A missense variant in DGKG as a recessive functional variant for hepatic fibrinogen storage disease in Wagyu cattle.

Hepatic fibrinogen storage disease (HFSD) was diagnosed in a 5-month-old Wagyu calf with a history of recurrent respiratory disease. It was characterized by lethargy, dehydration, acidemia, and increased liver enzyme activities. Histologically, disseminated hepatocytes were swollen and showed a single, sharply demarcated, faintly eosinophilic cytoplasmic inclusion with a ground-glass appearance, with the nucleus in an eccentric position.

Human Anti-Lipopolysaccharid (LPS) antibodies against Legionella with high species specificity.

Legionella are Gram-negative bacteria that are ubiquitously present in natural and man-made water reservoirs. When humans inhale aerosolized water contaminated with Legionella, alveolar macrophages can be infected, which may lead to a life-threatening pneumonia called Legionnaires' disease. Due to the universal distribution of Legionella in water and their potential threat to human health, the Legionella concentration in water for human use must be strictly monitored, which is difficult since the standard detection still relies on lengthy cultivation and analysis of bacterial morphology.

LabDisk with complete reagent prestorage for sample-to-answer nucleic acid based detection of respiratory pathogens verified with influenza A H3N2 virus.

Portable point-of-care devices for pathogen detection require easy, minimal and user-friendly handling steps and need to have the same diagnostic performance compared to centralized laboratories. In this work we present a fully automated sample-to-answer detection of influenza A H3N2 virus in a centrifugal LabDisk with complete prestorage of reagents. Thus, the initial supply of the sample remains the only manual handling step.

[A composite polyaniline-containing silica sorbent for DNA isolation].

A composite sorbent based on porous glass beads modified with thin polyaniline coating was prepared by precipitating aniline polymerization in the presence of carrier particles. It was shown that the modification ensures the uniform coating of the inner surface of the carrier pores with the polymer layer approximately 70 A thick. It was shown that the resulting material retains the initial porosity of the carrier and is selective in the separation of nucleic acids and proteins.

A new approach for point mutation detection based on a ligase chain reaction.

A new method for the identification of point mutations is proposed. The method is based on ligase chain reaction (LCR) and it includes a procedure for correction of ligation by Cleavase. Reaction products are detected by a colorimetric method after adsorption of the resulting DNA duplexes to the solid phase.

Molecular cloning of coat protein gene of cucumber mosaic virus, CMV-U strain.

RNA isolation from purified cucumber mosaic virus, CMV-U strain and cDNA synthesis was carried out. The coat protein gene (RNA4) region was amplified selectively by polymerase chain reaction (PCR) with CMV RNA4-specific primers. Double-stranded cDNA was cloned in PRT103 vector at Xho1/Kpn1 site and about 1kb insert obtained.
