Aim. To determine the characteristics of megajournal authors, the nature of the manuscripts they are submitting to these journals, factors influencing their decision to publish in a megajournal, sources of funding for article processing charges (APCs) or other fees and their likelihood of submitting to a megajournal in the future. Methods. Web-based survey of 2,128 authors who recently publishe...
Some of the aromatic 'essential' oils used in aromatherapy do have well-documented therapeutic actions. However, many of the oils for which aromatherapists claim physiological medical activity, in fact possess no recorded historical medicinal actions. Oils such as: Moroccan chamomile, Citronella, Clary sage, Geranium, Rosewood, Vetiver and Ylang were originally produced solely for the perfumery...
Serial analysis of gene expression (SAGE) is a method for identifying and quantifying transcripts from eukaryotic genomes. Since its invention, SAGE has been widely applied to analyzing gene expression in many biological and medical studies. Vast amounts of SAGE data have been collected and more than a thousand SAGE-related studies have been published since the mid-1990s. The principle of SAGE ...
In Daoism, 'Sheng Ren' or 'Perfect Man' is assigned to a person who acts in accordance with Dao and nature. A sage person is wholly in harmony with Dao and therefore, the most significant description of him is manifested as 'Wu-wei' or 'non-action'. Dao is the being which natural and spontaneous process of all the things is depended to it. Therefore, no one should put obstacles in the way of Da...
y In this paper, a space-alternating generalized expectation-maximization (SAGE) algorithm is presented for the numerical computation of maximum-likelihood (ML) and penalized maximum-likelihood (PML) estimates of the parameters of covariance matrices with linear structure for complex Gaussian processes. By using a less informative hidden-data space and a sequential parameter-update scheme, a SA...
Abstract The aim of the current study was to analyze stability rosmarinic acid in ethanolic tinctures lemon balm ( Melissa officinalis L.), oregano Origanum vulgare peppermint Mentha x piperita ), rosemary Rosmarinus sage Salvia and thyme Thymus vulgaris L.). High-performance liquid chromatography with diode-array detection (HPLC–DAD) employed monitor concentration marker compound over a six mo...
Serial Analysis of Gene Expression, or SAGE, is a technology of measuring the expression levels of the mRNA transcripts. The result of a SAGE experiment is reported as a SAGE library, which contains the counts of various short segments (tags) of the cDNA clones. Through a close examination of the SAGE experiment protocol, we derive a new statistical model for the SAGE data, and give new tests f...
A comparison study of short SAGE versus GeneChip and long SAGE was conducted to determine if data were interchangeable between the techniques. Although SAGE and Affymetrix chip expression levels showed a significant correlation using the set of genes for which there was reliable and unambiguous mapping from tag-to-gene identification, correlation coefficients were low (0.51 for the Spearman's c...
A gene's expression pattern provides clues to its role in normal physiology and disease. To provide quantitative expression levels on a genome-wide scale, the Cancer Genome Anatomy Project (CGAP) uses serial analysis of gene expression (SAGE). Over 5 million transcript tags from more than 100 human cell types have been assembled. To enhance the utility of this data, the CGAP SAGE project create...
FoxA transcription factors play major roles in organ-specific gene expression, regulating, for example, glucagon expression in the pancreas, GLUT2 expression in the liver, and tyrosine hydroxylase expression in dopaminergic neurons. Organ-specific gene regulation by FoxA proteins is achieved through cooperative regulation with a broad array of transcription factors with more limited expression ...
