Abstract

The objective of the present study was to assess zinc nutritional status in alcoholic patients with pellagra using plasma, hair, urine and nail zinc levels, as well as the zinc tolerance test. The study was conducted on 81 patients, 73 males and eight females. Zinc parameters were compared with those of 84 individuals with no apparent disease aged 23-45 years. Plasma zinc levels were lower in patients with pellagra than in the controls (P < 0.01). The results of the zinc tolerance test showed that: (1) basal zinc levels were 69.7 +/- 16.8 micrograms/100 ml in pellagrins and 82.3 +/- 34.0 micrograms/100 ml in the controls (P < 0.01); (2) after 1 h the increase in plasma levels was similar in the pellagrin and control groups; (3) during the second hour the increase was more marked in the controls (P < 0.01), and the same was observed during the third and fourth hours (P < 0.05). Urinary zinc excretion (mg/24 h) was higher in pellagrins (P < 0.01). Zinc concentration in hair and toenails did not differ between pellagrins and controls. We conclude that pellagrins present zinc deficiency as demonstrated by plasma and urine zinc levels and by their abnormal response to the zinc tolerance test. We suggest that hair and nail zinc level...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.
