Therapeutic effect of melatonin-loaded chitosan/lecithin nanoparticles on hyperglycemia and pancreatic beta cells regeneration in streptozotocin-induced diabetic rats.

Nanotechnology is used to overcome fundamental flaws in today's marketed pharmaceuticals that obstruct therapy, like restricted solubility and quick release of drugs into the bloodstream. In both human and animal researches, melatonin was demonstrated to regulate glucose levels. Despite the fact that melatonin is quickly transported through the mucosa, its sensitivity to be oxidized creates a difficulty in achieving the required dose.

Assessing number and quality of urology open access journals: 2011 to 2018.

Background/aims: There is clear evidence that publishing research in an open access (OA) journal or as an OA model is associated with higher impact, in terms of number of reads and citation rates. The development of OA journals and their quality are poorly studied in the field of urology. In this study, we aim to assess the number of OA journals, their quality in terms of CiteScore, percent cited and quartiles, and their scholarly production during the period from 2011 to 2018.

Granulomatous Lymphangitis Masquerading as Relapsed Hodgkin Disease on FDG PET/CT.

A 38-year-old woman with Hodgkin lymphoma was referred for staging fludeoxyglucose (F) positron emission tomography/computed tomography (FDG PET/CT) that showed widespread intensely FDG-avid disease in multiple nodal stations above the diaphragm and spleen and extranodal involvement in the lungs and vertebral bodies. She underwent chemotherapy and radiotherapy. Progress FDG PET/CT 5 months later showed significant metabolic and anatomic response.
