Evaluation of Embryos Derived from in vitro Fertilized Oocytes Reconstructed by Meiosis-II Chromosome Transplantation from Aged Mice to Ooplasms of Young Mice
Background To assess embryos derived by the transfer of meiosis-II chromosomes (M-II-t) from aged mice oocytes into ooplasms from younger mice to overcome the problem of age-related decline in female fertility. MaterialsAndMethods The developmental capacity karyotype and ultrastructure of reconstructed oocytes derived from meiosis-II chromosome transplantation from aged mice into the ooplasms o...
متن کاملAnti-ageing effect of a lactococcal strain: analysis using senescence-accelerated mice.
The effects of oral administration of a lactococcal strain on physiological changes associated with ageing were investigated using senescence-accelerated mice (SAM). SAM develop normally, but then show an early onset and irreversible advancement of senescence. SAMP6 is a SAM strain that develops osteoporosis with ageing. Oral administration of heat-killed Lactococcus lactis subsp. cremoris H61 ...

متن کاملDrinking Hydrogen Water Ameliorated Cognitive Impairment in Senescence-Accelerated Mice
Hydrogen has been reported to have neuron protective effects due to its antioxidant properties, but the effects of hydrogen on cognitive impairment due to senescence-related brain alterations and the underlying mechanisms have not been characterized. In this study, we investigated the efficacies of drinking hydrogen water for prevention of spatial memory decline and age-related brain alteration...
متن کاملNanonized black soybean enhances immune response in senescence-accelerated mice
Soy isoflavones may have applications in cancer prevention and anti-inflammation, therefore this study was conducted to investigate the effect of dietary supplementation with black soybean on the immune response in the senescence-accelerated-prone mice (SAMP8) and -resistant mice (SAMPR1, as controls). The mechanism of isoflavones was also investigated. Six-month-old male SAMP8 and SAMR1 mice w...
