In situ degradation and absorption of [15N]urea in chicken ceca
Comparative Biochemistry and Physiology Part A: Physiology, 1995[15N]Urea was introduced (in situ) into a ligated cecal pouch of chickens to determine if it is degraded therein and absorbed into the blood as ammonia during the following 60 min. A mean of 49% of the introduced urea-15N was recovered from the blood of the mesenteric vein draining the cecal pouch and 26% was recovered from the cecal lumen fluid.

Bacterial Colonization and Degradation of Demineralized Dentin Matrix in situ
Caries Research, 2009Lesion formation in dentin involves demineralization followed by degradation of the exposed organic matrix. Proteinases from microorganisms present in the dentin are believed to play an important role in the breakdown of the dentinal collagen. In this study, the microflora colonizing decalcified dentin matrix, placed in situ, was identified.

Assessment of an in‐situ technique to estimate the degradation of lipids in the rumen
Journal of the Science of Food and Agriculture, 1992AbstractIn‐situ disappearance of alfalfa hay, soybean, soybean meal and maize grain lipids and fatty acids were measured using two dairy cows. Bags were removed after 1, 2, 4 and 8 h incubation. Bacterial colonisation was estimated by labelling bacteria by a 15N infusion into the rumen. Results were then subtracted from calculations.

In Situ SERS Monitoring of Plasmon-Mediated Degradation of Microplastics
Journal of the American Chemical SocietyMicroplastics (MPs) are chemically stable and environmentally persistent pollutants that accumulate in natural ecosystems, posing potential risks to both environmental and human health. Despite growing concern, effective strategies for degrading MPs and elucidating their chemical transformations remain limited.

In situ degradation kinetics of maize hybrid stalks
Animal Feed Science and Technology, 1997Abstract An understanding in plant factors influencing digestion kinetics could help develop maize cultivars, thus improving digestibility and consequently the production of ruminants. The stalk fraction of maize hybrids was used to study the cell wall digestion of hybrids varying from the brown midrib-3 (bm3) and their isogeneic normal (N) to normal

An in situ Raman spectroscopic study of the degradation of PVC
Polymer Degradation and Stability, 1993Raman spectroscopy has been used to study the in situ degradation of PVC in nitrogen and in air at different temperatures. After a rapid initial increase in the number of polyenes, the rate decreases and eventually the concentration becomes constant while the rate of dehydrochlorination is constant over the same period.

Bioremediation via in situ Microbial Degradation of Organic Pollutants
2013Contamination of soil and natural waters by organic pollutants is a global problem. The major organic pollutants of point sources are mineral oil, fuel components, and chlorinated hydrocarbons. Research from the last two decades discovered that most of these compounds are biodegradable under anoxic conditions. This has led to the rise of bioremediation
