Methodologies for the physico-chemical characterization of biopharmaceuticals
Biopharmaceuticals are medicinal products obtained by biotechnological processes using molecular biology methods, which include proteins, sugars, nucleic acids, cells, tissues, used for therapeutic or diagnostic purposes in vivo. Genetically modified plants, animals, or microorganisms are also potentially used to produce biopharmaceuticals.

Nanoparticles in the Intestinal Epithelial Cell Membrane
Intestinal epithelial cells are the most abundant epithelial cells in the intestine, accounting for 90–95% of intestinal cells. They are columnar cells with hair-like projections called microvilli on the apical membrane, which greatly increase the surface area available for absorption. The transintestinal cell pathway refers to the process in which nanoparticles pass through apical and basolateral membranes via intercellular transport and then discharge from the basement membrane to the extracellular space. The entire process can be divided into three stages: the uptake of nanoparticles in the apical membrane of intestinal epithelial cells, the transport of endosomes in the cytoplasm and the exocytosis of nanoparticles in the basement membrane.

3-Iodothyronamine and 3-Iodothyroacetic Acid
3-iodothyronamine (T1AM) and 3-iodothyroacetic acid (TA1) are thyroid-hormone-related compounds endowed with pharmacological activity through mechanisms that remain elusive. Some evidence suggests that they may have redox features.

Xenobiotics Modulating Aryl Hydrocarbon Receptor in Energy Homeostasis
There are fundamental sex differences in the regulation of energy homeostasis. Better understanding of the underlying mechanisms of energy balance that account for this asymmetry will assist in developing sex-specific therapies for sexually dimorphic diseases such as obesity. Multiple organs, including the hypothalamus and adipose tissue, play vital roles in the regulation of energy homeostasis, which are regulated differently in males and females. Various neuronal populations, particularly within the hypothalamus, such as arcuate nucleus (ARC), can sense nutrient content of the body by the help of peripheral hormones such leptin, derived from adipocytes, to regulate energy homeostasis. Substances from diet and environmental contaminants can exert insidious effects on energy metabolism, acting peripherally through the aryl hydrocarbon receptor (AhR). Developmental AhR activation can impart permanent alterations of neuronal development that can manifest a number of sex-specific physiological changes, which sometimes become evident only in adulthood. AhR is being investigated as a potential target for treating obesity. The consensus is that impaired function of the receptor protects from obesity in mice. AhR also modulates sex steroid receptors.

Iron-Enriched Nutritional Supplements
Iron deficiency (ID) affects people of all ages in many countries. Due to intestinal blood loss and reduced iron absorption, ID is a threat to IBD patients, women, and children the most. Current therapies can efficiently recover normal serum transferrin saturation and hemoglobin concentration but may cause several side effects, including intestinal inflammation. ID patients may benefit from innovative nutritional supplements that may satisfy iron needs without side effects. There is a growing interest in new iron-rich superfoods, like algae and mushrooms, which combine antioxidant and anti-inflammatory properties with iron richness.

Agrimonolide from Agrimonia pilosa Ledeb.
Agrimonolide (AM), which is a derivative of isocoumarins, is found mainly in the herb Agrimonia pilosa Ledeb. This compound is highly lipophilic and readily crosses the blood–brain barrier. Interest has grown in the use of AM as a multitarget natural treatment for various diseases, such as cancer, inflammation, hepatic injury, myocardial damage, and diabetes mellitus. The potential mechanisms of these pharmacological effects have been clarified at cellular and molecular levels. AM shows no cytotoxicity over a range of concentrations in different types of cells, providing evidence for its good safety profile in vitro. These findings indicate that AM is a promising medicinal agent.

Characterization of Sodium-Alginate-Based Hydrogels
Alginates are polysaccharides that are produced naturally and can be isolated from brown sea algae and bacteria. Sodium alginate (SA) is utilized extensively in the field of biological soft tissue repair and regeneration owing to its low cost, high biological compatibility, and quick and moderate crosslinking.
