Abstract

Evaluate the prognostic value of the early response of the serum estradiol FSH y LH action of leuprolide acetate during the folicular phase, used as an adjuvant to ovarian stimulation in IVF-ET. Were analyzed 31 cycles of stimulation in 26 patients with sterility primary and secondary. Where measured estradiol, FSH, LH on cycle day 2 to 5 for to establish the patterns of response to GnRHa administration. Were compared the response patterns in relation to the number of oocyte captured, estradiol in the day of application of hCG, number of embryos and fertilization rate using (t-student, wilcoxon test and X2). Where observed four distincts patterns of response of estradiol. Pattern A: 133 cycles, presented a prompt elevation of estradiol, followed by a fall on the 4th cycle's day. Pattern B: 9 cycles delayed elevation of the estradiol, followed by a fall on the 6th cycles day. Pattern C: 7 cycles showed persistent elevation of the estradiol. Pattern D: 2 cycles no response of the estradiol (canceled cycles). Was found a significative difference in the estradiol level the day of application of hCG, number of captured oocytes and number of embrions in the pattern A in relation with B and C. No significative difference were found in...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.
