Abstract

Experiments were carried out to shorten the service period and increase the conception rate in 304 cows under productional conditions with the use of drugs, hormonal means, and preparations producing unspecific effects on the reticulo-endothelial system, immediately after giving birth. It was found that: the parenteral treatment of cows one to three hours following calving with 200,000 IU vitestrol and 15-20 IU hypophysin, on the one hand, and (after the removal of the placenta) the infusion into the uterus of 1-2 g chloramphenicol, 15 g ac. citricum of Na citricum and 0.2 g pilocarpinum hydrochloricum, emulsified in 20-30 cu. cm oil emulsion of vitamins A, D3 and E, and the injection by the fifth day after calving of 30-40 cu. cm of tissue emulsion prepared after Filatov with the use of bovine liver or swine embryos, on the other, decreased the "independences" period with 7.01 days, the service period -- with 27.50 days, and the index of insemination -- with 0.60. At the same time the conception rate resulting from the first insemination rose by 25.20 per cent as compared to the untreated animals. The prophylactic veterinary treatment of cows thus contributed in decreasing the cases of retentio secundinarum after calving by 6....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.
