Chronic kidney disease (CKD) progresses through mechanisms involving inflammation, fibrosis, and oxidative stress, leading to the gradual structural and functional deterioration of the kidneys. Tormentic acid (TA), a triterpenoid compound with known anti-inflammatory and antioxidant properties, shows significant potential in counteracting these pathological processes. This study explored the protective role of TA in a unilateral ureteral obstruction (UUO)-induced CKD model.

Objectives: To assess the diagnostic accuracy, in a validation cohort, of a score based on three CT items, which has shown good performance for predicting ischaemia complicating acute adhesive small-bowel obstruction (SBO).
Methods: This retrospective single-centre study of diagnostic accuracy included consecutive patients admitted for acute adhesive SBO in 2015-2022, who were treated conservatively or underwent surgery within 24 h after CT. The gold standard for ischaemia was an intraoperative diagnosis for operated patients, while the absence of ischaemia was confirmed either by its absence during surgery or by clinical follow-up in patients who did not undergo surgery.

Pulmonary inflammation is the main cause of lung injury. Phosphodiesterase 4 (PDE4) is a promising anti-inflammatory target for the treatment of respiratory diseases. Herein, we designed and synthesized 43 compounds in two novel series of benzimidazole derivatives as PDE4 inhibitors.

Background: The factors affecting the prolonged air leak (PAL) and expansion failure in the lung in patients undergoing resection for lung malignancy were analyzed. In this context, the value of the percentage of low attenuation area (LAA%) measured on preoperative quantitative chest computed tomography (Q-: CT) in predicting the development of postoperative PAL and the expansion time of the remaining lung (ET) in patients undergoing resection for lung malignancy was investigated.
Methods: The data of 202 cases who underwent lung resection between July 2020 and December 2022 were analyzed.
Sialidase fusion protein protects against influenza infection in a cigarette smoke-induced model of COPD.

First- and secondhand smokers are at an increased risk for influenza virus (IFV)-related respiratory failure and death. Despite approved influenza antiviral treatments, there is an unmet need for treatments that can improve outcomes in populations at risk for respiratory failure, including tobacco users with Chronic Obstructive Pulmonary Disease (COPD). Here we show that the sialidase fusion protein, DAS181, reduced viral burden, mitigated inflammation, and attenuated lung function loss, consistent with broad-spectrum anti-influenza responses in a mouse model of COPD and IFV-A infection.
