Abstract
BACKGROUND: Bicyclol was used for treating idiosyncratic acute drug-induced liver injury (DILI) in a phase II trial. This study was aimed at evaluating the efficacy and safety of bicyclol 25 and 50 mg thrice a day (TID) for treating acute DILI caused by anti-TB drugs in the light of the trial results.METHODS: We analysed clinical data of patients with TB drug-induced DILI in the trial database. The primary endpoint was reduction in serum alanine aminotransferase (ALT) levels after 4 weeks of treatment compared to baseline.RESULTS: Overall, 148 patients were included, with respectively 48, 52 and 48 patients included in the control (456 mg polyene phosphatidylcholine TID), high-dose (50 mg bicyclol TID) and low-dose (25 mg bicyclol TID) groups. ALT levels decreased by respectively â-"149.0 (IQR â-"299.3 to â-"98.3 (), â-"225.5 (IQR â-"309.3 to â-"181.8 ) and â-"242.5 (IQR â-"364.8 to â-"153.8) U/L in the control, high-dose and low-dose groups (P < 0.001). The ALT normalisation rates at weeks 1, 2, 4, 6 and 8 were higher in the high- and low-dose groups, while adverse events and serious adverse events were similar across groups.CONCLUSIONS: Bicyclol (25 and 50 mg TID) is effective and safe in treating anti-TB DILI, and bicyclol 50 mg TID showed higher efficacy.

Abstract
OBJECTIVES Anaemia during pregnancy is a significant public health problem that adversely impacts both the mother and foetus. However, the factors influencing maternal anaemia in deprived areas of Northwestern China have not yet been thoroughly investigated. This study aimed to describe the prevalence and potential influencing factors of anaemia among expectant mothers in rural areas of Northwestern China. STUDY DESIGN This was a cross-sectional survey. METHODS A cross-sectional survey of 586 expectant mothers was conducted to investigate the prevalence of anaemia, prenatal healthcare coverage, dietary diversity and nutrient supplementation intake. The study population was selected from the sample areas using a random sampling method. Data were collected through a questionnaire, and haemoglobin concentrations were measured by a capillary blood test. RESULTS The results show that 34.8% of the study population were anaemic, with 13% having moderate-to-severe anaemia. The results of the regression analysis showed that diet was not significantly associated with haemoglobin concentrations or the prevalence of anaemia. However, regular prenatal healthcare attendance was found to be an important influencing factor for both haemoglobin concentration (β = 3.67, P = 0.002) and the prevalence of anaemia (odds ratio = 0.59, P = 0.011). CONCLUSIONS Pregnant women receiving regular prenatal care were less likely to be anaemic; thus, it is essential to implement strategies to improve attendance at maternal public health services to reduce the prevalence of maternal anaemia.

Abstract
This experiment evaluated the standard ileal digestibility (SID) of amino acids (AA) in 8 different sources of wheat fed to broilers and established prediction equations based on the chemical properties of wheat. A total of five hundred forty 1-day-old broilers were tested in 2 stages (from d 10 to 13 and from d 25 to 28). On d 13, 324 broilers were randomly assigned to 9 diets (6 replicate cages, 6 broilers per cage); on d 28, 216 broilers were randomly assigned to 9 diets (6 replicate cages, 4 broilers per cage). The 9 experimental diets included 8 test diets and 1 nitrogen-free diet. Titanium dioxide was added as an exogenous indicator at 0.5% of the diet. In 8 wheat samples, the mean values of total amino acids (TAA), dispensable amino acids (DAA), and indispensable amino acids (IAA) were 12.16% (CV 13.70%), 7.97% (CV 15.49%), and 4.20% (CV 11.47%). On d 13, the lowest SID of AA was Lys (86.71%), and the highest was Pro (97.98%). On d 28, the lowest SID of AA was His (81.31%), and the highest was Pro (96.83%). There was an effect of wheat source on the SID of AA except for Trp (P < 0.05); the broiler age had an effect on the SID of AA except for Tyr (P < 0.05); the SID of most AA were higher at d 13 compared to d 28. At d 13, the SID of AA was correlated with CP, NDF, and ST (P < 0.05). At d 28, the SID of AA was correlated with EE, Ash, ADF, and NDF (P < 0.05). The R2 value of stepwise regression equations to predict the SID of AA at d 13 was highest for Leu (R2 = 0.972), lowest for Asp (R2 = 0.785); at d 28 was highest for Gly (R2 = 0.995), lowest for His (R2 = 0.678). In conclusion, this experiment showed that the chemical properties of wheat can be used to establish accurate equations for predicting the SID of AA. This made it more efficient to obtain the SID of AA for wheat.

Abstract
Background: Colorectal cancer (CRC) is a harmful cancer with high morbidity and poor prognosis. There is growing evidence that RNA methylation is closely related to the occurrence of cancer and its malignant biological behavior. N6-methyladenosine (m6A) methylation is the most common RNA modification in eukaryotes, and its multiple regulatory mechanisms in CRC have been elucidated from multiple perspectives. At the same time, the role of 5-methylcytosine (m5C), another important and widely distributed methylation modification, in CRC is far from being elucidated. Methods: In this study, we used RNA immunoprecipitation sequencing combined with bioinformatics methods to identify the m5C peaks on messenger RNA (mRNA) in HCT15 cells and sh-NSUN2 HCT15 cells, understand which transcripts are modified by m5C, and characterize the distribution of m5C modifications. In addition, we performed further bioinformatics analysis of the detected data to initially clarify the potential function of these m5C-modified transcripts. Results: We found significant differences in the distribution of m5C between HCT15 cells and sh-NSUN2 HCT15 cells, suggesting that m5C is likely to play a key role in the occurrence and development of CRC. Furthermore, Gene Ontology (GO) enrichment analysis showed that genes altered by m5C were mainly enriched in phylogeny, synaptic membrane, and transcription factor binding. The Kyoto Encyclopedia of Genes and Genomes (KEGG)pathway analysis showed that the genes altered by m5C are enriched in ECM receptor interaction pathway, the circadian pathway, and the cAMP signaling pathway. Conclusion: Here, our study preliminarily revealed the different distribution patterns of m5C between HCT15 cell and sh-NSUN2 HCT15 cell. Our results open a new window to understand the role of m5C RNA methylation of mRNA in the development of CRC.

Abstract
INTRODUCTION Prenatal and postpartum depression are important public health challenges because of their long-term adverse impacts on maternal and neonatal health. This study investigated the risk of maternal depression among pregnant and postpartum women in poor rural China, along with the correlation between primary family caregiver identity and maternal depression risk. METHODS Pregnant women and new mothers were randomly selected from poor rural villages in the Qinba Mountains area in Shaanxi. Basic demographic information was collected regarding the women and their primary family caregivers. The Edinburgh Postnatal Depression Scale was used to identify women at risk of depression, and the Perceived Social Support Scale was used to evaluate perceived family support. RESULTS This study included 220 pregnant women and 473 new mothers. The mean proportions of women at risk of prenatal and postpartum depression were 19.5% and 18.6%, respectively. Regression analysis showed that identification of the baby's grandmother as the primary family caregiver was negatively correlated with maternal depression risk (β=-0.979, 95% confidence interval [CI]=-1.946 to -0.012, P=0.047). However, the husband's involvement in that role was not significantly correlated with maternal depression risk (β=-0.499, 95% CI=-1.579 to 0.581, P=0.363). Identification of the baby's grandmother as the primary family caregiver was positively correlated with family support score (β=0.967, 95% CI=-0.062 to 1.996, P=0.065). CONCLUSION Prenatal and postpartum depression are prevalent in poor rural China. The involvement of the baby's grandmother as the primary family caregiver may reduce maternal depression risk, but the husband's involvement in that role has no effect.

Abstract
OBJECTIVES The aim of this study was to examine the association of household debt and depressive mood among Chinese adults and to evaluate whether the association varies across types of debt. STUDY DESIGN This is a secondary data analysis of a nationally representative survey. METHODS A prospective cohort study of participants was drawn from the China Family Panel Studies (CFPS). In total, 5135 participants had their depressive mood measured in the CFPS starting from 2014 to 2016 and had participated in the biennial survey. We used logistic regression models to identify predictors of depressive mood with debts, sociodemographic factors, health status factors and health behaviors factors. Adjusted for all measured covariates, we conducted an independent analysis for the experience of housing loans from formal institutions (HLFI), other loans from formal institutions (OLFI), housing loans from relatives and friends (HLRF) and other loans from relatives and friends (OLRF). RESULTS Multiple logistic regression analyses revealed that household debt was a significant risk factor for depressive mood (1.35; 95% confidence interval [CI], 1.19-1.54), after controlling for potential confounders. Independent analysis revealed that HLFI was not a significant predictor, while HLRF (1.26; 95% CI, 1.08-1.48), OLFI (1.45; 95% CI, 1.13-1.87) and OLRF (1.23; 95% CI, 1.02-1.47) remained significant risk factors. CONCLUSION OLFI, HLRF and OLRF were associated with depressive mood, while HLFI was not. To address the problem of individual depressive mood, its apparent association with household debt should be paid more attention.

Abstract
Citrus flavanoids intake can reduce the risk of cardiovascular diseases. Naringenin, a natural predominant flavonoid abundant in citrus fruits, possesses protective effects against atherothrombotic diseases. As platelet activation plays central roles in atherothrombogenesis, we studied the effects of naringenin on platelet activation, signaling, thrombosis and hemostasis. Naringenin dose-dependently inhibited agonist-induced platelet aggregation in vitro, and exhibited more-potent efficacy on ADP-induced platelet aggregation. It also suppressed platelet aggregation stimulated by ADP ex vivo. Naringenin inhibited ADP-induced platelet α-granule secretion, fibrinogen binding, intracellular calcium mobilization and platelet adhesion on collagen-coated surface. Naringenin also inhibited platelet spreading on fibrinogen and clot retraction, processes mediated by outside-in integrin signaling. Mechanism studies indicated that naringenin suppressed PI3K-mediated signaling and phosphodiesterase activity in platelets, in addition to increasing cGMP levels and VASP phosphorylation at Ser239. Furthermore, naringenin-induced VASP phosphorylation and inhibition of platelet aggregation were reversed by a PKA inhibitor treatment. Interestingly, naringenin inhibited thrombus formation in the (FeCl3)-induced rat carotid arterial thrombus model, but not cause a prolonged bleeding time in mice. This study suggests that naringenin may represent a potential antiplatelet agent targeting PI3K and cyclic nucleotide signaling, with a low bleeding risk.

Abstract
Atmospheric new-particle formation (NPF) affects climate by contributing to a large fraction of the cloud condensation nuclei (CCN). Highly oxygenated organic molecules (HOMs) drive the early particle growth and therefore substantially influence the survival of newly formed particles to CCN. Nitrogen oxide (NOx) is known to suppress the NPF driven by HOMs, but the underlying mechanism remains largely unclear. Here, we examine the response of particle growth to the changes of HOM formation caused by NOx. We show that NOx suppresses particle growth in general, but the suppression is rather nonuniform and size dependent, which can be quantitatively explained by the shifted HOM volatility after adding NOx. By illustrating how NOx affects the early growth of new particles, a critical step of CCN formation, our results help provide a refined assessment of the potential climatic effects caused by the diverse changes of NOx level in forest regions around the globe.

Abstract
BACKGROUND Refractory infectious wounds on renal transplantation (RT) recipients significantly prolong hospital stay, increase medical costs, and threaten allograft survival. Vacuum sealing drainage (VSD) therapy is a new technique for managing wounds based on the principle of application of controlled negative pressure. The aim of this study was to summarize the efficacy and safety of VSD therapy in the management of refractory infectious wounds following RT. MATERIALS AND METHODS This is a retrospective study of a cohort of 661 consecutive patients who received renal transplants over a period of 3 years in which the data were collected and analyzed retrospectively. RESULTS Out of the 661 patients, 16 (2.4%) developed refractory wound infection following RT. Nineteen organisms were identified by culture from all patients, including 10 patients infected with 1 or more bacteria, 2 patients with fungal infection, and 4 patients with both. Specifically, mucormycosis was demonstrated in 4 patients, pan-resistant Klebsiella pneumoniae in 2 patients, and Acinetobacter baumannii in 2 patients. All 16 patients were treated with VSD therapy for a median of 37 days (range, 6-111 days). The number of VSD sets used ranged from 4 to 28 sets (mean, 11.1 sets). A combination of antibiotics, debridement, and VSD therapy lead to 100% (16 of 16) wound healing. No VSD-relevant adverse events were observed. CONCLUSIONS VSD therapy is an effective and safe adjunct to conventional treatment modalities for the management of refractory wound infection following RT.

Abstract
Ruddlesden–Popper halide perovskites are 2D solution-processed quantum wells with a general formula A2A’n-1MnX3n+1, where optoelectronic properties can be tuned by varying the perovskite layer thickness (n-value), and have recently emerged as efficient semiconductors with technologically relevant stability. However, fundamental questions concerning the nature of optical resonances (excitons or free carriers) and the exciton reduced mass, and their scaling with quantum well thickness, which are critical for designing efficient optoelectronic devices, remain unresolved. Here, using optical spectroscopy and 60-Tesla magneto-absorption supported by modeling, we unambiguously demonstrate that the optical resonances arise from tightly bound excitons with both exciton reduced masses and binding energies decreasing, respectively, from 0.221 m0 to 0.186 m0 and from 470 meV to 125 meV with increasing thickness from n equals 1 to 5. Based on this study we propose a general scaling law to determine the binding energy of excitons in perovskite quantum wells of any layer thickness. Hybrid 2D layered perovskites are solution-processed quantum wells whose optoelectronic properties are tunable by varying the thickness of the inorganic slab. Here Blancon et al. work out a general behavior for dependence of the excitonic properties in layered 2D perovskites.

Abstract
BACKGROUND This meta-analysis investigates the associations of angiotensin-converting enzyme (ACE) polymorphism and risk of sarcoidosis. MATERIAL AND METHOD Two reviewers independently searched three databases including PubMed, EMBASE, and Cochrane database to identify published studies. Full texts of the selected studies were accessed and related data was extracted using a standardized data extraction form. RESULTS A total of 18 studies contained a total of 1626 patients with sarcoidosis in case group and 2465 healthy controls in control group. Results of the current meta-analysis revealed that ACE DD genotype was associated with a significantly increased risk of sarcoidosis (OR=1.21; 95% CI, 1.06-1.38; I2=48%). In the race subgroup analysis, Asians with ACE DD genotype showed no significant increased risk of sarcoidosis (OR=1.37; 95% CI, 0.94-1.99; I2=78%). Caucasians with ACE DD genotype had an increased sarcoidosis risk (OR=1.16; 95% CI, 1.01-1.36; I2=24%). CONCLUSIONS Our meta-analysis indicated that the ACE DD genotype correlated with an increased risk of sarcoidosis.

Abstract
It is known, for a long time, that angiotensin II (Ang II) could contribute to atherogenesis (AS) and plaque vulnerability, however the underlying mechanisms are poorly understood. Dendritic cells (DCs) are critical for the development of both inflammation and atherogenesis. In the present study, we tried to investigate the influence of AngII on the expression of connexin43 (Cx43) in DCs, as well as the effect of AngII on AS. After mouse bone marrow—derived dendritic cells (BMDCs) were treated by Ang II with or without Valsartan, the expression of Cx43 was quantified by Western Blots. The expression of Cx43 and CD40 (one marker of DCs) of DCs derived from AS plaques of ApoE—/— mice was detected by immunohistochemistry double staining. The morphology of atherosclerotic plaque was indicated by immunohistochemistry staining of smooth muscle cells. The expression of Cx43 (P < 0.05) was increased significantly in mouse BMDCs after treatment with AngII. In atherosclerotic plaques from ApoE—/— mice expressing high levels of endogenous AngII, upregulation of Cx43 (P < 0.01) and CD40 (P < 0.01) was observed. The upregulation and pro—atherogenesis effect of Cx43 could be blocked by the AngII type 1 receptor blocker Valsartan, both in vitro and in vivo. AngII may promote atherosclerosis and plaque vulnerability by increasing the expression of Cx43 in DCs and inducing the maturation of DCs through the angiotensin II type 1 receptor.

Abstract
BACKGROUND Findings regarding the associations between the CC motif chemokine ligand 5 (CCL5) -403G/A and -28C/G polymorphisms and asthma risk are controversial.We performed a meta-analysis to determine whether CCL5 polymorphisms are associated with asthma risk. METHODS We searched the Pubmed, Embase, Chinese National Knowledge Infrastructure (CNKI), and Wanfang databases for studies published before June 2013. The strength of associations was calculated using ORs with 95% CIs. RESULTS Twenty case-control studies were included in this meta-analysis. We did not observe a significant association between the CCL5 -403G/A polymorphism and asthma risk (OR, 1.10; 95% CI, 0.93-1.30; P = .25). The CCL5 - 28C/G polymorphism, however, was associated with a significantly elevated asthma risk (OR, 1.17; 95% CI, 1.02-1.33; P = .02). Subgroup analyses found that the CCL5 -28C/G polymorphism was significantly associated with asthma risk in Asians (OR, 1.16; 95% CI, 1.01-1.33; P = .04) and children (OR, 1.29; 95% CI, 1.03-1.63; P = .03). CONCLUSIONS This meta-analysis suggests that the CCL5 -28C/G polymorphism is a risk factor for asthma.

Abstract
With an increase in mining depth and production, the intensity and frequency of outburst of coal and gas have a tendency to increase. Estimating the intensity of outbursts of coal and gas plays an important role because of its relation with the risk value. In this paper, we described the semiquantitative relations between major parameters and intensity of outburst based on physical experiments. The results showed increment of geostress simulated by horizontal load (from 1.4, 2.4, 3.2, to 3.4 MPa) or vertical load (from 2, 3, 3.6, to 4 MPa) improved the relative intensity rate (3.763-7.403% and 1.273-7.99%); the increment of porosity (from 1.57, 2.51, 3, to 3.6%) improved the relative intensity rate from 3.8 to 13.8%; the increment of gas pressure (from 0, 0.5, 0.65, 0.72, 1, to 1.5 Mpa) induced the relative intensity rate to decrease from 38.22 to 0%; the increment of water content (from 0, 2, 4, to 8%) caused the relative intensity rate to drop from 5.425 to 0.5%. Furthermore, sensitivity and range analysis evaluates coupled factors affecting the relative intensity. In addition, the distinction with initiation of outburst of coal and gas affected by these parameters is discussed by the relative threshold of gas content rate.

Abstract
BACKGROUND Results regarding the association between the interferon-y (lFN-y) +874A/T polymorphism and asthma risk are controversial and ambiguous. The aim of this study was to determine with greater precision the relationship between the IFN-gamma+874A/T polymorphism and asthma using a meta-analysis. METHODS Published literature was retrieved from 5 databases (PubMed, EMBASE, Wanfang, China National Knowledge Infrastructure [CNKI] and Weipu). ORs with 95% Cls were used to assess the strength of association. RESULTS Ten case-control studies involving 697 cases and 1049 controls were identified. In the overall analysis, a significant association between the +874A/T polymorphism and asthma susceptibility was found for AA vs AT + TT (OR, 1.89; 95% CI, 1.37-2.62; P=.0001). In the subgroup analysis by ethnicity, significant associations were found among whites (OR, 1.42; 95% CI, 1.04-1.93; P=.03) and Asians (OR, 2.52; 95% CI, 1.49-4.25; P=.0006). The sensitivity analysis and cumulative meta-analysis further strengthened the validity of this association. No publication bias was observed in this study. CONCLUSION The results of this meta-analysis suggest that the IFN-gamma +874A/T polymorphism is a risk factor for asthma.

Abstract
BACKGROUND Several studies have examined associations between TNF-α polymorphisms and asthma risk, but the results have been conflicting. METHODS A search was performed of the PubMed, EMBASE, and Wanfang databases. Data were extracted and pooled ORs with 95% CIs were calculated. RESULTS Fifty-four studies were included. A significant association between the TNFA-308A/G polymorphism and asthma susceptibility was observed for AA + AG vs GG (OR, 1.39; 95% CI, 1.23-1.58; P < .001). This polymorphism was also significantly associated with asthma risk in whites (OR, 1.47; 95% CI, 1.25-1.73; P < .001), atopic asthma risk (OR, 1.38; 95% CI, 1.16-1.65; P < .001), pediatric asthma risk (OR, 1.48; 95% CI, 1.23-1.79; P < .001), and adult asthma risk (OR, 1.35; 95% CI, 1.21-1.52; P < .001).There was also a significant association between the TNFA -857C/T polymorphism and asthma risk in the recessive model (OR, 1.25; 95% CI, 1.10-1.43; P < .001). In the subgroup analyses, asthma risk was significantly increased in Asians (OR, 1.23; 95% CI, 1.07-1.41; P = .004) and atopic individuals (OR, 1.33; 95% CI, 1.13-1.57; P < .001). No significant association was found for the TNFA-238A/G polymorphism. There were insufficient data to evaluate the associations between TNFA -1031T/C and -863C/A polymorphisms and asthma risk. CONCLUSIONS This meta-analysis suggests that TNFA -308A/G and -857C/T polymorphisms are risk factors for asthma.

Abstract
Xyloglucans (XGs) of Tamarindus indica L. Fabaceae are used as drug vehicles or as ingredients of cosmetics. Two xyloglucans were extracted from T. indica seed with cold water (TSw) and copper complex precipitation (TSc). Both were analyzed in regard to composition and influence on cell viability, proliferation, cell cycle progression, migration, MAPK phosphorylation, and gene expression of human skin keratinocytes (NHEK and HaCaT) and fibroblasts (NHDF) in vitro. TSw and TSc differed in molecular weight, rhamnose content, and ratios of xylose, arabinose, galactose, and glucose. Both XGs improved keratinocytes and fibroblast proliferation, promoted the cell cycle, and stimulated migration and intracellular enzyme activity of NHDF after endosomal uptake. Only TSw significantly enhanced HaCaT migration and extracellular enzyme activity of NHDF and HaCaT. TSw and TSc predominantly enhanced the phosphorylation of molecules that referred to Erk signaling in NHEK. In NHDF parts of the integrin signaling and SAPK/JNK pathway were affected. Independent of cell type TSw marginally regulated the expression of genes, which referred to membrane proteins, cytoskeleton, cytokine signaling, and ECM as well as to processes of metabolism and transcription. Results show that T. indica xyloglucans promote skin regeneration by a direct influence on cell proliferation and migration.

Abstract
1. The aim of the study was to determine if H(2)S is involved in the development of hypoxia-induced pulmonary hypertension in broilers, a condition frequently observed in a variety of cardiac and pulmonary diseases. 2. Two-week-old broilers were reared under normoxic conditions or exposed to normobaric hypoxia (6 h/day) with tissue levels of H(2)S adjusted by administering sodium hydrosulfide (NaHS, 10 µmol/kg body weight/day). Mean pulmonary arterial pressure, right ventricular mass, plasma and tissue H(2)S levels, the expression of cystathionine-β-synthase (CSE) and vascular remodeling were determined at 35 d of age. 3. Exposure to hypoxia-induced pulmonary arterial hypertension was characterized by elevated pulmonary pressure, right ventricular hypertrophy and vascular remodeling. This was accompanied by decreased expression of CSE and decreased concentrations of plasma and tissue H(2)S. 4. Hypoxia-induced pulmonary hypertension was significantly reduced by administration of NaHS but this protective effect was largely abolished by D, L-propargylglycerine, an inhibitor of CSE. 5. The results indicate that H(2)S is involved in the development of hypoxia-induced pulmonary hypertension. Supplementing NaHS or H(2)S could be a strategy for reducing hypoxia-induced hypertension in broilers.

Abstract
Since the first chromosome painting study between human and strepsirrhine primates was performed in 1996, nearly 30 species in Strepsirrhini, Dermoptera and Scandentia have been analyzed by cross-species chromosome painting. Here, the contribution of chromosome painting data to our understanding of primate genome organization, chromosome evolution and the karyotype phylogenetic relationships within strepsirrhine primates, Dermoptera and Scandentia is reviewed. Twenty-six to 43 homologous chromosome segments have been revealed in different species with human chromosome-specific paint probes. Various landmark rearrangements characteristic for each different lineage have been identified, as cytogenetic signatures that potentially unite certain lineages within strepsirrhine primates, Dermoptera and Scandentia.

Abstract
Chromosomal evolution in carnivores has been revisited extensively using cross-species chromosome painting. Painting probes derived from flow-sorted chromosomes of the domestic dog, which has one of the most rearranged karyotypes in mammals and the highest dipoid number (2n=78) in carnivores, are a powerful tool in detecting both evolutionary intra- and inter-chromosomal rearrangements. However, only a few comparative maps have been established between dog and other non-Canidae species. Here, we extended cross-species painting with dog probes to seven more species representing six carnivore families: Eurasian lynx (Lynx lynx), the stone marten (Martes foina), the small Indian civet (Viverricula indica), the Asian palm civet (Paradoxurus hermaphrodites), Javan mongoose (Hepestes javanicas), the raccoon (Procyon lotor) and the giant panda (Ailuropoda melanoleuca). The numbers and positions of intra-chromosomal rearrangements were found to differ among these carnivore species. A comparative map between human and stone marten, and a map among the Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis), stone marten and human were also established to facilitate outgroup comparison and to integrate comparative maps between stone marten and other carnivores with such maps between human and other species. These comparative maps give further insight into genome evolution and karyotype phylogenetic relationships among carnivores, and will facilitate the transfer of gene mapping data from human, domestic dog and cat to other species.

Abstract
Vespertilionidae is the largest chiropteran family that comprises species of different specialization and wide geographic distribution. Up to now, only a few vespertilionid species have been studied by molecular cytogenetic approaches. Here, we have investigated the karyotypic relationships of 4 Vespertilionidae species from Siberia by G-banding and comparative chromosome painting. Painting probes from Aselliscus stoliczkanus were used to establish interspecific homologous chromosomal segments in Myotis dasycneme (2n = 44), Murina hilgendorfi (2n = 44), Plecotus auritus (2n = 32), and Vespertilio murinus (2n = 38). Robertsonian translocations and a few inversions differentiated the karyotypes of the examined species. Painting of P. auritus karyotype with human probes revealed 3 previously undetected cryptic segments homologous to human chromosomes (Homo sapiens, HSA) 8, 15, and 19, respectively. As a consequence, the existence of 2 HSA 4 + 8 syntenies in the P. auritus karyotype has been proven. In addition, a pericentric inversion or centromere shift was revealed on the smallest metacentric P. auritus chromosome 16/17 using the HSA 16 probe explaining the different G-banding pattern in comparison to the homologous Myotis chromosome 16/17.

Abstract
Enterocytozoon bieneusi is clinically the most significant microsporidian parasite associated with persistent diarrhoea, wasting and cholangitis in 30-50% of individuals with HIV/AIDS, as well as in malnutritional children and in the recipients of immunosuppressive therapy. However, the host immune responses to E. bieneusi have not been investigated until recently because of lack of sources of spores, cell culture system and animal models. In this study, we purified spores from heavily infected human or monkey faeces by serial salt-Percoll-sucrose-iodixanol centrifugation, and the purity of spores was confirmed by FACS and scanning electron microscopy. Exposure of dendritic cells to E. bieneusi spores induced the upregulation of the surface markers and production of pro-inflammatory cytokines. The cytokine production was independent of toll-like receptor 4, but MyD88 dependent, because dendritic cells from MyD88 knockout mice failed to secrete these pro-inflammatory cytokines, whereas dendritic cells from C3H/HeJ (a toll-like receptor 4 mutant) were activated by E. bieneusi and secreted these cytokines. Furthermore, MyD88-deficient mice were susceptible to E. bieneusi infection, in contrast to wild-type mice that resisted the infection. Collectively, the data demonstrate innate recognition of E. bieneusi by dendritic cells and the importance of MyD88-dependent signalling in resisting infection in a murine challenge model.

Abstract
Genome-wide homologies between the tsessebe (Damaliscus lunatus, 2n = 36) and Chinese muntjac (Muntiacus reevesi, 2n = 46) have been established by cross-species painting with Chinese muntjac chromosome paints. Twenty-two autosomal painting probes detected 35 orthologous segments in the tsessebe. Hybridization results confirmed that: (i) D. lunatus carries the (9;14) reciprocal translocation that has been proposed to be a derived chromosomal landmark shared by all species of the Antilopinae; (ii) the karyotype of D. lunatus can be derived almost exclusively from the bovid ancestral karyotype through 12 Robertsonian translocations involving 24 ancestral acrocentric autosomes; (iii) in addition to the Rb fusions, pericentric heterochromatic amplification has shaped the morphology of several of the D. lunatus chromosomes. Integrated analysis of these and published cytogenetic data on pecorans has allowed us to accurately discern the karyotype history of Damaliscus (D. lunatus; D. pygargus, 2n = 38; D. hunteri, 2n = 44). The phylogenomic relationships of 3 species reflected by specific chromosomal rearrangements were consistent with published phylogenies based on morphology, suggesting that chromosomal rearrangements have played an important role in speciation within the Alcelaphini, and that karyotype characters are valuable phylogenetic markers in this group.

Abstract
Xenarthra, as the probable earliest offshoot of the placental tree, represents a key taxon for understanding mammalian phylogeny. To gain further insight into the chromosomal evolution and genome organization of the xenarthrans, we have established the first genome-wide comparative chromosome map between human and the 6-banded armadillo (Euphractussexcinctus, 2n = 58), a basal species on the Xenarthra branch, by reciprocal cross-species chromosome painting. In total, 22 human autosomal paints revealed 41 homologous segments in the euchromatic genome of E. sexcinctus. Our results provide further support for the notion that the 2 human homologous segmental associations, i.e. HSA 2/8 and 7a/10p, could constitute the synapomorphies that unite the xenarthrans. Moreover, we propose that the putative ancestral Xenarthra karyotype closely resemble the 2n = 54 karyotype of the E. sexcinctus, consisting of the equivalents of HSA1p, 1q, 2a, 2b, 2c/8c, 3/21, 4a, 4b/8b, 5, 6a, 6b, 7a/10p, 7b/16p, 8a, 9, 10q, 11, 12a/22a, 12b/22b, 13, 14/15, 16q/19q, 17, 18, 19p, 20, and X. In addition, we have analysed the C-banding patterns of E. sexcinctus, and cloned, FISHmapped and sequenced 7 novel repetitive DNA segments, providing further information on the complexity of genome architecture of E. sexcinctus.

Abstract
Comparative genomic data for ochotonids (pikas) are important for understanding the karyotype evolution of lagomorphs. Here, we have established the first genome-wide chromosomal homologies between human and the Forrest's pika (Ochotona forresti, 2n = 54) by cross-species chromosome painting. Integration of our map with the published comparative chromosome map between human and rabbit has enabled the establishment of an indirect homology map between Forrest's pika and domestic rabbit (Oryctolagus cuniculus, 2n = 44), representing the 2 Lagomorpha families: Leporidae and Ochotonidae. Our results demonstrate that (1) most of the proposed ancestral eutherian syntenies or syntenic associations have been retained in the O. forresti genome; (2) the HSA1/10p association, one of the 2 signature rearrangements that were proposed to support the grouping of the orders Lagomorpha and Rodentia into a monophyletic clade called Glires, is also present in the O. forresti genome; and (3) Robertsonian translocations have contributed to the karyotype differences between O. forresti and O. cuniculus.

Abstract
Considering the giraffe (Giraffa camelopardalis, GCA, 2n = 30) as a primitive species, its comparative genomic data are critical for our understanding of the karyotype evolution of pecorans. Here, we have established genome-wide chromosomal homologies between giraffe, Chinese muntjac (Muntiacus reevesi, MRE, 2n = 46) and human (Homo sapiens, HSA, 2n = 46) with whole sets of chromosome-specific paints from Chinese muntjac and human, in addition to providing a high-resolution G-banding karyotype of giraffe. Chinese muntjac and human chromosome paints detected 32 and 45 autosomal homologs in the genome of giraffe, respectively. Our results suggest that it would require at least thirteen fissions, six fusions and three intrachromosomal rearrangements to 'transform' the 2n = 44 eutherian ancestral karyotype to the 2n = 58 pecoran ancestral karyotype. During giraffe evolution, some ancestral eutherian syntenies (i.e. association of HSA3/21, 4/8, 7/16, 14/15, 16/19 and two forms of 12/22) have been retained, while several derived syntenies (i.e. associations of human homologous segments 2/1, 2/9, 5/19, 4/12/22, 8/9, and 10/20) have been produced. The reduction of chromosome number in giraffe from the 2n = 58 pecoran ancestral karyotype could be primarily attributed to extensive Robertsonian translocations of ancestral chromosomal segments. More complex chromosomal rearrangements (including tandem fusion, centromere repositioning and pericentric inversion) have happened during the evolution of GCA2 and GCA8.

Abstract
The Vespertilionidae is the largest family in the order Chiroptera and has a worldwide distribution in the temperate and tropical regions. In order to further clarify the karyotype relationships at the lower taxonomic level in Vespertilionidae, genome-wide comparative maps have been constructed between Myotis myotis (MMY, 2n = 44) and six vesper bats from China: Myotis altarium (MAL, 2n = 44), Hypsugo pulveratus (HPU, 2n = 44), Nyctalus velutinus (NVE, 2n = 36), Tylonycteris robustula (TRO, 2n = 32), Tylonycteris sp. (TSP, 2n = 30)and Miniopterus fuliginosus (MFU, 2n = 46) by cross-species chromosome painting with a set of painting probes derived from flow-sorted chromosomes of Myotis myotis. Each Myotis myotis autosomal probe detected a single homologous chromosomal segment in the genomes of these six vesper bats except for MMY chromosome 3/4 paint which hybridized onto two chromosomes in the genome of M. fuliginosus. Our results show that Robertsonian translocation is the main mode of karyotype evolution in Vespertilionidae and that the addition of heterochromatic material also plays an important role in the karyotypic evolution of the genera Tylonycteris and Nyctalus. Two conserved syntenic associations (MMY9 + 23 and 18 + 19) could be the synapomorphic features for the genus Tylonycteris. The integration of our maps with the published maps has enabled us to deduce chromosomal homologies between human and these six vesper bats and provided new insight into the karyotype evolution of the family Vespertilionidae.

Abstract
The muntjacs (Muntiacus, Cervidae) are famous for their rapid and radical karyotypic diversification via repeated tandem chromosome fusions, constituting a paradigm for the studies of karyotypic evolution. Of the five muntjac species with defined karyotypes, three species (i.e. Muntiacus reevesi, 2n = 46; M. m. vaginalis, 2n = 6/7; and M. crinifrons, 2n = 8/9) have so far been investigated by a combined approach of comparative chromosome banding, chromosome painting and BAC mapping. The results demonstrated that extensive centromere-telomere fusions and a few centric fusions are the chromosomal mechanisms underlying the karyotypic evolution of muntjacs. Here we have applied the same approach to two additional muntjac species with less well-characterized karyotypes, M. feae (2n = 14 male ) and M. gongshanensis (2n = 8 female). High-resolution G-banded karyotypes for M. feae and M. gongshanensis are provided. The integrated analysis of hybridization results led to the establishment of a high-resolution comparative map between M. reevesi, M. feae, and M. gongshanensis, proving that all tandem fusions underpinning the karyotypic evolution of these two muntjac species are also centromere-telomere fusions. Furthermore, the results have improved our understanding of the karyotypic relationships of extant muntjac species and provided compelling cytogenetic evidence that supports the view that M. crinifrons, M. feae, and M. gongshanensis should each be treated as a distinct species.

Abstract
Cross-species chromosome painting has made a great contribution to our understanding of the evolution of karyotypes and genome organizations of mammals. Several recent papers of comparative painting between tree and flying squirrels have shed some light on the evolution of the family Sciuridae and the order Rodentia. In the present study we have extended the comparative painting to the Himalayan marmot (Marmotahimalayana) and the African ground squirrel (Xerus cf. erythropus), i.e. representative species from another important squirrel group--the ground squirrels--, and have established genome-wide comparative chromosome maps between human, eastern gray squirrel, and these two ground squirrels. The results show that 1) the squirrels so far studied all have conserved karyotypes that resemble the ancestral karyotype of the order Rodentia; 2) the African ground squirrels could have retained the ancestral karyotype of the family Sciuridae. Furthermore, we have mapped the evolutionary rearrangements onto a molecular-based consensus phylogenetic tree of the family Sciuridae.
