Abstract

Pneumonia in the elderly often occurs repeatedly, and the mortality rate from pneumonia continues to remain high today despite the usual use of antibacterial chemotherapy. Therefore, we conducted immunotherapy using a polyvalent bacterial vaccine (broncasma Berna). We treated 54 elderly patients with Broncasma Berna, containing chief bacterial pathogens responsible for pneumonia in the elderly. Clinical results obtained during 2 years were compared with those of 18 subjects not treated with Broncasma Berna. The survival rate was 64.8% for the group treated with Broncasma Berna and 50% for the group not treated. The frequency of contraction of pneumonia decreased significantly in the group treated. Clinical efficacy was obtained in 63% of the group treated to prevent pneumonia. The death rate from pneumonia was 17.6% for the group treated and 44.4% for the group not treated. Immunologically, reinforcement in humoral and cellular immunities was indicated by immunoglobulin values, positive tuberculin skin tests, and an increase in lymphocyte stimulation index values for Broncasma Berna. Significant pathogens in sputum disappeared or decreased in 6 (54.6%) out of 11 patients. Side effects such as pain or redness at the site of inje...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.
