Green Seaweeds and Ulvan
This entry analyzed the recent trend towards, progresses towards the preparation of chemicals of, and value-added biomaterials from marine macroalgae resources, especially green seaweeds and their derived ulvan polysaccharides for various applications. In recent years, ulvan both in pristine and modified forms has gained a large amount of attention for its effective utilization in various areas due to its unique physiochemical properties, lack of exploration, and higher green seaweed production. The pristine form of ulvan (sulfated polysaccharides) is used as a bio-component; food ingredient; or a raw material for the production of numerous chemicals such as fuels, cosmetics, and pharmaceuticals, whereas its modified form is used in the sector of composites, membranes, and scaffolds, among others, because of its physicochemical properties.

Wheat Blast and Food Security
Wheat blast is a fearsome fungal disease caused by a filamentous fungus, Magnaporthe oryzae Triticum pathotype. It was first detected in Brazil in 1985, then it spread to some neighboring South American countries such as Bolivia, Argentina and Paraguay. The outbreak of wheat blast was spotted in Bangladesh for the first time in 2016, which devastated 15,000 hectares of wheat with yield losses up to 100%. Recently, it was detected in Zambia (an African country). The disease spreads through seeds and airborne conidia. There is no resistant variety against wheat blast disease. Once the disease symptoms are expressed as the bleached or partially bleached spikes, fungicide application is ineffective to control it. A convenient and rapid molecular diagnostic tool is developed for surveillance and monitoring of the wheat blast. However, our understanding the biology of wheat blast fungus and its interactions with the host plant is limited. A globally concerted effort is needed to develop durable blast-resistant varieties to combat this killer of wheat before the spread to major wheat growing countries in the world.

Biography
Paul Winchell
Paul Winchell (né Wilchinsky; December 21, 1922 – June 24, 2005) was an American ventriloquist, comedian, actor, voice artist, humanitarian, and inventor whose career flourished in the 1950s and 1960s. From 1950 to 1954, he hosted The Paul Winchell Show, which also used two other titles during its prime time run on NBC: The Speidel Show, and What's My Name?. From 1965–1968, Winchell hosted

Urinary Biomarkers for Bladder Cancer
Blue light cystoscopy (BLC) is the most recent clinical approach in the detection and diagnosis of bladder cancer, a common type of cancer with a high rate of recurrence. Representing a significant advance over previous approaches, this photodynamic diagnostic technique uses a photosensitiser prodrug as an adjunct to white light cystoscopy to enhance the in vivo detection of malignant tissues in the bladder based on their distinctive fluorescence. Whilst it does improve detection rates, BLC remains an invasive and costly procedure. Meanwhile, a variety of noninvasive urine detection methods and related microdevices have been developed.  In the following section, we provide the current context for urinary biomarker testing, including commercially available tests and recent development involving microdevices.

Tualang Honey
Tualang honey is a wild polyfloral honey produced by Apis dorsata. This honey is named after one of the tallest tropical rainforest trees, the Koompassia excelsa tree (known locally as the Tualang tree), where bees build their hives. The bees collect nectar from plants in the tropical rain forest in the North-eastern region of Peninsular Malaysia in Kedah.

Negative-Sense Single-Stranded RNA Viral Factories
Liquid–liquid phase separation (LLPS) represents a major physiochemical principle to organize intracellular membrane-less structures. Studies with non-segmented negative-sense (NNS) RNA viruses have uncovered a key role of LLPS in the formation of viral inclusion bodies (IBs), sites of viral protein concentration in the cytoplasm of infected cells. These studies further reveal the structural and functional complexity of viral IB factories as liquid-like organelles and sites of viral replication.

Proteins/Enzymes from Animal Sources
Animal proteins are good sources of protein for human, due to the composition of necessary amino acids. The quality of food depends significantly on the properties of protein inside, especially the gelation, transportation, and antimicrobial properties. Interestingly, various kinds of molecules co-exist with proteins in foodstuff, and the interactions between these can significantly affect the food quality.

Moringa oleifera
Moringa oleifera belongs to the Moringaceae family and is the best known of the native Moringa oleifera genus. For centuries, it has been used as a system of Ayurvedic and Unani medicine and has a wide range of nutritional and bioactive compounds, including proteins, essential amino acids, carbohydrates, lipids, fibre, vitamins, minerals, phenolic compounds, phytosterols and others. These characteristics allow it to have pharmacological properties, including anti-diabetic, anti-inflammatory, anticarcinogenic, antioxidant, cardioprotective, antimicrobial and hepatoprotective properties. The entire Moringa oleifera plant is edible, including its flowers, however, it is not entirely safe, because of compounds that have been found mainly in the root and bark, so the leaf was identified as the safest. Moringa oleifera is recognised as an excellent source of phytochemicals, with potential applications in functional and medicinal food preparations due to its nutritional and medicinal properties; many authors have experimented with incorporating it mainly in biscuits, cakes, brownies, meats, juices and sandwiches. The results are fascinating, as the products increase their nutritional value; however, the concentrations cannot be high, as this affects the organoleptic characteristics of the supplemented products.

Fungi on Coffee
Coffee is grown in more than 80 countries as a cash crop and consumed worldwide as a beverage and food additive. It is susceptible to fungal infection during growth, processing and storage. Fungal infections, in particular, can seriously affect the quality of coffee and threaten human health.
