Abstract

A simple immunological skin test was carried out on 73 weaned piglets at a weight of 15 to 30 kg. Bristles on the piglets' back were shaved off and 0.1-ml amounts of four substances were injected intradermally. These were an isotonic solution of sodium chloride (900 micrograms NaCl in 0.1 ml), histamine (100 mu g in 0.1 mu l), phytohaemagglutinin (200 mu g in 0.1 ml), and a staphylococcus lysate (STAVA). The sites of administration of the substances were 5 cm apart. The dermal reaction was evaluated 20 minutes, 24 and 48 h after the i.d. administration. The size of the papule (measured after 20 min) and the size of the induration (after 24 and 48 h) were measured in two perpendicular directions and the mean value was calculated from the measured data. The average size of the papule was 8.1 mm 20 min after administration of sodium chloride (NaCl) and 19.6 mm 20 min after administration of histamine (HIS). The average size of induration after the administration of phytohaemagglutinin (PHA) was 13.1 mm after 24 h and 11.0 mm after 48 h. The average size of the papule was 11.1 mm 20 min after the administration of STA, the average size of induration was 10.6 mm 24 h after administration of STA and 8.5 mm after 48 h. Piglets that ha...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
