Abstract

The diagnosis of pancreatic lesions can be improved with the aid of the diagnostic needle aspiration procedure under computed tomographic guidance. The computer aided diagnostics should be used to distinguish degenerative changed cells of chronic pancreatitis from cells of well differentiated carcinomas. Investigations are performed with a Jenaval microscope (Carl Zeiss Jena), solid state camera C-1000-35 (Hamamatsu Japan) coupled with minicomputer (Typ 1 102 F ICE Rumania). Multivariate discrimination using 35 features of each nucleus (20 fine needle aspirations of pancreatic carcinomas, 20 fine needle aspirations of chronic pancreatitis of histological controlled autopsies with 8,000 nuclei of Feulgen-reaction and 4,000 nuclei hemalum-eosin-stained of the same material) provides a classification result for single cells of 81% of Feulgen-reaction and 77% by hemalum-eosin-staining. Nonessential differences between the Feulgen-reaction and hemalum-eosin-staining are found by the single cases of fine needle aspiration biopsies of pancreatic carcinomas and nontumorous pancreatic lesions.

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.
