The sequential fluorination-alkaline treatment protocol has been applied for the tailoring of siliceous ZSM-5 zeolite. original spontaneous growth mesoporosity in alkaline medium is altered due to antecedent fluorination step. outcome demonstrated by apparent delay growth, whose essential duration well-defined therefore extended from 30 min 60 min. A low level decelerates whereas a high enables...

from nontuberculous effusions by measuring pleural adenosine deaminase (ADA),4’ lysozyme (LZ),6 and interferon-gamma (IFG)7; these biochemical compounds are elevated in tuberculous effusions depending on the size of the effusion, although there is an overlap in the pleural concentrations of ADA and LZ.3 We reasoned that the pleural alkaline phosphatase concentration would be a useful means of d...

OBJECTIVES To assess the efficacy of a single intravenous infusion of pamidronate in Paget's disease of bone. METHODS Fourteen patients with active Paget's disease (raised serum alkaline phosphatase, bone pain or neurological involvement) were treated with a single intravenous infusion of 105 mg pamidronate. Patients were assessed for biochemical and clinical improvement for up to two years f...

In the Baltic Sea, peptidase and alkaline phosphatase activities always show the same pattern in nutrient gradients: increasing enzyme activities with decreasing dissolved inorganic nitrogen (DIN) and phosphate. The field experiments reported here suggest that peptidase activity may be regulated by DIN in a manner similar to that of alkaline phosphatase by phosphate. In nutrient gradients estab...

22 23 The Comet assay was performed on mouse and human spermatozoa to 24 examine the effect of alkaline DNA unwinding time. The spermatozoa were 25 treated in vitro with the DNA-damaging agents, methyl methanesulfonate 26 (MMS) or hydrogen peroxide (H2O2), and then embedded in agarose gel on 27 glass slides. The slides were immersed in alkaline solution (> pH 13) for 1, 5, 28 10, and 20 min, an...

Alkaline phosphatase is normally localized to the periplasm of Escherichia coli and is unable to fold into its native conformation if retained in the cytoplasm of growing cells. The alkaline phosphatase activity of E. coli expressing a version of the protein without a signal sequence was nonetheless found to increase gradually when the growth of cells was suspended. At least 30% of the protein ...

Banana fiber (BF) is a renewable resource which can be good reinforcer to polylactic acid, enhancing the polymers stiffness and accelerating biodegradability rates. However, due difference in nature between banana fibers (hydrophilic) acid (hydrophobic), adhesion matrix cannot achieved. To tackle problem, were chemically treated using sodium hydroxide under three factors (temperature, concentra...

As part of a program to reduce electrical energy consumption in the refining process, the effects of the ozone and alkaline peroxide treatments on fibre and handsheet properties, prior and subsequent to low consistency (LC) refining, were assessed and compared by applying different levels of ozone and a range of peroxide and alkali charges to a primary stage hemlock thermomechanical pulp (TMP)....
