Congenital erythropoietic porphyria in an African hedgehog (Atelerix albiventris).     

Carlos Wolff  Paulina Corradini  Galaxia Cortés 《Journal of zoo and wildlife medicine》2005,36(2):323-325

A 6-mo-old, male African hedgehog (Atelerix albiventris) presented with a history of pink urine and demonstrating pink-colored teeth and mild hepatomegaly on examination. Urinalysis revealed no physical, chemical, or cellular abnormalities other than a pink color and fluorescence under ultraviolet light (UV). Also under UV, intense fluorescence of teeth, feet, and spines was noted. Porphyria was suspected. Spectrophotometric evaluation of urine showed extremely elevated levels of copro- and uroporphyrins. Analysis of the urine by thin-layer chromatography showed an abnormal pattern of excreted porphyrin intermediates. Urine high-performance thin-layer chromatography showed that excreted porphyrins were 90-95% of the type-I isomeric form, suggestive of congenital erythropoietic porphyria.  相似文献

The impact of climate on radial growth and nut production of Persian walnut (<Emphasis Type="Italic">Juglans regia</Emphasis> L.) in Southern Kyrgyzstan

This dendroecological study used time series of climate and radial growth and nut production of Juglans regia to investigate the relationships between these parameters. More than 200 trees growing at sites of different altitude, aspect, inclination and human impact intensity were sampled in walnut-fruit forests of the Jalal Abad region in Southern Kyrgyzstan. Tree rings were dated and ring widths measured. Wide and narrow tree rings, so called positive and negative pointer years, could be explained by climatic events. The mean annual increment differed significantly in different regions and altitudes. The highest values could be found in plantations and at higher altitudes (1,700–2,000 m a.s.l.). Analysing the relationships between nut crop yields and annual increment, we found a significantly positive correlation between nut crop of the current year (x) and ring width of the previous year (x − 1). This relationship is influenced by climatic conditions, and may change in the future if climatic conditions in the region will change. Our study shows that Persian walnut (Juglans regia L.) of South Kyrgyzstan can be used in dendrochronological studies, and illustrates the influence of site conditions and management practices on radial growth of this tree species.  相似文献   

Management of the Peruvian bay scallop (Argopecten purpuratus) metapopulation with regard to environmental change     

Matthias Wolff  Jaime Mendo 《水产资源保护:海洋与淡水生态系统》2000,10(2):117-126

1. This paper sets out to: (1) review previous ecological studies and analyse recent trends of the Peruvian bay scallop fishery in order to better understand and to model the species’ temporal and spatial (meta) population dynamics along the South Pacific coast; (2) develop a fisheries model to protect the stock from overexploitation and optimize the annual yield of the pulse fishery in Independence Bay, the centre of the scallop diving fishery in Peru. 2. Natural stock fluctuations are very pronounced in this species and are positively correlated with the El Niño–Southern Oscillation (ENSO). During such an event, habitat conditions for the Peruvian bay scallop are improved either regionally or locally, such that populations proliferate and larval production and dispersal are greatly increased. Extinct beds and new habitats are recolonized during these periods (producing a strong pulse of metapopulation biomass), although most become extinct very shortly thereafter. 3. For management purposes, two considerations are fundamental: (1) heavy overfishing or extinction of the main scallop source populations would endanger the metapopulation as a whole; (2) rates of growth and survival greatly increase (and with them the potential yield of the scallop stock) locally over an El Niño cycle in a way that can be roughly estimated from past experience, including the most recent El Niño event (1997–1998). 4. We suggest a fisheries management regime capable of adapting to natural changes and propose a procedure for calculating both the optimal yield and the respective fishing effort under normal upwelling and El Niño scenarios, considering changes in the size at first capture (Lc) and fishery mortality (F).

Identification of flavonoids and hydroxycinnamic acids in pak choi varieties (Brassica campestris L. ssp. chinensis var. communis) by HPLC-ESI-MSn and NMR and their quantification by HPLC-DAD

Twenty-eight polyphenols (11 flavonoid derivatives and 17 hydroxycinnamic acid derivatives) were detected in different cultivars of the Chinese cabbage pak choi ( Brassica campestris L. ssp. chinensis var. communis) by HPLC-DAD-ESI-MS(n). Kaempferol was found to be the major flavonoid in pak choi, glycosylated and acylated with different compounds. Smaller amounts of isorhamnetin were also detected. A structural determination was carried out by (1)H and (13)C NMR spectroscopy for the main compound, kaempferol-3-O-hydroxyferuloylsophoroside-7-O-glucoside, for the first time. Hydroxycinnamic acid derivatives were identified as different esters of quinic acid, glycosides, and malic acid. The latter ones are described for the first time in cabbages. The content of polyphenols was determined in 11 cultivars of pak choi, with higher concentrations present in the leaf blade than in the leaf stem. Hydroxycinnamic acid esters, particularly malic acid derivatives, are present in both the leaf blade and leaf stem, whereas flavonoid levels were determined only in the leaf blade.  相似文献
