Abstract
Background:Sarcopenia is a progressive systemic skeletal muscle disorder associated with an increased likelihood of adverse outcomes including physical disability, falls, and mortality. The muscle mass of patients with rheumatoid arthritis (RA) is lower than that of age-matched healthy individuals, and a high prevalence rate of sarcopenia has been reported1). In particular, foot deformities may increase the prevalence rate of sarcopenia because of inactivity due to foot pain on walking. Treatment with a foot orthosis (FO) can reportedly reduce pain2); however, whether a FO can resolve inactivity and sarcopenia is unclear.Objectives:To elucidate the effectiveness of a FO on physical activity and sarcopenia in patients with RA.Methods:Thirty patients with RA with foot deformities were enrolled from April 2017 to December 2019. Sarcopenia was diagnosed using the algorithm of the European Working Group on Sarcopenia in Older People, and the cut-off values of the Asian Working Group for Sarcopenia were applied. We also collected the clinical variables of patients with concurrent RA and sarcopenia who continued to use a FO for 6 months. The primary outcome was physical activity determined by the International Physical Activity Questionnaire. The secondary outcomes were foot pain measured with a visual analog scale; activities of daily living (ADL) measured with the Health Assessment Questionnaire; and body mass index, body fat percentage, and the skeletal muscle mass index measured with a body composition device. The clinical variables were compared between baseline and 6 months after continuous treatment with a FO.Results:The prevalence rate of sarcopenia was 76.6% (23/30), and nine patients with RA continued to use the FO for 6 months. Table 1 shows outcomes at baseline and after 6 months of treatment with a FO. The only clinical variable that showed a significant difference was foot pain. Physical activities, ADL, and body compositions were maintained after 6 months.Table 1.Outcomes of 6-month treatment with FOBaseline6 monthsp valuePhysical activityIPAQWalking, MET-min/weekModerate, MET-min/weekVigorous, MET-min/week132 (66, 594)0 (0, 0)0 (0, 0)594 (396, 2376)0 (0, 0)0 (0, 0)0.071.000.32Foot painVAS score4.6 (3.1, 7.4)2.8 (1.1, 4.7)0.02ADLHAQ1.5 (1.1, 2.3)1.1 (0.9, 1.5)0.07Body compositionBMI, kg/m2BFP, %SMI, kg/m221.4 (20.7, 22.7)31.1 (24.2, 37.6)5.2 (4.8, 5.3)20.7 (19.3, 22.1)32.9 (26.3, 36.5)5.2 (5.0, 5.2)0.890.820.61IPAQ: International Physical Activity Questionnaire, VAS: visual analog scale, ADL: activities of daily living, HAQ: Health Assessment Questionnaire, BMI: body mass index, BFP: body fat percentage, SMI: skeletal muscle mass indexData are presented as median (lower quartile, upper quartile)Conclusion:The prevalence rate of sarcopenia in patients with RA with foot deformities was much higher than previous reported1). However, 6 months of treatment with a FO not only reduced foot pain but also maintained physical activity and muscle mass. Physical therapy has recently been recommended for patients with inflammatory arthritis. physical activity and muscle mass of patients with RA and concurrent foot deformities may be increased by combining physical therapy with orthotic treatment.References:[1]Tada M, et al.

Abstract
UNLABELLED We compared the bone strength measured via quantitative computed tomography-based finite element method (QCT/FEM) between healthy adults with and without ossification of the posterior longitudinal ligament (OPLL). No statistically significant difference was observed in the bone strength between healthy adults with and without OPLL. Hyperostosis of the posterior longitudinal ligament in OPLL may not be associated with the systemic bone strength. INTRODUCTION Although patients with OPLL have been reportedly associated with increased level of bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA), little is known about the bone strength in OPLL subjects. The aim of this study is to investigate the bone strength measured via QCT/FEM in healthy subjects with OPLL using the medical check-up data, including whole-body CT scans. METHODS We examined 796 participants (529 men and 267 women) who underwent CT scans in a single health center between January 2008 and May 2009. We identified OPLL in whole spine and divided the subjects into two groups: non-OPLL and OPLL groups. We calculated the predicted bone strength (PBS) of the proximal femur using QCT/FEM and examined the bone mineral status of the calcaneus using quantitative ultrasound (QUS). We compared the PBS and the QUS parameters between the non-OPLL and OPLL groups. RESULTS Seventy-four subjects (9.3%; 57 men and 17 women) were diagnosed with OPLL in the whole spine. The OPLL group was significantly older than the non-OPLL group. No statistically significant difference was observed in the PBS and the QUS parameters between the non-OPLL and OPLL groups in both sexes. Furthermore, no statistically significant difference was noted in the PBS and the QUS parameters between two groups in age- and gender-matched analysis. CONCLUSIONS Our results suggest that hyperostosis of the posterior longitudinal ligament in OPLL may not be associated with bone strength and bone mineral status at the extremities.

Abstract
AIMS To evaluate the protective effects of oral administration of milk fermented with a Lactococcus strain against influenza virus (IFV) infection in a mouse model. METHODS AND RESULTS Milk fermented with exopolysaccharide-producing Lactococcus lactis subsp. cremoris (L. cremoris) FC was orally administered to BALB/c mice for 12 days. Mice were intranasally infected with IFV A/New Caledonia/20/99 (H1N1) on day 8, and survival was determined for 14 days after IFV infection. Survival rate and body weight loss after IFV infection in the L. cremoris FC fermented milk-administered group were significantly improved compared with those in the control group. In the unfermented milk-administered group, survival rate was not improved, whereas body weight loss was slightly improved compared with that in the control group. The mean virus titre in the lung of the L. cremoris FC fermented milk-administered group 3 days after infection was significantly decreased compared with that in the control group. CONCLUSIONS These results suggest that oral administration of milk fermented with L. cremoris FC protects mice against IFV infection. SIGNIFICANCE AND IMPACT OF THE STUDY These results demonstrate that oral administration of milk fermented with exopolysaccharide-producing Lactococcus strains might protect host animals against IFV infection.

Abstract
We evaluated the effect of low-intensity pulsed ultrasound stimulation (LIPUS) on the remodelling of callus in a rabbit gap-healing model by bone morphometric analyses using three-dimensional quantitative micro-CT. A tibial osteotomy with a 2 mm gap was immobilised by rigid external fixation and LIPUS was applied using active translucent devices. A control group had sham inactive transducers applied. A region of interest of micro-CT was set at the centre of the osteotomy gap with a width of 1 mm. The morphometric parameters used for evaluation were the volume of mineralised callus (BV) and the volumetric bone mineral density of mineralised tissue (mBMD). The whole region of interest was measured and subdivided into three zones as follows: the periosteal callus zone (external), the medullary callus zone (endosteal) and the cortical gap zone (intercortical). The BV and mBMD were measured for each zone. In the endosteal area, there was a significant increase in the density of newly formed callus which was subsequently diminished by bone resorption that overwhelmed bone formation in this area as the intramedullary canal was restored. In the intercortical area, LIPUS was considered to enhance bone formation throughout the period of observation. These findings indicate that LIPUS could shorten the time required for remodelling and enhance the mineralisation of callus.

Abstract
For reliable diagnosis of porcine teschovirus (PTV) infection we created an RT-PCR-based molecular strategy for serotyping that encompassed the dominant neutralizing antigenic site of PTV, followed by phylogenetic analyses of amplicons. We identified neutralizing antigenic sites of PTV-1 Talfan strain through epitope mapping of neutralizing monoclonal antibodies (MAbs), using synthetic peptides spanning the capsid proteins. All 11 MAbs obtained recognized peptides in the EF loop ("puff") of VP2 protein. Two MAbs concurrently reacted to peptides, one in the GH loop of VP1 and one in the VP1 C terminus. Three-dimensional modeling of Talfan capsid protein predicted exposure of all these sites on the virion surface in a close line centered around puff. We then designed a single pair of degenerate primers to VP2 and amplified the region of approximately 320 bp encompassing puff in 8 PTV prototype strains and 6 field isolates. Phylogenetic analyses of the puff sequences of 11 prototype strains and 34 field isolates obtained from databanks showed that all homotypic strains (both field and prototype) were always monophyletic, except for one 'untypable' Japanese strain. This RT-PCR-based strategy appears to be a reliable surrogate for serotyping and could facilitate the diagnosis and epidemiological study of PTV infection.

Abstract
Mammalian Aurora-A is related to a serine/threonine protein kinase that was originally identified by its close homology with Saccharomyces cerevisiae Ipl1p and Drosophila melanogaster aurora that are key regulators in the orchestration of mitotic events. The protein level of Aurora-A, its peak kinase activity during mitosis, and its activation have been attributed to phosphorylation. Here we show that this enzyme is an arginine-directed kinase and define its substrate specificity. We also found that Thr288 within the activation loop is a critical residue for activating phosphorylation events in vitro and that it is spatiotemporally restricted to a brief window at mitosis on duplicated centrosomes and on spindle microtubules proximal to the poles in vivo. Immunodepletion assays indicated that an upstream kinase(s) of Aurora-A might exist in mammalian cells in addition to autophosphorylation. Furthermore, human activated Aurora-A forms complexes with the negative regulator protein serine/threonine phosphatase type 1 (PP1) that was negatively phosphorylated on Thr320. Interestingly, phospho-specific Aurora-A monoclonal antibodies restrain Aurora-A kinase activity in vitro, providing further therapeutic avenues to explore.

Abstract
BACKGROUND AND AIMS Major histocompatibility complex class II deficient (Aalpha0/0) mice have decreased CD4+ T cells, making them immunologically similar to patients with acquired immunodeficiency syndrome (AIDS). Both patients with AIDS and Aalpha0/0 mice have hypertrophic gastric folds. To clarify the mechanism of gastric mucosal hyperplasia, we investigated the pathophysiology and the role of the innate immunity in the stomach of Aalpha0/0 mice. METHODS Stomachs from 1-6 month old Aalpha0/0 mice, kept under specific pathogen free conditions, were examined at 1 month intervals histologically and immunohistochemically. Gene expression of proinflammatory cytokines, Toll-like receptors (TLRs), cyclooxygenase (COX)-2, and myeloperoxidase (MPO) activity in the gastric mucosa was investigated. Serum gastrin levels and gastric acidity were measured. Bacterial culture of the stomach was performed. To clarify the roles of hypergastrinaemia in the gastric mucosa, a gastrin receptor antagonist (AG041R) was administered. RESULTS Aalpha0/0 mice had a diffusely thick corpus mucosa with infiltration of CD11b+ granulocytes and macrophages. Anti-Ki67 staining demonstrated expansion of the proliferating neck zone. Gene expression of interleukin 1beta, interferon gamma, TLR-2, TLR-4, and COX-2 were upregulated, and MPO activity was increased. Only a small amount of non-pathogenic bacteria was detected in the stomach. Serum gastrin levels and Reg-Ialpha positive cells in the gastric mucosa increased, despite normal gastric acidity. After treatment with AG041R, gastric mucosal thickness was significantly reduced. CONCLUSION Persistent activation of innate immunity in the stomach induced gastric mucosal hyperplasia through upregulation of gastrin synthesis in Aalpha0/0 mice, suggesting a pathophysiology similar to the gastric changes in patients with AIDS.

Abstract
In 1985--2002, surveillance for bovine arboviruses was conducted in Kagoshima, located in the most southern part of the main islands of Japan and known to be an area where bovine arboviral diseases have frequently been epidemic. Culicoides biting midges were collected in a cowshed by light traps. A total of 456,300 Culicoides biting midges representing 13 species were collected, and a portion of each pool of midges were tested for virus isolation. Overall, 85 isolates of six different viruses were obtained from the collected midges. The isolated viruses included two Orthobunyaviruses, Akabane and Aino viruses; three Orbiviruses, Chuzan, D'Aguliar, and Ibaraki viruses; and one unclassified virus, a bunyavirus-like virus. The viruses were most frequently isolated from Culicoides oxystoma Kieffer (85.9% of 85 isolates). Isolations of all viruses except for the bunyavirus-like virus were made from this species. Our data indicated that C. oxystoma is a potential vector for bovine arboviruses in southern Japan.

Abstract
YDA filler is an antibacterial agent that is currently in commercial dental use. In this study, we attempted to determine whether it exerts an antibacterial effect on human saliva bacteria, and to determine whether it can be used in dental materials. CFUs in 1 mL stimulated human saliva were examined using blood agar and mitis salivarius agar after immersion, with or without YDA filler. The antibacterial effect was compared with that of Ketac-Silver. Dental materials containing 5% wt YDA filler were prepared for in vitro testing on S. mutans and A. viscosus. Furthermore, we examined the in vitro cytotoxicity of experimental MMA resin containing YDA filler on HeLa cells. Human saliva bacteria and mutans streptococci showed reduced viability following exposure to YDA filler after 12 h. The concentration of silver ions released by YDA filler was below 1 ppm after 12 h. Two tested strains showed reduced viability following exposure to dental materials containing YDA filler. In another experiment, MMA resin containing YDA filler did not show cytotoxicity on HeLa cells after 24- and 48-h exposure. Thus, YDA filler may help in the development of antibacterial dental materials, such as composite resin, glass-ionomer or temporary cement.

Abstract
Ten multiparous lactating Japanese Black cows (beef breed) were used to evaluate the effects of bovine growth hormone-releasing hormone (GHRH) analog on milk yield and profiles of plasma hormones and metabolites. The cows received 2 consecutive 21-d treatments (a daily s.c. injection of 3-mg GHRH analog or saline) in a 2 (group) x 2 (period) Latin square crossover design. The 5 cows in group A received GHRH analog during period 1 (from d 22 to 42 postpartum) and saline during period 2 (from d 57 to 77 postpartum), and those in group B received saline and GHRH analog during periods 1 and 2, respectively. Mean milk yield decreased in saline treated compared with that during the 1-wk period before treatment 7.4 and 19.1% during periods 1 (group B) and 2 (group A), respectively. Treatment with GHRH analog increased milk yield 17.4% (period 1, group A) and 6.3% (period 2, group B). Treatment with GHRH analog induced higher basal plasma concentrations of growth hormone (GH), insulin-like growth factor-1 (IGF-1), insulin, and glucose compared with saline-treated cows. In glucose challenge, the GHRH analog-treated beef cows had greater insulin secretion than the saline-treated beef cows. In insulin challenge, however, there were no significant differences in the areas surrounded by hypothetical lines of basal glucose concentrations and glucose response curves between GHRH analog- and saline-treated cows. These results demonstrate that GHRH analog treatment facilitates endogenous GH secretion in lactating Japanese Black cows, leading to increases in milk yield and plasma concentrations of IGF-1, insulin, and glucose.

Abstract
In 1999, two viruses were isolated from blood samples of sentinel cattle in the Western part of Japan. The physiochemical and morphological properties of these viruses indicated that they belonged to the family Bunyaviridae. Sequence analysis of the S segment indicates that the two viruses are closely related to Sathuperi virus (SATV). The N-terminal 168 amino acid of the G2 protein of the M segment was highly homologous with that of SATV (98.2%). Given these results, we conclude that the newly isolated viruses are closest to SATV, which was initially isolated in India and Nigeria over 30 years ago.

Abstract
BACKGROUND With the technical advances of recent years, the number of operative manipulations in the abdominal cavity by laparoscopic surgery is now considered to be the same as that using classical open surgery. The question has been raised whether laparoscopic colorectal surgery with lymphadenectomy improves the recovery compared to open surgery. METHODS We compared patients' physical activity for 7 days postoperatively as measured with an accelerometer between laparoscopic-assisted colorectal resection (LAC, n = 32) and classical open colorectal surgery (OC, n = 30). RESULTS Physical activity expressed as cumulative acceleration was significantly higher in the LAC than in the OC group on each postoperative day. The recovery time, defined as the day on which the cumulative acceleration recovered to 90% of the preoperative level, was significantly shorter (p < 0.05) in the LAC (3.4 +/- 1.2 days) than in the OC group (6.8 +/- 1.7 days). CONCLUSION Our results showed that the duration of convalescence with LAC was significantly shorter than that with the OC procedure. Laparoscopic colorectal surgery appears to allow an earlier recovery after the operation than the classical open procedure, and it is less invasive as assessed by convalescence.

Abstract
With the advent of advanced thoracoscopic techniques, new applications have been expanding their
roles in thoracic surgery. The aim of this paper is to introduce our new thoracoscopic approach in
performing parasternal lymph node dissection of advanced breast cancer for its staging. This technique
does not need the removal of any costal cartilage which is usually done in the conventional classical
technique after radical mastectomy. Thoracoscopic procedure, in which wide and complete parasternal
lymph node dissection is done, is minimally invasive and easy to perform. Therefore, the thoracoscopic technique
may be a suitable alternative to the conventional approach in the future.

Abstract
In the present study, a modified application of the surgical instrument with double balloon is described in
the ovarian cystectomy procedure. This technique has been proved effective and safe especially in removing
chocolate-like cystoma. This new instrument, which we originally designed, has two balloons at the
tip of the catheter. After a cyst is punctured, the inner and outer balloons are inflated to fix the cyst well.
After fixing the cyst with two balloons, the internal needle of the instrument can be removed. This catheter,
named the SAND balloon catheter, is advantageous in laparoscopic ovarian cystectomy.

Abstract
The viruses were isolated from the blood of sentinel cattle and Culicoides biting midges in the Kyushu district, southwestern Japan, in 1999 and identified by neutralization tests as Peaton (PEA) viruses. Before this study, PEA virus had been isolated in Australia only. The nucleotide identity of the nucleocapsid (N) protein encoded by the S segment ranged from 91.1 to 91.6% between the Australian and Japanese strains. A phylogenetic analysis of the N protein sequence revealed that the PEA virus strains are closely related to Aino (AIN) virus and suggested reassortment events for PEA and AIN viruses.

Abstract
BACKGROUND This study of patients with Helicobacter pylori infection and low-grade MALT lymphoma aimed to investigate: 1) the effect of H. pylori eradication therapy on the serum gastrin level, 2) whether changes of the serum gastrin level after therapy could predict the prognosis of patients with this tumour, and 3) the relationship between the gastric H. pylori load, the serum gastrin level and the status of MALT lymphoma. METHODS Thirteen patients with documented low-grade MALT lymphoma and H. pylori infection were enrolled and received H. pylori eradication therapy as the sole initial treatment. The presence of H. pylori, the serum gastrin level, the endoscopic findings, the pathologic features of the biopsies and resected specimens, and the endoscopic ultrasonography findings were evaluated before and after therapy. Follow-up was carried out every 3-6 months. RESULTS H. pylori eradication was eventually achieved in all 13 patients. The pretreatment fasting serum gastrin level decreased from 177.1 +/- 107.4 pg/ml to 129.2 +/- 78.1, 96.4 +/- 66.6 and 80.1 +/- 42.7 pg/ml after 0-3, 3-6 and 6-9 months, respectively (all P < 0.05). Successful eradication of H. pylori was followed by a decrease of the fasting serum gastrin level and complete regression of initial low-grade MALT lymphoma was observed in all patients. However, two patients subsequently developed recurrent high-grade MALT lymphoma or high-grade lymphoma. In one of them, the serum gastrin level rose again above the pretreatment value. In the other, however, the fasting gastrin level fell throughout the study period. The median fasting serum gastrin level before H. pylori eradication therapy was higher in the patients with tumours of the gastric body (203.4 +/- 108.9 pg/ml) than in those with tumours of the antrum and angulus (89.3 +/- 28.0 pg/ml) (P = 0.06). CONCLUSIONS Hypergastrinaemia may be associated with an increased risk of gastric MALT lymphoma.

Abstract
The normal kinetics of ribosomal S6 kinase (RSK) during the meiotic maturation of porcine oocytes were examined. The phosphorylation states of RSK and extracellular signal-regulated kinase (ERK), major mitogen-activated protein (MAP) kinases in maturating porcine oocytes, were detected by Western blotting analysis. The S6 protein kinase activity was assayed using a specific substrate peptide which contained the major phosphorylation sites of S6 kinase. Full phosphorylation of RSK was correlated with ERK phosphorylation and was observed before germinal vesicle breakdown. S6 kinase activity was low in both freshly isolated and 20 h cultured oocytes. S6 kinase activity was significantly elevated in matured oocytes to a level about 6 times higher than that in freshly isolated oocytes. Furthermore, full phosphorylation of RSK was inhibited when oocytes were treated with U0126, a specific MAP kinase kinase inhibitor, in dose-dependent manner, indicating that RSK is one of the substrates of MAP kinase. These results suggest that the activation of RSK is involved in the regulation of meiotic maturation of porcine oocytes.

Abstract
The present study evaluates juvenile stroke-prone spontaneously hypertensive rats (SHRSP) as an animal model of a developmental disorder, which is diagnosed according to hyperactivity-impulsivity and/or inattention. To characterize behavioural alterations, we studied motor activity, as well as emotional and cognitive behaviours in juvenile SHRSP, with and without methylphenidate, a psychostimulant. Ambulatory and rearing activities in the open-field environment were significantly higher in SHRSP than in Wistar-Kyoto rats (WKY). In the elevated plus maze task, the entries into open arms, as an index of impulsivity, were significantly increased in SHRSP. In the Y-maze task, spontaneous alternation behaviour, as an index of attention, was significantly lowered in the male SHRSP, but not in the female SHRSP, indicating that spontaneous alternation deficit is gender specific. Methylphenidate (0.01-1 mg/kg, i.p.) significantly attenuated locomotor hyperactivity at low doses and dose-dependently improved the spontaneous alternation deficit in SHRSP. Our findings reveal that juvenile SHRSP manifest problematic behaviours resembling a developmental disorder, attention-deficit/hyperactivity disorder (ADHD), namely hyperactivity-impulsivity and/or inattention. Methylphenidate alleviated the behavioural symptoms of hyperactivity and inattention. We propose that juvenile SHRSP are an appropriate animal model of a developmental disorder resembling ADHD, from behavioural and pharmacological perspectives.

Abstract
We investigated dynamic cerebral autoregulation during N2O-O2/fentanyl anesthesia (baseline) plus 1.0 and 2.0 minimum alveolar anesthetic concentrations (MAC) of sevoflurane or isoflurane anesthesia in 14 patients undergoing non-neurosurgical operation. Cerebral blood flow velocity in the right middle cerebral artery (Vmca) was measured continuously using transcranial Doppler ultrasonography. At normocapnia, dynamic cerebral autoregulation was tested by transient hyperemic response (a response of Vmca after a brief compression of the ipsilateral common carotid artery). For quantitative comparisons, ratio of systolic Vmca before, to immediately after compression (THRR) was calculated. Values of THRR were 1.14 +/- 0.03 (mean +/- SD), 1.15 +/- 0.04, and 1.12 +/- 0.03 during baseline, 1.0, and 2.0 MAC sevoflurane anesthesia, respectively. THRR was not significantly different among the 3 conditions. In contrast, THRR values were 1.17 +/- 0.03, 1.07 +/- 0.02, and 1.01 +/- 0.01 during baseline, 1.0, and 2.0 MAC isoflurane anesthesia, respectively. THRR was significantly attenuated in a dose dependent manner during isoflurane anesthesia. These results indicate that dynamic cerebral autoregulation is preserved during 2.0 MAC sevoflurane anesthesia, but not during 1.0 MAC isoflurane anesthesia.

Abstract
We investigated the incidence of pulmonary embolism after total hip or knee arthroplasty. Arterial pO2 while the patient was breathing room air was measured at pre-operative day and 5 post-operative day using a Blood Gas Analyzer. Selection of patients for perfusion/ventilation scan during this study was dependent on the results of arterial blood gas determination that was more than 10 mmHg depression Of arterial pO2 level after surgery. More than depression of that was occurred in 11 patients (17.7%). Eight of them (72.7%) detected abnormalities (V/Q mismatch) in perfusion/ventilation scan, and we diagnosed them PE. More than 70% of PE was detected by only estimating the pre and post-operative arterial pO2. It was concluded that the estimation of arterial pO2 (pre and post-operation) was useful for the detection of PE, and combining estimation of arterial pO2 with the clinical feature evaluation method, low-invasive diagnosis and rapid treatment should be possible.

Abstract
To investigate whether postischemic cerebral dysfunction occurs via the interleukin-1 beta/nitric oxide (IL-1beta/NO) pathway, we examined the effects of an IL-1beta antagonist on long-term potentiation (LTP) impairment and excessive NO production in the rat hippocampus after 10-min global ischemia. Intracerebroventricilar administration of the IL-1beta antagonist attenuated NO production and rescued LTP impairment in the perforant path-dentate gyrus synapses, observed 1 day and 4 days after ischemic insult, respectively. There was an inverse relationship between LTP in the dentate gyrus synapses and hippocampal NO production. Centrally applied IL-1beta mimicked the consequences of transient ischemia in LTP formation and hippocampal NO production in non-ischemic rats. These findings indicate that the IL-1beta/NO pathway is involved in the hippocampal LTP impairment observed in the postischemic brain.

Abstract
We investigated dynamic cerebral autoregulation in 24 normocapnic adult patients during propofol and fentanyl anaesthesia. Hypotension was induced, to a mean arterial pressure (MAP) of 60-65 mmHg, using nitroglycerin or prostaglandin E1. Time-averaged mean cerebral blood flow velocity in the right middle cerebral artery was measured continuously using transcranial Doppler sonography. Dynamic autoregulatory response was activated by a sudden decrease in MAP following release of bilateral thigh cuffs (thigh cuff test) and evaluated as a dynamic rate of autoregulation (dRoR in % x s(-1)). The cuff test was repeated to obtain two values of dRoR during baseline and during induced hypotension; the data were then averaged. The mean value of dRoR during baseline and during induced hypotension was 14.2 (2.9) and 14.2 (1.6) % x s(-1), respectively, in the nitroglycerin group, and 14.6 (2.6) and 14.4 (2.4) % x s(-1), in the prostaglandin E1 group. We were unable to demonstrate significant between- or within-group differences in dRoR. Thus, we conclude that nitroglycerin and prostaglandin E1 do not attenuate dynamic cerebral autoregulation.

Abstract
Naked plasmid DNA (pDNA) injection could become an alternative procedure to viral and nonviral gene delivery systems. We have previously shown that Epstein-Barr virus (EBV)-based plasmid vectors containing the EBV nuclear antigen 1 (EBNA1) gene and the oriP sequence enable quite high and long-lasting expression in various in vitro and in vivo transfection systems. The EBV-based plasmids were intravenously injected into mice via their tail vein under high pressure. A large amount of the marker gene product was expressed in the liver; as much as 320 microg of luciferase was demonstrated per gram of liver at 8 to 24 h after a single injection with 10 microg of DNA. More than 70% of liver cells stained with X-gal when beta-gal gene was transferred. The expression level was significantly higher than that obtained by conventional pDNA lacking the EBNA1 gene and oriP. On day 35 after the transfection, the expression from the EBV-based plasmid was approximately 100-fold stronger than the conventional pDNA gene expression. Both the EBNA1 gene and oriP are a prerequisite for the augmentation of the transfection efficiency. These results suggest that the intravascular transfection with naked EBV-based plasmid may provide a quite efficient, simple and convenient means to transduce therapeutic genes in vivo into the liver.

Abstract
We examined 17 total hip arthroplasty patients in order to develop a method for the predictive diagnosis of pulmonary embolism (PE) after joint arthroplasty. Scintigraphy revealed the presence of PE in 4 patients. Prothrombin time (PT), activated partial thromboplastin time (aPTT), antithrombin III (ATIII), and thrombin-AT III complex (TAT) did not show significant differences between patients with and without PE. D-dimer 7 days after surgery showed significant differences between patients with and without PE. Fibrin monomer (FM) increased sharply after surgery, and it was significantly different between the patients with and without PE immediately after surgery and 2 days after surgery. Our findings suggest the importance of FM in the predictive diagnosis of pulmonary embolism after total hip arthroplasty, and 40 microg/ml or higher levels with our measurement method could represent a high-risk condition.

Abstract
The mitogen-activated protein kinase (MAPK) cascade is one of the most important signal transduction pathways that regulate the cell cycle in somatic cells. The present study examined the phosphorylation states of components in the MAPK cascade, Raf-1, MEK-1, and extracellular signal regulated kinases (ERKs), which are activated by mitogens, throughout early mouse embryo development and in cultured somatic cells generally. In somatic cells, Raf-1 and MEK-1 were phosphorylated at M-phase and dephosphorylated during interphase. ERKs were not phosphorylated at any stage during the cell cycle. These results were similar to previous findings for the first and second cell cycles of early mouse embryos. In contrast, after the four-cell stage, not only ERKs, but also Raf-1 and MEK-1, were not phosphorylated at any stage during the cell cycle in mouse early embryos. These results suggest that the MAPK cascade in mouse embryos is regulated by the same mechanism as in somatic cells before the two-cell stage, and that regulation is changed to an embryo-specific mechanism after the four-cell stage.

Abstract
Vascular complications arising from multiple environmental and genetic factors are responsible for many of the disabilities and short life expectancy associated with diabetes mellitus. Here we provide the first direct in vivo evidence that interactions between advanced glycation end products (AGEs; nonenzymatically glycosylated protein derivatives formed during prolonged hyperglycemic exposure) and their receptor, RAGE, lead to diabetic vascular derangement. We created transgenic mice that overexpress human RAGE in vascular cells and crossbred them with another transgenic line that develops insulin-dependent diabetes shortly after birth. The resultant double transgenic mice exhibited increased hemoglobin A(1c) and serum AGE levels, as did the diabetic controls. The double transgenic mice demonstrated enlargement of the kidney, glomerular hypertrophy, increased albuminuria, mesangial expansion, advanced glomerulosclerosis, and increased serum creatinine compared with diabetic littermates lacking the RAGE transgene. To our knowledge, the development of this double transgenic mouse provides the first animal model that exhibits the renal changes seen in humans. Furthermore, the phenotypes of advanced diabetic nephropathy were prevented by administering an AGE inhibitor, (+/-)-2-isopropylidenehydrazono-4-oxo-thiazolidin-5-ylacetanilide (OPB-9195), thus establishing the AGE-RAGE system as a promising target for overcoming this aspect of diabetic pathogenesis.
