The first complete mitochondrial genome of the sand dollar Sinaechinocyamus mai (Echinoidea: Clypeasteroida).

Morphologic and molecular data often lead to different hypotheses of phylogenetic relationships. Such incongruence has been found in the echinoderm class Echinoidea. In particular, the phylogenetic status of the order Clypeasteroida is not well resolved. Complete mitochondrial genomes are currently available for 29 echinoid species, but no clypeasteroid had been sequenced to date. DNA extracted from a single live individual of Sinaechinocyamus mai was sequenced with 10× Genomics technology. This first complete mitochondrial genome (mitogenome) for the order Clypeasteroida is 15,756 base pairs in length. Phylogenomic analysis based on 34 ingroup taxa belonging to nine orders of the class Echinoidea show congruence between our new genetic inference and published trees based on morphologic characters, but also includes some intriguing differences that imply the need for additional investigation.

Proteomic Analysis Reveals Anti-Fibrotic Effects of Blue Light Photobiomodulation on Fibroblasts.

BACKGROUND AND OBJECTIVES: This study was aimed at determining the effects of blue light photobiomodulation on primary adult mouse dermal fibroblasts (AMDFs) and the associated signaling pathways. STUDY DESIGN/MATERIALS AND METHODS: Cultured AMDFs from adult C57BL/6 mice were irradiated by blue light from a light-emitting diode (wavelength = 463 ± 50 nm; irradiance = 5 mW/cm2 ; energy density = 4-8 J/cm2 ). The cells were analyzed using mass spectrometry for proteomics/phosphoproteomics, AlamarBlue assay for mitochondrial activity, time-lapse video for cell migration, quantitative polymerase chain reaction for gene expression, and immunofluorescence for protein expression. RESULTS: Proteomic/phosphoproteomic analysis showed inhibition of extracellular signal-regulated kinases/mammalian target of rapamycin and casein kinase 2 pathways, cell motility-related networks, and multiple metabolic processes, including carbon metabolism, biosynthesis of amino acid, glycolysis/gluconeogenesis, and the pentose phosphate pathway. Functional analysis demonstrated inhibition of mitochondrial activities, cell migration, and mitosis. Expression of growth promoting insulin-like growth factor 1 and fibrosis-related genes, including transforming growth factor ß1 (TGFß1) and collagen type 1 ɑ2 chain diminished. Protein expression of α-smooth muscle actin, an important regulator of myofibroblast functions, was also suppressed. CONCLUSIONS: Low-level blue light exerted suppressive effects on AMDFs, including suppression of mitochondrial activity, metabolism, cell motility, proliferation, TGFß1 levels, and collagen I production. Low-level blue light can be a potential treatment for the prevention and reduction of tissue fibrosis, such as hypertrophic scar and keloids. Lasers Surg. Med. © 2019 Wiley Periodicals, Inc.

Changing surface ocean circulation caused the local demise of echinoid Scaphechinus mirabilis in Taiwan during the Pleistocene-Holocene transition.

Abundant fossil specimens of Scaphechinus mirabilis, now occurring mostly in temperate waters, have been found in the Toukoshan Formation (Pleistocene) in Miaoli County, Taiwan. Environmental changes leading to its extirpation (local extinction) have thus far been elusive. Here, we reconstruct past environmental and oceanic conditions off northwest Taiwan by analyzing clumped isotopes, as well as stable oxygen isotopes, of well-preserved fossil echinoid tests collected from the Toukoshan Formation. Radiocarbon dates suggest that these samples are from Marine Isotope Stage 3 (MIS 3). Paleotemperature estimates based on clumped isotopes indicate that fossil echinoids were living in oceanic conditions that range from 9 to 14 °C on average, comparable with the estimate derived for a modern sample from Mutsu Bay, Japan. Notably, this temperature range is ~ 10 °C colder than today's conditions off northwest Taiwan. The substantially lower temperatures during ~ 30 ka (MIS 3) compared to the modern conditions might be due to the rerouting of surface currents off northwest Taiwan when the sea level was ~ 60 m lower than today, in addition to the cooling caused by a lower atmospheric CO2 level during the Last Glacial Period. Colder waters brought here by the China Coastal Current (CCC) and the existence of shallow subtidal zones termed "Miaoli Bay" (mainly located in the present-day Miaoli county) during MIS 3 plausibly sustained generations of S. mirabilis, yielding tens of thousands of fossil specimens in the well-preserved fossil beds. The likely extirpation driver is the drastic change from a temperate climate to much warmer conditions in the shallow sea during the Pleistocene-Holocene transition.

Fracture types affect clinical outcomes of patients managed within the fracture liaison and osteoporosis medication management services.

Osteoporosis medication in fragility fracture patients is associated with better outcomes. However, limited studies have investigated whether fracture types affect outcomes among patients undergoing treatment. We performed a secondary data analysis on participants from a fracture liaison service and an osteoporosis medication management service. Participants (n = 974) were regrouped into hip fracture (HF), vertebral fracture (VF), HF + VF, and NO HF/VF groups at baseline. Bivariate and multivariate logistic regressions were performed to identify baseline correlates on one-year mortality, incident refractures, and falls. Baseline characteristics were different among fracture groups. The HF group was oldest, with the lowest body mass index (BMI), lowest FRAX® T-score and had the highest 10-year fracture risk. After intervention, the HF group still had the highest mortality, but the HF + VF group had the highest refracture and incident fall rates. In the multivariate regression analysis, prevalent HF and VF, lower BMI and albumin level, and having chronic kidney disease or cancer were associated with higher mortality rates. HF + VF patients had the highest refracture risk. Prevalent HF and VF, older age and higher BMI, and having cancer or osteoarthritis were associated with a greater fall risk. HF and VF are associated with adverse outcomes, even under an optimal fracture care.

The updated PIM-Taiwan criteria: a list of potentially inappropriate medications in older people.

BACKGROUND: Explicit criteria for potentially inappropriate medications (PIMs) developed for other countries are difficult to apply to a specific territory. This study aimed to update the PIM-Taiwan criteria from a qualitative review of several published PIM criteria, followed by consensus among regional experts in Taiwan. METHODS: After a review of the literature, we selected four sets of published PIM criteria to construct preliminary core PIMs. The Beers criteria, Fit fOR The Aged (FORTA), and Japan criteria were used for PIMs, without consideration of chronic diseases. The Beers criteria, Screening Tool of Older Persons' Prescriptions (STOPP) criteria, and Japan criteria were used for PIMs with respect to chronic diseases. We asked experts (n = 24) to rate their agreement with each statement, including in the final PIM criteria, after two rounds of modified Delphi methods. The intraclass coefficient (ICC) was used to examine the reliability of the modified Delphi method. RESULTS: Overall, two categories of PIMs were established: 131 individual drugs and 9 drugs with combinations that should generally be avoided; and 9 chronic diseases with their corresponding PIMs that have drug-disease interactions. The ICC estimates for PIMs to be avoided generally were 0.634 and 0.557 (round 1 and 2) and those for PIMs with respect to chronic diseases were 0.866 and 0.775 (round 1 and 2) of the Delphi method, respectively. CONCLUSIONS: The 2018 version of PIM-Taiwan criteria was established and several modifications were made to keep the criteria updated and relevant. Clinicians can use them to reduce polypharmacy and PIMs among older patients.

Stout camphor tree genome fills gaps in understanding of flowering plant genome evolution.

We present reference-quality genome assembly and annotation for the stout camphor tree (Cinnamomum kanehirae (Laurales, Lauraceae)), the first sequenced member of the Magnoliidae comprising four orders (Laurales, Magnoliales, Canellales and Piperales) and over 9,000 species. Phylogenomic analysis of 13 representative seed plant genomes indicates that magnoliid and eudicot lineages share more recent common ancestry than monocots. Two whole-genome duplication events were inferred within the magnoliid lineage: one before divergence of Laurales and Magnoliales and the other within the Lauraceae. Small-scale segmental duplications and tandem duplications also contributed to innovation in the evolutionary history of Cinnamomum. For example, expansion of the terpenoid synthase gene subfamilies within the Laurales spawned the diversity of Cinnamomum monoterpenes and sesquiterpenes.

The development of Taiwan Fracture Liaison Service network.

Osteoporosis and its associated fragility fractures are becoming a severe burden in the healthcare system globally. In the Asian-Pacific (AP) region, the rapidly increasing in aging population is the main reason accounting for the burden. Moreover, the paucity of quality care for osteoporosis continues to be an ongoing challenge. The Fracture Liaison Service (FLS) is a program promoted by International Osteoporosis Foundation (IOF) with a goal to improve quality of postfracture care and prevention of secondary fractures. In this review article, we would like to introduce the Taiwan FLS network. The first 2 programs were initiated in 2014 at the National Taiwan University Hospital and its affiliated Bei-Hu branch. Since then, the Taiwan FLS program has continued to grow exponentially. Through FLS workshops promoted by the Taiwanese Osteoporosis Association (TOA), program mentors have been able to share their valuable knowledge and clinical experience in order to promote establishments of additional programs. With 22 FLS sites including 11 successfully accredited on the best practice map, Taiwan remains as one of the highest FLS coverage countries in the AP region, and was also granted the IOF Best Secondary Fracture Prevention Promotion award in 2017. Despite challenges faced by the TOA, we strive to promote more FLS sites in Taiwan with a main goal of ameliorating further health burden in managing osteoporotic patients.

Consensus on best practice standards for Fracture Liaison Service in the Asia-Pacific region.

The Fracture Liaison Service (FLS) Consensus Meeting endorsed by the International Osteoporosis Foundation (IOF), Asian Federation of Osteoporosis Societies (AFOS), and Asia Pacific Osteoporosis Foundation (APOF) was hosted by the Taiwanese Osteoporosis Association on October 14, 2017. International and domestic experts reviewed the 13 Best Practice Framework (BPF) standards and concluded that all standards were generally applicable in the Asia-Pacific region and needed only minor modifications to fit the healthcare settings in the region. PURPOSE: To review and generate consensus on best practices of fracture liaison service (FLS) in the Asia-Pacific (AP) region. METHODS: In October 2017, the Taiwanese Osteoporosis Association (TOA) invited experts from the AP region (n = 23), the Capture the Fracture Steering Committee (n = 2), and the USA (n = 1) to join the AP region FLS Consensus Meeting in Taipei. After two rounds of consensus generation, the recommendations on the 13 Best Practice Framework (BPF) standards were reported and reviewed by the attendees. Experts unable to attend the on-site meeting reviewed the draft, made suggestions, and approved the final version. RESULTS: Because the number of FLSs in the region is rapidly increasing, experts agreed that it was timely to establish consensus on benchmark quality standards for FLSs in the region. They also agreed that the 13 BPF standards and the 3 levels of standards were generally applicable, but that some clarifications were necessary. They suggested, for example, that patient and family education be incorporated into the current standards and that communication with the public to promote FLSs be increased. CONCLUSIONS: The consensus on the 13 BPF standards reviewed in this meeting was that they were generally applicable and required only a few advanced clarifications to increase the quality of FLSs in the region.
