Algae as Potential Bio-Pesticides
The term algae encompasses a wide range of photosynthetic organisms that are found primarily in freshwater and marine environments, although certain representatives can thrive in terrestrial niches, either on their own or by developing symbiotic relationships with other organisms.

Bioremediation of Heavy Metals by Microorganisms
Heavy metal pollution is a major environmental problem because metal ions persist in the environment due to their non-degradable nature. The toxicity and bioaccumulation tendency of heavy metals in the environment is a serious threat to the health of living organisms. Unlike organic contaminants, chemical or biological processes cannot break down heavy metals. Hence, they can only be transformed into less toxic species.

SARS-CoV-2
In December of 2019, the first few cases of novel coronavirus-infected pneumonia were reported in Wuhan, China. Since then, in a series of novel reports, a research group from Nankai University of China (the Nankai group) presented several important findings of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2): (1) The alternative translations of Nankai CDS (a 465- or 468-bp genomic region) could produce more than 17 putative proteins of the betacoronavirus subgroup B (BB coronavirus); (2) A furin protease cleavage site (FCS) was discovered in the Spike (S) protein of SARS-CoV-2; (3) 5' UTR barcoding can be used for the detection, identification, classification and phylogenetic analysis of, but not limited to coronavirus; (4) The FCS in the SARS-CoV-2 genome was acquired through the combination of copy number variations of short tandem repeats and single nucleotide substitutions [4]; and (5) two criteria were proposed to determine the intermediate host(s).

Enzyme-Induced Carbonate Precipitation
Enzyme-induced carbonate precipitation (EICP) is a relatively new bio-cementation technique for ground improvement. In EICP, calcium carbonate (CaCO3) precipitation occurs via urea hydrolysis catalysed by the urease enzyme sourced from plants. EICP offers significant potential for innovative and sustainable engineering applications, including strengthening of soils, remediation of contaminants, enhancement of oil recovery through bio-plugging and other in situ field applications. Given the numerous potential applications of EICP, theoretical understanding of the rate and quantity of  precipitation via the ureolytic chemical reaction is vital for optimising the process.

Aldosterone
Aldosterone is a steroid hormone that is produced in the adrenal cortex. Its major renal effect is to regulate electrolyte and water homeostasis in the distal tubule, thus maintaining blood pressure and extracellular fluid homeostasis through the activation of mineralocorticoid receptors (MR) in epithelial cells [2]. Aldosterone enters an epithelial cell and binds to the MR. The complex of aldosterone and MR translocates into the nucleus and regulates gene transcription of, among others, the epithelial sodium channel (ENaC) and the signaling proteins and kinases that impact channel and transporter activity, such as serum/glucocorticoid kinases (SGKs).

Hard and Semi-Hard Cheeses Preservation
Cheese is a dairy product with potential health benefits. Cheese consumption has increased due to the significant diversity of varieties, versatility of product presentation, and changes in consumers’ lifestyles. Spoilage of hard and semi-hard cheeses can be promoted by their maturation period and/or by their long shelf-life. Therefore, preservation studies play a fundamental role in maintaining and/or increasing their shelf-life, and are of significant importance for the dairy sector.

Rice Bran Arabinoxylan Compound
Rice bran arabinoxylan compound (RBAC) is derived from defatted rice bran hydrolyzed with Lentinus edodes mycelial enzyme. It has been marketed as a functional food and a nutraceutical with health-promoting properties. Some research has demonstrated this rice bran derivative to be a potent immunomodulator, which also possesses anti-inflammatory, antioxidant, and anti-angiogenic properties. To date, research on RBAC has predominantly focused on its immunomodulatory action and application as a complementary therapy for cancer. Nonetheless, the clinical applications of RBAC can extend beyond cancer therapy.

Vaccine Technology in Bovine Theileriosis
Theileriosis is a blood piroplasmic disease that adversely affects the livestock industry, especially in tropical and sub-tropical countries. It is caused by haemoprotozoan of the Theileria genus, transmitted by hard ticks and which possesses a complex life cycle. The infection and treatment method (ITM) is currently used in the control and prevention of T. parva infection, and recombinant vaccines are still under evaluation. The use of gene gun immunization against T. parva infection has been recently evaluated.

Bacterial Biofilm Formation and Pathogenesis
Biofilm formation is an integral part of the microbial life cycle in nature. In food processing environments, bacterial transmissions occur primarily through raw or undercooked foods and by cross-contamination during unsanitary food preparation practices. Foodborne pathogens form biofilms as a survival strategy in various unfavorable environments, which also become a frequent source of recurrent contamination and outbreaks of foodborne illness.

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.
