BACKGROUND Peptoclostridium (Clostridium) difficile is a spore-forming bacterium responsible for nosocomial infections in humans. It is recognized as an important agent of diarrhea and colitis in several animal species and a possible zoonotic agent. Despite the known importance of P. difficile infection in humans and animals, no vaccine or other effective measure to control the disease is comme...

PURPOSE To investigate the interaction between corneal, internal, and total wavefront aberrations (WAs) and their influential factors during orthokeratology (OK) treatment in Chinese adolescents. METHODS Thirty teenagers (n = 30 eyes) were enrolled in the study; spherical equivalent refraction (SE), corneal curvature radius (CCR), central corneal thickness (CCT), WAs, and the difference in li...

Maize Agrobacterium-mediated transformation efficiency has been greatly improved in recent years. Antioxidants, such as, cysteine, can significantly improve maize transformation frequency through improving the Agrobacterium infection efficiency. However, the mechanism underlying the transformation improvement after cysteine exposure has not been elucidated. In this study, we showed that the add...

Cultivated and wild species of wheat are valuable breeding resources used for the development new cultivars with superior root traits suited to drought non-stressed conditions. The present study aimed determine genotypes phenotypic variability among intergeneric hybrids Triticum Aegilops in early vegetative (Z11) stem elongation (Z31) growth stages. Results indicated that rooting depth was 3.2-...

Abstract Tilletia controversa Kühn is the causal agent of dwarf bunt disease in wheat. Understanding infection T. practical and scientific importance for management. Here, we used scanning electron microscopy to characterize histological changes at seedling (Z12) stem elongation stages (Z31) resistant susceptible wheat cultivars after infection. At stage (Z12), structure mesophyll cells slightl...

This work describes the characterization and genome annotation of newly isolated lytic phage vB_SsoM_Z31 (referred to as Z31), from wastewater samples collected in Dalian, China. Transmission electron microscopy revealed that Z31 belongs family Myoviridae, order Caudovirales. specifically infects Shigella sonnei, dysenteriae, Escherichia coli. The is an 89,355-bp-long dsDNA molecule with a G+C ...

The increased worldwide commercial cultivation of transgenic crops during the past 20 years is accompanied with potential effects on the soil microbial communities, because many rhizosphere and endosphere bacteria play important roles in promoting plant health and growth. Previous studies reported that transgenic plants exert differential effects on soil microbial communities, especially rhizob...

The chlorination of singly and multiply charged C60 cations has been investigated with the selected-ion flow tube technique. Observations are reported for the reactions of C60 , C60 21 and C60 z31 with Cl2, CCl4, CDCl3, CH2Cl2 and CH3Cl at room temperature (295 6 2 K) in helium at a total pressure of 0.35 6 0.02 Torr. C60 z1 and C60 21 were observed not to chlorinate, or react in any other way,...
