Biosensors for Malaria Biomarkers
This entry discusses recent advances in the development of biosensors for the purposes of malaria diagnostics. It underscore relevant challenges that have defined the gap between biosensor development and their successful utilization in routine clinical practice within resource-limitted settings. It proposes a way to think about developing biosensors that are suitable for biomedical diagnostics applications.

Marine Microalgae for lutein
Marine microalgae are a group of microscopic photosynthetic organisms with a much faster growth rate compared to land plants. They represent a significant reservoir of bioactive compounds, nutritional ingredients, and commercial commodities for the benefit of mankind. One such bioactive compound is the carotenoid lutein, which marine microalgae biosynthesises as their accessory light-harvesting pigment. Lutein is one of the dietary requirements for humans that provides several health benefits including aiding in the prevention of macular degenerative disease, reducing the risk of stroke, heart attack, and mitigation against other metabolic syndromes. Lutein is particularly known to help to maintain the normal visual function by absorbing and attenuating the blue lights that strike the retina in our eyes. Therefore, lutein is becoming a popular bioactive compound as a dietary supplement especially nowadays due to the excessive use of electronic devices and also due to insufficient dietary lutein consumption through our normal diet. Marigold flowers are currently the predominant natural source of lutein, while marine microalgae can be a competitive sustainable alternative. Moreover, microalgae have more free lutein than marigold flowers, which is preferable since it is easily absorbed compared to the esterified forms found in marigold. Although carotenoids astaxanthin and β-carotene are currently commercially produced from specific microalgae, marine microalgae are still waiting for their commercial exploration for the production of lutein.

Chili Pepper Carotenoids: Nutraceutical Properties
Chili pepper is a prominent cultivated horticultural crop that is traditionally used for food seasoning and is applied for the treatment and prevention of multiple diseases. Its beneficial health properties are due to its abundance and variety of bioactive components, such as carotenoids, capsaicinoids, and vitamins. In particular, carotenoids have important nutraceutical properties, and several studies have focused on their potential in the prevention and treatment of human diseases.

Photoprotection of Vanilla Orchid
Vanilla orchid is a shade-loving plant that is very sensitive to high radiation. We found that blue light treatment can induce photoacclimation and enhances vanilla orchid acquired photoprotection. Blue light induces chloroplast avoidance, increases antioxidant enzyme activities, and enhances photosynthesis rate when vanilla orchid is exposed to high light stress. This study found that acclimating vanilla orchid with blue light before transplantation to the field might eliminate photoinhibition and enhance vanilla growth and production.

Biomedical Effects of Graviola
A member of the Annonaceae (Custard-apple family), Annona muricata, commonly known as soursop, graviola, paw-paw, or “guanabana”, is a tree native to Central America and West Indies that is abundant at altitudes lower than 900 m above sea level.

Chinese Hamster Ovary-K1 Cells
CHO cells are epithelial-like cells isolated from Chinese hamster ovary. The original CHO cells are cultured adherently, but they can be cultured in suspension in serum-free medium after acclimation. CHO cells are widely used for the expression of recombinant proteins.

Cloned Goats
The Cloned Goats or Transgenic Cloned Goats are generated and/or multiplied by one the most advanced and widely applied assisted reproductive technologies (ARTs) designated as somatic cell cloning or somatic cell nuclear transfer (SCNT). The SCNT-derived goats can provide a valuable tool for a variety of transgenic, biomedical, biopharmaceutical and nutri-biotechnological research.

Development of Single-cell RNA Sequencing
Single-cell RNA sequencing (scRNA-seq) technology provides a powerful tool for understanding complex biosystems at the single-cell and single-molecule level. The application of droplet- and microwell-based microfluidics in scRNA-seq has contributed greatly to improving sequencing throughput.

Working Animal
A working animal is an animal, usually domesticated, that is kept by humans and trained to perform tasks instead of being slaughtered to harvest animal products. Some are beasts of burden (draught animals) that provide transportation (e.g. riding horses and camels) and aid in physical labor (e.g. oxens and elephants), while others are service animals trained to execute certain specialized tasks (e.g. hunting and guide dogs, messenger pigeons and fishing cormorants). They may also be used for milking or herding. Some, at the end of their working lives, may also be used for meat or other products such as leather. The history of working animals may predate agriculture, with dogs used by our hunter-gatherer ancestors. Around the world, millions of animals work in relationship with their owners. Domesticated species are often bred for different uses and conditions, especially horses and working dogs. Working animals are usually raised on farms, though some are still captured from the wild, such as dolphins and some Asian elephants. People have found uses for a wide variety of abilities in animals, and even industrialised societies use many animals for work. People use the strength of horses, elephants, and oxen to pull carts and move loads. Police forces use dogs for finding illegal substances and assisting in apprehending wanted persons, others use dogs to find game or search for missing or trapped people. People use various animals — camels, donkeys, horses, dogs, etc.—for transport, either for riding or to pull wagons and sleds. Other animals, including dogs and monkeys, help disabled people. On rare occasions, wild animals are not only tamed, but trained to perform work—though often solely for novelty or entertainment, as such animals tend to lack the trustworthiness and mild temper of true domesticated working animals. Conversely, not all domesticated animals are working animals. For example, while cats may catch mice, it is an instinctive behaviour, not one that can be trained by human intervention. Other domesticated animals, such as sheep or rabbits, may have agricultural uses for meat, hides and wool, but are not suitable for work. Finally, small domestic pets, such as most small birds (other than certain types of pigeon) are generally incapable of performing work other than providing companionship.

Methyl Benzoate as Insecticide
The methyl benzoate is an effective pesticide against a range of different agricultural, stored product, and urban insect pests. Methyl benzoate has several important modes of action, including as a contact toxicant, a fumigant, an ovicidal toxin, an oviposition deterrent, a repellent, and an attractant.
