The ingress of water-soluble aggressive species is a major cause to the reduced service life concrete structures. Bulk modification by adding hydrophobic agents in cementitious materials commonly applied reduce water penetration into matrix. However, conventional modifications are associated with several unresolved drawbacks such as high cost and toxicity. Here, we investigate impact safe easy-...
Submerged Cells The formation of a liquid meniscus in submerged cell cultures is common, but its impact on vitro particle dosimetry has been overlooked. In article number 2206903, through experiments and mathematical modeling, Sandor Balog, Alke Petri-Fink, co-workers identify key factors influencing nanoparticle dose observe significant gradient between the center wall culture plates.
Using Agrobacterium rhizogenes due to create hairy roots is a useful method to product secondary metabolites in many medicinal plants. The transgenic hairy roots were induced from Peganum multisectum (Maxim) Bobrov a medicinally important species, by infecting leaf and stem explant with wild type Agrobacterium rhizogenes strain ATTCC 15834, which led to the induction of hairy roots from 19% of ...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Factors influencing basophil production from the bone marrow of ovalbumin (OA)-sensitized guinea pigs have been examined in vitro. Autologous co-cultures of marrow and spleen cells from OA-immune animals contained significantly higher numbers of basophils after 7 d of liquid culture in the presence of OA, compared with control co-cultures or with marrow cultures alone (P < 0.005). Basophils inc...
OBJECTIVES Human airway epithelial cells are the principal target of human rhinovirus (HRV), a common cold pathogen that triggers the majority of asthma exacerbations. The objectives of this study were 1) to evaluate an in vitro air liquid interface cultured human airway epithelial cell model for HRV infection, and 2) to identify gene expression patterns associated with asthma intrinsically and...
We describe a new selection method based on BODIPY (4,4-difluoro-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene) staining, fluorescence activated cell sorting (FACS) and microplate-based isolation of lipid-rich microalgae from an environmental sample. Our results show that direct sorting onto solid medium upon FACS can save about 3 weeks during the scale-up process as compared with the growt...
This chapter considers the emissions of ammonia (NH 3) and nitrous oxide (N 2 O) from the excreta of agricultural animals deposited in buildings and collected as either liquid slurry or solid manure. This includes emissions from animal excreta at all stages: animal housing, manure storage and from land spreading of manures. Excreta deposited in fields by grazing animals are dealt with under SNA...
