Effective cell seeding throughout the tissue scaffold often determines the success of tissue-engineering products, although most current methods focus on determining the total number, not the distribution, of the cells associated with tissue-engineering constructs. The purpose of this investigation was to establish a quick, convenient, and efficient method to quantify cell survival, distributio...

Rice in the U.S. is frequently seeded at low rates and treated before sowing with neonicotinoid or anthranilic diamide insecticides to target the rice water weevil. A previous study of the influence of seeding rate on rice water weevil densities showed an inverse relationship between seeding rates and immature weevil densities. This study investigated interactive effects of seeding rate and see...

BACKGROUND Tissue engineering with cell seeded biodegradable material has attracted attention as a novel means of treating the severely impaired heart. Here, we consider optimal preparation of a durable biograft using dynamic and static cultures. METHODS Vascular smooth muscle cells (VSMCs) derived from the rat aorta were seeded onto biodegradable material P (LA/CL) (poly-L-lactide-ε-caprolac...

In direct seeding systems, soil strength variability and crop residues increase the difficulty of seeding operation. Especially when trying to achieve uniform seeding depth that will result in reliable seed germination and plant emergence. An advanced improvement has been accomplished using direct seeding systems. However, some problems still exist in soil-machine interaction due to various rea...

Seeding strategies have a major influence on the success of viral marketing campaigns, but previous studies using computer simulations and analytical models produced conflicting recommendations about the optimal seeding strategy. We therefore compare four different seeding strategies in two complementary small-scale field experiments as well as in one real-life viral marketing campaign that inv...

Reconstructing the evolutionary history of metastases is critical for understanding their basic biological principles and has profound clinical implications. Genome-wide sequencing data has enabled modern phylogenomic methods to accurately dissect subclones and their phylogenies from noisy and impure bulk tumour samples at unprecedented depth. However, existing methods are not designed to infer...

With the popularity of BitTorrent-like P2P applications, improving its performance has been an active research area. Super-seeding, a special upload policy for the initial seeder, improves the efficiency in producing multiple seeds and reduces the uploading bytes of content initiators, thus being highly expected as a promising solution for improving downloading performance while decreasing uplo...

results: among 11 patients who underwent surgery consisted of eight males and three females. their metastasis originated from testis tumors (n = 5), renal cell carcinoma (rcc; n = 4), bladder tumor (n = 1), and prostate cancer (n = 1). their mean age was 41.27 years (range, 21-67). the mean age of the patients with rcc and testis tumor at the time of diagnosing metastasis was 54 and 24.8 years,...
