Environmental influence on blood serum detection using ultraviolet 365

چکیده
The major use of alternative light sources (ALS) in the evaluation bloodstains has been primarily focused on detection whole blood, with relatively little attention to visualization blood serum. Serum may become separated from pools during clotting, and because it is invisible certain backgrounds, go undetected by a perpetrator attempting clean up crime scene. Recently, Ultraviolet 365 (UV 365) was shown be an effective tool evaluation, useful for even minute quantities Here effects environmental conditions serum stain appearance were evaluated, including temperature, pH, protease sensitivity, solubility, aging. Interestingly, found that UV fluorescence increases upon exposure heat, which accompanied color changes under visible decreased solubility multiple solvents. efficiency stains somewhat variable, depending type material dried. Finally, current study documents effect heating formation fluorescent halo rings dried bloodstains. Taken together, these data demonstrate affected influence its both light.

Electrochemical Detection of Insulin in Blood serum using Ppy/GF Nanocomposite Modified Pencil Graphite Electrode
In this study, pencil graphite electrode was modified using conductive polypyrrole (Ppy) and grapheme (GF) nanocomposite for electrochemical determination of insulin. Electrochemical behavior of insulin on PGE was investigated using cyclic voltammetric (CV) and differential pulse voltammetric (DPV) and chronoaprometry (CA) methods. Several effective parameters including pH, concentration, and s...

Introduction: Electrocution is the cause of many deaths in the world annually, that electric current passing between the body and earth can be the reason; thus, it is of great importance to construct the ground protection system using earth pit. This study aimed to investigate the effective environmental conditions on the earthchr('39')s pit resistance using the simulation method. Materials an...
متن کاملAnalysis on Heat Coagulated Blood and Serum. Iv. Direct Determination of Uric Acid by Ultraviolet Absorption.
A direct ultraviolet absorption method that does not require uricase for the determination of serum urate is presented. Serum (0.3 ml.) is placed in the bottom of a 25 X 95-mm. shell vial and coagulated by immersion of the vial in boiling water for 2 mm. The clot is overlaid with 3.0 ml. of water and the serum urate extracted for 60 mm. at 37#{176}. The absorbance of the extract is measured at ...

PURPOSE To determine the effect of riboflavin/ultraviolet-A (365 nm) corneal collagen cross-linking on the transmission of the ultraviolet-visible (UV-VIS) light spectrum through the cornea. METHODS Twelve New Zealand white male rabbits were used in this research. Cross-linking was performed unilaterally on the right eyes of the animals while only the epithelium was removed on the left eyes a...
