Chronic Kidney Disease (CKD): Pentoxifylline has shown promise in the management of chronic kidney disease, particularly in individuals with associated proteinuria and nephropathy. Studies suggest that pentoxifylline may have anti-inflammatory and antifibrotic effects on the kidneys, leading to a reduction in proteinuria and preservation of renal function. However, further research is needed to fully elucidate the role of pentoxifylline in CKD management.

- Moreover, advancements in technology have led to the development of specialized oil seals with tailored compositions. For instance, seals with higher rubber content for increased flexibility in extreme temperatures, or those with reinforced metal components for enhanced durability in high-pressure applications.

They are generally utilised for the following purposes:
Oil seals keep contaminants separate from the lubricants that keep rotating shafts and precision bearings in good working order. Oil seals are also known as rotary shaft seals, lip seals, and shaft seals.
