Trace elements status of fetuses from ewes fed a copper-deficient ration

Abstract

Tissue samples were taken from 130-day-old fetuses from ewes fed a synthetic diet low in copper (Cu), a Cu-supplemented synthetic diet, or a roughage diet adequate in Cu content. The fetal liver and kidney Cu concentrations were substantially lower when the dams were fed the Cu-deficient ration than when they were fed the Cu-supplemented ration or natural diet. Differences between dams' rations in Cu concentrations for the other 3 fetal tissues (spleen, heart, and lung) were small. Differences among groups in fetal tissue iron concentrations were not significant at the P greater than 0.05 level. Concerning zinc concentrations, there were significant interactions between dams' diets and fetal tissues, mainly attributable to differences between rations in liver, heart, and kidney zinc levels. For manganese, the difference among dams' rations and among fetal tissues were significant at the 1% level, but the interactions of ration x tissue were also significant. Heart and spleen manganese concentrations were substantially higher in the fetuses from dams given Cu-deficient diet than in fetuses from dams fed Cu-adequate diet.

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.

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.
