Interaction of polymer-containing injected fluids with shale is a widely studied phenomenon, but much is still unknown about the interaction of charged polyacrylamides such as anionic and cationic polyacrylamides with shale. The nature of interaction of charged polyacrylamides with shale is not well understood, especially from the perspective of assessing the potential for polyacrylamides to cause formation damage. Zeta potential and rheological measurements were made for Chattanooga and Pride Mountain shales suspended in polyacrylamide solutions with and without inorganic salts and tetramethyl ammonium chloride（TMAC）. The change in zeta potential and viscosity with time was recorded. The magnitude of decrease in the absolute value of zeta potential with time is indicative of adsorption of polymer on the surface of shale and serves as a measure of the extent of polymer interaction with shale. The salts that were used in this study are potassium chloride（KCl）, sodium chloride（Na Cl）. This study quantified the interaction of anionic and cationic polyacrylamide with different North American *** the experimental results, it was determined that the polyacrylamides can interact strongly with shale, particularly the cationic polyacrylamide. The objective of this study was to determine the extent of interaction of anionic and cationic polyacrylamide with each shale sample in the presence of additives such as salts.

Alcohol use disorder(AUD) is a global health concern associated with several *** health problems related to AUD, such as cognitive deficits, have been linked to *** use has been associated with changes in neuroimmune activity, although current literature has yielded mixed results. For example, markers of gliosis, including translocator protein 18-kDa(TSPO), proinflammatory cytokines, glutamate(Glu), and myo-inositol(mI), are disrupted in the alcohol-dependent brain. Further, neuroinflammatory-related phenomena including membrane turnover, blood brain barrier(BBB) permeability, and adenosine release have also shown alterations in AUD. However, current literature remains inconclusive about the directionality of these changes. Both in vivo and in vitro studies have provided insight on the relationship between alcohol use and neuroinflammatory processes, suggesting considerable treatment potential for alcohol use disorder and its inflammatory comorbidities. Here, we review current neuroimaging literature assessing the impacts of alcohol use on neuroimmune activity in the brain.

The commonest type of simple vaginal cyst is the Mullerian cyst. These are typically lined by columnar epithelium and contain serous or mucinous f luid. If blood is found in the cyst, the source is usually due to the presence of endometrial elements in the cyst wall. The cyst is then termed an endometriotic cyst. In this case report, we have described a woman with a symptomatic 3 cm upper vaginal cyst who underwent surgical excision of the cyst. The cyst cavity was found to be full of old dark blood and mucous, however the wall contained no endometrial tissue and was lined by columnar epithelium which stained positive for mucous with mucicarmine. No cause for the intracystic hemorrhage was identif ied. We conclude that intracystic hemorrhage can occur in a simple Mullerian vaginal cyst in the absence of endometrial components.
