Global concerns about pollution reduction, associated with the continuous technological development of electronic equipment raises challenge for the future regarding lithium-ion batteries exploitation, use, and recovery through recycling of critical metals. Several human and environmental issues are reported, including related diseases caused by lithium waste. Lithium in Li-ion batteries can be recovered through various methods to prevent environmental contamination, and Li can be reused as a recyclable resource.

- Osteoarthritis of the knee is a prevalent condition in older adults, prompting research into effective treatments such as home exercises and pulsed electromagnetic field (PEMF) therapy to alleviate symptoms.
- A study involving 60 patients found that those receiving both PEMF and exercise showed significant improvements in muscle strength and functional measures like gait speed and pain levels compared to those who only did home exercises.
- The combination therapy particularly benefited older patients and highlighted gender differences in outcomes, indicating a promising approach for enhancing quality of life in those with knee osteoarthritis.
Osteoarthritis (OA) knee is one of the most common chronic degenerative conditions that imposes clinical and economic burdens on individuals and societies worldwide. Previous studies showed vitamin D levels correlated positively with lean muscle mass and grip strength, implying that vitamin D supplementation may improve muscle health in knee OA subjects. This randomized controlled trial (RCT) aims to compare the effects of vitamin D supplementation on knee muscle strength, physical function, pain, and sarcopenia status in patients with end-stage knee OA.

- Vitamin D deficiency is associated with poor muscle function and knee osteoarthritis, but its effect on quadriceps strength is uncertain due to varied research designs and participant differences.
- This systematic review and meta-analysis examined studies published between 2000 and March 2024, focusing on the relationship between serum 25-hydroxyvitamin D levels and quadriceps muscle strength.
- The analysis included 28 studies with over 5,700 participants, finding a significant positive correlation between vitamin D levels and isokinetic quadriceps strength at a specific speed in elderly and athletic groups, while no correlation was observed for other strength measures.
Hydrogen sulfide is present in active or extinct volcanic areas (mofettas). The habitable premises in these areas are affected by the presence of hydrogen sulfide, which, even in low concentrations, gives off a bad to unbearable smell. If the living spaces considered are closed enclosures, then a system can be designed to reduce the concentration of hydrogen sulfide.
