Drought adaptation of a terrestrial macroscopic cyanobacterium, Nostoc flagelliforme, in arid areas: A review

  Nostoc flagelliforme is a terrestrial macroscopic cyanobacterium with a hair-like appearance that is distributed in arid and semi-arid areas. It exhibits remarkable tolerance to extremely acute or long-term dehydration stress. However, it cannot withstand prolonged hydration or water saturation. It appears that too little water limits its growth while too much water becomes a burden. This seemingly...

Seasonal variation by the onset of symptoms and health care seeking behaviour in 282 patients with Inflammatory Bowel Disease

  Environmental factors are believed to trigger the onset of Inflammatory bowel disease (IBD). We aimed to evaluate the seasonal variation in the onset of symptoms in patients with IBD and health care seeking behaviour. 282 patients were chosen from the charts. Demographic features, the month and the age at the onset of presenting symptoms and delayed diagnosis term for each patient were analyzed. Cumulative...
