Abstract
Biohybrid odorant sensors (BOSs) composed of biological materials and artificial detectors have recently attracted much attention due to their high degree of sensitivity and selectivity. Although portability is crucial for the practical use of BOSs on site, the currently used artificial detectors for biological signals are unportable. In this study, we propose a portable cell-based odorant sensor, which uses cell-laden collagen micropillars to compensate the low optical abilities of portable artificial detectors. The micropillars were composed of HEK293T cells expressing olfactory receptors, which emit a fluorescence signal based on the extent of odorant stimulation using a calcium fluorescent indicator. By stacking cells vertically in the micropillars, we achieved different levels of amplification of the fluorescence signals by varying the height of the micropillars. As a working demonstration of the portable BOS, we successfully detected different concentrations of odorants using an inexpensive web camera. The BOS was also able to distinguish the slight differences between an agonist and an antagonist. We believe that the portability of our BOS would facilitate its applications in point-of-care testing and on-site detection of hazardous materials.

Abstract
Men’s sexual health can have significant effects on a man’s self-esteem, sexual relationship and male reproductive functions. Although commercially available drugs (e.g., VIAGRA and CIALIS) show effective treatment of erectile dysfunction (ED), patients with severe ED fail to respond to these medicines. Topical nitric-oxide (NO) delivery to penis can be a painless, alternative solution with severe ED because NO triggers erection and diffuses to the trabecular arteries and smooth muscles in the penis. We here develop water-in-oil (W/O) nanoemulsions (NEs) that contain NO and can directly spread on the penis. We optimize NE formation conditions including hydrophilic-lipophilic balance (HLB) and ratio of oil, water and surfactants. Then, by spreading NEs on penis skin of intact middle aged dogs, we verify medication effects and safety of the NEs in vivo. The water-in-oil NEs can be a promising non-invasive medication for ED patients with low response to a phosphodiesterase type 5 (PDE5) inhibitor, thus increasing quality of life in the aging society.

Abstract
A collagen sheet with highly aligned collagen fibers is fabricated by continuous cyclic stretch. The rearrangement of the collagen fibers depends on the different process parameters of the cyclic stretch, including magnitude, frequency, and period of stretch. The collagen fibers are aligned perpendicularly to the direction of the stretch. Corneal stromal cells and smooth muscle cells cultivated on the highly aligned collagen sheet show alignment along the collagen fibers without the stretch during culture. Thus, the sheet can be a suitable scaffold for use in regenerative medicine.

Abstract
OBJECTIVE The current study compared canine corneal epithelial cell sheets cultivated from limbal stem cells on amniotic membrane, atelocollagen gel, and temperature-responsive culture dish. PROCEDURES We collected limbal epithelial cells from the intact eyes of beagles and cultivated the cells on denuded canine amniotic membranes, temperature-responsive cell culture labware, and collagen gel with 3T3 feeder cells. Immunofluorescence staining for Ki-67 was used to analyze the capacity of cell proliferation in the sheets. Immunofluorescence staining was also performed for the corneal epithelium-specific marker cytokeratin 3 and putative stem cell markers ABCG2 and p63. Reverse-transcription polymerase chain reaction (RT-PCR) was performed to detect ABCG2 and p63. RESULTS The growth rates of the cultivated cells, or the times it took them to reach confluency, were different for the three scaffolds. The cultivated sheet on the temperature-responsive dish consisted of 2-3 layers, while those on the collagen gel and on the amniotic membrane consisted of 5-8 layers. The basal layer cells grown on all three scaffolds expressed putative stem cell markers. In real-time RT-PCR analysis, the highest level of p63 was observed in the sheets grown on collagen gel. CONCLUSIONS In this study, the cells cultured on the collagen gel demonstrated a capacity for cell proliferation, and the expressions of stem cells in the sheets suggested that collagen gel is the most suitable carrier for clinical use.

Abstract
Stem cell transplantation is one of the most promising yet enigmatic treatments for spinal cord injury (SCI), a common problem in dogs. As pre-differentiated mesenchymal stem cells (MSCs) can be expanded and differentiated into neurospheres in vitro, before being transplanted back, they may prove to be more beneficial for treating SCI. Therefore, we compared the endogenous differentiation potential, including the neuronal cell differentiation, of neurospheres from canine bone marrow MSCs (cBMMSCs) with that of the adipose tissue-derived MSCs (cADMSCs). Nestin-positive neurospheres were generated from MSCs derived from the bone marrow and adipose tissue. Neuronal cells were differentiated from the neurospheres derived from both these tissues. Gene expression analysis revealed that Nestin, βIII-tubulin, NCAM, OCT4 and SOX2 were expressed in MSCs and the corresponding neurospheres. Notably, cBMMSC-derived neuronal cells expressed higher levels of βIII-tubulin. The mRNA expressions of NANOG, Nestin, OCT4 and SOX2 were upregulated in neurospheres derived from both. Immunofluorescence analysis detected the expression of neuronal markers, namely, βIII-tubulin, GFAP, S100, NF200 and MAP2, in differentiated neuron-like cells. Our findings highlight that both cBMMSCs and cADMSCs could be differentiated into neurospheres and neuron-like cells, and therefore, these cells are suitable candidates for cell transplantation. Further, cADMSCs form a more suitable cell source, as larger number of cells could be harvested from cADMSC-derived neurospheres. Future studies employing in vivo transplantation models to investigate the effectiveness of MSCs for treating SCI are warranted.

Abstract
e22169 Background: Topoisomerase IIα protein(topo II) is the molecular target of topo II inhibitors such as anthracyclines and Microtubule-Associated Protein(MAP)-tau protein is associated with taxane sensitivity. Anthracyclins and taxanes are major cytotoxic agents of breast cancer in the adjuvant setting. The aim of this study was to evaluate the predictive and prognostic functions of MAP-tau and topo II in early breast cancers. Methods: Representative breast tumor sections were constructed from paraffin embedded specimens from 78 node positive breast cancer patients. MAP-tau and topo II protein were assessed by immunochemistry using antibody clone 4F1(Affinity BioReagents,USA) and clone Ki-S1 antibody(Dakocytomation,USA). MAP-tau staining of tumor cells was semiquantatively scored as 0, 1+, 2+, 3+ and cases with 0 or 1+ staining intensity were considered MAP-tau negative. Topo II protein over- expression was defined as the detection of nuclear staining in more than median value of evaluated cells. Results: Thirty- four cases (43.6%) of 78 samples showed topo II overexpression and 35 cases(44.9%) showed MAP-tau overexpression in node positive breast cancers. HER2 overexpression was noted in 28 samples (35.9%) and 56 cases (71.8%) were compatible with the luminal type. In 43 patients (55.1%), anthracyclin and taxane were used as adjuvant therapy and in this group, both MAP-tau and topo II overexpression showed lower disease-free survival (DFS) than the others, but statistically not significant. In luminal type, MAP-tau overexpression was poor prognostic factor on DFS in Cox regression.(HR 5.644, 95% CI 1.14–28.07, p=0.034) Conclusions: Topo II overexpression and MAP-tau overexpression in node positive breast cancers were not significant predictive factors for anthracyclin and taxane therapies. As several investigators reported, MAP-tau is associated endocrine therapy sensitivity in patients without chemotherapy, but higher MAP-tau in luminal type was a strong poor prognostic factor in patients who were given chemotherapy and hormonal therapy. No significant financial relationships to disclose.

16053 Background: Little is known about the pathogenesis, risk factors, optimal therapy or outcomes of endometrial stromal sarcoma (ESS). The aim of this study is to evaluate the behavior of ESS in relation to its clinical and pathogenic features and to find the better treatment strategy. Methods: A retrospective analysis was performed of 28 patients with histologically proven ESS treated at our institution between 1987 and 2006. Results: The median follow-up time was 54.7±63.1 months and 5-year survival rate was 82.0%. 16 (57.1%) patients were referred to our institution from private clinics for further treatment of the ESS. They were previously undergone either hysterectomy, myomectomy, or hysteroscopy for presumed benign gynecological conditions. 22 patients (81.5%) showed low grade and 5 patients (18.5%) showed high grade disease. A univariate analysis revealed that histologic grade according to mitotic count is associated with longer survival (p=0.004). However, among those with low grade tumor, 5/20 patients (25%) had recurrence and 2/21 (9.5%) had distant metastasis during the follow-up period. Except for 2 cases, 26 patients with ESS had hysterectomy for their primary treatment. Adjuvant treatment after surgery was performed in 14/26 cases (53.8%). Hormone therapy by progesterone, chemotherapy and/or radiotherapy individually did not influence the overall survival of the patients. However, postoperative adjuvant therapy group regardless of the treatment modality was associated with relatively increased overall survival when compared to the surgery only group (p=0.054). Conclusions: Differential diagnosis of ESS from other benign gynecologic diseases before surgery is a difficult problem. Furthermore, it is advised that postoperative adjuvant therapy should be performed after hysterectomy to prevent recurrence or distant metastasis. No significant financial relationships to disclose.

Abstract
19639 Background: Multiple primary cancers are defined as two or more abnormal growths of tissue occurring simultaneously or abnormal growths of tissues that follow a previous neoplasm but are not metastases of the latter in the same individual. The primary objective of this study was to determine the occurrence, clinical characteristics and prognosis of multiple primary cancers in single institution, respectively. Methods: Between January 1995 and June 2006, patients with multiple primary cancers were selected from a review of patients who had been treated and followed-up in our Ewha Womans University Hospital. Demographic data were obtained from medical records. Results: Two hundred seven patients were selected and patients with multiple primary cancers constituted 1.95% of all malignancies. Male to female ratio was 1.84. (male 134 vs. female 73 patients) The median age first cancer diagnosis was 67 years old in male, 57 in female. The incidence of synchronous cancers is higher than metachronous. (108 vs. 99) and the median time to additional cancers in metachronous group was 35 months. The most frequent cancers was gastrointestinal cancers in both sex synchronously and metachronously. In male, colorectal cancer followed by gastric cancer methchronously (9.1%), genitourinary cancer with another genitourinary cancer synchronously (12.7%) were frequently observed. In female, breast cancer followed by colorectal cancer metachronously (6.8%), gastric cancer with colorectal cancer (6.9%) were frequently observed. The median survival duration was 14.4 months totally from the index diagnosis and synchronous cancers showed lower survival duration than metachronous cancers. (7.4 vs. 26.1 months, p=0.017) Conclusions: Adequate investigations including G-I tract should focus in the first 3 years after initial diagnosis to detect second primary cancers earlier. No significant financial relationships to disclose.

Abstract
A new car seat design, which allows the back part of the seat (BPS) to lower down while a protruded cushion supports the lumbar spine, was quantitatively tested to determine its effectiveness and potentials in reducing whole-body vibration (WBV) and musculoskeletal disorders in automobile drivers. Nine subjects were tested to drive with the seat in: 1) the conventional seating arrangement (Normal posture); and 2) the new seating design (without BPS (WO-BPS) posture). By reducing contact between the seat and the ischial tuberosities (ITs), the new seating design reduced both contact pressure and amplitude of vibrations transmitted through the body. Root-mean-squared values for acceleration along the z-axis at the lumbar spine and ITs significantly decreased 31.6% (p < 0.01) and 19.8% (p < 0.05), respectively, by using the WO-BPS posture. At the same time, vibration dose values significantly decreased along the z-axis of the lumbar spine and ITs by 43.0% (p < 0.05) and 34.5% (p < 0.01). This reduction in WBV allows more sustained driving than permitted by conventional seating devices, by several hours, before sustaining unacceptable WBV levels. Such seating devices, implemented in large trucks and other high-vibration vehicles, may reduce the risk of WBV-related musculoskeletal disorders among drivers.

Abstract
The selection of chemotherapeutic regimens is challenging for metastatic breast cancer (MBC) patients whose diseases have failed to respond to anthracyline and taxane. Capecitabine has advantages of oral administration and favorable toxicity profiles. This study was conducted to evaluate the efficacy of capecitabine and to identify the subgroup of patients who would potentially have benefit from capecitabine monotherapy in patients with anthracycline- and taxane-pretreated MBC. Female patients with MBC who had been previously treated with anthracycline and taxane received oral capecitabine 2500 mg/m(2) divided in two doses daily for 2 wk with 1-wk rest period. Between September, 1999, and December, 2002, a total of 38 patients were enrolled. Among the 36 evaluable patients, one patient achieved a complete response (CR), 9 patients had partial responses (PRs), and 13 patients had stable diseases (SDs). Response rate was 26% [95% confidence interval (CI), 12-40%] and the tumor control rate (TCR, CR+PR+SD) was 61% (95% CI, 45-77%). The median follow-up duration was 27.8 mo. The median duration of response was 8.9 mo, the median time to progression was 4.6 mo, and the median overall survival was 18.1 mo. The major toxicities were hand-foot syndrome, diarrhea, and emesis. There was no treatment-related death. The predictors of better overall survival were positivity of hormone receptor, disease-free survival longer than 1 yr, non-refractoriness to anthracycline, and fewer number (<or= 3) of involved organs. Capecitabine monotherapy is effective and well tolerated for MBC patients who had previously been treated with anthracycline and taxane. The TCR could predict overall survival as well as the objective response in this study, suggesting a possible role of TCR as a surrogate marker for survival in MBC patients on salvage chemotherapy. The patients who have relatively slow growing tumor and less tumor burden could have benefit from capecitabine monotherapy following anthracycline- and taxane-based chemotherapy.

Abstract
We experienced a 58-year-old Korean man with adult T-cell leukemia/lymphoma with features of histologically anaplastic large cell lymphoma involving the skin and testis. The patient had cutaneous nodules in both extremities and a palpable right testicular mass. Right orchiectomy was performed and specimens of removed testicle and skin nodules showed immunohistologically anaplastic large cell lymphoma with T-cell phenotype, and CD30 antigen was positive. A human T-cell lymphotropic virus type 1 (HTLV-1) antibody titer was over 1 : 256 and integration of HTLV-1 proviral DNA pX gene was identified in the peripheral blood mononuclear cells and lymphoma tissue by polymerase chain reaction. Peripheral blood and bone marrow did not show any evidence of characteristic neoplastic T-cells.
