Abstract

To produce age-related nomograms for ovarian antral follicle count (AFC) in infertile women. It was done a cross-sectional study of patients attended in the center of assisted reproduction Fêmina, from March 2010 to October 2011. The patients were submitted to transvaginal ultrasonography from day 2 to day 4 of their menstrual period. Patients included were between 21 to 45 years old, with regular menses, two healthy ovaries, without any evidence of endocrinopathies and who gave written informed consent. Patients excluded were smokers, with galactosemia or ovarian cysts, with antecedents of liver disease, ovarian surgeries or who were treated with chemotherapy or radiotherapy. In order to check the evolution of the AFC in relation to patient age, we used the 5th, 25th, 50th, 75th and 95th percentiles. Linear regression was carried out using these percentiles, permitting us to determine the effect of age on the CFA. A total of 172 patients with a mean age of 32.7 years were included in the trial. The male and tubal factors were the main causes of infertility, accounting for 65% of cases. The age-related nomogram for the 5th, 25th, 50th, 75th and 95th percentiles of AFC revealed that changes were best fitted by a linear function....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.
