[Q]: Here we describe a novel endonuclease IV (Endo IV) based assay utilizing a substrate that mimics the abasic lesions that normally occur in doublestranded DNA. The three component substrate is characterized by single-stranded DNA target, an oligonucleotide probe, separated from a helper oligonucleotide by a one base gap. The oligonucleotide probe contains a non-fluorescent quencher at the 5 0 end and fluorophore attached to the 3 0 end through a special rigid linker. Fluorescence of the oligonucleotide probe is efficiently quenched by the interaction of terminal dye and quencher when not hybridized. Upon hybridization of the oligonucleotide probe and helper probe to their complementary target, the phosphodiester linkage between the rigid linker and the 3 0 end of the probe is efficiently cleaved, generating a fluorescent signal. In this study, the use of the Endo IV assay as a post-PCR amplification detection system is demonstrated. High sensitivity and specificity are illustrated using single nucleotide polymorphism detection.

[Q]: Microbes have made a phenomenal contribution to the health and well-being of people throughout the world. In addition to producing many primary metabolites, such as amino acids, vitamins and nucleotides, they are capable of making secondary metabolites, which constitute half of the pharmaceuticals on the market today and provide agriculture with many essential products. This review centers on these beneficial secondary metabolites, the discovery of which goes back 80 years to the time when penicillin was discovered by Alexander Fleming.

[Q]: Lack of a proper assessment method on performance risks in Energy Performance Contracting (EPC) projects is one of the reasons hindering the further development of energy service companies (ESCOs) market. This paper proposes a simulation-based method to evaluate the probability of energy saving shortfall taking into account the variations in the influential parameters, including weather conditions, occupancy, operating hours, thermostat set-point, etc., during the contract period. The proposed method involves the use of a detailed building energy simulation programme, sensitivity analysis and Monte Carlo simulation techniques. Empirical data is also used to develop the probability distribution functions for the identified parameters to simulate the actual yearly variations in the post-retrofit conditions. A real case study of replacement of heat rejection system for a central chiller plant in Hong Kong is used to demonstrate the application of this probabilistic method. The result shows that the possible energy savings after a 1-year retrofit period ranges from 393,000 kW h (2.86%) to 1098,000 kW h (10.8%) with 90% statistical significance.
