In conclusion, KCNQ1OT1/miR-29c-3p/FOS axis played a vital role in the progression of ARC.Hydrothermal liquefaction is a promising technology to upgrade wet organic waste into a biocrude oil for diesel or jet fuel; however, this process generates an acid-rich aqueous phase which poses disposal issues. This hydrothermal liquefaction aqueous phase (HTL-AP) contains organic acids, phenol, and other toxins. This work demonstrates that Y. lipolytica as a unique host to valorize HTL-AP into a variety of co-products. Specifically, strains of Y. lipolytica can tolerate HTL-AP at 10% in defined media and 25% in rich media. The addition of HTL-AP enhances production of the polymer precursor itaconic acid by 3-fold and the polyketide triacetic acid lactone at least 2-fold. selleck chemicals llc Additional co-products (lipids and citric acid) were produced in these fermentations. Finally, bioreactor cultivation enabled 21.6 g/L triacetic acid lactone from 20% HTL-AP in mixed sugar hydrolysate. These results demonstrate the first use of Y. lipolytica in HTL-AP valorization toward production of a portfolio of value-added compounds.The last decade has seen an increased interest in the discovery of compounds with bone anabolic activity to treat skeletal disorders such as osteoporosis and increase the well-being of patients. Due to the many technical advantages over classical rodent systems, zebrafish (Danio rerio) has been increasingly used in screening pipelines, in particular those aiming at identifying osteoactive compounds with pharmacological potential. Because compound osteoactivity is mostly determined in zebrafish through the morphometric analysis of bone structures, image analysis, rather than screening assay implementation, molecule availability and image acquisition, represents a bottleneck to the screening throughput. The absence of auto/semi-automatic tools for image analysis of fish bone structures is also a limitation to a broader usage of zebrafish screening pipelines. We present here ZFBONE (for ZebraFish BONE), an open-source, freely available, user-friendly, rapid and reliable toolset, aiming at accelerating image analysis by automating the morphometric assessment of zebrafish bone structures, but also at increasing data accuracy by reducing operator bias. Tools included in ZFBONE allow users to assess, from 2D images, morphometric parameters of several bone structures (e.g. operculum, caudal fin rays and scales) but also the extent and the intensity of bone-specific colorations. ZFBONE has been developed using the open-source ImageJ software, to make it available to the whole zebrafish research community, but also to have it easily modifiable according to user demands. ZFBONE can also be used toward the standardization of zebrafish screening protocols in academia and industry.Introduction Reports of elevated bone mass (EBM) on routine DXA scanning are not infrequent. However, epidemiological studies of EBM are few in number and definition thresholds variable. The purpose of this study was to assess the prevalence and causes of EBM in the general population referred to a single university hospital - catering for a population of 4 million inhabitants - for DXA scanning. Material and methods DXA databases were initially searched for individuals with a bone mineral density (BMD) Z-score ≥+4 at any site in the lumbar spine or hip from April 1st, 2008 to April 30st, 2018. Two Hologic scanners were available at the Lille University Hospital (France). Prevalence of EBM was evaluated, as were causes associated with EBM. Results At the lumbar spine, 18,229 bone density tests were performed in women and 10,209 in men. At the hip, 17,390 tests were performed in women and 9857 in men. The total number of patients who had at least one bone density test was 14,745, of which 64.2% were female. Ofedical record and through conventional investigations. This study suggests that the main cause of EBM is degenerative disease of the spine. Further studies are needed to differentiate artefactual EBM from hereditary or acquired EBM, and to investigate unexplained EBM. Genetic testing may prove useful in elucidating rare unknown causes.Introduction In women with postmenopausal osteoporosis denosumab discontinuation is associated with rapid bone loss that could be potentially prevented by a single zoledronate infusion for two years. The longer-term effects, however, of zoledronate treatment are unknown. We aimed to study the effect of a single zoledronate infusion during the third year following denosumab discontinuation, in initially treatment-naive postmenopausal women who became osteopenic after 2.4 ± 0.2 years of denosumab therapy. Methods We report the 1-year follow-up results of a single arm observational extension of a previously reported 2-year multicenter prospective randomized clinical trial. The primary endpoint of this extension was the change in lumbar spine bone mineral density (LS-BMD); secondary endpoints were changes in femoral neck (FN)-BMD and markers of bone turnover (BTM) during the 3rd year from the zoledronate infusion. Changes are presented as mean and SEM. Results LS-BMD did not change significantly at year 3 compared to year 2 (-1.35 ± 1.1%, p = 1.00) and compared to baseline (-1.96 ± 1.44%, p = 1.00). FN-BMD values did not change while serum P1NP values decreased and CTX values remained unchanged during the third-year of the follow-up. In 4 of the 23 studied women BMD values returned to the osteoporotic range at 3 years. Conclusions A single i.v. infusion of zoledronate 5 mg, given 6 months after the last injection of denosumab therapy maintains for three years BMD gains in the majority of patients previously treated with denosumab for an approximate period of 2.5 years. Follow-up of patients is, however, recommended because about one-fifth of treated women will require additional antiosteoporotic treatment.Adventitious roots form from non-root tissues as part of normal development or in response to stress or wounding. The root primordia form in the source tissue, and during emergence the adventitious roots penetrate the inner cell layers and the epidermis; however, the mechanisms underlying this emergence remain largely unexplored. Here, we report that a regulatory module composed of the AP2/ERF transcription factor ABSCISIC ACID INSENSITIVE 4 (ABI4), the MAP kinases MPK3 and MPK6, and the phosphatase PP2C12 plays an important role in the emergence of junction adventitious roots (J-ARs) from the root-hypocotyl junctions in Arabidopsis thaliana. ABI4 negatively regulates J-AR emergence, preventing the accumulation of reactive oxygen species and death of epidermal cells, which would otherwise facilitate J-AR emergence. Phosphorylation by MPK3/MPK6 activates ABI4 and dephosphorylation by PP2C12 inactivates ABI4. MPK3/MPK6 also directly phosphorylate and inactivate PP2C12 during J-AR emergence. We propose that this "double-check" mechanism increases the robustness of MAP kinase signaling and finely regulates the local programmed cell death required for J-AR emergence.
