In a Single Frequency Network (SFN), the signals coming from nearby transmitters are mixed. Since the interfering signals can be seen as (very) long term echoes, an effective method to combat echoes, such as OFDM, is a natural candidate for SFN. However, although OFDM is a very efficient method, the very long delays that characterise SFN echoes require extremely long packets in OFDM transmissio...

The myrosinase enzyme hydrolyzes glucosinolates, among which is glucoraphanin, the precursor of anticancer isothiocyanate sulforaphane (SFN). main source glucoraphanin Brassicaceae; however, its natural concentration relatively low, limiting availability SFN. An option to obtain SFN exogenous production, through enzymatic processes and under controlled conditions, allowing complete conversion W...

BACKGROUND Papillary thyroid carcinoma (PTC) is often accompanied by lymph node metastasis (LNM), compared with follicular thyroid carcinoma (FTC). Sialic acid is carried by fibronectin (sFN) as the antigen of monoclonal antibody (MoAb) JT-95 detected in 90% of PTC, and a few cases of FTC. PATIENTS AND METHODS JT-95 staining was performed in 9 PTC and 20 follicular type tumors to investigate ...

Oxidative stress is a consequence of an imbalance between reactive oxygen species (ROS) production and the ability of the cytoprotective system to detoxify the reactive intermediates. The tumor suppressor promyelocytic leukemia protein (PML) functions as a stress sensor. Loss of PML results in impaired mitochondrial complex II activity, increased ROS, and subsequent activation of nuclear factor...

The multiple–input–multiple–output (MIMO) technique is the most attractive candidate to improve the spectrum efficiency in the next generation wireless communication systems. However, the efficiency of MIMO techniques reduces in the line of sight (LOS) environments. In this paper, we propose a new MIMO data transmission scheme, which combines Single–Frequency–Network (SFN) with TDD– OFDM–MIMO a...

In this paper, field measurements carried out in a suburban SFN network with two synchronized transmitters are reported. It is found that the radio signal coverage of the distributed transmission scheme is distinctly improved when compared to a single transmitter system. The path loss gain and improvement associated to the SFN scheme are obtained as well as the multipath channel parameters incl...

In this pilot study we define and apply a methodology for building an event extraction system for the Swedish scientific medical and clinical language. Our aim is to find and describe linguistic expressions which refer to medical events, such as events related to diseases, symptoms and drug effects. In order to achieve this goal we have initiated actions that aim to extend and refine parts of t...

INTRODUCTION Fibromyalgia (FM) is a chronic syndrome characterized by widespread pain often accompanied by other symptoms suggestive of neuropathic pain. We evaluated patients for small fiber neuropathy (SFN) who were referred for fibromyalgia (FM). METHODS We studied 20 consecutive subjects with primary FM. Patients underwent neurological examination, nerve conduction studies, and skin biops...

Both Digital Audio Broadcasting (DAB) and Digital Video Broadcasting (DVB) systems use orthogonal frequency division multiplexing (OFDM) to facilitate single frequency networks (SFNs). In an SFN all transmitters transmit the same information in the same frequency block simultaneously. This transmitter diversity structure makes SFNs very efficient in fading channels with an excellent spectrum sa...

Abstract Sulforaphane (SFN), an active compound in cruciferous vegetables, has been characterized by its antiproliferative capacity. We investigated the role and molecular mechanism through which SFN regulates proliferation self-renewal of lung cancer stem cells. CD133 + cells were isolated with MACs from A549 H460 In this study, we found that inhibited simultaneously. Meanwhile, mRNA protein e...
