Phytochemical investigation from the stems of Alibertia edulis led to the isolation and identification of a new iridoid 6β‐hydroxy‐7‐epigardoside methyl ester ( 1 ) and a new saponin 3β‐O‐[α‐L ‐rhamnopyranosyl‐(1→2)‐O‐β‐D ‐glucopyranosyl‐(1→2)‐O‐β‐D ‐glucopyranosyl]‐28‐O‐β‐D ‐glucopyranoside pomolate ( 2 ), along with three known compounds, shanzhiside methyl ester ( 3 ), ixoside ( 4 ), and 3,4,5‐trimethoxyphenyl 1‐O‐β‐D ‐apiofuranosyl‐(1→6)‐O‐β‐D ‐glucopyranoside ( 5 ). The structures of 1 and 2 were established on the basis of their spectroscopic data. Iridoid 1 and saponin 2 exhibited moderate inhibitory activities against Candida albicans and C. krusei in a dilution assay. 相似文献

The majority of visual impairments are related to retinal disorders. Therefore, techniques useful for early detection of retinal
anomalies are of great interest for diagnosis and treatment of related pathologies. Optical Coherence Tomography (OCT) is
a non-invasive technique that is becoming increasingly important in the analysis of human retina. This technique produces
sections of a three dimensional reflectance map, which are pseudo-images of the retinal structure. In these pseudo-images,
early pathologies may produce local modifications of reflectance, which visually, appear as blots. Consequently, automatic
procedures for detection of such blots may be of help in the diagnosis of many retinal diseases. Due to the complexity of
the measurement technique and of the retinal structure, the pseudo-images produced by OCT can be modeled as 2D random signals:
the above pathological blots correspond to sudden changes in the distribution of such OCT signals. In this work, we performed
a statistical analysis of retinal OCT data. We found that the so-called stretched-exponential distribution, a two-parameter
probability density function, provides a model that describes the data in a satisfactory way. In addition, we analyzed spatial-reflectance
interdependence by studying the autocorrelation function; this analysis showed a significant correlation between contiguous
pixels about 5 μm apart. We then developed a procedure to obtain the maximum-likelihood estimate of distribution parameters
along the retinal pseudo-image. With this procedure, we analyzed their spatial dependence both along and across retinal layers.
We observed that along suitable thin layers, the two parameters were statistically constant. By exploiting this result, a
statistical procedure was developed for automatic detection of parameter variations due to retinal pathological blots. Some
first results are reported for detection of diabetic retinopathy. 相似文献

Hexanuclear thiolato‐bridged arene ruthenium metalla‐prisms of the general formula [(p‐cymene)6Ru6(SR)6(tpt)2]6+ (R=CH2Ph, CH2C6H4‐p‐tBu, CH2CH2Ph; tpt=2,4,6‐tris(4‐pyridyl)‐1,3,5‐triazine), obtained from the dinuclear precursors [(p‐cymene)2Ru2(SR)2Cl2], AgCF3SO3 and tpt, have been isolated and fully characterised as triflate salts. The metalla‐prisms are highly cytotoxic against human ovarian cancer cells, especially towards the cisplatin‐resistant cell line A2780cisR (IC50 <0.25 μM ). 相似文献
