Introduction: Contamination of pistachio nuts of Aspergillus species and their toxins is the most serious health threat for human and animal. Sorting out contaminated pistachios is critical to reduce the sources and levels of aflatoxins in pistachio nuts. Distribution of aflatoxin in processed pistachios was determined in the fifth and twentieth of September and fifth of October. Methods: Samp...
The Bartels respiratory virus panel detection kit is an indirect fluorescent-antibody (IFA) method that uses pooled and individual antisera for tissue culture confirmation of seven respiratory viruses. We evaluated these reagents for detecting viral antigen in shell vial cultures and by direct staining of cells from respiratory specimens. The isolation from 254 specimens of respiratory viruses ...
Avian eggshells are variable in appearance, including coloration. Here, we demonstrate that Raman spectroscopy can provide accurate diagnostic information about major eggshell constituents, including the pigments biliverdin and protoporphyrin IX. Eggshells pigmented with biliverdin showed a series of pigment-diagnostic Raman peaks under 785 nm excitation. Eggshells pigmented with protoporphyrin...
objective: prostate cancer is the second most common cancer worldwide. chemotherapeutic agents have been shown to have adverse side-effects, and natural compounds have been recommended for cancer treatment, nowadays. crab shell has been shown to have cancer preventative and suppressive effects in vivo and in vitro. the aim of present study was to investigate the effect of crab shell extract on ...
As typical biofoulers, barnacles possess hard shells and cause serious biofouling problems. In this study, we analyzed the protein component of the barnacle Amphibalanus (= Balanus) amphitrite shell using gel-based proteomics. The results revealed 52 proteins in the A. Amphitrite shell. Among them, 40 proteins were categorized into 11 functional groups based on KOG database, and the remaining 1...
Loss of shell colour in brown-egg layers is a shell quality issue in Australia and is periodically associated with free range egg production. This study investigated the loss of shell colour that occurs in some flocks of free range laying hens. Hens laying pale-coloured egg shells on a commercial free range farm were transferred to cages in an experimental facility. Egg quality was measured imm...
Age validation is the first step to determine shellfish species age determination. This information is vital for different inferential models used in marine ecosystem management activities. In spite that various validation techniques are used for marking carbon calcium structures, the calcein marking technique for oysters had never been used for age validation in Pinctada mazatlanica. Thus the ...
In this study, we analyzed the combined effect of microalgal concentration and temperature on the shell growth of the bivalve Pinctada margaritifera and the molecular mechanisms underlying this biomineralization process. Shell growth was measured after two months of rearing in experimental conditions, using calcein staining of the calcified structures. Molecular mechanisms were studied though t...
In order to improve the technology of cocoon processing, create waste-free technologies, a surface activator was synthesized on basis bardo residue fraction and lubricating oils formed during production ethyl alcohol. Based IR-spectral analysis, presence hydroxyl carboxyl groups in surfactants determined be suitable raw material for surfactants, substance from it can used staining. IR-spectrum ...
Immunofluorescence staining of centrifugation-enhanced shell vial (SV) cultures for respiratory viruses (RV) after 24 h of incubation, rather than the more commonly prescribed times of 48 h and 5 days, allowed for the detection of 77% of the RV-positive specimens that would ordinarily not have been detected as positive until 48 h. Staining SVs at 24 h also permitted earlier detection of viruses...
