Pure APIs were used to prepare 6 dry mixtures. The mass ratio of TAZ:PIP ranged from 50:50 to 5:95. Using an analytical balance (Kern Inc., Grove City, OH, USA, ABJ 220-4NM) and depending on the desired ratio, an appropriate amount of each API was obtained in order for a total mass of 100 mg of the standard mixture to be prepared (e.g., for the dry mixture 25:75, 25 mg TAZ and 75 mg PIP were obtained). Each mixture was placed in a special plastic container (NALGENE®, Rochester, NY, USA) having a magnetic rod and was homogenized by placing the latter on a magnetic stirrer (HANNA instruments, HI 190M (Woonsocket, RI, USA)) for 5 min.

Pure APIs were used to prepare five dry mixtures. The mass ratio of TAZ:PIP ranged from 30:70 to 10:90. Using an analytical balance (Kern Inc., Grove City, OH, USA, ABJ 220-4NM) and depending on the desired ratio, an appropriate amount of each API was obtained in order a total mass of 100 mg of the standard mixture to be prepared (e.g., for the dry mixture 20:80, 20 mg TAZ and 80 mg PIP were obtained). Each mixture was placed in a special plastic container (NALGENE®, Rochester, NY, USA) with a magnetic rod and was homogenized by placing the latter on a magnetic stirrer (HANNA instruments, HI 190M (Woonsocket, RI, USA)) for 5 min.

All products for the treatment of DED listed in the Phar-MaAnalysis database were obtained, and the packaging, the instruction leaflet, and the container (e.g., dropper bottle, MDU, SDU) were separated. Products containing ciclosporin A (Ikervis ® ), some hyaluronic acid products (Vismed ® ), and hydrocortisone (Softacort ® ) contain an additional inner packaging. This inner packaging consists of a metal (probably aluminum)-plastic compound material, for light protection. We suppose that the CO 2 equivalent generated during the production and recycling of this compound material is likely to be at least as high, but probably even significantly higher, than for plastic consisting of one component [18] (link)[19] (link)[20] (link). Thus, we have analyzed this material together with the other plastics. Each drop container was emptied and dried with compressed air. Every component (except for the container content) was measured three times using a precision scale (KERN ABJ 220-4NM), and the average was calculated (Table 1).
With the list of prescription numbers (sorted by year, name, packaging size, prescription number, and costs), the total paper and plastic waste weight was calculated for the years 2016 to 2021.

The epicitehydro samples taken from the wounds at the end of the in vivo experiments were stored in dry ice cooling until testing of the residual water content. Wet sample weight (mw) (n = 3) was determined directly after defrosting using an analytical balance (Kern ABJ 220-4NM). Afterwards, samples were air dried at room temperature until the mass achieved constancy. Dry mass (md) (n = 3) of samples was determined by weighing (Kern PCB 1000-2). The remaining water content (WC) of epicitehydro samples was calculated using the following formula: WC = ((mw − md)/mw) * 100%. To confirm these results, primary dressing average thickness (in µm) was measured through H&E-stained slides in triplicate (each slide was measured 15 times, for a total of 45 measurements per treatment). BNC dressings were not removed before fixation and posterior staining, and manual measurements of the primary dressing thickness were obtained using the Zen 3.3 Blue Edition (Zeiss Microscopy, Jena, Germany) image processing software.

Extraction of N-nitrosamines was done using method of Özbay and Şireli (2021a) . Sausage samples were broken and homogenized with a blender (Philips, HR1316/00, Istanbul, Türkiye), after 20 g sample was weighed with a precision scale (KERN, ABJ 220-4NM, Ballingen, Germany). After 40 ml DClM (Dichloromethane) (Merck, Dichlotomethane for gas chromatography, Darmstadt, Germany) was added to it. The samples were then kept in an ultrasonic water bath
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.
