Abstract
BACKGROUND Breast cancer (BC) is the most common cancer among women worldwide. We conducted a systematic review and meta-analysis to cover the existing research gap and contribute to existing knowledge to provide both researchers and clinicians with a better profile on the topic and consequently help improve the quality of life (QoL) of patients with BC. METHODS A comprehensive review of original articles published in English from January 2000 to October 2021 from databases including Embase, Scopus, PubMed and Web of Science was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS Based on the meta-regression which examined a total of 9012 patients with BC, the QoL score calculated by EORTC QLQ-C30 was 64.72 (95% CI 59.24 to 70.20), while the score obtained from FACT-B was 84.39 (95% CI 64.24 to 104.54) and the scores from QLQ-BR23 and SF-36 were 66.33 (95% CI 62.76 to 69.90) and 57.23 (95% CI 47.65 to 66.82), respectively. A meta-analysis affirmed a significant direct relationship between the QoL score of patients with BC and their age (p=0.03). The results also revealed that the QoL scores of patients who had completed treatment were higher than those who were currently under treatment. CONCLUSION The present systematic review identified several factors that affect the QoL of women with BC worldwide and provided several implications for developing policy interventions to effectively improve the QoL of women with BC. In this way, clinicians can sufficiently give advice to their patients with the purpose of improving their QoL. PROSPERO registration number CRD42022309791.

Abstract
Background Consensus guidelines on the therapeutic drug monitoring of vancomycin published in 2020 recognize that using the calculated area-under-the-curve (AUC) to guide dosing maximizes clinical efficacy and minimizes risk when compared to traditional trough-based dosing. The purpose of this study was to determine whether AUC monitoring results in reduced acute kidney injury (AKI) rates in adult patients receiving vancomycin for all indications. Methods In this study, patients 18 years or older who received pharmacist-managed vancomycin therapy were selected using pharmacy surveillance software from 2 timeframes. Patients were excluded if they received less than 48 hours of therapy or had unstable renal function or hemodialysis at baseline. The primary outcome measured was the incidence of AKI in each group of patients. Results Data were collected for 121 patients in each group. Concomitant nephrotoxins used in each group, as well as the sources of infection, were similar between groups. AUC monitoring did not result in a significant decrease in AKI rate (16.5% in AUC group, 14.9% in trough group; P = .61). However, patients who received AUC monitoring were more likely to be therapeutic at first follow-up compared to the trough monitoring group (43.2% in AUC group, 33.9% in trough group; P = .03). AUC monitoring also resulted in lower trough levels and total daily doses, with no difference in mortality or length of stay. Conclusion AUC monitoring did not result in an observed decrease in AKI rate. Despite this, the AUC monitoring protocol was effective at reaching the goal AUC of 400-600 mg*hour/L and did not increase mortality or length of stay.

Abstract
Background Parkinson's disease can adversely affect the quality-of-life. Aims We conducted a systematic review and meta-analysis of global literature on the quality-of-life of patients with Parkinson's disease and examined the association between patient characteristics and quality-of-life. Methods We searched Embase, PubMed, Scopus and Web of Science from January 2000 to January 2020. We included articles published in English that used the Parkinson's disease questionnaire to estimate the quality-of-life score and to identify the determinants of quality-of-life in patients with Parkinson's disease. Results In total, 41 studies with data from 4060 patients who had Parkinson's disease met our inclusion criteria. The overall quality-of-life score was 32.37 (95% confidence intervals (CI): 28.72-36.01). Age and duration of disease were inversely related to quality-of-life (P < 0.001). South America had the highest score on the questionnaire (39.73, 95% CI: 28.66-50.79, P < 0.001), indicating the lowest quality-of-life of patients with Parkinson's disease. Of the 6 World Health Organization regions, the Eastern Mediterranean Region had the highest score (36.28, 95% CI: 23.44-49.13, P < 0.001). Conclusion Although the global score in patients with Parkinson's disease indicated an acceptable quality-of-life, there is a possibility for improvements. The findings of this study can inform evidence-based strategies by health policymakers and clinicians to enhance the quality-of-life of patients with Parkinson's disease.

Abstract
Coronary artery disease (CAD) exhibits the rules of the multifactorial hereditary. Notwithstanding, the role of genetic factors in the prevalence of CAD is estimated very high. SIRT1 plays an athero-protective role and alterations in its expression have some important consequence in the metabolism, cholesterol, and fat deposition. The aim of our study was to investigate the association between rs4746720, rs12413112, and rs1467568 polymorphisms in the SIRT1 gene and CAD in the high-risk cases. In the present retrospective case-control study, 150 healthy individuals and 150 cases diagnosed with atherosclerotic lesions were investigated. ARMS PCR was used to determine the genotypes of rs4746720 polymorphism, while tetra primer-ARMS PCR was used for genotyping of rs12413112 and rs1467568 polymorphisms. Considering rs12413112 polymorphism, the frequency of the AG heterozygote genotype was significantly lower in cases than controls (P < 0.001). Furthermore, the frequency of the A-positive (AA+AG vs. GG) genotype was significantly different between groups (P < 0.001). The frequency of the variant A allele was 0.36% in cases and 0.46% in controls (P = 0.01). Except for a borderline protective effect in the present of rs1467568AG genotype, the allele and genotype distributions of both rs1467568 and rs4746720 polymorphisms did not differ between two groups. The haplotype constructed from rs1467568A, rs12413112A, and rs4746720T alleles showed a significant protective effect on the risk of CAD (OR: 0.53; 95%CI: 0.35-0.78; P = 0.001). In conclusion, the SIRT1 gene may contribute to the pathogenesis of CAD, while further investigations were suggested to confirm our results.

Abstract
Net fluid flow of soap films induced by (ac or dc) electric fields in asymmetric frames is presented. Previous experiments of controllable soap film flow required the simultaneous use of an electrical current passing through the film and an external electric field or the use of nonuniform ac electric fields. Here a single voltage difference generates both the electrical current going through the film and the electric field that actuates on the charge induced on the film. The film is set into global motion due to the broken symmetry that appears by the use of asymmetric frames. If symmetric frames are used, the film flow is not steady but time dependent and irregular. Finally, we study numerically these film flows by employing the model of charge induction in ohmic liquids.

Abstract
The purpose of this study was to investigate the adsorption of uranium (VI) ions on the polypyrrole adsorbent. Polypyrrole was synthesized by a chemical method using polyethylene glycol, sodium dodecylbenzenesulfonate, and cetyltrimethylammonium bromide as the surfactant and iron (III) chloride as an oxidant in the aqueous solution. The effect of various surfactants on the synthesized polymers and their performance as the uranium adsorbent were investigated. Adsorbent properties were characterized by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) techniques. The effect of different parameters such as pH, contact time, initial metal ion concentrations, adsorbent dose, and the temperature was investigated in the batch system for uranium adsorption process. It has been illustrated that the adsorption equilibrium time is 7min. The results showed that the Freundlich model had the best agreement and the maximum adsorption capacity of polypyrrole for uranium (VI) was determined 87.72mg/g from Langmuir isotherm. In addition, the mentioned adsorption process was fast and the kinetic data were fitted to the Pseudo first and second order models. The adsorption kinetic data followed the pseudo-second-order kinetic model. Moreover, the thermodynamic parameters ΔG0, ΔH0 and ΔS0 showed that the uranium adsorption process by polypyrrole was endothermic and spontaneous.

Abstract
Fluid flow of suspended liquid films induced by non-uniform alternating electric fields has been reported. The electric fields were generated by two rod-like electrodes perpendicular to the fluid surface. The observed fluid flow was explained qualitatively by considering a charge induction mechanism, where the electric field actuates on the charge induced on the film surface. In this paper we perform a numerical study of this fluid flow taking into account the charge induction mechanism. The numerical results are compared with experiments and good agreement is found. Finally, we propose the application of the device as a new kind of two dimensional fluid pump.

SUBJECTS/METHODS This double-blinded, randomized and placebo-controlled trial was conducted on 56 male soccer players, with age range of 16-35, who referred to sport clubs in Isfahan, Iran. Subjects were randomly assigned to either l-arginine or placebo groups. Athletes received daily either 2 g per day l-arginine supplement or the same amount of placebo (maltodextrin) for 45 days. Sport performance and also body mass index (BMI), body fat mass (BFM) and lean body mass (LBM) were measured at the beginning and end of the study. Also, 3-day dietary records were collected at three different time points (before, in the middle of, and at the end of the study). RESULTS The mean age of subjects was 20.85±4.29 years. Sport performance (VO2 max) significantly increased in l-arginine supplementation group (4.12±6.07) compared with placebo group (1.23±3.36) (P=0.03). This increase remained significant even after adjustment of baseline values, physical activity and usual dietary intake of subjects throughout the study. No significant effect of l-arginine supplementation was found on weight, BMI, BFM and LBM. CONCLUSIONS l-arginine supplementation (2 g per day) could increase the sport performance in male athletes, but had no effect on anthropometric measurements, including BMI, BFM and LBM. So, further studies are needed to shed light our findings.

Abstract
In greenhouse experiment, the seed samples of 3 populations were treated with treatments including: cold stratification, Gibberlic Acid (50 ppm and 100 ppm), Potassium nitrate (0.2%, 0.4%), physical scarification (sand paper), chemical scarification (Ethylic alcohol 70%) and distilled water (control), then these treated seed samples were sown in pots as randomize design with three replication. The germination characteristics including: germination percentage, speed of germination, length of root and shoot, seedling length, ratio of root length by shoot length, vigor index, fresh weight arid dry weight, ratio of dry weight by fresh weight were evaluated during 45 days of experiment. Comparing between three populations of Sahandy savory, seed germination characteristics of the Ghazvin population was higher than the other two populations. According to effect of treatment on germination seed characteristics, the species of savory and their population, it was concluded that effect of Gibberlic Acid and Potassium nitrate was higher than physical scarification and chemical scarification comparing with control. With more effective of gibberlic acid and KNO3 and cold treatment on seed germination enhancement of the population, it was clarified that the type of dormancy of some population of Sahandy savory was physiological dormancy.

Abstract
BACKGROUND Chronic renal disease is a health problem in today's world. In the end-stages of renal disease patients depend upon alternative therapies including dialysis for their survival. However, dialysis causes several stressors on physical, mental and social performance of patients. The present study aimed to review and compare the self-concept in patients undergoing hemodialysis and peritoneal dialysis. MATERIALS AND METHODS This was a case-control study including two groups of patients, undergoing hemodialysis and peritoneal dialysis, who referred to Al-Zahra and Ali Asghar Hospitals, which are affiliated to Isfahan University of Medical Sciences. These groups were compared to the control group. Data were collected through completing the form of demographic characteristics and a questionnaire, written by the researcher, pertaining to the self-concept which was collected by the samples. The data were analyzed by the Software SPSS version 18. FINDINGS ANOVA (analysis of variance) showed that statistically there was a significant difference between mean score of self-concept in the three physical (body-image), psychological, and social self aspects in the two groups of hemodialysis and peritoneal dialysis with the control group; however, Duncan's post-hoc analysis showed no significant difference between mean score of self-concept in the three mentioned aspects in the two groups of hemodialysis and peritoneal dialysis. Furthermore, ANOVA (analysis of variance) showed that there was no significant difference between mean score of the spiritual aspect of the self-concept in the two groups of hemodialysis and peritoneal dialysis with the control group. Duncan's post-hoc analysis also showed no significant difference in this aspect between the two groups of hemodialysis and peritoneal dialysis. CONCLUSIONS Patients undergoing dialysis have many psychological disorders and the type of dialysis is not of much importance in this regard; therefore, adequate education and information for clients in order to use appropriate methods of adaptation as well as appropriate social relationship, continuing social support and developing health policies seem necessary in order to prevent mental disorders and providing required services and supports for patients.

Abstract
BACKGROUND These days, diabetes is deemed as one of the most important health and social-economic problems of the world. Since parents play a major role in treatment of diabetes, the most important part of managing diabetes is in the hands of the parents of children affected by diabetes. This special responsibility will increase the stress and family challenges and impacts parents' emotional responses. The affective reactions or responses of the parents can also be conveyed to the child himself and reduce self-care, increase glucose levels, increase the possibility of complications and reduce the quality of life. Thus, it is highly important to recognize the affective reactions of parents during various stages of the disease for the purpose of intervention. MATERIALS AND METHODS All parents of children diagnosed with insulin-dependent diabetes who referred to Sedigheh-ye-Tahereh Endocrinology and Metabolism Research Center, Isfahan, Iran, were selected and the Symptom Checklist-90 (SCL-90) was filled in five stages (immediately, one month, three months, six months and twelve months after diagnosis). Convenient sampling was used to select 45 consecutive subjects out of whom 10 dropped out during the study. FINDINGS The major problems of the study subjects at the beginning of diagnosis were depression, anxiety and physical problems, respectively. Three, six and twelve months later, they were depression, obsession and physical problems. Over time, the mean score of parents' affective reactions declined which indicated the acceptance of the disease by parents over time. CONCLUSIONS In view of the fact that both mother and father of children with diabetes suffer from affective problems and since fathers refer to diabetes centers less than mothers, some decisions should be made to mentally support both fathers and mothers.

Abstract
BACKGROUND Von Willebrand disease (VWD) is an autosomal recessive congenital bleeding disorder with deficiency or dysfunction of von Willebrand factor (VWF). The gene encoding for the VWF is located on chromosome 12, which is 178 Kb with 52 exons. Various mutations of this gene is responsible for the clinical features of VWD, but some single nucleotide polymorphisms make the molecular diagnosis of it very complicated.In this study genetic variations in two exons (45 & 16) of VWF gene in Iranian patients suffer from type 3 VWD from south west of Iran were evaluated. MATERIALS AND METHODS Genetic variations in exon 45 and exon 16 of VWF gene were evaluated in 33 patients diagnosed with type 3 VWD from south west of Iran. Two exons with their flanking introns were amplified by PCR and amplicons were analyzed by sequencing for any molecular changes. RESULTS No mutation was found in both selected regions. An A/C polymorphism in intron 44 was recognized in all patients in homozygous manner. This SNP reported for the first time from Iranian VWD patients. CONCLUSION Mutation of VWF gene is different in various ethnic groups, which finding of is important in the diagnosis of the VWD, especially for prenatal diagnosis. A few mutations are reported for exon 45 and 16 of this gene in Iran and other countries. But, present study didn't find any mutation in these patients. Mutation in other exons or introns should be evaluated in affected individuals from south west of Iran.

Abstract
BACKGROUND Obesity has been associated with increased mortality from hormone dependant cancers such as breast cancer which is the most prevalent cancer in women. The link between obesity and breast cancer can be attributed to excess estrogen produced through aromatization in adipose tissue. The role of steroid hormone receptors in breast cancer development is well studied but how obesity can affect the expression pattern of steroid hormones in patients with different grades of breast cancer was the aim of this study. METHODS In this case-control study, 70 women with breast cancer participated with different grades of obesity (36 none obese, BMI < 25 kg/m(2) and 34 obese, BMI ≥ 25 kg/m(2)). The mean age of participants was 44.53 ± 1.79 yr (21-70 yr). The serum level of estrogen, progesterone and androgen determined by ELISA. Following quantitative expression of steroid hormone receptors mRNA in tumor tissues evaluated by Real-time PCR. Patients with previous history of radiotherapy or chemotherapy were excluded. SPSS 16 was used for data analysis and P < 0.05 considered statistically significant. RESULTS The difference in ERα, ERβ and PR mRNA level between normal and obese patients was significant (P < 0.001). In addition, the expression of AR mRNA was found to be higher than other steroid receptors. There was no significant relation between ERβ gene expression in two groups (P = 0.68). We observed a significant relationship between ERα and AR mRNA with tumor stage and tumor grade, respectively (P = 0.023, P = 0.015). CONCLUSION According to the obtained results, it is speculated that obesity could paly a significant role in estrogen receptors gene expression and also could affect progression and proliferation of breast cancer cells.

Abstract
Natural killer (NK) cells eliminate infected and transformed cells while still are self-tolerant. Interactions of the independently segregating Killer cell immunoglobulin-like receptors (KIR) and human leucocyte antigens (HLA) loci play a critical role in NK cell regulation. Different compound KIR-HLA genotypes can impart different thresholds of activation to the NK-cell repertoire and such genotypic variation has been found to confer altered risk in a number of human diseases including viral infections, autoimmune disorders, reproduction abnormalities and cancers. In this study, we presented a novel combined KIR-HLA polymerase chain reaction-sequence-specific primers genotyping assay for simultaneous determination of KIR genes and their three major HLA class I ligand groups (C1, C2, and Bw4). Moreover, known inhibitory and activating KIR + HLA (iKIR + HLA: 2DL2/3 + C1, 2DL1 + C2, 3DL1 + Bw4; and aKIR + HLA: 2DS2 + C1, 2DS1 + C2, 3DS1 + Bw4) combinations as well as co-inheritance of aKIR genes and iKIR + HLA pairs were analysed in a total of 200 unrelated healthy Iranian individuals. All tested subjects had at least one of the three iKIR + HLA pairs and the frequencies of various inhibitory combinations in the study group were: 31.5%, three iKIR + HLA pairs, 53.5%, two iKIR + HLA pairs, and 15%, 0ne iKIR + HLA pair. Furthermore, we revealed that majority of Iranians (69%) carry compound genotypes with greater number of inhibitory pairings than activating combinations (iKIR + HLA > aKIR + HLA). Conversely, iKIR + HLA < aKIR (45%) was dominant genotype in the study group. We conclude that selective evolutionary pressure has propensity to maintain KIR-HLA genotypes with more inhibitory combinations to guarantee self-tolerance. In contrast, existence of activating KIR genes without normal endogenous ligands, potentially arms the NK population for competent immunosurveillance and stronger defense against infections.

Abstract
Free radical suspension copolymerization of styrene (St) with methyl methacrylate (MMA) in the presence of n-pentane was investigated. The batch polymerization was performed in a stirred reactor via a two-stage process. First, free radical suspension polymerization of St and MMA in aqueous media was carried out at about 80—90°C with the aid of a monofunctional initiator to the monomer conversions up to about 70%. Second process, called impregnation stage, consisted of a high temperature—high pressure cycle (110—120°C and 10 bars) in which the blowing agent was charged in the reactor and polymerization was carried out with the aid of a high temperature initiator. Fine particles of micron sizes of St/MMA copolymer were synthesized by manipulation of some experimental parameters governing the copolymerization system. Polymerization was carried out at different agitation rates, suspending agent and aqueous phase initiator concentrations as well as emulsifier amounts, while keeping constant the MMA/St ratio. To reach a desired bead size, the above parameters were optimized using the Taguchi method for experimental design and the relative importance of the mentioned parameters was analyzed. Particles with a spherical shape of 250—350 μm were formed. The obtained copolymers were also characterized in terms of molecular weight, polydispersity index, copolymer composition, morphology of the polymer beads, thermal behavior, and particle size and particle size distribution.

Abstract
INTRODUCTION Subjective health perceptions affect sexual function differently in males and females; such differences, however, have not hitherto been studied comprehensively in kidney-transplant recipients. AIM This study sought to investigate gender effect on the correlation between sexual function and quality-of-life (QOL) subdomains in kidney-transplant recipients by evaluating intercourse frequency (IF) and intercourse satisfaction (IS). METHODS In a cross-sectional study, 124 married kidney-transplant recipients, who were randomly selected, were interviewed. The bivariate correlations between QOL subdomains, and IF and IS were analyzed with the Pearson test in the males and females, separately. MAIN OUTCOME MEASURE The IF and IS using the relationship and sexuality scale, and also the QOL using Short Form 36 (SF-36) were assessed. RESULTS Sixty-seven subjects (54%) reported having no intercourse within the preceding months. Fifty subjects (40%) reported having no intercourse satisfaction. While IF and IS correlated with the total SF-36 score in the males (r = 0.252 and 0.263, P < 0.05), there was no such correlation in the females. In the males, IS correlated with physical health (r = 0.281, P < 0.05) and physical function (r = 0.274, P < 0.05), and there was a correlation between IF and role limitation due to emotional problems (r = 0.250, P < 0.05). In the females, whereas IF correlated with general health (r = 0.372, P < 0.05) and mental health (r = 0.305, P < 0.05), there was no correlation between IS and QOL subdomains (P > 0.05). CONCLUSION Sexual function and satisfaction seem to be correlated with mental and physical health in female and male kidney-transplant recipients, respectively. Although in the two genders, both physical and mental health should be equally evaluated; improving of the sexual function may be better achieved through different approaches.

Abstract
BACKGROUND Chronic pain is prevalent in end-stage renal disease patients undergoing chronic hemodialysis. We do not fully know the intensity of chronic pain experienced by kidney recipients in comparison to those on chronic hemodialysis and healthy controls. Moreover, the effect of chronic pain on kidney recipients' health-related quality of life (HRQoL) is yet to be comprehensively addressed. We designed this study to find an answer to these questions. METHODS In this case control study, we studied 205 kidney recipients, 69 hemodialysis patients, and 100 healthy controls, who were matched for age, sex, monthly family income, and educational level. The patients were evaluated for the intensity of chronic pain by Visual Analogue Scale (VAS). HRQoL was measured with Short Form 36 (SF-36) in the kidney recipients. Chronic pain intensity was compared in the study groups, and in the kidney recipients the correlation between SF-36 subscores and severity of pain was assessed. RESULTS Severity of pain in the kidney recipients was lower than the hemodialysis patients, but more than the healthy controls (P=.001). The VAS pain score negatively correlated with the scores of SF- 36 total (r=-.329, P=01), mental health (r=-.190, P=07), physical health (r=-.275, P=.001), physical function (r=-.339, P=.001), role limitation due to physical problems (r=-.478, P=.001), role limitation due to emotional problems (r=-.326, P=.001), and bodily pain (r=-.894, P=.001). DISCUSSION The intensity of chronic pain experienced by the kidney recipients is less than that experienced by patients under chronic hemodialysis, but higher than healthy subjects. Focusing on chronic pain as a cause of post-renal transplantation morbidity is expected to improve post-renal transplantation quality of life.

Abstract
AIM To observe the effects of fathers' smoking on respiratory symptoms in children between the ages of 6 mo and 5 y living in Tehran during the period January to December 2001. METHODS The caregivers of 622 children attending resident-based clinics in two university hospitals were interviewed about the respiratory illnesses incurred by the child during the previous 12 mo and the smoking habits of those living with the child. Children who lived in households in which any person, other than the father, smoked were excluded. RESULTS The analysis included 595 children, 40.6% of whom were living in homes where fathers smoked cigarettes. About 35% of smokers admitted to unrestricted smoking at home. In children not living with a smoker, 81.6% had experienced at least one episode of upper respiratory tract infection (URTI) during the previous year and the rate increased to 95.2% in passive smokers whose fathers were not restricted from smoking in front of the children, (p-value <0.01). A similar pattern was found for otitis media and asthma (p-value <0.05 and <0.01, respectively). The average number of URTI episodes during the previous year was significantly higher in children exposed to unrestricted smoking (p <0.01). CONCLUSION The study outlines the detrimental effects of paternal smoking on the respiratory health of children from a part of world in which this problem has not been studied previously, and highlights the importance of educating fathers to alter their smoking habits so that even if they do not stop smoking altogether, they should discontinue smoking indoors.

Abstract
Helicobacter pylori infects the majority of the population in the developing countries. However, the rate of gastrointestinal complications such as peptic ulcers and gastric malignancies has no parallel with the infection. In order to determine whether cytotoxin (vacA) and its allelic polymorphism can serve as screening markers for such a population, H. pylori strains were isolated from one hundred and thirty two dyspeptic patients. H. pylori genomic DNA was extracted and underwent PCR-amplification for the cytotoxin alleles. Genotyping of the signal sequence region of the vacA gene identified 68% (70 out of 103) of patients with non ulcer dyspepsia (NUD) and 79% (23 out of 29) of the patients with peptic ulcer disease (PUD) possessing the s1 genotype. S1 strains were significantly more prevalent among patients with PUD as compared to the NUD (p < 0.05). In regard to the middle region, 55% of the patient isolates belonged to the m2 genotype with no correlation to disease. The s1m2 genotype was the most prevalent among all patients and significantly correlated with the PUD group (p < 0.05).

Abstract
The measurement of metabolites constitutes a useful tool for detection of exposure and in pharmacokinetic studies. Epoxidation with subsequent glutathione conjugation and mercapturic acid formation is an important deactivation pathway for naphthalene, a toxin which presumably causes lung disease. The mercapturic acid conjugates of naphthalene [NaphMA (1), N-acetyl-S-(1,2-dihydro-1-hydroxy-2-naphthyl)cysteine (1a), and N-acetyl-S-(1,2-dihydro-2-hydroxy-1-naphthyl)cysteine (1b)], its most important urinary metabolites, and other structurally related derivatives, such as N-acetyl-S-(1,2,3,4-tetrahydro-2-hydroxy-1-naphthyl) cysteine (2), N-acetyl-S-(3-hydroxy-1,2,3,4-tetrahydro-2-naphthyl)cysteine (3), and N-acetyl-S-(2-hydroxy-1-phenylethyl)cysteine (4a) and N-acetyl-S-(2-hydroxy-2-phenylethyl)cysteine (4b) as an isomeric mixture, were synthesized to develop an ELISA (enzyme-linked immunosorbent assay) for the specific detection of NaphMA (1). Compound 1, as an isomeric mixture, was used to raise antibodies by immunizing six rabbits with the corresponding KLH (keyhole limpet hemocyanin) and BSA (bovine serum albumin) derivatives (1KLH and 1BSA). The remaining compounds were covalently attached to BSA, conalbumin, and ovalbumin to be used as coating antigens. The best assay was obtained in a homologous system combining serum Ab2357 (1KLH) and 1BSA as coating antigen. The immunoassay has an I50 of 4-6 ng/mL and a detection limit of 1-2 ng/mL. Because of the known instability of the mercapturic acid conjugate of naphthalene 1, leading to the fully aromatic compound 20, a system involving HPLC is described to check the stability of the NaphMA stock solutions used in the assay. Cross-reactivity studies show high specificity toward the NaphMA. Other related compounds as well as the dehydrated derivative 20 are not recognized by the antibody in this ELISA system.

Abstract
An enzyme-linked immunosorbent assay (ELISA) is reported for the detection and quantitation of 1,3-dinitrobenzene, a widely used chemical intermediate in industrial syntheses and potent testicular toxicant in rats. Radiolabeled [14C]-1,3-dinitrobenzene (25 mg/kg, ip) was administered to rats, and the blood disappearance curve generated with the ELISA assay was compared with HPLC separation and quantitation by using both UV and radiochemical methods. An excellent correlation was found between the two methods. Matrix effects from the blood samples were minimal. Cross reactivity with metabolites of 1,3-dinitrobenzene occurred only at levels that were 3 orders of magnitude greater than for the parent compound. The specificity of the ELISA for 1,3-dinitrobenzene was further demonstrated with a variety of other nitroaromatic compounds, of which only 2,4-dinitrotoluene showed significant cross reactivity. The sensitivity and specificity of the 1,3-dinitrobenzene ELISA demonstrate the usefulness of an approach which, if verified with conventional analytical methods, allows rapid and inexpensive measurement of xenobiotic levels in biological samples.
