Abstract
OBJECTIVE This study is to assess the diagnostic performance of magnetic resonance imaging (MRI) findings for type 1B triangular fibrocartilage complex (TFCC) tear of the wrist. MATERIALS AND METHODS This study retrospectively enrolled 78 patients to examine the diagnostic performance of preoperative MRI examinations in patients with type 1B TFCC tears. Thirty-nine participants had confirmed type 1B TFCC tear. The control group included 39 patients who were randomly selected from 1157 patients who underwent MRI for wrist pain. Both groups underwent a review of 19 MRI findings by two independent radiologists, and the correlation between each diagnostic finding and type 1B TFCC tear was assessed using the chi-squared test. The 19 MRI findings comprised eight primary signs of abnormalities in the distal or proximal lamina, in conjunction with 11 secondary signs suggestive of abnormalities in the surrounding structures. RESULTS The TFCC tear group demonstrated a significantly higher incidence of two primary MRI signs, i.e., fiber discontinuity and signal alteration in the distal lamina, as observed by both readers (R1, 74.4% vs. 38.5%, p = 0.003, and 87.2% vs. 43.6%, p < 0.001; R2, 74.4% vs. 35.9%, p = 0.001, and 87.2% vs. 53.8%, p < 0.003, respectively). Reader 2 identified a higher prevalence of two additional primary MRI signs: fiber discontinuity and signal alteration in the proximal lamina (all p < 0.05). None of the 11 secondary MRI signs demonstrated statistically significant associations with type 1B TFCC. CONCLUSION MRI manifestations of fiber discontinuity and signal alteration in the distal lamina may provide predictive markers for type 1B TFCC wrist tear.

Abstract
Translationally controlled tumor protein (TCTP), a highly conserved protein present in most eukaryotes, is involved in numerous biological processes. Only the dimeric form of TCTP (dTCTP) formed during inflammatory conditions exhibits cytokine-like activity. Therefore, dTCTP is considered as a therapeutic target for allergic diseases. Because monomeric TCTP (mTCTP) and dTCTP share a high topological similarity, we hypothesized that small molecules interacting with mTCTP would also bind to dTCTP and interfere with dTCTP-based cellular processes. In this study, nine compounds listed in the literature as interacting with mTCTP were investigated for their ability to suppress the activity of extracellular dTCTP in bronchial epithelial cells. It was found that one of the nine, meclizine, a piperazine-derivative antihistamine, significantly reduced IL-8 release and suppressed the NF-κB pathway. The direct interaction of meclizine with dTCTP was confirmed by surface plasmon resonance (SPR). Also, we found that meclizine can attenuate ovalbumin (OVA)-induced airway inflammation in mice. Therefore, meclizine might be a potential anti-allergic drug as an inhibitor for dTCTP.

Abstract
Psoriasis is a chronic skin inflammation caused by a dysfunctional immune system, which causes systemic inflammation in various organs and tissues. Due to the risk of systemic inflammation and recurrence of psoriasis, it is important to identify the critical targets in the pathogenesis of psoriasis and develop targeted therapeutics. Dimerized translationally controlled tumor protein (dTCTP) promotes immune cell activation as a pro-inflammatory cytokine and plays a role in developing allergic diseases such as asthma and rhinitis. Here, we sought to explore whether dTCTP and its inhibition contributed to the development and control of imiquimod (IMQ)-induced psoriasis. Topical application of IMQ inflamed the skin of the back and ear, increased inflammatory cytokines, and decreased regulatory T cell markers. Interestingly, TCTP was significantly increased in inflamed skin and immune cells such as T cells, B cells, and macrophages after IMQ treatment and was secreted into the serum to undergo dimerization. Extracellular dTCTP treatment selectively suppressed regulatory T (Treg) cells, not other effector T helper (Th) cells, and increased M1 macrophages. Moreover, dTCTP-binding peptide 2 (dTBP2), a dTCTP inhibitor peptide, effectively attenuated the systemic inflammatory responses, including Th17 cell response, and alleviated psoriatic skin inflammation. dTBP2 blocked dTCTP-mediated Treg suppression and stimulated the expression of Treg cell markers in the spleen and inflammatory skin lesions. These results suggest that dTCTP dysregulated immune balance through Treg suppression in psoriatic inflammation and that functional inhibition of dTCTP by dTBP2 maintained immune homeostasis and attenuated inflammatory skin diseases by expanding Treg cells.

Abstract
BACKGROUND SyntheChol is a new synthetic, non-animal-derived cholesterol that is easily dissolved in ethanol, ready to use, and behaves in a similar way as natural cholesterol. Therefore, it could be used as a substitute of natural cholesterol in dog sperm freezing extender. OBJECTIVE To evaluate the effect of supplementing an egg yolk-free (EY-free) extender with synthetic cholesterol (SyntheChol) on cryopreserved dog sperm. MATERIALS AND METHODS Spermatozoa (1 × 108 sperm/mL) were suspended in EY-free extender supplemented with 0 % (control), 0.25, 0.5, 1, 2, 4, or 6 % SyntheChol (Extender 1), cooled at 4 degree C for 1 h, and diluted (1:1, v/v) with Extender 1 containing 1 M glycerol. The spermatozoa were then cooled to 4 degree C for 30 min. Sperm-containing straws were frozen using LN2 vapor. Sperm motility (computer-assisted sperm analysis, CASA), sperm membrane integrity (SYBR-14 and PI staining), and acrosome integrity (FITC-PSA) were evaluated after thawing. Thereafter, optimal concentrations were determined (0.25, 0.5, 1, or 2 %) and used to evaluate reactive oxygen species (ROS) generation, apoptosis, and the gene expression of motility-related sperm mitochondria-associated cysteine-rich protein, apoptosis-related B-cell lymphoma 2 (BCL2), and BCL2-associated X protein (BAX) in cryopreserved sperm. RESULTS Sperm progressive motility, membrane integrity, and acrosome integrity were markedly greater in the SyntheChol-supplemented groups (0.25, 0.5, 1, or 2 %) than in the control group. Only BAX expression was significantly reduced in the SyntheChol groups (0.25, 1, or 2 %) compared with the control group. However, there were no significant effects on the ROS generation or apoptosis index. CONCLUSION SyntheChol (0.25, 1, or 2 %) proved to be effective in reducing the BAX gene expression level and improving sperm progressive motility, and membrane and acrosome integrity. doi.org/10.54680/fr22210110212.

Abstract
Accurate image interpretation of Waters’ and Caldwell view radiographs used for sinusitis screening is challenging. Therefore, we developed a deep learning algorithm for diagnosing frontal, ethmoid, and maxillary sinusitis on both Waters’ and Caldwell views. The datasets were selected for the training and validation set (n = 1403, sinusitis% = 34.3%) and the test set (n = 132, sinusitis% = 29.5%) by temporal separation. The algorithm can simultaneously detect and classify each paranasal sinus using both Waters’ and Caldwell views without manual cropping. Single- and multi-view models were compared. Our proposed algorithm satisfactorily diagnosed frontal, ethmoid, and maxillary sinusitis on both Waters’ and Caldwell views (area under the curve (AUC), 0.71 (95% confidence interval, 0.62–0.80), 0.78 (0.72–0.85), and 0.88 (0.84–0.92), respectively). The one-sided DeLong’s test was used to compare the AUCs, and the Obuchowski–Rockette model was used to pool the AUCs of the radiologists. The algorithm yielded a higher AUC than radiologists for ethmoid and maxillary sinusitis (p = 0.012 and 0.013, respectively). The multi-view model also exhibited a higher AUC than the single Waters’ view model for maxillary sinusitis (p = 0.038). Therefore, our algorithm showed diagnostic performances comparable to radiologists and enhanced the value of radiography as a first-line imaging modality in assessing multiple sinusitis.

Abstract
BACKGROUND Amino acids (AAs) have been indicated to have cryoprotective and antioxidative effects on sperm freezing using egg yolk (EY)-based extender. However, EY-based extender is difficult to be standardized for the effect of amino acids because the EY composition varies with the animal's diet. OBJECTIVE To test the effect of AAs in EY-free polyvinyl alcohol (EY-free PVA) extender and develop a chemically defined extender for dog sperm cryopreservation. MATERIALS AND METHODS In the first experiment (E1), dog spermatozoa (1x108 sperms/mL) were frozen with EY-free PVA extender without AAs or supplemented with essential (EAAs, 50 x: 1, 2, 4 %) or non-essential amino acids (NEAAs, 100 x: 1, 2, 4 %). In the second experiment (E2), spermatozoa were frozen with EY-free PVA extender supplemented with 0, 0.5, 1 or 2 % of an EAA-NEAA mixture. Motility, viability and acrosome integrity were evaluated after thawing in E1 and E2. In the third experiment (E3), spermatozoa were frozen using an extender supplemented with 2 % EAAs, 2 % NEAAs or a 0.5 % EAA-NEAA mixture. Reactive oxygen species (ROS) and phosphatidylserine (PS) translocation were assessed. Expression of genes for motility-related sperm mitochondrial-associated cysteine-rich protein (SMCP), apoptosis-related B-cell lymphoma 2 (BCL2) and BCL2 associated X protein (BAX) was measured. RESULTS Addition of EAAs, NEAAs or an EAA-NEAA mixture to EY-free PVA extender significantly increased sperm motility without affecting viability. Only 1 % NEAAs significantly increased the acrosome membrane. EAA-NEAA mixture (0.5 %) significantly increased SMCP, BCL2 and BAX expression compared to the control group without significant effect on PS translocation or ROS. CONCLUSION EAAs and NEAAs addition in EY-free PVA extender improved sperm motility, with limited effect on acrosome integrity and gene expression of SMCP, BCL2 and BAX during dog sperm cryopreservation.

Abstract
BACKGROUND The optimal first-line mechanical thrombectomy (MT) method in cancer-related stroke (CRS) patients with emergent large vessel occlusion (ELVO) remains largely unknown. The aim of this study is to evaluate the efficacy and safety between contact aspiration (CA) first-line thrombectomy and stent retriever (SR) first-line thrombectomy in CRS patients. METHODS Sixty-two CRS patients with ELVO, who underwent MT between January 2013 and October 2019 at our institution, were retrospectively analyzed. Patients were divided into two groups based on the first-line MT method and compared: the CA group (n=28), which included those who received CA alone or combined CA with SR, and the SR group (n=34), which included those who received conventional SR alone. RESULTS Overall, reperfusion was successful in 75.8% (47/62) of CRS patients, and a good clinical outcome at 90 days was observed in 17.7%. The CA group showed a higher rate of successful reperfusion (89.3% vs 64.7%, P=0.025) shorter procedure time (22 vs 42 min; P=0.029), higher rate of first pass effect (35.7% vs 11.8%, P=0.025), and lower number of passes (1 vs 3, P=0.023) when compared with the SR group. The procedural and hemorrhagic complication rates were similar between the CA and SR groups. The first-line contact aspiration (OR 11.624, 95% CI 1.041 to 129.752; P=0.046) was an independent predictor of successful reperfusion. CONCLUSIONS Among patients with CRS, CA - whether alone or in combination with SR - as first-line MT seems to provide more rapid and successful reperfusion when compared with SR.

Abstract
Abstract
The constant exposure to fine particulate matter (PM) induces oxidative stress and proinflammatory cytokine production. The ROS formed by oxidative stress is related to activate NF-κB signal pathway for inflammation. Sargassum horneri, a brown algae found in East Asia, is known to be an excellent source for bioactive components. In this study, the antioxidant and anti-inflammation effects of Sargassum horneri ethanol extract (SHE) on the PM-induced oxidative stress in MLE-12, a type II alveolar epithelial cell line were investigated. As the exposure concentration of PM increased to 1,000 μg/mL, the cell viability was reduced; however, it was increased when treated with SHE. The ROS generation and lipid peroxidation of MLE-12 cells were increased from the PM concentration of 125 μg/mL and they were reduced after treatment of SHE at 62.5 and 125 μg/mL. The expressions of antioxidant enzymes, catalase (CAT) and superoxide dismutase (SOD2), in MLE-12 cells exposed to PM were lower than those exposed to PM with SHE. The PM was proved to increase the expression of 8-OHdG, one of DNA oxidative damage markers, and OGG1, the repair enzyme of 8-OHdG, while SHE protected the DNA damage of cell. The expression of NF-κB signaling was reduced by SHE. These results suggest that SHE can adjust the expression of antioxidant enzymes, help to suppress the oxidative stress induced by PM, and attenuate its oxidative damage and NF-κB pathway to lung epithelial cells by eliminating over-produced ROS.

Abstract
The cross-section of the mainstem bronchi is not completely round. For preoperative selection of a double-lumen endobronchial tube size, it may be necessary to measure the mediolateral and the anteroposterior bronchial diameters, which can be measured respectively on chest radiograph and computed tomography. With Internal Review Board approval and patients’ informed consent, 105 elective thoracic surgical patients who needed left-sided double-lumen tubes were enrolled. Double-lumen tube size was selected depending on the arithmetic mean of the mediolateral and anteroposterior bronchial diameters. Moreover, the outer diameters of the bronchial tube should be smaller than both mediolateral and anteroposterior diameters. The recommended bronchial diameter for each double-lumen tube size was chosen so that the mean of the two bronchial diameters was 0 to 2.0 mm larger than the upper limit of 95% confidence interval of the averaged outer diameter of the bronchial tube of the selected double-lumen tube. In no case was the predicted double-lumen tube size inappropriate. Generally, anteroposterior bronchial diameters appeared to be different from mediolateral diameters (P=0.001). The double-lumen tube size to be selected based on only one bronchial diameter was different from the one selected based on two perpendicularly measured bronchial diameters in 54.3% of patients (57/105). Preoperative selection of the double-lumen tube size based on the anteroposterior, mediolateral and mean bronchial diameters seems to be useful in that this may obviate the need to change an inappropriately sized double-lumen tube and may be helpful in reducing the related complications.

Abstract
BACKGROUND Combined liver and kidney transplant is a very complex surgery. To date, there has been no report on the intraoperative management of patients with impaired cardiac function undergoing simultaneous ABO-compatible liver and ABO-incompatible kidney transplant from 2 living donors. CASE REPORT A 60-year-old man underwent simultaneous ABO-compatible liver and ABO-incompatible kidney transplant from 2 living donors because of IgA nephropathy and alcoholic liver cirrhosis. The preoperative cardiac findings revealed continuous aggravation, shown by large left atrial enlargement, severe left ventricular hypertrophy, a very prolonged QT interval, and a calcified left anterior descending coronary artery. Severe hypotension with very weak pulsation and severe bradycardia developed, with an irregular junctional rhythm noted immediately after the liver graft was reperfused. Although epinephrine was administered as a rescue drug, hemodynamics did not improve, and central venous pressure and mean pulmonary arterial pressure increased to potentially fatal levels. Emergency phlebotomy via the central line was performed. Thereafter, hypotension and bradycardia recovered gradually as the central venous pressure and mean pulmonary arterial pressure decreased. The irregular junctional rhythm returned to a sinus rhythm, but the QTc interval was slightly more prolonged. Because of poor cardiac capacity, the volume and rate of fluid infusion were increased aggressively to maintain appropriate kidney graft perfusion after confirming vigorous urine production of the graft. CONCLUSIONS A heart with impaired function due to both end-stage liver and kidney diseases may be less able to withstand surgical stress. Further study on cardiac dysfunction will be helpful for the management of patients undergoing complex transplant surgery.

Abstract
We studied the predictive performance of the Minto pharmacokinetic model during cardiopulmonary bypass in patients undergoing cardiac surgery. Patients received remifentanil target-controlled infusion using the Minto model during total intravenous anaesthesia with propofol. From 56 patients, 275 arterial blood samples were drawn before, during and after bypass to determine the plasma concentration of remifentanil, and the predicted concentrations were recorded at each time. For pooled data, the median prediction error and median absolute prediction error were 21.3% and 21.8%, respectively, and 22.1% and 22.3% during bypass. Both were 148.4% during hypothermic circulatory arrest and measured concentrations were more than three times greater than predicted (26.9 (17.0) vs. 7.1 (1.6) ng.ml-1 ). The Minto model showed considerable bias but overall acceptable precision during bypass. The target concentration of remifentanil should be reduced when using the Minto model during hypothermic circulatory arrest.

Abstract
The agricultural transition profoundly changed human societies. We sequenced and analysed the first genome (1.39x) of an early Neolithic woman from Ganj Dareh, in the Zagros Mountains of Iran, a site with early evidence for an economy based on goat herding, ca. 10,000 BP. We show that Western Iran was inhabited by a population genetically most similar to hunter-gatherers from the Caucasus, but distinct from the Neolithic Anatolian people who later brought food production into Europe. The inhabitants of Ganj Dareh made little direct genetic contribution to modern European populations, suggesting those of the Central Zagros were somewhat isolated from other populations of the Fertile Crescent. Runs of homozygosity are of a similar length to those from Neolithic farmers, and shorter than those of Caucasus and Western Hunter-Gatherers, suggesting that the inhabitants of Ganj Dareh did not undergo the large population bottleneck suffered by their northern neighbours. While some degree of cultural diffusion between Anatolia, Western Iran and other neighbouring regions is possible, the genetic dissimilarity between early Anatolian farmers and the inhabitants of Ganj Dareh supports a model in which Neolithic societies in these areas were distinct.

Abstract
AIM This study aimed to assess the intent to enrol in a master of nursing programme among Bangladesh nurses, identify preferred programme options and measure the association among intent to enrol in the programme, clinical competency and job satisfaction. BACKGROUND Personal and professional aspects of potential students pursuing graduate education are beneficial in devising educational strategies. However, considering the pressing needs for higher nursing education, there are no masters of nursing programmes in Bangladesh. METHODS This study used a descriptive correlational design. Nurses working in Bangladesh public sector were recruited to participate in a self-administered survey (n = 260). The questionnaire consisted of perception of job satisfaction, clinical competency and the need for educational options, including the intent to enrol in a master of nursing programme, preferred specialty area, curriculum content and career goals after graduation. Data were analysed using descriptive statistics and point-biserial correlation. RESULTS Ninety per cent of the respondents reported that they intended to enrol in a master of nursing programme. Intention was significantly correlated with clinical competency but not with job satisfaction. The most preferred specialty areas were nursing management and education. Half of the respondents responded that teaching at nursing schools was a career goal after graduation. DISCUSSION The results of the needs assessment for the programme reflected the unique interest and priorities of the current status of Bangladesh. CONCLUSIONS The results indicate a strong motivation to enrol in a master of nursing programme, confidence in clinical competence and high demand for programme in nursing management and education. These findings should be considered to design the programme in order to meet the interest of Bangladesh nurses. IMPLICATIONS FOR NURSING AND HEALTH POLICY Educational needs assessments should take precedence to ensure the best possible educational outcome and to produce competent nurses who will contribute in achieving the Millennium Development Goals of Bangladesh.

Abstract
We retrospectively investigated whether palonosetron administered during the induction of general anesthesia is associated with an increased risk of perioperative cardiovascular complications in a single tertiary center cohort consisting of 4,517 palonosetron-exposed patients and 4,517 propensity score-matched patients without palonosetron exposure. The primary endpoint was a composite of perioperative cardiovascular complications, including intraoperative cardiac arrhythmia, intraoperative cardiac death, and myocardial injury within the first postoperative week, and there was no significant difference between the groups (odds ratio [OR] = 1.04; 95% confidence interval [CI] = 0.92-1.19). As secondary endpoints, intraoperative cardioversion, cardiac compression, use of cardiovascular drugs, postoperative hospital stay, and in-hospital mortality showed no differences between the groups. However, the palonosetron group showed decreased intraoperative hypotension (OR = 0.88; 95% CI = 0.79-0.97) and length of postoperative intensive care unit (ICU) stay (4.26 ± 9.86 vs. 6.14 ± 16.75; P = 0.026). Palonosetron did not increase the rate of perioperative cardiovascular complications, and can therefore be used safely during anesthetic induction.

Abstract
Autophagy is a critical process for the maintenance of cellular homeostasis and mammalian early embryogenesis. Autophagy can be regulated by various chemical inducers. However, there are few reports about effect of autophagy inducer in vitro maturation (IVM) of porcine oocyte. The present study investigated the effects of supplementary trehalose, a novel mTOR-independent autophagy enhancer, on oocyte maturation and embryonic development after parthenogenetic activation (PA). Immature oocytes were treated with various concentrations (0, 25, 50, and 100 mM) of trehalose in M-199 (Invitrogen, Carlsbad, CA) supplemented with 10 ng mL–1 of epidermal growth factor (EGF; Sigma-Aldrich Corp.), 1 ug mL–1 of insulin (Sigma-Aldrich Corp.), 4 IU mL–1 of pregnant mare serum gonadotropin (PMSG; Intervet, Boxmeer, Holland), 4 IU mL–1 of human chorionic gonadotropin (hCG; Intervet), and 10% (vol/vol) porcine follicular fluid (pFF) for 10 h, and transferred to another IVM medium without trehalose. Osmolality of each groups (0, 25, 50, and 100 mM trehalose) was in the 290 to 295, 310 to 315, 330 to 335, and 375 to 380 osmol range, respectively. After 44 h of IVM, trehalose treatment during IVM did not improve nuclear maturation rates of oocytes in any group (90.7, 92.1, 92.7, and 90.1%, respectively). The developmental competence of oocytes matured with different trehalose concentrations was evaluated after PA. There were no significant differences in cleavage rates. However, blastocyst (BL) formation was different. Oocytes treated with 25 mM of trehalose during IVM had a significantly higher (P < 0.05) BL formation rate (64.2%) after PA compared with the control (52.0%). The BL quality was also improved in the 25 mM trehalose-treated group. Early BL rate significantly reduced in the 25 mM trehalose-treated group as compared to control (19.6 v. 29.9%, P < 0.05). By contrast, expanded BL rate significantly increased in the 25 mM trehalose-treated group than of control (27.7 v. 11.0%, P < 0.05). Total cell numbers of BL were significantly higher (P < 0.05) in the 25 mM trehalose-treated group compared to those in the control group (52.2 v. 36.8). However, BL rate and quality of oocytes treated with 50 and 100 mM trehalose were similar with control group. In conclusion, these results indicate that 25 mM trehalose during IVM improved the developmental potential of porcine embryos. Trehalose will be useful for large-scale production of BL with good quality in porcine in vitro production.This work was supported by a grant from the Next-Generation Bio Green 21 Program (No. PJ009563032014), Rural Development Administration, Republic of Korea.

Abstract
The incidence of metabolic syndrome is increasing globally, as the prevalence of obesity continues to rise. However, the basic mechanisms of metabolic syndrome are not completely known yet. Therefore, animal disease models are required for the study of metabolic syndrome. The overexpression of 11 β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) in mice leads to metabolic syndrome; thus, we attempted to produce pigs with overexpression of 11β-HSD1 gene by somatic cell nuclear transfer (SCNT). However, low transgenic (TG) efficiency has been an obstacle to the production of TG pigs. A SCNT method in which somatic cells derived from TG pig are used as the nuclear donor (re-cloning method) is an effective technique for TG pig production. In this study, we attempted to increase TG efficiency by the re-cloning method. Pregnancy efficiency, production efficiency, and TG efficiency were compared with sources of donor cells (transfected TG fetal fibroblast v. TG fibroblast derived from newborn TG cloned pig). A total of 1382 and 881 TG SCNT embryos were produced from fetal fibroblast v. cloned fibroblast, and then transferred to 13 and 10 recipients. The pregnancy rate was not significantly different (30.8% v. 20.0%). Seventeen live piglets and 5 stillborn piglets were born from 4 recipients in the fetal fibroblast group, and 8 live piglets, 2 stillborn piglets, and 3 mummies were born from 2 recipients in the cloned fibroblast group. There were no significant differences in the production efficiency (3.7% v. 5.0%). All of the 13 re-cloned piglets showed reporter and target gene integration. But, of 22 fetal fibroblast-cloned piglets, reporter gene integration was confirmed in 9, but only 3 clone piglets showed reporter gene integration. Efficiency of TG was significantly increased in re-cloning group (13.6% v. 100.0%). In this study, TG efficiency of 11β-HSD1 overexpressed pigs was improved by re-cloning method. These results indicate that re-cloning is an efficient method for production of TG cloned pigs.This work was supported by a grant from the Next-Generation Bio Green 21 Program (No. PJ009563032014), Rural Development Administration, Republic of Korea.

Abstract
BACKGROUND A number of 'proof-of-concept' trials suggest that remote ischaemic preconditioning (RIPC) reduces surrogate markers of end-organ injury in patients undergoing major cardiovascular surgery. To date, few studies have involved hard clinical outcomes as primary end-points. METHODS Randomised clinical trials of RIPC in major adult cardiovascular surgery were identified by a systematic review of electronic abstract databases, conference proceedings and article reference lists. Clinical end-points were extracted from trial reports. In addition, trial principal investigators provided unpublished clinical outcome data. RESULTS In total, 23 trials of RIPC in 2200 patients undergoing major adult cardiovascular surgery were identified. RIPC did not have a significant effect on clinical end-points (death, peri-operative myocardial infarction (MI), renal failure, stroke, mesenteric ischaemia, hospital or critical care length of stay). CONCLUSION Pooled data from pilot trials cannot confirm that RIPC has any significant effect on clinically relevant end-points. Heterogeneity in study inclusion and exclusion criteria and in the type of preconditioning stimulus limits the potential for extrapolation at present. An effort must be made to clarify the optimal preconditioning stimulus. Following this, large-scale trials in a range of patient populations are required to ascertain the role of this simple, cost-effective intervention in routine practice.

Abstract
BACKGROUND Inflammation plays a key role in the pathogenesis of vascular occlusive diseases, such as myocardial infarction and stroke. Additionally, these conditions are predicted by C-reactive protein (CRP), a general inflammation marker. We hypothesized that the inflammation induced by surgery itself augments vascular occlusive disease. We retrospectively evaluated the relationship between postoperative CRP elevation and postoperative major adverse cardiovascular and cerebral events (MACCE) in patients undergoing off-pump coronary artery bypass surgery (OPCAB). METHODS The electronic medical records of 1046 patients who underwent OPCAB were reviewed retrospectively. The relationship between postoperative serum CRP and long-term postoperative MACCE (median follow-up 28 months) was investigated. RESULTS Patients were divided into quartiles according to maximum postoperative CRP levels (<18, 18-22, 22-27, ≥27 mg dl(-1)). The adjusted hazard ratios (HRs) were 2.15, 2.45, and 2.81, respectively (P=0.004), compared with the lowest quartile (<18 mg dl(-1)). In the multivariate analysis, the postoperative CRP quartile (HR 2.81; P=0.004), postoperative non-use of statins (HR 1.86; P=0.003), and postoperative maximum troponin I (HR 1.02; P<0.001) independently predicted postoperative MACCE, while preoperative CRP did not (P=0.203). Several parameters were correlated with postoperative maximum CRP level: body temperature (P=0.001) and heart rate (P<0.001) at the end of surgery; intraoperative last lactate (P<0.001) and base excess (P<0.001); and red blood cell transfusion (P=0.019). CONCLUSIONS Postoperative CRP elevation was associated with long-term postoperative MACCE in OPCAB patients. This was mitigated by postoperative statin medication. Furthermore, postoperative CRP elevation was associated with intraoperative parameters reflecting hypoperfusion and inflammation.

Abstract
We evaluated whether pulse pressure variation can predict fluid responsiveness in spontaneously breathing patients. Fifty-nine elective thoracic surgical patients were studied before induction of general anaesthesia. After volume expansion with hydroxyethyl starch 6 ml.kg(-1) , patients were defined as responders by a ≥ 15% increase in the cardiac index. Haemodynamic variables were measured before and after volume expansion and pulse pressure variations were calculated during tidal breathing and during forced inspiratory breathing. Median (IQR [range]) pulse pressure variation during forced inspiratory breathing was significantly higher in responders (n = 29) than in non-responders (n = 30) before volume expansion (18.2 (IQR 14.7-18.2 [9.3-31.3])% vs. 10.1 (IQR 8.3-12.6 [4.8-21.1])%, respectively, p < 0.001). The receiver-operating characteristic curve revealed that pulse pressure variation during forced inspiratory breathing could predict fluid responsiveness (area under the curve 0.910, p < 0.0001). Pulse pressure variation measured during forced inspiratory breathing can be used to guide fluid management in spontaneously breathing patients.

Abstract
Zinc (Zn) is one of the abundant transition metals in biology and is an essential component of most cells. However, there are few reports about the effect of Zn in porcine oocytes. The objective was to investigate the effects of supplementary Zn during in vitro maturation (IVM) of porcine oocytes. We investigated nuclear maturation, intracellular glutathione (GSH) levels, reactive oxygen species (ROS) levels, and subsequent embryonic development after IVF. Before the experiment, Zn concentrations in IVM medium and body fluids were measured using inductively coupled plasma spectrophotometer (sensitivity: 1 μM) and treatment concentrations were determined. Zinc concentration was 12.6 μM in porcine plasma and 12.9 μM in porcine follicular fluid. We confirmed that Zn was not detected in IVM medium. A total of 541 cumulus–oocyte complexes (COC) were used for the evaluation of nuclear maturation. The COC were matured in TCM-199 medium supplemented with various concentrations of Zn (0, 6, 12, 18, and 24 μM). After 44 h of IVM, no significant difference was observed in all groups (metaphase II rate: 85.7, 88.7, 90.4, 90.3, and 87.2%, respectively). A total of 100 matured oocytes were examined for the effects of different Zn concentrations (0, 6, 12, 18, and 24 μM) on porcine oocyte intracellular GSH and ROS levels, which were measured through fluorescent staining and image analysis program. The groups of 12, 18, and 24 μM showed a significant (P < 0.05) increase in intracellular GSH levels (1.45, 1.67, and 1.78, respectively) compared with the control and 6 μM group (1.00 and 1.08, respectively). The intracellular ROS level of oocytes matured with 12, 18, and 24 μM (0.82, 0.68, and 0.55) were significantly (P < 0.05) decreased compared with the control and 6 μM groups (1.00 and 1.03, respectively). Finally, the developmental competence of oocytes matured with different concentrations of Zn (0, 6, 12, 18, and 24 μM) was evaluated after IVF. There were no significantly different in cleavage rates. However, cleavage patterns and blastocyst (BL) formation were different. Fragmented embryo ratio of the 12 μM group (14.9%) was significantly lower than that of the other groups (control, 6, 18, and 24 μM: 26.4, 17.8, 18.4, and 18.0%, respectively). Oocytes treated with 12 μM Zn during IVM had a significantly higher BL formation rate (28.2%) after IVF compared with the control (19.8%). In conclusion, these results indicate that Zn treatment as body fluid concentration during IVM improved the developmental potential of IVF in porcine embryos by increasing the intracellular GSH concentration and decreasing the ROS level.

Abstract
Evaluation of morphology of first polar body (1st PB) could be a method for the oocyte's quality and developmental competence. The developmental potential of oocyte with fragmented PB after in vitro maturation (IVM) is a controversial issue. The aim of this study is to investigate the effects of PB morphology type on oocyte quality and developmental competence after IVF. Porcine ovaries were obtained from prepubertal gilts at a local slaughterhouse and transported to the laboratory within 2 h in physiological saline supplemented with 100 IU mL–1 penicillin G and 100 mg mL–1 streptomycin sulfate. The cumulus–oocyte complexes (COC) were aspirated using an 18-gauge needle attached to a 10-mL disposable syringe from superficial follicles 3 to 6 mm in diameter followed by IVM. After IVM, oocytes were classified into 3 types as follows, oocytes with normal PB (A type), oocytes with a little of fragmented PB (B type), and oocytes with separated 2 PBs (C type), respectively. As classification of PB types, we analysed the distribution ratio of each PB type after IVM, and then performed IVF for analysis of fertilization rate and developmental potential. The ratio of oocyte with A type (73%) was significantly (P < 0.05) higher than that of B type (24.5%) or C type (2.5%) after IVM. Only mature oocytes were selected from A and B type and were subjected to IVF because of a small number of oocytes with C type. In the IVF experiment, the efficiency of monospermy and fertilization were significantly higher in oocytes of A type (46.7%) than those of type B (20.0%). The cleavage rate of oocytes with A type (63.9%) was significantly (P < 0.05) higher than the oocytes with B type (43.8%). Embryonic developmental competence to the blastocyst stage after IVF was significantly (P < 0.05) higher in the A-type oocytes (26.3%) than in the B-type oocytes (16.9%). The levels of glutathione and reactive oxygen species were not affected by the morphological classification of the PB. In summary, these results suggest that polar body morphology could be a marker of oocyte quality after IVM. We are currently studying gene expression of each oocytes and blastocysts.

Abstract
Metabolic syndrome shows a complication at risk for cardiovascular disease and diabetes. With the high prevalence of obesity globally, the incidence of metabolic syndrome is increased. However, the basic mechanisms of metabolic syndrome are not completely known yet. Therefore, we attempted to develop large-animal model for the study of metabolic syndrome disease. Some studies have shown that constitutive overexpression of 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) in mice leads to metabolic syndrome. Therefore, we tried to produce the 11β-HSD1 gene overexpressed pig by somatic cell nuclear transfer (SCNT). First, we established 11β-HSD1 overexpressed cells for the preparation of the transgenic (TG) donor cells. Porcine fetal fibroblasts were transfected with cytomegalovirus vector that included the porcine 11β-HSD1 gene. The 11β-HSD1-TG cell was injected into the enucleated ooplasm to produce 11β-HSD1-TG cloned embryos. In total, 833 TG porcine SCNT embryos (TG-SCNT embryos) were made. Of these, 155 TG-SCNT embryos were cultured in procine zygote medium-3 to evaluate the in vitro developmental potential of TG-SCNT embryos. Among these porcine SCNT-TG embryos, 109 embryos (70.3%) were cleaved at 48 h. On Day 7, 31 transgenic porcine SCNT embryos (20.0%) developed to the blastocyst stage. The remaining 678 TG-SCNT embryos were transferred to 6 surrogates (average 113 embryos per surrogate). On 25 days after embryo transfer, 2 surrogates were diagnosed as pregnant (pregnancy rate, 33.3%). On Day 114, we obtained 9 live piglets and 3 stillborn piglets from 2 surrogates. By PCR analysis, we confirmed that 1 live piglet and 2 stillborn piglets were integrated with 11β-HSD1 gene. We succeeded to obtain TG piglets at sixth trials, and for the re-cloning by SCNT, a stable cell line transfected with the 11β-HSD1 gene was established from a TG cloned piglet. This study presents new possibilities for large-animal model development for the study of metabolic syndrome disease.
