Cancer continues to be one of the leading causes of morbidity and mortality in the US. Although the treatment of cancer has evolved over the past decades with the use of targeted therapies and immunotherapy, many of these new treatments are expensive and are not readily available to everyone. Moreover, the recent success with treatment advances are not generalized to all cancer types, as some cancers continue to be devastating without significant progress in treatment options. Hence, early detection through population screening remains a critical armament against cancer.

Enterococcus faecium strains are commonly resistant to vancomycin and β-lactams. In addition, E. faecium often causes biofilm-associated infections and these infections are difficult to treat. In this context, we investigated the activity of dosing regimens using daptomycin (DAP) (8, 10, 12, and 14 mg/kg of body weight/day) alone and in combination with ceftaroline (CPT), ampicillin (AMP), ertapenem (ERT), and rifampin (RIF) against 2 clinical strains of biofilm-producing vancomycin-resistant Enterococcus faecium (VREfm), namely, strains S447 and HOU503, in an in vitro biofilm model. HOU503 harbors common LiaS and LiaR substitutions, whereas S447 lacks mutations associated with the LiaFSR pathway. MIC results demonstrated that both strains were susceptible to DAP and resistant to CPT, AMP, ERT, and RIF. The 168-h pharmacokinetic/pharmacodynamic (PK/PD) CDC biofilm reactor models (simulating human antibiotic exposures) were used with titanium and polyurethane coupons to evaluate the efficacy of antibiotic combinations. DAP 12 and 14 achieved bactericidal activity against S447 but lacked such effect against HOU503. Addition of ERT and RIF enhanced DAP activity, allowing DAP 8 and 10 plus ERT or RIF to produce bactericidal activity against both strains at 168 h. While DAP 8 and 10 plus CPT improved killing, they did not reach bactericidal reduction against S447. Combination of AMP, CPT, ERT, or RIF resulted in enhanced and bactericidal activity for DAP against HOU503 at 168 h. Our data provide further support for the use of combinations of DAP with AMP, ERT, CPT, and RIF in infections caused by biofilm producing VREfm. Further research involving DAP combinations against biofilm-producing enterococci is warranted.

Subtractive immunization is useful for directing the immune response away from dominant epitopes to allow antibodies against less immunogenic antigens to be developed. It is also useful when there is a need to downplay the response to carriers added to peptides and recombinant proteins, such as Gst and Ig, to aid in production and purification. Subtractive immunization protocols also can be helpful if the target protein is part of a mixture (such as a cell lysate) or present on the surface of transfected cells.

The repetitive immunization at multiple sites (RIMMS) protocol capitalizes on the animal's innate immune system, which is genetically preprogrammed to recognize many antigens. By repetitively immunizing the animal, B cells that recognize the antigen are kept continuously expanding until the lymph nodes are harvested for hybridoma generation. This is a good method for making a more diverse repertoire of antibodies or antibodies directed against conformational epitopes.

• Top 10 free things to do in Amsterdam
  
• A new Amsterdam – and a new Rijksmuseum

Amsterdam is classically romantic but is also funky, forward-thinking and citizen-friendly. In the old centre, around the southern canal belt, there are these beautiful 17th-century merchants’ houses that 21st-century Amsterdammers still live in. I’ve always thought it wears its historical cloak quite casually and doesn’t just dwell in the past.

The Rijksmuseum is stunning and I love it as a fascinating, cool, accessible museum, as well as for the part it played in inspiring The Miniaturist. I came across Petronella Oortman’s doll’s house there by chance. It’s an exact scale replica of her real home, and Oortman spent a fortune having it created. I thought at the time it was an interesting story, but I didn’t think I was going to write a novel about it. I’m in its debt, really.

NASA has awarded a $2 million grant to the Jet Propulsion Laboratory, The Aerospace Corp. — and Xplore, a Seattle-based space venture — to develop the design architecture for a far-out telescope array that would use the sun's gravitational field as a lens to focus on alien planets.
