Abstract

To determine the levels of elements in follicular fluid (FF) of patients undergoing IVF and evaluate the relationship between the concentration of elements in FF, follicular volume, and blood. Prospective blinded study. University-based IVF center. Follicular fluid/blood samples from 6/3 patients, respectively, undergoing IVF. Single follicular aspirations of 33 follicles were performed. Blood samples ( approximately 5 mL) were drawn at the time of oocyte retrieval from 3/6 patients only. The concentrations 26 elements were measured by inductively coupled plasma mass spectroscopy. Trace elements concentrations in follicular fluid and blood. [1] Calcium and magnesium were the most abundant, followed by Cu, Zn, Fe, Cr, Rb. The elements V, Sr, Se, B, As, Pb, Al, Mo, Mn, and Cs were found in trace amounts. The elements Li, Be, Ag, Cd, Ba, Ti, Bi, U were not detected. [2] Element concentrations in small follicles frequently differed from those of large follicles. [3] Element concentrations in large follicles more closely resembled those in blood. Concentrations of elements in FF of small follicles can differ from those of large follicles in the same woman and from those of blood serum. When follicles grow they become filled with flu...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.
