Sirtuin activators and inhibitors (2012)

Sirtuins 1-7 (SIRT1-7) belong to the third class of deacetylase enzymes, which are dependent on NAD(+) for activity. Sirtuins activity is linked to gene repression, metabolic control, apoptosis and cell survival, DNA repair, development, inflammation, neuroprotection, and healthy aging. Because sirtuins modulation could have beneficial effects on human diseases there is a growing interest in the discovery of small molecules modifying their activities. We review here those compounds known to activate or inhibit sirtuins, discussing the data that support the use of sirtuin-based therapies. Almost all sirtuin activators have been described only for SIRT1. Resveratrol is a natural compound which activates SIRT1, and may help in the treatment or prevention of obesity, and in preventing tumorigenesis and the aging-related decline in heart function and neuronal loss. Due to its poor bioavailability, reformulated versions of resveratrol with improved bioavailability have been developed (resVida, Longevinex(®) , SRT501). Molecules that are structurally unrelated to resveratrol (SRT1720, SRT2104, SRT2379, among others) have been also developed to stimulate sirtuin activities more potently than resveratrol. Sirtuin inhibitors with a wide range of core structures have been identified for SIRT1, SIRT2, SIRT3 and SIRT5 (splitomicin, sirtinol, AGK2, cambinol, suramin, tenovin, salermide, among others). SIRT1 inhibition has been proposed in the treatment of cancer, immunodeficiency virus infections, Fragile X mental retardation syndrome and for preventing or treating parasitic diseases, whereas SIRT2 inhibitors might be useful for the treatment of cancer and neurodegenerative diseases.

Static RRC Timeouts for Various Traffic Scenarios (2007)

The operator of an UMTS radio access network has to define timeout thresholds for the radio resource control protocol. These timeouts have a strong influence on the quality of service of the user traffic. In general long timeouts favour the call setup time over the outage probability. For short timeouts it is the other way around. Furthermore the reached quality of service level depends on the load in the system. The load consists of the number of users in the system and the services they are using. This paper investigates the relationship between these both parameters and the previously mentioned quality of service parameters. We present results of five different timeout settings, tested in various network settings. Simulations show that very high timeout values have an insignificant influence on call setup time but increase the outage. We highlight two timeout settings which fits the requirements on user experience and operators expectations best.
Renin-angiotensin system blockade: time for a reappraisal? (2014)

This editorial refers to ‘Aliskiren alone or with other antihypertensives in the elderly with borderline and stage 1 hypertension: the APOLLO trial’[†][1], by K.K.Teo et al. , on page 1743 and ‘Renin–angiotensin system antagonists and clinical outcomes in stable coronary artery disease without heart failure’[‡][2], by E. Sorbets et al. , on page 1760. 

A series of randomized clinical trials demonstrated that when compared with placebo, angiotensin-converting enzyme (ACE) inhibitiors or angiotensin receptor blockers (ARBs) were drugs able to improve the prognosis of patients with heart failure accompanied by low ejection fraction, patients with a myocardial infarction (MI), and patients with chronic kidney disease (CKD; most notably demonstrated by ARBs in diabetic nephropathy), allowing the recognition by Guidelines that blockade of the renin–angiotensin system (RAS) must be used in all these situations. The use of ACE inhibitors and also of ARBs was later expanded to patients with an increased global cardiovascular (CV) risk, patients with stable coronary artery disease (CAD), diabetic patients independently of the presence of established CV or renal disease, and hypertensive patients if clustering of CV risk factors or target organ damage was present. Table 1 lists the different clinical situations where RAS blockade is indicated according to Guidelines that led to the wide use of ACE inhibitors and ARBs in clinical practice; as an example, either alone or in combination, these drugs are prescribed in > 30–40% of the hypertensive population.1

Hematopoiesis: an overview. (1991)

Pluripotent stem cells in bone marrow are capable of proliferating (self-renewal) or of differentiating into common erythrocyte, megakaryocyte, myeloid, and lymphoid progenitor cells. During progressive differentiation, cells develop functional characteristics of their specific lineage and lose their capacity for self-renewal. A variety of growth factors, including colony-stimulating factors, stimulate hematopoiesis, and some increase the functional ability of mature cells. Understanding the characteristics of the various hematopoietic growth factors, especially the cells they affect, is essential to the oncology nurse's skilled management of patients who are myelosuppressed.
<i>Ruminococcus bromii</i> is a keystone species for the degradation of resistant starch in the human colon (2012)

The release of energy from particulate substrates such as dietary fiber and resistant starch (RS) in the human colon may depend on the presence of specialist primary degraders (or 'keystone species') within the microbial community. We have explored the roles of four dominant amylolytic bacteria found in the human colon in the degradation and utilization of resistant starches. Eubacterium rectale and Bacteroides thetaiotaomicron showed limited ability to utilize RS2- and RS3-resistant starches by comparison with Bifidobacterium adolescentis and Ruminococcus bromii. In co-culture, however, R. bromii proved unique in stimulating RS2 and RS3 utilization by the other three bacterial species, even in a medium that does not permit growth of R. bromii itself. Having previously demonstrated low RS3 fermentation in vivo in two individuals with undetectable populations of R. bromii-related bacteria, we show here that supplementation of mixed fecal bacteria from one of these volunteers with R. bromii, but not with the other three species, greatly enhanced the extent of RS3 fermentation in vitro. This argues strongly that R. bromii has a pivotal role in fermentation of RS3 in the human large intestine, and that variation in the occurrence of this species and its close relatives may be a primary cause of variable energy recovery from this important component of the diet. This work also indicates that R. bromii possesses an exceptional ability to colonize and degrade starch particles when compared with previously studied amylolytic bacteria from the human colon.
Electron-spin-resonance studies of pyrrole polymers: Evidence for bipolarons (1983)

ESR measurements have been performed on samples of neutral polypyrrole, polypyrrole-perchlorate, oxygen-doped polypyrrole, and poly($\ensuremath{\beta}$,${\ensuremath{\beta}}^{\ensuremath{'}}$-dimethylpyrrole perchlorate). A narrow Lorentzian line is observed in oxidized, highly conducting films, but no correlation between conductivity and either linewidth or intensity is found. Electrochemically cycled films, which remain highly conducting, show little or no detectable ESR absorption. It is deduced that the ESR signal seen in the as-prepared material does not arise from the current-carrying species, but rather from accidental neutral $\ensuremath{\pi}$-radical defects. The absence of paramagnetism in the metallic state is discussed within the framework of bipolaron formation.
Good Clinical Practice ( <scp>GCP</scp> ) (2005)

Abstract Good Clinical Practices (GCPs) are international ethical and quality standards for the design, conduct, performance, monitoring, auditing, analysis, recording, reporting, and regulation of clinical investigations. Clinical investigations are experiments in which a medical product such as a drug is administered or dispensed to, or used involving, one or more human subjects. These standards provide assurance that the rights and confidentiality of the trial subjects are protected and that the data and reported results are credible and accurate.
Properties of ZnS thin films prepared by 248-nm pulsed laser deposition (1993)

Pulsed laser deposition (PLD) from a hot pressed manganese doped ZnS target using a KrF laser, has produced a high rate deposition method for growing luminescent thin films. Good stoichiometric quality and typical luminescent crystal structures have been observed with a predominant hexagonal phase and little evidence of the cubic phase. The luminescent characteristics were determined by cathodoluminescence and photoluminescence excitation and stable electroluminescence was observed under pulsed dc conditions with a minimum brightness of 150 cd/m2. PLD film characteristics are compared with those observed in radio-frequency sputtered samples.

Estimating respiratory rate from instantaneous frequencies of long team heart rate tracings (2002)

Presents a method based on non-stationary state space modelling for the evaluation of the respiratory rate through the dynamical analysis of the instantaneous frequencies of heart-rate (HR). In practice, long term HR recordings are sequentially scanned by a sliding 20-sec window. Within each window, data are modelled using a singular value decomposition (SVD) based approach and the most important instantaneous frequencies, contained in the signals are estimated (the oscillation linked to the respiration is the 3rd lowest frequency). The presented method was tested by analysing 3 long term HR tracings (each lasting more than one hour) recorded in unrestrained subjects. Simultaneous direct recordings of the respiratory activity were performed and the data were used for comparing the algorithm performances. The obtained results indicate that the proposed algorithm is robust and efficient for the calculation of the instantaneous frequencies and may be a valuable tool for the estimation of the respiratory activity.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Evidence for Millennial-Scale Climate Change During Marine Isotope Stages 2 and 3 at Little Lake, Western Oregon, U.S.A. (2001)

Abstract Pollen and geochemical data from Little Lake, western Oregon, suggest several patterns of millennial-scale environmental change during marine isotope stage (MIS) 2 (14,100–27,600 cal yr B.P.) and the latter part of MIS 3 (27,600–42,500 cal yr B.P.). During MIS 3, a series of transitions between warm- and cold-adapted taxa indicate that temperatures oscillated by ca. 2°–4°C every 1000–3000 yr. Highs and lows in summer insolation during MIS 3 are generally associated with the warmest and coldest intervals. Warm periods at Little Lake correlate with warm sea-surface temperatures in the Santa Barbara Basin. Changes in the strength of the subtropical high and the jet stream may account for synchronous changes at the two sites. During MIS 2, shifts between mesic and xeric subalpine forests suggest changes in precipitation every 1000–3000 yr. Increases in Tsuga heterophylla pollen at 25,000 and 22,000 cal yr B.P. imply brief warmings. Minimum summer insolation and maximum global ice-volumes during MIS 2 correspond to cold and dry conditions. Fluctuations in precipitation at Little Lake do not correlate with changes in the Santa Barbara Basin and may be explained by variations in the strength of the glacial anticyclone and the position of the jet stream.
GroupMark : a www recommender system combining collaborative and information filtering (2000)

The objective of the SELECT project is to help Internet users find the most reliable, valu- able, important and interesting information quickly and easily, hence reducing information over- load. In these ways, SELECT will make a positive contribution to the problem of helping users tailor their information environments to meet their individual needs. The approach adopted in SELECT is to develop a general architecture for information filtering and recommendation systems, and to use this to implement and evaluate different strategies and techniques. In this paper we describe GroupMark, a prototype of a SELECT -based social recommendation tool for the WWW that is based upon shared bookmarks. We focus in particular on how GroupMark seeks to combine con- tent-based and collaborative filtering techniques, and on the user interface issues raised by recom- mendation tools: i.e., the mechanisms for controlling behaviour and the visualisation of results.

Evaluation of a colour reference box as an aid for identification of colour appearance in rooms (2000)

Hitherto, methods for visual assessment of colour appearance have not been developed for use in the study of rooms. We seek a practical method that allows one or two observers to characterize a room by identifying the perceived colours. Verbal descriptions are necessary, but lack precision. A magnitude estimation method may enable a more precise location in colour space. However, the need of a group of well-trained observers makes it impractical for room studies. A method involving matches between reference colour samples and the perceived room colours would be ideal. But, reference colour samples require a standard illumination; otherwise, the sample changes colour due to different room light. Hence, a method involving a colour reference box was developed. The colour reference box with its standard source of illumination provides a reference situation, where colour samples can be visually compared with the colours of the room. The study presented is an evaluation of this colour reference box. The crucial problem is that the same color sample in the box is perceived differently, as the observer adapts to various lighting conditions. The aim of the study was to investigate if these different perceptions of the samples could be described and controlled. In the study, 18 observers were asked to visually assess the hue of 15–66 samples, and mark its place in the NCS hue circle. The assessment of the samples was made in two different room lights: incandescent light and simulated daylight. The result of the study showed a clear tendency for the samples, perceived in the box, to shift colour in simulated daylight compared to incandescent light. It was concluded that the problem with the observer's adaptation to the room light can be described and controlled, although complementary studies are needed to quantify the adaptation effect with more accuracy, and to investigate differences in nuance. Thus, it seems that the colour reference box can be used to visually evaluate and describe the differences in colour appearance in different rooms. © 2000 John Wiley & Sons, Inc.
