Reducing the risk of tooth injury in anterior maxillary interdental osteotomy for cleft lip and palate patients using a surgical navigation technique. Int J Oral Maxillofac Surg 2024; 53:368-375. [PMID: 37805371 DOI: 10.1016/j.ijom.2023.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2022] [Revised: 09/07/2023] [Accepted: 09/25/2023] [Indexed: 10/09/2023]
Abstract
The aim of this study was to investigate the clinical feasibility of preventing tooth injury from anterior maxillary interdental osteotomy by using a surgical navigation technique. A retrospective review was conducted on cleft lip and palate patients treated with anterior maxillary osteotomy followed by distraction osteogenesis between August 2019 and May 2022. Patients operated on through image guidance were enrolled in the navigation group, while those who were operated on freehand were enrolled in the freehand group. Tooth injuries were identified on postoperative images. Linear and angular deviations of the osteotomy line were measured. Twelve patients were enrolled in the study, seven in the navigation group and five in the freehand group. Altogether, 24 osteotomy lines and 53 adjacent teeth were evaluated. The dental injury rate was 3% in the navigation group and 27% in the freehand group (P = 0.016). The average linear deviations (mean ± standard deviation) were 0.67 ± 0.30 mm and 2.05 ± 1.33 mm, respectively (P < 0.001), while the average angular deviations were 1.67 ± 0.68° and 11.41 ± 7.46°, respectively (P < 0.001). The results suggest that navigation was able to reduce the tooth injury risk compared with freehand interdental osteotomies in crowded dental arches.

Abstract
Immediate implant placement has the advantages of shortening the operation time, reducing the treatment cycle and cost. At present, this technology has been used widely, but the indications of immediate implantation are still limited. Here, a novel type of root analog implant (RAI) was manufactured by selective laser melting technology to address the limitation. Under optimized condition, RAIs were printed with the internal density of 99.73% and the uniform surface roughness of 11 μm (Sa). Besides, the deviation between RAI specimen and design models is controlled within 0.15 mm after optimizing scanning parameters. The substrate printed could promote human bone marrow stromal cell proliferation, spreading, and osteogenic differentiation. The bone-implant contact (BIC, 75% ± 7%) and bone volume/total volume (BV/TV, 74% ± 7%) of RAIs were significantly higher than that of conventional implants (BIC, 66% ± 5%; BV/TV, 62% ± 5%) in in vivo experiments. Further, customized abutments were designed for the RAIs, improving the masticatory ability of the beagle dogs after crown restoration. This study aims to design a personalized 2-stage RAI with compact structure and uniform roughness, in order to achieve better fracture resistance, initial osseointegration efficiency, and dispersed stress in immediate implantation. It provides a certain guiding value for standardizing the manufacture and clinical application of RAI in immediate implantation.

An objective, quantitative, dynamic assessment of facial movement symmetry changes after orthognathic surgery. Int J Oral Maxillofac Surg 2023; 52:272-281. [PMID: 35753942 DOI: 10.1016/j.ijom.2022.06.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 06/10/2022] [Accepted: 06/13/2022] [Indexed: 01/11/2023]
Abstract
The aim of this study was to generate a quantitative dynamic assessment of facial movement symmetry changes after orthognathic surgery. Twenty-five patients diagnosed with skeletal class III malocclusion with facial asymmetry who underwent bimaxillary surgery were recruited. The patients were asked to perform a maximum smile that was recorded using a three-dimensional facial motion capture system preoperatively (T0), 6 months postoperatively (T1), and 12 months postoperatively (T2). Eleven facial landmarks were selected to analyse the cumulative distance and average speed during smiling. The absolute differences for the paired landmarks between the sides were analysed to reflect the symmetry changes. The results showed that the asymmetry index of the cheilions at T2 was significantly lower than that at T0 (P = 0.004), as was the index of the mid-lateral lower lips (P = 0.006). The mean difference in cheilions was 2.13 ± 1.41 mm at T0, 1.33 ± 1.09 mm at T1, and 1.00 ± 0.98 mm at T2. The facial total mobility at T1 was significantly lower than that at T0 (P < 0.001), while the total mobility at T2 was significantly higher than that at T1 (P = 0.012). The orthognathic surgical correction of facial asymmetry was able to improve the associated asymmetry of facial movements.

Abstract
Poly(heptazine imide) (PHI), one of the attractive allotropes of polymeric carbon nitride, has recently received extensive attention in photocatalysis due to its extended conjugation for fast separation and transfer of the charges. However, pristine PHI bears an intrinsic optical absorption band edge at 460 nm, which largely restrains the visible light utilization. Herein, the narrow-bandgap PHI (N-PHI) with an ordered-distorted interface was fabricated from polycondensation of the mixture of NaSCN, cyanuric chloride, and LiCl. Results revealed that the enhanced optical absorption and the promoted separation and transfer of the charge carriers at the interface greatly improved the photocatalytic performance, which endowed N-PHI with an apparent quantum yield of 20 % for hydrogen production at 450 nm.

Abstract
Alveolar echinococcosis, caused by Echinococcus multilocularis infection, is a highly deadly zoonotic parasitic disease. As a benzimidazole compound, albendazole has a strong and broad-spectrum anti-parasitic action. For alveolar echinococcosis patients that are unwilling to receive surgical treatment, lose the timing for surgery, or are intolerant to surgery due to poor physical status, administration of albendazole may delay disease progression. Recently, a large number of advances have been achieved in experimental studies on alveolar echinococcosis. In order to increase the understanding of the therapeutic efficacy of albendazole for alveolar echinococcosis, this review summarizes the advances in albendazole treatment for alveolar echinococcosis, so as to provide insights into the clinical treatment of alveolar echinococcosis with albendazole.

Abstract
As an important influencing factor of construction workers' safety performance, safety stressor has received increasing attention. However, no consensus has been reached on the relationship between different types of safety stressors and the subdimensions of safety performance, and the mechanism by which safety stressors influence safety performance remains unclear. This study proposed a multiple mediation model with ego depletion and self-efficacy as mediators between safety stressors and workers' safety performance. Data were collected from 335 construction workers in China. Results demonstrated that: (1) the three types of safety stressors (i.e., safety role ambiguity, safety role conflict, and interpersonal safety conflict) all had negative effects on workers' safety performance (i.e., safety compliance and safety participation); (2) self-efficacy mediated all the relationships between the three safety stressors and safety performance; (3) ego depletion only mediated part of the relationships between the three safety stressors and safety performance; and (4) only part of the multiple-step mediating effects through ego depletion and self-efficacy were supported. This study made contributions by shedding light on the mechanism by which safety stressors influence workers' safety performance and providing more empirical evidence for the relationship between various safety stressors and the subdimensions of safety performance. Additionally, targeted strategies for improving workers' safety performance were proposed according to the findings.

Abstract
A systematic review of the literature was conducted to assess the safety and efficacy of endoscope-assisted maxillary sinus elevation. PubMed, Embase, Web of Science, and the Cochrane database were searched for articles in English. Published studies involving patients who had undergone endoscope-assisted maxillary sinus floor augmentation were selected. The validity of the included articles was evaluated. After going through full texts, a total of 12 studies met the eligibility criteria and were included. It was concluded that endoscope-controlled maxillary sinus floor elevation was a viable and beneficial method, providing direct visualisation of the integrity of the mucosa and placing of bone graft material. The endoscope could be inserted into the maxillary sinus lumen, subantral space below the Schneiderian membrane, or through the alveolar crest. With the endoscope, perforations can be detected and managed precisely. However, high-quality clinical trials are still needed to validate the predictability and advantages of this surgical procedure.

Abstract
Zinc (Zn) is an indispensable element for rice growth. Zn deficiency results in brown blotches and streaks 2-3 weeks after transplanting, as well as stunting, reduced tillering, and low productivity of rice plants. These processes are controlled by different families of expressed genes. A comparative transcriptome profile analysis was conducted using the roots of two Zn deficiency tolerant varieties (UCP122 and KALIBORO26) and two sensitive varieties (IR26 and IR64) by merging data from untreated control (CK) and Zn deficiency treated samples. Results revealed a total of 4,688 differentially expressed genes (DEGs) between the normal Zn and deficient conditions, with 2,702 and 1,489 unique DEGs upregulated and downregulated, respectively. Functional enrichment analysis identified transcription factors (TFs), such as WRKY, MYB, ERF, and bHLH which are important in the regulation of the Zn deficiency response. Furthermore, chitinases, jasmonic acid, and phenylpropanoid pathways were found to be important in the Zn deficiency response. The metal tolerance protein (MTP) genes also appeared to play an important role in conferring tolerance to Zn deficiency. A heavy metal-associated domain-containing protein 7 was associated with tolerance to Zn deficiency and negatively regulated downstream genes. Collectively, our findings provide valuable expression patterns and candidate genes for the study of molecular mechanisms underlying the response to Zn deficiency and for improvements in breeding for tolerance to Zn deficiency in rice.

Abstract
The recent coronavirus outbreak has captured worldwide attention. This study investigated the anxiety of the Chinese public and its relationship with social support during the early stage of the COVID-19 pandemic, thereby providing empirical support for interventions on improving the public's mental health. On the basis of an online questionnaire survey conducted on 10-18 February 2020, this study shows that 19.8%, 68.5%, and 11.1% of the respondents suffered mild anxiety, moderate anxiety, and severe anxiety, respectively. Significant differences are reported in state anxiety between people with different household incomes. There are significant differences in trait anxiety and state anxiety between different social support groups. Social support and trait anxiety are negatively correlated. Social support and state anxiety are negatively correlated. Social support affects state anxiety both directly and indirectly (through the mediation of trait anxiety). Therefore, during the COVID-19 pandemic, increasing public support for society can effectively reduce public anxiety.

Antecedents of safety behavior in construction: A literature review and an integrated conceptual framework. ACCIDENT; ANALYSIS AND PREVENTION 2020; 148:105834.

Abstract
There has been no scarcity in the literature of suggested antecedents of employee safety behavior, and this paper brings together the disaggregated antecedents of safety behavior in the construction field. In total, 101 eligible empirical articles are obtained. Bibliometric and context analyses are combined to identify the influential journals, scholars, keywords, use of theory, research methods, and countries or regions of the empirical samples. The 83 factors that are identified are divided into five groups, namely (a) individual characteristics, (b) workgroup interactions, (c) work and workplace design, (d) project management and organization, and (e) family, industry, and society. This indicates that the causes of safety behavior are manifold. Various factors from different systems likely work in concert to create situations in which an individual chooses to comply with safety rules and participate voluntarily in safety activities. Given this, we propose that safety behavior is only an ostensible symptom of more complex "The Self-Work-Home-Industry/Society" systems and establish a safety behavior antecedent analysis and classification model. Based on this model, we develop a resource flow model, illustrating why, how, and when the flow of resources between the five systems-namely the self system, work system, home system, work-home interface system, and industry/society system-either promotes or inhibits safety behavior. The safety behavior antecedent analysis and classification model and resource flow model are based mainly on bioecological system theory and resources theories. Avenues for future theoretical development and method designs are suggested based on the reviewed findings and the two conceptual models. The intention with this systematic review together with the two integrated conceptual models is to advance theoretical thinking on how safety behavior can be promoted, or instead, inhibited.

Abstract
Objective: To evaluate the prognostic value of different critical care scoring systems in 28-day survival rate of patients with heat stroke. Methods: A retrospective analysis was conducted on the clinical data of 71 patients with heat stroke admitted to the department of emergency medicine of Beijing Luhe Hospital. Capital Medical University from July 2015 to September 2018. The general information and the worst values of vital signs and related pathophysiological indicators within 24 hours were collected and the sequential organ failure assessment (SOFA) , multiple organ dysfunction (MODS) , simplified acute physiological scoreⅡ (SAPS Ⅱ) and acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) were calculated. The patients were divided into the survival group (n=45) and the non-survival group (n=26) according to 28-day prognosis, and the clinical data and scores of the two groups were compared.The ROC curve was drawn to analyze the evaluation value of each scoring system on the survival rate of patients at 28-day. Kaplan-Meier method was used to plot the survival curve of patients. Results: There were no significant differences in age, sex, vital signs and laboratory parameters between two groups (P>0.05) . In non-survival patients, SOFA, SAPS Ⅱ, APACHE Ⅱ scores were significantly elevated in the survival group (P<0.05) . ROC curve analysis showed that the area under ROC curve (AUC) of SOFA score for predicting 28-day survival rate was the highest, which was significantly higher than the APACHE Ⅱ, SAPS Ⅱ, MODS score. When the best cut-off value of SOFA score was 9.0, the sensitivity was 84.6%, and the specificity was 71.1%. Kaplan-Meier survival analysis showed that 28-day survival rate after hospital discharge in patients with SOFA score<9 (n=27) was significantly higher than that in patients with SOFA score ≥9.0 (χ(2)=1.0, P<0.01) . Conclusion: SOFA, APACHE Ⅱ, SAPS Ⅱ on admission have been proved to have good prognostic ability to predict 28-day prognosis in heat stroke patients. Among them, SOFA score system has more accurate prediction value.

Abstract
BACKGROUND Multi-drug resistant (MDR) Pseudomonas aeruginosa can negatively affect patients and hospitals. AIM To evaluate excess mortality and cost burden among patients hospitalized with suspected respiratory infections due to MDR P. aeruginosa vs patients with non-MDR P. aeruginosa in 78 United States (US) hospitals. METHODS This study analyzed electronically captured microbiological and outcomes data of patients hospitalized with non-duplicate P. aeruginosa isolates from respiratory sources collected ≥3 days after admission to identify hospital-onset MDR or non-MDR P. aeruginosa per the Centers for Disease Control and Prevention definition. The risk of multi-drug resistance was estimated on mortality, length of stay (LOS), cost, operation gain/loss, and 30-day readmission. A sensitivity analysis was conducted utilizing a cohort with pharmacy data available. FINDINGS Of 523 MDR and 1381 non-MDR P. aeruginosa cases, unadjusted mortality was 23.7% vs 18.0% and multi-variable-adjusted mortality was 20.0% (95% confidence interval (CI): 14.3-27.2%) vs 15.5% (95% CI: 11.2-20.9%; P=0.026), the average adjusted excess LOS was 6.7 days (P<0.001); excess cost per case was US$22,370 higher (P=0.002) and operational loss per case was US$10,661 (P=0.024) greater, and the multi-variable adjusted readmission rate was 16.2% (95% CI: 11.2-22.9%) vs 11.1% (95% CI: 7.8-15.6%; P=0.006). The sensitivity analysis yielded similar results. CONCLUSIONS Compared with suspected infections due to non-MDR P. aeruginosa, patients with MDR P. aeruginosa had higher risk of mortality, readmission, and longer LOS, as well as US$20,000 incremental cost and >US$10,000 incremental net loss per case after controlling for patient and hospital characteristics.

Efficient treatment of brine wastewater through a flow-through technology integrating desalination and photocatalysis. WATER RESEARCH 2019; 157:134-144.

Abstract
Many current treatments for brine wastewaters are energy-intensive, chemical-intensive, and involve independent process in the removal of salts and contaminants. We demonstrate that through the integration of capacitive deionization and photocatalysis reactions within carbon nanotubes (CNTs) based membrane system, we are able to realize the purification and desalination of wastewaters via single-step, energy-efficient, and environmentally friendly route. We firstly designed the membrane system consisting of graphitic carbon nitride (g-C3N4), CNTs membrane, and poly(vinyl alcohol)-formaldehyde (PVF) foam. Then, two identical membrane systems were used as permeable electrodes and photocatalytic microreactors to construct the flow-through setup. The tests of the setup with a variety of dye solution, antibiotics solution, and actual wastewaters prove that wastewaters passing through the setup promptly turn to clean water with significantly decreased salinity. This is because the setup can use C3N4 modified CNTs membrane to adsorb organic contaminants and inorganic ions and decompose contaminants via photocatalysis reactions. In addition, by discharging the setup, its adsorption capacity towards salts is easily recovered. Consequently, the flow-through setup is observed to exhibit stable performance for concurrent removal of organic contaminants and inorganic salts in multiple cycles.

Abstract
AIM We aimed to evaluate the association between selective COX-2 inhibitors (coxibs) and the risk of colorectal neoplasms and vascular events with and without low-dose aspirin. METHOD We searched for randomized controlled trials and comparative studies in PubMed, EMBASE and Cochrane Library databases using pertinent key terms. Risk ratios (RRs) were calculated for each study with a fixed- or random-effects model. RESULTS Eight clinical studies with 44 566 subjects were eligible. The use of coxib significantly reduced the overall risk of colorectal neoplasms by 21% (RR = 0.79, 95% CI 0.70-0.89; P = 0.000). The chemopreventive effect of coxibs was beneficial in the first year (RR = 0.74, 95% CI 0.58-0.94; P = 0.013), marginal in the third year (RR = 0.79, 95% CI 0.63-1.01; P = 0.059) and counterproductive in the fifth year (RR = 1.65, 95% CI 1.23-2.21; P = 0.001). Compared with the use of aspirin alone, combined use of coxib and aspirin for 3 years increased the risk of a colorectal neoplasm by 80% in the fifth year (RR = 1.80, 95% CI 1.22-2.66; P = 0.003) but decreased by 79% and 30%, respectively, the risks of cardiovascular thromboembolic events (RR = 1.79, 95% CI 1.33-2.41; P = 0.0001) and renal impairment/hypertension (RR = 1.30, 95% CI 1.09-1.54; P = 0.003) caused by coxib use alone. CONCLUSION Coxibs may reduce the overall risk of colorectal neoplasms, but the chemopreventive effects are attenuated over time. When participants take low-dose aspirin simultaneously, coxibs may not be useful for chemoprevention of colorectal neoplasm.

Abstract
BACKGROUND Gram-negative complicated urinary tract infections (cUTIs) can have serious consequences for patients and hospitals. AIM To examine the clinical and economic burden attributable to Gram-negative carbapenem-non-susceptible (C-NS; resistant/intermediate) infections compared with carbapenem-susceptible (C-S) infections in 78 US hospitals. METHODS All non-duplicate C-NS and C-S urine source isolates were analysed. A subset had principal diagnosis ICD-9-CM codes denoting cUTI. Collection time (<3 vs ≥3 days after admission) determined isolate classification as community or hospital onset. Mortality, 30-day re-admissions, length of stay (LOS), hospital cost and net gain/loss in US dollars were determined for C-NS and C-S cases, with the C-NS-attributable burden estimated through propensity score matching. Three subgroups with adequate patient numbers were analysed: cUTI principal diagnosis, community onset; other principal diagnosis, community onset; and other principal diagnosis, hospital onset. FINDINGS The C-NS-attributable mortality risk was significantly higher (58%) for the other principal diagnosis, hospital-onset subgroup alone (odds ratio 1.58, 95% confidence interval 1.14-2.20; P < 0.01). The C-NS-attributable risk for 30-day re-admission ranged from 29% to 55% (all P < 0.05). The average attributable economic impact of C-NS was 1.1-3.9 additional days LOS (all P < 0.05), US$1512-10,403 additional total cost (all P < 0.001) and US$1582-11,848 net loss (all P < 0.01); overall burden and C-NS-attributable burden were greatest in the other principal diagnosis, hospital-onset subgroup. CONCLUSION Greater clinical and economic burden was observed in propensity-score-matched patients with C-NS infections compared with C-S infections, regardless of whether cUTI was the principal diagnosis, and this burden was most severe in hospital-onset infections.

Abstract
AIM The aim was to test the feasibility of a novel three-dimensional (3D) printed guiding device for electrode implantation of sacral neuromodulation (SNM). METHOD A 3D printed guiding device for electrode implantation was customized to patients' anatomy of the sacral region. Liquid photopolymer was selected as the printing material. The details of the device designation and prototype building are described. The guiding device was used in two patients who underwent SNM for intractable constipation. Details of the procedure and the outcomes are given. RESULTS With the help of the device, the test needle for stimulation was placed in the target sacral foramen successfully at the first attempt of puncture in both patients. The time to implant a tined SNM electrode was less than 20 min and no complications were observed. At the end of the screening phase, symptoms of constipation were relieved by more than 50% in both patients and permanent stimulation was established. CONCLUSION The customized 3D printed guiding device for implantation of SNM is a promising instrument that facilitates a precise and quick implantation of the electrode into the target sacral foramen.

Abstract
The purpose of this study was to investigate the functional connectivity (FC) of thalamic subdivisions in patients with juvenile myoclonic epilepsy (JME). Resting state functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) data were acquired from 22 JME and 25 healthy controls. We first divided the thalamus into eight subdivisions by performing independent component analysis on tracking fibers and clustering thalamus-related FC maps. We then analyzed abnormal FC in each subdivision in JME compared with healthy controls, and we investigated their associations with clinical features. Eight thalamic sub-regions identified in the current study showed unbalanced thalamic FC in JME: decreased FC with the superior frontal gyrus and enhanced FC with the supplementary motor area in the posterior thalamus increased thalamic FC with the salience network (SN) and reduced FC with the default mode network (DMN). Abnormalities in thalamo-prefrontocortical networks might be related to the propagation of generalized spikes with frontocentral predominance in JME, and the network connectivity differences with the SN and DMN might be implicated in emotional and cognitive defects in JME. JME was also associated with enhanced FC among thalamic sub-regions and with the basal ganglia and cerebellum, suggesting the regulatory role of subcortical nuclei and the cerebellum on the thalamo-cortical circuit. Additionally, increased FC with the pallidum was positive related with the duration of disease. The present study provides emerging evidence of FC to understand that specific thalamic subdivisions contribute to the abnormalities of thalamic-cortical networks in JME. Moreover, the posterior thalamus could play a crucial role in generalized epileptic activity in JME.

Abstract
BACKGROUND We report the results of International Nosocomial Infection Control Consortium (INICC) surveillance study from January 2010-December 2015 in 703 intensive care units (ICUs) in Latin America, Europe, Eastern Mediterranean, Southeast Asia, and Western Pacific. METHODS During the 6-year study period, using Centers for Disease Control and Prevention National Healthcare Safety Network (CDC-NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 861,284 patients hospitalized in INICC hospital ICUs for an aggregate of 3,506,562 days. RESULTS Although device use in INICC ICUs was similar to that reported from CDC-NHSN ICUs, DA-HAI rates were higher in the INICC ICUs: in the INICC medical-surgical ICUs, the pooled rate of central line-associated bloodstream infection, 4.1 per 1,000 central line-days, was nearly 5-fold higher than the 0.8 per 1,000 central line-days reported from comparable US ICUs, the overall rate of ventilator-associated pneumonia was also higher, 13.1 versus 0.9 per 1,000 ventilator-days, as was the rate of catheter-associated urinary tract infection, 5.07 versus 1.7 per 1,000 catheter-days. From blood cultures samples, frequencies of resistance of Pseudomonas isolates to amikacin (29.87% vs 10%) and to imipenem (44.3% vs 26.1%), and of Klebsiella pneumoniae isolates to ceftazidime (73.2% vs 28.8%) and to imipenem (43.27% vs 12.8%) were also higher in the INICC ICUs compared with CDC-NHSN ICUs. CONCLUSIONS Although DA-HAIs in INICC ICU patients continue to be higher than the rates reported in CDC-NSHN ICUs representing the developed world, we have observed a significant trend toward the reduction of DA-HAI rates in INICC ICUs as shown in each international report. It is INICC's main goal to continue facilitating education, training, and basic and cost-effective tools and resources, such as standardized forms and an online platform, to tackle this problem effectively and systematically.

Cyclin G2 inhibits epithelial-to-mesenchymal transition by disrupting Wnt/β-catenin signaling. Oncogene 2016; 35:4816-27.

Abstract
Epithelial ovarian cancer (EOC) has the highest mortality rate among gynecological malignancies owing to poor screening methods, non-specific symptoms and limited knowledge of the cellular targets that contribute to the disease. Cyclin G2 is an unconventional cyclin that acts to oppose cell cycle progression. Dysregulation of the cyclin G2 gene (CCNG2) in a variety of human cancers has been reported; however, the role of cyclin G2 in tumorigenesis remains unclear. In this study, we investigated the function of cyclin G2 in EOC. In vitro and in vivo studies using several EOC-derived tumor cell lines revealed that cyclin G2 inhibited cell proliferation, migration, invasion and spheroid formation, as well as tumor formation and invasion. By interrogating cDNA microarray data sets, we found that CCGN2 mRNA is reduced in several large cohorts of human ovarian carcinoma when compared with normal ovarian surface epithelium or borderline tumors of the ovary. Mechanistically, cyclin G2 was found to suppress epithelial-to-mesenchymal transition (EMT), as demonstrated by the differential regulation of various EMT genes, such as Snail, Slug, vimentin and E-cadherin. Moreover, cyclin G2 potently suppressed the Wnt/β-catenin signaling pathway by downregulating key Wnt components, namely LRP6, DVL2 and β-catenin, which could be linked to inhibition of EMT. Taken together, our novel findings demonstrate that cyclin G2 has potent tumor-suppressive effects in EOCs by inhibiting EMT through attenuating Wnt/β-catenin signaling.

Abstract
This study aimed to evaluate the effects of feeding glycerol-enriched yeast culture (GY) on feed intake, lactation performance, blood metabolites, and expression of some key hepatic gluconeogenic enzymes in dairy cows during the transition period. Forty-four multiparous transition Holstein cows were blocked by parity, previous 305-d mature equivalent milk yield, and expected calving date and randomly allocated to 4 dietary treatments: Control (no additive), 2 L/d of GY (75.8 g/L glycerol and 15.3 g/L yeast), 150 g/d of glycerol (G; 0.998 g/g glycerol), and 1 L/d of yeast culture (Y; 31.1 g/L yeast). All additives were top-dressed and hand mixed into the upper one-third of the total mixed ration in the morning from -14 to +28 d relative to calving. Results indicated that the DMI, NE intake, change of BCS, and milk yields were not affected by the treatments ( > 0.05). Supplementation of GY or Y increased milk fat percentages, milk protein percentages, and milk protein yields relative to the Control or G group ( < 0.05). Cows fed GY or G had higher glucose levels and lower β-hydroxybutyric acid (BHBA) and NEFA levels in plasma than cows fed the Control ( < 0.05) and had lower NEFA levels than cows fed Y ( < 0.05). On 14 d postpartum, cows fed GY or G had higher enzyme activities, mRNA, and protein expression of cytosolic phosphoenolpyruvate carboxykinase (PEPCK-C; < 0.05); higher enzyme activities ( < 0.05) and a tendency toward higher mRNA expression ( < 0.10) of glycerol kinase (GK); and a tendency toward higher enzyme activities of pyruvate carboxylase (PC) in the liver ( < 0.10) when compared with cows fed Control or Y. The enzyme activities, mRNA, and protein expression of PEPCK-C, PC, and GK did not differ between cows fed GY and G ( > 0.10). In conclusion, dietary GY or Y supplementation increased the milk fat and protein content of the cows in early lactation and GY or G supplementation improved the energy status as indicated by greater plasma glucose and lower plasma BHBA and NEFA concentrations and upregulated the hepatic gluconeogenic enzymes of dairy cows during the transition period. Feeding cows with a GY mixture in the peripartum period combined the effects of yeast on lactation performance and the effects of glycerol on energy status in dairy cows.

Role of thalamic nuclei in the modulation of Fos expression within the cerebral cortex during hypertonic saline-induced muscle nociception. Neuroscience 2015; 304:36-46.

Abstract
It has been proposed that thalamic mediodorsal (MD) and ventromedial (VM) nuclei form thalamic 'nociceptive discriminators' in discrimination of nociceptive afferents, and specifically govern endogenous descending facilitation and inhibition. The present study conducted in rats was to explore the role of thalamic MD and VM nuclei in modulation of cerebral neuronal activities by means of detection of spatiotemporal variations of Fos expression within the cerebral cortex. Following a unilateral intramuscular injection of 5.8% saline into the gastrocnemius muscle, Fos expression within the bilateral, different areas of the cerebral cortex except S2 was significantly increased (P<0.05). Particularly, the increases in Fos expression within the cingulate cortex and the insular cortex occurred at 0.5h, 4h and reached the peak level at 4h, 16h, respectively. Electrolytic lesion of the contralateral thalamic MD and VM nuclei significantly blocked the 5.8% saline intramuscularly induced increases in Fos expression within the bilateral cingulate and insular cortices, respectively. Additionally, the 5.8% saline-induced Fos expression in the cingulate cortex and the insular cortex were dose-dependently attenuated by microinjection of μ-opioid antagonist β-funaltrexamine hydrochloride into the thalamic MD and VM nuclei. It is suggested that (1) the neural circuits of 'thalamic MD nucleus - cingulate cortex' and 'thalamic VM nucleus - insular cortex' form two distinct pathways in the endogenous control of nociception, (2) mirror or contralateral pain is hypothesized to be related to cross-talk of neuronal activities within the bilateral cerebral cortices modulated by μ-opioid receptors within the thalamic MD and VM nuclei.

Abstract
This study was conducted to evaluate the effects of supplemental common yeast culture (CY) and glycerol-enriched yeast culture (GY) on performance, plasma metabolites, antioxidant status, and heat shock protein 70 (HSP70) mRNA expression in lactating Holstein cows under heat stress. During summer months, 30 healthy multiparous lactating cows (parity 3.25 ± 0.48; 60 ± 13 d in milk [DIM]; 648 ± 57 kg BW; an average milk yield of 33.8 ± 1.6 kg/d) were blocked by parity, previous milk yield, and DIM and randomly allocated to 3 dietary treatments: no supplemental yeast culture (Control), 1 L/d of CY (33.1 g yeast) per cow, and 2 L/d of GY (153.2 g glycerol and 31.6 g yeast) per cow. During the 60-d experiment, values of air temperature and relative humidity inside the barn were recorded hourly every 3 d to calculate temperature-humidity index (THI). Weekly rectal temperatures (RT) and respiration rates and daily DMI and milk yield were recorded for all cows. Milk and blood samples were taken twice monthly, and BW and BCS were obtained on d 0 and 60. In this experiment, THI values indicated cows experienced a moderate heat stress. Cows supplemented with CY and GY had greater yields of milk, energy-corrected milk and milk fat, and milk fat percent but lower HSP70 mRNA expression in peripheral blood lymphocytes than Control cows (P < 0.05). Supplementing CY and GY tended (P < 0.15) to decrease RT at 1400 h, increase milk protein yield and erythrocyte glutathione, and reduce plasma urea nitrogen compared with Control. Lower plasma NEFA concentration and HSP70 mRNA expression in peripheral blood lymphocytes (P < 0.05) and tendencies towards greater plasma glucose concentration (P = 0.11) but less BW loss (P = 0.14) were observed in GY relative to CY cows. In conclusion, either CY or GY supplementation partially mitigated the negative effects of heat stress on performance and HSP70 mRNA expression of lactating cows, and GY supplementation provided additional improvements in energy status and HSP70 gene expression of lactating cows.

Abstract
Bladder cancer is a highly heterogeneous neoplasm. We examined the gene expression profile in 3 bladder cancer stages (Ta, T1, T2) using expression microarray analysis of 40 bladder tumors. Differentially expressed genes were found by the t-test, with <0.005 as the significance threshold. KEGG pathway-enrichment analysis was used to study the signaling pathways of the genes. We found 36 genes that could be used as molecular markers for predicting the transition from Ta-T1 to T1-T2. Among these, 11 overlapped between Ta-T1 and T1-T2 stages. Six genes were down-regulated at the Ta-T1 stage, but were up-regulated at the T1-T2 stage (ANXA5, ATP6V1B2, CTGF, GEM, IL13RA1, and LCP1); 5 genes were up-regulated at the Ta-T1 stage, but down-regulated at the T1-T2 stage (ACPP, GNL1, RIPK1, RAPGEF3, and ZER1). Another 25 genes changed relative expression levels at the T1-T2 stage. These genes (including COL1A1, COL1A2, FN1, ITGA5, LGALS1, SPP1, VIM, POSTN, and COL18A1) may be involved in bladder cancer progression by affecting extracellular matrix-receptor interaction and focal adhesion. The cytokine-cytokine receptor interaction, neuroactive ligand-receptor interaction, and calcium-signaling pathway were associated with bladder cancer progression at both the Ta-T1 and T1-T2 stages.

Abstract
BACKGROUND Intrathecal administration of antibiotics has potentially high effectiveness for the treatment for severe intracranial infections, particularly nosocomial meningitis. The use of intrathecal injection of antibiotics has been reported mostly in case reports. However, there is sparse data regarding the pharmacokinetics of antibiotics after intrathecal administration. AIM This study investigated whether intrathecal injection is an effective method for the administration of imipenem. MATERIALS AND METHODS The pharmacokinetics of imipenem after intrathecal and intravenous administration of 1:1 imipenem: cilastatin (IMI/CIL) to rabbits were compared. RESULTS The AUC0-t in the cerebrospinal fluid for intrathecal administration was approximately twice that of an equal dose of intravenous administration at doses of 0.35, 0.7, and 1.4 mg/kg. Brain concentrations of imipenem after intrathecal injection were three times greater than observed after intravenous injection and remained high for at least 8 hours post-injection. Elimination of imipenem after administration by either route was primarily via urine, but a transient surge of imipenem in bile and intestinal tissue was observed. CONCLUSIONS Results indicate that there is a clinical potential for intrathecally administered IMI/CIL. Further studies are warranted to investigate the potential for seizure and to assess the translatability of the rabbit model to human treatment.

RNAi-mediated knockdown of pituitary tumor- transforming gene-1 (PTTG1) suppresses the proliferation and invasive potential of PC3 human prostate cancer cells. Braz J Med Biol Res 2012; 45:995-1001.

Abstract
Pituitary tumor-transforming gene-1 (PTTG1) is a proto-oncogene that promotes tumorigenesis and metastasis in numerous cell types and is overexpressed in a variety of human tumors. We have demonstrated that PTTG1 expression was up-regulated in both human prostate cancer specimens and prostate cancer cell lines. For a more direct assessment of the function of PTTG1 in prostate tumorigenesis, RNAi-mediated knockdown was used to selectively decrease PTTG1 expression in PC3 human prostate tumor cells. After three weeks of selection, colonies stably transfected with PTTG1-targeted RNAi (the knockdown PC3 cell line) or empty vector (the control PC3 cell line) were selected and expanded to investigate the role of PTTG1 expression in PC3 cell growth and invasion. Cell proliferation rate was significantly slower (28%) in the PTTG1 knockdown line after 6 days of growth as indicated by an MTT cell viability assay (P < 0.05). Similarly, a soft agar colony formation assay revealed significantly fewer (66.7%) PTTG1 knockdown PC3 cell colonies than control colonies after three weeks of growth. In addition, PTTG1 knockdown resulted in cell cycle arrest at G1 as indicated by fluorescence-activated cell sorting. The PTTG1 knockdown PC3 cell line also exhibited significantly reduced migration through Matrigel in a transwell assay of invasive potential, and down-regulation of PTTG1 could lead to increased sensitivity of these prostate cancer cells to a commonly used anticancer drug, taxol. Thus, PTTG1 expression is crucial for PC3 cell proliferation and invasion, and could be a promising new target for prostate cancer therapy.

Abstract
Genetic map construction and identification of quantitative trait loci (QTLs) for blackleg resistance were performed for four mapping populations derived from five different canola source cultivars. Three of the populations were generated from crosses between single genotypes from the blackleg-resistant cultivars Caiman, Camberra and (AV)Sapphire and the blackleg-susceptible cultivar Westar(10). The fourth population was derived from a cross between genotypes from two blackleg resistant varieties (Rainbow and (AV)Sapphire). Different types of DNA-based markers were designed and characterised from a collection of 20,000 EST sequences generated from multiple Brassica species, including a new set of 445 EST-SSR markers of high value to the international community. Multiple molecular genetic marker systems were used to construct linkage maps with locus numbers varying between 219 and 468, and coverage ranging from 1173 to 1800 cM. The proportion of polymorphic markers assigned to map locations varied from 70 to 89% across the four populations. Publicly available simple sequence repeat markers were used to assign linkage groups to reference nomenclature, and a sub-set of mapped markers were also screened on the Tapidor x Ningyou (T x N) reference population to assist this process. QTL analysis was performed based on percentage survival at low and high disease pressure sites. Multiple QTLs were identified across the four mapping populations, accounting for 13-33% of phenotypic variance (V (p)). QTL-linked marker data are suitable for implementation in breeding for disease resistance in Australian canola cultivars. However, the likelihood of shifts in pathogen race structure across different geographical locations may have implications for the long-term durability of such associations.
