I don’t know because you never put the following particles
The answer to this question is d
Explanation:
- <em>Presynaptic mechanism:</em> one way to modify the synaptic transmission before it happens is affecting transmitters release, one example is calcium channel blockers (for example, verapamil), this action won't allow transmitters out, therefore, there won't be a synaptic transmission.
- <em>Postsynaptic mechanism:</em> one method to modify synaptic transmission after it happens is blocking the transmitter receptors, one example of this is antipsychotic drugs that block dopamine receptors.
I added some images with another examples for both cases. I hope you find this information interesting! Good luck!
Cancer registries are part of the national NCD surveillance system. Population-based registries provide invaluable information on the trends in cancer incidence, while hospital-based registries provide information on the clinical diagnosis, cancer staging, treatment modalities, and survival outcomes. In Japan, cancer incidence is monitored through population-based and hospital-based cancer registries by the Japanese Association of Cancer Registries, in collaboration with 34 prefectural governments. The registries are supported and maintained by the Research Center for Cancer Prevention and Screening at the National Cancer Center. In Singapore, a comprehensive population-, clinic-, hospital-, and laboratory-based cancer registration has been performed by the Singapore Cancer Registry since 1968. Comprehensive cancer registration has been achieved through collation of data obtained from a combination of sources: (1) physician notifications, (2) pathology records, (3) hospital records, and (4) mortality data from the national Registry of Births and Deaths. Since 2009, cancer notification has been made mandatory to ensure completeness of surveillance.
