Abstract
Hemifacial microsomia (HFM) is characterized by uni- or bilateral microtia and hypoplasia of the mandible, orbits, facial nerve, and adjacent soft tissues. Patients with Pruzansky-Kaban type III HFM show the most severe facial deformities and often encounter difficulty obtaining treatment. In recent years, orthognathic surgery for HFM-related deformities has often been performed after the patient has stopped growing. However, few detailed reports have described the difficulties of orthognathic surgery for patients with type III HFM. This report describes the case of a patient with type III HFM who underwent three unilateral mandibular reconstructions while still growing, including autogenous reconstructions and secondary distraction osteogenesis, followed by orthognathic surgery with iliac bone grafting for an interpositional gap between the proximal and distal segments after she had stopped growing to improve facial asymmetry and malocclusion.

Abstract
Morphologically stable scaffold-free elastic cartilage tissue is crucial for treating external ear abnormalities. However, establishing adequate mechanical strength is challenging, owing to the difficulty of achieving chondrogenic differentiation in vitro; thus, cartilage reconstruction is a complex task. Auricular perichondrial chondroprogenitor cells exhibit high proliferation potential and can be obtained with minimal invasion. Therefore, these cells are an ideal resource for elastic cartilage reconstruction. In this study, we aimed to develop a novel in vitro scaffold-free method for elastic cartilage reconstruction, using human auricular perichondrial chondroprogenitor cells. Inducing chondrogenesis by using microscopic spheroids similar to auricular hillocks significantly increased the chondrogenic potential. The size and elasticity of the tissue were maintained after craniofacial transplantation in immunodeficient mice, suggesting that the reconstructed tissue was morphologically stable. Our novel tissue reconstruction method may facilitate the development of future treatments for external ear abnormalities.

Abstract
Cleft palate patients with a short palate are sometimes encountered and it is difficult to achieve effective primary palatoplasty and good speech in these cases. Our purpose was to establish an effective palatoplasty for a cleft palate patient with Randall type III short palate. Buccal musculomucosal flap on the nasal side and skin graft on the oral side were performed, along with double opposing Z-plasty. Speech improved postoperation. This procedure brought the nasopharyngeal area closer to the normal anatomical state. In terms of disadvantages, the procedure is rather complicated and depends on the engraftment rate.

Abstract
BACKGROUND Detailed studies have not been conducted on sound localization and speech perception in noise in patients with unilateral congenital aural atresia (UCAA). AIMS/OBJECTIVES To evaluate the benefits of the use of the Vibrant Soundbridge (VSB) for UCAA by performing audiometric and sound localization tests. MATERIALS AND METHODS Four children with UCAA underwent VSB (VORP 503) implantation from 2018 to 2019. Speech perception tests in noise were conducted using the Japanese monosyllable test. The spatial configuration for speech testing consisted of speech presented from the front and noise presented into the normal ear (S0N90). The sound localization test was conducted using nine loudspeakers equally distributed in a semicircle. RESULTS The children's speech perception in noise 6 months after VSB activation was significantly better than before activation (p < .05). Additionally, the children's sound localization ability after VSB activation was significantly better than before VSB activation. CONCLUSION AND SIGNIFICANCE The benefits of VSB use in children with UCAA were revealed using audiometric and sound localization tests.

Abstract
Background/Introduction
Treatment of bifurcation coronary artery lesions remains a major challenge in interventional cardiology. Side branch (SB) stenoses are frequently observed after stent implantation in bifurcation lesions, although angiographically narrowed SBs may not be functionally significant. Fractional flow reserve (FFR), a pressure-derived index of the hemodynamic significance of a coronary artery stenosis, may be useful in determining whether additional intervention is required in jailed SBs. Angiography and intravascular ultrasound (IVUS) derived parameters have showed poor diagnostic accuracy in predicting the functional significance of jailed SBs.
Purpose
The aim of the present study was to use high resolution optical coherence tomography (OCT) imaging to predict functionally significant SB stenoses after provisional stenting defined as SB FFR ≤0.80.
Methods
Seventy-one patients with 71 calcified bifurcation lesions with angiographically intermediate SB stenoses undergoing provisional stenting were enrolled in the prospective study. OCT pullbacks were performed before and after stent placement, and SB FFR was measured after main vessel stenting. SB ostium area (SBOA) was assessed using three-dimensional OCT cut-plane analysis off-line. In addition, we developed a simplified approach to SB ostium assessment based on SB ostium frame count using two-dimensional OCT pullback not requiring off-line 3D reconstruction. For the analysis, consecutive frames were counted between the most distal and most proximal take-off of the SB frames.
Results
Similar to previous studies, quantitative coronary angiography findings were not associated with the functional significance of SBs after main vessel stenting. In contrast, SBOA assessed by 3D-OCT after provisional stenting strongly correlated with post-procedure SB FFR. The optimal cut-off value for the SBOA area to predict a SB FFR ≤0.80 was 0.76 mm2 (sensitivity 82%, specificity 89% and area under the curve of 0.92 (95% CI: 0.84–0.99). A simplified approach to SB ostium assessment using OCT frame count yielded a sensitivity of 82%, specificity 89% and area under the curve 0.92 (95% CI: 0.84 to 0.99) with a cut-off of 4.5 frames allowing detection of functionally significant SB stenoses during the procedure in real time. Figure 1 shows a receiver-operating characteristic curve for SB FFR ≤0.8 and a representative case with SB FFR = 0.66 after provisional stenting and SB ostium frame count equal 3 (Frame 1 to 3)
Conclusion(s)
Assessment of SB using either 3D OCT off-line reconstruction or a simplified approach based on OCT frame count can detect SB branches with FFR ≤0.80 with high sensitivity and specificity. The developed approaches may represent a useful tool to assess provisional stent outcomes.

Abstract
Abstract
Background
Over the last decade, drug-eluting stents (DES) have undergone substantial modifications with thinner struts and more biocompatible durable polymer (DP) or biodegradable polymer (BP). In DP-based DES, after drug elusion has been completed, DP remnants may trigger of local inflammatory vascular reactions and promote delayed healing, leading to accelerated neoatherosclerosis (NA). Thus, BPs have been developed to reduce the above-mentioned risks. Recently, poor strut coverage and in-stent NA are increasingly recognized the cause of late stent failure, but it is unclear whether BPs can reduce the incidence of NA and the poor stent coverage as compared to DPs.
Objectives
The purpose of this study was to compare the incidence of NA and the stent coverage using optical coherence tomography (OCT) between the DPs and the BPs.
Methods
Between July 2016 and April 2018, 127 consecutive patients with new-generation DES who underwent 8-month follow up OCT imaging were enrolled. Patients were divided into the two groups: DP group who had the new-generation durable polymer everolimus-eluting and zotarolimus-eluting stents and BP group who had the new-generation biodegradable polymer sirolimus-eluting and everolimus-eluting stents. We compared patient characteristics including hypertension, dyslipidemia and diabetes mellitus and 8-month follow up OCT findings including NA, uncovered struts and malapposed struts between the two groups.
Results
The DP group comprised 64 patients (50.4%. The incidence of NA, uncovered struts and malapposed struts were similar between the two groups (DPs vs BPs, 1.56% vs 7.94%, P=0.11; 7.80% vs 5.88%, P=0.16 and 2.76% vs 2.01%, P=0.43, respectively) (table). The other parameters were also similar between the two groups.
Table 1 DP group (n=64) BP group (n=63) P value Hypertension 44 (68.8%) 50 (79.4%) 0.2251 Dyslipidemia 39 (60.9%) 37 (58.7%) 0.8573 Diabetes mellitus 25 (39.1%) 30 (47.6%) 0.3731 8 month OCT follow up findings Neoatherosclerosis 1 (1.6%) 5 (7.9%) 0.1147 Uncovered struts 7.8% (2.8–20.4) 5.9% (0.7–16.7) 0.1616 Malapposed struts 0.2% (0–2.8) 0% (0–2.8) 0.4392
Conclusions
The new-generation DP based-DES may have similar effects on vascular response compared to the new-generation BP-based DES during 8-month follow-up period.

Abstract
Background
High sensitive cardiac troponin I (hs-TnI), subunit of cardiac troponin complex, is a sensitive and specific marker of myocardium injury as troponin T. Several studies showed hs-TnI was associated with worse cardiovascular outcomes but relationship between serum hs-TnI level in patients with atrial fibrillation (AF) after pulmonary vein isolation (PVI) and AF recurrence remains unclear.
Methods
We enrolled 444 consecutive AF patients who underwent PVI from May 2017 to September 2018. We investigated the difference of relationship between serum hs-TnI, inflammation markers at 48 hours after PVI and early or late recurrence of AF (ERAF, <3 months and LRAF, during 1 year after PVI in patients with AF) between radiofrequency ablation (RFA) group and cryoballoon ablation (CBA) group.
Results
RFA and CBA were performed in 328 and 116 patients, respectively. There were no significant differences in patient characteristics between RFA group and CBA group. Serum hs-TnI in RFA group was significantly lower than in CBA group (1.93 ng/ml±3.28 vs 5.08 ng/ml±4.29, p<0.001), while hs-CRP was significantly higher in RFA group than CB group (1.97±2.38 mg/dl vs 1.10±0.84 mg/dl, p<0.001). The incidence of ERAF was similar between the two groups (RFA group: 26.8% and CBA group: 21.6%, p=0.262). There was no significant difference of hs-TnI and hs-CRP between patients with ERAF and without ERAF (table). In 213 patients who were followed during 1 year (PVIs were performed from May 2017 to January 2018, RFA 149 and CBA 64 patients), there was no significant association between hs-TnI, hs-CRP and incidence of LRAF (table).
TnI and CRP between RFA and CBA RFA (n=328) CBA (n=116) P value hs-TnI 1.93±3.28 5.08±4.29 <0.001 hs-CRP 1.97±2.38 1.10±0.84 <0.001 3 months follow-up RFA (n=328) CBA (n=116) ERAF (+) ERAF (−) P value ERAF (+) ERAF (−) P value hs-TnI 1.68±1.90 2.02±3.66 0.410 5.03±3.17 5.10±4.56 0.943 hs-CRP 2.23±2.65 1.88±2.27 0.238 1.01±0.84 1.13±0.85 0.524 1 year follow-up RFA (n=149) CBA (n=64) LRAF (+) LRAF (−) P value LRAF (+) LRAF(−) P value hs-TnI 1.61±1.77 1.87±2.69 0.570 4.71±2.14 5.60±5.69 0.664 hs-CRP 2.18±2.24 1.92±2.24 0.550 1.12±0.64 1.12±0.98 0.991
Conclusion
CBA may cause more myocardial injury than RFA, on the contrary RFA may cause more inflammation than CBA. These markers did not affect ERAF and LRAF after PVI.

Abstract
OBJECTIVE To analyze congenital lateral maxillary growth for patients with bilateral cleft lip and palate (BCLP). DESIGN A retrospective study. SETTING Kanagawa Children's Medical Center. MATERIALS Images from computed tomography (CT) of patients with BCLP and control patients that were previously used for treatment. MAIN OUTCOME MEASURES The following landmarks were used: A, the posterior most point of the piriform aperture; B, the superior most point of the acoustic meatus; C, the point at which line A-B intersects the line drawn perpendicular from line A-B to the maxillary tuberosity; and D, the apical most point of the nasal bone. The following distances were then measured using these landmarks: (1) A-B distance; (2) A-C distance; (3) A-C/A-B; (4) the angle between lines A-B and A-D (∠BAD); and (5) B-D distance. RESULT Mean A-B and A-C distances and A-C/A-B were significantly smaller in the BCLP group than in the control group (P < .01 each). Mean ∠BAD was significantly larger in the BCLP group than in the control group (P < .01). Mean B-D distance did not differ significantly between groups. CONCLUSIONS Our results indicated that the lateral maxillary segments of patients with BCLP were more posterior than those of the control group, and segment length was shorter compared to the control group on 3D-CT analysis. The lateral maxillary segments of patients with BCLP were basically suggested to originally be underdeveloped.

Abstract
Secondary upper limb lymphoedema is usually caused by lymphatic system dysfunction. Diagnosis is primarily based on clinical features. However, there are no distinct diagnostic criteria for lymphoedema. Although conventional lymphoscintigraphy is a useful technique to diagnose the severity of lymphoedema, the resultant data are two-dimensional. In this study, we examined the pathology of lymphoedema using single photon emission computed tomography-computed tomography lymphoscintigraphy (SPECT-CT LSG), a new technique that provides 3-dimensional information on lymph flow. We observed lymph flow pathways in the subcutaneous and muscle layers of the upper limbs. A significant positive correlation was found between the dermal back flow (DBF) type and the visualization of lymph nodes around the clavicle (p = 0.000266), the type of lymph flow pathways and the visualization of lymph nodes around the clavicle (p = 0.00963), and the DBF type and the lymph flow pathway (p = 0.00766). As the severity of lymphoedema increased, the DBF appeared more distally in the upper limb and the flow into the lymph nodes around the clavicle decreased, whereas the lymph flow pathways in the muscle layer became dominant. These findings demonstrate the features of lymphoedema pathology and the functional anatomy and physiology of the lymphatic system without the need for cadaver dissection.

Abstract
Skin barrier function is often deficient in obese individuals, but the underlying molecular mechanisms remain unclear. This study investigated how skin structure and lipid metabolism, factors strongly associated with barrier function, differed among 50 Japanese women of greatly varying body mass index (BMI). Subjects receiving breast reconstruction surgery were chosen for analysis to obtain skin samples from the same site. The subjects were classified into two groups, control (BMI < 25 kg/m2) and obese (25 kg/m2 ≤ BMI < 35 kg/m2), according to standards in Japan. Hematoxylin and eosin staining was used to assess skin thickness, Ki-67 immunostaining to examine keratinocyte proliferation, and real-time polymerase chain reaction to measure skin expression levels of genes associated with lipid metabolism. Total lipids, cholesterol, and fatty acids were also measured from these same skin samples. In the obese group, structural changes included epidermal thickening and an increase in the number of Ki-67-positive (proliferating) cells. Both skin cholesterol and fatty acid levels exhibited an “inverted-U” relationship with BMI, suggesting that there is an optimal BMI for peak lipid content and barrier function. Decreased lipid levels at higher BMI were accompanied by downregulated expression of PPARδ and other genes related to lipid metabolism, including those encoding acetyl-CoA carboxylase and HMG-CoA reductase, the rate-limiting enzymes for fatty acid and cholesterol synthesis, respectively. Thus, elevated BMI may lead to deficient skin barrier function by suppressing local lipid synthesis.

Abstract
Background We present the cases of 2 patients with invasive thyroid cancer, who underwent reconstructive surgery using a deltopectoral flap. Although the overall rate of extrathyroidal extension in patients with thyroid cancer is quite low, skin invasion is the most common pattern observed. Reconstructive surgery, involving local skin flaps, is required in these patients. The deltopectoral flap relies on the blood supply from intercostal perforators of the internal thoracic artery and usually requires skin grafting to the donor site. The internal thoracic artery is rarely sacrificed in these cases, even in an advanced surgery such as in patients with invasive thyroid cancer. Case presentation A 55-year-old man with a distended thyroid gland presented to our hospital. He underwent advanced surgery, including skin excision, because we suspected that his tumor was thyroid cancer. The defect was covered with an ipsilateral deltopectoral flap via transposition of the flap, without skin grafting. In the second case, a 67-year-old woman with thyroid cancer that metastasized to her neck lymph nodes presented to our institution. Although the ipsilateral internal thoracic artery was sacrificed near its origin during tumor resection, the deltopectoral flap was raised in the usual manner without any complications. The skin defect caused by the tumor resection was covered with the flap. The patient had an uneventful clinical course for more than 2 years of follow-up. These 2 cases show the effectiveness of using the deltopectoral flap as a reconstructive option for patients with thyroid cancer who underwent radical surgery, resulting in a skin defect. The first case shows that this flap does not always require skin grafting to the donor site. To our knowledge, the second case may be the first report of a deltopectoral flap that was safely raised and applied with resection of the bifurcation of the ipsilateral internal thoracic artery. Conclusions Although thyroid cancer surgery with surrounding skin excision is a rare procedure, we found that the deltopectoral flap was useful and should be the first choice for patients undergoing reconstructive surgery, whether the bifurcation of the ipsilateral internal thoracic artery is sacrificed.

Abstract
INTRODUCTION When prepping for navigation surgery, a reference frame must be fixed to the patient's head with a Mayfield clamp, bone anchor, headset, or headband. Fixation of the clamp or bone anchor with a screw or head pins is invasive, whereas use of a headband or headset is noninvasive. However, during orbital surgery for blowout fractures or orbital tumors, surgeons or instruments can interfere between the reference frame and the optical tracking navigation system, even if using noninvasive fixation. MATERIALS AND METHODS We used an occlusal splint for noninvasive fixation of a reference frame in orbital navigation surgery to overcome the problems. RESULTS A surgeon could operate without interferences between the reference frame and the optical tracking navigation system during orbital navigation surgery. CONCLUSION We recommend the use of an occlusal splint for noninvasive fixation of a reference frame in orbital navigation surgery.

Abstract
Background The collective cell migration of stratified epithelial cells is considered to be an important phenomenon in wound healing, development, and cancer invasion; however, little is known about the mechanisms involved. Furthermore, whereas Rho family proteins, including RhoA, play important roles in cell migration, the exact role of Rho-associated coiled coil-containing protein kinases (ROCKs) in cell migration is controversial and might be cell-type dependent. Here, we report the development of a novel modified scratch assay that was used to observe the collective cell migration of stratified TE-10 cells derived from a human esophageal cancer specimen. Results Desmosomes were found between the TE-10 cells and microvilli of the surface of the cell sheet. The leading edge of cells in the cell sheet formed a simple layer and moved forward regularly; these rows were followed by the stratified epithelium. ROCK inhibitors and ROCK small interfering RNAs (siRNAs) disturbed not only the collective migration of the leading edge of this cell sheet, but also the stratified layer in the rear. In contrast, RhoA siRNA treatment resulted in more rapid migration of the leading rows and disturbed movement of the stratified portion. Conclusions The data presented in this study suggest that ROCKs play an important role in mediating the collective migration of TE-10 cell sheets. In addition, differences between the effects of siRNAs targeting either RhoA or ROCKs suggested that distinct mechanisms regulate the collective cell migration in the simple epithelium of the wound edge versus the stratified layer of the epithelium.

Abstract
Treatment of fracture of the naso-orbitoethmoid (NOE) complex is difficult. There are not only aesthetic issues but also functional consequences related to the lacrimal system. Because prophylactic lacrimal intubation for such fractures remains controversial, we have assessed the effectiveness of intraoperative lacrimal intubation to prevent epiphora as a result of such injuries. Thirteen patients diagnosed with craniomaxillofacial fractures including fractures of the NOE complex were included in the study; 10 had unilateral fractures and 3 bilateral. Computed tomography (CT) showed all patients had displaced fragments that had the potential to damage the lacrimal duct. In 7 patients the fractures included the canthal region and in 6 they did not. All patients were treated by open reduction and internal fixation under general anaesthesia, followed by intraoperative lacrimal intubation unilaterally or bilaterally as required. Lacrimal intubation with a silicone tube was successful in all 13 patients (16 sides). The tube was removed 2-9 months (mean 3.8) postoperatively and no subsequent epiphora were seen during follow-up (mean (3-29 months) 11.3 months). Lacrimal intubation for at least 2 months may prevent epiphora caused by injury to the nasolacrimal system after fractures of the NOE complex.

Abstract
Background Subperiosteal hematoma of the orbit is one of the rare lesions that cause exophthalmos after craniomaxillofacial trauma. Presently, there is no consensus for how to treat this disease. Although some reports have suggested a conservative type of therapy, others have recommended surgical treatments be done during the early stages. Case presentation This case report provides details on the clinical course of a 9-year-old girl with subperiosteal hematoma of the orbit. In this particular patient, a rare case of ipsilateral subfrontal extradural hematoma was also observed. Due to our performing the surgical intervention during the subacute stage, functional complications as well as cosmetic problems were avoided. Conclusion Our results demonstrate that surgical treatments for subperiosteal hematoma of the orbit should be delayed until it can be confirmed that a patient has no other complications. On the other hand, once it has been confirmed that the patient has no other existing problems, immediate surgical therapy with a small skin incision followed by the setting of a drain is recommended in order to achieve an early resolution and avoid complications.

Abstract
BACKGROUND For patients with senile ptosis, aesthetic blepharoplasty can be combined with ptosis surgery. However, the amount of skin excision necessary in blepharoplasty is not clearly defined by measurements of the upper eyelids. OBJECTIVES The authors preoperatively evaluate the amount of skin to be excised in blepharoplasty. METHODS Fifty patients with bilateral senile ptosis were included in this study. The amount of skin to be excised from the upper eyelids was selected based on preoperative measurements of redundant skin, equivalent to the maximum lid height (MLH) while manually stretching the eyelid upwards minus resting lid height (RLH) with the eyes closed passively. Ptosis surgery (such as plication of the aponeurosis) followed blepharoplasty. RESULTS Preoperatively, mean MLH was 35 mm on the right and 36 mm on the left. Mean RLH was 25 mm bilaterally. The mean amount (height) of excised skin was 10 mm on the right and 11 mm on the left. At six months postoperatively, mean MLH and RLH were 29 and 23 mm on both sides, respectively. Significant differences between pre- and postoperative MLH and RDH were seen on both sides (P<.001). No complications due to overexcision were observed, but revision was performed for two patients with asymmetry of the lid folds and five patients with recurrence of drooping. CONCLUSIONS Preoperative measurements of upper eyelid heights (stretched and at rest) appear useful in determining the amount of skin excision required in blepharoplasty for senile ptosis.

Abstract
Upper limb lymphedema that develops after breast cancer surgery causes physical discomfort and psychological distress, and it can require both conservative and surgical treatment. Lymphaticovenous anastomosis has been reported to be an effective treatment; however the disease severity criteria that define indications for this treatment remain unclear. Here, we examined lymphoscintigraphic findings in 78 patients with secondary upper limb lymphedema and classified them into 5 major types (Type I-V) and 3 subtypes (Subtype E, L, and 0). Results revealed that this classification is related to the clinical stage scale of the International Society of Lymphology. Based on intraoperative examination findings in 20 of the 78 patients, lymphatic pressure is likely to be further elevated in Type II-V cases which are characterized by the presence of dermal back flow. Therefore, lymphaticovenous anastomosis should be considered as a treatment option for lymphedema in Type II-V cases. Furthermore, there are only limited lymph vessel sites usable for lymphaticovenous anastomosis in more severe lymphedema types [Types IV and Type V (which is characterized by dermal backflow only in the hand)]. The findings in Type IV-V cases suggest that therapeutic strategies for severe upper limb lymphedema need further consideration.

Abstract
BACKGROUND Nonenzymatic glycation of neural proteins and their end-products (advanced glycation end-products, AGE) have been implicated in the pathogenesis of diabetic neuropathy. We need a development of effective ant-glycation agents for future clinical use. MATERIALS AND METHODS We examined the effects of OPB-9195 (OPB), a new inhibitor of glycation, on the peripheral nerve structure and function in diabetic rats. Eight-week-old Wistar rats were made diabetic by streptozotocin (40 mg kg(-1), i.v.) and OPB (60 mg kg(-1) day(-1)) was given by gavage for 24 weeks. Age- and sex-matched normal Wistar rats were used for comparison. RESULTS During the experimental period, OPB treatment did not affect the reduced body weight, elevated levels of blood glucose and glycated haemoglobin in diabetic rats. At the end of the experiment, delayed tibial motor nerve conduction velocity was significantly improved (by 60%) in treated diabetic rats, with reduction of serum AGE levels. Expression of immunoreactive AGE in the sciatic nerve was reduced in treated diabetic rats compared with those in untreated rats. Sciatic nerve (Na+, K+)-ATPase activity was also restored in treated diabetic rats. On the cross-sectioned sciatic nerves, positive cells with oxidative stress-related DNA damage, as expressed by 8-hydroxy-2'-deoxyguanosine, were less in the peripheral nerve of treated diabetic rats compared with those of untreated rats. CONCLUSION The current study suggested that OPB is beneficial for the reduction of serum AGE and the prevention of diabetic neuropathy.

Abstract
An automated analytical method for determination of polychlorinated biphenyls (PCBs) in fish was developed using supercritical fluid extraction (SFE) in combination with an automated sample preparation instrument (Prep) and GC/MS. By incorporating basic alumina with the sample in the extraction process, and optimizing the amount of carbon dioxide used, fish lipid was selectively reduced. The extract was cleaned up on a Florisil cartridge with Prep. The method was evaluated using naturally contaminated tissues and by comparison of automated analytical method results with those obtained by the conventional method. Mean recovery of PCBs from 3 kinds of fish including hairtail, mackerel and yellowtail were 69.8%, 90.2% and 81.1%, respectively. This method is less laborious and requires far less organic solvent than the conventional method, but produced comparable results.

Abstract
The purpose of this study was to clarify the mechanism underlying early enhanced MR images of breast cancer by dynamic MR imaging from the aspect of tumor angiogenesis. The images depicted by dynamic MR imaging of breast cancer were divided into the following two groups: a marginal strong enhancement (MSE) pattern and a variable pattern without marginal strong enhancement (non-MSE). Twenty patients with invasive ductal carcinoma (maximum diameter < 2 cm) were examined by dynamic MR imaging, and the histological materials were submitted to two-dimensional computer image analysis with immunohistochemistry and histochemistry; morphological microvessel characteristics and microvessel density were examined; and the expression of vascular endothelial growth factor (VEGF) was investigated. In the MSE cases, vessel wall irregularity of capillaries and venules in the peripheral area adjacent to the tumor correlated (p < 0.001) with the enhancement pattern, and the total microvessel density (especially of arterioles with a maximum diameter less than 50 microns) of the peripheral area adjacent to the tumor was significantly higher than that of the tumor area. However, in the non-MSE cases, total microvessel density showed no significant difference between the peripheral area adjacent to the tumor and the tumor area, whereas the capillary density of the tumor area was four times greater than that of the peripheral area adjacent to the tumor. The expression of VEGF was strongly positive for the tumor nest adjacent to the capillaries. These results suggest that the enhanced images of the MSE pattern depend on abundant blood supply from arterioles and that the images of the non-MSE pattern might be reflective of angiogenic activity including variable VEGF expression of tumor cells. Thus the mechanism underlying early dynamic MR images of breast cancer was a complex result of tumor angiogenesis and the microcirculatory environment.

Abstract
There has been considerable interest in the relationship between hormone- secreting endocrine cells and their microvessels in human pituitary gland. However, microcirculatory networks have rarely been studied in three dimensions (3D). This study was designed to visualize and to reveal the relationship between hormone-secreting endocrine cells and their microvessel environment in 3D, using rat pituitary glands under various (hyper/hypo) experimental conditions by confocal laser scanning microscopy (CLSM). Female adult Wistar rats were used after bilateral adrenalectomy or ACTH administration for 2 weeks. Clear 3D reconstructed images of ACTH cells, the microvessel network and counterstained nuclei were obtained at a maximal focus depth of 1 mm by CLSM without any background noise. In the hyperfunctional state, slender cytoplasmic processes of hypertrophic stellate ACTH cells frequently extended to the microvessels. In the hypofunctional state, ACTH cells appeared atrophic and round with scanty cytoplasm, and cytoplasmic adhesions to microvessel network patterns were inconspicuous. Therefore, 3D reconstructed imaging by CLSM is a useful technique with which to investigate the microvessel environment of hormone-secreting cells and has the potential to reveal dynamic hormone-secreting pathways.

Abstract
OBJECTIVE To three-dimensionally visualize the microvessel environment of tumor angiogenesis by confocal laser scanning microscopy (CLSM). STUDY DESIGN To reveal underlying mechanisms of tumor angiogenesis, a 7, 12-dimethylbenz(a) anthracene-induced rat cancer model was used. For demonstrating tumor vasculature, fluorescence injection method (FITC-conjugated gelatin solution) was employed. FITC gelatin was injected into the left ventricle of the rat heart. After complete perfusion, the mammary glands were resected, fixed under ice cold conditions and subjected to immunohistochemistry (IHC) for tumor cells. The LSM-410 (Carl Zeiss, Jena, Germany) was employed on thick sections (300-2,000 microns) to elucidate detailed microvessel networks (MVN) and tumor cells. RESULTS Tumor vasculature on thick sections was clearly detected by CLSM at the maximum focus depth of 2,000 microns. Three-dimensional (3-D), reconstructed images of normal mammary glands showed regular and linear MVN. In DMBA-induced mammary cancer, vascular density of MVN was markedly increased and showed an anastomosing, irregular MVN pattern. Furthermore, focal segmentation and tortuous, branching patterns of microvessels were also seen. CONCLUSION Application of the fluorescence injection method and IHC using CLSM was very useful for studying the 3-D relationship between tumor angiogenesis and neoplastic epithelial changes. These results suggest that application of this technique is ideal for studying 3-D imaging of tumor angiogenesis.

Abstract
Spt7p is a new global transcription factor in Saccharomyces cerevisiae(Gansheroff et al., 1995). We report here that the activities of high affinity phosphate transport and acid phosphatase in particular were decreased in a spt7 null mutant. Northern blot experiments revealed that transcription of the PHO84 and PHO5 genes was impaired in this mutant; expression of the PHO regulatory genes, PHO4 and PHO2, was normal. Spt7p is thus linked with expression of several structural genes of the PHO regulon in yeast.

Abstract
An energy-dependent K+/H+ antiport system is found in Enterococcus hirae ATCC 9790 cultured in a standard complex medium (Y. Kakinuma, and K. Igarashi, J. Biol. Chem. 263:14166-14170, 1988). We have now found that the activity of this antiport system was totally missing in cells cultured in a defined medium. In this defined medium, E. hirae did not grow well at pH near 9, but grew normally at pH below 7.5. This antiport system is important at high pH but dispensable at lower pH for ion homeostasis of this bacterium.

Abstract
AIMS/HYPOTHESIS Advanced glycation end products (AGEs) participate in the pathogenesis of diabetic nephropathy. We reported earlier that OPB-9195, a synthetic thiazolidine derivative and novel inhibitor of advanced glycation, prevented progression of diabetic glomerulosclerosis by lowering serum concentrations of advanced glycation end products and reducing their deposition in the glomeruli. Here, we examined their contribution and that of growth factors, such as transforming growth factor-beta (TGF-beta) and vascular endothelial growth factor (VEGF), to the progression of diabetic nephropathy. We also investigated the expression of type IV collagen in the kidneys of Otsuka-Long-Evans-Tokushima-Fatty (OLETF) rats, a Type II (non-insulin-dependent) diabetes mellitus model, after treatment with OPB-9195. METHODS Using northern blots and immunohistochemical techniques, we determined the renal expression of TGF-beta and type IV collagen mRNAs and proteins in OLETF rats. We also examined OPB-9195's effects on renal expression of VEGF mRNA and protein. RESULTS Concomitant increases in TGF-beta and type IV collagen expression were observed at each point in time in OLETF rats not given OPB-9195. In contrast, OPB-9195 treatment greatly suppressed the renal expression of TGF-beta, VEGF and type IV collagen mRNAs and proteins to that seen in non-diabetic rats. CONCLUSION/INTERPRETATION Since OPB-9195, an AGE-inhibitor, prevented the progression of diabetic nephropathy by blocking type IV collagen production and suppressing overproduction of two growth factors, TGF-beta and VEGF, in diabetic rats, this compound warrants further investigation.

Abstract
Saccharomyces cerevisiae became less sensitive to nickel by a defect of the SPT7 gene encoding a transcription factor. Initial rate of nickel uptake by whole cells of a SPT7-negative mutant FY963 was nearly equal to that of the parent strain FY61, and FY963 accumulated nickel about 1.7-fold of the value of FY61 when cultured in medium containing 0.1 mM NiCl2; most of which was sequestered into vacuoles. The pH gradient-driven nickel uptake by vacuolar membrane vesicles was not altered in FY963, but the amount of polyphosphate in vacuoles was highly elevated. Involvement of Spt7p in nickel detoxification through regulation of vacuolar polyphosphate level in S. cerevisiae was discussed.

Abstract
We investigated the correlation between dynamic magnetic resonance imaging (MRI) findings in breast cancer and tumor angiogenesis in a dimethylbenz(a)anthracene(DMBA)-induced rat breast cancer model. In this study, we clearly demonstrated the three-dimensional (3D) architecture of tumor microvessel networks(MN)by confocal laser scanning microscopy (CLSM)and also investigated the hyperpermeability of tumor microvessels. Dynamic MRI findings were closely related to tumor angiogenesis. Three-dimensional reconstructed image analysis by CLSM revealed that the depicted images were dependent on microvessel density as well as microvessel permeability. It should be emphasized that dynamic MRI may have the potential to evaluate the tumor angiogenic activity in human breast carcinoma.

Abstract
Levels of tissue advanced glycation end products (AGEs) that result from nonenzymatic reactions of glucose and proteins are high in both diabetic and aging people. Irreversible AGE formation is based on increases in AGE-derived protein-to-protein cross-linking and is considered to be a factor contributing to the complications of diabetes. A novel inhibitor of advanced glycation, OPB-9195, belongs to a group of thiazolidine derivatives, known as hypoglycemic drugs; however, they do not lower blood glucose levels. We did studies to determine if OPB-9195 would prevent the progression of nephropathy in spontaneous diabetic rats. In vitro inhibitory effects of OPB-9195 on AGE formation and AGE-derived cross-linking were examined by enzyme-linked immunosorbent assay (ELISA) and SDS-PAGE, respectively. Otsuka-Long-Evans-Tokushima-Fatty (OLETF) rats, a model of NIDDM, were used to evaluate the therapeutic effect of OPB-9195. Light microscopic findings by periodic acid-Schiff (PAS) staining, the extent of AGE accumulation detected by immunohistochemical staining in the kidneys, the levels of serum AGEs by AGE-specific ELISA, and urinary albumin excretion were examined. OPB-9195 effectively inhibited both AGE-derived cross-linking and the formation of AGEs, in a dose-dependent manner in vitro. In addition, the administration of OPB-9195 prevented the progression of glomerular sclerosis and AGE deposition in glomeruli. Elevation of circulating AGE levels and urinary albumin excretion were dramatically prevented in rats, even at 56 weeks of age and with persistent hyperglycemia. We concluded that a novel thiazolidine derivative, OPB-9195, prevented the progression of diabetic glomerular sclerosis in OLETF rats by lowering serum levels of AGEs and attenuating AGE deposition in the glomeruli.

Abstract
A series of cephalosporins, 2-isocephems, and 2-oxaisocephems with C-3' catechol-containing (pyridinium-4-thio)methyl groups and 2-isocephems with C-7 catechol related aromatics have been prepared and evaluated for antimicrobial activity. It turns out that these compounds have highly potent activity against Gram-negative bacteria, especially resistant pathogens such as Pseudomonas aeruginosa. The most active compound of the series was (6S,7S)-7-[2-(2-aminothiazol-4-yl)-2-[(Z)-[(1,5-dihydroxy-4-pyr idon-2-yl) methoxy]imino]acetamido]-3-[[[(4-methyl-5-carboxymethyl)thiazol-2- yl] thio]methyl]-8-oxo-1-aza-4-thiabicyclo [4.2.0] oct-2-ene-2-carboxylic acid which exhibited potent in vitro activity against clinically isolated P, aeruginosa and Acinetobacter baumanii which is also resistant to many anti-infectives, and good in vivo efficacy against clinically isolated P aeruginosa.
