Consequences of uterine blood loss caused by various intrauterine contraceptive devices in South American women. World Health Organization Special Programme of Research, Development and Research Training in Human Reproduction

Increased menstrual blood loss (MBL) associated with intrauterine device (IUD) use may precipitate or aggravate iron deficiency anaemia, adversely affecting the health of women particularly those from developing countries. Studies were conducted to define the association of MBL and iron status in South American women; to determine the level of MBL induced by IUD use which would result in iron depletion, the length of time for this depletion to occur and, comparing various IUDS, to determine if any currently tested IUDs are suited to long-term use in South American women. A total of 395 women received one of 5 types of IUDs in Santiago, Chile, and Juiz de Fora, Brazil: Lippes Loop, Multiload-250 and Multiload-375 were used in both centres; in Santiago some subjects received the Copper-7 or ProgestasertR devices and in Juiz de Fora, the TCu 200 and the T-Chloroquin IUDs were also tested. MBL and haemoglobin (HGB) were measured for 3 menstrual cycles before insertion, and following insertion, at one, two, four, six, nine, twelve, eighteen and twenty-four months in the majority of cases. Serum ferritin was measured before insertion and at intervals of six months. Mean values of MBL prior to IUD insertion in both centres varied from...Continue Reading

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.

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.

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.

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.


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.

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.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.
