setacea seeds without aril, were submitted to pre-germination treatments: T1(control); T2 (pre-soaking in Promalin® solution [gibberellin (GA4+7) + N-(phenylmethyl)-1H-purine 6-amine (6-benzyladenine) both at a concentration of 18.8 g.L-1] bainMarie, 45 °C/20 min.; T3 (osmopriming with KNO3 2.6g.L-1 H2O, 25 °C/1 day, aeration); T4 2.6g.L- 1 °C/2 days, T5 (T3 followed by T2) and T6 (T4 T2...

Brownian motion is a stochastic process (Wt, t ≥ 0) such that • W0 = 0. • (Wt2 −Wt1) and (Wt4 −Wt3) are independent, for any t1 < t2 ≤ t3 < t4. • (Wt2 −Wt1) ∼ N(0, t2 − t1). • For almost all ω, the sample function t 7→Wt(ω) is continuous. Since Wt has stationary independent increments, we already know that EWt = 0 and that the covariance function is r(t, s) = t∧ s. Thus the covariance matrix of...

Multifocal basal ganglia T2*-weighted (T2*w) hypointensities, which are believed to arise mainly from vascular mineralization, were recently proposed as a novel MRI biomarker for small vessel disease and ageing. These T2*w hypointensities are typically segmented semi-automatically, which is time consuming, associated with a high intra-rater variability and low inter-rater agreement. To address ...

BACKGROUND AND PURPOSE MR changes in denervated muscles have been reported to occur within days up to several weeks after peripheral nerve damage. The purpose of this experimental study was to investigate the longitudinal changes in denervated muscles by using MR imaging. METHODS In 12 Lewis rats, the left sciatic nerve was transected at the level of the proximal thigh. MR imaging of both leg...

Sensitive profile searches and fold recognition were used to predict the structures of two yeast RNase P/MRP proteins. Rpp1p, which is one of the subunits common to eukaryotes and archaea, is predicted to adopt the seven-stranded TIM-barrel fold found in PHP phosphoesterases. Pop3p, initially thought to be one of the RNase P/MRP subunits unique to yeast, has been assigned the L7Ae/L30e fold. Th...

Nitrogen loss after urea application and the low nitrogen utilization rate of plants are major issues in fertilizer application. We therefore adopted a combination 3,4-dimethylpyrazole phosphate (DMPP) applications order to investigate response DMPP ‘sweet sapphire’ (V. vinifera L.) grape seedlings growth. Three combinations were tested screen suitable concentrations for seedlings’ Transcriptom...

The magnetic resonance (MR) imaging features of central nervous system lymphoma in eight dogs and four cats are described. Intracranial lesions affected the rostrotentorial structures in six dogs and caudotentorial structures in two cats. Lesions affected the spinal cord in two dogs and in two cats. One dog and one cat with intracranial lymphoma had signs of local extracranial extension and lym...

To examine retrospectively the prognostic significance of TP53 immunoreactivity for both tumor response and patient survival in 83 patients with nonmetastatic muscle-invasive bladder cancer treated with a single transurethral resection (TUR) of tumor and combined cisplatin-based systemic chemotherapy followed by repeat TUR, paraffin-embedded sections of a bladder tumor obtained at TUR before ch...
