b) Microplastics from the same field, washed away by rain, found in nature close to a stream. Primary microplastics are small pieces of plastic that are purposefully manufactured. [5] [29] They are usually used in facial cleansers and cosmetics, or in air blasting technology. In some cases, their use in medicine as vectors for drugs was ...
Microplastics, defined as plastic fragments smaller than 5 mm, and even smaller particles such as nanoplastics (NP), particles smaller than 1000 nm in diameter (0.001 mm or 1 μm), have raised concerns impacting human health. [1][2] The pervasive presence of plastics in our environment has raised concerns about their long-term impacts on human ...
That is a key point that both Gaver and McKinney stress: recycling should not be the number-one option when it comes to attacking the problem of microplastics. “Once you get to recycling, every ...
Whether these ubiquitous pollutants can reach the human brain has been a primary concern for scientists. ... “We know there is an inflammatory reaction when cells are exposed to microplastics in ...
Microplastics have been found in the ocean and the air, in our food and water. Dr. Marya Zlatnik, a San Francisco-based obstetrician who has studied environmental toxins and pregnancy, has seen ...
Primary cell culture is the ex vivo culture of cells freshly obtained from a multicellular organism, as opposed to the culture of immortalized cell lines.In general, primary cell cultures are considered more representative of in vivo tissues than cell lines, and this is recognized legally in some countries such as the UK (Human Tissue Act 2004). [1]
A flurry of recent studies have discovered microplastics and nanoplastics in human brain tissue, the testes and the penis, human blood, lung and liver tissues, urine and feces, mother’s milk and ...
Cellular differentiation is the process in which a stem cell changes from one type to a differentiated one. [2][3] Usually, the cell changes to a more specialized type. Differentiation happens multiple times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types.
