AI Article Synopsis
- The study examined the biochemical composition of whole saliva from ten children with chronic renal failure and low caries activity, looking at various components before and after dialysis.
- The mean salivary urea levels were significantly elevated compared to a control group and decreased after dialysis, indicating a change in kidney function.
- Dialysis affected the concentrations of free amino acids and electrolytes in saliva, with basic amino acids increasing while calcium and magnesium levels were notably decreased compared to controls.
Article Abstract
The biochemical composition of unstimulated whole saliva was studied on ten children suffering from chronic renal failure and who, at the same time, displayed a very low caries activity. Various salivary components were studied before (T) and after (To) dialysis and were compared with similar elements of a control group, as well as with blood values. A mean salivary urea concentration of 513 +/- 210 mg/100 ml was found prior to dialysis, whereas after treatment this value dropped to 241 +/- 82 mg/100 ml, about twice as much as in the control group, 110 +/- 48 mg/100 ml. The mean urea concentrations in blood at T and To were respectively 196 +/- 38 mg/100 ml and 53 +/- 22 mg/100 ml. The various free amino acids in the whole saliva of these patients showed different changes in their concentrations as a result of dialysis, with the basic amino acids being considerably increased. Blood electrolytes remained close to the normal range, although calcium was depleted and magnesium lowered by a factor of 10 when compared before and after dialysis, as well as versus the control group.

Background: Nirmatrelvir/ritonavir is licensed for the treatment of mild-to-moderate coronavirus disease (COVID-19) in patients at an increased risk of progression to severe disease. However, data on the real-world plasma exposure to nirmatrelvir/ritonavir remain limited, particularly in Chinese patients. This study aimed to assess the nirmatrelvir/ritonavir trough concentration (Ctrough) and identify its critical factors in hospitalized Chinese patients treated with nirmatrelvir/ritonavir 300 mg/100 mg twice daily over a 5-day course.

Today, active packaging has become essential to increase food safety and decrease food spoilage. In this study, the aim was to delay spoilage and increase the shelf life of rainbow fish fillets with a new hybrid nanocomposite active packaging. Packaging was fabricated with Ethylene vinyl acetate and active compounds such as rosemary extract, zinc oxide nanoparticles, and modified iron (Fe-MMT).
