Check if the same lab product or an alternative is used in the 5 most similar protocols
We used transwell chambers (Corning, NY, USA) with an 8 μm pore size to detect cell migration. The medium was changed to a serum-free medium 24 h before the experiment, and the cells were starved and placed in a 37°C, 5% CO2 incubator. Cells were trypsinized and centrifuged. Albuterol (Suzhou Hongsen Pharmaceutical Co., Ltd., China), budesonide (AstraZeneca Pty Ltd.), and ipratropium bromide (Boehringer Ingelheim Pharma GmbH & Co. KG) were diluted in DMEM containing 0.3% BSA. The concentration was 1.0 × 10−8 times that of the original solution, and the concentration of the cell suspension was adjusted to 8.0 × 105 cells/ml added to the upper chamber of the Transwell. The intervention group was pretreated by adding the above asthma drugs in the upper chamber for 30 min, the control group was added with a basal medium in the lower chamber, and the experimental and intervention groups were added with VEGF (40 ng·ml−1) in the lower chamber. After 24 h of incubation at 37°C, the cells that had migrated to the lower surface were fixed with 4% paraformaldehyde for 15 min and stained with 1% crystal violet for 30 min. Then, the migrating cells were photographed with an inverted microscope (×200 magnification) and counted using ImageJ software.

Check if the same lab product or an alternative is used in the 5 most similar protocols
The diagnostic criteria of ventilator associated pneumonia were new or progressive lung infiltrating shadows by lung imageological examination after no less than 48 hour of mechanical ventilation or within 48 hour after extubation and moreover at least two of the following conditions are satisfied: temperature >38°C or <36°C; count of white blood cells >10×109/L or <4×109/L; there was purulent secretion in the airway. The research protocol had been approved by the ethics committee of the hospital, and the family members of all children have signed informed consent.
Children in the two groups were assisted to breath using MAQUET Serroi which was produced by Germany and whose pointers satisfied the criteria of Practical Neonatology. Children in the observation group were given oxygen-driven budesonide (Astra Zeneca Pty Ltd., Australia, Registration No.: H 20090902) nebulization, 0.5 mg each time, twice each day; oxygen flow was 6~8 L/min, and nebulization lasted for 10 to 15 minutes each time, from the moment of the diagnosis of ventilator associated pneumonia to the 3rd day after ventilator weaning.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Heat-killed bacteria (HKB) was created from a lab strain of Pseudomonas aeruginosa (ATCC 27853), purchased from Sigma-Aldrich (Oakville, ON, Canada). Using measurements of optical density, the bacteria were diluted in saline to 3 × 107 colony-forming units (CFU) per ml, before being heated at 90 °C for 15 min. A commercially available preparation of budesonide (0.5 mg/ml), suspended in deionized water, was obtained from AstraZeneca (Södertälje, Södermanland, Sweden). Bovine lipid extract surfactant (BLES) at 27 mg/ml phospholipid concentration was obtained from BLES Biochemicals (London, ON, Canada). Using saline; these preparations were combined and diluted to 10 mg/ml and 50 µg/ml for BLES and budesonide, respectively, with drug vehiculization being verified through the wet bridge transfer system as described previously [10 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
