This study investigated the optimization of bioconcrete engineering properties and durability as a response calcium lactate (CL) content (0.22–2.18 g/L) curing duration (7–28 days) using surface methodology (RSM). Scanning electronic microscopy (SEM) was conducted to evaluate microstructure precipitated inside bioconcrete. The results indicated that optimal conditions for concrete were determin...

Sewage sludge ash (SSA) as a secondary phosphorus (P) source may help to conserve global rock phosphate deposits if used in the base fertilization of soilless growing media. Plant availability SSA-P was studied pot experiment with marigolds peat-based medium contrasting pH (4.5, 6.0). Six SSAs were included study and compared water-soluble monocalcium (MCP) (RockP). In addition efficacy SSA-P, ...

Metabolic acidosis correction is one of the goals of renal replacement therapy. Correction of acidosis in peritoneal dialysis (PD) may be affected by PD modalities such as automated PD (APD) or by new solutions containing a combination of bicarbonate and lactate as a buffer [bicarbonate continuous ambulatory PD (CAPD)]. The aim of the present study was to examine the acid-base status of our PD ...

In patients with cystic fibrosis who do not produce sputum, deep throat swabs are cultured for potential respiratory pathogens. Usually these swabs are directly streaked onto selective agar media. In a study of 50 pediatric cystic fibrosis patients, we compared this traditional method using rayon swabs with two methods having quantitative modifications: calcium alginate swabs eluted in Ringer's...

The effect of 12 h transport on the biochemical and haematological profiles of three-years-old common carp was investigated. There was a significant increase (P < 0.01) in ammonia, chloride, phosphorus, lactate dehydrogenase, aspartate aminotransferase and creatine kinase, and a significant decrease (P < 0.05) in total proteins. The levels of glucose (P < 0.01), lactate (P < 0.05), alanine amin...

Vascular smooth muscle cells from rabbit arteries were grown in tissue culture and stimulated by DC impulses (1 mA, 1 V, 10 Hz, 1 ms/imp). Scanning microscopic examination disclosed that in stimulated cultures the cell surface was enlarged by numerous microvilli. This was interpreted as being indicative of an increase in cell activity. Cellular metabolism was character­ ized by analyzing the in...
