Background: Colorectal cancer is the third most common type of aggressive cancers. Chemotherapy, surgery,and radiotherapy are the common therapeutic options for treating this cancer. Due to the adverse side-eff ects of these methods, immunotherapy is considered as an appropriate alternative therapeutic option. Treatment through the application of monoclonal antibodies is considered as a n...

Ricin, a member of the A-B family of ribosome-inactivating proteins, is classified as a Select Toxin by the Centers for Disease Control and Prevention because of its potential use as a biothreat agent. In an effort to engineer therapeutics for ricin, we recently produced a collection of alpaca-derived, heavy-chain only antibody VH domains (VHH or "nanobody") specific for ricin's enzymatic (RTA)...

To complete the eradication of poliovirus and to protect unvaccinated people subsequently, the development of one or more antiviral drugs will be necessary. A set of five single-domain antibody fragments (variable parts of the heavy chain of a heavy-chain antibody [VHHs]) with an in vitro neutralizing activity against poliovirus type 1 was developed previously (B. Thys, L. Schotte, S. Muylderma...

Two ampicillin-resistant (Amp(r)) isolates of Vibrio harveyi, W3B and HB3, were obtained from the coastal waters of the Indonesian island of Java. Strain W3B was isolated from marine water near a shrimp farm in North Java while HB3 was from pristine seawater in South Java. In this study, novel beta-lactamase genes from W3B (bla(VHW-1)) and HB3 (bla(VHH-1)) were cloned and their nucleotide seque...

BACKGROUND Optical molecular imaging is an emerging novel technology with applications in the diagnosis of cancer and assistance in image-guided surgery. A high tumour-to-background (T/B) ratio is crucial for successful imaging, which strongly depends on tumour-specific probes that rapidly accumulate in the tumour, while non-bound probes are rapidly cleared. Here, using pre-invasive breast canc...
