Pap stain was first developed by Dr GN Papanicoloau in 1947 and since then it has been used successfully to screen cervical cancer. In fact, it has reduced the incidence of cervical cancer by 70% especially in developed countries having well planned screening programs. However, the stain has undergone various modifications from regressive conventional method to progressive rapid Pap staining wh...

INTRODUCTION Right ventricle (RV) apical pacing is associated with increased incidence of heart failure due to left ventricle (LV) desynchronization. We aim to investigate extracellular matrix (ECM) remodeling of the LV in dogs with atria-sensed RV apical pacing. METHODS AND RESULTS Dogs with pacemakers underwent AV nodal ablation. After 12 weeks of atria-sensed obligatory RV pacing, LVs were...

Basic postharvest work on 'Fuerte' avocado fruit cell wall anatomy and ultrastructure was carried out from fruit harvest to postclimacteric stage. Mesocarp samples were analyzed with light microscopy, scanning electron microscopy and transmission electron microscopy. Irregularity of the cell wall increased, microfibrils became disorganized, and some dissolution of the middle lamella was observe...
