Protective effect of co-enzyme Q10 on testicular tissue and sperm parameters in adult male rats treated with Sunset Yellow FCF

Objective:To determine the protective effect of co-enzyme Q10(CoQ10)on testicular tissue and sperm parameters in male rats treated with SunsetYellow FCF.Methods:Sixty male Sprague-Dawley rats were randomly divided into 6 groups of the control,CoQ10(10 mg/kg/day),low dose of Sunset Yellow(2.5 mg/kg),high dose of Sunset Yellow(70 mg/kg),low dose of Sunset Yellow(2.5 mg/kg)plus CoQ10,and high dose of Sunset Yellow(70 mg/kg)plus CoQ10.The drugs were administered via daily oral gavages for 6 weeks.At the end of the experiment,sperm analysis,stereological and histological assessments of the testis were carried out.Results:The normal morphology(by 41.1%)and progressive spermatozoa(by 74.8%),testicle volume(by 33.4%),lumen volume(by 38.3%),interstitial tissue volume(by 44.7%),seminiferous tubule volume(by 40.7%),and number of spermatogonia(by 53.9%)and Leydig cells(by 70.7%)reduced in the rats that received high doses of Sunset Yellow in comparison to the control group.Nonetheless,all these alterations were recovered by CoQ10 treatment in the CoQ10 plus high dose of Sunset Yellow group.Furthermore,low doses of Sunset Yellow did not affect different parameters of the testis and sperm.Conclusions:CoQ10 could,to some extent,prevent structural changes of the testis induced by the high dose of SunsetYellow.

The Construction of Community Under the Subprime Crisis in Sunset Park

In Sunset Park,the contemporary American writer Paul Auster reveals the political,economic and social problems that have surfaced in America in the wake of the 9/11 incident.Focusing on the image of people on the edge of the city,the author describes how they rebuild their lives after illegally living in an abandoned apartment in Sunset Park,using the art and the community as a spiritual refuge to seek comfort and heal wounds,reconstruct self-identity,and fight against the unfair society.This article analyzes the characteristics of the community in the novel Sunset Park,to interpret its functions,and to show the healing power of a caring community.

Simultaneous Determination by HPLC-UV Vis of Tartrazine and Sunset Yellow in Soft Drinks Sold in Benin

The use of dyes such as tartrazine (E102) and sunset yellow (E102) in food, beverages and health products for technological and commercial purposes is common. The adverse effects caused by these dyes, such as allergies and hyperactivity disorder have been reported, especially in children. In the present study, a chromatographic method was developed and validated for simultaneous determination of tartrazine and sunset yellow. The chromatographic separation was performed on a Lichrocart® C18 column (125 × 4.6 mm;5 μm) with a security Guard-C18 column (4 × 2.0 mm, 5 μm;Phenomenex, Torrance, CA, USA) maintained at 30°C. The mobile phase consisted of a mixture of acetonitrile/ammonium acetate buffer pH 6.8 in gradient mode with a flow rate of 1 mL/min. The injection volume was 10 μL. The detection wavelength was set at 455 nm. The parameters of specificity, linearity, precision, repeatability, accuracy and sensitivity were examined for validation. The developed method is linear in the range of 1 μg/mL to 100 μg/mL with a R2> 0.998. The intra-day and inter-day precisions (RSD) were less than 0.6% and 3.1% respectively. The detection limit was 0.03 μg/mL and the quantification limit was 0.1 μg/mL. The retention time of tartrazine was 2.86 min, while sunset yellow was detected at 5.67 min. A simple, rapid, accurate and robust HPLC/UV-Visible method was developed and validated for simultaneous identification and quantification of tartrazine and sunset yellow. This developed method was successfully applied for the simultaneous determination of tartrazine and sunset yellow in soft drinks sold in Benin.

Extraction Method and Determination of Sudan I Present in Sunset Yellow FCF by Isocratic High-Performance Liquid Chromatography

A method to extract and analyze Sudan I present in Sunset Yellow FCF (SYF) products was developed and validated. The method included the simple extraction of Sudan I from the SYF product using water, acetonitrile, and ethyl acetate and high-performance liquid chromatography (HPLC) analysis with isocratic elution using acetonitrile:water (7:3) with a photodiode array detector at 485 nm. This method was found to remove most of the excess SYF colorant and other impurities before injection to the HPLC instrument, making it easy to maintain precision control in routine laboratory tests for Sudan I in the SYF colorant. The detection limit of Sudan I in SYF products was 0.2 μg/g. A survey conducted to determine Sudan I in 13 commercial SYF samples from Japanese manufacturers from 1970 to 2010 showed that the levels of Sudan I ranged from 0.3 to 1.9 μg/g in products manufactured from 1970 to 1996 and were below the limit of detection in products manufactured after 2005.

An Amperometric Sensor for Sunset Yellow FCF Detection Based on Molecularly Imprinted Polypyrrole

An electrochemical method for fast detecting the concentration of sunset yellow FCF in wine samples was developed in this study. The sensor based on imprinted films which fabricated by electropolymerization of pyrrole on a glassy carbon electrode in the presence of sunset yellow FCF as the template. Comparing to the polypyrrole non-imprinted modified (NIP) electrode, the polypyrrole molecularly imprinted polymer (MIP) electrode improved the electrochemical performance of the sensor significantly. The peak current at about 0.26 V was linear with the concentration of sunset yellow FCF from 0.4 to 2 μM and from 2 to 8 μM. It can be used for more than 10 times to maintain a stable response result. The sensor had the good selectivity on sunset yellow FCF, amaranth and tartrazine, which the selection factors were 1.00, 0.80 and 0.85,respectively.

Preparation of Activated Carbon Based on Straw and Its Adsorption on Sunset Yellow

The removal effect of sunset yellow by the activated carbon prepared by modified straw was studied, and the effects of adsorption temperature, adsorption time, adsorption capacity, solution salinity and solution pH on the removal effect of sunset yellow were analyzed. After being soaked in acid and alkali, the stalks and leaves of the straw were carbonized and modified at 200-700 ℃. The results show that the adsorption effect of the leaves soaked in alkali was the best when the carbonization temperature was 700 ℃. As the adsorption temperature was 30-40 ℃, the adsorption effect of sunset yellow was the best. With the increase of adsorption time, the removal rate of sunset yellow first increased, then decreased, and finally rose again. The first critical point was about 30 min. When the dosage of activated carbon was 0.7 g, the adsorption effect of 50 ml of sunset yellow solution was the best. The optimal solution salinity was 60%. pH had a small effect on the adsorption of sunset yellow, showing a fluctuating trend.

论刘长卿的夕阳书写及其诗史影响

刘长卿诗歌中有大量关于夕阳的描写。他常以素笔,简练书写个人经历和社会现实,突出了其夕阳书写平淡自然的创作风格;此外,他的夕阳书写以五言居多,诗中的意象多呈现出清空淡远的面貌。他在夕阳诗中展现了其坎坷人生下的隐逸之思,表达了自己两遭贬谪、漂泊在外的羁旅愁思;同时,又强调了其对人生短暂、时光流逝的生命意识的感慨。刘长卿的夕阳书写既是对魏晋盛唐诗人的接受与新变,又对晚唐夕阳书写产生了深远的价值。
