to evaluate the effect of seeding rate on important agronomic traits in three winter rapeseed (brassica napus l.) cultivars, two field experiments were carried out as split plot arrangement in a complete block design with three replications during 2006-2008 growing seasons. three rapeseed cultivars (okapi, modena and licord) and three seeding rates (6, 8 and 10 kg/ha)) were randomized in main p...

Cell adhesion in three-dimensional scaffolds plays a key role in tissue development. However, stem cell behavior in electrospun scaffolds under perfusion is not fully understood. Thus, an investigation was made on the effect of flow rate and shear stress, adhesion time, and seeding density under direct perfusion in polycaprolactone electrospun scaffolds on human dental pulp stem cell detachment...

We present a 59-year-old woman who noted an enlarging lump on her forehead 6 months after a left frontotemporal craniotomy for tumor resection and chemoradiation of her primary glioblastoma multiforme (GBM). GBM is a highly aggressive intracranial neoplasm associated with the shortest survival time of any primary central nervous system malignancy. Extracranial metastasis is rare, especially wit...

We present a study to measure the relationship between seeding resolution involved in 3D diffusion tensor magnetic resonance imaging (DTI) tractography and the streamtube visualization of human brain DTI model. We investigate five scales of seeding resolution with the same brain dataset and measure the effect of the resolution difference on user performance on a set of tasks typical of those co...

Grassland and prairie restoration projects in California often result in long-term establishment of only a few native plant species, even when they begin with a diverse seed palette. One explanation for the disappearance of certain native species over time is that they are excluded through competition. If so, management that reduces interspecific competition may favor ‘‘subordinate’’ natives an...

BACKGROUND AND STUDY AIMS There have been concerns about peritoneal seeding after endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) of mucinous pancreatic cystic lesions. The aims of this study were to determine the frequency of postoperative peritoneal seeding in patients with intraductal papillary mucinous neoplasm (IPMN) who had undergone pre-operative EUS-FNA and to compare it w...

To determine the incidence and risk factors associated with tumor seeding after radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC), 781 lesions from 352 patients who had undergone ultrasound (US)-guided RFA at our hospital between April 1999 and December 2005 were examined. Of these patients, 6 presented HCC lesions (6 lesions in total) and tumor seeding (7 seedings in total), whic...

This papcrdescribes methods of managing or seeding to restore big sagebrush communities for wildlife habitat. The focus is on three bigsagebrush subspecies, Wyomingbigsagebrush (Artemi­ sia tridentata ssp. wyomingensis), basin big sagebrush (Artemisia tridentata ssp. tridentata), and mountain big sagebrush (Artemisia tridentata ssp. vaseyana). Natural colonization of the native plant community ...

This study aimed to study the effects of initial cell density and in vitro culture method on the construction of tissue-engineered bone grafts and osteogenic activities. Human mesenchymal stem cells (hMSCs) were seeded onto cubic scaffolds prepared from demineralized bone matrix (DBM) by three methods - static, hydrodynamic, or fibrin hydrogel-assisted seeding. The resulting cell-scaffold const...

There is increasing interest among growers in novel establishment systems for cover crops that can rehabilitate and protect soil. Cropping intensification has led to yield declines, compacted and poor quality soil, and increased pest problems. Cover crops in the Brassica (mustard) family offer benefits in soil conservation, improvement in soil quality, reduction in nitrate leaching, and suppres...
