The use of tamoxifen-inducible models of Cre recombinase in the tendon field is rapidly expanding, resulting in an enhanced understanding of tendon homeostasis and healing. However, the effects of tamoxifen on the tendon are not well-defined, which is particularly problematic given that tamoxifen can have both profibrotic and antifibrotic effects in a tissue-specific manner. Therefore, in the present study, we examined the effects of tamoxifen on tendon homeostasis and healing in male and female C57Bl/6J mice. Tamoxifen-treated mice were compared to corn oil (vehicle)-treated mice. In the "washout" treatment regimen, mice were treated with tamoxifen or corn oil for 3 days beginning 1 week prior to undergoing complete transection and surgical repair of the flexor digitorum longus tendon. In the second regimen, mice were treated with tamoxifen or corn oil beginning on the day of surgery, daily through day 2 postsurgery, and every 48 hours thereafter (D0-2q48) until harvest. All repaired tendons and uninjured contralateral control tendons were harvested at day 14 postsurgery. Tamoxifen treatment had no effect on tendon healing in male mice, regardless of the treatment regimen, while Max load was significantly decreased in female repairs in the Tamoxifen washout group, relative to corn oil. In contrast, D0-2q48 corn oil treatment in female mice led to substantial disruptions in tendon homeostasis, relative to washout corn oil treatment. Collectively, these data clearly define the functional effects of tamoxifen and corn oil treatment in the tendon and inform future use of tamoxifen-inducible genetic models.Issue addressed Little is known about the complex relationships between Australian Indigenous people's use of social media and "health-seeking" - seeking help for issues related to health and well-being. This paper has emerged from a broader sociological research project focusing on the help-seeking and help-giving practices of Aboriginal and Torres Strait Islander people on social media, specifically aiming to unlock its potential to create vital and creative connections between help-seekers and help-givers. Methods Semi-structured interviews were conducted with 52 Indigenous Facebook users from five sites across Australia. Results The use of grounded theory and Indigenous-centred methodologies for analysis showed clearly that users draw on the connections made possible through Facebook to health-seek. We identify five primary health-seeking strategies that differ in form, purpose and directness soliciting health-related information, gaining emotional support, producing social health-seeking collectives, engaging in motivational and "eudaimonic" content, and connecting with formal health sources. Conclusion While far from being a panacea to health disparities, these findings show that Facebook does provide unique opportunities for many Indigenous help-seekers and help-givers in times of need. SO WHAT? Social media offers pathways for health-seeking both beyond and outside the dominant western biomedical models of public health promotion. These already-existing pathways should be considered by people working on social media public health promotion campaigns for Aboriginal and Torres Strait Islander people.Objective Microneedle patches based on dissolving, detachable micro-needle technology (Russian patent No. 2652567; US patent EFS No. 32735812; WO/2019/231360) are novel dermatological products that allow safe, painless and effective reduction of epidermal wrinkles after 6 procedures. The purpose of this study was two-fold a) to assess the safety and efficacy of micro-needle patches comprising 650 micro-needles containing hyaluronic and ferulic acids after 6 procedures of applying the applicator to the skin for 25 minutes; and b) to correlate our previously reported ex-vivo findings. AZD5438 ic50 Methods The micro-needle applicator contains 650 micro-needles, which dissolve in 25 minutes of exposure. The effectiveness of micro-needle applicators was confirmed by a randomized split-phase study involving 82 subjects. Applications of micro-needle patches were performed at intervals of 2 times per week, and the effectiveness was assessed at 6 weeks after the start of the study. Results The results of the profilometric evaluati of the injected hyaluronic acid and other active components, as well as to detail the mechanism of action of soluble micro-needles to improve skin quality.Cancer is driven by genetic mutations in oncogenes and tumor suppressor genes and by cellular events that develop a misregulated molecular microenvironment in the growing tumor tissue. The tumor microenvironment is guided by the excessive action of specific cytokines including transforming growth factor-β (TGF-β), which normally controls embryonic development and the homeostasis of young or adult tissues. As a consequence of the genetic alterations generating a given tumor, TGF-β can preserve its homeostatic function and attempt to limit neoplastic expansion, whereas, once the tumor has progressed to an aggressive stage, TGF-β can synergize with various oncogenic stimuli to facilitate tumor invasiveness and metastasis. TGF-β signaling mechanisms via Smad proteins, various ubiquitin ligases, and protein kinases are relatively well understood. Such mechanisms regulate the expression of genes encoding proteins or non-coding RNAs. Among non-coding RNAs, much has been understood regarding the regulation and function of microRNAs, whereas the role of long non-coding RNAs is still emerging. This article emphasizes TGF-β signaling mechanisms leading to the regulation of non-coding genes, the function of such non-coding RNAs as regulators of TGF-β signaling, and the contribution of these mechanisms in specific hallmarks of cancer.Co-occurring and mutually exclusive gene alteration events are helpful for understanding carcinogenesis but systematic screening for such events is quite limited. We conducted pairwise-screening tests to identify "hit pairs" in colorectal cancer (CRC) by utilizing the cross-omics data from the Cancer Genome Atlas (TCGA). Numerous hit pairs involving somatic mutations, CNVs and DNA methylation were found to occur non-randomly in CRC, such as KRAS and HOXB6, SMAD4 and PMEPA1. Based on these hit pairs, we identified 32 synthetic lethal pairs and 7,527 co-occurring pairs relating to drug response. Our further biological experiments showed that the co-occurrence of mutant FCGBP and NUDT12 silencing (or mutant TMC3 and RPS6KA6 silencing) with siRNA reduced cell viability. Moreover, novel hit pairs could influence the prognosis. The patients who carried concurrent mutations of IRF5 and NEFH, SYNE1 and TTN, or MUC16 and NEFH had worse survival outcomes. Particularly, the presence of mutant SYNE1 and TTN pair not only affects prognosis, but also is related to CRC patients' response to drug treatment.
