The DRN-VLO pathway via distinct 5-HT synaptic mechanisms modulates neuropathic pain–induced depressive-like behaviors in mice [PDF]
Background The neuronal activities within the dorsal raphe nucleus (DRN) and the ventrolateral orbital cortex (VLO) are strongly implicated in the development of depression, a condition comorbid with chronic pain.

Flotation tests using sorghum flour as a pyrochlore depressant [PDF]
Cornstarch is one of the most used depressants in mineral flotation operations. However, corn is a costly input for the Brazilian mineral industry, since its main destination is to serve the animal and human food market and exports.

New reagents for controlling of H2O2 by metal sulfide and its effect in sulfide mineral floatation [PDF]
Our recent studies revealed that the ground sulphide minerals in contact with water generate H2O2 but its effect on the oxidation of pulp components and hence in deteriorating the concentrate grade and recovery in flotation has not been explored yet. The

Hematite and quartz microflotation using millet starch as depressant
Brazil is among the world's largest iron ore producers. The standard concentration method is reverse cationic flotation using amines, and their derivatives, such as quartz collector and corn (as either grits, flour, or starch) as the hematite depressant.

Investigations on the Reverse Flotation of Quartz/Hematite Using Pullulan as a Novel Depressant
The traditional hematite depressant starch has the disadvantages of poor solubility and high viscosity. In this study, a novel hematite depressant, pullulan, with better performance and flotation effect than starch was found.

The effect of composition and shape variations on compressive strength slag depressant
The steel-making process begins with a reduction process carried out in a blast furnace (BF) then continues with the refining process in the converter. In the refining process, there is a slag foam formed from the reaction of oxygen with hot metal.
