Abstract

To investigate the prognostic value of lymphatic vascular invasion (LVI) for stage I( gastric cancer patients after radical gastrectomy. Clinicopathological and intact follow-up data of 469 stage I( gastric cancer patients who underwent radical gastrectomy with R0 resection and were pathologically proven as gastric adenocarcinoma without other malignancy at the Department of Digestive Surgery, The First Affiliated Hospital, The Fourth Military Medical University between February 2009 and December 2012 were retrospectively collected. Chi square test was used to examine the relationship between LVI and clinicopathological data; Log-rank test was used for survival analysis; Cox proportional hazards model was used for univariate and multivariate analysis to explore the prognostic influence of LVI on stage I( gastric cancer patients. A total of 469 patients were enrolled, including 360 male (76.8%) and 109 female patients (23.2%). Median age was 58(25-82) years. There were 114 T1a cases (24.3%), 195 T1b cases (41.6%), and 160 T2 cases (34.1%). There were 439 (93.6%) cases without lymph node metastasis and 30 cases with lymph node metastasis. Presence of LVI was found in 52 patients (11.1%). LVI was closely associated with tumor grad...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.
