Restricted water diffusion has been used to distinguish pyogenic abscess from other rim-enhancing brain masses; however diffusion-weighted imaging of cerebral infection before capsule formation has rarely been described. We report a case of fungal cerebritis in which water diffusion was more restricted than that of normal contralateral brain and the measured diffusion coefficient was in the ran...

When the juvenile worms of the genus Paragonimus migrate and cause defects on the surface of the visceral pleura, pneumothorax can develop. A 34-year-old woman was admitted for pneumothorax with which was developed after she ate raw fish and crab. A 21-year-old male soldier presented with recurrent bilateral pneumothorax without eosinophilia, caused after drinking stream water frequently. In bo...

Gastric antral vascular ectasia ('water melon stomach') is a poorly documented cause of occult upper gastrointestinal blood loss. We describe a case which emphasises the clinical and pathological difficulties that can be encountered in making this elusive diagnosis.

Water pollution has been a crucial problem in many countries and has attracted researcher’s attention from all over the world. In a non-tidal river, from the beginning of material input, mixing and reaction, to the end of material output, the system considered should be dynamic and stochastic. The stochastic differential equation (SDE) is a theory that studies stochastic process. It can describ...

We present here a new ultrasonic diagnosis technique in natural, porous rocks. This method, based on the ultrasonic velocity changes, allows us to measure the transient spacial distribution of two liquids (water and oil) in a sandstone.

A body recovered from the water does not necessarily imply that death was due to drowning. The diagnosis of drowning is discussed together with the significance of the "diatom" and biochemical tests.
