Physico-Chemical Properties of Sodium Alginate
The macromolecules of natural origin have attracted the attention of many researchers as essential to protect the structures of unstable drug substances. After analyzing the studies carried out by various authors, researchers found that these molecules are used for both investigational and therapeutic purposes. This requires the design of certain drug delivery formulations knowing the nature of the macromolecule, its target organ, the required dose and the route of delivery. Therefore, researchers consider it important to use sodium alginate to optimize the delivery of drug substances for maximum therapeutic performance in the body after administration.

Physicochemical Characterization of Aluminum Adjuvants
Aluminum-based adjuvants will continue to be a key component of currently approved and next generation vaccines. Their large adsorptive capacity allows the combination with other immunostimulatory molecules to create a toolbox of adjuvants for selective vaccine applications. The widespread use of aluminum adjuvants is due to their excellent safety profile, which has been established through the use of hundreds of millions of doses in humans over many years, low cost, and extensive experience with licensure through regulatory agencies.

Physiological and Pathological Ageing
Physiological and pathological ageing (as exemplified by Alzheimer’s disease, AD) are characterized by a progressive decline that also includes cognition. Therapeutic ultrasound presents as a new modality to decrease the pathological load and restore cognition in AD mouse models. Moreover, it is an excellent modality to increase uptake (and hence, efficacy) of therapeutic antibodies in AD mouse models. With clinical applications in mind, the review also discusses the challenges of AD therapies more generally and what needs to be considered when therapeutic ultrasound is employed.

Physiological Cooperation between Aquaporin 5 and TRPV4
Aquaporins—among them, AQP5—are responsible for transporting water across biological membranes, which is an important process in all living organisms. The transient receptor potential channel 4 (TRPV4) is a cation channel that is mostly calcium-permeable and can also be activated by osmotic stimuli. It plays a role in a number of different functions in the body, e.g., the development of bones and cartilage, and it is involved in the body’s osmoregulation, the generation of certain types of sensation (pain), and apoptosis. Earlier studies on the uterus and the literature data aroused the interest in the physiological role of the cooperation of AQP5 and TRPV4. Understanding the cooperation between AQP5 and TRPV4 may contribute to the development of new drug candidates and the therapy of several disorders (e.g., preterm birth, cataract, ischemia/reperfusion-induced edema, exercise- or cold-induced asthma).

Physiologically Based Pharmacokinetic Modeling of Nanoparticle Biodistribution
Cancer treatment and pharmaceutical development require targeted treatment and less toxic therapeutic intervention to achieve real progress against this disease. In this scenario, nanomedicine emerged as a reliable tool to improve drug pharmacokinetics and to translate to the clinical biologics based on large molecules. However, the ability of body to recognize foreign objects together with carrier transport heterogeneity derived from the combination of particle physical and chemical properties, payload and surface modification, make the designing of effective carriers very difficult. In this scenario, physiologically based pharmacokinetic modeling can help to design the particles and eventually predict their ability to reach the target and treat the tumor. This effort is performed by scientists with specific expertise and skills and familiarity with artificial intelligence tools such as advanced software that are not usually in the “cords” of traditional medical or material researchers.

Phytocannabinoids
Non-alcoholic fatty liver disease (NAFLD) is the most frequent chronic liver disease in adults in developed countries, with a global prevalence as high as one billion. The pathogenesis of NAFLD is a multifactorial and multi-step process. Nowadays, a growing body of research suggests the considerable role of the endocannabinoid system (ECS) as a complex cell-signaling system in NAFLD development.

Phytochemicals and Parkinson’s Disease
Complementary therapies and phytonutrients derived from plant sources have been proposed as treatments for Parkinson’s disease. Numerous natural phytochemicals have emerged as therapeutically interesting compounds, drug entities, and phytochemicals for the treatment of inflammatory disorders. Additionally, numerous pharmacological studies have shown that phytochemicals are useful in treating neurodegenerative diseases (NDDs), depression, and dementia.

Phytochemicals mitigate AD mitochondrial dysfunctions
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder characterized by a decline in cognitive function and neuronal damage. Although the precise pathobiology of AD remains elusive, accumulating evidence suggests that mitochondrial dysfunction is one of the underlying causes of AD. Mutations in mitochondrial or nuclear DNA that encode mitochondrial components may cause mitochondrial dysfunction. In particular, the dysfunction of electron transport chain complexes, along with the interactions of mitochondrial pathological proteins are associated with mitochondrial dysfunction in AD. Mitochondrial dysfunction causes an imbalance in the production of reactive oxygen species, leading to oxidative stress (OS) and vice versa. Neuroin-flammation is another potential contributory factor that induces mitochondrial dysfunction. Phy-tochemicals or other natural compounds have the potential to scavenge oxygen free radicals and enhance cellular antioxidant defense systems, thereby protecting against OS-mediated cellular damage. Phytochemicals can also modulate other cellular processes, including autophagy and mitochondrial biogenesis.

Phytochemistry, Medicinal Uses and Pharmacological Activities of Parkia
Parkia is a genus of flowering plants belonging to the family Fabaceae (subfamily, Mimosoideae) with pan-tropical distribution. The word Parkia was named after the Scottish explorer Mungo Park, who drowned in the Niger River, Nigeria in January 1805. The genus Parkia (Fabaceae, Subfamily, Mimosoideae) comprises about 34 species of mostly evergreen trees widely distributed across neotropics, Asia, and Africa.

Phytomedicines Targeting Cancer Stem Cells
Phytomedicines exist either in isolated or purified form or as a mixture of different secondary metabolites, and are used to prevent and cure different diseases. Phytomedicines may also have vitamins and minerals which are believed to synergize preventive and therapeutic effects, and additionally be useful in treatment of drug-resistant cancers.
