The hypothesis that individual tumor subpopulations which differ in sensitivity to chemotherapeutic agents can influence each other's drug sensitivity was investigated using a set of mouse mammary tumor subpopulations derived from the same tumor. In one set of experiments, syngeneic mice were given injections of cyclophosphamide (CY)-sensitive line 168 cells and relatively insensitive line 410 ...

Sphaerobolus stellatus Tode is a fascinating gasteroid fungus that distinguished from other fungi by the diminutive morphology of starry basidiome when mature and its peculiar strategy spore’s dispersion. This taxon ejects gleba for considerable distance as if it was cannon, therefore popularly known artillery fungus. Although species cosmopolitan, records are seldom in regions such South Ameri...

Four transplantable mammary tumors, three (66, 410, and 168cl) isolated from a spontaneously occurring strain BALB/ cfCSH mammary tumor and one (D2) arising from a BALB/c hyperplastic alveolar nodule were found to grow better in mammary fatpads than at s.c. sites. Furthermore, tumor growth was better (p < 0.05) in intact mammary glands than in cleared mammary fatpads for the D2, 410, and 66 tum...

Acipenser stellatus (stellate sturgeon) represents a sturgeon species of great importance for the scientific community and fishermen that has been intensively captured for decades. Besides of overfishing and poaching, their reproduction sites have been destroyed and their natural habitats were affected by pollution. In consequence, wild populations of stellate sturgeon have decreased dramatical...

this study was investigated the effects of dietary estradiol-17? (e2) on growth, body composition and blood indices in acipenser stellatus. fish (40.9 ? 1.1 g average initial weight; n = 60 per group) were fed with three different diets containing 0 (control), 25 and 50 mg kg-1 dietary estradiol contents to apparent satiation for seven months. the results suggested that growth rate were decreas...

Decay properties of nuclei are calculated in the mass region 1400 ≤ A < 1500. The calculations performed using adjusted Rost interaction which suggests that a new island stability exists for Z = 410 and neighboring systems. Enhanced occurs Z=410 N=1068 system.

The effects of dietary phospholipids (PL) on the performance juvenile stellate sturgeon (Acipenser stellatus) was evaluated in terms growth and feed efficiency parameters, muscle liver fatty acid profiles, activity digestive antioxidative stress enzymes, expression lipoprotein lipase (lpl) insulin-like factor (igf1). For this purpose, seven isoproteic (44% crude protein) isolipidic (17% fat) di...
