  1. 1. Calcium transport in the Pacific oyster, Crassostrea gigas - in a changing environment

    University dissertation from Göteborgs universitet

    Author : Kirsikka Sillanpää; Göteborgs universitet.; Gothenburg University.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Climate changes; Ussing chambers; Calcium uptake; Sodium potassium ATPase; Calcium ATPase; Sodium calcium exchanger; Calcium channel; Hemocytes; Mantle epithelium;

    Abstract : Pacific oyster, Crassostrea gigas, is globally one of the most important farmed bivalve species. A prominent features of the C. gigas is the thick CaCO3 shell covering the body of the animal and protecting it from the environment. READ MORE

  2. 2. Injectable calcium sulphate and calcium phosphate bone substitutes

    University dissertation from Department of Orthopaedics, Lund University

    Author : Malin K Nilsson; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; ortopedi; Kirurgi; Surgery; orthopaedics; traumatology; resorbable; hydroxyapatite; bone substitute; calcium phosphate; injectable; calcium sulphate;

    Abstract : Two formulations of biphasic injectable bone substitutes have been developed for the treatment of bone defects and stabilisation of fragility fractures. The first formulation consists of a calcium sulphate matrix with embedded hydroxyapatite (HA) particles to provide osteoconductivity. READ MORE

  3. 3. Calcium Homeostasis After Thyroid Surgery

    University dissertation from Department of Surgery and Gastroenterology, Lund University Hospital, SE-221 85 Lund, Sweden

    Author : Pia Lindblom; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PTH-peripheral effects; hPTH- 1-34 infusion; EDTA infusion; Set-point; Vitamin D3; PTH; Calcium; Thyroid surgery; Postoperative hypocalcemia; Bone density.; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Reduced thyroid hormones;

    Abstract : Calcium homeostasis after thyroid surgery was studied during the immediate postoperative period and after one year. One day after hemithyroidectomy ionised calcium decreased whereas basal PTH did not change. EDTA stimulated maximal and total PTH secretion and set-point decreased on postoperative day 1 and normalised on day 7. READ MORE

  4. 4. Calcium metabolism and breast cancer risk

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Martin Almquist; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; calcium; breast cancer; vitamin D; body mass index; menopause; parathyroid hormone;

    Abstract : Emerging evidence suggests that calcium and its regulating hormones, i.e. vitamin D and parathyroid hormone (PTH), affect breast cancer risk. READ MORE

  5. 5. Calcium channel activity and force regulation in smooth muscle: Effects of polyamines and growth stimulation

    University dissertation from Sölvegatan 19, S223 62 Lund

    Author : Maria Gomez; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; verapamil; tissue culture; portal vein; patch-clamp; calcium; spermidine; spermine; polyamines; excitation-contraction; smooth muscle; calcium channel; ionomycin.; Physiology; Fysiologi;

    Abstract : The initial signal for contraction in smooth muscle is an increase in [Ca2+]i. Ca2+ ions can either enter the cytosol from the extracellular medium or be released from intracellular stores. Voltage-operated Ca2+ channels (VOC) play a dominant role in the activation of smooth muscle contraction. READ MORE
