Pelletizing mixed plastic wastes (MPW) has gained interest as an upcycling technology and an alternative to conventional recycling. To investigate its potential, we conducted a cost analysis and life-cycle assessment (LCA) for a conceptual pelletization facility designed to produce 1 kg of pellets per batch of MPW (comprising polyethylene-PE and polypropylene-PP). This work has the following merits: (i) evaluating environmental impact (EI), cost analysis, and mechanical strength based on actual experimental data and its comparison with local and international manufacturers; (ii) enabling the evaluation of LCA impacts of MPW pellets; and (iii) emphasizing the significance of waste management in reducing EIs.

This research presents a versatile and advanced chiral metasurface operating at multiple bands with diverse functionalities, including asymmetric transmission. The proposed metasurface effectively transforms an incoming Linearly Polarized (LP) wave into a Circularly Polarized (CP) wave.

- Bruxism is a disorder characterized by clenching or grinding teeth, often occurring unconsciously, and can be diagnosed using both non-instrumental (self-reporting and questionnaires) and instrumental methods (like electromyography and polysomnography).
- The study aimed to assess whether non-instrumental diagnostic tools are reliable enough for confirming bruxism, specifically comparing these methods to more thorough instrumental diagnoses.
- Out of 3,687 articles reviewed, only eight were deemed suitable, leading to the conclusion that non-instrumental tools alone are insufficient for a definitive diagnosis of bruxism and should be used alongside instrumental methods for better accuracy.
Background: Chronic inflammation has been increasingly recognized as an essential pathogenic mechanism for the development and progression of diabetic kidney disease (DKD). Chemerin is an adipokine which has been suggested to be related to inflammation and has been correlated with the development of diabetic complications. We aimed to explore the potential links between chemerin, TNF - α, as a marker of systemic inflammation, and the level of albuminuria in patients with type 2 diabetes mellitus (T2DM).

- * A 64-year-old female patient exhibited weakness, fatigue, and toe/finger discoloration, which, along with lab tests, led to her diagnosis of mixed cryoglobulinemia due to cryoglobulins and rheumatoid factors.
- * The patient was treated with several therapies but suffered complications, including the need for a below-knee amputation; this case highlights the importance for doctors to recognize this condition, particularly in older patients experiencing gangrene or peripheral neuropathy.
