Hyaluronic Acid Present in the Tumor Microenvironment Can Negate the Pro-apototic Effect of a Recombinant Fragment of Human Surfactant Protein D on B…
2020
Copyright © 2020 Murugaiah, Agostinis, Varghese, Belmonte, Vieni, Alaql, Alrokayan, Khan, Kaur, Roberts, Madan, Bulla and Kishore. Human surfactant protein D (SP-D) belongs to the family of collectins that is composed of a characteristic amino-terminal collagenous region and a carboxy-terminal C-type lectin domain. Being present at the mucosal surfaces, SP-D acts as is a potent innate immune molecule and offers protection against non-self and altered self-such as pathogens, allergens, and tumour. Here, we examined the effect of a recombinant fragment of human SP-D (rfhSP-D) on a range of breast cancer lines. Breast cancer has four molecular subtypes characterised by varied expression of oes…
Security in Modern Smart Cities: An Information Technology Perspective
2019
In a big and modern city, the security system is not a single-layered single module system. Instead, it consists of many layers with autonomous subsystems which are capable of interfacing reciprocally in an efficient and coordinated way horizontally and vertically. The design of such indigenous subsystems and ensuring tight interaction between them while taking into account high usability and resource utilization is not a simple task. In this regard, this article provides a comprehensive overview of the security systems in smart cities. We begin by introducing trends and key stakeholders in smart cities. Next, we provide examples of mass surveillance systems in developed countries like the …
(De)legitimating electronic surveillance : a critical discourse analysis of the Finnish news coverage of the Edward Snowden revelations
2017
In 2013, ex-National Security Agency (NSA) contractor Edward Snowden shocked the world by revealing the American NSA’s (and its partners’) extensive surveillance programs. The ensuing media discussion became a focal point for the justification and contestation of surveillance in the digital age. This article contributes to the growing body of literature on the discursive construction of surveillance, concentrating on how the practice is (de)legitimized. Methodologically, the paper draws on Critical Discourse Studies, applying the concept of discourse and utilizing insights from Van Leeuwen’s categories of legitimation and social actor representation. The data come from the media coverage of…
The global flood of COVID-19 contact tracing apps: sailing with human rights and data protection standards against the wind of mass surveillance
2021
Research background: Countries all around the world are rapidly introducing contact tracing apps and other surveillance technologies to tackle the spread of COVID-19 raising serious concerns about human rights and democratic principles. Purpose of the article: The article aims to analyse how human rights and data protection law regulate the COVID-19 contact tracing apps and reveal the biggest challenges that countries face in applying the essential requirements. Methods: The article will analyse the legal framework and compare many guidance documents issued by the international organisations, including the Council of Europe, the OECD and many EU institutions on the data protection requireme…
The seroepidemiology of pertussis in Australia during an epidemic period
2006
Studying the epidemiology of pertussis and impact of differing vaccine schedules is difficult because of differing methods of case ascertainment. The advent of internationally standardized serological diagnosis for recent infection has allowed comparison of age-specific pertussis infection among European countries and was applied in Australia at the time of a major national epidemic. In 1997 and 1998, a nationally representative serum bank using residual sera from diagnostic laboratories was established. Measurement of pertussis toxin (PT) IgG level was conducted by a reference laboratory using an enzyme-linked immunosorbent assay standardized for a number of European countries. A titre of …
New insights into symptomatic or silent atrial fibrillation complicating acute myocardial infarction
2015
International audience; Atrial fibrillation (AF) is the most frequent heart rhythm disorder in the general population and contributes not only to a major deterioration in quality of life but also to an increase in cardiovascular morbimortality. The onset of AF in the acute phase of myocardial infarction (MI) is a major event that can jeopardize the prognosis of patients in the short-, medium- and long-term, and is a powerful predictor of a poor prognosis after MI. The suspected mechanism underlying the excess mortality is the drop in coronary flow linked to the acceleration and arrhythmic nature of the left ventricular contractions, which reduce the left ventricular ejection fraction. The p…
Screening and surveillance for hepatocellular carcinoma: perspective of a new era?
2016
Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third most common cause of cancer-related death with an increasing prevalence worldwide. Early diagnosis of HCC is important since observational studies have reported that, in patients undergoing surveillance, cancer is diagnosed at an earlier stage with increased chances of curative therapies. Anyway, despite the extensive use of screening for HCC, its effectiveness is still a controversial topic since supporting evidence is not unequivocal and some issues need to be explored. Areas covered: The aim of this paper is to review main literature data supporting performance and effectiveness of screening for early detection …
Surveillance for hepatocellular carcinoma with a 3-months interval in “extremely high-risk” patients does not further improve survival
2022
Abstract Background An enhanced surveillance schedule has been proposed for cirrhotics with viral etiology, who are considered at extremely high-risk of hepatocellular carcinoma (HCC). Aims We compared the 3- and 6-months surveillance interval, evaluating cancer stage at diagnosis and patient survival. Methods Data of 777 HBV and HCV cirrhotic patients with HCC diagnosed under a 3-months (n = 109, 3MS group) or a 6-months (n = 668, 6MS group) surveillance were retrieved from the Italian Liver Cancer database. Survival in the 3MS group was considered as observed and adjusted for lead-time bias, and survival analysis was repeated after a propensity score matching. Results The 3-months surveil…
European evidence based consensus for endoscopy in inflammatory bowel disease.
2013
Endoscopy plays an essential role in the diagnosis, management, prognosis, and surveillance of inflammatory bowel disease (IBD), but surprisingly there are few available guidelines.1,2 This prompted the ECCO Guidelines Committee (GuiCom) members to promote a Consensus on the appropriate indication and application of different endoscopic modalities in IBD. Since the development of guidelines is an expensive and time-consuming process, this Consensus may help to avoid duplication of effort in the future. It may also identify issues where the evidence is lacking and controlled studies are awaited. The strategy to reach the Consensus involved five steps: 1. Two members of the GuiCom (VA and RE)…
Hepatocellular cancer: optimal strategies for screening and surveillance.
2009
Hepatocellular carcinoma (HCC) is a challenging malignancy of global importance and is associated with a high rate of mortality. Individuals with chronic viral hepatitis and other forms of liver disease are at risk for developing HCC. The stage of cancer dictates the therapeutic choice, making early detection a primary objective. Many observational studies have reported that HCC is diagnosed at an earlier stage in patients who received surveillance. The guidelines of the American Association for the Study of Liver Diseases suggest that surveillance should be performed using ultrasonography at an interval of every 6–12 months. This interval is based upon mainly observational data and the exp…
