We present BISTRO Survey 850 {\mu}m dust emission polarisation observations of the L1495A-B10 region of the Taurus molecular cloud, taken at the JCMT. We observe a roughly triangular network of dense filaments. We detect 9 of the dense starless cores embedded within these filaments in polarisation, finding that the plane-of-sky orientation of the core-scale magnetic field lies roughly perpendicular to the filaments in almost all cases. We also find that the large-scale magnetic field orientation measured by Planck is not correlated with any of the core or filament structures, except in the case of the lowest-density core. We propose a scenario for early prestellar evolution that is both an extension to, and consistent with, previous models, introducing an additional evolutionary transitional stage between field-dominated and matter-dominated evolution, observed here for the first time. In this scenario, the cloud collapses first to a sheet-like structure. Uniquely, we appear to be seeing this sheet almost face-on. The sheet fragments into filaments, which in turn form cores. However, the material must reach a certain critical density before the evolution changes from being field-dominated to being matter-dominated. We measure the sheet surface density and the magnetic field strength at that transition for the first time and show consistency with an analytical prediction that had previously gone untested for over 50 years (Mestel 1965)., Comment: 14 pages, 5 figures.

We achieved a concise total synthesis of salimabromide by using a novel intramolecular radical cyclization to simultaneously construct the unique benzo-fused [4.3.1] carbon skeleton and the vicinal quaternary stereocenters. Other notable transformations include a tandem Michael/Mukaiyama aldol reaction to introduce most of the molecule's structural elements, along with hidden information for late-stage transformations, an intriguing tandem oxidative cyclization of a diene to form the bridged butyrolactone and enone moieties spontaneously, and a highly enantioselective hydrogenation of a cycloheptenone derivative (97% ee) that paved the way for the asymmetric synthesis of salimabromide.

An improved reel take-up system for suppressing the aerial refueling hose whipping phenomenon (HWP) is proposed and analyzed. The conventional spring-loaded take-up system is improved by adding a rewinding acceleration changing rate limiter (RACRL), relying on a permanent magnet synchronous motor (PMSM). The effectiveness of this new reel take-up system is confirmed by the numerical simulation at various closure speeds. The results show that the new PMSM-RACRL reel take-up system successfully accomplishes the active control of tension oscillation and the suppressing of HWP with a straightforward strategy. The amplitude of tension oscillation is reduced to one-tenth of that without active control. It is also discovered that the reel take-up speed lagging behind the drogue closure speed is mainly caused by the oscillation of hose tension, and a maximum acceleration of the reel take-up system lower than the maximum closure acceleration of the drogue will inevitably cause the slack and whipping of the hose.

Sexual morph: Ascomata 100–180 μm high, 60–100 μm diam. (x̅ = 146.3 × 86.9 μm, n = 5), solitary, scattered, appear as black dots on the host surface, square to ellipsoidal, brown, immersed, apapillate, ostiolate. Peridium 10–20 μm wide, evenly thickened, comprising brown cells of textura angularis to textura prismatica, flattened and hyaline towards inner layers, fused with host tissues. Hamathecium comprising hyaline, cylindrical, guttulate, branched paraphyses (2–6 μm wide), arising from base of ascomata.

Ascospores 10–22 × 4–7 μm (x̅ = 16 × 5.5 μm, n = 15), hyaline, oval to fusiform, sometimes allantoid, straight or slightly curved, guttulate. Asexual morph: Undetermined Culture characteristics:— Colonies on PDA reaching 2 cm diam. after 2 weeks at 20–25 °C, medium dense, circular to slightly irregular, slightly raised, cottony surface smooth, at first white, becoming light yellow when mature, without any pigmentation; reverse yellowish-white. Material examined:— China, Sichuan Province, Chengdu, University of Electronic Science and Technology premises, on dead leaves of an unidentified poaceous host, September 2021, Q Wang W30 (KUN-HKAS127240, holotype), ex-type cultures KUNCC 23–13008 Known distribution:— Sichuan Province, China Notes:— Microdochium sichuanense morphologically resembles M. graminearum and M. shilinense in having solitary, scattered, immersed, apapillate, ostiolate ascomata, textura angularis to prismatica cells in peridium, 8- spored, biseriate with short stipe asci, and hyaline, guttulate, fusiform, straight or curved ascospores. Microdochium sichuanense differs from M. graminearum and M. shilinense in having clavate to oblong asci without an apical ring and aseptate ascospores, while M. graminearum and M. shilinense have fusiform asci with apical ring and 0–3 transversely septate ascospores. Multi-gene phylogenetic analyses (FIGURE 1) show that our collection forms a sister group with the isolates of M. hainanense (SAUCC 210781 and SAUCC 210782) with 60% ML and 0.96 BYPP. It is impossible to compare M. sichuanense and M.hainanense as they occur in different morphs (sexual and asexual). A pairwise nucleotide comparison between the two species showed that M. sichuanense differs from M. hainanense (SAUCC 210782) in 35/566 bp of ITS (6.18%) and 150/797 bp of rpb2 (18.82%). Interestingly, both species were collected from the same host family (Poaceae), but from different locations in China (M. sichuanense: Sichuan Province and M. hainanense: Hainan Province)., Published as part of Dissanayake, Lakmali S., Kang, Ji-Chuan & Maharachchikumbura, Sajeewa S.

Background. Tumor-associated macrophages (TAMs) are known to generate an immune-suppressive tumor microenvironment (TME) and promote tumor progression. Hepatocellular carcinoma (HCC) is a devastating disease that evolves in the background of chronic inflammatory liver damage. In this study, we aimed to uncover the mechanism by which HCC cells recruit macrophages into the TME. Methods. Bioinformatic analysis was performed to identify differentially expressed genes related to macrophage infiltration. An orthotopic HCC xenograft model was used to determine the role of macrophages in HCC tumor growth. Clodronate liposomes were used to delete macrophages. Western blotting analysis, quantitative real-time PCR, and enzyme-linked immunosorbent assay were performed to determine the underlying mechanisms. Results. The high mobility group A1 (HMGA1) gene was identified as a putative modulator of macrophage infiltration in HCC. Deletion of macrophages with clodronate liposomes significantly abrogated the tumor-promoting effects of HMGA1 on HCC growth. Mechanistically, HMGA1 can regulate the expression of C-C Motif Chemokine Ligand 2 (CCL2), also referred to as monocyte chemoattractant protein 1 (MCP1), which is responsible for macrophage recruitment. Moreover, NF-κB was required for HMGA1-mediated CCL2 expression. Pharmacological or genetic inhibition of NF-κB largely blocked CCL2 levels in HMGA1-overexpressing HCC cells. Conclusions. This study reveals HMGA1 as a crucial regulator of macrophage recruitment by activating NF-κB-CCL2 signaling, proves that HMGA1-induced HCC aggressiveness dependents on the macrophage, and provide an attractive target for therapeutic interventions in HCC.

Microvascular basement membrane (BM) plays a pivotal role in the interactions of astrocyte with endothelium to maintain the blood–brain barrier (BBB) homeostasis; however, the significance and precise regulation of the endothelial cell–derived BM component in the BBB remain incompletely understood. Here, we report that conditional knockout of Atg7 in endothelial cells (Atg7-ECKO) leads to astrocyte–microvascular disassociation in the brain. Our results reveal astrocytic endfeet detachment from microvessels and BBB leakage in Atg7-ECKO mice. Furthermore, we find that the absence of endothelial Atg7 downregulates the expression of fibronectin, a major BM component of the BBB, causing significantly reduced coverage of astrocytes along cerebral microvessels. We reveal Atg7 triggers the expression of endothelial fibronectin via regulating PKA activity to affect the phosphorylation of cAMP-responsive element-binding protein. These results suggest that Atg7-regulated endothelial fibronectin production is required for astrocytes adhesion to microvascular wall for maintaining the BBB homeostasis. Thus, endothelial Atg7 plays an essential role in astrocyte–endothelium interactions to maintain the BBB integrity.

Mayflies are one of the key members constituting aquatic ecosystems with their diverse roles in freshwater communities as a consumer and also as a prey. A burrowing mayfly, Ephemera orientalis McLachlan, widely distributed across the Korean streams, has recently become nuisance aquatic insects due to repeated local mass emergences in urban areas throughout spring to late summer. Despite its ecological and environmental importance in the aquatic ecosystems, the level of genetic diversity and genetic structures of E. orientalis populations remains unknown in South Korea. Here, we developed novel polymorphic microsatellite markers using a next generation sequencing (NGS) technique. A total of 18 populations across South Korea including massively emerging populations were then analyzed by using the developed microsatellites. Information on the level of genetic diversity and genetic structure of the Korean E. orientalis populations will facilitate understanding the level of interpopulation differentiation, effective population size, migrations between populations and origin of mass emerging populations of E. orientalis. Seven newly developed microsatellite markers in the present study would assist to reveal the spatial and temporal patterns of population dynamics of E. orientalis.

Submerged arc additive manufacturing (SAAM) is a viable technique for manufacturing large and complex specialized parts used in structural applications. At present, manufacturing high-strength low-alloy steel T-branch pipe through SAAM has not been reported. This paper uses this technology to manufacture low-alloy structural steel parts. The microstructures of the samples were characterized, which revealed that they were mainly composed of polygonal ferrites. The tensile properties in the horizontal and vertical directions of deposits were studied. Results show that the horizontal tensile strength of deposits was quite close to the vertical one, while the elongation rate in the vertical direction was obviously lower than that in the horizontal direction. Fatigue results indicate that the strain fatigue limit of high-strength low-alloy steel samples in vertical direction was 0.24%. The fatigue fractures of fatigue samples of deposits showed multi-source crack initiation characteristics and the crack propagation regions exhibited typical fatigue striations, so the final instantaneous fracture region showed a ductile fracture. Fatigue performance is very important for the safe service of structural parts, but there is a lack of relevant research on this additive manufacturing part. The results of this paper may support the popularization of the SAAM for high-strength low-alloy steel T-branch pipe.

To compare and analyze the biomechanical differences between different transosseous techniques in arthroscopic repairment of rotator cuff injuries by finite element analysis.Finite element models of traditional arthroscopic transosseous(ATO) technique, giant needle technique, and ArthroTunneler(AT) technique were established based on the shoulder CT data of a healthy adult. Then, loads of 10 N and 20 N were applied to the sutures on the different technical models, respectively. Compare and analyze the stress changes of the bone tunnels and sutures of the three models were compared and analyzed.Under the same condition of loading, the stress on the lateral bone tunnels and sutures of the traditional ATO technology model was the largest, followed by the giant needle technology model. The stress on the mid-section bone tunnels and sutures of the AT technology model was the largest, followed by the giant needle technology model. Under the different conditions of loading, the high-stress areas of the three models were mainly concentrated on the contact area between the sutures and the bone tunnels. Besides, compared with the traditional ATO technology model, the stress distribution of the lateral bone tunnels and sutures of the giant needle technology and AT technology model were more dispersed, but there was obvious stress concentration phenomena in the stress distribution in the mid-section bone tunnels and sutures in the AT technology model.Compared with the traditional ATO technique, both the giant needle technique and the AT technique can reduce the risk of cutout between the bone tunnel and suture, and may be better treatments for rotator cuff tear. However, compared with the giant needle technique, the application of AT technique in patients with osteoporosis may be limited.

We study the HII regions associated with the NGC 6334 molecular cloud observed in the sub-millimeter and taken as part of the B-fields In STar-forming Region Observations (BISTRO) Survey. In particular, we investigate the polarization patterns and magnetic field morphologies associated with these HII regions. Through polarization pattern and pressure calculation analyses, several of these bubbles indicate that the gas and magnetic field lines have been pushed away from the bubble, toward an almost tangential (to the bubble) magnetic field morphology. In the densest part of NGC 6334, where the magnetic field morphology is similar to an hourglass, the polarization observations do not exhibit observable impact from HII regions. We detect two nested radial polarization patterns in a bubble to the south of NGC 6334 that correspond to the previously observed bipolar structure in this bubble. Finally, using the results of this study, we present steps (incorporating computer vision; circular Hough Transform) that can be used in future studies to identify bubbles that have physically impacted magnetic field lines., Comment: Accepted for publication in Astrophysical Journal (ApJ)

International audience; Root mechanical traits, including tensile strength (Tr), tensile strain (εr), modulus of elasticity (Er) and tensile toughness (Wr), play a key role in plant functioning (e.g., anchorage and stem stability). Yet, their variability and their relationships with other root traits are poorly known. Here, we characterize Tr, εr, Er and Wr at both intra-and interspecific levels and examine how they covary with other root traits related to root economics space (RES). We used twelve herbaceous species from contrasting taxonomical families grown in controlled plein-air conditions. For each species, we excavated root systems and measured morphological and chemical traits and mechanical traits at two locations (proximal versus distal) for two root types (absorptive versus transport roots). Transport roots tended to show higher mechanical trait values than absorptive roots, especially for εr, while the location where the root was sampled showed a limited effect on root mechanics. The five monocots (Poaceae species) had higher mechanical traits than the seven dicots (including five Fabaceae species) except for Er. Root mechanical traits covaried positively and were strongly positively correlated with specific root length, i.e., a trait related to soil exploration strategy, and negatively with root diameter and root tissue density, i.e. a trait related to root life span. We demonstrate the important role of species category and root type in governing mechanical trait variation at both intra-and inter-specific levels. Our results can be regarded as the first evidence of the link between root mechanical robustness and the RES through a strong association with the 'do-it-yourself' soil exploration strategy.

Etymology: Referring to its collection location, Wuzhishan Mountain from where the species was first isolated (China). Saprobic on dead wood roots, forming on the host surface. Sexual morph: Stromata 0.3–0.8 cm long × 0.6–1.2 cm broad (x = 0.6 × 0.8 cm, n = 10), semiglobular or irregularly globose, whole stromata up to with flattened or slightly convex top. Surface of stromata black, with raised blackish dots. Perithecia 300–600 μm high × 200–400 μm diam. (x = 400 × 300 μm, n = 10), oval to spherical, embedded, closely arranged, interior white. Ostioles papillate, surrounded with white tissue. Asci 235–366 × 11–20 μm (x = 293 × 14.2 μm, n = 30), 8-spored, unitunicate, cylindrical, long-stipitate, apically rounded, with a J+, rectangular or urn-shaped, apical ring, blue staining in Melzer’s reagent, 6.7–10.5 μm (x = 8.7 μm, n = 30) high, 4.2–6.5 μm (x = 5.3 μm, n = 30) wide. Ascospores 23–30.5 × 7–9 μm (x = 26.5 × 8 μm, n=30), brown to black, unicellular, ellipsoid to inequilateral, with broadly rounded ends, smooth, with a conspicuous slanted germ slit nearly one-third spore-length, lacking appendages and sheaths. Asexual morph: Undetermined. Culture characteristics: Colonies on OA reaching 3–4 mm diam. after 2 weeks at 25 °C. White at first, white at first, upright, velvety with irregular outgrowths or furrows, with a peripheral fan-shaped extension spreading toward the edge; reverse light grey in the center, white marginal area. After 4 weeks, colonies on OA reaching 9 cm diam., white greyish, velvety or inflorescence, appressed with entire margins; reverse black, with brownish ring. No conidia were observed. Notes: Based on the multi-gene phylogenetic analyses (Fig. 1), X. wuzhishanensis is most closely related to X. schweinitzii. Morphologically, X. wuzhishanensis differs from X. schweinitzii by its semi-globular or irregularly globose stromata. Xylaria wuzhishanensis shows similar traits of X. atrosphaerica (Cooke & Massee) Callan & J.D. Rogers, X. globosa (Spreng. ex Fr.: Fr.) Mont., and X. lepidota Y.M. Ju et al. with semiglobular or irregularly globose stromata. But, X. wuzhishanensis can distinguish from X. atrosphaerica by its larger ascospores (23–30.5 × 7–9 μm vs. 17–25 × 6–10 μm) with a shorter germ slit (Callan et al. 1990). The surface of stroma lacks crackle of X. wuzhishanensis, which can make a distinction between X. globosa and X. lepidota (Ju et al. 2009, Fournier et al. 2018)., Published as part of Wu, You-Peng, Pi, Yin-Hui, Long, Si-Han, Liu, Li-Li, Zhang, Xu, Long, Qing-De, Lin, Yan, Kang, Ying-Qian, Kang, Ji-Chuan, Wijayawardene, Nalin N. & Li, Qi-Rui, 2022, Morphology and phylogeny reveal two novel Xylaria (Xylariaceae) species from China, pp. 130-146 in Phytotaxa 550 (2) on page 141, DOI: 10.11646/phytotaxa.550.2.3, http://zenodo.org/record/6641065, {"references":["Callan, B.

However, X. sylvatica is distinguish from X. spinulosa by its lacking long thorns on the stromatal surface, and larger ascospores (23–28.5 × 7–9.5 μm vs. 19–23 × 6.5–8.5 μm) with a sigmoid germ slit. Xylaria sylvatica differs from X. haemorrhoidalis by its upright, solitary, unbranched, cylindrical or clavate stromata (Li et al. 2017). Morphologically, Xylaria sylvatica shows similar traits of X. martinicensis J. Fourn. & Lechat., and X. squamulosa F. San Martín & J.D. Rogers., with upright, long stipitate, cylindrical or clavate stromata with fertile inflated at apex, conspicuous cracked or wrinkled on the surface of stromata. But, X. martinicensis have smaller ascospores (13–16.5 × 6–7.5 μm vs. 23–28.5 × 7–9.5 μm), with a narrow but conspicuous, straight, longitudinally oriented germ slit, which can make a distinction for X. sylvatica (Fournier et al. 2020). Xylaria squamulosa differs from X. sylvatica by larger ascospores (29–40 × 11–14 μm vs. 23–28.5 × 7–9.5 μm) with a straight germ slit nearly spore-length (San Martín et al. 1989)., Published as part of Wu, You-Peng, Pi, Yin-Hui, Long, Si-Han, Liu, Li-Li, Zhang, Xu, Long, Qing-De, Lin, Yan, Kang, Ying-Qian, Kang, Ji-Chuan, Wijayawardene, Nalin N. & Li, Qi-Rui, 2022, Morphology and phylogeny reveal two novel Xylaria (Xylariaceae) species from China, pp. 130-146 in Phytotaxa 550 (2) on pages 137-141, DOI: 10.11646/phytotaxa.550.2.3, http://zenodo.org/record/6641065, {"references":["Li, Q.

Tumor-associated macrophages (TAMs) are known to generate an immune-suppressive tumor microenvironment (TME) and promote tumor progression. Hepatocellular carcinoma (HCC) is a devastating disease that evolves in the background of chronic inflammatory liver damage. In this study, we aimed to uncover the mechanism by which HCC cells recruit macrophages into the TME.Bioinformatic analysis was performed to identify differentially expressed genes related to macrophage infiltration. An orthotopic HCC xenograft model was used to determine the role of macrophages in HCC tumor growth. Clodronate liposomes were used to delete macrophages. Western blotting analysis, quantitative real-time PCR, and enzyme-linked immunosorbent assay were performed to determine the underlying mechanisms.The high mobility group A1 (HMGA1) gene was identified as a putative modulator of macrophage infiltration in HCC. Deletion of macrophages with clodronate liposomes significantly abrogated the tumor-promoting effects of HMGA1 on HCC growth. Mechanistically, HMGA1 can regulate the expression of C-C Motif Chemokine Ligand 2 (CCL2), also referred to as monocyte chemoattractant protein 1 (MCP1), which is responsible for macrophage recruitment. Moreover, NF-This study reveals HMGA1 as a crucial regulator of macrophage recruitment by activating NF

Background The current surveillance system only focuses on notifiable infectious diseases in China. The arrival of the big-data era provides us a chance to elaborate on the full spectrum of infectious diseases. Methods In this population-based observational study, we used multiple health-related data extracted from the Shandong Multi-Center Healthcare Big Data Platform from January 2013 to June 2017 to estimate the incidence density and describe the epidemiological characteristics and dynamics of various infectious diseases in a population of 3,987,573 individuals in Shandong province, China. Results In total, 106,289 cases of 130 infectious diseases were diagnosed among the population, with an incidence density (ID) of 694.86 per 100,000 person-years. Besides 73,801 cases of 35 notifiable infectious diseases, 32,488 cases of 95 non-notifiable infectious diseases were identified. The overall ID continuously increased from 364.81 per 100,000 person-years in 2013 to 1071.80 per 100,000 person-years in 2017 (χ2 test for trend, P P Conclusions Infectious diseases remain a substantial public health problem, and non-notifiable diseases should not be neglected. Multi-source-based big data are beneficial to better understand the profile and dynamics of infectious diseases.

The aim of this study was to determine the effect of HDAC6 inhibition using the selective inhibitor Tubastatin A (TubA) on the regulation of tert-butyl hydroperoxide (TBHP)-treated chondrocytes and a mouse OA model. Using conventional molecular biology methods, our results showed that the level of HDAC6 increases both in the cartilage of osteoarthritis (OA) mice and TBHP-treated chondrocytes in vitro. TubA treatment effectively inhibits the expression of HDAC6, attenuates oxidative stress, reduces the level of apoptotic proteins to maintain chondrocyte survival, and suppresses the extracellular matrix (ECM) degradation. In addition, our results also revealed that HDAC6 inhibition by TubA activates autophagy in chondrocytes, whereas the protective effects of TubA were abolished by autophagy inhibitor intervention. Subsequently, the positive effects of HDAC6 inhibition by TubA were also found in a mouse OA model. Therefore, our study provide evidence that HDAC6 inhibition prevents OA development, and HDAC6 could be applied as a potential therapeutic target for OA management.
