During the past few years, patients with an unidentified acute febrile illness have appeared on the wards of the New Haven Hospital. They present similar signs and symptoms. We have been unable to recognize this syndrome as that of any of the known infectious diseases.

متن کاملRegulation of water and some ions in Gammarids (Amphipods). I. Gammarus duebeni Lilljeborg from brackish water and fresh water.
Previous work on Gammarus duebeni from brackish and fresh waters established that a correlation exists between certain features of sodium regulation and the sodium concentration of the particular habitat occupied by a population. In populations from fresh water sodium losses in the urine are reduced and the transporting system at the body surface has a higher affinity for sodium ions (Sutcliffe...
متن کاملAntioxidant properties in some selected cyanobacteria isolated from fresh water bodies of Sri Lanka
Phytonutrients and pigments present in cyanobacteria act as antioxidants, which facilitate the formation of body's defense mechanism against free radical damage to cells. The aim of this investigation was to study the total phenolic content (TPC), total flavonoid content (TFC), antioxidant activity, phycobiliproteins (PBPs), and active compounds in four cyanobacterial species, that is, Oscillat...
متن کاملWater, Energy and Life: Fresh Views from the Water's Edge.
Recent observations have shown an unexpected feature of water adjacent to hydrophilic surfaces: the presence of wide interfacial zone that excludes solutes. The exclusion zone is charged, while the water beyond is oppositely charged, yielding a battery-like feature. The battery is powered by absorbed radiant energy. Implications of this energetic feature are discussed. It appears that the prese...
