DEAL is a sixor eight-round Luby-Rackoff cipher that uses DES as its round function, with allowed key lengths of 128, 192, and 256 bits. In this paper, we discuss two new results on the DEAL key schedule. First, we discuss the existence of equivalent keys for all three key lengths; pairs of equivalent keys in DEAL-128 require about 2 DES encryptions to find, while equivalent keys in DEAL-192 an...

This paper reports the performance characteristics of a-Si detectors with Ir-192 gamma source. Imaging performance of the detector system is evaluated using contrast sensitivity over a range of material thickness of steel, signal to noise ratio, dynamic range and linearity. The radiographic sensitivity was observed over a range of thickness of steel using standard image quality indicators. Quan...

Abstract Background and Aims Current guidelines recommend that all patients with Chronic Kidney Disease (CKD) stage 3b or higher should be monitored treated for anaemia, mineral bone disorder (BMD) metabolic acidosis. We audited the prevalence management of these complications in a cohort diabetes advanced CKD. Method A retrospective audit was undertaken using KDIGO as standard necessary approv...

Accumulated evidence demonstrated that long non-coding RNAs (lncRNAs) play a pivotal role in tumorigenesis. However, it is still largely unknown how these lncRNAs were regulated by small ncRNAs, such as microRNAs (miRNAs), at the post-transcriptional level. We here use lncRNAHOTTIP as an example to study howmiRNAs impact lncRNAs expression and its biological significance in hepatocellular carci...

Strength training (ST) is considered an intervention of choice for the prevention and treatment of sarcopenia. Reports in the literature have suggested that the insulin-like growth factor I protein (IGF-I) plays a major role in ST-induced skeletal muscle hypertrophy and strength improvements. A microsatellite repeat in the promoter region of the IGF1 gene has been associated with IGF-I blood le...

PURPOSE Recently a number of hypothetical sources have been proposed and evaluated for use in brachytherapy. In the present study, a hypothetical (101)Rh source with mean photon energy of 121.5 keV and half-life of 3.3 years, has been evaluated as an alternative to the existing high-dose-rate (HDR) sources. Dosimetric characteristics of this source model have been determined following the recom...

The specific and selective proteolysis of cardiac troponin I (cTnI) has been proposed to play a key role in human ischemic myocardial disease, including stunning and acute pressure overload. In this study, the functional implications of cTnI proteolysis were investigated in human cardiac tissue for the first time. The predominant human cTnI degradation product (cTnI(1-192)) and full-length cTnI...

The Community Bureau of Reference of the European Communities has produced four batches of lyophilized serum Certified Reference Materials, two for cortisol (CRM 192 and 193) and two for progesterone (CRM 347 and 348). For cortisol, one of the pools consisted of serum from healthy blood donors, whereas the second batch was supplemented with pure cortisol. The progesterone Reference Materials co...
