The analysis of the pulmonary domain involvement in Sjögren's disease.

Background: The EULAR Sjögren's syndrome (SS) disease activity index (ESSDAI) pulmonary domain is used to assess the activity of respiratory system involvement in Sjögren's disease (SjD). The most unfavorable form of respiratory involvement in SjD, after lymphomas, is interstitial lung disease (ILD).

Objectives: The aim of the study was to assess the involvement of the respiratory system in SjD patients and the occurrence of ILD in high-resolution computed tomography (HRCT), depending on immunological markers, the influence of cigarette smoking, and the age of the patients.

Performance of Lung Ultrasound as a Screening Tool for Subclinical Rheumatoid Arthritis-Associated Interstitial Lung Disease: a Multicenter Study.

Background: The screening strategy for interstitial lung disease (ILD) in rheumatoid arthritis patients is currently debated. While high-resolution computed tomography (HRCT) is the gold standard for diagnosing ILD, its systematic use as a screening tool is not yet recommended. The role of lung ultrasound (LUS) in assessing ILD has been previously explored.

New particle formation from isoprene under upper-tropospheric conditions.

Aircraft observations have revealed ubiquitous new particle formation in the tropical upper troposphere over the Amazon and the Atlantic and Pacific oceans. Although the vapours involved remain unknown, recent satellite observations have revealed surprisingly high night-time isoprene mixing ratios of up to 1 part per billion by volume (ppbv) in the tropical upper troposphere. Here, in experiments performed with the CERN CLOUD (Cosmics Leaving Outdoor Droplets) chamber, we report new particle formation initiated by the reaction of hydroxyl radicals with isoprene at upper-tropospheric temperatures of -30 °C and -50 °C.

Synthesis and characterization of nano iron oxide biochar composite for efficient removal of crystal violet from water.

In the present study, Coconut Husk Biochar (CHB) was synthesize from widely available, locally sourced agro waste, coconut husk and characterized using different techniques like scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) analysis, Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). CHB was tested for its ability to adsorb crystal violet (CV), a commonly used cationic dye, from water. It was capable of adsorbing more than 98 % of CV from water and follows Freundlich isotherm model with pseudo second order kinetics though the overall process was unfavourable.

Collaborative dynamics and shared motivation: exploring tobacco control policy development in Zambia.

In Zambia, efforts to produce a tobacco control policy have stalled for over a decade, and the country is not yet close to developing one. Limited studies have explored the dynamics in this policy process and how they affect the attainment of policy goals and outcomes. This study explored how collaborative dynamics within tobacco control policy development shaped shared motivation among stakeholders in Zambia.
