We wish to understand how limbs are positioned with respect to the dorso-ventral axis of the body in vertebrate embryos, and how different regions of limb bud ectoderm, i.e. dorsal ectoderm, apical ridge and ventral ectoderm, originate. Signals from dorsal and ventral ectoderm control dorso-ventral patterning while the apical ectodermal ridge (AER) controls bud outgrowth and patterning along th...

Regional fates in the developing limbs of Drosophila melanogaster are controlled by selector gene transcription factors. Ventral fate in the fly leg is specified by the expression of the ligand Wingless. We present evidence that midline and H15, members of the Tbx20 class of T-box transcription factors, are key mediators of the Wingless signal in the formation of the ventral region of the fly l...

We examined the striatal projections from different cytoarchitectonic regions of the insular cortex using anterograde and retrograde techniques. The shell and medial ventral striatum receive inputs primarily from the agranular and ventral dysgranular insula. The central ventral striatum receives inputs primarily from the dorsal agranular and dysgranular insula. Projections to the central ventra...

Suatu spesies harus memiliki satu taksonomi yang jelas dan disepakati secara global untuk mempermudah para peneliti dalam membahas suatu spesies. Penelitian ini bertujuan mengidentifikasi ikan layang (Decapterus spp.) tertangkap di Perairan Daerah Istimewa Yogyakarta morfologi, morfometrik, meristik. Ikan diperoleh dari tangkapan nelayan Sadeng pada bulan Maret-Juni 2019. Sampel diambil berjuml...
