Abstract
A vital step in the development of heart failure is the transition from compensatory cardiac hypertrophy to decompensated dilated cardiomyopathy (DCM) during cardiac remodeling under mechanical or pathological stress. However, the molecular mechanisms underlying the development of DCM and heart failure remain incompletely understood. In the present study, we investigate whether Gab1, a scaffolding adaptor protein, protects against hemodynamic stress-induced DCM and heat failure. We first observed that the protein levels of Gab1 were markedly reduced in hearts from human patients with DCM and from mice with experimental viral myocarditis in which DCM developed. Next, we generated cardiac-specific Gab1 knockout mice (Gab1-cKO) and found that Gab-cKO mice developed DCM in hemodynamic stress-dependent and age-dependent manners. Under transverse aorta constriction (TAC), Gab1-cKO mice rapidly developed decompensated DCM and heart failure, whereas Gab1 wild-type littermates exhibited adaptive left ventricular hypertrophy without changes in cardiac function. Mechanistically, we showed that Gab1-cKO mouse hearts displayed severe mitochondrial damages and increased cardiomyocyte apoptosis. Loss of cardiac Gab1 in mice impaired Gab1 downstream MAPK signaling pathways in the heart under TAC. Gene profiles further revealed that ablation of Gab1 in heart disrupts the balance of anti- and pro-apoptotic genes in cardiomyocytes. These results demonstrate that cardiomyocyte Gab1 is a critical regulator of the compensatory cardiac response to aging and hemodynamic stress. These findings may provide new mechanistic insights and potential therapeutic target for DCM and heart failure.

Abstract
OBJECTIVE The study was aimed to explore the underlying mechanisms and identify the potential target genes by bioinformatics analysis for non-small-cell lung carcinoma (NSCLC) treatment in non-smoking women. MATERIALS AND METHODS The microarray data of GSE19804 was downloaded from Gene Expression Omnibus (GEO) database. Paired samples (from the same patient) of tumor and normal lung tissues from 60 non-smoking female NSCLC patients were used to identify differentially expressed genes (DEGs). The functional enrichment analysis was performed. Furthermore, the protein-protein interaction (PPI) network of the DEGs was constructed by Cytoscape software. The module analysis was performed. RESULTS Totally, 817 DEGs including 273 up- and 544 down-regulated genes were identified. The up-regulated genes were mainly enriched in extracellular matrix (ECM)-receptor interaction, focal adhesion and cell cycle functions, while down-regulated genes were mainly enriched in the cytokine-cytokine receptor interaction pathway. DEGs including hyaluronan-mediated motility receptor (HMMR), collagen, type I alpha 2 (COL1A2), cyclin A2 (CCNA2), MAD2 mitotic arrest deficient-like 1 (MAD2L1), interleukin 6 (IL6) and interleukin 1, beta (IL1B) were identified in these functions. These genes were hub nodes in PPI networks. Besides, there were 3 up-regulated modules and 1 down-regulated module. The significant pathways were ECM-receptor interaction and focal adhesion in up-regulated modules, while in down-regulated module, the significant pathway was mitogen-activated protein kinase (MAPK) signaling pathway. CONCLUSIONS The ECM-receptor interaction, focal adhesion, cell cycle and cytokine-cytokine receptor interaction functions may be associated with NSCLC development. Genes such as HMMR, COL1A2, CCNA2, MAD2L1, IL6 and IL1B may be potential therapeutic target genes for NSCLC.

Abstract
MicroRNAs (miRNAs) may be important mediators of the profound molecular and cellular
changes that occur after traumatic brain injury (TBI). However, the changes and
possible roles of miRNAs induced by voluntary exercise prior to TBI are still not
known. In this report, the microarray method was used to demonstrate alterations in
miRNA expression levels in the cerebral cortex of TBI mice that were pretrained on a
running wheel (RW). Voluntary RW exercise prior to TBI: i) significantly decreased
the mortality rate and improved the recovery of the righting reflex in TBI mice, and
ii) differentially changed the levels of several miRNAs, upregulating some and
downregulating others. Furthermore, we revealed global upregulation of miR-21,
miR-92a, and miR-874 and downregulation of miR-138, let-7c, and miR-124 expression
among the sham-non-runner, TBI-non-runner, and TBI-runner groups. Quantitative
reverse transcription polymerase chain reaction data (RT-qPCR) indicated good
consistency with the microarray results. Our microarray-based analysis of miRNA
expression in mice cerebral cortex after TBI revealed that some miRNAs such as
miR-21, miR-92a, miR-874, miR-138, let-7c, and miR-124 could be involved in the
prevention and protection afforded by voluntary exercise in a TBI model.

Abstract
BACKGROUND The use of extra-levator abdominoperineal resection (ELAPE) procedure for lower rectal cancer is controversial. It is unclear whether the ELAPE procedure could improve surgical safety and lead to better oncological outcomes. METHODS Sixty-nine lower rectal cancer patients who underwent ELAPE (36 cases) or conventional abdominoperineal resection (APE; 33 cases) between June 2011 and February 2013 were prospectively investigated. Clinicopathological variables including blood loss, intraoperative perforation (IOP) rate, circumferential resection margin (CRM) involvement, lymph node harvest, the postoperative complications, urinary and sexual function, quality of life (QOL), local recurrence rate and survival were recorded and compared. RESULTS Blood loss (P = 0.021), perineal wound complication (P = 0.039), IOP rate (P = 0.028), local recurrence (P = 0.034) were significantly less frequent in the ELAPE group. There was greater CRM involvement in the conventional APE group but no statistical difference between the two groups. Urinary function, sexual function and QOL were not significantly different between the two groups. Overall survival and progression-free survival were not significantly different between two groups, even when survival was analyzed according to TNM stage, T stage, N stage, and with or without neoadjuvant chemoradiotherapy. In patients who underwent ELAPE there was no statistical difference in postoperative complications between younger and elderly patients (age ≥60). CONCLUSIONS ELAPE procedure with definitive anatomic landmarks demonstrated surgical safety and decreased local recurrence for lower rectal cancer patients including the elderly, but there were no survival improvements in compared to conventional APE procedure.

Abstract
The tumor suppressor p53, nuclear factor-κB (NF-κB) and reactive oxygen species (ROS) have crucial roles in tumorigenesis, although the mechanisms of cross talk between these factors remain largely unknown. Here we report that miR-506 upregulation occurs in 83% of lung cancer patients (156 cases), and its expression highly correlates with ROS. Ectopic expression of miR-506 inhibits NF-κB p65 expression, induces ROS accumulation and then activates p53 to suppress lung cancer cell viability, but not in normal cells. Interestingly, p53 promotes miR-506 expression level, indicating that miR-506 mediates cross talk between p53, NF-κB p65 and ROS. Furthermore, we demonstrated that miR-506 mimics inhibited tumorigenesis in vivo, implicating that miR-506 might be a potential therapeutic molecule for selective killing of lung cancer cells.

Abstract
OBJECTIVE To find the novel hypolipidemic agents, the effects of ursolic acid and artesunate on hyperlipidemia and its complications were determined in rabbit fed with Western-type diet. METHODS AND RESULTS New Zealand rabbits fed a Western-type diet developed a hyperlipidemia. Rabbits received ursolic acid (25mg/kg) or artesunate (25mg/kg) alone, or in combination (12.5+12.5mg/kg), to prevent hyperlipidemia. Ursolic acid or artesunate alone significantly decreased the plasma cholesterol and triglyceride in rabbits. Furthermore, they both attenuated liver steatosis and reduced the area of aortic root lesions. The combination of ursolic acid and artesunate was more potent than either agent alone, which indicates a strong synergistic effect. CONCLUSION The hypolipidemic effect of artesunate is firstly reported. Its combination with ursolic acid might have the potential to further develop for the treatment of atherosclerosis.

Abstract
AIMS/HYPOTHESIS The generation of induced pluripotent stem cells (iPSCs) provides a promising possibility for type 1 diabetes therapy. However, the generation of insulin-producing cells from iPSCs and evaluation of their efficacy and safety should be achieved in large animals before clinically applying iPSC-derived cells in humans. Here we try to generate insulin-producing cells from rhesus monkey (RM) iPSCs. METHODS Based on the knowledge of embryonic pancreatic development, we developed a four-stage protocol to generate insulin-producing cells from RM iPSCs. We established a quantitative method using flow cytometry to analyse the differentiation efficiency. In addition, to evaluate the differentiation competence and function of RM iPSC-derived cells, transplantation of stage 3 and 4 cells into immunodeficient mice was performed. RESULTS RM iPSCs were sequentially induced to definitive endoderm (DE), pancreatic progenitors (PP), endocrine precursors (EP) and insulin-producing cells. PDX1(+) PP cells were obtained efficiently from RM iPSCs (over 85% efficiency). The TGF-β inhibitor SB431542 promoted the generation of NGN3(+) EP cells, which can generate insulin-producing cells in vivo upon transplantation. Finally, after this four-stage differentiation in vitro, insulin-producing cells that could secrete insulin in response to glucose stimulation were obtained. When transplanted into mouse models for diabetes, these insulin-producing cells could decrease blood glucose levels in approximately 50% of the mice. CONCLUSIONS/INTERPRETATION We demonstrate for the first time that RM iPSCs can be differentiated into functional insulin-producing cells, which will provide the basis for investigating the efficacy and safety of autologous iPSC-derived insulin-producing cells in a rhesus monkey model for type 1 diabetes therapy.

Abstract
PURPOSE To confirm whether detailed gait analysis can detect gait instability in patients with small vestibular schwannoma (VS) with an apparently normal gait. METHODS Twenty-two patients (7 males, 15 females; 40-64 years old) with small VS and nine healthy age- and weight-matched controls were enrolled. Small VS was defined as the longest diameter less than 20mm from the porus acusticus internus on MRI with no brainstem compression. Each subject was asked to walk straight for a distance of 8m with tactile sensors attached to both feet, and repeat two trials with eyes open and closed. Gait variables of stance, swing, double support, stability, and average length of the trajectories of the center of force (TCOF) during stance were recorded and analyzed. RESULTS No significant differences in the stability of the TCOF were found during gaits with eyes open and closed between the two groups. No obvious changes in gait variables were recognized with eyes open between the two groups. However, under gait with eyes closed, the values of the coefficient of variation (CV) of the gait phase were significantly greater in stance and swing in the VS group than in the normal group. In addition, patients with canal paresis (CP) showed greater CV values in gait phase related parameters than those who without CP during gait with eyes closed. CONCLUSIONS Patients with small VS may have an apparently normal gait, but their vestibular deficit could be detected by proper use of gait analysis, especially with visual deprivation.

Abstract
Cryopreservation of callus of Dioscorea bulbifera by vitrification was optimized. Calli of Dioscorea bulbifera were pretreated in liquid Murashige and Skoog (MS) medium supplemented with 2 mg L(-1) kinetin (KT), 0.5 mg L(-1) NAA, 0.5 mg L(-1) 2,4-D and 0.2 M sucrose for 5 d under continuous light (36 microM m(-2) s(-1)) at 25 + or - 1 degree C. The material was then loaded with 60 percent vitrification solution (PVS2) for 20 min at room temperature and dehydrated with 100 percent PVS2 for 30 min at 0 degree C. After changing the solution with fresh PVS2, the calli were directly immersed in liquid nitrogen and conserved for 1- 360 d. After rapid thawing in a water-bath at 35 degree C, the calli were washed three times with liquid MS medium supplemented with 2 mg L(-1) KT, 0.5 mg L(-1) NAA, 0.5 mg L(-1) 2, 4-D and 1.2 M sucrose and then transferred onto solid MS medium supplemented with KT 2 mg L(-1), NAA 0.5 mg per liter, 0.09 M sucrose and 0.75 percent agar. The cultures were kept in the dark for 2 days prior to exposure to the light (12 h light-dark cycle). The TTC test showed that 80-90 percent of the calli survived this cryoprocedure and there was a 60-70 percent regeneration of plantlets from the calli. The regenerated material did not exhibit any morphological variations.

Abstract
BACKGROUND Second-generation oral H1-antihistamines have become a mainstay of treatment for the symptoms of seasonal allergic rhinitis; however, the effect of olopatadine has not been widely reported to date. OBJECTIVES To evaluate the efficacy of 2 oral H1-antihistamines, olopatadine and fexofenadine, in the treatment of the nasal symptoms of Japanese cedar pollinosis and their possible side effects. METHODS This was a randomized, double-blind, placebo-controlled, crossover study conducted in an environmental exposure unit (EEU). Twenty volunteers suffering from Japanese cedar pollinosis were randomly divided into 3 groups and exposed to cedar pollen in the EEU with oral administration of olopatadine hydrochloride (5 mg), fexofenadine hydrochloride (60 mg), or placebo 1 hour prior to pollen exposure. Nasal symptoms, activity impairment, and subjective sleepiness were self-assessed during the study period. Attention was measured using the digit cancellation test. The trial was repeated after 4 and 7 weeks. RESULTS Compared with placebo, olopatadine significantly improved nasal symptoms and activity impairment during pollen exposure (P < .05). There was no significant relief of nasal discharge or nasal congestion with fexofenadine throughout the 5-hour exposure to cedar pollen. Furthermore, olopatadine significantly reduced nasal congestion during the first 2 hours, as well as sneezing and nasal discharge 4 hours after admission to the EEU compared with fexofenadine (P < .05). There was no significant difference in the effect on subjective sleepiness among the 3 groups, and all 3 agents had little effect on attention. CONCLUSIONS These findings suggest that olopatadine is more effective than placebo and fexofenadine in improving nasal symptoms of Japanese cedar pollinosis.

Abstract
Malignant melanomas are characterized by their high propensity to invade and metastasize, but the molecular mechanisms of these traits have remained elusive. Our DNA microarray analyses of benign nevi and melanoma tissue specimens revealed that the genes encoding extracellular matrix proteins tenascin-C (TN-C), fibronectin (FN), and procollagen-I (PCOL-I) are highly upregulated in invasive and metastatic melanomas. The expression and distribution of these proteins were further studied by immunohistochemistry in benign nevi, radially and vertically growing melanomas, sentinel node micrometastases, and macrometastases. TN-C was increased in all invasive tumours and metastases, especially at invasion fronts, but not in benign nevi or non-invasive melanomas. Significantly, the intensity of TN-C staining correlated with metastasis to sentinel lymph nodes, better than tumour thickness (Breslow). Moreover, TN-C, FN, and PCOL-I appeared to co-localize in the tumours and form tubular meshworks and channels ensheathing the melanoma cells. Our data suggest that melanoma invasion is associated with the formation of special channel-like structures, providing a new concept, structured tumour cell spreading. Altogether, these data provide potential new prognostic markers and therapeutic targets/strategies for preventing melanoma dissemination.

Abstract
Pseudoxanthoma elasticum (PXE) is a hereditary disorder of elastic tissue. The characteristic skin changes are asymptomatic yellow papules around the neck and in body folds giving the skin a characteristic cobblestone appearance. The eyes, cardiovascular and gastrointestinal systems are also commonly involved. In this case-series, we present a family of four children, three of whom demonstrated diverse manifestations of PXE. The first child presented with sudden death at age 3 and showed marked coronary and renal arterial intimal fibrosis with prominent fragmentation of the internal elastic lamina, initially attributed to idiopathic arterial calcification. The second child presented with clinical features and histology of the skin typical of PXE at age 11 and the third child, with abnormal, but non-specific cardiological findings at age 8, which raised the possibility of an early stage of PXE. This report emphasizes the importance of considering pseudoxanthoma elasticum in diverse clinical settings, early diagnosis and appropriate screening for asymptomatic family members.

Abstract
OBJECTIVES To evaluate the long-term impact on physical function of a single course of rituximab in rheumatoid factor, seropositive patients with active rheumatoid arthritis (RA) despite ongoing methotrexate treatment. METHODS A randomized, controlled trial comparing rituximab alone [1,000 mg intravenously (iv) on days 1 and 15, n= 40], or in combination with cyclophosphamide (750 mg iv on days 3 and 7, n= 41) or oral methotrexate (> or =10 mg/week, n= 40) with placebo + methotrexate (> or =10 mg/week, n= 40), resulted in significant reductions in disease activity at weeks 24 and 48. Sustained improvements in physical function and standard effect sizes (SES) for changes in components of ACR and EULAR criteria were evaluated over 2 yrs. RESULTS More patients receiving rituximab + methotrexate completed a 2-yr follow-up without further treatment than those receiving placebo + methotrexate (45% vs 15%, respectively), rituximab alone (10%) or rituximab + cyclophosphamide (22%). This reflected a higher percentage of patients receiving rituximab + methotrexate reporting improvements in Health Assessment Questionnaire Disability Index > or = minimum clinically important difference at 1 and 2 yrs (68% and 30%, respectively) compared with placebo + methotrexate (28% and 15%), rituximab monotherapy (43% and 10%) or rituximab + cyclophosphamide (39% and 12%). SES were high in all rituximab groups and revealed differing patterns of response over time. CONCLUSION A single course of rituximab with continuing methotrexate in patients with active RA provided clinically meaningful improvements in physical function over 2 yrs, with lower discontinuation rates and larger SES for improvements in ACR and EULAR criteria components.

Abstract
PURPOSE Urethral polyps in girls are included in the differential diagnosis of interlabial masses. Only 6 cases have been described in the English literature to date and etiology is uncertain. We present 5 more cases and review the literature. We also propose an etiology for urethral polyps in young girls and compare polyps between girls and boys as well as older females. MATERIALS AND METHODS The medical records of prepubertal girls with urethral polyps seen at our hospital between 1980 and 2003, including operative reports and followup, were reviewed. A senior pathologist re-inspected the specimens to confirm the diagnosis. A MEDLINE search of urethral polyps was performed. RESULTS We identified 5 girls 2 to 10 years old with urethral polyps. All girls presented with "vaginal" bleeding, 1 had recurrent urinary tract infections and vulvitis, 1 had urinary frequency, and 1 had painful voiding. The polyps were not site specific and were located in the distal, mid and proximal urethra. All polyps were excised and were found benign. Four girls were cured after 1 procedure, while in one girl the polyp reappeared. The patients were followed for 1 to 17 years and eventually became asymptomatic. CONCLUSIONS Urethral polyps in prepubertal girls are probably benign. We suggest that the etiology of most of polyps in girls is similar to those in older females, that is a prolapsing urothelium that has evolved into a polyp.

Abstract
Lymph nodes are primary germination and proliferation sites for many types of pathogens. Maintaining therapeutic levels of appropriate chemotherapeutic agents in the lymph node tissue is critical for the treatment of both infection and cancer. This study was intended to develop a systemic route for loading lymph node phagocytes with drugs, using a lymph node specific nanocarrier. The latter is assembled as a 10-15 nm particle with a drug-carrying core and a phagocyte-homing poly(1-->6)-alpha-d-glucose based interface. Biokinetics and microdistribution of the model carrier were investigated in vivo. Nanocarrier accumulation in lymph nodes reached 30-35% dose/g in central lymph nodes, with deposition in various phagocytic cell populations. The latter included cells harboring inhaled microparticles translocated to lymph nodes from the lungs. In view of the nanocarrier ability to transport and release significant amounts of various drug substances, the data suggests feasibility of systemic drug loading to lymphatic phagocytes and, through drug release, to the neighboring cells.

In this study, we constructed epitope DNA vaccines (p3-M-38) encoding cytotoxic T lymphocyte (CTL) epitopes of MPT64 and 38 kDa proteins of Mycobacterium tuberculosis. In order to observe the influence of spacer sequence (Ala-Ala-Tyr) or ubiquitin (UbGR) on the efficacy of the two CTL epitopes, we also constructed DNA vaccines, p3-M-S(spacer)-38, p3-Ub (UbGR)-M-S-38 and p3-Ub-M-38. The immune responses elicited by the four DNA vaccines were tested in C57BL/6 (H-2b) mice. The cytotoxicity of T cells was detected by LDH-release method and by enzyme-linked immunospot assay for epitope-specific cells secreting interferon-gamma. The results showed that DNA immunization with p3-M-38 vaccine could induce epitope-specific CD8+ CTL response and that the spacer sequence (AAY) only enhanced M epitope presentation. The protein-targeting sequence (UbGR) enhanced the immunogenicity of the two epitopes. The finding that defined spacer sequences at C-terminus and protein-targeting degradation modulated the immune response of epitope string DNA vaccines will be of importance for the further development of multi-epitope DNA vaccines against tuberculosis.

Abstract
An off-line normal-phase liquid chromatography-ICP-MS method has been used for separation and determination of the rare earth elements (REE) associated with chloroplast pigments of Dicranopteris dichotoma. The stability of REE-bound pigments was tested, and almost no destruction of REE-bound pigments occurred during the so-called normal-phase liquid chromatography. The accumulated free REE ions on the microcrystalline cellulose column were cleaned by elution with 5 mmol L(-1) 2-ethylhexyl hydrogen 2-ethylhexylphosphonate (P507), to avoid exchange of these free ions with metals from the pigments. When these precautions were taken, the method was applied to the study of REE-bound pigments in D. dichotoma. ICP-MS results showed REE were present in chlorophylls and lutein, although REE concentrations in carotene and pheophytin were both below procedural blank levels. By careful analysis of the eluate fractions containing chlorophyll a it was found that REE-bound chlorophyll a in D. dichotoma was slightly enriched in the fractions with relatively short retention time. Results indicated that the retention time of REE-bound chlorophyll a might be slightly less than that of magnesium chlorophyll a, and REE-bound chlorophylls might be of relatively low polarity in comparison with magnesium bound chlorophylls. This phenomenon could be explained by the special double-decker sandwich-structure of REE-bound chlorophylls, as was reported by us and other authors. On the basis of these results we preferred to consider that REE can replace magnesium in chlorophyll a of D. dichotoma, and that the role of REE-bound chlorophylls in photosynthesis cannot be neglected. These data might be useful for understanding of both the properties of REE-bound pigments and the effect of REE on plant photosynthesis.

Abstract
A water soluble macromolecular conjugate of camptothecin (CPT) with a new, dual phase hydrolytic drug release mechanism was prepared on the basis of a 60 kDa biodegradable hydrophilic "stealth" polyacetal, poly(1-hydroxymethylethylene hydroxy-methyl formal). Succinamido-glycinate was used as a prodrug releasing group. A model preparation with 7.5% CPT content w/w was water soluble. The lipophilic camptothecin prodrug, camptothecin-(O20)-succinimidoglycinate, was released from the conjugate with t(1/2) = 2.2 +/- 0.1 h in rodent plasma. The blood clearance in a rodent model as measured by CPT was release limited, t(1/2) = 2.1 +/- 0.2 h, while the conjugate half-life was 14.2 +/- 1.7 h. In a xenograft tumor model, the conjugate demonstrated higher antineoplastic efficacy than CPT at a less than equitoxic dose. This improved therapeutic window is in line with the modified drug pharmacokinetics and with camptothecin release in a stabilized lipophilic prodrug form. Regulation of prodrug release and hydrolysis rates through linker structure modification will open the way to further improve both pharmacokinetics and pharmacodynamics.

Abstract
Various techniques using different types of catheters have been advocated to increase pregnancy rates while reducing side effects from the embryo transfer procedure. However, all of these techniques are ‘blind’ procedures of catheter introduction into the uterus, and the problems of ‘lost embryos’ and the occurrence of ectopic pregnancies persist. A novel hysteroscopic-guided direct embryo transfer procedure with visually directed embryo implantation was developed to improve the current ‘blind’ embryo transfer procedures by increasing chances of success while eliminating tubal pregnancies and decreasing high-order multiple pregnancies from IVF related techniques. At West Coast Infertility Medical Clinic, 57 patients with average age of 28.43±4.54 were analyzed. Stimulation method: controlled ovarian hyperstimulation was initiated with Follitropin β; (Follistim®, Organon Pharmaceuticals, Inc.). Premature endogenous gonadotropin surge (i.e. the prevention of an LH surge) was controlled with ganirelix acitate (AntagonTM, Organon Pharmaceuticals, Inc., West Orange, NJ, USA.). Oocyte retrieval was performed in an office setting under local anesthesia and mild sedation, followed by routine IVF/ICSI, IVC. By Day 5–6, up to 2 best quality blastocyst stage embryos were transferred to patient’s uterus by ‘hysteroscopic embryo implantation’ procedure: a lightweight hybrid (rigid/flexible) mini hysteroscope (Napoli, Inc., Los Angeles, CA, USA) was used for visualization of the endometrial cavity. The scope incorporates a flexible distal end of 3mm in diameter with a straight-through operating channel. In addition, the optic filter is directly connected to a light source, decreasing the weight of the scope and giving a better feel for the scope. The transfer catheter (Napoli, Inc.) is polycarbon based with a tapered tip (to 500μm), beveled to 60°. During embryo transfer procedure, the catheter tip was inserted into a depth of 1mm from the surface of the endometrium under direct hysteroscopic visualization. The loaded embryos with 10μL medium was released underneath the endometrium to produce a ‘bubble’ cushion. Luteal phase support was provided (3000IU of hCG at Day 3 and Day 6 post-retrieval, separately). Pregnancies were determined by serum hCG concentration of 5IUmL−1 or more at Day 16 post-retrieval. Thirty out of 57 (52.6%) women became pregnant. Multiple pregnancy rate was 4 out of 30 (13.3%) and comprised only of twins, and no ectopic pregnancy was found. In conclusion, a newly developed instrument and embryo transfer procedure by mechanical implantation of the embryo was achieved. By implanting the embryos, we have reduced the number of embryos that are transfered, minimized the chances of ‘losing’ embryos, and eliminated ectopic pregnancies.

Abstract
Considerable evidence for a role of Kupffer cells in alcoholic liver disease has accumulated and they have recently been shown to be a predominant source of free radicals. Several approaches including pharmacological agents, knockout mice, and viral gene transfer have been used to fill critical gaps in understanding key mechanisms by which Kupffer cell activation, oxidant formation, and cytokine production lead to liver damage and subsequent pathogenesis. This review highlights new data in support of the hypothesis that Kupffer cells play a pivotal role in hepatotoxicity due to ethanol by producing oxidants via NADPH oxidase.

Abstract
Vascular regression occurs during limb mesenchymal cell condensation and chondrogenesis, but it is unclear whether it is required for these processes or is a secondary phenomenon without major regulatory roles. To address this issue, beads presoaked with the potent angiogenic factor vascular endothelial growth factor (VEGF) were implanted in the vicinity of the prospective digit 2 in early chick embryo wing buds and the effects on angiogenesis and digit development were determined over time. We found that VEGF treatment caused a marked local increase in blood vessel number and density. Strikingly, this was accompanied by inhibition of digit 2 development as revealed by lack of expression of chondrogenic transcription factor Sox9 and absence of Alcian blue staining. Vascular distribution and skeletal development in adjacent areas remained largely unaffected. Inhibition of digit formation and excess vascularization were both reversible upon further embryonic growth and dissipation of VEGF activity. When supernumerary digits were induced at the anterior limb margin by retinoic acid treatment, their development was also preceded by vascular regression; interestingly, cotreatment with VEGF inhibited supernumerary digit development as well. Direct exposure of limb mesenchymal cells in micromass cultures to VEGF caused no obvious effects on condensation and chondrogenesis, indicating that VEGF effects are not due to direct action on skeletal cells. Our results are the first to provide evidence that vascular regression is required for mesenchymal condensation and chondrogenesis. A model of how patterning mechanisms and vascular regression may intersect and orchestrate limb skeletogenesis is proposed.
