Journal of Agricultural and Food Chemistry. 63, 745−753. DOI: 10.1021/jf5046415. This article talks about the simplicity, stability and sensitivity of conventional lateral flow immunoassay (LFI) device for the use of detecting foodborne pathogens. Foodborne pathogen has prevailed to cause disease…

Chapter 2 (Cadmium) NG Ka Yan 2.1 Introduction Cadmium(Cd) is toxic which can affect human health at low levels, and it is a carcinogen. Cd cause cancer which is lung, kidney and prostate cancer. Cd leads cancer because of the oxidative stress. Oxidative stress involved the Cd-induced aberrant gene expression, apoptosis and inhibit the DNA damage repair. Besides, Cd trigger the reactive oxygen species (ROS) formations by producing cellular thiol redox imbalance, and that make intracellular…

along with the optimized method. 3) Wavelength: It can be determined by changing the wavelength. The standard solution of Decitabine was prepared and was injected by changing anwavelength along with the optimized method. LOD and LOQ[17] Limit of detection (LOD) and limit of quantification (LOQ) of Decitabine was calculated from the calibration curve method. The linearity solutions of Decitabine were prepared and injected. LOD and LOQ were calculated by using following…

major role in electrochemical research. It has been diligently used for the interpretation of corrosion mechanisms and in the characterisation of charge transport over the membrane. In the area of biosensors, it is especially appropriate for the detection of binding events on the transducer surface. In this report a short prologue to the measuring principles of electrochemical impedance spectroscopy could be furnished, followed by an outline of the utilization of the procedure in the discipline…

3-second mean hug duration is plausible since this value falls within the 95% confidence interval. Since it falls between the two limits, there is a 95% chance of the length hug occurring in each relationship group. Coach/Athlete: Lower limit= 3.77-2(.451)=2.87 and Upper limit = 3.77+2(.451)=4.67 2.87 < µ < 4.67 Supporter/Athlete: Lower limit= 3.16-2(.319)=2.52 and Upper limit = 3.16+2(.319)=3.80 3.16 < µ < 3.80 Problem 5.31 The figure provided in problem 5.31, shows the…

What is the photon detection efficiency (PDE) of a SiPM? Photon detection efficiency (PDE) refers to the probability that a photon arriving on the SiPM surface is detected, an initiates the process of current pulse generation. PDE is a function of the overvoltage ΔV across the terminals of the APD and wavelength λ of the incident photon. Photon detection efficiency is one of the most important characteristics of a SiPM. PDE is the product of three factors :- Geometrical fill factor (FF), Quantum…

The detection limit (LOD) may be expressed as LOD = 3.3 e) Quantitation Limit The Quantitation limit of an analytical procedure is the lowest amount of analyte in a sample, which can be quantitatively determined with suitable precision and accuracy. Quantitation Limit (LOD) may be expressed as LOQ = 10 S Where =…

sample was used). You can then compare this with the stated amount of drug in the same amount of millilitres. A percentage can then be calculated to see how near to 100% the drug in the sample is. It can then be decided whether the drug is within the limits to pass or not. 5. An advantage for HPLC is that it is a very precise technique and it will give qualitative and quantitative results. TLC, on the other hand, is very unreliable and will only give qualitative results. HPLC has a significant…

virtue of the pulse height distribution and establishing detection window threshold within the detection unit. As discussed earlier, it is possible to establish a lower threshold limit that eliminates pulses from background and noise. In addition establishing an upper threshold would determine a region where the majority of the beta pulses will be detected. This region will be identified at the Beta (βo) window. The dotted lines are the detection…

According to Garcia, Harden, and Chapman (2012), renal transplants improve both the lifetime expectancy and quality of life for the patient. The transplants are also the most cost effective solution. The only thing that limits the procedure is the supply, since the procedure makes use of another human kidney (Saeb-Parsy & Watson, 2011). The risks associated with renal transplantation are primarily during the operation, and directly after the operation when seeing if the…
