New Flavonoid & Myo-Inositol Supplement
Background and Aim. Cardiovascular risk is increased in women with menopause and metabolic syndrome. Aim of this study was to test the effect of a new supplement formula, combining cocoa polyphenols, myo-inositol, and soy isoflavones, on some biomarkers of cardiovascular risk in postmenopausal women with metabolic syndrome.Methods and Results. A total of 60 women were enrolled and randomly assigned (n=30per group) to receive the supplement (NRT: 30 mg of cocoa polyphenols, 80 mg of soy isoflavones, and 2 gr of myo-inositol), or placebo for 6 months. The study protocol included three visits (baseline, 6, and 12 months) for the evaluation of glucose, triglycerides, and HDL-cholesterol (HDL-C), adiponectin, visfatin, resistin, and bone-specific alkaline phosphatase (bone-ALP). At 6 months, a significant difference between NRT and placebo was found for glucose (96±7versus108±10 mg/dL), triglycerides (145±14versus165±18 mg/dL), visfatin (2.8±0.8versus3.7±1.1 ng/mL), resistin (27±7versus32±8 µg/L), and b-ALP (19±7versus15±5 µg/mL). No difference in HDL-C concentrations nor in adiponectin levels between groups was reported at 6 months.Conclusions.The supplement used in this study improves most of the biomarkers linked to metabolic syndrome. This Trial is registered withNCT01400724.

Combination Therapy for Glioblastoma
Aggressive glioblastoma (GBM) has no known treatment as a primary brain tumor. Since the cancer is so heterogeneous, an immunosuppressive tumor microenvironment (TME) exists, and the blood–brain barrier (BBB) prevents chemotherapeutic chemicals from reaching the central nervous system (CNS), therapeutic success for GBM has been restricted. Drug delivery based on nanocarriers and nanotechnology has the potential to be a handy tool in the continuing effort to combat the challenges of treating GBM. Combination therapies may be enhanced by using nanotechnology-based delivery techniques. Nano-chemotherapy, nano-chemotherapy–radiation, nano-chemotherapy–phototherapy, and nano-chemotherapy–immunotherapy for GBM.

NO in Viral Infections
Nitric oxide is a ubiquitous signaling radical that influences critical body functions. Its importance in the cardiovascular system and the innate immune response to bacterial and viral infections has been extensively investigated. The overproduction of NO is an early component of viral infections, including those affecting the respiratory tract. The production of high levels of NO is due to the overexpression of NO biosynthesis by inducible NO synthase (iNOS), which is involved in viral clearance. The development of NO-based antiviral therapies, particularly gaseous NO inhalation and NO-donors, has proven to be an excellent antiviral therapeutic strategy.

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.

SARS-CoV-2 spike protein
The article by Suresh & Suzuki (2021) describes the finding of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein affecting human lung vascular cells and explains how the spike protein possibly increases the incidence of pulmonary arterial hypertension (PAH). Since the SARS-CoV-2 spike protein will be administered to millions of people as vaccines, it is critical to understand the effects of this protein on human cells to ensure that it does not promote long-term adverse health consequences.

Biopolymer Based Prodrugs as Potential Antineoplastic Therapy
Cancer represents a major public health issue, a substantial economic issue, and a burden for society. Limited by numerous disadvantages, conventional chemotherapy is being replaced by new strategies targeting tumor cells. In this context, therapies based on biopolymer prodrug systems represent a promising alternative for improving the pharmacokinetic and pharmacologic properties of drugs and reducing their toxicity. The polymer-directed enzyme prodrug therapy is based on tumor cell targeting and release of the drug using polymer–drug and polymer–enzyme conjugates. In addition, current trends are oriented towards natural sources. They are biocompatible, biodegradable, and represent a valuable and renewable source. Drug–polymer conjugates based on natural polymers such as chitosan (CTS), hyaluronic acid (HA), dextran (DEX), pullulan (PL), silk fibroin (SF), centyrins (CTR), heparin (HEP), and polysaccharides from Auricularia auricula (AAP) are presented.

Nano and Microemulsions for Depression and Anxiety Treatment
Most drugs used for the treatment of depression, anxiety and related disorders have low absorption, high metabolism, low brain targeting and/or low water solubility, which can make it hard to formulate them at high strength and can also lead to decreased bioavailability. Incorporating these drugs into nanometric emulsions can solve these issues. Nanometric emulsions were able to increase drug strength up to 20,270-fold (compared to aqueous solubility). The formulations showed droplet size, polydispersity index, zeta potential, viscosity, osmolality, pH, in vitro drug release and ex vivo drug permeation as adequate for the intended effect and administration route.

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.

MRNA Therapies
Currently, mRNA appears as a very promising and innovative therapeutic approach for diseases associated with functional loss of proteins, through the administration of a synthetic mRNA, which promotes the reestablishment of protein levels and restores its function. Moreover, mRNA can create new cellular functions, for example for passive immunization, allowing to stimulate the immune system, through the translation of antigenic mRNA for specific cell recognition (e.g., cancer cells) or antibody production. The fact that a relatively small amount of encoded antigen, from a synthetic mRNA, can be sufficient to obtain robust signs of efficacy, is one of the main advantages of using this biomolecule in immunotherapy. However, the global success of such mRNA-based treatments depends on a high number of these biomolecules and an effective in vivo delivery to target cells involved in a given disease. After proving that in vivo mRNA administration is possible and viable, the concept of using mRNA as a therapeutic basis was readily accepted and used in a variety of diseases, including diabetes, HIV infection, anemia, hemophilia, myocardial infarction, cancer, asthma, metabolic disorders, fibrosis, skeletal degeneration and neurological disorders, such as Friedreich’s ataxia and Alzheimer’s disease.
