Dysregulation of gallbladder ion and water absorption and/or secretion has been linked to cholesterol crystal and gallstone formation. We have recently demonstrated that obese, leptin-deficient (Lep(ob)) mice have enlarged gallbladder volumes and decreased gallbladder contractility and that leptin administration to these mice normalizes gallbladder function. However, the effect of leptin on gal...

Dietary fats and sodium are both palatable and are hypothesized to synergistically contribute to ingestive behavior and thereby obesity. Contrary to this hypothesis, C57BL/6J mice fed a 45% high fat diet exhibited weight gain that was inhibited by increased dietary sodium content. This suppressive effect of dietary sodium upon weight gain was mediated specifically through a reduction in digesti...

This study assessed whether replacing sweat losses with sodium-free fluid can lower the plasma sodium concentration and thereby precipitate the development of hyponatremia. Ten male endurance athletes participated in one 1-h exercise pretrial to estimate fluid needs and two 3-h experimental trials on a cycle ergometer at 55% of maximum O2 consumption at 34 degrees C and 65% relative humidity. I...

Background: Many common cancers, such as prostate, breast, and colon, are caused by harmful substances and compounds contained in processed foods, including nitrite-treated meats. The aim of this study was to investigate the possibility of replacing sodium nitrite with Monascus purpureus pigment in sausage and to assess its antimicrobial, antioxidant, color, and sensory properties. Methods: The...

This article presents the development of green and sustainable mortars using alkali-activated high-calcium fly ash (AAFA) recycled glass (RG) as part fine aggregate. RG was used to replace river sand at dosages 0%, 25%, 50%, 75%, 100% by weight. Sodium hydroxide (SH) sodium silicate (SS) solutions were liquid alkaline activators in all mixtures. The AAFA samples prepared with different liquid-t...

Ochronosis or black joints disorder is a rare autosomal recessive disorder caused by deficiency of homogentisic acidoxidase. Orthopaedic manifestations are common and mostly involve spine and large joints such as knee and hip.Arthropathy is progressive and will eventually leads to arthroplasty. Not being familiar with this disorder might lead todevastating complications. We present a 57 year-ol...

Abstract The purpose of this study is to investigate the impact recycled aggregate (RA) and sea sand (SS) replacement on fly ash (FA) slag-based geopolymer concrete (GPC). An orthogonal array design employed obtain optimum mix proportions, mixes are prepared using slag percentages 10%, 20%, 30% in FA/slag-based GPC. Sodium hydroxide (NaOH) solution at three concentrations (8 mol/L, 12 16 mol/L)...

Cardiac automaticity is partly due to a diastolic sodium current. Possible mediators of this include tetrodotoxin-sensitive "fast" channels, cesium-sensitive time-dependent pacemaker current channels, calcium-gated nonspecific channels, and electrogenic sodium-calcium exchange. We have studied the effects of abrupt sodium removal on membrane current and conductance in voltage-clamped chick embr...

A 34 year old man, registered disabled as a result of muscle weakness, was admitted to hospital because of increasing weakness. He had profound hypokalaemia and admitted to taking up to 1400 ml of kaolin and morphine mixture daily. After considerable potassium replacement muscle power recovered completely. The hypokalaemia is likely to have been caused by the combination of liquorice extract an...
