INTRODUCTION Osteopenia and osteoporosis because of hyperprolactinaemia caused by prolactinoma may be followed by an increased risk of fracture. There are no data on the bone effects of functional hyperprolactinaemia. The aim was to assess the influence of hyperprolactinaemia of various origins on bone turnover and density in different skeletal sites. MATERIAL AND METHODS The study was carrie...

Alkyllysophospholipids (ALP) which are 1-O-alkyl analogs of the cell membrane component 1-acyl-sn-glycero-3-phosphocholine (1-acyl-GPC) represent a family of new antitumor drugs. Susceptibility of cells to ALP is correlated to a selective inhibition of fatty acid incorporation into 1,2-diacyl-sn-glycero-3-phosphocholine in intact cells. This report examines oleoyl-CoA-1-acyl-GPC acyl-transferas...

OBJECTIVE We aimed at comparing markers of bone metabolism during unloading in young and older men, and to assess countermeasure effectiveness. METHODS 16 older (60±2 years) and 8 younger men (23±3 years) underwent bed rest (BR) for 14 days. A subgroup of the Older performed cognitive training during BR and supplemented protein and potassium bicarbonate afterwards. Biochemical markers of bone...

Bone metabolism is characterized by two opposite activities: the formation of new bone by osteoblasts and the degradation of old bone by the osteoclasts. Osteoporosis is a disease in which subtle modi cations of bone remodeling can result in a substantial loss of bone over a prolonged period of time. The needs for non-invasive techniques that can be applied more widely and repeated several time...

The 2008 World Health Organization (WHO) proposal recognizes 2 provisional indolent systemic mastocytosis (ISM) subvariants: smoldering systemic mastocytosis (SSM) and isolated bone marrow (BM) mastocytosis (BMM).1 SSM is characterized by a high burden of mast cells (MCs; Table 1), whereas BMM is defined by BM involvement without concurrent skin involvement or presence of multiorgan visceral le...

In macrophages from inbred mice, the magnitude of the interferon (IFN) response to Newcastle disease virus (NDV) infection is under genetic control of the If-1 locus, which carries the allele for either high (h) or low (l) IFN production. Here, we report that the activity of genes within the If-1 locus is influenced by macrophage-derived endogenous IFN. In addition to various other biological e...

Abstract IL-38 is an IL-1 family receptor antagonist that restricts IL-17–driven inflammation by limiting cytokine production from macrophages and T cells. In the current study, we aimed to explore its role in experimental autoimmune encephalomyelitis mice, which is, among others, driven IL-17. Unexpectedly, IL-38–deficient mice showed strongly reduced clinical scores histological markers of en...

introduction demyelination is a common lesion of spinal cord injury; cell therapy is an approach for replacing the lost oligodendrocytes. objective in this study, bone marrow stromal cells (bmscs) have been transdifferentiated into oligodendrocyte-like cells (olcs) and used in cytotherapy of contused spinal cords in rats. materials and methods the bmscs were collected from rat long bones, cultu...

This study aimed to determine the effects of administering a mixture of subchronic lead acetate (Pb (NO3)2) and cadmium chloride (CdCl2·2.5H2O) on the bone metabolism of rats. A control group and three experimental groups consisted of randomly selected rats. Rats in each experimental group were orally administered with a mixture of Pb (NO3)2 and CdCl2·2.5H2O with the following respective doses ...
