13.6.5.4 Sideroblastic Anemia. Sideroblastic anemia is characterized by a pattern of morphological marrow abnormalities in which there is an accumulation of perinuclear granules in nucleated red blood cell precursors. These granules, referred to as siderotic granules, are a result of disordered hemoglobin synthesis.Siderite clumped isotope thermometry also has the potential to help solve longstanding questions such as the origin of the banded iron formations and hence the cycling of elements in Archean and Proterozoic times (e.g. Ohmoto et al., 2004), or to reconstruct paleoclimate from sideritic lacustrine sediments (e.g. Wittkop et al., 2014), and to ...The aim of the present study is to reconstruct sedimentary conditions of Middle Jurassic rocks that contain siderites to identify the mineral composition of the inserbeds and to recognize the ...Several lacustrine carbonate beds, each a metre-thick interval of densely packed Mn-rich sideritic micro-spherulites or Mn-rich ferroan calcite micro-spherulites, are recorded for the first time ...

An authigenic sideritic piece of secondary xylem resembling Protocupressinoxylon cupressoides (Holden) Eckhold from the Middle Jurassic of Yorkshire has been found in close association with Sewardiodendron laxum Florin in coeval deposits from Henan. Bored galleries are found in all three directions of the xylem. Some of them appear to be mended by parenchymatous tissue, while others are either ...

Wounds were treated with warm, not boiling oil. Amputations were closed with a skin flap instead of being cauterized. Ambroise Pare (1510-1590) was one of the great surgeons of the Renaissance. He found that a mixture of eggs, oil of roses and turpentine allowed wounds to heal better than scalding oil.
