HIV, HCV and SARS-CoV-2: friends or foes? A case report

Phytoestrogens. Friends or foes?

BioInformatics Pipeline Alternative Splicing Services (BIPASS) offer support to scientists interested in gathering information related to alternative splicing (AS) events. The service BIPAS–SpliceDB provides access to AS information that has been extracted a priori from various public databases and stored in a data warehouse. In contrast, the BIPAS– Align&Splice service allows scientists to sub...

Beta-agonists--friends or foes?

Bacterial toxins: friends or foes?

Many emerging and reemerging bacterial pathogens synthesize toxins that serve as primary virulence factors. We highlight seven bacterial toxins produced by well-established or newly emergent pathogenic microbes. These toxins, which affect eukaryotic cells by a variety of means, include Staphylococcus aureus alpha-toxin, Shiga toxin, cytotoxic necrotizing factor type 1, Escherichia coli heat-sta...

Human Defensins in HIV Infection: Friends or Foes?

Defensins are antimicrobial peptides (AMPs) and play an important role in both innate and adaptive immune response (Ganz, 2002; Yang et al., 2004). Defensins display broad antimicrobial activities against bacteria, fungi and viruses (Ganz, 2003; Lehrer, 2004; Zanetti, 2004),(Yang et al., 2004). Importantly, they also play a role in inflammation, tissue repair and angiogenesis (Kruse and Kristen...

Competition and quality: friends or foes?

The extensive promotion and proliferation of articles and learned essays on Total Quality Management (TQM) have filled the pages of magazines, conference proceedings and academic journals such as this over the past few years. A limited number of commentators have stuck their necks out to question some of the supposed gains that such a managerial revolution can have in terms of the intended bene...
