  • Serum C-reactive protein(CRP) levels and erythrocyte sedimentation rates(ESR) were measured in 46 patients treated with uncomplicated primary hip replacements, 39 total tip replacements and 7 bipolar hip replacements. In uncomplicated primary hip replacements, ESR levels were slightly elevated preoperatively and were variable postoperatively. But CRP was normal before surgery and elevated in postoperative course, but back to normal within three weeks in most cases. Early success of hip arthroplasty is indicated by normalization of CRP within three weeks, regardless of ESR. Since ESR seems to react somewhat differently from the CRP, both methods are useful in the monitoring of complications after hip arthroplasty.

  • Electron spin resonance (ESR) spectroscopy was used to investigate the effect of irradiation dose on the ESR signal intensity of irradiated crabs and the stability of these radicals under 9 weeks of storage. Swimming and small crabs were irradiated with doses of 0, 1, 3, 5 and 7 kGy using a Co-60 irradiator at ambient temperature. A claw, a walking leg and a cars- pace of the crab pieced and dried were placed in a resonant quart tube within an EPR X-band spectrometer. The irradiated crabs presented an asymmetric absorption in shape at g$_1$=2.002 $\pm$ 0.003 and g$_2$=1.998$\pm$0.005, and were different from the non-irradiated ones. The intensity of the ESR signals was greatest in the claw, intermediate in the carapace and lowest in the walking leg. Samples given low and high doses of irradiation could also be distinguished. The ESR signal after irradiation was stable, even after a 9-week storage.

  • Purpose: Diagnosis of diabetic foot infection is sometimes difficult, since the classical inflammatory signs and leukocytosis may be absent due to the decreased host immune response in diabetics. Therefore inflammatory blood markers, such as white blood cell (WBC) count, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) have been commonly needed to confirm the diagnosis of infection. The purpose of this study is to evaluate the diagnostic usefulness of WBC, ESR and CRP for detection of diabetic foot infection. Methods: Peripheral blood samples were taken from 113 patients with diabetic foot ulcers admitted from June 2007 to April 2009. Diabetic foot infection was diagnosed according to the microbiological culture from soft tissue and bone specimens. Reference values of tests were 4500-11000 /${\mu}L$ for WBC count, 0-20 mm/hr for ESR, and 0-5 mg/L for $CRP^{13,14}$. Sensitivities, specificities, positive and negative predictive values of laboratory tests were calculated and analysed. Receiver-operator characteristic (ROC) curve was also created. Results: There was a significant difference in WBC, ESR, and CRP between infectious group and noninfectious group (p<0.05). The sensitivity of WBC>11,000 /${\mu}L$ ESR > 20 mm/hr, and CRP > 5 mg/L was 30%, 96%, and 84%. The specificity was 86%, 14%, and 50% for WBC, ESR, and CRP, respectively. Positive predictive value was 88%, 78%, and 84%, and negative predictive value was 28%, 50%, and 50% respectively. The areas under the ROC curve for WBC, ESR and CRP were 0.72, 0.75, and 0.78 respectively. Conclusion: Based on the results of this study, we conclude that CRP is more useful method in predicting and diagnosing infection than WBC, ESR in diabetic foot ulcer patients.

  • ZSM-5 gallosilicate molecular sieves was synthesized and cupric ion was ion-exchanged into the gallosilicate. The locations of Cu(ll) species in the framework and their interactions with various adsorbates were characterized by combined electron spin resonance(ESR) and electron spin echo modulation(ESEM) methods. It was found that in a fresh hydrated material, Cu(II) is octahedrally coordinated to six water molecules. This species is located in the channel intersections of two sinusoidal channels and rotates rapidly at room temperature. Evacuation removes some of these water molecules, leaving the Cu(II) coordinated to less water molecules and anchored to of oxygens in the channel wall. Dehydration produces two Cu(II) species, both of which are located in sites inaccessible to oxygen as evidenced by non-broadening of its ESR lines by oxygen. Adsorption of adsorbate molecules such as water, alcohols, ammonia, acetonitrile and ethylene on dehydrated CuNaH-ZSM-5 gallosilicate materials causes changes in the ESR spectrum of Cu(II), indicating the migration of Cu(II) into main channels to form complexes with these adsorbates there. Cu(II) forms a complex with two molecules of methanol, ethanol and propanol, respectively as evidenced by ESR parameters and ESEM data. Cu(II) also forms a square planar complex with four molecules of ammonia, based on the resolved nitrogen superhyperfine interactions and their ESEM parameters. Cu(II) forms a complex with two molecules of acetonitrile based on the ESR parameters and ESEM data. Interestingly, however, only part of Cu(II) interacts indirectly with one molecule of nonpolar ethylene based on ESR and ESEM analyses.

  • Electron spin resonance (ESR) spectroscopy was used to detect radiation-induced signals from irradiated spices and ESR parameters were analyzed to define specific signals. Four powdered spices (red pepper, garlic, onion, and black pepper) were irradiated with 0, 1, 5, or 10 kGy at room temperature using a [60Co] gamma-ray irradiator prior to ESR analysis. Radiation-induced triplet signals, including those from the cellulose radical, which are center signals ($g_2=2.00673$) within the range of 3.0455 mT, were observed in all irradiated spice samples. The parameters g-value, center field, and signal range of hyperfine triplet ESR signals were constant in all irradiated samples, being specific for cellulose radicals and thereby distinguishing these signals from those of nonirradiated control samples. High positive correlation coefficients ($R^2=0.8452-0.9854$) were obtained between irradiation doses and corresponding ESR signal intensities. Thus, reliable detection of irradiated dried spices by measurement of ESR cellulose signals was confirmed by parameter analysis for the cellulose radical.

  • Photostimulated luminescence (PSL), thermoluminescence(TL) and electron spin resonance (ESR) analyses were conducted to detect irradiation treatment of aloe vera powder, which was gamma-irradiated at 1, 3, 5 and 7 kGy. The non-irradiated aloe vera powder indicated below 700 of photon count in PSL, whereas, irradiated at 1 kGy and more, it showed more than 5,000 photon counts, indicating that it is feasible to detect the irradiation of aloe vera powder through PSL In the result of TL, from the minerals of the samples that were irradiated at more than 1 kGy, TL glow curve was able to be seen at around $150^{\circ}C$. As the quantity of irradiation goes up, the ratio of $TL_1\;and\;TL_2$ also increased in proportion to that of irradiation. In the result of ESR analysis, unspecific centeral ESR signal was could be seen. As the amount of irradiation on the samples increased to the level of $R^2=0.97$, the signal intensity also rose similarly. In conclusion, the PSL, TL and ESR exhibited the typical signals induced by irradiation treatment and were able to successfully detect all of the irradiated aloe vera powder. In addition, we found a positive correlation between the intensity of ESR and TL signals and irradiation doses.

  • Background: Acute respiratory distress syndrome (ARDS) is ultimately an inflammatory state. The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) level are inflammatory markers. The aim of this study was to evaluate the value of the ESR, CRP and APACHE II score as prognostic factors for patient with ARDS. Methods: We retrospectively analyzed the medical records of 87 ARDS patients. The predictors (APACHE II score, ESR and CRP) and outcomes (mortality and length of the total hospital stay, the ICU stay and mechanical ventilator care) were obtained from the patients' records. The patients were grouped according to survival as the Survivor and Non survivor groups. We compared the APACHE II score, the ESR and the CRP level between the survivor group and the nonsurvivor group. We evaluated the correlation between the predictors and the outcomes. The initial ESR, CRP level and APACHE II score were checked at the time of ICU admission and the second ESR and CRP level were checked $3.3{\pm}1.2$ days after ICU admission. Results: Thirty-eight (43.7%) patients remained alive and 49 (56.3%) patients died. The APACHE II score was significantly lower for the survivor group than that for the non survivor group ($14.7{\pm}7.6$ vs $19.6{\pm}9.1$, respectively, p=0.006). The initial ESR and CRP level were not different between the survivor and non-survivor groups (ESR $64.0{\pm}37.8mm/hr$ vs $63.3{\pm}36.7mm/hr$, respectively, p=0.93, CRP $15.5{\pm}9.6mg/dl$ vs $16.3{\pm}8.5mg/dl$, respectively, p=0.68). The decrement of the CRP level for the survivor group was greater than that for the non survivor group ($-8.23{\pm}10.0mg/dl$ vs $-1.46{\pm}10.1mg/dl$, respectively, p=0.003). Correlation analysis revealed the initial ESR was positively correlated with the length of the total hospital stay and the ICU stay (correlation coefficient of the total hospital days: R=0.43, p=0.001, correlation coefficient of the ICU stay: R=0.39, p=0.014). Conclusion: The initial APACHE II score can predict the mortality of ARDS patients, and the degree of the early CRP change can be a predictor of mortality for ARDS patients. The initial ESR has positive correlation with the ARDS patients' duration of the total hospital stay and the ICU stay.

  • Bone mineral density (BMD) is used in the clinical diagnosis of osteoporosis and the assessment of fracture risk. Osteoporosis, characterized mainly by decreased BMD, is a highly heritable complex disorder and a major public health concern to hundreds of millions of elderly persons worldwide. However, the specific genetic variants determining risk for low bone density are still largely unknown. Here, we performed association analysis to elucidate the possible relations of genetic polymorphisms in ESR1 gene with low bone density. By examining genotype data of a total of 1813 women in the Korean Association REsource (KARE) study, we discovered the ESR1 gene polymorphisms are associated with decreased BMD and osteoporosis. The results on the BD-RT (bone density estimated by T-score at distal radius), three SNPs (rs2248586, rs9371557, and rs1569788) within the ESR1 gene were significantly associated with bone density. The results on the BD-TT (bone density estimated by T-score at midshaft tibia), five SNPs (rs9371552, rs2248586, rs712221, rs7772475, and rs3798577) were significantly associated with bone density. The SNP rs2248586 within the ESR1 gene had commonly significance in both BD-RT (${\beta}$=-0.151, dominant P=0.049) and BD-TT (${\beta}$=-0.156, dominant P=0.039). In the SNP rs2248586, their ${\beta}$-values in BD-RT and/or BD-TT showed consistent trends with the odds ratios (ORs) of osteoporosis. In summary, we found statistically significant SNPs in ESR1 gene that are associated with both decreased BMD and osteoporosis traits. Therefore, our findings suggest ESR1 gene could be related to pathogenesis of osteoporosis.

  • We investigated the effect of ESR gene-based selection on an improvement of litter size in the herds in real (non-experimental) conditions. The pigs were selected for three years. In the tested population the pigs were mated according to a breeding scheme where the individuals with at least one ESR-B allele were preferred in the selection. In the control group (CP; n = 140) the pigs were mated just according to a breeding scheme without knowledge of the ESR genotype. We observed a significant increase in litter size (total number of born, number of born alive and number of weaned piglets per litter) in the final tested ESR-selected population (LP; n = 184) and an insignificant increase in CP as compared with the original population (OP; n = 155). After the selection we could observe a significant increase in the frequency of allele B in LP. Frequency of the genotypes AB and BB increased in both LP and CP; the distribution of the genotypes changed significantly only in LP. An association analysis of the ESR gene effects on reproductive traits in LP showed no significant differences between the genotypes. The results of our study suggest that ESR gene-based selection can be successful also in small herds, under real (non-experimental) conditions with a respect for general breeding principles and limitations and during a short period. An examination of a larger sample population as well as an analysis of selection consequences on other traits (meat and carcass quality) could bring a more conclusive evaluation of ESR-based selection. Nevertheless, the results are encouraging especially for small breeding farms taking a perspective of better litter size improvement.

  • Purpose: This study considers the variables related to self-leadership of Korean nursing students and verifies the results of precedent studies through meta-analysis. Methods: This study selected a total of 48 precedent studies regarding the investigation of the correlation between variables related to self-leadership of nursing students conducted between 2009 and 2019 and carried out a meta-analysis. Results: For the effect size of variables related to self-leadership of nursing students, individual characteristics had a medium effect size (ESr=.49) and the effect size was larger for meta-cognition (ESr=.65), emotional intelligence (ESr=.58), and self-efficacy (ESr=.54). The characteristics of nursing competency (ESr=.45) also had a medium effect size and the effect size was larger for professional self-concept (ESr=.60), social support (ESr=.58), and critical thinking (ESr=.56). This result shows that individual characteristics were highly correlated with self-leadership compared to the characteristics of nursing competency. Conclusion: This study is significant in that it verified the effect of variables related to self-leadership and presented the direction and preliminary data for a follow-up study. It is necessary to include variables considering individual characteristics in the development of an educational program for improving self-leadership in the future.
