Neurobehavioral deficits, histoarchitectural alterations, parvalbumin neuronal damage and glial activation in the brain of male Wistar rat exposed to Landfill leachate.

Concerns about inappropriate disposal of waste into unsanitary municipal solid waste landfills around the world have been on the increase, and this poses a public health challenge due to leachate production. The neurotoxic effect of Gwagwalada landfill leachate (GLL) was investigated in male adult Wistar rats. Rats were exposed to a 10% concentration of GLL for 21 days.

Variations in oral glucose tolerance tests: the 100- versus 75-g controversy.

This study compared the results of a 75-g, 3-hour oral glucose tolerance test with those of a traditional 100-g oral glucose tolerance test. Thirty-two pregnant women participated in the study. Each patient served as her own control, undergoing both a 100- and a 75-g oral glucose tolerance test within 1 week.
