[PMID: 28314875 DOI: 10.1007/s00059-017-4551-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2016] [Revised: 01/06/2017] [Accepted: 02/05/2017] [Indexed: 12/01/2022]
Abstract
BACKGROUND The safety of anticoagulation and radiofrequency catheter ablation (RFCA) in patients with atrial fibrillation (AF) and a history of intracranial hemorrhage (ICH) remains unclear. We investigated the risks and benefits of this approach in AF patients with a history of ICH. PATIENTS AND METHODS The ICH group included 45 AF patients with a history of ICH who underwent RFCA. Five of these patients were excluded because ICH occurred spontaneously after cerebral infarction. The control group included 80 individuals who presented for AF ablation and did not have a history of ICH. Two controls were matched for each study group patient in terms of sex, age (±2 years), type of AF, and procedure date. RESULTS Patients in the ICH group had higher CHADS2 (1.7 ± 1.3 vs. 1.1 ± 1.2, p < 0.05), CHA2DS2-VASc (2.6 ± 1.7 vs. 1.9 ± 1.6, p < 0.05), and HAS-BLED scores (2.5 ± 1.0 vs. 1.1 ± 1.0, p < 0.001). All participants in both groups underwent successful RFCA. The incidence of ICH during follow-up (1 vs. 0, p = 0.333) was similar between the ICH and control groups. AF-free survival between the two groups was not significant (log-rank p = 0.283) within the first 3 months, but was significant (log-rank p = 0.011) within 48 months of RFCA. History of ICH was the only independent predictor of AF recurrence according to univariate Cox regression analysis. CONCLUSION In AF patients with a history of ICH, AF ablation with a standard anticoagulation strategy is safe and does not seem to be associated with an increased risk of hemorrhage.

Abstract
To evaluate the estimation of prevalence ratio (PR) by using bayesian log-binomial regression model and its application, we estimated the PR of medical care-seeking prevalence to caregivers' recognition of risk signs of diarrhea in their infants by using bayesian log-binomial regression model in Openbugs software. The results showed that caregivers' recognition of infant' s risk signs of diarrhea was associated significantly with a 13% increase of medical care-seeking. Meanwhile, we compared the differences in PR's point estimation and its interval estimation of medical care-seeking prevalence to caregivers' recognition of risk signs of diarrhea and convergence of three models (model 1: not adjusting for the covariates; model 2: adjusting for duration of caregivers' education, model 3: adjusting for distance between village and township and child month-age based on model 2) between bayesian log-binomial regression model and conventional log-binomial regression model. The results showed that all three bayesian log-binomial regression models were convergence and the estimated PRs were 1.130(95%CI: 1.005-1.265), 1.128(95%CI: 1.001-1.264) and 1.132(95%CI: 1.004-1.267), respectively. Conventional log-binomial regression model 1 and model 2 were convergence and their PRs were 1.130(95% CI: 1.055-1.206) and 1.126(95% CI: 1.051-1.203), respectively, but the model 3 was misconvergence, so COPY method was used to estimate PR, which was 1.125 (95%CI: 1.051-1.200). In addition, the point estimation and interval estimation of PRs from three bayesian log-binomial regression models differed slightly from those of PRs from conventional log-binomial regression model, but they had a good consistency in estimating PR. Therefore, bayesian log-binomial regression model can effectively estimate PR with less misconvergence and have more advantages in application compared with conventional log-binomial regression model.

Abstract
Peste des petits ruminants viruses (PPRVs) re-emerged in China at the end of 2013 and then spread rapidly into 22 provinces through movement of live goats and sheep. In this study, 96 samples of domestic animals and 13 samples of wildlife were analysed for the presence of PPRV infection by ELISA or RT-PCR. Of 96 samples from sheep and goats, 91 were PPRV positive, whereas all of the 13 samples from three wild species, Capra ibex (Capra ibex sibirica), argali (Ovis ammon) and Goitered gazelle (Gazella subgutturosa), were found to be positive. Five wildlife-origin isolates from the above samples were identified as the lineage IV by a multiple alignment of the partial sequences in N gene.

Abstract
OBJECTIVE To understand the changing trends of immune-related diseases. Disease patterns from both pre-and post-immunization plan and after the immunization program were described, in order to provide evidence for the formulation and revision of immunization program and policy, in Ningxia Hui Autonomous Region. METHODS According to the time order descriptive method was used to analyze and compare the reported data on infectious diseases in Ningxia, between 1958 and 2014. RESULTS From 1958 to 2014, both incidence and mortality of infectious diseases and four diseases related to the immunization programs, in Ningxia appeared significantly low. Since the implementation of the immunization plan, the incidence and mortality of the 4 diseases declined significantly, with the average annual total incidence as 176.12/100 000 before the immunization plan dropped to 2.56/100 000 when the expanded immunization plan was put into practice. The incidence also showed a downward trend. Among diseases that under the immunization program, the incidence of measles appeared the highest, followed by pertussis. However, none of the case on diphtheria or polio appeared which was caused by the wild strains, in 1983 and 1994. CONCLUSION After the implementation of the immunization plan, the immune-related diseases seemed to have been under well controlled. and with remarkable social benefit. Immunization programs appeared the most effective measures to control and eliminate the acute infectious diseases in the region.

Abstract
OBJECTIVES To investigate the cytotoxicity of four dental restorative materials in three-dimensional (3D) L929 cell cultures using a dentin barrier test. METHODS The cytotoxicities of light-cured glass ionomer cement (Vitrebond), total-etching adhesive (GLUMA Bond5), and two self-etching adhesives (GLUMA Self Etch and Single Bond Universal) were evaluated. The permeabilities of human dentin disks with thicknesses of 300, 500, and 1000μm were standardized using a hydraulic device. Test materials and controls were applied to the occlusal side of human dentin disks. The 3D-cell scaffolds were placed beneath the dentin disks. After a 24-h contact with the dentin barrier test device, cell viabilities were measured by performing MTT assays. Statistical analysis was performed using the Mann-Whitney U test. RESULTS The mean (SD) permeabilities of the 300-μm, 500-μm, and 1000-μm dentin disks were 0.626 (0.214), 0.219 (0.0387) and 0.089 (0.028) μlmin-1cm-2cm H2O-1. Vitrebond was severely cytotoxic, reducing the cell viability to 10% (300-μm disk), 17% (500μm), and 18% (1000μm). GLUMA Bond5 reduced the cell viability to 40% (300μm), 83% (500μm), and 86% (1000μm), showing moderate cytotoxicity (300-μm) and non-cytotoxicity (500-μm and 1000-μm). Single Bond Universal and GLUMA Self Etch did not significantly reduce cell viability, regardless of the dentin thicknesses, which characterized them as non-cytotoxic. CONCLUSIONS Cytotoxicity varied with the materials tested and the thicknesses of the dentin disks. CLINICAL SIGNIFICANCE The tested cytotoxicity of materials applied on 300-, 500-, and 1000-μm dentin disks indicates that the clinical use of the test materials (excepting self-etching adhesives) in deep cavities poses a potential risk of damage to the pulp tissues to an extent, depending on the thickness of the remaining dentin.

Abstract
OBJECTIVES Biological age (BA) has been proposed to evaluate the aging status in an objective way instead of chronological age (CA). The purpose of our study is to construct a more precise formula of BA in the cross-sectional study based on a largest-ever sample of our studies. This formula aims at better evaluation of body function and exploring the disciplines of aging in different genders and age stages. METHODS A total of 1,373 healthy Chinese Han (age range, 19-93 years) were recruited from five cities in China, including 581 males and 792 females. Physical examination, blood routine, blood chemistry, and other lab tests were performed to obtain a total of 74 clinical variables. Then, the principal component analysis (PCA) was used to select variables and estimate BA. The BA formula was further validated in a population with some diseases (n=266), including cardiovascular diseases, type 2 diabetes, kidney diseases, pulmonary diseases, cancer and disorders in nervous system. RESULTS The BA formula was constructed as follows: BA = 0.358 (pulse pressure) + 0.258 (trail making test) - 11.552 (mitral valve E/A peak) + 26.383 (minimum intima-media thickness) + 31.965 (Cystatin C) + 0.163 (CA) - 3.902. In validation of the formula, BAs of patients were older than those of healthy persons. The BA accelerates faster in the middle-aged population than in the elderly population (>75 years old). CONCLUSION This BA formula can reflect health condition changes of aging better than CA in a Chinese Han population.

Abstract
AIMS The aim was to investigate the impact of PPARG and APOE gene single nucleotide polymorphisms (SNPs) and additional gene- gene interaction on late-onset Alzheimer's disease (LOAD) risk based on Chinese Han population. METHODS A total of 928 participants (466 males, 462 females), with a mean age of 81.3 ± 16.4 years old, were included in the study, including 460 LOAD patients and 468 normal controls participants. Logistic regression was performed to investigate association between SNP and LOAD risk and generalized multifactor dimensionality reduction (GMDR) was used to analysis the gene-gene interaction. RESULTS Logistic regression analysis showed that LOAD risk was significantly higher in carriers of G allele of the rs405509 polymorphism than those with AA (AG+ GG versus AA, adjusted OR (95%CI) =1.54(1.20-1.89), and higher in carriers of G allele of the rs1805192 polymorphism than those with CC (CG+ GG versus CC, adjusted OR (95%CI) =1.32(1.16-2.43). We also found that there was a potential gene-gene interaction between rs405509 and rs1805192. Participants with AG or GG of rs405509 and CG or GG of rs1805192 genotype have the highest AD risk, compared to participants with AA of rs405509 and CC of rs1805192 genotype, OR (95%CI) was 2.62(1.64 -3.58), after covariates adjustment. CONCLUSIONS G allele of the rs405509 of APOE and G allele of the rs1805192 of PPAR G polymorphism were associated with increased LOAD risk, and participants with AG or GG of rs405509 and CG or GG of rs1805192 genotype have the highest AD risk.

Abstract
Objective: To investigate the features of peripheral nerve injuries in workers exposed to vibration. Methods: A total of 197 male workers [median age: 34 years (21-50 years) ; median working years of vibration exposure: 7.3 years (1-20 years) ] engaged in grinding in an enterprise were enrolled. Their clinical data and electromyography results were analyzed to investigate the features of peripheral nerve impairment. Results: Of all workers, 96 (48.73%) had abnormal electromyography results. Of all workers, 88 (44.7%) had simple mild median nerve injury in the wrist, who accounted for 91.7% (88/96) of all workers with abnormal electromy-ography results. Six workers had ulnar nerve injury, superficial radial nerve injury, or/and superficial peroneal nerve injury and accounted for 6.3% of all workers with abnormal electromyography results. Of all workers, 88 had a reduced amplitude of median nerve sensory transduction, and 28 had slowed median nerve sensory transduction. A total of 46 workers were diagnosed with occupational hand-arm vibration disease and hospitalized for treatment. They were followed up for more than 4 months after leaving their jobs, and most of them showed improvements in neural electromyography results and returned to a normal state. Conclusion: Workers exposed to vibration have a high incidence rate of nerve injury in the hand, mainly sensory function impairment at the distal end of the median nerve, and all injuries are mild peripheral nerve injuries. After leaving the vibration job and being treated, most workers can achieve improvements and return to a normal state.

Abstract
Acori Tatarinowii Rhizoma (ATR), the rhizome of Acorus tatarinowii Schott, is being used clinically to treat neurological disorders. The volatile oil of ATR is being considered as an active ingredient. Here, α-asarone and β-asarone, accounting about 95% of ATR oil, were evaluated for its function in stimulating neurogenesis. In cultured PC12 cells, application of ATR volatile oil, α-asarone or β-asarone, stimulated the expression of neurofilaments, a bio-marker for neurite outgrowth, in a concentration-dependent manner. The co-treatment of ATR volatile oil, α-asarone or β-asarone, with low concentration of nerve growth factor (NGF) potentiated the NGF-induced neuronal differentiation in cultured PC12 cells. In addition, application of protein kinase A inhibitors, H89 and KT5720, in cultures blocked the ATR-induced neurofilament expression, as well as the phosphorylation of cAMP-responsive element binding protein (CREB). In the potentiation of NGF-induced signaling in cultured PC12 cells, α-asarone and β-asarone showed synergistic effects. These results proposed the neurite-promoting asarone, or ATR volatile oil, could be useful in finding potential drugs for treating various neurodegenerative diseases, in which neurotrophin deficiency is normally involved.

Abstract
Stem Leydig cells have been demonstrated to differentiate into adult Leydig cells via intermediate stages of progenitor and immature Leydig cells. However, the exact regulatory mechanisms are unclear. We hypothesized that the development of stem or progenitor Leydig cells depends upon locally produced growth factors. Microarray analysis revealed that the expression levels of activin type I receptor (Acvr1) and activin A receptor type II-like 1 (Acvrl1) were stem > progenitor = immature = adult Leydig cells. This indicates that their ligand activin might play an important role in stem and progenitor Leydig cell proliferation and differentiation. When seminiferous tubules were incubated with 1 or 10 ng/mL activin A for 3 days, it concentration-dependently increased EdU incorporation into stem Leydig cells by up to 20-fold. When progenitor Leydig cells were incubated with 1 or 10 ng/mL activin A for 2 days, it concentration-dependently increased 3 H-thymidine incorporation into progenitor Leydig cells by up to 200%. Real-time PCR analysis showed that activin A primarily increased Pcna expression but reduced Star, Hsd3b1, and Cyp17a1 expression levels. Activin A also significantly inhibited the basal and luteinizing hormone-stimulated androgen production. In conclusion, activin A primarily stimulates the proliferation of stem and progenitor Leydig cells, but inhibits the differentiation of stem and progenitor Leydig cells into the Leydig cell lineage in rat testis.

Abstract
OBJECTIVE To evaluate the efficacy of ultrasound-guided spinal nerve posterior ramus pulsed radiofrequency treatment for lower back post-herpetic neuralgia. MATERIALS AND METHODS 128 cases of lower back or anterior abdominal wall acute post-herpetic neuralgia patients were selected. They were randomly divided into two groups. Group A: oral treatment only with gabapentin + celecoxib + amitriptyline. Group B: while taking these drugs, patients were treated with radiofrequency (RF) pulses using a portable ultrasound device using the paravertebral puncture technique. In both groups, sudden outbreaks of pain were treated with immediate release 10mg morphine tablets. Visual analogue scale (VAS) was used for pain score, Pittsburgh Sleep Quality Index scale (PSQI) was used to evaluate sleep quality and morphine consumption were recorded at different time points, before and after treatment. Treatment efficiency was calculated while the occurrence of complications was documented. RESULTS At each time point after treatment, VAS scores were lower, but scores in the RF group was significantly lower than those of the oral-only group. In terms of sleep quality scores and morphine consumption between the two groups, the RF group was significantly lower than the oral-only group. During the procedure no error occurred with needle penetrating the abdominal cavity, chest, offal or blood vessels. CONCLUSIONS Ultrasound-guided spinal nerve posterior ramus pulsed radiofrequency treatment of lower back or anterior abdominal wall post-herpetic neuralgia proved effective by reducing morphine use in patients and led to fewer adverse reactions.

Abstract
Preheating temperature, maize flour particle size, and levels of water and sulfite were tested during preparation of maize noodles. Heating a mixture of maize flour and water (43-45 % moisture) at 90-95 °C was required to extrude maize noodles using a pasta maker. Maize flour with smaller par ticle size yielded better noodles than did maize meal. Addition of sulfite enabled production of noodles at lower processing temperatures, however, cooking losses increased. Addition of more water yielded noodles that required longer cooking time, but decreased cooking losses. Functionalities of starch and protein in raw ingredients and in products were determined. Starch gelatinized and retrograded during processing of maize extrudates, as indicated by changes in pasting viscosity curves. Above 40 °C, maize proteins increased mixing viscosity of dough. Increased integrity of cooked maize noodles, however, corresponded to increased amounts of gelatinized and retrograded starch.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2016; 23:931-938. [PMID: 27387401 DOI: 10.1016/j.phymed.2016.06.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/16/2015] [Revised: 06/02/2016] [Accepted: 06/08/2016] [Indexed: 06/06/2023]
Abstract
BACKGROUND Pyrrolizidine alkaloids (PAs) are commonly found in many plants including those used in medical therapeutics. The hepatotoxicities of PAs have been demonstrated both in vivo and in vitro; however, the neurotoxicities of PAs are rarely mentioned. PURPOSE In this study, we aimed to investigate in vitro neurotoxicities of clivorine, one of the PAs found in various Ligularia species, in cultured PC12 cells. STUDY DESIGN PC12 cell line was employed to first elucidate the neurotoxicity and the underlying mechanism of clivorine, including cell viability and morphology change, neuronal differentiation marker and signaling pathway. METHODS PC12 cells were challenged with series concentrations of clivorine and/or nerve growth factor (NGF). The cell lysates were collected for MTT assay, trypan blue staining, immunocytofluorescent staining, qRT-PCR and western blotting. RESULTS Clivorine inhibited cell proliferation and neuronal differentiation evidenced by MTT assay and dose-dependently reducing neurite outgrowth, respectively. In addition, clivorine decreased the level of mRNAs encoding for neuronal differentiation markers, e.g. neurofilaments and TrkA (NGF receptor). Furthermore, clivorine reduced the NGF-induced the phosphorylations of TrkA, protein kinase B and cAMP response element-binding protein in cultured PC12 cells. CONCLUSION Taken together, our results suggest that clivorine might possess neurotoxicities in PC12 cells via down-regulating the NGF/TrkA/Akt signaling pathway. PAs not only damage the liver, but also possess neurotoxicities, which could possibly result in brain disorders, such as depression.

Abstract
Background HerboChip is an array of different fractions deriving from herbal extracts. This study aimed to identify effective components from Chinese medicine (CM) that interact with nerve growth factor (NGF) as a target using HerboChip. Methods Fifty types of CM that are traditionally used as remedies for emotion imbalance were selected and extracted with 50 % ethanol. Biotinylated-NGF was hybridized with over 300 chips coated with different HPLC-separated fractions from CM extracts and straptavidin-Cy5 was used to identify the NGF-bound fractions. Results Over 300 chips were screened within a week, and 17 positive hits were identified. The interaction of the identified herbal extracts with NGF was confirmed in cultured PC12 cells. Co-application of NGF and herbal extract interfered with NGF-induced expression of neurofilaments, including NF68 and NF200 in cell cultures. Western blot analysis comparing the intensity of phosphorylated cAMP response element-binding protein (CREB) over total CREB showed NGF-induced CREB phosphorylation was modulated by the identified herbal extracts. Five CM herbs showed activating activities on the NGF response and nine CM herbs showed inhibiting activities. Conclusion The current result supported the applicability of HerboChip for screening NGF binding components from herbal extracts.

Abstract
Warfarin-dosing algorithms combine clinical factors and dosing history with the current international normalized ratio (INR) to estimate the therapeutic warfarin dose. Unfortunately, these approaches can result in an overdose if the INR is spuriously low. Our goal was to develop an alert mechanism based on prior INRs in addition to the current INR. Using data from the Genetics InFormatics Trial (GIFT) of Warfarin to Prevent DVT, we analyzed warfarin dose estimates for days 3 through 11 that were ≥10 % higher than an average of the previous two dose estimates. We fit a stepwise mixed model to current and prior dose estimates, and subsequently compared the root-mean-square-error (RMSE) in predicting the final therapeutic dose using the GIFT algorithm versus the mixed model. From 861 dosing records (obtain from 556 patients), 646 dosing records (75 %) were randomly selected for the derivation cohort and 215 dosing records (25 %) for the validation cohort. Using one prior dose estimate improved the accuracy of the warfarin dose estimate. Compared to a dose estimate based on current INR (GIFT algorithm), the mixed model reduced the RMSE in the derivation cohort by 0.0015 mg/day (RMSE 0.2079 vs. 0.2094; p = 0.039). In the validation cohort, the RMSE reduction was not significant. A mixed model of dose estimates based on the current and most recent INRs shows potential to improve the safety of warfarin dosing. Clinicians should be cautious about aggressively escalating the warfarin dose after an INR that is lower than expected.

Abstract
Thyroid cancer is a very common form of endocrine system malignancy. To date, the molecular mechanism underlying thyroid cancer remains poorly understood. Studies of oncocytic tumors have led to a hypothesis which proposes that defects in oxidative phosphorylation (OX- PHOS) may result in a compensatory increase in mitochondrial replication and gene expression. As a result, mitochondrial DNA (mtDNA) mutation analysis has become a useful tool to explore the molecular basis of this disease. Among these mutations, mitochondrial transfer RNAs (mttRNAs) are the hot spots for pathogenic mutations associated with thyroid cancer. However, due to its high mutation rate, the role of mt-tRNA variants in thyroid cancer is still controversial. To address this problem, in this study, we reassessed seven reported mt-tRNA variants: tRNAAsp G7521A, tRNAArg T10411C and T10463C, tRNALeu(CUN) A12308G, tRNAIle G4292C and C4312T, and tRNAAla T5655C, in clinical manifestations of thyroid cancer. We first performed the phylogenetic conservation analysis for these variants; moreover, we used a bioinformatic tool to compare the minimum free energy (G) of mt-tRNA with and without mutations. Most strikingly, none of these variants caused the significant change of the G between the wild-type and the mutant form, suggesting that they may not play an important roles in thyroid cancer. In addition, we screened the frequency of the “pathogenic” A12308G alternation in 300 patients with thyroid cancer and 200 healthy controls. We found that there were five patients and three control subjects carrying this variant. It seemed that the A12308G variant may be a common polymorphism in the human population. Taken together, our study indicated that variants in mt-tRNA genes may not play active roles in patients with thyroid cancer.

Abstract
In this article we describe a high-precision laboratory measurement targeting the R(6) manifold of the 2ν3 band of 12CH4. Accurate physical models of this absorption spectrum will be required by the Franco-German, Methane Remote Sensing LIDAR (MERLIN) space mission for retrievals of atmospheric methane. The analysis uses the Hartmann-Tran profile for modeling line shape and also includes line-mixing effects. To this end, six high-resolution and high signal-to-noise absorption spectra of air-broadened methane were recorded using a frequency-stabilized cavity ring-down spectroscopy apparatus. Sample conditions corresponded to room temperature and spanned total sample pressures of 40 hPa - 1013 hPa with methane molar fractions between 1 μmol mol-1 and 12 μmol mol-1. All spectroscopic model parameters were simultaneously adjusted in a multispectrum nonlinear least-squares fit to the six measured spectra. Comparison of the fitted model to the measured spectra reveals the ability to calculate the room-temperature, methane absorption coefficient to better than 0.1% at the on-line position of the MERLIN mission. This is the first time that such fidelity has been reached in modeling methane absorption in the investigated spectral region, fulfilling the accuracy requirements of the MERLIN mission. We also found excellent agreement when comparing the present results with measurements obtained over different pressure conditions and using other laboratory techniques. Finally, we also evaluated the impact of these new spectral parameters on atmospheric transmissions spectra calculations.

Abstract
UNLABELLED SIPI-8294, as an erythromycin derivative, has only weak antibacterial effects on MRSA and MSSA. Interestingly, synergistic effect of SIPI-8294 with oxacillin was observed both in vitro and in vivo. Western blot and RT-PCR results demonstrate that mecA expressions were suppressed by SIPI-8294 in MRSA. Furthermore, the knock out of mecA in ATCC 43300 led to the loss of synergy of the combinations while mecA complemented strain showed almost the same synergistic capability compared to the wild type strain. However, the knock out of mecR1 and mecI in MRSA displayed no impact on the synergy of the combinations and the ability of SIPI-8294 to suppress mecA expression. In summary, our study has demonstrated that SIPI-8294 could dramatically reverse MRSA resistance to β-lactams both in vitro and in vivo owing to inhibiting mecA expression. However, mecR1 and mecI, as the pivotal regulatory genes of mecA, do not participate in SIPI-8294-mecA pathway. The research indicates that it may be a promising strategy for combating MRSA infections with the combinations of SIPI-8294 and β-lactam antibiotics. The research of the mechanism is important for structure modification and new drug development. SIGNIFICANCE AND IMPACT OF THE STUDY This study is the first report on the mechanism of synergy between SIPI-8294 and β-lactams against MRSA on the molecular level. In this study, SIPI-8294 showed strong synergistic effects on β-lactam antibiotics both in vitro and in vivo owing to inhibiting mecA expression. As pivotal regulatory genes of mecA, mecR1 and mecI do not participate in SIPI-8294-mecA pathway and are not involved in the synergism of SIPI-8294 and β-lactams. The research indicates that it may be a promising strategy for combating MRSA infections with the combinations of SIPI-8294 and β-lactams. The research is important for structure modification and new drug development.

Abstract
Cardioplegic reperfusion during a long term ischemic period interrupts cardiac
surgery and also increases cellular edema due to repeated solution administration. We
reviewed the clinical experiences on myocardial protection of a single perfusion with
histidine-tryptophan-ketoglutarate (HTK) for high-risk patients with severe pulmonary
arterial hypertension associated with complex congenital heart disease. This
retrospective study included 101 high-risk patients undergoing arterial switch
operation between March 2001 and July 2012. We divided the cohort into two groups:
HTK group, myocardial protection was carried out with one single perfusion with HTK
solution; and St group, myocardial protection with conventional St. Thomas'
crystalloid cardioplegic solution. The duration of cardiopulmonary bypass did not
differ between the two groups. The mortality, morbidity, ICU stay, post-operative
hospitalization time, and number of transfusions in HTK group were lower than those
in St group (P<0.05). Univariate and multivariate analysis showed that HTK is a
statistically significant independent predictor of decreased early mortality and
morbidity (P<0.05). In conclusion, HTK solution seems to be an effective and safe
alternative to St. Thomas' solution for cardioplegic reperfusion in high-risk
patients with complex congenital heart disease.

Abstract
The major objective of this research was to establish the main and interactive effects of corn type and extent of grinding on broiler performance including carcass characteristics. A completely randomized experimental design with a 2 (corn type) × 2 (fine and coarse) factorial arrangement, each with six replicates of 45 male Ross chicks, was applied. Experimental diets, containing dent or hard corn, were formulated with two extents of grinding (3.00 or 6.00 mm screens) for three growing phases. In comparison with dent corn, the hard corn increased body weight (BW) gain and thigh muscle yield (p < 0.05), while decreasing feed conversion ratio (p < 0.01) and abdominal fat deposition (p < 0.05), some aspects of which were age-dependent and appeared to vary with extent of grinding. Coarser grinding increased the weight of proventriculus (p < 0.01), gizzard (p < 0.05) and small + large intestine (p < 0.10) relative to BW, particularly towards market size. These results suggest that feeding hard corn or large-particle-size corn have some favourable effects on growth performance or gastrointestinal development for finishing broilers.

In this study, 108 proteinuric patients who were steroid-resistant were assigned to a sLPD group (0.6 g/kg/d with 0.09 g/kg/d keto acids) or a normal protein diet group (NPD, 1.0 g/kg/d). Estimated dietary protein intake, urinary protein excretion, remission rate, renal function, nutritional status, and blood pressure were measured. RESULTS Baseline characteristics were comparable between the sLPD group (47 patients) and the NPD group (49 patients). Urinary protein excretion significantly decreased in sLPD compared to NPD in months 6, 9, and 12 (P<0.05). Proteinuria reduction was higher in sLPD than in NPD (P<0.001) at the end of the study. Complete remission and partial remission rates were higher in sLPD than in NPD. Serum albumin and pre-albumin levels were higher in sLPD than in NPD in months 9 and 12 (P<0.05). Serum total cholesterol and triglyceride levels declined more significantly in sLPD than in NPD (P<0.01) at the end of the study. There were no differences in nutritional status, renal function, hemoglobin, or blood pressure between the two groups. CONCLUSIONS sLPD is both nutritionally safe and beneficial, providing nephroprotective effects for early-stage CKD patients with steroid-resistant proteinuria.

Abstract
Subarachnoid hemorrhage (SAH) is a devastating disease with high mortality. The mechanisms underlying its pathological complications have not been fully identified. Here, we investigate the potential involvement of the glymphatic system in the neuropathology of SAH. We demonstrate that blood components rapidly enter the paravascular space following SAH and penetrate into the perivascular parenchyma throughout the brain, causing disastrous events such as cerebral vasospasm, delayed cerebral ischemia, microcirculation dysfunction and widespread perivascular neuroinflammation. Clearance of the paravascular pathway with tissue-type plasminogen activator ameliorates the behavioral deficits and alleviates histological injury of SAH. Interestingly, AQP4−/− mice showed no improvements in neurological deficits and neuroinflammation at day 7 after SAH compared with WT control mice. In conclusion, our study proves that the paravascular pathway dynamically mediates the pathological complications following acute SAH independently of glymphatic control.

Abstract
Relative primary acoustic gas thermometry (AGT) determines the ratios of thermodynamic temperatures from measured ratios of acoustic and microwave resonance frequencies in a gas-filled metal cavity on isotherms of interest. When measured in a cavity with known dimensions, the frequencies of acoustic resonances in a gas determine the speed of sound, which is a known function of the thermodynamic temperature T. Changes in the dimensions of the cavity are measured using the frequencies of the cavity's microwave resonances. We explored techniques and materials for AGT at high temperatures using a cylindrical cavity with remote acoustic transducers. We used gas-filled ducts as acoustic waveguides to transmit sound between the cavity at high temperatures and the acoustic transducers at room temperature. We measured non-degenerate acoustic modes in a cylindrical cavity in the range 295 K

Abstract
The expression of acetylcholinesterase (AChE), an enzyme hydrolyzes neurotransmitter acetylcholine at vertebrate neuromuscular junction, is regulated during myogenesis, indicating the significance of muscle intrinsic factors in controlling the enzyme expression. DNA methylation is essential for temporal control of myogenic gene expression during myogenesis; however, its role in AChE regulation is not known. The promoter of vertebrate ACHE gene carries highly conserved CG-rich regions, implying its likeliness to be methylated for epigenetic regulation. A DNA methyltransferase inhibitor, 5-azacytidine (5-Aza), was applied onto C2C12 cells throughout the myotube formation. When DNA methylation was inhibited, the promoter activity, transcript expression and enzymatic activity of AChE were markedly increased after day 3 of differentiation, which indicated the putative role of DNA methylation. By bisulfite pyrosequencing, the overall methylation rate was found to peak at day 3 during C2C12 cell differentiation; a SP1 site located at -1826bp upstream of mouse ACHE gene was revealed to be heavily methylated. The involvement of transcriptional factor SP1 in epigenetic regulation of AChE was illustrated here: (i) the SP1-driven transcriptional activity was increased in 5-Aza-treated C2C12 culture; (ii) the binding of SP1 onto the SP1 site of ACHE gene was fully blocked by the DNA methylation; and (iii) the sequence flanking SP1 sites of ACHE gene was precipitated by chromatin immuno-precipitation assay. The findings suggested the role of DNA methylation on AChE transcriptional regulation and provided insight in elucidating the DNA methylation-mediated regulatory mechanism on AChE expression during muscle differentiation.

Abstract
Photon conversion is exhibited in a borate (LKZBSB) glass system containing Eu(3+), and the enhanced characteristic emissions of Eu(3+) with the codoping of Ce(3+) have been verified. A large Judd-Ofelt intensity parameter Ω2 of Eu(3+) indicates a high asymmetrical and strong covalent environment around rare-earth (RE) ions in LKZBSB glasses and spontaneous emission probability and a maximum emission cross section of the dominant 5D0→7F2 transition were derived to be 370 s(-1) and 1.28×10(-21) cm2, respectively, revealing the potential UV→visible photon-conversion capacity of Eu(3+). Absolutely quantitative evaluation illustrates that Eu(3+) is a favorable photon-conversion center to achieve high photon-conversion efficiency. The addition of Ce(3+) is beneficial to realizing effective red emission of Eu(3+), which possesses commercial value by decreasing the dopant of expensive europium compounds. As an expectation, this photon-conversion LKZBSB glass system can promote the development of a photon downconversion layer for solar cells, which are particularly used in outer space with intense UV radiation.

Abstract
The objective of this study was to explore the linkage of oxidative stress occurring in mitochondria, skeletal muscles, and plasma in heat stress-challenged broilers. At d 35, 24 broilers were randomly assigned to 2 treatments: rearing at high temperature (32 ± 1°C; heat stress group) or normal temperature (21 ± 1.2°C; control) for 7 d. The oxidative damage of lipid, DNA, and protein and the activities of antioxidative enzymes were measured, respectively, in plasma, skeletal muscles (breast and thigh muscles), and skeletal muscle mitochondria. The result showed that heat exposure increased (P < 0.01) plasma concentrations of thiobarbituric acid reacting substances (TBARS) and 8-hydroxydeoxyguanosine (8-OHdG) whereas it deceased total antioxidant capacity (P < 0.05) and ability to inhibit hydroxyl radicals (AIHR; P< 0.001). Protein carbonyl and TBARS levels were increased (P < 0.001) by heat stress in breast and thigh muscles. In skeletal muscle mitochondria, heat stress increased (P < 0.05) 8-OHdG and suppressed AIHR. Plasma activity of superoxide dismutase (SOD) was increased (P< 0.001) whereas glutathione peroxidase (GSH-Px) was suppressed by heat stress (P < 0.001). Heat exposure increased SOD and catalase activities in breast muscle (P < 0.01) but the reverse was true in thigh muscle (P < 0.05). Glutathione peroxidase was increased in thigh muscle (P < 0.001) but was not changed in breast muscle (P > 0.05). Heat stress increased SOD (P < 0.05) and decreased GSH-Px activities (P < 0.05) of mitochondria regardless of muscle types. Plasma allantoin level increased (P < 0.01) correspondingly with urate (P < 0.001) in heat-stressed broilers, indicating that urate could serve as an antioxidant to enhance the antioxidative capacity during stress in a concentration-dependent manner. The activities of respiratory chain complexes I and III were estimated in skeletal muscle mitochondria. Mitochondrial complex I activity was suppressed (P < 0.01) by heat exposure in breast and thigh muscles but complex III activity was elevated only in breast muscle (P < 0.01) of heat-stressed broiler. The fatty acid composition in skeletal muscle was not influenced by heat stress. In conclusion, suppressed mitochondrial complex I activity is associated with oxidative stress induced by heat exposure, which, in turn, is linked with the oxidative damages in muscle tissues and plasma.
