Cutaneous calcium deposition can occur in long-term inflammation. The deposition of calcium in long-standing acne may produce either small pigmented nodules or no visible lesions. The former type is or no visible lesions. The former type is much less common, with the nodules containing particulate spheres of mineral which probably represent true osteomas. Both types of calcification can be demo...

A BENIGN calcifying epithelioma is a subcutaneous tumour, first described by Malherbe and Chenantais (1880), who called it l'epitheliome calcifie des glandes sebacees. Malherbe (1881, 1905) added more details, but only four examples of such tumours have been reported in the ophthalmic literature (Ashton, 1951; Kornblueth and Liban, 1955). Histological examination of material from the Radcliffe ...

BACKGROUND The accelerated proliferation of vascular smooth muscle cells (VSMCs) is a contributor for atherosclerosis by thickening the vascular wall. Since zinc modulation of VSMC proliferation has not been clarified, this study investigated whether zinc affects VSMC proliferation. METHODS AND RESULTS Both a rat aorta origin vascular smooth muscle cell line (A7r5 VSMCs) and primary VSMCs whi...

A small number of prokaryotic species have a unique physiology or ecology related to their development of unusually large size. The biomass of bacteria varies over more than 10 orders of magnitude, from the 0.2 microm wide nanobacteria to the largest cells of the colorless sulfur bacteria, Thiomargarita namibiensis, with a diameter of 750 microm. All bacteria, including those that swim around i...

conclusions ct is common in middle-aged working females. it affects supraspinatus tendon. it is associated with smoking. occupational risk factors are awkward positions and lifting weights. iontophoresis with 5% acetic acid and ultrasound is a safe, simple and inexpensive technique, capable to reduce pain and calcification, with a recommended degree of scientific evidence (2b). objectives to cl...
