The ash mudstone in some oil formations is highly water-sensitive. formation fractured, and the risk of well leakage collapse not negligible. This study presents a countermeasure for prevention, based on “force-chemistry synergistic balance” approach utilization environmentally friendly efficient hydration inhibitors. relevance this demonstrated considering drilling fluid system with high potas...

HALJAMXE, H., A. LINDE, AND B. AMUNDSON. Comparative analyses oj capsular fluid and interstitial @id. Am. J. Physiol. 227(5) : 11991205. 1974.-Interstitial fluid from rabbits was collected from implanted capsules and with a “liquid-paraffin cavity” technique. The fluids were analyzed for K+, Naf, Cl-, proteins, and glycosaminoglycans. The rate of transvascular exchange of albumin-1311 to the fl...

Our purpose was to study the interaction between Na(+) content and fluid volume on rehydration (RH) and restoration of fluid spaces and cardiovascular (CV) function. Ten men completed four trials in which they exercised in a 35 degrees C environment until dehydrated by 2. 9% body mass, were rehydrated for 180 min, and exercised for an additional 20 min. Four RH regimens were tested: low volume ...

Glucose levels in 154 random specimens of lumbar cerebrospinal fluid, normal as regards cell and protein content, were estimated by the glucose-oxidase method and a mean value of 60.5 mg./100 ml. (S.D. 7.3) was obtained. In 33 fasting patients subject to air encephalography the mean cerebrospinal fluid (C.S.F.) glucose level was 56.5 mg., and mean blood glucose level 65.5 mg. with an average C....

Western blot of synovial fluid has been widely used for osteoarthritis (OA) research and diagnosis, but there is no ideal loading control for this purpose. Although β-actin is extensively used as loading control in western blot, it is not suitable for synovial fluid because it is not required in synovial fluid as a cytoskeletal protein. A good loading control for synovial fluid in OA studies sh...

BACKGROUND/AIM Fluid volume overload occurs in chronic kidney disease (CKD), leading to the compensatory release of natriuretic peptides. However, the elevated cardiac peptides may also be associated with malnutrition as well as volume overload. METHODS Body fluid composition was measured in 147 patients with CKD between 2009 and 2015, and its relationship to brain natriuretic peptide (BNP) l...

It has been suggested that high zinc concentrations found in men may prevent Trichomonas vaginalis from being established in the male reproductive tract. In this investigation T vaginalis was readily killed at concentrations of zinc that occur in the prostatic fluid of healthy men (minimum trichomonacidal concentration (MTC) of 6.4 mmol/l). T vaginalis was also shown to be killed by human prost...
