Cyanine Derived Dyes
Cyanine dyes are compounds that typically absorb light in the visible to near-infrared-I (NIR-I) spectrum range (750–900 nm).

RBM-007
RBM-007 is an anti-FGF2 aptamer composed of 37 nucleotides, whose ribose 2′ positions are modified to resist ribonucleases, in addition to being 5′-PEGylated and 3′-conjugated with an inverted dT to confer an advantageous pharmacokinetic profile. RBM-007 binds strongly and specifically to FGF2 and does not cross-react with other FGF family proteins or heparin-binding proteins, blocking the interaction between human FGF2 and its receptors FGFR1 through FGFR4. The dissociation constant (KD) of the non-PEGylated form of RBM-007 to human FGF2 protein is 2 pM, compared to 5, 7, and 27 pM in rat, mouse, and rabbit protein, respectively, showing the high affinity of RBM-007 for different FGF2s regardless of the species difference.

1-C Metabolism in AML
One-carbon (1-C) metabolism is essential for numerous cancer cell functions, including protein and nucleic acid synthesis and maintaining cellular redox balance, and inhibition of the 1-C pathway has yielded several highly active drugs, such as methotrexate and 5-FU.

Pharmacokinetics/Pharmacogenetics in Atypical LAI Antipsychotics
Over the last two decades, pharmacogenetics and pharmacokinetics have been increasingly used in clinical practice in Psychiatry due to the high variability regarding response and side effects of antipsychotic drugs. Specifically, long-acting injectable (LAI) antipsychotics have different pharmacokinetic profile than oral formulations due to their sustained release characteristics. In addition, most of these drugs are metabolized by CYP2D6, whose interindividual genetic variability results in different metabolizer status and, consequently, into different plasma concentrations of the drugs. In this context, there is consistent evidence which supports the use of therapeutic drug monitoring (TDM) along with pharmacogenetic tests to improve safety and efficacy of antipsychotic pharmacotherapy.

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.

Propofol Sedation
Propofol is a commonly used intravenous sedative for ventilator-dependent patients. Its advantage over other sedative agents, such as benzodiazepines, is in its rapid onset and short half-life which allows for daily awakening and spontaneous breathing trials. The use of propofol is recommended by the Brain Trauma Foundation for the treatment of elevated intracranial pressure and sometimes prolonged continuous large doses are required.

Protamine-Based Strategies for RNA Transfection
Protamine is a natural cationic peptide mixture mostly known as a drug for the neutralization of heparin and as a compound in formulations of slow-release insulin. Protamine is also used for cellular delivery of nucleic acids due to opposite charge-driven coupling. This year marks 60 years since the first use of Protamine as a transfection enhancement agent. Since then, Protamine has been broadly used as a stabilization agent for RNA delivery. It has also been involved in several compositions for RNA-based vaccinations in clinical development. Protamine stabilization of RNA shows double functionality: it not only protects RNA from degradation within biological systems, but also enhances penetration into cells. A Protamine-based RNA delivery system is a flexible and versatile platform that can be adjusted according to therapeutic goals: fused with targeting antibodies for precise delivery, digested into a cell penetrating peptide for better transfection efficiency or not-covalently mixed with functional polymers.

Dabigatran in Alzheimer’s Disease
Alzheimer’s disease (AD) is caused by neurodegenerative, but also vascular and hemostatic changes in the brain. The oral thrombin inhibitor dabigatran, which has been used for over a decade in preventing thromboembolism and has a well-known pharmacokinetic, safety and antidote profile, can be an option to treat vascular dysfunction in early AD, a condition known as cerebral amyloid angiopathy (CAA). Dabigatran blocks soluble thrombin, thrombin-mediated formation of fibrin and amyloid-ß protein (Aβ)-containing fibrin clots. These clots are deposited in brain parenchyma and blood vessels in areas of CAA, leading to vascular and blood-brain barrier dysfunction, hypoperfusion and chronically reduced oxygen (hypoxia) and nutrient supply, mainly in hippocampal and neocortical brain areas. Dabigatran has the potential to preserve perfusion and oxygen delivery to the brain, and to prevent parenchymal Aß-, thrombin- and fibrin-triggered inflammatory and neurodegenerative processes, leading to synapse and neuron death, and cognitive decline.

Hydroxycinnamic Acids and Skin Damages/Disorders
Alterations of skin homeostasis are widely diffused in our everyday life both due to accidental injuries, such as wounds and burns, and physiological conditions, such as late-stage diabetes, dermatitis, or psoriasis. These events are locally characterized by an intense inflammatory response, a high generation of harmful free radicals, or an impairment in the immune response regulation, which can profoundly change the skin tissue’ repair process, vulnerability, and functionality. Moreover, diabetes diffusion, antibiotic resistance, and abuse of aggressive soaps and disinfectants following the COVID-19 emergency could be causes for the future spreading of skin disorders. In the last years, hydroxycinnamic acids and derivatives have been investigated and applied in several research fields for their anti-oxidant, anti-inflammatory, and anti-bacterial activities.

Pharmacological Interventions in Epilepsy
Epilepsy is a non-communicable disease of the brain that affects people of all ages. It is characterized by episodes of spontaneous and abnormal electrical activity in the brain. It is often accompanied by depression, anxiety, and substantially increased morbidity and mortality. A large number of third-generation antiepileptic drugs are available, but they have multiple side effects causing a decline in the quality of life. The inheritance and etiology of epilepsy are complex with multiple underlying genetic and epigenetic mechanisms. Different neurotransmitters play intricate functions to maintain the normal physiology of various neurons.
