technologiesComments? Revisions? Suggestions? mchitty@healthtech.com Last revised December 27, 2001  There appears to have been
a remarkable increase since last year in the prominence of what might loosely
be termed "omic" research in biology … "omics" would be the study of entities
in aggregate, in this case the DNA, RNA, protein, or other molecular complement
of a cell, tissue, or organism … Despite obvious excitement about the genome
project, some referees, editors, site visitors, and study sections have
tended to disparage other omic studies as "fishing expeditions" … That
bias has been dissipating (although not rapidly enough) because of the
growing realization that we will have to understand our favorite biological
molecules in the context of many thousands of others … omic research should
be viewed as synergistic with the more traditional studies of single molecules.
The two approaches to science require similar creativity, judgment, and
technical rigor. [John N. Weinstein “Fishing Expeditions” Science

of the host organism in a biome is an operational definition for the "function"
of the gene (in that context). [George Church Lab, Harvard University, US]

[Cellomics, Inc.] chronome: Derived from chronos
(time), nomos (rule, law) and in the case of biological chronomes,
chromosome, describes features in time, just as cells characterize the spatial
organization of life. The chronome complements the genome (derived from gene and
chromosome). The chronome consists of 1) a partly genetic, partly developmental,
partly environmentally influenced or synchronized spectrum of rhythms; 2)
stochastic or deterministic chaos; 3) trends with growth, development,
maturation and aging in health and/or trends with an elevation of disease risk,
illness and treatment in disease; and 4) unresolved variability. The chronome is
genetically coded: it is environmentally synchronized by cycles of the socio-
ecologic habitat niche and it is influenced by the dynamics of the
interplanetary magnetic field. The chronome constituents, the chrones,
algorithmically formulated endpoints, are inferentially statistically validated
and resolved by the computer. Chronomes and their chrones 1) quantify normalcy,
allowing an individualized positive health quantification; 2) assess, by their
alterations, the earliest abnormality, including the quantification of an
elevated risk of developing one (or several) disease(s), chronorisk, by the
alteration of one or several chrones; and 3) provide, by the study of underlying
mechanisms, a rational basis in the search for measures aimed at the prevention
of any deterioration in properly timed, mutually beneficial
environmental-organismic interactions. [Franz Halberg et. al "The Story Behind: Chronome/chrone"

chronomes, including, with an ever broader spectrum of rhythms, also deterministic and other chaos and trends. Chronomics thus resolves the otherwise impenetrable "normal range" of physiological variation and leads to new, dynamic maps of normalcy and health in all fields of human endeavor, including, with health care, physics, chemistry, biology, and even sociology and economics.

corpora cardiaca [of insects, the endocrinological equivalent of the

MALDI- TOF and electrospray ionization double quadrupole time of flight
(ESI-Qq-TOF) mass spectrometric technologies. The results were compared with earlier results of conventional
sequencing methods and immunocytochemical methods. In addition to many known
peptides, several m/z signals corresponding to putative novel peptides were observed in the
corpora cardiaca and/or pars intercerebralis. Furthermore, for a number of peptides evidence was provided about their localization and
MALDI- TOF analysis of the released material from the corpora cardiaca yielded information on the hormonal status of particular brain peptides.

Although there are many technologies and strategies that can be used to detect genetic factors influencing complex diseases, these technologies and strategies have inherent limitations.
... Ultimately, both the detection and precise characterization of a factor's contribution to a complex disease are difficult undertakings, because the effect of any one factor may be obscured or confounded by other factors. However, the genetic dissection of complex diseases can be greatly facilitated by paying heed to two very basic distinctions. The first distinction is between complexity at the level of individuals and complexity at the level of populations. The second distinction is between the two sequentially pursued components of gene discovery paradigms: gene identification and gene effect characterization. Although genetic epidemiology, as a research field, is oriented to both components of gene discovery for complex diseases, it is suited to gene effect characterization at the population level more than anything else. This paper reviews the origins of the genetic basis of complex traits, as well as the problems plaguing genetic epidemiologic analysis strategies, with the hope of showing how greater attention to these distinctions, as well as a greater integration of relevant knowledge, can alleviate confusion and shape future investigations. In addition, a new discipline, "phenomics" or "phenometrics," could be initiated that would complement genomic research as presently performed.

essential goals: (i) to develop and implement methodologies for identifying and

We introduce here the notion of 'ribonomics' to describe the search for the distribution of and eventually the determination of the physiological roles of these RNA structures found in the sequence databases. The utility of this approach is illustrated here by the identification in the GenBank database of RNA motifs having known binding or chemical activity. The frequency of these motifs indicates that most have originated from evolutionary drift and are selectively neutral. On the other hand, their distribution among species and their location within genes suggest that the destiny of these motifs may be more elaborate.

alternative nutrient resources. The best-studied representative of this genus is
Bacillus subtilis. In particularly, the progress on the characterization

protein secretion pathways was facilitated by the availability of the complete
genome sequence of B. subtilis (Kunst et al., 1997). Because exported
proteins are usually synthesized as precursors with an amino- terminal
hydrophobic signal peptide the genome sequence made it possible to predict all
secreted proteins of this eubacterium (Tjalsma et al., 2000 Signal peptide-

all the proteins encoded in the genome (Gaasterland 1999, Doolittle 2000). In
this context, it is equivalent to what some refer to as the orfeome, i.e.
the set of genes excluding non- coding regions. Experimentalists, especially
those involved in large- scale experiments such as expression
analysis and 2D electrophoresis,
favor a second definitions. Here it is used to describe the actual cellular
contents of proteins, taking into account the different levels of protein
concentrations (Yates 2000). We prefer the former definition for proteome, and
