Abstract

The effect of postoperative long-term chemotherapy was evaluated in 89 patients who were treated with daily oral administration of 600-800 mg of tegafur for 2 years after gastrectomized because of stage III stomach cancer in our department from 1975 to 1977. Other 128 patients, as control, were given no chemotherapy after undergoing an operation from April, 1967 to the end of 1974. The minimum, crude 5-year-survival rate in the group given chemotherapy was significantly higher (57.3%) than that in the control group (35.2%). Twenty-six patients without lymphnode metastasis and 36 patients with n1 (+) metastasis in the treated group showed significantly higher 5-year-survival rate of 77% and 64%, respectively compared to the control group (46% and 33%, respectively). The patients having n2 (+) metastasis in the treated group, however, showed no significantly higher 5-year-survival rate (30%) compared to the comparable patients in the control (17%). The 5-year-survival rate in 54 cases treated with the total dose of more than 200 g of the drug was 78%, whereas that in other 35 cases receiving lesser dose was 26%. Furthermore, 35 cases given more than 300 g of the drug showed the 5-year-survival rate of 88.6%. These data showed tha...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.
