Nutritional and reproductive dynamics of moose near their southern range limit

open access: yesThe Journal of Wildlife Management, EarlyView.
Though southern moose (Alces alces) had relatively low seasonal fluctuations in body fat, their condition was positively associated with pregnancy and adult survival but did not influence recruitment of young. We demonstrated clear signs of nutritional limitation and unexpected patterns of reproductive performance that may be unique to moose living at ...

Combined Effects of Puerarin and Adipose‐Derived Stem Cells on Alveolar Bone Preservation and Inflammation Control in Periodontitis Through p38MAPK Modulation

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study evaluated the effects of puerarin and adipose‐derived stem cells (ADSCs), alone or combined, on p38MAPK activity, alveolar bone preservation, and inflammatory responses in a rat periodontitis (PD) model and in vitro. ADSCs were exposed to various puerarin concentrations to assess cell proliferation, osteogenic differentiation, and ...
