Abstract
Study Objective To report the application of the double bipolar technique in a patient with 1b1 cervical cancer who wished to preserve her fertility potential. Design After experiencing 105 cases of laparoscopic and robotic radical trachelectomy with a 5 year survival rate of 98% and the birth of 29 babies from 51 of these patients who attempted pregnancy, we introduced the double bipolar method to overcome technical difficulties of the procedure due to the necessity for precise dissection and reconstruction in the deep pelvis. We will show our operative techniques, such as nerve sparing radical trachelectomy and retroperitoneal lymphadenectomy for early invasive cervical cancer in a bloodless operative field. Setting Urban general hospital. Patients or Participants Robotic radical trachelectomy using the double bipolar method was performed in three patients with 1b1 cervical cancer. Interventions After Robotic radical trachelectomy using monopolar scissors in 30 cases of stage Ib1 cervical cancer, we considered techniques for a more bloodless operative field. The double bipolar method (DBM) was originated by a robotic gastrointestinal surgeon, Prof Ichiro Uyama. Using robotic Maryland forceps as a cutting device allows for pinpoint accuracy that cannot be found in other instruments. It is important for bladder and ureteral dissection and exposure of vessels. Cuts are made at a very limited point by a lightning strike mechanism, meaning there is minimal thermal spread to adjacent organs. Measurements and Main Results Blood loss was 250ml in the cases presented. In surgeries not using the DBM(n=34), the blood loss ranged from 350ml(100-1200ml). While there is no supporting data, the dissection of the ureter was very smooth. Conclusion A bloodless operative field allows for accurate dissection and can prevent intraoperative injuries. The double bipolar method is able to provide precision cutting and limit thermal spread to adjacent tissue, reducing injury and allowing for a clear operative field.

Abstract
Although many reports have demonstrated that ectopic pain develops in the orofacial region following tooth pulp inflammation, which often causes misdiagnosis and inappropriate treatment for patients with pulpitis, the precise mechanism remains unknown. In the present study, we hypothesized that the functional interaction between satellite glial cells and neurons mediated by interleukin 1β (IL-1β) in the trigeminal ganglion (TG) is involved in ectopic orofacial pain associated with tooth pulp inflammation. The digastric muscle electromyogram (D-EMG) activity elicited by capsaicin administration into the maxillary second molar tooth pulp was analyzed to evaluate the noxious reflex and was significantly increased in rats with inflammation of the maxillary first molar (M1) versus rats injected with saline. A significant increase in the expression of connexin43 (Cx43), a gap junction containing protein, was observed in activated satellite glial cells surrounding second molar-innervating neurons in the TG after M1 pulpitis. Daily administration of Gap26, a Cx43 mimetic peptide and inhibitor, in the TG significantly suppressed the enhancement of capsaicin-induced D-EMG activity and the percentage of Fluoro-Gold (FG)-labeled cells encircled by glial fibrillary acid protein-immunoreactive (IR) + Cx43-IR cells after M1 pulp inflammation ( P < 0.01). The percentage of FG-labeled cells encircled by glial fibrillary acid protein-IR + IL-1β-IR cells, IL-1 type I receptor-IR cells labeled with FG, and TRPV1-IR cells labeled with FG significantly increased after M1 pulp inflammation ( P < 0.01). Daily administration of IL-1ra, an IL-1 receptor antagonist, into the TG significantly reduced the enhancement of capsaicin-induced D-EMG activity and the percentage of TRPV1-IR neurons labeled with FG after M1 pulp inflammation ( P < 0.01). The present findings suggest that satellite glial cell is activated in the TG via activated gap junctions composed of Cx43 following tooth pulp inflammation, which leads to the hyperactivation of remote neurons via IL-1β mechanisms and results in ectopic tooth pulp pain in the adjacent tooth.

Abstract
Iitate, a village in Fukushima Prefecture, suffered little damage from the Great East Japan Earthquake that struck on 11 March 2011. However, all village residents were belatedly ordered to evacuate 1 month after the accident at Fukushima Daiichi nuclear power plant. My family and I had to evacuate to the city of Fukushima, located 40 km from our home in Iitate. This came at a time when my husband and I were planning to start research on Natsuhaze (a type of blueberry grown in Japan) after his retirement. There were conflicting reports. On one hand, the media reported that it was not possible to live in Fukushima. The village of Iitate organised a lecture by an expert to assuage the fear of the residents. The evacuation order 1 month after the disaster contradicted what the expert was saying, and appeared to amplify distrust among the residents. I tried to arrive at my own judgement by measuring the ambient radiation dose in and around my house. Participating in the International Commission on Radiological Protection dialogue seminars provided accurate understanding of the situation. Measurement of radiation doses of wild plants that my husband's father had been cultivating for over 30 years has given me many insights, and I had no concerns about returning to Iitate.

Abstract
Although exogenous 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] administered via intravenous, intramuscular, and oral routes has been tested for efficacy in preventing parturient hypocalcemia in dairy cows, there are few reports concerning intravaginal administration. For this study, 1,25(OH)2D3 was administered via the bovine vaginal lumen, and subsequent changes in blood chemistry, including levels of 1,25(OH)2D3 and several minerals, were measured to confirm vaginal absorption. Each of 5 heifers received a single intravaginal dose of 1 microg of 1,25(OH)2D3/kg body weight; a single control heifer received the ethanol carrier alone. In heifers receiving 1,25(OH)2D3, the plasma 1,25(OH)2D3 levels increased markedly from baseline (88.3 +/- 20.3 pg/mL) within 2 h and reached a peak at 6 h after treatment (1967.4 +/- 1139.6 pg/mL). Plasma Ca levels increased from baseline (10.4 +/- 0.4 mg/dL) to a peak of 11.96 +/- 0.7 mg/dL at 24 h. The levels of inorganic phosphate in plasma increased over time from 7.3 +/- 0.5 to 8.1 +/- 0.8 mg/dL by 6 h and were maintained at a plateau level (9.1 +/- 0.7 to 8.6 +/- 0.6 mg/dL) from 24 to 96 h after treatment. Plasma magnesium decreased from a baseline level of 2.1 +/- 0.1 mg/dL to a plateau level of 1.8 +/- 0.1 mg/dL, which was sustained from 24 to 48 h after treatment. The present study provides evidence of the absorption of exogenous 1,25(OH)2D3 from the bovine vaginal wall, as shown by the marked elevation of plasma 1,25(OH)2D3 levels by 2 h after administration, and indicates the possible utility of intravaginal administration of 1,25(OH)2D3 for prophylaxis of hypocalcemia.

Abstract
In order to improve the pharmacological properties of antisense and antigene oligonucleotides, oligodeoxynucleotides conjugated with amino sugars at the 5'-terminus were synthesized by solid phase fragment condensation (SPFC) method. The obtained DNA-sugar conjugates were evaluated in their chemical and biological activities to show that 5'-end modification of oligonucleotides with sugars enhanced the thermal stability of the hybrid duplex with complementary DNA, the resistance against nuclease digestion and the membrane permeability of the conjugates.

Abstract
BACKGROUND Many studies have indicated that individuals with Down's syndrome (DS) show a specific deficit in short-term memory for verbal information. The aim of the present study was to investigate the influence of the length of words on verbal short-term memory in individuals with DS. METHODS Twenty-eight children with DS and 10 control participants matched for memory span were tested on verbal serial recall and speech rate, which are thought to involve rehearsal and output speed. RESULTS Although a significant word-length effect was observed in both groups for the recall of a larger number of items with a shorter spoken duration than for those with a longer spoken duration, the number of correct recalls in the group with DS was reduced compared to the control subjects. The results demonstrating poor short-term memory in children with DS were irrelevant to speech rate. In addition, the proportion of repetition-gained errors in serial recall was higher in children with DS than in control subjects. CONCLUSIONS The present findings suggest that poor access to long-term lexical knowledge, rather than overt articulation speed, constrains verbal short-term memory functions in individuals with DS.

Abstract
Nonketotic hyperglycinemia (NKH) is an inborn error of metabolism caused by deficiency in the glycine cleavage system (GCS); this system consists of four individual constituents, P-, T-, H-, and L-proteins. Several mutations have been identified in P- and T-protein genes, but not in the H-protein gene (GCSH), despite the presence of case reports of H-protein deficiency. To facilitate the mutational and functional analyses of GCSH, we isolated and characterized a human p1-derived artificial chromosome (PAC) clone encoding GCSH. GCSH spanned 13.5kb and consisted of five exons. Using the PAC clone as a probe, we mapped GCSH to chromosome 16q24 by fluorescence in situ hybridization. The transcription initiation site was determined by the oligonucleotide-cap method, and potential binding sites for several transcriptional factors were found in the 5' upstream region. Direct sequencing analysis revealed five single-nucleotide polymorphisms. The expression profiles of P-, T-, and H-protein mRNAs were studied by dot-blot analysis, using total RNA from various human tissues. GCSH was expressed in all 29 tissues examined, while T-protein mRNA was detected in 27 of the 29 tissues. In contrast, the P-protein gene was expressed in a limited number of tissues, such as liver, kidney, brain, pituitary gland, and thyroid gland, suggesting distinct transcriptional regulation of each GCS constituent.

Abstract
This study investigated the changes in emotions and attitudes of diabetic patients as observed in group work sessions linked to an inpatient diabetic educational program. Using content analysis of transcripts from Sessions 1 and 3 of 8 selected groups (40 patients), in Session 1 negative emotions or attitudes such as anxiety, remorse, or self-blame, a lack of understanding of diabetes, along with a willingness to undertake self-care were frequently expressed. In Session 3, more positive emotions and attitudes towards self-care (willingness, specific plans, and resolutions), satisfaction, and relief or hope were frequently expressed. These results suggest that the patients participating in the group work sessions moved toward adaptation to diabetes, although the effects of the group work were not separated from those of the inpatient educational program.

Abstract
BACKGROUND To better understand the mechanisms of glomerular epithelial cell (GEC) injuries in various diseases, we compared GEC excreted during chemotherapy (antineoplastic drugs) and GEC excreted in renal diseases. METHODS For 19 patients undergoing chemotherapy (85 courses), 69 patients with IgA nephropathy and 16 patients with Henoch-Schölein purpura nephritis, the number of excreted GEC and GEC casts were counted by an immunofluorescent study. The morphological features of GEC were also studied in an immunofluorescent study combined with Hoechst stain. RESULTS Glomerular epithelial cells were detected in 78% of the chemotherapy courses and in 94% of the patients with renal diseases. The GEC casts were observed in 2% of chemotherapy courses, while in renal diseases GEC casts were observed in 60% of the patients. Proteinuria (>30 mg/dL) and hematuria were not identified in any of the chemotherapy courses. The morphology and size of GEC were more variable than that in patients with nephropathy. Furthermore, GEC in patients undergoing chemotherapy often showed small nuclei and fragmented nuclei, which were rarely observed in patients with nephropathy. CONCLUSIONS These results showed that the detachment of podocytes was not directly associated with proteinuria or hematuria. The findings also suggest that GEC are damaged via an apoptotic process by chemotherapy. On the contrary, GEC may be detached through a non-apoptotic process in renal diseases.

Abstract
Biliary components are transported by hepatic adenosine triphosphate-binding cassette (ABC) transporters that are located in canalicular membranes. Physiological transporter function is related to membrane fluidity, which is modulated by the phospholipid composition of the lipid bilayer. We hypothesized that cholestasis may alter transporter function by modifying phospholipid species to protect the cell from cholestatic damage. Therefore, we examined the expression of ABC transport proteins and their mRNA levels in canalicular membrane vesicles isolated from rat liver 6 hr or three days after bile duct ligation. Membrane lipid composition and membrane fluidity of both sinusoidal and canalicular membrane vesicles were also examined. By 6 hr after bile duct ligation, we found a clear increase of mdr2 and bsep mRNA. These changes were associated with an increase of mdr-Pgp and with a clear decrease of mrp2 protein, and small decrease of bsep protein. In addition, mdrlb mRNA showed a strong increase by three days after bile duct ligation. Canalicular membrane fluidity decreased in a marked time-dependent manner, whereas sinusoidal membranes showed biphasic changes: increased fluidity at 6 hr and a decrease at three days. These changes were closely related to the changes of membrane lipid constitution; the saturated/unsaturated fatty acid ratio increased for phosphatidylcholine in canalicular membrane and the reverse occurred in sinusoidal membrane, and those for sphingomyelin showed the opposite pattern. We conclude that cholestasis causes modulation of ABC transporters as well as that of the lipid constitution in lipid bilayer. These may confer cytoprotective resistance to hepatocytes against cholestatic stress.

Abstract
The initial presentation of a patient with Wegener's granulomatosis was indistinguishable from that of Henoch-Schönlein purpura. The patient presented with skin purpura and pulmonary hemorrhage followed by purpura in the colon. The diagnosis of this patient at that time was Henoch-Schönlein purpura. With time, massive lesions in the sinus and those with cavities in the lung became apparent, and a specimen obtained from the sinus massive lesion was disclosed to be granulomatous inflammation. Retrospectively, the proteinase 3 antineutrophil cytoplasmic antibody turned out to be strongly positive in her stored serum from the time of the initial presentation.

Abstract
Sulfobromophthalein (BSP) is selectively taken up by the liver and secreted into the bile as unconjugated and conjugated forms. Our previous study demonstrated that unconjugated BSP, but not conjugated BSP, caused the dissociation of biliary lipid secretion from that of bile acids, suggesting that the hepatic BSP conjugation rate partly regulated biliary lipid secretion. To evaluate the mechanisms through which biliary lipid secretion is regulated by exogenous organic anions, we intravenously administered BSP to male Sprague-Dawley rats at various doses either continuously or as a bolus. Then the relationship of the dose of BSP to its conjugation rate, hepatic transit time, and biliary lipid secretion was determined. BSP decreased biliary secretion of cholesterol and phospholipids in a dose-dependent manner without affecting bile acid secretion. In contrast, the proportion of conjugated BSP in bile was associated with the dose. Although the serum clearance of BSP after bolus infusion was constant regardless of the dose administered (50 or 200 nmol/100 g), BSP secretion was delayed with increasing doses: unconjugated BSP was secreted predominantly in the early phase (0-15 min after bolus injection), and conjugated BSP was the predominant form in the late phase (15-30 min). Pretreatment with colchicine reduced the conjugation rate and hepatic transit time of BSP, suggesting that the microtubule-dependent vesicle pathway plays a role in biliary excretion and conjugation of BSP. We conclude that biliary lipid secretion is influenced by organic anions with an affinity for bile acids such as BSP and that this effect is dependent upon the hepatic metabolic rate, i.e., conjugation rate. The hepatic transit time also plays a key role in this process by influencing metabolism.

Abstract
A 54-year-old woman, who had underwent an adjuvant radiotherapy following the modified radical mastectomy in the left primary breast cancer in June 1988. She underwent second surgery and adjuvant radiotherapy (electronic radiotherapy) for recurrent breast cancer in the major pectoral muscle and received chemoimmunotherapy in May 1989. In May 1996 she complained of two ulcers of the chest wall. The ulcer biopsy findings was squamous cell carcinoma, and we diagnosed she fell the radiation-induced skin cancer. She underwent chest wall resection and reconstruction with vertical rectal abdominal musculocutaneous flap (VRAM). However two months later her chest wall resection, she again got the recurrent squamous cell carcinoma in the right axillary lymph nodes and left pleura. The third radiotherapy and the chemotherapy with pepleomycin were uneffective on her recurrent cancer. And she died in March 1997.

Abstract
We observed severe overhydration in an 18-month-old Japanese girl with primary polydipsia. The secretion of antidiuretic hormone (ADH) was decreased, and urinary excretion of aquaporin-2, a vasopressin-sensitive water channel protein, was suppressed under basal conditions, but the response of aquaporin-2 to ADH was essentially preserved. These findings suggest that the water channel itself was intact and that overhydration resulting from polydipsia was responsible for the decreased ADH secretion and suppression of the water channel protein.

Abstract
We devised a simple and effective purification method for the microdetermination of 6,15-diketo-13,14-dihydro-prostaglandin F1alpha (DK), a metabolite of prostacyclin (PGI2). [18O]DK was synthesized from the repeated base-catalyzed hydrolysis of methyl ester derivatives in [18O] water to obtain an internal standard for the gas chromatography/selected ion monitoring (GC/SIM) of DK. The methyl ester-methoxime-tert-butyldimethylsilyl ether derivative was prepared, then gas chromatography/selected ion monitoring was carried out by monitoring the ion at m/z 613.4 for DK and at m/z 617.4 for an internal standard. A good linear response over the range of 10 pg to 10 ng was demonstrated. We detected DK to a level of about 297.8 pg/ml in human plasma. This method can be used to determine DK in biological samples.

Abstract
This is the first report on the molecular basis of human complement C1s deficiency. Two abnormalities in the C1s gene were identified in a Japanese family, including one patient, by using exon-specific PCR, single-strand conformation polymorphism analysis, and nucleotide sequencing. A deletion of 4 bp, TTTG, was identified in exon X when using genomic DNA from the patient, his father, and his paternal grandmother. They were all heterozygous for the mutation. The mutant gene encodes a truncated C1s from the N terminus to the short consensus repeat domain. By further sequencing the PCR products, a nonsense mutation from G to T was identified at codon 608 in exon XII in the patient, his mother, and his sister. They were all heterozygous for the nonsense mutation. The mutant gene encodes a truncated form of C1s that lacks the C-terminal 80 amino acids. These results indicate that the patient was a compound heterozygote with the 4-bp deletion on the paternal allele and the nonsense mutation on the maternal allele. The levels of serum C1s seem to be correlated to the genotypes of the C1s gene in which no C1s was detected in the patient, and one-half of the normal level in the family members who are heterozygous for either mutation. The present study demonstrates that the disease is inherited in an autosomal recessive mode.

Abstract
We present four cases of common bile duct carcinoma in which both angiographic helical CT (angio-HCT) and pancreatoduodenectomy were done in the 3 years since 1995. Angio-HCT was performed with direct infusion of the contrast medium through the gastroduodenal artery inserted on angiography. Angio-HCT displayed the tumors as lower density areas in contrast to the strong enhancement of the circumferential nontumorous areas, including the pancreas and duodenum.

Abstract
This study examined the influence of social support (perception and utilization) on diabetic control. Subjects were 178 patients with diabetes mellitus [insulin dependent diabetes mellitus (IDDM) = 26, non-insulin dependent diabetes mellitus (NIDDM)= 152]. HbA1c values was used as an indicator of diabetic control. Assessment of social support was performed using the Stress and Coping Inventory. HbA1c values were significantly related to the presence or absence of participation in a diabetic education program as well as scores on perception and utilization of social supports. The participation in the diabetic education program was not significantly associated with the two social supports, however, the two social support factors interacted significantly with one another. As for type of DM, these findings were stronger in IDDM patients. These results suggest that, in particular patients with NIDDM, although diabetes education is effective for decreasing HbA1c, a combination of the two social supports also decrease the HbA1c value, independent of diabetic education.
