The kidney as a novel target tissue for protein adduct formation associated with metabolism of halothane and the candidate chlorofluorocarbon replacement 2,2-dichloro-1,1,1-trifluoroethane. (1/7)
Hydrochlorofluorocarbons (HCFCs) have been identified as chemical replacements of the widely used chlorofluorocarbons (CFCs) that are implicated in stratospheric ozone depletion. Many HCFCs are structural analogues of the anesthetic agent halothane and may follow a common pathway of biotransformation and formation of adducts to protein-centered and other cellular nucleophiles. Exposure of rats to a single dose of halothane (2-bromo-2-chloro-1,1,1-trifluoroethane) or of the candidate CFC substitute HCFC 123 (2,2-dichloro-1,1,1-trifluoroethane) led to the formation of trifluoroacetylated protein adducts (CF3CO-proteins) not only in the liver, but also in the kidney as a novel target tissue for protein trifluoroacetylation. CF3CO-proteins in the kidney amounted to about 5% of those formed in the liver of the same animal. The amount of CF3CO-proteins formed within the kidney was roughly reflected by the capacity of metabolism of halothane or HCFC 123 by rat kidney microsomes in vitro which amounted to about 10% of that observed with liver microsomes. By immunohistochemistry, CF3CO-proteins in the kidney were mainly localized in the tubular segments of the cortex. In the liver, the density of CF3CO-proteins decreased from the central vein towards the portal triad. In vitro incubation of rat liver microsomes with halothane or HCFC 123 resulted in extensive formation of CF3CO-proteins and reproduced faithfully the pattern of liver CF3CO-proteins obtained in vivo. CF3CO-proteins generated in vitro were immunochemically not discernible from those generated in vivo. Glutathione (5 mM) and cysteine (5 mM) virtually abolished CF3CO-protein formation; the release of Br- from halothane and Cl- from HCFC 123 was reduced to much lesser a degree. S-Methyl-glutathione, N-acetyl-cysteine, methionine, and N-acetyl-methionine only slightly affected the formation of CF3CO-proteins or metabolism of either substrate. The data suggest that metabolism and concomitant CF3CO-protein formation of halothane or of candidate CFC replacements like HCFC 123 is not restricted to the liver but also takes place in the kidney. Furthermore, an in vitro system for CF3CO-protein formation has been developed and used to show that protein-centered and glutathione-centered nucleophilic sites compete for intermediates of metabolism of halothane or of HCFC 123.

Hydrochlorofluorocarbons (HCFCs) are being developed as substitutes for ozone-depleting chlorofluorocarbons (CFCs); because widespread human exposure to HCFCs may be expected, it is important to evaluate their toxicities thoroughly. Here we report studies on the bioactivation of the CFC substitute 2,2-dichloro-1,1,1-trifluoroethane (HCFC-123) to an electrophilic intermediate that reacts covalently with liver proteins. HCFC-123 and its analog halothane (2-bromo-2-chloro-1,1,1-trifluoroethane) were studied in rats by 19F NMR spectroscopy, and we found that a trifluoroacetylated lysine adduct was formed with liver proteins. Also, the pattern of proteins immunoreactive with hapten-specific anti-trifluoroacetylprotein antibodies was identical in livers of HCFC-123- and halothane-exposed rats. Because halothane causes an idiosyncratic, and sometimes fatal, hepatitis that is associated with an immune response against several trifluoroacetylated liver proteins, the present findings raise the possibility that humans exposed to HCFC-123 or structurally related HCFCs may be at risk of developing an immunologically mediated hepatitis.

Chloroform and ether commonly are used as solvents to extract metabolic organic acids for analysis by gas-liquid chromatography in the identification of anaerobic bacteria. Because these solvents are potentially hazardous to personnel, modified extraction procedures involving the use of a safer solvent, methyl tert-butyl ether were developed which remained both simple to perform and effective for organism identification.

Groups of 10 male Hartley guinea pigs were exposed to 3.0, 2.0, 1.0, or 0.1% (v/v) 1,1-Dichloro-2,2,2-trifluoroethane (HCFC-123) or 1.0% (v/v) halothane by inhalation for 4 hr. A sixth group of 10 guinea pigs received only air. All animals were sacrificed 48 hr postexposure. Gross and histopathologic examination of the liver, heart, and kidney and routine hematology and clinical chemistry analyses [including isocitrate dehydrogenase (ICDH)] were done on all guinea pigs. Lesions related to HCFC-123 and halothane exposure were limited to the liver and included centrolobular vacuolar (fatty) change, multifocal random degeneration and necrosis, and centrolobular degeneration and necrosis. These lesions were observed in 90-100% of the exposed animals and were absent in the air-only controls. There was significant individual animal variation in susceptibility to both HCFC-123 and halothane, resulting in a spectrum of histologic lesions and clinical chemistry values within each exposure group. Alanine aminotransferase, aspartate aminotransferase, and ICDH were the most significant predictors of hepatocellular damage. Similarities in the response between halothane and HCFC-123 in this guinea pig model suggests that humans susceptible to halothane-induced hepatitis may be susceptible to HCFC-123 by a common mechanism of toxicity.

The ability of microorganisms to degrade trace levels of the hydrochlorofluorocarbons HCFC-21 and HCFC-123 was investigated. Methanotroph-linked oxidation of HCFC-21 was observed in aerobic soils, and anaerobic degradation of HCFC-21 occurred in freshwater and salt marsh sediments. Microbial degradation of HCFC-123 was observed in anoxic freshwater and salt marsh sediments, and the recovery of 1,1,1-trifluoro-2-chloroethane indicated the involvement of reductive dechlorination. No degradation of HCFC-123 was observed in aerobic soils. In some experiments, HCFCs were degraded at low (parts per billion) concentrations, raising the possibility that bacteria in nature remove HCFCs from the atmosphere. (+info)Toxicology of chlorofluorocarbon replacements. (6/7)
Chlorofluorocarbons (CFCs) are stable in the atmosphere and may reach the stratosphere. They are cleaved by UV-radiation in the stratosphere to yield chlorine radicals, which are thought to interfere with the catalytic cycle of ozone formation and destruction and deplete stratospheric ozone concentrations. Due to potential adverse health effects of ozone depletion, chlorofluorocarbon replacements with much lower or absent ozone depleting potential are developed. The toxicology of these compounds that represent chlorofluorohydrocarbons (HCFCs) or fluorohydrocarbons (HFCs) has been intensively studied. All compounds investigated (1, 1-dichloro-1-fluoroethane [HCFC-141b], 1,1,1,2-tetrafluoroethane [HFC-134a], pentafluoroethane [HFC-125], 1-chloro- 1,2,2,2-tetrafluoroethane [HCFC-124], and 1,1-dichloro-2,2,2-trifluoroethane [HCFC-123]) show only a low potential for skin and eye irritation. Chronic adverse effects on the liver (HCFC-123) and the testes (HCFC-141b and HCFC-134a), including tumor formation, were observed in long-term inhalation studies in rodents using very high concentrations of these CFC replacements. All CFC replacements are, to varying extents, biotransformed in the organism, mainly by cytochrome P450-catalyzed oxidation of C-H bonds. The formed acyl halides are hydrolyzed to give excretable carboxylic acids; halogenated aldehydes that are formed may be further oxidized to halogenated carboxylic acids or reduced to halogenated alcohols, which are excretory metabolites in urine from rodents exposed experimentally to CFC replacements. The chronic toxicity of the CFC replacements studied is unlikely to be of relevance for humans exposed during production and application of CFC replacements.

Human subjects were exposed by inhalation to 250, 500, and 1000 ppm 1,1-dichloro-1-fluoroethane (HCFC-141b) for 4 hr, and urine samples were collected from 0-4, 4-12, and 12-24 hr for metabolite analysis. 19F nuclear magnetic resonance spectroscopic analysis of urine samples from exposed subjects showed that 2,2-dichloro-2-fluoroethyl glucuronide and dichlorofluoroacetic acid were the major and minor metabolites, respectively, of HCFC-141b. Urinary 2, 2-dichloro-2-fluoroethyl glucuronide was hydrolyzed to 2, 2-dichloro-2-fluoroethanol by incubation with beta-glucuronidase, and the released 2,2-dichloro-2-fluoroethanol was quantified by gas chromatography/mass spectrometry. Concentrations of 2, 2-dichloro-2-fluoroethanol were highest in the urine samples collected 4-12 hr after exposure, but 2,2-dichloro-2-fluoroethanol was also detected in the samples collected 0-4 and 12-24 hr after exposure. Exposure concentration-dependent excretion of 2, 2-dichloro-2-fluoroethanol, obtained by hydrolysis of 2, 2-dichloro-2-fluoroethyl glucuronide, was observed in seven of the eight subjects studied. In conclusion, HCFC-141b is metabolized in human subjects to 2,2-dichloro-2-fluoroethanol, which is conjugated with glucuronic acid and excreted as its glucuronide in urine in a time- and exposure concentration-dependent manner.

Dewoitine D.371
The Dewoitine 37 was the first of a family of 1930s French-built monoplane fighter aircraft. The D.37 was a single-seat aircraft of conventional configuration. Its fixed landing gear used a tailskid. The open cockpit was located slightly aft of the parasol wing. The radial engine allowed for a comparatively wide fuselage and cockpit. Design of this machine was by SAF-Avions Dewoitine but owing to over work at that companies plant at the time, manufacture of the D.37/01 was transferred to Lioré et Olivier. They were high-wing monoplanes of all-metal construction with valve head blisters on their engine cowlings. The first prototype flew in October 1931. Flight testing resulted in the need for multiple revisions in both engine and airframe, so it was February 1934 before the second prototype flew. Its performance prompted the French government to order for 28 for the Armée de l'Air and Aéronavale. The Lithuanian government ordered 14 that remained in service with their Air Force until 1936, ...
Noor-ul-Ain
The Noor-ul-Ain (Persian: نور العين, lit. 'the light of the eye') is one of the largest pink diamonds in the world, and the centre piece of the tiara of the same name. The diamond is believed to have been recovered from the mines of Golconda, Hyderabad in India. It was first in possession with the nizam Abul Hasan Qutb Shah, later it was given as a peace offering to the Mughal emperor Aurangazeb when he defeated him in a siege. It was brought into the Iranian Imperial collection after the Persian king Nader Shah Afshar looted Delhi in the 18th century.[citation needed] The Noor-ul-Ain is believed to have once formed part of an even larger gem called the Great Table diamond. That larger diamond is thought to have been cut in two, with one section becoming the Noor-ul-Ain and the other the Daria-i-Noor diamond. Both of these pieces are currently part of the Iranian Crown Jewels. The Noor-ul-Ain is the principal diamond mounted in a tiara of the same name made for Iranian Empress Farah ...
Benoist Land Tractor Type XII
The Benoist Land Tractor Type XII was one of the first enclosed cockpit, tractor configuration aircraft built. Benoist used "Model XII" to several aircraft that shared the same basic engine and wing design, but differed in fuselage and control surfaces. The Type XII was a tractor-engined conversion of the model XII headless pusher aircraft that resembled the Curtiss pusher aircraft. Demonstration pilots used Benoist aircraft to demonstrate the first parachute jumps, and the tractor configuration was considered much more suitable for the task. The first example named the "Military Plane" had a small box frame covered fuselage that left the occupants mostly exposed to the wind. The later model XII "Cross Country Plane" had a full fuselage that occupants sat inside of. The first tractor biplane used a wooden fuselage with a small seat on top. The wings were covered with a Goodyear rubberized cloth. The first model XII was built in the spring of 1912. On 1 March 1912, Albert Berry used a headless ...

We, Too, Have a Job to Do
... is a painting by American illustrator Norman Rockwell that depicts a Boy Scout in full uniform standing in front of a waving American flag. It was originally created by Rockwell in 1942 for the 1944 Brown & Bigelow Boy Scout Calendar. The model, Bob Hamilton, won a contest to be in the painting and personally delivered a print to the Vice President of the United States at the time, Henry A. Wallace. The painting was created to encourage Scouts to participate in the war effort during World War II. The name of the painting, We, Too, Have a Job to Do, comes from a slogan that the Boy Scouts of America used in 1942 to rally scouts to support the troops by collecting metal and planting victory gardens. The model, Bob Hamilton, won a contest with his local council in Albany, New York, to be depicted in the painting. He traveled to Rockwell's studio in Arlington, Vermont, to model for Rockwell. Since Hamilton was a scout, the uniform shown in the painting was his, unlike some ...

Sestiere
A sestiere (plural: sestieri) is a subdivision of certain Italian towns and cities. The word is from sesto ('sixth'), so it is thus used only for towns divided into six districts. The best-known example is the sestieri of Venice, but Ascoli Piceno, Genoa, Milan and Rapallo, for example, were also divided into sestieri. The medieval Lordship of Negroponte, on the island of Euboea, was also at times divided into six districts, each with a separate ruler, through the arbitration of Venice, which were known as sestieri. The island of Crete, a Venetian colony (the "Kingdom of Candia") from the Fourth Crusade, was also divided into six parts, named after the sestieri of Venice herself, while the capital Candia retained the status of a comune of Venice. The island of Burano north of Venice is also subdivided into sestieri. A variation of the word is occasionally found: the comune of Leonessa, for example, is divided into sesti or sixths. Other Italian towns with fewer than six official districts are ...
Island Image
The Island Image is a Chesapeake Bay log canoe, built in 1885 at Elliot's Island, Maryland, by Herman Jones and Isaac Moore. She is 29'-8½" long with a beam of 5-10¼", and has a straight, raking stem and a sharp stern. It is privately owned, and races under No. 17. She one of the last 22 surviving traditional Chesapeake Bay racing log canoes that carry on a tradition of racing on the Eastern Shore of Maryland that has existed since the 1840s. She is located at Chestertown, Kent County, Maryland. She was listed on the National Register of Historic Places in 1985. "National Register Information System". National Register of Historic Places.
