Antiviral Functional Foods
Functional foods optimize the immune system capacity to prevent and control pathogenic viral infections. Functional foods prevention of non-communicable disease can be translated into protecting against respiratory viral infections and COVID-19. Foods with antiviral properties include fruits, vegetables, fermented foods and probiotics, olive oil, fish, nuts and seeds, herbs, roots, fungi, amino acids, peptides, and cyclotides.

Metastasis
Metastasis is the process of dissemination of a tumor, whereby cells from the primary site dislodge and find their way to other tissues where secondary tumors establish. Metastasis is the primary cause of death related to cancer. This process warrants changes in original tumoral cells and their microenvironment to establish a metastatic niche. Traditionally, cancer therapy has focused on metastasis prevention by systematic treatments or direct surgical re-sectioning. However, metastasis can still occur. More recently, new therapies direct their attention to targeting cancer stem cells. As they propose, these cells could be the orchestrators of the metastatic niche.

Pathophysiology of Coronary Artery Disease in Diabetes Mellitus
Diabetes mellitus (DM) significantly increases the risk of cardiovascular diseases (CVD), all-cause mortality and cardiovascular mortality. According to the Framingham study, patients with DM have a two-fold to four-fold increased risk of developing coronary artery disease (CAD) and myocardial infarction (MI) and a four-fold to six-fold increased risk of developing congestive heart failure (HF). Hyperglycemia represents the main initiating factor in the pathogenesis of diabetic complications.

Antibiotic Susceptibility Testing
Antibiotic susceptibility testing (AST) specifies effective antibiotic dosage and formulates a profile of empirical therapy for the proper management of an individual patient’s health against deadly infections. Therefore, rapid diagnostic plays a pivotal role in the treatment of bacterial infection.

Pathological Lying
Pathological lying, also known as mythomania and pseudologia fantastica, is a mental disorder in which the person habitually or compulsively lies. The reason for such lies often serves no obvious purpose other than to paint oneself as a hero or victim depending on the circumstance. It was first described in the medical literature in 1895 by Anton Delbrück (de). Although it is a controversial topic, pathological lying has been defined as "falsification entirely disproportionate to any discernible end in view, may be extensive and very complicated, and may manifest over a period of years or even a lifetime". A firm concept of the behaviour does not exist, nor any diagnostic criteria that health professionals accept widely; resulting in controversy regarding what it truly means to be a pathological liar. Theories to explain the root causes include stress, an attempt to shift a locus of control to an internal one, and issues relating to low self-esteem.

Attachment Therapy
Attachment therapy (also called "the Evergreen model," "holding time," "rage-reduction," "compression therapy," "rebirthing," "corrective attachment therapy," and Coercive Restraint Therapy) is a pseudoscientific child mental health intervention intended to treat attachment disorders. It is found primarily in the United States, and much of it is centered in about a dozen clinics in Evergreen, Colorado, where Foster Cline, one of the founders, established his clinic in the 1970s. The practice has resulted in adverse outcomes for children, including at least six documented child fatalities. Since the 1990s there have been a number of prosecutions for deaths or serious maltreatment of children at the hands of "attachment therapists" or parents following their instructions. Two of the most well-known cases are those of Candace Newmaker in 2000 and the Gravelles in 2003. Following the associated publicity, some advocates of attachment therapy began to alter views and practices to be less potentially dangerous to children. This change may have been hastened by the publication of a Task Force Report on the subject in January 2006, commissioned by the American Professional Society on the Abuse of Children (APSAC) which was largely critical of attachment therapy. In April 2007, ATTACh, an organization originally set up by attachment therapists, formally adopted a White Paper stating its unequivocal opposition to the use of coercive practices in therapy and parenting, promoting instead newer techniques of attunement, sensitivity and regulation. Attachment therapy is primarily based on Robert Zaslow's rage-reduction therapy from the 1960s and '70s and on psychoanalytic theories about suppressed rage, catharsis, regression, breaking down of resistance and defence mechanisms. Zaslow, Tinbergen, Martha Welch and other early proponents used it as a treatment for autism, based on the now discredited belief that autism was the result of failures in the attachment relationship with the mother. This form of treatment differs significantly from evidence-based attachment-based therapies, talking psychotherapies such as attachment-based psychotherapy and relational psychoanalysis.

Seed Waste from Custard Apple
Annona squamosa L. (custard apple or sugar apple), belonging to the Annonaceae family, is a small tree or shrub that grows natively in subtropical and tropical regions. Seeds of the custard apple have been employed in folk medicines because of the presence of bioactive chemicals/compounds such as alkaloids, flavonoids and phenolic compounds and acetogenins and cyclopeptides that are responsible for various biological activities. The seeds also show the presence of tannins, vitamin C, vitamin E and a higher content of amino acids. From investigations, it has been shown that the seeds of A. squamosa have considerable potential to be used as an antibacterial, hepatoprotective, antioxidant and antitumor/anticancer agent. Cyclosquamosin B, extracted from the custard apple seed, possesses vasorelaxant properties. Tocopherols and fatty acids, notably oleic acid and linoleic acid, are also found in the seed oil. A. squamosa seeds contain a high amount of annonaceous acetogenins compounds, which are potent mitochondrial complex I inhibitors and have high cytotoxicity. A survey primarily based on the nutritional, phytochemical and biological properties showed that A. squamosa seeds can be used for the discovery of novel products, including pharmaceutical drugs.

Skin Substitutes
The skin plays an important role in the maintenance of the human's body physiological homeostasis. It acts as a coverage that protects against infective microorganism or biomechanical impacts. Skin is also implied in thermal regulation and fluid balance. However, skin can suffer several damages that impede normal wound-healing responses and lead to chronic wounds. Since the use of autografts, allografts, and xenografts present source limitations and intense rejection associated problems, bioengineered artificial skin substitutes (BASS) have emerged as a promising solution to address these problems. The advances that have been produced on tissue engineering techniques have enabled improving and developing new arising skin substitutes. Despite this, currently available skin substitutes have many drawbacks, and an ideal skin substitute has not been developed yet. The translation of cell‐based arising skin substitutes to clinical application represents one of the critical challenges on tissue engineering and it has to be overcome with the aim of offering each patient the more efficient therapy that fits with his clinical case and allows him having a good quality of life.

Blood-Brain Barrier
The blood-brain barrier (BBB) limits pharmacotherapy of several brain disorders. In addition to structural and metabolic characteristics of the BBB, the ATP-driven, drug efflux transporter P-glycoprotein (Pgp) is a selective gatekeeper of the BBB, and thus, a primary hindrance to drug delivery into the brain.

Itxasol© in Treatment of Urinary Tract Infections
Urinary tract infections (UTIs) represent a health problem of the first magnitude since they affect large segments of the population, cause increased mortality and comorbidity, and have a high incidence of relapse. Therefore, UTIs cause a major socioeconomic concern. Current antibiotic treatments have various limitations such as the appearance of resistance to antibiotics, nephrotoxicity, and side effects such as gastrointestinal problems including microbiota alterations that contribute to increasing antibiotic resistance. In this context, Itxasol© has emerged, approved as an adjuvant for the treatment of UTIs. Designed with biomimetic principles, it is composed of arbutin, umbelliferon, and N-acetyl cysteine.
