The Effect of Conflict Resolution Methods on the Implemenation of IS Outsourcing
This study investigates the effect of conflict resolution methods on the IS outsourcing performance. A survey of 207 IS outsourcing relationships of U.S. firms indicates that (1) constructive/proactive methods, such as joint problem solving, is positively related to the success of IS outsourcing relationships, and that (2) destructive/passive methods, such as persuasion, smoothing/avoiding, domination, and use of harsh words are negatively related to the success of IS outsourcing relationships. The findings suggest that the manner in which conflict is resolved can be productive or destructive for the IS outsourcing performance
Acute primary gastric volvulus occurring after overeating in a 12-year-old girl
Gastric volvulus is a rare cause of recurrent abdominal pain or vomiting. This report presents a case of a 12-year-old girl with acute gastric volvulus and 2-hour history of epigastric pain after overeating. Computed tomography showed severe gastric distension without other abnormal findings. The gastric fluid decompressed through a nasogastric tube was approximately 4,000 mL in volume and non-bilious in color. Upper gastrointestinal series showed organo-axial volvulus without intestinal malrotation. Emergency laparotomy was performed. Because the color of stomach was pinkish, detorsion of the volvulus and gastropexy was performed. Postoperatively, the girl recovered uneventfully
EFFECT OF BALLET-EXPERIENCE OF 12-YEAR-OLD FEMALE CHILDREN ON THE LEARNING OF DYNAMIC BALANCE CONTROL
The purpose of this study was to examine whether previous regular experience in ballet enhance the learning balance task on the balance testing board. Eighteen healthy female children aged twelve including eight with more than three years ballet-experience and eight without the ballet-experience participated. Dynamic balance learning consisting of 3 sessions, which were pre-training and post-training with practices, and retention with no practice, were performed on the balance testing board. The interval between each session was one week. The stability was measured while the subject performed balance task on the same balance testing board placed on an AMTI force platform. The stability was defined as the sum of center of pressure (COP) and center of body mass (COM) mono directional displacements; and the variance of the end tip of the balance board displacement in vertical direction. Two way ANOVA for repeated-measures (2 groups 3 sessions) revealed statistically significant increases in postural stability for the test immediately following training and the retention test in both groups. Although interaction effect indicated greater improvement in non-experienced group, the stability of the group with experience in ballet far exceeded that of the group without experience, about all the variables of each session. Our results suggest that experience in ballet up to being twelve year old have positive influence on the learning dynamic balance control task
Nutrigenomic Functions of PPARs in Obesogenic Environments
Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that mediate the effects of several nutrients or drugs through transcriptional regulation of their target genes in obesogenic environments.This review consists of three parts. First, we summarize current knowledge regarding the role of PPARs in governing the development of white and brown/beige adipocytes from uncommitted progenitor cells. Next, we discuss the interactions of dietary bioactive molecules, such as fatty acids and phytochemicals, with PPARs for the modulation of PPAR-dependent transcriptional activities and metabolic consequences. Lastly, the effects of PPAR polymorphism on obesity and metabolic outcomes are discussed. In this review, we aim to highlight the critical role of PPARs in the modulation of adiposity and subsequent metabolic adaptation in response to dietary challenges and genetic modifications. Understanding the changes in obesogenic environments as a consequence of PPARs/nutrient interactions may help expand the field of individualized nutrition to prevent obesity and obesity-associated metabolic comorbidities
Proteomic and biochemical analyses reveal the activation of unfolded protein response, ERK-1/2 and ribosomal protein S6 signaling in experimental autoimmune myocarditis rat model
<p>Abstract</p> <p>Background</p> <p>To investigate the molecular and cellular pathogenesis underlying myocarditis, we used an experimental autoimmune myocarditis (EAM)-induced heart failure rat model that represents T cell mediated postinflammatory heart disorders.</p> <p>Results</p> <p>By performing unbiased 2-dimensional electrophoresis of protein extracts from control rat heart tissues and EAM rat heart tissues, followed by nano-HPLC-ESI-QIT-MS, 67 proteins were identified from 71 spots that exhibited significantly altered expression levels. The majority of up-regulated proteins were confidently associated with unfolded protein responses (UPR), while the majority of down-regulated proteins were involved with the generation of precursor metabolites and energy metabolism in mitochondria. Although there was no difference in AKT signaling between EAM rat heart tissues and control rat heart tissues, the amounts and activities of extracellular signal-regulated kinase (ERK)-1/2 and ribosomal protein S6 (rpS6) were significantly increased. By comparing our data with the previously reported myocardial proteome of the Coxsackie viruses of group B (CVB)-mediated myocarditis model, we found that UPR-related proteins were commonly up-regulated in two murine myocarditis models. Even though only two out of 29 down-regulated proteins in EAM rat heart tissues were also dysregulated in CVB-infected rat heart tissues, other proteins known to be involved with the generation of precursor metabolites and energy metabolism in mitochondria were also dysregulated in CVB-mediated myocarditis rat heart tissues, suggesting that impairment of mitochondrial functions may be a common underlying mechanism of the two murine myocarditis models.</p> <p>Conclusions</p> <p>UPR, ERK-1/2 and S6RP signaling were activated in both EAM- and CVB-induced myocarditis murine models. Thus, the conserved components of signaling pathways in two murine models of acute myocarditis could be targets for developing new therapeutic drugs or methods aimed at treating enigmatic myocarditis.</p
Persistent Direction-Fixed Nystagmus Following Canalith Repositioning Maneuver for Horizontal Canal BPPV: A Case of Canalith Jam
The authors report a 64-year-old man who developed persistent direction fixed nystagmus after a canalith repositioning maneuver for horizontal canal benign paroxysmal positional vertigo (HC-BPPV). The patient was initially diagnosed with right HC-BPPV given that the Dix-Hallpike test showed geotropic horizontal nystagmus that was more pronounced on the right side, although the roll test did not show any positional nystagmus. The patient was treated with a canalith repositioning maneuver (Lempert maneuver). The next day, the patient experienced a different character of dizziness, and left-beating spontaneous nystagmus regardless of head position was observed. After a forced prolonged left decubitus and frequent head shaking, his symptoms and nystagmus resolved. This condition, referred to as canalith jam, can be a complication after the repositioning maneuver in patients with BPPV. Atypical positional tests suggest that abnormal canal anatomy could be the underlying cause of canalith jam
