Antiviral activity of an interferon-inducing mycoviral ds RNA against Semliki Forest virus infection was considerably enhanced by N-palmitoylmuramyl-L-alanyl-D-isoglutamine (PMDP), a new muramyl dipeptide. This enhancement in activity was not due to increased production of interferon, but resulted probably from a PMDP-induced increase in nonspecific resistance to infection. These results indica...

Erythromycin-resistant Streptococcus pneumoniae isolates from young carriers were tested for their antimicrobial susceptibility; additionally, inducibility of macrolide and clindamycin resistance was investigated in pneumococci carrying erm(A), erm(B), or mef(A). Of 125 strains tested, 101 (81%) were multidrug resistant. Different levels of induction were observed with erythromycin, miocamycin,...

Abstract Gray mold is a destructive disease caused by Botrytis cinerea , pervasive plant pathogen, which poses threat to both tomato growth and postharvest storage. The utilization of induced resistance presents potential strategy for combating pathogenic attacks. ZNC (zhinengcong), an extract derived from the endophytic fungus Paecilomyces variotii has been discovered play vital role in preven...

Inducer is often used to improve the cavitation performance of pump. In order study characteristics inducer under low flow condition high-speed pump, photography technology was employed in this paper carry out visual experiments on a centrifugal rates, Cavitation distribution and evolution among were captured. The experimental results revealed that band-shaped backflow vortex inlet pipe would o...

background: bone marrow stromal cells (bmsc) are used as a source for cell therapy in different model for neurological disorder such as stroke and spinal cord injury. however, the transdifferentiation of bmsc into cholinergic phenotype requires more investigation. methods: bmsc were isolated from adult rats, pre-induced with β-mercaptoethanol (bme) and followed by nerve growth factor (ngf) indu...

The efficacy of hexanoic acid (Hx) as an inducer of resistance in tomato plants against Pseudomonas syringae pv. tomato DC3000 was previously demonstrated, and the plant response was characterized. Because little is known about the reaction of the pathogen to this effect, the goal of the present work was to determine whether the changes in the plant defence system affect the pathogen behaviour....

PURPOSE Cancer drug resistance is a major obstacle for the success of chemotherapy. Since most clinical anticancer drugs could induce drug resistance, it is desired to develop candidate drugs that are highly efficacious but incompetent to induce drug resistance. Numerous previous studies have proven that shikonin and its analogs not only are highly tumoricidal but also can bypass drug-transport...
