We sequenced and analyzed RNA populations present in mouse and chick during the early stages of embryo...

Authors: Baer A, Fagalde MS, Drake CD, Sohlberg EH, Barash E, Glick S, Millman AJ, Duchin JS Abstract INTRODUCTION: With the goal of eliminating hepatitis C virus (HCV) as a public health problem in Washington State, Public Health-Seattle &King County (PHSKC) designed a Hepatitis C Virus Test and Cure (HCV-TAC) data system to integrate surveillance, clinical, and laboratory data into a comprehensive database. The intent of the system was to promote identification, treatment, and cure of HCV-infected persons (ie, HCV care cascade) using a population health approach. MATERIALS AND METHODS: The data system aut...

Authors: Hallmann-Szelińska E, Łuniewska K, Szymański K, Kowalczyk D, Sałamatin R, Masny A, Brydak LB Abstract The World Health Organization estimates that influenza virus infects 3-5 million people worldwide every year, of whom 290,000 to 650,000 die. In the 2016/2017 epidemic season in Poland, the incidence of influenza was 1,692 per 100,000 population. The influenza A virus, subtype A/H3N2/, was the predominant one in that season. However, in the most recent 2017/2018 epidemic season, the incidence exceeded 1,782 per 100,000 already by August of 2018. In this season, influenza B virus predominated, while the...

In this study, a 3-D S-wave velocity model of the lithosphere in mainland China down to 150 km depth was determined from ambient noise data. First, we collected 2-year continuous waveforms recorded by 1031 broadband stations of the China Regional Seismic Network and NECESSArray. Then, by applying the procedures of noise cross-correlation and time-frequency domain phase-weighted stacking, we obtained the interstation empirical Green's functions of Rayleigh waves. We measured the group and phase velocity dispersions at periods of 5–125 s from the EGFs and inverted both group and phase velocities for the S-wave velo...

In this study, we isolated a wild-type FIPV HRB-17 epidemic strain from the blood sample of household pet cat exhibiting the characteristic wet-form FIP symptoms, which has been confirmed further by animal infection. Further, we developed an EvaGreen-based real-time RT-PCR assay for the accurate detection of FCoV based on the amplification of the highly conserved FIPV N gene. Then, using a combination of the real-time RT-PCR approach and a serum chemistry assay, we performed an epidemiological survey of FIPV infection in cats living in Harbin City, Northeast China. The results indicated that the EvaGreen-based real-time RT...

Authors: Twumasi C, Asiedu L, Nortey ENN Abstract Several mathematical and standard epidemiological models have been proposed in studying infectious disease dynamics. These models help to understand the spread of disease infections. However, most of these models are not able to estimate other relevant disease metrics such as probability of first infection and recovery as well as the expected time to infection and recovery for both susceptible and infected individuals. That is, most of the standard epidemiological models used in estimating transition probabilities (TPs) are not able to generalize the transition esti...

In this study, rfbD gene deleted mutant S19 was developed. The mutant strain designated S19ΔR displayed rough LPS phenotype, which was confirmed by acriflavine dye-agglutination and LPS-SDS-PAGE analysis. The virulence was amply reduced as suggested by increased sensitivity to complement killing; reduction in splenic-bacterial load and the recovery time RT50 as validated in mice model. Anti-brucella humoral response was significantly lower as compared to S19 immunization. The minimal induction of Brucella specific IgG1, IgG2a &IgG2b, and IgG3 resulted in no apparent reactivity to RBPT antigen. S19ΔR showed ...

Publication date: Available online 10 December 2019Source: Carbohydrate PolymersAuthor(s): Dong Huang, Xin Hou, Dawei Zhang, Qian Zhang, Chunyan YanAbstractCibotium barometz, an important traditional Chinese medicine, is used in strengthening bones and tendons. We found that C. barometz crude polysaccharides (CB70) could alleviate bone loss and markedly improve the biomechanical properties of OVX rats. Thus, to clarify biological active ingredient(s) of CB70, two homogeneous polysaccharides (CBP70-1-1 and CBP70-1-2) were purified from CB70. A combination of monosaccharide composition, FT-IR, GC–MS and NMR analysis in...

iang Diao Fowl adenovirus serotype 4 (FAdV-4) is the pathogenic agent of hydropericardium hepatitis syndrome (HHS) in chickens and ducks, which has caused huge economic losses for the Chinese poultry industry since 2015. In order to objectively determine the prevalence and co-infection status of the virus in Shandong province in China, we analyzed a total of 679 clinical cases of chickens and ducks from 36 farms in the province. The results showed that the FAdV-4 infection rate was 65.2% (443/679), and the rate in breeder ducks was almost two-fold higher than that in breeder chickens (68.57% vs. 34.30%). Notably, co-in...
