P. aeruginosa, P. putida and B. megaterium were identified as effective antagonistic endophytes for biological control of Phytophthora foot rot in black pepper.
This work provides the first evidence for endophytic bacterial diversity in black pepper stem and roots, with biocontrol potential against P. capsici infection.”
“We have previously found that the induction of hippocampal long-term potentiation (LTP) is modulated by neuron activities in the basolateral amygdala (BLA). However, little is known about what neurotransmitter system in the BLA contributes to modulation of hippocampal LTP. In the present study, we investigated possible involvement of BLA serotonergic system in the induction of LTP at the perforant path (PP)-dentate gyrus (DG) granule cell synapses of anesthetized rats. The induction of PP-DG LTP was significantly inhibited by intra-BLA injection of the 5-HT2 receptor antagonist cinanserin (25-50 nmol), but not by intra-BLA injection of the 5-HT1.7 receptor antagonist methiothepin (50 nmol), the 5-HT3 receptor antagonist ondansetron (50 nmol) or the 5-HT4 receptor antagonist RS23597-190 (100 nmol). In addition, intra-BLA injection of the 5-HT2C receptor agonist MK212 (50 nmol) facilitated the induction of PP-DG LTP. These results
suggest that the induction of PP-DG LTP is promoted by activation of 5-HT2C receptors in the BLA. (C) 2008 Elsevier Ireland Ltd. buy Milciclib All rights reserved.”
“To determine the antimicrobial activity of nisin F against Staphylococcus aureus FHPI in the respiratory tract.
The respiratory tract of nonimmunosuppressed and immunosuppressed Wistar rats were colonized with 4 x 10(5) viable cells of S. aureus K and then treated by administering 8192 arbitrary units (AU) nisin F intranasal. Symptoms of pneumonia were detected in the trachea and lungs of immunosuppressed rats that had not been treated with nisin F. The trachea and lungs of immunosuppressed
rats treated with nisin F were healthy. No significant differences were recorded in blood cell indices. The antimicrobial activity of low concentrations nisin F (80-320 AU ml(-1)) was slightly stimulated by lysozyme and lactoferrin.
Nisin F inhibited the growth of S. aureus K in the respiratory tract of immunocompromised rats. Treatment with nisin F at 8192 AU proofed safe, as the trachea, lungs, bronchi and haematology of the rats appeared normal.
Nisin F is nontoxic and may be used to control respiratory tract infections caused by S. aureus. This is, however, a preliminary study with an animal model and need to be confirmed with studies on humans.”
“Repeated exposure to opioid drugs can lead to the development of tolerance, which manifests as a reduction in analgesic potency, and physical dependence, a response indicated by a withdrawal syndrome.
