The Potential Role of Toll-like Receptors in Schizophrenia
Toll-like receptors (TLRs) are a family of pattern recognition receptors (PRRs) ubiquitously expressed in the human body. They protect the brain and central nervous system from self and foreign antigens/pathogens. The immune response elicited by these receptors culminates in the release of cytokines, chemokines, and interferons causing an inflammatory response, which can be both beneficial and harmful to neurodevelopment. Such changes due to TLRs are shown to be associated with alterations in cognitive functions in various neurodegenerative and psychiatric disorders, and schizophrenia is one such disorder where multiple genetic and environmental factors contribute to alterations associated with TLRs.

The Rationale of Hyperthermic Intraperitoneal Chemotherapy Treatment
Peritoneal metastases (PM) are observed in approximately 8% of patients diagnosed with colorectal cancer, either synchronously or metachronously during follow-up. PM often manifests as the sole site of metastasis. PM is associated with a poor prognosis and typically shows resistance to systemic chemotherapy. Consequently, there has been a search for alternative treatment strategies. For intraperitoneal (IP) therapy to exhibit promise, it either needed to be combined with the removal of larger tumor nodules during cytoreductive surgery or administered as repeated intermittent treatments over an extended duration to affect macroscopic tumor nodules. Cytoreductive surgery, with hyperthermic intraperitoneal chemotherapy (HIPEC) treatment as an adjunct, emerged as a solution for the former situation.

The Renin-Angiotensin-Aldosterone System
The renin-angiotensin-aldosterone system (RAAS) is comprised of two main branches, with ACE2 representing a crucial component of the protective part of the complex. The ACE2/Ang (1-7) axis is well represented in the testis, heart, brain, kidney, and intestine. Infection with the novel SARS-CoV-2 virus determines downregulation of ACE2 and interrupts the equilibrium between ACE and ACE2 in these organs.

The Role of Endocannabinoid System
The endocannabinoid system (ECS) is one of the most relevant neurotransmitter systems in the brain and plays a pivotal role in the regulation of cognitive abilities, mood, stress, and sleep.

The Role of Saponins in the Neuropathic Pain
Neuropathic pain is a chronic pain caused by tissue injury or disease involving the somatosensory nervous system, which seriously affects the patient’s body function and quality of life. Saponins are a class of compounds with diverse structures, consisting of sapogenin and glycosyl groups. The common ones of the saccharides that make up saponins are D-glucose, D-galactose, D-xylose, L-arabinose, and L-rhamnose, etc.

The Structure and Function of Integrins
Integrins are heterodimeric transmembrane proteins that mediate adhesive connections between cells and their surroundings, including surrounding cells and the extracellular matrix (ECM). They modulate tissue mechanics and regulate intracellular signaling, including cell generation, survival, proliferation, and differentiation, and the up-regulation of integrins in tumor cells has been confirmed to be associated with tumor development, invasion, angiogenesis, metastasis, and therapeutic resistance. Thus, integrins are expected to be an effective target to improve the efficacy of tumor therapy. A variety of integrin-targeting nanodrugs have been developed to improve the distribution and penetration of drugs in tumors, thereby, improving the efficiency of clinical tumor diagnosis and treatment.

The Subcutaneous Route of Administration for Therapeutic Antibodies
Therapeutic antibodies (Abs) are used in the treatment of numerous diseases, including infection, cancer, and autoimmune disorders, in which they have already demonstrated their efficacy. The success of Abs is due to (I) a high level of specificity and affinity to their target antigen, (II) a favorable safety profile, and (III) a unique pharmacokinetic profile, supporting a longer half-life as compared to other drugs. While the majority of Abs are delivered through IV injection, evidence in the literature showed that beyond the reduction of invasiveness, a better efficacy could be achieved with a local delivery of Abs. Among those routes, one has been in full development these last few years, with already good clinical results and still promising developments: The Subcutaneous route.

The Use of Deferiprone against COVID-19
Deferiprone (L1) is an EMA- and FDA-approved drug used worldwide for the treatment of iron overload and also other conditions where there are no effective treatments. The multi-potent effects and high safety record of L1 in iron loaded and non-iron loaded categories of patients suggests that L1 could be developed as a “magic bullet” drug against COVID-19 and diseases of similar symptomatology.

The Use of Dendrimers for Biomedical Applications
Dendrimers are three-dimensional nanostructures with a high degree of molecular homogeneity, adjustable size, multivalence, high surface functionality, and high aqueous solubility. Due to these important and attractive properties, dendrimers are already being used to deliver a number of drugs and are being explored as promising carriers for nucleic acid-based vaccines. Here summarizes the literature data on the biosafety of some dendrimers has been evaluated in several clinical trials.
