Abstract
Frequency doubling of conventional fiber lasers in the near-infrared remains the most promising method for generating integrated high-peak-power lasers in the visible, while maintaining the benefits of a fiber geometry; but since the shortest wavelength power-scalable fiber laser sources are currently restricted to either the 10XX nm or 15XX nm wavelength ranges, accessing colors other than green or red remains a challenge with this schematic. Four-wave mixing using higher-order fiber modes allows for control of dispersion while maintaining large effective areas, thus enabling a power-scalable method to extend the bandwidth of near-infrared fiber lasers, and in turn, the bandwidth of potential high-power sources in the visible. Here, two parametric sources using the LP0,7 and LP0,6 modes of two step-index multi-mode fibers are presented. The output wavelengths for the sources are 880, 974, 1173, and 1347 nm with peak powers of 10.0, 16.2, 14.7, and 6.4 kW respectively, and ~300-ps pulse durations. The efficiencies of the sources are analyzed, along with a discussion of wavelength tuning and further power scaling, representing an advance in increasing the bandwidth of near-infrared lasers as a step towards high-peak-power sources at wavelengths across the visible spectrum.

Abstract
Abstract
Purpose: Hospitals face many challenges in effective care coordination for post-surgery breast cancer patients, especially with scarce resources and limited availability of nurse navigators for care transition and post-hospitalization follow up. Mobile health provides an inexpensive and convenient means of real time care monitoring and communication between patients and care providers. Nevertheless, most current health apps focus on individual consumers and gather information from their daily lives, but do not integrate with clinical workflow or capture physiological and activity data into electronic medical record for real-time monitoring, patient surveillance, and professional care. To fill this gap, we have developed and implemented MOCHA (MethOdist Hospital Cancer Health Application), a coordinated care mobile app for post-hospitalization breast cancer patients from the perspective of a primary care institution. Methods: MOCHA supports both iOS and Android platforms and contains two main modules: health care monitoring and data communication, designed together with the physicians and nurses of the Houston Methodist Cancer Center. The Health care monitoring module aims to support real-time monitoring of the post-discharge medical state of breast cancer patients. Physicians can monitor the daily food intake and activities for patients and provide advice to patients in real-time. The data communication module was developed to safely exchange the care coordination data with the hospital electronic medical record or data warehouse. Communication between the patient and the physician can be via an in-house protocol or an open data exchange standard Fast Healthcare Interoperability Resources (FHIR), that describes data format and elements for exchanging electronic health records. Our communication module uses https-based protocol to exchange the structured data with the FHIR resource server. Implementation: To validate the MOCHA app, we collaborated with the oncologists and dietitians at the Houston Methodist Cancer Center, who provided breast cancer patients for post-surgery care coordination. Our app exchanges health care data in real time with our hospital's clinical data warehouse. MOCHA searches Nutritionix food database for nutritional information and uses personal trackers such as Fitbit for patients' daily activities with their authorization. The app sends patients' daily burned calories into our clinical data warehouse. During the evaluation period, the physician communicates with cancer patients daily. In addition, every patient has a bi-weekly physical examination, and all examination results are shown in the app. After the experimental evaluation, the physician will access the data warehouse and analyze the test data in order to improve the quality of care coordination. The experimental clinical evaluation is ongoing, and we will report the results once the study is completed. Conclusion: MOCHA app provides health care monitoring and secure communication functions with interface with clinical data warehouse. The technical evaluation shows that the proposed methods are robust and efficient in support of care coordination for post-surgery cancer patients.

Abstract
The heterogeneous breast cancers can be classified into different subtypes according to their histopathological characteristics and molecular signatures. Foxa1 expression is linked with luminal breast cancer (LBC) with good prognosis, whereas Twist1 expression is associated with basal-like breast cancer (BLBC) with poor prognosis owing to its role in promoting epithelial-to-mesenchymal transition (EMT), invasiveness and metastasis. However, the regulatory and functional relationships between Twist1 and Foxa1 in breast cancer progression are unknown. In this study, we demonstrate that in the estrogen receptor (ERα)-positive LBC cells Twist1 silences Foxa1 expression, which has an essential role in relieving Foxa1-arrested migration, invasion and metastasis of breast cancer cells. Mechanistically, Twist1 binds to Foxa1 proximal promoter and recruits the NuRD transcriptional repressor complex to de-acetylate H3K9 and repress RNA polymerase II recruitment. Twist1 also silences Foxa1 promoter by inhibiting AP-1 recruitment. Twist1 expression in MCF7 cells silenced Foxa1 expression, which was concurrent with the induction of EMT, migration, invasion and metastasis of these cells. Importantly, restored Foxa1 expression in these cells largely inhibited Twist1-promoted migration, invasion and metastasis. Restored Foxa1 expression did not change the Twist1-induced mesenchymal cellular morphology and the expression of Twist1-regulated E-cadherin, β-catenin, vimentin and Slug, but it partially rescued Twist1-silenced ERα and cytokeratin 8 expression and reduced Twist1-induced integrin α5, integrin β1 and MMP9 expression. In a xenografted mouse model, restored Foxa1 also increased Twist1-repressed LBC markers and decreased Twist1-induced BLBC markers. Furthermore, Twist1 expression is negatively correlated with Foxa1 in the human breast tumors. The tumors with high Twist1 and low Foxa1 expressions are associated with poor distant metastasis-free survival. These results demonstrate that Twist1's silencing effect on Foxa1 expression is largely responsible for Twist1-induced migration, invasion and metastasis, but less responsible for Twist1-induced mesenchymal morphogenesis and expression of certain EMT markers.

Abstract
In this study, we evaluated the efficacy and safety of high-dose calcium channel blocker (CCB) monotherapy and standard-dose CCBs combined with angiotensin receptor blockers (ARBs) for patients with hypertension. A comprehensive search of PubMed, Embase and the Cochrane Central Register of Controlled Trials was performed in December 2015. Randomized controlled trials designed to identify the above goal were included. Thirteen trials including 2371 patients were identified. The standard-dose CCB/ARB combination resulted in a greater reduction of systolic blood pressure (WMD -2.52, 95% confidence interval (CI): -3.76 to -1.28) and diastolic blood pressure (weighted mean difference (WMD) -2.07, 95% CI: -3.73 to -0.42) compared to high-dose CCB monotherapy. The overall hypertension control rate for the CCB/ARB combination was higher than that for CCB monotherapy (relative risk (RR): 1.17, 95% CI: 1.08-1.26). Furthermore, the CCB/ARB combination treatment yielded significantly fewer overall adverse events (RR: 0.84, 95% CI: 0.74-0.95), oedema (RR: 0.31; 95% CI: 0.18-0.52) and rash (RR: 0.27, 95% CI: 0.08-0.96, P=0.04) than did CCB monotherapy. The standard-dose CCB/ARB combination is superior to high-dose CCB monotherapy for lowering blood pressure and reducing adverse events in hypertensive patients. Future research should focus on the cost-effectiveness and long-term effects of these two treatment strategies for patients with hypertension.

Abstract
Objectives The aim of these investigations was to assess the ability of two fluoride dentifrices to protect against the initiation and progression of dental erosion using a predictive in vitro erosion cycling model and a human in situ erosion prevention clinical trial for verification of effectiveness. Materials and methods A stabilized stannous fluoride (SnF2) dentifrice (0.454 % SnF2 + 0.077 % sodium fluoride [NaF]; total F = 1450 ppm F) [dentifrice A] and a sodium monofluorophosphate [SMFP]/arginine dentifrice (1.1 % SMFP + 1.5 % arginine; total F = 1450 ppm F) [dentifrice B] were tested in a 5-day in vitro erosion cycling model and a 10-day randomized, controlled, double-blind, two-treatment, four-period crossover in situ clinical trial. In each study, human enamel specimens were exposed to repetitive product treatments using a standardized dilution of test products followed by erosive acid challenges in a systematic fashion. Results Both studies demonstrated statistically significant differences between the two products, with dentifrice A providing significantly better enamel protection in each study. In vitro, dentifrice A provided a 75.8 % benefit over dentifrice B (p < 0.05, ANOVA), while after 10 days in the in situ model, dentifrice A provided 93.9 % greater protection versus dentifrice B (p < 0.0001, general linear mixed model). Conclusion These results support the superiority of stabilized SnF2 dentifrices for protecting human teeth against the initiation and progression of dental erosion. Clinical relevance Stabilized SnF2 dentifrices may provide more significant benefits to consumers than conventional fluoride dentifrices.

Abstract
OBJECTIVE Retinoic acid has been shown to improve the aged-appearing skin. However, less is known about the anti-ageing effects of retinol (ROL, vitamin A), a precursor of retinoic acid, in aged human skin in vivo. This study aimed to investigate the molecular basis of ROL anti-ageing properties in naturally aged human skin in vivo. METHODS Sun-protected buttock skin (76 ± 6 years old, n = 12) was topically treated with 0.4% ROL and its vehicle for 7 days. The effects of topical ROL on skin epidermis and dermis were evaluated by immunohistochemistry, in situ hybridization, Northern analysis, real-time RT-PCR and Western analysis. Collagen fibrils nanoscale structure and surface topology were analysed by atomic force microscopy. RESULTS Topical ROL shows remarkable anti-ageing effects through three major types of skin cells: epidermal keratinocytes, dermal endothelial cells and fibroblasts. Topical ROL significantly increased epidermal thickness by stimulating keratinocytes proliferation and upregulation of c-Jun transcription factor. In addition to epidermal changes, topical ROL significantly improved dermal extracellular matrix (ECM) microenvironment; increasing dermal vascularity by stimulating endothelial cells proliferation and ECM production (type I collagen, fibronectin and elastin) by activating dermal fibroblasts. Topical ROL also stimulates TGF-β/CTGF pathway, the major regulator of ECM homeostasis, and thus enriched the deposition of ECM in aged human skin in vivo. 0.4% topical ROL achieved similar results as seen with topical retinoic acid, the biologically active form of ROL, without causing noticeable signs of retinoid side effects. CONCLUSION 0.4% topical ROL shows remarkable anti-ageing effects through improvement of the homeostasis of epidermis and dermis by stimulating the proliferation of keratinocytes and endothelial cells, and activating dermal fibroblasts. These data provide evidence that 0.4% topical ROL is a promising and safe treatment to improve the naturally aged human skin.

Abstract
Abstract
Twist1, a basic helix-loop-helix transcription factor, plays a key role to mediate epithelial-mesenchymal transition (EMT) and promote breast cancer metastasis. However, knowledge about Twist1 structure-function relationships to cancer-related phenotypes is limited. Therefore, we studied the requirement of Twist1 N-terminus in Twist1-dependent breast cancer metastasis. We showed that the amino-terminus of Twist1 was the dominant negative mutant of Twist1. Overexpression of Twist1 N-terminus exhibited different cell morphology and motility in vitro. Inoculation of Twist1 N-terminus overexpression cells into SCID mice showed delayed tumor formation and reduced lung metastasis. Furthermore, Twist1 N-terminus overexpression induced expression change of EMT markers, including E-cadherin, β-catenin, vimentin and Twist1 both in vivo and in vitro. Co-immunoprecipitation and mass spectrometry revealed that Twist1 N-terminus interacted with several members of the Mi2/nucleosome remodeling and deacetylase (Mi2/NuRD) complex, HDAC2, 3 and 7, MTA1 and 2, RbAp46/48, and many corepressors including NCoR1 and 2, which released them from the proximal region of E-cadherin promoter for transcriptional activation. These data suggest that Twist1 N-terminus is required for Twist1-mediated transcriptional programs and breast cancer metastasis.

Abstract
This study investigated whether there was a difference in amounts of dentifrice ingested by children based on age using pea-sized instructions. The study had a randomized, single-blinded, 3-period, crossover design modelled after Barnhart et al. (1974) with one regular-flavored and two specially-flavored dentifrices used ad libitum. Subjects were enrolled in three groups: 2-4, 5-7, and 8-12 years. They were instructed to brush at home as they would normally with each dentifrice for 3 weeks (9 weeks total). On weekly study-site visits, subjects brushed with the assigned dentifrice containing a lithium marker to measure the amount of dentifrice ingested and used. Averaging across dentifrices, amounts ingested were: 0.205 g (2-4 yr), 0.125 g (5-7 yr) and 0.135 g (8-12 yr), demonstrating 2-4 year-olds ingested significantly more than older children (p ≤ 0.002). Averaging across dentifrices, amounts used were: 0.524 g (2-4 yr), 0.741 g (5-7 yr) and 0.978 g (8-12 yr) suggesting an age-related effect (p < 0.01). Findings also showed that ingestion amount for specially-flavored dentifrices may increase relative to regular-flavored dentifrice for children 2-7 years-old. This research demonstrated that dentifrice ingestion amount decreased significantly with age while usage amount increased with age. Importantly, ingestion and usage levels in younger children reflect "pea-sized" direction and were numerically lower than historical levels reported prior to this direction.

Abstract
We investigated the expression and effects of hypoxia-inducible factor-1α (HIF-1α) in rat thromboangiitis obliterans (TO). Rats were divided into sham and model groups. The model group was further divided into groups based on observation duration. Lauric acid was injected below an artery clamp to simulate TO in the model group; saline was used in the sham group. Clamps were removed 15 min after injection in both groups, and physiological changes were observed at different times (gross observation and hematoxylin and eosin staining). The animals were killed at various times following the operation and serum and muscle tissues were sampled. For the sham group: the endometrium was relatively intact; medial membrane and epineurium lesions were absent; and blood vessels and surrounding tissues had no inflammatory cell infiltration. For the model group: all subgroups displayed inflammation; large numbers of inflammatory cells were gathered; muscle tissue lost its normal texture and structure; and the internal elastic membrane was integrated. Compared with the preoperative status, HIF-1α expression increased significantly in all subgroups (P < 0.05); there was no change in the sham group. HIF-1α expression in each subgroup was different (F = 14.267, P < 0.05). Femoral artery injection of lauric acid can be used as a rat TO model owing to its simple application and success rate. HIF-1α expression increased in the early stage of TO and gradually decreased with the extension of ischemia time; it may play a leading role in TO development and can be used for diagnosis and cure evaluation.

Abstract
BACKGROUND AND OBJECTIVE Bacteremia and systemic inflammatory markers are associated with periodontal and systemic diseases and may be linking mechanisms between these conditions. We hypothesized that in the development of gingival inflammation, systemic markers of inflammation and bacteremia would increase. MATERIAL AND METHODS To study the effect of bacteremia on systemic inflammatory markers, we recruited 80 subjects to participate in an experimental gingivitis study. Subjects were stratified based on gender, smoking and the number of bleeding sites and then randomized to one of two groups: control group (n = 40) or experimental gingivitis group (n = 40). Subjects in the control group conducted an oral hygiene regimen: brushing twice daily with a regular sodium fluoride cavity protection dentifrice and a standard manual toothbrush, flossing twice daily, and mouth rinsing with an anti-cavity fluoride rinse once daily. The experimental group stopped brushing and flossing, and used only the fluoride anti-cavity mouth rinse for 21 d. RESULTS Seventy-nine of 80 subjects were evaluable. One subject in the control group was excluded from the results due to antibiotic use during the study. Our data showed the experimental gingivitis group exhibited a significant (p < 0.05) increase in dental plaque level and gingival inflammatory indices relative to baseline and the control group but a decrease in bacteremia and soluble intercellular adhesion molecule-1 levels vs. baseline. Bacteremia was negatively correlated with gingival inflammatory indices and soluble intercellular adhesion molecule-1 levels in the experimental gingivitis group, thus negating our hypothesis. CONCLUSION We conclude that there are marked differences in systemic cytokine levels over the course of short-term experimentally induced gingivitis and further conclude that a long-term periodontitis study must be considered to address mechanisms whereby oral diseases may affect systemic diseases.

Abstract
Sex determining region Y-box 11 (SOX11) expression is specific for mantle cell lymphoma (MCL) as compared with other non-Hodgkin's lymphomas. However, the function and direct-binding targets of SOX11 in MCL are largely unknown. We used high-resolution chromatin immunoprecipitation sequencing to identify the direct target genes of SOX11 in a genome-wide, unbiased manner and elucidate its functional significance. Pathway analysis identified WNT, PKA and TGF-beta signaling pathways as significantly enriched by SOX11-target genes. Quantitative chromatin immunoprecipitation sequencing and promoter reporter assays confirmed that SOX11 directly binds to individual genes and modulates their transcription activities in these pathways in MCL. Functional studies using RNA interference demonstrate that SOX11 directly regulates WNT in MCL. We analyzed SOX11 expression in three independent well-annotated tissue microarrays from the University of Wisconsin (UW), Karolinska Institute and British Columbia Cancer Agency. Our findings suggest that high SOX11 expression is associated with improved survival in a subset of MCL patients, particularly those treated with intensive chemotherapy. Transcriptional regulation of WNT and other biological pathways affected by SOX11-target genes may help explain the impact of SOX11 expression on patient outcomes.

Abstract
Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL/TNFSF10/Apo2L) holds promise for cancer therapy as it induces apoptosis in a large variety of cancer cells while exerting negligible toxicity in normal ones. However, TRAIL can also induce proliferative and migratory signaling in cancer cells resistant to apoptosis induced by this cytokine. In that regard, the molecular mechanisms underlying the tumor selectivity of TRAIL and those balancing apoptosis versus survival remain largely elusive. We show here that high mRNA levels of PLAU, which encodes urokinase plasminogen activator (uPA), are characteristic of cancer cells with functional TRAIL signaling. Notably, decreasing uPA levels sensitized cancer cells to TRAIL, leading to markedly increased apoptosis. Mechanistic analyses revealed three molecular events taking place in uPA-depleted cells: reduced basal ERK1/2 prosurvival signaling, decreased preligand decoy receptor 2 (DcR2)-death receptor 5 (DR5) interaction and attenuated recruitment of DcR2 to the death-inducing signaling complex upon TRAIL challenge. These phenomena were accompanied by increased FADD and procaspase-8 recruitment and processing, thus guiding cells toward a caspase-dependent cell death that is largely independent of the intrinsic apoptosis pathway. Collectively, our results unveil PLAU mRNA levels as marker for the identification of TRAIL-responsive tumor cells and highlight a key role of uPA signaling in ‘apoptosis versus survival' decision-making processes upon TRAIL challenge.

Abstract
Anhydrous methanol, a traditional precipitant for poly(n-butyl methacrylate), has been shown to be an excellent synthesis solvent using ATRP, generating high molecular weights and low dispersities (up to 76 000 g mol−1 and as low as 1.02).
