Hearing is a major factor in human quality of life. Mouse models are important tools for discovering the genes that are responsible for genetic hearing loss, and these models often allow the processes that regulate the onset of deafness in humans to be analyzed. Thus far, in the study of hearing and deafness, at least 400 mutants with hearing impairments have been identified in laboratory mouse...
Using the hypoxic (FiO2 = 0.05) mouse model as originally described, the survival time following pretreatment with physostigmine was examined. The maximum increase in survival time was 87% following a physostigmine dose of 0.4 mg/kg. This increase was considerably less than that previously reported for this drug in a hypoxic mouse study wherein the standard method for exposing mice to hypoxia w...
many investigators are interested in finding the new cultural systems that can support the in vitro development of pre-implantation embryos better. previous studies suggested that growth factors such as epidermal growth factor (egf) are important in pre-implantation embryo development and implantation process. on the other hand, it is very important to support post thaw development of frozen em...
background: induction of ovulation in art is necessary for superovulation and the side effects of superovulatory drugs are debated. oxytocin as a natural hormone, have receptors and is synthesized by several reproductive organs. preovulatory presence of oxytocin receptor mrnas in granulosa cells indicating a role for oxytocin in follicular development. objective: the aim of the present study wa...
background: cytotoxic therapy can lead to prolonged azoospermia or even sterility. in the present study, we investigated the morphological changes of mouse testes after gamma-radiation. methods: after anaesthetizing of nmri mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+12...
background: all-trans retinol is a biological antioxidantscavenging the ros in the cell culture. objectives: this studywas conducted to investigate the effect of all-trans retinol infertilization and culture medium on mouse embryo's developmentalcompetence. methods: this study was designed into twoexperiments. in the first experiment, in vitro mature oocytes wereco-cultured with sperm in fertil...
The paper by Singh et al. shows that silibinin inhibits prostate cancer growth in the TRAMP mouse model. Among its other properties, silibinin inhibits the progression of prostate cancer by decreasing angiogenesis and tumor invasion. Identification of the biological effects of herbal remedies such as silibinin is critical for their development as anticancer treatments.
The evolution of drug resistant Plasmodium parasites is a major challenge to effective malaria control. In theory, competitive interactions between sensitive parasites and resistant parasites within infections are a major determinant of the rate at which parasite evolution undermines drug efficacy. Competitive suppression of resistant parasites in untreated hosts slows the spread of resistance;...
