Abstract

This study aimed to investigate serum levels of adiponectin, and the mRNA expression of forkhead box C2 (FOXC2) and glucose transporter-4 (GLUT4) in visceral adipose tissue obtained from patients with gestational diabetes mellitus (GDM) and healthy pregnant women. Venous blood samples were obtained from 60 pregnant women with gestational normal glucose tolerance (GNGT) and 21 patients with GDM. Visceral adipose tissues were obtained from 11 women with GDM and 30 with GNGT. Serum adiponectin levels were detected by enzyme-linked immunosorbent assay, and FOXC2 and GLUT4 mRNA expression were detected by quantitative polymerase chain reaction. Serum adiponectin concentrations were lower in the women with GDM than in the controls (p p p =.0564). Our results revealed that decreased adiponectin, FOXC2, and GLUT4 expression were associated with increased risk of GDM and the regulation mechanism of GLUT4 mediated by FOXC2 would be the focus of further studies.

Abstract

BACKGROUND: Protecting the intestinal mucosa from being destroyed helps reduce the inflammation caused by acute pancreatitis (AP). In this study, whether okra pectin (OP) could attenuate the inflammation of AP through protecting the intestinal barrier was investigated. RESULTS: OP was obtained from crude okra pectin (COP) through the purification by DEAE cellulose 52 column. Supplementation with OP or COP in advance reduced the severity of AP, as revealed by lower serum amylase and lipase levels, abated pancreatic edema, attenuated myeloperoxidase activity and pancreas histology. OP or COP inhibited the production of pancreatic proinflammatory cytokines, including tumor necrosis factor‐α and interleukin‐6. In addition, the upregulation of AP‐related proteins including ZO‐1, occludin, the antibacterial peptide‐defensin‐1 (DEFB1) and cathelicidin‐related antimicrobial peptide (CRAMP), as well as the histological examination of colon injuries, demonstrated that OP or COP provision could effectively maintain intestinal barrier function. Ultimately, dietary OP or COP supplementation could inhibit AP‐induced intestinal inflammation. For the above, the effect of OP was better than COP. CONCLUSION: Dietary OP supplementation could be considered as a preventive method that effectively interferes with intestinal damage and attenuates inflammatory responses trigged by AP. © 2020 Society of Chemical Industry [ABSTRACT FROM AUTHOR]

Abstract

Cascade isothermal nucleic acid amplification, which integrates several different amplification protocols to enhance the assay performance, is widely utilized in biosensing, particularly for detecting microRNAs (miRNAs), crucial biomarkers associated with tumor initiation and progression. However, striking a balance between a high amplification efficiency and simplicity in design remains a challenge. Therefore, methods achieving high amplification efficiency without significantly increasing complexity are highly favored. In this study, we propose a novel approach for miRNA detection, employing cross-priming-linked hierarchical isothermal amplification (CP-HIA) to progressively activate the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a system. The CP-HIA method strategically combines nicking-rolling circle amplification (n-RCA) and palindrome-aided circular strand displacement amplification (p-CSDA) for miRNA detection. Remarkably, this method utilizes only two main probes. Its key innovation lies in the interactive cross-priming strategy, wherein the amplification product from n-RCA is recycled to further drive p-CSDA, and vice versa. This interactive process establishes a hierarchical amplification, significantly enriching the activation probes for progressive CRISPR/Cas12a activation and subsequent target signal amplification. Consequently, the method exhibits greatly enhanced analytical performance, including high sensitivity and specificity in detecting low concentrations of miRNA. As low as 1.06 fM miRNA can thus be quantitatively detected, and the linear response of the miRNA is from 10 fM to 10 nM. These features demonstrate its potential for early disease diagnosis and monitoring. We anticipate that the CP-HIA method will serve as a promising platform for developing advanced molecular diagnostic tools for biomedical research.

Abstract

In recent years, natural disasters such as sudden changes in climate, earthquakes, typhoons, storms, and snowstorms have occurred frequently around the world, which have greatly threatened the survival and development of human beings. Many countries in the world are seeking a balanced development between economic development and natural environment. Among them, low-carbon economy is the priority choice, which has been accepted by all countries in the world. A low-carbon economy characterized by low energy consumption, low pollution and low emissions has become the mainstream trend in today's world. As a concept with a relatively broad connotation, the digital economy can be included in any economic form that directly or indirectly uses data to guide resources to play a role and promote the development of productivity. In this context, the driving mechanism of the digital economy for the development of low-carbon industries has also become one of the issues that every-one pays attention to. DEA (Data Envelope Analysis) is a linear programming model expressed as the ratio of output to input. It attempts to maximize the efficiency of a service unit by comparing the efficiency of a particular unit with the performance of a group of similar units providing the same service. In response to the above problems, this paper would use the DEA model to analyze the impact of the interaction between low-carbon industries and finance. It indirectly shows the relationship between the digital economy and the driving mechanism of low-carbon industry development. The experimental research shows that: under the same other conditions, there is an obvious positive relationship between environmental protection investment and financing and its output value. That is to say, the more the amount of environmental protection investment and financing in the low-carbon industry, the higher the industrial output value, which shows that the environmental protection financing has a good role in promoting the driving mechanism of the development of the low-carbon industry. It is confirmed that the digital economy can promote the driving mechanism of low-carbon industry development.

Abstract

Willingness to Communicate (WTC) has been “proposed as one of the key concept in L2 learning and instruction” (Kang, 2005, p. 278). This study examined Chinese English learners’ WTC in an Intensive English program (IEP) in the US. The study used both the WTC Survey and semi-structured interview to identify the variables that impact Chinese students’ WTC and how different language environment (China and America) affects their WTC. There were a total of 12 participants who filled out the Survey and 11 of them were interviewed. The Survey results indicated that there was one participant who tended to talk less which matched with the participants’ interview answer. Interview data showed that there were various factors impacting students’ WTC. The significant finding from this study was that the participants all became more willing to communicate after they studied in IEP. It indicated the predisposition of L2 (second language) WTC does not remain the same across from various situations, in addition, there are different variables impact WTC.

Abstract

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a family inherited cardiomyopathy associated with ventricular arrhythmias. With the development of molecular biology, histology, imaging, and other diagnostic techniques, the diagnosis rate and incidence of ARVC have gradually increased. However, ARVC remains rare in clinical practice. Currently, the diagnosis and management of ARVC is far from satisfactory in clinical practice. In the case report, we described a clinical case of radiofrequency ablation guided by voltage mapping and right ventriculography in the treatment of ARVC with ventricular tachycardia and discussed the relevant literatures., (© 2024.

Abstract

Objective: To know about the cesarean section rate and the changes of the indications for cesarean section in Changsha from 2008 to 2017, and to provide scientific basis for decreasing the cesarean section rate.
 Methods: We collected the clinical data of deliveries in a general hospital in Changsha from January 2008 to December 2017, and analyzed the cesarean section rate, the changes of the indications for cesarean section and the influential factors. 
 Results: The cesarean section rate in this hospital was 50.0% from 2008 to 2017, and the cesarean section due to social factors showed a decreasing trend year by year. Multiple-factor analysis of the cesarean section shows that advanced age, multi-parous pregnancy, gravida (≥4 times), abnormal fetal position and heavy fetus weight were dangerous factors, and the multipara was a protective factor.
 Conclusion: The cesarean section rate in a general hospital in Changsha is at a high level, and there are many factors affecting cesarean section. It is necessary to optimize the strategies and measures to reduce the cesarean section rate, and to control the cesarean section rate in a reasonable range.

Abstract

The magnesium transporter 1 (MAGT1) is a critical regulator of basal intracellular free magnesium ([Mg 2+ ]i) levels. It has been shown that MAGT1 was involved in the disorder in Mg 2+ homeostasis after Epstein-Barr virus (EBV) infection. Here, we identified the effects of MAGT1-mediated disturbance of Mg 2+ homeostasis on chronic hepatitis B virus (HBV)-infected natural killer (NK) and CD8 + T cells. The expression of MAGT1 was gradually decreased with the increase of infected time in CD8 + T cells, but not with that in NK cells, of the patients. Decreased level of intracellular free Mg 2+ ([Mg 2+ ]i) leads to defective expression of programmed cell death 1 (PD-1) and the NK activating receptor (NKG2D) in NK and CD8 + T cells. Our data illustrate that [Mg 2+ ]i plays a key role in control of HBV infection.
