Hazard and risk assessment of nanomaterials (NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as grouping and read-across, emphasizing the need for...
They also work with your heart to make sure your body has the oxygen-rich blood it needs to function properly. In this article, we will take a close look at how your lungs work and how they keep your body's cells supplied with oxygen and get rid of the carbon dioxide waste. We ...
Various cell lines not only differ in size and shape, but also in their growth behavior. They either grow as adherent cells (fibroblastic and epithelial cells) or in suspension (lymphoblast-like cells). Most adherent cell lines grow as a single cell layer (monolayer) attached to glass...
Sticking my head out the window like a puppy tasting the wind, I crane my neck to look at the suspension cables that effortlessly distribute thousands of tons. I want to close my eyes and imagine the barges and cranes flooding the river to construct such a masterpiece, but I can never ...
Potentially, CHO cells gained many of their advantageous characteristics, such as the ability to grow in suspension and serum-free medium or the ability to produce human-like posttranslational modifications, through their adaptability (Wurm and Wurm, 2017; Lewis et al., 2013). Cells with desirable...
A SEQUENTIAL REPAIR MODEL OF PHOTOREACTIVATION IN BACTERIA* 鈥Kinetics of photoreactivation were studied in E. coli WP2 hcr - , a strain deficient in dark repair. Cells in aqueous suspension were subjected to u.v.-irradiation, then exposed to photoreactivating light for different periods. Surviv...
Human airway epithelial (HAE) cellular models are widely used in applicative studies of the airway physiology and disease. In vitro expanded and differentiated primary HAE cells collected from patients seem to be an accurate model of human airway, offeri
b) Prepare good quality skim milk and fill the plastic bottles to 2/3 of their capacity. c) Sterilise as described in section (d) under First Passage above. d) Cool to ambient temperature. e) Inoculate with mother culture at the rate of 2 - 3%, close the bottles and immediately ...
Attention-getting lead paragraphs paint clear, simple pictures. They are easy to read. Save SAT words and flowery descriptions of the drapes in the front room for the middle of the work. Don't dilly-dally in your opening paragraph.
You scanned the original’s brain and saved the contents to a chip that could be inserted into the socket on the rear of a backup body’s neck; the flow of electric signals from the chip would pass into the artificial brain, rearranging the memory cells into the necessary configuration. ...
