Insulin-like growth factor binding protein-2 as a biomarker for lupus nephritis.

Background: Lupus nephritis (LN) is a serious manifestation of systemic lupus erythematosus (SLE). The aim of this study was to identify serum insulin-like growth factor binding protein-2 (IGFBP-2) as a novel non-invasive biomarker for clinical disease and renal pathology in pediatric LN.

Methods: A cross-sectional study on 93 newly diagnosed LN children who were biopsy-proven, 35 SLE children with no renal involvement as disease controls, and 30 healthy controls (HC) with age and gender-matched.

Pathogenic Role and Antibiotic Resistance of Methicillin-Resistant (MRSA) Strains Causing Severe Community-Acquired Pneumonia in Vietnamese Children.

In recent years, the pathogenic role and antibiotic resistance of methicillin-resistant (MRSA) strains causing severe community-acquired pneumonia (CAP) have received increasing attention in clinical practice. The aim of this study was to determine the rate of isolates of MRSA strains causing severe CAP in children and to assess their level of antibiotic resistance. The study design was cross-sectional.

Solution Equilibrium Study of Divalent Metal Ions with Phenylpropanoid Derivatives and Acetylcysteine Ligands.

Solution equilibrium of divalent metal ions (M=Mn, Co, Ni, Cu and Zn) with caffeic acid (ligand C) or dihydrocaffeic acid (ligand D) in binary system, and with acetylcysteine (ligand N) in ternary system were investigated at condition similar to human physiological temperature of 310.15 K and ionic strength of 0.15 mol·dm NaCl.

Seroprevalence of Toxoplasma gondii and Trichinella spiralis infections in wild boars (Sus scrofa) in Korea.

Toxoplasma gondii and Trichinella spiralis are important zoonotic pathogens with worldwide distributions. In Korea, several outbreaks of human toxoplasmosis and trichinellosis due to the consumption of infected wild animals have been reported. The purpose of this study was to determine the seroprevalence of T.

Molecular detection and phylogenetic analysis of Anaplasma bovis from Haemaphysalis longicornis feeding on grazing cattle in Korea.

Ticks are vectors of various pathogens that affect humans and animals throughout the world. Anaplasma bovis is one of the most important tick-borne pathogens that cause cattle diseases but there is still very little information available about this agent in Korea. In the present study, 535 Haemaphysalis longicornis tick pools were analyzed from grazing cattle in five Korean provinces.

Analysis of the complete genome sequence and capsid region of black queen cell viruses from infected honeybees (Apis mellifera) in Korea.

Black queen cell virus (BQCV) infection is one of the most common viral infections in honeybees (Apis mellifera). A phylogenetic tree was constructed for 19 partial nucleotide sequences for the capsid region of South Korean BQCV, which were also compared with 10 previously reported BQCV sequences derived from different countries. The Korean BQCV genomes were highly conserved and showed 97-100% identity.

Phylogenetic analysis of black queen cell virus genotypes in South Korea.

The black queen cell virus (BQCV), a picorna-like honeybee virus, was first isolated from queen larvae and pupae of honeybees found dead in their cells. BQCV is the most common cause of death in queen larvae. Phylogenetic analysis of two Apis cerana and three Apis mellifera BQCV genotypes collected from honeybee colonies in different regions of South Korea, central European BQCV genotypes, and a South African BQCV reference genotype was performed on a partial helicase enzyme coding region (ORF1) and a partial structural polypeptide coding region (ORF2).

Seroprevalence of Toxoplasma gondii and Neospora caninum in dogs from Korea.

Toxoplasma gondii and Neospora caninum are closely related protozoan parasites, they share many common hosts, and can cause neurological diseases in dogs. Dogs can have close contacts with humans and livestock and therefore they can act as reservoirs of these parasites. The aim of this study was to survey the seroprevalence of antibodies against T.

Genetic and phylogenetic analysis of South Korean sacbrood virus isolates from infected honey bees (Apis cerana).

Sacbrood virus (SBV) is one of the most destructive honey bee viruses. The virus causes failure to pupate and death in both larvae and adult bees. Genetic analysis of SBV infected honey bees (Apis cerana) from five different provinces was carried out based on three nucleotide sequences; one partial structural protein coding sequence and two non-structural protein coding sequences.

Genetic analysis of Fasciola isolates from cattle in Korea based on second internal transcribed spacer (ITS-2) sequence of nuclear ribosomal DNA.

Nuclear ribosomal DNA sequence of the second internal transcribed spacer (ITS-2) has been used efficiently to identify the liver fluke species collected from different hosts and various geographic regions. ITS-2 sequences of 19 Fasciola samples collected from Korean native cattle were determined and compared. Sequence comparison including ITS-2 sequences of isolates from this study and reference sequences from Fasciola hepatica and Fasciola gigantica and intermediate Fasciola in Genbank revealed seven identical variable sites of investigated isolates.
