Ebook "UV-B radiation and plant life: Molecular biology to ecology" deals with large-scale impacts but also how UV-B affects plants at the molecular level is also fascinating, and the UV-B photoreceptor has only recently been characterised. While UV-B radiation can be damaging, it also has a more positive role in plant photomorphogenesis. Consequently UV-B treatments are being developed as innovative approaches to improve horticulture. This book is a timely synthesis of what we know and need to know about UV-B radiation and plants.

The aim of this study was to investigate the effects of UV- irradiation, hot water dip (HWD) and ethanol vapours on the quality and storage life of moth bean sprouts (Phaseolus aconitifolius Jacq.). Moth bean seeds were washed, soaked and allowed to sprout. The sprouts were subjected to various treatments viz., ethanol vapour (30 min), hot water dip (500C for 2 min) and UV-Irradiation (10 kJm-2 for 1 h).

Fruit juices are good sources of vitamins and minerals and are associated with many health benefits. The major component of the fruit juice is water. The other most common constituent is carbohydrates which comprise sucrose, fructose, glucose and sorbitol. Also, limited amount of protein and minerals are found in fruit juices.

The penetration depth of UV light in coconut water is more because of the UV absorption coefficient of coconut water is less, thus it facilitates UV rays to pass through it. By considering all above factors, the present study was aimed to study the effect of UV-C treatment on some physicochemical properties of tender coconut water.

Understanding the underlying molecular mechanisms involved in the formation of cutaneous malignant melanoma is critical for improved diagnosis and treatment. Keratinocytic nuclear receptor Retinoid X Receptor α (RXRα) has a protective role against melanomagenesis and is involved in the regulation of keratinocyte and melanocyte homeostasis subsequent acute ultraviolet (UV) irradiation.

Quantification of mass flows in production lines and waste treatment lines, as well as quantification of energy consumption at a factory is always challenges in cleaner production and pollution control decision making. The case study has conducted at a representative steel making complex in Vietnam, simulating the material flows of water and waste streams, and energy balance (EB) for water production and wastewater treatment processes, by using STAN (subSTance flow ANalysis) and SANKEY software, respectively.

Ultraviolet B (UV-B) irradiation can influence many cellular processes. Irradiation with high UV-B doses causes chlorophyll degradation, a decrease in the expression of genes associated with photosynthesis and its subsequent inhibition.

The reaction between natural organic matter (NOM) and chlorine during disinfection of water potentially forms trihalomethanes (THMs), which are classified as dangerous, carcinogenic disinfection by-products. Thus, this study aimed to investigate the removal of NOM by using coagulation and flocculation via jar tests of the raw water collected from the Chinaimo water treatment plant in Laos.

Bergapten has long been used in combination with ultraviolet A irradiation to treat depigmentation disorder. However, extremely low bergapten contents in plants and difficulties in synthesizing bergapten have limited its application. Here, we developed an alternative bergapten-production method. We first determined the crystal structures of bergaptol O-methyltransferase from Peucedanum praeruptorum (PpBMT) and the ternary PpBMT–S-adenosyl-L-homocysteine (SAH)–bergaptol complex to identify key residues involved in bergaptol binding.

Broad bean (Vicia faba) cotyledons that were inoculated artificially with fungal pathogens or exposed to various abiotic agents were analysed for phytoalexin production. Biotic elicitors, such as Botrytis cinerea and B. allii, and abiotic elicitors, such as ultraviolet (UV) radiation (254 nm) and freezing-thawing, were used to induce phytoalexin accumulation.

Breathing clean air is important to maintain our health. Thousands of us live in areas where the air is sometimes considered unhealthy to breathe because it is polluted. One common air pollutant is ground-level ozone. The effects of ground-level ozone pollution are different than the effects of the ozone layer high up in the atmosphere, which helps protect us from receiving too much of the sun’s ultraviolet radiation. At ground level, ozone can cause breathing difficulties, aggravate lung diseases, such as asthma, and may cause permanent lung damage.

Critical aspects for the wider application of ultraviolet (UV) light in drinking water treatment sometimes have been described, in spite of the success of the method as established in the field: • Absence of well-established and generally accepted design rules • Absence of a permanently active residual agent in the treated water • Suspicions of the possible photochemical formation of by-products • Possibility of revival–reactivation by repair mechanisms of irradiated organisms • Need for operational control of the permanent reliability of the technique...

Rare patients with localized early stage mycosis fungoides can be cured with radiotherapy, often total-skin electron beam irradiation. More advanced disease has been treated with topical glucocorticoids, topical nitrogen mustard, phototherapy, psoralen with ultraviolet A (PUVA), electron beam radiation, interferon, antibodies, fusion toxins, and systemic cytotoxic therapy. Unfortunately, these treatments are palliative. Adult T Cell Lymphoma/Leukemia Adult T cell lymphoma/leukemia is one manifestation of infection by the HTLV-I retrovirus.
