Abstract

The purpose of this study was to evaluate the clinical significance of multiple focal pure ground-glass opacities (GGOs) on high-resolution CT images of patients with lung cancer. The cases of 23 patients with proven lung cancer and associated multiple focal pure GGOs on high-resolution CT images were retrospectively reviewed. The number, size, distribution, and morphologic characteristics of focal pure GGOs were evaluated. Serial changes in focal pure GGOs that were not surgically resected were analyzed at follow-up high-resolution CT. The number of focal pure GGOs was 196 in total. The size of the opacities ranged from 2 to 30 mm in largest diameter. Lung cancer and focal pure GGOs were seen in the same lobe and/or in the other lobes. One hundred seventy-one of the lesions (87%) had a well-defined border or round shape. Histologic findings were obtained for 15 lesions representing 74 focal pure GGOs that were surgically resected: 11 atypical adenomatous hyperplasia lesions, three bronchioloalveolar carcinomas, and one lesion of focal fibrosis. In 110 of the cases of focal pure GGOs, all of which were followed up with HRCT for a median duration of 1,351 days, the size of 105 lesions (95%) did not change, the size of one decrea...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.
