Total Parenteral Nutrition (TPN)
Total parenteral nutrition (TPN) was first established as a life-saving approach for nutritional support in infants in 1968. Originally, the solution contained only dextrose, amino acids, minerals, and vitamins, as there were no suitable lipid solutions. To overcome this limitation, plasma was given to provide essential fatty acids. However, high carbohydrate administration during TPN can increase hepatic de novo lipogenesis and may predispose individuals to hyperglycemia, so the initial formulations were not ideal. Lipid emulsions were created to supply the necessary essential fatty acids to prevent essential fatty acid deficiency (EFAD) and to the meet energy and growth needs. While the provision of TPN containing lipid emulsions has successfully reduced the overall mortality of premature infants and infants that are intractable to enteral feeding, there have been a number of diseases that have arisen from its use. Despite line infections and sepsis being the most common issues with TPN, more complex diseases can arise during TPN use. Cholestatic liver disease historically has been among the common TPN related morbidities in infants.

Thermosensitive Gelling Rectal Systems
Thermosensitive gelling system is drug delivery system that becomes a gel at physiological temperature.  The transition sol-gel temperature (Tsol-gel) is below body temperature (<37◦C), making it possible to prepare liquid preparations, which gel back at body temperature. Thermosensitive gelling system could be used to rectal administration. Rectal drug delivery is an effective alternative to oral and parenteral treatments. This route allows for both local and systemic drug therapy. Traditional rectal dosage formulations have historically been used for localised treatments, including laxatives, hemorrhoid therapy and antipyretics. However, this form of drug dosage often feels alien and uncomfortable to a patient, encouraging refusal. Thermosensitive liquid suppositories are easier to administer to the anus as they remain liquid at lower temperatures. In addition, this rectal gel minimize the feeling of a foreign body compared with solid suppositories, does not cause any harm on mucosal layers and act as mucoadhesive to the rectal tissues preventing leakage after administration.

Documented Skeletal Collections in the United States
In the US, documented skeletal collections are a collective of human skeletons that originated (mostly) from body donations, human taphonomy facilities (e.g., the William M. Bass Donated Skeletal Collection), and anatomical dissections (e.g., Robert J. Terry Anatomical Collection). These collections are a major asset in the testing and development of methods used to infer the biological profile of human remains.

Drug Resistance in Cancer Chemotherapy
Cancer is one of the main causes of death worldwide. Despite the significant development of methods of cancer healing during the past decades, chemotherapy still remains the main method for cancer treatment. Multidrug resistance (MDR) is responsible for over 90% of deaths in cancer patients receiving traditional chemotherapeutics or novel targeted drugs. The mechanisms of MDR include elevated metabolism of xenobiotics, enhanced efflux of drugs, growth factors, increased DNA repair capacity, and genetic factors (gene mutations, amplifications, and epigenetic alterations). Rapidly increasing numbers of biomedical studies are focused on designing chemotherapeutics that are able to evade or reverse MDR.

Chitosan Biopolymer on Plant Growth
The chitosan (CHT) biopolymer is a de-acetylated chitin derivative derived from the outer shell of shrimp, shellfish, lobster, or crabs, as well as the cell wall of fungi. Because of its biodegradability, environmental non-toxicity, and biocompatibility, it is an ideal resource for sustainable agriculture. The CHT emerged as a promising agent used as a plant growth promoter. It induces plant growth by influencing plant physiological processes like nutrient uptake, cell division, cell elongation, enzymatic activation, and synthesis of protein that can eventually lead to increased yield. It also alters plant defense responses by triggering multiple useful metabolic pathways. Depending on the structures, chitosan is useful for industrial and agricultural applications.

Design of Experiments in the Advancement of Biomaterial
Optimisation of tissue engineering (TE) processes requires models that can identify relationships between the parameters to be optimised and predict structural and performance outcomes from both physical and chemical processes. Design of Experiments (DoE) methods are commonly used for optimisation purposes in addition to playing an important role in statistical quality control and systematic randomisation for experiment planning. DoE is only used for the analysis and optimisation of quantitative data (i.e., number-based, countable or measurable), while it lacks the suitability for imaging and high dimensional data analysis.
