Design, synthesis, molecular docking and biological evaluation of new carbazole derivatives as anticancer, and antioxidant agents.

Background: The carbazole skeleton is an important structural motif occurring naturally or synthesized chemically and has antihistaminic, antioxidant, antitumor, antimicrobial, and anti-inflammatory activities.

Objectives: This study aimed to design and synthesize a novel series of carbazole derivatives and evaluate their antiproliferative and antioxidant activities.

Methods: The synthesized compounds were characterized utilizing HRMS, H-, and C-NMR, and assessed for their anticancer, antifibrotic, and antioxidant effects utilizing reference biomedical procedures.

Evidence of remodeling in peripheral airways of patients with mild to moderate asthma: effect of hydrofluoroalkane-flunisolide.

Background: We have shown previously that inflammation in asthma is not restricted to central airways but can also be demonstrated in peripheral airways. It is not clear whether inflammation of the peripheral airways is associated with structural changes and whether this remodeling process can be modulated by deposition of inhaled corticosteroids (ICSs).

Objectives: To compare remodeling in peripheral and central airways and to investigate the effects of hydrofluoroalkane (HFA)-ICS on remodeling at these sites.

Successful treatment of a critically ill patient with disseminated coccidioidomycosis, using adjunctive interferon-gamma.

Conventional antifungal therapy was not successful for a critically ill patient who had been hospitalized for 137 days in the intensive care unit with disseminated Coccidioides immitis infection and respiratory failure. The addition of interferon- gamma to the therapeutic regimen resulted in improvement and discharge from the hospital. Adjunctive interferon- gamma used in the successful treatment of severe coccidioidomycosis has not been reported previously.

Effect of HFA-flunisolide on peripheral lung inflammation in asthma.

Background: New hydrofluoroalkane (HFA) formulations of glucocorticoids have been shown to effectively control asthma. HFA glucocorticoids are deposited across all sizes of airways, including the small ones. However, it is not clear whether they can suppress peripheral airway inflammation.

Intrapulmonary steady-state concentrations of clarithromycin and azithromycin in healthy adult volunteers.

The steady-state concentrations of clarithromycin and azithromycin in plasma were compared with concomitant concentrations in epithelial lining fluid (ELF) and alveolar macrophages (AM) obtained in intrapulmonary samples during bronchoscopy and bronchoalveolar lavage from 40 healthy, nonsmoking adult volunteers. Mean plasma clarithromycin, 14-(R)-hydroxyclarithromycin, and azithromycin concentrations were similar to those previously reported. Clarithromycin was extensively concentrated in ELF (range of mean +/- standard deviation concentrations, 34.
