The inclusion of this molecule in medicines or functional food products will be ineffective unless suitable systems are developed. https://www.selleckchem.com/products/jsh-23.html Zein protein may constitute an inexpensive, safe, and effective choice to produce nanoparticles (NPs) to incorporate hydrophobic molecules and overcome the bioavailability issues of RSV. In this work, we loaded RSV into zein NPs by using a nanoprecipitation method. Unloaded and RSV-loaded NPs presented average diameter values in the range of 120-180 nm, narrow size distribution (polydispersity index less then  0.150), and zeta potential of around + 20 mV. The association efficiency of the drug was equal to or greater than 77% for different initial drug loads. Scanning electron microscopy imaging revealed that zein NPs were round-shaped and presented a smooth surface. Aqueous suspensions of zein NPs were stable for at least 1 month when stored at 4 °C. The freeze-drying of zein NPs using sucrose as cryoprotectant allowed an easy re-suspension of NPs in water without significantly changing the initial colloidal properties. RSV-loaded NPs presented low cytotoxicity to the human colorectal Caco-2 and HT29-MTX cell lines. Finally, permeability studies of RSV across Caco-2 and Caco-2/HT29-MTX evidenced some ability of zein NPs to protect RSV from metabolism events. However, further investigation is needed in order to confirm the possible role of zein NPs in the metabolic stability of RSV. Overall, zein NPs may present the potential to circumvent bioavailability issues of RSV. Graphical abstract.The involvement of recent technologies, such as nanotechnology and three-dimensional printing (3DP), in drug delivery has become the utmost importance for effective and safe delivery of potent therapeutics, and thus, recent advancement for oral drug delivery through 3DP technology has been expanded. The use of computer-aided design (CAD) in 3DP technology allows the manufacturing of drug formulation with the desired release rate and pattern. Currently, the most applicable 3DP technologies in the oral drug delivery system are inkjet printing method, fused deposition method, nozzle-based extrusion system, and stereolithographic 3DP. In 2015, the first 3D-printed tablet was approved by the US Food and Drug Administration (FDA), and since then, it has opened up more opportunities in the discovery of formulation for the development of an oral drug delivery system. 3DP allows the production of an oral drug delivery device that enables tailor-made formulation with customizable size, shape, and release rate. Despite the advantages offered by 3DP technology in the drug delivery system, there are challenges in terms of drug stability, safety as well as applicability in the clinical sector. Nonetheless, 3DP has immense potential in the development of drug delivery devices for future personalized medicine. This article will give the recent advancement along with the challenges of 3DP techniques for the development of oral drug delivery. Graphical abstract.Confronting the SARS-CoV-2 outbreak has allowed us to appreciate how efficiently highly-resourced settings can respond to crises. However even such settings are not prepared to deal with the situation, and lessons are only slowly being learnt. There is still an urgent need to accelerate protocols that lead to the implementation of rapid point-of-care diagnostic testing and effective antiviral therapies. In some high-risk populations, such as dialysis patients, where several individuals are treated at the same time in a limited space and overcrowded areas, our objective must be to ensure protection to patients, the healthcare team and the dialysis ward. The difficult Italian experience may help other countries to face the challenges. The experience of the Lombardy underlines the need for gathering and sharing our data to increase our knowledge and support common, initially experience-based, and as soon as possible evidence-based position to face this overwhelming crisis.BACKGROUND Brodalumab is a fully human anti-interleukin-17 receptor A monoclonal antibody efficacious for the treatment of adults with moderate-to-severe plaque psoriasis. OBJECTIVE This study summarizes malignancy rates in psoriasis clinical studies of brodalumab. METHODS Data were pooled from one phase II study and three large, multicenter, phase III randomized studies of brodalumab for the treatment of psoriasis, including two studies with randomization to brodalumab, ustekinumab, or placebo. Data from the 52-week (brodalumab and ustekinumab) and long-term (brodalumab) pools were summarized as exposure-adjusted or follow-up time-adjusted event rates per 100 patient-years (PY). RESULTS Exposure-adjusted event rates per 100 PY at 52 weeks were lower with brodalumab (n = 4019; 3446 total PY of exposure) than with ustekinumab (n = 613; 495 total PY of exposure), including adjudicated malignancies (0.9 vs 2.6) and Surveillance, Epidemiology, and End Results (SEER)-adjudicated malignancies (0.3 vs 0.4). The exposure-adjusted event rate of adjudicated malignancies in the brodalumab group remained stable in the long-term analysis (0.9 [82 events]). CONCLUSIONS Rates of malignancy among brodalumab-treated patients with psoriasis were generally low. TRIAL REGISTRY ClinicalTrials.gov identifier NCT00975637; NCT01101100; NCT01708590 (AMAGINE-1); NCT01708603 (AMAGINE-2); NCT01708629 (AMAGINE-3).The objective was to prepare guidelines to perform the current optimum treatment by organizing effective and efficient treatments of hemangiomas and vascular malformations, confirming the safety, and systematizing treatment, employing evidence-based medicine (EBM) techniques and aimed at improvement of the outcomes. Clinical questions (CQs) were decided based on the important clinical issues. For document retrieval, key words for literature searches were set for each CQ and literature published from 1980 to the end of September 2014 was searched in Pubmed, Cochrane Library, and Japana Centra Revuo Medicina (JCRM). The strengths of evidence and recommendations acquired by systematic reviews were determined following the Medical Information Network Distribution System (MINDS) technique. A total of 33 CQs were used to compile recommendations and the subjects included efficacy of resection, sclerotherapy/embolization, drug therapy, laser therapy, radiotherapy, and other conservative treatment, differences in appropriate treatment due to the location of lesions and among symptoms, appropriate timing of treatment and tests, and pathological diagnosis deciding the diagnosis.
