Somatic embryo-like structures of strawberry regenerated <i style="mso-bidi-font-style:normal">in vitro</i> on media supplemented with 2,4-D and BAP

739-745Somatic embryo-like structures (SELS) were produced in vitro from leaf disk and petiole explants of two cultivars of strawberry (Fragaria × ananassa Duch) on Murashige and Skoog medium with different concentrations and combinations of 2,4‑dichlorophenoxyacetic acid (2,4-D), 6-benzylaminopurine (BAP) and sucrose to check the embryonic nature of these structures histologically. A large number of SELS could be regenerated in both cultivars on media with 2 - 4 mg L-1 2,4-D in combination with 0.5 - 1 mg L-1 BAP and 50 g L-1 sucrose. Histological examination of SELS revealed the absence of a root pole. Therefore these structures cannot be strictly classified as somatic embryos. The SELS formed under the tested culture conditions represent malformed shoot-like and leaf-like structures. The importance of these results for the propagation of strawberries via somatic embryogenesis is discussed

Role of susceptibility weighted imaging and evoked potential studies in early detection of neuropsychiatric manifestations in the patients with systemic lupus erythematosus

Background: Central nervous system involvement in SLE as a part of neuropsychiatric lupus is a complex diagnostic entity due to its multiple clinical presentations. Objective: This study aimed to assess the value of susceptibility weighted imaging (SWI) and neurophysiological assessment on 30 patients with SLE in order to determine the value in the early diagnosis and management of neurological manifestation of lupus. Materials and methods: Thirty patients with ACR criteria for SLE are involved in this study. Antiphospholipid antibodies, SWI, and evoked response studies were used to assess neurological involvement in SLE. Results: Eighteen patients presented with clinical neurological manifestations attributed to neurological lupus. Abnormal SWI findings were found in 16 patients. 11 SLE patients were positive for antiphospholipid. 17 patients presented with abnormal neurophysiological parameters. No correlation between individual neurophysiological disorders (NPD) and specific neuropsychiatric symptoms was observed. There was no significant correlation between the electro physiologic findings and SLE related auto antibodies. Conclusions: SWI and neurophysiological studies may provide a useful test in the evaluation and management of early neurological lupus

RDF Stores for Enhanced Living Environments: An Overview

International audienceHandling large knowledge bases of information from different domains such as the World Wide Web is a complex problem addressed in the Resource Description Framework (RDF) by adding semantic meaning to the data itself. The amount of linked data has brought with it a number of specialized databases that are capable of storing and processing RDF data, called RDF stores. We explore the RDF store landscape with the aim of finding an RDF store that sufficiently meets the storage needs of an enhanced living environment, more concretely the requirements of a Smart Space platform aimed at running on a cluster set up of low-power hardware that can be run locally entirely at home with the purpose of logging data for a reactive assistive system involving, e.g., activity recognition or domotics. We present a literature analysis of RDF stores and identify promising candidates for implementation of consumer Smart Spaces. Based on the insights provided with our study, we conclude by suggesting different relevant aspects of RDF storage systems that need to be considered in Ambient Assisted Living environments and a comparison of available solutions
