Abstract
We present the precision measurement from May 2011 to May 2017 (79 Bartels rotations) of the proton fluxes at rigidities from 1 to 60 GV and the helium fluxes from 1.9 to 60 GV based on a total of 1×10^{9} events collected with the Alpha Magnetic Spectrometer aboard the International Space Station. This measurement is in solar cycle 24, which has the solar maximum in April 2014. We observed that, below 40 GV, the proton flux and the helium flux show nearly identical fine structures in both time and relative amplitude. The amplitudes of the flux structures decrease with increasing rigidity and vanish above 40 GV. The amplitudes of the structures are reduced during the time period, which started one year after solar maximum, when the proton and helium fluxes steadily increase. Above ∼3 GV the p/He flux ratio is time independent. We observed that below ∼3 GV the ratio has a long-term decrease coinciding with the period during which the fluxes start to rise.

Abstract
Objective: To estimate the incidence and mortality of cervical cancer in China based on the cancer registry data in 2014, collected by the National Central Cancer Registry (NCCR). Methods: There were 449 cancer registries submitted cervical cancer incidence and deaths in 2014 to NCCR. After evaluating the data quality, 339 registries' data were accepted for analysis and stratified by areas (urban/rural) and age group. Combined with data on national population in 2014, the nationwide incidence and mortality of cervical cancer were estimated. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: Qualified 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas). The percentage of morphologically verified cases and death certificate-only cases were 86.07% and 1.01%, respectively. The mortality to incidence ratio was 0.30. The estimates of new cases were about 102 000 in China in 2014, with a crude incidence rate of 15.30/100 000. The age-standardized incidence rates by China standard population (ASR China) and world standard population (ASR world) of cervical cancer were 11.57/100 000 and 10.61/100 000, respectively. Cumulative incidence rate of cervical cancer in China was 1.11%. The crude and ASR China incidence rates in urban areas were 15.27/100 000 and 11.16/100 000, respectively, whereas those were 15.34/100 000 and 12.14/100 000 in rural areas. The estimates of cervical cancer deaths were about 30 400 in China in 2014, with a crude mortality rate of 4.57/100 000. The ASR China and ASR world mortality rates were 3.12/100 000 and 2.98/100 000, respectively, with a cumulative mortality rate (0-74 years old) of 0.33%. The crude and ASR China mortality rates were 4.44/100 000 and 2.92/100 000 in urban areas, respectively, whereas those were 4.72/100 000 and 3.39/100 000 in rural areas. Conclusions: There is still a heavy burden of cervical cancer in China. The burden and patterns of cervical cancer shows different characters of urban and rural people. Prevention and control strategies should be implemented referring to local status.

Abstract
Objective: To estimate the incidence and mortality of female breast cancer in China based on the cancer registration data in 2014, collected by the National Central Cancer Registry (NCCR), and to provide support data for breast cancer prevention and control in China. Methods: There were 449 cancer registries submitting female breast cancer incidence and deaths data occurred in 2014 to NCCR. After evaluating the data quality, 339 registries' data were accepted for analysis and stratified by areas (urban/rural) and age group. Combined with data on national population in 2014, the nationwide incidence and mortality of female breast cancer were estimated. Chinese population census in 2000 and Segi's population were used for age-standardized incidence/mortality rates. Results: Qualified 339 cancer registries covered a total of 288 243 347 populations (144 061 915 in urban and 144 181 432 in rural areas) in 2014. The morphology verified cases (MV%) accounted for 87.42% and 0.59% of incident cases were identified through death certifications only (DCO%), with mortality to incidence ratio of 0.24. The estimates of new breast cancer cases were about 278 900 in China in 2014, accounting for 16.51% of all new cases in female. The crude incidence rate, age-standardized rate of incidence by Chinese standard population (ASRIC), and age-standardized rate of incidence by world standard population (ASRIW) of breast cancer were 41.82/100 000, 30.69/100 000, and 28.77/100 000, respectively, with a cumulative incidence rate (0-74 age years old) of 3.12%. The crude incidence rates and ASRIC in urban areas were 49.94 per 100 000 and 34.85 per 100 000, respectively, whereas those were 31.72 per 100 000 and 24.89 per 100 000 in rural areas. The estimates of breast cancer deaths were about 66 000 in China in 2014, accounting for 7.82% of all the cancer-related deaths in female. The crude mortality rate, age-standardized rate of mortality by Chinese standard population(ASRMC) and age-standardized rate of mortality by world standard population (ASRMW) of breast cancer were 9.90/100 000, 6.53/100 000, and 6.35/100 000, respectively, with a cumulative mortality rate of 0.69%. The crude mortality rates and ASRMC in urban areas were 11.48 per 100 000 and 7.04 per 100 000, respectively, whereas those were 7.93 per 100 000 and 5.79 per 100 000 in rural areas. The incidence and mortality rates of breast cancer were higher in areas than those in rural areas. The age-specific incidence rates of breast cancer increased greatly after 20 years old and peaked at the age group of 55-60. The age-specific mortality rates increased rapidly with age, particularly after 25 years old. They remained at a relative stable level from 55 to 65 years of age, and then increased dramatically and peaked in the age group of 85 and above. Conclusions: Breast cancer is still one of the most common malignant tumor threatening to famale health in China. The disease is more prevalent in urban areas at the age group of 55-60. Comprehensive prevention and control strategies referring to local status and age groups should be carried out to reduce the burden of breast cancer.

Abstract
Objective: The registration data of local cancer registries in 2014 were collected by National Central Cancer Registry (NCCR)in 2017 to estimate the cancer incidence and mortality in China. Methods: The data submitted from 449 registries were checked and evaluated, and the data of 339 registries out of them were qualified and selected for the final analysis. Cancer incidence and mortality were stratified by area, gender, age group and cancer type, and combined with the population data of 2014 to estimate cancer incidence and mortality in China. The age composition of standard population of Chinese census in 2000 and Segi's population were used for age-standardized incidence and mortality in China and worldwide, respectively. Results: Total covered population of 339 cancer registries (129 in urban and 210 in rural) in 2014 were 288 243 347 (144 061 915 in urban and 144 181 432 in rural areas). The mortality verified cases (MV%) were 68.01%. Among them, 2.19% cases were identified through death certifications only (DCO%), and the mortality to incidence ratio was 0.61. There were about 3, 804, 000 new cases diagnosed as malignant cancer and 2, 296, 000 cases dead in 2014 in the whole country. The incidence rate was 278.07/100, 000 (males 301.67/100, 000, females 253.29/100, 000) in China, age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population were 190.63/100, 000 and 186.53/100, 000, respectively, and the cumulative incidence rate (0-74 age years old) was 21.58%. The cancer incidence and ASIRC in urban areas were 302.13/100, 000 and 196.58/100, 000, respectively, whereas in rural areas, those were 248.94/100, 000 and 182.64/100, 000, respectively. The cancer mortality in China was 167.89/100, 000 (207.24/100, 000 in males and 126.54/100, 000 in females), age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population were 106.98/100, 000 and 106.09/100, 000, respectively. And the cumulative incidence rate (0-74 age years old) was 12.00%. The cancer mortality and ASMRC in urban areas were 174.34/100, 000 and 103.49/100, 000, respectively, whereas in rural areas, those were 160.07/100, 000 and 111.57/100, 000, respectively. Lung cancer, gastric cancer, colorectal cancer, liver cancer, female breast cancer, esophageal cancer, thyroid cancer, cervical cancer, encephala and pancreas cancer, were the most common cancers in China, accounting for about 77.00% of the new cancer cases. Lung cancer, liver cancer, gastric cancer, esophageal cancer, colorectal cancer, pancreatic cancer, breast cancer, encephala, leukemia and lymphoma were the leading causes of death and accounted for about 83.36% of cancer deaths. Conclusions: The progression of cancer registry in China develops rapidly in these years, with the coverage of registrations is expanded and the data quality was improved steadily year by year. As the basis of cancer prevention and control program, cancer registry plays an important role in making the medium and long term of anti-cancer strategies in China. As China is still facing the serious cancer burden and the cancer patterns varies differently according to the locations and genders, effective measures and strategies of cancer prevention and control should be implemented based on the practical situation.

Abstract
We report on the observation of new properties of secondary cosmic rays Li, Be, and B measured in the rigidity (momentum per unit charge) range 1.9 GV to 3.3 TV with a total of 5.4×10^{6} nuclei collected by AMS during the first five years of operation aboard the International Space Station. The Li and B fluxes have an identical rigidity dependence above 7 GV and all three fluxes have an identical rigidity dependence above 30 GV with the Li/Be flux ratio of 2.0±0.1. The three fluxes deviate from a single power law above 200 GV in an identical way. This behavior of secondary cosmic rays has also been observed in the AMS measurement of primary cosmic rays He, C, and O but the rigidity dependences of primary cosmic rays and of secondary cosmic rays are distinctly different. In particular, above 200 GV, the secondary cosmic rays harden more than the primary cosmic rays.

Abstract
Objective: Lung cancer incidence and mortality were estimated by sorting and analyzing the national cancer registration data in 2013. Methods: Lung cancer data of 2013 were retrieved from the database of 255 qualified cancer registries. Lung cancer incidence and mortality rates in cancer registration areas in 2013 were estimated by areas (urban/rural), gender and age groups, new lung cancer cases and deaths were estimated using age-specific rates by areas and gender using the corresponding population in 2013. Lung cancer incidence and mortality rates in China in 2013 were calculated based on the estimated new cancer cases and deaths and the corresponding population. The Chinese population in 2000 and Segi's world population were used to calculate age-standardized rates. Results: It was estimated that there were about 732.8 thousand new lung cancer cases and 580.7 thousand deaths occurred in China in 2013. The crude incidence rate was 53.86/10(5)(males 70.10/10(5,) females 36.78/10(5)), while age-standardized incidence rate by Chinese standard populations (ASIRC) and by world standard populations (ASIRW) were 36.19/10(5) and 36.09/10(5) with the cumulative incidence rate (0-74 years old) of 4.42%.The crude mortality rate was 43.41/10(5)(males 57.64/10(5,) females 28.45/10(5)), and age-standardized mortality rate by Chinese standard populations (ASMRC) and by world standard populations (ASMRW) were 28.64/10(5) and 28.41/10(5) with the cumulative incidence rate (0-74 years old) of 3.34%.Both incidence and mortality rates were higher in males than in females. Crude incidence and mortality rates were slightly higher in urban areas than in rural areas, but after age standardized, the results were opposite. Conclusions: Lung cancer is the common cancer, which both incidence and mortality rates are ranking first in China, and the burden of the disease is heavy. Comprehensive measures towards risk factors control, cancer early diagnosis and treatment should be strengthened continuously.

Abstract
OBJECTIVE Incidence data retrieved from population-based cancer registration were used to analyze the esophageal cancer incidence and trend in China. The results can provide basic information for prevention and control of esophageal cancer. METHODS Esophageal cancer incidence data in 2012 were retrieved from the National Central Cancer Registry, nationwide new esophageal cancer cases were estimated using age-specific rate by urban or rural and gender and national population in 2012. Esophageal cancer incidence data from 22 cancer registries were used to analyze the trend during 2000-2011. RESULTS The estimates of new cases of esophageal cancer were about 286.7 thousand in 2012 in China. The incidence rate was 21.17/10(5,) the age-standardized incidence rates by Chinese standard population and by world population were 14.73/10(5) and 14.93/10(5,) respectively, and the cumulative incidence rate was 1.91%.There was a decreasing trend of incidence rate of esophageal cancer in registration areas of China during 2000-2011 with an average annual percentage change (AAPC) of 0.9% (95%CI: -1.6% to -0.1%), no significant differences were observed in urban area and an increasing trend with AAPC of 1.3% (95%CI: 0.2% to 2.5%) in rural area. After age standardization, the incidence rate was significantly decreased, with AAPC of -4.0% (95%CI: -5.5% to -2.6%) overall, -3.8% (95%CI: -4.9% to -2.7%) in urban and -1.7% (95%CI: -3.0% to -0.4%) in rural areas. CONCLUSIONS Esophageal cancer is one of the most common cancers in China and is an emphasis for cancer control. After effective control of risk factors and development of esophageal cancer screening techniques in high-risk areas for years, esophageal cancer incidence appears to have a significant decreasing trend.

Abstract
OBJECTIVE To estimate the nationwide mortality of esophageal cancer in China in 2012, to investigate the trends of the disease, and to provide support data for esophageal cancer prevention and control in China. METHODS Data of population-based cancer registry of China were extracted by sex and geographical area. Joinpoint software was used to analyze the trends of esophageal cancer from 2000 to 2011 using the continuous data of 22 cancer registries. Average annual percentage change rates (AAPC) were calculated, and 17 cancer registries data during 2003-2005 were analyzed. RESULTS In 2012, there were estimated 210.9 thousand new cases of esophageal cancer death in China, with 149 thousand in males and 61.9 thousand in females, accounting for 9.65% of overall cancer death. The crude mortality rate of esophageal cancer in 2012 was 15.58 per 100 000, accounting for the fourth-leading cause of overall cancer deaths. The age-standardized mortality rates by world population and China population were 10.67 per 100 000 and 10.62 per 100 000, respectively. The cumulative mortality rate for age 0-74 was 1.28%. The age-specific mortality rates were increasing with age, and there was a sharp increase after 50 years of age. From 2000 to 2011, there was a slight decreasing trend for crude mortality rate, with the AAPC of -1.1% (95% CI: -1.8% to -0.5%). However, the age standardized mortality rates were decreasing significantly with the AAPC of -4.6% (95% CI: -5.7% to -3.6%). The AAPCs for age-standardized esophageal cancer mortality were -3.8% in urban areas and -2.4% in rural areas. For combined 5-year age standardized relative survival was 20.9% (95%CI: 20.2% to 21.7%) and the 1-, 3- and 5-year observed survival rates were 54.0%, 25.5%, 18.4%, respectively. CONCLUSION There is still a heavy burden of esophageal cancer in China. Prevention and early diagnosis of the disease in esophageal cancer high-risk areas is very essential.

Abstract
Oxaliplatin, a platinum-based chemotherapeutic agent, is an important first-line drug in the treatment of colorectal cancers, but drug resistance causes treatment failure. It has been reported that gap junctional communication can enhance the cytotoxicity of platinum drugs. The gap junction formed of connexin proteins provides a direct pathway for electrical and metabolic cell-cell interaction. The voltage-dependent gating of gap junction allows small hydrophilic molecules and ions to permeate to adjacent cells. Connexin 43 is a diagnostic marker for cancer therapy and the predominant connexin isoform in many cell types. The purpose of this study was to investigate the role of connexin 43 in oxaliplatin activity by using colorectal cancer cell lines. LoVo and HCT116 cell lines were used for analysis. Connexin 43 expression was confirmed by western blot and immunocytochemistry. MTT, western blot, "Parachute" dye-coupling assays and reactive oxygen species measurement were used to detect cytotoxicity and the inhibition of connexin 43 expression induced by oxaliplatin. Results showed that connexin 43 enhanced oxaliplatin cytotoxicity through gap junctional communication function and high concentration of oxaliplatin inhibited connexin 43 expression to counteract its cytotoxicity. This study suggested that connexin 43 could be considered a molecular target of oxaliplatin activity in colorectal cancer.

Abstract
Interleukin-8 (IL-8) is a mediator of inflammation and plays an important role in regulating immune responses. To date, several studies have tested the association between IL-8 gene polymorphisms and development of coronary artery disease (CAD), but their results have proved to be inconsistent. We conducted an investigation to assess the relationship between the IL-8 -251A/T (rs4073) sequence variant and CAD in a Chinese population. Between April 2013 and January 2015, 217 patients with coronary angiography-confirmed CAD were enrolled in our study, along with 245 control subjects. IL-8 -251A/T genotyping was performed using a polymerase chain reaction-restriction fragment length polymorphism assay. A chi-square test revealed that IL-8 -251A/T genotype distributions significantly differed between CAD patients and control subjects (chi-square = 8.29, P < 0.02). Moreover, multiple-logistic regression analysis showed that individuals carrying TA [odds ratio (OR) = 1.59, 95% confidence interval (CI) = 1.01-2.57] and AA (OR = 2.06, 95%CI = 1.21-3.52) genotypes were at increased risk of CAD compared to those with the TT genotype. Under dominant (OR = 1.75, 95%CI = 1.13-2.73) and recessive (OR = 1.54, 95%CI = 1.02-2.37) genetic models, the IL-8 -251A/T polymorphism also significantly correlated with CAD. In conclusion, our results suggest that this variant is an independent risk factor for CAD development under codominant, dominant, and recessive models.

Abstract
Knowledge of the rigidity dependence of the boron to carbon flux ratio (B/C) is important in understanding the propagation of cosmic rays. The precise measurement of the B/C ratio from 1.9 GV to 2.6 TV, based on 2.3 million boron and 8.3 million carbon nuclei collected by AMS during the first 5 years of operation, is presented. The detailed variation with rigidity of the B/C spectral index is reported for the first time. The B/C ratio does not show any significant structures in contrast to many cosmic ray models that require such structures at high rigidities. Remarkably, above 65 GV, the B/C ratio is well described by a single power law R^{Δ} with index Δ=-0.333±0.014(fit)±0.005(syst), in good agreement with the Kolmogorov theory of turbulence which predicts Δ=-1/3 asymptotically.

Abstract
Autophagy can be used as both a protective mechanism of cell survival and a mechanism of cell death.The dual mechanism has been the emphases and difficulties of our research.The latest research shows that autophagy plays an important role in occurrence,development, transfer and treatment of the cancer.Head and neck cancer is usually derived from the upper respiratory tract's. The upper digestive tract's malignant tumor, because of its complex anatomic structure, low 5 years of survival rate, to study the prevention and treatment has the extremely important significance. The purpose of this paper is to clarify the role of lysosome-autophagy,mitochondria-autophagy in the treatment of head and neck cancers and the relationship between autophagy and apoptosis, which will be contribute to the prevention and treatment of head and neck squamous cell carcinomas for us.Autophagy as a cellular lysosomal degradation pathway that can be used as a kind of dynamic monitoring index of the tumor.

Abstract
Objective: To explore the safety and clinical efficacy of partial nephrectomy for solitary kidney tumor. Methods: Twenty patients with a functional or anatomic solitary kidney who underwent nephron-sparing surgery for one or more renal masses were retrospectively analyzed. There were 15 male and 5 female patients with mean age of 63 years.Patients were divided into open partial nephrectomy(OPN) group and laparoscopic partial nephrectomy(LPN) group, the two groups were followed up.Demographic and clinical characteristics were analyzed using student t-test for continuous variables, and the χ2 test for categorical variables. Results: There were 21 tumors whose maximum diameter were 1.5 to 6.0 cm, the mean size was (3.7±1.3)cm, mean operative time was (205.3±81.8)minutes, and median estimated blood loss was 385.6 ml.Five cases accepted blood transfusion intro-operation, 1 case appeared leakage of urine post-operation, none had obvious fever.Eighteen cases were clear cell carcinoma, 2 cases were chromophobe renal carcinoma, 1 case was papillary renal cell carcinoma.Seventeen cases were T1aNxM0, 3 cases were T1bNxM0, 1 case was T3NxM0.One case lost to follow up, the others had completed a mean follow-up of 21.5 months (ranging from 1 to 53 months). One case recurred, no one had metastasis, all patients were alive.The hemoglobin ((114.9±19.6)g/L) and estimated glomerular filtration rate(eGFR) ((46.5±18.2) ml/min) of postoperative day were lesser than pre-operation ((130.7±18.8)g/L, (58.0±16.4) ml/min), while the serum creatinine was higher ((123.8±39.8) μmol/L vs.(90.9±33.2) μmol/L). Three months after operation, hemoglobin, serum creatinine and eGFR had no difference with pre-operative.Compared with OPN group, LPN group gain less blood loss (306 ml vs.510 ml)(t=-2.38, P=0.03), had shorter length of stays (15 d vs.21 d)(t=-3.34, P=0.04), had longer time of renal artery clamping (25.8 min vs.16.5 min)(t=2.60, P=0.02). Conclusions: Partial nephrectomy is secure and effective selection for solitary kidney tumor.The LPN has less trauma, gain less blood loss, recover faster and has shorter length of stays than the OPN, which needs shorter ischaemic time.

Abstract
Piglet diarrhea is one of the most common factors that affects the benefits of the swine industry. Although recent studies have shown that exon 2 of SLA-DQA is associated with piglet resistance to diarrhea, contributions of genetic variation in the additional exon coding regions of this gene remain unclear. Here, we investigated variation in exons 1, 3 and 4 of the SLA-DQA gene and evaluated their effects on diarrheal infection in 425 suckling piglets. No variation was identified in exon 1. In exon 3, there were eight alleles detected, generated by 14 single nucleotide polymorphisms (SNPs) and three nucleotide deletions, eight SNPs being newly identified. Four allele sequences and three SNPs were identified in exon 4, only one SNP being newly identified. Statistical analysis showed that the genotypes of exon 3 are significantly associated with piglet diarrhea; indeed, genotypes DQA*wb01/wb02 and wb04/wb05 are clearly associated with resistance to piglet diarrhea, as they have the lowest probabilities of infection (P < 0.05). However, no significant association was found between the genotypes of exon 4 and diarrhea (P > 0.05). These results provide important new information concerning the level of genetic diversity at the SLA-DQA locus and suggest that further genetic association studies of piglet diarrhea resistance should include analyses of both exons 2 and 3 of this locus.

Abstract
A precision measurement by AMS of the antiproton flux and the antiproton-to-proton flux ratio in primary cosmic rays in the absolute rigidity range from 1 to 450 GV is presented based on 3.49×10^{5} antiproton events and 2.42×10^{9} proton events. The fluxes and flux ratios of charged elementary particles in cosmic rays are also presented. In the absolute rigidity range ∼60 to ∼500 GV, the antiproton p[over ¯], proton p, and positron e^{+} fluxes are found to have nearly identical rigidity dependence and the electron e^{-} flux exhibits a different rigidity dependence. Below 60 GV, the (p[over ¯]/p), (p[over ¯]/e^{+}), and (p/e^{+}) flux ratios each reaches a maximum. From ∼60 to ∼500 GV, the (p[over ¯]/p), (p[over ¯]/e^{+}), and (p/e^{+}) flux ratios show no rigidity dependence. These are new observations of the properties of elementary particles in the cosmos.

Abstract
The purpose of our study was to identify molecular pathways altered during the pathogenesis of hypertrophic cardiomyopathy (HCM) based on data from the STRING protein-protein interaction (PPI) database and the REACTOME pathway database. Identification of differentially expressed genes (DEGs) was carried out, followed by construction of a targeted network and selection of hub genes in this network. PPI pairs in each pathway were extracted, and altered pathways were identified when the said pathway differed from common interactions within the targeted network with a P value of less than 0.05. These altered pathways were further validated based on enrichment of hub genes in pathways within the targeted network. Through this method, we identified 1085 DEGs. The DEGs were inputted into the STRING database, and the resulting targeted network was composed of 3631 interactions. Based on the selection criteria, 30 significantly changed pathways were screened in total. Among these, the top five pathways were found to be involved in immune modulation, signal transduction, hemostasis, and G protein-coupled receptor signaling. Similarly, enrichment in hub gene interactions was also found in members within the altered pathways, including those involved in the innate immune system, the immune system, and signal transduction pathways. These altered pathways are important for understanding the underlying mechanisms of HCM, and can be used for clinical application of treatments in the future.

Abstract
Knowledge of the precise rigidity dependence of the helium flux is important in understanding the origin, acceleration, and propagation of cosmic rays. A precise measurement of the helium flux in primary cosmic rays with rigidity (momentum/charge) from 1.9 GV to 3 TV based on 50 million events is presented and compared to the proton flux. The detailed variation with rigidity of the helium flux spectral index is presented for the first time. The spectral index progressively hardens at rigidities larger than 100 GV. The rigidity dependence of the helium flux spectral index is similar to that of the proton spectral index though the magnitudes are different. Remarkably, the spectral index of the proton to helium flux ratio increases with rigidity up to 45 GV and then becomes constant; the flux ratio above 45 GV is well described by a single power law.

Chlamydia Outer Protein (Cop) B from Chlamydia pneumoniae possesses characteristic features of a type III secretion (T3S) translocator protein. BMC Microbiol 2015; 15:163. [PMID: 26272448 PMCID: PMC4536800 DOI: 10.1186/s12866-015-0498-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2015] [Accepted: 08/03/2015] [Indexed: 01/26/2023] Open
Abstract
Background Chlamydia spp. are believed to use a conserved virulence factor called type III secretion (T3S) to facilitate the delivery of effector proteins from the bacterial pathogen to the host cell. Important early effector proteins of the type III secretion system (T3SS) are a class of proteins called the translocators. The translocator proteins insert into the host cell membrane to form a pore, allowing the injectisome to dock onto the host cell to facilitate translocation of effectors. CopB is a predicted hydrophobic translocator protein within the chlamydial T3SS. Results In this study, we identified a novel interaction between the hydrophobic translocator, CopB, and the putative filament protein, CdsF. Furthermore, we identified a conserved PxLxxP motif in CopB (amino acid residues 166–171), which is required for interaction with its cognate chaperone, LcrH_1. Using a synthetic peptide derived from the chaperone binding motif of CopB, we were able to block the LcrH_1 interaction with either CopB or CopD; this CopB peptide was capable of inhibiting C. pneumoniae infection of HeLa cells at micromolar concentrations. An antibody raised against the N-terminus of CopB was able to inhibit C. pneumoniae infection of HeLa cells. Conclusion The inhibition of the LcrH_1:CopB interaction with a cognate peptide and subsequent inhibition of host cell infection provides strong evidence that T3S is an essential virulence factor for chlamydial infection and pathogenesis. Together, these results support that CopB plays the role of a hydrophobic translocator.

Abstract
The involvement of the cholinergic system in learning and memory in honeybees has been well established using olfactory conditioning. We examined the effect of Methyl Parathion (MeP), an acetylcholinesterase inhibitor of the organo-phosphate family, on the learning and recall of visual and olfactory discrimination tasks in honeybees. One of our expectations was to observe the effects induced by both the nicotinic and muscarinic systems, as the blocking of acetylcholinesterase should induce an increase in the activity of both systems. We were also interested in knowing whether the type of tasks could influence the results. The visual tasks involved learning to discriminate the orientation of gratings in a Y-maze; the olfactory task involved learning to discriminate odours in a proboscis extension reflex (PER) paradigm. The results indicate that MeP treatment enhances recall of learned tasks in the visual and olfactory domains, but it does not affect the acquisition phase in either domain. Surprisingly, MeP treatment led to muscarinic-like effects but failed to mimic the nicotinic-like effects already described in relation to learning phases in honeybees. Implications for the role of cholinergic pathways in learning and memory and the nature of their involvement are discussed, and a hypothesis relating to the organisation of the cholinergic system and the relationship between the nicotinic and muscarinic systems in honeybees is proposed. The results are also discussed in terms of their ecotoxicological consequences.

Abstract
The aim of this study was to determine the percentage of lymphocyte subsets in peripheral blood in patients with active tuberculosis. A total of 21 patients with active tuberculosis and 15 healthy volunteers were included in the study. T-lymphocyte subsets, B-lymphocytes (CD19(+) cells), natural killer (NK) cells and cells positive for costimulatory molecules CD28 and CD152 were evaluated using flow cytometry. Patients with tuberculosis had a significantly decreased percentage of CD3(+) and CD3(+)CD4(+) cells, and a significantly decreased ratio of CD3(+)CD4(+) to CD3(+)CD8(+) cells compared with healthy controls. In contrast, the percentage of B-cells (CD19(+) cells), CD3(+)CD8(+) cells, CD28(+) cells, CD152(+) cells, and subpopulations of CD4(+)CD152(+), CD8(+)CD152(+) and CD8(+)CD28(+) T-cells were all significantly increased compared with healthy controls. There were no statistically significant differences in the percentages of NK cells or CD4(+)CD28(+) cells between patients and controls. These results indicate that patients with active tuberculosis have altered lymphocyte homeostasis.

Abstract
Background: No recent data exist on human papillomavirus (HPV) infection in Beijing, People's Republic of China. Materials and method We interviewed and examined a representative, randomly selected sample of 5552 sexually active women aged 25–54 years. Cervical cell samples were analysed for HPV DNA by a MY09/11-based PCR assay. Results: Human papillomavirus prevalence was 6.7% overall and 4.8% among women without cervical abnormalities. Of the 21 subtypes identified, HPV16 was the commonest type (2.6% overall; 39.1% of HPV-positive women), followed by HPV 58 (1.0%), 33 (0.8%), 43 (0.7%) and 56 (0.7%). High-risk HPV types predominated in all age groups. Human papillomavirus prevalence was highest in young to middle-aged women. Marital status, number of husband's sexual partners, age at sexual debut and nulligravidity were all associated with being HPV positive. Conclusions: In our survey, HPV 16, HPV 58 and HPV 33 were the most prevalent HPV types in Beijing, indicating the potential for the prophylactic HPV 16/18 vaccine in China.

Abstract
Adult mites' bodies of Dermatophagoides farinae were used as antigen in an indirect fluorescent antibody test (IFAT) to detect mite-specific IgG in sera of 48 patients with intestinal acariasis based on stool examination. Antibody titers with positive reaction ranged from 1:4 to 1:512 in 48 patients with intestinal acariasis. If antibody titers > or = 1:16 is regarded as being positive, the positive rate of patients detected with IFAT was 92%.
