Abstract

Our aim was to draw up a first general view of cancer pathology among the EDF-GDF women thanks to the cancer register among active employees created by the social security department of the French national electric and gas company EDF-GDF. Between 1978 and 1992, 764 cases of cancer were diagnosed. Breast cancer was the most common (52.4%), followed by gynaecological cancers: uterus (8.6%) and ovary (6.2%), and colon and rectum cancers (5.4%). The age-standardized breast cancer incidence using the 1978-1982 period as a basis increased over time. A higher incidence for breast cancer and a lower incidence for uterus cancer were observed among the EDF-GDF women during the 1978-1982 and 1983-1987 periods, compared to French women of same age. The study of the relationship between breast cancer risk and socioeconomic status, by means of indirect standardization, showed that the breast cancer risk increased with increasing socioeconomic status. Thus manual workers had a lower breast cancer risk than the EDF-GDF woman cohort (SIR = 0.72), foremen had the same risk (SIR = 1.05) and managers had a significantly higher risk (SIR = 1.64). Moreover a case-control study showed that the change in socioeconomic status between the beginning (20...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.
