Inhibition of co-colonizing cystic fibrosis-associated pathogens by Pseudomonas aeruginosa and Burkholderia multivorans.

Cystic fibrosis (CF) is a recessive genetic disease characterized by chronic respiratory infections and inflammation causing permanent lung damage. Recurrent infections are caused by Gram-negative antibiotic-resistant bacterial pathogens such as Pseudomonas aeruginosa, Burkholderia cepacia complex (Bcc) and the emerging pathogen genus Pandoraea. In this study, the interactions between co-colonizing CF pathogens were investigated.

Virulence of an emerging respiratory pathogen, genus Pandoraea, in vivo and its interactions with lung epithelial cells.

Pandoraea species have emerged as opportunistic pathogens among cystic fibrosis (CF) and non-CF patients. Pandoraea pulmonicola is the predominant Pandoraea species among Irish CF patients. The objective of this study was to investigate the pathogenicity and potential mechanisms of virulence of Irish P.

Acamprosate calcium as augmentation therapy for anxiety disorders.

Background: Glutamate is a major excitatory neurotransmitter, while γ-aminobutyric acid (GABA) is a predominant inhibitory neurotransmitter in the central nervous system. This GABA-glutamate imbalance is thought to play a role in the development of anxiety. Acamprosate calcium is thought to restore this chemical imbalance in alcohol withdrawal.

"A comparison of the effectiveness of two hypnotic agents for the treatment of insomnia".

Objective: To compare the effectiveness and tolerability of two hypnotic agents, trazadone (Desyrel) and zaleplon (Sonata) on psychiatric inpatients with insomnia.

Methods: Fifteen patients who were psychiatric inpatients were assigned openly and randomly to receive either trazodone (50-100 mg) or zaleplon (10-20 mg) doses on an "as-needed basis" and followed throughout their hospital stay. Efficacy and side effect profile were subsequently assessed.
