty-six percent died or were ill by 13 months of age. Ahr-/- mice developed age-related lesions in several organs, some of which were apparent after only 9 months of age. Cardiovascular alterations included cardiomyopathy (100%) with hypertrophy and focal fibrosis. Vascular hypertrophy and mild fibrosis were found in the portal areas of the liver (81%), and vascular hypertrophy and mineralization were common in the uterus (70%). Gastric hyperplasia that progressed with age into polyps was evident in the pylorus of 71% of the mice over 9 months of age. Ahr-/- mice had T-cell deficiency in their spleens but not in other lymphoid organs. The immune system deficiency described previously could be the origin for the rectal prolapse found in 48% of the null mice, associated

Phthalates are esters of 1,2-benzoldicarbonic acid (ortho-phthalic acid). The chemical structure of phthalates can be characterised by a planar aromatic ring with two slightly mobile side chains. For phthalates, in general, side chains are mainly alkyl groups with a secondary role played by allyl, benzyl, phenyl, cycloalkyl and alkoxy groups. With alkyl phthalates, a further distinction can be made between branched and unbranched side chains.. In the early 1980s, annual, world-wide production of phthalate esters was estimated to be 20 million tonnes (Schmitzer et al, 1988), although it may now be closer to 5 million tonnes (Lewis et al 1998). The total consumption of phthalate esters in the UK was estimated to be 122,000 tonnes in 1989, of which 54% was DEHP and DIOP (Brooke et al 1991).. Phthalates esters are manufactured world-wide on a large scale, being mainly produced for use as plasticisers in resins and polymers, especially as a softener in PVC (87% of the total production of phthalates ...
The specific inactivation of rabbit cytochromes P-450 2C by 17 beta-substituted steroids has been investigated by using purified, Escherichia coli-expressed enzymes. The expressed P-450s provided a means to characterize accurately the effects of 21,21-dichloroprogesterone, 21,21-dichloropregnenolone, 21-chloro-21-fluoropregnenolone, pregn-5,20-diene-3 beta-ol and pregn-4,20-diene-3-one on progesterone hydroxylation by P-450 2C5, 2C4, 2C3 and 2C3v. Previous studies using rabbit liver microsomes had suggested that 21-chloro-21-fluoropregnenolone is a selective inactivator of 2C5, a progesterone 21-hydroxylase. Studies of the expressed P-450 2C forms showed little selectivity of 21,21-dichloroprogesterone, pregn-5,20-diene-3 beta-ol or pregn-4,20-diene-3-one, whereas 21,21-dichloropregnenolone and 21-chloro-21-fluoropregnenolone preferentially inactivate 2C5. The data indicate the importance of progesterone 21-hydroxylase activity in facilitating selective mechanism-based inactivation of 2C ...

Environmental exposure to carcinogens may contribute to increasing breast cancer rates and geographic variation in breast cancer incidence in the United States. One class of chemicals that has received much attention are the polyaromatic hydrocarbons that are ubiquitous in the environment and occur in cigarette smoke. The cytochrome P450 1A1 (CYP1A1) gene codes for an enzyme that contributes to aryl hydrocarbon hydroxylase activity, which is involved in the metabolism of polyaromatic hydrocarbons. Genotypic variants of CYP1A1 have been associated with increased aryl hydrocarbon hydroxylase activity, and some epidemiological studies suggest that women with the variant genotype(s) are at increased risk for breast cancer.. We prospectively evaluated the associations between the CYP1A1 polymorphisms and breast cancer risk, as well as the potential modification of these associations by cigarette smoking, in a case-control study nested within the Nurses Health Study. We analyzed the T→C transition ...

Yahya Jammeh aliyetawala Gambia kwa miaka 22, anatuhumiwa kuwakandamiza wapizani na kutumia utesaji na ukatili wa kutisha dhidi ya waandamanaji na wanasiasa waliokuwa wakimkosoa. Suala hilo lilishika kasi hasa katika kipindi cha kampeni za uchaguzi wa rais uliopita, ambapo akthari ya viongozi wa vyama mbalimbali vya siasa na wapinzani dhidi ya serikali walitiwa mbaroni nchini. Hata baadhi ya weledi wa mambo waliutaja ushindi wa Adama Barrow kuwa uliotokana na natija ya vitendo hivyo vya serikali iliyopita. Kwa kuwa na idara ya usalama wa taifa yenye nguvu, Jammeh aliweza kuwakandamiza wapinzani na waandamanaji nchini Gambia ambapo alizuia kila aina ya maandamano na mikusanyiko ya wapinzani. Siku chache zilizopita, naibu mkuu wa shirika la kutetea haki za binaadamu la Human Rights Watch anayeshughulikia masuala ya mipango ya shirika hilo alitoa ripoti iliyoeleza kwamba, serikali ya Jammeh ilikuwa ikitumia vitisho na utesaji dhidi ya viongozi wa vyama vya upinzani na kuwanyima haki zao za msingi. ...

Aidha wameshauri kuchukuliwa hatua kwa baadhi ya vyama vya siasa vinavyofanya siasa za udini kwa kuhusisha viongozi wa dini katika kampeni zao, huku vikitambua kuwa ni kinyume cha Katiba ya nchi na Sheria ya Vyama vya siasa..

1. [3H]Benzo(a)pyrene and 6-substituted derivatives of [3H]benzo(a)pyrene are covalently bound to calf thymus DNA upon reaction with microsomal preparations from rats pretreated with 3-methylcholanthrene in the presence of NADPH. Two different types of cytochrome P-450-448 inhibitors, alpha-naphthoflavone and 1-benzylimidazole, show greater than 80% inhibition of the binding of benzo(a)pyrene to DNA. 2. In the presence of these inhibitors, 6-hydroxymethylbenzo(a)pyrene, 6-methylbenzo(a)pyrene and 6-formylbenzo(a)pyrene show varying degrees of inhibition of binding to DNA depending upon the inhibitor employed. 3. Polyguanylic acid is the most effective substrate for the binding of each activated polynuclear aromatic hydrocarbon; polyadenylic acid and DNA show essentially equivalent binding. ...
