Sustainable generation of homogeneous Fe(VI) oxidant for the room temperature removal of gaseous NO by electro-scrubbing process.

A high valent Fe(VI) homogenous catalyst was synthesized following electrochemical route for the efficient removal of a greenhouse gas (NO) by mediated electro catalytic oxidation (MEO) in an electro-scrubbing process. This paper describes the room temperature degradation of NO using a consistently generable hexavalent Fe(VI) homogenous catalyst. The ferrate (VI) was electrochemically generated by employing a membrane divided cell, and quantified by monitoring the changes in the ORP (oxidation/reduction potential) along with a potentiometric titration by the chromite method using chromium Cr(III) as a titrant.

Identification of Synergistic Interaction Between Cannabis-Derived Compounds for Cytotoxic Activity in Colorectal Cancer Cell Lines and Colon Polyps That Induces Apoptosis-Related Cell Death and Distinct Gene Expression.

Colorectal cancer remains the third most common cancer diagnosis and fourth leading cause of cancer-related mortality worldwide. Purified cannabinoids have been reported to prevent proliferation, metastasis, and induce apoptosis in a variety of cancer cell types. However, the active compounds from flowers and their interactions remain elusive.

How the mesencephalic locomotor region recruits hindbrain neurons.

This chapter summarizes experiments which were designed to reveal how repetitive electrical stimulation of the mesencephalic locomotor region (MLR) recruits nearby hindbrain neurons into activity, such that locomotion can ensue in the tiger salamander, A. tigrinum. The MLR stimulus strength was subthreshold or near-threshold for locomotor movements to ensue.

Behavior of hindbrain neurons during the transition from rest to evoked locomotion in a newt.

Trains of electrical stimuli were delivered to the mesencephalic 'locomotor region' in the rough skin newt. The current (3-12 mcA) and the interstimulus interval (100 to 200 ms) were adjusted so that locomotion arose in approximately 10 s, or so that the train remained subthreshold for initiation of locomotion. Impulses of single neurons in the hindbrain were recorded during the transition period from rest to locomotion.

[Responses of medullary and spinal neurons to simultaneous stimulation of two locomotor points].

Responses of neurons in the medulla and cervical segments to simultaneous repetitive (50 pps) stimulation of two locomotor points (LPs) by currents in the range of 1 to 2 thresholds of locomotion were studied. In most cases a neuron responded to stimulation of only one LP. Stimulation of the second LP enhanced usually the firing index of that response, if it was low, diminished it, if it was high and did not influence it, if it was about 0.
