Abstract

The composition of the uterine fluid is of importance for the development of the embryo. The ionic composition of the uterine fluid is determined by transport processes in the uterine epithelium. The aim of the present study was to investigate whether nicotine can affect the ion transport processes and ultrastructure of the uterine epithelium in mouse and rat. The effects of nicotine on the uterine epithelium were compared with those on kidney and liver. Nicotine was administered to mice as an intraperitoneal injection of a 1 microgram/l nicotine solution twice daily for 8 days, or in the drinking water (108 microM nicotine) for 15 days, whereas rats received nicotine in their drinking water for 10 days (54 or 108 microM nicotine). In addition, primary cultures of endometrial cells were exposed to nicotine in vitro. Changes in morphology were examined by transmission electron microscopy and changes in elemental content by X-ray microanalysis. Nicotine caused a significant decrease in the concentrations of Na, K, and Cl in the uterine fluid and in the endometrial cells in situ. Similar changes in elemental concentrations were observed in endometrial cells in vitro. Ultrastructural changes in endometrial cells included swollen an...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.
