text: Single molecule experiments provide insight into the individuality of biological
macromolecules, their unique function, reaction pathways, trajectories and molecular
interactions. The exceptional signal-to-noise ratio of the atomic force microscope
allows individual proteins to be imaged under physiologically relevant conditions
at a lateral resolution of 0.5–1 nm and a vertical resolution of 0.1–0.2 nm. Recently,
it has become possible to observe single molecule events using this technique.
This capability is reviewed on various water-soluble and membrane proteins. Examples
of the observation of function, variability, and assembly of single proteins are
discussed. Statistical analysis is important to extend conclusions derived from
single molecule experiments to protein species. Such approaches allow the classification
of protein conformations and movements. Recent developments of probe microscopy
techniques allow simultaneous measurement of multiple signals on individual macromolecules,
and greatly extend the range of experiments possible for probing biological systems
at the molecular level. Biologists exploring molecular mechanisms will benefit
from a burgeoning of scanning probe microscopes and of their future combination
with molecular biological experiments.

text: Quantitative real-time PCR represents a highly sensitive and powerful technique
for the quantitation of nucleic acids. It has a tremendous potential for the high-throughput
analysis of gene expression in research and routine diagnostics. However, the
major hurdle is not the practical performance of the experiments themselves but
rather the efficient evaluation and the mathematical and statistical analysis
of the enormous amount of data gained by this technology, as these functions are
not included in the software provided by the manufacturers of the detection systems.
In this work, we focus on the mathematical evaluation and analysis of the data
generated by quantitative real-time PCR, the calculation of the final results,
the propagation of experimental variation of the measured values to the final
results, and the statistical analysis. We developed a Microsoft Excel-based software
application coded in Visual Basic for Applications, called Q-Gene, which addresses
these points. Q-Gene manages and expedites the planning, performance, and evaluation
of quantitative real-time PCR experiments, as well as the mathematical and statistical
analysis, storage, and graphical presentation of the data. The Q-Gene software
application is a tool to cope with complex quantitative real-time PCR experiments
at a high-throughput scale and considerably expedites and rationalizes the experimental
setup, data analysis, and data management while ensuring highest reproducibility.

text: "We give a brief overview of the current understanding of the explosion mechanism
of core collapse supernovae. Our main focus is the impact of rotation on the explosion.
Recent observations of the polarization of the light emitted by supernova explosions
indicate that there are large deviations from spherical symmetry in the very heart
of the explosion the origin of which is unknown. We use the new approach of a
three dimensional test particle based simulation to simulate the infall phase
of a supernova event. The underlying microphysics is simplified to make this computationally
possible. A systematic study of the influence of rotation mainly during the infall
phase of the collapse of a typical iron core is performed. Indications for significant
deviations from spherical symmetry are found in our very rapidly rotating models.

text: The use of advanced patch-clamp recording techniques in brain slices, such
as simultaneous recording from multiple neurons and recording from dendrites or
presynaptic terminals, demands slices of the highest quality. In this context
the mechanics of the tissue slicer are an important factor. Ideally, a tissue
slicer should generate large-amplitude and high-frequency movements of the cutting
blade in a horizontal axis, with minimal vibrations in the vertical axis. We developed
a vibroslicer that fulfils these in part conflicting requirements. The oscillator
is a permanent-magnet-coil-leaf-spring system. Using an auto-resonant mechano-electrical
feedback circuit, large horizontal oscillations (up to 3 mm peak-to-peak) with
high frequency (,90 Hz) are generated. To minimize vertical vibrations, an adjustment
mechanism was employed that allowed alignment of the cutting edge of the blade
with the major axis of the oscillation. A vibroprobe device was used to monitor
vertical vibrations during adjustment. The system is based on the shading of the
light path between a light-emitting diode (LED) and a photodiode. Vibroprobe monitoring
revealed that the vibroslicer, after appropriate adjustment, generated vertical
vibrations of <1 µm, significantly less than many commercial tissue slicers.
Light- and electron-microscopic analysis of surface layers of slices cut with
the vibroslicer showed that cellular elements, dendritic processes and presynaptic
terminals are well preserved under these conditions, as required for patch-clamp
recording from these structures.

text: A method of automatic conversion of a physical object into a three-dimensional
digital model. The method acquires a set of measured data points on the surface
of a physical model. From the measured data points, the method reconstructs a
digital model of the physical object using a Delaunay complex of the points, a
flow strcuture of the simplicies in the Delaunay complex and retracting the Delaunay
complex into a digital model of the physical object using the flow structure.
The method then outputs the digital model of the physical object.

text: 'Information in neuronal networks is thought to be represented by the rate
of discharge and the temporal relationship between the discharging neurons. The
discharge frequency of neurons is affected by their afferents and intrinsic properties,
and shows great individual variability. The temporal coordination of neurons is
greatly facilitated by network oscillations. In the hippocampus, population synchrony
fluctuates during theta and gamma oscillations (10-100 ms scale) and can increase
almost 10-fold during sharp wave bursts. Despite these large changes in excitability
in the sub-second scale, longer-term (minute-scale) firing rates of individual
neurons are relatively constant in an unchanging environment. As a result, mean
hippocampal output remains stable over time. To understand the mechanisms responsible
for this homeostasis, we address the following issues: (i) Can firing rates of
single cells be modified? (ii) Once modified, what mechanism(s) can maintain the
changes? We show that firing rates of hippocampal pyramidal cells can be altered
in a novel environment and by Hebbian pairing of physiological input patterns
with postsynaptic burst discharge. We also illustrate a competition between single
spikes and the occurrence of spike bursts. Since spike-inducing (suprathreshold)
inputs decrease the ability of strong (''teaching'') inputs to induce a burst
discharge, we propose that the single spike versus burst competition presents
a homeostatic regulatory mechanism to maintain synaptic strength and, consequently,
firing rate in pyramidal cells.'

text: In 1991, Barton and Turelli developed recursions to describe the evolution
of multilocus systems under arbitrary forms of selection. This article generalizes
their approach to allow for arbitrary modes of inheritance, including diploidy,
polyploidy, sex linkage, cytoplasmic inheritance, and genomic imprinting. The
framework is also extended to allow for other deterministic evolutionary forces,
including migration and mutation. Exact recursions that fully describe the state
of the population are presented; these are implemented in a computer algebra package
(available on the Web at http://helios.bto.ed.ac.uk/evolgen). Despite the generality
of our framework, it can describe evolutionary dynamics exactly by just two equations.
These recursions can be further simplified using a "quasi-linkage equilibrium"
(QLE) approximation. We illustrate the methods by finding the effect of natural
selection, sexual selection, mutation, and migration on the genetic composition
of a population.

text: A central problem in biology is determining how genes interact as parts of
functional networks. Creation and analysis of synthetic networks, composed of
well-characterized genetic elements, provide a framework for theoretical modeling.
Here, with the use of a combinatorial method, a library of networks with varying
connectivity was generated in Escherichia coli. These networks were composed of
genes encoding the transcriptional regulators Lacl, TetR, and lambda Cl, as well
as the corresponding promoters. They displayed phenotypic behaviors resembling
binary logical circuits, with two chemical “inputs” and a fluorescent protein
“output.” Within this simple system, diverse computational functions arose through
changes in network connectivity. Combinatorial synthesis provides an alternative
approach for studying biological networks, as well as an efficient method for
producing diverse phenotypes in vivo.

text: 'GABAergic interneurones are diverse in their morphological and functional
properties. Perisomatic inhibitory cells show fast spiking during sustained current
injection, whereas dendritic inhibitory cells fire action potentials with lower
frequency. We examined functional and molecular properties of K(+) channels in
interneurones with horizontal dendrites in stratum oriens-alveus (OA) of the hippocampal
CA1 region, which mainly comprise somatostatin-positive dendritic inhibitory cells.
Voltage-gated K(+) currents in nucleated patches isolated from OA interneurones
consisted of three major components: a fast delayed rectifier K(+) current component
that was highly sensitive to external 4-aminopyridine (4-AP) and tetraethylammonium
(TEA) (half-maximal inhibitory concentrations < 0.1 mM for both blockers),
a slow delayed rectifier K(+) current component that was sensitive to high concentrations
of TEA, but insensitive to 4-AP, and a rapidly inactivating A-type K(+) current
component that was blocked by high concentrations of 4-AP, but resistant to TEA.
The relative contributions of these components to the macroscopic K(+) current
were estimated as 57 +/- 5, 25 +/- 6, and 19 +/- 2 %, respectively. Dendrotoxin,
a selective blocker of Kv1 channels had only minimal effects on K(+) currents
in nucleated patches. Coapplication of the membrane-permeant cAMP analogue 8-(4-chlorophenylthio)-adenosine
3'':5''-cyclic monophosphate (cpt-cAMP) and the phosphodiesterase blocker isobutyl-methylxanthine
(IBMX) resulted in a selective inhibition of the fast delayed rectifier K(+) current
component. This inhibition was absent in the presence of the protein kinase A
(PKA) inhibitor H-89, implying the involvement of PKA-mediated phosphorylation.
Single-cell reverse transcription-polymerase chain reaction (RT-PCR) analysis
revealed a high abundance of Kv3.2 mRNA in OA interneurones, whereas the expression
level of Kv3.1 mRNA was markedly lower. Similarly, RT-PCR analysis showed a high
abundance of Kv4.3 mRNA, whereas Kv4.2 mRNA was undetectable. This suggests that
the fast delayed rectifier K(+) current and the A-type K(+) current component
are mediated predominantly by homomeric Kv3.2 and Kv4.3 channels. Selective modulation
of Kv3.2 channels in OA interneurones by cAMP is likely to be an important factor
regulating the activity of dendritic inhibitory cells in principal neurone-interneurone
microcircuits.'

text: Networks of GABAergic interneurons are of critical importance for the generation
of gamma frequency oscillations in the brain. To examine the underlying synaptic
mechanisms, we made paired recordings from "basket cells" (BCs) in different
subfields of hippocampal slices, using transgenic mice that express enhanced green
fluorescent protein (EGFP) under the control of the parvalbumin promoter. Unitary
inhibitory postsynaptic currents (IPSCs) showed large amplitude and fast time
course with mean amplitude-weighted decay time constants of 2.5, 1.2, and 1.8
ms in the dentate gyrus, and the cornu ammonis area 3 (CA3) and 1 (CA1), respectively
(33-34 degrees C). The decay of unitary IPSCs at BC-BC synapses was significantly
faster than that at BC-principal cell synapses, indicating target cell-specific
differences in IPSC kinetics. In addition, electrical coupling was found in a
subset of BC-BC pairs. To examine whether an interneuron network with fast inhibitory
synapses can act as a gamma frequency oscillator, we developed an interneuron
network model based on experimentally determined properties. In comparison to
previous interneuron network models, our model was able to generate oscillatory
activity with higher coherence over a broad range of frequencies (20-110 Hz).
In this model, high coherence and flexibility in frequency control emerge from
the combination of synaptic properties, network structure, and electrical coupling.

text: 'To examine possible interactions between fast depression and modulation of
inhibitory synaptic transmission in the hippocampus, we recorded from pairs of
synaptically connected basket cells (BCs) and granule cells (GCs) in the dentate
gyrus of rat brain slices at 34 degrees C. Multiple-pulse depression (MPD) was
examined in trains of 5 or 10 inhibitory postsynaptic currents (IPSCs) evoked
at frequencies of 10-100 Hz under several conditions that inhibit transmitter
release: block of voltage-dependent Ca2+ channels by Cd2+ (10 microM), activation
of gamma-amino-butyric acid type B receptors (GABA(B)Rs) by baclofen (10 microM)
and activation of muscarinic acetylcholine receptors (mAchRs) by carbachol (2
microM). All manipulations led to a substantial inhibition of synaptic transmission,
reducing the amplitude of the first IPSC in the train (IPSC1) by 72%, 61% and
29%, respectively. However, MPD was largely preserved under these conditions (0.34
in control versus 0.31, 0.50 and 0.47 in the respective conditions at 50 Hz).
Similarly, a theta burst stimulation (TBS) protocol reduced IPSC1 by 54%, but
left MPD unchanged (0.40 in control and 0.39 during TBS). Analysis of both fractions
of transmission failures and coefficients of variation (CV) of IPSC peak amplitudes
suggested that MPD had a presynaptic expression site, independent of release probability.
In conclusion, different types of presynaptic modulation of inhibitory synaptic
transmission converge on a reduction of synaptic strength, while short-term dynamics
are largely unchanged.'

text: The presynaptic Ca2+ signal is a key determinant of transmitter release at
chemical synapses. In cortical synaptic terminals, however, little is known about
the kinetic properties of the presynaptic Ca2+ channels. To investigate the timing
and magnitude of the presynaptic Ca2+ inflow, we performed whole-cell patch-clamp
recordings from mossy fiber boutons (MFBs) in rat hippocampus. MFBs showed large
high-voltage-activated Ca(2+) currents, with a maximal amplitude of approximately
100 pA at a membrane potential of 0 mV. Both activation and deactivation were
fast, with time constants in the submillisecond range at a temperature of approximately
23 degrees C. An MFB action potential (AP) applied as a voltage-clamp command
evoked a transient Ca2+ current with an average amplitude of approximately 170
pA and a half-duration of 580 microsec. A prepulse to +40 mV had only minimal
effects on the AP-evoked Ca2+ current, indicating that presynaptic APs open the
voltage-gated Ca2+ channels very effectively. On the basis of the experimental
data, we developed a kinetic model with four closed states and one open state,
linked by voltage-dependent rate constants. Simulations of the Ca2+ current could
reproduce the experimental data, including the large amplitude and rapid time
course of the current evoked by MFB APs. Furthermore, the simulations indicate
that the shape of the presynaptic AP and the gating kinetics of the Ca2+ channels
are tuned to produce a maximal Ca2+ influx during a minimal period of time. The
precise timing and high efficacy of Ca2+ channel activation at this cortical glutamatergic
synapse may be important for synchronous transmitter release and temporal information
processing.

text: Mossy fiber (MF) synapses are key stations for flow of information through
the hippocampal formation. A major component of the output of the MF system is
directed towards inhibitory interneurons. Recent studies have revealed that the
functional properties of MF-interneuron synapses differ substantially from those
of MF-CA3 pyramidal neuron synapses. Mossy-fiber-interneuron synapses in the stratum
lucidum represent a continuum of functional subtypes, in which the subunit composition
of postsynaptic AMPA receptors and NMDA receptors appears to be regulated in a
coordinated manner.

text: Hamilton's concept of local mate competition (LMC) is the standard model to
explain female-biased sex ratios in solitary Hymenoptera. In social Hymenoptera,
however, LMC has remained controversial, mainly because manipulation of sex allocation
by workers in response to relatedness asymmetries is an additional powerful mechanism
of female bias. Furthermore, the predominant mating systems in the social insects
are thought to make LMC unlikely. Nevertheless, several species exist in which
dispersal of males is limited and mating occurs in the nest. Some of these species,
such as the ant Cardiocondyla obscurior, have evolved dimorphic males, with one
morph being specialized for dispersal and the other for fighting with nest-mate
males over access to females. Such life history, combining sociality and alternative
reproductive tactics in males, provides a unique opportunity to test the power
of LMC as a selective force leading to female-biased sex ratios in social Hymenoptera.
We show that, in concordance with LMC predictions, an experimental increase in
queen number leads to a shift in sex allocation in favour of non-dispersing males,
but does not influence the proportion of disperser males. Furthermore, we can
assign this change in sex allocation at the colony level to the queens and rule
out worker manipulation.

text: 'Males of the ant Cardiocondyla show a dispersal dimorphism of a winged and
wingless morph. The loss of flight has lead to morphological reductions in the
wingless (ergatoid) males and also affected body size, eye size and pigmentation.
As ergatoid males mate exclusively inside the maternal nest, they underlie increased
male-male competition and therefore have also evolved additional changes in behaviour
and physiology: in contrast to winged males, ergatoid males are highly aggressive
towards each other and their spermatogenesis is prolonged compared to all other
hymenopteran males. In addition to these two male morphs, we found males with
an intermediate appearance. These "intermorphic" males provide a transitional
stage between normal males in most investigated morphological and physiological
parameters. As they are produced extremely rarely and only in colonies that switch
between pure ergatoid to mixed male production, we argue that they likely represent
a developmental mistake. Parallels between the determination of male morphs and
female castes (queen-worker dimorphism and worker polymorphism) might help to
understand how the large potential of phenotypic plasticity in both sexes of social
insects is realised during development.'

text: Males of the tropical ant Cardiocondyla obscurior are either wingless and
aggressive or winged and docile, and both compete for access to virgin queens
in the nest1, 2. Although the fighter males (ergatoids) attack and kill other
ergatoids, they tolerate and even attempt to mate with their winged rivals. Here
we show that the winged males avoid the aggression of wingless males by mimicking
the chemical bouquet of virgin queens, but that their mating success is not reduced
as a result. This example of female mimicry by vigorous males is surprising, as
in other species it is typically used as a protective strategy by weaker males,
and may explain the coexistence and equal mating success of two male morphs.

text: This article is a survey of research areas in which motion plays a pivotal
role. The aim of the article is to review current approaches to modeling motion
together with related data structures and algorithms, and to summarize the challenges
that lie ahead in producing a more unified theory of motion representation that
would be useful across several disciplines.
