This study examined the source of Ca mobilized by phorbol esters and its requirement for phorbol-induced contraction of smooth muscle cells isolated from the circular and longitudinal layers of guinea pig intestine. Phorbol-12-myristate-13-acetate caused rapid, sustained, concentration-dependent muscle contraction and increase in cystolic free [Ca]i in muscle cells from both layers. Maximal con...

Reducing land fragmentation can theoretically curb cropland abandonment, thus ensuring food security. However, few studies have quantified this relationship using large-scale survey data at the household level. This study adopts a two-way fixed-effects (TWFE) model to examine effect of on abandonment nationally representative panel from China Rural Household Panel Survey (CRHPS). The set contai...
