Early-life dietary transitions reflect fundamental aspects of primate evolution and are important determinants of health in contemporary human populations. Weaning is critical to developmental and reproductive rates; early weaning can have detrimental health effects but enables shorter inter-birth intervals, which

Interstitial cells of Cajal (ICC) generate slow waves in gastrointestinal (GI) muscles. Previous studies have suggested that slow wave generation and propagation depends on a voltage-dependent Ca(2+) entry mechanism with the signature of a T-type Ca(2+) conductance. We studied voltage-dependent

  2. Hi, These Barium dendritics are grindable. I mean as a powder form to use as the precursor. Thank you Manasa

    1 answer
    1. The grinding of barium dendritic pieces into powder has not been attempted internally. A possible option would be to mill the barium dendritic or to shave it. However, based on the physical properties of barium, it may be difficult to grind to a powder.
      Please note that oxide will form in the presence of air.
