EFFECTS OF HEMIZYGIA WELWITSCHII LEAF EXTRACT FRACTIONS ON POSTHARVEST INFESTATION OF MAIZE BY SITOPHILUS ZEAMAIS MOTSCULSKY (COLEOPTERA: CURCULIONIDAE)

As part of on-going efforts to use eco-friendly alternatives to chemical pesticides, leaf powder of Hemizygia welwitschii was sequentially extracted in hexane, acetone and methanol.Bioassays were carried out to establish the most active fraction(s) against Sitophilus zeamais in maize.Maize grains (50 g) were treated with concentrations within the r

Hypertrophic obstructive cardiomyopathy (HOCM) is one of the most common hereditary heart diseases.The severely hypertrophied interventricular septum combined with the systolic anterior movement (SAM) of the mitral valve (MV) frequently cause a significant pressure gradient in the left ventricular outflow tract associated with varying degrees of mi
