Cytomegalovirus (CMV) reactivation in previously immunocompetent critically ill patients is associated with increased mortality, which has been hypothesized to result from virus-induced immunomodulation. Therefore, we studied the effects of CMV reactivation on the temporal course of host response biomarkers in patients with sepsis. In this matched cohort study, each sepsis patient developing CMV reactivation between day 3 and 17 (CMV+) was compared with one CMV seropositive patient without reactivation (CMVs+) and one CMV seronegative patient (CMVs−). CMV serostatus and plasma loads were determined by enzyme-linked immunoassays and real-time polymerase chain reaction, respectively. Systemic interleukin-6 (IL-6), IL-8, IL-18, interferon-gamma-induced protein-10 (IP-10), neutrophilic elastase, IL-1 receptor antagonist (RA), and IL-10 were measured at five time points by multiplex immunoassay. The effects of CMV reactivation on sequential concentrations of these biomarkers were assessed in multivariable
Recent advances in biomedical and sequencing technologies have revealed the genomic landscape of common forms of human cancer in unprecedented detail. Of the genes that drive tumorigenesis when altered, for most cancers it is believed that there exist a small number of
Cancer prevention has advanced tremendously in the past few decades, driven primarily by greater insights into the mechanisms of early stages of neoplastic development as well as progress in the screening, early detection, and surgical removal of precancerous lesions and cancer. The area of chemoprevention, however, has seen slower and less steady progress. Though we now have refined insights into disease pathogenesis, successful risk assessments and new risk models, as well as the established efficacy of 13 agents approved for the treatment of precancerous lesions and cancer risk reduction (1), progress has been hindered by a lack of validated biomarkers of risk and interventive response. The identification and development of accurate, reliable, and easily measurable risk and response biomarkers within the field of cancer prevention could dramatically alter our approach to the disease. Confirmed risk biomarkers would allow us to more precisely predict who will develop cancer and, therefore, who ...
Tissue imaging of treatment-induced metabolic changes is useful for optimizing cancer therapies, but commonly used methods require trade-offs between assay sensitivity and spatial resolution. Nanostructure-Initiator Mass Spectrometry imaging (NIMS) permits quantitative co-localization of drugs and treatment response biomarkers in cells and tissues with relatively high resolution. The present feasibility studies use NIMS to monitor phosphorylation of 3′-deoxy-3′-fluorothymidine (FLT) to FLT-MP in lymphoma cells and solid tumors as an indicator of drug exposure and pharmacodynamic responses. NIMS analytical sensitivity and spatial resolution were examined in cultured Burkitts lymphoma cells treated briefly with Rapamycin or FLT. Sample aliquots were dispersed on NIMS surfaces for single cell imaging and metabolic profiling, or extracted in parallel for LC-MS/MS analysis. Docetaxel-induced changes in FLT metabolism were also monitored in tissues and tissue extracts from mice bearing drug-sensitive
Purpose: Despite major progress in the molecular characterization of ovarian cancers (OC), women with recurrent, advanced stage OC continue to be treated with cytotoxic chemotherapy agents that have poor overall response rates. This contrasts with the treatment paradigm for other cancers, where outcomes have been improved by selecting treatment based upon "actionable" genomic alteration(s) that are in drug-targetable pathways. There is a need to determine if molecular profiling for OC patients can improve treatment outcomes. Such a profile should comprehensively identify "actionable" genetic aberrations as well as measure expression levels of proteins that are drug targets/response biomarkers.. Methods: The presence of mutations or alterations [e.g., copy number (CN)] in ~200 genes was determined using a validated exon-capture sequencing platform (Foundation Medicine, Inc) and protein levels of ERBB2, EGFR, ESR1, cMET, PTEN, RB1, and p16 were measured by IHC (Caris Life Sciences and Clarient, ...

0128]The LRP-1 or LRP-2 molecules are also useful as pharmacodynamic markers. As used herein, a "pharmacodynamic marker" is an objective biochemical marker which correlates specifically with drug effects. The presence or quantity of a pharmacodynamic marker is not related to the disease state or disorder for which the drug is being administered; therefore, the presence or quantity of the marker is indicative of the presence or activity of the drug in a subject. For example, a pharmacodynamic marker can be indicative of the concentration of the drug in a biological tissue, in that the marker is either expressed or transcribed or not expressed or transcribed in that tissue in relationship to the level of the drug. In this fashion, the distribution or uptake of the drug can be monitored by the pharmacodynamic marker. Similarly, the presence or quantity of the pharmacodynamic marker can be related to the presence or quantity of the metabolic product of a drug, such that the presence or quantity of ...
I think youve missed an important point about Bayesian statistics--essentially, choosing a prior lets the statistician to formally incorporate information we already know into the analysis. This prior knowledge could come from other research papers on the topic, prior stages in the same experiment (very useful in clinical trials) or maybe just intuitive logic. Frequentists do exactly the same thing, but the difference is that they arent supposed to--it technically invalidates their results. Consider for example a placebo-controlled clinical trial. The treatment and placebo groups are never truly random--ethics dictate that we balance the two groups to look as similar as possible, because this will increase the statistical power and help us identify potential risks of treatment much sooner, potentially saving lives. At the end of the trial we get a frequentist p-value of, say, 0.05, but in reality this is wrong--we are pretty sure that because of balancing the two groups the real p-value is ...

Poisson clearly distinguished between objective and subjective probabilities in 1837.[6] Soon thereafter a flurry of nearly simultaneous publications by Mill, Ellis ("On the Foundations of the Theory of Probabilities"[7] and "Remarks on the Fundamental Principles of the Theory of Probabilities"[8]), Cournot (Exposition de la théorie des chances et des probabilités)[9] and Fries introduced the frequentist view. Venn provided a thorough exposition (The Logic of Chance: An Essay on the Foundations and Province of the Theory of Probability (published editions in 1866, 1876, 1888))[10] two decades later. These were further supported by the publications of Boole and Bertrand. By the end of the 19th century the frequentist interpretation was well established and perhaps dominant in the sciences.[6] The following generation established the tools of classical inferential statistics (significance testing, hypothesis testing and confidence intervals) all based on frequentist ...

Alternatively, the frequentist multivariate solutions contain approximations and assumptions that are not stated explicitly or confirmed when the strategies are applied (see discussion on meta-analysis designs over). As an example, the mvmeta bundle for Stata allows community meta-analysis inside of a frequentist framework.[63] Nevertheless, if there isnt a prevalent comparator while in the network, then this should be managed by augmenting the dataset with fictional arms with higher variance, which isnt pretty objective and involves a call as to what constitutes a adequately large variance ...

Understanding the impact of BRAF signaling inhibition in human melanoma on key disease mechanisms is important for developing biomarkers of therapeutic response and combination strategies to improve long term disease control. This work investigates the downstream metabolic consequences of BRAF inhibition with vemurafenib, the molecular and biochemical processes that underpin them, their significance for antineoplastic activity and potential as non-invasive imaging response biomarkers.1H NMR spectroscopy showed that vemurafenib decreases the glycolytic activity of BRAF mutant (WM266.4 and SKMEL28) but not BRAFWT (CHL-1 and D04) human melanoma cells. In WM266.4 cells, this was associated with increased acetate, glycine and myo-inositol levels and decreased fatty acyl signals, while the bioenergetic status was maintained. 13C NMR metabolic flux analysis of treated WM266.4 cells revealed inhibition of de novo lactate synthesis and glucose utilization, associated with increased oxidative and ...
PGX (PolyGlycopleX) is a precise blend of naturally occurring water-soluble polysaccharides (fibers) that together, have highly unique and desirable properties for weight loss and overall good health. PGX is the result of extensive research by the University of Toronto and the Canadian Center for Functional Medicine. PGX is the worlds most viscous soluble fiber blend. What does viscous mean? Simply to thicken. Once PGX is added to water or food it thickens or becomes viscous. The viscosity of soluble fiber is important as it relates directly to the overall health benefits. The most important advantage of PGX over other soluble fiber products is that significantly less PGX is required to obtain the same important health benefits, including appetite control and reduced food cravings. Why take PGX? PGX has been clinically proven to: - Reduce appetite comfortably and safely - Reduce food cravings - Balance metabolism - Improve regularity - Maintain glucose levels already within normal range
PGX, the short-form of PolyGlycopleX, is a form of fiber that is sold either on its own or as a supplement for weight loss in many major stores.
Press Release issued Dec 22, 2014: One of the major breakthroughs that genetic testing has paved way for includes Personalized Medicine. Personalized medicine is the use of new methods of molecular analysis for better management of a patients disease or predisposition towards a disease. PGx, the study of variations of DNA and RNA characteristics as related to drug response, is one of the most exciting areas of personalized medicine today. Patients typically have variability in response to many drugs that are currently available. PGx seeks to understand how differences in genes and their expression affect the bodys response to medications. Such approaches promise the advent of Personalized Medicine in which drugs and drug combinations are optimized for each individuals unique genetic makeup.

This category is for sites about the closely related fields of pharmacogenetics and pharmacogenomics. Both involve themselves with the variation in drug reaction and expression in individuals with different genetic makeup; pharmacogenetics considers the influence of one or several individual genes, whereas pharmacogenomics deals with the entire genome.
Pharmacogenomics is the mixture of pharmaceuticals and genetics. This field has very bright future. It provides methods of drug insertion by knowing the variations in the structures of proteins and DNA.

wikilink,Bayesian probability}} {{arbitallink,https://arbital.com/p/bayes_rule_probability/,Bayes rule: Probability form}} Bayesian probability represents a level of certainty relating to a potential outcome or idea. This is in contrast to a [[Wikipedia:Frequentist_inference,frequentist]] probability that represents the frequency with which a particular outcome will occur over any number of trials. An [[Wikipedia:Event (probability theory),event]] with Bayesian probability of .6 (or 60%) should be interpreted as stating "With confidence 60%, this event contains the true outcome", whereas a frequentist interpretation would view it as stating "Over 100 trials, we should observe event X approximately 60 times." The difference is more apparent when discussing ideas. A frequentist will not assign probability to an idea; either it is true or false and it cannot be true 6 times out of 10. ==Blog posts== *[http://lesswrong.com/lw/1to/what_is_bayesianism/ What is Bayesianism?] ...

Itd be interesting to know whether you think theres anything essential I missed, though. Youve probably seen the word Bayesian used a lot on this site, but may be a bit uncertain of what exactly we mean by that. You may have read the intuitive explanation [http://www.yudkowsky.net/rational/bayes/], but that only seems to explain a certain math formula. Theres a wiki entry about Bayesian [http://wiki.lesswrong.com/wiki/Bayesian], but that doesnt help much. And the LW usage seems different from just the Bayesian and frequentist statistics thing, too. As far as I can tell, theres no article explicitly defining whats meant by Bayesianism.

In even more latest years, there are illustrations where gene phrase signatures and particular hereditary adjustments have got been important to healing decisions (Chapman et al., 2011; Paez et al., 2004). Nevertheless, accurate personalization of therapy continues to be an difficult objective in most situations. In all as well many situations, cancers sufferers present small advantage from therapy. Furthermore, it is certainly most likely that many tumors possess unrecognized awareness to agencies for which there is certainly merely no useful predictive biomarker to inform therapy decisions (Janne and Garraway, 2012; Haibe-Kains et al., 2013). In this period of developing healing choices, there is certainly a equivalent developing want for predictive biomarkers ...

Over the past decade, a number of the worlds respected companies have collapsed. A factor was these companies approach to risk management. Two different views have evolved on how risk should be assessed. The first - the frequentist view - is based on historical data. The second, or Bayesian, considers risk to be in part a judgment of the observer. Many measures are being deployed to prevent future crises - a shift from frequentist to Bayesian risk management should be part of this effort.. ...
