Abstract
Crossbreeding is an efficient means to increase production and quality in plants; however, hybridization is seldom reported in bamboo. We crossbred two bamboo species Phyllostachys kwangsiensis (female parent) and Phyllostachys bambusoides (male parent) for the first time, and obtained suspected bamboo hybrids. We identified two bamboo hybrids from the above parents using PCR/ISSR. We concluded that ISSR markers are useful to identify bamboo hybrids, and that breeding between bamboo species is possible and useful.

Abstract
UNLABELLED Whether depression can increase the risk of bone fractures is uncertain. This meta-analysis, which pooled results from 14 qualifying individual cohort studies, found that depression was associated with a significantly increased risk of fractures and bone loss. INTRODUCTION The effect of depression on the risk of bone fractures is controversial. We conducted a meta-analysis of prospective studies that examined the risk of osteoporotic fractures and bone loss associated with depression. METHODS We searched databases and reviewed citations in relevant articles to identify cohort studies that met prestated inclusion criteria; 14 studies were identified. Information on study design, participant characteristics, exposure and outcome measures, control for potential confounders, and risk estimates was abstracted independently by two investigators using a standardized protocol. Data were pooled by use of a random-effects model. RESULTS In studies that reported fracture outcomes as hazard ratios (HRs) (six studies [n = 108,157]), depression was associated with a 17% increase in fracture risk (HR = 1.17; 95% confidence interval [CI], 1.00-1.36; P = 0.05); in studies that reported risk ratios as fracture outcomes (four studies [n = 33,428]), depression was associated with a 52% increase in risk (risk ratio, 1.52; 95% CI, 1.26-1.85; P < 0.001). In studies that reported bone mineral density as an outcome (five studies [n = 8,931]), depression was associated with a reduced annualized bone loss rate of 0.25% (0.05-0.45%; P = 0.02) at the hip and 0.29% (-0.07-0.64%; P = 0.11) at the spine. The HR for the three studies (n = 14,777) that did not adjust for antidepressant treatment was 1.30 (95% CI, 1.11-1.52; P = 0.01), and the HR for the three studies (n = 93,380) that did adjust for antidepressant treatment was 1.05 (95% CI, 0.86-1.29; P = 0.6). CONCLUSION Evidence supports an association between depression and increased risk of fracture and bone loss that may be mediated by antidepressants.

Abstract
AIMS Betulinic acid has attracted attention in terms of its important biological and pharmacological characteristics. The main objective of this work was to optimize the variables of biotransformation process in order to enhance betulinic acid production from betulin catalysed by fungus Armillaria luteo-virens Sacc ZJUQH100-6. METHODS AND RESULTS Fractional factorial design and response surface methodology were applied to optimize the main parameters that affect betulinic acid production in the growing-cells system. Results indicated that the addition of Tween 80 and substrate concentration were identified as the significant factors on betulinic acid formation, and the central composite experimental design was then adopted to derive a statistical model for optimizing biotransformation conditions. The optimum conditions were observed at pH 6·0, 0·57% Tween 80, 15 mg l(-1) betulin and at 3 days of stage of inoculation. CONCLUSIONS Under the optimized conditions, the highest productivity of betulinic acid predicted was 9·32%, which increased by 74·53% in comparison with that of the nonoptimized. The verified experiment revealed that the model can well simulate betulin biotransformation. Moreover, the bioconversion of betulin and betulin-28-monooxygenase activities was compared between the optimized and the nonoptimized conditions. SIGNIFICANCE AND IMPACT OF THE STUDY Current data imply that betulinic acid production from betulin can be effectively enhanced through biotransformation optimization strategy.

Abstract
In a previous study, we showed that ultrasound can dramatically reduce the time required for tissue fixation in formalin. It generally is believed that ultrasound increases the speed of tissue fixation in two possible ways: 1) increasing the speed of penetration of fixative molecules into tissue samples and 2) increasing the speed of cross-linking reactions. We addressed here the second possible way by using protein solutions and cultured cells, which minimized the effects of the penetration factor. Proteins or cultured cells in solution were fixed with formalin with or without ultrasound irradiation. Fixed proteins and cell lysates then were separated by SDS-poly acrylamide gel electrophoresis and subjected to Western blotting to examine cross-linking formation in certain proteins. Unexpectedly, irradiation with ultrasound did not produce an observable difference in the rate of cross-linking in protein solutions. In similar experiments using cultured cells, however, we observed a significant reduction in recovery of certain proteins from cells fixed by formalin under the influence of ultrasound, which indicated that the ultrasound fixation procedure accelerated cross-linking formation within cells. Studies on protein and cell fixation without ultrasound showed that cross-linking formation was closely related to incubation temperature, which indicates that the heating function, which is inherently associated with ultrasound is another major factor in the ability of ultrasound to accelerate cross-linking.

Abstract
The DNA triple helix consists of a third strand of nucleic acid lying in the major groove of an intact DNA duplex. The most stable triplexes form on polypurine:polypyrimidine sequences, and pyrimidine interruptions in the purine strand are destabilizing. Sequence stringency is imparted by specific Hoogsteen hydrogen bonds between third strand bases and the purine bases in the duplex. Appropriate base and sugar modifications of triple helix-forming oligonucleotides (TFOs) confer chromosome targeting activity in living cells. However, broad utilization of TFOs as gene targeting reagents in mammalian cells has been limited by the requirement for homopurine target sequences. Although there have been a number of base analogues described that appear to be promising as candidates for triplex target expansion, none has been examined in a biological system. We have employed a postsynthetic strategy to prepare a collection of TFOs with base analogues at a defined position. Following assessment of affinity for a triplex target with a single C:G inversion, TFOs with a second generation of analogues were synthesized. One of these, TFO-5a, with 2'-OMe-guanidinylethyl-5-methylcytosine at the position corresponding to the C:G interruption in the target sequence, was further modified to confer bioactivity. The activity of this TFO, linked to psoralen, was measured in a mammalian cell line that was engineered by directed sequence conversion to carry a triplex target with a single C:G interruption. TFO-5a was active against this target and inactive against the corresponding target with an uninterrupted polypurine:polypyrimidine sequence.

Abstract
Collecting duct carcinoma (CDC) or Bellini duct carcinoma of the kidney is a rare, but highly aggressive renal epithelial malignancy, with an extremely poor prognosis. Modified cytokine-induced killer (mCIK) cells were injected into the pleural cavity to treat pleural metastasis of CDC. The patient, a 33-year-old male, was admitted to hospital for further treatment for severe pleural metastasis of CDC. We cured the pleural metastasis through intrapleural infusion with mCIK cells. After receiving this innovative treatment, the patient exhibited a positive response: the cough, dyspnea, chest distress and thoracalgia were evidently relieved, while the pleural fluid became clear after exhibiting haematodes and its level decreased significantly. The patient achieved partial success. This novel immunotherapy method is a promising treatment for patients with refractory pleural metastasis.

Abstract
We report on the fabrication of ferroelectric BaTiO3 thin films on titanium substrates using pulsed laser deposition and their microstructures and properties. Electron microscopy studies reveal that BaTiO3 films are composed of crystalline assemblage of nanopillars with average cross sections from 100 nm to 200 nm. The BaTiO3 films have good interface structures and strong adhesion with respect to Ti substrates by forming a rutile TiO2 intermediate layer with a gradient microstructure. The room temperature ferroelectric polarization measurements show that the as-deposited BTO films possess nearly the same spontaneous polarization as the bulk BTO ceramics indicating formation of ferroelectric domains in the films. Successful fabrication of such ferroelectric films on Ti has significant importance for the development of new applications such as structural health monitoring spanning from aerospace to civil infrastructure. The work can be extended to integrate other ferroelectric oxide films with various promising properties to monitor the structural health of materials.

Abstract
Many TFIIIA-type zinc finger proteins (ZFPs) play important roles in stress responses in plants. In the present study, a novel zinc finger protein gene, StZFP1, was cloned from potato. StZFP1 is a typical TFIIIA-type two-finger zinc finger gene with one B-box domain, one L-box domain and a DLN-box/EAR motif. The StZFP1 genes belong to a small gene family with an estimated copy number of four or five, located on chromosome I. StZFP1 is constitutively expressed in leaves, stems, roots, tubers and flowers of adult plants. Expression of StZFP1 can be induced by salt, dehydration and exogenously applied ABA. StZFP1 expression is also responsive to infection by the late blight pathogen Phytophthora infestans. Transient expression analysis of StZFP1:GFP fusion protein revealed that StZFP1 is preferentially localised in the nucleus. Ectopic expression of StZFP1, driven by the Arabidopsis rd29A promoter in transgenic tobacco, increased plant tolerance to salt stress. These results demonstrate that StZFP1 might be involved in potato responses to salt and dehydration stresses through an ABA-dependent pathway.
