Abstract
OBJECTIVE The prevalence of hemorrhagic transformation (HT) after acute ischemic infarction varies greatly. Risk factors of HT include ageing, severity of stroke, baseline hypertension, high NIH Stroke Scale (NIHSS) scores, hyperglycemia and cardioembolic infarction and low levels of low-density lipoprotein (LDL). We investigated the relationship between LDL, lipid profile and HT after acute ischemic infarction and suggested precautions for HT management. PATIENTS AND METHODS Three hundred and forty-eight patients with acute infarction were included in the study. Fasting lipid profile was examined on the next morning following hospitalization. Either MRI GRE-T2*WI or CT was performed, one week after hospitalization to detect any cerebral microbleed (CMB) and hemorrhagic transformation. The lipid profiles examined included total cholesterol (TCH), triglyceride (TG), LDL and high-density lipoprotein (HDL). RESULTS Among all the patients, HT was noted in 35 patients and non-HT in 313. As compared with non-HT group, HT group had lower levels of TCH, HDL and LDL, lower rates of leukoaraiosis and CMB, but higher scores of NIHSS, higher rates of diabetes mellitus, atrial fibrillation and urokinase thrombolysis. The multivariate binary logistic regression showed that cardioembolic infarction, infarction with undetermined etiology, high scores of NIHSS and diabetes were the risk factors of HT, while the protective factor was LDL (OR=0.654, 95% CI: 0.430-0.996, p=0.048). CONCLUSIONS Low level of LDL is likely associated with increased HT after acute ischemic infarct, so for those patients with low level of LDL, high scores of NIHSS and cardioembolic infarction at admission, aggressive lipid- lowering treatment should be prescribed cautiously to prevent the incidence of HT.

Abstract
BACKGROUND AND PURPOSE Secondary cortical thinning and volumetric atrophy in the motor-related cortex can inhibit early functional recovery after subcortical infarction. However, the relationship between the spontaneous neuronal activity in these cortices and motor recovery in patients with focal cerebral infarct remains unknown. METHODS Structural magnetic resonance imaging (MRI) and resting-state functional MRI were conducted 1, 4 and 12 weeks after onset in 22 patients with an acute subcortical infarct and in 22 normal subjects. Group differences in cortical thickness and in the amplitude of low-frequency fluctuation (ALFF) in motor-related areas were evaluated, and the relationships between ALFF, cortical thickness changes and changes in the Fugl-Meyer scores of physical performance were further analyzed. RESULTS In patients with subcortical infarction, progressively decreasing cortical thickness was found over the observation period ipsilesionally in the primary motor cortex (PMC), supplementary motor cortex (SMC) and precuneus (all P < 0.05). Contralesionally, progressive increases in cortical thickness were detected in SMC and insula (all P < 0.05). Increases in ALFF were observed only in PMC (bilaterally) and only at 12 weeks after stroke (all P < 0.05). The cortical thickness changes in the contralesional SMC (rs = 0.483, P = 0.023) and the ALFF changes in bilateral PMC (ipsilesional, rs = 0.51, P = 0.015; contralesional, rs = 0.463, P = 0.03) were positively correlated with changes in the Fugl-Meyer scores. CONCLUSIONS These results suggest that increased spontaneous neuronal activity of the PMC, a region structurally damaged secondarily to ischaemic lesion, may contribute to early motor recovery in patients with subcortical infarction.

Abstract
Protein functions that are mediated by interaction with other proteins (protein-protein interactions, PPI) are important for normal cell biology and also in disease. Molecules that can interfere with PPI are required as laboratory tools to dissect function, as lead drug surrogates for target validation and as templates for drug discovery. We describe enhanced developments to Intracellular Antibody Capture (IAC) technology that can select antibody fragments able to interact with targets in cells. This is illustrated by the isolation of single heavy chain variable region domains binding to the basic-helix-loop-helix and leucine zipper region of the CMYC oncogenic protein. The enhanced IAC (eIAC) methodology deploys screening in yeast cells of a single diverse library initially with randomization only of CDR3. Further sequential randomization of CDR2 and CDR1 of three independently selected anti-CMYC clones illustrates an in vivo affinity maturation process. This concise eIAC approach facilitates the rapid selection of antibody fragments to explore the proteome interaction spectrum of mammalian cells and disease targeting.

Abstract
The Asian citrus psyllid (ACP), Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is the only natural vector of Candidatus Liberibacter asiaticus that causes citrus huanglongbing (HLB), a most destructive disease of citrus. Currently, no remedial therapy exists for the disease, and so effective control of ACP is very important in curbing the transmission of the disease. The push-pull strategy should be thoroughly explored as an approach to ACP management. This mini-review summarises the current progress towards more effective repellent and attractant chemicals through investigating known repellent and attractive plants. Interactions between ACP and its host plants are also addressed, with emphasis on the possible involvement of the host biochemicals in attracting the insect. Potential ways to increase the effectiveness of the pull-push strategy are briefly discussed. It is expected that the pull-push strategy will be gradually developed following more extensive research.

Abstract
Hemoglobin (Hb) is a major constituent of blood and a potent mediator of oxidative or nitrative stress after intracerebral hemorrhage (ICH). Our previous study demonstrated that Hb could induce abundant peroxynitrite (ONOO(-)) formation in vivo, which may be involved in the blood-brain barrier (BBB) disruption, however, the drug intervention is absent and also the underlying mechanism. Using an experimental stroke model by injecting Hb into the caudate nucleus of male Sprague-Dawley rats, we assessed the role of ONOO(-) decomposition catalyst, 5,10,15,20-tetrakis (4-sulfonatophenyl) porphyrinato iron(III) [FeTPPS] in the activation of MMP-9 and Hb-induced neurovascular injuries. 3-Nitrotyrosine (3-NT, as an index of ONOO(-) formation) and NF-κB expression was measured by western blot (WB) and immunohistochemistry (IHC)/immunofluorescence (IF). Activity of MMP was evaluated by in situ zymography. Neurovascular injury was assessed using zonula occludens-1 (ZO-1) by WB and IF, fibronectin (FN) and neuron-specific nuclear protein (NeuN) IHC. Perihematomal cell death was determined by TUNEL assay. Behavioral outcome was measured by modified neurological severity score (mNSS) test. At the injured striata, profuse 3-NT was produced and mainly expressed in neutrophils and microglia/macrophages. 3-NT formation significantly colocalized with nuclear factor-κB (NF-κB) expression. In situ zymography showed that gelatinase activity was mostly co-localized with neurons and blood vessel walls and partly with neutrophils and microglia/macrophages. Enhanced 3-NT production, NF-κB induction and MMP-9 activation were obviously reduced after FeTPPS treatment. Hb-induced injury to tight junction protein (ZO-1), basal lamina of FN-immunopositive microvasculature and neural cells was evidently ameliorated by FeTPPS. In addition, apoptotic cell numbers as well as behavioral deficits were also improved. The present study shows that the administration of the ONOO(-) decomposition catalyst FeTPPS protects against Hb-induced neurovascular injuries and improves neurological function, which possibly in part by suppressing MMP-9 activation.

Abstract
Ovarian cancer is a lethal gynecologic malignancy and always has a poor prognosis. Despite new treatments modalities, the long term outcomes had not been significantly improved in the past 30 years. Although microRNA-200a (miR-200a) has been reported to be a prognostic marker in ovarian cancer, it's exact role in ovarian cancer remain unclear. In this study, we inserted the response element of miR-200a in ovarian cancer cell line via lentivirus-mediated transgene in vitro, and qRT-PCR (real time quantitative reverse transcription PCR) assay confirmed that miR-200a was up regulated compared with control. Then colony-formation assay, cell cycle analysis, CCK8 assays in vitro and xenograft experiments in vivo were performed and verified that miR-200a promoted proliferation, while blocked the formation of tumor spheroids and reduced the ratio of SP (side population) cells in ovarian cancer. Finally, we invalidated that miR-200a significantly enhanced the chemosensitivity of paclitaxel but not cisplatin in both adherent culture and sphere culture. Taken together, we demonstrated that upregulation miR-200a promoted proliferation and inhibited CSCs phenotype in OVCAR-3 ovarian cancer cell line, combined with cell cycle-targeting drug paclitaxel could effectively eliminate the "side effects" of proliferation, and showed evidences that this strategy may be promising for ovarian cancer treatment.

Abstract
The characteristics of scattering due to interface roughness are usually described by the backscattering matrix for reverberation modeling. The backscattering matrix based on the Bass perturbation theory has significant differences from that based on the empirical scattering rule (Lambert's rule), especially at low grazing angles. In a waveguide environment with a point source, it is very difficult to extract the quantitative characteristics of the backscattering matrix at low grazing angles from the experimental data because of the difficulties in acquiring low-grazing-angle scattering data and separating the scattering data between different modes (grazing angles). In contrast, the use of single-mode excitations as sources in shallow-water waveguides enables acquisition of good quality low-grazing-angle scattering data. In this paper, the characteristics of the backscattering matrix were obtained from different single-mode reverberation experiments in shallow-water. The experiments were carried out at different sites during different seasons off the coasts of China. Model-data comparisons were made and the results showed that at low grazing angles (2°-5°), the backscattering matrices based on the Bass perturbation theory were in good agreement with the experimental data, but the backscattering matrices based on Lambert's rule were not.
