چکیده
In the strict sense of chemical terminology, MDI is the acronym for the monomer methylene diphenyl diisocyanate. However, the term “MDI” is also often applied to the common commercial product, which is more properly termed polymeric MDI or PMDI. Polymeric MDI, also known as “crude MDI” is actually a mixture that contains 45 55 percent MDI (monomer), with the balance being “oligomers” (polymer intermediates, such as dimers and trimers). The CAS Number for PMDI is 9016-87-9, while that for MDI monomer is 101-68-8.

Targeting surface protein SasX by active and passive vaccination to reduce Staphylococcus aureus colonization and infection.
SasX is a recently described surface protein of Staphylococcus aureus that is linked to the epidemic success of hospital-associated methicillin-resistant clones, in particular in Asia. It enhances nasal colonization and virulence in skin and lung infection models. Here, we evaluated the potential of SasX as a vaccine component in passive and active immunization efforts using mouse infection mod...
متن کاملA suppression hierarchy among competing motor programs drives sequential grooming in Drosophila
Motor sequences are formed through the serial execution of different movements, but how nervous systems implement this process remains largely unknown. We determined the organizational principles governing how dirty fruit flies groom their bodies with sequential movements. Using genetically targeted activation of neural subsets, we drove distinct motor programs that clean individual body parts....
متن کاملTaqMan real-time PCR assays to assess arbuscular mycorrhizal responses to field manipulation of grassland biodiversity: effects of soil characteristics, plant species richness, and functional traits.
Large-scale (temporal and/or spatial) molecular investigations of the diversity and distribution of arbuscular mycorrhizal fungi (AMF) require considerable sampling efforts and high-throughput analysis. To facilitate such efforts, we have developed a TaqMan real-time PCR assay to detect and identify AMF in environmental samples. First, we screened the diversity in clone libraries, generated by ...
متن کاملComparison of commercial and noncommercial endotracheal tube-securing devices.
BACKGROUND Tracheal intubation is used to establish a secure airway in patients who require mechanical ventilation. Unexpected extubation can have serious complications, including airway trauma and death. Various methods and devices have been developed to maintain endotracheal tube (ETT) security. Associated complications include pressure ulcers due to decreased tissue perfusion. Device conside...
متن کاملA New Way in Deciding NOAEL Based on the Findings from GLP-Toxicity Test
The FDA guidance focuses on the use of the NOAEL to establish the maximum recommended starting dose. The majority of NOAEL has been described inaccurately or incompletely in final reports for 90-days repeated dose toxicity test based on GLP (good laboratory practice) regulation. This is the most serious one of reasons for why most pharmaceutical companies targeting global markets have disregard...
