Neurogliovascular Unit and Cerebral-microvascular Disease
The distinctive anatomical assemble and functionally discrete multicellular cerebrovasculature dynamics confer varying rheological and blood–brain barrier (BBB) permeabilities to preserve the integrity of cerebral white matter and its neural microenvironment. This homeostasis intricately involves the neurogliovascular unit (NGVU) and glymphatic system that manages the flow of cerebrospinal fluid (CSF), interstitial fluids (ISF), metabolic waste, and clearance through the venous circulation. NGVU refers to the integration of neuronal structures, glial cells (including the microglial), and vasculature (i.e., capillaries, arteries, and/or arterioles) governed by the astrocytes.

Applications of Antimicrobial Photodynamic Therapy
Originally discovered as a relatively new anticancer therapeutic technology, photodynamic therapy (PDT) has since evolved and is now used in many therapeutic technologies. For example, it is used against viruses, such as the recently reported antiviral activity against COVID-19, bacteria, fungi, and parasites, in treating neovascular disease, in environmental sanitation and pest control, and in many other applications.

Oral siRNA Delivery for Inflammatory Bowel Disease Treatments
RNA interference (RNAi) therapies have significant potential for the treatment of inflammatory bowel diseases (IBD). Oral nanomedicines carrying small interfering RNA (siRNA) drugs include the following two: (1) Polyplex or lipoplex. (2) Polyplex or lipoplex embedded in hydrogels or polymeric materials

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.

Antitumour Activity of Natural Products Containing Isoxazole/Isoxazoline Moiety
Isoxazoles and isoxazolines are five-membered heterocyclic molecules containing nitrogen and oxygen. Isoxazole and isoxazoline are the most popular heterocyclic compounds for developing novel drug candidates. As biosynthetic technology has advanced, A growing number of natural products are being developed for cancer therapy as clinical candidates. As a result, scientists have created several isoxazole and isoxazoline derivatives with anti-cancer properties based on natural products.

Endocytic Properties of vGPCRs
Endocytosis is a fundamental process involved in trafficking of various extracellular and transmembrane molecules from the cell surface to its interior. This enables cells to communicate and respond to external environments, maintain cellular homeostasis, and transduce signals. G protein-coupled receptors (GPCRs) constitute a family of receptors with seven transmembrane alpha-helical domains (7TM receptors) expressed at the cell surface, where they regulate physiological and pathological cellular processes. Several herpesviruses encode receptors (vGPCRs) which benefits the virus by avoiding host immune surveillance, supporting viral dissemination, and thereby establishing widespread and lifelong infection, processes where receptor signaling and/or endocytosis seem central. vGPCRs are rising as potential drug targets as exemplified by the cytomegalovirus-encoded receptor US28, where its constitutive internalization has been exploited for selective drug delivery in virus infected cells. Therefore, studying GPCR trafficking is of great importance.

Bioactivity of Steroidal Arylidene Derivatives
Steroids constitute a unique class of chemical compounds, playing an important role in physiopathological processes, and have high pharmacological interest. Due to their straightforward preparation and intrinsic chemical reactivity, steroidal arylidene derivatives are important synthetic intermediates for the preparation of other compounds, particularly bearing heterocyclic systems, in addition to their relevant bioactivity with potential pharmacological interest.

CCL-11 or Eotaxin-1
CCL-11 (eotaxin) is a chemokine with an important role in allergic conditions. Recent evidence indicates that CCL-11 plays a role in brain disorders as well. CCL-11 is rapidly transported from the blood to the brain through the blood-brain barrier. Age-related increases in CCL-11 are associated with cognitive impairments in executive functions and episodic and semantic memory, and therefore, this chemokine has been described as an “Endogenous Cognition Deteriorating Chemokine” (ECDC) or “Accelerated Brain-Aging Chemokine” (ABAC).

Exosomes in Neurodegenerative Diseases
Exosomes are small bilipid layer enclosed extracellular vesicles, which were once considered as a cellular waste and functionless. These nano-vesicles of 30–150 nm in diameter carry specific proteins, lipids, functional mRNAs, and high amounts of non-coding RNAs (miRNAs, lncRNAs, and circRNAs). As the exosomes content is known to vary as per their originating and recipient cells, these vesicles can be utilized as a diagnostic biomarker for early disease detection.
