toxic and direct teratogenic potential of two dominant iranian cultivars of carthamus tinctorius (safflower), floret extracts, il 111 and lrv 51 51, were investigated. the extracts are commonly used in foods and medicinal products. neither death nor alteration of stereotype activities was observed with il 111 and lrv 51 51 extracts up to 17 g/kg in 48 h in mice and rats. haemoglobin was decreas...

This paper first establishes the asymptotic normality of plug-in sieve M estimators of possibly irregular functionals of semi-nonparametric time series models. We show that, even when the sieve score process is not a martingale difference, the asymptotic variances of plug-in sieve M estimators of irregular (i.e., slower than root-T estimable) functionals are the same as those for independent da...

nutcracker syndrome (ncs) is a rare pathology, caused by compression of the left renal vein (lrv) between the abdominal aorta (aa) and the superior mesenteric artery (sma), due to reduction of the angle between aa and sma. this leads to lrv varices, left gonadal vein varices and therefore, the pelvic congestion syndrome. for this reason, coexistence of ncs and pelvic congestion syndrome has bee...

The study was aimed at exploring the curative effects of Rubus coreanus (RC) vinegar against postmenopausal osteoporosis by using ovariectomized rats as a model. The investigations were performed in five groups: sham, ovariectomized (OVX) rats without treatment, low-dose RC vinegar (LRV)-treated OVX rats, high-dose RC vinegar (HRV)-treated OVX rats and alendronate (ALEN)-treated OVX rats. The e...

In this paper we analyse access traces to a Web proxy, looking at statistical parameters to be used in the design of a replacement policy for documents held in the cache. In the rst part of the paper we present a number of properties of the lifetime and statistics of access to documents, derived from two large trace sets coming from very diierent proxies and spanning over time intervals of up t...

Nutcracker syndrome (NCS) is the most common term for compression of the left renal vein between the superior mesenteric artery and the abdominal aorta. The development of NCS is associated with the formation of the left renal vein (LRV) from the aortic collar during the sixth to eighth week of gestation and abnormal angulation of the superior mesenteric artery from the aorta. Collateralization...

Leishmania RNA virus (LRV) has been shown to be a symbiotic component of Leishmania parasites in South America. Nested retro-transcription polymerase chain reaction was employed to investigate LRV1 presence in leishmaniasis lesions from Brazil. In endemic areas of Rio de Janeiro (RJ), no LRV1 infection was observed even with mucosal involvement. LRV1 was only detected in Leishmania (V.) guyanen...
