Effects of amino acids and albumin administration on albumin metabolism in surgically stressed rats: A basic nutritional study.

Background: Nutrition therapy and administration of albumin preparations are common in postsurgical patients. However, the effects of these interventions on albumin metabolism are unclear. We elucidated the effect of postoperative albumin and/or parenteral nutrition administration on it.

Novel animal model of combined generalized and focal epilepsy.

Thioredoxin, encoded by Txn1, is a critical antioxidant that protects against oxidative damage by regulating the dithiol/disulfide balance of interacting proteins. We recently discovered the Adem rat, an epileptic rat harboring the Txn1-F54L mutation, characterized by wild running and vacuolar degeneration in the midbrain. This study aimed to characterize the classification of epilepsy in Adem rats.

Scn1a and Cacna1a mutations mutually alter their original phenotypes in rats.

This study aimed to examine the effects of Cacna1a mutation on the phenotype of Scn1a-associated epilepsy in rats. We used rats with an N1417H missense mutation in the Scn1a gene and others with an M251K mutation in the Cacna1a gene. Scn1a/Cacna1a double mutant rats were generated by mating both Scn1a and Cacna1a mutants.

Poor mother-offspring relationships in rats with Cacna1a mutation.

Homozygous Groggy dams, which carry a Cacna1a missense mutation, often show no interest in their offspring, leading to frequent offspring deaths due to lack of nurturing. The present study aimed to clarify whether the Cacna1a mutation contributes to impaired attachment behaviors between dam and offspring. The open field test showed that homozygous female rats exhibited markedly short travel distance, whereas no difference was found between the motor activity of heterozygous females and that of wild types (WT).
