Gene Expression and the Physiological Role of Transforming Growth Factor-α in the Mouse Pituitary [PDF]

, 2003
Transforming growth factor-alpha (TGF-alpha), a member of the epidermal growth factor (EGF) family, is produced within the mouse anterior pituitaries. However, the cell types of TGF-alpha-expressing cells and the physiological roles of TGF-a within mouse

Modeling chronic periodontitis in rats: Persistent alveolar bone loss mediated by periodontal pathogens

Animal Models and Experimental Medicine, EarlyView.
Irrigation of periodontal pockets with human periopathogens, in combination with a 14‐day ligature‐induced periodontitis protocol, significantly enhances alveolar bone loss and sustains bacterial colonization for up to 28 days following ligature removal, thereby more closely replicating the chronic nature of human periodontitis compared to the ligature

A systematic review of transgender male rodent model methodology

Animal Models and Experimental Medicine, EarlyView.
Summary of successful transgender male rodent model methods. Testosterone enanthate or cypionate injected SC or IM once per week at 18 mg/kg in mice or 3 mg/kg in rats should effectively match naive male testosterone levels of their respective species.

Gonadotropin-Releasing Hormone Increased Pregnancy in Suckled Beef Cows Not Detected in Estrus and Subjected to a Split-Time Artificial Insemination Program

, 2018
Estrus-synchronization programs allow insemination of all females in a herd at one fixed time on the first day of the breeding season. Inseminating cows after they have expressed estrus increases pregnancy rate (PR) compared with cows that do not display

The efficiency of vaginal temperature measurement for detection of estrus in Japanese Black cows

Journal of reproduction and development, 2016
Recently, weak estrous behavior was assumed to be the cause of a decline in breeding efficiency in cattle. The present study investigated the effect of measuring the vaginal temperature on the detection of estrus in Japanese Black cows. First, the effect

Evaluation of a modified triple‐combination anesthesia using dexmedetomidine in mice

Animal Models and Experimental Medicine, EarlyView.
Development of a modified ketamine‐free anesthetic (dMMB) using dexmedetomidine. To improve the safety and recovery profile of conventional MMB, we developed dMMB by replacing medetomidine with dexmedetomidine. This ketamine‐free formulation showed comparable anesthetic depth and enhanced thermoregulation, avoiding unnecessary isomers for safer use ...

Evaluation of Level of Milk Potential on Nutrient Balance in 2- and 4- Year- Old May- Calving Range Cows Grazing Sandhills Upland Range [PDF]

, 2020
A modeling study evaluated the effects of milk production level on nutrient balance in May- calving cows grazing Sandhills upland range during the breeding season. Forage quality of upland range peaks in June and steadily declines in July until November.

Generating golden Syrian hamsters with conditional alleles via zygote microinjection of CRISPR/Cas9

Animal Models and Experimental Medicine, EarlyView.
We established the first conditional knockout (cKO) model in the golden Syrian hamster by CRISPR/Cas9‐mediated genome editing. Cas9 protein, two sgRNAs, and a donor plasmid carrying loxP‐flanked exon 2 of the ApoF gene were microinjected into one‐cell embryos. The floxed allele was efficiently generated (up to 27%) and transmitted through the germline.
