Natural Compounds with Antioxidant in Maintaining Eye Health
An antioxidant compound can be defined as a substance that can delay or prevent oxidation. The body uses different strategies against the production and accumulation of reactive oxygen species (ROS): firstly, antioxidant enzymes are used, as already reported, such as catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-px). It is important to remember that some antioxidant enzymes need micronutrients to function properly, such as zinc, selenium, copper and manganese. Secondly, ROS can be reduced or neutralized by the intake of antioxidant nutrients, such as vitamin E (a-tocopherol), beta-carotene, and vitamin C, among others. An insufficient intake of foods with antioxidant function or an unbalanced diet can alter the body’s natural antioxidant system and facilitate the damage induced by ROS. Additional defense mechanisms include antioxidant compounds, such as metallothionein, melanin, and glutathione. Eye health is crucial, and the onset of diseases can reduce vision and affect the quality of life of patients. Evidence has accumulated that polyphenols (mostly deriving from Citrus Bergamia) represent a reliable source of antioxidants able to counteract oxidative stress accompanying early stages of eye diseases. Luteolin in particular has been found to protect photoreceptors, thereby improving vision in many disease states. Moreover, a consistent anti-inflammatory response was found to occur when curcumin is used alone or in combination with other nutraceuticals. Additionally, Coenzyme Q10 has been demonstrated to produce a consistent effect in reducing ocular pressure, thereby leading to protection in patients undergoing glaucoma. Both grape seed extract, rich in anthocyanosides, and polynsatured fatty acids seem to contribute to the prevention of retinal disorders. A combination of nutraceuticals and antioxidants may represent the right solution for a multi-action activity in eye protection.

The Antioxidant Activity of Mistletoes
In addition to the European mistletoe, Viscum album, which is the most known and utilized one, there are several species commonly known as mistletoe. They are spread in various regions of the planet and are all characterized by hemiparasitism and epiphytic behaviour. The published studies evidence other similarities, including the sharing of important biological properties, with the common presence of antioxidant effects. Mistletoe is an example of the importance of the phytochemical and pharmacological research to update knowledge and utilization of medicinal plants. There are tendencies to limit to use of products derived from natural products, based on prejudices or wrong interpretation. The correct utilization of scientific results is necessary.

Cutaneous Squamous Cell Carcinoma (CSCC)
Cutaneous squamous cell carcinoma (CSCC) is the second most frequent cancer in humans and its incidence continues to rise. Although CSCC usually display a benign clinical behavior, it can be both locally invasive and metastatic. The signaling pathways involved in CSCC development have given rise to targetable molecules in recent decades. In addition, the high mutational burden and increased risk of CSCC in patients under immunosuppression were part of the rationale for developing the immunotherapy for CSCC that has changed the therapeutic landscape. Several drugs have been developed for CSCC treatment, but the disease may actually be induced by drugs as well. Molecular mechanisms underlie pharmacologically-induced CSCC, and a sound knowledge of them could help physicians better tackle this tumor.

Bioactive Compounds in Oral Stem Cell-Meditated Regeneration
Stem cells are a well-known autologous pluripotent cell source, having excellent potential to develop into specialized cells, such as brain, skin, and bone marrow cells. The oral cavity is reported to be a rich source of multiple types of oral stem cells, including the dental pulp, mucosal soft tissues, periodontal ligament, and apical papilla. Oral stem cells were useful for both the regeneration of soft tissue components in the dental pulp and mineralized structure regeneration, such as bone or dentin, and can be a viable substitute for traditionally used bone marrow stem cells.  The role of bioactive compounds in oral stem cell-meditated regeneration is discussed.

Dihydropyrimidine Dehydrogenase (DPD) Pharmacogenetics
The dihydropyrimidine dehydrogenase (DPD), encoded by the DPYD gene, is the enzyme mainly involved in the catabolism of fluoropyrimidines (FP). DPYD polymorphisms increase the risk of severe FP-related toxicity and DPYD-pharmacogenetics (DPYD-PGx) is recommended before starting the FP-based chemotherapy. Other factors influence FP safety, therefore phenotyping methods, such as measurement of plasmatic 5-fluorouracil (5-FU) clearance and DPD activity, could complement the DPYD-PGx. Here, authors reported eleven clinical cases in whom a combined genotyping/phenotyping approach, together with careful clinical monitoring was used to optimise the FP-based treatment.  In addition, authors performed a systematic review of the literature concerning the use of DPYD-PGx, together with phenotyping methods to personalise such a chemotherapy.

Effect of Curcumin Consumption on Inflammation/Oxidative Stress
Advanced chronic kidney disease (CKD) stages lead to exacerbated inflammation and oxidative stress. Patients with CKD in stage 5 need renal hemodialysis (HD) to remove toxins and waste products. However, this renal replacement therapy (RRT) is inefficient in controlling inflammation. Regular curcumin consumption has been shown to reduce inflammation and oxidative stress in subjects with chronic pathologies, suggesting that the daily intake of curcumin may alleviate these conditions in HD patients.

Transdermal Delivery of Chemotherapeutics
Chemotherapeutic drugs are primarily administered to cancer patients via oral or parenteral routes. The use of transdermal drug delivery could potentially be a better alternative to decrease the dose frequency and severity of adverse or toxic effects associated with oral or parenteral administration of chemotherapeutic drugs. The transdermal delivery of drugs has shown to be advantageous for the treatment of highly localized tumors in certain types of breast and skin cancers. In addition, the transdermal route can be used to deliver low-dose chemotherapeutics in a sustained manner. The transdermal route can also be utilized for vaccine design in cancer management, for example, vaccines against cervical cancer. However, the design of transdermal formulations may be challenging in terms of the conjugation chemistry of the molecules and the sustained and reproducible delivery of therapeutically efficacious doses.

Glutamate and GABA Dysfunction in Depression
Treatment-resistant depression (TRD) is a term used to describe a particular type of major depressive disorder (MDD). There is no consensus about what defines TRD, with various studies describing between 1 and 4 failures of antidepressant therapies, with or without electroconvulsive therapy (ECT). That is why TRD is such a growing concern among clinicians and researchers, and it explains the necessity for investigating novel therapeutic targets beyond conventional monoamine pathways. An imbalance between two primary central nervous system (CNS) neurotransmitters, L-glutamate and γ-aminobutyric acid (GABA), has emerged as having a key role in the pathophysiology of TRD.
