Broad-spectrum sunscreens containing the TriAsorB™ filter: In vitro photoprotection and clinical evaluation of blue light-induced skin pigmentation.

Background: Blue light (BL), particularly high-energy visible (HEV) light (400-450 nm), can cause skin damage and pigmentation. Therefore, effective sunscreens should offer photoprotection beyond ultraviolet (UV) radiation to also prevent or limit BL-induced cutaneous effects.

Objectives: To evaluate the in vitro BL photostability and photoprotection properties of nine sunscreens containing the broad-spectrum UV/BL phenylene bis-diphenyltriazine (PBDT or TriAsorB™) filter, together with three other organic UV filters, and to assess the in vivo photoprotection level provided by two of these products against BL-induced skin pigmentation.

Discontinuous epitopes on the C2 domain of coagulation Factor VIII mapped by computer-designed synthetic peptides.

The occurrence of alloantibodies against Factor VIII (FVIII) is the main iatrogenic complication in haemophilia A (HA). Anti-FVIII autoantibodies may also spontaneously appear in non-HA patients, leading to acquired haemophilia A. In both contexts, the antibody response against FVIII is complex and difficult to analyse due to the lack of suitable tools.

Characteristics, mechanisms of action, and epitope mapping of anti-factor VIII antibodies.

The development of anti-factor VIII (FVIII) antibodies (Abs), also called inhibitors, is currently one of the most serious complications arising during the treatment of hemophilia A patients. Improved prevention and eradication of these Abs remain a challenge both for clinicians and scientists. Numerous studies in the literature have reported on their epitope specificity, on their mechanism of FVIII inactivation, as well as on the methods used for their detection.

Simultaneous detection and epitope mapping of anti-factor VIII antibodies.

The development of antibodies (Abs) against infused factor VIII (FVIII) is currently one of the most serious complications in the treatment of patients suffering from haemophilia A. Improved prevention and eradication of these anti-FVIII Abs remain a challenge for both clinicians and scientists. Here we describe an immunoassay to simultaneously detect and map the epitope specificity of haemophilia A patients' inhibitors by screening plasma against both heavy and light chains (HC and LC) of human plasma-derived FVIII (pFVIII).

Production and characterization of mouse monoclonal antibodies reactive to Chikungunya envelope E2 glycoprotein.

Chikungunya fever is an arbovirosis of major impact in public health in Asia and Africa. Chikungunya (CHIK) virus is member of the genus Alphavirus and belongs to the Semliki Forest (SF) antigenic complex. We describe for the first time a panel of monoclonal antibodies (MAbs) reactive to CHIK envelope E2 glycoprotein.
