Aim: To study the activity of angiotensin-converting enzyme (ACE) in patients with pneumonia and chronic obstructive lung diseases (COLD).
Material And Methods: Sixty nine patients with pneumonia and 77 with COLD were examined. The activity of ACE in the serum and bronchoalveolar lavage (BAL) and the effects of leukocytic elastase and concentrations of zinc, endogenous inhibitors, and activators were studied.
Results: The patients with pneumonia in the acute phase of the disease have been found to have low ACE activity in both blood and BAL. As the inflammatory process comes to an end, ACE activity normalizes. In the patients with COLD, the activity of ACE is primarily decreased at remission. When COLD aggravates, the activity of ACE in blood and BAL increases. In pneumonia and COLD, the changes in ACE activity are more profound in BAL than in blood.
Conclusion: The only cause of the altered activity of ACE in patients with COLD and pneumonia is a change in the concentration of the enzyme.

Physical behaviours during pregnancy may alter the association of maternal insulin sensitivity with neonatal adiposity: a prospective pre-birth cohort of mother-child pairs.

Background: Lower maternal insulin sensitivity during pregnancy is associated with greater fetal adiposity. Physical activity can improve insulin sensitivity, but it is not known if physical behaviours influence the known association of maternal insulin sensitivity with offspring adiposity. This study aimed to investigate the moderating impact of physical behaviours on this association.

Background: Adverse childhood events (ACEs) have been associated with an increased risk of psychiatric disorders in young adulthood. To identify at-risk individuals and potential strategies to combat the negative impacts of ACE, this study investigated the mediating role of exercise in the relationship between psychological distress and ACEs. Further, we examined the moderating effect of the BDNF polymorphism in the mediation relationship.

Present study was conducted to evaluate the detrimental impacts of exposure of Multi-walled Carbon Nanotubes (MWCNT-NP) on enzymatic activities and tissue structures in Swiss albino mice. The experimental groups of mice received MWCNT-NP for specific time period (seven or fourteen days). Two distinct doses of the MWCNT-NP solution were given orally: 0.

The generation of radicals through photo-Fenton-like reactions demonstrates significant potential for remediating emerging organic contaminants (EOCs) in complex aqueous environments. However, the excitonic effect, induced by Coulomb interactions between photoexcited electrons and holes, reduces carrier utilization efficiency in these systems. In this study, we develop Cu single-atom-loaded covalent organic frameworks (Cu/COFs) as models to modulate excitonic effects.

Background: Systemic lupus erythematosus (SLE) is a complex and incurable autoimmune disease, so several drug remission for SLE symptoms have been developed and used at present. However, treatment varies by patient and disease activity, and existing medications for SLE were far from satisfactory. Novel drug targets to be found for SLE therapy are still needed.
