text: "We present fully dynamic algorithms for maintaining the biconnected components
in general and plane graphs.\r\n\r\nA fully dynamic algorithm maintains a graph
during a sequence of insertions and deletions of edges or isolated vertices. Let
m be the number of edges and n be the number of vertices in a graph. The time
per operation of the best deterministic algorithms is \U0001D442(\U0001D45B√)
in general graphs and O(log n) in plane graphs for fully dynamic connectivity
and O(min m2/3 ,n}) in general graphs and \U0001D442(\U0001D45B√) in plane graphs
for fully dynamic biconnectivity. We improve the later running times to \U0001D442(\U0001D45Alog\U0001D45B‾‾‾‾‾‾‾√)
in general graphs and O(log 2n ) in plane graphs. Our algorithm for general graphscan
also find the biconnected components of all vertices in time O(n)."

text: In the theoretical description of recent experiments with dilute Bose gases
confined in external potentials the Gross-Pitaevskii equation plays an important
role. Its status as an approximation for the quantum mechanical many-body ground
state problem has recently been rigorously clarified. A summary of this work is
presented here.

text: We study the energy levels of a single particle in a homogeneous magnetic
field and in an axially symmetric external potential. For potentials that are
superharmonic off the central axis, we find a general 'pseudoconcave' ordering
of the ground state energies of the Hamiltonian restricted to the sectors with
fixed angular momentum. The physical applications include atoms and ions in strong
magnetic fields. There the energies are monotone increasing and concave in angular
momentum. In the case of a periodic chain of atoms, the pseudoconcavity extends
to the entire lowest band of Bloch functions.

text: For an absolutely continuous probability measure μ on Rd and a nonnegative
integer k, let sk(μ, 0) denote the probability that the convex hull of k+d+1 random
points which are i.i.d. according to μ contains the origin 0. For d and k given,
we determine a tight upper bound on sk(μ, 0), and we characterize the measures
in Rd which attain this bound. This result can be considered a continuous analogue
of the Upper Bound Theorem for the maximal number of faces of convex polytopes
with a given number of vertices. For our proof we introduce so-called h-functions,
continuous counterparts of h-vectors for simplicial convex polytopes.

text: 'This chapter focuses on metabotropic glutamate receptors (mGluRs). These
receptors are linked to several intracellular signal transduction mechanisms via
G-protein and are implicated in diverse functions of the mammalian central nervous
system (CNS). These functions include mediation of slow excitatory and inhibitory
responses; regulation of calcium channels, potassium channels, and non-selective
cation channels; inhibition and facilitation of transmitter release; induction
of long-term potentiation and long-term depression; and regulation of neuronal
development. Functional diversity of the metabotropic glutamate receptor is reflected
in molecular diversity of receptor subtypes. The sites of action of mGluRs are
widely found throughout different membrane compartments of neuronal and glial
cells. The chapter reviews the differential subcellular localization of metabotropic
glutamate receptors in relation to transmitter release sites. Patterns of subcellular
localization of mGluRs are different among three subgroups: group I and III mGluRs
are mainly localized to somatodendritic and axonal domains of neurons, respectively,
while group II mGluRs are extensively localized to both domains as well as to
glial cell processes.'

text: "There are many types of cerebellar ataxia, including ataxia due to congenital
or metabolic disorders and a paraneoplastic form in patients with gynecologic
cancer, breast cancer, lung cancer, or Hodgkin's disease.1 This paraneoplastic
syndrome is the only type of cerebellar ataxia associated with autoantibodies
against neuronal antigens. Often, the neuronal antigens are aberrantly expressed
by the tumor cells.2-4 The antineuronal autoantibodies are believed to cause cerebellar
ataxia, but this is unproved.5,6 In Hodgkin's disease, the lymphoma precedes the
ataxia by months to years in 80 percent of patients, and ataxia often occurs during
a prolonged complete remission.4 Among patients with this type of ataxia, 30 percent
have anti–Purkinje-cell antibodies, some of which have the features of the neuronal
antibody anti-Tr.4,7\r\n\r\nWe identified a new autoantibody in two patients with
severe cerebellar ataxia that developed while they were in remission from Hodgkin's
disease. The antibody reacts specifically with the metabotropic glutamate receptor
mGluR1 in mouse brain. Metabotropic glutamate receptors belong to a large family
of cell-surface receptors that transmit signals into the cell by coupling to guanine
nucleotide-binding proteins (G proteins) in the cytoplasm. Purified IgG from the
serum of both patients blocked the glutamate-stimulated formation of inositol
phosphates in Chinese-hamster-ovary (CHO) cells that expressed mGluR1α, and the
injection of IgG from serum or cerebrospinal fluid into the cerebellar subarachnoid
space of mice caused severe, reversible ataxia. These results indicate that antineuronal
autoantibodies can cause disease of the central nervous system by blocking neuronal
receptors."

text: 'The synaptic relationship between substance P (SP) and its receptor, i.e.,
neurokinin-1 receptor (NK1R), was examined in the striatum of the rat by confocal
laser-scanning microscopy and electron microscopy. For confocal laser-scanning
microscopy, triple-immunofluorescence histochemistry was performed to label NK1R,
SP, and vesicular acetylcholine transporter (a specific marker for cholinergic
neurons). In electron microscopic double- immunolabeling study, immunoreactivity
for NK1R was detected with the silver- intensified gold method, while immunoreactivity
for SP was detected with peroxidase immunohistochemistry. Simultaneous immunolabeling
of NK1R and SP revealed significant mismatch at the synaptic level: although some
SP- immunopositive axon terminals were in synaptic contact with NK1R- immunopositive
sites of plasma membrane, NK1R-immunoreactivity was observed at both synaptic
and non-synaptic sites of plasma membrane. Thus, SP released from the sites remote
from NK1Rs might diffuse in the extracellular fluid to act, as a paracrine neurotransmitter,
on NK1Rs distant from its releasing site. SP neurotransmission in the striatum
might occur not only synaptically but also extrasynaptically. The SP-NK1R system
might constitute an association system within the striatum.'

text: 'The synaptic relationship between substance P (SP) and its receptor, i.e.
neurokinin-1 receptor (NK1R), was examined in the superficial laminae of the caudal
subnucleus of the spinal trigeminal nucleus (medullary dorsal horn; MDH) of the
rat. For confocal laser-scanning microscopy, double-immunofluorescence histochemistry
for NK1 and SP was performed. In electron microscopic double-immunolabeling study,
immunoreactivity for NK1R was detected with the silver-intensified gold method,
while immunoreactivity for SP was detected with peroxidase immunohistochemistry.
SP-immunoreactive axon terminals were observed to be in synaptic (mostly asymmetric)

Although some SP-immunoreactive axon terminals were in synaptic contact with NK1R-immunoreactive
sites of plasma membranes, NK1R-immunoreactivity was observed at both synaptic

might not only act on NK1Rs facing the SP-containing axon terminals, but also
diffuse in the extracellular fluid for distances larger than the synaptic cleft
to act on NK1Rs at some distances from the synaptic sites. '

text: Targeted deletion of metabotropic glutamate receptor-subtype 1 (mGluR1) gene
can cause defects in development and function in the cerebellum. We introduced
the mGluR1α transgene into mGluR1-null mutant [mGluR1 (-/-)] mice with a Purkinje
cell (PC)-specific promoter. mGluR1-rescue mice showed normal cerebellar long-term
depression and regression of multiple climbing fiber innervation, events significantly
impaired in mGluR1 (-/-) mice. The impaired motor coordination was rescued by
this transgene, in a dose-dependent manner. We propose that mGluR1 in PCs is a
key molecule for normal synapse formation, synaptic plasticity, and motor control
in the cerebellum.

text: Although presynaptic localization of mGluR7 is well established, the mechanism
by which the receptor may control Ca2+ channels in neurons is still unknown. We
show here that cultured cerebellar granule cells express native metabotropic glutamate
receptor type 7 (mGluR7) in neuritic processes, whereas transfected mGluR7 was
also expressed in cell bodies. This allowed us to study the effect of the transfected
receptor on somatic Ca2+ channels. In transfected neurons, mGuR7 selectively inhibited
P/Q-type Ca2+ channels. The effect was mimicked by GTPγS and blocked by pertussis
toxin (PTX) or a selective antibody raised against the G-protein αo subunit, indicating
the involvement of a G(o)-like protein. The mGuR7 effect did not display the characteristics
of a direct interaction between G-protein βγ subunits and the α1A Ca2+ channel
subunit, but was abolished by quenching βγ subunits with specific intracellular
peptides. Intracellular dialysis of G-protein βγ subunits did not mimic the action
of mGluR7, suggesting that both G-protein βγ and αo subunits were required to
mediate the effect. Inhibition of phospholipase C (PLC) blocked the inhibitory
action of mGluR7, suggesting that a coincident activation of PLC by the G-protein
βγ with αo subunits was required. The Ca2+ chelator BAPTA, as well as inhibition
of either the inositol trisphosphate (IP3) receptor or protein kinase C (PKC)
abolished the mGluR7 effect. Moreover, activation of native mGluR7 induced a PTX-dependent
IP3 formation. These results indicated that IP3-mediated intracellular Ca2+ release
was required for PKC-dependent inhibition of the Ca2+ channels. Possible control
of synaptic transmission by the present mechanisms is discussed.

text: Aggregation of neurotransmitter receptors at pre- and postsynaptic structures
is crucial for efficient neuronal communication. In contrast to the wealth of
information about postsynaptic specializations, little is known about the molecular
organization of presynaptic membrane proteins. We show here that the metabotropic
glutamate receptor mGluR7a, which localizes specifically to presynaptic active
zones, interacts in vitro and in vivo with PICK1. Coexpression in heterologous
systems induces coclustering dependent upon the extreme C terminus of mGluR7a
and the PDZ domain of PICK1. mGluR7a and PICK1 localize to excitatory synapses
in hippocampal neurons. Furthermore, whereas transfected mGluR7a clusters at presynaptic
sites, mGluR7aΔ3 lacking the PICK1 binding site targets to axons but does not
cluster. These results suggest that PICK1 is a component of the presynaptic machinery
involved in mGlUR7a aggregation and in modulation of glutamate neurotransmission.

text: In this paper we describe an intrinsically geometric way of producing magnetic
fields on §3 and $\R^3$ for which the corresponding Dirac operators have a non-trivial
kernel. In many cases we are able to compute the dimension of the kernel. In particular
we can give examples where the kernel has any given dimension. This generalizes
the examples of Loss and Yau (Commun. Math. Phys. 104 (1986) 283-290).

We show that in the weak coupling limit the Wigner distribution of the wave function
converges to a solution of a linear Boltzmann equation globally in time. The Boltzmann
collision kernel is given by the Born approximation of the quantum differential
scattering cross section.

text: 'We consider a quantum particle moving in a harmonic exterior potential and
linearly coupled to a heat bath of quantum oscillators. Caldeira and Leggett derived
the Fokker Planck equation with friction for the Wigner distribution of the particle
in the large-temperature limit: however, their (nonrigorous) derivation was not
free of criticism, especially since the limiting equation is not of Lindblad form.
In this paper we recover the correct form of their result in a rigorous way. We
also point out that the source of the diffusion is physically restrictive under
this scaling. We investigate the model at a fixed temperature and in the large-time
limit, where the origin of the diffusion is a cumulative effect of many resonant
collisions. We obtain a heat equation with a friction term for the radial process
in phase space and we prove the Einstein relation in this case.'

text: The prohormone convertases (PCs) are an evolutionarily ancient group of proteases
required for the maturation of neuropeptide and peptide hormone precursors. In
Drosophila melanogaster, the homolog of prohormone convertase 2, dPC2 (amontillado),
is required for normal hatching behavior, and immunoblotting data indicate that
flies express 80- and 75-kDa forms of this protein. Because mouse PC2 (mPC2) requires
7B2, a helper protein for productive maturation, we searched the fly data base
for the 7B2 signature motif PPNPCP and identified an expressed sequence tag clone
encoding the entire open reading frame for this protein. dPC2 and d7B2 cDNAs were
subcloned into expression vectors for transfection into HEK-293 cells; mPC2 and
rat 7B2 were used as controls. Although active mPC2 was detected in medium in
the presence of either d7B2 or r7B2, dPC2 showed no proteolytic activity upon
coexpression of either d7B2 or r7B2. Labeling experiments showed that dPC2 was
synthesized but not secreted from HEK-293 cells. However, when dPC2 and either
d7B2 or r7B2 were coexpressed in Drosophila S2 cells, abundant immunoreactive
dPC2 was secreted into the medium, coincident with the appearance of PC2 activity.
Expression and secretion of dPC2 enzyme activity thus appears to require insect
cell-specific posttranslational processing events. The significant differences
in the cell biology of the insect and mammalian enzymes, with 7B2 absolutely required
for secretion of dPC2 and zymogen conversion occurring intracellularly in the
case of dPC2 but not mPC2, support the idea that the Drosophila enzyme has specific
requirements for maturation and secretion that can be met only in insect cells.

text: We have examined factors that determine the strength and dynamics of GABAergic
synapses between interneurons [dentate gyrus basket cells (BCs)] and principal
neurons [dentate gyrus granule cells (GCs)] using paired recordings in rat hippocampal
slices at 34°C. Unitary IPSCs recorded from BC–GC pairs in high intracellular
Cl− concentration showed a fast rise and a biexponential decay, with mean time
constants of 2 and 9 msec. The mean quantal conductance change, determined directly
at reduced extracellular Ca2+/Mg2+concentration ratios, was 1.7 nS. Quantal release
at the BC–GC synapse occurred with short delay and was highly synchronized. Analysis
of IPSC peak amplitudes and numbers of failures by multiple probability compound
binomial analysis indicated that synaptic transmission at the BC–GC synapse involves
three to seven release sites, each of which releases transmitter with high probability
(∼0.5 in 2 mMCa2+/1 mM Mg2+). Unitary BC–GC IPSCs showed paired-pulse depression
(PPD); maximal depression, measured for 10 msec intervals, was 37%, and recovery
from depression occurred with a time constant of 2 sec. Paired-pulse depression
was mainly presynaptic in origin but appeared to be independent of previous release.
Synaptic transmission at the BC–GC synapse showed frequency-dependent depression,
with half-maximal decrease at 5 Hz after a series of 1000 presynaptic action potentials.
The relative stability of transmission at the BC–GC synapse is consistent with
a model in which an activity-dependent gating mechanism reduces release probability
and thereby prevents depletion of the releasable pool of synaptic vesicles. Thus
several mechanisms converge on the generation of powerful and sustained transmission
at interneuron–principal neuron synapses in hippocampal circuits.
