Headlines win elections: Mere exposure to fictitious news media alters voting behavior.

Repeatedly encountering a stimulus biases the observer's affective response and evaluation of the stimuli. Here we provide evidence for a causal link between mere exposure to fictitious news reports and subsequent voting behavior. In four pre-registered online experiments, participants browsed through newspaper webpages and were tacitly exposed to names of fictitious politicians.

Beyond Left and Right: Binding and Retrieval of Spatial and Temporal Features of Planned Actions.

There is evidence that planning an action relies on binding codes of the relevant features of that action into an action plan. Such binding is indicated by the observation that planning a novel action is impaired if it shares some but not all features with another action that is held in memory for later execution. Most previous studies have focused on the binding of the spatial features and , which are particularly salient but not the only features of intentional body movements.

Histomorphometric analysis reveals reduced bone mass and bone formation in patients with quiescent Crohn's disease.

Background & Aims: Crohn's disease (CD) is associated with an increased prevalence of osteoporosis, but the pathogenesis of this bone loss is only partly understood. We assessed bone structure and remodeling at the tissue level in patients with quiescent CD. We also investigated the roles of osteocyte density and apoptosis in CD-associated bone loss.

Investigation of bone allografts representing different steps of the bone bank procedure using the CAM-model.

Bone grafting is commonly used to treat large bone defects. Since autografts are limited and frequently associated with postoperative donor morbidity, allografts from bone banks are often used. However, vascularisation of the allograft is often impaired, resulting in inadequate bone healing and functional graft failure.

Does Weber's rotation osteotomy induce degenerative joint disease at the shoulder in the long term?

Weber's internal rotation osteotomy of the humeral head is recommended for the treatment of anteroinferior shoulder instability with a large Hill-Sachs defect. The observation of severe joint degeneration in the course of long-term follow-up provided the motivation for this study. An osteotomy was performed in 42 patients from 1984 to 1990.

Effect of raloxifene treatment on osteocyte apoptosis in postmenopausal women.

Increased osteocyte apoptosis, as the result of estrogen deficiency, could play a role in the decrease of bone mass and bone strength seen in postmenopausal osteoporosis. We investigated whether treatment with raloxifene of postmenopausal women with osteoporosis affects osteocyte apoptosis. Transiliac bone biopsies were obtained from 26 osteoporotic women at baseline and after 2 years of treatment with placebo or raloxifene.

Surgical approaches for nasal dermal sinus cysts.

Nasal midline masses of ectodermal origin include nasal dermoids (ND) and nasal dermal sinus cysts (NDSC). NDSC are characterized by an intracranial-extradural extension, while ND are limited to the nasal dorsum, medial canthus, or glabella without intracranial extension. We report our experience in 11 NDSC patients.

In vivo mechanical loading modulates insulin-like growth factor binding protein-2 gene expression in rat osteocytes.

Mechanical stimulation is essential for maintaining skeletal integrity. Mechanosensitive osteocytes are important during the osteogenic response. The growth hormone-insulin-like growth factor (GH-IGF) axis plays a key role during regulation of bone formation and remodeling.

Additional weight bearing during exercise and estrogen in the rat: the effect on bone mass, turnover, and structure.

Mechanical loading and estrogen play important roles in bone homeostasis. The aim of this study was to evaluate the effects of mechanical loading on trabecular bone in the proximal femur of ovariectomized rats. We hypothesized that mechanical loading suppresses bone resorption and increases bone formation, which differs from the suppressive effects of estrogen on both resorption and formation.

Effect of long-term growth hormone treatment on bone mass and bone metabolism in growth hormone-deficient men.

Unlabelled: Long-term GH treatment in GH-deficient men resulted in a continuous increase in bone turnover as shown by histomorphometry. BMD continuously increased in all regions of interest, but more in the regions with predominantly cortical bone.

Introduction: Adults with growth hormone (GH) deficiency have reduced rates of bone turnover and subnormal BMD.

Bone marrow stromal cells can provide a local environment that favors migration and formation of tubular structures of endothelial cells.

Findings suggest that mesenchymal progenitor cells can support the process of blood vessel formation, which may be relevant during granulation tissue formation at defect sites. The aim of this study was to investigate possible mechanisms of the angiogenic process that can be stimulated by mesenchymal progenitor cells. In the in vivo-like model of the chick embryo chorioallantoic membrane assay, we observed blood vessel ingrowth into collagen sponges containing conditioned medium from undifferentiated bone marrow stromal cells.

Histological observations on biopsies harvested following sinus floor elevation using a bioactive glass material of narrow size range.

We evaluated the bone augmenting capacity of bioactive glass particles, size range 300-355 microns (BG-particles), in human sinus floor elevations using histomorphometrical methods. A total of 10 patients underwent bilateral grafting, using a 1:1 mixture of autogenous bone particles (from iliac crest) and BG-particles at one side (experimental side), and bone particles only at the other side (control side, split mouth design). A total of 72 bone biopsies were taken at the time of fixture installation; that is, 3 patients at 4 months, 3 at 5 months and 3 at 6 months after grafting and 1 patient at 16 months (when she presented again).

Histomorphometrical analysis of bone formed in human maxillary sinus floor elevations grafted with OP-1 device, demineralized bone matrix or autogenous bone. Comparison with non-grafted sites in a series of case reports.

Bone morphogenetic proteins have proven to be effective bone inductors in animals and are therefore promising as inductors of bone formation in humans. In the present study we investigated the tissue formed after grafting osteogenic protein 1 on a collagen carrier (OP-1-device) in the human sinus floor elevation procedure. Three patients were grafted with OP-1 device.

Bone histomorphometric evaluation of pamidronate treatment in clinically manifest osteoporosis.

The effect of pamidronate therapy on bone histology was studied in patients with osteoporosis with at least one vertebral fracture in a randomized, double-masked, placebo-controlled, multi-center trial. Patients received pamidronate 150 mg/day or placebo in addition to calcium 500 mg/day and vitamin D3 400 IU/day. Transiliac bone biopsies were obtained before and after 1 or 2 years of treatment.

Histological observations of a bilateral maxillary sinus floor elevation 6 and 12 months after grafting with osteogenic protein-1 device.

Objective: The purpose of this case study was to analyze the tissue formed in a maxillary sinus, 6 and 12 months after grafting with recombinant human osteogenic protein-1 (OP-1) linked to a collagen carrier of bovine origin.

Patient And Methods: A 49-year-old woman referred for bilateral sinus floor elevation, was grafted with an OP-1 device. After 6 months, a biopsy was taken from one of the grafted areas.

Mineralization processes in demineralized bone matrix grafts in human maxillary sinus floor elevations.

For reconstruction of the severely resorbed lateral maxilla for dental implant placement, one of the successful procedures is to elevate the maxillary sinus floor by implanting demineralized bone matrix (DBM). We studied bone formation in DBM grafts in the lateral maxilla in humans by means of histology and histomorphometry. Six months after grafting, at the time of dental implantation biopsies were taken from the grafted areas of seven patients.

[Paraneoplastic cerebellar degeneration (PCD) with anti-Yo antibodies in ovarian carcinoma].

We report the case of 71-year old Caucasian woman with ovarian cancer, who developed paraneoplastic cerebellar degeneration (PCD). Pathognomonical anti Yo antibodies could be identified in serum specimens. We describe the history and clinical presentation and summarise the disease.

The effect of growth hormone (GH) on histomorphometric indices of bone structure and bone turnover in GH-deficient men.

We investigated the effects of GH on bone structure and turnover by histomorphometry in GH-deficient adults. Therefore, transiliac bone biopsies were obtained before and after 1 yr of treatment in 36 GH-deficient men (mean age, 28 +/- 4 yr). Thirteen patients had isolated GH deficiency and 23 patients had multiple pituitary hormone deficiencies.

Histomorphometric analysis of bone mass and bone metabolism in growth hormone deficient adult men.

Transiliac bone biopsies were obtained from 36 growth hormone (GH) deficient men (mean age +/- SD, 28 +/- 4 years), of which 13 had an isolated GH deficiency and 23 had partial or complete hypopituitarism. The latter group was adequately substituted for the pituitary hormone deficiencies other than GH. Static histomorphometry was compared with eight controls, and dynamic histomorphometry was compared with six healthy men matched for age.

Improvement of lipid profile in type 2 (non-insulin-dependent) diabetes mellitus by insulin-like growth factor I.

Type 2 (non-insulin-dependent) diabetes mellitus is associated with increased glucose, insulin, total and VLDL-triglyceride, and often total and LDL-cholesterol levels which promote vascular disease. Recombinant human insulin-like growth factor-I which mimics many effects of insulin, decreased insulin, total and VLDL-triglyceride, and total and LDL-cholesterol levels in healthy man as well as glucose and insulin levels in Type 2 diabetic patients. We, therefore, investigated total and fractionated triglyceride and cholesterol levels, lipoprotein(a), non-esterified fatty acid, and apolipoprotein levels in eight Type 2 diabetic patients during five control, five treatment, and three wash-out days.

A psychophysical study of work-related stress using observer ratings.

In two experimental series a panel of observers rated the perceived exertion of a worker performing different tasks. The first experiment involved the lifting of boxes of different weights. The second experiment comprised combined static and dynamic work of the assembly-line type during a full working day.

Measurement of whole-body vibration by double-pulsed holography.

A technique for registering vibration and deformation patterns has been adapted for the measurement of whole-body vibration in humans. Double-exposure holographic interferometry produces three dimensional pictures of the body, allowing exact measurement of the subject's movement between the two pulses. In this study an interval of 600 microseconds between the two pulses was used, producing measurements with a resolution of less than 0.
