Striking the right balance between excitation and inhibition
Neurons in the brain and spinal cord come in two flavors, excitatory neurons that transmit and amplify signals, and inhibitory neurons that inhibit and refine those signals. Although investigators have long appreciated that these two classes of neurons exist in the central nervous system, little is known about how cells decide to become inhibitory or excitatory during embryonic development. Rese...Decontamination and inhibition of ribonucleases
It is common knowledge in most laboratories that RNA is more susceptible to degradation than DNA. Unlike Deoxyribonucleases (DNases), which require metal ions for activity (and can therefore easily be inactivated with chelating agents such as EDTA), ribonucleases (RNases) have virtually no cofactor requirements and adv...Measurement of proteasome inhibition in live cells in Molecular Devices microplate fluorometers
Proteins inside eukaryotic cells exist in a dynamic state, in a highly-regulated balance between synthesis and degradation. Whereas prot...A DELFIA Assay for Inhibition of PARP
The DELFIA time-resolved fluorescence assay for inhibition of poly(ADP-ribose) polymerase (PARP) is a 96-well microplate assay that measures the inhibition of PARP-activated incorporation of biotinylated nicotinamide adenine diphsophate (NAD). The incorporation is detected using Europiumlabelled streptavidin. The method is a convenient way to screen test compounds for PARP activity in...Inhibition of morphine tolerance by spinal melanocortin receptor blockade
Recent research suggests that the melanocortin system is an important component influencing the changes in the spinal neuronal plasticity observed after chronic morphine administration//. The chronic use of morphine is accompanied by the development of morphine tolerance, which is one of the major problems associated with opiate treatment. Possible modulation of opioid effects by melanoc...Anonymity Helps In Overcoming Inhibitions During Online Counseling
Online counseling through Internet is gaining momentum slowly but surely as anonymity assists the patient to chat freely with the practitioner// and discuss problems of any sort, as they do not come face to face with them. If the person being talked to is not visible, it is easier for the client to speak about terrible experiences or problems. "Psychotherapy is treatment fo...Inhibition of Colorectal tumor growth by Grape seed extract
Scientists have found marked inhibition of colorectal tumor growth by certain chemicals in grape juice in both cell cultures and in mice. The anti-cancer effects of this// extract in other types of tumor have previously been proven by these researchers. This study is included in the October 18 issue of Clinical Cancer Research. In this study, advanced colorectal tumors showed a reduct...Pseudocholinesterase, Dibucaine Inhibition
