Abstract
We present a search for subsolar mass ultracompact objects in data obtained during Advanced LIGO's second observing run. In contrast to a previous search of Advanced LIGO data from the first observing run, this search includes the effects of component spin on the gravitational waveform. We identify no viable gravitational-wave candidates consistent with subsolar mass ultracompact binaries with at least one component between 0.2 M_{⊙}-1.0 M_{⊙}. We use the null result to constrain the binary merger rate of (0.2 M_{⊙}, 0.2 M_{⊙}) binaries to be less than 3.7×10^{5} Gpc^{-3} yr^{-1} and the binary merger rate of (1.0 M_{⊙}, 1.0 M_{⊙}) binaries to be less than 5.2×10^{3} Gpc^{-3} yr^{-1}. Subsolar mass ultracompact objects are not expected to form via known stellar evolution channels, though it has been suggested that primordial density fluctuations or particle dark matter with cooling mechanisms and/or nuclear interactions could form black holes with subsolar masses. Assuming a particular primordial black hole (PBH) formation model, we constrain a population of merging 0.2 M_{⊙} black holes to account for less than 16% of the dark matter density and a population of merging 1.0 M_{⊙} black holes to account for less than 2% of the dark matter density. We discuss how constraints on the merger rate and dark matter fraction may be extended to arbitrary black hole population models that predict subsolar mass binaries.

System-Wide Characterization of MoArf GTPase Family Proteins and Adaptor Protein MoGga1 Involved in the Development and Pathogenicity of Magnaporthe oryzae. mBio 2019; 10:e02398-19.

Abstract
ADP ribosylation factor (Arf) small GTPase family members are involved in vesicle trafficking and organelle maintenance in organisms ranging from Saccharomyces cerevisiae to humans. A previous study identified Magnaporthe oryzae Arf6 (MoArf6) as one of the Arf proteins that regulates growth and conidiation in the rice blast fungus M. oryzae, but the remaining family proteins remain unknown. Here, we identified six additional Arf proteins, including MoArf1, MoArl1, MoArl3, MoArl8, MoCin4, and MoSar1, as well as their sole adaptor protein, MoGga1, and determined their shared and specific functions. We showed that the majority of these proteins exhibit positive regulatory functions, most notably, in growth. Importantly, MoArl1, MoCin4, and MoGga1 are involved in pathogenicity through the regulation of host penetration and invasive hyphal growth. MoArl1 and MoCin4 also regulate normal vesicle trafficking, and MoCin4 further controls the formation of the biotrophic interfacial complex (BIC). Moreover, we showed that Golgi-cytoplasm cycling of MoArl1 is required for its function. Finally, we demonstrated that interactions between MoArf1 and MoArl1 with MoGga1 are important for Golgi localization and pathogenicity. Collectively, our findings revealed the shared and specific functions of Arf family members in M. oryzae and shed light on how these proteins function through conserved mechanisms to govern growth, transport, and virulence of the blast fungus.IMPORTANCEMagnaporthe oryzae is the causal agent of rice blast, representing the most devastating diseases of rice worldwide, which results in losses of amounts of rice that could feed more than 60 million people each year. Arf (ADP ribosylation factor) small GTPase family proteins are involved in vesicle trafficking and organelle maintenance in eukaryotic cells. To investigate the function of Arf family proteins in M. oryzae, we systematically characterized all seven Arf proteins and found that they have shared and specific functions in governing the growth, development, and pathogenicity of the blast fungus. We have also identified the pathogenicity-related protein MoGga1 as the common adaptor of MoArf1 and MoArl1. Our findings are important because they provide the first comprehensive characterization of the Arf GTPase family proteins and their adaptor protein MoGga1 functioning in a plant-pathogenic fungus, which could help to reveal new fungicide targets to control this devastating disease.

Abstract
Objective: To validate whether the prognostic stage groups by the 8th edition of the American Joint Committee on Cancer (AJCC) staging system provides improved prognostic accuracy in T1-2N1M0 postmastectomy breast cancer patients compared to 7th edition. Methods: a total of 1 823 female patients with T1-2N1M0 breast cancer who underwent mastectomy and axillary lymph node dissection without neoadjuvant chemotherapy were analyzed and restaged according to 8th edition. Univariate analysis of prognostic factors was evaluated by using log-rank test. Multivariate analysis was estimated by using the Cox proportional hazards model. The prognostic accuracy of the two staging systems was compared using receiver operating characteristic (ROC) analyses and the concordance index (C-index). Results: 5-year locoregional recurrence rate (LRR) for the whole group was 6.0%, 5-year distant metastasis (DM) rate was 11.5%, 5-year disease-free survival (DFS) was 85.0%, and 5-year overall survival (OS) was 93.1%. Cox analysis showed that 7th edition of the AJCC staging system and progesterone receptor status were independent risk factors for LRR, DM, DFS and OS (P<0.05). Compared with stage by 7th edition, 1 278(70.1%) were assigned to a different prognostic stage group: 1 088 (85.1%) to a lower stage and 190 (14.9%) to a higher stage. LRR, DM, DFS and OS were significantly different between prognostic stage ⅠA, ⅠB, ⅡA, ⅡB and ⅢA according to 8th edition of the AJCC staging system(P<0.001). Prognostic stage had significantly higher C-indexes and provided better estimation of prognosis compared to stage by 7th edition of the AJCC staging system (P<0.001). Conclusion: The prognostic stage groups of 8th edition AJCC staging system has superior prognostic accuracy compared to 7th edition in T1-2N1M0 breast cancer, and has better clinical therapeutic guidance value.

Abstract
With the extensive use of sentinel lymph node biopsy (SLNB), some breast cancer patients could avoid axillary lymph node dissection (ALND) and its complications. Neoadjuvant chemotherapy plays an important role in the multimodality therapies of breast cancer. After neoadjuvant chemotherapy, some patients with breast cancer were down-staged from positive axillary lymph node (cN+ ) to clinically negative (cN0). For these patients, the feasibility and safety of sentinel lymph node biopsy remains controversial. However, with the application of new technologies, SLNB is expected to become the main treatment for breast cancer patients with stage cN0 after neoadjuvant chemotherapy.

Abstract
Cells are faced with various stresses during their growth and development, and autophagy is a degradative process in which cells can break down their own components to recycle macromolecules and provide energy under these stresses. For pathogenic fungi that utilize cell wall as the first barrier against external stress, the cell wall integrity (CWI) pathway also provides an essential role in responding to these stresses. However, the specific connection between autophagy and CWI remains elusive in either the model fungi including budding yeast Saccharomyces cerevisiae or the rice blast fungus Magnaporthe oryzae. Here, we provided evidence that the endoplasmic reticulum (ER) stress is highly induced during M. oryzae infection and that CWI MAP kinase kinase MoMkk1 (S. cerevisiae Mkk1/2 homolog) was subject to phosphorylation regulation by MoAtg1, the only identified kinase in the core autophagy machinery. We also identified MoMkk1 serine 115 as the MoAtg1-dependent phosphorylation site and this phosphorylation could activate CWI, similar to that by the conserved MAP kinase kinase kinase MoMck1 (S. cerevisiae Bck1 homolog). Together with the first report of MoMkk1 subjects to phosphorylation regulation by MoAtg1, we revealed a new mechanism by which autophagy coordinates with CWI signaling under ER stress, and this MoAtg1-dependent MoMkk1 phosphorylation is essential for the pathogenicity of M. oryzae.Abbreviations: A/Ala: alanine; Atg: autophagy-related; Bck1: bypass of C kinase 1; co-IP: co-immunoprecipitation; CWI: cell wall integrity;DTT: dithiothreitol; ER: endoplasmic reticulum; GFP: green fluorescent protein; Mo: Magnaporthe oryzae; MAPK: mitogen-activated protein kinase; Mkk1: mitogen-activated protein kinase-kinase 1; MS: mass spectrometry; PAS: phagophore assembly site; RFP: red fluorescent protein; RT: room temperature; S/Ser: serine; Slt2: suppressor of the lytic phenotype 2; T/Thr: threonine; UPR: unfolded protein response; Y2H: yeast two-hybrid screen.

Abstract
The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source. This source, for the first time, permits tests of strong-field dynamics of compact binaries in the presence of matter. In this Letter, we place constraints on the dipole radiation and possible deviations from GR in the post-Newtonian coefficients that govern the inspiral regime. Bounds on modified dispersion of gravitational waves are obtained; in combination with information from the observed electromagnetic counterpart we can also constrain effects due to large extra dimensions. Finally, the polarization content of the gravitational wave signal is studied. The results of all tests performed here show good agreement with GR.

Abstract
Objectives
Diet plays a significant role in the carcinogenesis. However, few studies had been conducted to evaluate the association of dietary mineral intake and risk of cervical intraepithelial neoplasia (CIN) and cervical cancer among community-based Chinese women.
Methods
We performed a cross-sectional analysis of screening data in 2304 women in an ongoing cohort of 40,000 women in China. Multivariable logistic regressions were modeled to evaluate the relationship between dietary mineral intake and CIN + risk.
Results
After adjusting for multiple confounders, several dietary minerals intake were significantly associated with CIN2 + risk. Dietary calcium intake concentration was associated with the risk of CIN2 + (1st quartile versus 4th quartile: OR = 1.52, 95% CI: 1.01–2.32). The similar results were also observed for magnesium (OR = 1.80, 95% CI: 1.20–2.68), phosphorus (OR = 1.69, 95% CI: 1.12–2.55), zinc (OR = 1.55, 95% CI: 1.03–2.34) and potassium (OR = 1.92, 95% CI: 1.28–2.88). The association between dietary calcium intake and CIN1 risk (2nd quartile compared with 4th quartile: OR = 1.36, 95% CI: 1.03, 1.80), potassium (OR = 1.90, 95% CI: 1.27, 2.85). However, seldom statistical association was observed between other dietary mineral intake and CIN1 risk.
Conclusions
Dietary nutrients such as calcium, magnesium, phosphorus, zinc, and potassium were associated with risk of CIN2+, supporting the hypothesis that dietary mineral intake play a role in the development of higher grad CIN and cervical cancer.

Abstract
Objective: To investigate the effects of sucralfate suspension gel (SC) on Helicobacter pylori (H.pylori) colonization, H.pylori-induced gastric mucosal injury and gastrointestinal microecology in mice. Methods: C57BL/6J mice were randomly divided into 3 groups, including normal control (NC) group, H.pylori model (HP) group, and SC prevention (HP+SC) group. H.pylori infection mouse model was established by gavage with H.pylori Sydney strain (SS1). And HP+SC group was also administered with SC for 14 days. After mice were sacrificed, the gastric mucosa was taken for HE staining, immunohistochemical (IHC) staining [H.pylori, zonula occludens-1 (ZO-1), Occludin, interleukin (IL)-8, IL-10 and tumor necrosis factor-α (TNF-α)], qPCR (IL-8, IL-10, TNF-α) . And cell ultrastructure was observed by electron microscopy. Microbiota communities in the gastric mucosa or fecal were investigated using 16S ribosomal RNA (rRNA) gene sequencing. The detection of H.pylori in IHC staining or Giemsa staining was defined as H.pylori infection. Results: The H.pylori positive rate of HP group was 91.67%, and that of HP+SC group was 50.00%. The EDS of HP group were significantly higher than those of the NC group [(3.42±0.19) vs (1.17±0.17), P<0.05], while EDS of HP+SC group (2.42±0.29) were significantly lower than that of HP group (P<0.05). The mRNA levels and immunostaining scores of IL-8, IL-10 and TNF-α in HP group was higher than NC group (all P<0.05). Compared with HP group, mRNA levels and IHC scores of IL-8 significantly decreased (all P<0.05) in HP+SC group, while those of IL-10 and TNF-α was similar between two groups (all P>0.05). The IHC scores of ZO-1 and Occludin in HP group was significantly lower than NC group (all P<0.05), and that of ZO-1 and Occludin in the HP+SC group increased compared with HP group [(2.00±0.26) vs (1.17±0.48), P>0.05; (3.50±0.43) vs (2.33±0.21), P<0.05]. Compared with NC group, the diversity of gastric microbiota in HP group was significantly lower, and diversity of gut microbiota decreased insignificantly. There was no significant difference between HP+SC group and HP group in gastric or gut microbiota. Conclusion: SC reduces H.pylori colonization, protects H.pylori-induced gastric mucosal injury, decreases H.pylori-induced IL-8 expression, enhances Occludin. However, its effects on H.pylori-induced gastrointestinal microbiota disorders are limited.

Abstract
BACKGROUND Parents who lost their only child and can not conceive another child, are known as shidu parents in China. This study aimed to estimate the prevalence of post-traumatic stress disorder (PTSD) and examine the mediating role of perceived stress between hope and PTSD symptoms in Chinese shidu parents. METHODS 295 shidu mothers and 197 shidu fathers were recruited in Shenyang city. Shidu parents were asked to complete a questionnaire including the PTSD Checklist for DSM-5 (PCL-5), the Herth hope index (HHI) and the Perceived Stress Scale-10 (PSS-10). Hierarchical linear regression was performed to assess the associations among hope, perceived stress and PTSD symptoms. Asymptotic and resampling strategies were used to explore the mediating role of perceived stress. RESULTS The prevalence of PTSD in Chinese shidu parents was 23.78%. Mothers were more likely to develop PTSD than fathers. For shidu fathers, the proportion of mediation of perceived stress was 39.48%. For shidu mothers, the proportion of mediation of perceived stress was 40.00%. LIMITATIONS Due to the cross-sectional design, the findings of the present study can not be used to establish formal causal relationships or to determine the direction of causality. Longitudinal studies are need to validate our findings. CONCLUSIONS Perceived stress partly mediated the relationship between hope and PTSD symptoms in Chinese shidu parents. The interventions of hope and perceived stress should be included in PTSD prevention. More assistance should be directed to improve the mental health of shidu mothers.

Abstract
In the original compression tracking algorithm, the size of the tracking box is fixed. There should be better tracking results for scale-invariant objects, but worse tracking results for scale-variant objects. To overcome this defect, a scale-adaptive compressive tracking (CT) algorithm is proposed. First of all, the imbalance of the gray and texture features in the original CT algorithm is balanced by the multi-feature method, which makes the algorithm more robust. Then, searching different candidate regions by using the method of multi-scale search along with feature normalization makes the features extracted from different scales comparable. Finally, the candidate region with the maximum discriminate degree is selected as the object region. Thus, the tracking-box size is adaptive. The experimental results show that when the object scale changes, the improving CT algorithm has higher accuracy and robustness than the original CT algorithm.

Abstract
Luminescent solar concentrators (LSCs) have attracted significant attention as promising solar energy conversion devices for building integrated photovoltaic (PV) systems due to their simple architecture and cost-effective fabrication. Conventional LSCs are generally comprised of an optical waveguide slab with embedded emissive species and coupled PV cells. Colloidal semiconductor quantum dots (QDs) have been demonstrated as efficient emissive species for high-performance LSCs because of their outstanding optical properties including tunable absorption and emission spectra covering the ultraviolet/visible to near-infrared region, high photoluminescence quantum yield, large absorption cross sections, and considerable photostability. However, current commonly used QDs for high-performance LSCs consist of highly toxic heavy metals (i.e., cadmium and lead), which are fatal to human health and the environment. In this regard, it is highly desired that heavy metal-free and environmentally friendly QD-based LSCs are comprehensively studied. Here, notable advances and developments of LSCs based on unary, binary, and ternary eco-friendly QDs are presented. The synthetic approaches, optical properties of these eco-friendly QDs, and consequent device performance of QD-based LSCs are discussed in detail. A brief outlook pointing out the existing challenges and prospective developments of eco-friendly QD-based LSCs is provided, offering guidelines for future device optimizations and commercialization.

Abstract
Direct atomic-scale observations and measurements on dynamics of amorphous metallic nanoparticles (a-NPs) are challenging owing to the insufficient consciousness to their striking characterizations and the difficulties in technological approaches. In this study, we observe coalescence process of the a-NPs at atomic scale. We measure the viscosity of the a-NPs through the particles coalescence by in situ method. We find that the a-NPs have fast dynamics, and the viscosity of the a-NPs exhibits a power law relationship with size of the a-NPs. The a-NPs with sizes smaller than 3 nm are in a supercooled liquid state and exhibit liquid-like behaviours with a decreased viscosity by four orders of magnitude lower than that of bulk glasses. These results reveal the intrinsic flow characteristics of glasses in low demension, and pave a way to understand the liquid-like behaviours of low dimension glass, and are also of key interest to develop size-controlled nanodevices. Nanoscale materials often exhibit size-dependent behaviour. Here, the authors use electron microscopy to quantitatively study the size-related dynamics of amorphous metallic nanoparticles, finding that particles below a critical size are in a supercooled liquid state at room temperature, with a viscosity much lower than that of bulk glasses.

Abstract
Objective: To investigate the clinical efficacy of laparoscopic subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy (SCBCAC) in the treatment of senile slow transit constipation. Methods: A retrospective cohort study was performed. Clinical data of 30 colonic slow transit constipation patients aged ≥70 years old undergoing laparoscopic SCBCAC from July 2012 to October 2016 (bypass plus colostomy group), and 28 patients undergoing laparoscopic subtotal colonic bypass with antiperistaltic cecoproctostomy (SCBAC) from February 2009 to June 2012 (bypass group) at our institute were collected. Efficacy was compared between the two procedures. Inclusion criteria: (1) meeting the Rome III diagnosis criteria for constipation; (2) confirmed diagnosis of slow transit constipation; (3) age ≥ 70 years old; (4) receiving non-surgical treatment for more than 5 years, and Wexner constipation score > 15; (5) follow-up for more than 2 years. Those with psychiatric symptoms or previous psychiatric history, obvious signs of outlet obstructive constipation, organic diseases of the colon and life-threatening cardiovascular diseases or cancer were excluded. In the bypass plus colostomy group, laparoscopy was performed via five trocars. The ileocecal junction and the ascending colon were mobilized and the ileocecal junction was pulled down to the pelvic inlet. The ascending colon was transected and the appendix was excised. The lateral peritoneum of the sigmoid colon and the rectal mesentery were dissected and the upper rectum was transected. The avil of a circular stapler was placed in the bottom of the cecum. The shaft of the stapler was placed in the rectum via the anal canal to complete end-to-side anastomosis (end rectum to lateral cecum). The end of the rectal-sigmoid colon was used for colostomy via an extraperitoneal approach to complete the operation. The following efficacy indexes were collected before surgery and 3, 6, 12, and 24 months after surgery: the number of daily bowel movements, the Wexner incontinence scale (WIS, 0-20, the lower the better), the Wexner constipation scale (WCS, 0-30, the lower the better), the gastrointestinal quality of life index (GIQLI, 0-144, the higher score, the better), abdominal pain intensity indicated by the numerical rating scale (NRS, 0-10, the lower score, the better), and the abdominal bloating score (ABS, 0-4, the lower score, the better). The complications defined as Clavien-Dindo class II or above were observed and recorded. Results: No significant differences in preoperative WCS, WIS, GIQLI, NRS, and ABS were observed between bypass plus colostomy group and bypass group (all P>0.05). All the patients successfully underwent laparoscopic surgery and no patient in either group experienced postoperative fecal incontinence. WCS and GIQLI were significantly improved (all P<0.001) at 3, 6, 12, and 24 months after surgery in both groups. At 12 months after surgery, the number of bowel movements was significantly less in bypass plus colostomy group than that in bypass group [(2.4±0.7) times vs. (3.4±1.2) times, t=4.048, P<0.001]. At 3, 6, 12 and 24 months after surgery, the improvement of GIQLI in bypass plus colostomy group was significantly better than that in bypass group (all P<0.001). At 24 months after surgery, GIQLI in bypass plus colostomy group and bypass group was 122.3±5.3 and 92.8±16.6, respectively, with a significant difference (t=9.276, P<0.001). At 12 and 24 months after surgery, NRS in bypass plus colostomy group was significantly better than that in bypass group (both P<0.001). At 24 months after surgery, NRS in bypass plus colostomy group was 0.9±0.7, while that in bypass group was 3.7±2.7. There was a significant difference between two groups (t=5.585, P<0.001). At 6, 12 and 24 months after surgery, the improvement of ABS in bypass plus colostomy group was also significantly better than that in bypass group. At 24 months after surgery, ABS in bypass plus colostomy group was 0.6±0.6, while that in bypass group was 2.5±1.0, with a significant difference between two groups (t=8.797, P<0.001). At 1 year after surgery, barium enema examination was performed in all the patients of both groups. The barium emptying time was (21.2±3.8) hours and (95.8±86.2) hours in bypass plus colostomy group and bypass group respectively. The former group was significantly better than the latter group (t=4.740, P<0.001). Conclusions: Laparoscopic SCBCAC is an effective and safe procedure for the treatment of senile slow transit constipation and can significantly improve prognosis. Its clinical efficacy is better than laparoscopic SCBAC.

Abstract
We analyze the impact of a proposed tidal instability coupling p modes and g modes within neutron stars on GW170817. This nonresonant instability transfers energy from the orbit of the binary to internal modes of the stars, accelerating the gravitational-wave driven inspiral. We model the impact of this instability on the phasing of the gravitational wave signal using three parameters per star: an overall amplitude, a saturation frequency, and a spectral index. Incorporating these additional parameters, we compute the Bayes factor (lnB_{!pg}^{pg}) comparing our p-g model to a standard one. We find that the observed signal is consistent with waveform models that neglect p-g effects, with lnB_{!pg}^{pg}=0.03_{-0.58}^{+0.70} (maximum a posteriori and 90% credible region). By injecting simulated signals that do not include p-g effects and recovering them with the p-g model, we show that there is a ≃50% probability of obtaining similar lnB_{!pg}^{pg} even when p-g effects are absent. We find that the p-g amplitude for 1.4 M_{⊙} neutron stars is constrained to less than a few tenths of the theoretical maximum, with maxima a posteriori near one-tenth this maximum and p-g saturation frequency ∼70 Hz. This suggests that there are less than a few hundred excited modes, assuming they all saturate by wave breaking. For comparison, theoretical upper bounds suggest ≲10^{3} modes saturate by wave breaking. Thus, the measured constraints only rule out extreme values of the p-g parameters. They also imply that the instability dissipates ≲10^{51} erg over the entire inspiral, i.e., less than a few percent of the energy radiated as gravitational waves.

Abstract
Objective: To investigate the clinical and prognostic differences between primary nasopharyngeal natural killer (NK)/T-cell lymphoma (NP NKTCL) and extranodal NK/T-cell lymphoma of the nasal cavity with nasopharynx extension (N-NP NKTCL). Methods: A total of 89 patients with NP NKTCL and 113 patients with N-NP NKTCL from January 2000 to June 2015 were retrospectively analyzed. Clinical and pathological features, treatment responses and prognosis were compared between the two groups. Results: NP NKTCL patients showed similar clinicopathological features with those with N-NP NKTCL, except that the former had a relative low proportion of elevated lactate dehydrogenase (LDH) levels (28.1% vs. 41.6%; P=0.001). Both of two groups presented with high proportion of cervical lymph node involvement (55.1% and 42.5%; P=0.076). The 5-year overall survival (OS) rates in these two groups were 63.2% and 54.6%, respectively, whereas 5-year progress-free survival (PFS) rates were 50.7% and 45.6%, respectively. For the patients with stage Ⅰ and Ⅱ, the 5-year OS and PFS rates in these two groups were 68.8% and 55.7% as well as 55.6% and 47.2%, respectively. These were no statistically significant differences between two groups (all P>0.05). The complete response (CR) rate after initial chemotherapy in NP NKTCL group was 43.8%, which was significant higher than that of 19.6% in N-NP NKTCL group (P=0.006). Additionally, the CR rate after primary radiotherapy was 63.4% and 62.7%, respectively (P=0.629). The NP NKTCL patients with stage Ⅰ and Ⅱ who accepted radiotherapy with or without chemotherapy had similar survival times with chemotherapy alone, showing the 5-year OS rates of 70.5% and 33.3% (P=0.238), as well as the 5-year PFS rates of 56.7% and 33.3%, respectively (P=0.431). Similar results were found in N-NP NKTCL group, the 5-year OS rates for patients with radiotherapy with or without chemotherapy and chemotherapy alone were 57.4% and 33.3% (P=0.246), while the 5-year PFS rates were 49.3% and 16.7% (P=0.177), respectively. Besides, the relapse pattern of NP NKTCL and N-NP NKTCL groups was also similar, mainly involving the distant extra-nodal organs followed by lymph nodes. Conclusion: The patients with N-NP NKTCL and NP NKTCL showed similar clinical and prognostic features, however, the initial response to chemotherapy was different.

The seven transmembrane domain protein MoRgs7 functions in surface perception and undergoes coronin MoCrn1-dependent endocytosis in complex with Gα subunit MoMagA to promote cAMP signaling and appressorium formation in Magnaporthe oryzae. PLoS Pathog 2019; 15:e1007382.

Abstract
Regulator of G-protein signaling (RGS) proteins primarily function as GTPase-accelerating proteins (GAPs) to promote GTP hydrolysis of Gα subunits, thereby regulating G-protein mediated signal transduction. RGS proteins could also contain additional domains such as GoLoco to inhibit GDP dissociation. The rice blast fungus Magnaporthe oryzae encodes eight RGS and RGS-like proteins (MoRgs1 to MoRgs8) that have shared and distinct functions in growth, appressorium formation and pathogenicity. Interestingly, MoRgs7 and MoRgs8 contain a C-terminal seven-transmembrane domain (7-TM) motif typical of G-protein coupled receptor (GPCR) proteins, in addition to the conserved RGS domain. We found that MoRgs7, but not MoRgs8, couples with Gα MoMagA to undergo endocytic transport from the plasma membrane to the endosome upon sensing of surface hydrophobicity. We also found that MoRgs7 can interact with hydrophobic surfaces via a hydrophobic interaction, leading to the perception of environmental hydrophobiccues. Moreover, we found that MoRgs7-MoMagA endocytosis is regulated by actin patch-associated protein MoCrn1, linking it to cAMP signaling. Our studies provided evidence suggesting that MoRgs7 could also function in a GPCR-like manner to sense environmental signals and it, together with additional proteins of diverse functions, promotes cAMP signaling required for developmental processes underlying appressorium function and pathogenicity.

The suppressive effects of miR-508-5p on the odontogenic differentiation of human dental pulp stem cells by targeting glycoprotein non-metastatic melanomal protein B. Stem Cell Res Ther 2019; 10:35. [PMID: 30670091 PMCID: PMC6341723 DOI: 10.1186/s13287-019-1146-8] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2018] [Accepted: 01/10/2019] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Although the involvement of glycoprotein non-metastatic melanomal protein B (GPNMB) in regulating the odontogenic differentiation of human dental pulp stem cells (hDPCs) has been identified, the underlying mechanisms are largely unknown. The purpose of this study is to investigate the effects of miR-508-5p on the GPNMB expression and the odontogenic differentiation of hDPCs. METHODS In this study, hDPCs were isolated and identified by flow cytometric analysis. Based on bioinformatics analysis, dual luciferase reporter assay was performed to verify GPNMB acting as a target of miR-508-5p. The regulatory roles of miR-508-5p in odontogenetic differentiation of hDPCs were investigated through its inhibition or overexpression (miRNA mimics and miRNA inhibitors). qRT-PCR and Western blot analysis were used to detect the expression of odontogenetic marker genes and proteins. The assays of alkaline phosphatase (ALP) activity and Alizarin Red S staining were performed to evaluate the odontogenetic phenotype. RESULTS We first found that the levels of miR-508-5p expression decreased gradually during odontogenesis of hDPCs, while the expressions of GPNMB were upregulated obviously. The suppressive effects of miR-508-5p on GPNMB were determined by oligonucleotide transfection in hDPCs and dual luciferase reporter assay in 293T cells. Subsequently, the significant inhibition of hDPC odontogenesis after the overexpression of miR-508-5p was observed, which is consistent with the decreased expression levels of several odontoblast-specific genes, such as dentin matrix protein 1 (DMP-1), dentin sialophosphoprotein (DSPP), and osteocalcin (OCN), as well as the decreased activity of ALP and weakened Alizarin Red S staining. Furthermore, ectopic expression of GPNMB (lacking 3'-UTR) rescued the effects of miR-508-5p on odontogenic differentiation. CONCLUSIONS Our study demonstrated that miR-508-5p regulated the osteogenesis of hDPCs by targeting GPNMB and provided novel insight into the critical roles of microRNAs in hDPC differentiation.

Abstract
Despite the high prevalence of cognitive impairment among older adults, little is known about the association of the selection of dexmedetomidine and propofol on cognitive functions of patients after a critical illness. Patients aged ≥70 years who received intensive care unit (ICU) care from Cangzhou Central Hospital between 2013 and 2016 were enrolled and randomized into a dexmedetomidine group and a propofol group with matched demographic and clinical characteristics. At discharge from the ICU and 4 weeks later, the cognitive status of patients was assessed and compared using the Montreal Cognitive Assessment system. There were 164 patients included in the dexmedetomidine group and 159 patients in the propofol group. No significant difference was observed between the 2 groups in terms of age, female sex, body weight, educational level, ICU and hospital stay, comorbidities, and medications. Further, patients from the 2 groups at ICU discharge did not demonstrate significant difference on the Montreal Cognitive Assessment component scores, which showed significant differences between the 2 groups 4 weeks later (P < .05). Moreover, dexmedetomidine and propofol showed different levels of impacts on the cognitive function of patients discharged from the postanesthesia care unit, neurological ICU, and medical ICU. This study demonstrated that patients discharged from the ICU who received propofol for sedation showed less impairment on the cognitive functions when compared with patients who received dexmedetomidine during ICU care 4 weeks after discharge. Despite some limitations, this study provides insights to the decision-making process in the selection of appropriate sedation strategy, especially for the elderly patients.

N-propyl functionalized spherical mesoporous silica as a rapid and efficient adsorbent for steroid estrogen removal: Adsorption behaviour and effects of water chemistry. CHEMOSPHERE 2019; 214:361-370. [PMID: 30267909 DOI: 10.1016/j.chemosphere.2018.09.115] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/14/2018] [Revised: 09/15/2018] [Accepted: 09/18/2018] [Indexed: 05/24/2023]
Abstract
To achieve an enhanced and selective adsorption of steroid estrogens, the n-propyl functionalization was applied to the mesoporous silica material (MCM-41) according to the physico-chemical property analysis of steroid estrogens. Adsorption behaviour and water chemistry effects were evaluated with the most concerned steroid estrogens: estrone (E1), 17β-estradiol (E2) and 17α-ethinyl estradiol (EE2) based on the materials characterization. The results showed the uptakes of E1, E2, and EE2 onto the modified MCM-41 were enhanced and accelerated by the n-propyl functionalization, which was positively correlated with the hydrophobicity of the synthesized materials. Kinetic data fitted the pseudo-second-order model well. Based on the Langmuir model, the maximum adsorption capacities of the n-propyl modified MCM-41 were up to 119.87, 88.38, and 86.91 mg g-1 for EE2, E1, and E2, respectively. Importantly, both acid and neutral solutions were beneficial to estrogen removal, but ionic strength and humic acid did not affect the estrogen adsorption. The above results suggested that the n-propyl functionalized MCM-41 would be a promising adsorbent for the rapid and efficient removal of estrogens with the selectivity from natural organic matter like humic acid. Mechanism analysis showed the key role of hydrophobic interaction, and it also confirmed the contribution of the carbonylic lone pair electrons of E1, which helped the formation of stronger hydrogen bonds with silicon hydroxyls and enhanced the dipole-dipole interaction between E1 and the synthesized materials.

Abstract
The hierarchical item response theory (H-IRT) model is very flexible and allows a general factor and subfactors within an overall structure of two or more levels. When an H-IRT model with a large number of dimensions is used for an adaptive test, the computational burden associated with interim scoring and selection of subsequent items is heavy. An alternative approach for any high-dimension adaptive test is to reduce dimensionality for interim scoring and item selection and then revert to full dimensionality for final score reporting, thereby significantly reducing the computational burden. This study compared the accuracy and efficiency of final scoring for multidimensional, local multidimensional, and unidimensional item selection and interim scoring methods, using both simulated and real item pools. The simulation study was conducted under 10 conditions (i.e., five test lengths and two H-IRT models) with a simulated sample of 10,000 students. The study with the real item pool was conducted using item parameters from an actual 45-item adaptive test with a simulated sample of 10,000 students. Results indicate that the theta estimations provided by the local multidimensional and unidimensional item selection and interim scoring methods were relatively as accurate as the theta estimation provided by the multidimensional item selection and interim scoring method, especially during the real item pool study. In addition, the multidimensional method required the longest computation time and the unidimensional method required the shortest computation time.
