This research paper examined social isolation and aging in Zambia by examining possible predictors. The paper produces evidence on risk factors likely to engender social isolation among the elderly population of Zambia. Snowball sampling was undertaken to select 690 adults aged 60 and over in communities as well as those living in homes for the aged. A structured questionnaire was used to solicit information from respondents. Results show that old people in Zambia experience forms of social isolation ...

The action on muscle spindle afferents, sialogogous action and acute toxicity of lyoniol-A and eleven related compounds were determined. The excitatory action on muscle spindle afferents were measured as the increase in frequencies of the afferent discharge from de-efferented muscle spindles in anesthetized rats. LD50-and salivationtests were conducted using mice. Of the compounds studied, lyoniol-A, lyoniol-B, dihydrolyoniol-B, grayanotoxin-I and grayanotoxin-III were more potent than suxamethonium, ...

N-Substituted 3-glucosyloxy-2-methyl-4-pyridones were synthesized from natural maltol glucoside (III) and primary amines. Aliphatic amines reacted readily with (III) in aqueous methanol under reflux, while aromatic amines required the addition of potassium hydroxide as a catalyst. The aglycones, N-substituted 3-hydroxy-2-methyl-4-pyridones, were obtained by acid hydrolysis of the above pyridone glucosides.

<p style="text-align:justify">This research paper explores the concept of ‘cost sharing’ which became more prominent in Zambia education with the advent of democratic form of governance in 1991. As a way of responding to the ever diminishing tax revenues, government through the education policy of 1996, allowed higher education institutions including public universities to introduce cost sharing as way of improving financial vibrancy, accountability and cost effectiveness. This paper therefore, ...
