Abstract

The usefulness of mediastinoscopy for lung cancer was retrospectively evaluated for the aspect of prognosis. The subjects were 421 patients with primary lung cancer except exploratory thoracotomy. In the MD(+) group, there was no difference in prognosis between right and left sided thoracotomies, but in the MD(-) group there was a tendency for poorer prognosis in the left-sided thoracotomy (p < 0.1). In the right-sided thoracotomy, there was no difference of prognosis between the MD(+) group and MD(-) group. On the contrary, in the left-sided thoracotomy there was a statistically better prognosis in the MD(+) group than in the MD(-) group (p < 0.05). In the left-sided thoracotomy group, there was a statistically better prognosis in the MD +) group than in the MD(-) group in the pN 0 or pN 1 group (p < 0.01), but there was no difference of prognosis in the pN 2 group. In lung cancer of the left side, the mediastinal lymph node dissection would be more incomplete because of the presence of the aorta and the mediastinal lymph node metastasis would tend to be missed. Mediastinoscopy gives the right diagnosis of mediastinal lymph node metastasis and an accurate staging of lung cancer. Mediastinoscopy is very useful especially in the...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.
