Abstract

Studied were 14 batches of ewe milk kashkaval and 13 batches of Vitosha yellow cheese treated with protective antimold agents, such as antiplessin and 'potassium sorbate with movilit'. Kjeldahl's method was employed to determine the total protein, and acid hydrolysis of proteins by means of an automatic amino acid analysis unit HD 1200 ERDG, CSSR to determine the amount of free amino acids. It was found that on the 60th day of the ripening of kashkaval treated with antiplessin the total protein averaged 25.16 per cent; with the use of 'potassium sorbate with movilit' it was 25.39 per cent, on an average. On the 60th day of ripening Vitosha yellow cheese contained 23.97, resp., 23.81 per cent total protein. With the employment of acid hydrolysis is protein in both types of kashkaval the following amino acids were produced: lysine, histidine, arginine, asparagic acid, treonine, serine, glutamic acid, proline, glycine, alanine, valine, methionine, tyrosine, isoleucine, leucine, and phenylalanine. It was also established that from the 30th up to the 60th day of ripening the amino acids were subjected to transformation. Highest were the amounts of lysine, asparagic acid, glutamic acid, proline, methionine, tyrosine, and leucine. Dur...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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
