Abstract

The description, evaluation and management of the main problems emerging during ovulation stimulation in the in vitro fertilization (IVF) programs, include the guidelines to apply this methodology and to select the patients; the ovarian stimulation and oocyte recovery procedures, as well as to emphasize the importance of establish and know the rejection and cancellation rates in these programs. During ovulation stimulation, abnormalities can emerge at different times of the procedure. Basal serum follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) levels on cycle day 3, are helpful in prediction of patients stimulation response and IVF outcome. Patients with elevated FSH levels at the beginning of the menstrual cycle present a short follicular phase with a rapid spontaneous LH surge; likewise, the predominance of LH on day 3 produces a "multi-follicular response", when the usual stimulation protocol is used. All these patients behave poorly in terms of E2 response, quality of the oocytes retrieved and pregnancy rates. If the estrogen levels are low (less than 20 pg/ml) or very high (greater than 80-100 pg/ml) on cycle day 3, the response in terms of oocyte recovery and LH levels will not be adequate....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.
