Chronic obstructive pulmonary disease is a common chronic lung disease with an ever-increasing incidence. Despite years of drug research and approvals, we are still not able to halt progress or restore normal lung function. Our previous studies have demonstrated that liver growth factor-LGF has an effect on the repair of the affected tissue in a mouse model of cigarette smoke exposure, but by what pathways it achieves this is unknown.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection causes coronavirus disease 2019 (COVID-19) and can be associated with serious complications, including acute respiratory distress syndrome. This condition is accompanied by a massive release of cytokines, also denominated cytokine storm, development of systemic oxidative stress and a prothrombotic state. In this context, it has been proposed a role for acetylcysteine (NAC) in the management of patients with COVID-19.

is the most common cause of surgical site infections and its treatment is challenging due to the emergence of multi-drug resistant strains such as methicillin-resistant (MRSA). Natural berry-derived compounds have shown antimicrobial potential, e.g.

Article Synopsis
  • The study investigates the role of arginase, an enzyme linked to inflammation, in patients with chronic obstructive pulmonary disease (COPD) during stable periods and exacerbations.
  • Results indicate that arginase activity increases significantly during COPD exacerbations, correlating with elevated levels of the inflammatory marker IL-6.
  • Even three months post-exacerbation, IL-6 and IL-8 levels, as well as arginase activity, remain high, suggesting arginase may play a role in the progression of COPD.

Cigarette smoke is considered the chief leading cause of chronic obstructive pulmonary disease (COPD). Its impact on the progressive deterioration of airways has been extensively studied, but its direct effects on the pulmonary vasculature are less known. To prove that pulmonary arterial remodeling in patients with COPD is not just a consequence of alveolar hypoxia but also due to the direct effects of cigarette smoke on the pulmonary vascular bed.
