text: Since the first experimental realization of Bose-Einstein condensation in
cold atomic gases in 1995 there has been a surge of activity in this field. Ingenious
experiments have allowed us to probe matter close to zero temperature and reveal
some of the fascinating effects quantum mechanics has bestowed on nature. It is
a challenge for mathematical physicists to understand these various phenomena
from first principles, that is, starting from the underlying many-body Schrödinger
equation. Recent progress in this direction concerns mainly equilibrium properties
of dilute, cold quantum gases. We shall explain some of the results in this article,
and describe the mathematics involved in understanding these phenomena. Topics
include the ground state energy and the free energy at positive temperature, the
effect of interparticle interaction on the critical temperature for Bose-Einstein
condensation, as well as the occurrence of superfluidity and quantized vortices
in rapidly rotating gases.

text: The binding of polarons, or its absence, is an old and subtle topic. Here
we prove two things rigorously. First, the transition from many-body collapse
to the existence of a thermodynamic limit for N polarons occurs precisely at U=2α,
where U is the electronic Coulomb repulsion and α is the polaron coupling constant.
Second, if U is large enough, there is no multipolaron binding of any kind. Considering
the known fact that there is binding for some U>2α, these conclusions are not
obvious and their proof has been an open problem for some time.

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: In a new study published in this issue of Developmental Cell, Krouk et al.
reveal a surprising mechanism by which plant root systems adapt their architecture
for soil exploitation. The dual transporter NRT1.1 uses both nitrate and the plant
hormone auxin as substrates, enabling soil nitrate availability to regulate auxin-driven
lateral root development.

text: Epilepsy is a devastating and poorly understood disease. Mutations in a secreted
neuronal protein, leucine-rich glioma inactivated 1 (LGI1), were reported in patients
with an inherited form of human epilepsy, autosomal dominant partial epilepsy
with auditory features (ADPEAF). Here, we report an essential role of LGI1 as
an antiepileptogenic ligand. We find that loss of LGI1 in mice (LGI1-/-) causes
lethal epilepsy, which is specifically rescued by the neuronal expression of LGI1
transgene, but not LGI3. Moreover, heterozygous mice for the LGI1 mutation (LGI1+/-)
show lowered seizure thresholds. Extracellularly secreted LGI1 links two epilepsy-related
receptors, ADAM22 and ADAM23, in the brain and organizes a transsynaptic protein
complex that includes presynaptic potassium channels and postsynaptic AMPA receptor
scaffolds. A lack of LGI1 disrupts this synaptic protein connection and selectively
reduces AMPA receptor-mediated synaptic transmission in the hippocampus. Thus,
LGI1 may serve as a major determinant of brain excitation, and the LGI1 gene-targeted
mouse provides a good model for human epilepsy.

text: We present a method for immunolabeling of multiple species of membrane proteins
with high spatial resolution. It allows differentiation of equally sized very
small markers with different chemical compositions, which leads to high labeling
efficiency and reduces steric hindrance of closely spaced immunolabeled biomolecules.
Markers such as CdSe/ZnS semiconductor quantum dots and colloidal gold particles
are distinguished by differential contrast in high-angle annular detector dark-field
STEM mode or by EDX microanalysis of their elemental contents. This method was
tested by observation of labeled AMPA- and NMDA-type glutamate receptors on sodium-dodecyl-sulfate-digested
replica prepared from rat hippocampus. To improve particle visibility and detectability,
the replica films were made exclusively with carbon to avoid the high background
of conventional platinum/carbon replica. Extension of the method is suggested
by detection of 1.4 nm nanogold particles and its potential application in the
biological imaging research.

text: Cbln1, secreted from cerebellar granule cells, and the orphan glutamate receptor
52 (GluD2), expressed by Purkinje cells, are essential for synapse integrity between
these neurons in adult mice. Nevertheless, no endogenous binding partners for
these molecules have been identified. We found that Cblnl binds directly to the
N-terminal domain of GluD2. GluD2 expression by postsynaptic cells, combined with
exogenously applied Cbln1, was necessary and sufficient to induce new synapses
in vitro and in the adult cerebellum in vivo. Further, beads coated with recombinant
Cbln1 directly induced presynaptic differentiation and indirectly caused clustering
of postsynaptic molecules via GluD2. These results indicate that the Cbln1-GluD2
complex is a unique synapse organizer that acts bidirectionally on both pre- and
postsynaptic components.

text: Subepithelial fibroblasts of the intestinal villi, which form a contractile
cellular network beneath the epithelium, are in close contact with epithelial
cells, nerve varicosities, capillaries, smooth muscles and immune cells, and secrete
extracellular matrix molecules, growth factors and cytokines, etc. Cultured subepithelial
fibroblasts of the rat duodenal villi display various receptors such as endothelins,
ATP, substance-P and bradykinin, and release ATP in response to mechanical stimulation.
In this study, the presence of functional NK1 receptors (NK1R) was pharmacologically
confirmed in primary culture by Ca 2+ measurement, and the effects of substance-P
were measured in an acute preparation of epithelium-free duodenal villi from 2-
to 3-week-old rats using a two-photon laser microscope. Substance-P elicited an
increase in the intracellular Ca 2+ concentration and contraction of the subepithelial
fibroblasts in culture and the isolated villi. The localization of NK1R and substance-P
in the villi was examined by light and electron microscopic immunohistochemistry.
NK1R-like immunoreactivity was intensely localized on the plasma membrane of villous
subepithelial fibroblasts in 10-day- to 4-week-old rats and mice and was decreased
or absent in adulthood. The pericryptal fibroblasts of the small and large intestine
were NK1R immuno-negative. These villous subepithelial fibroblasts form synapse-like
structures with both substance-P-immunopositive and -immunonegative nerve varicosities.
Here, we propose that the mutual interaction between villous subepithelial fibroblasts
and afferent neurons via substance-P and ATP plays important roles in the maturation
of the structure and function of the small intestine.

text: T-type calcium channels play a pivotal role in regulating neural membrane
excitability in the nervous system. However, the precise subcellular distributions
of T-type channel subunits and their implication for membrane excitability are
not well understood. Here we investigated the subcellular distribution of the
α1G subunit of the calcium channel which is expressed highly in the mouse dorsal
lateral geniculate nucleus (dLGN). Light microscopic analysis demonstrated that
dLGN exhibits intense immunoperoxidase reactivity for the α1G subunit. Electron
microscopic observation showed that the labeling was present in both the relay
cells and interneurons and was found in the somatodendritic, but not axonal, domains
of these cells. Most of the immunogold particles for the α1G subunit were either
associated with the plasma membrane or the intracellular membranes. Reconstruction
analysis of serial electron microscopic images revealed that the intensity of
the intracellular labeling exhibited a gradient such that the labeling density
was higher in the proximal dendrite and progressively decreased towards the distal
dendrite. In contrast, the plasma membrane-associated particles were distributed
with a uniform density over the somatodendritic surface of dLGN cells. The labeling
density in the relay cell plasma membrane was about 3-fold higher than that of
the interneurons. These results provide ultrastructural evidence for cell-type-specific
expression levels and for uniform expression density of the α1G subunit over the
plasma membrane of dLGN cells.

text: 'The activity patterns of subthalamic nucleus (STN) neurons are intimately
linked to motor function and dysfunction and arise through the complex interaction
of intrinsic properties and inhibitory and excitatory synaptic inputs. In many
neurons, hyperpolarization-activated cyclic nucleotide-gated (HCN) channels play
key roles in intrinsic excitability and synaptic integration both under normal
conditions and in disease states. However, in STN neurons, which strongly express
HCN channels, their roles remain relatively obscure. To address this deficit,
complementary molecular and cellular electrophysiological, imaging, and computational
approaches were applied to the rat STN. Molecular profiling demonstrated that
individual STN neurons express mRNA encoding several HCN subunits, with HCN2 and
3 being the most abundant. Light and electron microscopic analysis showed that
HCN2 subunits are strongly expressed and distributed throughout the somatodendritic
plasma membrane. Voltage-, current-, and dynamic-clamp analysis, two-photon Ca
2+ imaging, and computational modeling revealed that HCN channels are activated
by GABA A receptor-mediated inputs and thus limit synaptic hyperpolarization and
deinactivation of low-voltage-activated Ca 2+ channels. Although HCN channels
also limited the temporal summation of EPSPs, generated through two-photon uncaging
of glutamate, this action was largely shunted by GABAergic inhibition that was
necessary for HCN channel activation. Together the data demonstrate that HCN channels
in STN neurons selectively counteract GABA A receptor-mediated inhibition arising
from the globus pallidus and thus promote single-spike activity rather than rebound
burst firing. '

text: Hippocampal CA1 pyramidal cells, which receive γ-aminobutyric acid (GABA)ergic
input from at least 18 types of presynaptic neuron, express 14 subunits of the
pentameric GABAA receptor. The relative contribution of any subunit to synaptic
and extrasynaptic receptors influences the dynamics of GABA and drug actions.
Synaptic receptors mediate phasic GABA-evoked conductance and extrasynaptic receptors
contribute to a tonic conductance. We used freeze-fracture replica-immunogold
labelling, a sensitive quantitative immunocytochemical method, to detect synaptic
and extrasynaptic pools of the alpha1, alpha2 and beta3 subunits. Antibodies to
the cytoplasmic loop of the subunits showed immunogold particles concentrated
on distinct clusters of intramembrane particles (IMPs) on the cytoplasmic face
of the plasma membrane on the somata, dendrites and axon initial segments, with
an abrupt decrease in labelling at the edge of the IMP cluster. Neuroligin-2,
a GABAergic synapse-specific adhesion molecule, co-labels all beta3 subunit-rich
IMP clusters, therefore we considered them synapses. Double-labelling for two
subunits showed that virtually all somatic synapses contain the alpha1, alpha2
and beta3 subunits. The extrasynaptic plasma membrane of the somata, dendrites
and dendritic spines showed low-density immunolabelling. Synaptic labelling densities
on somata for the alpha1, alpha2 and beta3 subunits were 78-132, 94 and 79 times
higher than on the extrasynaptic membranes, respectively. As GABAergic synapses
occupy 0.72% of the soma surface, the fraction of synaptic labelling was 33-48
(alpha1), 40 (alpha2) and 36 (beta3)% of the total somatic surface immunolabelling.
Assuming similar antibody access to all receptors, about 60% of these subunits
are in extrasynaptic receptors.

text: Neurons in the laterocapsular division of the central nucleus of the amygdala
(CeC), which is known as the "nociceptive amygdala," receive glutamatergic
inputs from the parabrachial nucleus (PB) and the basolateral nucleus of amygdala
(BLA), which convey nociceptive information from the dorsal horn of the spinal
cord and polymodal information from the thalamus and cortex, respectively. Here,
we examined the ultrastructural properties of PB- and BLA-CeC synapses identified
with EGFP-expressing lentivirus in rats. In addition, the density of synaptic
AMPA receptors (AMPARs) on CeC neurons was studied by using highly sensitive SDS-digested
freeze-fracture replica labeling (SDS-FRL). Afferents from the PB made asymmetrical
synapses mainly on dendritic shafts (88%), whereas those from the BLA were on
dendritic spines (81%). PB-CeC synapses in dendritic shafts were significantly
larger (median 0.072 μm 2) than BLA-CeC synapses in spines (median 0.058 μm 2;
P = 0.02). The dendritic shafts that made synapses with PB fibers were also significantly
larger than those that made synapses with BLA fibers, indicating that the PB fibers
make synapses on more proximal parts of dendrites than the BLA fibers. SDS-FRL
revealed that almost all excitatory postsynaptic sites have AMPARs in the CeC.
The density of AMPAR-specific gold particles in individual synapses was significantly
higher in spine synapses (median 510 particles/μm 2) than in shaft synapses (median
427 particles/μm 2; P = 0.01). These results suggest that distinct synaptic impacts
from PB- and BLA-CeC pathways contribute to the integration of nociceptive and
polymodal information in the CeC.

text: Morphogens are secreted signalling molecules that act in a graded manner to
control the pattern of cellular differentiation in developing tissues. An example
is Sonic hedgehog (Shh), which acts in several developing vertebrate tissues,
including the central nervous system, to provide positional information during
embryonic patterning. Here we address how Shh signalling assigns the positional
identities of distinct neuronal subtype progenitors throughout the ventral neural
tube. Assays of intracellular signal transduction and gene expression indicate
that the duration as well as level of signalling is critical for morphogen interpretation.
Progenitors of the ventral neuronal subtypes are established sequentially, with
progressively more ventral identities requiring correspondingly higher levels
and longer periods of Shh signalling. Moreover, cells remain sensitive to changes
in Shh signalling for an extended time, reverting to antecedent identities if
signalling levels fall below a threshold. Thus, the duration of signalling is
important not only for the assignment but also for the refinement and maintenance
of positional identity. Together the data suggest a dynamic model for ventral
neural tube patterning in which positional information corresponds to the time
integral of Shh signalling. This suggests an alternative to conventional models
of morphogen action that rely solely on the level of signalling.

text: The epitaxial growth of germanium on silicon leads to the self-assembly of
SiGe nanocrystals by a process that allows the size, composition and position
of the nanocrystals to be controlled. This level of control, combined with an
inherent compatibility with silicon technology, could prove useful in nanoelectronic
applications. Here, we report the confinement of holes in quantum-dot devices
made by directly contacting individual SiGe nanocrystals with aluminium electrodes,
and the production of hybrid superconductor- semiconductor devices, such as resonant
supercurrent transistors, when the quantum dot is strongly coupled to the electrodes.
Charge transport measurements on weakly coupled quantum dots reveal discrete energy
spectra, with the confined hole states displaying anisotropic gyromagnetic factors
and strong spin-orbit coupling with pronounced dependences on gate voltage and
magnetic field.
