Bibliography: 140-161 leaves .<br>Porphyra (Bangiales, Rhodophyta) is the world's most valuable maricultured seaweed, due to its high value as a food crop. The vast majority of Porphyra in South Africa belongs to P. capensis, a morphologically and ecologically plastic taxon apparently endemic to the region. There is no demand for P. capensis as a food crop, as it is unsuitable for the market, and there are no records of its customary use locally. Porphyra capensis is however a potentially highly valuable fodder for the mariculture of abalone (Haliotis midae), and pressure to harvest it has rec

Abstract:

The intertidal red algal genus Porphyra is found on rocky shores worldwide. In the Northern Hemisphere the genus is well studied but there is a paucity of data on southern hemisphere Porphyra and even less on New Zealand Porphyra. The species� taxonomy has been undergoing revision since the late 1990�s, when it was discovered that the main species P. columbina and P. lilliputana reported for New Zealand were a combination of several endemic species. These species are found from the low to the high intertidal watermark; hence they are exposed to fluctuating stresses such as desiccation, tempera

The oceans represent a wealth of biological diversity where many species remain to be discovered and described.

Abstract:

Porphyrias are a group of inherited metabolic disorders of heme biosynthesis. Each porphyria derives from an alteration in the heme biosynthetic pathway resulting in a specific accumulation of heme precursors. These rare diseases are characterized by an extended heterogeneity of mutations affecting the coding region of the genes directly or indirectly involved in the pathway. In this study, we assessed three new variants identified in the regulatory regions of the PPOX gene using human hepatocarcinoma (Hep3B) and erythroleukemia (K562) cell lines. We demonstrated a lower expression of the PPOX

Intraperitoneal administration of 3,5-diethoxy-carbonyl-1,4-dihydrocollidine (DDC) to female C3H/He/01a and NIH/01a inbred mice produced a marked dose-dependent loss of hepatic ferrochelatase (FK) activity, induction of g-aminolaevulinic acid synthetase (ALA-S) and accumulation of protoporphyrin. There was no strain difference in the degree of FK inhibition. However, induction of ALA-S was greater in C3H/He/01a mice. The strain difference in ALA-S response was most marked when inhibition of FK (the "specific" effect of DDC) was maximal and this suggests that a genetic variation exists in the s

The porphyrias are a group of disorder resulting from defects in the haem biosynthesis pathway. The majority of defects are genetic in origin.

It is therefore likely that genetic modifiers are present to influence the phenotypic outcome of the disease.

Abstract:

The Dinkidi Cu-Au porphyry deposit is located in northern Luzon, Philippines. The 110 Mt deposit is characterised by high gold grades (ave. 1.2 g/t Au and 0.5% Cu) and is one of only a few alkaline porphyry deposits to have been discovered outside British Columbia. Alkaline magmatism in northern Luzon is related to the Late Oligocene rifting event that formed the Cagayan Valley Basin, and to the final stages of west-directed subduction along the East Luzon trench. Subalkaline andesitic and trachytic lavas and minor volcaniclastic rocks of the Mamparang Formation were emplaced along the southw

Selon l’hypothèse des éditeurs Grégoire et Kugener, la Vie actuelle est le fruit du remaniement d’un texte plus ancien. Le texte no

Abstract:

Notre thèse en deux volumes vise à donner une traduction inédite du premier commentaire de Boèce à l’Isagogè de Porphyre à partir de l’édition critique de Samuel Brandt publiée en 1906. De fait, Boèce s’appuie sur la traduction latine de Marius Victorinus et non, comme le suggère le titre, sur le texte grec de Porphyre. Le premier volume contient une introduction générale articulée en quatre parties: examen critique des études secondaires; les sources matérielles du premier commentaire de Boèce à l’Isagogè; le traitement des questions de Porphyre sur les universaux; et l’Isagogè de Marius Vict
