Nutritional vitamin D deficiency: a case report.

We present a 6-month-old African American male child with a chief complaint of failure to appropriately gain weight despite adequate caloric intake via breastfeeding. While he has met developmental milestones he appears small for age and is diagnosed with failure to thrive after crossing two major growth curve percentiles. After appropriate diagnostic workup, a diagnosis of nutritional vitamin D deficiency (rickets) was reached and supplementation was initiated with ensuing adequate catch-up growth.

Sensitivity of mice to lipopolysaccharide is increased by a high saturated fat and cholesterol diet.

Background: It was hypothesized that a pro-atherogenic, high saturated fat and cholesterol diet (HCD) would increase the inflammatory response to E. coli endotoxin (LPS) and increase its concentration in plasma after administration to mice.

Methods: C57Bl/6 mice were fed a HCD or a control diet (CD) for 4 weeks, and then treated with saline, 0.
