Autor: Matti Välimäki, A Poranen, K. Rantakari, Risto Pelkonen, R. Tähtelä, Timo Sane

Publikováno v: The Journal of Clinical Endocrinology & Metabolism. 79:1395-1398

We studied the incidence of postoperative hyponatremia in 91 consecutive patients (44 males and 47 females; age, 45 yr; range, 12-76) operated on transsphenoidally for pituitary tumors. A postoperative serum sodium concentration less than 135 mmol/L

Publikováno v: Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA. 10(2)

Cardiac transplantation exposes recipients to osteoporosis and increased risk of consequent fractures. The purpose of the present study was to examine the magnitude, timing and mechanism of bone loss following cardiac transplantation, and to establis

Aggressive breast cancer leads to discrepant serum levels of the type I procollagen propeptides PINP and PICP

Autor: A, Jukkola, R, Tähtelä, E, Thölix, K, Vuorinen, G, Blanco, L, Risteli, J, Risteli

Publikováno v: Cancer research. 57(24)

The propeptides PICP and PINP are derived from the synthesis of type I collagen, a major matrix protein of bone and soft tissues. The aim of this cross-sectional study was to investigate their value as indicators of the aggressivity of breast cancer.

Serum concentrations of type I collagen carboxyterminal telopeptide (ICTP) and type I procollagen carboxy-and aminoterminal propeptides (PICP, PINP) as markers of metastatic bone disease in breast cancer

Autor: R, Tähtelä, E, Thölix

Publikováno v: Anticancer research. 16(4B)

The most abundant protein in bone is type I collagen. During type I collagen formation two extension peptides from both ends of the procollagen molecule, carboxy- and aminoterminal propeptides (PICP and PINP), are liberated in equimolar concentration

Nocturnal rise in markers of bone resorption is not abolished by bedtime calcium or calcitonin

Autor: Sirkka-Liisa Karonen, S. Sairanen, Kalevi Laitinen, R. Tähtelä, Matti Välimäki

Publikováno v: Calcified tissue international. 55(5)

As assessed by urine pyridinium cross-links, bone resorption increases at night. This has been ascribed to either the nocturnal rise of serum parathyroid hormone (PTH) or immobilization. ICTP is the carboxyterminal telopeptide region of type I collag

The bio/immuno ratio of plasma luteinizing hormone does not change during the endogenous secretion pulse: reanalysis of the concept using improved immunometric techniques

Autor: R. Tähtelä, Ying-Qing Ding, Ilpo Huhtaniemi, M. Välimäki

Publikováno v: The Journal of clinical endocrinology and metabolism. 75(6)

The purpose of this study was to find out whether the ratio of bioactive (B)/immunoreactive (I) LH varies during pulsatile LH secretion in healthy men when I-LH is determined using novel immunometric methods with improved sensitivity and specificity.
