in the restructured environment of electricity market, firstly the generating companies and the customers are looking for maximizing their profit and secondly independent system operator is looking for the stability of the power network and maximizing social welfare. in this paper, a one way auction in the electricity market for the generator companies is considered in both perfect and imperfec...

Objective(s): Naringin has been reported to regulate bone metabolism. However, its effect on osteogenesis remains unclear. The aim was to investigate the effect of naringin on osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) through the activation of the ERK signaling pathway in osteogenic differentiation. Materials and Methods: Annexin V-FITC assay and MTT assay ...

In this paper, we determine the optimal exercise strategy for corporate warrants if investors suffer from imperfect information and we evaluate the impact of this friction on the value of a warrant. For this purpose, we address both exercises at maturity, where imperfect information about the firm value is present, and exercises before maturity which are impacted by imperfect information about ...

Amputation of the thumb invariably causes marked functional impairment of the hand especially, pinch and grasp functions. In rural areas where highly skilled microvascular surgeries are not available, distraction osteogenesis provides an easy and safe alternative of thumb reconstruction. We report a case of crush injury of the right hand in a 37 year old gentleman in which the right thumb was a...

Abstract Background Osteogenesis is tightly coupled with angiogenesis during bone repair and regeneration. However, the underlying mechanisms linking these processes remain largely undefined. The present study aimed to test hypothesis that epidermal growth factor-like domain-containing protein 6 (EGFL6), an angiogenic factor, also functions in marrow mesenchymal stem cells (BMSCs), playing a ke...

Osteogenesis Imperfecta (OI) is a genetic disorder characterized by bones that break easily, often from little or no apparent cause. In this article, we present a patient suffering from OI, who had concomitant active Behçet’s Disease(BD)with repeated oro-genital ulcers, skin postular eruptions and severe recurrent bilateral uveitis. This patient, is, to our knowledge the first reported case in ...

Our clinical files on osteogenesis imperfecta are brought up-to-date reviewing a total of 33,555 cases admitted between 4/XII/48 and 31/VIII/76. From these, 5 clinical cases were found. The extreme rareness of this regional pathology in our Cátedra y Sericio de Pediatría, which is the largest concentration center in Paraguay had led us to make this publication. From our casuistics, we may singl...

The mortality rate in cardiac surgery patients with heritable generalized connective tissue disorders, such as Marfan s syndrome and osteogenesis imperfecta, is high due to tissue friability. We describe a successful open heart surgery for repair of aortic regurgitation in a woman with osteogenesis imperfecta (OI). Although tissue friability caused no problems during surgery in this case, it sh...

A 20-yr-old primigravida at 38 weeks gestation with premature rupture of membranes and evidence of fetal distress required urgent Caesarean section. The diagnosis of osteogenesis imperfecta had been made 4 days earlier. The patient refused a regional anaesthetic. Difficulties in the administration of general anaesthesia to patients with osteogenesis imperfecta were recognized and managed accord...

A 21 year old man with severe osteogenesis imperfecta developed classic right maxillary trigeminal neuralgia. Brain imaging showed pronounced basilar invagination, which was probably responsible for the pain through distortion of the trigeminal sensory root secondary to displacement of the brainstem. Osteogenesis imperfecta may be added to Paget's disease as a potential cause of symptomatic tri...
