Thrombocytosis describes a platelet count elevated above 450 × 109/litre, which can be (1) primary—including essential thrombocythaemia, chronic myeloid leukaemia, polycythaemia vera and myelodysplastic syndromes; or (2) secondary—including iron deficiency, infection, blood loss, malignancy. Platelets are released from megakaryocytes, whose development is principally regulated by thrombopoietin. This is chiefly produced in the liver and binds to its receptor (c-Mpl) to cause activation via the JAK-STAT signalling pathway at different levels of the platelet production pathway, ranging from the proliferation and survival of haematopoietic stem cell/progenitor cells to megakaryocyte maturation. Thrombopoietin production is increased by a wide variety of stimuli, which explains the many causes of secondary thrombocytosis....

Background: Iron deficiency is the most common nutritional disorder in the pregnant women. This study was conducted to investigate the possible contribution and impact of iron status on pregnancy in a costal population. One hundred seventy pregnant women aged between 18-38 years are taken in the current study. The women were followed up weekly till delivery after which neonatal anthropometrics and other birth out comes were recorded. Mean serum Hemoglobin, ferritin and iron were found to be lower in 3rd trimester as compared to 1st trimester, which become lower at postpartum then reach nearly to normal value during lactation. While serum ferritin was found to be lower in 2nd trimester as compared to 1st trimester, it was significantly higher in 3rd as compared to second trimesters and also decreased at postpartum and lactation. Serum TIBC, transferrin and Fe/TIBC levels increased during 1st, 2nd and 3rd trimesters, Serum TIBC also elevated at postpartum, then decreased during lactation. This result provides that, it is important to detect which form of iron become abnormal during trimesters of pregnancy, postpartum and lactation which may lead to cause of nutritional deficiency in pregnant women, so as to reduce public problem.

Base Superalloy

Recently we have been investigating a class of nickel-base superalloys which possess substantial room temperature ductility. This improvement in ductility is directly related to improvements in grain boundary strength due to increased boundary cohesion through control of detrimental impurities and improved boundary shear strength by controlled grain boundary micros true tures.For these investigations an experimental nickel-base superalloy was doped with different levels of sulphur impurity. The micros tructure after a heat treatment of 1360°C for 2 hr, 1200°C for 16 hr consists of coherent precipitates of γ’ Ni3(Al,X) in a nickel solid solution matrix.

Some authors using immunofluorescent techniques had already suggested that some hepatocytes are able to synthetize several plasma proteins. In vitro studies on normal cells or on cells issued of murine hepatomas raise the same conclusion. These works could be indications of an hepatocyte functionnal non-specialization, meanwhile the authors never give direct topographic proofs suitable with this hypothesis.The use of immunoenzymatic techniques after obtention of monospecific antisera had seemed to us useful to bring forward a better knowledge of this problem. We have studied three carrier proteins (transferrin = Tf, hemopexin = Hx, albumin = Alb) operating at different levels in iron metabolism by demonstrating and localizing the adult rat hepatocytes involved in their synthesis.Immunological, histological and ultrastructural methods have been described in a previous work.
