Ken Jones, a leading amateur microscopist, specialises in video-filming pond-life. One of his videos captures the enigmatic and graceful movement of Volvox, and he has kindly allowed us to show some extracts from his film on this page. A single Volvox colony spins through the dark waters of a pond. Daughter cells are just visible inside. Micscape Editor's note.
Heart, liver, or kidney disease. Sometimes swelling can indicate a problem such as heart, liver, or kidney disease. Ankles that swell in the evening could be a sign of retaining salt and water because of right-sided heart failure. Kidney disease can also cause foot and ankle swelling.
Pitting. In some cases, small pits are formed on the skin surface of the ankle. This is formed if the person having inflamed ankles suffers from edema, a condition marked by fluid retention in the body tissues and cells and serous cavities. Long term fluid retention in the ankles causes formation of pits on the skin.
