Phytoremediation Activities of Indoor Plants: A Review | Chapter 6 | Microbiology and Biotechnology Research: An Overview Vol. 1

Plants are commonly placed indoors to improve living and working spaces. Over the past 30 years, studies have demonstrated that indoor plants can significantly reduce most types of urban air pollution. Indoor plants purify the air from the harmful and toxic compounds present in it. Since ancient times, plants have been considered an auspicious symbol for many cultural and traditional purposes. Plants have also set their significance in human lives, not only biologically but also culturally. Plants have many beneficial activities like air purification, stress reduction, and improvement in cognitive power, and they exhibit many pharmacological activities too. Besides this, plants also add colors to the bland place, which makes the place more attractive and approachable. Plants that can thrive in partial shade/ indirect sunlight or full shade conditions can be listed under indoor plants. A sedentary lifestyle indoors has also had a great impact on human health. The closed and inadequately ventilated indoor spaces lead to Sick Building Syndrome (SBS), which is caused by particulate matter, like volatile organic compounds such as benzene, toluene, ethylbenzene, xylene, formaldehyde and polyaromatic hydrocarbons, as inorganic pollutants like O₃, NO₂, SO₂, etc. and organic pollutants like CO₂, CO, etc. that is released by the appliances and furniture present indoors. Plants absorb this particulate matter from the surroundings and convert it into energy required for their growth through photosynthesis. Plants help in mood elevation by providing fresh air and visual appeal. Phytoremediation deals with cost-effective environmental restoration by using plants to clean air, soil, and water. Various studies have proven that plants improve cognitive function by introducing them indoors. This review deals with the phytoremediating activities of various houseplants.

Role of Green Tea in Brain Aging | Chapter 7 | Current Topics on Chemistry and Biochemistry Vol. 2

 Green tea use has been shown in epidemiological research to be helpful in lowering the risk of dementia. However, it's unclear which green tea components and how they work to minimise that risk. The most significant risk factor for dementia is the ageing of the brain. As a result, we focused our research on the impact of green tea in preventing brain ageing. Green tea's most important component is epigallocatechin gallate (EGCG). Although both EGCG and epigallocatechin (EGC) have been found to cross the blood–brain barrier and reach the brain parenchyma, EGCG has been shown to promote neuronal differentiation more effectively than EGC. It's also been suggested that the gut microbiota's products of EGCG decomposition aid nerve cell growth. indicating that both EGCG and its breakdown products, although with a temporal lag, operate on nerve cells Green tea, on the other hand, contains the free amino acids theanine and arginine, which have stress-relieving properties. While long-term stress increases brain ageing, the anti-stress effects of theanine and arginine slow this down. Because EGCG and caffeine counteract this effect, the ratio of these green tea components is critical for anti-stress effects. Green tea's suppression of brain ageing through stimulation of neurons by EGCG and its breakdown products, as well as the decrease of stress by theanine and arginine, are considered to be involved in lowering the incidence of dementia, according to these studies.
