A black-box combiner for collision resistant hash functions (CRHF) is a construction which given black-box access to two hash functions is collision resistant if at least one of the components is collision resistant. In this paper we prove a lower bound on the output length of black-box combiners for CRHFs. The bound we prove is basically tight as it is achieved by a recent construction of Canetti et al [Crypto'07]. The best previously known lower bounds only ruled out a very restricted class of combiners having a very strong security reduction: the reduction was required to output collisions for both underlying candidate hash-functions given a single collision for the combiner (Canetti et al [Crypto'07] building on Boneh and Boyen [Crypto'06] and Pietrzak [Eurocrypt'07]). Our proof uses a lemma similar to the elegant "reconstruction lemma" of Gennaro and Trevisan [FOCS'00], which states that any function which is not one-way is compressible (and thus uniformly random function must be one-way). In a similar vein we show that a function which is not collision resistant is compressible. We also borrow ideas from recent work by Haitner et al. [FOCS'07], who show that one can prove the reconstruction lemma even relative to some very powerful oracles (in our case this will be an exponential time collision-finding oracle). © 2008 Springer-Verlag Berlin Heidelberg.

text: 'We construct a stream-cipher S whose implementation is secure even if a bounded
amount of arbitrary (adversarially chosen) information on the internal state ofS
is leaked during computation. This captures all possible side-channel attacks
on S where the amount of information leaked in a given period is bounded, but
overall can be arbitrary large. The only other assumption we make on the implementation
of S is that only data that is accessed during computation leaks information.
The stream-cipher S generates its output in chunks K1, K2, . . . and arbitrary
but bounded information leakage is modeled by allowing the adversary to adaptively
chose a function fl : {0,1}* rarr {0, 1}lambda before Kl is computed, she then
gets fl(taul) where taul is the internal state ofS that is accessed during the
computation of Kg. One notion of security we prove for S is that Kg is indistinguishable
from random when given K1,..., K1-1,f1(tau1 ),..., fl-1(taul-1) and also the complete
internal state of S after Kg has been computed (i.e. S is forward-secure). The
construction is based on alternating extraction (used in the intrusion-resilient
secret-sharing scheme from FOCS''07). We move this concept to the computational
setting by proving a lemma that states that the output of any PRG has high HILLpseudoentropy
(i.e. is indistinguishable from some distribution with high min-entropy) even
if arbitrary information about the seed is leaked. The amount of leakage lambda
that we can tolerate in each step depends on the strength of the underlying PRG,
it is at least logarithmic, but can be as large as a constant fraction of the
internal state of S if the PRG is exponentially hard.'

text: 'The filamentous fungus Aspergillus fumigatus is responsible for a lethal
disease called Invasive Aspergillosis that affects immunocompromised patients.
This disease, like other human fungal diseases, is generally treated by compounds
targeting the primary fungal cell membrane sterol. Recently, glucan synthesis
inhibitors were added to the limited antifungal arsenal and encouraged the search
for novel targets in cell wall biosynthesis. Although galactomannan is a major
component of the A. fumigatus cell wall and extracellular matrix, the biosynthesis
and role of galactomannan are currently unknown. By a targeted gene deletion approach,
we demonstrate that UDP-galactopyranose mutase, a key enzyme of galactofuranose
metabolism, controls the biosynthesis of galactomannan and galactofuranose containing
glycoconjugates. The glfA deletion mutant generated in this study is devoid of
galactofuranose and displays attenuated virulence in a low-dose mouse model of
invasive aspergillosis that likely reflects the impaired growth of the mutant
at mammalian body temperature. Furthermore, the absence of galactofuranose results
in a thinner cell wall that correlates with an increased susceptibility to several
antifungal agents. The UDP-galactopyranose mutase thus appears to be an appealing
adjunct therapeutic target in combination with other drugs against A. fumigatus.
Its absence from mammalian cells indeed offers a considerable advantage to achieve
therapeutic selectivity. '

text: A complete mitochondrial (mt) genome sequence was reconstructed from a 38,000
year-old Neandertal individual with 8341 mtDNA sequences identified among 4.8
Gb of DNA generated from ∼0.3 g of bone. Analysis of the assembled sequence unequivocally
establishes that the Neandertal mtDNA falls outside the variation of extant human
mtDNAs, and allows an estimate of the divergence date between the two mtDNA lineages
of 660,000 ± 140,000 years. Of the 13 proteins encoded in the mtDNA, subunit 2
of cytochrome c oxidase of the mitochondrial electron transport chain has experienced
the largest number of amino acid substitutions in human ancestors since the separation
from Neandertals. There is evidence that purifying selection in the Neandertal
mtDNA was reduced compared with other primate lineages, suggesting that the effective
population size of Neandertals was small.

text: The nuclear envelope (NE) provides a selective barrier between the nuclear
interior and the cytoplasm and constitutes a central component of intracellular
architecture. During mitosis in metazoa, the NE breaks down leading to the complete
mixing of the nuclear content with the cytosol. Interestingly, many NE components
actively participate in mitotic progression. After chromosome segregation, the
NE is reassembled around decondensing chromatin and the nuclear compartment is
reestablished in the daughter cells. Here, we summarize recent progress in deciphering
the molecular mechanisms underlying NE dynamics during cell division.

text: Nuclear pore complexes are large aqueous channels that penetrate the nuclear
envelope, thereby connecting the nuclear interior with the cytoplasm. Until recently,
these macromolecular complexes were viewed as static structures, the only function
of which was to control the molecular trafficking between the two compartments.
It has now become evident that this simplistic scenario is inaccurate and that
nuclear pore complexes are highly dynamic multiprotein assemblies involved in
diverse cellular processes ranging from the organization of the cytoskeleton to
gene expression. In this review, we discuss the most recent developments in the
nuclear-pore-complex field, focusing on the assembly, disassembly, maintenance
and function of this macromolecular structure.

text: During mitosis in metazoans, segregated chromosomes become enclosed by the
nuclear envelope (NE), a double membrane that is continuous with the endoplasmic
reticulum (ER). Recent in vitro data suggest that NE formation occurs by chromatin-mediated
reorganization of the tubular ER; however, the basic principles of such a membrane-reshaping
process remain uncharacterized. Here, we present a quantitative analysis of nuclear
membrane assembly in mammalian cells using time-lapse microscopy. From the initial
recruitment of ER tubules to chromatin, the formation of a membrane-enclosed,
transport-competent nucleus occurs within ∼12 min. Overexpression of the ER tubule-forming
proteins reticulon 3, reticulon 4, and DP1 inhibits NE formation and nuclear expansion,
whereas their knockdown accelerates nuclear assembly. This suggests that the transition
from membrane tubules to sheets is rate-limiting for nuclear assembly. Our results
provide evidence that ER-shaping proteins are directly involved in the reconstruction
of the nuclear compartment and that morphological restructuring of the ER is the
principal mechanism of NE formation in vivo.

text: The nuclear envelope is a double-layered membrane that encloses the nuclear
genome and transcriptional machinery. In dividing cells of metazoa, the nucleus
completely disassembles during mitosis, creating the need to re-establish the
nuclear compartment at the end of each cell division. Given the crucial role of
the nuclear envelope in gene regulation and cellular organization, it is not surprising
that its biogenesis and organization have become active research areas. We will
review recent insights into nuclear membrane dynamics during the cell cycle.

text: The nuclear envelope (NE), a double membrane enclosing the nucleus of eukaryotic
cells, controls the flow of information between the nucleoplasm and the cytoplasm
and provides a scaffold for the organization of chromatin and the cytoskeleton.
In dividing metazoan cells, the NE breaks down at the onset of mitosis and then
reforms around segregated chromosomes to generate the daughter nuclei. Recent
data from intact cells and cell-free nuclear assembly systems suggest that the
endoplasmic reticulum (ER) is the source of membrane for NE assembly. At the end
of mitosis, ER membrane tubules are targeted to chromatin via tubule ends and
reorganized into flat nuclear membrane sheets by specific DNA-binding membrane
proteins. In contrast to previous models, which proposed vesicle fusion to be
the principal mechanism of NE formation, these new studies suggest that the nuclear
membrane forms by the chromatin-mediated reshaping of the ER.

text: We present a miniaturized pull-down method for the detection of protein-protein
interactions using standard affinity chromatography reagents. Binding events between
different proteins, which are color-coded with quantum dots (QDs), are visualized
on single affinity chromatography beads by fluorescence microscopy. The use of
QDs for single molecule detection allows the simultaneous analysis of multiple
protein-protein binding events and reduces the amount of time and material needed
to perform a pull-down experiment.

text: Mutation rate varies greatly between nucleotide sites of the human genome
and depends both on the global genomic location and the local sequence context
of a site. In particular, CpG context elevates the mutation rate by an order of
magnitude. Mutations also vary widely in their effect on the molecular function,
phenotype, and fitness. Independence of the probability of occurrence of a new
mutation's effect has been a fundamental premise in genetics. However, highly
mutable contexts may be preserved by negative selection at important sites but
destroyed by mutation at sites under no selection. Thus, there may be a positive
correlation between the rate of mutations at a nucleotide site and the magnitude
of their effect on fitness. We studied the impact of CpG context on the rate of
human-chimpanzee divergence and on intrahuman nucleotide diversity at non-synonymous
coding sites. We compared nucleotides that occupy identical positions within codons
of identical amino acids and only differ by being within versus outside CpG context.
Nucleotides within CpG context are under a stronger negative selection, as revealed
by their lower, proportionally to the mutation rate, rate of evolution and nucleotide
diversity. In particular, the probability of fixation of a non-synonymous transition
at a CpG site is two times lower than at a CpG site. Thus, sites with different
mutation rates are not necessarily selectively equivalent. This suggests that
the mutation rate may complement sequence conservation as a characteristic predictive
of functional importance of nucleotide sites.

text: The KIX domain of the transcription co-activator CBP is a three-helix bundle
protein that folds via rapid accumulation of an intermediate state, followed by
a slower folding phase. Recent NMR relaxation dispersion studies revealed the
presence of a low-populated (excited) state of KIX that exists in equilibrium
with the natively folded form under non-denaturing conditions, and likely represents
the equilibrium analog of the folding intermediate. Here, we combine amide hydrogen/deuterium
exchange measurements using rapid NMR data acquisition techniques with backbone
15N and 13C relaxation dispersion experiments to further investigate the equilibrium
folding of the KIX domain. Residual structure within the folding intermediate
is detected by both methods, and their combination enables reliable quantification
of the amount of persistent residual structure. Three well-defined folding subunits
are found, which display variable stability and correspond closely to the individual
helices in the native state. While two of the three helices (α2 and α3) are partially
formed in the folding intermediate (to ∼ 50% and ∼ 80%, respectively, at 20 °C),
the third helix is disordered. The observed helical content within the excited
state exceeds the helical propensities predicted for the corresponding peptide
regions, suggesting that the two helices are weakly mutually stabilized, while
methyl 13C relaxation dispersion data indicate that a defined packing arrangement
is unlikely. Temperature-dependent experiments reveal that the largest enthalpy
and entropy changes along the folding reaction occur during the final transition
from the intermediate to the native state. Our experimental data are consistent
with a folding mechanism where helices α2 and α3 form rapidly, although to different
extents, while helix α1 consolidates only as folding proceeds to complete the
native state-structure.

text: 'The copK gene is localized on the pMOL30 plasmid of Cupriavidus metallidurans
CH34 within the complex cop cluster of genes, for which 21 genes have been identified.
The expression of the corresponding periplasmic CopK protein is strongly upregulated
in the presence of copper, leading to a high periplasmic accumulation. The structure
and metal-binding properties of CopK were investigated by NMR and mass spectrometry.
The protein is dimeric in the apo state with a dissociation constant in the range
of 10- 5 M estimated from analytical ultracentrifugation. Mass spectrometry revealed
that CopK has two high-affinity Cu(I)-binding sites per monomer with different
Cu(I) affinities. Binding of Cu(II) was observed but appeared to be non-specific.
The solution structure of apo-CopK revealed an all-β fold formed of two β-sheets
in perpendicular orientation with an unstructured C-terminal tail. The dimer interface
is formed by the surface of the C-terminal β-sheet. Binding of the first Cu(I)-ion
induces a major structural modification involving dissociation of the dimeric
apo-protein. Backbone chemical shifts determined for the 1Cu(I)-bound form confirm
the conservation of the N-terminal β-sheet, while the last strand of the C-terminal
sheet appears in slow conformational exchange. We hypothesize that the partial
disruption of the C-terminal β-sheet is related to dimer dissociation. NH-exchange
data acquired on the apo-protein are consistent with a lower thermodynamic stability
of the C-terminal sheet. CopK contains seven methionine residues, five of which
appear highly conserved. Chemical shift data suggest implication of two or three
methionines (Met54, Met38, Met28) in the first Cu(I) site. Addition of a second
Cu(I) ion further increases protein plasticity. Comparison of the structural and
metal-binding properties of CopK with other periplasmic copper-binding proteins
reveals two conserved features within these functionally related proteins: the
all-β fold and the methionine-rich Cu(I)-binding site.'

text: The SOFAST-HMQC experiment [P. Schanda, B. Brutscher, Very fast two-dimensional
NMR spectroscopy for real-time investigation of dynamic events in proteins on
the time scale of seconds, J. Am. Chem. Soc. 127 (2005) 8014–8015] allows recording
two-dimensional correlation spectra of macromolecules such as proteins in only
a few seconds acquisition time. To achieve the highest possible sensitivity, SOFAST-HMQC
experiments are preferably performed on high-field NMR spectrometers equipped
with cryogenically cooled probes. The duty cycle of over 80% in fast-pulsing SOFAST-HMQC
experiments, however, may cause problems when using a cryogenic probe. Here we
introduce SE-IPAP-SOFAST-HMQC, a new pulse sequence that provides comparable sensitivity
to standard SOFAST-HMQC, while avoiding heteronuclear decoupling during 1H detection,
and thus significantly reducing the radiofrequency load of the probe during the
experiment. The experiment is also attractive for fast and sensitive measurement
of heteronuclear one-bond spin coupling constants.

text: The goal of this paper is to present to nonspecialists what is perhaps the
simplest possible geometrical picture explaining the mechanism of Arnold diffusion.
We choose to speak of a specific model—that of geometric rays in a periodic optical
medium. This model is equivalent to that of a particle in a periodic potential
in ${\mathbb R}^{n}$ with energy prescribed and to the geodesic flow in a Riemannian
metric on ${\mathbb R}^{n} $.

text: In this paper, using the ideas of Bessi and Mather, we present a simple mechanical
system exhibiting Arnold diffusion. This system of a particle in a small periodic
potential can be also interpreted as ray propagation in a periodic optical medium
with a near-constant index of refraction. Arnold diffusion in this context manifests
itself as an arbitrary finite change of direction for nearly constant index of
refraction.

text: Background. The arginine vasopressin V1a receptor (V1aR) modulates social
cognition and behavior in a wide variety of species. Variation in a repetitive
microsatellite element in the 5′ flanking region of the V1aR gene (AVPR1A) in
rodents has been associated with variation in brain V1aR expression and in social
behavior. In humans, the 5′ flanking region of AVPR1A contains a tandem duplication
of two ∼350 bp, microsatellite-containing elements located approximately 3.5 kb
upstream of the transcription start site. The first block, referred to as DupA,
contains a polymorphic (GT) 25microsatellite; the second block, DupB, has a complex
(CT) 4-(TT)-(CT)8-(GT)24polymorphic motif, known as RS3. Polymorphisms in RS3
have been associated with variation in sociobehavioral traits in humans, including
autism spectrum disorders. Thus, evolution of these regions may have contributed
to variation in social behavior in primates. We examined the structure of these
regions in six ape, six monkey, and one prosimian species. Results. Both tandem
repeat blocks are present upstream of the AVPR1A coding region in five of the
ape species we investigated, while monkeys have only one copy of this region.
As in humans, the microsatellites within DupA and DupB are polymorphic in many
primate species. Furthermore, both single (lacking DupB) and duplicated alleles
(containing both DupA and DupB) are present in chimpanzee (Pan troglodytes) populations
with allele frequencies of 0.795 and 0.205 for the single and duplicated alleles,
respectively, based on the analysis of 47 wild-caught individuals. Finally, a
phylogenetic reconstruction suggests two alternate evolutionary histories for
this locus. Conclusion. There is no obvious relationship between the presence
of the RS3 duplication and social organization in primates. However, polymorphisms
identified in some species may be useful in future genetic association studies.
In particular, the presence of both single and duplicated alleles in chimpanzees
provides a unique opportunity to assess the functional role of this duplication
in contributing to variation in social behavior in primates. While our initial
studies show no signs of directional selection on this locus in chimps, pharmacological
and genetic association studies support a potential role for this region in influencing
V1aR expression and social behavior.

text: 'Two key processes are in the basis of morphogenesis: the spatial allocation
of cell types in fields of naïve cells and the regulation of growth. Both are
controlled by morphogens, which activate target genes in the growing tissue in
a concentration-dependent manner. Thus the morphogen model is an intrinsically
quantitative concept. However, quantitative studies were performed only in recent
years on two morphogens: Bicoid and Decapentaplegic. This review covers quantitative
aspects of the formation and precision of the Decapentaplegic morphogen gradient.
The morphogen gradient concept is transitioning from a soft definition to a precise
idea of what the gradient could really do.'

text: We study the mechanics of tissue growth via cell division and cell death (apoptosis).
The rearrangements of cells can on large scales and times be captured by a continuum
theory which describes the tissue as an effective viscous material with active
stresses generated by cell division. We study the effects of anisotropies of cell
division on cell rearrangements and show that average cellular trajectories exhibit
anisotropic scaling behaviors. If cell division and apoptosis balance, there is
no net growth, but for anisotropic cell division the tissue undergoes spontaneous
shear deformations. Our description is relevant for the study of developing tissues
such as the imaginal disks of the fruit fly Drosophila melanogaster, which grow
anisotropically.
