Abstract

To measure the effect of body mass index (BMI) versus calorie intake and physical activity (PA) on the outcomes of assisted reproductive technologies (ART). A prospective study was performed on 236 infertile women who underwent in vitro fertilization. BMI, level of PA and calorie intake were assessed at study entry, and associations between these variables and ART outcomes were analyzed. Participants were divided into four groups based on BMI and PA: normal BMI/inactive, normal BMI/active, overweight/inactive and overweight/active. BMI, adjusted for age, level of PA, calorie intake and aetiology of infertility, was not associated with the number of oocytes retrieved, fertilization rate, cleavage rate, number of embryos, number of high-quality embryos or pregnancy rate. For women aged <36 years, the number of oocytes retrieved and the number of embryos decreased with increasing BMI, independent of calorie intake and PA. The fertilization rate, cleavage rate, number of high-quality embryos and pregnancy rate were not associated with BMI. The number of oocytes retrieved was significantly higher in women of normal weight compared with overweight women, regardless of the level of PA. Age has a strong negative effect on ART parameter...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.
