Abstract	We point out new ways to search for charmless baryonic B decays and suggest that enhanced baryon production is favored by reduced energy release on the baryon side. Thus B-->eta(')+baryon pairs might be larger than Kpi/pipi modes; the argument may be extended to B-->gamma+X(s), and perhaps to lnu+X(u). Guess estimates give some branching ratios in the 10(-3)- 10(-6) range, with confidence gained from the recent observation of B-->D()pn, D()pppi not far below D()pi and D()rho rates. Observation of modes proposed here would help clarify the dynamics of weak decays involving baryons, while the self-analyzing prowess of Lambda decay can be helpful in CP- and T-violation studies.

Abstract	The mixings of d(R) quarks, hidden from view in the standard model (SM), are naturally the largest if one has an Abelian flavor symmetry. With supersymmetry (SUSY) their effects can surface via d(R) squark loops. Squark and gluino masses are at TeV scale, but they can still induce effects comparable to SM in B(d) (or B(s)) mixings, while D0 mixing could be close to recent hints from data. In general, CP phases would be different from SM, as may be indicated by recent B factory data. Presence of nonstandard soft SUSY breakings with large tanbeta could enhance b-->dgamma (or sgamma) transitions.

Abstract	Therapeutic options for hypoxic-ischemic brain damage (HIBD) are scarce and inefficient. Recently, many studies have demonstrated that red photon plays an important role in anti-inflammatory processes as well as apoptosis, the main trait of HIBD. In this study, we investigated whether red photon can protect from HIBD in SD rats and oxygen-glucose deprivation (OGD) in PC12 cells. Apoptosis, mitochondrial transmembrane potential (MMP), and reactive oxygen species (ROS) rates were assessed in PC12 cells. We found that 6-h irradiation resulted in decreased MMP, ROS and apoptosis rates, although these changes were reversible with prolonged irradiation. Importantly, these effects were sustained for 2-8h upon quenching of the red photon. Similar trends were observed for protein and mRNA expression of bax and bcl-2, with short-term irradiation (6h) inhibiting apoptosis in PC12 Cells. However, long-term (>6h) irradiation caused cell damage. In vivo experiments, bax mRNA and protein levels were reduced after 7days in HIBD model rats treated with red photon, in contrast to bcl-2. Furthermore, we found that bax and bcl-2 were mainly expressed in pyramidal cells of the hippocampus CA1 and CA3. Importantly, Morris Water Maze test results revealed an improvement in learning ability and spatial memory in rats after irradiation. Overall, our data showed that short-term irradiation with red photon in the acute phase inhibits the mitochondrial apoptotic pathway via regulation of bcl-2-related proteins and reduction of ROS levels, thereby decreasing apoptosis in nerve cells and improving the neurological prognosis of HIBD.

Abstract	Multitendoned extrinsic muscles of the human hand can be divided into several neuromuscular compartments (NMCs), each of which contributes to the ability of human finger to produce independent finger movements or force. The aim of this study was to investigate the changes in the spatial activation of flexor digitorum superficialis (FDS) during the fingertip force production with non-invasive multichannel surface electromyography (sEMG) technique. 7 healthy Subjects were instructed to match the target force level for 5s using individual index finger (I), individual middle finger (M) and the combination of the index and middle finger (IM) respectively. Simultaneously, a 2 × 6 electrode array was employed to record multichannel sEMG from FDS as finger force was produced. The entropy and center of gravity of the sEMG root mean square (RMS) map were computed to assess the spatial inhomogeneity in muscle activation and the change in spatial distribution of EMG amplitude related to the force generation of specific task finger. The results showed that the area and intensity of high amplitude region increased with force production, and the entropy increased with force level under the same task finger. The findings indicate that the change of spatial distribution of multitendoned extrinsic hand muscle activation is correlated to specific biomechanical functions.

Abstract	Cathepsin K is the predominant cysteine protease in osteoclast-mediated bone remodeling, and the protease is thought to be involved in the pathogenesis of diseases with excessive bone and cartilage resorption. Osteoclastic matrix degradation occurs in the extracellular resorption lacuna and upon phagocytosis within the cell's lysosomal-endosomal compartment. Since glycosaminoglycans (GAGs) are abundant in extracellular matrixes of cartilage and growing bone, we have analyzed the effect of GAGs on the activity of bone and cartilage-resident cathepsins K and L and MMP-1. GAGs, in particular chondroitin sulfates, specifically and selectively increased the stability of cathepsin K but had no effect on cathepsin L and MMP-1. GAGs strongly enhanced the stability and, to a lesser extent, the catalytic activity of cathepsin K. To combine the activity and stability parameters, we defined a novel kinetic term, named cumulative activity (CA), which reflects the total substrate turnover during the life span of the enzyme. In the presence of chondroitin-4-sulfate (C-4S), the CA value increased 200-fold for cathepsin K but only 25-fold with chondroitin-6-sulfate (C-6S). C-4S dramatically increased the hydrolysis of soluble as well insoluble type I and II collagens, whereas the effects of C-6S and hyaluronic acid were less pronounced. C-4S acts in a concentration-dependent manner but reaches saturation at approximately 0.1%, a concentration similar to that found in the synovial fluid of arthritis patients. C-4S increased the cathepsin K-mediated release of hydroxyproline from insoluble type I collagen 10-fold but had only a less than 2-fold enhancing effect on the hydrolysis of intact cartilage. The relatively small increase in the hydrolysis of cartilage by C-4S was attributed to the endogenous chondroitin sulfate content present in the cartilage. Although C-4S increased the pH stability at neutral pH, a significant increase in the collagenolytic activity of cathepsin K at this pH was not observed, thus suggesting that the unique collagenolytic activity of cathepsin K at acidic pH is mechanistically determined and not by the enzyme's instability at neutral pH. The selective and significant stabilization and activation of cathepsin K activity by C-4S may provide a rationale for a novel mechanism to regulate the enzyme's activity during bone growth and aging, two processes known for significant changes in the GAG content.

Abstract	The rare osteosclerotic disease, pycnodysostosis, is characterized by decreased osteoclastic bone collagen degradation due to the absence of active cathepsin K. Although this enzyme is primarily expressed by osteoclasts, there is increasing evidence that it may also be present in other cells, including fibroblasts. Since fibroblasts are known to degrade collagen intracellularly following phagocytosis, we analyzed various soft connective tissues (periosteum, perichondrium, tendon, and synovial membrane) from a 13-week-old human fetus with pycnodysostosis for changes in this collagen digestion pathway. In addition, the same tissues from cathepsin K-deficient and control mice were analyzed. Microscopic examination of the human fetal tissues showed that cross-banded collagen fibrils had accumulated in lysosomal vacuoles of fibroblasts. Morphometric analysis of periosteal fibroblasts revealed that the volume density of collagen-containing vacuoles was 18 times higher than in fibroblasts of control patients. A similar accumulation was seen in periosteal fibroblasts of three children with pycnodysostosis. In contrast to the findings in humans, an accumulation of internalized collagen was not apparent in fibroblasts of mice with cathepsin K deficiency. Our observations indicate that the intracellular digestion of phagocytosed collagen by fibroblasts is inhibited in humans with pycnodysostosis, but probably not in the mouse model mimicking this disease. The data strongly suggest that cathepsin K is a crucial protease for this process in human fibroblasts. Murine fibroblasts may have other proteolytic activities that are expressed constitutively or up regulated in response to a deficiency of cathepsin K. This may explain why cathepsin K-deficient mice lack the dysostotic features that are prominent in patients with pycnodysostosis.

Abstract	Synovial fibroblasts (SFs) play a critical role in the pathogenesis of rheumatoid arthritis (RA) and are directly involved in joint destruction. Both SF-resident matrix metalloproteases and cathepsins have been implicated in cartilage degradation although their identities and individual contributions remain unclear. The aims of this study were to investigate the expression of cathepsin K in SFs, the correlation between cathepsin K expression and disease severity, and the contribution of cathepsin K to fibroblast-mediated collagen degradation. Immunostaining of joint specimens of 21 patients revealed high expression of cathepsin K in SFs in the synovial lining and the stroma of synovial villi, and to a lesser extent in CD68-positive cells of the synovial lining. Cathepsin K-positive SFs were consistently observed at sites of cartilage and bone degradation. Expression levels of cathepsin K in the sublining and vascularized areas of inflamed synovia showed a highly significant negative correlation with results derived from the Hannover Functional Capacity Questionnaire (r = 0.78, P = 0.003; and r = 0.70, P = 0.012, respectively) as a measure of the severity of RA in individual patients. For comparison, there was no correlation between Hannover Functional Capacity Questionnaire and cathepsin S whose expression is limited to CD-68-positive macrophage-like synoviocytes. The expression of cathepsin K was also demonstrated in primary cell cultures of RA-SFs. Co-cultures of SFs on cartilage disks revealed the ability of fibroblast-like cells to phagocytose collagen fibrils whose intralysosomal hydrolysis was prevented in the presence of a potent cathepsin K inhibitor but not by an inhibitor effective against cathepsins L, B, and S. The selective and critical role of cathepsin K in articular cartilage and subchondral bone erosion was further corroborated by the finding that cathepsin K has a potent aggrecan-degrading activity and that cathepsin K-generated aggrecan cleavage products specifically potentiate the collagenolytic activity of cathepsin K toward type I and II collagens. This study demonstrates for the first time a critical role of cathepsin K in cartilage degradation by SFs in RA that is comparable to its well-known activity in osteoclasts.

Abstract	VE161 wheat which has the function of promotting homoeologous pairing is a male sterile substitution line or a fertile addition line with one pair of alien chromosomes from Agropyron elongatum. The alien chromosome in VE161 wheat was detected by means of techniques of total genomic DNA in situ hybridization, RFLP and double-ditelo chromosomal analysis. The results from in situ hybridization confirmed that the alien chromosome was derived from Agropyron elongatum. The RFLP analysis showed that it belongs to fourth homoeologous group, and the results from double-ditelo chromosomal analysis gave evidence that 4B chromosome was replaced in the substitution line, so it can be concluded that, in VE161 wheat, the alien chromosome would be 4E and the replaced wheat chromosome would be 4B in the substitution line. The reason for the replaced chromosome identified as 7B in a earlier study might be due to the rearrangement occurred in the genome of wheat.

Abstract	The first simultaneous determination of the absolute value of the Cabibbo-Kobayashi-Maskawa matrix element V_{ub} using inclusive and exclusive decays is performed with the full Belle data set at the ϒ(4S) resonance, corresponding to an integrated luminosity of 711 fb^{-1}. We analyze collision events in which one B meson is fully reconstructed in hadronic modes. This allows for the reconstruction of the hadronic X_{u} system of the semileptonic b→uℓν[over ¯]_{ℓ} decay. We separate exclusive B→πℓν[over ¯]_{ℓ} decays from other inclusive B→X_{u}ℓν[over ¯]_{ℓ} and backgrounds with a two-dimensional fit that utilizes the number of charged pions in the X_{u} system and the four-momentum transfer q^{2} between the B and X_{u} systems. Combining our measurement with information from lattice QCD and QCD calculations of the inclusive partial rate as well as external experimental information on the shape of the B→πℓν[over ¯]_{ℓ} form factor, we determine \|V_{ub}^{excl}\|=(3.78±0.23±0.16±0.14)×10^{-3} and \|V_{ub}^{incl}\|=(3.88±0.20±0.31±0.09)×10^{-3}, respectively, with the uncertainties being the statistical error, systematic errors, and theory errors. The ratio of \|V_{ub}^{excl}\|/\|V_{ub}^{incl}\|=0.97±0.12 is compatible with unity.

Abstract	We study B^{+}→π^{+}π^{0}π^{0} using 711 fb^{-1} of data collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. We measure an inclusive branching fraction of (19.0±1.5±1.4)×10^{-6} and an inclusive CP asymmetry of (9.2±6.8±0.7)%, where the first uncertainties are statistical and the second are systematic, and a B^{+}→ρ(770)^{+}π^{0} branching fraction of (11.2±1.1±0.9_{-1.6}^{+0.8})×10^{-6}, where the third uncertainty is due to possible interference with B^{+}→ρ(1450)^{+}π^{0}. We present the first observation of a structure around 1 GeV/c^{2} in the π^{0}π^{0} mass spectrum, with a significance of 6.4σ, and measure a branching fraction to be (6.9±0.9±0.6)×10^{-6}. We also report a measurement of local CP asymmetry in this structure.
