Abstract

The vitamin C and iron ingestion level was evaluated in adolescents during the three phases of the menstrual cycle. The food intake of 30 adolescents was analyzed during the premenstrual, menstrual, and postmenstrual phases, by the registration technique, with the analysis of two registrations per individual, in each phase. The prevalence estimate was done considering six dietary registrations for each adolescent. The patterns used as reference were the Dietary Reference Intakes (DRI) - Estimated Average Requirement (EAR) from Institute of Medicine - IOM (2001), using the probability approaches and the cut - point method for the iron and vitamin C respectively, in addition to the values from the Recommended Dietary Allowances (National Research Council). The adolescents were aged 15.5 +/- 1.7; the age of the menarche was 11.8 +/- 1,1; and gynecological age 3.6 +/- 1.9. The medial consumption of iron was 10.6 mg/day and of vitamin C 77.6 mg/day. It was observed by DRIs-EAR an estimate of inadequacy for iron of 22.6% and for vitamin C of 34% and by National Research Council, 63.3% and 20%, respectively. Despite the divergence among the patterns, both results shows a nutritional risk for the studied population. The accomplishment ...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.
