Abstract
OBJECTIVE To determine how intraoperative microelectrode recordings (MER) and intraoperative lead placement acutely influence tremor, rigidity, and bradykinesia. Secondarily, to evaluate whether the longevity of the MER and lead placement effects were influenced by target location (subthalamic nucleus (STN) or globus pallidus interna (GPi)). BACKGROUND Currently most groups who perform deep brain stimulation (DBS) for Parkinson disease (PD) use MER, as well as macrostimulation (test stimulation), to refine DBS lead position. Following MER and/or test stimulation, however, there may be a resultant "collision/implantation" or "microlesion" effect, thought to result from disruption of cells and/or fibres within the penetrated region. These effects have not been carefully quantified. METHODS 47 consecutive patients with PD undergoing unilateral DBS for PD (STN or GPi DBS) were evaluated. Motor function was measured at six time points with a modified motor Unified Parkinson Disease Rating Scale (UPDRS): (1) preoperatively, (2) immediately after MER, (3) immediately after lead implantation/collision, (4) 4 months following surgery-off medications, on DBS (12 h medication washout), (5) 6 months postoperatively-off medication and off DBS (12 h washout) and (6) 6 months-on medication and off DBS (12 h washout). RESULTS Significant improvements in motor scores (p<0.05) (tremor, rigidity, bradykinesia) were observed as a result of MER and lead placement. The improvements were similar in magnitude to what was observed at 4 and 6 months post-DBS following programming and medication optimisation. When washed out (medications and DBS) for 12 h, UPDRS motor scores were still improved compared with preoperative testing. There was a larger improvement in STN compared with GPi following MER (p<0.05) and a trend for significance following lead placement (p<0.08) but long term outcome was similar. CONCLUSION This study demonstrated significant acute intraoperative penetration effects resulting from MER and lead placement/collision in PD. Clinicians rating patients in the operating suite should be aware of these effects, and should consider pre- and post-lead placement rating scales prior to activating DBS. The collision/implantation effects were greater intraoperatively with STN compared with GPi, and with greater disease duration there was a larger effect.

Abstract
We have measured full momentum images of electrons rescattered from Xe, Kr, and Ar following the liberation of the electrons from these atoms by short, intense laser pulses. At high momenta the spectra show angular structure (diffraction) which is very target dependent and in good agreement with calculated differential cross sections for the scattering of free electrons from the corresponding ionic cores.

Abstract
We have measured two-dimensional photoelectron momentum spectra of Ne, Ar, and Xe generated by 800-nm, 100-fs laser pulses and succeeded in identifying the spectral ridge region (back-rescattered ridges) which marks the location of the returning electrons that have been backscattered at their maximum kinetic energies. We demonstrate that the structural information, in particular the differential elastic scattering cross sections of the target ion by free electrons, can be accurately extracted from the intensity distributions of photoelectrons on the ridges, thus effecting a first step toward laser-induced self-imaging of the target, with unprecedented spatial and temporal resolutions.

Abstract
Sera from 27 children and eight older persons, which had been collected in 1998 and 1999 and showed haemagglutination-inhibition (HI) activity against influenza A/Sydney/5/97 (H3N2) strain, were characterized with a binding assay using chimeric haemagglutinin (HA) proteins between A/Aichi/2/68 (A/AI/68) and A/Sydney/5/97 (A/SD/97) strains. Sera from the young children had a tendency to recognize only the antigenic site B1 of the HA1 region. On the other hand, sera of the older individuals were fully reactive to all antigenic sites of HA1 except antigenic site D. Recent epidemic strains, A/Panama/2007/99 (A/PM/99)-like viruses have differences in amino acids in antigenic sites A, C, and B2 but not B1. However, human antisera obtained even from young children had HI activity to Panama-like viruses. The limited epidemic of A/PM/99-like viruses may have been due to the existence of antibody against B1, which had been produced in response to infection by the A/SD/97-like viruses.

Abstract
We developed an orthodontic appliance completely made of organic polymer. The appliance was used for many years and proved very effective. It was used for the treatment of patients with metal allergy, and as a result, it is believed to be the best choice for treating metal allergies. In this report, we are presenting a surgical case with Class III malocclusion for a patient with metal allergy, and the concept of the appliance is briefly discussed.

Abstract
Anomalous junction of the pancreaticobiliary duct (AJPBD) is a congenital anomaly associated with gallbladder carcinoma. Especially patients with noncystic dilatation and without dilatation of the biliary tract are at risk of gallbladder carcinoma. A 56-year-old woman with advanced gallbladder cancer associated with AJPBD but without dilatation of the biliary tract was treated at our hospital. Although histologically cancer cells remained in the layer of the proprial mucosa, extensive metastases to lymph nodes including the paraaorta and peripancreas were detected. According to the TNM classification this case was of Stage IVB. The cancer consisted of medullary round cells, and was diagnosed as undifferentiated carcinoma. After surgery poor prognosis was expected, but three years have elapsed with no recurrence. The case is of interest because of two points of discrepancy: the primary cancer did not show deep invasion but demonstrated extensive lymph node metastases; the cancer was histologically malignant but prognosis was relatively good.

Abstract
Pressure-induced phase transitions in liquid phosphorus have been studied by constant-pressure first-principles molecular dynamics simulations. By compressing a low-pressure liquid which consists of the tetrahedral P4 molecules, a structural phase transition from the molecular to polymeric liquid (a high-pressure phase) observed in the recent experiment by Katayama et al. [Nature (London) 403, 170 (2000)] was successfully realized. It is found that this transition is caused by a breakup of the tetrahedral molecules with large volume contraction. The same transition is also realized by heating. This indicates that only the polymeric liquid can stably exist at high temperature.

Abstract
Changes in DNA superhelicity during DNA replication are mediated primarily by the activities of DNA helicases and topoisomerases. If these activities are defective, the progression of the replication fork can be hindered or blocked, which can lead to double-strand breaks, elevated recombination in regions of repeated DNA, and genome instability. Hereditary diseases like Werner's and Bloom's Syndromes are caused by defects in DNA helicases, and these diseases are associated with genome instability and carcinogenesis in humans. Here we report a Saccharomyces cerevisiae gene, MGS1 (Maintenance of Genome Stability 1), which encodes a protein belonging to the AAA(+) class of ATPases, and whose central region is similar to Escherichia coli RuvB, a Holliday junction branch migration motor protein. The Mgs1 orthologues are highly conserved in prokaryotes and eukaryotes. The Mgs1 protein possesses DNA-dependent ATPase and single-strand DNA annealing activities. An mgs1 deletion mutant has an elevated rate of mitotic recombination, which causes genome instability. The mgs1 mutation is synergistic with a mutation in top3 (encoding topoisomerase III), and the double mutant exhibits severe growth defects and markedly increased genome instability. In contrast to the mgs1 mutation, a mutation in the sgs1 gene encoding a DNA helicase homologous to the Werner and Bloom helicases suppresses both the growth defect and the increased genome instability of the top3 mutant. Therefore, evolutionarily conserved Mgs1 may play a role together with RecQ family helicases and DNA topoisomerases in maintaining proper DNA topology, which is essential for genome stability.

Abstract
A 45-year-old woman was admitted to our hospital in August, 1999. Laboratory data showed a white blood cell count of 5,050/microliter with 78% abnormal lymphocytes, hemoglobin 6.8 g/dl, platelets 4.8 x 10(4)/microliter, and soluble IL-2 receptor 97,600/ml. The abnormal cells were characterized by a hairy appearance under phase contrast microscopy, and showed strong tartrate-resistant acid phosphatase activity. Immunophenotype analysis revealed that these cells were positive for CD11c, CD19 and CD25, and negative for CD5. Bone marrow biopsy showed diffuse proliferation of hairy cells with moderate myelofibrosis. We diagnosed the patient as having European-American-type hairy cell leukemia. Pentostatin was administered at a dose of 5 mg/m2 weekly. After twelve doses, the peripheral blood data returned to the normal range with no hairy cells in the blood or bone marrow, although slight splenomegaly remained. The patient underwent splenectomy in December of the same year, and we were unable to find any hairy cells by histological and immunohistochemical examination. Although most patients with hairy cell leukemia in Japan have the Japanese variant, and the European-American type is rare, pentostatin is as effective as it is for European and American patients.

Abstract
The Ewing family of tumors (ET) generally contain translocations involving the EWS gene and the FLI or ERG genes. Identification of the translocation confirms the diagnosis of ET. Currently, diagnosis of the translocation is made by several methods. In general, these methods require different primer sets for amplifying different translocations and subsequent efforts to identify the amplified product. The need to employ different sets of primers to amplify different translocation junctions presents some limitations. We have developed a method based on PCR with consensus primers followed by direct automated sequencing of the amplified product. With this method we have correctly determined known as well as unknown ET-associated EWS-FLI and EWS-ERG translocations in appropriate specimens. Use of our consensus primers eliminates the need for separate PCRs to amplify EWS-FLI and EWS-ERG translocation junctions, and because direct sequencing is used for confirming the identity of the amplification product, the accuracy of detection becomes 100%. The method might also accurately diagnose ET-associated translocations other than EWS-FLI and EWS-ERG translocations.

Abstract
Complete hydatidiform mole and coexistent fetus (CMCF) is a rare occurrence and is associated with an increased risk of persistent gestational trophoblastic diseases. The aim of this study was to reveal a potential risk factor and to determine optimum management of CMCF cases. Molar tissues are cytogenetically divided into two types, homozygous and heterozygous. The molar tissue of our case showed a 46, XY heterozygous complete mole. Genomic DNA was analyzed by the polymerase chain reaction using sets of unlabelled forward and Cy-5-labelled reverse primers for DNA marker loci. The patient developed persistent trophoblastic disease (PTD) with lung metastasis. Since 1980 there have been 13 reports (including our case) that cytogenetically revealed CMCF and clarified the clinical outcome. Nine of the 16 CMCF cases before 21 weeks of gestation and seven of the 12 CMCF cases after 22 weeks of gestation developed PTD. The incidence of PTD from CMCF was not related to the gestational age at termination or delivery. There were 10 case reports that analyzed the zygosity of a mole, heterozygous or homozygous. Two of six homozygous and three of four heterozygous moles in CMCF cases developed PTD. A heterozygous mole is thought to be a high risk factor for the incidence of PTD. Cytogenetic study is clinically useful for the optimum management of CMCF cases.

Abstract
Human H3N2 influenza A viruses were known to preferentially bind to sialic acid (SA) in alpha2,6Gal linkage on red blood cells (RBC). However, H3N2 viruses isolated in MDCK cells after 1992 did not agglutinate chicken RBC (CRBC). Experiments with point-mutated hemagglutinin (HA) of A/Aichi/51/92, one of these viruses, revealed that an amino acid change from Glu to Asp at position 190 (E190D) was responsible for the loss of ability to bind to CRBC. A/Aichi/51/92 did not agglutinate CRBC treated with alpha2, 3-sialidase, suggesting that SAalpha2,3Gal on CRBC might not inhibit the binding of the virus to SAalpha2,6Gal on CRBC. However, the virus agglutinated derivatized CRBC resialylated with SAalpha2, 6Galbeta1,4GlcNAc. These findings suggested that the E190D change might have rendered the HA able to distinguish sialyloligosaccharides on the derivatized CRBC containing the SAalpha2,6Galbeta1,4GlcNAc sequence from those on the native CRBC.

Abstract
Caffeine concentration in human sweat was estimated by measuring separately the amounts of water and caffeine. After washing a finger with tap water for 15 s and waiting 2 min for drying, 70 microL aqueous ethanol solution in a small vial (0.6 mL) was used to sample for several minutes. Then 3 microL of the aliquot was used for GC/MS analysis of caffeine. As a first-order relationship between the sweat amount secreted on the left and right hands was obtained (correlation factor 0.848), the amount of sweat secretion during sampling on one hand was estimated by the value obtained on the other hand. This new indirect evaluation was used for the estimation of the amount of sweat secreted during sampling. Typical variations of caffeine concentration in sweat were demonstrated. Thirty minutes after the intake of caffeine, it was secreted in sweat, and the secretion had continued for more than 4 h.
