Abstract
Certain innovative technologies applied to medical product development require novel evaluation approaches and/or regulations. Horizon scanning for such technologies will help regulators prepare, allowing earlier access to the product for patients and an improved benefit/risk ratio. This study investigates whether citation network analysis and text mining of scientific papers could be a tool for horizon scanning in the field of immunology, which has developed over a long period, and attempts to grasp the latest research trends. As the result of the analysis, the academic landscape of the immunology field was identified by classifying 90,450 papers (obtained from PubMED) containing the keyword “immune* and t lymph*” into 38 clusters. The clustering was indicative of the research landscape of the immunology field. To confirm this, immune checkpoint inhibitors were used as a retrospective test topic of therapeutics with new mechanisms of action. Retrospective clustering around immune checkpoint inhibitors was found, supporting this approach. The analysis of the research trends over the last 3 to 5 years in this field revealed several candidate topics, including ARID1A gene mutation, CD300e, and tissue resident memory T cells, which shows notable progress and should be monitored for future possible product development. Our results have demonstrated the possibility that citation network analysis and text mining of scientific papers can be a useful objective tool for horizon scanning of life science fields such as immunology.

Enhancement of the late Na+ current (INa,late) increases arrhythmia propensity in the heart, while suppression of the current is antiarrhythmic. GS-458967 (GS) is an agent considered to be a selective blocker of INa,late. In the present study, effects of GS967 on INa,late, on L-type calcium current (ICaL), and on action potential (AP) morphology were studied in canine ventricular myocytes by using conventional voltage clamp, action potential voltage clamp and sharp microelectrode techniques. These effects of GS were compared to tetrodotoxin (TTX) and to the class I/B antiarrhythmic compound mexiletine.
GS (1 μM), mexiletine (40 μM) and TTX (10 μM) dissected largely similarly shaped inward currents under action potential voltage clamp conditions. In case of GS and mexiletine, the amplitude and integral of this inward current was significantly smaller when measured in the presence of 1 μM nisoldipine, while no difference was observed in case of TTX. Under conventional voltage clamp conditions, INa,late was significantly reduced by 1 μM GS and 40 μM mexiletine (about 79% and 63% reduction of current integrals, respectively). The integral of ICa,L was moderately but significantly decreased by both drugs (reduction of 9% and 14%, respectively). These changes were associated with a faster inactivation of ICa,L.
Drug effects on early Na+ current (INa,early) were assessed by analyzing the maximal rate of depolarization (V + max) in multicellular preparations. Both GS and mexiletine showed fast onset and offset kinetics: 110 ms and 289 ms offset time constants, respectively, as determined from V + max measurements in right ventricular papillary muscles, while the onset kinetics was characterized by 5.3 AP and 2.6 AP lengths, respectively, at 2.5 Hz.
Effects on beat-to-beat variability of AP duration (APD) was studied in isolated myocytes. Short-term variability was significantly decreased by both GS and mexiletine (average reduction of 42% and 24%, respectively) while they caused similar shortening of the APD.
The electrophysiological effects of GS are similar to those of mexiletine, but with a somewhat faster offset kinetics of V + max block. However, since GS reduced V+ max and INa,late in the same concentration, the currently accepted view that GS that selectively blocks INa,late has to be questioned and it is suggested that GS should be classified as a class I/B (or I/B + IV) antiarrhythmic agent.

Abstract
Enhancement of the late Na+ current (INaL) increases arrhythmia propensity in the heart, while suppression of the current is antiarrhythmic. GS967 is an agent considered as a selective blocker of INaL. In the present study, effects of GS967 on INaL and action potential (AP) morphology were studied in canine ventricular myocytes by using conventional voltage clamp, action potential voltage clamp and sharp microelectrode techniques. The effects of GS967 (1 µM) were compared to those of the class I/B antiarrhythmic compound mexiletine (40 µM). Under conventional voltage clamp conditions, INaL was significantly suppressed by GS967 and mexiletine, causing 80.4 ± 2.2% and 59.1 ± 1.8% reduction of the densities of INaL measured at 50 ms of depolarization, and 79.0 ± 3.1% and 63.3 ± 2.7% reduction of the corresponding current integrals, respectively. Both drugs shifted the voltage dependence of the steady-state inactivation curve of INaL towards negative potentials. GS967 and mexiletine dissected inward INaL profiles under AP voltage clamp conditions having densities, measured at 50% of AP duration (APD), of −0.37 ± 0.07 and −0.28 ± 0.03 A/F, and current integrals of −56.7 ± 9.1 and −46.6 ± 5.5 mC/F, respectively. Drug effects on peak Na+ current (INaP) were assessed by recording the maximum velocity of AP upstroke (V+max) in multicellular preparations. The offset time constant was threefold faster for GS967 than mexiletine (110 ms versus 289 ms), while the onset of the rate-dependent block was slower in the case of GS967. Effects on beat-to-beat variability of APD was studied in isolated myocytes. Beat-to-beat variability was significantly decreased by both GS967 and mexiletine (reduction of 42.1 ± 6.5% and 24.6 ± 12.8%, respectively) while their shortening effect on APD was comparable. It is concluded that the electrophysiological effects of GS967 are similar to those of mexiletine, but with somewhat faster offset kinetics of V+max block. However, since GS967 depressed V+max and INaL at the same concentration, the current view that GS967 represents a new class of drugs that selectively block INaL has to be questioned and it is suggested that GS967 should be classified as a class I/B antiarrhythmic agent.

Abstract
Abstract
Introduction
Early identification of high-risk patients is the cornerstone of managing patients with acute myocardial infarction (AMI). Age Shock index (ASI; age multiplied by the ratio of heart rate/systolic blood pressure) has been reported to be similar to Global Registry of Acute Coronary Events (GRACE) risk score for predicting mortality in patients with AMI. However, prognostic impacts of prehospital ASI (pre-ASI) in patients with AMI remain unknown.
Methods
We analyzed of 2578 AMI patients who underwent emergency primary percutaneous coronary intervention (PCI) from January 2013 to March 2018, using data from Mie ACS Registry, a prospective and multicenter registry in Japan. Pre-ASI was recorded by emergency medical services at the first contact with the patient before admission, and in-hospital ASI (in-ASI) was recorded prior to PCI at admission. The primary end point was defined as all-cause death.
Results
Median follow-up duration was 753 days (497–838 days). All-cause death was observed in 230 (8.9%) patients. The ROC-AUC (Receiver operating characteristic-area under the curve) of pre-ASI for all- cause death was 0.76 (p<0.001), which was similar to that of in-ASI (0.78, p<0.001) (p=0.25 for pre-ASI versus in-ASI). The cut-off value for pre-ASI and in-ASI was for the prediction of all-cause death was both 45 with a sensitivity of 0.66 and a specificity of 0.78, with a sensitivity of 0.68 and a specificity of 0.76 respectively. According to the Kaplan-Meier survival analysis by combination of pre-ASI≥45 and in-ASI≥45, the patients with pre-ASI≥45 and in-ASI≥45 showed significantly higher all-cause mortality compared to the patients with pre-ASI≥45 and in-ASI<45, the patients with pre-ASI<45 and in-ASI≥45, and the patients with pre-ASI<45 and in-ASI<45 (p<0.001) (Figure). The addition of pre-ASI≥45 to in-ASI≥45 (global chi-squared score: 205) resulted in a significantly increased global chi-squared score, suggesting the incremental prognostic value of pre-ASI (267; p<0.001). Multivariate cox proportional hazard regression analysis for all-cause mortality demonstrated pre-ASI≥45 was a significant independent predictor (HR: 4.86; 95% CI: 3.36 to 7.02, p<0.001). It was strongest predictor compared to left ventricular ejection fraction<40% (HR: 2.45; 95% CI 1.67 to 3.58, p<0.001), hemodialysis (HR: 3.45; 95% CI 1.66 to 7.17, p=0.001), door to balloon time>90 minutes (HR: 1.66; 95% CI 1.18 to 2.34, p=0.004).
Conclusions
High pre-ASI predict increase mortality and assessment of both high pre-ASI and high in-ASI enhance risk stratification in patients with AMI. Early recognizing high pre-ASI may help us make better strategies and improve prognosis for high-risk AMI patients.

Abstract
Abstract
Background
Although patients with acute myocardial infarction (AMI) complicated by cardiogenic shock, morbidity and mortality remain high even with early revascularization and modern intensive care.
Culprit artery and prognosis were associated in patients with acute myocardial infarction.
Purpose
Evaluation of short- and long-term prognosis of AMI with cardiogenic shock by right coronary artery (RCA) and left coronary artery (LCR)
Method
We investigated 3400 AMI patients (age 68.8±12.7 y.o.) were enrolled from Mie ACS registry. They were divided into 4 groups according to the culprit artery and presence or absence of cardiogenic shock: RCA without shock n=1114, RCA with shock n=74, LCA without shock n=2028, LCA with shock n=184. Primary endpoint was defined as all-cause mortality.
Results
During the median follow-up periods with 743 days, 12.6% of the patients experienced all-cause death. RCA and LAC with shock groups demonstrated significantly higher in-hospital mortality compared to groups without shock (p<0.001, Figure 1A). Interestingly, after discharge, LCA with shock group showed significant higher all-cause mortality compared with other 3 groups. Surprisingly, RCA with shock group showed similar favorable prognosis to that of without shock groups (Figure 1B). Multivariate analyses for after discharge mortality showed that LCA with shock group was strongest independent poor prognostic factor with hazard ratio of 2.3 (95% CI 1.4–3.7), but RCA with shock group was not.
Conclusion
Association of cardiogenic shock is the hazardous risk factor for cases with AMI, especially LCA infarction. Surprisingly, RCA AMI cases with shock showed favorable prognosis as well as AMI without shock.

Abstract
Collagenofibrotic glomerulonephropathy (CFGN) is characterized by the deposition of type III collagen within the mesangial matrix and the absence of mesangial cell proliferation. A case of CFGN in a 2.7-year-old female cynomolgus macaque was investigated in the present study. Clinically, the animal was shown to have severe systemic edema along with hypoproteinemia. At necropsy, the kidneys were swollen and pale. The glomerular lesions were characterized by massive diffuse and global accumulation of fibrous materials in the mesangial areas. Neither mesangial cell proliferation nor changes in other organs were found. The fibrous materials were confirmed by the results of immunohistochemical and electron microscopic findings to consist mainly of randomly arranged, curve-shaped, twisted, and entwined type III collagen. This is the first case report of CFGN in nonhuman primates to date.

Abstract
BACKGROUND Archery related injuries, such as shoulder impingement syndrome are caused by repeated motion of the shoulder. The aim of this study was to analyze differences in the shoulder kinematics and the associated muscle activity between archers with shoulder impingement and uninjured archery players. METHODS Thirty male archers, who were divided into an impingement group and an uninjured group, were included in this study. The angle of scapular elevation, shoulder joint abduction, horizontal extension, and elbow joint flexion as well as the electromyographic activity of the upper trapezius, lower trapezius, deltoid middle, deltoid posterior, biceps brachii, and triceps brachii muscles at the point of stabilization during shooting were measured. Variables differing between impingement and uninjured groups were identified, and a stepwise regression analysis was performed to identify a combination of variables that effectively impingement syndrome. RESULTS The results indicated that the angle of scapular elevation was significantly greater than that uninjured group (P<0.05). The angle of horizontal extension in the impingement group was significantly smaller than that in the uninjured group (P<0.05). The angle of elbow flexion in the impingement group was significantly smaller than that in the uninjured group (P<0.05). The levels of upper trapezius and deltoid middle muscle activity were significantly higher in the impingement group, while the level of lower trapezius muscle activity was significantly lower (P<0.05) when compared to the uninjured group. The impingement group had a greater angle of scapular elevation, smaller angle of horizontal extension, smaller angle of elbow flexion, higher the levels of upper trapezius, lower the levels of lower trapezius, higher deltoid middle muscle activity and higher UT/LT ratio (all differences were significant). A logistic model for predicting impingement syndrome showed that UT/LT ratio was significantly related impingement syndrome (P<0.05). CONCLUSION The authors concluded that archers with shoulder impingement syndrome exhibit different kinematics and muscle activity compared to uninjured archers. Therefore, in order to prevent shoulder joint impingement during archery, training is necessary what can make lower trapezius muscle activity increased to decrease the UT/LT ratio.

Abstract
BACKGROUND AND PURPOSE IL-31, which is described as a pruritogenic cytokine, is linked to the itching that is associated with allergic and non-allergic eczema, but the precise pruritogenic mechanism of IL-31 and its potential as a therapeutic target for atopic dermatitis (AD) have not been determined. EXPERIMENTAL APPROACH We investigated the effects of existing drugs on the scratching behaviour induced by an i.v. injection of IL-31 to clarify whether IL-31 induced pruritus indirectly. In addition, we studied the effects of an anti-IL-31 receptor α subunit (anti-IL-31 receptor α) neutralizing antibody on chronic pruritus-inducing dermatitis in an AD-like model to determine whether IL-31 not only induces scratching behaviour, but is also the causative factor in an AD phenotype. KEY RESULTS The scratching behaviour induced by an i.v. injection of IL-31 was inhibited by pretreatment with an anti-IL-31 receptor α-neutralizing antibody. In contrast, it was not inhibited significantly by a non-sedative antihistamine (terfenadine), immunosuppressants (dexamethasone and tacrolimus), or a μ-opioid receptor antagonist (naloxone). The anti-IL-31 receptor α-neutralizing antibody reduced the ear swelling and dermatitis score in a chronic pruritus-inducing AD-like model. Moreover, treatment with the anti-IL-31 receptor α-neutralizing antibody showed therapeutic effects on the dermatitis even if it was injected after the disease had developed. CONCLUSIONS AND IMPLICATIONS Anti-IL-31 receptor α is a potential novel therapeutic approach for escaping from the itch-scratch cycle and also a treatment for dermatitis in AD.

Abstract
We report on a light-dispersing device consisting of two transmission gratings and a waveplate. The gratings separate two orthogonal polarization components of light incident at the Bragg angle. The waveplate, which is sandwiched between the gratings, functions as a polarization converter for oblique light incidence. With these optical parts suitably integrated, the resulting device efficiently diffracts unpolarized light with high spectral resolution. Using coupled-wave theories and Mueller matrix analysis, we constructed a device for a wavelength range of 680±50 nm with a 400 nm grating period. From the characterization of this optical device, we validated the proposed polarization-independent, light-dispersing concept.

Abstract
Condylar regeneration with the use of functional appliances after condylectomy has been validated. However, the process during treatment remains unclear. In this study, we evaluated the condylar regeneration process and then examined mandibular growth and masticatory muscle activity after regeneration in growing rats. Seventy-five male Wistar rats aged 4 weeks were equally divided into 3 groups: unilateral condylectomy group, unilateral condylectomy + appliance group, or control group. The use of a functional appliance following condylectomy promoted mandibular growth and regeneration of the condyle 1 week after condylectomy. Condyle regeneration showing normal morphology was finally achieved 8 weeks after condylectomy. Asymmetrical masticatory muscle activity was observed after condylectomy. However, the use of a functional appliance produced symmetrical masticatory muscle activity. These results indicate a favorable regeneration process in the condylectomized area due to the use of a functional appliance. In addition, due to condylar regeneration, symmetrical masticatory muscle activity was achieved.

Abstract
Since the neuroradiological features of patients with 22q11.2 deletion syndrome are not well-understood, examinations using functional imaging were performed in this study. Brain magnetic resonance imaging (MRI) and 1H-magnetic resonance spectroscopy (MRS) were performed using a clinical 3-Tesla MR imager in 4 patients with 22q11.2 deletion syndrome (2 boys and 2 girls; aged 2-6 years.) and 20 age- and sex-matched healthy control subjects. Furthermore, interictal 123I-iomazenil (IMZ) single photon emission computed tomography (SPECT) was examined in 2 of the 4 patients. Among the 4 patients with 22q11.2 deletion syndrome, 2 patients showed polymicrogyria and 1 patient showed agyria. Those patients with brain malformations also showed abnormal brain artery patterns and decreased accumulation of IMZ in 123I-IMZ SPECT. Although all 4 patients showed epileptic discharges in their electroencephalograms (EEG), one patient with polymicrogyria had no seizure episodes. Decreases in γ-aminobutyric acid (GABA) corresponding to the areas of polymicrogyria and/or epileptic discharges in EEG were shown in all patients except for the patient with agyria. Although consistent evidence was not seen in patients with 22q11.2 deletion syndrome in this study, brain malformations and disturbances of the GABAergic nervous system would be underlying mechanisms of the neurodevelopmental abnormalities in this syndrome.

Abstract
A case is reported of a patient with only isolated conduction abnormalities of the His-Purkinje system with no identifiable myocardial or valvar dysfunction, leading to "clockwise" and "counterclockwise" bundle branch re-entrant ventricular tachycardias (BBRVTs). The electrophysiological study showed infra-Hisian conduction system disease and two different inducible wide QRS complex tachycardias. Neither right bundle branch nor left bundle branch potentials were recorded despite extensive catheter manipulation. However, these tachycardias were diagnosed as BBRVTs by using entrainment manoeuvres and comparing the HV intervals during both sinus rhythm and the tachycardias. These tachycardias were eliminated by catheter ablation of the right bundle branch, using the morphology of the local electrograms and anatomical findings.

Abstract
This study aimed to investigate the changes in apoptosis in the placenta and decidua of pregnant mice lacking the prostaglandin F receptor. Mouse placentae were removed from fetuses on days 10-23 of pregnancy. Apoptotic cells were examined by a DNA fragmentation assay and the terminal deoxynucleotidyl transferase-mediated dUDP nick end-labelling (TUNEL) technique. The placenta and decidual weight increased before day 18 and 14 of pregnancy, and then decreased with gestational day. After day 19, the fetuses gradually died in the uterus. All fetuses died in the uterus on day 23 of pregnancy. The number of apoptosis was not significantly different between wild type and FP-deficient mice before day 18 of pregnancy by DNA fragmentation and TUNEL staining. The DNA fragmentation was always more pronounced in decidual tissue on each day of pregnancy. DNA laddering on placentae was more extensive on day 22 than day 18. In placenta, most TUNEL-positive cells were detected in trophoblast and stromal cells. A higher intensity of apoptotic cells was in the decidual basalis. The main area was the centre of the decidual basalis, and was in decrease toward to margin of placenta. The index of TUNEL positive cells increased as gestation progressed toward termination. Especially, it was prominent in the placentae on day 22 compared with that day 18 of pregnancy. The increased TUNEL-positive staining in syncytiotrophoblast surface was found in placenta at post-term, compared with those at term. Apoptosis may provide insights into both normal placental development and placental dysfunction during an abnormal pregnancy from post-term pregnancy.

Abstract
OBJECTIVE The effects of pretreatment with ONO-4007, a lipid A analog, on cutaneous plasma leakage induced by ONO-4007, lipopolysaccharide (LPS) and inflammatory mediators were investigated. MATERIAL Male ddY strain mice. TREATMENT Mice were pretreated with ONO-4007 (up to 6 mg/kg i.p.), 0-24 h prior to plasma leakage study. METHODS Plasma extravasation was determined by dye leakage. RESULTS Systemic ONO-4007 (6 mg/kg i. p.) pretreatment for 2 to 12 h inhibited plasma extravasation in the mouse skin elicited by ONO-4007 and LPS. The inhibition was dose-dependent. Plasma leakage induced by platelet-activating factor (PAF), histamine and 5-hydroxytryptamine (5-HT) was also inhibited by ONO-4007 pretreatment. Plasma corticosterone levels increased 2 and 4 h after systemic ONO-4007 (6 mg/kg) administration and returned to the control level 24 h later. Adrenalectomy and metyrapone but not propranolol reversed the inhibition by ONO-4007 pretreatment of LPS-induced plasma leakage. CONCLUSIONS A single injection of ONO-4007 in mice induced transient tolerance to plasma leakage elicited by LPS, ONO-4007 and inflammatory mediators. Endogenous corticosterone, at least in part, plays a role in the development of tolerance.

Abstract
Neuroprotective mechanisms of hypothermia have not been clearly established especially in the immature brain. To investigate the effect of hypothermia on cell death and cell survival signal pathways, we studied caspase-3-like activity and activation of Akt in a rat model of neonatal hypoxic-ischemic (H-I) brain injury. Seven-day-old rats underwent a combination of left common carotid artery ligation and exposure to 8% O(2) for 1-h (n=32). During recovery, the body temperature was reduced to 30 degrees C for 24 h in 16 animals, but was kept at 37 degrees C in 16 animals. Post-ischemic hypothermia was shown to diminish the caspase-3-like activity compared to normothermia at 6 and 24 h after H-I. Phospho-Akt was increased during the early reperfusion period after H-I in the normothermia group, but hypothermia rather decreased this enhanced phosphorylation of Akt following H-I. These results indicated that hypothermia may have some depressant effects on both cell death and cell survival signal pathways, and that Akt conceivably may not play a major role in the neuroprotective effect of hypothermia in the immature brain.

Abstract
BACKGROUND The concurrent use of amiodarone and warfarin inhibits metabolism of S-warfarinby cytochrome P450 (CYP) 2C9, thereby increasing the anticoagulant effect of warfarin. Amiodarone primarily inhibits CYP1A2 and CYP3A4, and desethylamiodarone primarily inhibits CYP2C9. We investigate whether a relationship exists between the plasma concentration of desethylamiodarone and anticoagulation when amiodarone is administered to patients receiving warfarin therapy. METHODS AND RESULTS The correlation between the plasma concentration of either amiodarone or desethylamiodarone, and prolongation of prothrombin time-international normalized ratio/dose of warfarin (Delta INR/Dose) on day 7 of amiodarone administration was studied in 25 patients (22-74 years old) with structural heart disease and refractory arrhythmias receiving stable warfarin therapy. RESULTS No correlation was found between the plasma concentration of amiodarone and Delta INR/Dose, but a correlation was found between the plasma concentration of desethylamiodarone and Delta INR/Dose. CONCLUSIONS It was suggested that inhibition of CYP2C9 by desethylamiodarone, the active metabolite of amiodarone, plays an important role in the interaction of warfarin and amiodarone.

Abstract
Fructose-1, 6-bisphosphate (FBP) has a neuroprotective effect in neonatal and adult rats. The purpose of this study was to examine the effects of FBP on hippocampal neuronal damage in fetal sheep asphyxiated by 10 min of complete umbilical cord occlusion. Thirteen fetal sheep at 124 days of gestation were surgically instrumented with catheters. Cardiorespiratory parameters were monitored, and biochemical analyses were performed with the blood samples. During the insult seven fetuses were given FBP (500 mg/kg) and six were given iso-osmotic saline, and hippocampal neuronal damage was examined histologically and scored. Cardiorespiratory changes were the same in both groups, and there was no neuroprotective effect of FBP in this study. However the decrease of serum total Ca level implied the Ca- chelating effect of FBP.

Abstract
The effects of hypothermia on caspase-3 activation were investigated in the newborn rat brain after hypoxia-ischemia (HI). Intense caspase-3 activation was observed in the control brains after HI, but this activation was significantly reduced by postischemic hypothermia. These findings suggest that the inhibition of caspase-3 activation may be an interventional point underlying the neuroprotective effect of hypothermia in neonates.

Abstract
Anti-inflammatory effects of cyclic AMP elevating agents were examined in a mouse model of lipopolysaccharide (LPS)-induced microvascular permeability change. Vascular permeability on the back skin was measured by the local accumulation of Pontamine sky blue (PSB) after subcutaneous injection of LPS (400 microg site-1) from Salmonella typhimurium. Dye leakage in the skin was significantly increased 2 h after injection of LPS. This LPS-induced dye leakage was suppressed by phosphodiesterase inhibitors, including pentoxifylline (160 mg kg-1), milrinone (5 - 10 mg kg-1), rolipram (0.5 - 10 mg kg-1) and zaprinast (5 - 10 mg kg-1). The dye leakage was also inhibited by beta-adrenoceptor agonists, including isoproterenol (0.5 - 5 mg kg-1) and salbutamol (0.05 - 5 mg kg-1), an adenylate cyclase activator, forskolin (5 mg kg-1), and a cell permeable cyclic AMP analogue, 8-bromo-cyclic AMP (8-Br-cAMP, 10 mg kg-1). LPS caused a transient increase in serum TNF-alpha level peaking at 1 h after the injection. This increase in serum TNF-alpha was completely blocked by a pretreatment with pentoxifylline (160 mg kg-1), milrinone (5 mg kg-1), rolipram (1 mg kg-1), zaprinast (10 mg kg-1), salbutamol (0.5 mg kg-1), forskolin (1 mg kg-1) and 8-Br-cAMP (10 mg kg-1). LPS caused an increase in serum IL-1alpha level peaking at 3 h after injection. This increase in serum IL-1alpha was not significantly suppressed by the cyclic AMP elevating agents. Our study suggests that cyclic AMP elevating agents attenuate LPS-induced microvascular permeability change by suppressing TNF-alpha up regulation.

Abstract
To evaluate brain dysfunction in autism, proton magnetic resonance spectroscopy (1H-MRS) was performed for 29 autistic patients (5-15 y.o.) and 19 normal children (6-14 y.o.). We obtained magnetic resonance (MR) spectra of the left and right amygdaloid-hippocampal regions and the left cerebellar hemisphere with a STEAM sequence (TR = 5000 ms, TE = 18 ms). In addition to the evaluation of signal intensity ratios, the absolute concentration of three major metabolites (N-acetylaspartate [NAA], creatine/phosphocreatine [Cr] and choline-containing substances [Cho]) was quantified by an internal reference method using unsuppressed tissue water. Although no abnormal MR images were found in the three regions examined, the signal intensity and the concentration of NAA in the left amygdaloid-hippocampal region and the left cerebellar hemisphere were reduced significantly in autistic patients compared to normal children. We speculated that this decrease in NAA reflected neuronal loss, immaturity or hypofunction in these regions. The results of our study were in agreement with those of previous studies on autism, one by neuropathological methods and the other using a single photon emission computed tomography with 99mTc HMPAO. Disorders of the amygdaloid-hippocampal region and cerebellum are considered to play an important role in the characteristic cognitive and emotional dysfunction in autism. 1H-MRS is a valuable tool to clarify the pathophysiology of autism.

Abstract
A novel platinum complex, compound C, developed as an antitumor agent, was intravenously administered at 10 mg/kg/day to 6-week-old and 8-week-old rats. After 4 weeks of administration to the former, testicular enlargement was observed at a similar incidence as testicular atrophy and dilatation or atrophy of the seminiferous tubules was observed. Degeneration/necrosis of the seminiferous epithelium, decrease of seminiferous epithelium, formation of multinucleated giant cells, and vacuolar degeneration of Sertoli cells were also seen. These lesions were more marked in seminiferous tubules with atrophy than in those without atrophy. After 2-week administration to 8-week-old rats, slight initial-phase findings such as dilatation of seminiferous tubules and degeneration/necrosis of the seminiferous epithelium were noted in all rats. In rats administered 20 mg/kg/day, for which the administration period was shortened to 1 week due to marked weight loss, very slight initial lesions were similarly observed. However, these lesions were not easy to detect in these rats. Following single administration of a sublethal dose (80 mg/kg), testicular lesions were clearly observed 14 days after administration, but the incidence and grade of lesions were very low at 7 days. In conclusion, testicular toxicity of compound C can be clearly detected after 2-week administration, although the progression of lesions differed from the case with 4-week administration.

Abstract
Uterine contractions at parturition depend upon a variety of factors, including gamma-aminobutyric acid (GABA)-ergic stimulation. A new subunit of the GABA(A) receptor, pi, has recently been identified as being particularly abundant in the rat uterus. Reduced derivatives of progesterone, such as the 3alpha,5alpha-reduced derivative termed allopregnanolone, modulate GABA(A) receptor activity and neuronal inhibition by modulating the frequency and duration of GABA(A) channel opening. This modulation depends on the specific subunit composition of the GABA(A) receptor. In particular, assembly of recombinant pi and delta GABA(A) receptor subunits into a functional GABA(A) receptor have been reported to reduce sensitivity to allopregnanolone. As allopregnanolone works through the GABA(A) receptor to reduce uterine contraction, we hypothesized that incorporation of the pi-subunit into this receptor in the uterus might change the sensitivity of the GABA(A) receptor to allopregnanolone and modulate parturition. We therefore determined the expression of GABA(A) receptor subunit messenger RNAs (mRNAs) in rat uteri from various gestational ages and determined the physiological properties of the receptors. GABA(A) pi-subunit mRNA abundance was constant throughout gestation, but decreased at the onset of labor. Other GABA(A) subunits fluctuated differently during pregnancy: GABA(A) alpha(1)-subunit mRNA expression increased, whereas alpha(2)- and delta-subunit mRNA expression decreased during pregnancy, and beta(3)-subunit mRNA only appeared on postpartum day 1. We determined how allopregnanolone affected the binding of muscimol, a ligand for the GABA(A) receptor, to rat uterine GABA(A) receptors throughout pregnancy. Allopregnanolone caused the greatest increase in muscimol binding to uterine GABA(A) receptors at 19.5 days gestation and the least increase during labor, a time when pi and alpha(1) receptor subunit mRNA concentrations were low, and delta and alpha(2) receptor subunit mRNA concentrations were high. Thus, the subunit composition of the GABA(A) receptor differs in rat uteri throughout gestation. These changes may also affect the sensitivity of the GABA(A) receptor to allopregnanolone and thus contribute to the regulation of parturition.

Abstract
One hundred and eighty-nine patients who underwent digestive tract surgery were studied to investigate risk factors for the development of postoperative hypertension. We examined factors related to maximum postoperative systolic blood pressure and postoperative hypertensive urgency, a sign of postoperative hypertension. Data collected included blood pressure, age, sex, body mass index (BMI), medical history, total water balance and grade of surgical stress. Maximum postoperative systolic blood pressure and incidence of postoperative hypertensive urgency were the dependent variables. Mean preoperative systolic blood pressure, age and BMI were significantly related to maximum postoperative systolic blood pressure and postoperative hypertensive urgency. In addition, the grade of surgical stress was significantly related to maximum postoperative systolic blood pressure. In analyses of multiple variables, the adjusted odds ratio for postoperative hypertensive urgency was 1.16 for every 1 mmHg increase in mean preoperative systolic blood pressure, 1.05 for every 1 year increase in age and 0.82 for every 1 kg/m2 increase in BMI. These findings may have important clinical implications for the prevention of postoperative hypertension.

Abstract
OBJECTIVE The immunological mechanisms that support persistence and proliferation of ectopic endometrial implants within the peritoneal cavity of women with endometriosis are unknown. Inhibition of natural killer (NK) and cytotoxic T-cell function has been proposed as a mechanism. We tested the hypothesis that expression of a nonclassical major histocompatibility antigen, HLA-G, might explain the local immunosuppression associated with ectopic endometrium. DESIGN Nested case-control study of women with and without laparoscopic evidence of endometriosis. SETTING Reproductive endocrinology clinic at a university hospital. PATIENT(S) Peritoneal fluid specimens from 10 women with revised AFS stage I-IV endometriosis and from 10 age-matched normal controls without laparoscopic evidence of endometriosis were tested for the presence of HLA-G protein. Endometriosis and normal endometrial biopsies from four patients were used to prepare stromal cell cultures directly evaluated for HLA-G protein. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The expression of HLA-G in peritoneal fluid, tissue, and cell cultures was determined by immunoblotting with a specific monoclonal antibody. RESULT(S) HLA-G protein was not detectable in peritoneal fluid specimens of endometriosis patients or controls. Moreover, ectopic and normal endometrial tissues and stromal cells did not express HLA-G. CONCLUSION(S) Immune cell inhibition in endometriosis must be mediated by factors other than HLA-G.

Abstract
Approximately half of all patients with chronic hepatitis C show an initial biochemical response to interferon, but only 15% to 20% of patients achieve a sustained response. We studied the efficacy of retreatment with interferon for patients with chronic hepatitis C who showed transient biochemical responses to initial treatment. Thirty patients who relapsed were retreated 1 to 52 months (median 14) after the end of initial treatment, according to the previously used regimens. The responses were correlated with the pre-retreatment patient data. The liver histologic grades, compared with those found before the initial treatment, were better in eight (27%) patients but worse in six (20%), whereas the fibrosis stage was improved in five (17%) but worsened in eight (27%). All patients displayed end-of-retreatment biochemical responses. Of the 30 patients, 10 (33%) achieved sustained aminotransferase normalization and serum hepatitis C virus (HCV) RNA clearance, but the remaining 20 patients showed relapse within 1 year after cessation of retreatment. Univariate analysis associated the sustained response with low pre-retreatment viral loads (0.8 +/- 0.7 MEq/mL vs. 9.1 +/- 6.5 MEq/mL; p = 0.006), short treatment intervals (13 +/- 13 months vs. 22 +/- 14 months; p = 0.031), and low histologic grades (1.3 +/- 0.7 vs. 1.9 +/- 0.7; p = 0.039). However, multivariate analysis indicated that only the pre-retreatment viral load was predictive of the sustained response (p = 0.049). These findings suggest that transient responders to interferon are likely to respond to retreatment but the achievement of a sustained response depends on the HCV viral load before retreatment.

Abstract
UNLABELLED The purpose of this study was to examine the electrophysiological determinants of the elimination of recurrent atrioventricular nodal reentrant tachycardia (AVNRT) despite the persistence of dual AV nodal pathway physiology or single echo beats after ablation procedures. The study included 26 patients with common AVNRT who had undergone successful ablation treatment and no long-term recurrence of AVNRT. The slow pathway potential was targeted, and the endpoint of ablation was one echo during atrial extrastimulus testing (ET) with isoproterenol. Persistent dual pathways physiology or single echoes were present in 12 patients (group I) and absent in 16 (group II) after ablation. The number of anterograde AV nodal pathways and maximum AH interval (Max AH) during ET were measured before and after ablation, and ventriculoatrial conduction during ventricular pacing was examined. RESULTS (1) multiple AV nodal pathways were more frequently observed in group I than in group II (50.0% vs 7%, P < 0.05); (2) Max AH decreased significantly after ablation in both groups (309 +/- 157 vs 171 +/- 53 ms in group II; P < 0.01, and 409 +/- 65 vs 274 +/- 86 ms in group I; P < 0.001); and (3) retrograde dual pathway conduction was more common in group I than in group II. These data suggest the presence of nonuniform conductive properties of the AV node in group I and that ablation targeting the slow pathway potential prevents recurrences of AVNRT by eliminating the pathway with the longest conduction time.

Abstract
1. Endotoxin shock is accompanied by an increase in peripheral vascular permeability. It has been postulated that most biological activities of LPS are derived from lipid A moiety. Here we examined the effect of lipid A analogue ONO-4007 in increasing vascular permeability and the possible mediators in mouse skin by a dye leakage method. 2. Subcutaneous injection of ONO-4007 (1 - 2 mg site(-1)) induced a dose-dependent increase in vascular permeability which was evident after 120 min. 3. ONO-4007-induced dye leakage was significantly attenuated by pretreatments with anti-tumour necrosis factor-alpha (TNF-alpha) and anti-interleukin-1alpha (IL-1alpha) antibodies, but not with indomethacin (5 mg kg(-1)) or diphenhydramine (10 mg kg(-1)). ONO-4007-induced dye leakage was significantly inhibited by a pretreatment with N(G)-nitro-L-arginine methyl ester (L-NAME) (10 mg kg(-1)) but not with aminoguanidine (50 mg kg(-1)). In inducible nitric oxide synthase (iNOS)-deficient mice, ONO-4007 significantly increased the dye leakage, while ONO-4007 dilated rat thoracic aortic rings pre-contracted with phenylephrine, and the L-NAME pretreatment inhibited the dilation. 4. Thus, TNF-alpha, IL-1alpha and constitutive NOSs-derived nitric oxide but not prostaglandins or histamine play a role in ONO-4007-induced increase in vascular permeability. Although ONO-4007 mimics LPS in increasing vascular permeability, mechanisms of permeability change elicited by ONO-4007 were not identical to those of LPS.

Abstract
A case of ulcerative colitis complicated by oesophageal ulcers is reported. A woman was admitted to our hospital because of exacerbations of ulcerative colitis both in 1992 (aged 15 years) and 1995 (aged 18 years). When she was admitted in 1995 she complained of bloody diarrhoea, sore throat and pain on swallowing. Oesophagogastro-duodenoscopy revealed oesophageal ulcers. Oesophageal pH monitoring (24-h) showed no evidence of gastro-oesophageal reflux disease. After the patient was treated she with oral prednisolone showed considerable improvement clinically and endoscopically. Initial dosage was 60 mg/day, and 1 week later, the dosage was gradually dropped since the patient responded favourably. The improvement of the oesophageal lesions coincided with the remission of ulcerative colitis. The oesophageal ulcers are, therefore, thought to be an extracolonic manifestation of ulcerative colitis.

Abstract
Lipoteichoic acid (LTA), the cell wall component of Gram-positive bacteria, has been shown to cause inflammatory responses comparable to lipopolysaccharide (LPS) of Gram-negative bacteria. This study examined the activity of LTA to induce dermal microvascular permeability changes in mice. Vascular permeability was assessed by extravasation of Pontamine sky blue. Subcutaneous injection of LTA (200-400 microg/site) in mice that were preinjected i.v. with the dye increased local dye leakage in the skin at 1 to 3 h. The LTA-induced dye leakage was inhibited by indomethacin, valeryl salicylate, diphenhydramine, and a platelet-activating factor antagonist but not by inhibitors of nitric-oxide synthase, cyclooxygenase-2, or guanylate cyclase or by antibodies against tumor necrosis factor-alpha or interleukin-1alpha. LTA induced comparable increases in dye leakage in inducible nitric-oxide synthase-deficient mice and wild-type controls. Pretreatment of normal mice with i.v. LTA did not confer tolerance to LTA- or LPS-induced dye leakage. In contrast, systemic LPS administration induced tolerance against subsequent challenge with LPS but not LTA. Serum corticosterone levels, which were suggested to induce tolerance, were not increased by LTA pretreatment but were increased by LPS. Thus, LTA increases dermal microvascular permeability in mice. Among the inflammatory mediators, eicosanoids, platelet-activating factor, and histamine mediate the effect of both LTA and LPS, whereas nitric oxide, tumor necrosis factor-alpha, and interleukin-1alpha may not play a major role in LTA-induced dye leakage. The difference between LTA and LPS to stimulate corticosterone may partially explain the failure of LTA to induce tolerance against vascular dye leakage.

Abstract
A 21-year-old woman had paroxysmal wide QRS tachycardia with a left bundle branch block configuration and a retrograde conducted P wave just behind the QRS complex. An electrophysiological study revealed antidromic atrioventricular tachycardia involving an atrioventricular connection with decremental conduction as the anterograde limb and normal atrioventricular node as the retrograde limb. During constant pacing from the high right atrium (HRA) at the cycle length (CL) of 600 ms, the QRS configurations were not identical to those during the wide QRS tachycardia or constant pacing at the CL of less than 500 ms. The process by which this arborized atrioventricular accessory pathway with the Mahaim fibers physiology was interrupted by radiofrequency catheter ablation is described. Radiofrequency energy was delivered to the site recording a Mahaim potential at the tricuspid annulus during constant pacing from the HRA at the CL of 429 ms. The stimulus-QRS interval gradually shortened as it reached the power plateau without changing the preexcited QRS configuration. Shortening of the conduction time over the Mahiam pathway might have resulted in changing of the propagation from a slow to fast conduction zone or acceleration in response to thermal effect in a node-like structure on the atrial insertion site.

Abstract
The role of endogenous nitric oxide (NO) and prostanoids in the increase in microvascular permeability induced by NO donors was investigated in the mouse skin by a dye leakage method. Subcutaneous (s.c.) injection of 1-hydroxy-2-oxo-3-(3-aminopropyl)-3-isopropyl-1-triazene (NOC 5), 1-hydroxy-2-oxo-3,3-bis(2-aminoethyl)-1-triazene (NOC 18) and sodium nitroprusside dose-dependently increased local dye leakage. While indomethacin inhibited the dye leakage elicited by these NO donors, N(G)-nitro-L-arginine methyl ester (L-NAME) inhibited the effect of NOC 5 and NOC 18 but not of sodium nitroprusside. These results suggest that endogenous NO, in addition to the prostanoid biosynthesis, is involved in the dermal microvascular permeability increase induced by the NOC series NO donors.
