Vitreous Diagnosis in Neoplastic Diseases

Vitreous Diagnosis in Neoplastic Diseases

Vitreous body is an intraocular structure, origin of diverse pathologies, but is also the place where cells and inflammatory mediators are released coming from several pathologic processes. These inflammatory reactions can happen in any other ocular location like choroid, retina, optic nerve, or ciliary body and vitreous humor constitutes a stagnant reservoir for these resulting substances and ...

Roentgenologic Diagnosis of Neoplastic Diseases of the Stomach

In 1899, only four years after Roentgen's discovery, Francis H. Williams, assisted by Walter B. Cannon, examined, by means of roentgen rays, the stomachs of two children who had been given bismuth meals. The observations, which were described in detail in Williams' book, pertained chiefly to variations in size, form, and position of the stomach during the process of digestion, but in his final ...

Vitreous Mediators in Retinal Hypoxic Diseases

The causes of retinal hypoxia are many and varied. Under hypoxic conditions, a variety of soluble factors are secreted into the vitreous cavity including growth factors, cytokines, and chemokines. Cytokines, which usually serve as signals between neighboring cells, are involved in essentially every important biological process, including cell proliferation, inflammation, immunity, migration, fi...

Diseases of the Large Intestine — Neoplastic diseases —

Neoplastic lesions of the large intestine are increasing in Japan in conjunction with the changes in the dietary life of the population. Exact diagnosis of the diseases of the large intestine are still being debated. However, recent advances in diagnostic imaging provide improved diagnosis of neoplastic lesions of the large intestine without undue stress on the patient. In this paper, recent di...
