text: We address the problem of localizing homology classes, namely, finding the
cycle representing a given class with the most concise geometric measure. We focus
on the volume measure, that is, the 1-norm of a cycle. Two main results are presented.
First, we prove the problem is NP-hard to approximate within any constant factor.
Second, we prove that for homology of dimension two or higher, the problem is
NP-hard to approximate even when the Betti number is O(1). A side effect is the
inapproximability of the problem of computing the nonbounding cycle with the smallest
volume, and computing cycles representing a homology basis with the minimal total
volume. We also discuss other geometric measures (diameter and radius) and show
their disadvantages in homology localization. Our work is restricted to homology
over the ℤ2 field.

text: "Background: The availability of many gene alignments with overlapping taxon
sets raises the question of which strategy is the best to infer species phylogenies
from multiple gene information. Methods and programs abound that use the gene
alignment in different ways to reconstruct the species tree. In particular, different
methods combine the original data at different points along the way from the underlying
sequences to the final tree. Accordingly, they are classified into superalignment,
supertree and medium-level approaches. Here, we present a simulation study to
compare different methods from each of these three approaches.\r\n\r\nResults:
We observe that superalignment methods usually outperform the other approaches
over a wide range of parameters including sparse data and gene-specific evolutionary
parameters. In the presence of high incongruency among gene trees, however, other
combination methods show better performance than the superalignment approach.
Surprisingly, some supertree and medium-level methods exhibit, on average, worse
results than a single gene phylogeny with complete taxon information.\r\n\r\nConclusions:
For some methods, using the reconstructed gene tree as an estimation of the species
tree is superior to the combination of incomplete information. Superalignment
usually performs best since it is less susceptible to stochastic error. Supertree
methods can outperform superalignment in the presence of gene-tree conflict."

text: 'Biological traits result in part from interactions between different genetic
loci. This can lead to sign epistasis, in which a beneficial adaptation involves
a combination of individually deleterious or neutral mutations; in this case,
a population must cross a “fitness valley” to adapt. Recombination can assist
this process by combining mutations from different individuals or retard it by
breaking up the adaptive combination. Here, we analyze the simplest fitness valley,
in which an adaptation requires one mutation at each of two loci to provide a
fitness benefit. We present a theoretical analysis of the effect of recombination
on the valley-crossing process across the full spectrum of possible parameter
regimes. We find that low recombination rates can speed up valley crossing relative
to the asexual case, while higher recombination rates slow down valley crossing,
with the transition between the two regimes occurring when the recombination rate
between the loci is approximately equal to the selective advantage provided by
the adaptation. In large populations, if the recombination rate is high and selection
against single mutants is substantial, the time to cross the valley grows exponentially
with population size, effectively meaning that the population cannot acquire the
adaptation. Recombination at the optimal (low) rate can reduce the valley-crossing
time by up to several orders of magnitude relative to that in an asexual population. '

text: We investigated temporal changes in hybridization and introgression between
native red deer (Cervus elaphus) and invasive Japanese sika (Cervus nippon) on
the Kintyre Peninsula, Scotland, over 15 years, through analysis of 1513 samples
of deer at 20 microsatellite loci and a mtDNA marker. We found no evidence that
either the proportion of recent hybrids, or the levels of introgression had changed
over the study period. Nevertheless, in one population where the two species have
been in contact since ∼1970, 44% of individuals sampled during the study were
hybrids. This suggests that hybridization between these species can proceed fairly
rapidly. By analysing the number of alleles that have introgressed from polymorphic
red deer into the genetically homogenous sika population, we reconstructed the
haplotypes of red deer alleles introduced by backcrossing. Five separate hybridization
events could account for all the recently hybridized sika-like individuals found
across a large section of the Peninsula. Although we demonstrate that low rates
of F1 hybridization can lead to substantial introgression, the progress of hybridization
and introgression appears to be unpredictable over the short timescales.

text: Long-term depression (LTD) is a form of synaptic plasticity that may contribute
to information storage in the central nervous system. Here we report that LTD
can be elicited in layer 5 pyramidal neurons of the rat prefrontal cortex by pairing
low frequency stimulation with a modest postsynaptic depolarization. The induction
of LTD required the activation of both metabotropic glutamate receptors of the
mGlu1 subtype and voltage-sensitive Ca(2+) channels (VSCCs) of the T/R, P/Q and
N types, leading to the stimulation of intracellular inositol trisphosphate (IP3)
receptors by IP3 and Ca(2+). The subsequent release of Ca(2+) from intracellular
stores activated the protein phosphatase cascade involving calcineurin and protein
phosphatase 1. The activation of purinergic P2Y(1) receptors blocked LTD. This
effect was prevented by P2Y(1) receptor antagonists and was absent in mice lacking
P2Y(1) but not P2Y(2) receptors. We also found that activation of P2Y(1) receptors
inhibits Ca(2+) transients via VSCCs in the apical dendrites and spines of pyramidal
neurons. In addition, we show that the release of ATP under hypoxia is able to
inhibit LTD by acting on postsynaptic P2Y(1) receptors. In conclusion, these data
suggest that the reduction of Ca(2+) influx via VSCCs caused by the activation
of P2Y(1) receptors by ATP is the possible mechanism for the inhibition of LTD
in prefrontal cortex.

text: The induction of a signaling pathway is characterized by transient complex
formation and mutual posttranslational modification of proteins. To faithfully
capture this combinatorial process in a math- ematical model is an important challenge
in systems biology. Exploiting the limited context on which most binding and modification
events are conditioned, attempts have been made to reduce the com- binatorial
complexity by quotienting the reachable set of molecular species, into species
aggregates while preserving the deterministic semantics of the thermodynamic limit.
Recently we proposed a quotienting that also preserves the stochastic semantics
and that is complete in the sense that the semantics of individual species can
be recovered from the aggregate semantics. In this paper we prove that this quotienting
yields a sufficient condition for weak lumpability and that it gives rise to a
backward Markov bisimulation between the original and aggregated transition system.
We illustrate the framework on a case study of the EGF/insulin receptor crosstalk.

text: If distinct biological species are to coexist in sympatry, they must be reproductively
isolated and must exploit different limiting resources. A two-niche Levene model
is analysed, in which habitat preference and survival depend on underlying additive
traits. The population genetics of preference and viability are equivalent. However,
there is a linear trade-off between the chances of settling in either niche, whereas
viabilities may be constrained arbitrarily. With a convex trade-off, a sexual
population evolves a single generalist genotype, whereas with a concave trade-off,
disruptive selection favours maximal variance. A pure habitat preference evolves
to global linkage equilibrium if mating occurs in a single pool, but remarkably,
evolves to pairwise linkage equilibrium within niches if mating is within those
niches--independent of the genetics. With a concave trade-off, the population
shifts sharply between a unimodal distribution with high gene flow and a bimodal
distribution with strong isolation, as the underlying genetic variance increases.
However, these alternative states are only simultaneously stable for a narrow
parameter range. A sharp threshold is only seen if survival in the 'wrong' niche
is low; otherwise, strong isolation is impossible. Gene flow from divergent demes
makes speciation much easier in parapatry than in sympatry.

text: 1. Hybridisation with an invasive species has the potential to alter the phenotype
and hence the ecology of a native counterpart. 2. Here data from populations of
native red deer Cervus elaphus and invasive sika deer Cervus nippon in Scotland
is used to assess the extent to which hybridisation between them is causing phenotypic
change. This is done by regression of phenotypic traits against genetic hybrid
scores. 3. Hybridisation is causing increases in the body weight of sika-like
deer and decreases in the body weight of red-like females. Hybridisation is causing
increases in jaw length and increases in incisor arcade breadth in sika-like females.
Hybridisation is also causing decreases in incisor arcade breadth in red-like
females. 4. There is currently no evidence that hybridisation is causing changes
in the kidney fat weight or pregnancy rates of either population. 5. Increased
phenotypic similarity between the two species is likely to lead to further hybridisation.
The ecological consequences of this are difficult to predict.

text: 'The prevalence of recombination in eukaryotes poses one of the most puzzling
questions in biology. The most compelling general explanation is that recombination
facilitates selection by breaking down the negative associations generated by
random drift (i.e. Hill-Robertson interference, HRI). I classify the effects of
HRI owing to: deleterious mutation, balancing selection and selective sweeps on:
neutral diversity, rates of adaptation and the mutation load. These effects are
mediated primarily by the density of deleterious mutations and of selective sweeps.
Sequence polymorphism and divergence suggest that these rates may be high enough
to cause significant interference even in genomic regions of high recombination.
However, neither seems able to generate enough variance in fitness to select strongly
for high rates of recombination. It is plausible that spatial and temporal fluctuations
in selection generate much more fitness variance, and hence selection for recombination,
than can be explained by uniformly deleterious mutations or species-wide selective
sweeps.'

text: 'Under the classical view, selection depends more or less directly on mutation:
standing genetic variance is maintained by a balance between selection and mutation,
and adaptation is fuelled by new favourable mutations. Recombination is favoured
if it breaks negative associations among selected alleles, which interfere with
adaptation. Such associations may be generated by negative epistasis, or by random
drift (leading to the Hill-Robertson effect). Both deterministic and stochastic
explanations depend primarily on the genomic mutation rate, U. This may be large
enough to explain high recombination rates in some organisms, but seems unlikely
to be so in general. Random drift is a more general source of negative linkage
disequilibria, and can cause selection for recombination even in large populations,
through the chance loss of new favourable mutations. The rate of species-wide
substitutions is much too low to drive this mechanism, but local fluctuations
in selection, combined with gene flow, may suffice. These arguments are illustrated
by comparing the interaction between good and bad mutations at unlinked loci under
the infinitesimal model.'

result is that species hybrids may be inferior to their parents, for example,
being less fertile [1]. The other is that F1 hybrids may display superior performance
(heterosis), for example with increased vigour [2]. Although various hypotheses
have been proposed to account for these two aspects of hybridisation, their biological
basis is still poorly understood [3]. To gain further insights into this issue,
we analysed the role that variation in gene expression may play. We took a conserved
trait, flower asymmetry in Antirrhinum, and determined the extent to which the
underlying regulatory genes varied in expression among closely related species.
We show that expression of both genes analysed, CYC and RAD, varies significantly
between species because of cis-acting differences. By making a quantitative genotype-phenotype
map, using a range of mutant alleles, we demonstrate that the species lie on a
plateau in gene expression-morphology space, so that the variation has no detectable
phenotypic effect. However, phenotypic differences can be revealed by shifting
genotypes off the plateau through genetic crosses. Our results can be readily
explained if genomes are free to evolve within an effectively neutral zone in
gene expression space. The consequences of this drift will be negligible for individual
loci, but when multiple loci across the genome are considered, we show that the
variation may have significant effects on phenotype and fitness, causing a significant
drift load. By considering these consequences for various gene-expression-fitness
landscapes, we conclude that F1 hybrids might be expected to show increased performance
with regard to conserved traits, such as basic physiology, but reduced performance
with regard to others. Thus, our study provides a new way of explaining how various
aspects of hybrid performance may arise through natural variation in gene activity.

text: In cortex surface segmentation, the extracted surface is required to have
a particular topology, namely, a two-sphere. We present a new method for removing
topology noise of a curve or surface within the level set framework, and thus
produce a cortical surface with correct topology. We define a new energy term
which quantifies topology noise. We then show how to minimize this term by computing
its functional derivative with respect to the level set function. This method
differs from existing methods in that it is inherently continuous and not digital;
and in the way that our energy directly relates to the topology of the underlying
curve or surface, versus existing knot-based measures which are related in a more
indirect fashion. The proposed flow is validated empirically.

text: MICROSATELIGHT is a Perl/Tk pipeline with a graphical user interface that
facilitates several tasks when scoring microsatellites. It implements new subroutines
in R and PERL and takes advantage of features provided by previously developed
freeware. MICROSATELIGHT takes raw genotype data and automates the peak identification
through PeakScanner. The PeakSelect subroutine assigns peaks to different microsatellite
markers according to their multiplex group, fluorochrome type, and size range.
After peak selection, binning of alleles can be carried out 1) automatically through
AlleloBin or 2) by manual bin definition through Binator. In both cases, several
features for quality checking and further binning improvement are provided. The
genotype table can then be converted into input files for several population genetics
programs through CREATE. Finally, Hardy–Weinberg equilibrium tests and confidence
intervals for null allele frequency can be obtained through GENEPOP. MICROSATELIGHT
is the only freely available public-domain software that facilitates full multiplex
microsatellite scoring, from electropherogram files to user-defined text files
to be used with population genetics software. MICROSATELIGHT has been created
for the Windows XP operating system and has been successfully tested under Windows
7. It is available at http://sourceforge.net/projects/microsatelight/.

text: Most fisheries involving spiny lobsters of the genus Palinurus have been over
exploited during the last decades, so there is a raising concern about management
decisions for these valuable resources. A total of 13 microsatellite DNA loci
recently developed in Palinurus elephas were assayed in order to assess genetic diversity levels in every known species of the genus. Microsatellite markers gave
amplifications and showed polymorphism in all species, with gene diversity values varying from 0.65060.077 SD (Palinurus
barbarae) to 0.79260.051 SD (Palinurus elephas). Most importantly, when depth
distribution was taken into account, shallower waters pecies consistently showed
larger historical effective population sizes than their deeper-water counterparts. This
could explain why deeper-water species are more sensitive to overfishing, and
would indicate that overexploitation may have a larger impact on their long-term
genetic diversity.

text: Four rare palinurid phyllosoma larvae, one mid-stage and three final stage,
were found among the unclassified collections in the Crustacea Section, Natural
History Museum, London. Detailed morphological analysis of the larvae indicated
that they belong to several Palinustus species given the presence of incipient
blunt-horns, length of antennula, length ratio of segments of antennular peduncle,
distribution of pereiopod spines, and shape of uropods and telson. Moreover, the
size of the final-stage larvae agrees with that expected given the size of the
recently described puerulus stage of Palinustus mossambicus. This constitutes
the first description of a complete phyllosoma assigned to Palinustus species.
The phyllosoma described in the present study include the largest Palinuridae
larva ever found.

text: DNA samples were extracted from ethanol and formalin-fixed decapod crustacean
tissue using a new method based on Tetramethylsilane (TMS)-Chelex. It is shown
that neither an indigestible matrix of cross-linked protein nor soluble PCR inhibitors
impede PCR success when dealing with formalin-fixed material. Instead, amplification
success from formalin-fixed tissue appears to depend on the presence of unmodified
DNA in the extracted sample. A staining method that facilitates the targeting
of samples with a high content of unmodified DNA is provided.

text: Cell sorting is a widespread phenomenon pivotal to the early development of
multicellular organisms. In vitro cell sorting studies have been instrumental
in revealing the cellular properties driving this process. However, these studies
have as yet been limited to two-dimensional analysis of three-dimensional cell
sorting events. Here we describe a method to record the sorting of primary zebrafish
ectoderm and mesoderm germ layer progenitor cells in three dimensions over time,
and quantitatively analyze their sorting behavior using an order parameter related
to heterotypic interface length. We investigate the cell population size dependence
of sorted aggregates and find that the germ layer progenitor cells engulfed in
the final configuration display a relationship between total interfacial length
and system size according to a simple geometrical argument, subject to a finite-size
effect.

text: 'The development of multicellular organisms is dependent on the tight coordination
between tissue growth and morphogenesis. The stereotypical orientation of cell
divisions has been proposed to be a fundamental mechanism by which proliferating
and growing tissues take shape. However, the actual contribution of stereotypical
division orientation (SDO) to tissue morphogenesis is unclear. In zebrafish, cell
divisions with stereotypical orientation have been implicated in both body-axis
elongation and neural rod formation [1, 2], although there is little direct evidence
for a critical function of SDO in either of these processes. Here we show that
SDO is required for formation of the neural rod midline during neurulation but
dispensable for elongation of the body axis during gastrulation. Our data indicate
that SDO during both gastrulation and neurulation is dependent on the noncanonical
Wnt receptor Frizzled 7 (Fz7) and that interfering with cell division orientation
leads to severe defects in neural rod midline formation but not body-axis elongation.
These findings suggest a novel function for Fz7-controlled cell division orientation
in neural rod midline formation during neurulation. '

text: Cell shape and motility are primarily controlled by cellular mechanics. The
attachment of the plasma membrane to the underlying actomyosin cortex has been
proposed to be important for cellular processes involving membrane deformation.
However, little is known about the actual function of membrane-to-cortex attachment
(MCA) in cell protrusion formation and migration, in particular in the context
of the developing embryo. Here, we use a multidisciplinary approach to study MCA
in zebrafish mesoderm and endoderm (mesendoderm) germ layer progenitor cells,
which migrate using a combination of different protrusion types, namely, lamellipodia,
filopodia, and blebs, during zebrafish gastrulation. By interfering with the activity
of molecules linking the cortex to the membrane and measuring resulting changes
in MCA by atomic force microscopy, we show that reducing MCA in mesendoderm progenitors
increases the proportion of cellular blebs and reduces the directionality of cell
migration. We propose that MCA is a key parameter controlling the relative proportions
of different cell protrusion types in mesendoderm progenitors, and thus is key
in controlling directed migration during gastrulation.
