Ethylene production rates and tissue ethylene concentrations were determined for the single-gene, Epinastic (Epi) tomato (Lycopersicon esculentum Mill.) mutant, and its parent, cv VFN8. The Epi phenotype was characterized by severe leaf epinasty, thickened stems and petioles, and a compact growth habit. In 4-day-old seedlings, ethylene production was significantly higher in Epi than in VFN8. Et...

We have evaluated seven recently synthesized vitamin D3 analogs for their abilities to inhibit clonal growth of leukemic cells, to induce leukemic cell differentiation, to stimulate clonal growth of normal myeloid committed stem cells, and to transactivate a reporter gene having a 1,25(OH)2D3 response element (VDRE). The 1,25(OH)2-20-epi-D3 showed extraordinary activity; at 10(-11) mol/L it inh...

a module m is called epi-retractable if every submodule of m is a homomorphic image of m. dually, a module m is called co-epi-retractable if it contains a copy of each of its factor modules. in special case, a ring r is called co-pli (resp. co-pri) if rr (resp. rr) is co-epi-retractable. it is proved that if r is a left principal right duo ring, then every left ideal of r is an epi-retractable ...

Methyl jasmonate and Epi-brassinolide as plant growth regulators have significant biological effects on plant growth, including increased tolerance to salt stress in plants. In this study, the effects of salinity stress and its interaction with methyl jasmonate and Epi-brassinolide on chlorophyll concentration, rate of photosynthesis, transpiration, stomatal conductance and resistance and chlor...

A module M is called epi-retractable if every submodule of M is a homomorphic image of M. Dually, a module M is called co-epi-retractable if it contains a copy of each of its factor modules. In special case, a ring R is called co-pli (resp. co-pri) if RR (resp. RR) is co-epi-retractable. It is proved that if R is a left principal right duo ring, then every left ideal of R is an epi-retractable ...

Products designed for ear cleansing (i.e., Epi-Otic and Epi-Otic New Formula [NF]a) were evaluated in vitro for their ability to kill clinical isolates of Staphylococcus intermedius, Pseudomonas aeruginosa, and the yeast Malassezia pachydermatis. Dilutions of the products at 1/5 and 1/25 in distilled water were inoculated with suspensions of the organisms and held at room temperature. The mixtu...

To determine the extent to which the effect of a physiologic increment in epinephrine (EPI) on glucose production (GP) arises indirectly from its action on peripheral tissues (muscle and adipose tissue), epinephrine was infused intraportally (EPI po) or peripherally (EPI pe) into 18-h-fasted conscious dogs maintained on a pancreatic clamp. Arterial EPI levels in EPI po and EPI pe groups rose fr...

not beginning or completing the vaccination schedule as recommended in the expanded programme on immunization is one of the major reasons for low immunization coverage. it should be studied in detail for remedial action, if the objectives of the epi in iran are to be achieved as stated. generally, lack of knowledge, lack of motivation and obstacles ore the basic categorical reasons for low cove...

in this errata, we reconsider and modify two propositions and their corollaries which were written on epi-retractable and co-epi-retractable modules.
