Abstract

Radiation reactions were assessed in 140 pancreatic cancer patients. They were noted in 103 (73.5%) patients: general radiation reactions in 62 patients and local reactions in 41. Noticeable radiation reactions were noted in 17.5%, moderate in 36.9% and insignificant in 45.6% of the patients. The use of braking radiation with the energy of 18-25 MeV caused a decrease in the total number of radiation reactions to 20%, the number of noticeable radiation reactions as compared to those in gamma-beam therapy reduced 3-fold. Changes of external secretory and insular function of the pancreas caused by irradiation were studied. It was established that radiation therapy caused no inhibition of these functions, and in 45.9% of the patients it brought about their improvement or normalization. Complications of radiation therapy were observed after 7-48 mo in 21 patients for gamma-beam therapy and presented with vertebral osteopathy in the exposed site, intestinal trophic ulcer and peptic ulcer recurrence. Radiation reactions caused the termination of therapy of 6 (4.3%) patients, a radiation therapy plan in 21 (15%) patients was changed and a 5-7-day interruption or a split course of irradiation was recommended. The main reaction was a gen...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.
