Identification of circRNA expression signatures correlated with disease severity in pediatric systemic lupus erythematosus.

Background: Systemic lupus erythematosus (SLE) is a complex systemic autoimmune disease with no current cure. Developing diagnostic biomarkers is crucial for improving patient outcomes. Circular RNAs (circRNAs) are a class of noncoding RNAs that are more stable, abundant, and structurally distinct compared to linear RNAs.

Case report: Sideroblastic anemia with B-cell immunodeficiency, periodic fevers, and developmental delay: Three cases and a literature review.

Sideroblastic anemia with B-cell immunodeficiency, periodic fevers, and developmental delay (SIFD) is a serious autosomal recessive syndrome caused by biallelic mutations in cytosine-cytosine-adenosine tRNA nucleotidyltransferase 1 (). The main clinical features of SIFD are periodic fevers, developmental delay, sideroblastic or microcytic anemia, and immunodeficiency. Herein, we report three cases of SIFD with compound heterozygous variants of .

Autoinflammatory mutation in NLRC4 reveals a leucine-rich repeat (LRR)-LRR oligomerization interface.

Background: Monogenic autoinflammatory disorders are characterized by dysregulation of the innate immune system, for example by gain-of-function mutations in inflammasome-forming proteins, such as NOD-like receptor family CARD-containing 4 protein (NLRC4).

Objective: Here we investigate the mechanism by which a novel mutation in the leucine-rich repeat (LRR) domain of NLRC4 (c.G1965C, p.

The effects of booster vaccination on hepatitis B vaccine in anti-HBs negative infants of HBsAg-positive mothers after primary vaccination.

The purpose of this study was to investigate the changes in anti-HBs IgG levels after booster vaccinations in anti-HBs negative infants of HBsAg-positive mothers. After primary vaccination, the immunization effects of different dosages of booster vaccinations of hepatitis B vaccine (CHO) were compared. A group of 472 newborns were vaccinated with three-dose hepatitis B vaccine at birth, 1 mo and 6 mo of age.

The effects of booster vaccination on combined hepatitis A and hepatitis B vaccine in both anti-HBs and anti-HAV negative children 5-15 years after hepatitis B vaccine primary immunization.

In the present study, we investigated the changes in both anti-HAV lgG and anti-HBs lgG levels and compared the antibody seroconversion rates of different doses of combined hepatitis A and hepatitis B vaccine in children. Children who were vaccinated as infants with Hepatitis B vaccine were revaccinated at 5-15 y of age, then the antibody titers were monitored. Among 283 children, this study found that the anti-HAV seroconversion rates (defined as anti-HAV ≥ 1 mIU/ml) after the first and the third dose were 79.

[Detection of co-infection with Lyme spirochetes and Spotted fever group rickettsiae in a group of Haemaphysalis longicornis].

Objective: The present study was conducted to investigate the infection of Lyme disease, Spotted fever, Ehrlichiosis (anaplasmosisin) in wild animals and ticks in the mountain areas of Zhejiang province.

Methods: Nested polymerase chain reaction was used to amplify specific DNA sequences of Lyme spirochetes, Spotted fever group rickettsiae, Ehrlichia(anaplasma) from samples of mice and ticks.

Results: 14 positive samples were identified from 121 mice and 105 groups of ticks.

Occurrence of pandemic clones of Vibrio parahaemolyticus isolates from seafood and clinical samples in a Chinese coastal province.

Fifty-four isolates of Vibrio parahaemolyticus were examined for hemolytic and urease-producing phenotypes as well as presence of virulence markers by polymerase chain reaction (PCR). All clinical isolates (11/11, 100%) and one out of 42 isolates from seafood (2.4%) possessed the tdh gene and showed hemolysis.

Oral administration of submerged cultivated Grifola frondosa enhances phagocytic activity in normal mice.

Grifola frondosa fruiting body (Maitake) has been used as a dietary supplement due to its antitumour and immunomodulatory properties. The aim of this study was to evaluate the immunomodulatory effects of orally administered submerged cultivated G. frondosa mixture, including both mycelium and culture broth, in a healthy murine model.

Immunomodulatory properties of Grifola frondosa in submerged culture.

Maitake (Grifola frondosa) is a popular mushroom in Asia for its tasty flavor and immune-stimulating property. The aim of the study is to investigate the innate immunity augmentation effects of different extracts of mycelia and culture filtrate from G. frondosa in submerged cultures.

Molecular evolution and multilocus sequence typing of 145 strains of SARS-CoV.

In this study, we have identified 876 polymorphism sites in 145 complete or partial genomes of SARS-CoV available in the NCBI GenBank. One hundred and seventy-four of these sites existed in two or more SARS-CoV genome sequences. According to the sequence polymorphism, all SARS-CoVs can be divided into three groups: (I) group 1, animal-origin viruses (such as SARS-CoV SZ1, SZ3, SZ13 and SZ16); (II) group 2, all viruses with clinical origin during first epidemic; and (III) group 3, SARS-CoV GD03T0013.

Molecular biological analysis of genotyping and phylogeny of severe acute respiratory syndrome associated coronavirus.

Background: SARS-CoV is the causative agent of severe acute respiratory syndrome (SARS) which has been associated with outbreaks of SARS in Guangdong, Hong Kong and Beijing of China, and other regions worldwide. SARS-CoV from human has shown some variations but its origin is still unknown. The genotyping and phylogeny of SARS-CoV were analyzed and reported in this paper.

Severe acute respiratory syndrome-associated coronavirus genotype and its characterization.

Objective: To study the severe acute respiratory syndrome (SARS)-associated coronavirus genotype and its characteristics.

Methods: A SARS-associated coronavirus isolate named ZJ01 was obtained from throat swab samples taken from a patient in Hangzhou, Zhejing province. The complete genome sequence of ZJ01 consisted of 29,715 bp (GenBank accession: AY297028, version: gi: 30910859).
