The Post-Lockdown Era: What Is Next in Italy?
2020
The current outbreak of the COVID-19 infection, which started in December 2019 in Wuhan (China), was declared a pandemic by the World Health Organization (WHO) on the 11th of March, 2020.
Medicinally Used Asarum Species: High-Resolution LC-MS Analysis of Aristolochic Acid Analogs and In vitro Toxicity Screening in HK-2 Cells
2017
Species of Asarum are used in traditional Chinese medicine and, similar to members of the genus Aristolochia, they contain aristolochic acid analogs (AAAs). These compounds are known for their nephrotoxic and carcinogenic effects. So far, the phytochemistry and nephrotoxicity of species of Asarum is not well studied. A high-resolution LC-MS-based metabolomic approach was used to study the phytochemical variation in medicinally used Asarum species. The cytotoxicity of the samples was assessed using human kidney (HK-2) cells. The majority of samples contained potentially nephrotoxic AAAs, including 9-methoxy aristolactam (AL) IV, AL I, and AL IV. These compounds were present in methanol as we…
Efficacy of ruxolitinib retreatment in a patient with high-risk myelofibrosis using the international prognostic scoring system
2019
Primary myelofibrosis (PMF) is a myeloproliferative neoplasm in which clonal proliferation of hematopoietic stem cells and bone marrow fibrosis coexist.1 Patients may eventually die due to leukemic progression, which occurs in up to 20% of cases, or because of cardiovascular comorbidities or cytopenia, which causes susceptibility to infections and bleeding.2 Myelofibrosis diagnosis relies upon the evaluation of several clinical and laboratory criteria suggested by the World Health Organization (WHO) in 2016.3 The major mutations leading to myelofibrosis usually occur in the JAK2, CALR, and MPL genes. However, in almost 10% of the cases, none of the above-mentioned mutations can be detected …
Dexlansoprazole Delayed Release: Pharmacotherapy of Erosive Esophagitis and GERD
2011
Dexlansoprazole MR is a modified release formulation of the R-enantiomer of lansoprazole, which employs a novel Dual Delayed Release (DDR) technology. Pharmacokinetic studies have shown that the DDR technology provides a two peaks drug release, accuring 1–2 hours and 4–5 hours after dosing, leading to an extended duration of therapeutic plasma drug concentrations compared with conventional delayed release lansoprazole. Dexlansoprazole MR 30 and 60 mg provided superior intragastric pH control compared to that obtained with lansoprazole 15 mg and 30 mg once daily dosing. Dexlansoprazole can be taken without regard to food. The drug has been shown to be as efficacious as lansoprazole in heali…

The Crosstalk Between Signaling Pathways and Cancer Metabolism in Colorectal Cancer.
2021
Colorectal cancer (CRC) is one of the most frequently diagnosed cancers worldwide. Metabolic reprogramming represents an important cancer hallmark in CRC. Reprogramming core metabolic pathways in cancer cells, such as glycolysis, glutaminolysis, oxidative phosphorylation, and lipid metabolism, is essential to increase energy production and biosynthesis of precursors required to support tumor initiation and progression. Accumulating evidence demonstrates that activation of oncogenes and loss of tumor suppressor genes regulate metabolic reprogramming through the downstream signaling pathways. Protein kinases, such as AKT and c-MYC, are the integral components that facilitate the crosstalk bet…
Targeting Oxidative Stress as a Therapeutic Approach for Idiopathic Pulmonary Fibrosis
2022
Idiopathic pulmonary fibrosis (IPF) is a chronic interstitial lung disease characterized by an abnormal reepithelialisation, an excessive tissue remodelling and a progressive fibrosis within the alveolar wall that are not due to infection or cancer. Oxidative stress has been proposed as a key molecular process in pulmonary fibrosis development and different components of the redox system are altered in the cellular actors participating in lung fibrosis. To this respect, several activators of the antioxidant machinery and inhibitors of the oxidant species and pathways have been assayed in preclinicalin vitroandin vivomodels and in different clinical trials. This review discusses the role of …
Evaluation of the IKKβ Binding of Indicaxanthin by Induced-Fit Docking, Binding Pose Metadynamics, and Molecular Dynamics
2021
Background: Indicaxanthin, a betaxanthin belonging to the betalain class of compounds, has been recently demonstrated to exert significant antiproliferative effects inducing apoptosis of human melanoma cells through the inhibition of NF-κB as the predominant pathway. Specifically, Indicaxanthin inhibited IκBα degradation in A375 cells. In resting cells, NF-κB is arrested in the cytoplasm by binding to its inhibitor protein IκBα. Upon stimulation, IκBα is phosphorylated by the IKK complex, and degraded by the proteasome, liberating free NF-κB into the nucleus to initiate target gene transcription. Inhibition of the IKK complex leads to the arrest of the NF-κB pathway.Methods: To acquire deta…

Physicochemical stability of human insulin 1 I.U./mL infusion solution in 50 mL polypropylene syringes
2021
Abstract Objectives The objective of this study was to investigate the physicochemical stability of human insulin 1 I.U./mL injection solutions (Insuman® Rapid) diluted with 0.9% NaCl solution in 50 mL disposable three-piece polypropylene syringes and stored refrigerated or at room temperature. Methods 1 I.U./mL test solutions were prepared with Insuman® Rapid and 0.9% sodium chloride infusion solution in 50 mL Original-Perfusor® syringes and BD® Perfusion syringes. Test solutions were stored for 90 days at 2–8 °C/dark or 48 h at 20–25 °C/diffuse room light in order to determine chemical stability. Additional test solutions were stored 28 days at 2–8 °C/dark followed by 24 h at 20–25 °C/dif…
