Abstract:
ZusammenfassungPorphyrien werden durch Enzymdefekte der Hämbiosynthese hervorgerufen und anhand spezifischer biochemischer Muster von Porphyrinen und deren Vorläufern in Urin, Stuhl und Blut diagnostiziert. Das jeweilige Muster der akkumulierten Porphyrine, Vorläufer und Derivate ist verbunden mit der klinischen Ausprägung, die abdominale, neurologische, psychiatrische, endokrine, kardiovaskuläre Symptome, Leberschaden und/oder Lichtempfindlichkeit der Haut umfassen kann. Klinisch werden akute und nichtakute Porphyrien unterschieden. Bei symptomatischen (klinisch aktiven), akuten hepatischen Porphyrien – hierzu gehören akute intermittierende Porphyrie, Porphyria variegata, hereditäre Koproporphyrie und Doss-Porphyrie – kommt es aufgrund einer Regulationsstörung zur Kumulation der Porphyrinvorläufer 5‑Aminolävulinsäure und Porphobilinogen. Bei den nichtakuten Formen – u. a. Porphyria cutanea tarda, erythropoetische und X‑chromosomale Protoporphyrie sowie kongenitale erythropoetische Porphyrie – führen akkumulierte Porphyrine zu Lichtempfindlichkeit (Fotodermatose) und mitunter auch zu schweren Leberschäden. Zur Therapie der Porphyrien stehen sowohl bewährte und sichere als auch innovative Optionen zur Verfügung.

Abstract:
The phylogenetic relationships of a number of flightless and volant rails have been investigated using mtDNA sequence data. The third domain of the small ribosomal subunit (12S) has been sequenced for 22 taxa, and part of the 5′ end of the cytochrome– b gene has been sequenced for 12 taxa. Additional sequences were obtained from outgroup taxa, two species of jacana, sarus crane, spur–winged plover and kagu. Extinct rails were investigated using DNA extracted from subfossil bones, and in cases where fresh material could not be obtained from other extant taxa, feathers and museum skins were used as sources of DNA. Phylogenetic trees produced from these data have topologies that are, in general, consistent with data from DNA–DNA hybridization studies and recent interpretations based on morphology. Gallinula chloropus (moorhen) groups basally with Fulica (coots), Amaurornis (= Megacrex ) ineptus falls within the Gallirallus/Rallus group, and Gallinula (= Porphyrula ) martinica is basal to Porphyrio (swamphens) and should probably be placed in that genus. Subspecies of Porphyrio porphyrio are paraphyletic with respect to Porphyrio mantelli (takahe). The Northern Hemisphere Rallus aquaticus is basal to the south–western Pacific Rallus (or Gallirallus ) group. The flightless Rallus philippensis dieffenbachii is close to Rallus modestus and distinct from the volant Rallus philippensis , and is evidently a seperate species. Porzana (crakes) appears to be more closely associated with Porphyrio than Rallus . Deep relationships among the rails remain poorly resolved. Rhynochetos jubatus (kagu) is closer to the cranes than the rails in this analysis. Genetic distances between flightless rails and their volant counterparts varied considerably with observed 12S sequence distances, ranging from 0.3 % ( Porphyrio porphyrio melanotus and P. mantelli mantelli ) to 7.6 % ( Rallus modestus and Rallus philippensis ). This may be taken as an indication of the rapidity with which flightlessness can evolve, and of the persistence of flightless taxa. Genetic data supported the notion that flightless taxa were independently derived, sometimes from similar colonizing ancestors. The morphology of flightless rails is apparently frequently dominated by evolutionary parallelism although similarity of external appearance is not an indication of the extent of genetic divergence. In some cases, taxa that are genetically close are morphologically distinct from one another (e.g. Rallus (philippensis) dieffenbachii and R. modestus ), whilst some morphologically similar taxa are evidently independently derived (e.g. Porphyio mantelli hochstetteri and P. m. mantelli ).

Abstract:
Our knowledge of the historical use of nonhuman animal species in captivity and subsequent human-induced changes in their distribution is poor in comparison to contemporary case studies. Here we assess the hypothesis that, in the case of one waterbird species, the purple swamphen or gallinule (Porphyrio porphyrio), we have neglected the high probability that people transported these birds within the Mediterranean, from Roman to recent times. In ancient iconographies, literary sources, and more recent records there is ample evidence for the use of this species in captivity, captive-breeding, and for trade during several historical periods, especially within the Mediterranean region. All this evidence supports the hypothesis that released or escaped birds might have hybridized with other populations living in the wild. This case study stresses the importance of taking into account past human activity when interpreting contemporary distributional patterns of species.

Abstract:
Abstract Background: As an aid in the diagnosis and management of porphyria we have developed a method to fractionate and quantify plasma porphyrins and have evaluated its use in various porphyrias. Methods: We used HPLC with fluorometric detection to measure plasma concentrations of uroporphyrin I and III, heptacarboxyl III, hexacarboxyl III, pentacarboxyl III, and coproporphyrin I and III. We studied 245 healthy subjects, 32 patients with classical porphyria cutanea tarda (PCT), 12 patients with PCT of renal failure, 13 patients with renal failure, 8 patients with pseudoporphyria of renal failure, 3 patients with acute intermittent porphyria, 5 patients with variegate porphyria, 5 patients with hereditary coproporphyria, and 4 patients with erythropoietic protoporphyria. Results: Between-run CVs were 5.4–13%. The recoveries of porphyrins added to plasma were 71–114% except for protoporphyrin, which could not be reliably measured with this technique. Plasma porphyrin patterns clearly identified PCT, and its clinical sensitivity equaled that of urine porphyrin fractionation. The patterns also allowed differentiation of PCT of renal failure from pseudoporphyria of renal failure. Conclusions: The assay of plasma porphyrins identifies patients with PCT and appears particularly useful for differentiating PCT of renal failure from pseudoporphyria of renal failure.

Abstract:
Hepatic porphyries have been associated with an increased risk of primary liver cancer (PLC), which on the other hand may cause an increased porphyrin production. To evaluate the role of an underlying liver disorder we analyzed porphyrins in patients with hepatocellular carcinoma (HCC)(n=65), cholangiocellular carcinoma(n=3), or suspected PLC, which turned out to be metastases(n=18)or a benign disorder(n=11). None of the patients had a family history of porphyry or clinical signs of porphyry. Increased aminolevulinic acid or porphyrin values were common not only in patients with PLC (43%) but also in metastatic (50%) and benign (64%) liver disorders. The corresponding proportion for HCC patients with liver cirrhosis (55%) was higher(P<.05)than in those without cirrhosis (17%). We conclude that symptomatic porphyries are unusual in PLC, whereas elevated urinary and/or faecal porphyrins are common, primarily reflecting a parallel liver disease and not the PLC.

Abstract:
Details are presented of gonad parameters and reproductive status, body measurements, moult, and food taken by purple swamphens collected in the Gippsland Lakes area between July 1971 and July 1973. Information from other studies is also discussed. Plant material (76% estimated average volume) dominated gizzard contents, particularly when inorganic material (23%) was discounted, and animal remains (c. 1%) were found in only 51 of the 234 gizzards with food examined. Mostly semi-aquatic plants were eaten, predominantly from Gramineae (59%), Cyperaceae (17%) and Hydrocharitaceae (11%), and Phragrnites australzs was the main species identified. The proportion of roots, rhizomes and tubers in gizzards increased in autumn samples. Monthly variations in the grit content of gizzards were significant; males (which were larger than females) held more large-sized fragments than females, and there was a moderate negative correlation between hard seeds and grit. Ovarian follicles were generally largest between July and November and seminiferous tubule diameters in males increased from June and July to reach a maximum from September to November; sperm were present from July to November. There were no simple correlations between gonad parameters and local rainfall in the preceding 30 days. The presence of a bursa of Fabricius did not successfully exclude reproductively active birds, but male swamphens with cloaca1 papillae and no bursa had larger testes than those with a bursa but no papillae. Colour scores for bill and tarsus showed some seasonal variation in subsamples of males and females. Management of wetlands for this species must take account of its requirement for a relatively restricted range of food types.

Abstract:
Porphyrias are distinguished by the stage of heme synthesis at which a failure occurs, leading to the accumulation of intermediate products – porphyrins. Due to the low specificity of clinical manifestations of porphyria and the latent course of the disease, their timely diagnosis is difficult. This article substantiates the effectiveness of high-performance liquid chromatography method in the determination of porphyrins. The method is suitable for porphyrin determination in urine, blood and feces of patients. Examples of its work are shown.

Abstract:
The porphyrias are disorders of haem biosynthesis which present with acute neurovisceral attacks or disorders of sun-exposed skin. Acute attacks occur mainly in adults and comprise severe abdominal pain, nausea, vomiting, autonomic disturbance, central nervous system involvement and peripheral motor neuropathy. Cutaneous porphyrias can be acute or chronic presenting at various ages. Timely diagnosis depends on clinical suspicion leading to referral of appropriate samples for screening by reliable biochemical methods. All samples should be protected from light. Investigation for an acute attack: • Porphobilinogen (PBG) quantitation in a random urine sample collected during symptoms. Urine concentration must be assessed by measuring creatinine, and a repeat requested if urine creatinine <2 mmol/L. • Urgent porphobilinogen testing should be available within 24 h of sample receipt at the local laboratory. Urine porphyrin excretion (TUP) should subsequently be measured on this urine. • Urine porphobilinogen should be measured using a validated quantitative ion-exchange resin-based method or LC-MS. • Increased urine porphobilinogen excretion requires confirmatory testing and clinical advice from the National Acute Porphyria Service. • Identification of individual acute porphyrias requires analysis of urine, plasma and faecal porphyrins. Investigation for cutaneous porphyria: • An EDTA blood sample for plasma porphyrin fluorescence emission spectroscopy and random urine sample for TUP. • Whole blood for porphyrin analysis is essential to identify protoporphyria. • Faeces need only be collected, if first-line tests are positive or if clinical symptoms persist. Investigation for latent porphyria or family history: • Contact a specialist porphyria laboratory for advice. Clinical, family details are usually required.

Abstract:
Meso-hydroxyuroporphyrin I, B-hydroxypropionic acid uroporphyrin I, hydroxyacetic acid uroporphyrin I and peroxyacetic acid uroporphyrin I have been isolated from the urine and plasma of patients with congenital erythropoietic porphyria (CEP) by high-performance liquid chromatography and characterized by liquid secondary ion mass spectrometry and chemical properties. The physico-chemical properties of these compounds have been studied. The hydroxy- and peroxyacetic acid- uroporphyrin I derivatives are the true metabolites of uroporphyrinogen I in vivo and their presence in urine and plasma is a common feature of CEP. The absence of these derivatives in duodenal aspirate and faeces suggests that they are of erythropoietic origin. The mechanism of formation of the hydroxy- and peroxyacetic acid- uroporphyrin I has been investigated. Peroxyacetic acid uroporphyrin I is formed from uroporphyrinogen I in the presence of H202 and iron while the hydroxylated uroporphyrin I derivatives are most probably produced by hydroxyl radicals generated during the formation of peroxyacetic acid uroporphyrin I. Destruction of porphyrins is found in the same reaction and can be prevented bydesferrioxamine, indicating that it is due to hydroxyl radicals. The formation of peroxyacetic acid- and hydroxyuroporphyrin I derivatives are uroporphyrinogen I concentration dependent. These derivatives can only be formed when uroporphyrinogen I is accumulated to a certain concentration (approx. 1-2 ~M) and the formation is then proportional to the uroporphyrinogen I concentration. The peroxylation reaction has been shown to take place only at the acetic acid side-chains of porphyrinogen and not at the propionic acid side-chains. The peroxylation reaction can therefore take place whenever a porphyrinogen with an acetic acid substituent is accumulated. Oral charcoal therapy failed to reduce the porphyrins accumulated in vivo in a patient with CEP. Uroporphyrin I, the major porphyrin accumulating in CEP, was not excreted into bile and interruption of the enterohepatic circulation by binding porphyrins onto charcoal therefore does not benefit CEP. It may, however, be effective in the treatment of hepatic porphyrias in which the accumulated porphyrins are mainly excreted via the gut lumen.

Abstract:
Current biological sensing technologies of bacteria are time consuming, labor intensive and thus expensive. Furthermore, their accuracy and reproducibility could be improved. Conventional electrical measurement methods might combine high sensitive sensing systems with biological requirements. A promising approach is the trapping of bacteria on the surface of the gate-electrode of a modified field-effect transistor (FET) using porphyin based self-assembled monolayers (SAMs). 5,15-A2BC-type porphyrins were synthesized originating from a 5,15-diphenylporphyrin with the functionality to connect to a gold surface. The SAM formation on the surface of the gold electrode was proven by well-established analytical methods. In this work a synthesis route is presented for a linker which is attached to a peptide or cysteine group for trapping of Gram-negative bacteria. Fluorescence lifetime imaging microscopy (FLIM) measurements of porphyrin-stained bacteria were performed to verify the linkage ability.
