The vibrational nonlinear dynamics of HOBr in the bending and O-Br stretching coordinates with anharmonicity and Fermi 2:1 coupling are studied with dynamical potentials in this article. The result shows that the H-O stretching vibration mode has significantly different effects on the coupling between the O-Br stretching mode and the H-O-Br bending mode under different Polyad numbers. The dynamical potentials and the corresponding phase space trajectories are obtained when the Polyad number is 27, for instance, and the fixed points in the dynamical potentials of HOBr are shown to govern the various quantal environments in which the vibrational states lie. Furthermore, it is also found that the quantal environments could be identified by the numerical values of action integrals, which is consistent with former research.
The worry of potential residual renal cancer cells in donor kidney after resection of small renal cancer impedes the extensive use of such controversial donor source. To explore the impacts of organ preservation process on the survival of renal cancer cells, we detected cell proliferation and viability of benign and malignant renal cell lines and clinical renal samples after treated with simulated organ preservation process. It was found that the viability and proliferation of malignant renal cells are inhibited much more than that of benign renal cells during prolonged organ preservation. The inhibition of proliferation in benign renal cells is fully reversible, while in malignant renal cancer cells is not fully reversible after a certain time. So potential residual renal cancer cells could be partly inhibited and eliminated by organ preservation process.

What is Visualize?
JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.
How does it work?
We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.
Video X seems to be unrelated to Abstract Y...
In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
