Abstract
Background The present study aimed to compare the effectiveness and safety of low molecular-weight-heparin (LMWH) and unfractionated heparin (UFH) in acute myocardial infarction (AMI) patients receiving intra-aortic balloon counterpulsation (IABP).
Materials and Methods We retrospectively analyzed a total of 344 patients receiving IABP for cardiogenic shock, severe heart failure, ventricular septal rupture, or mitral valve prolapse due to AMI. A total of 161 patients received UFH (a bolus injection 70 U/kg immediately after IABP, followed by infusion at a rate of 15 U/kg/hour and titration to for 50 to 70 seconds of activated partial thromboplastin time. A total of 183 patients received LMWH (subcutaneous injection of 1.0 mg/kg every 12 hours for 5 to 7 days and 1.0 mg/kg every 24 hours thereafter). Events of ischemia, arterial thrombosis or embolism, and bleeding during IABP were evaluated. Major bleeding was defined as a hemoglobin decrease by >50 g/L (vs. prior to IABP) or bleeding that caused hemodynamic shock or life-threatening or requiring blood transfusion.
Results Subjects receiving UFH and LMWH did not differ in baseline characteristics. Ischemia was noted in five (3.1%) and two (1.1%) subjects in UFH and LMWH groups, respectively. Arterial thromboembolism occurred in three (1.9%) subjects in the UFH group, but not in the LMWH group. Logistic regression analysis failed to reveal an association between ischemia or bleeding with heparin type. Major bleeding occurred in 16 (9.9%) and six (3.3%) patients in the UFH and LWMH groups, respectively (p = 0.014). Regression analysis indicated that LMWH is associated with less major bleeding.
Conclusion LMWH could reduce the risk of major bleeding in patients receiving IABP. Whether LMWH could reduce arterial thromboembolism needs further investigation.

On the nature of AA question1
in Yi2 and related problems
Authors: Zhang Heyou , Wuni Muji 
Published: September 2020

Abstract
This paper aims to study a kind of interrogative in Yi which surfaces as an AA form commonly viewed as
AA/Reduplicative Question. It explores the interrogative motivation, question type, generative mechanism and syntactic derivation
of AA Question. We first assume that (i) AA question in Yi is a kind of alternative question, which is reduced successively from
A-or-not-A and A-not-A question and (ii) the [+Q] feature of AA question does not result from reduplication but from other
reasons. To justify these two assumptions, we use tests including adverb tests, modal tests, tag question tests, SFP tests, Q
& A tests, and cross-language investigation and sociolinguistic survey. The findings include (i) the [+Q] feature of AA
question results from the existence of an abstract interrogative morpheme, (ii) the phenomenon of reduplication is just a kind of
byproduct with the syntactic derivation of AA question and (iii) AA question, diachronically speaking, is essentially a kind of
alternative question, which is reduced successively from A-or-not-A and A-not-A question to meet the economic principle of
language.
Speech acts in corpus pragmatics
Authors: Weisser Martin 
Published: September 2020

Abstract
In corpus pragmatics, most of the research into speech acts still tends to be limited to working with the original, highly
abstract, speech-act taxonomies devised by ordinary language philosophers like Austin and Searle. The aim of this article is to illustrate
how the use of such restricted taxonomies may lead to oversimplified or potentially misleading impressions regarding the communicative
functions expressed in spoken interaction, and to demonstrate how a more elaborate taxonomy, the DART taxonomy (Weisser, 2018), may help us gain better insights into the pragmatic strategies that occur in dialogues. To this end,
I will draw on a small sample of dialogues, both from a task-oriented domain and unconstrained interaction, and contrast selected speech-act
categorisations on the basis of Searle’s and the DART taxonomy, demonstrating the advantages that arise from using a more fine-grained
taxonomy to describe complex verbal exchanges.

Abstract

Objective. Magnetoencephalography (MEG) based brain–computer interface (BCI) involves a large number of sensors allowing better spatiotemporal resolution for assessing brain activity patterns. There have been many efforts to develop BCI using MEG with high accuracy, though an increase in the number of channels (NoC) means an increase in computational complexity. However, not all sensors necessarily contribute significantly to an increase in classification accuracy (CA) and specifically in the case of MEG-based BCI no channel selection methodology has been performed. Therefore, this study investigates the effect of channel selection on the performance of MEG-based BCI. Approach. MEG data were recorded for two sessions from 15 healthy participants performing motor imagery, cognitive imagery and a mixed imagery task pair using a unique paradigm. Performance of four state-of-the-art channel selection methods (i.e. Class-Correlation, ReliefF, Random Forest, and Infinite Latent Feature Selection were applied across six binary tasks in three different frequency bands) were evaluated in this study on two state-of-the-art features, i.e. bandpower and common spatial pattern (CSP). Main results. All four methods provided a statistically significant increase in CA compared to a baseline method using all gradiometer sensors, i.e. 204 channels with band-power features from alpha (8–12 Hz), beta (13–30 Hz), or broadband (α + β) (8–30 Hz). It is also observed that the alpha frequency band performed better than the beta and broadband frequency bands. The performance of the beta band gave the lowest CA compared with the other two bands. Channel selection improved accuracy irrespective of feature types. Moreover, all the methods reduced the NoC significantly, from 204 to a range of 1–25, using bandpower as a feature and from 15 to 105 for CSP. The optimal channel number also varied not only in each session but also for each participant. Reducing the NoC will help to decrease the computational cost and maintain numerical stability in cases of low trial numbers. Significance. The study showed significant improvement in performance of MEG-BCI with channel selection irrespective of feature type and hence can be successfully applied for BCI applications.

Abstract
The introduction of two-photon polymerization (2PP) to the field of tissue engineering and regenerative medicine (TERM) has led to great expectations for the production of scaffolds with an unprecedented degree of complexity and tailorable architecture. Unfortunately, resolution and size are usually mutually exclusive when using 2PP, resulting in a lack of highly-detailed scaffolds with a relevant size for clinical application. Through the combination of using a highly reactive photopolymer and optimizing key printing parameters, we propose for the first time a biodegradable and biocompatible poly(trimethylene-carbonate) (PTMC)-based scaffold of large size (18 × 18 × 0.9 mm) with a volume of 292 mm3 produced using 2PP. This increase in size results in a significant volumetric increase by almost an order of magnitude compared to previously available large-scale structures (Stichel 2010 J. Laser Micro./Nanoeng.
5 209–12). The structure’s detailed design resulted in a highly porous scaffold (96%) with excellent cytocompatibility, supporting the attachment, proliferation and differentiation of human adipose-derived mesenchymal stem cells towards their osteogenic and chondrogenic lineages. This work strongly attests that 2PP is becoming a highly suitable technique for producing large-sized scaffolds with a complex architecture. We show as a proof-of-concept that an arrayed design of repetitive units can be produced, but a further perspective will be to print scaffolds with anisotropic features that are more representative of human tissues.
Direct extrusion of individually encapsulated endothelial and smooth muscle cells mimicking blood vessel structures and vascular native cell alignment

AbstractCardiovascular diseases (CVDs) are considered the principal cause of worldwide death, being atherosclerosis the main etiology. Up to now, the predominant treatment for CVDs has been bypass surgery from autologous source. However, due to previous harvest or the type of disease, this is not always an option. For this reason, tissue engineered blood vessels (TEBV) emerged as an alternative graft source for blood vessel replacement. In order to develop a TEBV, it should mimic the architecture of a native blood vessel encapsulating the specific vascular cells in their respective layers with native alignment, and with appropriate mechanical stability. Here, we propose the extrusion of two different cell encapsulating hydrogels, mainly alginate and collagen, and a sacrificial polymer, through a triple coaxial nozzle, which in contact with a crosslinking solution allows the formation of bilayered hollow fibers, mimicking the architecture of native blood vessels. Prior to extrusion, the innermost cell encapsulating hydrogel was loaded with human umbilical vein endothelial cells (HUVECs), whereas the outer hydrogel was loaded with human aortic smooth muscle cells (HASMCs). The size of the TEVB could be controlled by changing the injection speed, presenting homogeneity between the constructs. The obtained structures were robust, allowing its manipulation as well as the perfusion of liquids. Both cell types presented high rates of survival after the extrusion process as well as after 20 d in culture (over 90%). Additionally, a high percentage of HASMC and HUVEC were aligned perpendicular and parallel to the TEBV, respectively, in their own layers, resembling the physiological arrangement foundin vivo. Our approach enables the rapid formation of TEBV-like structures presenting high cell viability and allowing proliferation and natural alignment of vascular cells.

Abstract
Conventional 2D or even 3D in vitro culture models for human reproductive organs cannot properly recapitulate the bidirectional endocrine crosstalk between the uterine endometrium and the ovary. This crosstalk is essential for maintaining the various physiological features and functions of each tissue. Moreover, most in vitro models for the female reproductive tract also fail to mimic its multicellular structure. We therefore developed a novel ‘dual reproductive organ on a chip’ that reflects the bidirectional endocrine cross-talk and the complex multicellular structures by integrating various cellular components of both the human uterine endometrium and the ovary with several biodegradable natural polymers. Indeed, the bidirectional endocrine crosstalk between these two tissues is achieved through media sharing between channels, and it can markedly improve the viability of loaded cells within each chamber of the chip platform. In addition, we also identified a reliable reproductive toxicity marker, SERPINB2, which is significantly increased in response to various toxic exposures in both endometrial and ovarian follicular cells. Based on these findings, we next established a SERPINB2 luciferase reporter system that was specifically designed for detecting and quantifying the toxicity of certain substances. By introducing this SERPINB2 luciferase reporter system into the loaded cells within the chip platform, we ultimately developed an effective ‘dual reproductive organ-on-chip’ that was successfully used to predict the reproductive toxicity of various hazardous materials.

Authors: Martin Randy , Tram Kathlynn , Le Lan , Simmons Crystal 
Published: September 2020

Abstract

Purpose
The purpose of this study was to evaluate the financial performance and reimbursement of chronic care management (CCM) provided by clinical pharmacists in a primary care setting using Current Procedural Terminology codes that were added to the Medicare Physician Fee Schedule in 2017.

Methods
A retrospective study assessing financial performance of pharmacist-led CCM was conducted for the 12-month period from May 1, 2018, through April 30, 2019, at an academic multiclinic medical practice. Pharmacist-led CCM encounters included a combination of telephone and in-clinic visits. Return on investment, a ratio of net income to financial investment, was the primary outcome. Secondary outcomes included the number of CCM encounters, time spent by pharmacists delivering CCM (ie, “time-on-task”), and third-party claim reimbursement.

Result
Sixty-five patients were enrolled in CCM during the 12-month study period. Pharmacists provided 236 CCM encounters, including 31 enrollment visits and 102 hours of clinical time-on-task. Gross revenue for CCM during the 12-month period was $7,433.91, and expenses totaled $6,430.36, resulting in a 15.6% return on investment. Out of 158 CCM claims, 131 (83%) were paid and 27 (17%) were unpaid or remained in adjudication at study completion.

Conclusion
Pharmacist-led CCM resulted in a modest positive return on investment compared to other reimbursable pharmacy services. Practitioners should evaluate opportunities to synergize CCM with other fee-for-service and quality-based reimbursement programs.
Dux facilitates post-implantation development, but is not essential for zygotic genome activation†

Published: September 2020

AbstractDouble homeobox genes are unique to eutherian mammals. It has been proposed that the DUXC clade of the double homeobox gene family, which is present in multicopy long tandem arrays, plays an essential role in zygotic genome activation (ZGA). We generated a deletion of the tandem array encoding the DUXC gene of mouse, Double homeobox (Dux), and found it surprisingly to be homozygous viable and fertile. We characterize the embryonic development and ZGA profile of knockout (KO) embryos, finding that zygotic genome activation still occurs, with only modest alterations in 2-cell embryo gene expression, no defect in in vivo preimplantation development, but an increased likelihood of post-implantation developmental failure, leading to correspondingly smaller litter sizes in the KO strain. While all known 2-cell specific Dux target genes are still expressed in the KO, a subset is expressed at lower levels. These include numerous genes involved in methylation, blastocyst development, and trophectoderm/placental development. We propose that rather than driving ZGA, which is a process common throughout the animal kingdom, DUXC genes facilitate a process unique to eutherian mammals, namely the post-implantation development enabled by an invasive placenta.
Pleiotropic role of prokineticin 1 in the porcine endometrium during pregnancy establishment and embryo implantation †
Authors: Goryszewska Ewelina , Kaczynski Piotr , Baryla Monika , Waclawik Agnieszka 
Published: September 2020

Abstract
Acquisition of endometrial receptivity for embryo implantation is one of the crucial processes during pregnancy and is induced mainly by progesterone and enhanced by conceptus signals. Prokineticin 1 (PROK1) is characterized as a secretory protein with diverse functions in various tissues, including the reproductive tract. PROK1, with its receptor PROKR1, are up-regulated in the porcine endometrium during implantation and in women’s receptive endometrium and decidua. However, the function of PROK1 in embryo-maternal communication has still not been fully elucidated. Hence, we hypothesize that PROK1 is involved in endometrial receptivity development and implantation in pigs. In this study, using the porcine in vivo model of intrauterine infusions of estradiol-17β (E2) and prostaglandin E2 (PGE2), we revealed that these hormones elevated endometrial expression of PROK1 and PROKR1 mRNA, respectively. Moreover, E2, acting synergistically with PGE2, increased PROKR1 protein expression. We also evidenced that PROK1–PROKR1 signaling induced expression of following genes and/or proteins CCN2, CDH13, FGF2, NFATC2, ANGPT1, ANGPT2, CDH1, MUC4, SPP1, IFNG, IL6, LIF, LIFR, TNF, TGFB3, and FGF9, as well as phosphorylation of PTK2 and secretion of IL6 and IL11 by endometrial explants in vitro. Ingenuity pathway analysis revealed that functions associated with the PROK1-regulated genes/proteins include cell-to-cell contact, cell attachment, migration and viability, differentiation of epithelial tissue, leukocyte migration, inflammatory response, angiogenesis, and vasculogenesis. Summarizing, our study suggests that PROK1 acts pleiotropically as an embryonic signal mediator that regulates endometrial receptivity by increasing the expression of the genes and proteins involved in implantation and pregnancy establishment in pigs.
Kindergarten for Free?! Empirical Evidence on the Utilization of Income Tax Deductions for Child Care Expenses
Authors: Calahorrano Lena , Stöwhase Sven 
Published: September 2020

AbstractIn most developed countries there exist ample possibilities for individuals to minimize their personal income tax burden by means of tax deductions. The associated revenue losses for the government have been estimated for a variety of tax deductions. However, relatively little is known about the share of eligible taxpayers who actually use these deductions, and, more specifically, about what determines utilization. The present paper tries to shed some light on this question in the context of the tax deductibility of expenses for child care in Germany. Using survey data on actual child care expenses and official tax-return data on deductions for child-care expenses, we derive utilization rates. We also analyze the determinants of utilization among those who filed a tax-return, using a subsample of the tax-return data. Our estimation results show that (potential) tax breaks from utilization are significantly positively correlated with the probability of utilization. Other kinds of deductions are also highly significant, suggesting that knowledge of tax statutes as well as opportunity costs matter. Moreover, we simulate the effects of a policy reform that enhances the generosity of deductions on the utilization rate. Such a reform would substantially increase utilization. Our results indicate that responses in utilization are more important than potential responses in labor supply. (JEL codes: D14, H24, H43).
